ORPORATION OF OHIO.

POWER-DRIVEN am it may concern:

own that I, OSCAR SUNDT, of Cleveiahoga county, Ohio, have invented useful Power-Driven Roller-Tach the following is a full, clear, and ription, reference being had to the :ying drawings, forming part of this ion, in which is a side elevation showing a pore roller-table constructed in acith my invention. Fig. 2 is a simin a larger scale, partly in sectibn. n artial transverse section; and Fig. plan View showing a modified form ratus for roller-tables used for stiff uch as bars, rails, dcc.

ntion relates to the driving of the eed-tables for rolling-mills, and is to provide a simple, cheap, and aged system for such purpose. ention consists, essentially, in pro raulic turbines upon the projectpf the rollers, which turbines are by valved supply pipes with a iquid under pressure.

or consists in providing eductionhe turbines, which convey the liq} ack to the source of supply, sothat circuit of the motive liquid is pronsists in providing step-down gearen the turbines and the rolls as ;the construction and arrangement ts, as hereinafter more fully ded claimed.

lead into the turbine-casings and are arranged to deliver the fluid to the turbines at the proper point. Each casing is provided with an outlet-pipe 11, these pipes leading to a common return-pipe 12, which extends to the entrance feed opening of the centrifugal pump. I have shown the rollers as spaced a considerable distance apart,with guide-plates 13 arranged between'them; but the number, size, and arrangement of the rollers may be varied widely within the scope of the invention. Instead of the centrifugal pump shown I may use a reservoir, into which the exhaust liquid is pumped and from which it. is fed to the turbines.

For using the system upon ordinary feedtables the turbines would give too high a speed to be practicable, and for such tables I use step-down gearing between the turbines and the rollers. Thus in Fig. 4 I show the protruding shaft of the roller as provided with a worm-wheel 14, intermeshing with a worm 15 on a shaft extending parallel with the axis of the table and to which shaft is secured the turbine-wheel 5' Within the casing 6'. The feed and exhaust pipes are arranged as in the first form, and the system is thus made applicable to ordinary feed-tables used for the supporting and conveying of rolled material.

The ad vantages of the invention result from the use of the liquid in connection with turbines, from the valved individual supplypipes, and the continuous circuit of the liquid. A simple, compact, and cheap system is thus afiorded by which the rolls may be driven at high speed, or at lower speed when the intermediate gearing is used.

Many variations may be made in the form and arrangement of the rolls, the source of liquid-supply, 850., without departing from my invention.

I claim r 1. A rolling-mill feed-table having a set of rollers, a set of driving-turbineaeach connected to a single roller, and a source of liquid under pressure having valved supplypipes leading to the turbines; substantially as described.

2. A rolling-mill feed-table having a set of till turbines each having an actuating connection with a single roller of the table, a source of fluid-supply having valved connections to the turbines, and exhaust connections leadingto the source of supply; substantially as described.

3. A rolling-mill feed-table having turbinedriven rollers, a source of fluid under pressure having a pipe extending along the turbines, valved branches leading from the supply-pipe to the turbines, exhaust-pipes leadfrom the turbines to a common return-pipe, and means for forcing the fluid back to the source of supply; substantially as described.

4. A rolling-mill feed-table having rollers, each roller having an individual actuatingturbine connected therewith by slow-motion gearing; substantially as described.

5. A rolling-mill feed-table having rollers, turbines connected with the rollers by slowmotion gearing, and mechanism for forcing the fluid in an endless circuit to and from the individual turbines; substantially as described.

6. A rolling-mill feed-table having a set of rollers, a set of driving -motors, each connected to a single roller, and means for varying the speed of each motor; substantially as described.

In testimony whereof I have hereunto set my hand.

OSCAR SUNDT.
