UNITED STATES PATENT OFF CE.

REES O. DAVIS, OF MILAN, MISSOURI.

HAY-RICKING DEVICE.

SPECIFICATION forming part of Letters Patent No. 317,744, dated May 12,1885.

Application filed June 23, 1884. (No model.)

To all whom it may concern:

Be it known that I, REEs O. DAVIS, ofMilan, in the county of Sullivan and State of Missouri, have invented a new and useful Improvement in Hay-Kicking Devices, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawing, forming a part of this specification, and which is a perspective View of a hay ricking device to which my improvement has been applied.

The object of this invention is to improve the construction of the hay-ricking devices for which Letters Patent Nos. 276,673 and 297,234 were granted to me, dated, respect ively, May 1, 1883, and April 22, 1884, in such a manner as to more securely balance the rack in the lower part of its descent and when the load is unevenly distributed upon it, and to start the rack back when the load has been discharged.

The invention consists in an improvement of said hay-ricking device in which the balancingropes are connected with the rack, the inclined top bar, and the balancing-weight by meansof three pairs of pulleys, so that the said rack will be balanced through all parts of its movement, as will be hereinafter fully described and claimed.

A represents the base of the machine, B the forward upright, O the rear upright, D the inclined top bar, E the rack, F the rackarms, G the hoisting-rope, and H the hoisting-rope guide-pulleys, all of which parts are constructed as shown and described in Letters Patent Nos. 276,673 and 297,234, hereinbefore referred to.

I are the balancing-ropes, the ends of which are attached to the ends of the rack E. From the ends of the rack E the ropes I pass over guide-pulleys J, swiveled to the opposite sides of the lower part of the inclined top bar, D; thence around pulleys K, connected with the weight L; thence over pulleys M, swiveled to the opposite sides of the inclined top bar, D, a little above its center, and thence back to the ends of the rack E. The rack, which is supposed to carry about one thousand pounds and to go up very quickly, requires to be perfectly balanced at all points. When loaded more heavily on one side than upon the other, if at any point it should sway, the load would slide otf sidewise, and be deposited on the ground, instead upon the stack, and perhaps, also, damage the machine; but in my present arrangement, when one side of the rack is depressed by the greater weight of the load at that point the tension thereby exerted on the rope I on that side will throw the action of the counter-weight L almost or quite entirely upon that side, and thus prevent accident. Another good feature is that since all the weight is automatically made to counterpoise the rack at the point where it is required, only half of the weight employed in the machine described in Patent No. 297,23 l is needed, and as the machine is portable this of itself is an advantage, both as to cost and portability.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- In a hay-ricking device, the combination of the rack E, inclined top bar, D, pulleys J M, the counter-weight L, pulleys K, and the ropes I, each secured at both ends to the rack, passing thencejover pulleys J under weight-pulleys K, and over pulleys M, substantially as set forth. 1
