WILLIAM K. PARKER, OF NEW HAVEN, CONNECTICUT, ASSIGEOR OF ONE- HALF TO ENGLISH & MERSICK, OF SAME PLACE.

CARRIAGE-BOOT- FLAP FASTENER.

' SPECIFICATION forming part of Letters Patent No. 268,723, dated December v5, 1882.

I Application filed October 19, 1882. (No model.)

.To all whom it may concern 'Be it known that I, WILLIAM K. PARKER, of New Haven, in the county of New Haven and State of Connecticut, have invented new Improvements in Carriage-Dash-Flap Fasteners; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in,-

Figure 1, a front view; Fig. 2, a vertical section, illustrating the operation of. the device Fig. 3, a side view; Figs. 4 and 5, perspective views of the two parts.

This invention relates to an improvement in clasps for securing the strap of carriageboot flaps, and particularly to that class in which a lever is attached to one strap and a frame to the other, the connection between the lever and its strap and the lever and the frame being such that the natural strain upon the strap serves to hold the clasp in its engaged position. Clasps of this class have been made in various constructions. Usually, the lever has been hinged to the frame, so as to pass through a loop on the other part of the strap, and then turned to its closed position, th'eloop engaging the lever. when in its closed position at a point inside the line of the pivot and the bearing of the point of the lever; but in'some cases the lever has been detached from the frame and hung to the strap by a loop, which would make a similar engagement when the lever was brought into connection with the strap and turned to its closed position; butin -all these constructions more or less mechanical work is required upon the clasp in its production.

The object of my invention is to constructa clasp in two parts, each detachable from the other, the one so as to be attached to one strap and the other to the other strap, and the two completed in the process of casting; and the invention consists in the construction of the clasp, as more fully hereinafter described, and particularly recited in the claim. The one part (shown detached in Fig. 4) consists of two sides, A'A, connected at their one end by a bar, B, which bar serves as a connection to one strap, C, as seen in Figs. 2 and 3. At the other end, and upon the inside of each side of the frame, is a trunnion, a, the space between the trunnions corresponding substantially to the 5 5 width of the second part, D, of the strap. The other part of the clasp (shown detached in Fig. 5) consists of two sides, E E, connected across one end by abar, F,and upon the inner surface of each side E is a projecting lug, I), made hook-shaped, as at at, corresponding to and so as to set upon respectively the two trunnions a a. A bar, 0, extends across between the two lugs 11 b and at a point distant from the inner surface of this part of the clasp 6 greater than thatof the hooks d, as more clearly seen in Fig. 2. This completes the article. These two parts are of such shape that they may be molded and cast complete and finished by the simple tumbling process, so that the cost of the article is only a question of weight,

no mechanical work being required.- The one part is attached to the one strap, C, by its bar B, as seen in Figs. 2 and 3, the other part attached to the other strap, 1), by the bar e. 7 When desired to clasp the two parts together, takehold of the part E E F and engage the hooks d with the trunnions a of the other part,

as seenin Fig. 2. Then turn the part E upward until its end strikes the strap above, as seen in Fig. 3. At this time the bar 0, which is attached to the other strap, has passed inside the line of the trunnion, asthere shown, so that the draft upon the strap D serves to hold the two parts in their closed condition. To disengage the two parts it is only necessary to turn the one part away from the other, as seen in Fig. 2. Then the hooks slip from the trunnions, and the flap will be free to he opened.

I claim-- 0 The herein-described carriage-boot-tlap fastener, the one part consisting of the two sides A A, connected at one end by a bar, 13, to which one strap is attached, and with the inwardly-projecting trunnions a a at the opposite 9 5 end, combined with the other part, consisting of the two sides E E, constructed with the hooks d d, to engage the trunnion of the other part, and with a transverse bar, 0, inside the line of bearingofthe hooks upon the trunnions, I00 and to which the other strap is attached, sub-= stantially as described.
