To a whom it may concern.-

Be it known that I, JOHN LOFTUS, a citizen of the United States, residing at Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Steam-Spray 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 same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in steam spray motor wheels, and the object of the invention is to produce an apparatus in which an expansive or elastic motor force, such as steam or compressed air combined with water, is utilized, and in which the steam is adapted to be condensed within the motor, thereby causing the formation of an expansive spray, the force of which is exerted upon spiral coils mounted within the motor wheel.

The invention consists in various details of construction and in combinations and arrangements of parts which will be hereinafter fully described and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which Figure 1 is a vertical sectional view through the motor made in accordance with my invention. Fig. 2 is a transverse section through the motor. Fig. 3 is a detail view looking at the edges of the spiral coils. Fig. 4 is a sectional view of a slight modification in which the spirals are cast integral with each other. Fig. 5 is a detail view of the hollow rim, and Fig. 6 is an enlarged detail view showing the manner of retaining the detachable coils from moving independent of the rim of the wheel.

Reference now being had to the details of the drawings by letter, A designates a hollow rim of the motor wheel which is connected by means of the spokes B with the hub B which is adapted to be fastened to a shaft B which may be mounted in suitable bearings, not shown. annular slot around its periphery, and the edges of the rim at such slot are formed into flanges B Said rim, which is hollow, has an.

O designates a suitable casing in which the motor wheel is mounted, and l) designates a guard plate which is made on the arc of a circle and is adapted to be held within the casing with its inner face adjacent to the marginal edges of the llanges of said rim. 6o Mounted within said rim are the two spiral coils, designated by letters E and F, respectively, the former of which coils is larger than the latter, and one coil being contained within the other. Said spirals are made preferably of a flat wire and are preferably inclined in the positions shown in Fig. 3 of the drawings. It will be understood that these coils may be detachably mounted within the rim or formed as an integral part of the rim. 7 In the former instance, in which the coils are detachably mounted within the rim, they are held from rotation independent of the rim, by any suitable means, such as eye-bolts H and H, shown clearly in the drawings. The 7 5 eye-bolts H are longer than the eye-bolts H and are adapted to engage the coils E, the

shank portions of the bolts passing through the rim and held by means of adjusting nuts it, while the inner coils are engaged by the eye-bolts H, which also pass through the rim and carry the adjusting nuts h, it being preferable to allow the inner coil to have a slight expansive movement incident to centrifugal force coming upon the same as the motor is rotated rapidly, and to allow for this expansive force of the inner coil, a slight play is allowed the bolts H.

K designates a steam nozzle, the tapering end of which passes through the wall of the 0 casing and also through an aperture formed in the guard or check plate D, and is set tangent to the motor wheel. A short distance behind the steam nozzle is a water nozzle N, alsopassing through an aperture in the 9 5 casing and said guard plate and tangent to the wheel. Leading from the shell is an exit C, and D designates a second guard or check plate which is mounted within the casing at one side of the discharge or exhaust i'oo passageway, a suitable space intervening between the corresponding ends oi the two guard or check plates. \Vhile I have shown the check or guard plates :[ixed permanently within the casing, if desired, they may be made adjustable. I

In Fig. 4 of the drawings, I have shown a slight modification of my apparatus in which the outer coil S and the inner coil S are cast integral with each other, being connected by suitable ribs S and in this modified form, the coils may be held in any suitable manner to the rim of the Wheel.

In operation, water either by gravity or pressure is first introduced through the water nozzle, and coming in contact with the coils, will cause the motor wheel to rotate. As steam is introduced through the steam nozzle and comes in contact with the Water in the coils, a rapid condensation of the steam will ensue, thereby forming a heavy spray having a high velocity, and the expansive force of the spray will be exerted against the coils underneath the check or guard plate, thereby exerting an increasing force up on the spirals. By this manner of introducing the water and steam, the water first exerts its power upon the motor, then, by partially condensing the steam, by introducing the same inv contact with the water, the heavy spray formed will be more effectual as a mo tor force than would the steam alone, and by introducing the steam and water independent of each other, the entire expansive force of the steam is exerted upon the coils of the motor wheel.

It will be noted that the guard or check plate through which the nozzles pass, extends-a'slight distance to the rear of the water nozzle for the purpose of avoiding air currents being carried into the coils by the action of water and steam therein, and affords a substantially closed passageway intermediate the guard plate and the coils in which the water and steam and also the expansive force of the spray may be exerted upon the two coils. It will be noted that the nozzles pass through the guard plate in close fitting holes so as to prevent the taking in of air which would have no power or beneficial effect. By the provision of a second guard plate, with open spaces between the two plates, means is afforded for the escape of the w ater and steam after the force of the same has been expended.

' It will be noted that in the construction of a motor made in accordance with my invention, the coils being acted upon by the expanding force incident to the condensing of the steam, a continuous combining tube, involving the principle of an injector, is afforded, whereby a powerful motive force is afforded for rapidly rotating the motor wheel.

That I claim is 1. A steam spray motor. comprising a rotatable wheel having a hollow rim, a casing for said wheel, spiral coils mounted Within said rim, nozzles passing through said casing, tangent to said wheel, and adapted to admit steam and water independent of each other to said spiral coils, as set forth.

2. A steam spray motor, comprising a rotatable wheel having a hollow rim, a casing for said wheel, spiral coils mounted within said rim, a guard plate mounted about a portion of said spiral coils, and tangentially disposed steam and Water nozzles passing through said casing and guard plate, as set forth.

3. A steam spray motor, comprising a rotatable wheel having ahollow rim, with an annular slot in the periphery thereof, spiral coils mounted Within said rim, a guard plate extending about a portion of said coils, a casing about said Wheel, and tangentially disposed steam and water nozzles passing through said casing and guard plate, as set forth.

4. A steam spray motor, comprising a rotatable wheel having a hollow rim, with flanges at the edges thereof which are spaced apart, spiral coils within the rim, a casing in which the Wheel is mounted, a guard plate mounted within the casing and held adjacent to the marginal edges of said flanges, and tangential steam and water nozzles passing through said casing and guard plate, as set forth.

A steam spray motor, comprising a rotatable wheel having a hollow rim, with flanges at the edges thereof which are spaced apart, spiral coils within the rim, and detachably held therein, a casing in which the motor wheel is mounted, a guard plate sup ported Within the casing and provided with apertures, and tangentially disposed steam and water nozzles passing through said casing and apertures of the guard plate, as set forth.

6. A steam spray motor, comprising a rotatable wheel having a hollow rim, with flanges at the edges thereof which are spaced apart, spiral coils of different diameters, one mounted Within the other, means for allowing the inner coil tohave an expansive move ment incident to centrifugal movement of the wheel, and means for preventing the coils from moving independent of each other, as set forth. I

7. A steam spray motor, comprising a rotatable wheel having a hollow rim, with flanges at the edges thereof which are spaced apart, spiral coils of different diameters, one mounted within the other, means for allow-- ing the inner coil to have an expansive move ment incident to centrifugal movement of the wheel, eye-bolts passing through the rim, a wire enga ing the eyes of said bolts and also said coi s, and nuts mounted upon said bolts, as set forth.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
