PATENT JOHN COLLIS, OF DES MOINES, IOWA, ASSIGNOR TO WILLIAM P. COLLIS, OF NEW YORK, N. Y.

PIPE-HANGER.

SPECIFICATION forming part of Letters Patent No. 716,192, dated December 16, 1902.

Application filed May 17, 1901. Serial No. 60,650. (No model.)

- aZZ whom it may concern.-

Be it known that I, JOHN OOLLIS, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented certain new and. useful Improvements in Pipe-Hangers, of which the following is a specification.

The objects of my invention are to provide a pipe-hanger of simple, durable, and inexro pensive construction, that may be attached to a floor, beam of wood, or metal, and of any ordinary size or shape, to support a pipe in 'such a manner that the unavoidable movements of the pipe due to the contraction and r5 expansion of the metal may be provided for and that without interfering with the hanger and without impairing its attachment to the beam.

My invention consists in certain details in the construction, arrangement, and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 shows the complete device applied to a metal beam, with parts of the pipe-clip broken away to show certain details of construction. Fig. 2 shows a modified form of 0 the complete device applied to a metal beam. Fig. 3 shows the clamping portions of the hanger applied to a wooden beam. Fig. 4E showsa modified form of the hanger designed for attaching pipes directly to flat surfaces.

3 5 Fig. 5 shows an enlarged detail sectional view of the top portionof theclip.

Referring to the accompanying drawings, it will be noted that I attach the hanger to a metal beam by means of two supports, each of which is made from a short metal brace having two openings formed therein, and having one end (indicated bythe numeral 10) shaped to fit the top of the flange of the metal beam. The remainder of the brace is substantially U-shaped and indicated by the reference-numeral 11, its other end being designed to engage the under surface of the metal beam. These braces are made from pliable metal, so that the part 10 may be adjusted to the general contour of the beam to which the device is to be clamped, and the other end, in

engagement with the under surface of the beam, will prevent a swinging movement of the said brace after it is adjusted to position. In use, the braces are first made substantially U-shaped, with the end 10 longer than the other end. Then they are placed in position, and the end 10 is bent downwardly to fit the beam to which it is clamped, thereby insuring an accurate fit to a beam of any shape. The rod 12 is screw-threaded at the ends and is passed through the openings in said braces, and the nuts 13 are screwed on the ends thereof until they engage the braces. Obviously this rod may be made of comparatively great length and then cut to a desired size. Mounted on the central portion of the rod 12 is a cylinder 14, capable of a rocking movement on the rod 12 and also capable of sliding longitudinally thereon. Cast integral with the cylinder 14: is a collar 15, internally screw-threaded and connected with the cylinder 14 by the uprights 16. A pipe or rod 17, screw-threaded on both ends, is screwed into the collar 15. 7

The pipe-clip is coiiiposed of two semicircular pieces 18 and 19, hinged together at 20, the part 18 having a screw-threaded end designed to receive the pipe or rod 17, and the part 19 having an opening 21 in its end overlap- 8o ping the opening in the part 18 designed to admit thepipe or rod 17.

In the modified form shown in Fig. 2 a frame or yoke 22 is provided, having a screw-threaded portion 23, designed to enter the collar 15. The upper portion of the frame or yoke is provided with a straight edge track 24, and a rounded rod 25 is mounted in the frame or yoke beneath the straight edge 24:- A grooved wheel 26 is placedin the frame or yoke, with the rod 25 and the straight edge 24': both admitted into this groove. Depending from the axle 27 of the grooved wheel-26 is an internal]y-screwethreaded collar 28, designed to receive the pipe orrod 17. 5

In the modified form shown in Fig. 4 a hanger is shown composed of a plate 30, designed to be screwed to a fiat surface and having a downward extension 31, externally screw-threaded to receive the pipe or clip, I00 and when this modified form is used the parts of the pipe or clip are connected by means of a bolt and nut 32 and 33, so they may admit a pipe after the clip is in position.

In practical use it is obvious that the U- shaped braces may be attached to a beam of any size or shape readilyand quickly by bending the ends 10 to overlap the top of the beamflange. lhen the rods 12 are cut to the desired length, passed through the cylinder 14, and then through the U-shaped braces, and the nuts 13 screwed to their ends until the parts are firmly held in position. Then the screwthreaded pipes or rods 17 are cut to the lesired length and screwed into the collar 15. Then the clips are placed on the pipe, and the pipe or rod 17 is turned in the collar 15 to enter the screw-threaded portion of the clip, whereupon the pipe is firmly secured in position, and yet a slight movement in any direction is possible. Where it is desired to permit a greater movement than is possible in connection with the use of the form shown in Fig. 1, the frame or yoke 22 is placed on the hanger, and the clip is supported from the wheel 26.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, therefore, is-

1. In a pipe-hanger, the combination of two substantially U-shaped flat metal braces, each having one end designed to overlap the flange of an I-beann, andhaving its other end designed to rest against the under surface of the same flange, said braces having openings extending transversely through them, a bolt passed through the openings, beneath the I- beam, nuts on the ends of the bolt to engage the outer surface of the braces and a pipesupporting device mounted on the bolt be tween the braces, for the purposes stated.

2. An improved pipehanger comprising in combination two "substantially U-shaped braces each having one end longer than the other and projected upwardly and in a direction toward the other end, said longer ends being adapted to overlap the flange of an I- beam and the short ends adapted to engage the bottom of the same beam, a rod passed through both upright portions of said U- shaped braces, a cylinder slidingly mounted upon thecentral portion of said rod between the U-shaped braces and having a screwthreaded collar connected therewith, a screwthreaded pipe or rod to enter the said screwthreaded collar and to project downwardly, and a pipe-clip having a screw-threaded opening to receive the said pipe or rod. 1

3. In a pipe-hanger the combination with a frame or yoke having an upwardly-projecting screw-threaded extension and also having a horizontal track at its upper portion, a detachable rod in the bottom portion of the frame or yoke parallel with the said track, a grooved wheel between the said rod and track and of a size and shape to admit both the rod and track into this groove and to be capable of movement longitudinally of the rod and track, and a sore w-threaded collar extended from the axle of the grooved wheel for the purposes stated.

4:. An improved pipe-hanger, comprising in combination, a clamp capable of being socured to a beam, a bolt supported by said clamp in a horizontal plane, a bracket on the bolt capable of swinging in a vertical plane, a frame or yoke having ascrew-threaded extension, said extension seated in said bracket, a horizontal track at the upper part of the frame or yoke, a detachable red at the bottom of the frame oryoke parallel with said track, a grooved wheel between the rod and track and of a size and shape to admit both the rod and track into its groove and to be susceptible of movement longitudinally of the rod and track, a screw-threaded collar supported on the axle of the grooved wheel, and a pipeclip comprising two segmental parts hinged together, the free end of one part being provided with a screw-threaded opening and the free end of the other part being provided with a smooth opening of a larger diameter than the screw threaded opening and designed to overlap the end having the screw-threaded opening, and a screw-threaded pipe or rod having one end seated in the said screwthreaded collar and the other end passed through the smooth opening and seated in the said screw-threaded opening, substantially as and for the purposes stated.
