SEL'F DISCHARGING CAR. APPLICATION FILED FEB- 9, 1921.

SELF-DISCI-IARGING CAB.
Application filed February 9, 1921.
T 0 all whom it may concern:
Be it known that I, RUDOLF Lonnnz, residing at Essen, Germany, a citizen of the German Republic, have invented a certain new and useful Improvement in Self-Dis charging Cars, of which the following is a specification.
This invention relates to self-discharging cars discharging from the bottom and having bottom flaps opening automatically under the weight of the load and m vable side walls resting with their lower edges upon the bottom flaps and being displaced by the latter on the discharging operation and pivoted at their upper edges on fixed parts of the car. The object of the present invention is to so improve self-discharging cars of the type described as to enable a quick and reliable discharging even in the case of extremely bulky material to be discharged. i
One embodiment of the subject-matter of the present invention is illustrated in the accompanying drawing in which- Fig. 1 shows a section through a self-discharging car constructed in accordance with the invention, ready for loading, and
Fig. 2 shows a similar sect-ion ot' the car in the discharged state.
The two bottom flaps B are connected, so as to admit of rotation, with the undertrame A of the car by means of bearings a arranged at either side of the longitudinal middle plane of the car. The bottom flaps B are inclined toward the middle line where their respective lower edges 72 bear against each other and they thus constitute a tunnel.- shaped hold. The two side walls C are sus' pended at their upper edges by means of hinges c to the stationary end walls A? ot the car, their lower edges 0 resting on the bottom flaps B. The conditions and respective dimensions are so chosen, that the lower edge 0 of each side wall will, at any position which the parts may assume, be disposed nearer to the middle line of the car than the bearings a of the bottom flaps B.
When the car is ready for loading, the two bottom flaps B are connected to each other at their lower edges 6 by means of a Specification of Letters Patent.
Serial No. 4%,649.
locking device, such as hook b and pin 6 When the car is to be discharged, the loci mg device of the bottom flaps B is released, whereupon said flaps, by the weight of the load, begin to swing down about the axis oi? the bearings a and consequently open downwardly. The side walls 0, acting likewise under t re action oi? the weight of the load, follow the movement of the bottom flaps B and swing outwarc. in the direction indicated by the arrows 00 (F 1) until the have attained the position illustrated in F 2. Owing to this outward movement ot the side walls (I the space enclosed by them before the bottom flaps opened, increases so that even very bulky materials may be satistactoiily and automatically discharged.
The discharging having been effected, the movable parts of the car are returned into the position indicated in 1, whereupon the bottom flaps B are again connected to each other by means of the above-mentioned locking device.
I claim:
1. A self-discharging car having bottom flaps suspended on fixed parts of the car and movable side walls partaking of the discharging movement of said bottom flaps and suspended on fixed parts oi": car, the lower edges oi said s de walls resting upon the cor bonding bottom flap at points lying near to the middle plane of the car than the points at which the corresponding bottom flaps are suspended.
2. A self discharging car for material, dischargeable with di'lliculty comprising side members and a plurality ot bottom members openingdownwardly on the discharge of material from said car, said side members contacting with the contiguous-1y mounted bottom members said side members automatically opening outwardly by the action of the bottom members when taking up a discharging position.
The toregoing specification -signed at Essen, Germany, this 27th day of September, 1920.
