SPRING-MOTOR.

SPECIFICATION forming; part of Letters Patent No. 396,243, dated January 15, 1889.

Application filed Jul 31,1888. Serial No. 281,514. (No model.)

T0 to whom it may concern:

Be it known that I, CHARLES H. SMITH, a citizen of the United States, residing at Beaumont, in the county of Butler and State of Kansas, have invented a new and useful Improvement in Spring-Motors, of which the following is a specification.

My invention relates to an improvement in spring-motors adapted for running street-railway cars, pumps, elevators, and other machinery; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claim.

In the accompanying drawings, Figure l is a top plan view of a spring-motor embodying my improvements. Fig. 2 is a vertical longitudinal sectional view of the same, taken on the line a; a of Fig. 1.

A represents a rectangular frame, which comprises a pair of longitudinal beams, B, and a pair of transverse beams, C, which connect the same at their ends.

D represents a driving-shaft, which is journaled in bearings E in the beams B, ata suitable distance from one end of the frame. On the center of this shaft is loosely secured a spur-wheel, F.

G represents a pair of ratchet-wheels, which are keyed to the shaft and arranged 011 opposite sides of the wheel F. Pivoted to the latter are spring-actuated pawls II, which engage the ratchet-wheels G, and thereby permit the shaft to rotate in one direction without turning the wheel F. To one end of the shaft E is secured a crank-arm, I.

K represents a pair of volute springs, which have their inner ends attached to the shaft 1), and have their outer ends secured to a bolt rod, 1 which extends transversely to the frame.

M represents a shaft, which is journaled in bearing-boxes upon the sides of the frame, and is arranged parallel with the shaft D and at a suitable distance therefrom. To one end of the shaft M, which projects beyond one proved motor. is keyed a pinion, P, which meshes with the wheel F.

R represents a shaft, which is parallel to the shaft M, and is journaled in bearings in one end of the frame. To this shaft R is keyed a pinion, S, which engages a spur-wheel, T, that is secured to the shaft H, and thereby the rotary motion of the latter is imparted to the shaft B. To one end of the shaftR is socured a crank-disk, U, provided with awristpin, V, by means of which a suitable pitman (not shown) may be attached to the crankwheel to impart reciprocating motion to the plunger of a pump or churn, which it may be desired to operate by my improved motor.

It will be understood from the foregoing that when the shaft 1) is turned by the crank I in the direction opposite that indicated by the arrow in Fig. 2 the wheel F remains idle,

the pawls slip over the teeth of the ratchet-.

wheels, and the springs are wound. The springs in uncoiling cause the shaft D and the wheel F to revolve in the direction indicated by the arrow in Fig. 2, and, by reason of the gears hereinbefore described, impart accelerated rotary motion to the shafts M and R.

V represents a vertical shaft, which has its lower end stepped in a box or block, X, on the frame directly above one of the bearings of the shaft M, and the upper end of the said shaft \V is journaled in a bearing at the upper end of a curved arm, Y, which. is secured on the frame.

Z represents a beveled pinion, which is keyed to the shaft \V, and engages the wheel N, and consequently causes the rotary motion of the shaft M to be imparted to the shaft \V. A yoke, A, is secured to the said shaft XV at a suit-able height, and at a suitable distance be low said yoke is a plate or disk, 13, which has a central opening, through which the shaft \V extends, and is adapted to move vertically on the said shaft.

0 represents a pair of governor-arms, which are fulcrumed near their centers to the ends of the yoke A, and have weight-balls 1) secured to their lower ends. The upper ends of the governor-arms are connected to the plate B by means of link-rods E.

The rotary motion of the shaft XV causes To the center of the shaft M the weight-balls to whirl, and as said shaft is running at high speed the weight-balls rise by centrifugal force and the links connected to the goVernor-arms cause the disk or plate 3 to descend. lVhen the speed of the shaft \V decreases, the weight-balls become lowered by gravity, and consequently cause the plate or disk 13 to rise.

F represents a plate or arm, which projects from the frame and has an opening in which the shaft rotates. A coiled exteusile spring, G,is placed, on the shaft \V and bears against plate F and the disk )1. \Vhen the plate or disk .3 descends when the shaft \V is in rapid rotation, the spring is compressed and caused to exert so much friction against the plate 11" and disk 4; as to cause the motor to run at a slower rate of speed. \Vhen the speed of the motor is lowered, the disk 3 rises, and thereby reduces the frictional resistance of the sprin and by this means the governor serves to regulate the speed of the machine.

Having thus described my invention, 1 claim The combination of the frame, the shaft M, journaled therein, the gear-wheel N on the end of said shaft, the spring-actuated drivingwheel geared to said shaft M, the vertical. shaft V, arranged at one side of the frame, the pinion on said shaft meshing with the wheel N, the curved arm Y, erected on the frame and receiving the upper end of the shaft V, the arm F, projecting from the frame, the disk B, movable on the shaft \V, the spring around said shaft between the arm F and the disk B, the yoke A, the governor-arms pivoted in the ends of the yoke, and the links E connecting the governor-arms with the disk 13, as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

CHARLES H. SMITH.
