HOlSIINGAPPARATUS FOR LOCOMOTlVE AND PORTALE ENGINES.

SPECIFICATIQN forming part of Letters Patent No, 280,904, dated July -10, 1883. Application ined my 19,1353. (No model.)

citizen of the United States, and a resident of the borough of Columbia, county of Lancaster,

5 State of Pennsylvania, `have invented a new and useful Improvement in Hoisting Apparatus for Locomotive Iand Portable Engines, of which the following is a specification.

This improvement relates more particularly to locomotives employed in moving furnace# cinder from the furnace to the dump, but is applicable for various other purposes, and Willv be found of `great service on wrecking-trains or in connection therewith.

The object of the improvement yis to give to the operator in charge of the same the ability, through block and fall, a crane or 'derricln or by direct pull upon a rope or chain, vto hoist a- Weight limited onlybythe area of the cylinder and the pressure of the` steam. I attain this desirable result by the adoption of an openend cylinder conveniently placed, preferably 'as shown in the accompanying drawing, fornr ing a part of this specication, like letters designating .like parts throughout.

The figure represents inelevation the improvement adapted to dumping cinder-cars, in

which- A represents the front or smoke-box end of the locomotive; A, side frames; A2, bumpers oi same; B, an open-end cylinder; B', supplypipe leading from the front end of the cylinders up Within the cab of the locomotive, Where a three-Way cock is provided Within reach of the engineer, and through which the action of the hoisting apparatus is governed 5 B, exhaust-apertures in the shell of the cylinder; C, a piston of the usual construction; C, the piston-rod, provided at its outward end with a swivel or hoolrlcoupler; D, the derrickear; D', bumpers on saine; D2, floor of car; E, base-plate of derrick; F, stationary post secured to the plate E. It is turned upon its exterior. G, exterior movable postV or pipe, provided with a bearing-ange, G', at the base, and a boltingilange, L', at the top H, a collar in two parts, bolted by flanges at the base of the post1 and having ahub, I, for the reception ofthe jib. J is the jib, formed of a pipe 5o threaded at the ends, atthe lower end fitted in the boss or hub I, and at the top end inthe vthe ease.

\ bifurcated head-piece` K, provided with a sheave, M, and with pads K', for the tensionrods, and a sheave-pin, K2. The cap L has .standards L2, pin L3, and sheave M', with a hole central to the cap on plan, for the chain or Wire rope to pass through, also hubs LL for the tension-rods, and is bolted to the movable post G. The hoisting rope or chain is shown at N, and ring and slings at N N2. O represents lthe sides, and O the ends, of the einden-truck box; l), ears east upon the same; Q,-'trunnions for lifting by; R, center bottom 'plate;'R bumpers on same; S, outside bottom-platesgRZ, ears on all of the plates on their-lower faces, a fulcrum-pin, R3, passing through thesame and the sides of the truck; S', ears cast on the upper face of the bottom plates, and matching `with the earsr P oi' the box O O. A pintle, S2, common to all the ears, secures the box and floor together. 'I represents the cinder-truok sides; T the caps over the aXle-bearing boxes; T2, ends, and T3 center cross-bars. U represents a bar connecting the pedestals. V are tension-rods, and W temporary stays.

The construction and adaptation of my improvement is a simple matter, easily understood ,by an expert, the drawing fully explaining its use, which -Will be varied to suit the circumstances under which such usage is made. For many purposes-such as Wrecking, &c.- a short but powerful lift is desirable, and in this case the cylinder would be of large area and comparatively short stroke! In other cases a long stroke and moderate lift would better suitV To meet this, a cylinder of moderate size and stroke would have its lift increased in height, but reduced in effect, by a doubling up ofthe lifting-rope over blocks, similar to the Well-known hydraulic lifts.. Ihave shown the cylinder placed at the front of the locomotive and beneath the frame; but it may be plaeedwhere desired, as long as the liftingrope can be drawn without too many bends therein toward the cylinder, and it need not necessarily be placed in a horizontal position. The cylinder does not require a head at its rear The front `head is provi ded with the usual stuffingbox and gland, bored tol lit the piston-rod. The piston may be a plain plug with three or IOO more small grooves turned therein, the piston just moving freely in the bore of the cylinder, to save space in the front of the piston. I prefer to admit the steam directly through the front of the cylinder-head, to prevent the piston being carried out of the cylinder. I'have .f apertures made in the shell, which will exhaust or discharge the steam from the cylinder should the piston uncover the same, and 'its further movement would be stopped. The rod may be arranged in various ways at its loutboard end for connection with the hoistingrope. I give preference to a shackle, as shown.

The operation of the apparatus is as follows: The piston beingv at the forward end of the cylinder, and the rodprotruded to the extent of its stroke, -the hoisting-tackle is connected therewith, the engineer turns the three-way cock to pass the steam from the boiler to the hoistingcylinder, and the load is raised and held by the cock being partially thrott'led. When the load is blocked, the cock is turned to discharge the steam into the air. A'counter-balance will then retract the piston, or it will b e drawn back by hand, and the rod will again protrude,

, ready for a repetition of the lift.

ward the rear, the truncated box is raised, and by hinge-,connection with the floor raises that 35 also, and when the proper angle has been gained the cinder slips off. The4 cock is then turned to exhaust the cylinder, and the weight of box and floor brings the piston forward and seats the box upon the truck, ready for refllin g 4o and to repeat the operation.

Having shown the application and utility ofthe invention, I desire to secure by Letters Iatent the following claims thereon:

l. In combination with alocomotive or port- 45 able engine Vprovided with an independent hoistingcylinder, as described, a derrick and ear, whereby through arrangement thereof with block and fall the lift may be shortened and the lifting-power of the cylinder thereby 5o increased, and vice versa, substantially as and for the purpose set forth.

2.. In an independent hoisting-cylinder, as described, a series of apertures circumferentially placed at the limiting-point ofthe pis- 5 5 ton s movement, rearward from the front head, whereby the piston is held in abeyance without risk of further progression, the action of said cylinder-piston being controlled by the manipulation of a three-way cock, as and for 6o the purpose specified.
