FLUID MOTOR Filed March 20, 1931 Summer I RICHARD J.GLASS Patented May 10, 1932 PATENT OFFICE RICHARD J. GLASS, COLUMBUS, OHIO FLUID MOTOR Application filed March 20, 1931. Serial No. 523,974.

Thisinvention relates to water motors especially adapted for domestic and other uses.

, The object of the invention is to provide a simple and economical construction whereby the exhaust or outlet of the driving fluid is utilized as the power shaft for carrying a tool, as for example a grinding wheel. Other objects will appear from the disclosure here- 1n.

The invention is embodied in the example herein shown and described, the features of novelty being pointed out in the claims.

In the accompanying drawings Figure l is a central vertical sectional View with parts in full of the construction according to the invention.

Fig. 2 is a view looking at the right hand end of Fig. l with the two disks or plates removed so as to expose the vanes of the motor.

Fig. 3 is a sectional view of the motor without the base disk, said rotor removed from its case.

The motor case or housing includes a circular rim 5 from one edge of which is formed a tapered cone-like offset 6 terminating in a thickened portion 7, and to the other edge of which is attached a removable disk or closure 8.

Within the case is the rotor proper which includes a tapered portion 9 like the offset 6, said tapered portion 9 having its flared margin provided with a series of curved or cupped vanes 10 having their heels 11 thickened and turned slightly outward as respects the path of rotation substantially as shown. The wide end of the rotor containing the vanes 10 is shown as covered with a disk 12 that can be welded or otherwise secured at several points to the vanes around the rim of the rotor. Said disk 12 will rotate with the rotor and therefore avoid the friction of driving fluid with the stationary main clo sure 8. But the .rotor is operable without the disk 12. The end of the tapered portion 9 of the rotor proper has a thrust hearing at 7. Swaged or otherwise fixedly secured in the tapered end of the rotor is a pipe 13 constituting the exhaust. or discharge of the motor and at the same time providing a work shaft to receive a tool or other member with which to apply or utilize energy developed. Said pipe 13 is provided with a thickened portion 14 engaging the outer end of the portion 7 thereby, in conjunction with the bearing at 7, preventing any considerable axial movement of the rotor and its hollow shaft.

The pressure from an ordinary kitchen faucet can be utilized for driving the rotor and for this purpose the rim of the rotor case is provided with an internally threaded boss 14 extending parallel to a tangent of the rim of the rotor in which boss is screwed a nozzle 15 directed to about the middle of the cupped sides of the vanes when they stand successively at a right angle to the axis of the stream from the nozzle. The nozzle 15 is coupled with ordinary coupling to the threaded end of a faucet 16.

The discharge of the nozzle 15 is of smaller diameter than that of the exhaust so as to provide a free discharge and avoid back pressure due to accumulation of fluid in the rotor chamber.

In operation a regular swirl or vortex of the water is set up in the tapered lateral projection of the rotor which tends to accelerate the discharge of the water from the rotor chamber and through the exhaust shaft and thereby relieve the load of the impelling water and promoting the efliciency of the device.

The speed of the rotor can, of course, be controlled, varied or shut off by adjusting the valve of the faucet.

Any suitable tool for doing the desired kind of work can be secured to the body of the hollow'shaft or to the end thereof by means of a suitable thread at 17 thereon. Small space between the tapered portions of the case and rotor will prevent excessivepressure of the rotor on the hearing at 7.

The forms of the parts can be changed without departing from the gist of the invention as claimed.

Vhat I claim is:

1. A liquid motor including a. housing having a chamber including a circular portion at one end and a hollow lateral extension thereof of conoidal form, a rotor mounted in said housing in parallel relation thereto, said rotor including a hollow member, the interior surface of which is of conoidal form, said member provided at its base with a circular series of vanes to rotate within the circular portion of the housing, a nozzle in the housing for conducting liquid pressure to the rotor, and a hollow Work shaft constituting the exhaust of the motor, said work shaft fix'ed to the apex of the rotor and extending through the apex end of the taper portion of the housing.

2. A liquid motor including a housing having a chamber including a circular portion at one end and a hollow lateral extension thereof of conoidal form, a rotor mounted in said housing in parallel relation thereto, said rotor including a hollow member, the interior surface of which is of conoidal form, said member provided at its base with a circular series of vanes to rotate within the circular portion of the housing, a nozzle in the housing for conducting liquid pressure to the rotor, and a hollow work shaft constituting the exhaust of the motor, said work shaft fixed to the apex of the rotor and extending through the apex end of the taper portion of the housing, the diameter of the liquid pres sure nozzle being smaller than that of the rotor discharge.

3. A liquid motor including a housing having a chamber including a circular portion at one end and a hollow lateral extension thereof of conoidal form, a rotor mounted in said housing in parallel relation thereto, said rotor including. a hollow member, the interior surface of which is of conoidal form, said member provided at its base with a circular series of vanes to rotate within the circular portion of the housing, a nozzle in the hous ing for conducting liquid pressure to the rotor, and a hollow work shaft constituting the exhaust of the motor, said work shaftfixed to the apex of the rotor and extending through the apex end of the taper portion of the housing, said rotor having a closure fixed to the side thereof opposite that having said 4 hollow conoidal member thereof.

'4. A liquid motor including a housing having a circular rim from one edge of which, extends a hollow conoida shell having a hearing at its apex' a vaned circular rotor having a lateral shell extension, the interior of which is of conoidal form, said extension to turn in the conoidal extension of the housing but having its wall spaced therefrom by said lmaring, a nozzle in the housing for conducting' liquid pressure to the rotor, and a hollow Work shaft constituting the exhaust of the motor fixed to the apex of the rotor member and extending through the apex of the housing.
