CARL F. ASTROM, OF ORANGE, NEW JERSEY, ASSIGNOR TO M. H. TREADWELL rb CO., A COR- PORATION OF NEW YORK.

Moron-OPERATED DUMPING-CAR.

Be it knownthat I, CARL P. As'rRoM, a subject oi the King oi Sweden, and a resident of Orange, in the county o1 Essex and State of New Jersey, have invented a new and Improved Motor-0perated Dumping-Car, oi which the following is a full, clear, and exact description.

My 'invention relates to improvements in motoroperated dumping-carswethat is, to, improvements in cars which are dumped by means oi a steam'cylinder or compressed air, dmc.

The general description of car to which my yimprovementsare shown in the drawings 'as being applied is that described in my United States Letters Patent No. 755,207. This car is a cylinder-operated cinder-car, the cylinder reciprocating 4on a `fixed piston and piston. rod and under the iniuence o the motive iiuid being adapted, through connectionsAbetween the cylinder and one of the trunnions 'oi the car body, to travel from one side of the car to the other, causing at the same time the car body to, itself. tilt and travel correspondingly, the car body being provided with two oi said trunnions,w ith a -gear wheel on each trunnion meshing with stationary racks upon which the said gear wheels travel.

The objects ol' my present improvements are to provide improved means for locking the reciprocating cylinder, and consequently the car body, in fixed position, also means for cushioning the moving parts, so as to take up the shock oi impact as said moving parts travel from one extreme position to the other in dumping and righting the car body.

In the accompanying drawings, Figure 1 is an end elevation of a dumping car suitable for conveying cinder and embodying my improvements. Fig. 2 is a side elevation oi one end of said car-to wit, the end shown in Fig. l.. Figs. 3, 4 and 5 are detail views, Fig. 3 being a side elevation, partly in section, of the motor cylinder, the cushion cylinder, and their related parts. Fig. 4 is a transverse section ol Fig. 3 along the line 4 4 looking in the direction oi the arrows. Fig. 5 is a detail oi the locking pin in locking position. Fig. 6 is a view of the member L and oi the pin I viewed from the right-hand side of Fig. 5.

l is thecar body mounted in a yoke 2 having at each end trunnions 3 and gears 4 rolling respectively on tracks carried by the pedestals of the car frame and racks 8.

B is a movable operating cylinder mounted to reciprocate on a fixed rod A between the sides oi the frame and carrying a hollow casing 5 on its rear side. The hollow casing 5 receives the end oi the trunnion 3 anda suitable lbearing box,not shown The hollow Specification of Reissued Letters Patent.

casing 5 also carries a detachable pin or key 6 which is adapted to iasten the trnnnion at one or the other end of the hollow casing, and consequently permit the car body to be dumped on either side, as is fully explained in my Patent No. 755,207, above mentioned.

In operation, the pressurey is admittedon one or the othervside of the fixed piston Y through the passages T in the hollow rod A by a suitable controlling valve, to move the car body in one or the other direction, as will be understood. i Describing now my improved locking device I may state at the outset that its purpose is to lock and hold in stationary position the moving part oi the motorto wit, the cylinder-and consequently since the cylinder is connected to the car body to lock the latter likewise in stationary position.

The locking-device shown in the drawingsl illustrates one form which my improvement may take. Thisdevice is shown in duplicate on each side of the car, that on the r-ight side of Fig. l comprising the pinv .1, the notched extension G, rigidly connected to the motor cylinder, and the openings H and H (see Figs. 2 and 5) formed in the upwardly extending webs K and L of the stationary base plate O. These openings H and H/ are adapted to register with the opening in the member G when the cylinder is reciprocated, so that it occupies its extreme righthand position, (see Fig. l) the pin I being then adapted to be inserted through said openings and to be retninedin that'post tion, whereby the cylinder is immovably locked to the base plate O.

For the purpose of locking the-cylinder` in its eirtreme leithand position, the locking'derice is duplicated on the left-hand side of the car, tho same oomprising the pin t, the notched member g. and the openings h and h (hf not being shown) in thc 'vertically extending Webs of the base plate, these beingin all respects similar to the looking means on the righthand side of the car, previously described.

Desbribing next themeans for retaining the pins l and'i in locking position, it will bc noted that each of said pins is provided with a spline or lug J, (see Fig. 5) also with a handle, the said spline and handle projectlt will be noted that the aforesaid openings (see l1., Fig. l) in the webbed portions of the base plate are keyhole-shaped to lit and receive the spline portions of the pins. lt is apparent that to insert the pins the spline portion must be down, and, further, that after said pins are inserted through the openings and the handles turned vertically downward, which is the position they will naturally seek and retain, dueto the weight of the handles, that said splines will then engage the sideso the rear opon- The pins are preferably attached to the'car by chains, as shown, to prevent their being lost.

Describing now the means for cushioning the cylinder and relieving it and the connected parts from shock when it reaches its extreme limit of motion, one of the orms which my invention may take in this respect is shown in the drawings and may be described as follows: The cylinder D, hereinafter called the cushion cylinder, is rigidly secured to the motor cylinder B and reciprocates therewith, the same reciprocating, like the motor cylinder, upon a fixed pistn Z and piston rod C. The valves F and f .at the ends o the cushion cylinder are 4adapted to allow outside air to be sucked through them into/the cylinder, but to resist the-passage 'of cylinder air out ofthe cylinder. Thel opening E is an opening made through Ythe walls ot the cushion cylinder at its middle portion. l The operation of the cushion cylinder is as follows: When steam or compressed air, &c., is applied to the motor cylinder and it is driven from one side oi the car to the other, the cushion cylinder travels with it, and as soon as the central opening E in the cushion cylinder passes the piston Z the air entrappedbetween said piston and the walls o the cushion cylinder is compressed i'or the rea-son that the valves F or f (as the case may be) at the end of the cylinder resists the escape ,of air out of vthe cylinder, andthe piston Z of course fits'steam-tight within its cylinder. This compression of air gradually' increases to the end of the stroke, and the moving parts are thereby'gradually brought to a standstill, thus relieving the various parts of the car from shock and excessive strain.'

The spiral springs R and S (shown in Fig. l as surrounding. the ends oi the piston rod C) are held in fixed position at the sides oi the car and so placed that the cylinder somewhat prior to reaching'its extreme limits of travel Vstrikes against one of said springs, with the result that the workvoi compressingudone'upon said spring brings the moving parts gradually to a stop.

Obviously some features of this invention may be used without'others, and the invention may be ernbodi'ed in widely varying forms.

Therefore, without limiting the invention to the construction shown and described, nor enumerating .equivalents, I claim, and desire to obtain by Letters Patent, the following:
