SILAS H. WILSON, OF AUBURN, NEW YORK, ASSIGNOR TO WM. H. BROWN, OF SAME PLAGE.
IMPROVEMENT IN PITMAN-HEADS FOR HARVESTERS,&G.
Specification forming part of Letters Patent No. 55,435, dated June 5, 1866.
To all whom it may concern.'
Be it known that l, SILAs H. WILsoN, of Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Pitman-Heads for Harvesting and other Machines; and I do herebydeclare the following to be a full, clear, and exact description otl the same, reference being had to the accompanyingdrawings, making a part ot' this specication, in which- Figure l represents a side view ot'l a pitmanrod. wrist-pin, and their connection, forming a pitman-head-and oil-cup. Fig. 2 represents a longitudinal section through the same. Fig. 3 represents a vertical transverse section through the box and oil-cup, the wrist-pin being left in full. Fig. 4 represents the box as removed from the pitman-head, and showing the oblong' recess in it for giving it one of its yielding motions.
Similar letters of reference, where they occur in the several separate figures, denote like parts ofthe contrivance in all the drawings.
My invention consists in so constructing a pitlnan-head as that the pitman-rod and wristpin may have triplicate motions to allow them to yield to the many varied rising and falling motions incident to a harvesting-machine in its operations in the field, and thus prevent cramping, binding, wearing, and clatter.
To enable others skilled in the art to lnake and use my invention, I will proceed to describe the same with reference to the drawings.
A represents an oil-cup, to which the pitman-rod B is screwed, there being a jamnut, O, on said screw to hold the cup and rod at the adjusted position when so adjusted.
In the opposite end of the cup from the pitman there is a screwpivot, D, which may be turned by its head E, and ajam-nut, F, is arranged on the screw to hold it tirmly in its adjusted position.
Within the oil-cup A, and supported by the screw B at one side and by the pivot D at the opposite side, is a box, G, divided, as at a, or in one piece, as may be preferred. Where the screw B (which is the end of the pitman-rod) rests against the box Gthere is formed an oblong recess, b, as seen in Figs. 2 and 4, into which the point of the screw enters. On the opposite side of the box, where the pivot D enters, the recess c may be conical or hemispherical, the pivot being ot' a corresponding form. Through this boX G the wrist-pin H passes, and is connected to the crank-wheel and has end motion or play in said box, as seen by the space c, between its head d and the bottom of the oil-cup, through which space it can move.
By means of the oblong' recess Z) in the box G the crank-pin H and box may rock or roll in the direction of the dotted lines x x, and they can also move upon the pivots B D, so that the pitman and crank-pin have three distinct motions with or independent of each other-viz., tirst, in the line of the length ot' the crank-wrist; second, by means ot" the oblong recess they can move one or both in the direction of the lines .rg and, third, they can rock or roll on the pivots B l). If either the pitman or crank-wrist should tend to bind or cramp by the raising or lowering ot' the cutterbar, or by the raising or lowering ofthe main frame, one or the other, or all three, of these yielding motions will admit of any of the positions they could assume, and Astill work free without friction or binding.
Oil-openings l 2 3 may be made in the box G, to communicate with the supply in the cup A, and thus keep the parts lubricated. It',v
there be any wear between the parts, which causes unpleasant clatter and noise, the screwpivot may be run up, the jam-nuts reset, and the whole will again work noiselessly.
Having thus fully described my invention, what I claim therein as new, and desire to secure by Letters Patent, is
So combining and uniting the crank-wrist and pitman ot' a harvesting or other machine, through a box and oil-cup, as to admit of a triplicate motion between the wrist and pitman, to prevent all binding or cramping, as also clatter, between the parts, substantially as described.
SILAS H. WILSON.
