RUDOLF EIOKEMEYER, OF YONKERS, NEW YORK.

HARVESTING-IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 236,564, dated January 11, 1881.

Application filed September 9, 1879. y

To all whom it may concern Beit known that I, RUDOLF EICKEMEYER, of Yonkers, lestchester county, in the State of New York, have invented new and useful Improvements in Harvesting-Machines; and the following is a full, clear, and exact description of the same, reference being had to the accompanying` drawings, wherein- Figure l isaperspective View of my machine. Fig. 2 is a sectional side elevation of the same. Figs. 3, 4, 5, G, 7 are details in elevation, plan, and section.

This improvement relates to the. invention for which Letters Patent were issued to me 12th April, 1570, No. 101,719, and to WV. N. Vhiteley December 4, 1S77,No.197,916; and it consists, principally, in a triangular frame, a shoe, and a coupling-arm jointed to said shoe by a pin the axis whereof is substantially parallel to the line otl progression, and to said triangular frame by a pin `the axis whereof is oblique to said line; in connection therewith, a lifting-lever connected to said coupling-arm, whereby said coupling-arm may be rotated upon said diagonal pin; in a triangular frame, a shoe, and a coupling-arm with intermediate axis-pins, the one substantially parallel to and the other oblique to the line ot' progression, said axes intersecting at the pitman-joint; in a hinged shoe, a lifting-lever, and an interposed bail hinged to the shoe and provided with a curved slot to receive and contine a hook on said lifting-lever. Other points will be mentioned in the description and claims.

That others may fully understand my invention, I will particularly describe it.

For a detailed description ot' the structure and general operation ot' the devices included in this machine, excepting those devices hereinafter specially described and claimed, reference is hereby made to the patent last above named.

In the patent last above named, and referring to the letters of reference therein, there is a triangular frame, E, and at the forward end thereof there is a box, i, having' a longitudinal wed ge-shaped orifice, through which the coupling-bolt I passes, its ends being seated in lugs j k of the shoe G. This coupling` iits the box t' laterally, so that there can be little or no side shake, but is free to slide up and down at one end therein, actuated by the crank-lever L and coupling-rod o, as the points of the guards and cutters are tilted.

The method above described ot" constructing the connecting-joint between the shoe G and the triangular frame E has in practice certain defects, which I have avoided by the improved structure shown herein, and which I will now describe, referring to the annexed drawings.

Upon the under side of the triangular frame E there is secured a box, c, located in a horizontal plane when the shoe Gris upon the ground and. oblique to the machines line ot` progression. A pin, g, passes through this box and forms the axis of motion for a short couplingarm, H, which has at its extremity a similar box, h, Iand a coupling-pin, I, resting therein, its axis being parallel with the machines line of progression, and therefore oblique to the axis ot' the pin q. The shoe G is jointed to the pin I, as it is in the Amachine patented to W. N. Whiteley, above mentioned; but instead of producing` two independent motions upon onejoint-pin, as in that machine, I now have two independentjoints', one for each of said motions-that is to say, when the outer end ot' the cutting apparatus is raised or lowered its motion is about the axis of the pin I, but when the points ofthe lingers or guards are raised or lowered the motion is about the axis of the pin g. By this means the simplicity, cheapness, and durability of the joint are greatly enhanced.

ln the machine patented to NV. N. Whiteley above, the hand-lever is connected to the shoe G, at its rear edge, by means of a link or connecting-rod, M; but this rod acts upon one edge of the shoe only, and entirely behind the axis of the cutting apparatus, and it has afurther disadvantage in the unequal stress when thepoints of the guards are up or down. These disadvantages I avoid by providing a bail, B, the ends ot' which arejointed to the shoe Gr in front and rear of the tinger-bar, and hanging said bail upon a suitable hook, 7c, projecting from the extremity of the lever K. The latter will exert its stra-in uniformly in the same direction, and if the bail may slide over said hook as the front of the shoe is raised or lowered, the strain will be rendered practically uniform in all positions of the parts. This is a disideratum.

The bail B is preferably made with two sides IOO and a connecting arched part or top, the curvature whereof corresponds more or less exactly with the curve of motion which the shoe has when rotating upon the joiiit-pin g. This arched part rests over the hook 7a, and as the shoe is rocked upon the pin g the bail slides over the hook k. I prefer to construct the bail wholly or partly of cast metal and with the curved slot b, which engages with the hook 7c, and aside from increasing the strength of the bail, it enables the lever L' to push downward upon the shoe, as well as pull upward thereon. V

Having described my invention, what I claiin as new isl.y A triangular frame, E, and the shoe Gr of aharvesting-machine, combined with the coupling-arin H, which is jointed to said slice by a pin, I, the axis whereof is parallel with the line of the machines progression7 and to said triangular frame by a pin, g, the axis whereof is oblique to the line of progression, whereby said shoe and the cutting apparatus attached thereto may be rotated upon the pin I to raise the outer end of said cutting apparatus from the ground, or may be independently rotated upon the pin g to raise or depress the points ofthe fingers and cutters, substantially as set forth.

2. A triangular frame, E, shoe G, and the connecting` coupling-arm H, as described, conibined with the lifting-leverL and coupling-rod O, connecting the crank end of said lever with the coupling-arm H, whereby said couplingarin may be rotated upon the pin g, substantially as set forth.

3. The shoe G, connected with the frame of the machine bya longitudinaljoint-pin, I, coin; bined with the bail B, the end whereof isjointed to said shoe in front and rear of the cutterbar, and the lever K, provided with the hook k, wherewith said bail is engaged and whereby said shoe is caused to rotate upon said jointpin I, substantially as set forth.

4. A slice, Gr, connecting with the frame of the machine by a coupling-arm, H, one joint whereof is in the line of the machines progression and the other joint oblique thereto, so that the cutting apparatus attached to said shoe may be raised or lowered at its outer end or raised or lowered at the point ofthe fingers and cutters, and the lifting-lever K, provided with the hook 7,', combined with the bail B, constructed with a longitudinal curved slot, D, to receive and confine said hook 7.', whereby said shoe may be rotated upon its oblique axis while being supported wholly or partly above the ground by the lever K, substantially' as set forth.

5. The inner shoe of a harvesting-machine hinged to one side of a brace or arm, which arm in turn is hinged to one end of a vibrating frame by a hinge diagonal to the shoehinge and bisecting the axis thereof at or near the ptman-joint at the heel of the cutter-bar, substantially as and for the purpose set forth.
