To all whom it may concern: j Be it known that 1, CHARLES DI T- RICH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Suspension-Clamps, of which the following is a specification, ref erence being had to the accompanying 'draw-' ing, forming a part thereof.

My invention relates to improvements in.v

clamps, for suspending from overhead girders, or the like, shafting, machinery, pipes and other appliances and objects, the type' of clamp to which my invention relates involving means for overlappingly engaging flanges on the overhead girders. 1

My objects, generally stated, are, to provide a clamp of such construction that it may be applied to operative position on girders of different Widths, and with basefianges of different thicknesses, and which shall be of simple and economical construction and readily applied for use ;v and to provide improved, simple and economical means for suspending objects from the'clamp.

Referring to the accompanying draw- 1ng Figure 1 is a View in sectional elevation of the preferred form of my clamping device, showing it as applied to an I-beam' girder, also shown in section and partly broken away, with a beam shown in section and partly broken away, supported from the clamp, the section being taken at the line 1 on Fig. 2 and viewed in the direction of the arrow. Fig. 2 is a section taken at the line 2 on Fig. 1 and viewed in the direction of the' arrow. Fig. 3 is a section taken at the. line 3 on Fig. 2 and viewed in the direction of the arrow; and Fig. 4, a section taken at the line 4 on Fig. 1 and viewed in thedirection of the arrow.

My improved clamp is provided, more particularly, for cooperation with the girders in a ceiling of a building, whether the girders be exposed or concealed in the finished structure, though it willbe readily understood that the invention is not'limited to such a structure.

My improved cap as I prefer to construct it, comprises a pair of similar jaw-members 5 provided along' their upper edges with inwardl'y 'extending flanges 6, at which the is adapted to fit over thel pper surfaces of the flanges 7 of the girder, such'as that represented at 8-, and from which the at 15, and preferably serrated, and a lower block 16 having its upper surface oppositely inclined, as illustrated at 17 and also preferably serrated, theblocks 16 resting preferably on inturned, flanges 18 on the lower ends of the aw-member 5, against the lower surfaces of which latter the part to be suspended, as for example the beam represented at 19, andsecured to the clamp as hereinafter described, bears, and washers 20 surrounding the bolt 9 and located between the nuts '11 and the blocks 13 and 16.

Thefianges 18 are preferably provided at their opposed'edges with openings 21, preferably of semi-circular shape, to receive a bolt 22 which passes through the beam 19 and carries a nut 23 on its lower threaded end. The head 24 of the bolt, which is of angular shape, is adapted to seat in a simi larlyshaped recess 25 in the upper surface of a block26, which rests upon the upper surfaces of the flanges 18, and is held thereon against accidental displacement by depending flanges 27 which fit over the sides of the flanges 18, as represented in Fig. 2.

The manner of using my improved clamping means is as follows: Assuming that the clamp is to be applied to a girder,-such as the girder 8, the nuts 11 are first screwed upon the bolt 9 from opposite ends thereof, and the washers 20 then applied to the bolt. The blocks 13 and jaw-members 5 are then applied successively to the bolt 9 to surround the latter and to cause the members 5' at their projections 6, to overlappingly engage the flanges 7 of the girder, the nuts 12 being then applied to the ends of the bolt 9. In the operation of applying the members 5 to the bolt 9, the bolt 22, inserted through the block 26, is introduced into the registering recesses 21 in the flanges 18 to position it in place and position the block 26 on these flanges. The blocks 16 are then inserted. into place under the blocks 13 and adjusted relatively to the latter to cause the upper blocks 13 to snugly fit against/the under sides of the flanges 7 and the nuts 12 then tightened against the members 5. In this position of the parts, the serrations on the opposed inclined surfaces 15 and 17 hold the cooperating blocks 13 and 16 in adjusted position, and both the upper and lower blocks are held against lateral displacement by the Washers 20. The blocks 13 and 16 thus serve to adapt the clamp to be applied to girders having flanges of varying thicknesses, and the adjustment of the various parts along the bolt 9 permits of the use of the clamp with girders having base-flanges of varying widths. i

The bolt 22 serves as a means of attaching the beam 19 to the clamp,.this being accomplished by positioning the beam to cause the bolt 22 to extend through an aperture therein, and then applying the nut 28 to the position illustrated in Fig. 1. The recess in the block26, which is held against turning, prevents the bolt 22 from turning, and serves this purpose regardless of the adjustment of the jaw-members crosswise of the girder 8, thus permitting single attaching means being employed for the beam.

'l/Vhile I have illustrated and described a particular construction of-clamping means embodying my invention, I do not wish to be understood as intending to limit it thereto, as the same may be variously modified and altered without departing from the spirit of my invention. v

lVhat I claim as new, and desire to secure by Letters Patent, is:
