PIPE-HANGER.

SPEC'IFICATIOH forming part Of Letters Patent No. 680,609, dated August 13, 1901. Application filed October 12 1900. Serial No. 32,839. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH MAR UARDT, a citizen of the United States, and a resident of the borough of Manhattan, county of New York, city and State of New York, have invented certain new and useful Improvements in Pipe-Hangers, of which the following is a specification, reference being had to the accompanying drawings, forming part hereof.

This invention relates to hangers or supports such as are adapted for holding or supporting pipes or other objects. In the use of such hangers or supports various structures or parts of a building are encountered to which the hangers must be securedsuch, for example, as wooden beams, iron beams orsec tions, or arches of hollow or fireproof bricks; and one of the objects of my invention is to provide for suitably attaching the hanger to any of such structures or parts.

Other objects of my invention are to provide for a ready adjustment of the hanger after the hanger has been secured I or Whenever desired and to provide sufficient freedom of movement in the hanger to accommodate the movements of the pipes, due to expansion and contraction and other causes, and to accommodate irregularities and inac curacies in the location of the hanger.

My invention includes various improvements in hangers and parts thereof, all of which will now be particularly described with reference to the accompanying drawings, showing pipe-hangers embodying my invention.

Figure 1 isaside elevation of a pipe-hanger embodying my invention, showing a portion of a pipe supported thereby. Fig. 2 is an end elevation of the same, partly in central section. Fig. 3isa plan view of the pipe-holder. Fig. 4 is a perspective of the looped supporting part. Fig. 5 is a perspective of a modi fied form of looped supporting part. Fig. 6 is a sectional elevation showing the looped supporting part of the form shown in Fig. 5 and engaged with a hollow brick and also showing a modified form of suspending part. Fig. 7 is a sectional elevation of the parts of the construction shown in Fig. 6 and illustrates the manner of engaging the parts. Fig. 8 is a similar view showing the same parts secured to a wooden beam at the side thereof. Fig. 9 is a sectional elevation show ing another modified form of suspending part. Fig. 10 is a side elevation of the same.

The hanger inthe several modifications shown in the drawings comprises a supporting part and a suspending part constructed to interlock with each other, the supporting part having a loop with a slot therein and the suspending part having a head constructed to enter the slot and engage with the loop. The supporting part has a base and aslotted loop, and in the construction of hanger shown in Figs. 1, 2, 3, and at the supporting part is made up of two overlapping slotted pieces 5 5, provided at its base with means for engaging opposing ledges or shoulders, such means being shown as hooks 6 6, formed in the ends of such slotted pieces and catching over the edges of an iron beam 7,from which the hanger is shown as suspended. The overlapping portions of the two slotted pieces 5 5 form a loop traversed longitudinally by a slot, the slot beingconsiderably longer on one side of the center of the loop than on the other and closed at both ends. The rounded portion of the loop forms a part bearing at a distance from the base. The suspending part is provided with a head, shown as a T-head 8, of rounded cross-section and longitudinal section, which is constructed to,

enter the slot and engage with the loop of the supporting part, and to this end is narrower than the slot and longer than the width of the slot, so as to be capable of entering the slot when held parallel thereto on the side ofthe loop on which the slot is elongated toward the base, and after entrance into the slot of being turned through a right angle or quarter-revolution, so that'the head crosses the slot and engages with the loop on each side thereof. The manner of the engagement or interlocking of these parts will at the right with the long part of the slot downward and the head 10 having been turned ICO into a position substantially parallel to the slot and entered therein and having been moved horizontally and to the left to the po sition shown in Fig. 7. \Vith the parts as thus shown the head 10 may be turned through a right angle or quarter-revolution on a vertical axis and then moved to the rounded part or bearing of the loop, and then the supporting part will turn freely in this bearing upon the rounded side projections of the upper part of the head 10 as trunnions or pivots and may be turned thereupon either through a right angle or quarter-revolution to the position shown in Fig. 6, corresponding to the position shown in Figs. 1 and 2, or through a halfrevolution to the position shown in Fig. 8, or to any other desired position within the limits of its movement. With the two-piece supporting part shown in Figs. 1 to 5, inclusive, the T-head S by its engagement with the loop locks together the two pieces 5 5, composing the loop, thus effectually securing the supporting part in place, as well as interlocking the suspending part with the supporting part. The suspending part not only swings freely longitudinally by reason of the engagement with the loop of the rounded side project-ions of the T-head, but also has slight freedom of .lateral movement by reason of the longitudinal curvature of the T-head, and in Fig. 2 the loop parts of the pieces 5 5 are shown as transversely rounded to correspond with this longitudinal curvature of the T-head for the purpose of facilitating this lateral movement. These movements of the suspending part not only accommodate longitudinal movement in the supported pipes, but also lateral movements and variations of alinement thereof, as well as irregularities or inaccuracies in the location of the hangers. In the suspending part, as shown in Figs. 1 and 2, the T-head 8 has a socket 11 shown as secured thereto, this socket holding an adjustable. rod 12, which is shown as clamped therein by set-screws 13 13. The T-head 8 has an opening therethrough in line with the opening in the socket I1 to increase the extent of adjustment of the adjustable rod 12.

The pipe-holder is supported at the lower end of the adjustable rod 12 and comprises two arms 14 15, interlocking with each other at one end of each arm, as shown, the arm 14 having an open socket atits lower end which receives the rounded lower end of the arm 15, these two arms overlapping at the other end of each arm, as shown, the upper end of the arm 15 extending over the upper end of the arm 14. A key is provided for locking the overlapping ends together, such key being shown as aflanged sleeve l6,fitting loosely on the adjustable rod 12 and resting upon a head 17 thereon and passing through perforations in the overlapping ends of the arms 14 15. The walls of the perforations in the overlapping upper ends of the arms 14 15 are provided with slots 18 19, respectively, shown as diametrically opposite, and a projection 20 is provided upon the key or sleeve16, this projection being shaped to enter and pass through the slots 18 and 19 of the overlapping arms.

In assembling the various pieces of the holder the key 16 is first slipped over the adjustable rod 12, and then the arms 14 and 15 are successively slipped over the key 16, the projection 20 passing through the slot 18 of the arm 14 and the key being then turned through half a revolution and then passing through the slot 19 of the arm 15. To close and lock the parts of the holder over a pipe to be supported, such as the pipe 21, the arms may be closed over the pipe, the upper end of the arm 15 being originally above and clear of the key 16, so that it may be readily opened sufficiently to take in the pipe, and the upper end of the arm 15 being then moved downward upon the key into contact with the upper end of the arm 14 and the lower end of the arm 15 being inserted in the socket at the lower end of the arm 14. The key 16 may then be turned so that the projection 20 is out of line with the slot 19, as to the position shown, and will lock the arms together.

A modified construction of the suspending part of the hanger which may be employed for supporting large ventilating pipes is partly shown in Figs. 9 and 10, in which a socket 22 of substantially rectangular form is employed, having a rectangular opening to receive a flat metal rod, bar, or strip 23, the lower end of which may be suitably secured to the pipe to be supported. As the rectangular opening does not extend up into the T-head 8, the socket 22 is longer than the socket 11 to provide a considerable range of adjustment of the flat rod 23. The flat rod is adj ustably held by set-screws 13.

Another modified form of suspending part is shown in Figs. 6, 7, and 8, in which the adjustable rod 24 is threaded directly into the T-head 10. The rod 24 may support a pipe-holder, such as is shown in Figs. 1, 2, and 3, or may be provided with any suitable means for engaging or supporting the pipe or other device to besupported. Other modified forms of suspending part may be employedas, for example, the key 16 (shown in Figs. 1, 2, and 3) may be replaced by a screwthreaded socket to engage different forms of holders.

The modified construction of supporting part shown in Figs. 5 to 8, inclusive, and heretofore described as made of a single piece of metal 9- is adapted to be secured to the vertical face of a wooden beam 25, as shown in Fig. 8, by screws 26 passing through the base of the supporting part, as shown, and may be secured to any surface or wall or ceilingto which the supporting part may be held by screws, nails, or other fastening devices. It is also adapted for engaging with a surface of fireproof or hollow bricks. For this purpose an opening is made in one of the bricks,

IIO

as the opening 27 in the brick 28, (see Fig. 6,) sufticientlyl'arge to admit the supporting part 9 when turned with its fiat ends or base substantially vertical or into the position shown in Fig. 8, and the supporting part after having been interlocked with the suspending part is turned to this position and pushed upward through the opening 27 and is then turned so that its base or flat ends shall be substantially horizontal and is lowered until these flat ends engage with the lower inner surface of the brick, as shown in Fig. 8. During these manipulations the adjustable screw-rod 24 should be screwed down, so as not to protrude above the T-head 10, as shown in Figs. 7 and 8; but with the parts in engaged position the screw -rod 21L may be screwed upwardly as far as the hollow in the brick 28 will permit, and thus a considerable range of adjustment is provided. It will be observed that when the screw-rod 2i protrudes above the T-head 10 it will effectually prevent dislodgment of the supporting part. It will also be observed that when the supporting part is secured to the side of a beam, as shown in Fig. 8, there is a clear space above the T-head, permitting the screw-rod 24: to be screwed upwardly to protrude above the T-head, as desired for the adjustment of the length of the suspending part of the hanger.

It is evident that various modifications other than those above described may be made in the construction of the several parts of my hanger.
