UNITED s'r rgas SLIDE BUCKLE.

Application filed April 3,

To all whom it may concern.-

Be it known that I, ARTHUR J. LEWIS, a citizen of the United States, residing at Strattord, county of Fairfield, State of Connecticut, have invented an Improvement in Slide Buckles, of which the following 1s a specification.

This invention relates to buckles and especially to'that type of buckle known as slide buckles used for adjusting the length of straps, webbing, and the like, such as suspenders, and is so constructed as to secure the strap in adjusted lengths without penetrating the material, and no stitching is required in attaching the buckle to the strap.

It is all obj eet of the invention to provide a buckle of this type which will securely hold the strap and not slip in operation when a strain is applied thereto, which is simple in construction comprising a single piece of wire, and which will be fiat and have no projecting portions to catch on articles of clothing or other elements when in use.

With these and other objects in view 1 have devised the improved buckle disclosed in the accompanying drawing, in which Fig. 1 is a plan view of the end portion of a suspender with the buckle in position.

Fig. 2 is a longitudinal, central section through the strap and buckle, as shown in Fig. 1.

Fig. 3 is a top plan view of the buckle detached.

Fig. 1 is an end view left of Fig. 3, and

Fig. 5 is an end view looking from the right of Fig. 3.

The strap 10 may be of any suitable material and is shown with its free end looped through the eye of a button-loop 11, and the body of the strap and the free end thereof are reeved through the buckle 12 in the manner shown in Figs. 1 and 2.

Buckle 12 is preferably made of a single piece of square wire as shown, although. round wire or other material may be employed, if desired. The square wire, however, has a somewhat better holding effect due to the comparatively sharp corners. The midlength of the wire is bent downwardly or ofiset, as shown at 13, a distance substantially equal to the thickness of the wire. The ends of the wire are then bent at right angles, as shown at 14, forming spaced parallel side members 15. The ends looking from the Specification of Letters Patent.

are then bent atright angles toward each,

other at 16 and then again at right angles to form the two immediate bars 17 closely adjacent each other and having theirfree' ends within the curve of the offset 13. It will be noted that the side members 15 and intermedlate bars 17 are all in the same plane. In fact, the whole buckle is in sub-.

stantially a single plane with the exception of the ofiset portion 13 and it, therefore, takes up very little room and. has no projectlng parts to catch on articles of clothing, and the like, when in use. This construction also gives two loops :tree at one endconnected at the other end by the bar having the offset 13.

The body of the strap 10 extends under the outer bars 15 through the loops and over the intermediate bars 17, as shown in Figs. 1 and 2, formin bends or bights there- I in which prevent sliding of the buckle under strain. The free end of the strap, after passing through the buckle 11, is extended upwardly intermediate the bars 17, bent upon itself around one of said bars beneath the body of the strap and under the adjacent side member 15. This member is securely held by the body of the strap and the intermediate bars understrain so that no stitching of the free end to the body is required and no sewing operation is necessary, thus decreasing the cost of assembling. l/Vhen strain is applied to the button-loop 11, the resulting pressing downwardly of the central bight 18 of the body member will grip the free end 19 more tightly between this bight and the intermediate bar 17 about which the strap is wrapped increasing the holding effect, and, pressing of the two bars 1'? against the inclined walls 20 of the offset 13, willalso tend to move the free ends of these bars together to more tightly grip the end of the strap.

It will be apparent this construction is very simple and, therefore, may be easily and cheaply manufactured." As all the side and intermediate bars are in a single plane, the buckle is fiat and has no projecting elements. Also that, through the peculiar construction pointed out, the strap is securely held with no liability of slipping under strain but still may be easily adjusted when required.

Having thus set forth the nature of my invention, what I claim is:

1. A slide buckle including a pair of loops having sidebars connected at one end and free at the opposite ends, intermediate bars extending from thefree ends to and over the connecting member, the side and inter-,

mediate bars being insubstantially thesaine plane, and the connecting member having its central portion oilset laterally from SQ-1d plane.

2. A slide buckle including a pair of loops hav1ng s1debarsconnected at one end'and free at the opposite ends which extend in- Wardly to form intermediate bars having" *thell freeends extendlng over the 'ing member, the 'slde and lntermediate bars connectbeing in substantially the same plane th e said connectingmemberbeing curvec l laterally from said plane betweenthe side mem-' "bets, and the free ends of the intermediate members contacting the inclined Wallsof said connecting member.

3. A slide buckle comprising spacedsubstantially parallelside bars and intermediate {bars betweenthe said side bars and in the antermediat'e bars.

4. A slide buckle comprising a single length of Wire bentat right angleson opposlte sides of itslzmidlength lZO fOIIH SHbstantially parallel spacedside bars, the free ends being then bent toward each other and the-n at right anglesto i-form intermediate bars between, substantially 'ipara-llel with and in substantially the same plane as the side bars,the'midlengthof the Wire between the side bars being offset laterally from the plane of the 'barsyandiathe firee ends ofnthe 1 intermediate bars 7 extending onnthe inner side of the oi'fsetp'o'ntion.

In testimony whereof I atfix my signature-.1
