SPECIFICATION forming part of Letters Patent No. 280,592, dated July 3, 1883.
Application tiled April 17,'1883. (No model.)
i'afrtZZ whom it may concern:
Be it known that I, Aivros K. ERsLAND, of Sheldahl, in the county of Story and State of Iowa, have invented an Improvement in Platform Wagon and Gar Dumps, of whichthe following is a specification.
My invention relates specially to the wagondump for which Letters Patent No. 265,251 were issued to me by the United States October 3, 1882; and it consists in substituting two sliding track-supports for the suspended swinging supports, and combining them with a rock-shaft having cranks at its ends and a lever-handle between the cranks, in such a manner that the sliding supports will be locked under the ends of the pivoted track-rails by the closing of the trap-door, as required to keep the track-rails level, and simultaneously withdrawn'from under the track-rails by simply opening the trap-door and lifting the lever-handle attached to the rock-shaft, as hereinafter fully set forth.
Figure l of my accompanying drawings is a top view of my platform and dump, in which parts of the flooring are removed to show the sliding track-supports in their fixed bearings. Fig. 2 is a longitudinal sectional view, vshow,- ing a slidingtrack-supportlocked under the end of a pivoted track-rail. Fig; 3 is a longitudinal section, showing the trap-door open, the sliding track-support unlocked and withdrawn from under the end of the pivoted trackrail, as required to tilt the rail in dumping a load from awagon upon the platform. Jointly considered, these figures clearly illustrate the construction and operation of my complete improvement.
A are the side pieces, and B the end pieces, of the platform-frame. Y
'C G are pairs of joists fixed to the frame to support the flooring-plank.
D D are track-rails pivoted between the contiguous and parallel joists C. f f are metal bearers fixed to the side faces 'of the joists C, to retain the sliding track-sup ports level with the lower edges of the pivoted track-rails D.
g g are the sliding track-supports, extendling `horizontally across under the joists C, and v their ends through the bearers f. i
h is a rock-shaft supported in bearings fixed to the joists C at a point under the hinged edge of the trap-door. It has cranks h at its ends, and a lever, h, extending at right angles from its body.
are rigid .bars or rods fixed to the sliding tracksupports, and exibly connected with the cranks h. at their opposite ends, in such a manner that reciprocating sliding motions will beimparted to the track-supports g by the rocking motions of the shaft h.
m m are T-shaped latching devices, pivoted between the joists G in such positions relative to the sliding traclcsupports g that when these supports slide from under the ends of the pivoted track-rails D and allow them to descend the latches will, by force of gravity, drop and fasten the supports g, and thereby automatically lock the-rock-shaft h in its bearings, as clearly shown in Fig. 3, in such a manner that the lever h will y extend vertically to support the open trap-door and prevent it from being closed while a car or wagon is being unloaded, and when a car or wagon has been dumped and is moved forward on the track-rails the depressed ends of the track-rails will be elevated and the latches m lifted from the supports g by the upward motions of the ends of the trackrails, and the pressure of the trap-door upon the arm h of the shaft h will rock the shaft in such a manner that by means of its cranks h and the rods t' the sliding track-supports g will be pushed under the ends of the track-rails to retain them level with the platform, and the trap-door closed over the depressed arm or lever h will keep it down, and thetrack-sup ports practically locked thereby, so that they must remain under the ends of the pivoted track-rails as long as the trap-door remains closed.
I am aware that sliding bolts have been operated by means of pivoted levers to fasten and unfasten the ends of a suspended section of railway-track, but my manner of forming and combining sliding track-supports with the ends of a rock-shaft to simultaneously operate two pivoted track-rails in a platform and dump adapted for unloading wagons and driving over is novel and greatly advantageous.
I claim as my inventionl. In a platform wagon or car dump, the sliding track-supports g, in combination with IOO the rock-shaft 71, having cranksl/,substantially oted tl'zlekaails, and :L hinged tmpdoor 1'11 :L as and for the purposes shown und described. platform-dump, substantially as Shown :md de- 2.
