\VILLIAM FRANKLIN BRIAN, OF PARKVILLE, ILLINOIS.

HAY-DERRICK.

SPECIFICATION forming part of Letters Patent No. 335,888, dated February 9, 1886. I

Application filed December 8, 1885.

To aZZ whom, it may concern:

Be it known that 1, WILLIAM F. BRIAN, a citizen of the United States, residing at Park-- ville, in the county of Ohampaign and State of Illinois, haveinvented certain new and use ful Improvements in Hay-Derricks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it ap' pertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l of the drawings'is a side view of my hay-derrick. Fig. 2 is a front view.

This invention relates to hayderricks de signed to be used in building hay stacks or ricks in the field; and it consists in the construction and novel combination of parts, as will be hereinafter fully described, and particularly pointed out in the claim.

Referring by letter to the accompanying drawings, A designates the bed-frame, which is mounted on a rigid gear-axle, B, and is provided with a rigid bolster, O, at its front end, which is connected to the front axle, D, by a king-bolt,E,in order that the front axle, D, may be turned to guide the truck. F are the wheels, which are made suiliciently small in diameter to permit the truck-frame A to come near enough to the ground to bring the elevatingrope low enough to be conveniently operated. A derrick-frame, G, is built upon the truckframe A, and is provided with aplatform, H, at its upper end, which is provided with an opening, I, a little to one side of the center, and the derrick-pole J has its upper bearing in this opening or hole I. The lower end of the derriclcpole J' is stepped in a seat, L, made in the middle of the cross-bar M, Sc cured upon the sills N N of the truck-frame midway their ends. At its upper end the derrick-pole J is provided with an inclined bar, 0, the longer arm 0, of which extends upwardly and the shorter arm, 0 of which extends downwardly. Braces P I connect the inclined bar 0 with the derrick-pole, and serve'to strengthen the said inclined bar 0. At or near its upper end the inclined bar 0 is provided with a pulley, P, which depends from Serial No. 185,070. (No model.)

the under side of said bar 0. The platform H is provided at its rear edge or side with a pulley, Q, and the cross-bar M is provided about midway ot'itslength with a pulley, R. Nearits lower end the derrick-pole J is provided with a short horizontal bar, S, the longer arm of which is provided with a horizontal lateral slot, T, through which the portion U of the hoisting-rope V passes. The end of the portion U of the hoistingrope is provided with a slotted wear-plate, \V, and a knot, N, is tied in the end of the portion U, to prevent the rope from drawing through the plate and slotted arm. The portion V of the hoistingrope passes under the pulley It, up and over the pulley Q, and thence over the pulley I, and is passed down to and connected with the hayt'ork. The horse is hitched to the loop .2 at the junction of the portions V and U of the hoisting-rope. The location of the knot can be changed to shorten or lengthen the portion U, of the hoisting-rope, and this por tion U, when the rope is drawn out taut, causes the derrick-pole to turn in its bearings, and carries the inclined bar 0 around onefourth of-a circle, at which time the fork is tripped by an attendant, and the forkful of hay is deposited at the desired point, whereit may afterward be manipulated to form the stack or rich. The short horizontal bar S is provided with a short metal piece, X, which is pivoted to the face of said arm, and is intended to permit the rope to be wound around it to hold it when not in use.

Having described this invention, what I claim, and desireto secure by Letters Patent, 1s-

The combination, with the truck and derrickframe, of the derrick'pole having the inclined bar at its upper end and the slotted horizontal bar near its lower end, the pulleys P Q, and R, and the hoisting-rope having the portions V and U, the latter being knotted at its end, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

\VILLIAM FRANKLIN BRIAN.
