WATER-POWER-OPERATED DEVICE.

Application filed December 29, 1924. Serial No. 758,554.

My invention relates to water-power operated devices of the type adapted to be attached to an ordinary faucet, or the like, and designed for operating household and other devices such as require rotary motion for driving.

An object of the invention is to provide a device of the character described which is arranged to permit a ready interchange or.

substitution of driven devices.

Another object of the invention is to pro vide a device of the character described which may be adjusted to enable the driven tool or implement to. be held in and operated at any desired angle.

A further object of the invention is to provide a device of the character described in which some of the motor parts while being of a comparatively intricate and highly technical, though eficient design, may, nevertheless, be manufactured at a low cost.

A still further object of the invention is to provide a device of the character described which may be attached quite close to a wall without impairing the usefulness of the device.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of my invention which is illustrated in the drawings accon'ipanying and forming part of the specification. It is to be understood that I do not limit myself to the showing made by the said drawings and description, as I may adopt variations of the preferred form within the scope of my invention as set forth in the claims;

Referring to said drawings:

The device of my invention includes a water motor 8 preferably of the rotary impact type and arranged to be connected to a source of water supply under pressure. For household use the motor is usually connected directly to a faucet such as shown at 9 and is preferably so attached thereto as to firmly support the motor and driven device during the operation of the latter. As-here shown, the connection of the faucet and motor is effected by means of a coupling 13 fixed to the inlet pipe 14 of the motor and adapted for removable attachment to the discharge end 16 of the faucet.

The motor is provided with a casing 17 of generally semi-cylindrical form and a rotor 18 arranged within the casing andmounted upon a shaft 19 which is. disposed concentric with the arc of the casing. The casing is preferably formed of two stamped sections secured together by a lap seam 21 at their outer edges. The inlet pipe 14, as well as the discharge pipe 22 of the motor, is formed integral with casing and extends tangentially of the casing and the rotor. Arranged within the intake pipe and the coupling 13 is a nozzle 23. having a passage 2% which communicates with the coupling passage :26

and faucet orifice 27 and is arranged to direct a jet of water tangentially against the periphery of the rotor. The coupling is arranged to be removably secured to the faucet by suitable means such as set screws 28, and means are provided for securing the inlet pipe to the coupling so as to provide a sealed joint therebetween. Means are also provided, which in the present form of the invention are embodied in the securing and sealing means just referred to, for'allowing the motor shaft to be moved to and operated As here shown, such positioning of the shaft is provided for by enabling the motor as a whole to revolve about the common axis of nozzle and inlet passage and about the common axis of the coupling passage and faucet orifice The nozzle as previously explained is arranged to be securely fixed to the casing, and as illustrated in Figure 1, is provided adjacent its discharge oritice withoppositely disposed bosses 29 'havingreduced ends '31 which extend through, "perforations 32 formed in the casing, the

outer extremities of such ends being flattencd to preferably permanently secure the casing and nozzle together. Formed in the coupling is a bore 33 coaxial with the nozzle passage and in which the journal portion 34: of the nozzle is rotatably engaged. It will be clear that rotation of the nozzle in the coupling will cause the motor to revolve about an axis perpendicular to its shaft. To provide a sealed joint between the casing and coupling, the outer end of the inlet pipe is bent inwardly to form a circular flange 36 which is arranged to be clamped between a cylindrical collar 3'7 formed on the nozzle and a gasket 38 seated in a recess 39 in the side of the coupling. Rotation of a thumb screw l0 extending through the coupling and engaging in a threaded. hole 4-1 of the nozzle serves to vary the clamping pressure to which the flange may be subjected. It is to be noted that clamping the nozzle to the coupling serves to hold the motor in the desired adjusted position.

Rotation of the motor about an axis perpendicula'r to the one about which it may rotate by reason of the rotatable mounting of the nozzle, may be readily effected by temporarily loosening one of the set screws 28 and then revolving the motor structure around the portion of the faucet engaged in the coupling. It will now be clear that the motor shaft may thus be positioned and operatively held in any desired position.

The coupling, whose features of general application are being made the subject of a separate application Letters Patent, is provided with novel and extremely effective means for preventing leakage of the water between the coupling and faucet, by taking advantage of the comparatively high pressure of water due to the restricted passage of the nozzle. Formed in the coupling is a groove 42 in which is engaged a centrallyperforated diaphragm 43 preferably made of soft rubber and formed concave on opposite sides thereof. The end of the faucet is arranged to contact with one side of the diaphragm so that such side has a lesser area exposed to the pressure than the other side. In this manner pressure of the water in the coupling will at all times lend itself toward effectively sealing the connection between the coupling and faucet.

It will'be noted by referring to Figures & and 5 of the drawings that both the inlet 14 and discharge 22 are located at what may be termed the rear edge of the casing, and that the motor shaft is located well forward of such edge and intermediate the side edges of the casing. Furthermore, the intake and discharge are aligned and coaxial with an axis of rotation of the motor about the nozzle axis. In this manner even though the motor and device are positioned quite close to a wall their operation will not be interfered with, and their usefulness will not be im )aired.

(Swing to the fact that the discharge passage is directly aligned with the intake passage ancl tangentially disposed with respect to the rotor, a smooth flow of water through the casing will be assured, and, consequently, a more ellicient transmission of the force of the water to the rotor will result.

The rotor 18, with which the motor is equipped, is of the twin-bucket water-wheel type. Heretofore, it has generally been deemed impractical, on account of the large number and form of the parts involved, to manufacture this type of wheel for motors other than those of extremely large size. However, in accordance with my invention, such a type of wheel is provided by the use of but two disks, thereby rendering such type of wheel entirely practical with the small motor used in the present device. As clearly illustrated in the drawings the wheel or rotor comprises a pair of coaxial disks at and 45 perforated and spaced adjacent the center portion and held against each other between such portion and the edge portion 47. The disks are suitably secured together and said edge portions thereof are inclined from each other and cut and bent as clearly shown in Figures 6 and 7 to form circumferentially spaced vanes or buckets 18. The vanes of each disk extend transversely thereof and contact with the vanes of the other so as to define pairs of co operating vanes or what is usually known as twin buckets. The sides of the cups diverge outwardly and extend forwardly, and the adjacent or inner sides thereof meet and define an acute angle. In addition to functioning to transfer the energy of the jet to the wheel, the inner sides serve as a means of dividing the jet of water as it strikes the wheel, while the outer sides serve to deflect the water from the buckets so that it will not rebound on the buckets following.

Means are provided for enabling any one of a number of different devices to be operably connected to the motor or interchanged for another. In accordance with the foregoing, the shaft 19 upon which the rotor is mounted and with which it is fixed for rotation, is formed hollow, and one end 51 thereof is closed, as by a cap 52, and lies within the casing, while the other end 53 is open and lies without the casing. The shaft is rotatably mounted in bearings 5i and 56, the former of which is positioned in the side wall 57 of the casing and the latter is spaced outwardly from the former and is supported by a supplemental casing which encloses the outwardly extending portion of the shaft and is fixed to the main casing 17. Arranged to be removably inserted in the hollow shaft 19,-is a shaft 58,

with which each of the devices that are to be driven by the motor are equipped. It will, of course, be understood that the particular form and size of each shaft 58 will vary in accordance with the character and design of the device with which it is associated. As will be clear by reference to Figure 3, the inner end portion of the shafts 58 are made flat, or the like, so that when the shaft is properly inserted in the rotor shaft 19 which is correspondingly formed, the two shafts will operate as one. Frictional or other engagement between the flat or other portions .of the two shafts are preferably provided for, so that proper operative engagement may be maintained.

In Figure 2-, the shaft 58 is associated with a bufling wheel 60, and is operatively held in the cooperating shaft 19 for move ment with the rotor.

In Figure 1, a heater 61 is shown as having displaced the buiiing arrangement illustrated in Figure 2. The shaft 58, as here incorporated, is made rather long in conformity with the beating element 67 which is 'fixed thereon for rotation therewith. In this arrangement the shaft 58 is mounted in bearing portions 63 and 64 of a spider (36. The latter is also provided with arms 67 which are arranged to engage in openings 68 in the supplemental casing 55, to hold the spider against rotation with the shaft when the latter are operatively engaged. The casing 55 is preferably formed with nipples 69 which are adapted to engage in openings 71 in the arms to aid in releasably connecting the beater to the motor when the shafts are properly engaged.

The discharge 22 is provided with an extension 72 which is adjustably and rotatably mounted on said pipe, such mounting being of considerable importance for the reason that notwithstanding the fact that the motor may be rotated about a horizontal axis, the extension may be positioned with its discharge end lowermost in all positions of the motor. It may also be noted that since the motor is arranged to rotate about the axis of the discharge passage, no adjustmentother than that of the extension is required to insure the most direct discharge of the water in any position of the motor.

While I have shown and described the motor in connection with a beater and a buffer appliance it is obvious that a host of other appliances may be adapted for operation by the motor.
