DUMPiNG-CAR.

SPECIFICATION forming part of Letters Patent No. 676,104, dated June 11 1901.

Application led October 1'7, 1900. Serial No. 33,371 (1I o model.)

To ally/71,0111, it maycmwewe:

Be it known that I, JACOB J. SOUDER, a citizen of the United States, residing at Washington, in the District of Oolu mbia, have invented certain new and useful Improvements in Dumping-Cars; and I do herebyT declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in railway dumping-cars, and is more particularly designed as an improvement in that form of car shown and described in my pending application, filed August 2t, 1900, Serial No. 27,9i8.

The dumping -railway car which consti` tutes the subject of the application above referred to operates with entire satisfaction when the car has been supplied with the smaller grades of coal or of coke; but in some instances it has been found that when very coarse grades of these fuels have been supplied to the car the weight and the friction of these rough surfaced materials as they 4have rested in directcontact with the winding-shafts of the car have somewhat restricted and diminished the facility of their operation; and a leading object of this invention is to provide means for avoiding the delay and annoyance which have resulted from the direct-contact of a portion of the contents of the car with the winding-shafts which operate the hopper-doors of the car, while another object is the provision of ameans for retaining the hopper-doors in position when they have been closed.

With these objects in View the invention consists in various novel parts or combinations of parts in a railway dumping-car, as will appear from the following description thereof and from the speciiic and distinct claims of novelty which succeed such detailed description.

In the accompanying drawings, which constitute a part of this specific description, Figure'l represents a perspective plan view,partly in transverse vertical section, of a dumping railway-car which is provided with my improved shielding and guiding appliances and with my improved retaining mechanism for preventing inadvertent or premature discharge of the contents of the car. Fig. 2 is a longitudinal central vertical section of the car represented in Fig. l, and Fig. 3 is a perspective view showing details of the hopperretaining mechanism.

Referring to the drawings, the numeral 1 designates the longitudinal central sill, and 2 the longitudinal side sills, of the car-body, surmounting which side sills are the sides 3, while extending from endto end of the bed-y frame of the car and arranged at regular in tervals is a series of transverse sills (not shown) for bracing the side sills 2 2 against the center sill 1. This construction, however, is thesame as in the pending application hereinbefore referred to, and further description is therefore unnecessary. i i

By meansof the longitudinal sill land the transverse sills the entire body of the car is divided into a series of dumping-spaces, and hingedly connected to the longitudinal sill l, at each side thereof, is aseries of downwardlyopening inner doors 4, which coperate with a series of downwardly-opening outer doors 5, hingedly connected to the inner sides of the side' sills 2. The doors 4 and 5 when closed form `longitudinal hoppers at the sides of the longitudinal sill 1, and extending throughout the length of the car in vertical alinement with the center of each of said hoppers is a longitudinal winding-shaft 6. At suitable intervals throughout the length of the shafts G the same are each provided with lifting-chains 7, the latter being suitably connected at their lower ends to the doors lland 5, and it is therefore obvious that when the shafts 6 are rotated in one direction the chains 7 will be wound thereon and the doors thereby closed, while with a reverse rotation of said shafts the chains 7 will become unwound and the doors et and 5 thereby permitted to gravitate in order to be opened. For effecting the rotation of the'shafts 6 a transversely-extending counter-shaft 8 is employed, which shaft operates the shafts 6 through suitable bevelgearing, (not shown,) and the operation of the shafts A6 for opening and closing of the doors 4t and 5 simultaneously is thereby effected. The construction of the doors 4 and 5, the shaft 6, the chains 7, the counter-shaft 8, and its gearing with the shaft 6 is the same as shown in the pending application referred to; but in the operation 0f the car covered by this pending application it has been found, as already stated, that the contents of the body when it is desired to dump IOO face ofL such sill.

the same sometimes interfere with the working of the shafts 6 and 8. Tov overcome this objection, the shafts 6 and S and the longitudinal and transverse sills are each provided with an inverted-V-shaped protector 9, and by reason of the provision of said protectors it is obvious that the shafts 6 and 8 and the longitudinal and transverse sills are protected kagainst contact of the contents of the car, which will. be directed to the right and to the left away from the winding-shafts.

To lock the doors 4 and 5 against possible opening, a series of locking-,bars 10 is arranged beneath the body of the car at spaced intervals and each pivotally connected to the longitudinal sill 1 through the medium of a perpendicularly-arranged boltI 1l, which Vby its upper extremity is secured to the bottom rPhe ends of the bars 10 when transversely arranged, asin Fig. 1, project beyond the meeting edges of the doors 4 and 5', and thereby underlie the same, and when in this position each of the bars is adapted to engage a pair of transverselyalined reversely-arranged hangers l2, which depend from the winding-shafts 6 and which are received in coincident notches 13, which are formed in the meeting edges of the doors 4 and 5. For edecting uniform and simultaneous movement of the locking-bars 10 a longitudinally-extending link 14 is connected to said bars throughout the length of the car, so that all of said bars move at once, and in order that said link 14 may be properly moved for shifting the locking-bars into and out of 45 lated by the operator. fsw/The operation of the herein-described mechanism is as follows: When the body of the car is filled, it is obvious that the contents are prevented resting directly upon the shafts 6 and 8 by means of the protectors 9, and said shafts are thus capable of free operation without interference by the contents of the body. Should it be desired to dump the contents, it is simply necessary to operate the lever 15 in such manner that the same disengages the locking bar A10, to which it is connected through the medium of the link 16, from the hangers 12, and said locking-bar being counected with the other locking-bars throughout the length of the car transmits the motion of the shaft 15 to said bars, with a resultant disengagement of the entire series of bars 10 Jfrom their respective hangers. The shafts 6 are thus permitted to rotate in such manner that the chains 7 are unwound and the doors 4 and 5 are permitted to fall to their discharging position. The contents of the body will operating-lever 15, when the now descend and will be evenly distributed throughout the area covered by the car. After the discharge of the contents the doors 4 and 5v may be closed by simply rotating the shafts 6, whereupon the chains 7 Wind thereon andthe doors 4 and 5' are elevated so that their angular edges meet. After the doors 4 and 5 have been closed the locking-bars 10 are swunginto engagement with the hangers 12 through the proper manipulation of the be again loaded.

The invention having been thus described, what is claimed is--e- 1. In a railway dumping-car, the combination with the bed-frame thereof, of a series of oppositely-placed. discharging-doorsy which are hinged to such bed-frame, which extend from end to end of the bed-frame, and which in closing unite by their free extremities to constitutea hopper-shaped bottom; a winding-shaft which is mounted upon such bedframe, which extends, in ahorizontal plane,

, from end to end of the bed-frame, and which isoperated byinterconnecting chains, to close or to release the oppositely-placed meetingr doors; and the described A-shaped protector or guard, mounted above the winding-shaft, at a short distance therefrom, and extending from end to end of the winding-shaft, and of the car; as and for the purposes set forth.

2. In a dumping-car, the combination of winding-shafts, mounted upon the bed-frame of the car, and extending from end to end of the same; two series of oppositely-placed discharging-doors which are hinged to the longitudinal sills of the car, and which when closed unite to constitute a hopper-like bottom; chains which are connected to the winding-shafts, and to the free extremities of the oppositely* placed discharging doors; supporting-bolts which are secured in the body of the central longitudinal sill of the car, and which extend perpendicularly downward therefrom; horizontally-arranged supporting-arms or locking-bars, one of which is centrally pivoted at the head of each of the supporting bolts; reversely arranged hangers which are mounted upon and extend downwardly from the Winding-shafts; a horizontally-arranged transversely-extending lever which is mounted in the bed-frame of the car; and a link which is connected to the horizontally-arranged lever, and to the pivoted supporting-arm or locking-bar, the several supporting-arms or locking-bars being united l for action, by intermediate connections, as specified, whereby the entire series of supporting-arms or locking-bars are simultaneously moved either into or out of their securing position.

In testimony whereof I aiiix my signature in presence of two witnesses.
