HVIPROVEM ENT IN HARVESTER-RAKES.

Specification forming part of Letters Patent No. E 3,911?, dated March 24, 1874; application filed February 2, 1874.

To all whom it may concern:

Be it known that I, THOMAS G. GLOVER, of Bedford, Lawrence county, State of Indiana, have invented certain Improvements in Reap ers, of which the following' is a specification:

The object of my invention is to provide for and produce certain attachments to reapingmachines, which forms a self-raker, or automatical raker of the grain from the table of the machine after being cut. These attachments are cheap and simple in construction, not liable to be deranged or get out of order, and will operate with ease and certainty. Y

Referring to the accompanying drawing, forming part of this specification, Figure lis a plan view of a self-raking reaper embodying my invention. Fig. II is a back view of the same. Fig. III is a detached face view of the cog-wheel, showing the ratchet-wheel and pin. Fig. IVgis a sectional view of the same.

My invention consists in securing to the frame A of an ordinary reaping-machine, just over the table T, upon which the grain drops, a movable rake, Q. This rake is then secured to a frame, R, on which it slides in suitable guides 7 r. The frame R is hinged at o o to two supports, S S, which allow it to be raised and lowered, as the case may be. The movable rake Q is caused to slide on the frame R by a connecting-rod, P, one end of which is pivoted to the rake Q, and the other to the vertical arm O. This arm is secured to the outer end of a shaft, n, in the rear of the frame A of the machine. To the other end of this shaft n is secured a rocking bar, M. To the ends of this rocking bar are loosely fastened two cross-bars, L L, which are hinged to the bar Kin the front ofthe machine. These bars are raised and depressed bythe adjustable pins 71l h on the wheels G, which are fastened to the axle D. The pins h h are inserted into slots i i in the wheel G, and held in any desired position by set-screws. This is done for the purpose of giving the rake a short movement over the table. To the outer end of the axle D is secured a loose cog-wheel, E, which gears into another cog-wheel, d, on the main drivin g-shaft C, said shaft having two driving-wheels, B B, on its ends. Alongside oi' the cog-wheel E is secured iirinly to thel axle D a ratchet-wheel, F, with a paw1,f, fastened to the eogE. The object of this is to prevent the rake from moving when the machine is backed, and also to enable the machine to be carried to the iield without operating thc rake.

To automatically raise the frame It I place on the inner end ofthe axle I) a cam-wheel,V, which, at each revolution, raises and lowers a connecting-rod, XV, one end of which ishin ged to the frame A at O, and the other to the rake frame R, at 1.

To prevent anything from accumulating on the table T, and also to make it lighter, I construct the bottom of the same of a number ci' slats, a u, ruiming parallel to each other.

The operation of my machine is as follows: As the grain is being. cut the cam V, by aid of connecting-rod XV, raises the frame It, and allows the grain to fall on the table T. This accomplished, the frame R drops back to its former place, and the rake Q is drawn across the table T, forming one bundle and clearing the table for another.

Having thus described my invention, I desire to claim- The movable rake Q, the movable frame R, cog-wheels d and E, wheel G, pins IL 7L, rods L L, vertical arm O, connecting-rods I) and XV, and cam V, in combination with the slatted table T, frame A, axle C, and wheels B B, substantially as and for the purpose hereinbefore set forth.

THOMAS G. GLOVER.
