SPECIFICATION forming part of Letters Patent No. 637,135, dated November 14, 1899.

Application iiled March 30, 1899. Serial No. 711,140. (No model.)

T0 all whom, it may concern:

Be it known that I, GEORGE E. LASH, a citizen of the United States, residing at Elkhart, in the county of Elkhart and State of Indiana, have invented certain new and useful Improvements in Rotary 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.

This invention relates to motors which are designed to be run by water-power for operating display devices in store-windows and actuating light machinery-such as sewingmachines, churns, scroll-saws, iiy-fans, and the like. agent, it will be understood that any of the usual mediums-'steam or compressed airmay be used.

lSimplicity of construction, combined with efficiency, durability, lightness, economy, and ease of operation are some of the many ends sought to be attained in devising the invention, which consists, essentially, of the novel features, details of construction, and combinations of the parts which hereinafter will be more fully described, illustrated, and claimed.

In the drawings, Figure 1 is a central longitudinal section of a motor constructed in accordance with this invention for attaining the ends thereof. Fig. 2 is a detail plan section. Fig. 3 is a view in elevation of a bearing. Fig. 4 is a section on the line a: .fr of Fig. 3. Fig. 5 is a detail perspective view of a portion of the motor-wheel. Fig. 6 is a detail View of a bucket-blank. Fig- '7 is a detail section of the jet-nozzle.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The motor-wheel l is composed of a rim portion, spokes 2, and a shaft 3 and operates within a casing composed of a lower portion 4 and a cover or upper portion 5. This casing is preferably constructed of sheet metal, although any suitable material may be employed in the formation thereof. The outer portion of the cover 5 curves on the arc of a circle conforming to the periphery of the mo- While water is the principal motive tor-wheel, so as to economize in space. The cover is formed with an outer flange 6, which overlaps the sides of the body 4, and with a pendent fiange 7 to enter the upper portion of the body and prevent the splashing of the water upon the floor, ledge, or other support upon which the motor may be placed. An outlet 8, consisting of a short length of tube, is applied to an end of the body 4, and a hosepipe is adapted to be coupled thereto for conveying the spent water to the required point of discharge. Y

A nozzle 9 is applied to the peripheral portion of the cover 5 to one side of a vertical line and has a tangential arrangement, so as to cause the jet of water or other motive agent to impact against the buckets of the motorwheel and drive the latter, so as to utilize a maximum amount of the force or head of the jet. It has been found desirable to have the nozzle 9 adjust-able, so as to vary its tangential relation to cause the jet to impact against the buckets of the motor-wheel at any point between their inner and outer edges. rIhis adjustment of the nozzle is also beneficial, since it allows for variations of workmanship in the assembling of the parts, whereby the jet may be given any required inclination with reference to the motor-wheel; As shown, the curved or peripheral portion of the cover is formed with a semicircular portion 10, which projects outwardly therefrom 'and which has an elongated opening 11 formed therein through which the nozzle 9 passes. A semicircular iiange or stop 12 is applied to the inner portion of the nozzle and obtains a bearing against the inner face of the part 10 and prevents outward movement of the nozzle. A washer 13 is slipped upon the outer portion of the nozzle and is plano-concave, the concave side corresponding to the convexity of the part lO, so as to secure a snug fit thereagainst, and the plane surface forming a seat for the nut 14 to obtain a bearing against, said nut being mounted upon a threaded portion of the nozzle and adapted to clamp the part 1Q between the washer 13 and the flange or stop 12. Upon loosening the nut 14 the nozzle can be turned to vary its inclination and when properly positioned IOO is secured by retightening the nut. The washer 13 and fiange 12 are of such -relative lengths with reference to the opening 1l as to cover the latter at all adjustments of the nozzle within the range of its movements. The hose-pipe for conveying the water or other motive agent to themotor is adapted to be co-upled to the projecting end of the nozzle 9 in any of the usual ways.

Two-part journal-boxes are applied to the sides of the body 4 and receive the shaft 3. These boxes are fitted into notches or cutaway portions in the upper edges of the sides of the body and have their edge portions grooved or channeled, so as to receive the marginal portions of the body bordering upon the notches or openings into which the boxes are fitted. The lower bearing 15 is grooved or channeled at its bottom and side edges, and the upper bearing 1G is grooved at its sides only and is formed in its outer face with a longitudinal seat 17 to receive a key 18, by means of which the boxes are secured when in place. The edges of the key-seat 17 are undercut or inwardly beveled, so as to overlap the beveled edges of the key 18 and retain the latterin place. This key 18 is slightly longer than the width of the box, so that its projecting ends will come beneath the outer roll or fiange 19 of the body 4 and secure the box against accidental displacement. An endwise movement of the key will unseat it and permit the upper bearing 16 of each of the boxes to be removed when it is required to disengage the motor-wheel from its casing` for any purpose. The shaft 3 is prevented from endwise play by shoulders or collars 20, applied to or formed therewith and engaging withv the inner sides of the boxes. Corresponding shoulders or collars 21 are applied to the shaft and engage with the outer sides of the bearings, and the latter, being held between inner and outer shoulders and in turn being secured to the sides of the casing, serve to strengthen and brace the latter.

The rim portion of the motor-wheel is composed of a band and side rings 23, the latter being joined at their inner edges to the outer edges of the band 22 and forming aspace to receive audconline the jet of water in the operation of the motor. The buckets 24 subdivide the peripheral spaceinclosed between the band 22 and rings 23 and receive the impact of the water or other motive agent. These buckets extend square across the space, so as to receive the full force of the jet, and curve between their inner and outer edges, the curve being greatest on a medial line. The inner portions of the buckets are disposed, approximately, upon radial lines and the outer edge portions have a tangential disposition, thereby giving to the buckets a form which pockets the water impacting thereagainst, whereby the weight of such water is utilized in addition to the momentum for effective work in propelling the Wheel when the motor is in operation. The construction ofthe buckets is such that when the water reaches the lowest position it will discharge without impeding the forward rotation of the motorwheel. The buckets touch the band 22 at their inner edges and the rings 23 at their sides and may be secured to these parts in any desired manner. In the preferable construction the buckets are formed from blanks struck from sheet metal of suicient stiness and having a series of ears or tongues 25 along their edges to pass through openings 26, formed in the rings 28 in coincident relation with the ears 25, so as to receive the latter,l

said ears or tongues being bent after their passage through the openingsy26, so as to hold the parts in fixed relation. The blanks are curved between their inner and outer edges prior to their assembling. This construction admits of any bucket being removed and easily replaced when crippled or unfitted for further service.

The motor is light in weight and can be driven by a small water-pressure for operating, advertising, or displaying devices in store-windows and other places and can be utilized for operating light machinery gener-l ally, and when constructed for any particular purpose it is to be understood that various changes in the form, proportions, and minor details of construction may be resorted to without departing from the nature or sacriiicing any of the advantages of the invention.

Having thus described the invention, what is claimed as new is- 1. In a motor of the character described, the combination with a motor-wheel, and a casing therefor having a deflected or curved portion, of a nozzle passing through an opening formed in the deflected portion of the casing and adapted to be moved to any desired position with reference to a line drawn tangentially7 to the motor-wheel, and means applied to the nozzle and arranged to come upon opposite sides of the deflected portion of the casing to clamp it and secure the nozzle in an adjusted position, substantially as set forth.

2. In a motor of the character described, the combination with the motor-wheel, and a casing therefor having a deflected or curved offset portion, of a nozzle passing through an opening in the said curved oiset portion and having a curved iiange or stop to engage with the inner side of the said offset, a plano-concave washer slipped upon the nozzle and engaging with the outer surface of the aforementioned offset, and a clamp-nut mounted upon the nozzle for securing it in an adjusted position, substantially as specified.

3. In a motor of the variety set forth, the combination with the casing having an 0E- standing portion at its upper edge and having the latter notched, journal-boxes fitted into the notches and having their bottom and IOC side edges grooved to receive the marginal In testimony whereof I aiix my signature in presence of two Witnesses.
