EMMANUEL EASTWOOD, 21), OF PROVIDENCE, RHODE ISLAND.

BELT FASTEN ER.

fiPECIPICATION forming part of Letters Patent No. 391,695, dated October 23, 1888.

Application filed June 14, 1888. Serial No. 277,060. (No model.)

To ctZZ whom it may concern:

Be it known that I, EMMANUEL EASTWOOD, 2d, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvementsin Belt-Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to belt fasteners or couplings, the same being more especially adapted to be used with round belts; and it consists, essentially, of a metallic sleeve or socketpiece having one or more integrallyformed arms provided each at its free end with a penetrating-lug, the latter adapted to pass through an incision formed in the shell of the coupling and into the leather or material composing the belt, all as will be more fully hereinafter set forth and claimed.

The object of my invention is to cheapen the cost of the class of belt-fasteners referred to, which usually, heretofore, have been secured to the belt by screw-threading, and sometimes by swaging or pinching the metallic shell, thereby reducing its diameter to more securely retain the ends of the inclosed belt. Another advantage resulting from my improvement is that the belt is more firmly fastened to the coupling by reason of the penetrating prongs or lugs. The belt may be readily detached from the coupling by simply raising the free end of the lug-carrying arm.

In the accompanying drawings, Figure 1 represents the ends of a round belt coupled together by means of my improved fastening, aportion 0f the belt and coupling being in section. Fig. 2 is a perspective view of a hook-coupling, each piece thereof having my improved holding device. Fig. 3 is a modified form of the coupling shown in Fig. 1. Fig. 4 is a cross-sectional view taken on line a; x of Fig. 3, showing the holding-prong inserted into the belt. Fig. 5 is a perspective view of a hook-coupling, each half having a single arm. Fig. 6 is a detachedside view of one-half of a hook-coupling, showing the end view thereof.

The construction, arrangement, and operation of myimproved belt-coupling are as follows:

a, referring to the drawings, designates a round belt, made of leather, rubber, or other flexible material, as usual in belts of this class.

A indicates my improved coupling or belt fastening, the same consisting of the shell 0, having one or more integrallyformed arms, (Z, extending throughout a portion of its length, as clearly shown. An elongated opening, d, is cut through the shell adjacent to each ofsaid arms, the shape of the slot and arms being such that when the latter are bent down, as in use, the whole presents asubstantially cylindrical form. The free end of each arm is provided on its under side with a spur or penetratingprong, 6, adapted to pierce the belt. In some forms the coupling consists of two parts, the contiguous ends thereof being linked together by hooks b, as clearly represented by Figs. 2, 5, and 6. The opposite or belt-receiving ends of the coupling are provided with the spurarms d, as before described with reference to the fastener shown by Figs. 1 and 3.

In Fig. lthe coupling is continuous, and is provided with a center tie, m, to which the spurarms are united at each side. In Fig. 3, however, the tieis omitted,and the arms at are reversely arranged that is to say, the spur or free end of one arm is opposed by the connected end portion of the other arm. The dotted lines in the several figures indicate the position of the spur-arms prior to the insertion of the belt.

The manner of connecting the belt by means of my improved coupling is as follows: An end of the belt is reduced slightly, as at a, and then forced into an end of the couplings shell to the desired depth, (the arms d meanwhile being in the position shown by Fig. 6,) after which the arm or arms are forced down into the recess d, thereby at the same time causing the spurs e to penetrate the adjacent end portion of the belt, the operation being next repeated upon the other half of the coup ling. The belt is practically made endless by the use of the coupling shown in Figs. 1 and 3, the ends of the belt being reduced and forced into the respective ends of the couplings shell and the arms next bent down, thereby inserting the spurs 0 into the belt, as before described.

My improved fastening may be made of brass 5 or malleable iron, or it may be produced by the process of dropforging.

I claim as my invention- 1. The improved coupling for round belts hereinbefore described, consisting of an aper- 10 tured shell having integrally-formed arms pro vided with spurs or prongs, constructed and arranged whereby the act of bending the arms downwardly causes the prongs to penetrate the belt, substantially as shown and described.

I 5 2. The belt-coupling hereinbcfore described, nconsisting of the two apertured socket portions having means,substantially as described,
