IMPROVEMENT `nv HAY-nLrzvnroR Arm conversa.

The Schedule referred vto in these Ietter-Eatent end malclng pvurtofthe A same.

I, CHARLES. A. Minnen, of the township of Ma-v rengo, in the county of Calhoun and State of Michigan, have invented certain Improvements in Hay Elevators and Conveyers, `of which the lfollowing is a specification. i g

My invention relates to certain modifications vin the arrangement andlconstruetion of the'timber ways,

carriage-truck, and other apparatus for elevating and conveying hay, Ste., into barns, the object being to simplify the parts, and arrange them .more compactly in a vertical line, for bettery adaptation to barns of every kind and capacityi The accompanying drawing exhibits my invention- Figure 1 being a perspective view (broken) where the arrangement is shown as applied to elevatehay `from the outside of a horse-barn and conveyit through a window or door opening to the mow.

vFigure 2-i'sa partial side elevation of, truck with runner guides.

Figure 3 is aperspective view of a two-whecltruck 4 without runners.

'A A are two parallel track-tinibers, framed with head-blocks, B B, and designed to extend through the interorofl the hay-mow, and, in the ease of a horsebarn, toproject throughthe opening' o, to a sufcient distance from theface fof the building-so that the truck C may run close past the transom d, outside,`

for the purpose of elevating the hay vertically, or nearly so, from a wagon below.

The truck yO may be simply a-pair' of small wheels, hung loose. on an axle, shown at e, e, and 1a, whichi with two branching' Shanks, which' are hooked on or wrapped around the aisle a, so as to leave its central part uncovered, for thepurpose of engaging .with the dog-hook m, to dog the truck tothe outer head-block during the action of "elevating the hay.

The shank of the dog-hook may slide up and down,V

between staples, or other guides, fastened to 'the outside'head-block,faud the 'hook lifted up, so as 1go-.disengage it from thc axle and liberate the truck at the proper moment, by means of a knob or disk, a, on4

the rope, next to the fork (not shown) striking against the hook, through 'the intervention of a bend inthe shank, or of a jointed arm, 7`,'but in either case it is best to fork the end, so that the rope may passbe tween without fn ying, and theknob'or other device.v

on the rope strike squarely.

When hay is elevated' from the interior ot large barns, where it has to beconveyed, in the mow, over ,crossbeams,&c., it is necessary to suspend the trackway at a height suitable to .the requirements of lthe Y cascand to suspend the'load directly from thetruck.`

Aforth.4

For 4such application, I provide the. pulley-block p with two canigshaped projections, as shown attili, between'which the hoisting-rope works, and to surround therope, at a proper point, with a bulb, l), which, 1u

4hoisti-ng,`slides over the surfl'tce 'of the earns. lhen -the 'rope and bulb spring in over the shelf of the cams, and, when the truck is liberated, the weight of the loaded fork is 'transferred from theshcave lto .the

block. y

`The loaded fork being thus conveyedto the desired point, and` trippedv and discharged, the empty fork and truck may' be returned, as usual, by rolling down the incline of thetrack-Way, or by the aid of a cord, which, (when the track-wheels are stopped by the abutment Bof' the head-block) will be pulled by the operator, so as to disengage the bulb. from the pulley-block cam, and the fork will descend for a fresh load.

The truck is redogged to the head-block by the axlepassing undor--thcneliuedterminatimlot'l-the hook and raising it, when it falls, tol again clasp the axle, nntilthe next load is'"elevated.

The rope R passes up from the fork Athrough the4 pulley-block p, thence along the track .over the ,pulley p', and, passing down, is guided outside by other pnl- Ieys(uot shown,) and there hitched tothe team, and manipulated-in the vordinary.way. N l

The tracks A A are usually suspended -froin the barn-timbers by hooked rods and staples, s s, in a portable manner, and my object is to make the arraugement compact ina vertical direction, to alord'room Vfor ,t-he-4 loaded fork to pass, inthe line of the track,

lthrough the ordinary side openings in horse-barns to the mow, and in a manner to make it equally el'eetive for .other and general use. f

Any ehange,ltherefore, in the construction-of; the

truck, which merely involves an increase of horizontall space occupied, is unimportant.

For instance, a pair of' runners, 1' rfmay, under certain con'ditions, be useful, when projected from the axle of a two-wheeled truck to steady it, and the pulleyblock hung-close up t-o a lcross-bar between the 1'-un' Inels, as shownl in figs. l and 2, or `the truck may be hung on four wheels, and with the same economy in verticai space. Y

I claim as my inventioni V The combination and arrangement of the truck C 'and lioisting'and 'conveying tacklewith each other and with the track-'way A A, provided with head-blocks BB', and automatic(logging-hooks m, said tackle being either provided or not with the cams 'i and bulb b, and the several. parts constructed, arranged, erected, and opera-ted substantially as. and for the ppi-poses set (LHARlZlES A.
