HAYQDERRICK.

SPECIFICATION forming part of Letters Patent No. 380,206, dated March 2'7, 1888 I Application filed October 5, 1887. Serial No. 251,547. (No model.)

To all whom it may concern:

Be it known that I, ABRAHAM LINCOLN KANE, a citizen of the United States, and a resident of Middle Fork, in the county of Hocking and State of Ohio, have invented certain new and useful Improvements in Hay-Derricks; and I'do'declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains 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 1 of the drawings is a side elevation of my improved hay-derrick. Fig. 2 is a transverse section of block H. Fig. 3isatop view of extension-bar 6. Fig.4 is a transverse Fig. 5 is a vertical longitudinalsection of standards 0, O, and D, showing slot '0.

My invention relates to improvements in I derricks, especially such as are used in handling hay or straw; and .it consists in the construction and novel combination of parts, as

. hereinafter set forth.

Referring to the accompanying drawings,

A represents the base-frame ofthe machine, composed of the beam at and the similar beam, b, secured across the beam at at right angles thereto. (The ends of the beams may be provided with loops or openings through which pins may be driven into the ground to retain the base-frame in place.)

0 O are similar standards rising centrally from the beam b, and D is a beam fitting between the standards 0 O and rendered adj ustable by the longitudinal slot 0 and the bolts and nutsc',the nuts being provided with han- 0 dies and the bolts passing through the slot and the openings 01 in the beamD and the lifting devices, hereinafter described. A

E is a brace-rod secured at its upper end to the center of the top of the standard 0 and 5 at its lower end to a pin, F, driven into the ground at a point to the rear of the beam A.

e e are brace-rods similar-to the brace E, secured at their upper ends .to opposite corners of the standard 0 and at their lower ends to the pins F f f in the ground forms an equilateral triangle, so that the frame composed of the beams on b and standards 0 G is equally braced the arms of the bifurcation are provided with journal-bearings h h.

I is a working-beam provided on its sides at opposite points with the trunnionsirgwhich are-journaled in the bearings h h. The arm of the working-beam which raises the load has resting upon it a longitudinally-slotted beam, 5', which can be moved in or out, so as to extend said arm, and can be secured'in its adjusted position by the bolt 1?,passing through the slot in the extension and through a suitable opening in the arm. 7

i is a chain connecting the beam D below the plate G and the arm of the working-beam near the pivotal point of the latter tolimit the upper motion of saidarm.

J is a standard rising at right angles from the working-beam betwe'en'the trunnions, andhaving the metal cap j secured to its top.

' K isa. truss or brace rod,' which passes through a groove in said cap and'has its ends passing through suitable openings or attachments in the opposite arms of the workingbeam and tapped therebelow to engage the nuts k k, by means of which the rod K can be tightened and the working-beam more strongly braced. I p v L is a hay-fork of ordinary construction, provided with the tines Z l, and connected by the rope or wire M with" a hook, m, attached to the arm of the extension-beam i of the working-beam, which arm stands outward on the same side of the beam D as the brace-rod E.

N is a cord attached to the hay-fork, and by means of which a person stacking hay or straw can draw the longer arm of the workingbeam to any desired point, and N is a cord attached to a trigger, a, for the purpose of allowing the tines to drop and release their load.

0 is a hook secured to the end of the shorter front arm of the working-beam and supporting a block, 0, provided with the sheaf P.

p is a rope secured at one end to a staple fixed upon a suitable point on the standard 0 and passing thence over the sheaf P.

Q is a block provided with a sheaf, q, and a depending stem, 1', which is pivoted in a suitable opening in the center of the base.

The rope p descends from the sheaf 1?, passes under the sheaf q, and has the whiffletree S secured to its forwardly extended end, as shown.

It is evident that a horse hitched to the whiflletree, when moving forward, will raise the long rear arm of theworking-beam and raise any load that may be attached to the fork, and also that the working'beam, by means of the trunnioned bearing-block, can be swung to any desired horizontal angle.

The swiveled block Q permits the line of draft of the rope to correspond with any angle between the braces e e.

T is a rack secured to the side of the beam D, and U is a lever pivoted to a link, u, which is itself pivoted to one of the side standards,

0 or 0'. By means of the lever and rack the beam can be raised to different heights.

V is a detent pivoted to one of the standards. and t is a spring attached forcing the detent into engagement with the rack,

To raise the beam D, the bolts 0 must be loosened and tightened again when said beam is adjusted.

Having described my invention, I claim- In a derrick, the combination of the base, the standards 0 O, the longitudinally-slotted beam D, the set bolts and nuts provided with handles, the rack T, the pivoted lever U, the

link a, the detent V, and spring 0, substantially as specified.

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