The present invention relates to an apparatus for
positloning an object in a location.
This application is a divisional application of copend-
ing application No. 252,176 filed May 11, 1976.
Leaf springs are commonly used in vibratory systems to
isolate vibrations. A plurality of leaf-type springs have been
. ~
j used to support the receptacle of a vibratory conveyor. Burgess
discloses in U.S. Patent No. 2,985,280 a vibrating conveyor
supported on a plurality of leaf springs. Leaf springs have also
been used in punch machines to hold a work supporting structure,
as the structure for mounting the punch. Rabinow et al disclose
in U.S. Patent No. 3,123,290 a punch having a pair of cantilever
spring members connected to a punch block. A similar structure
is shown by Frohrib in U.S. Patent No. 3,742,800. Gartner in
U.S. Patent No. 2,727,122 shows a welder having electrodes
~ supported by cantilever spring members.
j Armature winding machines are equipped with flyer
structures that rotate to wind coils of wire on an armature core.
After the winding procedure has been completed, the wound core
must be unloaded from the machine and replaced with an unwound
core. The wire guiding chucks or shrouds of the machine must be
moved away from the core to permit the armature to be readily
removed from the machine. The machine must be equipped with
linearly or laterally movable flyers and/or shrouds which can be
moved to a release position relative to the core of the armature.
When a new and unwound armature is put into the machine, the
shrouds and wire winding flyers must be moved back to their wire
winding position. Linearly movable structures have a degree of
play which must be compensated for so that the flyers and chucks
can be accurately positioned adjacent the cores at all times.
The flyer structure must be rotated during the winding operation.
The drive mechanism for rotating the flyers must be laterally
1055537
moved during the movement of the flyers and shrouds to their
release position. This requires a specifically designed drive
structure which is costly to manufacture and occupies space in
the machine.
The present invention is directed to an object position-
ing apparatus that utilizes flexure means to mount the object on
a support. More specifically, the invention is directed to an
armature wire winding apparatus having means to wind wire onto
the core of an armature and flexure means to~mount the wire wind-
~ 10 ing means on a support. A control means is operable to move the
-~ wire winding means to a release position against the biasing force
~ of the flexure means and against other biasing means. When the
'~ force of the control means is released and reversed, the biasingmeans returns the wire winding means to the wire winding position
adjacent the core of the armature.
, The flexure means includes plate beam assemblies that
j are secured to the support and housing structure of the armaturewinding means. The control means includes a plate connected to
7 the housing and a fluid motor operable to move the plate and thehousing to a release position against the biasing force of the
, plate beam assemblies and against other biasing means. The fluid; motor is operable to apply a reverse force to the plates wherebythe housings and wire winding means are returned to their initial
wire winding positions.
The present invention provides a flexure mounting
C structure for the flyers and chucks of an armature winding machine
that are operable to positively position the flyers and chucks in
; a wire winding position. The invention also provides flexible
plate beam assemblies for mounting the wire winding structure of
an armature winding machine which does not have significant play
and accurately repositions the chucks in operative relation
adjacent the sides of a core.
The present invention further provides a plate beam
1055537
¦ mounting assembly for an armature core winding machine that can
be flexed in response to an actuation force to separate the
chucks from an armature core allowing the apparatus to be un-
loaded and loaded with a new core or permit the indexing of the
armature.
The present invention still further provides an armature
? winding apparatus with flexure beam mounting means that does notalter the timing of the drive system for the flyers of the arma-
ture winding machine. The present invention also provides an
,~ 10 armature winding mechanism with a mounting structure that utilizes
a minimum amount of space, has a minimum number of parts and can
be assembled with a minimum of time and labor in comparison with
previous designs. The present invention further provides a
flexure mount for an object having flexible plate beams that can
be easily and quickly assembled on a machine and can be replaced
~ with a minimum of time and cost.
j The present invention also provides a flexure mount
structure for wire winding apparatus of an armature core winding
machine that has accurate and repetitive motion, does not require
adjustment and does not wear over a long period of time. The
invention again provides a flexure mount structure for a wire
¦ winding apparatus that permits the timing belt to be mounted
directly on the winding shaft instead of through a spline, as the
flexure mount structure provides slack for the timing belt when
it is moved from its drive position.

Apparatus 10 comprises a first mechanism indicated gener-
ally at 16 facing a second mechanism indicated generally at 17.
Armatllrc core 13 is located betwcen mecha]lisms 16 an(l 17 so that
two wires can be simultaneously wound on the slotted armature
core.13. Mechanisms 16 and 17 are mounted on a support 18. As
shown in Figure 4, support 18 is a horizontal "I" beam having a
generally vertical web 19. Supnort 18 is-mounted on frame struc-
ture 21 which locates the mecllanisms 16 and 17 at a convenient
wor~ing height.

- ~echanisms 16 and 17 are identical in structure. The
following description is specific to the mechanism 16. The
corresponding parts of mechanism 17 have identical rcfcrcnce
numbers with the suffix A. As shown in Figure 2, mechanism 16
has upright end members or blocks 22 and 23. Each block 22 and
23 has a top section and a bottom section. Each section has a
semicircular cutout providing a hole 24 extended tllrougll the
block. A plurality of bolts 26 secure the top sections of the
block to the bottom sections of the blocks.
Blocks 22 and 23 are connected to support 18 with a mount-
ing flexure means indicated generally at 27. Flexure means 27
comprises a first flat upri~ht plate beam assembly 28 and a
second flat upright plate beam assembly 29. As shown in Figurc
3, assembly 28 is comprised of a plurality of 1at plate members
28B, 28C, 28D and 28E. The number and thickness of each plate
member can vary. Also, assembly 28 can be a single plate member.
Members 28B, 28C, 28D and 28E are metal, preferably stecl or
slmilar high strength material.
As shown in Figure 2, the lower transverse section of plate
beam assembly 28 is secured to a first bar 31. Bar 31 has a
key 31B located in groove 18B extended along the top of support
18. A plurality of bolts 30 secure bar 31 to support lS. Beam
members 28B, 28C, 28D and 28E have short projections, tangs, or
keys 28K located in groove 18B. The lower edges of beam members
28B, 28C, 28D and 28E are in engagement with the top surface of
support 18. Kcys 31B, 2S~ and groovc 18B provicle accuratc and
easy assembly and positioning of beam assembly 28, both verti-
cally and horizontally, on support lS. A second bar 32 accom-
modating bolts 33 secures the lower section of plate beam
assembly 28 to first bar 31. The upper transverse section of
plate beam assembly 28 is secured to the lowcr part of bloc~
22. A transverse bar 34 accommodating fastening mcans 36, as
-- 8
-
1055537
bolts threaded into the block 22, securely fasten the upper
section of plate beam assembly 28 to block 22.
The second plate beam asscmbly 29 has a lower transverse
section located adjacent a first bar 37. Beam assembly 29 has
a projection, key or tang 29K located in groovc 18B. Bar 37
has a p-rojection, key or tang 37B located in groove 18B. A
plurality of bolts 35 secure bar 37 to support 18. A second
bar 38 accommodating a plurality of bolts 39 is located opposite
the first bar 37. The bolts 39 are threaded into the first bar
37 to fasten the lower transverse section of plate beam assembly
29 to bar 37. A transverse bar 41 is located adjacent the upper
transverse portion of plate beam assembly 29. A plurality of
bolts 42 extend through bar 41, through the upper section of
plate beam assembly 29, and are threaded into the lower end of
block 23.
Plate beam assemblies 28 and 29 are flat plate members
commonly known as cantilever beams. The beams are secured at
their lower ends and are attached to the load, i.e., blocks 22
and 23, at their upper ends. Plate beam assemblies 28 and 29
normally locate the blocks 22 and 23 in a first or selected
position wherein blocks 22 and 23 are in side-by-side upright
positions. Blocks 22 and 23 can be laterally moved witll an
external force whereby beam assemblies 28 and 29 are deflected.
When the force on blocks 22 and 23 is reversed, the beam assem-
blies 28 and 29 will return the blocks 22 and 23 to their first
or norm~l positions. A tension coil spring 40, shown in ~igure
1, biases the mechallisms 16 and 17 to their wire winding posi-
tions. Anchor bolts 40A and 40B secure opposite ends of spring
40 to plates 61 and 61A. Other types of biasing means can be
used to urge the mechanisms to their wire winding positions.
Beam assemblies 28 and 29 also support the blocks 22 and 23
on tlle stationary "I" beam 18.
1055537
Blocks 22 and 23 are bearing blocks which accommodate a
rotatable shaft 43. Shaft 43 is rotatably mounted in a ball
bearing 44 located in hole 24 in block 22. A sleeve 46 is
rotatably mounted on shaft 43. Sleeve 46 is carried by a ball
bearing 47 located in opening 24 in block 23. Sleeve 46 projects
outwardly from block 23 and is secured to a disc 48 having an
outwardly directed arms 49 and 51. Arm 49 is a tubular member
or flyer that carries a wire 52 around the core 13 so that the
wire is wound on the core. Arm 51 is a balancing member to
compensate for the weight of arm 49. A pulley 53 is mounted
on the portion of the sleeve 46 located between the blocks 22
and 23. A gear box 55 having a first output shaft 56 drives an
endless belt 54 to rotate pulley 53. A second output shaft 56A
connected to gear box 55 drives a second belt 54A to rotate
pulley 53A. Pulleys 53 and 53A are rotated in opposite direc-
tions. A fluid motor 60 is operable to transmit power to
gear box 55. Other types of drives or power transmissions can
be used to rotate the sleeves 46 and 46A. For example, separate
motors can be connected to the drive belts 54 and 54A.
A wire guiding assembly or shroud 57 is mounted on the end
of shaft 43 adjacent disc 48. As shown in Figure 5, shroud 57
has an arcuate recess accommodating an arcuate segment of core
13 and converging wire guiding faces 59 for directing the wire
52 into pairs of slots in core 13. Shrouds 57 and 57A also
provide a clamp support for core 13.
As shown in Figllre 5, a plate 61 extends bet~eell the
~locks 22 and 23 and extends downlYardly adjacellt t]le side Or
the support 18. Bolts 62 secure plate 61 to blocks 22 and 23.
Bolts 62A secure the side plate 61A to blocks 22A and 23A.
A control mechanism indicated generally at 63, shown in
Figure 5, is used to move mechanisms 16 and 17 in opposite dir-
ections, as indicated by arrows 64 to spread shrouds 57 and 57A
-- 10 --
~055537
whereby the armature can be removed from holder 14. Control
mechanism 63 works against the biasing forces of tlle mounting
flexure means 27 and the biasing force of spring 40. When tl-e
force of the control mechanism 63 acting on side plates 61 and
61A is reversed, the mounting flexure means 27 and sprin~ 40
will.return the mechanisms 16 and 17 to their initial positions,
locating shrouds adjacent opposite sides of core 13. Control
mechanism 63 has a movable member 66 rotatably mounted on a
fixed axle 67. Axle 67 is secured to a base 68. A plurality
of bolts 69 secure the base 68 to the web 19 of the "I" beam
support 18. A first link 71 is connected with a pivot pin 72
to the top part of member 66. A yoke on link 71 is connected
- with a pin 73 to a bottom part of side plate 61. Link 71 is a
two-piece threaded member which can be rotated to change its
effective length. The lower end of member 66 is connected to
a second link 74 witll a pin 76. Lin~ 74 has a yoke 77 carry-
ing a pin 78 which connects the lower portion of side member 61A
to the yoke. Link 74 is identical to link 71.
A fluid motor indicated generally at 79, as an air cylinder,
hydraulic cylinder or the like, is used to rotate the member 66
on the axle 67. Motor 79 is connected to control means (not
shown) operable to control the operation of the motor in a timed
relation with the operation of motor 60. Motor 79 is preferably
a double-acting air cylinder 81 carrying a movable piston rod
82. Piston rod 82 is connected to the pin 76, as shown in
~i~ure 4, wllerehy the force of the motoT is tr.~nsmitte-l to tl~c
member 66. The opposite end of motor 79 is pivotllly mou-ltc-l
on an anchor 83. A plurality of bolts 84 secure the ancllor S~
to the "I" beam support 18.
In use, the fluid motor 79 is actuated to extend the piston
rod 82 in an outward direction moving the member 66 in a counter-
cloc~wise direction about axle 67. The lower end of member 61
-- 11 --
1055537
moves outwardly in the direction of arrow 64. The force is
transmitted through links 71 and 74 to move the side plates 61
and 61A away from each other. Plate beam assemblies 28, 29,
28A and 29A are subjected to equal opposite forces that flex
the plate springs. This moves the shrouds 57 and 57A away from
each other so that the armature can be removed from between the -
apparatus.
When the fluid pressure to the motor 79 is reversed, the
member 66 will be returned to its upright position. The plate
beam assemblies 28, 29, 28~ and 29A will return the shrouds
57 and 57A back to the initial armature holding positions in
response to the reverse force of the fluid motor 79.
Referring to ~igures 6-9, there is shown an apparatus for
winding coils of wire indicated generally at 100 on an armature
101. Armature 101 has an upright shaft 102 carrying a slotted
core 103. The lower end of shaft 102 is releasably held in an
upright holder 104. The lower end of the holder is operatively
connected to an indexing mechanism such as an electric motor
106. Holder 104 includes a cup member forming part of a com-
mutator shielding and lcad moving and guidin~ unit. The unitis operative to move and guide each ending wire lead which extends
from the coil just wound about the shaft and around a selected
commutator hook. lhe cntirc commutator, cxcept for a selected
hook, is shielded to prevent other or previously attached leads
from leaving their hooks. An cxample of this structure is shown
in U. S. Patent No. 3,636,621. The coil leads can be attached
to the commutator with the apparatus and method disclosed in
U. S. Patent No. 3,911,563. Motor 106 is drivably connected
to a drivc structurc (not shown) locatcd within or adjacent holder
104 opcrablc to impart minute incrcmcnts of rotation and thereby
index the core 103 during the winding procedure. The motor
- 12 -
- lOS5537
is connected to an encoder in the form of an electromcchanical
device that is used to provide an electronic output in the form
of a series of identical electrical impulses identifying minute
increments of rotation of the motor shaft. The output of the
encoder is fed into a memory bank of a computer that forms
part of the control system of the winding machine. Other types
of indexing structures can be used to setluentially index the
core 103 during the winding procedure.
Apparatus 100 has a first wire winding unit or mechanism
107 located on one side of armature 101 and a second wire winding
unit or mechanism 108 located on the opposite side of armature
101. The wire winding units 107 and 108 are identical in struc-
ture and operate to simultaneously wind coils of wirc onto the
core 103. The units 107 and 108 are mounted on table or platform
structures 109 and 110 with mounting flexure means indicated
generally at 111 and lllA. The mounting flexure means for unit
107 is identical with the mounting flexure means for the unit
108. The following description is directed to the mounting
flexure means 111. The mounting flexure means lllA that is
identical with mounting flexure means 111 has the same reference
numerals with the suffix A.
The mounting flexure means 111 is located above a gener-
ally horizontal support or frame 112. The flexure means com-
prises a first upright plate beam assembly 113 that connects
support 112 to the table 109. An anchor or bar 114 is secured
to the top o~ support 112. Support 112 can be provi~lcd with
slots or ~cyways to accommodatc ta]l~s or kcys on thc b;lr 114
and beam assembly 113. This structure can be the samc as shown
in Figure 2 as keyway 18B and keys 28~, 29~, 31B and 37B. A
plurality of bolts 116 secure the lower transverse scction of
beam assembly 113 to the anchor 114. A plurality of bolts 117

119. A plurality of bolts 122 secure the upper section of beam
assembly 118 to the end of table 109. Beam assemblies 113 and
118 can be single flat and flexible plate members or a plurality
of side-by-side flat and flexible plate members. For example,
beam assemblies can have the beam structure shown in Figure 3.
The mounting fiexure means 111 and lllA can be located in hori-
zontal positions with ends secured to vertical supports. The
plate beam assemblies can be vertical or horizontal. Alternat-
ively, the flexure means 111 and lllA can be supported from a
stationary overhead structure with the plate beam assemblies
extended downward to th-e housings or object support structures.
The wire winding unit 107 is identical with the wire
windin~ unit 108. The following description is limited to
unit 107. Parts of unit 108 that correspond to parts of unit
107 have identical reference numbers with the suffix A.
Wire winding unit 107 has an upright housing or block 123
secured to the inner end of table 109 with a plurality of bolts
124. The housing 123 has an annular opening accommodating an
annular ring-like member 126. Bearings 127 rotatably mount tlle
annular member 126 on the housing 123. A plate or disc 128 is
located within annular member 126. A guide or shroud 129 is
secured to plate 128. The shroud 129 llas arcuatc rccesscs for
accommodating an arcuate scgment of corc 123, as sl~own in
Figure 6. The annular member 126 has a longitudinal hole 131

An actuator 136, as a double acting cylinder having a
movable plunger 137, is mounted on top of the stand 134. The
plunger is movable into engagement with a pair of pivotally
mounted jaws 138. Jaws 138 are pivotally mounted on the guide
or shroud 129 and function to guide the wire over the end of
the core 103. Jaws 138 can be secured to the shrouds 129 and
129A and move with the shrouds to release positions so that the
armature 101 can be removed from the machine. Actuators 136
and 136A can be used to operate wire manufacturing mechanisms
(not shown) mounted on the shrouds. Alternatively, the actuators
136 and 136A can be removed when jaws 138 are secured to shrouds
129 and 129A.
A drive mechanism-, indicated generally at 139 in Fi~ures
- 6 and 7, operates to rotate the annular members 126 and 126A
in opposite directions to wind wire onto the core 103. Drive
mechanism 139 comprises an electric motor 141. Motor 141 is
mounted on a support 142 located adjacent the tables 109 and
lO9A. Upright stands 143 secure the support 142 to the frame
112. ~lotor 141 drives a pulley 144 carrying an endless belt
146. The belt 146 is trained about annular members 126 and 126A
and about an idler pulley 147. Idler pulley 147 is rotatably
mounted on an upright axle 148. A block 149 holds axle 148 in
an upright position. A spring 150 located in a groove in block
149 biases axle 148 in an outward direction to provide yieldable
tension on belt 146. The spring 150 allows axle 148 to move
toward units 107 and 108 when the units are spread apart. A
plurality of nut and bolt assemblies lSl secure block 149 to
the upper ends of stand 143. An encoder 152 is drivably coupled
to the drive shaft of motor 141. A support 153 secures encoder
152 to the motor 141. Encoder 152 is electrically coupled to
a control mechanism, such as a computer with its associated
memory. The drive mechanism 139 and the chucks or guide structures
- 15 -
1055537
129 and 129A are disclosed in U. S. Patent No. 3,980,242.
Referring to Figure 9, a control mechanism indicated
generally at 154 is operable to move the wire winding units
107 and 108 away from each other so that the armature 101 can
be removed from holder 104 after the winding procedure has been
completed. Units 107 and 108 are held in their spread positions
until a new unwound armature is placed in the holder 104 between
the chucks 129 and 129A. The control mechanism 154 is then
actuated to move wirc winding units 107 and 108 back to their
initial holding positions, as shown in Figure 9. Biasing means,
as springs, (not shown) can be used to assist the return of
units 107 and 108 to their initial positions. The plate beam
assemblies 113, 118, 113A and 118A function to accurately posi-
tion the units 107 and 108 in their initial positions and
support the units in the initial positions.
Control mechanism 154 has a first plate member 157 secured
with bolts 158 to the edge of table 109. A second plate member
159 is secured to the edge of table lO9A with bolts 161. The
members 157 and 159 extend in a downward direction and are
located adjaccnt a power applying assembly 162. The power
applying assembly 162 includes a member 163 pivotally mounted
on a support 164 with a pin 166. Support 164 is attached to
the support 112. A first link 167 is pivotally mounted to the
upper end of member 163 with a pin 168. The opposite end of
link 167 is attached with a pivot pin 169 to the lower portion
of member 157. A second link 171 is pivotally mounted to a
lower portion of member 163 with a pivot pin 172. The opposite
or outcr end of link 171 is connected with a pivot pin 173 to
a lower portion of membcr 159. A fluid motor, as an air cylin-
der, indicatcd gencrally at 174 is operable to rotatc member

163 and thereby move members 157 and 159 relative to eac~ other,
as shown by arrow 156. Fluid motor 174 has a double acting
cylindcr 176 attached to a bracket 177. Thc bracket 177 is
secured to support 112. A piston rod 178 extends from cylinder
176 and is connected with a pivot pin 179 to the lower end of
member 163. Other types of power applying assemblies can be
used to move the members 157 and 159 relative to each other to
move wire winding units 107 and 108 away from each other.
In use, the power applying assembly 162 is operated in
sequence with the winding operation of the machine. The power
applying assembly 162 is operable to rotate the member 163 and
thereby apply opposite outwardly directed forces to members 157
and 158. These forces flex the plate beam assemblies 113, 118,
113A and 118A, thereby moving the wire winding units 107 and
108 away from each other. When the power on the power applying
assembly 162 is released and reversed, the plate beam assemblies
113, 118 and 113A, 118A will reposition the units 107 and 108
back to their initial positions.
While there have been shown and described preferred embodi-
ments of the invention, it is understood that changes in the
use, size, materials and structures may be made by those skilled
in the art without departing from the invention.
