THOMAS E. PHILLIPS, OF BLAIR, WVISOONSIN.

. SEPARATO R.

SPECIFICATION forming part of Letters Patent No. 356,329, dated January 18, 18E7,

Application filed June 24, 1886. Serial No. 206,121. (No model.)

To IZZZ whom, it may concern:

Be it known that I, THoMas'R. PHILLIPS, a citizen of the United States, residing at Blair, in the county of Trempealeau and State of WViscousin, have invented certain new and useful Improvements in Separators; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, refer ence being had to the accompanying drawings, and letters of reference marked thereon, which form a part of this specification.

Likeletters refer to similar parts throughout the several views.

Referring to the drawings, Figure 1 is a side elevation of my improved separator with parts broken away. Fig. 2 is a longitudinal vertical. section of the same.

This invention relates to separators, and has for its object to simplify and cheapen the construction and render more efficient in operation this class of machines; and the novelty consists in the peculiar combinations and the novel construction, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the drawings, and specifically defined by the claims.

Referring by letter to the drawings, A represents a suitable frame, preferably rectangular in form. At the front end of this frame, and preferably to the end uprights thereof, are secured the brackets or bearings B, of any suitable construction.

0 is a shaft journaled in said brackets, and D is a drive-pulley secured to one end of said shaft, which may be connected by belt with any suitable source of power.

E isan inclined trough supported upon springs a, attached to the frame, as shown. This trough consists of the parallel sides E and a concave bottom, I), inclining from both ends, and at the junction of the two inclines, which is preferably near the lower end, it is formed with a dischargeopening, c.

F is a sieve, of slightly smaller dimensions than the trough E, and is inserted therein, between the side walls thereof, in the following manner: A short distance from each end of the sieve, preferably about one-quarter of its length, I secure to the under side of the frame of said sieve crossbars (Z. c are springs, one

end of each of which is secured to the said bars and the other end to the cross-bars of the trough, as shown. These bars d are secured at their ends in the side bars of the screenframe and serve to better hold the cloth of the screen to its frame at these points and prevent the sagging of.the cloth, as will be readily understood. The upper surfaces of these bars are tapered, as shown, so as not to interfere with the passage of the liour through the cloth. While I employ fon r springsone at each corner of the sieveI do not'wish to confine myself to this exact number, as I may sometimes find it desirable to use but two-one at the center of each end of the screen-or I may sometimes use a greater number. This supporting of the screen on springs in this manner leaves the same free to vibrate in all directions when the machine is in operation. The side walls of the trough are perforated, as shown at f, so as to admit air beneath the screen for the purpose of ventilation.

G is an eccentric centrally secured on the shaft G and connected by means of a rod, 9, with the bar 72, secured to the bottom of the trough. On the outer end of the shaft 0 is another eccentric, H. At the opposite end of the frame, and near the upper end of the end uprights, there are secured the brackets 'i, in which is journaled the rockshaft I. Secured to this rock-shaft are the striker-arms J. c In the present instance two are used, but more or less may be used, as occasion may require. Each of these striker-arms carries at its free end a hammer or knocker, j.

K is a knocker-plate secured across the top of the sieve frame, and against which the knockersstrike. Thisstriker-platealsoserves as a brace to strengthen the screen-frame.

In order to be able to regulate the length and rapidity of the stroke of the knockers and to increase or diminish the force with which they bear upon the plate K at the beginning and end of each stroke, I provide the following mechanism: Secured to the outer end of the rock-shaft I is a casting, L, provided with a vertical screw-threaded aperture,with which engages the adj usting screw-rod M, the lower end of which is attached to the yoke N, be tween the arms of which is secured one end of the pitman P, the other end of which is connected in any suitable manner to the eccentric II. By adjusting the rod M by means of its thumb-piece m the length of the stroke of the rod M is regulated and the knockers thrown against the knocker-plate K more or less rapidly, according as the rod is adjusted up or down.

In operation, motion being imparted to the shaft 0, and by means of the eccentric G and its connection with the trough, a reciprocating motion is imparted to the trough and the screen carried thereby, and at the same time and by the same movement motion is imparted to the rockshaft I, causing the knockers to rise and fall and in their descent strike against the knockcr-plate on the screen-frame, jarring the same and keeping the cloth free and preventing the same from cloggin Having thus described my invention, what I claim to be new, and dcsi re to secure by Letters Patent, is

1. The combination, with the trough and springs supporting the same, of springs e, secured at opposite ends of said trough, as described, bars (I, the screen secured to and resting upon the bars (I, secured to the free ends of said springs c, the bar It, secured to said trough, and connections between said bar and the drivingshaft, substantially as and for the purposes specified.

2. The combination, with a frame, a trough, and a screen yieldingly supported thereby,

of a shaft journaled in said frame, an eccentric secured to said shaft, connections between said eccentric and said trough, a rock-shaft journaled in said frame above the trough and carrying knockers, and connections between said shaft and rock-shaft whereby the trough is reciprocated and the knockers operated from the same shaft, substantially as described.

3. The combination, with the yieldinglysupported trough and screen of the rock-shaft I, knockers j, carried by said rock-shaft, casting L on said rock-shaft, rod M, adjustable in said casting, yoke N on the lower end of said rod, and connections between said yoke and the driving-shaft, and connections between said shaft and the trough, substantially as described, and for the purposes specified.

4. The combination, with the yieldinglysupported trough and screen, of the rock-shaft I, carrying knockers j arranged above said screen, means for simultaneously reciprocating said trough and screen and operating said knockers, and means for regulating thelength and rapidity of stroke of said knockers, substantially as described.

In testimony whereof I aflix my signature in presence of two Witnesses.

THOMAS R. PHILLIPS.
