BUTT-ADJUSTER FO-R SELF-BINDING HARVESTERS,

srncrrrca'rron forming art of Letters Patent No. 605,388, dated June '7, 1898.

Applicationfiled Jnne Zl, 1897.-

To all whom it may concern: 7

Be it known that I, WILLIAM BUTTERFIELD, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements inv Butt-Adjusters for Self-Bindin g Harvesters, of which the following is a full description, reference being had to the accompanying drawings, in which Figure 1 is a front elevation of as much of a self-binding harvester as is necessary to illustrate myinvention. Fig. 2 is a plan view with the grain-cover indicated by a dotted line. Fig. 3 is a sectional elevation on the line 3 3 of Fig. 1.

The butt-adjusting mechanism is located along the front edge of the binder-table B, as usual, between the elevator O and the binderframe D, and serves to hasten the butts of the grain down the table to their final position thereon.

E is the grain-cover at the upper end of the elevator. The elevator has the usual canvases e and 6'.

A is the adju'ster-bracket, in which is j ournaled the adjuster crank-shaft a, preferably adapted to receive rotation from the lower elevator-roller by means of the bevel-gears'e? and c At its upper end is formed a double crank a In the said bracket is also preferably pivoted a radius-rod A. Hung upon wrists on the double crank are butt-adjusting boards A and A by means of suitable arms a and (L The lower ends of the boards are supported by radius-links a. and a, said links being pivoted upon the swinging end of the radius-rod A and the boards being pivoted conveniently thereto by any suitable 1neans,those shown being brackets riveted thereto. Conveniently to the radius-rod is pivoted the usual adj uster-lever F, extending diagonally back to the top of the elevator within convenient reach of the driver and provided with the usual means for holding it in any given position of adjustment. The double cranks are substantially on opposite sides of the shaft a, so that one of the boards is acting upon the grain aggressively when the other is makiri g a return movement preparatory to a succeeding aggressive movement. As is well known, in some conditions of grain there is a tendency for the upper ele- Serial No. Mlfldl. (N0 model.)

v'ator-canvas to carry bunches of straw back between'it-self and the grain-cover and choke the elevator. Siniilarly'the lower elevatorcanvas sometimes carries straws down between itself and the upper edge of the binding-table. The upper board can be of such length as to approach'very close to the upper elevator roller and the space thereabove where the straws sometimes choke, so as to positively take the grain away from the same without allowing it to be carried over. For that purpose its end nearest the roller is provided with an aggressive toothed slat co The lower board, hung upon the lower crank, while having preferably the same throw as the upper one, can be proportioned difierently, so

as to take the grainfrom the lower elevatorroller before it is permitted to be carried downward below the table. It also has a claw or aggressive toothed slat at its upper end. Both boards are provided with the usual aggressiveslats a along their length to aid in positively carrying-the grain down.

To the adjoining edges of the adj usterboards are attached plates a and a, extending toward the front of the machine, the purpose of which is to prevent straws from getting between the boards as they move intheir orbital paths.

i It is foundin; practice that the action of my'up'per board uponthe upper portion of themass of grain confined between the deck and grain-cover tends to move the portion that lies below. "For instance, if the board A 'alone wereused the whole mass of grain would be moved in the direction of the binding receptacle proper, the action of the board A would carry all straws with which it came in contact, and the agitation and for- 0 ward movement of those would so inflluenee all the straws beneath as to cause them to move down the table. In other words, the mass of straws being free to move and partially influenced by gravity, movement of the 5 upper stratum would carry the lower stratum therewith to a very great extent. Theconverse is true-that if the lower one of the two boards only were used the straws with which it came in contact would be moved deliveryward and the straws above would also be influenced to move in the same direction.

The cooperation of the two boards is such as to not only move the straws endwise for adjusting them so as to be centrally bound, but to in effect have two feeding-strokes down.- ward to every revolution of the crank-shaft carrying them. This double action is found in practice to be a very material benefit.

I am aware that butt-adjusters have been made consisting of a series of toothed bars moved by cranks and adapted to be thrust through slots in the frame guiding them, in which case there was no means for producing a beating effect upon the butts of the entire mass of grain in the receptacle;'but only teeth that at various horizons, as it were, above the binder-table should dig into the mass, and thus feed it by clawing actions. While this clawing action tends to Work the grain down, it does not do so in a satisfactory vented by the alternate strokes of the two parts, one acting upon the butt of the gavel while the other is making its return movement.

I claim- 1. The combination with the elevators the binding-table and the grain-cover, of a grainadjusting device consisting of a plurality of orbitally-moved boards arranged one above the other and adapted to move in close relation to each otherand also adapted to act alternately, and thus engage the butts of the straws in the receptacle, move them endwise and advance them deliveryward, each of said boards having a plate attached to the edge adjoining its fellow board, substantially as described. I

2. The combination with the elevators, the. binding-table, and the grain-cover, of a grainadjusting device consisting wholly of two orbitallymoving boards placed edgewise in close proximity to each other, the plane of saidboards being substantially perpendicular to the binding-table, and said boards being operated so as to act alternately upon the butts of the straw upon the table, to simultaneously move the same endwise and sidewise,whereby only one portion of the adjuster is active upon the grain at a time, the other portion being meanwhile out of action, substantially as described.

3. The combination with the elevating-conveyers, the binding-table,and the grain-cover, of a grain-adj usting device consisting wholly of orbitally-moving boards placed edgewise in close proximity to one another, the plane of said boards being substantially perpendicular to the binder-table, and said boards being operated so that, although the entire face of the adjuster is constantlyin motion, the individual boards of which it is composed act alternately upon the butts of the straw upon the table to simultaneously move the same endwise and sidewise, substantially as described.

4. In a grain-binding harvester, the combination with the receiving-table, the graincover, and the upper and lower elevating-conveyors, of a grain-adj usting device composed wholly of a plurality of orbitallymoving boards, one placed immediately above the other, the lower board located and adapted to sweep in close contact with the table, and the upper board located and adapted to sweep across the plane of the lower conve-yer toward and near the end of the upper conveyor in close contact ,with the cover, and the two boards thus cooperating to clear the space between the roller of the upper conveyer and the overhead cover and between the roller of the lower conveyer and the edge of the receiving-table, substantially as described.

5. In a grain-binding harvester the combination with the binder receivingtable, graincover and upper and lower elevating-conveyers, of a grain-adjusting device composed of two orbitally-moving boards, one above the other, the lower one adapted to clear the space between the grain-receiving table and the lower conveyor-roller, and the upper one to keep clear the space between the upper elevator-roller and the grain-cover, and plates attached to the adjoining edges of said boards and projecting outwardly and adapted to prevent straws from getting between said boards, substantially as described.
