IMPROVEMENT IN HORSE-POWERS.

The Schedule referred to in these Letters Patent and making'part of the same.

To all whom it 'may concern:

Be it known that I, C. H. GIFFORD, of' Potsdam Junction, in the conntyof St. Lawrence, and State of New York, have invented a new and useful Improvel ment in Horse-Powers; and l do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying"drawing, forming part of this specication.

l'lfhis invention relates to a new and useful improvement in horse-powers, for driving threshiug-machines and other machinery, and for all purposes to which it is applicable; and l It consists in the construction, arrangement, and combination of parts hereinafter described.

The Vaccompanying drawing represents a vertical longitudinal section ot' a horse-power, constructed according to my invention.

A represents a stationary internal gear-wheel, which is attached to the top ,of the central post, B.

CV is the bedor platform, by which the post B is supported. Y

D is the driving-lever or sweep, to which' the power or team is attached. l

E E are driving-wheels, which mesh into the interna] gear-wheel A, and. revolve on studs in the lever'D.

These driving-wheels also mesh into a. central pinion, F, which is fast on the sleeve G of the bevelwheelH. This sleeve passes through lthe lever D,

central pinion E and bevel-wheel H, proportioned to thediameters of the wheels engaged, or about four, moreor less, revolutions ofthe bevel-wheel H, to tle liorses one. y

Wheels of any other desired proportions may be used.

I is a bevel-pinion, on the line-shaft J. This shaft is revolved in boxes on the stands or pillow-blocks y K K, on the bed or platform C.

rlhe bevel-wheel H engages with the pinion I, and here the speed is increased in proportion to the dili'eren'ce in the diameters of the two wheels.

L is a pulley, on the end ofthe shaft J, from which motion is conveyed by a belt to drive the desired piece of machinery.

The driving-wheels E E may be made stationary, and the lever may he attached to the internal gearwheel A, if desired, but I prefer 'the arrangement shown, as being best adapted to the purpose.

It will be seen that by this method ot' combining and arrranging the wheels, the strain is eqnalized, and the power rendered stronggiud durable.

Having thus described my invention,

I claim as new, and desire to secure by Let-ters Patent- The arrangement of the wheel A, driving-wheels E 1*), centre pinion-wheel F, bevel-wheel H, and pin- Witnesses J. RAYMOND, ROBERT RoDGERs.
