UNITED STATES PATENT OEEICE.
OYRENUS WHEELER, JR., OF AUBURN, NEW YORK.
IMPROVEMENT IN PITMAN-CONNECTIONS FOR HARVESTERS.
Specication forming part of Letters Patent No. 74,463, dated February 11, 1868.
Crank Rod Connections for Harvesting-Machines and other purposes; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specication, in which- Figure l represents a vertical, and Fig. 2 a horizontal, section through the wrist-connection, and showing its capabilities of yielding or accommodating itself to the changing positions of the crank-wrist and the in strument driven by it through a connectingrod.
Similar letters of reference, where they occur in the separate gures, denote like parts in both of the drawings.
My invention relates to the manner of coinbining the wrist-box and the pitman with the pitman-head, so that each may have motions with, as well as independent of, said head, by which means the pitman may accommodate itself to the many changing positions of a harvesting-machine cutting apparatus without binding or cramping.
To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawings.
The portion A of the wrist-box frame may be cast, and has an opening through it for the pitman or connecting rod B,.anda recess for catching and holding the head O of said piti man or connecting rod, and so arranged that said piece A can freely turn on and around said rod as a center. Upon the end of the piece or portion A there is a plate, a, which prevents the pitman B from moving endwise through it 5 and there is also, upon the opposite face of this plate, a curved recess, b, against which a curved projection, c, on the wrist or crank box D rests and can move.
Diametrically opposite the projection c on the wrist-box there is a similar curved projection, d, that ts into and moves upon a curved recess, e, in a plate or head, E, and the two pieces or heads A E are held together by the bolts F F and nuts ff, and hold between them in two parts, as shown at t, and has flanges j 'm lapping over the joint, and an oil-hole, o.
This whole contrivance may be termed a crank-head, which has three movementsviz., one with the wrist or crank on which itis placed, a second motion on the curved surfaces b c and d e, and a third one around the pitman or connecting rod, and thus it onforms to all the twisting or cramping or binding motions that may occur between a cutting apparatus which is raised, lowered, and turned at one end of the connecting-rod, and a crankwrist at the other end thereof. j
F is the crank-wheel, to which the crank head or frame may be connected, the portion F being solid to steady its motion, the other portion cast hollow. The pitman-rod, having the crank head or frame connected at one of its ends, is pivoted by its other end to amalleable cast-iron head that is fastened to the knife-bar or knives.
Having thus fully described my invention, what I claim is- In combination with a crank or pitman head that can turn on or around the pitman, a Wrist-box that turns in said head by means of its curved surfaces c o moving against the concave bearings in the plates b e, substantially as and for the purpose herein described.
