10 Claims.

The present invention relates to a pipe hanger system comprising a smallnumber of-simple elements of universal adaptability and associa'bility' in a variety of ways, .by means of which a large Further objects of the present invention will appear from the following description with referenceto the accompanying drawings.

The above mentioned elements from which the pipe support may be assembled comprise a hanger I proper having two arms with flanged ends for receiving a locking bolt and a top portion of novel design which makes it capable of engagement with a hanger housing in any desired position and of easy sliding movement thereon. The hanger housing, which is the second of the above mentioned elements, is channel-shaped; it is proof which the casing is fastened to the supporting structure of the pipe hanger. A third, element to be used in the combination is a c shaped clamp such as is commonly used with I-beams;

Fig. 14 shows a clamp and a hanger-rod screwed thereto and fastened to an angle-iron;

Figs. 15 and 16 show a retaining clip as used in several applications, in plan and elevation respectively. 1

Fig. 17 is a perspective view, with parts of the housing broken away, showing said housing and three hangers attached thereto;

Fig. 18 is another application of one housing and three pipe hangers at different levels and angles with respect to the' housing;

Fig. 19 shows a housing carrying three pipe hangers and being clamped to an I-beam by means of two C-clainps;

Fig. 20 is another application of a housing with three hangers, in which the hangers are suspended on rods at different angles, the housing being clamped to an angle-iron; and

Figs. 21 to 24 show some more combinations for the arrangement of a plurality of pipes of different, sizes, disposed, at different levels and angles with respect to the supporting structure.

The elements for building up the various structural embodiments of the present invention are shown in Figs. 1 to 6, 11 and 12. The pipe hanger proper, generally indicated by'5, comprises a top portion 6 which has a web I with a central opening 9 and rectangularly bent side portions 8. The latter have four slots l formed therein which serve for-engagement with the housing I2. The hanger has two-curved arms l3 for gripping a pipe P. The lower ends ofsaid arms [3 terminate in flanges H which receive .a threaded bolt ii that serves for drawing the end portions together when a pipe is in position, in which it may be locked by nut l1.

tive to the circumference of the pipe to be suspended are such that the pipe is forced into contact with the housing i2 when the bolt and nut l--ll aretightened.

The housing l2 has a web portion 18, depend- It will be readilyunderstood that a similar construction could be used -for layinga plurality of pipes parallel to each other in a horizontal plane. i

In the attachments shown in Figs. '7 to 9 the pipe lines are suspended or supported in close proximity of the building structure. This is convenient for purposes of electrical installations.

In other cases, such as the installation of steam pipes, it is common usage to dispose the pipes at a certain distance of the supporting structure to allow for expansion by heat or for the purpose my invention, 1

The dimensions of the curved arms I3 and the shape thereof rela ing side portions I9 and inwardly bent flanges 20, which serve for engagement with slots iii of the hanger. The dimensions of the slots 1 0 rel- .ative to the dimensions of the. flanges 20, are such that the hanger proper can be slid readily along. the flanges and to permit the pipe clamping action above referred to. The web 18 has, in the example shown in the drawings, three anchor slots; when onebeam clamp or ceiling anchor 'is used it is fastened through the center slot 2!, when two clamps or coiling anchors are e used they are fastened through slots 22. At the 7 ends the housing is equipped with'cotter pins 23,

which are used for looking a plurality of pipes in thelhousing and will prevent their sliding out of the'h'ousing at a time when they are moved,

for instance, for rearrangement. I r The four slots ID are made-loosely to fit'the flanges 20 so that the hanger may easily be moved to any desired point in the housing. Locking and unlocking of a pipe in the hanger is easily accomplished by tightening or loosening bolt l5. As best shown in Fig. 6, upon tightening of bolt l5 .The C-clamp shown in 11 and 12 has the two clamping arms with enlarged ends 24 bored at 26, each bore being internally threaded.-

One of these threaded bores receives a bolt 21 which serves for clamping ahanger to an'I-beam or similar element of construction. The other threaded bore serves for receiving an element which is to be brought into clamping engagement with said structural element. shown in Fig. 13 that. the lower bore 26 receives a bolt 28 for connecting a hanger to said clamp and in Fig. 14 it is illustrated as receiving a hanger rod 29.

pipe P is pressed against the flanges 20 and is j immobilized thereby, independently of whether ,the housing be disposed in horizontal or vertical position.

pipe to a concrete ceiling C. Inthis case the housing l2 may be omittedand a single bolt b may be used for fastening the hanger by being passed through hole a; This attachment is not only very'simple, it also makes it possible to run Fig. 9 shows the attachment oftwo pipes in a vertical plane by means of a housing. The numberof pipes could be varied as desired. The

advantage of this construction is easy rearrangement within the vertical plane in case another I spacing of the pipes should become desirable.

In some cases where there is intense vibration it is desirable to use a retaining clip 30 as shown in Figs. 15' and 16 for securely fastening to a beam I or angle irona. One end of clip 30 is cut out at 33 to form two prongs 34, which are slipped past the thickened end 24. of the clamp and bent down as shown in Figs. 13 and fastened to an angle iron a by means of a clamp without interposed retaining clip, the position of the hanger and angle being inverted as compared to Fig. 14.

As mentioned before the pipe hanger according to my invention is very well adapted for attaching multiple lines of pipe tohorizontal or vertical supporting-structures. Figs. 17 to 20 inclusive, illustrate examples in which three pipe lines may be fastened by different ways of attachment to concrete ceiling or to" horizontal beams.

In Fig. 17 the housing I2 may be attached to an overhead support by bolt b. The housing carries three hangers in engagement with flanges 20. For inserting pipes, bolts l5 are unscrewed and as soon as the pipes are in proper position' the bolts are tightened for locking.

Due to the strength of the housing, which is made of heavy gauge steel, it is possible to make many installations while using a single anchor bolt as shown inFig. 17. In this case the housing can be adjusted on the ceiling so that the pipes can be run-in any desired direction.

If it is desired to hang the pipes at differentlevels an arrangement as shown in Fig. 18 may be applied. In this case nuts, 36 are provided of a size that will allowthem to remain in sliding engagement with flanges 20 of the housing l2. The nuts are connected with the hangers by means 01' rods 38 and which may be of Thus it is shown at 42.

- various desired lengths. When the hangers are thus suspended by nuts and rods the pipes may I be run in any direction, regardless of the fact whether one anchor bolt or' two anchor bolts are used for attaching the housing to the building structure. The rod-,and-nut suspension of the hangers may be combined with the direct channel engagement of some of .the hangers, as

likewise shown in Fig. 18 of the right-hand side of the flgure.

Figs. 19 and 20 show how multiple lines of pipe may be attached to an I-beam. This is a further development of the arrangement shown in nuts 36 by means of rods 38 of various lengths,

which arrangement allows the running of pipes in different directions and at any desired level.

Fig. 21 shows another embodiment of the invention in which one set of hangers is arranged on top of a housing I2 and another set of han ers at the bottom thereof. In this case the attachment of the top row of hangers is accomplished by tapping the web l8 of the housin and screwing the hangers thereto as at 40. Hangers of different sizes may be used if desired. At the bottom of housing I! the flanges may be used for suspending thereon hangers 5, by means of the interengaging slots it), as shown at II, or by rod-and-nut connection, as

Two rods 43 are, moreover, provided for suspending the housing at any desired level.

A similar arrangement of different sets of pipe hangers is illustrated in Fig. 22, the difference being that two housings are used in end to end position for the attachment of all the pipe hangers.

The unusual flexibility of arrangement for a plurality'of pipe lines of which the construction is capable is exemplified by Figs. 23 and 24.

Fig. 23 shows an arrangement of three housings, one of which, lZa, is disposed horizontally.

While the other two, lZb, are disposed at right anglesthereto. This arrangement of housings is effected by means of angles 45 to which the housings are secured by bolts at 46. The vertical- 1y disposed housings 12b each carry a plurality of hangers 5 for the support of sets of parallel pipe lines. to support a set of pipe hangers at the under side and a single hanger of larger size on top.

Evidently this arrangement is capable of a number of further variations which will be understood by any person skilled in the art without further explanation.

' the upper housing by means of two O-clamps.

The lower housing is riveted to the upper one and carries on its under side a desired number of hangers which will support pipes running in a direction at right angles to the direction of the upper pipe P.

The horizontal housing'l2a is shown 'Figs. 10, 13 and 14. When it is desired to at- In this case, too, many other variations will readily present themselves to anyone skilled in the art, particularly in combination with the examples described and shown in several of the otherflgures.

To contractors, plumbers, steam fitters, industrial electricians and millwrights itwillbe apparent that I have discloseda pipe hanging system comprising a few elements of simple, sturdy construction and the use of which will eliminate a great deal of labor in drilling, sawin and flt- .ting ofhanger straps and similar manual iron working while on the installation job. The parts are interchangeable and adaptable to ready securement to a variety of mill building constructions and inspection and repair or replacement of any one of a number of pipe lines arranged in clusters can be accomplished in an expeditious manner.

To those skilled in the art it will be apparent that other combinations and assemblies of the interfltting and interchanging of parts in accordance with the dictates of the requirements of the particular installation can be effected readily. In some instances cluster assembl es, such as indicated in Figs. 18, 20, 22, 23 and 24 can be brought together in a loose fashion with the various slidable elements retained in place by the cottcrpins and at the shop before shipment to the place of installation. It will also be apparent to those skilled in the art that the degree of the clamping action of the hanger member, proper upon a steam line or line subject to longitudinal expansion and contraction under varying thermal conditions will lie within the judgment of the me chanic making the installation.

Other modes'of applying the principle of my invention may be employed instead of the one explained, change being made as regards the structure herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention: r
