sTaAw-sTAcKEa SPECIFICATION forming part of Letters Patent No. 385,634, dated July 3= 1888.

(No model.)

To aZZ whom it may concern,.-

Be it known that l, AUG'Us'r LAMMEDEE, of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Straw-Stackers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in whichl vFigure l is a central sectional side elevation of my improved straw-stacker, showing the carrier folded in full lines and extended in dotted lines. Fig. Z is a sectional view ofFig. l on the line ofshaft C. Fig. 3 is a detail plan view of the actuating mechanism, the carrier being` removed. Fig. 4 is a detail of the pit man connected to the gear.

This invention relates to improvements in straw or hay stacking machines; and its objects are to provide a machine in which the carrier mechanism can be set to deliver the straw to different points around the actuating mechanism, so as to enable the operator to builda stack without changing the position of the actuating` mechanism, to givethe carrier a certain predetermined vibrating movement, so as to deliver straw to different points of a stack, and to so construct the carrierframe that while it can be readily elevated as the stack is being built it will, when so lifted, be shifted backward, so thatitwill alwaysdeliver the straw approximately in the vertical line of the center of the stack. These objects are effected by my present invention, which consists in the novel construction and arrangement of parts hereinafter described,illustrated in the drawings, and concisely stated in the claims hereto appended.

Referring to the drawings by letter, A represents the supporting-frame of the stacker.

S is a transverse shaft properly journaled in frame A near one end thereof and having on its outer end at one side of said frame a drive-pulley, S, and on its inner end,which extends only to about the center of Width of frame A, a hevelgear, s', which meshes with a bevel-gear, s, on avertical shaft, C, which is properly supported and jonrnaled upon crossbars A4 of frame A, as shown.

E designates a spurvpiuion on shaft C above bevelgears s s', which meshes with a large horizontal gear-wheel, F, which is mounted on a short vertical shaft,f, properlyjournaled in cross-bars f* of frame A, to the inside of shaft C, and on shaftfabove the gear F is fixed a spur, G, which meshes with a large gear, H, that is mounted on a short vertical shaft. It, journaled in frame A similar to shaftf. The

gear H has aradial slot, 7L',in one ofits spokes,

in which is adjustably engaged the journalblock H of a wristpii1,H, as shown in Fig. 4, so that the wrist-pin can be readily adjusted on wheel H to vary the sweep or throw of a pitman, I, connected to pin H. This pitman extends forward tothe shaft Gand has formed on its front cnd,which is supported by a block, i, a rack, fi, which engages with a pinion, J, loosely mounted on shaft C and supported thereon above spur E by a collar, j, as shown.

Y designates a rectangular frame mounted above frame A. This frame Y is supported upon frame A so that it cau turn freely thereon by an annulns, K, which forms the base-plate of frame Y. This annulus K is supported upon friction rollers K, properly mounted in frame A.

K are retaining clips secured to frame A around the periphery of the annulus K, by which thc latter is held down upon its rol1- ers K.

Shaft C passes centrally through annulus K and has splined upon it within frame Y a bcvelgear, L, that meshes with a bevelgear, M, on a shaft, m, journaled in frame Y, and which shaft bears upon its outer end a pulley, N, hereinafter referred to. y

The annulus K has a series of perforations, lc, in it, as shown, concentric to shaft C.

z designates an arm rigidly secured to the hub of pinion J and standing above annulns K. This arm is provided with a spring-detent, z', which is adapted t0 be engaged with one of the perforations 7c in annnlns K, and thereby cause the Vframe Y to rotate with pinion J, as is evident.

Upon frameY is mounted the carrier proper. This carrier consists of a lower section, It, and an upper foldingor extension section, R', which is hinged at one end to the rear of section R, as shown. The section It hasjournaled in its IOO rear end the shaft p, carrying the usual carrier-belt pulleys, and the section it has in its free end a similar shaft and pulleys. Shaft p bears on one end, outside section R, the drivepulley P, which is driven by a belt, P, from pulley O on the end of a shaft, o, transversely journaled in frame Y, and which latter shaft is driven by means of a pulley, O, and belt o from pulley N, as shown. Section It is hung upon frame Y by means ofthe pairs of bars or rods T and V. Rod T is pivotally hungl hy .its lower end upon the shaft o, and its upper' end is similarly engaged upon shaft p. The bar W is pivoted atits rear end upon frame Y and extends backward to and is pivotally con nected with downwardlyprojecting portions or arms r of section lt. ln practice two pairs of bars. XV and T, are employed on opposite sides of the carrier. The bars W are longer than bars T, for a purpose hereinafter shown.

U designates an upright secured to the rear end of frame Y and rising above the carrier, as shown. Two of said uprights may be employed, if desired-one on each side of the carrier.

a; designates a rope or chain secured to the upper end of upright U, and, as is shown in Fig. 1, is passed thence downward and under bracket V, secured to section It near the front end thereof. Thus rope 00 passes forward to and around a pulley, w, secured to arm r of section R, the shaft of said pulley forming, if desired, the pvot attachment of the arms T thereto, and from said pulley w said rope x passes backward under bracket V, up over a pulley, a, in the upper end of upright U, and down to a drum, X, mounted on a shaft, X, properly journaled in frame Y outside of said upright, as shown. The shaft of said drum is provided with a crank by which it can be rotated.

In operation the carrier -sections are unfolded, and power is transmitted from shaft S through shafts C and m, by means of their geared connections, to pulley N, and from thence to the carrier-belt, as described. Motion is also transmit-ted to frame Y through the intermediate gearing from pinion E on shaft C to loose pulley J thereon, and from thence through arm z and its detent z to annulus K on said frame. It will be observed that pinion J is caused to alternately rotatein opposite directions as pitman I is reciprocated, and the amount of rotation-thereof is regulated by the distance of crank-pin H from the center of gear H. rl`he intermediate gearing between shaft C and pinion .Imakes the movement thereofsufficiently slow to vibrate frame Y slowly back and forth to an extent determined by the setting of crank-pin H. Frame Y can be turned to various angles relatively to frame A by disengaging the detent on arm z from annnlus K, and after setting the said frame at the proper angle can be vibrated by then engaging said detent with the proper opening /c of annulus K. It will be seen that the vibrations of the frame Y cause the carricr to swing slowly back and lorth, and that it is adapted to build a stack in the are of a circle having the shaft C as the center.

In building the stack it becomes necessary to raise the rear end of the carrier as the stack increases in height, and this is done by means of the rope x and drum X. As the rope x is tightened it draws section E slowly backward, and, o'wing to the differentpivotal points and lengths of bars T and WV, the bars XV will raise the rear of the carrier faster than the bars T will elevate the front end, and as the carrier is elevated it is necessarily drawn rearward, being supported by said bars. By reason of this construction the rear end of the carrier may-be always approximately vertically aboveV the center line of the stack, and it is impossible for it to be otherwise when the parts are properly adj usted to each other. This is a very important feature, for where the carrier turns horizontally on a fixed pivot its outer end is necessarilyretracted as it is elevated, causing the straw to fall toward the side of the stack nearest the machine. My invention overcomes this objection and dclivers the straw at all times, whether elevated or depressed, approximately over the center line of the stack, as is obvious.

I-Iaviug described my invention, I claim- 1. In a straw-stacker, the combination of the main frame, a vertical shaft, and a loose4 gearwheel on said shaft with the carrier mounted on said main frame, the arm secured to said gear-wheel provided with a detent adapted to adj ustably engage with an annulus supporting said carrier, the pitman engaging said gear-wheel and adapted to impart alternate rotary movements thereto, and the gearing for actuating said pitman from said shaft, all constructed and arranged substantially in the manner and for the purpose described.
