SPRING-MOTOR.

SPECIPTCATION forming part of Letters Patent No. 340,799, dated April 27, 1886.

Application filed October 9. 1885. Serial No. 179,436. (No model.)

This invention relates to that class of springmotors which are employed for operating sewing-machines, jewelers lathes, and similar light'running machines, and in which the.

'powcr is transmitted from a coiled spring through a train of gearing to the driving-shaft of the machine.

The object of my invention is to provide a 1 simple, compact, and noiseless motor of this character; and the invention consists of the improvements which will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, consisting of two sheets, Figure 1 is a sectional elevation of my improved motor. Fig. 2 is a horizontal section in line m a, Fig. 1. Fig. 3 is a longitudinal sectional elevation in line y y, Fig- 1. Fig. 4 is a detached side elevation of the springbarrel and alarm device. Fig. 5 is a fragmentary sectional elevation of the brake. Fig. 6 is a cross-section in line w 00, Fig. 5. Fig. 7 is a cross-section in line 2 .2, Fig.

Like letters of reference refer to like parts in the several figures.

A represents the table, and A a portion of the frame of a sewing-machine supported thereon.

a represents the driv i ng-shaft of the machine,

5 supported in hearings in the frame A, and provided with the usual driving pulley, a, and fly-wheel a. t

B B 13* represent the hangers or frames of the motor, which are secured to the under side .0 of the table A and connected at their lower ends by brace-rods b.

0 represents a horizontal shaft journaled in bearings in the frames B B", and O represents a drum or barrel, which is mounted 5 loosely on the shaft C and incloses a coiled spring, D. The barrel 0 is preferably cast in two parts, 0 c, which are secured together by screws or bolts 0", inserted through lugs 0, formed on the adjacent sides of the parts 0 c.

The outer end of the spring D is secured to the barrel 0 by a nut, d, and its opposite end E and gear-wheel E are turned to wind the springD upon the shaft G. The wheel E is held from turning backwardly by the worm E.

F represents a toothed wheel mounted on an arbor, f, secured to one side of the barrel C, and f is a tooth or projection formed on -or secured to the shaft 0, and engaging .be-

tween the teeth on the wheel F in such manner that the wheel F is moved the distance of one tooth at every revolution of the shaft 0. 7::

G represents an alarm bell secured to the side of the barrel 0, and g is a spring-haui- Iner, which is adapted to come in contact with a pin or stop, g, on the wheel F as the latter revolves. The stop 5/ is so arranged on the wheel F as to cause the hammerg to strike the bell and sound an alarm when the spring D has been sufficiently wound.

H represents a gear-wheel, which is secured to the opposite side of the springbarrel C by screws 11, so as to revolve with the barrel.

2 i '1' represent short shafts or spindles j ournaled in hearings in the frames B B".

I I 1* represent gear-wheels, and J J J are spur pinions secured, respectively, to the 8 shafts ii The gear wheel H, secured to the spring-barrel O, meshes with the pinion J on the shaft i, and the gear-wheel I on the shaft 2' with the pinion J on the shaft i, and the gear-wheel 1 on the shaft t" with the pin- 3 ion J on the shaft 1'5", whereby lnotionis transmitted from the springbarrel O to the shaft z through the gearwheel H and pinion J, and from the shaft to the shaft i through the gear-wheel I and pinion J, and from the shaft t" to the shaft 6' by means of the gear-wheel I and pinion J K is a countershaft journalcd in bearings formed in the hanging f ramcs I B 13* and provided with apinion, it, which meshes with the gear-wheel I on the shaft i whereby motion is transmitted from the shaft i to the shaft K.

' motion of the machine is arrested.

The shaft K is provided with a belt-pulley, L, which is connected with the driving-pulley a of the sewing-machine by abelt, Z. Motion is in this manner transmitted from the spring D through the train of gearing to the drivingshaft of the sewing-machine.

M represents a brake-pulley secured to the shaft K so as to turn therewith.

' N represents the brake rod, which is provided at its lower end with a horizontal pressure-finger, n, which is adapted to bear against the brake-pulley M and stop the motion of the machine. The brake-rod N is guided near its lower end by a pin or screw, 0, secured to the frame B and passing through a slot, 0, formed in the brakerod. The upper end of the rod N extends through an openingin the table A, and is pivoted to the short arm 1) of a handlever, P, which latter is pivoted to a vertical post, q, secured to the top of the table A.

r is a fiat or othersuitable spring secured to the frame B and bearing against the brakerod N, whereby the pressure-fingern is forced against the brake-wheel. Upon pressing down upon the long arm 1) of the hand-lever P the rod N is raised until the horizontal portion a of the finger n is forced against the inner face of the rim of the brake wheel, whereby the \Vhen the brake is thus applied, the spring-barrel O is held from turning through the gear-wheel H and train of gearing communicating with the shaft of the brake-wheel.

When it is desired to wind up the spring I), the brake is applied and the shaft 0 revolved, by means of the hand-crank e and wornrgear E E, until the stop 9 comes in contact with the hammer and causes the latter to strike the bell and sound the alarm, when the oper ator is informed that the spring has been wound sufficiently tight. The arm 3) of the hand-lever is now raised, so as to release the brake, when the pressure of the spring D upon the barrel (1" will cause the latter to revolve and set the train of gearing in motion. gear E E.

If desired, the spring may be wound upon the shaft 0 while the machine is in motion by turning the handcrank 6 The wornrwheel may be made right or left handed,to suit the different styles of machines to which the motor is applied.

\Vhen it is desired to regulate the speed of the machine, the brake-rod N is raised sufficiently to permit the spring 1- to press the side The shaft 0 is held at rest by the wormof the finger against the face of the brake Wheel without touching the rim of the wheel.

My improved motor is simple in construction and is entirely noiseless, and can be readily applied to any sewing machine or other light running machines where light power is required.

I claim as my invention-- 1.- In a spring-motor, the combination,with the shaft 0, and the drum G,mounted loosely on said shaft, of a spring.
