Patented Feb. 21, 1933 BOSQUE M. WI-II'IEKER, 0F HASKELIi, TEXAS BUCKLE OR FASTENER Application ffiled n'ecember. 12, 1930 Serial No. 501,753.

This invention relatesto'buckles or fasteners for the purpose of securingany suitably flexible strap, such as acanvas strap or the like, to any similarlyfiexible object or article, such as a canvas sack or the like.

The principal objects of the invention are to simplify and render more efficientthe art involved, to provide a fastener with features of adjustment not possessed by any known form of buckle or fastener, to provide a fastener which will not tear the fabric engaged, to provide a buckleror fastener consisting of only two main elements, one a freellock pin for removablyenfolding in the doubled fabric of the sack or the like at any desired point thereupon, as in the hem of the m rgin of the mouth of the sack, and the other, a slotted frame or anchor element which may be constructed in several forms, each adapted to slidably engage the said lock pin and the enfolding fabric of the sack as well as the additional and superimposed fold or loop of the strap laid over the said'lock pin and sack fabric, in such manner as to un-. yieldingly tie or look thevstrap to the sack. In addition to the lock pin and anchor plate as constituting the two main elements of the invention, there is also provided. an auxiliary slotted key for use in conjunction with the lock pin andanchor plate for providing a particularly strong or secured connection between the strap and the sack, or whatever the connected flexible articles may comprise In the following specification, the invention will be described as for connecting a flexible canvas strap to a canvas sack but it will be understood, of course,-tha,t the invention may be applied and used for any similar purpose, or where it is requiredto join together any two suitably flexible articles.

i In carrying out my invention, I provide a lock 'pin lasshown in Figure 3, several forms of anchor element or frame, as shown at 2, 8, land 5 in Figures 5, 7, 10 and 13 respectively, and akey' 6, asshfown in Figure 8. These elements maybe constructed of any suitably rigid material, such asmetal. The pin maybe constructed of heavy'wire, or wood or heavy cord, or any other suitablematerial and the anchor-element and key. of

sheet metal, or fibre or bakelite or other suit length of the able material. The anchor element or frame 2, in Figure 5, is formed with a longitudinally extended main slot 7 of a length slightly shorter and width somewhat greater than the length and diameter of the pin 1, so as to permit the latter to easily pass through the former, and the slot 7 is extended and narrowed at its ends as shown at 8, to provide a sort of bearing for the ends ofthe pin 1 after same is passed through the slot 7. In the application of the elements of the invention as so far described, two of the lock pins 1 are loosely inserted within the hem 9 of the mouth of the sack' '10, which may be done in the making of the sack or otherwise.

These pins are then adjusted to opposite sides of the mouth .of the sack which may be readily done. i

A pin 1 is then passed through the slot 7 of an anchor element or frame 2, the said slot being just wide enough to snugly pass the pin carrying its fold or hem 9 of material as stated. By then pressing the frame 2 down somewhat below the pin 1 so as to space the two sufliciently apart, an end 11 of the strap 12 may be readily worked up through the slot 7 and narrowed ends 8 from the outer side of the sack 10, up over the pin 1 and then down again through the slot .7 and narrowed ends 8 at the inner side of the sack. A pull upon the strap 12 will now draw theassembly taut, with the pin 1 bearing upon the frame 2 and the folds of material pinched between the two, this pinching effect being especially effected at the narrowed slot ends 8, so as to firmly secure the strap to the sack. This operation may be repeated at the opposite side of the sack for locking the other end of the strap to the similar pin 1 at that side, whereby a perfect loop (not shown) is provided for supporting the sack from the shoulder, or for such other purpose as may be desired. The width of the strap 12 should correspond to the length of the slot 7 and extensions 8. For the sake of strengthening the frame 2, the margins thereof may be flanged up as shown at 13. The fastening elements as just described and assembled will suflice for all ordinary connections, but if an especially strong connection is desired, for unusually heavy service, I provide in addition, an auxiliary or reinforcing key 6, which is'in the form of a fork embodying the prongs 1 1 spaced apart to provide an open slot 15 corresponding in width to that ofthe end slots 8 of the frame 2, and the width and prongs 14 corresponding vto the space within the flanged sides of the frame 2 so that-the key may seat therein with the

slots

7,8 and 15 in registry. The key 6 is mounted in place'by passing the prongs 14 over the aggregated folds of the hem 9 and strap 12 surrounding the pin 1, the said prongs passing between the pin 1 which thus is enabled to prongs 21 and through in Figure 9. This key thus mounted serves as a reinforcement against lateral strains.

In order to facilitate mounting the frame or anchor element 2 upon the hem of the sack, over the pin 1, the end flanges 13 thereof maybe undercut as shown at 16, in alignment with the slot 7 and extensions 8, for the accommodation of the top of the hem 9 pass straightly and smoothly out past the ends of the pin 1, without crumpling. The form of fastener as described provides a very simple, eflicient and practical means for securing the strap to the sack, and eliminates any danger of tearing the fabric of the sack, as the grip afforded is in the nature of a purely friction grip and teeth are eliminated. As suggested above, the lock pins 1 may he slid through the hem to any desired 1 point around the mouth of the sack.

- Instead of the hem 9, the fabric 17 may be simply folded over the lock pin 1, as shown in Figure 4. When the strap and frame are then assembled thereover as already described, the joint will be firmly locked together. Where it is desirable to connect a rope or cable to any form of fabric, as to an awning (not shown), a special form of frame or anchor element 18 may be employed, as shown in Figure 12, the said frame having an aperture 19 cut through it for the reception of a rope (not shown).

Another modified form of frame or anchor element is shown at 3 in Figure 7, wherein the main slot 7a is enlarged at one end as shown at 20, to facilitate the pass ing of this form of frame over the pin 1. In such case the main slot 7a may be narrowed less than the diameter of the pin 1, inasmuch as the pin is passed entirely through the opening 20. Another modified form of frame is shown at 4 in Figure 10, wherein the frame is formed like a fork, similarly to the key 6, there being thus provided an open slot 76 and the prongs 21 which are adapted to approximately register with the prongs 14 of the key 6. In this case the ends of the prongs 21 carry out turned ears 22 spaced from the prongs, thereby forming slideways 23 adapted vto slidably engage the prongs 14. In the use of this form of frame, the frame itself may be slid into place beneath the pin 1 in the hem 9 and over the superimposed loop of the strap 12, the fabric passing into the open slot 7?), and the key 6 may be then slid into position upon the frame, entering at the extremities of the the slideways 23, thus looking all together.

Stillanother form of frameis shown at 5. in Figure 13, the same consisting of an opentube, longitudinally slotted as shown very satisfactory,

' having a slot through which ing the same together,

at 70, whereby the slid into place over the lock pin and fabric folds in the manner and for the purpose as previously described. In this form the ends of the tube would be turned inwardly as shown at 24, for the sake of strengthening the structure.

As stated, the several fastening elements may be made of any suitable material, and the dimensions, gage and strength of material may be selected as desired. In actual practice, lock pins 1 of Number 9 wire, United States standard gage, cut in lengths of two and three-fourths inches, have been the slots and other features of the anchor elements or frames being formed to correspond, of course. 01' in lieu of lock pins, sacks having enlarged marginal edges or seams may be employed, the same being in cross section substantially equal to that of the lock pins and serving the same purpose. These marginal enlargements may be produced in any desired manner, as by rolling the marginal fabric back upon itself and sewing it down to form a hem 25 as shown in Figure 15, and as more particularly pointed out in a separate application to be shortly filed.

From the foregoing description, it is thought the method of construction and manner of use of the invention will be fully understood, and while I have herein pointed out certain specific forms and features of certain embodiments of my invention, it is understood that I may vary the same or adopt new forms, within the scope of the appended claims.
