CORN-SIFTER.

SPECIFICATION forming part of Letters Patent No. 298,429, dated May 13, 1884.

(No model.}

To all whom it may concern.-

Be it known that I, Jon TAYLOR, of Orchard Park, in the county of Erie and State of New York, have invented certain new and useful Improvements in CornSifters; and Ido hereby declare that the following description of my said invention, taken in connection with the accompanying sheets of drawings, formsa full, clear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

My present invention has relation to separators for separating the cobs and silks from green corn after said corn has been removed from the cob; and it consists in the construction and arrangement of parts, as will be hereinafter described and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of acorn-cutting machineprovided with my improved corn-sifter. is a front elevation of the corn-sifting device detached. Fig. 3 is a plan view of the cornsifter and the mechanism for supporting and vibratingthe same, the corn-cutter and certain other parts being removed in order to more fully show the details of my improvement. Fig. 4 is an enlarged detail view of the supporting-bar X and the Sifter-frame K, partly broken away.

The letter B in Fig. 1 of these drawings illustrates the so-called Sprague corn-cutter, being a well-known machine for removing the green corn from the cob, A and Abeing the frame thereof, as clearly shown in the drawings. This corn-cutter has a series of gear-wheels, O, to operate the feed-wheel, (not shown,) and into one of these gear-wheels I mesh a spur-wheel, D, fixed to one end of an axle or shaft, E, the other one of which is fitted with a crank-disk, F, said shaft being constructed to revolve in bearings G G, fixed to the frame A A in any suitable and convenient manner. To the wrist-pin f of this crank-disk is fitted one end of a connectingrod, H, the other end of which is connected to a lever, I, pivoted centrally within a bifurcated support, i, fixed to the frame A, said lever being connected with the Sifter-bar L by means of a contion, J, as clearly illustrated in the figures.

The mechanism heretofore described serves Fig. 2

to give a vibratory motion to a sifter-frame, K,'pivoted to a supporting-bar, X, which is supported by and suitably secured to the arms M M by means of pivots m at its inner ends, and adjustably secured to'the slotted portions n in the outer ends of the armsMM of the bar L, the thumb-screws 0 operating 011 screwthreaded bolts N of the frame K, whereby the front portion of said frame is raised or lowered in any desired position within the range of said slot-holes n.

The sifter-frame K is provided with aseries of lugs, 70, upon which rest two sifters, K K, (shown in Fig. 1,) consisting each of asuitable metallic frame, covered or otherwise fitted with wire-cloth of proper mesh, said frames being retained within said sifter by means of pins d, passing through said lugs 7. and the frame of the sifters K K as shown in Figs. 2 and 3.

The sifter-bar L is pivoted at a to the bar T, fixed to the sides of the frame A A, so as to sustain that end of said bar L farthest from the Sifter-frame K. To this sifter-frame are secured two arms, Y, which terminatein pivots 2 engaging the supporting-bars R, the lower ends of which are pivoted to lugs S, (shown in Fig. 1,) fixed to the frame A A. These supporting-bars R carry the frame K, with the sifters K K and are so arranged as to vibrate on the pivots in the lugs S.

It will be understood that when the corn-cutter is operating motion will be imparted to the machine through belt V, engaging pulley V upon the main shaft U. Such motion is also communicated to the sifting device by the wheels 0 and D andthe mechanism heretofore described.

The corn,witli particles of silk and cobs dis charging from the apron Z, Fig. 1, drops down into the frame K upon the upper sifter, K. The corn,being the smallest in size,is permitted to pass through the meshes of sifters K K while the cobs or other pieces thereof are retained upon said sifters, together with the silks, the -screened corn dropping into a pan, P, placed upon a suitable table underneath the sifters, while the cobs and other matter are discharged from the front portion, K, of the sieveframe (shown in Fig. 3) into any suitable and convenient vessel, not necessary to be shown.- As heretofore described, the sifters K K" are removably fixed within the frame K, so that whenever a portion of the cobs has accumulated thereupon, having failed to pass out at K of the sieve-frame, said sifters may be 5 withdrawn and the refuse matter removed from the meshes of said sifters.

Having described my invention, I desire it to be understood that I do not confine myself to the construction of the mechanism employed 0 for operating the sifters, as I may vary the same without departing from the invention or the true spirit and scope thereof.

What I claim is- 1. The combination, with the frame A A,

5 the arm T, the bar L, pivoted to said arm at a, and having the arms M M, the bar X, the frame K, pivoted at x a: to the bar X, and the as, the removable sifters K K, and the thumb-- nuts 0, for adjusting said frame by means of 25 the slotted arms M M, as set forth.

In testimony that I claim the foregoing as my invention I have hereto set my hand in the presence of two subscribing witnesses.

JOB TAYLOR.
