- FLUID-MOTOR.

Specification of Letters Patent.

Patented Aug. 25, 1914.

Application filed. March 21, 1913. Serial No. 755,998.-

. To all whom it may concern:

Be it known that 1, JOHN M. CHRrsrorFEL,

a citizen of the United States, residing, at

Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented; certain new and useful Improvements in Fluid- Motors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 6

This invention relates particularly to fluid motors and has particular reference to new and useful improvements in that type of water wheel known as bucket rotors.

, As its principal object .this invention aims to increase the efficiency of bucket water wheels by providing a simple and practical motor designed with such regard to'proportion, number and arrangement of parts that the-waste of pressure and the power transmission is guarded against by successively impinging each unit of fluid volume against a number of rotor buckets.

A still further object of this invention contemplates the provision of a light andeflicient fluid motor which may be readily attached to any standard form of water spigot or hydrant.

The above andadditional objects are accomplished by such means as are illustrated in the accompanying drawings described in the following specification and then more particularly pointed out in the claims which are appended hereto and form a part of this application.

With reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throu hout the several views of which similar re erence numerals designate corresponding parts: Figure 1 is a side elevation of the motor illustrated in assembled relation to a water faucet, parts of the casing being broken away to more clearly disclose the assembled relation of the interior parts. Fig. 2 is an edge view of the rotor showing the buckets in section. Fig. 3 is a modified form of the elements illustrated in Fig. 2. Fig. 4 is a section on the line 44 ofFigpl.

Fig. 5 is an additional modified form of the features illustrated in Fig. 2. Fig. 6 is a detail view in perspective of one of the bucket baflie cores. Fig. 7 is a transverse sectional view taken on line 77 of Fig. 5. Fig. 8 is a detail. perspective of one of the buckets in dissembled position.

Proceeding now to the description of the drawings, the preferred form of my invention includes a motor casing 1, provided with the customary tangential internal screw threaded attaching nipple 2, and an outlet port 3. Keyed on a concentric shaft 4 jour naled at diametrically opposed openings in v the walls of the casing 1 is the rotor of my lnvention which includes a rotor disk 5 on the periphery of which is formed a double tional diamond-shaped baffle core 9. The .bucket casings 8 are preferably made of sheet metal of any suitable nature and are formed in the nature of cross-sectionally U-- shaped casings, the side walls 10 of the casing being directed inwardly and angularly at their lower end, producing a substantially funnel-shapedescape port for each bucket.

In mounting the bucket casings 8 on the flange 6 it has been found desirable to pro vide the flange 6 with spaced grooves 7 disposed to receive the curved edges 11 of the casing. Each of the buckets 8 are preferably provided with centrally'located apertures 14, the use of which will be more fully hereinafter described. The area of the surface of the bucket casings 8 immediatelyadas a supportvfor the core 9. The bafiie core 9 is made preferably hollow, and it is important that said core be diamond-shaped in cross section as will be hereinafter disclosed. The inner edges of the member 9 are curved to correspond with the curvature of the flange 6. The battle core 9 is formed of a single sheet of metal bent to form preferthan the casing. The inner edges 20 of the core are adaptedt'o conform to the curvature of the rotor 5. In assembling the entire bucket. the member 9 is mounted in the desired position on the outer face of the flange 6 and the casing 8 is mounted with its curved edges seated in'the grooves formed in the member 6, after which a bolt 12 provided with the customary head 13 is passed through a suitable apertured depression 14 formed in the front portion of the casing 8, the bolt being then directed through the member 9 and subsequently screw threaded into a suitable bore tapped in the member 5, as illustrated at 15 in Fig. 1.

In the modification of the bucket structure illustrated in Figs 3 and 5, it willsbe ob-- served that the one point of diflerence in the formation of the buckets resides in the fact that the angular relation of the converging portion of the walls 10 of the casing 8 and the angular relation of the sides of the baffle cores 9 is varied for a purpose to be hereinafter clearly disclosed.

. The actual structure of the 'motor being thus disclosed it now remains to describe the operation of the device and to enumerate the peculiar advantages resulting from the novel v bucket structure of this invention.

Briefly the operation is as follows: The water issuing from the nozzle of the faucet is ejected into the adjacent bucket striking the upper apex of the baffle 9, and the water being thus divided impinges first upon the upper adjacent walls of the baflle and then on the converging walls 10 of the casing. It will thus be seen that in each bucket'there are four oints of impingement for each unit of flu1d volume which is ejected into the motor. The utilization of the fluid does not terminate at this point, however, for as the fluid strikes the converging walls of the casing of the first bucket it is directed'against the upper diverging walls of the next adjacent diamond-shaped baffle, being thence deflected to impinge against the converging walls 10 of the casing of the second bucket.

Each unit of water is thus subjected to contact with a number of buckets 7, inasmuch-as the water will continue to act in rotatin the wheel 5 by pressure upon the buckets until'each volume unit has traveled through as many buckets as are necessary to absorb all of the incoming fluid. It will also beobserved that this peculiar design of bucket provides an effective means for absorbing and transformmg a maximum 'amount of water pressure a thepressure 1n the nozzle is increased. This feature is believed to be an essential. one and as such it is desirable that particular emphasis be laid upon it.

From the foregoing disclosures it is apparent that this invention rovides a simple yet eificlent fluid motor a ording maximum utilization of each pressure unit of the incoming fluid by permitting the stream of water to play successively upon a number of buckets. a

*In reduction topractice, Ihave found that the form of my invention, illustrated in :the drawings and referred to in the above descrip'tion,'as the preferred embodiment, is the most eflicient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the-fact that various minor changes in details of. construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as defined in the appended claims.

What is claimed is: 1. In a fluid motor, a rotor, a plurality of buckets mounted on said rotor, and a plurality of detachable bafiie members mounted within the buckets for deflecting a fluid injected therein.

2. In a fluid motor a rotor, aplurality of buckets mounted on said rotor, a plurality of detachable baflle members mounted within the buckets for deflecting a fluidinjected therein, and means for securing said baflle members to the buckets-and to said rotor.

4. In a fluid motor a rotor, a plurality of buckets mounted on said rotor, a plurality of detachable baflle members mounted within the buckets for deflecting a fluid injected therein, and screw threaded bolts passing through said buckets and the baflle members and engagin said rotor.
