ARTHUR E. CLARK, OF VILLARD, MINNESOTA.

BUCKLE.

Specification of Letters Patent.

Patented Feb. 3, 1914.

Application led April 1, 1912. Serial No. 687,918.

To all whom t may concern Be it known that I, ARTHUR E. CLARK, a citizen of the United States, residing at Villard, in the county of Pope and State of Minnesota, have invented certain new and useful Improvements in Buckles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved buckle especially adapted for use on harnesses, and to this end, it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

rlhe improved buckle, as illustrated, is designed for use in connecting a harness tug to the hame strap, and is provided with a pair of tug engaging tongues, set one in advance of the other, thereby greatly increasing the strength of the tug.

The improved buckle is also so designed that a strap may be applied thereto, or removed therefrom, without bending the strap, thereby making it extremely easy to operate and, at the same time, avoiding cracking the tug. Owing to the particular shape of the buckle., the attached straps can be considerably less in lengt-h than would be required if an ordinary buckle were used.

The invention is illustrated in the accompanying drawings wherein like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a plan view of the improved buckle, having attached thereto a portion of a harness; Fig. 2 is a longitudinal section, on an enlarged scale, taken on the line m2 m2 of Fig. l; Fig. 3 is a view in side elevation showing the improved buckle in an open position, with some parts broken away and some of the exposed parts shown in section; and Fig. '-1 is a detail view in transverse section, taken on the line fc4 x4 of Fig. 2.

The numeral 1 indicates the body portion of the improved buckle, which, as shown, is channel shaped in cross section. At their forward ends, the Hang-es 2 are extended beyond the web portion of the body member 1, and a transversely extended hinge pin 3 is rigidly secured at its ends, to the extended ends of the flanges 2. Extending rearwardly from the body member 1 and integrally formed therewith, is a pair of lugs et that extend in the same plane with the side flanges '2, but project from the opposite side of the body member 1. A transversely extended pin 5 is rigidly secured, at its end, to the lugs 11. Pivotally mounted on the pin 5 for a limited swinging movement, is a U-shaped strap retaining loop 6.

Connected to the hinge pin 3 for a limited sliding movement and a hinge-like movement, is a tongue carrying member T, which is also channel shaped in cross section and is inverted with respect to the body member 1. The web portion of the member 7 is extended forwardly beyond the side flanges 8, and is bent upon itself to form a longitudinally extended loop 9 that loosely embraces the hinge pin 3 with freedom for a limited sliding movement and a hinge-like movement,

Integrally formed with the web portion of the member 7, is a pair of straight parallel tongues 10, that are spaced one in advance of the other. These tongues 10 extend between the side flanges 8 and are located intermediately therebetween. lVhen the tongue carrying member 7 is in a closed position, its side flanges 8 loosely fit between the flanges 2 and rest upon the web portion of the body member 1. The side flanges 8 support the tongue carrying member T above the body member 1 to afford a strap passage 11. The tongues l0 are of'such length, when in a closed position, to extend through an alined pair of longitudinally extended slots 12 cut in the web portion of the body member 1.

A pair of cam lugs 13 having lock flanges 14e are integrally formed, on the inner face of each of the flanges 2. The look flanges 14 extend parallel to the flanges 2 and are spaced apart therefrom by means of the cam lugs 13. These lock flanges 14 also extend inward from the cam lugs 13 and terminate at their inner edges in cam surfaces 15. On the outer face of each of the flanges 8, is integrally formed a pair of lugs 16, having cam shoulders 17 and lock flanges 18. rIhe lock flanges 18 extend parallel to the flanges 8 and are spaced apart therefrom by means of the lugs 16. These lock flanges 18 extend upward from the lugs 16 and terminate, at their upper edges, in cam surfaces 19. The lock flanges 14 and the lock flanges 18, have interlocking engagement by a sliding movement and hold the body member 1 and the tongue carrying member 7 against lateral movements in respect to each other. The cam shoulders 17 cooperate with the cam surfaces and the cam surfaces 19 coperate with the cam lugs 13 to draw the t-ongue carrying member 7 onto the body member 1. In this position of the member 7 the tongues 10 are seated in the slots 12.

Secured to the pin 5 by sewing or otherwise, is a hame strap Q0. Adjustably connected to the hame strap 20 by the improved buckle, is a tup 21 having its inner end eX- tended through the strap passage 11, and provided with a multiplicity of' longitudinally spaced holes 22, through which the tongues 20 are adapted to project. On the outer faces of the side lianges 2, is rigidly secured a pair of oppositely projecting strap receiving loops Q3. To one of the loops 23, is secured a back strap 24 and to the other of said loops is secured a belly band 25.

To apply the tug 21 to the improved buckle, its inner end is first passed under the hinge pin 3 through the passage 1.1 and through the loop G. The tongue carrying member 7 is then swung downward on the hinge pin 3 and the tongues 10, carried thereby, are passed through one of the sets of holes 22 formed in the tug 21. Then, by pulling on the tug 21 in a direction from the improved buckle, the tongue carrying member 7 is slid on the body member '1 and hinge pin 3 until stopped by the tongues 10 engaging the outer end portion of the slots 12. At the limit of the sliding movement of' the member 7, the rear end of' the loop 9 is engaged by the hinge pin 3, the lock flanges la and 18 are interlocked, one with the other, the cam surfaces 19 brought into engagement with the cam lugs 13, and the cam surfaces 17 brought into engagement with the cam surfaces 15.

wWhat I claim is:

1. A buckle comprising a pair of' coperating channel shape members inverted one in respect to the other and connected by a sliding hinge joint, the flanges of said members being interlapped and alfording a strap passage, a tongue secured to one of said members and projecting into said strap pas sage, and laterally project-ing cooperating pairs of cam lugs on said flanges, arrangei'l to draw said members toward each other under the pulling stra-in ot' straps attached thereto.

A buckle comprising a pair of coperat ing channel shape members inverted one in respect to the other and connected by a sliding hinge joint, the flanges of said members being' interlapped and abi'diiig a strap passage, a tongue secured to one of' said members and projecting into said strap passage, and laterally projecting cooperating pairs of cam lugs on said flanges, the members of each pair of cam lugs having both longitudinal and lateral interlocking engagement7 and arranged to draw said channel shape members toward each other under the pulling strain of straps attached thereto.

ln testimony whereof I aflix my signature in presence of two witnesses.
