CHARLES E. MARSHALL, OF LESTERSHIRE, NEW YORK, ASSIGNOR TO EMPIRE MOTOR &
MACHINE COMPANY, OF BAINBRIDGE, NEW YORK.
ROTARY FLUID-MOTOR;
Specification of Letters Patent.
Patented June 30, 1908.
To all whom it may concern:
Be it known that I, OHARLEs E. MAR- SHALL, a citizen of the United States, residing at Lestershire, in the county of Broome and State of New York, have invented certain new and useful Improvements in Rotary Fluid-illotors, of which the following is a specification.
The objects of my invention are to furnish a greater power from a small stream of fluid at a given head than is now furnished by other wheels. and motors; second: to furnish an adjustable means connected with the mountings of the wheel itself for regulating the distance of contact and angle of contact between the applied stream of fluid and the wheel. And I do hereby declare that the following is a full clear and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, and which form apart of this specification.
The nature of my invention consists of an arrangement of a motor wheel with an ad justable connecting nozzle, to conduct the fluid to the wheel, as will be hereinafter more fully described.
Figure 1 is a view of the vertical side of the wheel taken on the line 11 of Fig. 2. Fig. 2, is a partial sectional plan on line22 of Fig. 1.
In my invention I provide an outer casing A which may be of any suitable shape and construction. I attach to this casing a nozzle B which is mounted in a block O, and having slotted extensions O and O to enable the nozzle thus held in the block to be adjustable in its position and to be accurately adjusted at a proper distance from the wheel D and thus regulating the angle and form of contact between the applied liquid flowing through the nozzle and the buckets of the wheel.
Mounted within the casing isthe wheel D. This wheel has two flanges D and D and between which are mounted several buckets E, E, E, E etc, each of which is so curved and angularly disposed and situated that when the fluid issues from the nozzle B it will strike said buckets E, E, E etc. and cause the wheel to revolve; the centrifugal force will cause the fluid to keep in contact with said i buckets until all the energy of the fluid is spent, when it falls through the outlet of the case at the point F. The above operation from the flow of the fluid continues as long as the wheel is moderatelyburdened, but when the work it has to do becomes heavier the speed of the wheel will decrease and the fluid will then strike the buckets E, E, E etc. and be deflected therefrom on to the supplemental buckets E, E, E, etc. thereby the fluid thus acting on the wheel causes it to turn with a proportionate increase of power.
The outer series of buckets are curved and inclined inwardly from the periphery of the wheel, and they taper from a comparatively heavy or thick inner portion to a thin outer edge at the rim of the wheel. The inner series of buckets are also curved and disposed substantially opposite to the respective buckets in the outer series, the inner buckets being set at an incline substantially opposite to the incline of the buckets of the outer series so that the buckets of the two'opposite series are arranged in flaring relation to each other.
It will be noticed that the buckets E and E etc. are curved, thereby directing the course of the fluid from the one to the other, until the energy of the fluid is spent as above statedthereby preserving the energy of the fluid until the last amount of fluid is spent. It will be observed that the fluid strikes on the bucket at a point where it is nearly parallel with the course of the fluid, thus removing to a great degree the possibility of shock or the breaking of the fluid. Then the bucket moving in a circle, carries the fluid with it, the wheel traveling slower than the fluid, and thereby receiving a cer tain amount of the power of the fluid, and without breaking up the fluid or causing back action against the wheel; at the same time the wheel has turned a part of the way round. It will be observed that though the fluid is moving much faster than the bucket which it first came in contact with, yet the fluid must remain on this bucket until the bucket has passed a portion of the way around' this circle; by observing the position of this bucket, it will be seen that in operation the bucket has gradually changed its position and the course of the fluid has i an improvement on a patent granted the been practically reversed and in doing so the wheel has gained all the power that any wheel could gain by reversing the course of the fluid, once. It will be further observed that from the shape 'of the bucket, the bucket itself has retained the line of contact of the fluid, the same as it was when it entered. the wheel. When the fluid traveling faster than the wheel, is projected from the bucket of first contact, it goes directly against the inner set of buckets with all the force that still remains in the fluid, and should the fluid still retain a motion greater than the wheel, the fluid will again project itself against the outside set of buckets and so on be used indefinitely until the motion of the fluid is brought to the motion of the wheel. At this time the direct power of the fluid has all been taken from it. And at which time it will be observed, the contact of the fluid with the buckets on leaving the wheel, is such, as to give to the wheel, the action of a re-action wheel; and at which time the wheel will receive an impulse from the fluid, even though the fluid is traveling slower than the wheel, having received practically all the power of the fluid. Thus by this repeated action on the wheel of the same stream of water, by means of the two sets of buckets, there arises a proportionate increase of power, and also steadiness of motion.
I will further state that this invention is undersigned, March 4th 1879, No. 212,960 and the claimant does not new claim any parts covered by said former patent. It will be further observed that with its double line of angularly disposed buckets as herein arranged, and with its adjustably connected nozzle, said wheel can be operated successfully either with or without the case A.
Having thus fully described my invention what I claim as new and desire to secure by Letters Patent, is
The water wheel herein shown and described comprising the flat casing having one of its upper corners set at an incline and hav ing a longitudinal slot in such flat inclined portion, an outlet at the diagonally opposite corner of the casing, a nozzle block having a flat inclined base for engagement with the inclined surface of the' casing and having slotted opposite base extensions, bolts passing through said slotted base extensions to secure the block in place, the block having an angularly arranged bore therethrough and a nozzle engaged in such bore and projecting through the slot in the casing, a wheel journaled in the casing comprising a solid central portion and side flanges extending outward therefrom, the end of the nozzle being pointed substantially at an angle parallel to the rim of the wheel and lying adjacent to such rim, the central portion of the wheel having concave angularly disposed buckets formed therein with convex steps joining the outer edge of one bucket to the inner end of the next adjacent bucket, a series of outer buckets or paddles angularly secured between the side flanges with their outer edges in line with the rim of the wheel, said paddles having a sharp entrance edge and blunt inner edge, the outer buckets being longer than the inner buckets, disposed substantially opposite the same and arranged on converging lines with respect thereto.
In testimony whereof I have afliXed my signature, in presence of two witnesses.
