FARM-YARD DERRICK.

SPECIFICATION forming part of Letters Patent No. 614,075, dated November 15, 1898. Application filed May 31, 1898. Serial No. 682 ,165. (N0 model.)

To all whom it may concern.-

Be it known that we, CHARLES A. BANTZ and OLIVER J. BANTZ, citizens of the United States of America, and residents of Vermilion county, near Danville, in the State of Illinois, have invented a new and useful Improvement in Farm-Yard Derricks, of which the following is a specification.

This invention relates to devices for use in farm-yards for removing wagon-boxes and hay-ladders from wagons, loading and unloading salt-barrels and other heavy freight, and lifting heavy farm machinery, such as modern iron harrows, or for swinging up pork or beef in the butchering season.

The objects of the present invention include the adaptation of a simple derrick, oapable of all the uses above stated, to be operated by one man, and to provide the same with elevated racks or platforms, which are safe and suitable places to deposit wagon-boxes and farm machinery up out of the reach of stock.

The invention consists in a lifting lever having a triangular load end of peculiar construction, in combination with a fulcrum-post, and other novel combinations of parts, as hereinafter set forth and claimed.

Two sheets of drawings accompany this specification as part thereof.

Figure 1 of the drawings is a side elevation of our farm-yard derrick, showing some of the movable parts in two positions by full and dotted lines; and Fig. 2 is an end elevation or a side view at right angles to Fig. 1.

Like letters and numbers refer to like parts in both figures.

This derrick, which may be erected either in a shed or in the open, comprises a stable upright frame F, preferably four-sided and composed of slightly-inclined corner-posts, in two pairs, 1 and 2, elevated horizontal sills 3,4, and 5, crossed braces 6 above said sills, cross-pieces 7 and 8, connecting said posts 1 and 2, respectively, a pair of top pieces 9, connecting said cross-pieces 7 and 8 midway between their ends, and a pair of supporttimbers 10 parallel with said sills 3 and 4, all of which are spiked together or otherwise rigidly united. The ends of said supporttimbers 10 project, as shown in Fig. 2, and

eyebolt 17.

form fixed elevated supports a and b, Fig. 2. Between their projecting ends said timbers 10, in connection with said sills 3 and 4, form horizontal guideways for a pair of doubleended sliding racks A and B, either of which can be drawn out at either of its ends, as in full and dotted lines in Fig. 1, being pushed in to allow a wagon to drive up close to the frame F and pulled out to support a wagonbody or the like removed from the wagon after the latter is driven away. Cross-pieces 11 and 12 at the ends of the respective sliding racks form stop-cleats to coact with the sills 3 and 4' and support-timbers 10 in the respective positions of said sliding racks.

A central fulcrum-post P is supported in a step S at its lower end and swiveled at s between said top pieces 9 of the frame F. Its upper end is provided with a vertical slot crossed by a pivot-bolt 13 and a spindle 14. A lifting-lever L is pivoted on said bolt 13 as its horizontal fulcrum, and its load'end for heavy work is rendered triangular or trussed beneath by a lever-piece L fastened at 1.5 to said lever L and projecting downward and forward from this point to its load end, where it is connected with the extremity of said lever L by an iron rod R and a pair of eyebolts 16 and 17 At what may be termed its front end, Fig. 2, the lever-piece L is preferably provided with a cross-beam 18, to

the extremities of which the load-chains O are attached by eyebolts c, and from the upper ends of these bolts guy-rods r extend to said As trussed by said lever-piece L and rod R the lifting capacity of the lever L is considerably increased, and said crossbeam 18, in connection with said guy-rods 1", keeps the load from tipping when not perfectly balanced.

When it is not necessary to stiffen the lift= ing-lever L, the lever-piece L is preferably unfastened therefrom at 15, the fastening at this point being conveniently a pin coacting with a perforated fork at the extremity of the lever-piece and a series of holes in the lever L. In addition to the latter the lever L is provided at bottom with a wear-plate 19, that now coacts with an antifriction-roller 20 at the extremity of the lever-piece, which in turn is provided with a wear-plate 2l,coacting with a roller 22 on said spindle 14 within the slotted upper end of the fulcrum-post P. These devices adapt the lever-piece L to render approximately vertical the upward movement of the load as elevated by the lever L with reference to keeping it from swinging outward away from the frame F.

At the power end of the lever L it is provided with a depending handle H, loosely coupled thereto by an eyebolt 23, and a post P erected at a convenient point and provided with pins 24 and 25 to interlock with the lever L in its respective positions, serves to steady the lever in the position of rest, in which it is shown in full lines in Fig. 1, or to fasten it down, as in dotted lines in Fig. 1, when it is desired to keep a load temporarily suspended.

When a wagon-body, hay-rack,or other load is attached to the lifting-lever L (through the medium of the lever-piece L by the chains 0 at any side of the frame F, it is elevated by pulling on the handle II and with the aid of the swivel-post P may be deposited on one of the racks A and B on either side of the frame or on any of the supports (1 and b or a platform resting on a pair of said supports, or it may of course be lowered upon the ground.

Ropes with fastenings of any known or improved kind may take the place of the loadchains 0 with their terminal hooks. The loadframe F may have its corner-posts erected in bed-sills instead of in the ground, and its step S supported in like manner, so as to be portable, and other like modifications will suggest themselves to those skilled in the art.

Having thus described said improvement, we claim as ourinvention and desire to patent under this specification-- 1. In a farm-yard derrick, a lifting-lever provided beneath its load end with a leverpiece fastened thereto at the rear end of said lever-piece, and a truss-rod and connections uniting said lever and lever-piece at their extremities and rendering said load end triangular, in combination with a fulcrum-post to which said lever is pivoted.

2. In a farm-yard derrick, a lifting-lever having a lever piece detachably fastened thereto beneath its load end and connected at its extremity with the extremity of said lever-piece by a rod and eyebolts, in combination with a fulcrum-post to which said 1ever is pivoted and which is provided with an antifriction-roller to coact with the unfastened lever-piece, and an antifriction-roller at the rear end of the unfastened lever-piece to coact with said lever.

3. The combination, in a farm-yard derrick, of a lifting-lever, a lever-piece beneath the same fastened directly to said lever at its rear end and provided at its front end with a rigid cross-beam, rods and eyebolts connecting the extremity of said lever with the front end of said lever-piece and with the ends of said cross-beam, and a fulcrum-post upon which said lever is pivoted.

4.. A farm-yard derrick comprising a stable upright frame provided with elevated supports on different sides, a central swivel-post supported laterally by said frame and having its upper end slotted and provided with a horizontal pivot and a subjacent antifrictionroller, a lifting-lever fulcrumed on said horizontal pivot, a lever-piece beneath the load end of said lever, extending through said slot, detachably fastened to said lever at its rear end, and provided at this end with an antifriction-roller and at its other extremity with a rigid cross-beam, rods and eyebolts connecting the extremities of said lever and leverpiece at said load end and connecting said extremity of said lever with those of said cross-beam, means for attaching the load to said cross-beam, and means for manipulating the lever to handle the load.

5. In a farm-yard derrick, the combination with a lifting-lever andavertical swivel-post upon which said lever is fulcrumed of a stable upright frame supporting said post below said lever and provided with double-ended sliding racks adapted to be projected beneath the load end of the lever on opposite sides of the frame, substantially as hereinbefore specified.
