SPECIFICATION forming part of Letters Patent No. 540,227, dated June 4, 1895.

Application filed October 15,1894- Serial No. 526,008. (No model.)

specification.

This invention relates to power-motors employing a coiled spring to produce the power, and from which spring the power is transmitted through a train of gears to the work being done, which in this case is pumping.

The object of the invention is to construct a practical machine in which the power is more effectually controlled, and in which are employed improved means for winding the spring, making it comparatively easy, and means for stopping and starting said machine, the design being that such machines will largely supplant the use of wind-mills in pumping water.

In the drawings forming a part of this specification, Figure l is a plan view of Figs. 2 and 3; Fig. 2, a side elevation of one side of Fig. 1, with parts in section on dotted line 2 2 in Fig. 1; Fig. 3, an elevation of the other side of Fig. 1; Fig. 4, a vertical section of the pump in Fig. 2 on dotted line 3 3; and Fig. 5 shows enlarged details from Figs. 1 and 3, below described.

Referring to the lettered parts of the drawings, A is a frame-work for supporting the parts of the machine. A spring-case is shown at B, containing a coiled spring 0, which spring is attached to the shaft D. On the shaft D, is a gear E, which gear meshes with the gear F, of a shaft G. The shaft G, is also provided with a gear H, which gear meshes with a gear I, on the shaft J. This shaft J, is provided with a gear K, which gear meshes with a gear L, on the shaft M. This shaft M,

terminates at oneend in a crank N.

At 0, is a connecting-rod pivotally connected at one end to the crank N, and pivotally connected at the other end to one end of the walking-beam P, and to the other end of said walking-beam P, ispivotally connected the pump-plunger Q, of thepump B. By this means of gears and shafts the power of the spring 0, is transmitted to the pump R, but

any suitable modifications or changes may be made in the train of gear desirable, the one shown illustrating the idea. I

A suitable pump having ball-valves, simple in construction for use with spring power, is shown at R, in Fig. 4.

Revolving sails are shown at S, forming a power controlling brake similar to that employed in a clock, and may be used for the same purpose in this power. The sails S, are revolved by means of gears T, U, V, and W, the gear T, receiving its motion from the revolving shaft M, upon which it is mounted.

At X, is a lever which is brought into contact. with the sails S, to stop the machine, and is held by apin Y, or other means may be employed. On the shaft G, are two cam-disks Z, provided with lateral cam-projections 6, the cam-projections of one disk alternating in their position on the disks with those of the other disk Z.

At 7, 7, are two controlling-brakes,consisting of weighted levers which rest on thecamprojections 6, of the cam-disks Z, the inner ends of said weighted levers 7, 7, being pivoted to the frame-support A, at 8, 8. It will be observed that that portion of the levers which rests on the pins 6, is V-shaped. This gives a longer distance of contact of said pins with the levers in proportion to the length of the levers 7, and one pin climbs as it werethe incline of onelever 7, while in its 'npward movement, and another pin descends the incline of the other lever during its downward movement. Thus one pin is always climbing an incline. By this a greater movement up and down of the leversis secured as well as a slower one; but while this construction is preferable it is not always necessary. During the operation, one of these weighted levers will rise when the other lowers, alternating with each other in these movements, and thus keep a constant brake engagement with the cam-projections 6, of the disks Z, and thus keep the power of the spring 0, under control.

In weighted governor arms having a frictional engagement with the periphery of a crank-disk heretofore employed, there is a constant dead frictional wear on the lever at one point, and it is the resistance of the friction alone which resists the power, and frequently greatly detracts from the desired cfnitely being lifted, and the point of frictional engagement of the cam-pins on the levers or arms is constantly changing, and does not become a dead resistance against the effect of the power, for it is the constant lifting of the weighted arms that gov erns,and notaltogeiher the friction of the cam-pins. Besides in order to have the effect on the machine as of a con-- stant lifting of a weight, there must be two disks, the position of the cam-pins of which alternate with each other, and two weighted arms, so that one will lower while the other rises as stated. These controlling-brakes may be employed in lieu of the revolving sails S, or vice versa, or both may be used at the same time if found desirable.

A support 10, has a sliding connection with the frame support A, Fig. 3. In the top of this support 10, is a gear 11, and ratchet 12. When the support with its gear and ratchet are raised, the gear 11, meshes with the gear 14, attached to the shaft G, and the gear 11, is held to this engagement by the slidingcatch 13, which holds up the support 10. By means of a paw1-lever'15, Figs. 3 and 5, which is attached to the axle of the gear 11, and'ratchet 12, the spring 0, is wound up by oscillating said pawl-lever. After said spring is Wound the latch 13, is released and the support 10 with its gear and ratchet are again lowered, disengaging said gear from the gear 14.

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

1. A power motor, comprising a supportingframe, a pump, a power-spring, a suitable train of gears transmitting the power of the spring to the pump, the camdisks in said train of gears provided with the cam-projections alternating with each other on their disks, and the controlling-brakes consisting of the weighted levers contacting with said cam-projections, and alternating with each other in their up and down movements, substantially as set forth.

In testimony of the foregoing I have hereunto set my hand in the presence of two witnesses.
