ISAAO S. PATTON, OF KANSAS CITY, MISSOURI, ASSIGNOR OF ONE-HALF TO FREDERICK VAN SEGGERN, OF SAME PLACE.

SPRING-MOTOR.

SPECIFICATION forming part of Letters Patent No. 460,655, dated October 6, 1891.

Application filed March 20, 1891. Serial No. 385,774 (No model.)

To all whom it may concern:

Be it known that I, ISAAC S. PATTON, of Kansas City, Jackson county, Missouri, have invented certain new and useful Improve: ments in Spring-Motors, of which the following is afull, clear, and exact description, reference beinghad to the accompanying drawings, forming a part hereof.

My invention relates to spring-motors; and

the objects of my invention are, first, to prosists in certain peculiar and novel featuresof construction and arrangement, as hereinafter described and claimed.

In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which Figure 1 is a side elevation of myimproved spring-motor, a portion of the supporting frame-work being broken away. Fig. 2 is a front view of the same. Fig.3 is a view similar to Fig. 1, but with the near side of the framework entirely removed. Fig. 4 is a detached View of the regulator. Fig. 5 is a detached View of the stopping and starting mechanism.

In the said drawings, 1 designates the frame-work which supports the train or gearing of the motor, the said frame-work being in two parts, each of which is preferably of skeleton or open form and approximately of rectangular shape, and the said portions being connected together by cross-rods 2. In the lower part of the frame-work is mounted the winding-arbor 3, upon which the main spring 4 is wound. This arbor 3 also carries a gear-wheel 5, the teeth of which mesh with a gear-pinion 6 upon an arbor 7, located in the frame-work 1 above the arbor 3 just described. The arbor 7 also carries a gear-wheel 8, the teeth of which mesh with those of a gear-pinion 9 on an upper arbor 10. This arbor 10 also carries agear-wheel 11 and abrakewheel 12. The winding-arbor 3 also carries the usual ratchet-wheel 13,the teeth of which 5 5 are engaged by a pawl 14, carried by the gear- Wheel 5, and said pawl is held in engagement with the teeth of the ratchet-wheel 13 by a spring 15, also carried by the gear-wheel 5. This pawl-and-ratchet mechanism serves to prevent the wrongful unwinding of the main spring 4, and insures the expenditure of the power derived from the spring through the described train of gearing.

In the lower part of the frame-work l at a point opposite that at which the arbor 3 is mounted is an arbor 16, and this arbor carries a gear-wheel17, the teeth of which mesh with those of a gear-pinion (obscured from view) on the said arbor 3, the said arbor 16 being thus rotated by the arbor 3. The arbor 16 also carries a beveled gear-pinion 18, the teeth of which mesh with those of a similar beveled pinion 19 on the lower end of avertical shaft 20. The lower end of this shaft 20 is mounted in a bracket 21, projecting inwardly from one of the frames 1, and the upper end of said shaft is mounted in a cross-bar 22, connecting said frames 1. The upper end of the shaft 20 carries a worm 23, which meshes with a worm-wheel 24 on a screw-shaft 25. This shaft 25 works through a screw-threaded opening in the cross-bar 22,and its inner end impinges upon the outer side of a curved flat spring 26. The lower end of this spring 26 embraces a lug 27, projecting inwardly from that part of the frame 1 which carries the bracket 21 and which is located just above said bracket.

The upper end of the spring 26 is formed 0 or provided with a brake 28, which presses upon the periphery of the brake-wheel 12, above described. The resilience of the spring 26 tends to lift the brake 28 off the wheel 12, and the arrangement of the described gearing is such that when the motor is being wound up the screw-shaft 25 shall be turned in one direction by the revolution of the gearwheel17, produced by the winding revolution of the arbor 3 and its obscured gear-pinion, I00 and transmitted by the beveled gears 18 and 19, shaft 20, worm 23, and worm-wheel 24, so

as to advance toward the spring 26 to press strongly upon the brake-wheel 12. t On the other hand, as the motor runs the screw-shaft is turned in the reverse direction by reversed movements of the parts just enumerated, and thus retracted from the spring, gradually relaxing the pressure of the brake 23 upon the brake-wheel 12 as the power of the spring at decreases by unwinding. It will thus be seen that the resistance upon the train of gearing of the motor gradually decreases as the power of the main spring decreases by unwinding, and that consequently the motor is caused to run evenly and to develop a uniform amount of power so long as itis in action.

In order to nicely adjust the resistance of the brake to the power of the spring 4, I provide the outer end of the screw-shaft 25 with a thumb-piece 29, so that the said screw-shaft can be turned by hand, and its initial pressure upon the spring 20 can be varied as desired.

In order to readily stop and start the motor,

I provide a second brake 30, which also presses upon the brake-wheel 12. This brake 30 is carried at the outer end of a spring-arm 31, which is attached to a rocking arbor 32, mounted in the upper part of the frame-work 1. From the said arbor 32 extends an arm 33, to the outer end of which is connected the upper end of a rod 34, the lower end of which carries a treadle, or in lieu thereof a handle, if preferred. The pressure exerted by the brake 30 upon the brakeavheel 12 is suflicient to overcome the power of the spring 4, and consequently when the brake 30 is in contact with the wheel 12 the motor does not run. By pressing upon the treadle 35 or pulling downward upon the rod 34: the brake 30 is lifted off the wheel 12, and the motor is free to run.

The motor is geared to the machinery which it is to run through an arbor 36, one end of which carries a crown-gear 37, which meshes with the gear-wheel 11, and the opposite end of which carries a belt-pulley 3S; and the motoris intended to run such machines as sewinganaehines, churns, jewelers lathes, doc.

It will be seen from the above description that the motor is simple, compact, and inexpensive of construction, and that its opera tion is uniform from first to last, while the amount of power developed is even or uniform as long as the motor continues to run.

Havingthus described my invention, whatI claim as new therein, and desire to secure by Letters Patent, is

1. An improved spring-motor comprisinga train of gearing and actuating-spring therefor, a brake-wheel carried by said train, a brake carried by a spring and operating upon said brake-wheel, a serew-shaft impinging upon said spring and carrying a worm-wheel, and a worm-shaft actuated by gearing operated by the train-gear and serving to diminish the pressure of the worm-shaft upon the brakespring in accordance with the diminution of power of themain spring, substantially as set forth.

2. An improved spring-motor comprisinga spring-plate carrying a brake at one end, a screw-shaft impinging at one end on said spring-plate, a worm-wheel carried by said screw-shaft, a worm -shaft engaging said worm-wheel and carrying a beveled gearpinion, an arbor carrying a gear-wheel meshing with the motor-train, and a beveled gearpinion meshing with the gear-pinion of the worm-shaft, substantially as set forth.

An improved spring-motor eomprisinga train of gearing, a motor-spring therefor, a brake-wheel carried by said train, an arbor carrying an arm, a brake carried by said arm and operating by contact with the brakewheel to stop the machine, a second arm carried by said arbor, and a rod attached to said arm and serving to rock the arbor for lifting the brake out of contact with the brakewheel when the motor is to operate, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

ISAAC S. PATTON.
