BELT-COUPLING.

SPECIFICATION forming part of Letters Patent No. 792,947, dated June 20, 1905.

Application filed November 10, 1904. erialNo. 232,239.

To all whont it may concern.-

Be it known that I, WILLIAM H. TIMs, a citizen of the United. States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented new and useful Improvements in Belt-Couplers, of which the following is a specification.

My invention relates to belt-couplers; and its primary object is to provide a new and useful device of this character by means of which the ends of a belt may be effectually united without resorting to the use of lacing, rivets, and their equivalents.

Afurther object of the invention is to provide a coupling of the above-stated character which can be struck up from a single blank of sheet metal, whereby its cost of manufacture is reduced to a minimum, and one which is durable and efficient.

With the above and other objects in view the invention consists in the construction and arrangement of parts hereinafter fully described, claimed, and illustrated in the accompanying drawings, in which is disclosed the preferred form of my invention, and in which Figure 1 is a plan View of a belt-coupler constructed in accordance with my invention.

Fig. 2 is a central transverse sectional view thereof; and Fig. 3 is a view similar to Fig. 2, illustrating the application of the coupler to a belt.

' Referring to the drawings by reference-numerals, like numerals designating like parts in the several figures, 1 designates the coupler, and 2 the belt, the ends of which are adapted to be united by the coupler, as disclosed in Fig. 3 of the drawings. The coup ler is struck up from a preferably rectangular blank of sheet metal to provide side bars 3 and a center bar 4. The coupler has its ends 5 bent downwardly at right angles with relation to the bars 3 and 4, whereby to add rigidity and strength to the structure. The bars 3 have their inner longitudinal edges provided with teeth 6, which are formed on said bars 3 during the operation of stamping the coupler and are bent downwardly in opposite directions to dispose their extremities below the bar 4, as fully disclosed in Fig. 2 of the drawings. This disposition of the extremitics of the teeth 6 provides spaces 8 between the teeth and edges of the bar 4 and is adapted to permit of the ends of the belt 2 being inserted therethrough to position its extremities above the coupler and to be brought into engagement with the edges of the bar .4, After the ends have been thus inserted a slight reverse pull will cause the teeth 6 to engage the upper surface of the belt and bring the extremities of the belt into engagement with the bar 4, as is fully disclosed in Fig. 2 of the drawings, thereby obviating all liability of the ends becoming uncoupled. The peculiar disposition of the teeth and the engagement of the bar by the ends obviates all liability of the accidental uncoupling of the belt when a slack occurs in the belt.

It is apparent from the above description, taken in connection with the accompanying drawings, that I provide a coupler by means of which the ends of a belt may be effectually united and that by providing a coupler which may be struck up from a single blank of material I provide one which is cheap to manufacture, durable, and efficient.

Having thus fully described the invention, what is claimed as new is A belt-coupler comprising a single piece of flat metal having formed therewith by stamping therefrom a central bar and side bars, the ends of the metal being turned down to reinforce the coupler, and V-shaped teeth formed complete on the inner edges of said side bars during the operation of stamping the article, and said teeth being bent downwardly in an inclined position so that their points will be below or out of line with the opposite edges of the center bar, substantially as specified.

In testimony whereof I aflix my signature in presence of witnesses.

WILLIAM H. TIMS.
