vEND-GATE FASTENER.

SPECIFICATION forming part of Letters Patent No. 726,148, dated-*April 21, 1903. Application led February 27, 1903. Serial No. 145,421. (YNojmodel.)

To a/ZZ whom it may concern:

Be it known that'I, WILBER R. DUNKEL, of the city of Pana, in the county of Christian and State of Illinois, have invented certain new and useful Improvements in End-Gate Fasteners, ofwhich t-he following is a specification.

This invention relates to end-gates formed of two pieces hinged together, one of the pieces being provided with a flap or extension and the other part being provided with a fastening to engage the flap and hold the pieces in line.

The invention is confined to the peculiar lconstruction of the fastening; and the object is to provide a simple and effective fastening that is easily manipulated and that Will'not' jar loose.

The invention is exemplified in the structure hereinafter described and it is defined in the appended claims.

In the drawings forming part of this specification, Figure l is a rear elevation of a wagon box, the end gate whereof is constructed in accordance -With my invention. Fig. 2 is a plan of the end-gate separate from the wagon-box. Fig. 3 is an end elevation of a fragmentof the wagon-box and end-gate, showing how the fastener holds the gate locked under unusual and. extremecircumstances. Fig. 4 isa rear Velevation showing a fragment of the wagon-box and end-gate, showing the fastener in position to release the flap and permit the removal of the end-gate from the box. g

The sides of the wagon-box are shown at 1 and 2. One piece of the end-gate is shown at 3, a liap or extension 4 is secured to piece 3, and piece 5 is secured to piece 3 by means of hinges 6. A metal plate `7v is attached to the extended ,endA of-flap 4 in any suitable manner, and a metal plate 8 is attached'to a Vcleat on piece 5 adjacent to the end of the Hap. The plate 8 has a -boss on which a fas'- ten'er 10 is pivoted, and a bolt 9 secures the fastener o n its pivot.. The fastener consists of the principal member 10, which is elongated and provided at its end with a lateral extension 11, a main lock extension 12, extending at approximate right angles with member 10, and an auxiliary lock extension 13 approximately in line with the principal member.

lock extension 12 extends across plate 7 and A A holds the pieces of the end-gate locked against swinging on hinges 6. When the wagon is loaded and there is pressure against the endgate, the friction developed by pressure of plate 7 against lock extension 12 will hold the fastener in place. When the Wagonbox is empty, the jar of the Wagon, particularly on rough roads, will tend to swing the fastenerv from side to side; Ordinarily the extension 12 will keep in engagement with plate 7 as' the fastener oscillates, and whenever the jar is sufficient to swing lock extension 12 from contact with the plate 7 the principal member 10 or the auxiliary lock extension 13 will engage plate 7 and hold the end-gate locked. Whenever the oscillation of the fastener becomes so violent as to throw the principal member 10 upward and past the pivot the auxiliary lock extension 13 will engage the plate 7-,- as-shown in Fig. 2, and prevent the gate from swinging open. In reaching the position shown in Fig. 3 the fastener must pass the opening position shown in Fig. 4, and to facilitate such passage a nose of lock extension 13 Vis turned slightly outward, as shown in'Fig. 2 and indicated by shaded lines in the other figures. This outward turn lforms an incline that permits extension 13 to ride freely over plate 7 and permits the Weighted end 11,.to pass the deadcenter before the gate has time to swing open.

The different parts maybe modified somewhat in form and proportio'nwithoutV departing from the principal of my invention, and the plates 7 and 8 may be secured in place by various mechanical oexpedients, so that I do not restrict myself to they details shown and described beyond the terms of the claims.

I claiml. The combination in an end-gate composed of two pieces hinged together and an overlapping lock-Hap on one of the pieces, of a fastener secured to the other piece of the end-gate adjacent to the end of the lock-Hap and composed of a principal weighted member, a main lock extension approximately at right angles with the main member and an 'auxiliary lock extension approximately in line with the main member, substantially as described.
