'UNITED STATES PATENT OFFICE.

J. L. HUBBELL AND E. SHERMAN, OF FAIRFIELD, CONNECTICUT.

IMPROVED HAY-ELEVATOR.

Specification forming part of Letters Patent N0. 58,259, dated September 25, 1866.

To all whom it may concern:

' Be it known that we, JOHN L. HUBBELL and EDWIN SHERMAN, of Monroe, in the count-y of Faireld and State of Connecticut, have in- Y vented a new Improvement in Hay-Elevators;

and we do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, 1n-

Figure 1, a side view, the elevator in a position as transporting the hayr after it has been elevated, and in Fig. 2 the elevator in the position as raising the hay.

Our invention relates to an improvement in apparatus for raising large quantities of hay and transferring it to the desired position 5 and it consists in an` automatic mechanism, which retains the elevator in the required position until the hayT is raised, then, releasing it from that position, holds the hay suspended until it has been carried to a desired point and discharged.

To enable others to construct and use our invention, we will proceed to describe the same as illustrated in the accompanying drawings.

A is a beam, to be placed through the center ofthe barn or centrally over the driveway. B is a truck, supported upon four wheels, O, rolling upon the upper side of the beam. In the said truck is fixed the pulley D, over which a rope, E, passes, to one end of which is attached the fork F, the other over a pulley at the opposite end of the beam or other convenient place, to which power for raising is applied. On the under side of the truck is placed a latch, G, which, when the truck is in the position as seen in Fig. 2, latches onto the catch H to hold the truck in that position. I is a pawl pivoted to the truck, and arranged so that when free. as in Fig. l, it will fall upon the rope and hold the fork in anelevated position. A tail-piece, L, extends down from the pawl I, so that as the truck approaches the catch H, as in Fig. 2, the pawl I will be raised, releasing the rope, topermit the descent of the fork.

The operation of our elevator is as follows: When the fork has been inserted into the mass of hay to be raised, the elevator in the position as seen in Fig. 2, power being applied to .the other end of the rope, the fork is ra-ised until a plate, M, on the rope strikes the latch G and raises it, as denoted in red. Then the power which was employed in raising the hay draws the truck along the beam to the desired position. As soon as the truck leaves the catch H the pawl I falls upon the rope E, as seen in Fig. l, and prevents the descent of the hay elevated. When in. the desired position, the hay is discharged and the elevator returned to its first position to receive a second load.

This elevator is applicable alike to the use of all forks.

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

The combination of the pawl I, the latch G, and the catch H, with the truck B, constructed and arranged to opera-te substantially in the manner and for the purpose specified.
