IMPROVEMENT IN HORSE- POWERS.

Specification forming part of Letters Patent No. 37,350, dated January 6, 1863.

A the pinion-shaft nearly free from friction in the journal-boxes.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct the master-wheel A, Fig. 1, and wooden frame of my horse-power in the usual manner, (which I do not'claim.) I then construct two horizontal crown-wheels, B B, Figs. l and 2, of equal size, and having the same number of cogs in each of them; I regulate the number of cogs, more or less, as circumstances may require it. The diameter of the crown-wheels must be sufcient to bring the edges of them nearly together, or over each other, in the center of the horse-power, one of which crown-wheels must be inverted so that they will each of them work in the pinion, at thesame time, on opposite sides of it, and turn in opposite directions. The pinion D,

Figs. l and 2, on the horizontal shaft c, Figs. 1 and 2, I bevel from the middle toward each end, as shown at D, Fig. 2. I use rollers G G, as shown at Fig. 2, to keep the crownwheels in gear where they work on the pinion, (which I do not claim.) The shaft C, Fig. 2, is secured to its place by journal-boxes, as shown at F F, Fig. 2. The object in placing the pinion between the two crown-wheels is to prevent friction, the upper crown-wheel pressing the pinion downward, and the lower crownwheel pressing it (the pinion) upward, thereby equalizing the pressure from the crownwheels and relieving the journal-box F, Fig. 2, nearest to the pinion of much of the friction that would result from having the crownwheels work only on one side of the pinion, as they are now used; and my arrangement leaves the other journal-box F at the end of the frame almost free from friction. Consequently I have a gain of power, so that fewer horses will be necessary to operate my horsepower than are required for those having a pinion below each of the crown-wheels.

WhatI claim as myinvention, and desire to secure by Letters Patent, is

The application of two horizontal crownwheels, B B, placed on each side of the center of a horse-power, in combination with a single pinion, D, beveled each way from the center,

and working between the two horizontal crown-wheels B B as and for the purpose substantially as specified.
