WILLIAM G. AVERY, OF CLEVELAND, OHIO, ASSIGNOR TO THE WV. G. AVERY MANUFACTURING COMPANY, OF SAME PLACE.

BIELT FASTENER.

SPECIFICATION forming part of Letters Patent No. 399,962, dated March 19, 1889.

Application filed November 12, 1888- $eria1 No. 290,529. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM G. AVERY, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and useful Improvement in Belt-Fasteners, of which the following is a specification.

My invention relates to improvements in belt-fasteners, and my design is to produce a detachable belt-fastener in two portions for the corresponding ends of the belt without the aid of intervening mechanism, and at the same time to produce a simple form of construction which will distribute the strain over the greater portion of the surface of fastener and relieve the strain on the rivets, and which can be stamped from sheet metal at low initial cost. These objects are attained in the construction shown in the accompanying drawings, and more specifically pointed out in the claim.

In the drawings, Figure l is a section of belt in which the joint is heldby means of two of my improved fasteners. Fig. 2 a 1011- gitudinal section of the same. Fig. 3 is a perspective view of the detached part of the fast ener, and Fig. 4 is a modification of the same. Figs. 5 and 5 show a pin inserted in the T- head to strengthen it.

A and A in the drawings represent the different portions of the fastener, which are formed of thin plates of steel'struck out by a die and afterward bent to the required form.

B and B are rivets passing through the holes C and C in the plates, which serve to bind the faces of the plates together upon the belt. A T-headed slot, 0, is cut in the head inclosing shoulders cl, the T-head cannot possibly get out of the slot of its own accord. The corners c are rounded by pieces of metal left for this purpose, to avoid the sharp edges that might otherwise be left. The rivets B and B are not intended to take the strain of the belt, but are relieved from it by the points f and f, struck from the surface of the clamps, which project into the belt and serve to distribute the strain equally over the belt instead of merely in the line of the rivets. The rivets serve to hold these tightly against the belt and prevent slipping. A modified form is seen in Fig. t, where the points f are struck across the end of the clamp and turned toward each other, effectually holding the leather.

My clamp, being formed of sheet-steel, may be quickly and economically made, and is new in its construction and useful for the purposes for which it is intendedto distribute the strain equally over the belt. 6

It will be observed that my clamp becomes embedded in the belt, and by means of the points on the surface will hold the belt independently of rivets.

In cases where it is desirable to use thin metal for the fastener, or in case of wear, a steel pin may be inserted to re-enforce the T- head, as shown in Figs. 5 and 5.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

The detachable sheet-metal belt-fastener, consisting of the piece A, having a T'-slot, and the opposing piece A, having a T head formed integral therewith, both pieces being provided with inwardly-projecting teeth and rivet-holes, substantially as shown.

WILLIAM G. AVERY.
