PIPE HUNGER
Background ox the Invention
(1) Technical Field
-
This invention relates to pipe hangers of the type normally
employed to suspend pipes from overhead supports in spaced
relation thereto.
(I Description of the Prior Art:
Prior structures of this type have generally taken the form
of a band arranged in an oval shape with its ends aperture and
arranged in superimposed position over a flanged cylindrical
coupling which in turn is internally threaded for threaded
engagement with a supporting rod and as illustrated in U.S.
Patent 2,996,274.
Proposals have been made to alter the usual pipe hanger
constructions by clampingly engaging the pipe carrying portion
of the pipe hanger on a supporting rod or on a fastener carried
by a supporting rod and such constructions may be seen in U.S.
Patents 476,227, 1,392,810, 1,870,651 J 1,924,353, 3,493,206, and
4,306,696.
Swiss Patent No. 592,837 discloses a strap which can be
positioned around a pipe and its ends arranged in oppositely
disposed relation on the sides of the threaded rod with a tubular
member positioned there over and held in desired position by a
threaded nut engaging the threaded rod.
The present invention differs from the prior art in pro-
voiding a simple structure which is less expensive -to manufacture
,, .,
Sue
and is easier to install than the prior art devices and part-
ocularly in the use of an aperture spring clip positioned over
over the end configurations of the band in the areas where they
engage the threaded rod to form a locking device which may be
quickly and easily installed and/or removed.
Summary of the Invention
An improved pipe hanger is disclosed which is formed of only
two pieces which are engagable with a threaded support rod to
form a complete pipe hanger. The pieces comprise an elongated
10 band such as formed of sheet metal or metal strapping with end
configurations defining half circular shapes and internally
threaded or knurled and arranged to be positioned against the
outer opposite sides of a -threaded support rod and wedged there-
against by the application of an aperture spring clip to lock
-the assembly in desired pipe supporting position.

Description of the Preferred Embodiment
28 By referring now to Figures 1 and 2 of the drawings, it
will be seen that a supporting rod 10 having threaded end sections
I\
~æ~
11 and 12 respectively thereon is illustrated and those
skilled in the art will observe that such supporting rods are
common in the pipe hanger art and are usually affixed at their
... ...
upper ends to an overhead support such as a beam or the like
usually by way of a clamp, not shown. An elongated sheet metal
strap 13 comprises the portion of the hanger which is positioned
around a pipe P to be suspended thereby. The elongated strap
13 has its end portions 14 and 15 respectively, shaped in sub-
staunchly half circular arcuate configurations with represent-
lions of thread patterns 16 and 17 or the like formed on thornier opposed surfaces. An aperture spring clip 18 consists
of a section of an elongated resilient metal member bent into
a V-shape with arms 19 and 20. Apertures 21 and 22 in the arms
19 and 20 are arranged to register with one another when the
arms 19 and 20 are moved against the resiliency of the metal
member to a first position adjacent one another. In such first
position, the aperture spring clip 18 may be moved from
a position where the supporting rod 10 is positioned through
the apertures 21 and 22 in the spring clip 18 downwardly and
20 over the end portions 14 and 15 of the elongated strap 13
when they are engaged on the lower portion 12 of the supporting
rod 10 as best seen in Figure 2 of the drawings. Releasing the
arms 19 and 20 of the aperture spring clip 18 causes the same
to move to a second position as best seen in Figures 2 and 4
of the drawings where the apertures 21 and 22 move out of
registry and sharply frictionally engage the outer surfaces of
the end portions 14 and 15 of the elongated strap 13 of the
I pipe hanger. The frictional engagement of the metal defining
~2~4;2~
the edges of the apertures 21 and 22 is substantially improved
by their angular relationship with respect to the outer surfaces
of the end portions 14 and 15 of the elongated strap 13 as
the same bite into the outer surfaces of the end portions 14
and 15 and lock the aperture spring clip 18 securely in position
as shown in Figure 2 of the drawings where it continuously exerts
tension holding the end portions 14 and 15 of the elongated strap
13 tightly against the threaded lower portion 12 of the support-
in rod 10 and thereby conveniently and satisfactorily supporting
the pipe P there below.
In Figure 1 of the drawings, the aperture spring clip 18
is shown in substantially its first position, the arms 19
and 20 having been moved toward one another to bring the
apertures 21 and 22 into substantial vertical registry so that
when the elongated strap 13 is positioned about the pipe P
and the ends 14 and 15 of the strap moved into engagement with
the opposite sides of the lower threaded end portion 12 of the
- supporting rod 10, the aperture spring clip 18 may then be
moved downwardly over the ends 14 and 15 and released whereupon
it will assume its locking position as generally indicated in
Figure 2 of the drawings.
In Figure 3 of the drawings, the aperture spring clip 18
is shown in substantially its first position with the apertures
21 and 22 in substantial vertical registry as necessary in the
installation or removal of the clip from the assembly and in
Figure 4 ox the drawings, the top plan view of the aperture
spring clip 18 shows the arms 19 and 20 in their second position
I where the arms 19 and 20 have moved away from one another and
owe
the apertures 21 and 22 are out of registry and in the locking
position shown in Figure 2 of the drawings.
It will thus be seen that a simple, inexpensive, and highly
practical pipe hanger has been disclosed which is easily formed
of inexpensive materials very easily handled in the field in
installing pipes and the like and that such installation is
quick and easy with the two movable parts of the pipe hanger
becoming locked together upon the final positioning of the two
parts of the pipe hanger, all as herein before set forth.
Although but one embodiment of the present invention
has been illustrated and described, it will be apparent to
those skilled in the art that various changes and modifications
may be made therein without departing from the spirit of the
invention. Having thus described my invention, what I claim is:
