WATER OR IMPACT MOTOR.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed April 14:, 1905- Serial No. 255,515.

To all whom it may concern:

' Be it known that I, BRADFORD H. DIVINE, of Utica,- in the county of Oneida and State of New York, have invented certain new and useful Improvements in Water or Impact Motors; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form part of this specification.

The object of my present invention is to provide improvements in the construction of water or impact motors whereby provision is made for economical and rapid production of the same in quantities, and certain advantageous results are secured, as will hereinafter appear.

In the drawings, Figure 1 shows, in part, a side elevation with the cover removed and certain parts in section of my improved motor shown in connection with a faucet, to which it is attached. Fig. 2 shows a vertical section of the motor, taken on a plane at right angles to the plane of Fig. 1 of the drawings. Fig. 3 shows in sectional detail portions of the construction and more particularly the nozzle. Fig. 4 shows in perspective the main disk of the impact-wheel. Figs. 5 and 6 show perspective views in two positions of one of the blades employed in the wheel. Figs. 7 and 8 show a modified construction of impact-wheel.

Referring to the reference letters and figures in amore particular description, 1 indicates the casing of the motor, which includes on one side only a laterally-projecting hub 1. At the opposite side of the casing (which is formed as a single casting) from that having the bearing-hub 1 there is provided a circular opening 2 of sufiicient size to permit the passage of the motor-wheel when assembling or taking apart the construction, which opening 2 is adapted to be closed by a removable cover 3. At the lower side the casing 1 is more particularly pointed out. The outer end of the nozzle 6 is preferably provided with a shoulder and a loose nut 7, having internal threads by which the device may be readily attached or secured to a common faucet, as A. The shaft 8, as before suggested, has a bearing in the hub 1 and has secured on what may be termed its inner end the disk 9 of the impact-wheel. This disk is preferably provided with a hub, as shown, and particularly with a set of holes, as 9*, in pairs, which holes may be cast in and thereby produced economically.

The impact-blades 10 consist -ofa shank portion 10, having a pair of suitably-spaced and integrally formed rivets 10 provided thereon, and the head part 10, having a pair of cup-shaped depressions in the face side thereof. The blades 10, with their rivet parts 10 are of such shape that they can be cast complete, and thereby produced very economically. The blades 10 are secured on the disk 9 by inserting the rivet parts 10 in the opening 9 and upsetting or heading the rivets. This operation can be performed very expeditiously, and thereby the impact-Wheel, with its numerous blades, produced at a minimum cost.

The arrangement of the nozzle 6 with reference to the blades 10 is such that the stream delivered by the nozzle will strike the impactwheel tangentially and strike the face side of the head 10 on the rib which separates the two cup-shaped cavities in the face side. In so striking the heads of the blade the stream is split or divided and thrown off to each side, whereby the full benefit of the impact is secured and the water is dissipated sidewise in such a manner as to not foul the wheel after its energy has been taken.

It will be noted that the relation of the impact-wheel and the casing is such as to provide a considerable amount of clearance on all sides of the wheel, except at the nozzle, for the escape of water after it has acted on the wheel.

The outer end of the shaft 8 will preferably be provided with a fixedcollar 11 and a removable collar 12, between which any suitable wheel, as an emery-wheel 13, may be clamped. The inner collar 11 is preferably secured on the shaft by being threaded thereon, whereby it may be removed when it becomes necessary, while the outer collar 12 will have an opening unthreaded which will slip freely over the screw-threaded end of the shaft and be forced to clamping position by means of a nut 14, applied to the outer screw-threaded end of the shaft. The middle portion of the shaft in the bearing may be slightly reduced, as shown, whereby the shaft has bearings at each end only, and a cavity is provided which will retain oil or other lubricant to better advantage.

In the modified form of wheel shown in Figs. 7 and 8 the wheel-body 15. blade-arms 16, and blades 17 are cast integral. In order to enable the wheel to be cast cheaply and conveniently and the cup-shaft cavities secured in the blades, the same are first cast in the position shown by blades a a, facing laterally, and after which the arms 16 are twisted, being malleable for that purpose, to bring the blades into the position shown at Z) 6 at right angles to the plane of the disk part, beingin the mesial plane. By thismethod the impact-wheels are very cheaply and perfectly produced with a minimum amount of them to come into general use or become generally popular. Further than that, they need to be so simple in construction that they can be readily assembled and taken apart by a comparatively inexperienced person without danger of becoming disarranged or wrongly assembled.

The motor herein shown and described is believed to meet the above requirements in a very full and complete way.

WVhat I claim as new, and desire to secure by Letters Patent, is

A wheel for impact-motors consisting of a body, integral radial malleable arms and cupped blades on the end of the arms, the arms being twisted to turn the blades from a position facing laterally to a position facing the mesial plane of the wheel, substantially as set forth.

In witness whereof I have afiixed my signature, in presence of two witnesses, this 11th day of April, 1905.

BRADFORD H. DIVINE.
