H. F. GEORGE SAFETY BUCKLE Filed Feb. 22, 1945 2 Sheets-Sheet l I INVENTOR. BY (7%607? e Feb., 13, 1945. H. F. GEORGE SAFETY BUCKLE Filed Feb. 22, 1945 2 Sheets-Sheet 2 Patented Feb. 13, 1945 UNITED STATES PATENT OFFICE v t, T 2,369,225 r SAFETY'BUCKLE} Harry George, Chicago, Ill. 7 Application February 22, 1943, seria1 No. 476,612 f iclaims. (Cl. 24-193) This invention relates to a safety buckle, and more particularly to such buckle that will .be positive inits gripping action, is easy tooperate and one that may be quickly and easily released.

In buckle construction a heretofore practiced,

' it has been difiicult to tighten the straps to a desired degree of adjustment, or produce a sufiiciently positive grip for the straps, or quickly and easily release the buckle when speed in'such operation as required. I

, By the present invention I have produced a safety buckle havingthefabove advantages and overcoming the above difiiculties. Afurther object of myinventionis to provide a safety buckle not only adapted for general use, but especially adapted for use in aviators straps and belts, with positive holding. characteristics, and at the same time capable of instant release should such occasion arise.

Another object is to provide a buckle having part that may .be covered up for ornamental purposes, and be easily decorated by associated parts of a belt, strap or the like, or have decorations easily added thereto. A still further object is to produce a Jbuckle that is] sturdy in construction] economical to manufacture, and capable" ofbe'ing satisfactorily and efficien'tly made andus'edin, either large" or small size. y I w Another object is to provide a buckle which in use does n'ot'injure the material of the'belt or strap, does not require holes in the belt or strap, and does not cause fraying or undue wear therein. A further object is the provision of a buckle in which crimps are formed in the belt or strap, which crimps produce a positive gripping action,

Fig. 6 isa longitudinal, vertical section of a buckle with the parts in substantially 'the same position as in Figs. 3 and 5, and showing a porand which may alSo'be quickly and efiectively released. A still further objectis to provide such a construction that'to release the buckle all that is Fig. 1 is a perspective view 01' a safety buckle embodying my invention, and fragmentarily combina- 1 tion of the belt or strap in position therein and onlypartially crimped.. K

Fig. 7 is a view partly in longitudinal vertical section and partly in side elevation, with the buckle incompletely open position so that the belt orstrap may be quickly removed therefrom by a straight longitudinal pull. I

Fig. 8 is a view similar to Fig. 2, but showing a modified form of means for fastening the swinging arm to themain body portion.

, Fig.,9l is a fragmentary, vertical, transverse section through the fastening projection; and recess of the, form shown in Fig. 8, but with the parts in closedposition. I

.Fig. 10 is a perspective, sectional view, onf'an enlarged scale, of one of the crimping bars, i

Referring: indetail to the drawings, my new buckle isshown in Figs. 1 to '7 to comprises. main body'portion l and a pairof swinging arms} rigidly connected together by having at their larger end two symmetrically arranged. non-circular openings 3 and 4, separated by a cross bar 5', as

" seen in Fig. 3, there being inserted'in said..non-

circular openings (one ineach'lj-the correspondingly shaped ends 6 and! of the spaced apart

bars

8 and 9, the large ends of arms 2 being respectively fastened in place onthefen'ds of

bars

8 and 9 by cap disks lll secured tightly in placethereon by screws ll, which are screwed into threaded openings in the ends of bars 8'and 9 as the ends of the securely spacedapart bars 8 and 8 i sitie j has; i9 r9 messes...

bars

8 and 9;

In addition tothe side bars l2 the body portion I further comprises the plate l4, integral with the side bars or not, as desired. Secured to the rear end of. plate, 14 by'rivets or other suitable fastening means l5 are the two spaced flanges I6 and ll of the hollow cylinder 3, the open ends of vvhich-gylihderiare snuglypositioned in. side 'ofthe inner side faces of the large ends of side bars I2 as seen in Figs. 1, 2 and 5. It will be seen in Figs. 4, 5, 6 and '7 that the interiojr: diameter of cylinder I8 is larger than the exterior, diameter of the rigidly spaced bars 8 and '9 'byi' rwmchinstantly releases the toes 3'Lfrom pins 3| seen in Fig. 1.

Having described my invention, I claim: 1. In a buckle, in combination, a relatively stationary body portion having a non-rotatable hollow cylindrical member formed in its sides with oppositely positioned slots, a member rosaid body portion and having an elongated open-sided slot therein, an arm on each end of the rotatable member and fixed thereto to rotate said member, and a latch plate pivotally mounted at its ends to said arms, and a strap adapted to be freely passed through all of said'slots when the slots are in lateral registry and to be crimped when the slot of the rotatable member is out of lateral registry with the slots in the hollow cylindrical member.

2. In abuckle, in combination, a relatively stationary body portion having a non-rotatable hollow cylindrical memberformed in its sides with oppositely positioned solts, a member ro tatably mounted in said body portion and having an elongated open-sided slot therein, an arm on each end of the rotatable member and fixed thereto to rotate-said member, and a latch plate pivotally mounted at its ends to said arms, and means on said latch plate for releasably locking the arms to the body portion when the arms are moved thereagainst to crimp a strap passing to freely release the strap through said slot and when the strap is pulled laterally against the latch plate.

3. In a buckle adapted to releasably hold in adapted to receive therethrough a strap to be tightened position a belt, strap and the like, in
