IM PROVEMENT IN HORSE-POWERS.

Specification forming part of Letters Patent No. 204,] 85, dated May 28, 1878; application filed April 10, 1878.

.have invented certain new and usefuLImprovements in Horse-Powers, of which the following is a specification:

Our invention relates to that class of horsepowers in which the power is obtained from one or more horses attached to the ends of levers or arms projecting from a wheel or shaft having a vertical. axis, around which the horses walk in a circle. Horse-powers of this old style are extensively used for driving cottongins and other machinery which is located on the second floor of a building.

Adjustable gearing, central supports, and various other expedients have been devised to overcome the difficulties arising from the carrying of loads on the second floor, which interferes with the operation of the horse-power as ordinarily constructed, and frequently causes damage or breakage of machinery. We overcome the difliculty by providingaframe independent of the building-timbers, except at one end, where it is firmly supported by posts, which frame remains stationary, while the timbers forming and supporting the upper floor may rise and fall with a varying load without affecting the independent horsepower frame or the machinery attached there to, at the same time retaining the old style of machinery, which is simple, cheap, and easily kept in order.

Our invention further consists, in combination with the said independent-frame horsepower, of rolling tooth-gearing, which adapts itself to any irregularity or change in the position of the parts, and works successfully even though the shaft be out of line.

In the accompanying drawings, Figure 1 is a perspective view of our independent-frame horse-power as applied Within a building. Fig. 2 is a vertical section of the same. Fig. 3 is a perspective View, on a larger scale, of parts of the rolling tooth-gearing. Fig. 4 is an elevation of modified construction, and Fig. 5 represents detail views of the same.

A A represent timbers constituting parts of the house-frame. B B are beams, attached to the cross-plate A by bolts at d, independent of the main frame. Said beams are placed at a suitable distance apart, to allow the drum or pulley K to revolve between them, and are connected together by cross-ties, as follows: O is the cap or head-block, to which the combined box and bearing D are attached to support the end of master-shaft F, to which also the hanger and box E are attached to support the end of counter-shaft H. G is "a bridge-tie, on which the other end of shaft P; or the same object may be effected, as illustrated in Fig. 4, by means of chafingplates and set-screws a a secured to beams A A and end of cap or head-block C, as shown in Fig. 4, so as to allow the timbers A A to rise or fall as the weight on same may be diminished or increased without disturbing the gear of the machine. We also propose to use a bolt, b, with spiral spriu g attached to A and O, as illustrated in Fig. 5, to prevent swinging frame from tilting.

M is the master-wheel; F, shaft for same,

secured as before described. H is countershaft, on which the pinion his fastened, working in segment t on master-wheel M. The bolt b and spring a are shown in detail, also the combined box D and gudgeon for shaft.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The combination of the vertical mastershaft F and the independent frame B B, substantially as and for the purpose set forth.

2. The box D, cap 0, and beams B, combined, substantially as set forth. 3. The combination of a vertical-shaft horsepower, FM, an independent frame, B B, for unto set our hands this 24th day of Novemsupporting the upper journal of said horsepower, and building-frames A A, to which the horse-power frame or beams B are secured at; one end, leaving them independent of said building-frame at the other end.

In testimony of which invention we hereber, 1877.
