Original application filed January 20, 1921, Serial No. 438,682. Divided and this application filed June 1 "0 all whom it may concern:

Be it known that 1, .lniuus T. BARRY. a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented a new and useful Improvement in Pipe 01' Conduit Hangers, of which the following is a specification.

This invention relates to. pipe and conduit hangers.

This invention and its embodiments later described herein in detail and claimed is designed as an improvement upon and development of the principal features of the invention as set forth in my prior application Serial No. 138,682; and to this end I contemplate the embodiment of the same objects and advantages set forth in the prior application, together with additional features of construction as hereinafter pointed out.

In keeping with the foregoing in the pres.- ent instance I provide one form. of the invention wherein relatively large conduits may be supported longitudinally of a flanged girder; another form wherein a con duit may be supported transversely of the girder; and still another form serving for the support of a plurality of parallel conduits.

Other objects and advantagesof this in vention will appear from the following detail description and the claims, taken with the accompanying drawings, in which-- Figure 1 is an elevational view of a hanger constructed in accordance with my invention, and applied to an I beam;

Figure 2 is a perspective view of the hanger;

Figure '3' discloses side and front elevational views of a modified form of the invention;

Figure 4' discloses similar views of another modified form. of the invention;

Figure 5 discloses end and side views of the further modified form for supporting a plurality of conduits.

Referring more particularly to the drawings, and first to that form shown in Figures 1 and 2, an I-loeam 1 is shown having the usual flanges 2, a conduit 3 lying beneath the flanged beam and longitudinally thereof.

The hanger comprises a flat strip possessing slight resiliency bent near one end to form a tongue 5 overlying and in direct con- Serial No. 478,039.

tact with the upper surface of one of the flanges, the shank or vertical portion 6 lying across the edge of the flange and formed with a curved seat 7 below the flange, this seat receiving the conduit The under surface of the tongue 5 is preferably serrated at S to insure its frictional engagement with the flange.

lhe shank 6 is provided. with a longitudinal slot 9 enlarged. near the tongue 5 to form shoulders 1010. A key member or wedge 11 serrated on both sides and tapered at one end, is insertible into the enlarged portion of the slot and abuts the shoulders 10, the wedge, when the device is assembled. extending between the under surface of the flange and the conduit, the abutment of the wedge on the shoulders 10 serving to maintain the tongue 5 in snug frictional engagement with the flange, this wedge also frictionally holding the pipe against displacement due to vibration.

Referring now to Figure 3, an angle-bar A is shown, to which the conduit 12 is longitudinally supported, this bar being fully the equivalent of an I-beam. The hanger preferably embodies a fiat strip 13 possessing some resiliency and provided at one end with a tongue 14, adapted to overlie the horizontal flange 15 of the bar, and provided at the other end with a curved seat 16 to receive and support a conduit 12, of relatively large diameter.

The shank 18 of the hanger lies across the edge of the flange 1.5 and is provided with an opening 19 near the tongue 14 and the upper end of the opening disposed above the upper surface of the flange to receive a looking member. which latter preferably takes the form of a flat bar 20 serrated on both sides. hen inserted the bar 20 is in snug contact with the upper surface of the flange and the end of the tongue 14; iin iiinges upon the upper surface of the serrated bar. The opening 19 ,is formed preferably by punching the shank, the metal struck therefrom forming a lug 21 lyingbelow the flange of the angle-bar. Thus the abutment of the lug 21 against the angle-bar flange, and the impinging of the tongue 14- on the serrated bar cooperate to rigidly connect the hanger to the angle-bar. and thus support the pipe or conduit against accidental displacement.

Referring now to the form of the invention shown in Figure i, an angle-bar 22 is shown having a. horizontal flange, it being desired, in this instance, to support a conduit 23 transversely to the longitudinal axis of the beam. To this end the hanger comprises a flat somewhat resilient strip formed with a shank 2 L, tongue 25 overlying the flange of the angle bar, and a seat 26 having its axis transverse to that of the shank. Near the upper end of the shank and above the upper surface of the angle-bar flange an opening 27 is punched in the shank, a locking bar 28, serrated on both sides, entering said opening and lying between the tongue and the adjacent surface of the flange. As shown, the conduit 23 abuts the under surface of the flange, and this, together with the impinging of the tongue upon the looking bar 28, serves toseeurely maintain the hanger against displacement.

It will, of course, be obvious that where necessary or desired, the form shown in Figurel or Figure 3 may be used in a pipe assembly, and where it becomes necessary to support the pipe or conduit transversely of a beam the form shown in Figure 4: may be employed.

In some instances it is necessary or desirable to support a plu 'ality of conduits on a single beam, or upon two contiguous beams and to this end the form of the invention shown in Figure 5 is designed. In this instance a pair of hangers are provided comprising flat strips of semi-resilient metal having shanks 30-30 disposed vertically of the flanges 31 of the beam 32, said shanks having tongues 33-33 overlying the flanges 31, the lower ends of the shanks having complemental pairs of marginal notches 34 34l for reception of complemental tongues 35-35 formed on the opposite ends of a tie bar 36. A plurality of conduits 3737 are sup ported by the tie bar 36, and abut the under surface of the beam flange. The shanks 30 are provided each with an opening 38, located above the upper surface of the beam flanges for reception each of a wedge 39, the wedge passing between the adjacent tongue and surface of the beam flange.

It will be apparent that when the hangers of the last described form of the invention are assembled the conduits and the tie bar arranged as shown, and the wedges inserted, the whole structure will be rigidly mounted upon the beam.

\Vhile I have described my invention as embodying certain details of construction, it will of course, be readily understoodthat I contemplate minor changes in the separate parts within the spirit of the invention, and scope of the claims.
