or DE 'KALB, ILLI- I Letters Patent No. 107,985, dated October 4, 1870.

(IMPROVEMENT m GRlNDERS FOR 'HARVESTER-CUTTERS.

The Schedule referred to' in these Letters Patent: and making'part of the lathe.

of De Kalb and State of "Illinois, have invented a Grinder for Mower. and Reapcr-Guards; and we do hereby declare that the following is a full and exact descriptionthereof', which will enable those skilled in the art to make and use the same, reference being had to theaccompanying drawing and letters marked thereon making a part of this specification, in which- Figure 1 is a perspective representation of our improved'grinder. p T

Figure 2, aplan view of the. stone, rest, 850.

The present'in-ventioh relates to a grindingmacl1ine which is designed to resharpen the fingers of fingerbars of mowers and reapers; and

. Its nature consists in a slotted rest and a traveling pulley-block, for supporting, by means of a chain, the

linger-bar, when the fingers are being ground.

In the present state of the art, when fingers become too dull to operate properly in grass or grain, they are replaced with new fingers, at considerableoostL But hymy invention theycan he. rcsharpened, and thus made to answer the purpose of new fingers. I

-In fig. 1, N represents floor or foundation, on which is a frame, L L, supporting the journal I of the Attached to that part of the frame shown at L is a projecting block or bed-piece, M, which supports a rest,M'.

This rest is so formed or :forked'as to pass by the periphery of the stone H, and onto its convex sides,

so that a suitable rest for a finger is provided on both sides of the stone.

E E represent substantial 'posts, which have a support on the foundation N, and which support a horizontal beam, E, on the top of which is fixed a metal track, B.

A pulley, A, in pulley-block 0, travels on the track B, and through the lower-part of the block 0 is put a chain, D, which, by means of hooks, suspends the finger-bar F at such height. as will allow the fingers G- to bear onthe'rest M, as shown in fig. 1. By this means the inner sides of any finger can be readily brought in contact with the stone, while at the same time the operator is not encumbered with the weight of .the finger-bar.

When the fingers on one part of the bar have been sharpened, the bar is moved longitudinally far-enough to bring other fingers-into position.

The stone His rotated by means of a band running over a pulley, K.

Clac' m.

The combination of the forked rest M, frame Ell, track B, pulley and block A O, and chain D, arranged to operate as and for the purpose set forth.
