HAME-FASTENER.

Specification of Letters Patent.

Patented July 7, 1914.

Application filed March 14,1911. Serial No. 614,505.

To all whom it may concern:

Be it known that I, FRED WV. COVERT, a citizen of the United States, residing at Watervliet, in the county of Albany and 'State of New York, have invented certain new and useful Improvements in Hame- F'asteners, of which the following is a specilication, reference being had therein tothe accompanying drawing.

This invention relates to hame-fasteners, the primary object being the provision of an improved type of fastener, neat in appearance, inexpensive to manufacture, eflicient in operation, and one which is durable and of increased strength.

In the art of hame-fasteners, it will be appreciated by those familiar with the same, that it has been found exceedingly difficult to entirely satisfy the trade with a fastener which will be of a compact form and neat in appearance, and at the same time of a strength to withstand the heavy strain imposed thereupon, and it is desired by the present invention to provide such a fastener, that is, one less bulky in design, relatively light, and one neat in appearance and exceedingly strong.

One of the important features of the invention resides in the provision of a main or body part of a boxlike construction, simple to manufacture and cheap to produce, and at the same time, permitting of a relatively thin or compact article, it being within the contemplation of the invention to provide a body part which may assume a position snugly about the collar and within the groove between the usual bead at the edge of the collar and the body part of the latter.

Also the invention includes an improved form or type of hook carried by and connected to the body part, one which is of considerable strength in its make up, and which is further strengthened and reinforced by the body part of the fastener.

Further the invention embraces an improved type of operating lever, and-associated link connections for the usual chain or flexible connection adapted to be coupled to the end of one of the hames.

Other improvements and the novel details in the construction and arrangement of parts, will be more particularly referred to hereinafter, and for a clear understanding of the invention reference should be had to the accompanying drawing, which form a part hereof, and wherein is disclosed, for the purpose of illustration, convenient and satisfactory embodiments of the invention.

In thedrawing: Figure 1 is a side View of one of the preferred formsof the fastener applied to a collar; Fig. 2 is a side view of the same separated from'the collar and with the locking lever in open position; Fig. 3 is an upper edge view; Fig. l is an enlarged elevation of the fastener with one of the side plates removed; Fig. 5 is a perspective view of the same; Fig. '6 is .an enlarged detail view of the lever showing the engaging-lip in position to be bent about thelink, and Figs. 7 and 8 are detail views of modified forms of links adapted to be connected with the lever.

With more particular reference to the drawing, in which like reference characters relate to corresponding parts throughout the several views, the main or body part of the fastener is made up of two side plates *1 conveniently of relatively thin substantially fiat metal, one edge of the body part being preferably slightly curved or segmental shaped as shown at 1*, while the opposite edge has a substantially U-shape cutout portion 1? intermediate of its ends constituting a recess or seat for a part of the operating lever to be described hereinafter.

A hook member is connected to one end of the body part and comprises a hook proper 2 conveniently curved as shown, and connecting with an extended upright part 8, and which said upright part is preferably an integral extension of the hook and is provided with a tongue or flange 4 adapted to fit between the side walls 1 of the body part. The hook may be and preferably is rigidly held in place on the body part by bolts or rivets '5 extending from side to side ofthe body part and through apertures in the tongue or flange 4.. The tongues is conveniently thin in cross section, say of substantially the same thickness as the side walls 1 of the bodypart, whereby, when in position the thickness of the body part is not materially increased by the interposition tion 3 of the hook member is preferably subiio- ' stantially of the same width as the 'body' part as a whole, and extends from top to bottom thereof, and fits flat against the ends of the saidwalls 1 of the body part,

which said end wall is shown slightly in-.

clined upwardly and inwardly toward the body part, the parts being constructed and arranged so that when the fastener is upon the collar and the device is inoperation, the strain upon the hook proper is resisted by the upright wall 3 from top to bottom, which latter is reinforced in turn by the backing afforded by'the ends ofthe said walls 1 of the body part. Again the strength of thehook is further increased by the tongue or flange 4, which it will be noted extends substantially at right angles to. the plane of the upright wall 3 of the hook. This type of hook forms a very rigid construction of strength and durability and being an independent element is easily and cheaply produced. 7 Also this independent construction of the hook makes possible the box-like type of body part, and reduces the cost of production of the later, since the side .wall. construction of the body part results in a reduction of the, amount of metal consumed, with the incident saving of expense and reduction in weight, and further the side walls' can be, cheaply and readily stamped into the required shape. Conveniently a relativelysmall spacing block 6 is positioned between what may be termed the rear ends of .the walls of the body part adjacent the upper edges of the latter the spacing block being held in position by a rivet 7 or the like.

The operating lever is conveniently formed with a handle part 8 shaped to conform tothe curvature of the forward lower edge of the body part and the hook, and projects beyond the latter. relatively flat so asto snuglv fit against the adjacent parts of the body part and hook when in locking position and the projecting end is slightly curved as shown in the gen: eral direction ofthe hook.

Thelever has a thickened portion 9 adj a'cent the rear end thereof, which thickened portion connects'with the forward end of a I relative thin tongue or projection 10 eX-,

I tending at substantially right angles to the plane of the handle part and of a width to loosely. engage between the side walls of the body part. Projecting through the side Walls 1 adjaeent'the lower rear end of the .latter is a pintle ll, and the tongue end 10 of the operating lever has an aperture 11 adapted toloosely'engage over the pintlc, whereby the lever as a whole is pivotally mounted on the body part. The thickened portion 9 of thelever has an inwardly extending tail piece 12 conveniently of the same width as the handle portion of the le- The handle isve'r, which said lip or tail piece is of bendable metal. Adapted to be connected to the lever is a'link member preferablyc'ompri'sing two stamped out sides'13 and an end bar 1 lt. The sides 13 preferably bulge as shown so as to readily pass over the pivotal bearing or support 11, and the securing means for the spacing block 6, while the forward end bar 14- of the link is conveniently round in cross section and is adapted to be pivotally supported on the lever, by exerting pressure on the yieldable'or bendable lip or tail 12, and bending the latter aboutsaid end bar 14, so as to form a substantially closed though loose bearing for said link.

'14 of the link will lie within the U-shaped recess l of the body part, the base of which constitutesv a seat, and the opposite sides of which recess are conveniently inclined to permit of the ready engagement and release o-f'the lever from said recess.

One end ofthe link is open, the opposite sidesofwhich linkadjacent said end being apertured for the reception of an auxiliary link having a closed end 15 andinwardly converging sides 16which latter have 'oflset terminals 17, adapted to'engage the aper tures in the sides 13 of the first mentioned link. The ends of said offset portions 17 maybe upsetto the outside of the side 13 of the first mentioned link, whereby to hold the link against separation. Conveniently the auxiliary link just described maybe formed of a piece of wirebentupon itself to 'a substantially U-shaped formation, with the offset terminals, which latter may be sprung into. place inthe apertures in the: sidesof' the connected link. The auxiliary link is movable abo-utthe pivot formed by said offset terminals, which loo-sely fit in the apertures provided in the sides of the connected link, whereby the respective link members together constitute a flexible con-v nection which will more readily conform to the curvature of the collar. Theconverging sides of theauxiliary link also prevent the chain 18 which is connected thereto from passing into the main link, or between the sides of the main link and the body part'of the fastener, or otherwise interfering with thefreeoperation ofthe parts. The chain conveniently has an adjustable connection or coupling 19 with the end of one of the hames.

In normal or operative posit-ionthe fastener will assume a position such as illus-[ trated in Fig. 1, in which said figure, A is a section-of a collar, the same having a beaded edge ajformiing a groove a between said edge and the body portion of the collar. Because of the box like structure and I relatively flat makeup of the main or body part of the fastener, the same may assume a position within the groove a of the collar with the curved. or concave edge 1 of the body part snugly fitting against the base of said groove. The flexible construct-ion afforded by the links which are connected to the lever, permits the link to engage about the collar, asmore clearly illustrated in Fig. 1. To release the parts the operator grasps the projecting end of the lever as is obvious and imparts downward movement thereto, when the lever will swing about its pivot and the various parts will assume a position more clearly illustrated in Fig. 2, and when the hook 2 may be readily disengaged from the end of the hame.

In Fig. 7 is disclosed a slightly modified form of flexible link connection between the lever and chain and in said figure the main link has a closedend 20 connected to the lever as desired and oppositely disposed sides 21, which converge at their ends as shown leaving a space therebetween for the reception of a collar 22 of an auxiliary closed link 23, which latter is adapted for connection with the chain. A bearing 24 conveniently having upset ends passes through apertures in the-ends of the sides 21 of the link, and through the collar 22 of the auxiliary link, the bearing constituting a loose support for the auxiliary link. From this illustration it is obvious that theconnected links may take various forms, such for instance as further illustrated in Fig. 8 in which the sides 21 and closed end bar 20 are provided as before. The auxiliary link 21 in this form is substantially U-shaped and the arms thereof having apertures adapted to register with apertures in the sides 21 of the first mentioned link. A. bar or rivet 21 loosely passing through said registering apertures and conveniently offset at its ends forms a pivotal connection between the links.

In each of the above forms it will be appreciated that the flexible character of the link connections permits a neater fit about the collar and at the same time the chain is held from interference with the parts when in operation.
