HAY-RICKER.

SPECIFICATION forming part of Letters Patent No.4'7,5,200, dated May 1'?, 1892. Application filed J une 26, 1891. `Serial No. 397,658- (No model.)

T0 all whom, it may con/cern,.-

Be it known that I, MAXON CHASE, of Lucerne, in the county of Putnam and State of Missouri, have invented a new and useful Improvement in I-Iay-Rickers, of which the following is a specification.

This invention relates generally to an improved hay stacking or ricking device, and more particularly to theimproved mechanism for operating the stacking or ricking fork or head, the object of my invention being to provide an automatic mechanism that shall be safe atall times, one that shall dispense with weights, and one that shall consist of a few simply-constructed and assembled parts, requiring a minimum force to operate the Same.

IVith these objects in View my invention consists in the peculiar construction of the several parts and their novel combination or arrangement, all of Which will be fully described and claimed hereinafter.

In the drawings forming a part of this specification, Figure l is a side View of my device, the stacker-arms being shown elevated in dotted lines. Fig. 2 is a top plan View of the same. Fig. 3 is a rear view. Fig. 4 is a detail plan view showing the springactuated locking-pawl, and Fig. 5 is a detail side view of the pawl locking and unlocking mechanism.

In constructing my improved stacker or ricker I employ a base-frame or platform A, an upright frame or truss B, and the diagonal guiding-braces C C, connecting the base and upright frames A and B. Stacker-arms D D are pivotally attached to the upright frame near its lower end, and upon the outer or free ends of the said arms is mounted a stacking or ricking fork or head E, of any approved construction. A bearing platform or beam F is attached to the upright frame B near its lower end, and a short distance above said beam is a second beam F', while at the top of the frame is arranged a crossbeam G, said beams being arranged upon the rear side of the frame, and upon the opposite ends of the top cross-beam are mounted the guiding-sheaves or pulleys H H. A revoluble vertical shaft K is journaled in the beam F and top cross-beam G,sa1d shaft projecting a short distance above the top cross- .wind upon the shaft when it is revolved, thus elevating the fork or head, and in order to revolve the shaft K an operating-rope N is `wound upon the drum and adapted to be drawn by horse or other power to revolve the drum and shaft. rPhe upperface of the winding-drum is provided with a ratchet Wheel or disk O, and upon the beam F is pivoted a spring-actuated pawl P, adapted to engage the ratchet Wheel or disk, the outer end of said pawl projecting beyond the end of upright frame, and is made hook-shaped, as shown. This pawl has also a certain amount of vertical movement, the purpose of which will appear farther on. A locking-plate R is attached to the side of the upright frame adjacent to the pawl, said plate being formed with a shoulder r, which engages and locks the pawl at certain periods, and said plate is also provided with a guide-loop r', through which the releasing-bolt R works, said bolt operating to lift the pawl from the shoulder r and allow it to spring back in engagement Withtheratchetwheel ordisk. Atripping-arm T is attached to the rear end of the stacker or ricker arm D, adjacent to the bolt, the purpose of the tripping-arm being to throw the releasing-bolt upward to move the pawl out of engagement with the shoulder as soon as the fork or head has reached the ground.

In operation the hay is deposited upon the fork or head and the rope on the drum un- Wound, thereby revolving the shaft winding the elevating-ropes upon the upper portion of shaft and raising the fork or head to an upright position, thereby stacking or ricking the hay. The pawl being in engagement with the ratchet Wheel or disk prevents the shaft revolvingin the opposite direction, and thus holds the fork or head in whatever position it may be should the rope be slackened. When the fork and arms have been raised to an upright position, the arm adjacent to the hooked end of pawl engages said hooked end,

out of engagement.

Having thus described my invention, what 1. In a stacker or ricker,the combination, with the base and upright frames, arms, and fork or head, of a revoluble shaft, the elevating-ropes, Operating-rope, the pawl, and automatic locking and unlocking devices, arranged and operated substantially as shown and described.l

2. In 'a stacker, the combination, with the arms and fork, of a revoluble vertical shaft, the elevating-ropes, a ratchet-wheel mounted on said shaft, a spring-actuated pawl, a locking device to hold said pawl, an unlocking bolt, and a tripping-arm for operating 'said unlocking-bolt, substantially as shown and described. v

3. In a stacker, the combination, with the arms and fork, of a revoluble shaft, the elevating-ropes, a ratchet-disk, a spring-actuated pawl having a hooked end, a combined locking and guiding plate, a releasing-bolt working in said guide-plate, and a trippingarm attached to the stacker-arm, substantially as shown and described.

4. In a stacker, the combination, with the arms and fork, of the revoluble vertical shaft, the elevating-ropes, the winding-drum, the operating-rope, the ratchet-wheel, springactuated pawl having a hooked end, the plate having a locking-shoulder and guiding-loop, the releasing-belt working in said loop, and the tripping-arm attached tov one of the stacker-arms to operate the releasing-bolt, substantially as shown and described.

MAXON CHASE.
