T all whom it nmyoncern: v

Be it known that I, MELVlN A. YEAKLEY, a citizen of the United States, rcsiding at Litchfield, in the county of Medinn and State of Ohio, have invented certain new and useful lniprovenicuts in Hay-Slackers; nnd I do 1iercby declurc that the following is (t full, clear, and cxact description of the invention, which will enable others sltilled in the nrt to which ro it appertnins to make and use the same.

The invention relates to iinprovcnients in hay-stnclers; and the object of the inventiou is to provide zui appurutus which will take the hay directly from the wagon nnd dcliver it x5 where dcsired upon a stnck without the usual hand labor.

Tothis'en the invemtoir consists in i'staeking device eonstructed shown und described, and purticularl'y pointcd out in the elainis.

lu the acconipanying drnwings, Figure l is a perspective of the device on a grcntlyreduced scule, showing the position ol' the parts before being raiscd for work. Fig. 2 is u per` spective of the device after rnising and in rendiness for work. Fig'. 3 is ay central longitudinal section of the carricr. Figi -i is a transverse section of the carrier on iiue ;1: .'v, Flg. 3. Fig. 5 is a. yoke which cnguges the carrier and holds it while the hay-hook is ht'in'h`` loaded.

Fig. 6 in full lines is nn end elcvation of uportion of the apparntus in Vertical position and in dotted lines in ineliucd position to either side, according us the loud is to he carried to one side or the other of thestnck, Fig. 7 is n 55 side elevution, and Fig. S an cud elevntion, of

a windlass for Operating the ropcs which give the inclinutions shown in Fig. lis h, 10, and ll are details, hcreinafter fully cxpluined. Fig.'l2 is a view of the pulley-blook which 40 supports the carrier-enblcs at the right of the apparatus, us here shown, und connected to upper stnple or bolt on the right-hand pos-t in Flg. 2, or seen in miniature on the end of the cerrier-block in Fig. l. Fig. 13 showsthc eables or ropes with their pullcys and elaiups,

that are groupcd in the extreme left-'hand corner of Fig. 1, und through which the inclina' tions of the dcvicem'e client l lfig.` ltshows the detnils of u tenipornry cmnp 'oi the cords The ihvcni for stacking liny, end will (Nu model.)

ennble both the wagon and the stock to he comprised within its ends, as well as of such elo vat-ion that the device can bo operated to practlcally complete a Stack of the usual height. For this purposc l cuiploy cud posts orpoles, A B-say twenty-five feet liigli--plzieed about fifty feet apart. rllhe space from corner to corner lut-erally when stn'ked down is about fifcy feet. These dimcnsious will serve ns guides. They uiay be vuried more or less as larger or sniuller npparutus is desired. The poles A B are socketed to turn in shoes O, (shown in section, Figs. S and 11,) which are 'firnily staked to the grouud, and hnve guyrcpes or link-chains a b c for stcadying the poles in an upright position. The guys a preferahly ure :nude uflong'i'uetal links, which inny be folded -for eonvenience in handling and packing, and which will not stretch when drnwn taut. The guys b c are preferably part rope and part nietnl links, therope being used where they pass over the pulleys. These letter are connected, respective'ly, on opposite sides of the posts A near their top, at b' c', and pass over sheuvcs or pulleys W c`z at the staked-down corners 1 2 3 -L The two guys or cords Z) meet 'ut corner 4, and after passiug over their respective-,pullcys are brought together and run onto one Section of'the wiudln'ss E, while the cords c run to the same corner, und, passing over their put eys, uro united und carried round the other, section of the windhiss.

The windluss E is prcferubly attnehed by o. suituble fruine to the post A, eusily-reuiovable bolls beinfr cmployed for this purpose; but it inny he stnked iu the ground, if deslred. lt is foruicd with groovcs c, and its` respective ends tapet' toward the center, so us to enable more cord to be taken np o r paid out on one or the other of cords b c, us the posts A are inclined to one side or the other. As here shown, the windlnss has eogs e' at one end, which are engnged by cogs of a lercr, F, which is pivotcd on the frunie and serves to lock the windluss in any desircd position. A Crank und pinion, c'z ci, :irc eniploycd to turn the wiudlziss in cithcrdirection; but. n erunlr. mity 'ne npplled directly tothe wiudlnss and an' swer the snnie purpose, thongh. it' would net opernteso casi 'l; o nro ntt ehed to the wndiss to -t even one sent-ion their position.

Vandstill work perfectly.

'halfthereofl and the cords o to wind on the 0th er half, and they are so arranged that when one set winds up the other unwinds. This eonstitutes the mechanism for incliningthe posts-from one side to the'other, according as the hay needs to be deliverrd to one or the other side of the stack. I`n this operation I have found that when there is a swing of thetops of the polessay ten feet to one side-there is more slack to be taken up than there is rope to'be given out on the other, so the take-up rope will wind gradually on [hc inereasing diameter of the windlass at one end, while the payingout rope or cord will feed from a decreasing diameter on the other end. AWhen the posts are up'- right, both ropes or cords are held on the same diameter of wndlasssay midway of each end or section-and travel from that'point, one toward the end and the other toward the center, according as the posts are inclined to right or left of a Vertical position. This construction keeps the cords or guys always tight, so that the poles are [irinly slayed lat-erally, whatever llanips G- are shown on the cords b c at .corner 4, Fig. 13, and in detail in Fig. ll, which are placed on these cords to hold them taut before the ends thereof are attached to the windlass. This occurs when. the stacker is being set up. After the cnds of these cords are secured to the windlass and stretched the elam ps are i'emoved, thus leaving thevcord free to play over the pnlleys.

The next feature of the invcntion is the earrying device for carrying the hay from the wagon to the slaek.

lt will be obscrved that the post A has an arxn, A', pivoted lhereto at one end, while the upper end held by a suitable link to the top of the post. To this arm is altaehcd a yoke, G'. (Shown elearly in Fig. Sand in section in Fig. 3.) In the cnds of this yoke is a. crosspin, g, and to this pin are attached the cnds of the carrying-cablcs H. These cables are preferably two in number and consist of rope or other l'lcXiblc and yiclding material. lron rods lwould not scrve the purposc, as no frame of the eharactcr here described could hestak ed down to prevent the rods from bending under the heavy load they would be required to carry.

. Myinvention is therefore organized and de' vised With reference to the use of a flexible cable that may sway more or less under a load the cables pass over a sleeve or pulley, i, in

the block I, Fig'. 12, attached by a link, I', to

a hook at the top of the pole B. In operation this pulley lics horizontal, so thatlthe-t-wov tracks or parts of the cable will lie in the same horizontal plane their entire length.

K represeuts the hay'carrier. (Shown on a large scale in Figs. 3 and 4.) This carrier is 'designed to be automaticin much of itsaction. On either side of its main portioii are'secured two pulleys or shcaves, 7a, on which it travels over the cablcs II, the cahles passing through boxcs-whieh eonfine the At the opposite end' sheaves and the cables as well. Having placed the carrier on the cables, it requires two forces to give it the desired operation-moe to draw the carrier from over the wagon to a point over the Stack, and the other to carry it back over the wagon as it has discharged its load. The forward movement'is effected through a dra'ftrope, L, attached at Z to the carrier, and, passing beneath a pulley connected with the fork and over a fixed pulley, Z', on the carrier, runs over pulleys P Z o'n post B, and thcnce on t, to be drawn by horses, by which the fork-load of hay,usually from five to eight hundred weight, is conveyed from the wagon to the stack. The load then 'being discharged by an ordinary triprope, the draft-rope is released from the horses and the carrier is speedily returned to its position for loading by a counter-weight, M, connected by a cord, N, over a pulley, a, on standard A, with the rear of the carrier at af. (See Fig. 3.) The weight M has a pulley in its end, around which the cord N passes, and a guide-rope, N', extending from the top of post A to ground,l guides the weight up and down. Ifthc counter-weight is dispenscd with, the trip-rope will scrve to draw thecarricr back over the wagon.

In the earrier is mechanism, first, for locking the fork when it is drawn up to the carrier and everything is ready to convey the load over the staek, and, second, to lock the carrier on the yoke G' while the fork'is taking 'its load from the wagon. This mechanism is as follows: First, it will be observed, Fig. 3, that there is a bell-crank lever, O, pivoted at o, and provided with a hook or catch, o', at its lower extrcmity. The hay-hoolr has a rigid link-shapcd extension, P. (Shown in dotted lines, Fig. 3, and full lines, partly broken off, Fig. 4.) This link or loop, by reason of its position on the draft-ropc with reference to the point of attachment l and the sheave t' on the carrier, is always centered, soas to enter the Ashaped recess lt' in the bottoni of carrier K. (See both Figs. 3and 4.) A small bevcl-edgc pivotedguidc-blockJti, may be inserted directly beueath the hooked end of lever O, so as to direct the loop l? of the hay-linek lo the center if it Strikes beneath the said hooked end. Above the A-shaped recess lt' is an open space extending up through the center of the carrier, in which is located a push-bar, Q, connected at q with the upper arm of the bellcrank lever O and extending down through thclcarricr within reach of loop or link P, when said loop .is at the top of the A-shaped recess k', as scen in Figs. 3 and 4. Above this recess, and corresponding somewhat to the size of the end or loop or link P, is an angular recess, 703, Fig. 4, into which the bar Q projccts a short distance 'when down, and which forms a limit for the npward movementofsaid bar by means ofloop P, when the same is forccd upward by tensiou on the draft-rope. throws catch o' on the lcver O into engagement This upward movement` with loop P and looks the hayhook lfirmly to the carrier, ready to bear the load to its destinaticn.

At the upper left-hand corner of the carrier is an open slot, 10, having flaring projeetions 'or arms K5 K, and between these arms is a disk, S, having the recesses 8 s' cut in its periphery.v This 'meehanism, with the yokc G', serves to hold the carrierwhile the hay-book is taking its load. The looking' position of the parts is clearly shown in Fig; 3. rhen when the hook returns loaded, as before descrihed, and swings lcver into position, 'as shown in dotted lines, Fig. 3, the disk S will be released from engagement with lever O and the carricr set free to travelto the Stack; Then having gone to the Stack and discharged ifs load, as before described, the horses are detached, the countereweight r'nns the carrier back over the wagon, and the yoke is automatically engaged by the disk S. It will be observed thata wide :*h-u'i'n'g month is given to the carrier for the yoke G to enter, so thatit will not fail to make the engagement with its locking-disk, even though the carrying-cables be very slack-for example, as seen in Fig. 2. A pin, 8, on the back of the disk S, liinits the oscillaiion of the disk, striking in one position against the end of the upper arm of level' O and in the other against the carrier, as scen respectively in full and dotted lines, Fig. 3. It will be nndersteod, vof eourse, thahthese partsV will .bo

made on a large firm scale suited to the character of work they arel to perform, and the push-bar Q, being made, say, of iron to give it weight and moving freely in its bearings, will draw the lever into engagement with the disk S and lock it as soon as the yoke G' carries the disk around to the full-line position seen in Fig. 3. WVhen this occnrs, we have at the same time and by the same movemcnt of levcr O the release of the hay-book, which immediatel y descends to take its load. The foregoing operation is repca'ted when the hook retnrns loaded, and so on automatically until the wagon is 'unloaded ln Fig. 1 the apparatus is shown down and all staked out ready to be raised. rllhe windlass might bo attached at first and the guys st-retehed therefrom; but I find it more convenient to stretch the guys by hand and hold them temporarily by the clamps, seen in Figs. 13A and 14. If the posts are to bo, sny, twenty-fivc feet apart, the proper measuremcnt is taken from the left hand post, and just i so much cablc is paid out as will bring the carrier to the right-hand pole whenraised. \Vhen the apparntns raiscd, as seen in Fig;` 2, the cable-pulley block (shown in Figi. 12) rests against the head of' the carricr, and the ends of' the cnblc are fastencd to the yoke G'. as seen iir Fig. 5, by a peculiar knot, which enablcs me to pull on the end of' the rope and stretch it, while the knot is so fnrmed that a pull on the Cable will tighten it. .A similar tie is shown in Fig. 9, which shows how f eonnect the rope with metal links in 'the guys.

A draft'rope being attached to the carrier, as seen in Fig. 3, and being,F the only rope then extending to top end of pole B, the horses at' tached to the end of said ropefindicated by the arrow, Pig, 3,) will raise the poles to avertical position, pole l, being lightest in its equipments, will rise first and then pole A. This done, a man will ascendvpole B, on the pegs or link on the cable-head to the top of the post B, as shown connected in Fig. 2. The several guys, a b c, are then fnrthcr tightcned and the apparatus is ready for operation.

It is obvious that the operation herein described might he reversed, and the hay taken from a stack and delivered upon a wagon, and the carrying-cables might be stretched between two fixed points, or one fixed and one movable point.

If the ann on post A is dispensed with, the yoke that engages the oarrier should be set out from the said post about its present distance, so as to bring the carrier over the center of the wagon.

It should have been explained .that-when the disk S is released by the throwing up of the upper arm ot' lever O the disk is revolved to release the yoke G', and the disk tnrns under the said arm and serves to prevent the lower arm of the levcr O from swinging back and releasing its load. This release cannot thereforcl oceni' nntii the right timethat is, when the carrier is drawn back by the counterweight into engagement with the yol;e.,when said yoke, entering the flaring,` slot in the carrier, f'orcibly rerolves the disk and causes the upper arm of the r'arrier to drop again into its recess in the disk, thns relocking the parts and releasing the draft-hook from the lower arm of the levcr. W'hen thcparts arelocked, as seen in Figs. 2 and 3, the weight of the carrier and its load is praetically snspended from the yoke. I am thus enabled to operate with a compari'ttirely slack rope, which is impossible in any other form of carrier with which I am acquainted.
