JOIIN WV. LAMBERT, OF ANDERSON, INDIANA, ASSIGNOR TO THE BUCKEYE MANUFACTURING COMPANY, OF SAME PLACE.

APPARATUS FOR COOLING ENGINE-CYLINDERS.

SPECIFICATIN forming part of Letters Patent No. 643,065, dated February 6, 1900.

Application led April 20, 1899- To all whom t may concern:

Be it known that I, JOHN W. LAMBERT, a citizen of the United States, and a resident of Anderson, county of Madison, and State of Indiana, have invented certain new and useful Improvements in Apparatus for Cooling Engine-Cylinders, of which the following is a specification, reference being had therein to the accompanying drawings, in which- Figure 1 is a side elevation showing a portion of an engine-cylinder, the cooling-tank, and the blower; and Fig. 2 is a vertical sectional view of the cooling-tank.

This invention relates to that class of apparatus covered by my former application bearing Serial No. 655,454; and it has for its object to provide certain improvements thereon which are hereinafter more fully described and are particularly pointed out in the claims appended.

Referring to the various parts by numerals, 1 designates a gas-engine cylinder which is provided with a water-jacket of any desired Leading from the top of the water-jacket upward to a tank 2 is a waterpipe- 3, through which the water which has passed through the jacket and become heated passesup to the tank. This tank is supported at a suitable height above the cylinder, and the pipe 3 opens therein through the bottom. Secured within the tank to the bottom thereof to register with the end of pipe 3 is a vertical tubular casing 4, which extends slightly above the water-level in the tank and is of substantially the same diameter as the pipe 3 and is practically a continuation thereof, the pipe 3 and the casing 4 forming the hotwater-conducting conduit. Carried by this casing at diametrically-opposite points are two upward-extending arms 5, which terminate above the water-level in the tank.

Surrounding the tubular Casin g and extending a short distance above the upper end is the inner end of the pipe 6, through which a blast of air is driven by a blower 6, operated by the engine or other suitable means, said pipe carrying at its upper end the outward and downward extending deflector-plate 7. Connecting together the upper ends of the two arms 5 is a bridge-bar 8, whose center Serial No. 713,807. (No model.)

portion is raised 'and lits closely within the cylindrical hood 9 and is permanently attached thereto, said hood being formed with the inverted conical top 10.

The tubular casing 4 is formed at its bottom with a bearing l1 to receive the lower end of the rotary-screw water-elevator 12, and the bridge-bar 8 is formed atits center with a bearing 13 to receive the upper end of this water-elevator, said water-elevator extending through the casing 4 and serving to lift the water in said casing over into the blast-pipe 6. Secured rigidly to the water-elevator just at the top of the blast-pipe is a small motor or fan-wheel 14, which receives the blast of air and is rapidly rotated thereby. A pipe 15 leads the cold water from the bottom of the tank to the lower portion of the engine-cylinder jacket.

In operation the water in the tank and in the tube 4 is at the same level when the engine is not running. When the engine is started, the blower is put into operation and a blast of air is forced through the motor-fan, thereby rotating it and with it the screw Water-elevator. AS this elevator is operated it lifts the water from the casing 4 over into the blast-pipe, from which it is blown up through the fan and into the hood 9. From the hood the water drops to the deliectorplate '7 and finally falls into the tank 2. It will thus be seen that positive means is provided for causing a rapid circulation of the water, the means for causing this circulation being operated by the blast which sprays and cools the water.

It will be observed that a feature which contributes to the utility of the apparatus lies in the fact that the blast of air carrying the overflowing water is thrown violently against the blades of the motor, whereby the water will be finely sprayed and intermittently commingled with the blast of air and thereby quickly cooled.

I claim- 1. In an apparatus for cooling engine-cylinders, or the like, the combination of a water-tank, a cool-water pipe leading from the tank to the device to be cooled, a hot-water pipe leading from said device to the tank and IOO extending up into the tank to near the Waterlevel therein, a blast-pipe entering the tank and terminating adjacent the upper end of the hot-Water pipe, so that the blast Will strike the Water as it overiows from the hot-Water pipe, a blower, an air-motor supported above the hot-Water pipe and blast-pipe, in the path of the blast, and a water-lifting device supported in the hot-Water pipe and attached to and operated by the air-motor, whereby the blast will take up the Water as it overiiows from the hot-Water pipe and spray it against the air-motor, for the purposes set forth.

2. In a cylinder-coolin g apparatus the combination of a cylinder and Water-jacket therefor, a water-tank, a hot-Water conduit connecting the jacket to the tank, said conduit extending near to the Water-level in the tank, a Water-elevating device with the hot-Watery conduit, a blast-pipe surrounding the end of the hot-Water conduit, means for causing a blast therethrough, and means wherebyT the air-blast will operate the water-elevating device to lift Water from the hot-Water conduit into the blast-pipe and the airb1ast will spray and cool the Water, said means for operating the Water-elevating device being supported in the path of the blast at the upper end of 'the blast-pipe, above the upper end' of the hot-Water conduit, so as to receive and break up the spray and commingle it with the blast.

3. In a cylinder-coolin g apparatus the combination of a cylinder and Water-jacket therefor, a Water-tank, a cool-Water pipe leading from the tank to the jacket, a hot-water conduit leading from the jacket to the tank, said conduit extending near to the Water-level in the tank, a blast-pipe surrounding the said conduit, a rotary Water-elevator Within the hot-Water conduit, means operated by the airblast to rotate said elevator to lift Water into the blast-pipe, said means consisting of an open air-motor to receive the impact of the blast and lifted Water and intimately commingle the same.

4:. In a cylinder-coolingapparatus the combination of a cylinder and Water-jacket therefor, a Water-tank, a cool-Water pipe leading from the tank to the jacket, a hot-Water conduit leading from the jacket to the tank, said conduit extending near to the level of the Water in the tank, a blast-pipe surrounding the hot-Water conduit, a rotary Water-elevator Within the hot-Water conduit, afan or similar air-motor secured to the elevator and operated by the air-blast, said fan being journaled or supported above the hot-Water conduit and in the path of the blast, whereby the lifted Water will be thrown against the fan-blades and break up the spray and commingle it With the blast.

5. In a Water-cooling apparatus, the combination of the device to be cooled, such as a gas-engine cylinder, a Water-tank, a cold-Water pipe and ahot-water pipe connecting said tank with said device to be cooled, said hotwater pipe extending to a point above the normal Water-level of the tank, a blast-pipe surrounding the upper end of the hot-water pipe and extending above the same, a Waterelevating screw j ournaled in the upper end of the hot-Water pipe, an air-1notor carried by the shaft of said screw at a point above the hot-Water pipe, in the path of the blast of air and hot Water, means for supporting the screw shaft, and means for returning thc sprayed Water to the tank, substantially as set forth.

In testimony whereof I hereunto affix my signature, in the presence of two Witnesses, this 18th day of April, 1899.

JOHN XV. LAMBERT.
