FRANK'V. MIX, OF NEW BRITAIN, CONNECTICUT. I,

TRUNK R Box FASTENER.

SPECIFICATION forming part of Letters Patent No. 355,333, dated January 4, 1887.

Application filed September 28, 1886. Serial No. 214,748. (No model.)

T0 all whom, it may concern.-

Be itknown that I, FRANK W. MIX, of New Britain, in the county of Hartford and Stat-c of Connecticut, have invented certain new anduseful Improvements in Trunk or Box Fasteners, 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. Y

My invention relates to an improvement in i trunk-fasteners, and especially 'to the type of trunkLfastener patented to H. A. Seymour, August 4, 1885, No. 323,830.

The object of the invention is to provide a trunkfastener in which a loop may be actuated by a lever in locking Yand unlocking the fastener, the parts to be so combined and arranged that the loop cannot be accidentally displaced or unlocked.

A further object is to produce atrunk-fastener which shall be simple and durable in its construction and adapted to be manufactured at a small initial cost.

Vith these endsv in view my invention consists in certain features of construction and combination of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure lis a plan View of one form of my improved trunk or box fastener in its locked position. Fig. 2 is a plan view showing the fastener in an unlocked position. Fig. 3 is a rear face view of the device. Fig. l tis a longitudinal section of the attached parts, showing the saine in their locked position. Fig. 5 is a longitudinal section showing the parts in their unlocked position. Fig. 6 is an enlarged view ofthe calnlever, showing the manner of its attachment to the lower bar of the swinging loop. Fig. 7 shows the yielding slidebar removed from its position on the rear face of the top plate.

A represents a plate constructed to be secured to the front vertical face of a trunk-lid, and B a plate adapted to be secured to the body of the trunk in a line with the plate A on the lid. Plate B is formed witharecessed projection, a, the upper end of which is pro vided with parallel rearwardly projecting llanges b, that together form asocket, b', which is designed to receive the dowel c,that is on the lower face of plate A. The dowel c is rounded on its free end to permit its ready engagement with the receivingsocket b.

l C is a cam-lever pivoted in the lower portion of the recessed projection a. The walls of the projection c have rounded projections made on their front face, and seats 7c on their inner surfaces, forming bearings for the trunnions o, which latter are preferably cast Aintegral with the lever C. The cam-lever Cis retained in a vertically-swinging connection within these bearings by the holder d. (See Figs. 4 and 5.)

This holder is made to till the recessed projection c edgewise, one end being riveted tothe rear side of the fastening-plate B, while the other end is provided with a lip, Z, which rests on the outer surface of the vertical plate within the groove m. Holder el extends forward a proper distance to afford an abutment or bearing for the rounded boss e on the cam-lever C, and thus permit its swinging movement. and retain it in place. This manner of connection is cheap and strong in construction and reliable in operation.

D is a loop or rectangular link -having parallel top and bottom bars g1g. The lower cross-bar, g', is provided with a round bearing, g2, which is supported in a seat, g3, formed in the lever C, which latter part is bent so that the lower bar, g', ofthe loop D will be retainedin contact with the lower wall of the box a when vthe loop D is in itslocked position. The

free end of the cam-lever C is adapted to lie in a groove, m, in the plate B, made for its reception, so as to be flush with the exposed face of j lower cross-bar, g', of loop D. This lip t is of proper length to be bent around the journalv g2, and thus pivotally connect the loop to the lever.

The upper plate, A, is constructed with a box or recessed projectiomwt, that extends outwardlyr from its front face, the front wall of said box being made to extend upwardly to roo form a lip, J. A yielding slide-bar, G, is connected with the rear side of plate A,`the upper end of such bar being provided'with a slot, c', within which engages a projecting stud on plate A, and thus retains the upper end of the bar G against lateral displacement.

rlhe lower end of the yielding bar G is provided with ashank,S,which hasa spiral spring, s, placed on it. This spring has a bearing upon the `shoulder, formed by reducing the bar G, to form the shank, and it, as well as the lower end of the shank, is supported by a lip, s, cast integral with the plate A and bent round to forni a box-bearing of proper size to permit the sliding therein of the shank s and consequent vertical movement of the bar G. The yielding slide-bar G is provided on its front face with a shouldered projection, I,`

which extends within the recess or space in rear of lip J and is located below the upper edge of the lip. rlhe length of the loop D is proportioned to permit its upper cross-bar to be raised above the upper edge of the lip J by elevating the cam-lever C so that the upper cross-bar of the swinging loop D will engage the projection I on theyielding bar G, when the cam lever C is depressed to lock the fastener.

It is evident that a depression of the lever C will cause the loop D to bear upon and correspondingly depress projection I and its supporting slide-bar G. rlhe force of the spring 8 on the yielding bar G tends to force the loop D in an upward direction, and thereby serves to prevent the cam-lever fro'm swinging outwardly and carry the pivotal bearing of the loop past the journaled center of the cani-lever C, and in this way obviates danger of accidental displacement of the lever or loop.

It'is evident that slight changes might be made in the construction and relative arrangement of the different parts of the fastener without departing from the spirit or scope of my invention; and I do not limit myself to the precise construction and arrangement of parts shown and described; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a trunk or box fastener, the combination, with atop and bottom plate provided with doWel-and-socket connection, the top plate having a projecting lip formed thereon, of a swinging loop, a lever for actuating the loop, and a yielding bearing or projection located in rear of the lip on the top plate, substantially as set forth.

2. In a trunk or box fastener, the combination, with a top and bottom plate, of a swinging loop, a lever for actuating the loop, and a yielding bar located in a recess in the rear surface of the top plate, said bar being provided with a projection with which engages the cross-bar on the free end of the swinging loop, substantially as set forth.

3. In a trunk or box fastener, the upper plate havinga projection cast integral therewith and bent to form a bearing, incombination with a reciprocating bar provided with a shank that is retained within said bearing, substantially as set forth.

4. In a box or trunk-fastener, the combination, with a swinging loop, of a lever having a projection cast integral therewith and bent over to form a bearing within which the crossbar of the loop is pivotally secured, substantially as set forth.

5. In a trunk or box fastener, the combination, with a leverjournaled in bearings in the rear side of the plate, ot a holder secured at its ends to the plate and adapted to prevent the displacement of the lever, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

FRANK W. MIX.
