CALVING PANEL

Abrégé anglais

A device for capturing and restraining a cow for the
purpose of examination and/or assisting with the delivery
and subsequent suckling of a calf and/or performing such
medical procedures as may be required is constructed of
steel and comprises a headgate, a side panel and a
detachable back gate. The headgate has sleeves that attach
with pins to mounting plates or a maternity pen on the right
side and is welded at a right angle on the left side to the
side panel. The top section of the side panel comprises
removable vertical bars to facilitate access to perform a
cesarean section. At the lower rear of the side panel is a
section which can be removed to permit access to the cow's
udder for a calf to suckle. Removal of this section also
allows greater access for a calf puller if necessary.
Attached to sleeves on the back of the side panel is a
detachable back gate which pivots to be closed and fastened
behind the cow or lifts upwards to be removed entirely to
provide access to the rear of the cow.

Description

2113235
CALVING P~NEL
The present invention relates to a device to promote
the safe handling of a cow for a variety of procedures,
specifically to assist in delivery and suckling of a calf.
The types of devices available for the purpose of
examining a cow and assisting in delivery are contained
within a maternity pen as a fixed stall. As this stall is
permanently located within the maternity pen, it limits the
remaining space in the maternity pen. Some difficulty may
also arise in maneuvering an unwilliny cow into one specific
stall. Not all livestock facilities provide for the space
required to set up a complete maternity pen.
It is desirable to have a device such as a calving
panel which is more easily operable by one person, in that
it allows a cow to be rounded up from within a larger area.
It is further desirable for such a device to take up less
space and to be more portable. The present invention
relates to a device for more easily restraining and
examining and/or assisting a cow in a limited space. This
device may be mounted in a building or maternity pen and may
be transferred from one location to another by removing and
replacing two pins.
The present invention consists of a headgate, a side
panel and a removable bacX gate. In one aspect the device
comprises a headgate consisting of a frame, two vertical
uprights and a latch. The headgate has sleeves that attach
with pins to mounting plate~ or a maternity pen on the right
side.
-- 1 --

` 2~1323~
In another aspect, the headgate is welded at a right
~ angle on the left side to a side panel with removable
vertical bars which are spaced to facilitate access to
perform a cesarean section. In this aspect the side panel
also comprises, at the lower rear, a section which is
secured to the frame by a pin. This pin is easily removed
to allow the section to be removed to permit access to a
cow's udder for a calf to suckle. Removal of this lower
rear section also allows greater access to the rear of the
cow and provides more maneuverability for a calf puller if
necessary.
In a further embodiment of the invention, at the back
of the side panel is a detachable back gate which pivots in
sleeves to be closed and fastened behind the cow or which
can be lifted upwards and removed entirely to provide access
to the rear of the cow.
The invention, as exemplified by a preferred
embodiment, is described with reference to the drawings in
which:
Figure 1 is a perspective view of an embodiment of a
calving panel of the invention; and
Figure 2 is an exploded view of the calving panel shown
in Figure 1.
Referring to the drawings, the embodiment of the
invention shown, a calving panel 10 comprises a headgate
12. The headgate comprises a frame 14, two vertical
uprights 16, 18 and a latch 20. One vertical upright 16 is
fixed at the top and bottom; the second vertical upright 18
i8 inserted into one of several holes 22 in the 'op of the
bottom section of the frame, the top of the second vertical

211~2~5
upright being allowed to slide from side to side in a
~ horizontal slot 24 in the top section of the frame. The
latch locks the second vertical upright at specific
locations 26 along the top section of the frame when pulled
by a rope attached above the latch 28. The headgate also
has a vertical notch 30 in the bottom of the top section of
the frame located near the end of travel of the second
vertical upright which allows the second vertical upright to
be manually slid along the horizontal slot to the vertical
notch, lifted upward, and moved to a different hole at the
bottom for adjustment or moved out of the way to free the
cow. Sleeves 32 are affixed to the right side of the
headgate frame near the top and bottom. The calving panel
is mounted to a wall or maternity pen by aligning these
sleeves with sleeves 34 on the mounting plates 36 and
inserting pins 38 thus creating a pivoting hinge system.
The left side of the headgate frame is welded to the
front of the frame 40 of the side panel 42 at a right
angle. The side panel also comprises multiple removable
vertical bars 44, a removable nursing section 46, a chain 48
and a notched latch 50. The multiple removable vertical bars are
positioned in holes 52 located in the frame in such a way
that each removable vertical bar may be manually raised
upward and removed for casarean sections. The nursing
section may be removed by removing a hairpin 54 and a pin 56
to provide access to the cow's udder for a nursing calf,
- hand milking or a calf puller. A chain and a notched
latch are fixed to the rear of the frame of the side
panel to secure the back of the calving panel once the cow
has been captured.
The back gate 58 is attached to the back of the side

r- - .
~- 211323~
panel by inserting the bottoms of the rods 60 on the gate
into the tops of the sleeves 62 on the rear of the side
panel frame.
A feature of this invention is that the entire unit
pivots on a hinge system affixed to the right side of the
headgate allowing it to swing out when capturing the cow,
and to swing into a 90 degree corner of a building or
maternity pen when not in use. This device can be operated
by one person as it pivots on this hinge system to close in
around a cow simultaneously as the headgàte is latched by a
rope.
