HARVESTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 247,182, dated September 20, 1881. Application filed August 5, 1881. (No model.)

To all whom it may concern:

Be it known that I, DAVIS W. EN'LRIKIN, of Kennett Square, in the county of Chester and State of Pennsylvania, have invented certain new and useful Improvements in Harvesting- Machines, of which the following is a specification.

This invention relates to that class of harvestin g-machines wherein the cut grain is received upon a moving endless apron, and is thereby conveyed sidewise across the machine and delivered to the elevator, which discharges it in suitable condition to be bound, either by hand or automatically.

when the grain to he cut stands vertically in the field there is no difiiculty in' cutting it with harvesters of this class butit very often happensthat heavy grain is quite tangled, with theheadsinclined invariousdirections. Then this grain is cut it advances up the elevator in a tangled mass that often chokes it, arrests the mechanism, and breaks parts thereof.

The operation of carrying grain in good order up the elevator is particularly diflicult when the grain is inclined in the path of the machine with the headsthereof toward the elevator. Alter such grain is out it will generally remain for a while leaning against the elevator, with its butts upon the conveyor, preventing the entrance of the grain following into the elevator, and when it finally entersit is in a confused mass.

The object of my invention is to produce means to cause grain, the heads of which may be leaning toward the elevating-aprons, to fall immediately after bein g cut close to the entrance between said aprons and parallel with the axis of the rollers supporting said aprons.

Heretofore various means have been used to overcome the difficulty. guiding wires placed above the lower elevating-apron have been secured to rollers, have been madeto pass around rollers and extended up again to the drivers foot-board, or have been screwed into boards set nearly parallel with the elevating-apron, but they do notfully answer the purpose intended. As the heads of the grain have a tendency to enter the elevator before the butts, various means have been used to advance and elevate the butts of the grain, either by means of reciprocating racks, or by means of a crank-operated lever The compressing and having its lower end forked and intended to forcibly lift the butts of the grain in a plane oblique to the plane of the elevator, but only in advance of a plane passing through the frontor finger bar of the machine, as shown in Patent No. 239,004,0t' 15th March, 1881. NVhilein my construction the operating-lever moves entirely in the rear of the finger-bar and over the center of the conveyer, it does not act at all upon the butts of the grain, but upon the upper portion or heads thereof, retarding their advance and straightening them parallel with the axis of the rolls carrying the aprons.

The invention consists in combining with the conveyer, the elevator, and the foot-board of a harvester, a pulley mounted upon said foot-board and carrying a crank-pin, andaslotted lever, connected to operate over the. conveyer upon the heads or upper portion of grainstalks, and straighten them parallel together.

Itconsists, also, in combining with theframe of the harvester a fender or deflecting-board pivoted thereto and a spring-catch for said fender, as will be hereinafter more fully described in connection with the drawings, and then pointed out in the claims.

In the drawings, Figure 1 represents a perspective view of a harvester-frame to which my invention is attached. Fig. 2 is a longitudinal vertical section of that end of theframe having the grain-elevating aprons. Fig. 3 is a transverse vertical section of the frame, showing a side view of the invention. Fig. 4 represents a perspective view of the fender or deflecting-board. Fig. 5 is a perspective view of the fender-retaining catch.

In said drawings, A represents the front or finger bar of the machine, and A the rear bar. At the inner end of the machine the elevatorframe A is placed to carry, as usual, the rolls 1) b and c 0, around which are stretched the elevating-aprons B and G 3 and the horizontal conveyer D is also mounted upon rolls d, to which motion can be given in any convenient manner. E represents the dividing-board, and F the drivers foot-board, upon the rear end of which the drivers seat is generally placed.

The above-mentioned parts are in common use.

A portion of my invention relates to the following means to cause grain that would otherwise remain for a time leaning against the elevating-aprons to fall promptly across the conveyer adjoining to the entrance of the elevator.

To the elevator-frame A is pivoted, preferably by its lower corners, g, the fender or deflecting-board G. This fender I prefer to make of a light board of suitable width, and about as long as the width of the elevating apron, butit maybe madeof sheet metal, orof a frame covered with canvas.

The face or upper edge of the fender is retained at any desired inclination by means of a spin g-catch, H, secured at one end to the elevator-frame A and provided at the other end with a series of teeth or projections, h, between two of which the end of the fender will enter and be retained, the catch being so sprung and secured to the frame as to continuously bear against the fender.

The lower edge of the fender is set above the periphery of the roller of the upper elevator-apron, (if an apron is used,) or above the guide-wires retaining-board, if such wires are used in place of the upper apron, and said fender is generally set about perpendicular to the face of the elevator, its upper edge overhanging the conveyer, so that any grain leaning against said fender (while the reel of the machine continues to bend grain over the conveyer) will promptly fall upon said conveyer sufficiently in advance of the entrance of the elevator to have the stalks parallel with the axis of the elevator-rollers before entering between them.

To further facilitate the untangling and straightening of grain -stalks after they have fallen upon the conveyer, a movable lever, I, is provided above said conveyer, and so suspended and operated that its lower extremity will describe an arc of an ellipse over the conveyer and engage at the lowest point of its course with the grain-stalks, as near as possible in the middle of their length, or between it and their heads, the leversupport being for that purpose adjustable upon the foot-board F. This support consists of a frame or standard, J, having on one side of its upper end a projection, J, made to extend over the pulley K, giving motion to the lever I. The upper end of'this lever is retained connected to the projection J of the standard by a washer placed under the head of the screwj, passing through a longitudinal slot, z, in the lever, and screwed into, or bolted to, the projection J of the standard.

The pulley K is pivoted to the standard so as to turn freely under the projection J. It carries a headed crank-pin, 70, that passes through the lever I, and (in connection with the screw j in the slot 6) causes its lower end to describe a long flat curve over the conveyer, and among the stalks of grain that may be upon said conveyer. Motion may be transmitted to the pulley K by means of a belt or chain from the pulley L upon the reel-shaft Z, or from any other movable shaft of the machine.

Having now fully described my invention, I claim- 1. The combination of the conveyer, the elevator, and the elevator-frame of a harvester with a deflecting-board, G, pivoted to said frame, and adapted to be inclined and set at any desired angle over the conveyer, substantially as and for the purpose described.

2. The combination of the conveyer, the elevator, and the elevator-frame of a harvester with a deflecting-board, Gr, pivoted to said frame, and a spring-catch, H, substantially as and for the purpose described.

3. The combination of the conveyer, the elevator, elevator-frame, and foot-board of a har vester with a standard upon said foot-board, pulley K, pivoted thereto and provided with a crank-pin, and slotted lever I, connected with said crank-pin and with the top of the standard, substantially as and for the purpose described.

4. The combination of the conveyer, the elevator, elevator-frame, and foot-board of a harvester with a standard or frame upon said footboard, a crank-pin, and a slotted lever having its lower end adapted to sweep in the rear of the finger-bar, over the conveyer and in front of the elevator, substantially as and for the purpose described.
