JOHN J. FLANAGAN, OF CLEVELAND, OHIO;

BELT-FASTENER- Specification of Letters Patent.

Patented Sept. 18, 1906,.

Application filed April 25, 1905. Serial No. 257,298-

To all whom it may concern.-

Be it known that I, JOHN J. FLANAGAN, a British subject, residing at Cleveland, Guyahoga county, Ohio, have invented a new and useful Improvement in Belt-Fasteners, of which the following is a specification that will enable those skilled in the art to which my invention pertains to make and use the same, reference being had to the accompanying drawings, which form a part thereof.

My invention relates to hinged belt-fasteners. Its object is to make a fastener that will be cheap to make, easy to apply, and very strong in service; and it consists of such features as will hereinafter be fully described and claimed.

In the accompanying drawings, which show my invention in 'general form and details now deemed most desirable by me, Figure 1 is a face view of two belt ends joined by a hinged belt-fastener embodying my invention. Fig. 2 is an edge view of the same. Fig. 3 is a perspective view of a flat stamped sheet-metal blank, which constitutes one of the main elements of my fastener. Fig. 4 is a view of the same when its prongs are bent to form shown and ready for application to the belt end. Fig. 5 is a view of the same member with the prongs pressed through the eyes in the base and their ends bent to secure them against being pulled out. This is the final form of the fastener after its application to a belt end. Fig. 6 is a perspective view of the lower or inner side of one of the belt ends, showing channels for the fastener-prongs to lie in below the surface of the belt.

Each main member A of the fastener consists of a stamped sheet-metal base a, having a series of prongs b and a series of apertures 0 along the center of the base and in line with the prongs, as shown in Fig. 3. The prongs are bent or looped back, as at b, Fig. 4, to form them into pintle-loops, and their ends again bent, as at 6 toward the base, with their extremities pointing at the apertures in the base. This is the commercial form in which the members A are placed upon the market.

In applying the members to a belt the ends D of the belt are first, preferably, punched with a series of holes (1, corresponding to those in the base. The ends of the prongs are then pressed through the holes in the belt and the apertures in the base through which they project, and their extremities are bent down upon the face of the base or otherwise secured by other well known equivalent means in such manner as will secure them against being drawn out of the apertures under heavy strains.

The prongs are preferably square in crosssection and the apertures of small diameter, so that the prong ends must be forced into and through them, this tight fit being an additional precaution against their being pulled out of the apertures.

When the members A are applied to the ends of a belt in the manner shown by Figs. 1 and 2,the pintle-loops b of the opposing me1nbers are brought into position to receive a pintle or coupling-pin O, headed or riveted at its ends, as shown.

Of course the bases of the fastener are applied to the outer surface of the belt, and I prefer to channel the belt on its inner face from the prong-openings to the end, the bodies of the prongs lying in the channels (1 and flush with the surface of the belt, so that no1 lump is formed on the pulley side of the be t.

My fastener as described will preferably be stamped out of sheet-steel, it will be cheap to make and easily applied, will not require an expensive outfit of special tools for its application, will be strong and durable, andform a perfect hinged belt-fastener, with the pintle fairly between the connected ends of the belt and directly in the line of strain.

Having thus described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is

1. As an improved article of manufacture, a member of a hinged belt-fastener having a flat base with a series of prongs projecting therefrom and a series of apertures in the base in line with the prongs, the prongs being bent to form pintle-loops and their extremities again bent toward the base; substantially as described.

2. The combination of belt ends with a hinged fastener composed of members having flat bases with a series of apertures therein, a series of prongs extending from the adjacent edges of the bases and bent to form p1ntle-loops with their extremities again bent and passed through the belt ends and the apertures in the bases and secured against withdrawal, and a coupling-pin lying in alternating pintle-loops of the opposed fastener members substantially as described.

3. The combination of belt ends with a hinged fastener composed of members having pin lying in the alternating pintle-loops of flat bases with a series of apertures therein, a the opposed fastener members; substantially series of prongs extending from the adjacent as described. I edges of the bases and bent to form pintle- In testimony whereof I have signed my 5 loops, their extremities being again bent to name to this specification in the presence of I5 pass through the belt ends and the apertures two subscribing Witnesses.
