SPECIFIGATIONfOrfiiing part'of Letters Patent No. 487,584, dated December 6, 1892. Application filed April 4, 1892- Serial No. 42 7,675. (No model.)

To all whom it mag concern:

Beit knownthat I, BENJAMINS; PARTRIDGE, of J acksonville, in the county of Duval and State of Florida, have invented a new and Improved Motor, of which the following is-a full, clear, and exact description;

The invention relates to motors such as shown and described in the application for Letters Patent 'of the United States, Serial No. 399,511, filed-by me July 14-, 1891, and allowed January 4, 1892'.

The object of the invention is to provide a n'ewa'nd improved motor which is simple-and durable in construction, very effective in operation, and more especially designed for use on Artesian Wells or other devices to obtain, with alow pressureof water as a drivingmedium, a large amount of power for actuating other machinery.

The invention consists'of'ccrtain parts and details and combinations of the same, as will behereinafter described, and then pointed out in the claims.

Reference is'to'be had to-the accompanying drawings, forming a partiof this specification,

in which similar letters ofreference indicatecorresponding parts in all the figures.

- Figure 1 is a side elevation of theimprovement. Fig. 2 is a sectionalplan view of the same on the line:2 2 of Figs. 1 and 3. Fig. 3

isa sectional side elevation of the same-on the line3'3 of'Figs. 2 and 4. Fig. 4 is atransverse section of the same on the line4 4 of Figs. 2 and 4, and Fig. 5 isa face view of one of the valves.

The machinery to be actuated by the improved motor may be of any desired construction; but for'thepurposeof illustration the drawings represent a double-acting pump A.

bc'rs' F and- F through which the motor agent enters; of outlet-chambers F and F through which the motive agent exhausts and escapes through the discharge-pipesF and F and of cylindrical valve-seats F and F surrounded by said chambers and provided, respectively, with a circular series of inletports opposite the inlet-chambers and opening into the same, and a circular series of outlet-ports opposite the outlet chamber and opening into the same, as hereinafter more fully described.

In the chests F and F are fitted to slide longitudinally the cylindrical valves G and G, respectively, the rims of which are:adapted to open and close the inlet-portsand the outlet-ports alternately, as will be readily understood by reference to the drawings. The

cylindrical valves G and G are formed with a central hub and radial spokes, so as to make a discharge-opening for the cylinders E and .E at the time said valves are seated over the inlet-ports of the inlet-chambers F and F respectively, and said valves being at all times either entirely surrounded or entirely filled with the motive agent and having outlet-ports or inlet-ports entirely around their Iperimeters at all times are constantly and perfectly balanced. It is understood that the .chests Fand F are somewhat larger in diameter than thevalve-seats F and F so that the incoming motive agent can circulate all around the chest and pass intothe cylinder from all sides at the time the valve is in an outermost position in the respective chest.

The valves G and G are provided with outwardly-extending valve-stems H and H, respectively, passing through suitable stuffingboxes in the heads attached to the chambers F and F stems H and H are pivotally connected with transversely-extending arms I and I, respectively, pivoted at their rear ends to brackets The outer ends of the valveattached to the heads ofthe chambers F and F pivotally connected with each other by a rod J, as plainly illustrated in Fig. 2, the said rod sliding in bearings K and K formed on the arms of K and K, respectively, securedto the power-rod G at opposite sides of the pump A, The bearings K and *K of the arms K and K, respectively, are adapted to engage col- .lars L and L respectively, formed on the ends of the springs L and L, respectively, preferably made V-shaped, asshown in Fig.

The free ends of the arms I and I are 2, and carrying on their outer ends collars L and L fitted to slide looselyon the rod J. It is understood that the collars L and L are also fitted to slide loosely on the rod J. The collars L and L are adapted to abut against collars N and N, respectively, secured by set-screws or other means to the rod J. The collars N and N are adapted to abut against shoulders O and 0 respectively, of springarms 0 add 0, respectively, secured to the chests F and F, respectively, as plainly shown in Fig. 2. The spring-arms O and 0 have their free ends 0 and O curved to be readily engaged by lugs P and P, respectively, secured to the arms K and K, respectively, above described.

The operation is as follows: When the several parts are in the position as illustrated in the drawings, then the valve G is seated over and closes theinlet ports of the chest F, while the outlet-ports of said chestF are left open to exhaust the cylinder E. Mean while the valve G is seated over and closes the outlet-ports of the chest F, while the inlet-ports of said chest F are left open, sothat the motive agent can pass through the chamber F into the cylinder E, forcing the piston D in the direction of the arrow 0., and thereby moving the power-rod O, the piston B, and the piston D in the same direction, as will be readily understood by reference to Fig. 3. The movement of the power-rod G to the left, as described, causes the arm K to engage the collar L of the spring L, the other end of which abuts with its collar L onto the collar N of the rod J 5 but as the said collar N abuts against the shoulder O of the spring-arm O the rod J is held in a locked position and the spring L is compressed on the further motion of the arm K to the left. WVhen the piston D is near the end of its stroke outwardly, then the lug P on the arm K comes in contact with the curved end 0 of the spring-arm 0, so as to move the said spring-arm rearwardly, disconnecting the shoulder 0 from the collar N, whereby the spring L is released, and the latter exerts its pressure on the said collar N and forces the rod J to the left. By doing so the positions of the valves G and G are changed as the rod Iis swung outwardly and carries the valve G from the chamber F into the chamber F while the arm I is swung inwardly and moves the valve G from the chamber F into the chamber F By this move ment the inflow of the motive agent is cut off from the cylinder E, while the motive agent entering the chamber F can flow into the cylinder E, the outlet of the latter being closed by the valve G being seated in the chamber F over the outlet-pipe F The motive agent flowing into the cylinder E now exerts its pressure against the piston D, forcing the latter in the inverse direction of the arrow a, thus carrying the power-rod O, the piston B, and the piston D in the same direction, the motive agent in the cylinder E being discharged through the valve G into the chamber F and from the latter (passes) to the outlet F". When the rod J was shifted to the left, as previously explained, the collar N was passed beyond the shoulder 0 of the spring-arm 0 toward the collar L Now when the powerrod 0 moves in the inverse direction of the arrow a the arm K compresses the spring L and finally releases the same at the time the lug P engages the end 0 and moves the spring-arm O rearwardly to disengage the lug 0 from the collar N. This takes place at the time the piston D is at or near the end of its outward stroke. As soon as the spring L is released it forces the rod J to the right, thus changing the relative positions of the valves G and G, moving the same back into.

the original position shown in Figs. 2 and 3. The above-described operation is then repeated.

It will be seen that this motor is very simple and durable in construction, is completely automatic in operation, and develops considerable power, it being understood that the stroke of the piston B is equal to that of each of the pistons D and D. It will further be seen that the motor is notliable to get out of order, and as the most of the parts are located on the outside of the cylinders and chests they can be readily examined and inspected at all times to insure their proper workings.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1.
