BUCKLE Filed Nov. 27, 1941 INVENTOR FRED BRAUN ATTORNEYS Patented Apr. 20, 1943 UNITED STATES PATENT OFFICE BUCKLE Fred Braun, Milwaukee, Wis.

Application November 2'7, 1941, Serial No. 420,648

2 Claims.

This invention appertains to buckles, and more particularly to a novel buckle particularly adapted for adjustably receiving the shoulder straps of a pair of overalls.

One of the primary objects of my invention is to provide a buckle which can be readily and quickly applied to a strap, and. which will grip the strap in such a manner that slipping of the strap will be prevented.

Another salient object of my invention is to provide a buckle having a body formed from a single piece of metal including companion jaws having cooperating members thereon for gripping the strap without puncturing or tearing the same.

A further important object of my invention is to provide inwardly directed gripping flanges formed on the longitudinal sides of the jaws, with the flanges of one jaw out of longitudinal alinement with flanges on the other jaw, whereby the flanges on the jaws will firmly grip the strap therebetween.

A still further object of my invention is to provide cooperating struck-in ribs on the jaws for reinforcing the jaws and for gripping the strap, with the ribs arranged between the flanges, so that the strap is caused to take a sinuous path through the buckle.

With these and other objects in view, the invention consists in the novel construction, arrangement, and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawing, in which drawing:

Figure 1 is a front elevational view of the buckle, showing the same in use, parts of the figure being shown broken away and in section to illustrate structural detail.

Figure 2 is a rear elevational view of the buckle, with certain parts thereof broken away and in section.

Figure 3 is a transverse sectional view through the buckle, taken on the line 3-3 of Figure 1, looking in the direction of the arrows.

Figure 4 is a longitudinal sectional view through the buckle, taken on the line 4-4 of Figure 1, looking in the direction of the arrows, the view showing the jaws of the buckle in their partially opened position.

Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter B generally indicates my improved buckle.

One of the main uses of the buckle B is for adjustably connecting the strap of an overall to the body portion thereof, and, consequently, in Figure 1 I have shown the buckle applied to such a use. The shoulder strap is indicated by the reference character 5, and the buckle is adapted to engage the strap for detachably connecting the strap with a button 6 carried by a part of the front body portion 1 of the overall.

The buckle B includes a main body portion 10, and the same is preferably formed from a single strip of sheet metal bent upon itself to form longitudinally extending companion gripping jaws i I and I2. These jaws are resiliently connected at one end by a bowed resilient bight portion l3. The opposite ends of the jaws can be held toward one another in a clamping position in any preferred manner, such as by the use of a swinging bail 14. The outer end of the jaw II is rolled to provide a hinge barrel 15 for the bail i4, and the outer end of the jaw l2 can be provided with an outturned lip 16 over which the ball is adapted to be swung.

Formed on the longitudinal sides of the jaw I l are inwardly directed clamping flanges I1 and IS. The lower flange I8 has the central part thereof rolled to provide a hinge barrel 19 for receiving the upper end of a swinging loop 20, which is adapted to receive the button of the overall. Between the flanges I1 and I8 and on opposite sides of the longitudinal center, the jaw II has formed therein a pair of struck-in, spaced, parallel, clamping ribs 2| and 22.

The jaw 12 has formed on its longitudinal edges inwardly directed gripping flanges 23 and 24. Particular attention is directed to the fact that the flanges 23 and 24 lie within the flanges l1 and I8 and are out of longitudinal alinement with said flanges. A centrally disposed struck-in rib 25 is also formed on the'j-aw i2, and this rib 25 is adapted to extend between the ribs 2| and 22 of the jaw II.

In use of my fastener or buckle, the bail I4 is swung away from the spring tongue l6, and the buckle can now be slipped laterally on a strap in a selected adjusted position thereon. After the buckle is properly disposed on the strap, the jaws H and I2 are brought toward one another, and the bail i4 is swung over the tongue Hi. This will hold the jaws in clamping position on the strap, after which the loop 20 can be placed over a button.

By referring to Figure 3, it will be seen that the strap is firmly clamped at a plurality of spaced points, and that the strap is caused to take a tortuous path through the buckle when the buckle jaws are in their clamped position.

the strap is firmly gripped between the flanges l1 and 23 and the flanges 18 and 24. As the rib 25 lies between the ribs 2| and 22, the strap will 5 be firmly clamped between these three ribs.

In actual practice, it will be found that not only can the buckle be quickly placed on the strap at a selected point, but that the strap will be firmly gripped against slipping without danger 10 of tearing or puncturing the strap.

Attention is also called to the fact that while the hinge barrel I9 is rolled from a part of the' flange l8, said barrel actually forms a continuation of the flange I8, in that the barrel lies in is close proximity to the flange 24 of the jaw- 12 I when the jaws II and I2 are in their clamping position. a

Particular attention is directed to the swinga ing loop or hanger 20, as the same forms an 20 important part of my present invention. This hanger or loop 20 is formed from resilient material, and the legs thereof are normally urged toward the ends of the barrel I 9. It is also to be noted that the lower end of the hanger or 5 loop is provided with a restricted throat entrance for the button. During the placing of the loop on and oil the button, the legs of the loop spring outwardly to facilitate the movement of the button into and out of position. Obviously, when 30 the button is placed in position, the resiliency of the arms will prevent the accidental displacement of the button from the hanger or loop.

Changes in details may be made, which do not depart from the spirit and scope of my claims, and what I claim as new is:

1. A buckle comprising, a body including a pair of longitudinally extending jaws, means connecting the jaws together at one end, means detachably connecting the jaws together at their opposite ends, each of said jaws having inwardly directed gripping flanges formed on their side edges, the flanges on one jaw being out of Iongitudinal alinement with the flanges on the other jaw, whereby the flanges on the first jaw will lie inwardly of the flanges on the second-mentioned jaw, said jaws also having struck-in ribs arranged in staggered relation relative to one an- -other.

2. A buckle comprising, a body portion formed from a single sheet of resilient sheet metal including a pair of companion gripping jaws and a connecting bight portion, means detachably connecting the jaws at their outer ends, one of said jaws being provided with inwardly directed flanges, inwardly directed flanges formed on the longitudinal edges of the other jaw arranged out of longitudinal alinement with'the first-mentioned flanges for lying between said flanges, a pair of spaced struck-in ribs formed on one of the jaws between its flanges, and a single struckin rib formed on the other jaw between its flanges for movement between the first-mentioned ribs when the jaws are in their clamping position.

FRED BRAUN.
