Letters Patent No. 95,440, dated ctober 5, 1869.

IMPROVED `rimasti-PoWHR.

The Schedule referred to in these Letters Patent and making partof the same.

To all 'whom it may vconcern Be it known` that we, JOSEPH DIFFENDAL and SAMUEL HUGHES, of Westminster, in the county of Carroll, and State of Maryland, have invented a new and useful Improvement in Horse-Power; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable those 'skilled in the art to make and use the same, reference 'being had to the accompanying drawings, forming part of this specification.

The object of this invention is to provide a simple and compact arrangement of multiplying wheels in a portable horse-power for producing a rapid motion for the tumbling-shaft, from the first mover, with the least possible amount of lateral pressure on the drivingshaft,

The invention consistsin the particular construction and arrangement of parts', as-hereinafter set forth.

Figure 1 represents a plan view of our improved horse-power, and

Figure 2 represents a longitudinal sectional ele-va` tion, taken on the `line x x'ofg. l.

Arepresents a rectangular frame, or,it `may be of other form, in the centre of whichis mounted, on a short hollow shaft or sleeve, a, a spur-wheel lC.

The upper end of this shaft is made square to admit of the connection of the sweep D, which is held thereon by a screw-threaded nut, c, the lower end of the shaft being flush with the lower face of the wheel C.

B is a solid cylindrical shaft, stepped at b, and having the bevel-'gear wheel H arranged loosely thereon, and passing up through the tubular shaft a, as show in the drawings. y

The wheel C gears with two pinions, E, one on opposite sides, also on vertical shafts., and connected with spur-,wheels F, which gear into a' pinion, G, working loosely on the main shaft B, and connected to a large bevel-wheel H, rear-ing with the bevel-pinion I, on the tnmblingshaft. v

The Object of the arrangement of the pinions E and spurwheels on bothV sides of the master-wheel c and pinion G, is to take Off the lateral pressure from the shaft B, which exists wheuonly one set is nsed,`f which, by this arrangement,is divided between the two sets and wholly removed from the said main shaft, thereby making a much more easy running and durable. apparatus than when arranged with onlyone set of intermediate set of gears E E. f

1t will be observed that while the journals of the vshafts on which the wheels E -are mounted are thus pressed equally outward, so as to rotate with the minimum amount of friction, the arrangement of parts is such that the wheels H and O, andlikewise their shafts, rotate in the same direction, thereby allowing the freest possible movement, with the least wear, friction, or consequent unnecessary expenditure of motive or impelling force.

Having thus described our invention,

What we claim as new, and desire to secure by Letters Patent, is

1. The arrangement, in the horse-power frame herein described, ofthe wheels H C, and the short hollow shaft a and solid shaft B, with relation to each other, as

shown, whereby they are adapted to rotate together in the same direction, for the purpose specified.

2. The described arnngement of the wheels O H, hub G, pinions' E E, and spur-wheels F F, whereby thejournalsofthe latter have an even'bearing, as and for the purpose specified. I y

3. In combination with theframe A of the construction shown, the short tubular shaft a, solid shaft B large spur-wheel C, large bevel-gear wheel B and its hub G, the large spur-wheels F F, and pinions E E, all constructed, arranged,'and operating together, as
