Description
@nitro 'tutrs gstrut @Hirn VILLIAM II. OVERHISER, OF STOGKTON, CALIFORNIA.
Letters Patent lVofGGQO, (lated July Q3, 1867.
IMPROVEMENT IN HAYELEVATOR.
TO ALL WHOM I'l MAYA CONCERN:
Be it known that I, IV. L. OVRHISER, of Stockton, in the county of San Joaquin, and State of California, have invented a new and improved Hay and Grain-Elevator; and I do hereby declare that thcfollowing is a full and exact description thereof, reference being had 'to the accompanying drawings, and to the letters of rcfer ence marked thereon. l
This invention consists of a derrick suitably supported in a portable frame, and acting in combination with pulleys aud a rope in such a manner that a pair of horse hay-forks can be kept constantly atwork stacking hay or grain or transferring grain from the stack to a threshing machine, as is hereinafter described.
To enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation.
A A represent a pair of sills or runners of stout timber, in each of which is fixed a suitable number of standards, B, andren which rests a suitable number of cross-ties, C. D represents a llat table supported by the standards B and thc cross-braces E. Frepresents a pivoted bar provided with journals at each end, which lic in boxes a', one on each sill, near the forward end thereof. G represents a derrick stepped in the pivoted bar F, supported in the usual manner by guys b, and provided with a pair of pulleys, H, at its top. A recess, c, is made in the table D for the accommodation of the derrick.' The sills, table, standards, ete., constitute a portable frame in which the derri'ck may be transported from place to place. When en route the guys and other apparatus are placed upon the table, and the dcrrick leans against the edge thereof at .the inner extremity of the recess a. i I represents a rope passing about the pulley K, placed at any convenient distance from the framework. The rope runs thence under the double block L, one part under each sheave, and thence over the pulleys H H, one part over each sheave. The ends of the rope are attached cach to one of the large 'forks M. This rope is a unit, and consequently if either side of thc pulley K receives motion the other part must also move. The motive power is applied to either part of the rope at pleasure between the pulley K and the framework, as at al. Horse-power is usually applied. Suppose one of the forks to be on the stack ready to take its load and the other to have delivered its load to a threshing machine stationed at the side of the'framework. Suppose i also that at this juncture the horse is at the point of his beat furthest from the framework at the right of the pulley K and advances toward the framework. In that case the fork on the stack is drawn toward the machine und at the same time the fork that has just delivered its load is lowered, and as the horse advances is drawn by its operator back on the stack, at which, when it has arrived, the horse has attained the limit of his beat vand the other forl has reached the proper place for delivering its load, supposing the rope to have the proper length and the pulley K to be placed at thc proper distance from the framework. On the return of the horse toward the pulley K the same process is gono through with. Thus it will'bc seen that both forks move simultaneously in opposite directions at an expenditure of power very little greater than would be required to more one and 'accomplish rdouble the amount of work that a single fork could accomplish. These results are due to the peculiar arrangement of the single rope and the pulleys and block, whereby the usual more complicated and expensive syfstcm of single or double drums and vertical and horizonal spur-gearing employed to effect a simultaneous motion of two hoisting devices in opposite directions is dispensed with. It will also be seen that the horse is not subject to the painful and wasteful process of backing.
Having thus described' my invention, what I claim as-new, and desire to secure by Letters Patent, is
The single rope I, in combination with the pulleys H and K and the block L, for the purposeof effect-ing the simultaneous motion of4 the forks M n opposite directions, substantially as described.
