BUCKLE.

Specification of Letters Patent.

Patented Mar. 11, 1913.

Application filed October 7, 1912. Serial No. 724,356.

To all whom it may concern:

Be it known that 1, JOHN C. RosEN- KRANZ, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Buckle, of which the following is a full, clear, and exact description.

The invention relates to one-piece buckles such as are used on cloth tightening bands or straps employed for tightening trousers, vests and other garments and also used as encircling bands and belts.

The object of the invention is to provide a new and improved one-piece buckle arranged to permit easy adjustment of the band or strap and to hold the strap securely in adjusted position without the use of tongues, teeth or similar holding or gripping devices.

In order to accomplish the desired result the buckle is made of a single piece of metal and comprises side bars, end bars integrally connecting the ends of the side bars with each other, and a middle cross bar integrally connecting the side bars with each other at the middle thereof, the inner edges of the side bars converging from the middle bar to the end bars.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the buckle as attached to one end of a strap, part of the latter being broken out; Fig. 2 is a similar view of the buckle as applied for holding the other end of the strap in the adjusted position; and Fig. 3 is a sectional plan view of the buckle.

The buckle is formed from a single piece of metal, preferably sheet metal, stamped to provide side bars A, A, end bars B, B integrally connecting the ends of the side bars A, A with each other, and ametal cross bar C integrally connecting the side bars A and A with each other at the middle thereof. The inner edges A A of the side bars A and A converge from the middle cross bar C to the end bars B, B, as plainly indicated in Fig. 1, so that the openings formed in the opposite sides of the middle cross bar C become gradually annular from the mid dle cross bar C to the end bars B, B. One end D of the cloth D is secured to the cross bar G and the other end D of the strap D is made somewhat wider than the buckle openings at their widest parts, that is, adjacent the middle cross bar G, to cause the end D of the strap to strongly bind at the inner edges A A at the time the end D is engaged with the buckle, that is, is passed under the end bar B over the middle cross bar C and the attached end D of the strap D, and then under the end bar B, as plainly indicated in Fig. 2.

It will be noticed by reference to Fig. 2, that, owing to the converging edges A A the wider end D of the strap D is caused to wrinkle or double up from the middle bar C to the end bars B, B, thereby causing a.

firm binding of the end D of the strap, with a view to hold the same against movement on pulls on the strap in the directions of the arrows indicated in Fig. 2. In order to increase the tightening of the strap end D the side bars A and A are arched, as indicated in Fig. 3, so that the cross bar C is somewhat higher than the end bars B, B and consequently the portion of the end D is more pronouncedly curved or arched between the end bars B and B, thus causing the end D to bear firmly on the end D attached to the middle cross bar C.

It is understood that the terminal of the end D overlies the portion of the end D from the middle cross bar C to a distance beyond the end bar B and consequently the frictional contact'between the said ends D and D tends to hold the end D fro-1n disengaging the buckle on the exertion of pulls in the direction of the arrows previously mentioned.

In practice, the sidebars A and A and the end bars B and B are preferably provided along their outer margins with depending flanges, as plainly indicated in Fig. 3, to render the buckle exceedingly strong and durable, and also to provide an gular edges bearing on the end D of the strap at the time the end D is engaged with the buckle, as shown in Fig. 2. The end D can be readily drawn forward through the buckle by the user for tightening the strap to the desired degree, but as soon as the wearer releases the strap and pulls are exerted on the ends D and D in opposite directions, the end I.) is held by the buckle against movement in the direction of the pull exerted on the end D as indicated by the corresponding arrow at the end D The buckle shown and described is. very simple and durable in construction and cheap to manufacture, and it can be readily attached to one end of a strap and used in the manner above set forth.

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

A buckle made from a single piece of metal and comprising side bars, end bars integrally connecting the ends of the side bars With each other, and a middle cross bar integrally connecting the side bars with each other at the middle thereof the inner edges of the side bars converging from the middle bar to the end bars, and the said side bars and end bars being provided along their margins with integral rearwardly extending flanges.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
