HAY-CARRIER.

SPECIFICATION forming part of Letters Patent No. 323,858, dated August 4, 1885.

Application filed May 11, 1885. (No model.)

To all whom it may concern:

Be it known that I, JOHN P. DAVIS, a citizen of the United States, residing in the city of Rockford, in the county of Winnebago and State of Illinois, have invented a new and useful Hay-Carrier, of which the following is a specification.

This invention relates to a class of machines employed in connection with power-forks to unload hay from wagons and deliver it to the place of deposit.

The object of this invention is to improve this class of machines, to render them more efficient, to simplify their construction, and

produce at a small cost a reliable machine,

made reversible and capable of use in opposite directions on the same trackway without change of the vehicle thereon.

To this end I have designed and constructed the apparatus represented in the accompanying drawings, in which- Figure 1 is an isometrical representation of a machine embodying my invention, and Fig. 2 is a lengthwise vertical central section.

In the figures, A represents the horizontal under plate of the vehicle-frame of a carrier produced in rectangular form in plan, and from the several corners of this rectangular plate rise vertical arms B, connected on the 0 lengthwise sides of the horizontal plate by means of vertical flanges O, which serve to strengthen the frame. The upper ends of the vertical arms B are provided with traveling wheels D, supported to revolve on stud-jour- 3 5 nals projecting from the inner face of the arms. These traveling wheels D engage the upper face of a trackway consisting of a suitable beam, E, supported in the required position in any suitable manner.

At F is represented the horizontal plate or bar portions of the swivel portion of the carrier, which is rectangular in plan, and from one end of this plate or bar portion F arms G depend to receive a rope-sheave, H, supported to revolve between the arms on a suitable journal passed through the depending ends of the arm G. The opposite end of the plate or bar portion F from the sheave-supporting arms are provided with depending ears I, and o a vertical flange, K, connects these cars 1 with the depending arms G on each side, and serves to strengthen the plate or bar F. This swivel portion is swivel-jointed to the horizontal plate A of the vehicle centrally by means of a swivel screw-bolt, L, passed centrally through the parts, and, by means of a screwnnt on the bolt, serves to hold the parts in such a manner as to permit it to turn on its swivel-connection to reverse its ends.

At M are represented flanges depending from the end portions of the horizontal portion A of the vehicle and form grooves to receive the ends of the swivel.

At N is represented a lever-detent of latch form, pivoted to the vertical side flange, G, of the vehicle, and is fitted with an arm, 0, which extends through an opening in the horizontal plate A into an opening in the swivel-plate F, to hold the parts in their adjusted position, but is capable ofbeing disengaged from the swivelplate to permit its reversal.

At 1? is represented a double pawl-lever pivotally supported between the depending ears I, to oscillate vertically. The heel end P of the pawl-lever is fitted to engage the central notch, P, of a double-inclined stop, P, fixed to the under face of the track-beam; and the toe end It of the pawl-lever is fitted in serrated jaw form to engage the hoistingrope R, passed over the sheave H, to prevent it running over the sheave.

At S is represented a link pivotally connected with the pawl-lever at a point slightly forward of its pivotal connection with the ears I, in such a manner that the Weight on the hoisting-rope connected therewith will tend to hold the toe of the pawl-lever in contact with the rope and its heel in contact with the stop.

At S is represented a sheave supported to revolve on a suitable journal-bearing within a 0 yoke, S, which isprovided with a swivel-hook, S, to connect with a suitable fork. One end of the hoistingrope R is fixed to the link S in the double pawl-lever, from which point it is passed under the sheave S in the yoke, thence 9 5 over the rope-sheave H, to connect with the power employed to operate the machine.

By this construction and arrangement of the several parts it will be seen that with the parts in the position represented in the draw- 10o ings a weight connected to the swivel-hook S will operate to hold the heel of the double .the direction of the arrow.

pawl-lever in the notch of the double-inclined stop and prevent movement of the vehicle on the trackwa-y; and this connection of the heel of the lever with the stop also serves to hold the toe of the double pawl-lever disengaged from the hoistingrope, to permit it to be drawn freely over the sheave by force applied to its free end, and this movement of the hoisting-rope will elevate the sheave S and the weight thereto attached and cause the pulley to engage the double pawl-lever and disengage its heel end from the notch in the double-inclined stop and permit the vehicle to move on the trackway in As soon as the heel of the double pawl-lever is over the double-inclined stop, the weight, by reason of its connection with the lever forward of its pivotal connection, will operate to depress the serrated toe thereof and cause it to engage the rope and prevent its running from the sheave. The continued pulling on the free end of the rope will then cause the vehicle to travel on the trackway to the place of deposit. After the hay has been deposited, the return movement of the carriage will cause the heel of the lever-pawl to engage the inclined portion of the stop, and will disengage the toe thereof from the rope, and will enter the central notch to hold the vehicle in position and permit the fork to descend to be again loaded.

hen it is desired to operate my improved carrier in the opposite direction 011 the trackway to that hereinbefore described, it is only necessary to disengage the lateh-detent 0 and reverse the swiveled portion connected to the upper or traveling portion to the position opposite that shown in the drawings, when the machine will be fully fitted to operate in the direction opposite that indicated by the arrow.

I claim as my invention- 1. The combination, with the swiveled ropecarrying portion of the carrier and with the double-inclined stop having a central notch, with its base projecting beyond the under side of the beam to which it is secured, of a double pawl-lever having a heel engaging said double-inclined stop, substantially as set forth.

2. The combination, with the double inclined stop having a central notch, with its base projecting beyond the under side of the beam to which it is secured, and with the rope-sheave, of a double pawl-lever to engage the hoistingrope, and the double-inclined stop, substantially as set forth.

JOHN P. DAVIS.
