JOHN SCULLY, OF SOUTH AUBOY, NEV JERSEY.

MACHINE FOR UNLOADING CARS.

SPECIFICATION forming part of Letters Patent No. 394,727, dated December 18, 1888.

Application filed June 20, 1888. Serial No. 277,630. (No model.)

To all whom it may concern:

Be it known that I, JOHN SCULLY, of South Amboy, in the county of Middlesex and State of New Jersey, have invented a new and Improved Machine for Unloading Cars, of which the following is a full, clear, and exact description.

This invention relates to certain improvements in Letters Patent No. 366,033, which were granted to me July 5, 1887; and it consists, principally, in such construction of the machine that the shovels maybe shifted sidewis'e upon a stationary supporting-frame for carrying them to different positions in the car, and for carrying them from one track to another in case the machine is used on a double-track road.

The invention also consists of the construction, arrangement, and combination of the different parts of the machine, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is afront elevation of the machine. Fig. 2 is a plan view. Fig. 3 is a sectional elevation taken on the linew of Fig. 2, showing a car in position and the shovels partially lowered therein. Fig. 4 is an enlarged detailed front elevation showing the gearing for shifting the shovels laterally and showing the mechanism for raising and lowering and moving the shovels to and from each other. Fig. 5 is a transverse sectional elevation on the line y y of Fig. 4. Fig. 6 is an enlarged detailed and sectional view of one of the traveling frames or carriages and shovels, the section being taken on the lines of Fig. 7 and Fig. 7 is a sectional elevation taken on the line ,2" .2" of Fig. (3.

A A represent two elevated and parallel bars supported above and across the railway track or tracks B by the uprights or posts A A, so that said bars constitute an overhead track for the traveling frame 0 to move upon for shiftin the shovels D, held by said frame, to different lateral positions in the car B to be unloaded, and for shifting said shovels to either tracks. The said frame 0 is composed of the two parallel beams c c, mounted at their ends upon the trucks 0 c, and it is moved along the bars A A on said trucks by suitable mechanism under the control of the attendant, and hereinafter described, and the shovel-bars D, to which the shovels D are attached, are connected to the said traveling frame 0, and are adapted to be raised and lowered and moved to and from each other by suitable mechanism, also under the control of the attendant and also hereinafter fully de scribed.

About midway between and parallel with the bars A A are the central bars, A A supported by the standards or frame A A, one at each side of the railway-track. The bars A form a central support for the traveling frame 0, (on which it is supported by the trucks 0 0 and this frame also supports or incloses an endless chain, E, by which the frame 0 is shifted sidewise. (See Fig. 5.) The said chain E is attached to the frame 0 and passes over the pulley a at the support A and over the two pulleys b b at the other end, and around the drum C, which is revolved in either direction by the crank-shaft 0 through the medium of a train of gearing, C (Shown clearly in Fig. 4.)

The shovel-bars D are each held or rather sustained in vertical position by a carriage, F, placed upon and adapted to move or slide upon the traveling frame 0. The said shovelbars D are each supported upon and operated vertically by a rope, G, permanently secured at its outer end to a standard, g, and passed thence over the outer upper pulley, g, of the carriage F, thence down under a pulley, cl, at the side of the bar D, thence up over the opposite upper pulley, githence around the two pulleys m" on suitable standards, near the center of the carriage (1, down to the rope G. (See Fig. 4.) The two ropes G (one from each of the shovel-bars) are connected to the rope G, which passes from the point of connection down under the pulleys i at the base of the frame A, and thence up to the drum H, journaled in suitable bearing attached to the upright frame A, as shown clearly in the figures. In this manner only a single rope passes around the drum H, and by the revolution of this drum to wind up the rope the shovels and shovel-bars D D will be lifted vertically in the carriages F, and by reversing the drum to let out the ropes G G the said shovels and bars may be lowered into the car B to rest l upon the bottom thereof or upon any load or body of coal or other material contained therein.

The drum ll is revolved from the powershaft J, through the medium of the frictionwheel J, secured to the drum, and the smaller friction-wheel, J attached to the shaft J by a spline, so that the said wheel J is adapted to be moved upon the shaft. \Vhen the wheel J at its normal position upon the shaft J no motion will. be transmitted to the drum ll, but when the said wheel is moved to the right or left by the lever J the grooves of the wheel J will impinge upon the grooves ot the wheel J and cause the drum ll to revolve and cause the elevation of the shovels. 3y releasing thelever J the wheel J will alease the wheel J, and thus permit the shovels to drop of their own weight. The lateral movement ot. wheel J is but slight, covering only what slight space there may be between. the surfaces of the grooves when there is no pressure on the lever J.

The shovels I), besides having the vertical movement just described and the sidewise movement caused by the traveling of the frame 0 upon the cross bars or tracks A A, have also a l.)ack-and-torth movement to and from each other for sbiltingthe ltmdfrom the ends of the car to the diseharge-opening 13 (See Fig. 3.) This back-and-forth motion is produced by the shaft K, pinion 7c, secured thereto by a feather, k, and the two opposite rack-bars L L, secured to the carriages F F, as shown clearly in Fig. 3. The rack-bars L engage with opposite sides oi the pinion 7;, so that the revolution of said pinion imparts opposite motionto the said racks, causing them to move the carriages F and shovel-bars and shovels simultaneously to or from each other, according to the direction of revolution of the shat'tK. The said rack-bars .l) are held in tirm engagement with the pinion It by the rods 1 1, secured to the upper and lower edges of the plates 0 e and the flanged anti-:t'rietion rollers I" Z, secured upon said rods, as shown clearly in Figs. 33 and 5, and the shatftK isrevolvcd in this instance from the power-shaft J by the vert ical shat't K, beveled gear-wheels M m at the top, and the beveled gear M and reversing beveled gears m m at the lJOiLifOlll. The gears m m are arran ged on opposite sides of the gear-wheel M, and are connected to the power-shaft J by :t'eathers, an d are adapted to slide on said shali't, so that one or the other may engage the gearovheel M, according to the direction it maybe desired to move the shovels D. The gear-wheels m m are moved simultaneously by the hand-lever N and lever N, engagin the hubs of the said wheels and connected together by the rod N as shown in Fig. 4, so that the movement of the hand-lever in either direction will engage one ff being provided with wheels 7') at the top and p at the bottom, to run against the upper and. lower edges of the said plates c c, as shown clearly in Figs. ti and 7. The two blocks/"f" are united by the pairs of armsf f", reaching above and below the block f and the pairs of diagonal braces f f", and the block 1" is connected to the blocks ff by the side plates (1 q. (Shown in Figs. ti and 7.) The blocks f and ff are spaced from each other to form a channel to receive and hold the shovel-bars l), and yet permit them to have free vertical movement. At the top ot the block f are secured the two uprights [1, between which the pulley y or the rope Gis journaled.

At the lower ends of the arms f" is journaled the anti-Friction wheel .9, which braces and takes the strain of the Imekward thrust of the shovel-bar '1') when in operation, and the upper end of the shovel-baris held firmly between the pulleys g y so that the same is braced and heldv by the carriage both above and below the traveling frame (l. \Vhen the traveling frame (7 is moved sidewise by the endless chain E, the pinion 7.' slides upon the long shaft K and li'mtther 7.", so that there can be no disconnection of the mechanism which operates the shovels to and from each other. Upon each of the ropes (St is placed a weight, I, (shown in Fig. 'l,) to take up any slack in said ropes.

The shovels l) are each provided at their upper edge with a row of tines, d, to prevent. the shovels t'rom settling into the load too far.

l-Iaving thus fully described my invention, I claim as new and desire to secureby Letters Patent- 1. In a maehinet'or unloading cars, the travcling Frame (3 and the carriages i placed thereon and n-ovided with shovel-lmrs, in combination with the shaft K and connections with the carriages l and means, substantially as described, for shitting the travcling frame (1 upon its supports, as and for the purposes set forth.
