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 Drawings Figure 1 is an exploded front elevation Al view with parts broken away illustrating a pipe, a pipe hanger and a supporting rod;
Figure 2 is an enlarged cross section of a portion of an assembly of the pipe hanger seen in Figure 1 with parts broken away;
Figure 3 is a perspective view of the spring clip seen in Figures 1 and 2; and Figure 4 is a top plan view of the spring clip of Figure 3.
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:

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.

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 Drawings Figure 1 is an exploded front elevation Al view with parts broken away illustrating a pipe, a pipe hanger and a supporting rod;
Figure 2 is an enlarged cross section of a portion of an assembly of the pipe hanger seen in Figure 1 with parts broken away;
Figure 3 is a perspective view of the spring clip seen in Figures 1 and 2; and Figure 4 is a top plan view of the spring clip of Figure 3.
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\

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:
