" MACHINEFOR UN LOA`DING RAILROAD-CARS.
SPECIFICATION forming part of Letters Patent No. 279,868, dated .Time 19, 1883, Application filed April 27, 1883. (No model.)
To all whom 't may concern:
Be it known that I, ALMON HALL, a citizen of the United States, residing at Toledo, Lucas county, Ohio, have invented a new and useful Machine for Unloading Bailroad-Cars, of which the following is a specification.
My invention relates to a device for unloading ordinary railroad-cars by securing the car to be unloaded upon a platform or table dei signed to rise and fall, to rotate in a horizon= tal plane, and to tilt so as to dump the load froni the car.
In unloading coal and ore from railroad-cars into vessels and chutes the usual process of shoveling the load into tiltingvbuckets suspended from a swinging crane is found to be slow and expensive. Where dumping-cars of special Construction are employed their capacity is less than that of the ordinary flat car, and they can be used but for one class of freight. In unloading such vessels, elevated permanent ehutes are enployed, approached by inclined tracks of heavy grade. This plan is also objectionable on account of the great original cost of the elevated ways, chutes, and
cars, and from the fact that valuable docks and other spaces arranged on this plan are rendered practically useless for other purposes. i
The general object of my invention is to obviate the objections above mentioned, but more particularly, first, to provide a device for lifting a loaded car bodily to a height suitable for the operation hereinafter described, which device, when not in use, shall be below the track, out of the way of moving trains; second, to afford means of swinging the car completely around (as upon a turn-table) at any height to which it may be lifted; tlird, to provide mechanism by which the car may, at any point to which it is turned or lifted, be tilted to any desired angle, so that its load may slide or shoot from the car;` fourth, to arrange the engine which swings and tilts the car at or near the top of the lift cnnployed, so as to rise and fall and swing with the platform, dispensing with complicated gearing necessary were these Operations performed by a stationary engine; and, fifth, to combine with such device a pressuregage or scale for determining the weight of the load handled. I attain Similar letters refer to similar part-s through out the several views.
Table or platform A is of sufiicient length to receive a railroad-car. The beams are com-4 posed preferably of I-beams or channel-bars, suitably braced and tied, upon the tops of which are bolted track-rails a'. This table, when not in use, rests upon suitable supports, so that its rails a are on a level and in line with the rails of the track. Table A, at its center, is supported by and oscillates upon trunnions B. The car to be unloaded is secured to table A by chains or other suitable means.
C D is a hydraulic lift, cylinder C, closed at top, moving vertically within fixed cylinderl), which is closed at bottom. Cylinder C may also rotate upon its vertical axis. These cylinders are of sufficient diameter and weight to form an independent snpportingcolumn sufficient to withs'tandvertical and side straius and jars. The lift is supplied with water from aforce-pump through pipe u,
As it is impracticable with my device to provide the table A with the usual vertical guides, slides, and runway, which keepthe sliding cylinder vertical and in line with the fixed cylinder, the inner surface of cylinder D (or the outer surface of cylinder C, at its lower end) is supplied with projections (I, which touch the adjoining surface, leaving space for the free passage of water between the two cylinders. These points of contact, with but little friction, serve as guides for the inoving cylinder, and keep it steady and in vertical position.
C' is an open cylindcr provided at bottom with flange c', which is bolted to a eorresponding` fiange at the top of cylinder C. Piece C' has at top journals b b, forming bearings for IOO shaft and contains and supports' the 'mechanism by which table A is swung and tilted.
E E is a small double reversible engine,
which takes steam through a fleXiblehose, (not.
end pinion i, which, through an opening in.
C', engages horizontal (zog-wheel I. This cogwheel is fixed upon its shaft k, which extends downward through a stuffing-box in the head of eylinder C, terminating in cross-piece Z, (be low cylinder 0,) to which shaft k is also fixed.
On the inner surface of cylinder D are two pairs of vertical projecting ridges, m m. Single ridges projecting into a notch in the ends of piece Z would serve the same purpose. In the channels formed by ridges m m rest the ends of cross-piece l, which rises and falls with the moving column, but is prevented from rotating horizontally by said' ridges m m. The shaft k being fixed to. cross-piece Z and cogwheel I being fixed to shaft Ic, neither of these parts is permitted to revolve. XVhen pinion 'i is set in motion by means of its shaft and worm-gearing h g f, said pinion travels around the periphery of wheel I, (which stands fast,) carrying with it, in its circuit, column G C', to which pinion 'i is attached, together with all the load supported upon said column, the table A swinging upon its center, like a railroad turn-table, at any height to which it is lifted.
Cross-piece Z and ridges m may be dispensed with by allowing shaft k to extend through the bottom of cylinder D, said shaft being provided with a fast feathcr to prevent its revolving. Shaft k may also be dispensed with by attaching wheel I to top of cylinder C, and constructing the connecting-fianges of C and C' so that one flange may overlap and partly embrace the other, thus forming a joint which will permit C' to rotate horizontally upon cylinder C, as shown in section in Fig. 5.
Table A is provided at either side with seg- 'mental toothed racks F F, having for their center trunnion B, and which -racks, in addition to their function of communicating 1110- tion to table A, serve as braces or trusses for table A. Racks F F are engagedby pinions n upon the ends of shaft o, which passes through cylinder OC Fixed to shaft 0 is worm-wheel 1), which is engaged by screw q upon vertical shaft a', which is provided at top with beveled pinion s, to which motion is imparted by beveled gear wheel t upon shaft e of the engine. I
Upon motion being communicated to shaft 0 through 19, q, r, s, and t, pinions n n revolve', causing segmental racks to travel, carrying with' them their attached table A, which tilts upon trnnnion B to a sufficient 'inclination to permit the load contained in the car to. slide out. i
lt will be observed that worm-gearing 1) q serves as a constant safety-lock, preventing motion of table A upon its trunnions unless said worm-gearing is actu'ated by the engine.
Shafts h and r are provided with clutches h' and r', by means of which either the swinging or tilting machinery may at will be thrown in or out of gear.
Other arrangements of engine and gearing' will readily suggest themselves for swinging and tilting table A, and I therefore do not confine my invention to the particular arrange= ment of engine and gearing here described; nor do I limit my devce to a steam-engine, as obviously the pump employed for Operating' the lift could also be utilized for actuating hydraulic pistons or jacks, which would accom= plish the same results. Neither do I limit my invention to a hydraulic lift, as piece C' or its equivalent might, with all its attachments, be hoisted by' screws or racks and pinions. The arrangement here shown is more particularly designed for use on low docks, subject to high waters, in loading large ves .sels, which, when light, set many feet above the (lock, but which, when loaded, may sink so that the deck may be below the level of the dock or pier.
G is a pressnre-gage or scale attached to or connectedwith hydraulic lift C D, and serves to indicate the pressure of the fluid within cylinders C D and the resistance and weight of the superimposed load.
I am aware that a turn-table operated by hand, supported upon revolving vertical screws, has been employed for the purpose oi' lowering and raising small cars and wa'gons into and out of the holds ofvessels, and I do not claim a horizontally-rotating table combined with a lift; but V hat I do claim as my invention, and desire to secure by Letters Patent, is
