ANATOLE EXUPERE BOUIF, OF MONTREAL, QUEBEC, CANADA.

MOTOR.

SPECIFICATION forming part of Letters Patent No. 264,767, dated September 19, 1882.

Application filed April 17, 1882. (No model.)

To all whom it may concern:

Be it known that I, ANATOLE EXUPERE ROUIF, of the city of Montreal, in the district of Montreal, and Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improvementsin Motors; and I do hereby declare that the follon'iugis a full, clear, and exact description of the same.

The invention has reference to improvements in that class of motors in which a coiled spring is used as the initiatory power, and is particularly applicable to sewing-machines and other light machinery of-a similar class. It may be briefly described as consisting of a coiled spring arranged in connection with a train of gears and a crank to give rotary motion to a driving-wheel, 850., in either direction, and so adapted as to allow the operator to reverse the direction of revolution at will while using the same coiled spring. Certain devices for reversing, breaking, and stopping the mechanism are also included in my invention. To thoroughly comprehend the same reference must be had to the accompanying drawings, in which similar letters of reference indicate like parts, and where- Figure l is a side elevation of part of a sewing-machine,showing my mechanism arranged to operate same, the case surrounding same being in section. Fig. 2 is a back elevation of same; Fig. 3, a detail showing adjustment for difl'erent sizes of machines; Fig. 4, a view of main driving-gear and operating-spring, and Fig. 5 a detail of device for reversing action of same.

A represents the table of the machine; B, its driving-wheel; C, the main driving-wheel actuating the wheel B through a strap, 0,

and journaled in the frame-work A, all constructed and arranged in any ordinary or approved manner. When my motoris attached to a sewing-machine the existing drivingwheels, 850., will be used.

Underneath the'table A, I attach a box or casing, D, of suitable size, configuration, and strength to contain a train of gears, E E, the shafts E E F F of which are journaled in said casing. Upon the upper one of these shafts, F, is mounted rigidly a gear-wheel, G, (shown in Fig. 1,) and on the same shaft, but loosely, the main driving-gear H is mounted.

Cast in one with this gear H is a cylindrical easing, h,insidewhieh is coiled a strong spring, I, secured at its outer end, i, to the casing IL and at its inner end, i, to the shaft F. This coiled spring is wound up by a lever or key operating on the shaft F in any approved manner.

A ratchet, K, is firmly mounted on the shaft F, close to the casing h, and is provided with a pawl, k, pivoted to said casing. This is for the purpose of preventing the shaft F from turning backward as the spring is wound up, and the pawl k is drawn in and outofgear with the ratchet by means of a hand-lever, Ir, projecting through the casing 1), when it is desired to reverse the action ofthe motor, as will be hereinafter described.

On the shaft F, or that which carries the lowest gear-wheel, l mount a friction-wheel, L. This friction-wheel is preferably covered withrubber, and has pressed against it by a spring, I, a regulating-brake, M, pivoted to the casing D at m. By depressing a treadle, N, connected to the brake by a system of suitable levers, n, the brake M is thrown off from the friction-wheel L, or its pressure thereon lessened or regulated, at will.

One end of the shaft F projects somewhat beyond the casing D, and is connected by links 0 Oto the main driving-wheel C at 0, and in this manner gives rotary motion to the same, which in turn drives the machine. Thelinks O O are slotted, as shown at p 1), so that one set may be adjusted to fit different sizes of machines.

Q is a sliding stop, which I throw between the teeth of the main driving-gear H when I wish to prevent the coiled spring I from operating or the gears from revolving. The regulatingbrake M may be found sufficient for this purpose; but I prefer to use also the stop just described.

The mechanism thus far described, omitting the gear G, will operate the ordinary class of sewing-machine and other machines which do not require to have their action reversed, and by winding up the spring I on the shaft F, in a manner somewhat similar to a watch, at stated intervals, the motor will operate by the outer end, i, of the said spring pressing on the casing IL, and thus rotating the driving-gear H and train of gears, the foot of the operator 4 it is desired to rotate the gears and drivingwheels in the opposite or reverse direction, I first release the pawl 7c from the ratchet K by pulling out the lever 70, and then shift the shaft F to the right orleft, as the case may be, by means of the lever P, which is connected to the shaft F, as shown in Figs. 1 and 5. (The said shaft slides easily in its bearings in the casing D.) The gear H isthus thrown out of gear with the gear 6 on the shaft below, and the gear G comes into gear therewith, and the pawl 70 no longer offering resistance to the ratchet K, the shaft F, and with it the gear G, mounted firmly thereon, commences to revolve in the reverse direction and communicates inolion in the same way to the train of gears, driving-wheels, &c. This is effected by the inner end, t", of the spring I, working (in place of the outer end, '2', as described in the first operation) against the'sh'aft F, and thus rotating same, the pawl 7c of course being again thrown into the ratchet K to prevent the gear H and easing h from rotating except with the shaft, it being understood that in this case the outer end, 2', of the coiled spring I will be held and prevented from working, so that the whole force of said spring may be used at the opposite end in rotating the shaft F.

The operation of my invention will be so clearly understood from the foregoing as to require no explanation further than to say that to start the machine the stop Q, is released from the gear H and the spring I wound up by turning the shaft F by a key, &c., after which the foot of the operator is placed on the treadle N, which releases the brake M from strong contact with the friction-wheel L, and the working then proceeds. operator takes his foot off the treadle and the brake holds the friction-wheel steady. The lever P is then drawn to one side, as explained, and the gear Gr thrown into gear with the gear 2, and the pawl it again caused to interinesh with the ratchet K.

What 1 claim, and desire to secure by Letters Patent, is as follows:

The means herein described, for reversing the action of acoiled motor-spring by causing either end of such spring to work While the other is held fast, consisting in a fixed gearwheel mounted on a shaft, and a loose gearwheel revolving on said shaft, the coiled spring being attached at its outer end to a projection or casing formed in one with such loose-gear, and theinner end of said spring being secured to said shaft, which is moved in the direction ofits axis to cause either gear at will to intermesh with the first of a train of gears, substantially as set forth.
