@wird tate WILSON ELDER, OE MILL HALL, PENNSYLVANIA.
Letters Patent No. 95,887, dated October 19, 1869.
IMPRQYEMENT IN STRAW-CUTTERS.
The Schedule referred to in' theseLetters Patent and making part of the same To allfwhom it may concern Be it known that I, WILSON ELDER, of Mill Hall, in the county of Clinton, and State of Pennsylvania,
have invented a new and useful Improvement in Strawl Cutters; and I dohereby declare that the following is `a full, clear, and exact description thereof, which will Figure Sis an inside view of the end of the cut-terlever, which works on the fulcrum and Figure 4 is a view of the fnlorum-pin.
Similar letters of reference indicate corresponding arts. p The metallic plate A,.which is tted to the end vof the box, aud has the large opening, through which the straw passes to be cut, is provided with a large circular end around the hole, for the fulcrum-pin, and the end B of the lever O is correspondingly enlarged, so that when they are clamped together lateral movement of the lever will be prevented as much as possible.
The hole through the said enlargement of the part A, for the fulcrum-bolt O, is round,'and the bolt, which is inserted from the rear side thereof', is correspondingly rounded, as shown at D; but the hole in the lever at the inner side is of square or other angular form, as shown at E, and the bolt similarly squared at F, and the tightening-nut G is screwed up against the part B.
By this arrangement, the bolt and` nut turn with the lever, and the lnut is prevented from working loose.
On the inside of the enlarged part B are curved projecting ribs or bearings H fitted into grooves, in which, behind the ribs, I place India rubber, or other yielding, or springing substance, to prevent too great pressure of the projections H against the plates A when screwed up, and when thus screwed up against the springs, the two parts are suficiently confined to prevent any lateral movement of the lever, and the knife is not pressed too strongly against the plate A.
I is an annular groove formed in both the parts A and B, the object of which is to alord as small an amount of frictlonal surface as possible between said parts.
it has, in a greater measure, the action of a shear-cut at the commencement, which is less laborious than if straight.
Having thus described my invention,
What-I claim as new, and desire to secure by Letters Patent, is
The enlarged part B of the lever O, elastic bearingribs H H, annular groove I, plate A, and bolt O, all combined, constructed, and arranged as specified.
WILSON ELDER.
