GUSTAV IIILGENSTOOK, OF DAHLHAUSEN-ON-THE-RUHR, GERMANY, AS-

SIGNOR TO THE UNITED OOKE AND PENNSYLVANIA.

GAS COMPANY, OF PHILADELPHIA,

SPECIFICATION forming part of Letters Patent No. 649,451, dated May 15, 1900.

Application filed March '7, 1898. Serial No. 679,982. (No model.)

To all whom, t may concern:

Be it known that I, GUSTA'V HILGENSTOCK, a subject of the King or Prussia, German Emperor, residing at Dahlhausen-ontheRuhr, in the Kingdom of Prussia, German Empire,have invented a new and useful Device for Drawing Up the Doors of Coke-O vens, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form apart thereof.

My invention relates to coke-ovens arranged in series side by side and having their doors lying in or substantially in the same plane, as is usual in such constructions.

The object of my invention is to provide a simple and convenient mechanism whereby the doors of the coke-ovens can be drawn up at will and by the action of a single fixed motor. Vith this object in view I provide a track running along and above the top edge or edges of the bank or group of ovens and place thereon a truck carrying a windlass. In practice the truck is moved to a position over the door to be lifted and is then anchored in position by any convenient means. A hoisting chain or rope is secured to the Windlass-drum, and said drum is `also provided with means for actuating it, adapted to be connected and disconnected at will with a series of drum-actuating devices, which in accordance with my invention I arrange at convenient intervals along the top of the bank of ovens and all of which I connect with a motor, by means of which each or all of said drum-actuating devices can be operated. Preferably my drum-actuating device consists simply of a series of rings connected to a chain running parallel to the track and longitudinally reciprocated by means of a motor, said rings being connected to actuate the drum by means of a chain wound on the drum and having a hook bywhich'it can be attached to any of the rings at will.

My invention can be appliedin a great number of modiiied forms without departure from its fundamental features; but its general nature will be clearly understood, as described in connection with the drawings, in which I have illustrated my invention in what I believe to be at once the simplest and best forni,

and in Whichl Figure 1 is a front elevation of a bank oi coke-ovens equipped with my improved doorlifting device. Fig. 2 is a plan view of the door -lifting mechanism. Fig. 3 is an enlarged elevation showing some of the ovens, the Windlass, and its immediate connections, Fig. 4 is a side elevation of the parts shown in Fig. 3; and Fig. 5 isaplan view, on an cnlarged scale, of the hoisting-windlass.

d indicates the bank of coke-ovens, and 7L 71 itc. the vertically-movable doors, having perforated ears, as indicated, at their tops.

c c, dto., indicate a structure for supporting the track. It is made, as shown, with cross-bars c' at top, upon'which the rails b l) are supported and which also support a series of supporting-rolls, (indicated at e c, dac.)

B is the platform, conveniently extending out from the end of the row of cokeovens and level with the top of the ovens.

a is a wheeled truck moving out on the tracks b b and' supporting a bipartite drum, (indicated at d a2.) c

M indicates the motor, which may be con'- veniently constructed, as shown, of a long cylinder, (indicated at m2,) in which Works a piston, (indicated at m', Fig. 1,) m indicating the piston-rod. i

m3 indicates the conduit for steam or other iiuid leading to the cylinder m2, and n indicates the valve for regulating the admission and exhaust ot' the motive iiuid from the cylinder.

n indicates a lever valve n.

o o' 02 indicate a lever-actuating connection which by means of bellcrank levers (indicated at o3) can be moved by depending handle-rods o4 04, arranged at convenient intervals along the front of the bank of coke-ovens.

The position of the motor is of course a mate ter of minor importance, and I have shown in dotted lines at M, Fig. 1, that the motor can be placed in a vertical instead of a horizontal position if it is found more convenient to do so.

f indicates a chain connectedwith the piston-rod m and extending, as shown, between for actuating the the rails of the track along the top of the structure c, the chain being supported on the rolls e e, &c., and passing atA the end ot the bank of coke-ovens over a roller or pulley e2, a weight Zbeing attached to its end, so as to keep it tant. Preferably I connect a second chain f with the other end of the piston-rod m and carry it over a pulley e3, attaching a weight l to its end, the weights Z and Z balancing each other and leaving on the motor only the duty of actuating the chain and the connections made to it in practice. At convenient intervals, preferably the distance apart of the doors 7L 7L, I secure to the chain f a series of rings g g;

c' is a chain Wound on the drum a and conneetible at its end to the lugs at the top of the door-h. y 7c is a chain Wound on the drum portion co2 and-con-nectible at its free end with any of the rings g.

v Preferably I make the chains t' and 7c separate, connecting each with the drum independently at a2 k2,- but obviously the chains may be connected and continuous and sim ply passed over the drum.

In practice the windlass-trnck is moved to a position immediately above the door to be raised, anchored in said position, and then the chain 7o connected with the convenientlysituated ring g. The motor M is then set in operation, connecting the chain j' and the rings attached to it and drawing up the door h connected with the chain t'. A reverse movement of the motor-piston permits the door to again fall to a closed position, and the windlass-truck is then moved to another position, connected as described, and the same operation performed.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In combination with a series of cokeovens arranged side by side in a group, a movable hoisting drum adjustable along and above the ovens, a hoisting-chain secured to the drum and adapted to engage the doors of the ovens, a series of drum-actuating devices, as eyes g, arranged at intervals along the top of the ovens, a motor arranged to actuate said devices, and a chain wound on the drum and connectible at will with the individual members of the series of drum-actuating devices.

2. In combination with a series of cokeovens arranged side by side in a group, a movable hoisting drum adjustablev along and above the ovens, a hoisting-chain secured to the drum and adapted to engage the doors of the ovens, a longitudinally-movable device, as chain f, running parallel to the line in which the drum is adjusted, means for moving said device and a chain for actuating the drum sccured thereto and attachable also to the longitudinally-movable device aforesaid.

3. In combination with a series of cokeovens arranged side by side in a group, a track supported above the ovens, a truck movable along said track above the oven ends, a rotatable drum supported on said truck, a chain secured to said drum and adapted to engage the oven-doors, a longitudinally-movable device, as chain f, lying parallel to the track, means for moving said device and a chain wound on the drum and connectible at will with the different points in the longitudinallymovable device aforesaid.

In witness whereof I have hereunto set my hand, in presence of two witnesses, this 5th day of April, 1895.

GUSTAV IIILGEN STOCK.
