naar. sara f ,HIRAM L. WANZER, 0F LANESVILLE, CONNECTICUT.
Letters Patent No. 96,643, dated November 9, 1869.A
IMPROVEMENT IN CRANKS lFOR HARVESTERS.
The Schedule referred to in these Letters -Patent and makngvpart of the same.
To all whom it may concern Be it known that I, HIRAM- L. WANZER, of Lanesville, in the county of L itcheld, and State of Connecticut, have invented a new and. improved Crank for Harvesters and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in .the art to make and use' the same, reference being had to the accompanying drawing, forming part of this specification,
The object of this invention is to furnislrmeans for varying the velocity of the cutters of harvester-s, to accommodate the machine to the nature of the work audspeed of the team, `and also to compensate for the wearing away of the knives by grinding.
The invention relates to certain improvements on the crank-pin connection described in the specification of Letters Patent granted to the petitioner, July2, 1867", and reissued November l2, 1867.
By means of the present invention, the devicerefer-red to can be more easily constructed, is less liable to get out of order, and can be more readily applied to machines already in use.
The crank-'pin can be adjusted to dierent strokes without removing the pitman. kIn the annexed drawing, myI invention is illustratedl Figure 1 being a face View of the pitman-wheel.
Figure 2, a horizontal section ofthe same, showing the crank-pin.
Similar letters of reference indicate corresponding The crank or pitman-wheel A is hung and ope-rated in the usual manner.' It is connected with the pitman by a pin, C, which is' shown more particularly in lig. 2.
- That port-ion ofthe pin C which passes through the wheel is of peculiar forni, it being conical at the outer end, cylindrical in the middle, and provided with a screw-thread at the inner end. It is so placed in the crank or wheel A, that by drawing the nut a, which screws over the inner end of the pin, the pin may be held secure in the wheel.
The outer end of the pin Gis of smaller diameter than that part which is in the crank, 4and isset eccentrically nponthe same, as shown in g..2. Y The pitinan is 'pivoted to the eccentric portion of the pin.
The cylindrical portion c of that part of the pin which passes through `the crank is provided with holes or indentations, of va conical or other suitable shape, so that, by means of a set-screw, d, fitting' with the endv into one of-said holes or indentations,'the pin may be secured in any suitable position.
The extremity' of the eccentric projecting part of the pin C is made polygonal, so that by applying a wrenclnthe Apin may be turned to any desired posi# tion.
ln Ithe edge of the wheel A is out a notch,e, of such form that the head of the said screwwill lit into the same. Iuthat position, the head of the screw cannot become entangled by the cnt grass while the machine is in motion.`
The nut a being countersunkinthe wheel, part of its thickness, also' prevents itscatching the out grass, and the wheel can be hung nearer the bearing than it could otherwise.
TheA peculiar -orm ofthe pin and wheel-serves to inthe crank. Y
, Upon the end of the eccentric projecting part of the pin is arranged a mark or a-n index, which serves, in connection with marks upon the wheel, to show the distance of the eccentric projection from the centre of the wheel.
To turn the pin, it is only'neeessary to loosen the said screw d, when, by applying a wrench to the poposition. It will be seen,
fast, and the pin thus prevented from becoming loose by accident. f Having thus described my invention, Whatl claim as new, and desire to secure by Letters Patent, is
an eccentricl projection, thev set-screw d, arranged tov lock the pin4 iu any desired position, substantially as herein shownA and described.
for receiving the set-screw d, substantially as herein show n and described.
IHIRALM, L. WANZER.

ORRIN HAWLEY, ARTHUR E. KNoWLEs.
` crease the Astrength without increasing the weight of lygonal'outer Dart of the pin, it may be turned to any that by the use of the said screw d, thepin may be adjusted without loosening the same from' the wheel, and 'thenut a can therefore vbe made' 1. In combinationwith a crank-pi.n, C, which has E 2. The pitman-wheel A of a harvester, when notched
