UNITED STATES JOHN W. FARLEY, 0F CLEVELAND, OHIO.

PIPE-HANGER.

Specification of Letters Patent. Patented Dec. 14:, 1920.

Application filed January 5, 1920. Serial No. 349,363.

To all 20 ham it may concern:

Be it known that 1, JOHN W'. FARLEY, a citizen of the United States, residing at Cleveland, in the county of Uuyahoga and State of Ohio, have invented certain new and useful Improvements in Pipe-Hangers, of which the following is a specification.

This invention-relates to an improvement in pipe hangers, and the improvement consists more particularly in an insert hanger or suspensory member adapted to be erected and installed upon the false framework or wood form used in building a concrete structure so that when a concrete floor or ceiling is poured and the concrete has hardened and the false frame-work knocked down the said insert hanger or suspensory member will remain partly embedded within the concrete and partly exposed to support a pipe or other load. The device is particularly constructed to facilitate the attachment and placement of the member on the false frame-work and also to anchor it firmly in the concrete, all as hereinafter shown and described and more particularly pointed out in the claims.

In the drawing accompanying this application Figure 1 is a sectional View of a portion of the false frame-work used in erecting a concrete building and showing my improved yoke-shaped hanger or suspensory member seated and secured in place thereon before it is covered with concrete. Fig. 2 is a sectional view portion of the concrete structure with the insert hanger or suspensory member anchored therein and also showing a pipe and an auxiliary hanger suspended from said anchored member. Fig. 3 is a perspective view of one form of my improved hanger. Fig. 4 is a perspective view of a modified form of hanger, and Fig. 5 is a sectional elevation on line 55, Fig. 4. Fig. 6 is a still further modification of the invention.

Now referring to Fig. 1, the false wooden frame-work shown therein comprises an upright wooden piece 2, and a horizontal wooden piece 3 having a chiseled slot or open ing 1- at a predetermined place therein. Through this slot or opening I project the long straight leg 5 of my improved hanger member H until the short right-angled foot 6 at the opposite end of the hanger member is seated flush upon the upper face of wooden piece 3. One or more nails 7 are then' driven through the openings 8 in foot 6 to secure the hanger member in a fixed upright position. As shown the hanger member is of stirrup shape, that is, it comprises a flat strap bent into yoke-shape with a short leg having a foot portion 6. a short cross or connecting horizontal portion 9, and a long depending leg or straight part 5 having a series of openings 17 near its lower end. T he foot portion 6 is about midway between the bow or cross part 9 and the perforated extremity of leg 5 so that this perforated portion will be exposed beneath the frame piece 8 when seated and secured in place thereon.

I also prefer to secure a shortfiat strip 10 t0 the bottom side of the loop or cross art 9 of the hanger member so that an aditional or enlarged supporting surface may be provided for the hanger when it is embedded within concrete. Flat strip 10 may be riveted in place as shown in F ig. 3, or it may be secured to part 9 by lugs 11 struck up from the strip, see Figs. 4 and 5. The foot portion 6 may also be channeled or grooved transversely opposite openings 8 as shown in Fig. 4, so that the nails 7 may be hammered back flush with the bottom surface after the false frame-work has been removed or torn down, or the nails may be out off or clipped short leaving the heads in place, see Fig. 2. I prefer to make this hanger member of flat strap metal, but I may also use a round rod 12 bent into stirrup form with a flattened foot 13 and a flattened perforated straight extension 14, see Fig. 6. All three modifications or forms shown herein have the same stirrup shape with a foot at one side located approximately midway between the upper cross bar and the extremity of the straight depending hanger portion thereof.

In supporting a pipe P an auxiliary hanger member 15 is secured to leg 5 by a bolt 16 inserted through any one of the several bolt openings 17 therein, and usually the pipe P is supported by several of these hanger members embedded in floor or ceiling S at spaced intervals wherever it may be found necessary to run the pipe beneath the floor or ceiling, and the openings 17 permit the pipe to be suspended at different elevations or an inclination relatively tothe different hanger members in the concrete floor. The straight leg portion 5 may be of greater length than as shown herein and a greater number of openings 17 may be used if desired and the openings may be of'any desired shape and form.

What I claim is: r

1. In a pipe hanger, a suspensory member made in one piece bent into stirrup form' to leg and: a long leg parallel to each other and i said short leg provided With a laterally extending foot With holes and said long leg extending beneath said foot portion and provided Withholes to engage a pipe thereon. r

3. A pipe hanger of substantially yoke shape and consisting of a flat strip bent to provide ashort leg with a right-angled perforated foot and a long leg with a straight perforated end and a reinforcing strip affixed transversely to said strip between said legs:

4:. A pipe hanger of yoke shape having a short leg With a lateral foot having chanrnels and nail openings-in said channels and a long. leg having-o bolt openings in its end adaptedto-secure an auxiliary hanger member thereto. v
