BELT-FASTENER.

Specification of Letters Patent.

Patented Aug. 21, 1906.

Application filed October 17,1905. Serial No. 283,161.b

To all whom it may concern.'

Be it known that I, HARRY G. ELLIS, a citizen of the United States, residing at Clearfield, in the county of Clearfield and State of Pennsylvania, have invented a new and useful Belt-Fastener, of which the following is a specification.

This invention relates to belt-fasteners, and has for its object to provide an improved device of this character which is entirely com lete in itself and is capable of being applie to any ordinary belt without re uiring any material change therein beyond t e formation of openings for the reception of the strap elements of the device. It is furthermore designed to provide a strong and durable connection between adjacent belt ends; to preserve the necessary flexibility of the belt; to facilitate the application of the device, and to prevent wear upon. the pulleys.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and partifnilarly7 pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the sco e of the claims without departing from t e s irit or sacrificing any of the advantages of t ie invention.

In the drawings, Figure 1 is a fragmentary perspective view of adjacent belt ends connected by means of the present invention. Fig. 2 is a fragmentary side elevation of the invention in its relation to a pulley. Fig. 3 is a sectional view of the belt-fastener. Fig. 4 is a detail perspective view of the fastener removed. Fig. 5 is a similar view of a modiication. Fig. 6 is a detail view of a modified form of a flexible loop.

Like characters of reference designate corresponding parts in all of the figures of the drawings.

Referring at first more particularly to Fig. 4 of the drawings it will be noted that the present device includes a pair of parallel duplicate straps 1, each stra being flexible and ormed of leather, rawhi e, or other flexible and strong material. The ends of each strap are folded over so as to overlap, and a fastening 2, preferably a rivet, is passed through the overlapped end ortions of the strap and the middle portion tiiereof, whereby terminal loops or eyes 3 and 4 are provided. Through the corresponding loops or eyes of the two straps are passed pins 5, which maybe smooth, as in Fig. 5, or roughened in any 'suitable manner-as, for instance, by means of transverse notches 6.

In practice the belt ends-such, for instance, as indicated at 7 and 8-are provided with corresponding pairs of openings 9, preferably transverse slots, and the terminal eyes or loops 3 and 4 of the two straps are passed through corresponding openings in the belt ends, after which the pins or keys 5 are thrust through the corresponding loops or eyes of the two belts. When strain is placed upon the belt, the pins 5 will be drawn tightly against the belt and are thereby held against endwise displacement through their frictional engagements with the belt. the belt ends by means of the present fastening care should be taken to place the pins 5 upon the outer side of the belt in order that the intermediate portions only of the straps may come into contact with the pulley, as will be understood by reference to Fig. 2, wherein a portion of the pulley has been indicated at A.

By reason of the flexibility of the straps they can be readily forced through the openings 9 and they also conform readily to the curvature of the pulley, lthereby insuring a. snug 'lit of the belt around the pulley.

While two straps have been shown in the accompanying drawings, it will of course be understood that a single strap will be suflicient for a narrow belt, while a greater number `of straps may be employed for a relatively wide belt.

A very important advanta e of the present invention resides in the act that when strain is placed upon the belt the extremities of the connected sections thereof will be flared outwardly, as showin in Figs. l, 2, and 3 of the drawings, whereby the connecting straps or loops will come into the space vacated by the belt ends and lie in the plane of the belt. The advantage of this peculiar disposition of the straps or loo )s is that they pass around the ulley precisely in the same manner as the ot er portions o the belt and there is no im act of the fastening means with the face o the pulley, Wherefore there is no dama e to the pulley nor to the fastening means w ien the connected ends of the belt pass around the pulley. The pressure a plied to upset the rivets of course sinks t e ends of the latter into the straps or loops, wherefore the metallic rivets do not strike In connecting.

IOO

the face ol' the pulley, and the latter is subjected to engagement by the flexible belt and the llexible straps or loops only, which precludes the possibility of damage to the pulley by the present belt-fastening device.

By i'eason of the outward flaring of the connected ends of' the belt the pull of the straps or loops does not come upon the outer edges of the openings in the belt, but upon the pins or bars, while the latter bear throughout their lengths transversely across the entire width of the belt, wherefore a very strong and durable connection. is y)reduced and there is little or no liability o the fastening becoming torn out ol the belt.

While I prefer to connect the overlapped ends of the strap or loop to the middle portion thereof, I also contemplate the fastening of the overlapped end portions only7 as shown at 10 in Fig. 6 of the drawings.

From the foregoing description it will be understood that the belt-fastener of the present invention is entirely complete in itself and capable of being put upon the market independent of the belt. Moreover, it is capable of being conveniently engaged with belt ends without requiring any particular degree of skill or ex erience and when applied preserves the desired flexibility of the belt and at the same time maintains a strong and durable connection between the belt ends.

Having thus described the invention, what is claimed isl. A belt-fastener comprising a series of independent looped straps, and pins for insertioii within the opposite end portion of the looped straps, each strap being flexible to conform to the condition ol' the belt throughout its path of movement.

2. A belt-fastener comprising a llexible loop having its o posite sides connected together between t ie ends ol the loop to forni terminal eyes, and pins for engagement with. the respective eyes.

3. A belt-fastener comlnising a flexible. strap having its ends folded over and secured to the strap to form terminal eyes, and pins for engagement with the respective eyes.

4. A belt-fastener comprising a llexible strap having its ends folded over and overlapped to form terminal eyes, the overlapped end portions being seeured to the middle portion of the strap7 and pins for engagement with the respective eyes.

5. As an article of manufacture, abelt-lastener comprising a pair of llexible straps, each strap having its ends folded over and` overlapped to forni tern'iinal eyes, fastenings piercing the overlapped ends and the middle portions of the respective straps, and pins removably engaging the. corresponding eyes of the straps.

In testimony that lv claim the foregoing as my own l have hereto affixed my signature in the presence of two witnesses.
