To all whom it may concern:

Like letters of reference d enote corresponding partsin all the figures.

This invention relates to hydro-pneumatic motors for operating machinery of any kind, and consists in a novel combination of a water Wheel, an upper water tank or feeding reservoir, a lower discharge tank or receiving reservoir, and a vacuum apparatus adapted, by atmospheric pressure, to lift a column of water from the lower to the upper reservoir, whereby I construct aprime mover, which may be used for turning a shaft, and thereby impart motion to machinery, in the same manner as a steam-engine or any other form of prime mover, but at a greatly reduced cost as compared with the expense of running a steam-engine, electric motor, or any other form of artificial power now in use, which, directly or indirectly, depends upon the. consumption of coal or other fuel to furnish th motive power.

Referring to the drawings, the letter A denotes the base of the machine, which forms a shallow tank, B, and supports two pillars, O O, the upper ends of which are provided with journal boxes, D D, in which the main shaft, E, of the over-shot water wheel F is journaled. At one end of the tank is a raised platform, G, upon which is erected a tall hollow cylinder II, the lower part of which, resting on the platform, forms a furnace or fire-chamber, I, having an opening or inlet J, closed by a hinged door K. The opening J is encircled by an annular rim or flange J, the face of which is ground perfectly smooth and even so as to form an air-tight joint or closure with the hinged door K. Or, if preferred, the aunular rim J may be provided with an elastic packing or gasket of asbestus or other elastic material that will resist the action of heat, so

that the inlet J will be closed practically air- 7 ing h, which may be closed practically airtight by a valve M, sliding in the parallel ways m m, and articulated by a short connecting-rod n to an arm N, the other end ,of which is fastened at right angles in an upright shaft 0, inserted through avertical tubu-. lar bearing 0 on one side of the air chamber, H and passing through the bottom of the water tank L.

On one side of the air or vacuum cylinder H, on the outside, is placed a vertical water pipe P, the lower end of which dips down into the lower tank or reservoir B to within a short distance of its bottom, where it is provided with a valve-chamber P containing an automatic valve p, adapted to be lifted from its seat by pressure on the under side, so as to open the inlet to pipe P from tank 13. The upper end of pipe 1? passes through the bottom of and opens into the enlarged air chamber H, between it and the annular water tankL, In the bottom of the enlarged annular air chamber 1-1 is a pipe, Q, which extends into the water tank L, where it is bent upwardly at right angles to form an elbow, the enlarged upper end Q of, which forms a seatfor the gravity-valve q.

At one end of the water tank L is a pipe L, having a cock, Z, for controlling the outflow of water from the tank onto the buckets of the overshot water wheel F; the water being discharged from the buckets of the wheel, as this revolves, into the bottom tank or receiving tank 13. Upon the main shaft E, which revolves with the water wheel, and constitutes the main drive-shaft of the motor, is a pinion 1', which meshes with a cog wheel R, the shaft S of which is journaled in boxes, 8 s, supported by short posts or hearings on the platform G. Upon the revolving shaft S are keyed, or otherwise fastened, two cams, T and U, one of which (T) operates the intermittent igniting device, while the other (U) works the intermittently operating door K and topvalve M, as follows: At one end of the platform G is hinged, at g, a vertical arm V,

which is forced by a spring, 1:, against the cam T, so that its tappet or projection V will bear at all times against the periphery of the cam. To the upper end of this hinged arm V, above its tappet, is articulated a rod W,

the farther or free end of which forms a toothed rack, WV, the smooth side of which plays horizontally in a stationary-guide to, while its toothed side engages a pinion or on the tubular stem X of the igniter. This device consists of a vertical tube, the upper end of which is pivoted in an arm or bearing which projects laterally from the vertical air cylinder H, while its lower end (see Fig. 9) extends loosely down into the oil reservoir X, below platform G, through an openingin the top of said reservoir, so that a reciprocatory rotary motion may be imparted to the vertical tube X. On one side of this tube is a projecting tubular finger, Y, through which the wick Y projects; the lower end of the wick dipping into the oil reservoir X. The wick-tube Y is so bent and arranged that, when the door K of the air or vacuum cylinder H is opened, it will, by the part-revolution of tube X, be projected with its free end through the openingJ into the furnace-chamber I in the lower end of the cylinder, as

shown in dotted lines in Fig. 13. In other words, this tubular finger Y, with its wick Y (which is kept constantly ignited) forms the burner of theig iting device,.which is supplied with oil it L the small tank or reservoir X. The latter has, a tube Z, terminating in a small funnel 2, through which it can be replenished with oil when desired. As the jet offlame need not be larger than the jet of an ordinary cigar lighter, even in a full-size working machine of the largest capacity, a very small quantity of oil is consumed by the constantly burning igniting de vice. If desired, gas may he used for this purpose instead of oil or other liquid fuel. As cam T revolves, its periphery will bear against the spring-actuated tappet V until the cam-recesst is reached, when spring 0 will force arm V in the direction of the arrow shown in the detail views, Figs. wand 11, thus turning the vertical igniter stem X in its bearings so that the end of the burner Y will he suddenly projected through the now open door into the fire-chamber or furnace I, which results in the ignition of a batch of tow or cotton-waste, a, saturated with naphtha, kerosene, or some other highly inflammable hurn ing fluid. The burner is then immediately withdrawn again by the rounded part of the cam T striking the tappet V, so as to pull upon rod W and its rack W, which partly rotates the vertical igniter-tube back intoits normal position so as to quickly withdraw finger Y from the furnace. it will be seenthat the cam T,in conjunction with the springectuated arm V, rack W'- and pinion so, operates to intermittently project the ignited burner Y through the open door into the furnace or fire-chamber in the bottom of the vacuum cylinder H, Where it is kept for an instant only (just sufficient to touch and ignite the inflammable material with which it comes in contact), after which it is again immediately withdrawn, at the same instant as the air-tight door K is closed. The intermittent opening and closing of door K is effected by the other cam U, which also intermittently, and simultaneouslytherewith, opens and closes the air-tight top valve M, in the following manner: Against the periphery of cam U bears an arm, I), hinged at its lower end upon a stud, c, projecting laterally from the platform G, and pressed against by a spring d; i. 6., this spring (Z forces the free end of arm?) against the peripheryof the cam, so that its tappet b will always be in contact with the cam. To the upper end of arm bis articulated a rod 6, the other end of which is hinged to an armf, fastened to and extending laterally from the vertical shaft 0; said shaft being stepped at its lower end, movably, in a bracket or hearing, G, which projects laterally from the platform G, while its upper end, after passing through the tubular guide or hearing, 0, has fastened to it, at right angles, the arm N which operates the slide-valve M at the top of cylinder H. It will thus be seen that when rod 6 is pulled upon, by the lip u of cam- In other words:

, rod 6, tilt or partly rotate rod so as to again and simultaneously close both the door K and the top air-valve ill. And the position of the two cams T and U upon shaft S, relative to each other, is such that the movements of door K and'valve M are so timed that both will open at the precise moment when the ignited burner Y of the igniting device is projected into the fire-chamber I. In other words: at the precise moment-but at no other time-when door K and valve M are thrown wide open by the operationof cam U and its adjuncts, cam T will-through the intervention of arm V, tappet V, rod W, rack W, and pinion B-Pl0j80l3 the burner Y into the furnace through the open door. The next instant, the burner is withdrawn by the re- 6),

turn-stroke of rack W, and, simultaneously with the withdrawal, the door K and valve M are closed air-tight, and kept so closed until, on the next revolution of the operating-cams T andU, this performance of opening the door momentarily for the ignition of the inflammable material a, shall be repeated. At some convenient point (in the present instance, adjacent to and near the lower end of the air cylinder), is located a supply tank or reservoir, A, for supplying naphtha, oil, or other liquid fuel to the fire-chamber or furnace I;

' the flow of oil being regulated by a valve a.

In order to prevent splashing of water from the bucket wheel during the revolutions of the same, when the motor is used-in-doors, I provide it with a shield, B, which will defleet the water as it escapes from the buckets down into the shallow receiving tank B.

Having now described the construction of my motor, I shall proceed to describe its operation, which is as follows: A suitable quantity of cotton waste, tow, or other inexpensive inflammable and absorbent material,is thoroughly saturated with naphtha or kerosene and placed in the bottom of the fire-chamber I in the lower part of the air or vacuum cylinder H, as shown at a. The supply tank A is filled with oil, or whatever other .kind of liquid fuel it is desired to use, and the tank B is filled with water, level, or nearly so, with the under side of the bucket wheel, so that the valve chamber P at the lower end of the vertical water pipe P will be sub air-tight by a closely-fitting plug or stopper a I insert a lighted torch or taper, thus igniting the inflammable material a, after which the aperture a is closed immediately by reinserting the stoppingplug a The dash of flame produced by the ignition of the material a, partly consumes and partly ex pels, through the open top of the cylinder, the atmospheric air within the cylinder and its connecting annular air chamber H, thus creating a partial vacuum in these parts and also in pipe P, which, as we have seen, opens up into the annular air chamber H at the upper end of cylinder II. This vacuum causes the water in tank B, by atmospheric pressure, to open valve 10 in the submerged valve-chamber P and rise through pipeP up into the airehamber H, from which it escapes through the elbow pipe Q Q and its valve q out into the upper annular water tank L. Meanwhile, and while this takes place, the water wheel F has been started by pouring a, for that purpose sufficient, quantity of water into the upper tank L, which runs out through pipe L (the cock or valve Z of which hasbeen opened); so

that before all the water in tank L has run out, a fresh supply of water has been fed up intothe upper tank from the bottom tank through pipe P, chamber H and the elbow Q. The motor having now been fairly started, it will, by the hereinbet'ore described combination of cog-wheels, cams, tappets, and other cooperating parts, automatically and intermittently open the door K and valve M, to permit of the ignition, by the intermittently-operating igniting device, of the inflammable material a placed in thefire'chamher I, which is again immediately extinguished by the automatic and intermittent simultaneous closing of the door K and the upper air-valve M. In this manner, a suceession of flashes will be produced in the fireehamber I and air cylinder H, resulting in an intermittent vacuum in cylinder H and its connecting air chamber H at each of which periods a volume of water will be drawn up (due to the pressure of the atmosphere on the water in tank B) through the vertical pipe I and fed into the water tank L, from which it escapes through pipe L over the wheel F back into the bottom tank 13. The same volume of water maintains this circuit as long as the motor remains in operation, which will be as longas the fire-chamber is kept supplied withliquidfuel. Itisnotintendedthatthecotton waste or other absorbent material, a, shall burn; but this is merely intended as a wick or absorbent for the naphtha, oil, or other liquid fuel, which is supplied to the fire-chamber as occasion requires from the supply tank or reservoir A. As the ignition lasts a moment only, merely long enough to create a flash of flame up through the vertical cylinder, after which the flame is immediately extinguished by the automatic and simultaneous closing of the air-tight door K and -valve M, only a very small quantity of fuel will be consumed at each ignition and flash,

time, even with the largest size motors. The wick Y of the ignitingdevioe is, on theother hand, kept constantly ignited and notsuffered to go out; but as this is a very small jet of flame (not larger, as I have already stated, than the flame of an ordinary cigar lighter) the consumption of oil by theigniter is merely nominal.

Upon the main shaft E may be secured a pulley (or cog-wheel) E for operating the machinery which is to be driven by the motor; said shaftEconstituting the main drive-shaft of the motor in its capacity of a prime mover.

It will be obvious that I am not limited to the use of an overshot water wheel, but that other forms of water motors are equally well adapted to my purpose; for example, a turbine may besubstituted for the overshot wheel, if desired. Nor do I confine myself to the precise construction and arrangement of details as herein specified, as, for example, the form of the igniting device, and the mechanism-for operating it, may be varied in different ways without departing fromthe spirit of my invention." It will also be obvious that any suitable liquid (for example, a mixture of water and glycerine, or water and alcohol, to prcventfreezing incoldclimates) may be used for running the bucket-wheel, instead of water.

Having thus described my invention, what I claimas new, and desire to secure by Letters Patent of the United States, is
