T0 (LZZ whom t may con/cern,.-

Be it known that I, EDWARD BARTHOLO- MAY, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented new and `useful Improvements in Devices for Fastening Gras-Pipes, of which the following is a specification.

The invention relates to an improvement in pipe-hangers and supports designedi particularly for use in connecting supply-pipes with fixtures, as ceiling-beams, in dwellings.

The main object of the invention is the production of means arranged for removable connection with the pipe and for adjustable connection with a suitable hanger-bracket designed to be secured to the fixture.

The details of structure will be described in the following specification, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of a hanger constructed in accordance with my invention, a short length of pipe being shown in place therein. Fig. 2 is a side elevation of the same, the bracket-plate and a portion of the arm being broken away. Fig. 3 is a transverse section through the bracket-arm.

Referring tothe drawings, my improved hanger comprises a bracket-plate 1, preferably of thin metal, provided with suitable openings 2, designed to receive screws or other fastening means by which the bracket may be secured to the desired fixture. One end of the plate is provided with a depending flange 3, to which is secured the depending arm 4. The arm 4, which may be of any length desired, is preferably plane on its sides, but formed with V-shaped grooves 5 in its front and rear faces, whereby to provide additional holding edges,- as will be hereinafter explained.

The hanger proper includes a bar 6 of a length greater than the width of the arm 4, formed with transversely-arranged openings 7, (shown in dotted lines in Fig. 2,) so positioned that when the bar is in position the openings 7 are'in alinement with the sides of the arm 4, as clearly shown in Fig. 1.

The hanger-strap comprises a metallic bar preferably round in section and centrally formed in a return-bend 8, the terminals of said bar being projected in parallel relation and threaded, as at 9. Immediately adjacent the bend 8 the two arms of the strap are curved to provide a pipe-receiving bend 10, said strap being of such length and the bend 10 so located that the pipe 1l when held therein may rest snugly against the front wall of the arm.

In use my improved hanger is secured to the desired fixture, as previously described. The terminals of the strap are passed through the openings 7 in the bar 6 and secured therein by nuts 12 and the bend l() of said strap arranged to engage the pipe, as shown, it being understood that the nuts are tightened until the pipe 11 is securely clamped against the front face of the arm 4, in which position the bar 6 will be securely clamped against the rear face of the arm.

In the tightening of the parts described the function of the V-shaped grooves in the front and rear faces of the arm 4 is apparent, as said groves provide sharp edges on said faces of the arm to bite into the pipe and bar, respectively, under the clamping action of the parts, and thereby materially assist in holding the parts.

While I prefer that the strap be formed prior to its introduction through the bar 6, it is obvious that said strap may be formed without the bend 10 and bent about the pipe after its introduction through the plate 6.

While I have shown the hanger as arranged for connection to an overhead fixture, it is obvious that it is equally applicable to a base or a side fixture. A

It is equally apparent that the bar 6 and hanger-strap are adjustable longitudinally of the arm 4 to provide for anydesired elevation or position of the pipe.

Having thus described the invention, what I claim as new is 1. A pipe-hanger comprising a bracket adapted to be secured to a fixture and formed on opposite faces with V-shaped grooves, a pipe-supporting member adjustable on said bracket, said member being provided with means for drawing a pipe into binding engagement with the edges of one of said grooves. f

2. Apipe-hanger comprising a plate adapted to be secured to a support, an arm depending therefrom and formed in one face with a longitudinally-arranged V-shape groove, and

a pipe supporting member longitudinally adjustable on the arm and provided with means for drawing a pipe into binding engagement with the edges of said groove.

3. A pipe hanger comprising an arm formed on one face with a longitudinally-extending V-shaped groove, and a pipe-supporting member, and means for drawing the pipe supported by said member into engagement with the edges of said grooves.

4. In a pipe-hanger, a plate, an` arm depending thererom and formed with a longitudinally-arranged V-shaped groove, and a pipe-support comprising a bar to engage the edges of one groove in said arm, and a hangerstrap formed of a single length of material and bent to provide parallel terminals, and means to secure said strap-terminals to said bar, said means operating to force the bar into engagement with the edges oi said groove.

5. In a pipe-hanger, a plate, an arm dependin therefrom and Jformed with longitudinall -arranged V-shaped grooves, a bar to engage the edges of one of the grooves of said arm, and a hanger-strap formed of a single length oiV material and bent to provide parallel terminals, the bar being formed with openingsy to receive said terminals and nuts to engage said terminals and adapted to draw the pipe and the bar into engagement with the edges of said grooves.

In testimony whereof I ajX my signature in presence of two witnesses.

EDWARD BARTHOLOMAY.
