Application filed December 16, 1925. Serial No. 75,834.
This invention relates to hangers and has for its object the production of a device of this character which may be adjusted to clamp it upon I beams or similar supports regardless of the width of the support.
This object is attained by the mechanism illustrated in the accompanying drawing.
For the purpose of illustrating the invention one preferred form thereof is illus trated in the drawings, this form having been found to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized, and the invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described except as required by the scope of the appended claims.
Of the drawings:
Figure 1 represents an elevation of a hanger embodying the principles of the present invention, shown clamped to a supporting member and having depending therefrom. a rod adapted to support a rail or other element.
Figure 2 represents a plan of the same removed from the supporting I beam and showing the depending rod in section.
Figure 3 represents an elevation of the inner side of one part of the hanger.
Figures represents an elevation of the outer side of one part of the hanger.
Figure 5 represents a vertical section of the lower end of one part of the hanger, and
Figure 6 represents a vertical section of the lower end of the other part of the hanger.
Similar characters indicate like parts throughout the several figures of the drawm s.
Tn the drawings 10 is a portion of an I- beam having the outwardly disposed flanges 11. Supported by these flanges 11 is a hanger made in two parts 12 and 13, these two parts being exactly the same and interchangeable.
The upper end of each part 12 or 13 is provided with a toe 141 which rests upon the upper face of a flange 11.
The lower end of each part 12 or 13 is provided at one side with an outwardly extending trunnion 15 and on the opposite side of each part is an car 16 having an opening 17 alined with a trunnion 15.
The trunnion 15 of'one part is adapted to be posltloned in the opening 17 inthe other part forming a hinge whereby the two parts 12 and 13 may be moved about theaxes of the trunnions 15.
This means of connecting the two parts 12 and 13 makes it possible for the upper ends of the parts 12 and 13 to be adjusted toward and from each other to fit different widths of flanges 11 of the I-beams from which the hanger is adapted to depend.
Near the upper end of each part 12 and 13 1s hole 18through which extends a bolt 19 having a head 20 at one end and a clamping nut 21 threaded to the opposite end. These holes are so disposed beneath the toe 14; that the bolt 19 will bear against the under face of the T-bQELHl.
l Vhen the nut 21 is properly adjusted upon the bolt 19 the inner faces of the parts 12 and 13 will be forced into contact with the outer edges of the flanges 11 with the toes 14: resting upon the upper surface thereof, as'indicated in Fig. 1.
The width of the hole 18 is the same from the inner face of each part 12 and 13 to the outer face thereof but the upper and lower walls 22 and 23 thereof are inclined as indicated in Fig. 1, the inner end of the hole having a greater height than the outer end as shown. 7
This formation of the holes 18 makes it possible for the two parts to'be adjusted relatively to each other about'the axis of the trunnions 15 to fit a very narrow flange 11 or a very wide flange.
Tn other words, when the hangar is to be suspended from a fixed structure like an I- beam in installing a system of overhead trackage, the workmen are liable to find a variety of sizes of I-beams in the structure from which the hangers are to be suspended.
With a hanger constructed as herein shown the same hanger may be adapted for use in connection with any size or shape of I-beams.
The lower end of each part on its inner face has a recess 24- adapted to receive a rod 25 which said hanger is designed to support.
This rod 25 has a nut 26 threaded to its upper end which rests upon the upper surfaces 27 of the inwardly extending ears 16 at the lower end of the parts 12 and 13.
The width of the recesses 24 is the same as the diameter of the rod 25 but the inner so I walls of said recesses are curved as indicated at 28 to permit the two parts 12 and 13 to be moved about the axis of the trunnions 15 without any portion of the wall 0]": the recess impinging upon the rod 25.
In installing this hanger the two parts 12 and 13 are positioned out of alignment with the trunnion of each part positioned in the recess of the other part and then by lateral movement of these two parts the trunnions maybe inserted into the openings 18 with the two parts 12 and 13 in the same plane.
The upper ends or" the parts are then clamped to the supporting Lbeain as hereinbefore described. The rod is then in serted into the recesses 2i and the nut screwed thereon.
When the rod 25 is thus positioned in the recesses 24, it is obvious that the two parts will be locked together and cannot be disconnected until the rod25 again removed from the recesses.
, The lower end of the rod 25 may be connected to any member which it is desired to suspend from the hanger and the height of the member maybe varied by adjusting the position of the nut 26 on said rod.
This makes a very simple but effective construction'of hangers which is adapted to be adjusted for use in connection with a variety of shapes of I-beams from which it is to be suspended.
It is believed that the-operation and many advantages of the invention will be under stood without further description.
Having thus described my invention, I claim 7 l. A hanger consisting of two parts having overlapping lower ends connected together by a trunnion formed integral with each part and positioned in a hole in the other part, said parts being provided at their upper ends with oppositely disposed pro ections extending toward each other, and means for connecting the upper ends of 7 said parts.
:2. A hanger consisting of two parts each of which has at its lower end a rod-receiveach of which has at its lower end a recess and a trunnion adapted to be positioned in a hole formed in the other part, a rod disposed in said recess and preventing the disengagement of said trunnion, a nut threaded to the upper end 01" said rod and supported on the lower ends of said parts, and clamping means coacting with the upper ends of said parts.
5. A hanger consisting of two like parts each of which is provided with a projecting too at the top and has at 'thebottom a projecting portion provided with a rod-receiving recess and a trunnion adapted for insertion in a hole in the other part, clampng means coacting with the upper ends of :said parts, a rod in said recess, and a member thereon supported by the lower projections.
6. A hanger consisting of two parts -'ex actly alike and interlocked at the lower end by laterally extending elementsi'orm'ed integral therewith and movable about the axes of the interlocking elements, said partshaving opposed vertical semi-cylindrical rod receiving recesses in the opposed faces of their lower ends and at their 'uo tier ends down-- wardly curved toes extending towards each other, and means for clamping the upper ends of said parts against the flanges of a supporting member. 7
