1'0 aZZ whom it may concern:

Be it knownthatLPnrnron H. KANE, a citizen of the United States, residing at Oil City, in the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in Car Loading and Unloading Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable oth-' ers skilled in the art to which it appertains to make and use the same.

The nature, scope, and purpose of this in vention willfully appear from the following description and claims.

The functions of the device are such that a railroad-car can be raised or lowervd, turned so as to face in any desired direction, tipped so that, if it is an open car, its contents will be dumped or spilled from the car, and, lastly, to weigh-the contents of the car.

The'objects or purposes of thus handling a car, are:

First. That the car may belowered so as to i receive massive pieces of freight without lifting the same up to the car. This use of the device will be specially desirable at points where cars or locomotives or large machinery of any kind are to be loaded. 1 Where this function alone is to be wanted, the device need not necessarily be provided with means for turning or tipping the car.

Second. That the car may be raised up and, if wanted, turned to face at an angle to the track, and tipped so as to dump its contents. This use of the device will generally be for unloading cars freighted with coal or iron ore,

and particularly where the contents are to be transferred directly into a ship. When thus employed the device will receive a loaded car from the main track in the same manner as a common turn-table. It will turn the car so as to face in the direction its contents are to be dumped. It will then raise the car, if necessary, to a proper height, and then tip the car so its contents will be dumped out. The device maybe made so as to tip the car, and, not-so as to turn it, or to turn and tip and not hoist it, orit may be made, as here shown, so as to perform all these functions. This will depend on the requirements, of course.

Third. That the weight of the contents of the car may be determined. a

The device is illustrated in theaccompany ing drawings, as follows:

Figure l is a side elevation. Fig. 2 is a like ing principal parts: A base, A, with a'central pivot, A, and a fixed concentrically-arranged gear, B, a superstructure which consists ofa platform, 0, mounted pivotally on the base A A, and an upright frame-work, 0 0 two lifting-jacks,.E E E E, and a car-receiving platform, D, mounted on trunnions D, which are journaled on the jack-pistons E E.

The operating mechanism consists of a steam-engine or other motor, H, mounted on the platform 0; a main shaft, G, operated by said engine; a pump, F, for operating the hy drostatic lifting-jacks, which is operated from said main shaft G; a pinion, B, mounted on the said platform 0 and gearing with the large concentricallyarranged gear B on the base, and operated from said main shaft G by the beveled gears B B, for the purpose of turning the superstructure pivotally on the base;- and, finally, segment-gears D D, connected with the car-platform D, and arranged concentrically with itstrunnions D and operated from worm-gears D which are operated from the main shaft, G by the intermediate gearings, I I I I 1 I I and D*, and the shafts I 1 which latter devices are employed for tipping the ca'r-platform soas to dump the con-' tents of the car.

The device for weighing the car and contents consists of an ordinary pressure-gage, K, connected with the chamber of one of the hydrostatic jacks by a pipe, k. By this device the weight of the whole mass sustained by the jacks can be noted both before andafter the car is loaded or unloaded, as the case 5 The device, as shown, consists of the followmay be, and the difference between the two I weights shown will be the weight of the contents of the car.

. above described. 4

The construction as shown in the drawings is as follows: The base A may be mounted-on.

masonry,or on a track which will be on a substantial foundation, For instance, if the device is used on a dock for loading coal, &c., ontoships' itmay be mounted on'a broad, firm track, so it can be moved from point to point along the dock, so as to be used at the termini of a 'series of tracks. The pivotblock A and the large gear 13 will be firmly secured to the base A Friction-rollers b are provided for supporting the outer edge of the platform 0. The frame-work C Chis firmly secured to the platform 0, and where desired it may be further sustained by guys 0 c c,

which connect with wheel, Gfl whieh ispivoted or'swiveled to the crown-block G of the frame. This swivel allows the frame to, re volve while the guys stand still. The uprights c of the frame serve as guides for the trunnion-boxes of the car-platform, which set on the pistons E E of the hydrostatic jacks E E, which are arranged within openings in the parts 0 of theframe-work. The hydrostatic jacks are both connectedwith the pump F by pipes ff, and thus both jacks are affected ex actly alike and simultaneously.

f 3 represents the supply-pipeleading to the pump, and f the waste-pipe, by opening .which the jacks are relieved of fluid and lowered. The pumpv E is operated by an eccentric, F, on the shaft G. The eccentrie F is provided with a clutch for throwing it into action. I have shown this as a ratchet-clutch, the shifting part of which is on the pinion B which is made to shift and be put in gear with either the eccentric F or the gear B, on the stem of the gear B, by which the superstructure is revolved. This double service of the part B is practical, because it will not be desirable to be working the .pump during the operation of turning the superstructure on its pivot.

'The mechanism for tipping the car consists of the segment gears D D which are arranged concentrically with the trunnions D D of the car-platform D and the worms D D and their operating-gears. The worms are mounted in brackets L on a frame, L, which is hung by straps L L, which pass up over the trunnion-boxes. The frame L is provided on each side with guide-heads Z, which embrace splines Z on the inside of the jack -barrels E. The frame L is thus supported in a horizontal position, and so that it moves up and down with the car-platform. On this frameis supported the following gearing for actuatingthe worms D D namely: the shafts I and I and the gears 1 1, 1 I and Di. The shaft 1* extends through a slot in the frame-piece O on the side toward the shaft G, and is journaledin an angle-bracket, i, which supports the sliding beveled pinion I on the upright shaft J, which is provided with a spline, j. The shaftJ is revplved from the main shaft G by the gears I I. When the car-platform is moved vertically,- the gear I is moved vertically along the shaft J by the bracket 2', and is thus always kept in gear with the pinion I on the shaft 1*. By this means the car-platform canbe tipped when at any elevation desired. The main shaft G passes the upright shaft J by a counter-"shaft,

G, and gears g g, as the construction is illustrated. The car is received on the tracks d on the platform D, and secured thereonin any manner desirable, (I show it. secured by chains,) so it will be held 011 theplatform as it tips.

The endboards of the car may be made re; h movable or be hinged, so as tolet down or swing up, or they may be fixed and immov: able, In the latter case of course all the, contents of the car willnot dump out, but a small part will be kept back by the end-board, and

will have to be shoy eled out. When the endboards are fixed, it will be well to provide a sheet-iron hood to go overthe end of the car and form a spout or covered chute.

c I do not intend to be limited to the use of hydrostatic jacks, for any of the well-known forms of jacks can be used in the connection hereshown by providing proper operating mechanism; but I consider the hydrostatic jack the bestfor the place.
