BEAM-CLAMP.

To all whom it may concern:

Be itknown that I, OTTo Gr. PAINTER, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Beam-Clamps,of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to-distinguish it from other inventions.

My invention relates to beam-clamps such as are used for engagingthe bases of ordinary I-beams, through the medium of which a hanger may be secured to such beam for the purpose of supporting any desired object, as for instance,-a line of pipe.

The object of theinvention is to provide a beam-clamp which will be economical of manufacture, simple of adjustment and effioient in its operation.

The said invention consists of means here inafter fully described and particularly set forth in the claims.

The annexed drawings and the followin description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of various mechanical forms in which the principle of the invention may be applied.

In said annexed drawings: Figure 1 represents a front elevation of a beam-clamp embodying my invention, showing a fragmentary portion of the depending hanger, and a cross-section of a fragmentary portion of an I-beam, the members of the clamp being shown in their expanded position prior to adjustment to the beam. Fig. 2

represents the parts shown in Fig. 1 showing same adjusted to and engaging the beam base. Fig. 3 represents a side elevation of the beam clamp, the depending hanger and a cross-section of pipe, together with a side elevation of a fragmentary portion of a beam. Fig. 4 represents a front elevation of the parts shown in Fig. 3 showing the members of the clamp in a modified position.

Fig. 5 is a view similar to that of Fig. 1 showing a modified form of clamp. Fig. 6 represents a side elevation of the modified form of clamp and depending hanger of a fragmentary portion of the pipe shown, as well as a cross-section of the fragmentary portion of the beam. Fig. 7 represents a Specification of Letters Patent.

with reference to each other.

vertical section taken upon the plane indicated by line VIIVII in Fig. 6 and Fig. 8 represents a similar section taken upon the plane indicated by line VIII-VIII in said figure.

Theillustrated embodiment of my invention includes two members 1, 1, which are exactly similar in form and construction. One end of each of these members is formed with a hook 2 in the usual manner whereby such end may be caused to engage one side of the base 3 of an I-beam T. The main or body portion 5 of each such member extends substantially parallel with the base of the I- beam when its hook is engaging same as above described, and as illustrated in Fig. 2. This body portion is formed with a longitudinally extending slot 6 which extends through each portion and which is bounded at the top and bottom by two serrated sur-' faces 7, 7 respectively, these surfaces forming alternating teeth and spaces. These surfaces are so formed that the teeth formed by one surface will be disposed opposite to the spaces of the other surfaces, as clearly-shown in Fig. 1. These two members when in their operative position are placed so that the body portions are in juxtaposition to the slots 6 in apposition to each other, the hook portions being at opposite ends of the combined structure thus formed. Extending through the slots is a shank 8 of a bolt 9 and this bolt therefore through the medium of the nut 10 may be used to clamp the two members securely together and prevent'their longitudinal movement The hanger 11 is provided in the usual manner with a plurality of holes 12, through the upper one of which passes the shank of the bolt 9.

In applying the above-described structure, the parts are first assembled, the nut 10, however, being unscrewed so as to permit the parts to be loosely connected. In'

the upper teeth of the one member will be opposite the lower teeth of the other member, as shown in Fig. 4:. This forms a rectangular. space 13 which is almost completely inclosed and through 'which the shank 8 of the bolt extends. The width of the slot and the diameterv of the shank are such that the uninclosed portion of these spaces are narrower than the diameter of the bolt shank, so that the latter, therefore, can move laterally from such spaces, as will be apparent from an inspection of Fig. 2. This construction, therefore, is such that the bolt,

after the parts have been tightened up, and hence the hanger, cannot be displaced in a direction longitudinal with respect to the clamp. I

It sometimes occurs that'the continued application of the Weight carried by the hanger 'will cause the beam-clamp to sag at the center, as shown in Fig. t. When this action occurs, it will be noted that the space 13 still further contracts and still more securely locks the bolt against such described displacement. In the modified form shown in Fig. 5, 1 have provided the outer ends of each of said clamps the body portions of with a protuberance 1 such protuberances being preferably formed by partially punching the metal. out of the said body portion,

by means of a suitable punch and die. These protuberances are of a diametersuch thatthey may enter the slots and are placed on similar sides of, these body portions so that when the latter are placed in their assembled position, the said protuberances will project from the interior or opposed surfaces of the body portions in said slots, as shown. These protuberances therefore prevent the saggingof the two fmembers as illustrated in Fig. 4 and maintain" a substantial parallelism of the said two members to'each other.

Inasmuch as I-beams are of a standard size and the bases thereof are therefore of in place, without dropping or losing any of them during the operation, the result of all of which is a considerable saving of time in the application of the clamp to the beam,
