EDWARD n. WARNER, or PELHAM Manon, NEW YORK, ASSIGNORTO vlc'roaraeenn, OFNEWYORKNY,

WA ER-Moron.

To all whom it may concern:

Be it known that I, EDWARD D. WARNER, citizen of the United States, and resident of Pelham Manor, in the county of Westchester and State of New York, have invented certain new and useful Improvements in W Vater- Motors, of which the following is a spec1fication.

The invention relates to water drlven motors in which a rotor is rotated by the action of a jet of water on the buckets thereof, and more able motors adapted to be operated by the flow and'pressure found in the water sup ply usually furnished for household and V analogous purposes, and designed for de veloping the power required for driving massage vibrators, polishing'wheels and the like, and the object of the invention is to provide an efficientmotor of this character, which shall be simple in constructlon, economical in operation'and particularly well adapted to serve efficiently with water-sup ply systems of widely different pressures.

Another important object is to provlde a rotor having its buckets so shaped and disposed as to utilize the force of'the water advantageously,'and a further object is to provide stationary vanes adapted 'toserve with such buckets and upon which the cur-' rent may'react to increase the power developed. V .7

A further object is to provide a coupling especially adapted for service with such motor for holding the tools or implements driven thereby and permit them to be readily attached or detached in substituting one for another.

The invention consists in certain novel features of construction and arrangement of parts, by which the above objects are attained, to be hereinafter described and claimed: 7 The accompanying drawings form a part of this specification and show an approved form of the invention Figure 1 is a vertical diametrical section, partly in elevation.

Fig. 2 is avertical transverse section through the casing and its attaching means, with the rotor shown in side elevation.

Fig. 3 is a perspective view of a socket adapted to receive a tool or its holder.

Fig. 4 is a perspective View of a spindle Application filed Febr uary 15,1918; seriai'n 'z aae particularly to that class of port-' Specification of Letters Patent. Patented Sept. 24, 19 18.

or tool holder adapted to be received held in the socket shown in the precedlng figure.

Similar numerals refer to the same parts in all the figures. v

1 is the shell or casing of the motor which may be understood to be in two'or more parts suitably joined as m venient and economical in manufacture, .to provide an internal recess of approximately circular form adapted, to inclose a rotor fixed on ashaft' 4 'extending axially through the casing and'recess and adapted to rotate in bearings therein. f At the top of the casing is a hollow neck 3. having means for attaching the casing to a faucet or'other device for .the discharge of water, and having an internal cavity; From the interior of the neck below the nlpple, extends an angularly arranged passage '10 adapted to deliver water in a jet to the, rotor. The latter comprises a circular ay be found condisk 5 having acentral conlcal boss 7 on its inner face, extending the full width of the recess from such face totheopposite wall of the casing. On the plane circular margin of the disk is a seriesiof wings or buckets 6 extending part way to such opposite wall,

preferably cast integrally with the casing,

line approxi-I fixed vanes 8,

extending inwardly within the line of the V buckets 6 and between their straight inner ends and the boss .7. The edges of the vanes 8 adjacentthe boss are curved to conform to the curve of the latter, and the vanes extend across the space between the buckets 6 and the wall of the casing carryingthe vanes.

The lower end of the casing is open, as at g), to provide a discharge orifice through which the water may escape unobstructedly after performing its work inthe casing, and the orifice may be of such size and form as may be best adapted for general service.

The overhung end .of the shaft 4 may be shaped as desired to receive any suitable extension thereof;

as shown n Fig. 1, it-is hole adapted to receive a pin by which a flexible shaft, as 12, see Fig. 3, may bejoined thereto. 7

At its free end the flexible shaft is joined at 11 to a cylindrical shell or socket 16 having a longitudinal slit or deep notch 13 terminating at 14 in a short laterally or circumferentially extending notch 15, forming a bayonet lock with a pin or lug 21 on a cylindrical tool-holder 22, adapted to be inserted in the socket 16 and held by'the engagement of its pin in the notch 15, and having a collar 20 serving as a stop to limit its insertion within the socket, and a spindle 19 adapted to receive a polishing wheel or other rotatable implement.

In the event of a T shaped slot being cut in the cylindrical shell or socket 16, it will be possible to rotate the combination in either direction 17 or 1 8. t The operation of the motor is as follows: Water entering the casing as a jet from the passage 10 strike the curved ends, of

the buckets hand by its impact forces the rotor and its shaft to rotate, as the bucket advances under such impact the velocity of the water lessens and it follows the straight portion of the bucket and is deflected thereby inwardly toward the center along the plane face of the disk and along the surface of the boss or cone 7 guided by the latter to the apex and into the space beyond the buckets where it arrives in a spent condition, out of the path of the buckets and is free to escape through such space to the discharge iopening 9. Thus constructed the motorwill perform at a high rate of chiciency but experiments indicate that the efiiciency may be increased by the introduction of the fixed vanes 8 upon which the water reacts as it is delivered inwardly and spirally upon the done from the buckets, and

escapes fully spent with all its energy imparted to the rotor.

Importance is attached to the space between the rotor buckets and opposite wall for permitting the spent water to escape freely and immediately after it has performed its work, and to the conical boss by which the water is led to such space at the center of the rotor where the rate of velocity is less and entirely out of the path of the rapidly moving buckets.

The fixed vanes may be omitted and other modifications may be made in the forms and proportions of the parts as found necessary or desirable in adapting the invention to various conditions of service.

I claim I 1 In a device of the character set forth, a casing having an interior recess, a passage leading thereto from a supply of water under pressure, and a discharge opening, a disk mounted to rotatein said recess, having aseries of buckets on its margin ar-c ranged to receive water from said passage, said buckets" having a width less than said recess to afford free escape of spent water to said opening, through the space thus provided, a conical boss on said disk within said series of buckets, and extending into such space, and a series of vanes on the in terior of said casing within said series of buckets and extending across such space, said vanes having their edges adjacent said boss shaped to correspond to the shape of the latter. 7

Signed at New York city, in the county of New York and State of New York, this 9th day of February, A. D. 1918.
