SPECIFICATION forming part of Letters Patent No. 352,930, dated November 23, 1886.

. Application filed January 16, 1886. Serial No. 188,785. (No model.)

To all whom it may concern.-

Be it known that 1, ANDREW B. MOUOK, a citizen of the United States, residing at Fargo, in the county of Cass and Territory of Dakota, have invented certain new and useful Improvements in Butt-Adj usters for manual-- vesters, which are fully described in the following specification.

In the drawings, Figure 1 isa front elevation of part of a harvester-frame and drive-wheel, showing my butt-adjuster inposition thereon. Fig. 2 is a plan of my adjuster. Fig. 3 is avertical section of the outermost or lowest adjusting-bat, its crank-shaft, and lower bearing. Fig. 4is an elevation of the innermost. or upper adjusting-bat, its crank-shaft, bevel-gear, and upper bearing, and pitman-bar. Fig. 5

is an elevation of one of the intermediate'ad-- justing-bats, crank-shaft, and pitman -bar, which actuatesit. Fig. 6 is a plan, and Fig. 7 is an elevation, of a modified form of bat. Fig. Sis a section through xx, Fig. 1. Fig. 9 is a perspective of a cranked shaft which actuates the bats' A is the front side board of the elevatorframe of a harvester A is the outer brace for the same.

A is the binder-deck.

B is a bracket secured to the elevator-frame by the bolts 6 b, which pass through it and through said brace A and side board, A.

O is the shaft of the upper roller of the undownward and outward to afford asupport for the bearing, hereinafter'described, of the upper end of said crank-shaft. l

D is a bevel'gear on the lower end of said crank-shaft, meshing with and driven by the bevel-gear O.

' B is a plank or. base board pivoted on the arm B of the bracket B, and extending in the this plank, and constitutes the pivot for the same.

B an upper bar, securedto the'base board B by the crossbars B B B and having secured to it the bracket or lug 12 which affords the means for pivoting it on the shaft D, under the overhanging arm Bof the bracket B. This upper bar, B, has a bearing for the crank-shaft D, and for all the other crank-shafts hereinafter mentioned-viz. the lower or outer crankshaft, E, and the intermediate crankshafts, F

' F F, of which there may be any desired number. The shaft D, at the upper end, has two cranks, d and (1 the latter above the-former,

and in axial planes at right angles, or approximately so, their wrists D D being equidistant from the axis of the shaft D. The shaft E is similarly provided with the two cranks e and 6 having the wrists E -E precisely similar to the correspondingly-lettered parts of the shaft equal length. The intermediate crank-shafts,

F F F, have the cranks F at their upper ends above their bearings in the bar B*, and the wristsfff of said cranks are journaled in the lower link,G,at such points that the said cranks F F F all stand parallel with the lowercranks, e and d of the'lower and upper crankshafts, E and D.

To all the shaftsD E F F F are secured any desired number of butters or butt-adjusting bats H. Figs. 2, 4, and 5 show them with but two opposite bats. Figs. 6 and 7 show a form having four bats.

The operation of this device is as follows:

The crank-shaft D, receiving rotary motion by means of the gear 0, driving'the gear D on 0 said shaft D, revolves the bats H, secured to it, and causes saidbats to operate on the butts of-thegrain in the desired manner. The link G communicates a like rotary motion by means of the several cranks e and f f f to theshafts 9 5 E F FF, and so imparts a like butting action to the bats H, secured to said shafts, respectively. The link G, connecting the cranks d and 6 prevents the reversing of the rotary motion, or the tendency to reverse the same, I00 in communicating it to the shaft E. Such reversal would be possible when only the shafts E and F are employed, or if only one intermediate butter were employed, and the Wrist necting-links, as described, whenever one of.

them is over the center and might reverse the motion of the lower shaft the other is at one side and can transmit the rotary motion only in one direction, and therefore prevents the otherwise possible opposite motion derivable from the other crank.

The entire device has the shaft D for'apivot, and may swing on said pivot without destroying or impairing the connection with the driving-power through the bevel-gears G and D. Any of the familiar means may be employed for effecting adjustment of the device about said pivot and for securing it in any desired position.

I claim- 1,. In combination, substantially as hereinbefore set forth, the butter-frame, two crankshafts journaled therein having each two cranks not in the same plane, the link connecting the wrists of the cranks, respectively, nearest to the shaft-bearing, the cra'nkshafts journaled in the frame having single cranks whose wrists are journaled in said link, and the second link connecting the outer crankwrists of the two double-cranked shafts, and the train for revolving one of the doublecranked shafts, and the bats on all said shafts.

2. In combination, substantially as set forth. theelevator, and the bracket secured at the upper end thereof, the roller-shaft, and the gear thereon, the double-cranked shaft at right angles with the roller-shaft, and the gear thereon driven by the first-named gear, the frame pivoted on said double-cranked shaft, the second double-cranked shaft and the single crank-shaft journaled in said .frame, the bats on said shafts and the link connecting the inner cranks on all the shafts, and the link connecting the outer cranks of the doiiblecranked shafts.

In testimony whereof I have hereunto set my hand, in the presence of two witnesses, at Fargo, Dakota Territory, this 12th day of De- 'cember, A. D. 1885.

ANDREW B. MOUCK.
