SAMUEL N. SILVER, OF AUBURN, MAINE.

MOTOR.

SPECIFICATION forming part of Letters Patent No. 254,712, dated March '7', 1882..

Application filed January 21, 1882. (Model) -Be it known'that I, SAMUEL Ns'SILVER, of

7 Auburn, in the county of Androscoggin and State of Maine, have invented a new and ImprovedMotor, of which the following is a full,

clear, and exact description.

The object of my invention is to provide a new and improved motor or device for applying power in, a'very effectual and economical man ner.

The invention consists of one or more sliding and reciprocating cylinders, containing pistons held in these cylinders by latches, which pistons are each adapted to slide one. central rodsurrounded by a coil-spring, to which pistons rocking arms are pivoted, which are loosely mounted on a shaft, these arms being provided with pawls 'or other suitable clutchingdevices for rotating the shaft. When the cylinders are pressed downward the springs are brought in tension, and when the springs exert the power a stored in them they rotate the shaft, as will be fully described hereinafter.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate-corresponding parts in all the figures.

Figure lisa frontlongitudinal sectional elevation of my improved motor on the line :20 a, Fig. 3. Fig. 2 is a side longitudinal elevation of the same. Fig. 3 is a sectional plan view of the same on the line 1} y, Fig. 1.

The shaft Ais journaled in a suitable frame, B, and has afly-wheel, O, and a pulley, D, rigidly mounted on the ends; or in place of the fly-wheel and pulley any other wheels or cranks can be mounted on this shaft. The shaftA is also journaled in the shanks E of a frame, which shanks each have arectan gular bend, E, at that part at which the shaft is journaled, and from this bend the shanks extend downward as rods E At each side of each shank E an arm, F, is loosely mounted on the shaft,

a pawl, G, and the other with-a friction-clutch pawl, H, and the corresponding ratchet and friction wheels, G and H, must be mounted on theshaft A, adjoining the arms F F, as shown. Those ends of the arm F opposite the ones'to I which the pawls are pivoted are each provided i in the end with a longitudinal recess or slot,"a, through which a screw or pintle, J ,"passes into a cylindrical piston, K, provided with a longitudinalslot, K, extending from the top almost to the bottom, which pistonis loosely mounted springs N, attached to the cylinders L, through i slots N in these cylinders into notches O in the-pistons K, whereby when the cylinders L are moved downward the pistonsK will move downward with them. The cylinders L are drawn upward or toward the shaft A by springs P, attached to the bends E, and to the lower ends of the cylinders L. The pistons K are forced in the same direction as the cylinders L by springs Q, coiled around the rodsE and resting against thelower end of t-hepistons K, and against cylindrical sockets R, screwed on the lower ends of the rods E and fitting within the lower ends of the cylinders L. The lower ends of the cylinders L are surrounded by cylindrical guide-frames S, also attached to the. lower ends of the rods E between which sockets R and cylindrical frames S the lower ends of the cylinders L are guided. The cylinders L are provided with longitudinal slots K for the passage of the bends E The operation is as'follows: If a downward pressure is exerted on the cylinders L, they will move downward, and their latches M M will draw the pistons K downward with these cylinders, and these pistons draw downward the outer ends of the arms F, thereby raising the inner ends of the same, and causing the pawls G or H to slide over the edges of their corresponding wheels, G or H. By this downward movement of the cylinders L the springs P are stretched, and the springs Q are compressed. As soon as the pressure is removed from the cylinders L the springs P and Q will force the cylinders L and the pistons K upward, causing the pawls G or H to catch on the wheels G or H, and to rotate the shaft A in the direction of the arrow a. Then the cylinders are again depressed and released, to be drawn upward by the springs, and so on. Both cylinders L can be depressed together; or they can be operated alternately, so as to obtain a continuous rotation of the shaft. The cylinders can be operated by hand or footpower, by animals, water-power, or steam, gas, or air engines. The power is stored and accumulated in the springs, and they furnish the power as it is required. A very great amount of power is economized, as I will now show. For instance, if my motor is operated by a steam-engine, and if at any time there is very little resistance offered to the shaft,1simpl y decrease the number of strokes of the engine, thereby increasing the time required to depress the cylinders, but not affecting the rapidity of the rotation of the shaft, but decreasing its power. I gain very much in power by this manner of operating,forby reducingthenumberofstrokes of the engine the friction is avoided to a very great extent, and consequently the power required to overcome the friction is economized.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent-- the shaft, and of the reciprocating cylinders provided with springs for forcing the cylinders upward, substantially as herein shown and described, and for the purpose set forth.

3. In a motor,the combination, with the shaft A, of the rocking arms F, provided with devices for acting on the shaft, the reciprocating cylinders L, containing pistons K, connected with the ends of the arms J, and of the springs.

P, substantially as herein shown and described, and for the purpose set forth.

4. In a motor, the combination, with the shaft A, of the rocking arms F, provided with devices for acting on the shaft, the reciprocating cylinders L, containing the pistons K, each provided wlth a longitudinal slot K and sliding on the rods E and of the springs Q, substantially as herein shown and described,and for the purpose set forth.

5. In a motor, the combination, with the shaft A, of the rocking arms F, provided with devices for acting on the shaft A, the cylinders L, the pistons K, the rods E the springs Q, and the latches M, substantially as herein shown and described, and for the purpose set forth.

6. In a motor, the combination, with the shaft A, of the rocking arms F, provided with devices for acting on the shaft A, the cylinders L, the pistons K, the rods E the springs Q, the clutches M, and the springs N, substantially as herein shown and described, and for the purpose set forth.

7. In amotor, the combination, with thesha-ft A, of the rocking arms F, provided with devices for acting on the shaft A, the cylinders L, the pistons K, the rods E the springs Q, the cylindrical sockets R, and the guide-frames S, substantially as herein shown and described, and for the purpose set forth.
