July 15, 1958 J. H. MAILANDER TUBING HANGER Filed NOV. 4, 1954 INVENTOR United States Patent TUBING HANGER John H. Mailander, Alexandria, Va.

Application November 4, 1954, Serial No. 466,804

1 Claim. (Cl. 2.57--124) This invention relates to an improved pipe or tubing hanger, and more particularly to a device for readily installing heat exchange tubing in ceiling or walls forming a room space.

While tubing hangers for the purpose indicated have been previously made, nevertheless they are objectionable from the standpoint of cost and the lack of facility with which they may be assembled in relation to the tubing as well as installed by the ereetor.

Accordingly, one of the object-s of the invention is to provide a hanger which is made from suitable strip stock into preformed angular sections which may be readily rolled and punched in simple operations to provide a section having fastening receiving openings in one flange and tubing receiving notches in the other flange. This preformed angular strip may be sheared into sections of the desired length and assembled about the tubing to provide a nailing or fastening ground at either side thereof. Thus, the present invention provides an assembly for continuous sinuous tubing which may be readily manufactured and assembled, and also easily installed by the workman placing fastenings through a selected one of the perforated horizontal flanges to secure the tubing in place.

Another object of the invention is to provide a tubing hanger which lends itself to standard manufacturing practices in its formation and assembly, thereby providing a relatively inexpensive type of hanger which adequately supports the tubing in the wall surface.

With the above and other objects in view which will more readily appear as the nature of the invention is better understood, the invention consists in the novel construction and arrangement hereinafter more fully illustrated and claimed.

A preferred and practical embodiment of the invention is shown in the accompanying drawing in which:

Fig. l is a perspective view of the combined tubing and hanger unit.

Fig. 2 is a detailed cross sectional view on the line 2--2 of Fig. 1.

Fig. 3 is a fragmentary side elevation of the hanger, with the tubing shown in cross section.

Fig. 4 is an exploded fragmentary perspective view illustrating the manner of placing sheared or cut sections of the previously fabricated base stock in assembled relation.

Similar reference characters designate corresponding parts throughout the several figures of the drawing.

Referring to Fig. 1, the tubing designated generally as A is preferably of the sinuous type having spaced parallel flights or legs connected by an arcuate bight portion. The hanger is designated generally as B.

The base stock may be of any length depending upon the type of material selected and may be manufactured by any convenient rolling and punching procedure. The relatively long prefabricated and punched angular sec- 2: tion may then be sheared into suitable lengths and assembled aboutthe tubing A as shown in the drawings;

As intended to be indicated by Fig: 4, the hanger or frame element B is formed from a continuous strip of stock of angular cross section. The flange 1 of the stock is provided with a linear series of spaced openings or perforations 2 while the flange 3 is provided at spaced intervals with the re-entrant notches 4.

Again referring to Fig. 4, it will be observed that the flange 1 may be provided with fastening receiving openings 2 while the flange 3 may be provided with the notches 4% As will be apparent from Fig. 2, the notched flanges 3 and 3 are placed in parallel relation with the edges of their inner flanges resting in the included angle of the other section so that the longitudinal edges of each notched flange abut the perforated flange of the adjacent angle member, with the notches 4 and 4 in registry about the tubing A. The juxtaposed flanges 3 and 3* may then be secured together by spot Welds S to rigidly secure the hanger to the tubing and also maintain the flights of the tubing in proper relationship to obtain adequate diffusion of heat exchange in relation to the wall in which the tubing and the hanger are eventually enclosed in the conventional manner.

It will thus be seen that when the mating angle sections are assembled and spot welded together the notches 4 and 4 securely embrace the tubing and the flanges 1 and 1 having the openings 2 are exposed at either side of the plane of the tubing B.

When the hanger or supporting frame element and the tubing have been arranged in the assembly as shown in Fig. 1, a nailing ground or flange is provided at either side of the plane of the tubing so that no matter which side the erector sees fit to secure in the wall, he will have an available nailing ground in the form of the perforated flange 1 or its counterpart 1.. Thus, considerable time and labor are saved in installing the combined tubing and hanger, and, since the fastening and receiving openings 2. are spaced throughout the flanges 1 and 1 at relatively close intervals, there will be no diiflculty in securing the selected flange to rafters or studding.

The hanger as shown assembled in Figs. 1-3 includes a medial body formed by two flange thicknesses which will securely embrace the tubing, and, at the same time, the perforated nailing flanges project from both sides of the body and enable the erector to readily nail the hanger from either side thereof, to the joist or studding.

From the foregoing it will now be observed that the present invention has as its distinctive feature the provision of a tubing hanger which may be readily and conveniently made and which in its assembled form in relation to the tubing provides a unit which may be readily and easily handled by the erector during installation which will adequately support the tubing in the concealed portion of the wall or ceiling so that, for example, the tubing and the hanger may both be imbedded in a plaster coat or behind a suitable dry wall sheet.

I claim:

A tubing assembly reversible side for side relative to a support to which it is attached, comprising in combination, a sinuous tube having spaced parallel flights, a pair of longitudinally coextensive, identical angle members each having flanges of substantially equal width, one of said flanges of each angle member being perforated with a series of fastener receiving openings and the other flange having re-entrant spaced notches, said angle members being assembled with the inner faces of their notched flanges secured in abutting aligned relationship and the longitudinal edges of each notched flange abutting the Patented'r July: 15, 1958:
