To all whom it may concern.-

Be it known that I, ARTHUR T. BONEY, a citizen of the United States, residing at Cairo, in the county of Randolph and State of Missouri, have invented a new and useful Hay-Stacking Derrick, of which the following is a specification.

This invention relates to derricks or devices for the purpose of stacking hay.

The invention has for its object to simplify and to lessen the cost of construction of devices of this character.

A further object is to enable the device to be readily separated and packed in small compass for transportation.

A further object is to provide a light and easily-manipulated structure of great strength in proportion to the weight thereof to enable it to resist any strain to which it may be subjected and also capable of raising the material which is to be elevated to a considerable height, thus enabling tall stacks to be built and conveniently topped off.

With these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of embodiment of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that the right is reserved to any changes, alterations, and modifications to which recourse may be had within the scope of the invention and without departing from the spirit or sacrificing the efliciency of the same;

In said drawings, Figure 1 is a perspective view of a derrick constructed in accordance with the principles of the invention, showing the lifting end of the same lowered. Fig. 2 is a perspective view showing the device with the lifting end elevated. Fig. 3 is a detail plan View showing the central portion of the tilting beam and a portion of the extensionbeam connected therewith. Fig. 4 is a detail side elevation showing the upper end of the mast and a portion of the tilting and extension beams. Fig. 5 is a sectional detail view taken through the upper end of the mast and transversely through the tilting and extension beams.

Corresponding parts in the several figures are indicated by like characters of reference.

The base of the machine consists of a sled, composed in the present instance of three runners 1 2 2, suitably connected by means of cross-braces 3 3. The central runner 1, which is provided at its front end with a clevis 1 for the attachment of draft when the device is to be moved from one place to another, supports at its rear end a mast 5, which may be connected with one of the other runners by means of a brace 6. Additional braces may be used, if desired.

When the machine is arranged in position for operation, the mast or upright is additionally braced and reinforced against tilting by means of a plurality of braces B B, each including two members-viz., a base member 7 and a guy-rod 8-pivotally connected with each other at their outer ends, where they Suitably supported upon the upper end of the mast is a cap 9, having an upwardly-extending pintle or gudgeon 10, upon which is detachably mounted the tilting beam T, which is now to be more fully described. Said tilting beam is composed of two longitudinal bars or members 11 11, which are spaced apart at suitable intervals by means of spacing-blocks 12 12 and 13 13 and connected at intervals by means of bolts 14: or other suitable connecting means; Between the spacing members 12 12, which are disposed intermediate the ends of the beam, is placed a pivot-block 15, having a vertical opening 16, adapted to engage the pintle or gudgeon 10. Said pivot-block is also provided with a transverse rod'17, extending through the sides of the members 11 and forming trunnions, the object of which will be presently described.

. Between the spacing members 13, which are disposed at and near the rear end of the tilting beam, is journalcd a sheave 18.

E designates an extension-beam which is composed of longitudinal side members 19 19,

suitably connected and spaced apart at suit-' able intervals by means of spacing-blocks 20. The rear ends of the side members 19 are spaced apart sufliciently to engage the outer sides of the tilting beam at the point where the pivot-block 15 is located, said side members 19 having forked ends 21 engaging the trunnions or projecting ends of the pin 17, being secured upon the latter by means of transverse bolts 22. Between the members 19 at the front end of the extension-beam are journaled sheaves or pulleys 23 24.

Between the front ends of the members 11 of the tilting beam is secured one end of a connecting-rod 25, the other end of which is secured between the side members 19 of the extension-beam E near the front end of the latter. By this construction the effective length of the tilting beam for hoisting purposes is greatly increased, and the tilting beam, the extension-beam, and the connecting-rod practically cooperate to form a truss, whereby great strength and capacity to resist strains will be insured, even when comparatively light materials are employed in the construction of the device.

A rope or flexible hoisting element 26 is employed, one end of the same being attached to the tilting beam near the rear end of the latter, said hoisting-rope being reeved under a pulley 27, supported near the lower end of the mast, over the sheave 18 at the rear end of the tilting beam, and finally over a guidepulley 28, connected with the mast near the base-frame, from whence the said rope or flexible element is led to the point of attachment of draft. It is obvious that any desired power may be utilized for the purpose of operating the device.

29 designates a rope or flexible element one end of which is attached to the mast at a suitable distance from the upper end of the latter. Said rope is guided under the pulley 23 and over the pulley 2 1 at the front end of the extension-beam, and attached thereto is a grappling member 30, which may be of any desired construction. The rope 29 is made of such a length that when the lifting end of the device is lowered, as in Fig. 1, there will be several feet of slack rope, thus enabling the grappling member to be conveniently manipulated for the purpose of attaching the load which is to be hoisted. When the lifting end of the device is elevated, as shown in Fig. 2, the grappling member will be raised to the extremity of the extension-beam, the slack in the rope 29 being taken up, owing to the fact that the distance between the extremity of the extension-beam when raised and the point of attachment of the rope 29 is greater than the distance between said point of attachment and the extremity of the extension-beam when the latter is lowered, as will be readily understood.

From the foregoing description, taken in connection withthe drawings hereto annexed, the operation and advantages of this invention will be readily understood by those skilled in the art to which it appertains. When the extremity of the extension-beam is lowered, as shown in Fig. 1, the grappling member may be readily manipulated to attach the load thereto. By applying draft to the extremity of the hoisting rope or element 26 the tilting beam willbe tilted, and the free end of the extension-beam will thus be elevated. When the desired elevation has been reached, the tilting beam, with its related parts, may be readily turned upon the pintle or gudgeon 10, thus permitting the load to be dropped in any desired place within the range of the device. When the draft upon the hoisting-rope is relaxed, the extremity of the extension-beam will descend by gravity. This device, as will be seen, is of extremely simple construction and may be manufactured at a very moderate expense. Its utility is not necessarily confined to the stacking of hay, as it may be successfully used for the purpose of raising loads of various kinds. The grappling member may be dispensed with or a grappling member of any desired construction may be used. When the device is not in use, it may be readily knocked down or the parts thereof disassembled,'enabling the device to be conveniently transported and stored within small compass.

Having thus described the invention, what is claimed is 1. In a device of the class described, a baseframe, a mast, braces comprising base-rods and guy-rods connected pivotally with each other near their outer ends and having their inner ends connected detachably with the mast near the lower and upper ends of the latter, and a tilting beam swiveled at the upper end of the mast.
