STARCH-SEPA RATO R.

SPECIFICATION formingV part of Letters Patent No. 261,445, dated July 18, 1882,

' Application led April 10, 1882. (Nomodehl starch stock is placed, and which are agitated or shaken to separate the coarser particles ofstock from the finer amylaeeous particles, which pass through said bottoms, and which are afterward manipulated to form starch.

The invention consists in the combination, with such aseparator bolting-frame, of a novel combination of devices, hereinafter particularly described and claimed, for supporting the same, so as to provide for shaking or reciprocating it rapidly and for imparting such a motion toit.

In the accompanying drawings, Figure l represents a plan ot' a machine embodying my invention. Fig. 2 represents a side view there; of.' Fig. 3 represents a transverse section ot' one side of the bolting-frame and its supportingbox, showing the devices forsupporting one end of said bolting-frame; and Fig. 4 represents asimilar view, showing the devices which support the other end of said bolting-frame.

Similar letters of reference designate corresponding parts in all the figures. Y

A designates the stationary box or receiver of the machine, which has an imperforate bottom, at one end of which may be an opening for the discharge of the material delivered into it.

B designates the shaking-frame, which has a bottom of'bolting-cloth or other reticulated or foraminous material, and which tits above and within the box A, bothl it and the box A being in an inclined position, as clearly shown in Fig. 2. The stationary box A rests on and is supported by a frame-work, O, while lthe shaking-frame B is supported by the said stationary box. One end of the bolting-frame B has a sliding support, while'the other end has a swinging support. The sliding supports are formed by tracks C' on the box A and shoes or slides D on the bolting-frame B. The tracks C are here shown as composed of angleand loose pulleys L Lu pieces, which rest upon the top edges of the sides of the box A and are screwed or bolted tothe outer sides thereof, as clearly seen in Fig. 4,' and the shoes orA slides D are bolted or otherwise secured to the sides of the frame C and run in grooves b in the tracks C.

At the end of the box A opposite to that at which are the sliding supports are upright standards or bearings E, to the upper ends of which, above the box A, are pivoted links or bars F, which are adapted to swing or vibrate on their pivots c. At the sides of the bolting-frame B are secured standards or bearings G, which project above the frame B and are connected to the upper ends of the links or bars F by pivots d. The standards or bearings E and G may he considered as parts of the box A and frame B, respectively, and it is obvious that the links or bars F may swing freely back and forth to permit ot' the recprocation ot' the boltingframe B. The links or bars vF are short, and hence it will be seen that as the bolting-frame B is reciprocated it also has a rising-and falling motion at one end, due to the arcs described by the pivots d, and such rising-and-falling motion renders the bolting-frame much more effective in its operation. By this arrangement of links or bars F, I am not only enabled to make them short, but with a given amount ot'longitudinal movement of the Screen I obtain a relatively great rising-andfalling movement. To enable me to make these links or bars F so short, I pivot them at their lower ends to the side walls of the receiver, as before stated, all of which is of considerable advantage over those machines of a similar nature wherein long vibratory arms are connected at their lower ends to a horizontal transverse shaft rocking in bearings secured to the bed-frame of the machine.

H designates pitmen or connecting rods connected directlyT to wrist-pins e on opposite sides ofthe bolting-frame B, and actuated by cranks I on the ends of the shaft J, which is mounted in suitable bearings, K, and may be rotated by a belt, for which are provided fast The shaftJ may also have a fly-wheel, M, for making its rotation more uniform.

In lieu of the two rods H, a single rod cong nected to the bolting-t'rame B at about the middle of its Width might be used.

The starch stock is placed in the boltingframe Il, and by its reciprocation all the finer amylaceous particles which are to be manipulated to makestarch arecaused to pass through the reticulated or foraniinous bottom thereof, while the coarser particles are retained thereon and are delivered separately.

I am awarethatthebolting-frame ofastarchseparator has been suspended above a stationary box or receiver by upright arms connected with the bolting-franle and pivoted at their lower ends to the iioor which supports the boX or receiver; but such I do not claim.

VVhatI claim as my invention, and desire to secure by Letters Patent, is-

In a starch separator composed or' a stationary box or receiver, a bolting-fralne, and mechanism for reciprocating the latter, the herein-described devices for supporting the bolting-frame on and above the box or receiver', consisting ofthe vertical standards E E, rigidly seeured to and projecting above the side Walls ot the box or receiver, the vertical stand ards G G, rigidly secured to and projecting above the side Walls of the bolting-frame, and the short links F F, having their lower ends pivoted to the standards on the box or receiver and their upper ends pivoted to the standards on the bolting frame, all substantially as shown and described.
