IMPROVEMENT IN SHIPPING AND UNSHIPPING HIND BOARDS T0 FREIGHT-WAGONS.

Specification forming part of Letters Patent No. 49,966, dated September 19, 1865; antedated August 31, 1865.

To all whom it may concern:

Be it known that I, FREDERICK W. BisHoP, of West Haven, in the county of New Haven and State ot' Connecticut, have invented a new and useful Improvement in Shipping and Unshipping the Hind or TailBoard of the Frame ofthe Box ot'F1eight-WagoIis, 85e.; and I do hereby declare that the following is a full, clear, and exact description ot the construction, character, and operation ot' the same, ret'- erence being had to the accompanying drawings, which make part of this speciiication, in which Y Figure l is a perspective View of the hind or rear portion ot' the frame ot a wagonvboX, showing the spring-bolts, spiral springs, &c., the top plate or band being removed for that purpose. Fig. 2 is a section of the saine, cut longitudinally and vertically through the frame ot' the hind board, &c., showing the relative positions of the springbolts, spiral springs, and the fitting ofthe upper corners.

My improvement consists in titting a pair of spring-bolts longitudinally into the upper rail ot' the frame ot' the hind board, with beveled outer ends, and the inner ends bent downward at right angles and extended a short dis tance below the rail, so that they may be read n ily taken hold of, both with the same hand,

and pressed together, so as to withdraw bot-h ofthe bolts, and thus release the fastening or unship the hind board; and in having a bowstrap of iron or other' suitable material attached to each end of the upper rail oi' the frame of the hind board, to pass onto the rear ends ot' the upper side rails of the frame to hold them from being sprung out by any accidental pressure, Sto.

I make all ot' the frame of the box in the usual way, as shown at A, &c., Fig. 1, except the upper rail ot the frame of the hind board. I make the upper rail, B, of the frame of the hind board with a longitudinal slot in the upper surface, as shown at a b, Fig. l. Into this slot I t two iron bolts, c and d, onto which I slip spiral springs, as e audf, and secure the inner ends ot' these bolts by means of two perforated iron nuts, g and 7L, embedded iu the slot, all as shown in Fig. l, and indicated in Fig. 2. I put metallic caps on the ends of this slotted rail B in the usual way, as shown at t1 andj, Fig. l, and indicated in section in Fig. 2. I also iit on two strap or loop bands, C and D, through which the rear ends ot' the two upper side rails pass, asshown at O and D, Fig. l, and indicated in section in Fig. 2, which will prevent the side rails from being sprung out so as to release the spring-bolts c and d when the wagon is loaded. I tit the spiral springs e and j' so that they will operate to shoot the bolts outward and into holes in the side rails, as shown at A A, Fig. 2, to lock or ship the hind board. Y

When I wish tonnship and let down the hind board, I take hold ofthe two inner ends ofthe spring-bolts where their bent ends project below the rail, as at m and n, Figs. l and 2, and press them toward each other until each of them strikes a pimp, or any other suitable stop, when the hind board may be let or turned down on the hinges E and F in the usual way; and when desired the hind board may be turned up to the position shown in Fig. l, when the spiral springs e andf will shoot the bolts c and d into the holes or spaces in or near the ends of the side rails, as indicated at A and A, Fig. 2, when the hind board will beproperly shipped or secured and ready for use.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

The combination of the spring-bolts c and d with the strap or loop bands C and D, when the whole is constructed, arranged, and fitted to produce the result substantially as herein described.

F. W. BISHOP.
