SELF-FEEDER `FOR TH RASHlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 251,799, dated January 3, 1882. Application tiled July 20, 1881. (No model.)

To all whom it may concern:

Beit known that I, JOHN SGHOLL, a citizen of the United States, and residing at Elk Grove, in the county of Sacramento and State of California, have invented a certain new and useful Self-Feeding Attachment for Tlirashing-Machines, of which the following is a specification.

My invention relates to improvements in selffeeding attachmentsfor thrashing-machines; and the object of my invention is to provide a machine so constructed that the grain in"the straw, after being dropped upon the feedingplatform, will be fed in a regular and automatic manner to the separator of a\ thrashing-machine. I attain this object by the mechanism illustrated in the accompanying drawings, in Which- Figure 1 is a longitudinal section through a portion of a thrashing-machine embodying Fig. 2 is a cross-sectional view of the same. T

Similar letters of reference are used to des- 4 ignate like parts throughout the several views.

The grain in the straw, as it is dropped from the fork, falls upon the gratingA, which is firmly secured to the main frame of the thrasher. Underneath4 this grating there is a movable grating, B, the slats of which correspond to the spaces in the stationary grating immediately above it. This grating is provided with upwardly-projecting teeth or rods UU. To the underside of this movable grating Iattachjournal-boxes GO, through which pass the cranks D D', the outer ends of which are journaled in suitable boxes set in the main frame of a thrasher. y

Upon the outer end of the crank D, I key the two pulleys E E', and upon the end of the crank D', I also key a pulley, (not shown in the drawings,) which is connected to the pulley E by an endless belt or band.

Beneath the movable rack is placed the graincarrier or endless belt G, which receives al1 kernels of grain that may be shaken out, and which fall through the gratings A B. At any convenient point along this grai n-carrier I place the drum H, upon'a shaft, I, upon one end ot' which is keyed the pulley J, connected by an' endless belt or band with the pulley E. The other end of the shaft is provided with the pulley K, connected by a suitable belt with the pulley L upon the crankshaft M. Between i theside boards of the thrasher, andfnpon the said shaft M, I place the roller N, provided with projecting teeth or spikes O, the ofce of which will be more fully explained hereinafter.

Upon the outside of the machine, and about on a line with the inner end of the grating or screen A, I attach the guide-pieces P P, which are set slightly inclined toward the outer end ot' the machinefThat portion of the guidepieces which extends above the top edge of the thrasher is slotted, as is clearly shown in Fig. 1, said slots forming a bearing or guide, in which rises and falls the cross-bar Q., provided with downwardl y-projectin g rods or teeth R B. To the outer ends of this cross-piece are firmly secured the connecting-rods S S, the lower ends of which are pivoterl upon the crank-shaft M, as is seen at Fig. 2.

The operation of my improved self-feeder is as follows, to wit: The proper belt-connection having been made and the machine putin motion, the grain in the `straw is deposited by any well-known means upon the feed-grating A and as the cranks D and D are revolved they carry with them the feeder or movable grating B and impart a rotary reciprocating or fourmotion feeding movement toit, or, in other words, the feeder is so moved as to rise toward the stationary grating, move forward horizontally, fall to its former level, and assume its original position again. This movement will canse the upwardly-projecting teeth or rods secured upon the feeder to pass upward through the slots in the lixed grating, enter the lnass ot' straw and grain upon the feedgrating A, and force it forward in an intermittent manner to the separator.

The amount of material which is fed to the separator is regulated and controlled by the action ofthe bar Q and downwardly-projecting teeth R,'so that as the teeth U of the feeder B advance they will force the straw toward the separator, and the said bar Q will rise in its' guides and permit a certain quantity of straw to be forced over the end of the feed-grating. Direction is given to it by the roller N, the projecting teeth of which roller will assist in directing the grain to the throat leading to the separator. As the feeder is resumingits origi- IOC nal position preparatory to carrying forward another quantity of straw containing grain to the separator the cross-bar Q will descend in its guides and its teeth prevent any surplus straw or grain from passing to the separator.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

In a self-feeding attachment for thrashinglnachines, the combination, with the fixed grating A and movable grating' B, having journalboxes C O and teeth U, the latter adapted to enter the spaces in the upper grating, of the crank-shafts D D, pulleys E E', grain-carrier G, drum H, having a shaft, I, carrying pulleys x5 J K, the roller N', provided with teeth O, Acrossbar Q, having teeth R, and suitable connecting and operating' mechanism, substantially as and for the purpose shown and described.

In testimony that I claim the foregoing I zo have hereunto set my hand and seal this 29th day of June, 1881.
