- BUCKLE Original Filed May 1, 1951 Patented June 12, 1934 UNITED STATES PATENT OFFICE Original application May 1, 1931, Serial No. 534,304. Divided and this application August 6, 1932, Serial No. 627,752

2 Claims. (01. 24-163) Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing, in which Fig. 1 is a view of a preferred form of the buckle shown as applied to a tire chain;

Fig. 2 is a side view of the buckle shown in its locked position, and

Fig. 3 is a sectional view on the line 3-3 of Fig. 1 shown in its locked position.

This device is shown as applied to a so-called mud-hook having a strap 10 of very strong textile material, preferably woven on a narrow ware loom, and capable of resisting any force to which it may be subjected in its use for this purpose.

This strap is a simple straight strap adapted to be passed around the inner surface of the rim and passing between two spokes.

The anti-skid portion of the device comprises a pair of chains 11 or other flexible means for preventing skidding shown arranged parallel to each other. They are secured at one end to the strap 10 inany desired way. One chain, however, can be used within the scope of some of the claims.

At the opposite end the strap 10 is brought through the parts of the buckle frame 15 in the manner shown in Fig. 2. The buckle is formed of a piece of metal having a square or rectangular opening through which the strap passes twice. At one side is an outer bar 21. Across a point at about the center of this opening is a shaft 17 and the frame of the buckle 15 is provided with depressions 18 serving as bearings for this shaft and projections 19 completing the bearings, although these bearings are not covered. The shaft is joumalled loosely in the bearings thus formed and it is provided with an eccentric portion 20 extending practically across the buckle and adapted to come down as shown in Fig. 2, into contact with the strap to hold it against the outer bar 21 of the frame 15 of the buckle when the parts are in locked position. The buckle frame is shown as provided with two opposite side extensions in the same plane having eyes 14 for receiving the ends ofthe chains 11.

In the use of the device, the chains are placed on the outside of the tire, the strap passed through the inside of the rim and between two spokes of the wheel. The end of the strap is passed between the eccentric 20 and the bar 21 from the back, as shown in Fig. 2 and drawn up. It will be understood that at this time the eccentric 20 is in inoperative position and its handle 22 is in the position shown in Fig. 1. The end of the strap is then passed down again through the buckle between the eccentric and the opposite or inner bar of the buckle. Now it is drawn up as tight as possible and the end of the strap is passed in through the space between the strap itself and the bar 21 where it comes out on what may be considered the outer side of the buckle, as appears in Fig. 2. This is drawn as tight as possible and the handle 22 is then turned half way around so that the eccentric 20 binds the two layers of the strap between it and the bar 21. The turning of the eccentric takes up additional slack in the strap and binds it firmly. Stops 30 limit the motion of the eccentric.

Now it will be seen that any force, tending to pull the strap away from this buckle, also tends to pull the eccentric down further toward the Plane of the buckle and toward the bar 21. Therefore, this construction will not be loosened by a pull on the strap which, of course, is an action that it will be subjected to. On the other hand, when it is desired to loosen it, that is done very easily by pulling up the handle 22 'and pushing it over to the position shown-in Fig. 1. In fact it is not necessary to push it over as it will snap itself further around after it has been moved through a quarter of a circle.

Although I have illustrated and described only one form of the invention, I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited in this respect otherwise than as set forth in the claims, but what I do claim is:--

1. As an article of manufacture a buckle for detachably securing the free end of a strap, said buckle comprising a flat frame member having an approximately rectangular opening therein, with a bar on the outer side of the opening, the frame member being formed with bearings, a shaft located in the bearings and having an eccentric portion inside said opening and a handle outside, the eccentric portion being adapted to be turned toward said bar to clamp the strap between it and the bar when the handle is turned outwardly from the flat member.

2. As an article of manufacture, a buckle comprising a frame, a cam pivotally mounted on the frame and adapted for oscillation, said frame being provided with stationary portions forming a passageway of cross-sectional dimensions sufiicient to accommodate two thicknesses of said frame.
