APPARATUS FOR WETTING EMERY-WHEELS.

SPECIFICATION forming part of Letters Patent No. 707,420, dated August 19, 1902.

Application filed July 31, 1901. Serial No. 70,385- (No model.)

To all whom it may concern:

Be it known that I, ELWIN R. HYDE, a citizen of the United States, residing at Bridgeport, county of Fairfield, State of Connectiout, have invented a new and useful Apparatus for 'lVetting Emery-Vheels, of which the following is a specification.

My invention relates to the class of grinding-machines in which it is required thatthe grinding-surface of the wheel, more especially an emery-wheel, be kept moistened, but at the same time desirable that as little water as possible be picked up by the wheel. It is therefore desirable in this class of machines that the water in the tank be maintained at such a height that the lower edge only of the wheel will just touch the surface of the water, or at most be but slightly immersed therein.

My invention therefore has for its object to provide a simple, inexpensive, and easily-operated apparatus adapted to all ordinary styles of grinding machines, by means of which the water in the tank may by an occasional slight operation be maintained at any desired height in the tank-that is to say, slight attention to the machine and occasional action by the operator enables him to make good the loss of water from the tank through waste and evaporation.

With this end in view I have devised the novel grinding-wheel-wetting apparatus, of which the following description, in connection with the accompanying drawing, is a specification, reference charactersbeing used to designate the several parts.

The drawing is an elevation, partly broken away, to illustrate the construction and operation of my novel apparatus.

Adenotes an emery or othergrinding-wheel, whose shaft 13 is journaled in a suitable frame or casing C, which may be of any ordinary or preferred construction,necessarily, however, embodying a water-tank D. The grinding-wheel is ordinarily partly covered by a hood E, and a pan F is provided to catch any water that may be thrown outside of the hood.

My invention consists in providing a waterreservoir G, which in order to provide the l greatest capacity without its being in the way to the slightest extent and Without changing the design of the frame or casingI place under the tank.

(ldenotes the normal water-line in the tank, and H a pipe extending from near the bottom of the reservoir to approximately the normal water-line in the tank. In practice the frame or casing may have cast therein a horizontal Wall J to separate the tank of the reservoir, and pipe 11 may becast into this wall.

K denotes an air-pump, which may be conveniently placed, as upon a bracket L, cast integral with or rigidly secured to the frame. A pipe M extends from this air-pump into the reservoir at the top. A petcock N is provided in this pipe in order that air-pressure in the reservoir may be maintained should it be necessary to disconnect the air-pump.

0 denotes a faucet, which is provided in order to permit drainage and cleaning of the tank should it become necessary.

The air-pump may be of any ordinary or preferred construction, it being of course contemplated that the air-pump contain the usual valves to prevent the return of air. No pump need be described in detail, as the special pump used is not of the essence of my invention.

It will be obvious that by forcing air into the reservoir water will be displaced therein and will pass through pipe H to the tank, the operator being simply required When the Water in the tank drops down low enough so that the wheel will not be sufficiently wetted to operate the pump slightly and force sufficient water from the reservoir into the tank to raise the water therein to the desired height, it being obvious also that the water in the tank may be raised as high as may be desired by continuing the pumping operation. In order to fill the reservoir, the operator pours water into the pan, which passes to the tank and down pipe 11 into the reservoir. As soon as the reservoir is filled the water will of course rise above the normal waterline in the tank. Any surplusage of water in the tank, however, may be removed at any time by means of the faucet.

Having thus described my invention, I in the tank by displacing water in the resero1ai1n-- voir. to
