To' all whom, t may concern.'A

-Be it known that I, GHARLEs E. MERRL FIELD, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Straw-Stacking Machines, of which'the following is aspecifcation: n My'invention relates to improvements in straw-stacking machines in which the straw is received uponan endless-apron carrier supported and operated on a turn-table or bolster mounted on a truck. i

In the accompanying drawings, Figure l is a3 side'view of my improved straw-stacker; Fig. 2, a rear view of the same, showing one of the braces to rear axle in section, Fig. 3, a horizontal section on line x as on Fig. 1'; Fig.` 4, a longitudinal vertical section, on a larger scale, through the machine on line z z on Fig. 3; Fig. 5, a vertical cross-section von line y y on Fig. 4.

The same letters refer to the same'or correspondingy parts throughout the several views.

' rIhe bolster B, to ywhich'the supports of the with thesingle truss-rod 15'..V Said rod l. runsl to and engages into an eye, m, formed by the rods t2 ith-immediately underthe pivotfpoint of the bolster B. 4 The rods t t2, beingsecurely bolted to a cross-beam, a, andlrun from there to the'cross-beam a', secured to the rear part of the carrier-truck A, or to the sides of said truck, form, in connection with the rods't tand the rod t', a strong truss, and-prevent the weight of the carrier L'breakingl or twisting the king-bolt on which the bolster B operates, while the eye m, being right under the center of said-king-bolt, allows the upper parts of i' theV truss to swing around with the carrier.

. Tothe -bolstenB .are rigidly secured thestandards S S,"also the'frame-work @which` supports the shaft D, on whichy the ropes E E,

0 th at raise and lower the hoisting-wheels WV YV and the stacker-frameL, are wound and unwound by means of a worm-gear consisting of the spirally-toothed wheel d, secured to said shaft D, -and operated by the endless screw d on the end of the shaft di. Said shaft d2 is operated by the crank d3 at the front end of the bolster B. By turning the crank di the stacker `thetop of the vboxing G the sleeve J operates,

which is provided with a bracket, j.

. 'The spindle I operatesjin.` the boxing G,

which boxing at the same time forms a' kingbolt for the bolsterB. 4

lThe bevel-gearing on the shafts P and P are held intheir proper position with the gearwheels on the spindle Iby thebracket Nl and the sleeve-bracket J j, while the gimbal-joints O and O in said shafts l? and P prevent the gearing from being thrown out of its proper position by the unavoidable rocking of the bolster B. These' gimbal-jointsadmit of such rocking and allow of Vthe shafting being bent. To the hoisting-wheels .NV YV, which are bolted to the sides of the stackereframe L, are secured the` ropes EE, through the set-screws ce, said set-screws allowing the ropes'beingV adjusted', whenever needed, without stopping the machine and losing valuable time.

ToA strengthen the stacker-frame L, the braces KK are inserted into the sockets k lr, secured to the wheels WWand into the sockets ZZ on under side of the stacker-frame L,

near the folding-point of said frame'i.

Bolted to each side' ofthe axles of the truck end of the braces B R, when the machine is set up for operation; Said braces B B are shoved through the wheels of the truck A--up into the clevises or sockets ro, and by'means.

.of the blocks 1^ 9', 'driven. between the' braces R R andthe axles of' the truck A,'the'truck` is rigidly braced, and any tipping over of the roo saine when the stacker swings around prevented.

A belt from the engine or thrashing-machine drives the pulley on the outer end ofthe shaft I. The bevel-gear on the inner end of said shaft operates the spindle I in the boxing G. The spindle I operates the shaft P by bevelgearing, and the pulley on the outer end of the shaft P operates the stacker-shaft. The following are the new points in this mechanism: the brackets N N at the lower end of the boxing G hold the lower bevelgear together, while the sleeve J, with the bracket j on the upper end of the boxing G, holds the upper bevel-gear in place and allows the swinging around of said gear in connection with the bolster B, and admits of the rocking of said bolster B without separating the gear.

By the use of the gimbal-joints O and O in the horizontal shafting I and P', the power can b received in the center of the standards that support the stacker-frame, and carried forward to thc boxing G, which is placed in front of said standards S S; and then above thebolster B the power can be carried back again to the center of the standards. This is anadvantage over the usual method, where the pivot-point of the bolster and the gearing is placed in the center of the main supports of the carrier, whereby the carrier cannot be swung around at right angles or moved toward the machine without interfering with thev gearing and bracing, while my method of placing the pivot-point of the bolster and the gearing forwa'rd of the center of the main supports, and of using gimbal-jointsin the shafting, enables me to swing the stacker around at a greater angle and to build a larger stack.
