Fig. 3 is a cross section on line y y, showing the screen frame, and feeding devices as shown in Fig. 2. Fig. 4 is a horizontal section, substantially on a plane of line z ,c in Fig. 3. Fig. 5 is a cross section subz 5 stantially in the vertical plane on line o o in Fig. 4. Fig. 6 is a detached perspective view showing the feed device applied` to a screen.

Fig. 7 isa vertical -section through a frame and screen showing `a modification of the 3o cation of feed device. Fig. 9 is an enlarged section through the crank shaft, crank and: screen. Fig. 10 is a section centrally through Fig. 9. Fig. l1 is a horizontal section online H, Fig. 9.

A is a supporting frame.

B is a box frame suspended therein, and which may be the `screen Aframe as shown in Fig. 1l, but I prefer to use and have shown in the other views a separate slidingscreen frame C preferably suspended by links C to reduce friction in the frame'and covered with a screen D of any suitable material. The

object of using each separate screen frame, is to enable me to use' a specific knocker device which is adapted for keeping clean the meshes yof the screen. The screen frame at one end i 5.o is backed by springs E and in the motion of the device is intended to be shocked or j arred.

.frame and showingv the feed device illustrated f 1n Fig. 6. Fig. 8 is a detached perspective view similar to Fig. 6 showing another moditiy Serial No. 507,322. (No model.)

The mechanism which I preferably employ I will describe hereinafter.

The frame and screen are gyrated from the vertical shaft G j ournaled in the frame, driven from any source of power and carrying the disk or fly wheel H at its lower end having a crank connection H with the frame or screen. At the present time such gyrating screens are `in use, driven from a crank shaft, and are commonly known as plansifters. In their use the centrifugal force of the box is sufficient to rock the frame, unless it is tightly bolted tothe floor, andthen it exerts the rocking lstrain to the building, often resulting in serious damage or trouble. I overcome this difficulty by balancing the device and preferably accomplish this by arranging on the disk H opposite the crank connection, a counterbalance weight I, so arranged that it may be adjusted radially, as by the bolt I,in the slot Z2 of the disk.

Thus the frame or screen may be balanced, at any speed or with any material, and experiments have shown that, with my attachment even with the frame resting loosely, on the floor, if carefully balanced, no rocking will take place in the operation. The knocker or jarring device I have shown works by the tension of the springs E, and a connection with a cam-bearing on the crank pin or wrist H. Shown in detail in Figs. 9, `10, 1l.

E is an arm or rod on the screen frame having'a wear iron E2 on its end passing through a slot inthe bearing on the screen -in which the pin I-I works, and held therein by the spring pressure. The pin has a section cut yout oppositethis slot, to formthe cam face S and the should er or fiat face T all so arranged that as the crank pin moves from the posi- -tion shownin Fig. 11, the rotation thereof in its bearing will, through'the cam faceS move the arm and with it the screen, longitudinally, compressing the springs E. The wear iron will run on the periphery of the pin until it reaches the flat face T, when the spring will move the screen quickly a distance equal to the slot in the pin, jarring it and cleaning the meshes. f

I may arrange the box frame and screen as shown in Fig. 1 on a slight inclination so that it will feed toward the discharge end, or I may arrange it horizontally and may provide, and preferably do, other feed devices for the material which I will now describe.

The feed mechanism broadly consists of rotary gates adapted to be turned in one direction by the movement of the material over the surface near which they move and which act as a check or stop to prevent the return of the material, suitable devices being employed to brake or stop the reversal of the gates.

In applying the gates to the hopper or frame bottom I preferably arrange a feed all the way across but in applying it to the screen, I preferably arrange the gates, so that but a section or portion of the screen will have the feed gate in position at any one time.

In Figs. 4 and 6 I have shown the feed gates of the preferred construction as applied to the hopper or frame bottom and they consist of a series of plates or blades a, rotating from a common center, connected together and journaled at their ends upon trunnions b.

In the forward movement of the frame, the material in front of the blades will be held from backward movement, as in that movement the blades are locked by any suitable device. The means I have employed for locking them is in the nature of a brake, consisting of a strip or board J sliding in the side of the box and having apertures through which the trunnions b may pass a spring J', being secured to the supporting frame in such relation that it will bear upon the end of this strip in the forward movement of the screen and force the strip tightly against the trunnions, locking them from rotation and thereby braking the gates. As the frame reaches the limit of its forward movement and begins its return in the arc ofthe circle, the strip will pass o the end of the spring, as shown in dotted lines in Fig 4, thereby releasing the brake and permitting the gates to turn, to allow the feeding forward of the material in the return movement of the frame. n

In Fig. 7 I have shown a feeding device similar to that shown in Fig. 4, except that it is applied only to the trough .I 2 at the lowest point of the hopper bottom J 3 of the frame. When I apply this feeding device to the screen proper I prefer to so construct the gates that only a comparatively short section of each gate will be feeding at any one time, thereby increasing the time interval and movement of the material in passing over the screen. This I effect in any desired manner, such for instance as shown in Figs. 6, 7 and 8.

In Figs. 6 and 7 I have shown two sections c d of rotary gates, arranged at different angles to each other, or staggered, so that but one section will be feeding at each reciprocation of the screen.

In Fig. 8 I have shown another modication of this device,in which I have arranged a series of short blades a spirally about the supporting shaft or trunnion, so that but one short'bladewill form a feed gate at each reciprocation or rotation.

In place of using the brake it is evident that a ratchet and pawl device may be employed to prevent the reverse movement ot' the gates as shown at K, Fig. lO.

What I claim as my invention is 1. In a separator, the combination with a frame, of a screen loosely mounted therein, actuating means for the frame, and a connection between said actuating means and the screen for jarring the same, substantially as described.

2. The combination with a frame box, a screen movably held therein, means for gyrating the frame box and an extension on the screen engaged by said means for independently jarring the screen, substantially as described.

3. The combination with the screen and frame, a shaft, a crank thereon engaging said frame to impart a gyrating motion thereto, a fly wheel or disk on the shaft, having a radial slot opposite the crank, a eounterbalance weight and a securing bolt therefor adgustably engaging in said slot, substantially as described.

4. The combination with a frame containing a horizontal seive of a feed device for the material comprising rotary gates, adapted to rotate only toward the discharge end of the screen, substantially as described.

5. The combination with a frame containing a horizontal sieve of a feed device for the material comprising rotary gates adapted to be turned by the movement of the material toward the discharge end of the device, and means for preventing a reverse movement, substantially as described.

6. The combination with a frame containing a sieve of a feed device for the material on the sieve, comprising a series of rotary gates, each gate having a number of sections adapted to be brought successively into operative relation to the sieve, substantially as described.

7. The combination with the frame and sieve, of a feed device for the material on the sieve comprising a shaft and a spirally arranged series of blades thereon adapted to be brought successively into operative relation to the sieve, substantially as described.

8. The combination with thegyrating frame and sieve, of rotary gates forming feed devices for the material, of a brake adapted to be applied to said gates only in the forward movement of the device, substantially as described.

9. The combination with the gyrating frame, and sieve of a series of rotary gates forming feed devices for the material trunnions upon which the gates are supported in the frame, a long strip through which the trunnions pass, and a spring against which the strip presses in the forward movement of the screen only, substantially as described.
