Description

AM. PHOTO-LITRO. EB. KY. (OSBORNR'S PROCESS) UNTTED STATES PATENT OEErc e@ JOHN H. WAI'II, OF PORTSMOUTH, OHIO.
IMPROVEMENT IN DEVICE FOR CHANGING SPEED.
Specification forming part of Letters Patent No. 53,202, dated March 12S, 1866. A
To all whom it may concern:
Be it known that I, JOHN H. WAIT, of the city of Portsmouth, Sciota county, Ohio, have invented a useful Improvementin Devices for Changing Speed; of which the following is a clear description thereof, reference being had to the accompanying drawings, and letters of reference marked thereon.
My invention relates to a series of conical gear-wheels so arranged as to readily admit of a change of speed in whatever mechanism it is applied to.
Figure 1 isa plan of my improved device for regulating or changing speed. Fig. 2 is a side or end view of the same.
A is a frame which bears the axles a, ct. Upon the axles (t a' is a series of conical gearwheels, I; b. Between the series of gearwheels are two parallel rods, c c', firmly secured to the frame A, upon these rods c c', a movable frame, d, having two conical gearwheels e e', which engage, respectively, the series of gear-wheels b b The movable frame d is thrown to and fro by means of the lever f, which may be locked in any desirable position by the check-plate g. To the axle a is attached the crank h. Thel axle c is prolonged.
2. This ratchet is secured to the gear-wheels.
rIhe end ofsaid ratchet catches into a notch or groove in shaft, thus' preventing the rotation ot' the machinery except in one direction. The diagonal position given the parallel rods c c in the frame A depends upon the amount of con vergencc of the gear-wheels. The amount in the change of speed depends upon said convergence and variation in number ofteeth, the lesser wheel in cone always fast on shaft.
Having described my invention, I make the the following claim:
The series of conical gear-wheelsb b', in combination with the movable frame d and two conical gear-wheels, e e', arranged as above described, and for the purpose set forth.
JOHN H. WAIT.
