UNITED STATES PATENT OFFICE.
JOHN PLAYER, OF TOPEKA, KANSAS.
DUMPlNG-CAR.
SPECIFICATION forming part of Letters Patent No. 483,790, dated October 4, 1892.
Application filed May 6,1892- Serial No. 432,029. (No model.)
To all whom, it may concern.-
Be it known that I, JOHN PLAYER, a citizen of the United States, residing at Topeka, Shawnee county, Kansas, have invented a certain new and useful Improvement in Dumping-Oars,of which the following is a specification.
This invention relates to dumpingcars, which, as is well known, are cars provided with doors opening at the sides, through which the contents of the car are discharged, whence the name dumping-car. These doors are made either one door at either side of the car, extending along its entire length,or two or any other number of doors at each side, as may be desired. Some means for readily locking and unlocking these doors is desirable; and the object of my invention is to provide a device adapted for such purpose,which device, speaking in general terms, consists in a bar adapted to be moved both horizontally and Vertically to be'brought into engagement with and disengaged from the door or an attachment thereto.
. My invention consists in the features, details of construction, and combinations hereinafter described and claimed.
In the drawings, Figure 1 is a side elevation of a dumping-car provided with my improved locking-bar; Fig. 2, a crosssection on line 2 of Fig. 1, looking in the direction of the arrow; and Figs. 3 and 4, details of parts of the device, the last three figures being upon an enlarged scale.
The car A, which is shown in the drawings without its trucks and wheels, is made of the usual form and dimensions and is provided with a bottom B, sloping both ways from the center line of the car, in order to direct the contents of the car to either side thereof, though of course my device could be used with a car the bottom of which did not slope, as shown.
Hinged at either side of the car is a door 0, and, as already stated, there may be one of these doors at either side of the car or a greater number, as desired. When the car is divided in two at its longitudinal center by a transverse partition, as is often the case, there would then preferably be two doors at each side of the car, extending from the ends of the car and meeting at a point opposite this transverse partition. These doors are supported by strap-hinges D, as shown, the lower ends of the straps extending down below the door, as shown at d, and being slotted, as shown at d, Fig. 3, for the purpose hereinafter described. Attached to the car at points preferably opposite these straps are hooks E, (shown more particularly in Fig. 4,) the slots d in the straps being provided for the purpose of allowing these straps to pass over the hooks, as shown at the left-hand side of Flg. 2. One or more bars F, of any suitable material and dimensions, are supported at either side of the car by means of the links F ,whereby the bar is enabled to move somewhat 1n the manner of one member of a parallel ruler. A lever G is provided at the end of the car for the purpose of operating this rod, moving it back and forth. When there 1s a SIR- gle door at either side of the car, there may be but a single bar. When there are two doors, there will be two bars along each s1de of the car, there being in that case a lever G at each end and at each side of the car, or four levers in all.
The device operates as follows: When the door is closed, the locking-bar is rocked toward the right, Fig. 1, by means of its lever. Owing to the manner of attachment to the car, the bar will not only move toward the right, but will rise and pass in between the hooks E and the lower ends of the straps D,
as shown at the left hand of Fig. 2, locking the door. To unlock the door, the bar will be moved in the opposite direction, when 1t will fall below the lower ends of the straps, as shown at the right hand of Fig. 2, allowlng the door to open. By this means I provlde a simple and efficient device for readily and quickly locking and unlocking the door which can be operated from the end of the car with out its being necessary to get in the way of the door to unlock it; and while I have shown a somewhat precise form, I do not intend to unduly limit myself thereto, but contemplate changes in form, proportion, and the subst1- tution of equivalent members, as may be desirable or necessary. For example, instead of having the straps D extend below the door, as shown at d, the door can be provided with lugs or extensions of suitable shape to be engaged by the locking-bar, and the ends of the straps or the logs or extensions may be placed directly opposite the hooks E or not, so long as such extensions and lugs are so placed that when the bar is raised it shall pass between them to lock the door, as shown at the left hand of Fig. 2.
I claim-- 1. In a dumping-car, a locking-bar pivotally attached to the car and adapted to move longitudinally and in a vertical plane to lock and unlock the door, substantially as described.
2. A dumping-car provided with swinging doors, in combination with a locking-bar pivoted to the car and adapted to move longitudinally and in a vertical plane to engage JOHN PLAYER.
