fro ALL WHOM 1T MAX coNoERiv: t

De it known that I, C. WHEELER, Jr., of Poplar Ridge, in the county of Cayuga, and State of New York, have invented a new and useful improvement in Cutting Devices for Harvesters; and Iv do hereby declare the following to be a full, clear, land exact description of the same, reference beinghad to the accompanying drawings, making a part of this specification, in whichi Figure 1 representsa top plan of a portion of the finger-bar and cutting apparatus.

Figure 2 represents an end view thereof. Figure 3 represents a longitudinal section through one of the guards. Figures 4 and 5 are cross-sections through the guard, taken respectively at .the red lines .x ,x and y y of fig. 3; and

Figure 6 represents a top plan of a portion of the ledger-plate detached from the guard. The nature of. this invention relates,'rst, to the arrangement of a ledger-plate with a guard-linger so as to use-it in a cutting apparatus thathas a, scalloped cutter, thev rear part of .which and the bar to which they are fastened, when in operative position, are overthe finger-bar, 4and in providing plates restingon the finger bar-as supports or bearings for the projections of the cutters, and prevent them' from bearing directly on the ingerbar. It further relates to the forming of a recess in the upper Asurface ofthe guard-finger, extending from the finger-bar to the point of intersection oi' the cap piece, and to the manner of locking the ledger-plate laterally to prevent it from mving in that direction. It further relates to the combination of the ledger-plate, guardfnger, and its cap piece, so as to form the slot, through which the cutter vibrates, wider at its rear than at its front end; and it further relates tothe supporting -of the rear end of the cap of the guard by uniting it to the body of the guard behind the nger-bar, and having an open space between the cap and ``1nger-bar for the operationof the cutter. i

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.

B represents the'nger-bar, which I propose to construct of iron. The ngers C are attached to the fingerbar B by bolts avpassing verticaily through said bar, one bolt through each finger.. The back ends of the fingers C extend upwards, anidiso bear against the bar B as that one bolt a is sufficient to secure each guardinger to the bar. The front end of each guard-finger is notched in a dove-tailed manner to receive the `front end of the cap D, which is' of a curved or arched form, as clearly seen in iigs. 2 and'3, and the back ends of these guard-ngers,'or'rather the caps thereof, are secured by bolts Z5. The front parts of the guard-hugues, on their upper surfaces and underneath where the `ledgenplate E lies, have each alongitndinal groove or recess, c, made in them, and these grooves or recesses receive the projections d on the underside of the ledger-plates E respectively, 'which rest upon the guard-fingers, the back ends h of said plates projecting over and resting upon the ngerbar, as shown in the drawings, figs. 41, 2, 3. The front ends of the caps D have projections e on-them, which pass through the' open mortise il in the .front ends of the ledger-plates E, and then enter the grooves or-recesses c in the ugers or guards 0thusho1ding' themselves and the led'gerfplates E firmly to the guard-finger at that end. The plates E have their edges j j'slightly .bevelled, as shown at iig, 5, so as'to form cutting edges et their upper surfaces to make, in connection with the scalloped sickles, ashes-r cut for severing the stalks between them.; 'and the upper surfaces of the ledger-plates E may be faced with. steel or they may be cast of hard metal. The sickle-bar Fis `furnished with triangular o r scalloped-shaped teeth or cutters,f, and works in, through, or under guides g attached to the upper surface of the finger-bar B, as shown in figs. 1 and 2. The cutting edges of the sickles terminate at or near the front edge of the finger-bar. The caps are sufficiently curved or arched to allow the sickleibar Fte work freely underneath them, and also to clear the nuts of the bolts a. The heels c of the sickles res-t and'work on the rearpa-rts h of the'plates E,

which keep the sickles freefrom contact with the finger-bar, but allow thecutting edgesof the teeth or sickles to work close over the cutting edges of the ledger-plates E, and to form with them a shear and clean-cut.

The advantages of my improvement, as has beenlfully proven in praetice, are, first, the fingers and caps, connected and attached to the ngerfbar, as shown, possess a great degree of strength with-small Weight of metal, and either maybe readily removed and replaced by others 'should they be broken second, the plates E are conveniently removed to be ground when necessary, or to be vreplaced. by new ones, if new ones should be required; third, by locking the caps and guard-fingers together, as shown, their construction is much facilitated and cheapened; fourth, b'y attaching the guard-lingers to the finger-bar in the manner shown, one bolt will hold each guard firmly in place, Whilst the nut does not obstruct the free passage of the' eut grass or grain over the l nger-bar; iifth, by placing the sickles cr cutting teeth on the top of the ngerbar, as shown, the cut grass or grain has only the breadth of the finger-bar to pass' over, and the free passage of the gra-ss or grain over the bar is insured; sixth, by giving the caps a curved or arched form,'in addition to their strength they assist-n raising lodged or tangled grass in. their passage through it, and give the sickles or cutter a better chance to operate freely without clogging; seventh, the plan, shown of fitting and holding .the ledger-plates to the guardnger obviates thene'eessity of bolts, 1ivets,'"or other separate fastenings for holding them in place.

'Having thus fully described my; invention, what I claimvtherein as new, and desire to secure by Letters Patent, isf i i v I claim7 in combination with the guard-finger, ledger-plate, and scalloped cutter, as described, the plate resting on the fin'gerbar as a. bearing forthe rear projections of the cutters', and to give an open space between the cutters and linger-bar for the passage of dirt. and grit, substantial-ly as described. o Y

I also claim, in combination with a ledger-plate, agnard-finger having a rigid cap and an open space behind the cutters, a recess in the body of the guard extending from the point of connection of the cap with the body of the finger back tothe nger-bar, substantially as, described. I l

I also claim the ledger-nlate-locked with the guard-ingerby projections on the under side of. the plate, so as to prevent lateral movement, in combination with the ledge, toprevent vertical movement at its front end. substantially as described. f 4

I also claim the combination of the ledger-platewith the giiarddinger so as to make a finger having'a slot through which the cutter vibrates that is Widervertically at its hack than at its front end, and that has 'an enlarged opening in vrear of the eutterfbar for the discharge of grit, fibre, Snc., substantially as described.

I also'claim arching the cap vvof the guard-finger and extending'it back and uniting it to the .body of the guard-nger in the rear o'f the finger-bar, so as to form an open space between it .and the finger-bar for the' knife-bar andthe rearpart of the cutters to operate in, substantially as described.
