SPR|NG-MO'TOR.

SPECEFICATION forming part of Letters Patent No. 307,309, dated October 28, 1884.

Application filed May 3,1884. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES L. KIDDER, a citizen of the United States, residing at New Brunswick, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in Spring-Motors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

Figure 1 is a front view of the entire machine; Fig. 2, an end view of the left-hand'cnd of machine; Fig. 3, a top view of bearing-frame 1 removed from the machine and supporting the winding-cylinder,winding-shaft,bevel-wheels, and stop-work mechanism. Fig. 4 is an enlarged view of friction device used when winding by the foot of the operator; Fig. 5, a sectional view of the same; Fig. 6, an enlarged view of center of wheel 0, with the frictionpawl, the hub in which the pawl is held, and the manner of fastening the same to the shaft. Fig. ,7 is an enlarged view of the mechanism by which I increase or diminish the tension of the spring.

The legs or standards A A, with the table B, constitute the frame of the machine. the frame is fixed the bearing-frame shown in Fig. 3, upon which are supported the winding-shafts a and b. Through the frame below the bearingframe passes the shaft d. On the frame, as shown in Fig. 2, is hung the pendent lever G, with a foot-rest at its lower end and having attached to it two connection-bars, I and H.

The bar I, in connection with the pendent lever and the mechanism shown in Fig. 4, pro vides an easy and noiseless method of winding by the foot of the operator or of renewing at intervals the power already expended in running the machine, and the bar H, when connected with the crank 6, providing a simple means of running the machine by foot-power when by reason of breakage of the motor or for any other reason it is not desired to use the motive power of the spring.

The motive power of the machine is a coilspring, D, contained within the fusee w, and 50 having oneend attached to the inside of the fusee, while the other is solidly connected with the shaft (Z. This shaft (1 is kept in position by the device shown in Fig. 7, by means of which, also, the tension of the spring can be increased or diminished, as may be desired. Upon the fusee or drum is wound a small cord, which is fastened at its other end to the winding-cylinder E. Said cylinder E is actuated by means of its connection by frictionelutch u, (shown in Fig. 6,) to awinding-shaft adapted to be revolved by a crank fitted upon either end. The winding-cylinder can also be revolved by means of the foot winding apparatus shown in Fig. 3, and it is prevented from being wound too tightly by means of the safety 6 5 stop mechanism (shown in Fig. 8) r and p.

The principal features in this mechanism have already been patented to me. The novel features are the new method of winding by means of the foot-lever G and the connected parts.

The operation of renewing the power by the use of my improvement is as follows: The foot of the operator is placed upon the foot-rest g of the pendent lever G, and the pendent lever 7 5 is swung toward him. This motion brings the spring h to bear upon the pin 17, which is made fast in the friction-pawl j, thus making a connection between it and the inside periphery of the wheel F, which is made fast to the shaft I). The pendent lever G is now swung away from the operator, thus turning the wheel F, the shaft 1), the bevel-wheels 7. and Z, the winding-cylinder E, and by means of the cord winding the spring contained in the spring-box D. 8 5 Upon stopping the pressure of the'foot against the pendent lever G the small spring m (shown by dotted lines in Fig. 4) swings the frictionpawl forward and away from the inside periphery of the wheel F, leaving it free to turn 0 by the action of the driving spring. It is to be particularly noticed in this connection that, unlike friction-clutches now in use, my device turns the wheel F in one direction and then instantly allows it to turn back again in the op- 9 5 posite direction, whereas the common frictionclutch is adapted simply to turn a wheel continuously in one direction. This operation continued gradually rewinds the spring.

The second improvement consists of the crank a on the end of the driving-shaft 0, and the connection-bar H, attached to the pendent lever G, and adapted to connect the crank l l c with the pendent lever, and form a simple method of running the machine by foot-power, the spring being entirely disconnected. The length of the bar H is such as to prevent the bar I from coming back so far as tolorm a connection between the friction pawl j and the wheel F when the machine is being run by foot-power.

Having thus set forth my in vent-ion, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a spring-motor, friction-clutch having a lever impinging against the periphery of the wheel to be revolved and adapted to give such wheel a forward movement when desired and to permitits backward movement as soon as the forward movement of the clutch and wheel have ceased, substantially as de scribed.

2. In a spring-motor, a shal't connecting the driving-wheel with the mechanism operated by the 1notive-s )ring thereof so as to cause such wheel to be driven thereby, and also adapt ed to communicate motion to the driving-wheel from a power independent of the springpower of the mechanism, substantially as described.

3. In a spring-motor, the combination, with the pendent lover, of a winding apparatus adapted to be operated by meansof a frictionclutch, substantially as set forth.

4. In a spring-motor, the combination of a l connecting-shal't having at one end a drivingwheel, devices constituting suitable means of connection to the motive power of the mechanism, a pendent lever, and devices constituting suitable means 01 a connection between such lever and a shalt so arranged that motion may be imparted to the driving-wheel through such pendent lever inde iendcntly ol" the moti ve power ofthe mechanism, all substantially as described.

v 5. Ina spring-motor, ihe combination of a fusee containing a spring-box, a spring eonnccted at one end to sncn box and secured at the other to a shalt, a winding cord or belt, a windirig-cylinder, a friction-clutch adapted to actuate the winding-cylinder, and devices constituting the means for connecting such clutch with a pendent lever, whereby the whole cornbination can be operated, subslaniiially as set forth.

(S. In a spring-ureter, a connecling-shaithaving at one end a drivingavhecl, and adapted at the other end to receive motion from a vibrating pendent lever through proper devices constituting the means oi connection, a gear wheel adapted to revolve rid connecting shal't, a wimung-cylinder, windingshalt, a belt or cord, a 'l'usce or drum containing-a Spring-lam and spring connected thereto, all substantially as dcscri bed.
