IMPROVEMENT lIN HORSE-POWERS.

Specication forming part of Letters Patent'Na 119,279, dated September 26, 1871.

To all whom t may concern:

Be it known that I, JAMns MARSHALL, of the city of New Orleans and State of Louisiana, have invented an Improved Horse-Power, of which the following is a full, clear, and exact description, when taken in connection with the drawing aufA nexed, to which reference must be made as constituting a part thereof. o A

My improvement relates to horse-powers; and

` it consists ina peculiar construction and arrangementof parts, all of which will be more fully described in the annexed specification, reference being had tothe accompanying drawing.

In the drawing like letters refer to like parts.v

Figure l is a perspective view of my improvey ment complete and ready for use, with the eXception of the ends of the levers and the drivingshafts, by which power is transmitted. Fig. 2 is a vertical cross-section of the same.

' ln the drawing, A represents a substantial bedframe, constructed of timber in any desirable form or manner; or it may be secured to the floor of a An upright hollow column, B, having an enlarged saddle-base, B', is secured to the bedy frame A by means of bolts c c, and furnishes a bearin g, d, for the driving-gear. To this hollow column B is firmly keyed the large spur-wheel C, around which the pinion `D revolves while simultaneously revolving upon its own axis, thereby imparting motion to the stud-shaft E, which is stepped in the casting N at its lower end and journaled therein at its upper end. Upon the upper extremity of shaft E is keyed the spurwheel F, gearing into pinion G, by which motion is communicated to the vertical driving-shaft H. This shaft has its bearings in the step b on the bed-frame A, and passes through the hollow column B. On shaft H is keyed a bevel-wheel, I,

meshing into the bevel K upon the horizontal sh aft L, which is carried under the track to. any

desired place, and from a pulley at its outer end motion may be communicated to any machinery to be driven. The vertical shaft H is furthermore provided, at or near its upper extremity, with a pulley or gearing for driving machinery such as is used for ginning cotton, grinding,

thrashing, sawing, Sto.

The great advantages of my improvement over all others hitherto in use will be readily under stood, as it is very strong andv durable, as well as compact. It is also not liable to get out of order, and can be furnished at a very small expense.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

l. The combination, in a horse-power, of the large stationary gear-wheel G upon the i column B with the pinion D, shaft E, gear-wheel F, pinion G, and shaft H, all arranged substantially as and for the purpose set forth.

2. The fixed upright hollow column B having saddle-oase B in combination with theshaft H7 gear-wheel C, frame N, and levers M M, all constructed and operated substantially as and for the purpose specified.

- 3. The arrangement of the column B, frame N, gear-wheel O, pinion D, shaft E, gear-wheel F, pinion Gr, shaft H, bevel-wheels I K, and horizontal shaft L, all constructed and arranged for operation as shown and described, for` the purposes set forth.
