I IMPROVEMENT INISPRING1MOTORS.
Specification forming ,part of'Letters Patent No. 202,010, dated April 2, 1878 application filed To all whom it may concemr Y Be it known that we, FRANKD. EVERETT work, such as sewing-machines, clotheswringers, dental engines, &c. and it consists, primarily, of a fixed and stationary central shaft, to which is attached one end of a spring, said spring connecting said stationary shaft and the periphery of a drum or its equivalent; also, in producing motive power by attachin g one end of a spring to afixed stationary shaft or axle, and the other to the periphery of a drum or its equivalent, thus transmitting the entire power to the periphery instead of the axle, as has heretofore, as far as our knowledge extends, been done. It further consists in a suitable connection, by which the power of the spring can be applied through gearconnections to do light work, such as running sewing-machines, washing-machines, dental engines, scroll saws, &c.; also, in an improvedfriction-brake, whereby, through pedalpressure or any other means, the speed of the machine may be regulated and controlled by any given degree of braking employed.
In the drawings, Figures 1 and 2 are elevations of our device. Figs. 3 and 4 show the movable or adjustable feet, and the mannerof attachment. Fig. 5 shows, in detail, a longitudinal section of the driving-drum, its gear, and pawl -and-ratchet attachment, and the method of construction and operation of the driving-spring; Fig. 6, the winding device, and how it is thrown out of gear after performing its office; Fig. 7, the brake, connecting-rod, and pedal arrangement for operating the brake.
Arepresents any suitable frame for containing and accommodating the working parts of March 14, 12378.
and stationary shaft or axle, on which revolve the drum 0, carrying its two'gear wheels and E; also the gear-wheel Fand pinion G. V The gear-wheel F meshes into the pinion H,[ which is fixed to' shaft I, carrying the pulley K; also a friction cylinder or Wheel, R, to which the brake apparatus is applied for regulating the speed or stopping the motor. M O are connecting wheel and pinion, whereby the revolution of the wheel E is communicated to the pulley K through the medium of the pinion G, the wheel F, and the pinion H. L L are feet adjustably attached to the frame of our device, and so constructed that the frame may be attached to sewing or other machines that vary in size or height. M is a gearing, meshing into gearing-wheel D, and by which the spring is wound up. After it has performed its functions it may be thrown out of gear by the lever M. N represents the cross rod or brace running between the legs of a sewing-machine, and to which it is proposed to attach the lower part of the frame A of this device, while the upper partof the frame A is attached to the table of the machine by Y the adjustable feet L when used in connection with a sewing-machine. pedal-pressure or place for the application of power by which the brake is regulated. It is connected with the shoe-brake P by the rod P P is a ratchet, by which the degree of pedal tension may be regulated and maintained.
In the operation of my device the first requisite is winding, and this is performed by the crank M which acts to reverse the motion of the drum 0 from that imparted to it by the "action of the spring, thus by its attachment with said spring operating to wind up the spring around its fixed and stationary shaft B. The motion resulting from the uncoiL ing of the spring R is a reversal movement to the barrel 0 and its attached gearing, said reversal movement being the normal direction of movement in the machine. By attachingthe free end of the mainspring to the peripheral portion of the driving-drum O, the force of the spring is applied to better advantage than would be the case had the opposite end of the mainspring been fixed and made to turn the I represents the central shaft B, as has always been the ease heretofore, as far as we are aware.
In order to increase the driving-power of our device, it is only necessary to increase the size or strength of the driving-springs. A similar result may be accomplished by multiplying the number of driving-springs, and causing them to act together as the initial motive power.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-
1. Amotor consisting of a fixed and stationary shaft or spindle and a surrounding revolving drum or its equivalent, and a drivingspring connecting said fixed spindle and the rim or periphery of the drum, substantially as and for the purposes shown.
2. The stationary spindle B, the spring R, drum 0, and suitable gear connections with drum 0 for utilizing its revolutions when driven by spring R, substantially as and for the purposes shown.
3. The fixed spindle B, spring R, drum 0,
and gear E M O G F H or its equivalent, substantially as and for the purposes shown.
4. The combination, with the friction-pulley K, placed on any suitable shaft of the machine, the frictlon device P, P5P, and P names to this specification in the presence of two subscribing witnesses.
