"IMPROVEMENT I N HAY ELEvAToR'AND STACKER.

Specificationtorming part of Letters Patent No. 48,742, d'ate'd] nl-y-ll1865.l

.Toull whom it may concern Beit known that I, A. W. TOOKER, of Harvard,countyof McHenry, and State of Illinois,

have invented a new and Improved Stacker; end I do hereby decla-re that the following is a full, clear, and exact description thereof, reference being had to the accompanying draw` ings, making a part of this specification, in which- I Figure lis a perspective vie'w of my stacker complete. Fig. 2 is an elevation of the stacker and a section through its base. Fig. 3 is a top Y view-'of the stacker. `Fig.4 is a hitching-clasp used for attaching the horse to the draft-rope.

Similar letters, of reference indicate corresponding parts in the several figures.

This inventionfrelates toan improved mode of vconstructing that class of stackers in which the horse elevates the load and swings the same over and upon the stack iii-moving oft from the machine, and then causes the fork te returnto its original position for receiving another load in returning toward the machine againf 'The object of my invention is to secure lightness and portability, and atl the same time posed of two longitudinal sill-beams, a a., secured together by. means of transverse sillsb b', which are'tenoned into the sill-beams a a. y Upon this foundation-I erect a tripod composed.

of three inclined beams, c, secured at their lower ends to one of the sills, b, and to thelongitudinal beams a a, as shown clearly in Fig. 1. The upperends of the beams c are secured together by means `of a cap-plate, d, a portion of which constitutes ai bearing for the pivot of the upper brace of the crane. Thelegs of the tripod are spread apart at their lower ends, so

that they a'ord steadiness to the machine and allow the crane-arms to have all the swinging motion required. y The crane is composed of two beams or arms,

g g', inclined at about the angle represented in Figs. 1 and 2.. The beam g has a vertical pin, It, formed on' itsloweriend, which pin may be shod with metal and stepped'inametal bearing inthe central transverse sill, b. "The upper end of this'beam gis suitably secured to the beam gl at an intermediate point between the ends of the'latter. The lowermost end ot "the beam g has avertical pin,., applied to it,

which enters the vertical hole through the capplate d, and constitutes a pivotV for the upper portion of the crane, and also a'hook or staypin for supporting the cra-ne and connecting it to the tripod.

By thus constructing the frame-work of my stacker I am enabled to dispense with a cen- ,tral revolving post, and to dispose the beams in such manner that they will'reeeive theweightm' ofthe load upon them to `the best advantage.

The supporting frame or tripod becomes a brace for steadying the machine while elevating a load, and the inclined beam g becomes a prop for sustaining the weight brought upon or suspended from the jibv or swinging beam gl. vI am thus enabled to employ very light 'beams and to make thestacker sufficiently portable to serve a practical .purpose as suc The stacker, when thus constructed, is rigged as follows: A rope,'h, is passed overa sheave,

k, at the outer e.nd.of the beam g.' and carried to a pulley-block, l, which is attached to the central siILbeam, b', thence around one of the .legs of the tripod and across the foundationframe to another pulleyblock,m, through which the rope is passed and carried oft' to the in` clined beam g, to which it is fastened at n. The;`

rope'h' is carried from the point n to one of the legs ot' the tripod and passed over a pulleyof block p, and to the pendentrend of this rope a weight, s, is applied, which should be suiiciently heavy to swing the crane-arms back to the position represented in Fig. 1 after the dis-l y charge of a load.

To operate my machine the horse' is hitched vto a hook, A, which is secured by means of a loop, t, and pivoted tongue v to the rope la-asv shown in Fig. 1'. That portion ofthe rope 7a' which 'extends from the pulley m to the hitch; ing-hook A is slack until the load .of hay-'has been elevatedv to a sufcient height to allowit pass freely over the stack. When this oc. curs the further movementof the horse will takeup the slack rope and swing the load or crane round over the stack. This adjustment;

may be made'very readilyl with the bitchinghook which l have represented in Fig. 4. p

Having thus described my invention, what 1 claim as new, and desire to secure by Letters 1. 'The combiuatlon of the crane-beams g g' with a tripod, which is supported upon a foundation-iframe, 'when said beams are supported by and applied to their frame, substantially as described.v

2. The arrangement of the rope h upon a stacker, which is constructed without; a central turning-post in such manner that the movements of the horse can be made to effect the raising of the load and the turning of the cranel arms,'substantially as desoribedf 3; The use of an adjustable bitching-hook, A, in combination with a crane, gl g', or its equivalents', and the rigging h', arranged lto operate substantially in the' manner and for the purposedescribed.

Witness myhaud i'n the matter of my applica tion for 'a patent on a hay elevator and stackj er this' 9th 'day of February, 1865.
