Hanger for pipes, &c.

Application filed April 10,1905. Serial No. 254,814,

To all whom it may concern:

. Be it known that I, William Houghton, a citizen of the United States, residing at Bath, in the county of Sagadahoc and State of Maine, 5 have invented certaib newand useful Improvements in Hangers for Pipes, &c., of which the following is a-specification.

The object of my invention is to provide a hanger for supporting pipes, electric conduits, io &c., from beams, joists, or the like, but which is especially adapted for use on shipboard, where the apartments, are seldom ceiled and where it is not feasible nor advisable todisturb the integrity of the beams, which are usually 15 made of steel, by puncturing them for boltholes or for passage-ways for pipes. It is desirable that such hangers shall be easily and quickly applied to a pipe and its supportingbeam at any desired point and easily removed.

It is also desirable that the hanger should consist oi as few parts as possible and should firmly engage the beam without putting undue strain on the pipe, cable, or other part supported.

Briefly stated, my improved hanger comprises arms having flanges adapted to engage the rib of a beam and to which a support for a pipe or cable is connected, a clamping-block extending between the arms and having a. flange at one end to engage the beam and a wedge or clamping device engaging the arms, and a flange on .the clamping-block which serves to draw the flanges of the yoke and block firmly against the beam.

My improvements thus briefly outlined may be embodied in many specific forms of pipe and cable hangers;

In the accompanying drawings I haveshown several of the improved hangers which I have 4° devised.

Figure 1 is a side elevation of one form of my improved hanger in operative position on a pipe and beam, the supporting-beam being shown in section. Fig. 2 shows a front elevation of the same, the pipe being shown in transverse section. Fig. 3 shoiys a front elevation of a modified form of hanger applied to a beam. Fig. 4 is a perspective view of the same. Fig. 5 is a view similar to Fig. 1, showing the hanger designed for use with a beam having a curved rib on its lower edge. Fig. 6 is a view similar to Fig. 1, showing a modification in which the pipe-support is separable from the other part of the hanger. Fig. 7 is a perspective view of the pipe-supNo. 802,103.

Fig. 10 is a perspective 6o view of the form of pipe-support shown in । Figs. 8 and 9. Fig. 11 shows a further modification in which the pipe-support is adapted, to sustain a plurality of pipes and the support is connected with two clamping members. Fig. 12 is a perspective view illustrating the shape of the pipe-support shown in Fig. 11.

In Figs. 1 and 2 the arms A A of the hanger are prolonged downwardly and formed in one piece with the pipe-support B, the arms A and support B constituting a U-shaped yoke, through which the pipe P extends.. Both the arms and yoke are preferably made of wroughtiron. Each of the arms A is provided at its upper end with a flange ®, adapted to fit over and snugly engage the rib c of the beam C. -Each arm A is also formed with a laterallyprojecting flange extending in an opposite direction from that in which the flange a extends. The flanges a are preferably so shaped as to engage only a portion of the entire contour of .the rib c. Hence the same hanger may be used, with different sizes of beams of the same general type. A clamping-block D, as shown in Figs. 1 and 2, may be slightly curved 85 to fit the upper surface of. the pipe. It is formed -with a flange d, adapted to engage the beam C on that side opposite the rib c, and it is also formed with a flange d' at its opposite end. The clamping-block extends over the pipe, beneath the beam, and between the arms A A. E indicates a wedge or key arranged between the flange d' and the arms A and beneath the flanges a'. When this wedge is driven home, it forces the arms A and the flange d against the beam, thus holding the beam with a clamping action. The form of the key or wedge E is more clearly illustrated in Fig. 4. The same wedge or key is used in the various modifications illustrated. There is not much danger of the wedge slipping; but to avoid any possibility of its doing so I,may use a suitable locking device, such as a screw F,“’attached to one of the flanges a' and having an enlarged head adapted to overlap the ioe larger end of the wedge and prevent it from .- moving outward. The relation of this locking device with the other parts is indicated in Fig. 1 and is also more, clearly shown in the perspective view Fig. 4.. The locking deyice no ⁶5

In Fig. 3 the construction is substantially £5 the same as in Figs. 1 and 2. served that the arms A A and the parts at the upper portion of the hanger correspond in all < respects with what is shown in Fig. 1. Ih ’ pine-support B is, however, prolonged downwardly? being U-shaped and attached to a cross-piece G, in turn connected with the arms A. In all other respects the hanger shown in Fins. 3 and 4 is the same as that shown in , Fins. 1 and 2. By the modification shown in Fig. 3 1 am enabled to suspend a pipe or cable at any desired distance below the beam, and the clamping-block does not necessarily come in contact with the pipe of cable.

In Fig 5 the construction is precisely the same as in Fig. 1, except thatthe form of the rib on the beam is slightly different a,nd the . shape of the flanges «is changed to accommodate the shape of the rib. ; .

In Fig. 6 the arms a terminate a snort distance below the clamping-block D, the pipesupport in this instance consisting of a ring H, having ^vertical arm H formed with a horizontal· extension h and a downwardly-extending flange h'. This pipe-support is connected with the hanger clamping members by causing the extension h to rest on the cross-piece /connecting the arms A, in the manner illustrated in Fig. 7. .

In Figs. 8 and 9 the clamping members are similar to that shown in Figs. 6 and 7, but the hanger B is of the form shown in Fig. 10, being made of wrought-iron bar twisted to the form illustrated. The pipe-support is in this instance U-shaped, having two lateral extensions M, each of which is adapted to engage the cross - piece d‘ connecting the arms A. This form of hanger is preferable where the pipe or cable is of large diameter, as the pipe4o support may be made of any desired width may hold the pipe any desired distance below the beam, and yet may be properly supported at its, ends. ‘ , „„„

In Figs. 11 and 12 the clamping membei s are similar to those shown in Figs. 8 and 9. The pipe-support, however, in this instance consists of a plate N, having a series of perforations n, each adapted to receive a pipe or cable. At each end the plate is formed with a laterally-extending arm N , adapted to rest on the cross-piece a* of the hanger. .

It will be observed that the upper part ot the hanger in all cases is substantially the same, while the lower pairt is modified in various ways.
