To all whom it ma concern: y

Beit known t at ll, WILLIAM D. SKI-D- Monr., a citizen of the United States, and a resident of Pelham, Westchester' county,

State of New York, have invented certain new and useful Improvements in Dumping- Cars, of which the following is a specification.

My invention.. relates to railroad cars, more particularly` to that class of cars known as 'dum in cars such as are used for instance, in railroad construction, for conveying ballast, filling material and the like to such places as' the same may be needed, and dumping the same upon or at the side of the right of way; but it will be readily understood that cars constructed yaccording to my invention may be used for other purposes as well as'those above specilied.

. The object of my invention is to provide a ca r which shall be sim le in construction -andat the sametimev e cient and easyof operation, and which shall be adapted to dump its load either quickly and all at one time, or slowly vand at a predetermined rate of discharge, and in which the adjustment of the mechanism so as to regulate lin the accompanying drawings, Figure 1 is a side elevation of the end portion of4 a car constructed accordingV to my invention. Fig.. 2 is an end elevation of a` car constructed according to my invention, 'showing the lsame loaded and in its normal erect or carrying position. Fig. 3 is a transverse vertical. section through a portion of the car, in its normal position. Fig. 4 is a similar view, certain portions being broken away, showingthe car in its wide open position for dumping at the side of the track. Fig. 5 is a transverse vertical section of one side of the car, showing the same arranged for 'dumping on the track between the wheelsof the car. Figs. 6 and (a are detail views hereafter .further described. Fig. 7 is a detail elevation of the drums upon which the controlling chains are wound. F ig. 8 is a detail viewof the. controlling mechanism. Figs. 9 and l0 are respec-,tively front andv side views of the air cylinder. Fig. 1l is a .cross-sectional View through the cylinder. Fig.` 12 is a'detail view of a channel-iron more specifically referred to in the specification.

v In carrying my invention into effect, ll provide .for the lower part of the car a .running gear of the common or any suitable form of construction, comprising the necessary sills, holsters or analogous members,

mounted upon bogie trucks provided with journal-boxes forming the bearings for the ends of the axles, and supported by and secured to the running gear in any suitable manner are end members 12 and a bottom frame 14.

Referring particularly now to Figs. 3, 4 and 5, it will be seen that securely attached to the end frame members 12 and extending longitudinally of the car body oneach side of the car, are ehannel-irons 16, to which are secured -members 17, extendin slanting direction downward and inward. These members 17 are rigidly secured, and

, do'not change their position, but they bear swinging members .19 pivotally secured thereto by hinges 18. Extending upward from the bottom frame 14 is a bracket 22, and pivotally attached at 21 to this bracket are swinging members 20.

The parts above described form the carrying bodyT ofthe car, and they are shown in Fig. 3 in a closed or carrying position, in Fig. 4 in a wide open position adapted to deliver the load at the side of the track, and in Fig. 5 in position to deliver the load on the track vbetween the wheels.

When the car body is in the closed or carrying position shown in Fig. 3, the outer edges of the members 20 are supported by legs 28, (diagrammaticallv shown in Figs. fi and 5) pivotally secured thereto by their upper ends. rllhe lower ends of the legs 23 bear normally upon rollers 24: journaled in brackets upon a cl1annel-iron 25. This construction is shown in detail on an enlarged scale in Figs. 6 and 6 3.

ina-

rll`he channel-iron 25 is supported/on wheels 258 which run upon a traclrway 25". 'llhe channel-iron 25 and the track-way 25 are provided with openings 25 (see Fig. 12) through which the leg 23 may drop down when the channel-iron 25 is drawn toward the right of Fig. 6, thus allowing the parts to fall into the position shown in the dotted lines in Fig. 6. Levers 65 areprovided for operating the' channel-irons, shown in Fig..1,. and on an enlarged scale in Figs. 9 and 10. .The member 20 is also `supported by the link 2.9,.the lower end of which is pivotally secured at 28 to the said member nearits outer edge, and the upper end of which. is securedl to the chain 31 which passes over pulleys '35 and Varound drums 37 on the shaft 36..

vThe lower edge of the swinging member y19, when in the closed p osition shown in Fig. 3, is supported upon the'upper or outer edge of the member 20. It is also supported by the link 27, the lower end of `which is pivotally'secured at 2G to th hhhr lhhd thupphhd il i l0 lli@ 'h' ll l l wir@ is pivoh y rauh, il upper endof the member 29 and to the chain 31. It is obvious that the shaft Y36 is rotated so as to wind the chain 31 thereonl the links 27 and 29 are drawn up and with them the upper and lower edges respectively' otl the members 20 and 19, as shown in Fig. 3. but when the chain is partially or completely unwound the parts assume the position of Fig. 5 or 4 as the case may be. v

Pivotally secured' to the frame at 34 is a member 33. When the car is in a position for-dumping at the side of the track the member 33 is placed in the position shown in Fig. 4, but when it is desired to dump on the track between the rails the member 33 is placed in the position shown in Fig. 5. When the car is in the closed or carrying position the member 33 may lie either way. This member 33 is manipulated by hand or in any suitable manner. 1t will of cour'se be understood that these various parts above described are duplicated on the two sides of position (as shown in Fig. 4) when the dumping is at theside of the track. These results are obtained bv means of the mechanism now to be described.

Pivotal'lyv attached to the frame of the car,'one on each side, are levers 70, (see Figs. 2-5) which normally tend to swing down by their own weight, but which may be secured in theelevated position by catches 71 (see Fig. 2). Rigidly secured to these levers, at their inner or pivoted ends, are cross-bars 72, to the ends of which are secured links 73 and 74 respectively. The lower one of these links, designated 74, has its lowerend pivotally secured to an arm or block-176pivotally secured to the ...shortlink 79 which is pivotally secured to a swinging block or stop 80, near one end thereof, the other end of said block 80 being pivotally secured -at 81 to Vthe frame. It,

will be obvious from anpinspection of Figs. 2, 3, 4 and 5, that when the lever 70 is lowered and the parts are in position shown in Fig. 4, the arm or block 76 bears against the links 27 and 29 and prevents them from buckling and thereby upholds the swinging 'member 19, but `that whenthe lever 70 is' raised and the parts are in the position shown in Fig. 5, the block 80 bears against the joint of the links 27 and 29 and holds them in the position shown in' said Fig. 5

hlhihihiphhnhlhhihghghihihi l l ll (l lllhminhmg hlhionhih'. N

The operations of opening the sides of a car constructed according to my invention,

so as to discharge the load, and of closing 'thereby wound up and the links 27 and 29 raised. During this operation the shaft is held against backward rotation by a pawl 39 (see Fig. 8) which engages with a ratchet 120 which is fast on the shaft 36. This A pawl forms part of a lever 41. pivotally se cured to the frame at 101.

The construction of this pawl and the devices immediately related thereto is shown in detail in Fig. 8. The lerer 41 is pivoted to the end of the car body at 101, and may be locked in the position shown in the drawing by means of the pin 130, which passes through a perforation in the saidlever 41 and a corresponding perforation in the member 132.

41 by means of a sleeve 109, rigidly mounted T on the said rod .41. `Also pivoted at 101 is an L-shaped lever 110, having its movement limited by the guide 111, and provided at one end with a notch adapted to be engaged by the ltooth 135. To the other end of this lever 110 is pivoted the pawl 39, as shown at 112. a portionof said pawl near the outer maan ai until it strikes against the stop 133. The lever` 102 is then moved against the pressure of the spring 103, thus disengaging the tooth 135 from the recess in the lever 110. AThe pressure of the ratchet wheel against the toe of the pawl 39 forces the same upward, the lower end of the lever 110 moving to its extreme left hand position, thus allowing the free rotation of the ratchet 120.

When air is used for operating the mechanism, it is applied by means of the devices' is intended to operate a pinion 47 being guided or steadied by the roller.90 (best shown in Fig. 7, which is a side elevation, lookingI from the left, of the portion of Fig. 2 just above the cylinder 49) the said pinion 47 being fast on a windlas's-shaft 91 which also bears winding drums 92. Attached to these drums and adapted to be wound up thereon are chains 93 (see Fig. 2) the other ends of which are secured to the winding drums 94 on the shaft 36. (See Figs. l and 7.) Since this same shaft 36 also bears the winding 'drums 37 and upon which are wound the chains 31', unwinding the chains 31 on the drums 37 winds up the chains 93 on the drums 94 and vice-versa. A' guide roller 54 (see Figs. 9 and 10) is provided for directing and steadying the movement of the piston.48. On the piston rod 48, just below the guide roller 54 but on the forward side of the pistonrod, is a lug `or toe 50, which operates the bar 51 when the piston is raised. Connected to the ends of `this bar 5l are links 57 (see Figs. 9 and l0) which are connected to the forward ends of bell-crank levers 59, the other ends of which are operatively connected to the channel-irons 25`heretofore described.

The operation of my invention is as follows: Suppose that it is desired to dump by hand, and' in the middle of the track, between the rails; the members 3 3 are swung into the positions shown in Fig. 5, and the levers (which normally when the car is closed lie in the position' shown in Fig. 3) are swung upward'. The levers' 65 are then operated, which draws the channel-irons 25 out and permits the swinging side members 19 and 20 to drop into the position shown in Figi 5 and thus-permit the load to discharge. After the car has been emptied of its contents. cranks are applied to thesquare ends of the shaft 36 and mi by rotating the' 'saam the chains l31 are wound up and the swinging members are replaced into the position shown in Figs. 2 and 3, whereupon the levers 7 0 are elevated and secured by the catches 71.

Suppose it is desired to dump outside of the track, on both sides. ln that case the swingingmembers 33 are placed in position shown in Figs. 3 and 4, and the channelirons 25 withdrawn as before, whereupon the members 19 and 20 swing outward to the full extent, as shown in Fig. 4, and are held there by the operation of the block against the links 27 and 29. After the discharge the swinging members 19 are replaced as before described, the levers 70 being first elevated so as to withdraw the blocks 75 and permit the links 27 and 29 to be moved, and the channel-irons 25 are pushed back into their supporting position.

If it be desired to dump on one side of -the track only, the operation is the same,

eXcept that the parts on the corresponding side of the car only are operated. i

When the dumping is to be done by power, the opening and closing of the sides are performed by admitting air to the cylinder 49. If air is admitted below the piston, the rod 48 is moved upward, and by -means of its rack operates the pinion 47 which unwinds the chains 93 from the drums 92, and allows the same to be wound up upon the drums 94, thus allowing the chains 31 to unwind from the drums 37. The levers 70 must of course first be released. To elevate the sides, air is admitted above the piston, moving the rod and rack downward, and operating the parts in the contrary manner to that just described. The determination of the load to the middle or one or both sides of the' track as the case may beis accomplished in substantially the same way as is done when the load is dumped by hand, as has been already de:4

scribed. i i
