THRASHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 242,846, dated June 14, 1881. Application filed November 10, isso. (No model.)

.To all whom it may concern:

' State of Colorado, have invented certain new on the inclined driving-shaft- D.

and useful Improvements in Thrashing- Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use 1 he same, reference being had to the accompanying drawings, which form a part of this specification.

The object of my invention is to provide for certain improvements in thrashing-machines, whereby simplicity of operation and an increased degree of-efticiency are combined with durability and lightness of construction, as hereinafter more fully described and "claimed.

Referring to the annexed drawings, in which corresponding letters indicate like parts in the several views, Figure 1 is a front-end view of my improved machine. Fig. 2 is a rearend view. Figs. 3 and at are opposite side views. Fig. 5 is a longitudinal section. Fig. (i is a top view, and Fig. '7 is abottom view.

A represents the frame-work that sustains the several operative parts of the machine. At its front end is arranged on oneside a semicircular feed-box, B, open in front and at each side, the inner side being provided with a rim or flange, b. The inner surface of the box B is provided with diagonal ribs 1), that, together with the rim I), serve as guides to direct the grain into and through the slotted hulling-cylinder O, which passes through the feed-box and extends between the frame of the machine on each side, where its shaft 0 isjournaled in suitable bearings. This shat't carries atone end a pulley, c, and at its opposite end a pinion, 0, which gears with a toothed wheel, D,

Thedrivingshaft D is supported in bearings (1 cl, and carries at its upper and rear end a pinion, d, that gears with a toothed wheel or pulley, E, on the shaft E.

Immediately back of the feed-box Bis a short vibrating separator, F, which is arranged in an inclined position, and provided with longitudinal notched ribs or a forward-projecting toothed carrier, f.

Above and to the rear of the separator]? are two heaters, G G, which are provided with blades 9 and divisions or pockets 9. These heaters are arranged to revolve toward each other and separate the grain from the straw, that passes up from the separator F and then on between the heaters. The grain falls into the pockets 9, whence it is emptied onto a long vibrating separator, H, that is also arranged in an inclined position beneath the separator F and heaters G G and extends nearly the entire length of the machine. The lower part of this separator is provided with transverse corrugations h for about one-third its length, its remaining portion having perforations h and longitudinal notched ribs or toothed carriers h that convey the straw to the stacker. The separators FH are provided with central longitudinal braces above and with suitable transverse supports beneath, to which are pivoted their operating links or levers.

Beneath the lower separator, H, at its upper or rear end, is a sieve, I, having at its rear end a hinged portion, 0', and between this sieve and the separator is a trough or conveyer, 1, arranged on one side for the removal of coarse stuff, both sieve and conveyer being secured within the upper part of a double shoe composed of the two sections K K. This shoe is suspendedfrom the frame of the machine by means of pivoted links or straps a a, so as to have a vibratory or shaking motion when operated. Its upper section, K, is provided with a transverse spout, 70, at its rear end, that has a pitch from the center to each end at the side of the machine. Through this spout the contents of the upper section of the shoe may be discharged into the conveyer M below the rear end of the lower section, whence they may be passed, if desired, to the elevator. WVithin the lower section, K, are placed the sieves L L, which are secured to a pivoted frame, L, so as to render them capable of being arranged in any desired position. The separated grain contained in this section, passing through an opening or slot in its bottom that extends from side to side, will fall into the grain-trough N suspended beneath, which is caused to reciprocate from side to side and, deliver the grain to sacks arranged to receive it.

The revolution of the slatted cylinder 0 usually causes a sufficient current of air to blow off the dust and chaff; but, if desired, an ordinary fan can be also employed, being arranged below the cylinder at the lower end of the separator H, and driven by a belt-connection from the pulley c on the cylindershaft 0.

When the driving-shaft D is operated the gear-wheel D, meshing with the pinion c on the cylinder-shaft G, revolves the cylinder 0, and also communicates motion, through the pulley c and a suitable belt-connection, to the fan-blower beneath. At the same time the pinion d, meshing with the gear-pulley E, revolves the latter, which transmits motion through the endless belt (2 to the pulleys g on the shafts of the beaters Gr G in such a manner as to cause them to revolve toward each other. The belt 0 also communicates motion to the pulley m on the conveyer-shaft M, and to a band-wheel, 0, on the shaft 0 at the lower front partot' the machine. An idler or belt-tightcner, a, may be arranged between the pulley m and wheel 0, if desired.

On the end of the shaft 0 opposite to the band-wheel O, is a small crank-wheel, 0, to which is pivoted the pitman 1. This pitman is also pivoted to a lug, 29, secured near the center of the connecting-rod Q, the latter bethat the separator H moves to the rear.

ing provided at each end with links q g, by means of which a semi-rotary movement is imparted to the rock-shafts R R, to which the links q q are also attached. These rock-shafts are connected with the separatorH by means of links r r on each side, which thus impart to the separator a vibratory reciprocating motion. The rock-shaft R is also provided'with links r that operate the double shoe K K through the rods 7: attached thereto on each side.

On one end of the rock-shaft R is a link, s, that is pivoted to the connecting-rod S, the latter being also pivoted to a link, 8, on the rock-shaft T, which is connected by links if t with the separator F. The separator F, being loosely pivoted at its lower end to the frame of the machine, is operated in such a manner as to receive a vibratory or shaking motion It will thus be seen that the motions of the separator 1* and double shoe K K counterbalance the motion ofthe separator H; or, in other words, the separatorF and shoe K K move toward the front of the machine at the same time ln this way the grain is conveyed from one to the other and the straw passed to the stacker with regularity and precision of movement, while the shaking up-and-down-motion or vibration of the separators insures complete separation of the grain.

To the connecting-rod Q is attached one end of a lever, U, which is secured at its other end to an arm, 'v, on the upper end of the inclined rock-shaft V. This rock-shaft is journaled in suitable bearin gs, and carries at its lower end another arm, 2;, arranged at a right angle to the arm n and carrying a rod, W, which is secured to the lower part of the grain-trough N, and thus imparts to it the necessary motion.

As previously stated, thcfeed-box or concave B is only about one-half the length of the cylinder, and is provided with a flange, b. The object of this arrangement is to provide an efficient means for huliing clover, since the straw can be introduced at the space which is at the upper side of the feed-box, and the cloverheads be extended in the feed-box, with the straw out of the same, the flange 11 serving to retain the seeds within the box, and the space to one side of the box allowing the straw to pass back to the separators.

From the foregoingdescription, in connection with the annexed drawings, the operation and advantages of my improved machine will be readily understood. The machine is compact, durable, and effective. Any suitable power may be applied without the necessity of disarranging its parts, and by its use all kinds of grain can be readily separated with great speed and economy.

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

1. In a thrashing-machine, the combination, with the rotary slatted hulling-cylinder O, of the semi'cylindrical feed-box B, provided with the ribs 1) and the flange b at its inner end, which terminates about midway of the length of the cylinder, said feed box being made shorter than the cylinder, as and for the purpose specified.

2. In a thrashing-machine, the combination, with the vibratory inclined separators F H, having longitudinal notched ribs or toothed carriers, of the heaters G G, provided with pockets 9, and arranged on shafts revolving toward each other, substantially as and for the purpose herein described.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in presence of two witnesses.
