IMPROVEMENT IN HOISTING MACHINES.

TO ALL WHOM IT MAY CONCERN:
Be it known that I, HIRAM MOORE SMITH, of the city ofRiehInond, and State of Virginia, have invented a new and useful Improvement on a Machine for Hoisting Goods and Material in Stores, Warehouses, Depots, tc and I do hereby declare that the followingis a clear and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a horizontal section.
Figure 2 a transverse, and
Figure 3 a vertical' section, showing the frame carrying the rope, wheel, axle, and the pinions, with'the frame, crank, lite., that control them. i
The same letters refer to the same parts in each of the figures.
I construct a cylinder, A, and support it in the ordinary way, say by four posts B B B B. On one end of this cylinder I hang a double gear-Wheelproportioned to suit the business, say ordinarily, C, about thirty inches diameter, and, D, about three-fourths as large; then I have the pinion E about five inches diameter, to g'ear with C, and another pinion, If, of suitable size to gear into D, with its centre corresponding with E; E and F I hang upon a tube-shaft' G, about five inches apart, so that only one pinion can be in gear at the Same time. The two pinions and tube-shaft Gr are fitted to work on the rope-wheel shaft H, which has a feather on opposite sides working into correspondingv grooves inl tube G. The rope-wheel shai't H works in boxesJ J, in ends of iron frame K, which is securely attached to B B. Another frame, L, works inside of K, with shaft I-I passing through it, and through the pinions which are controlled endwise by L. The crank-shaft M, with wrist working in vertical groove in L, with loaded wheel N on outer end making a little over a halt revolution, is made to l move either pinion into gear. The wheel N is loaded on side corresponding with the wristo` the crank, and as it passes the crank a little beyond the dead-centre each way, secures either pinion in gear beyond the possibility ofjarring loose. v
lhemachine is operated in usual way. To shift the gear, a small rope passes over wheel N, and is made fast at a point opposite the wrist of the cran-k; the two ends pass down through the doors as low as the handrope; then, by pulling either one until the loaded wheel N is beyond vits balance,'the corresponding pinion is permanently secured in gear. I I I I do not claim the first invention of two motions to a hoisting machine. What I do claim, and desire to secure by Letters Patent, is- 4 When applied to avhoisting machine, the double wheel on the cylinder A, the two pinions combined' and 4Working on the rope-wheel shaft, the crank and loaded wheel for moving and h olcling them securely in `gear, the
whole constructed and operating as above described and set forth.
