10 alt whom it may concern:

Be it known that I, FERDINAND KAEHL technologist, a subject of the Emperor of Ger-, many; residing at 62 Gitsehinerstrasse, Ber-. lin, in the Empire of Germany, have invented certain new and useful Improvements in Centrifugel Separating Apparatus, of which the following is a specification.

This inventioh has for its object scentrifugal separating machine, by means of which starch, wheat gluten, and the like may be separated from water and dissolved con stituents. For the greater part the drums of known centrifugal machines consist of a shallow cylinder, the eriphery of which is conical in form and which is rovided with apertures for the dischar e of t e solid mate rial, while the specificel y lighter constituents issue through a perforated hub or through discharge-pi es erranged in proximity to the hollow s oft conveying the material to be treated to the'drum. In these arrangements the apertures on the conical periphery of the drum may he opened or closed by appropriate means. This may be effected, for instance, during the operation of the machine by the intermediary of pie tons and rods rotetin with the drum.

The device which (arms-the sub'ect of the present invention'dill'ers from the own arran emeuts as regardsits construction, owing to t- 1e feet that the drum consists of two conical halves joining each other at an oblique angle and provided with two perforated incased hubs of different sizes, one of whicl'l and also the drum is surrounded byn ring for catching the water and solid material, respeotively, and also by the feet that the s ides serving to open and close the apertures in the drum may be operated by hand by means of a fork displueesble upon a screwsgindle and not rotntingwith the drum. The s allow conical formamon of the drum per mite of speedy settling of the solid constituents end gradual sliding of the same along the inclined wells to the disohergeepertures By means of the hollow hubs of different diameters an unimpeded supply of the ma. terial to be treated and discharge of the so arated liquid is able to take place during tlih operation of the machine, and this'while dispensing with a hollow shaft or disks prevents" mg the dliBGl; discharge of the material from the other hub.

The invention is illustrated, by Way of ex' ample, in WlllOh Figure 1 shows the machine in vertical sec- -tion. and 3 show the catchingq'ing for the drum with the adjustable fork in section and in side elevation, res Jectively, upon a smaller scale; and Fig. 4 sh ion 'tudinal section a slide for the drugzn. e centrifugal drum consists of two hollow conical halves a and b, which are united at an oblique angle by means of an annular V U-iro11or in any other convenient mentor. The drum halves are carried on the horizontel shaft d by means of perforated hubs e f, the diameter of e being greeter than that of f. Upon the outer periphe of the drum are arranged slides g, whic may advanta eously consist of two-armed fiat levers t, he d by s rin ressure against thescrewed on plate ll iese slides are dovetailed at one extremity, 13, while the other end is formed with a bore s and these borings register with corresponding borings in the drumring 6. The drum is surrounded of. its 11nddle part with a hollow ring if of semicircular the accompanying drawings, in

owe in vertical cross-section, and the-outer end of the hub e V is surrounded by ehollow ring 1 In he ring it a, fork m is mounted in such a manner to be laterally displeoesble on a bolt 0, entoring longitud nnl slots n in the arms of the fort: and passing through the hol ow casing. fork carries on its host portion a lug n pro sided with a screwthreaded through which e screw-spindle g passes. This spindle rents in suitable llneliugs in the lr iow if the spindle is iotnted by means of the hamhwhcel r", the forl is dis plscedeither to the right or lef t hand, and as the fork is arranged so that it may ensue into contact with the druid-slides g tho-so latter will also be displaced either to thorlght or left by which means either the b ring '8 0f the slide is caused to register wile n correiponding boring m of-the plate it said of the rum-rice; c or to close the boring w.

The ii: =tcrial to be treated is sdmitte through lie pipe 3; and the hollow hub f into i the drum, owing to the rotation of which the solid constituents were forced under the inopened b moving the fork m during the operetio'n o the machine onto the inner face of the hollow ring it, from which they my be iluence of centrifugal force into theonter; part of the drum in the known man; :1, thence they pass when the slides 9 have been ters Patent of the United States, ls-- rated hubs eff 1. Centrifugal apparatus mounted upon a horizontal shaft, and more particularly ada ted for starch manufacture characterize by two hollow conical halves c, b fitted to ether at an-oblique angle and fixed on the 80 id driving-shaft d b means of two perfo of ifierent diameters of which the hub f serves for the supply of the material to be treated, while the other hub e surrounded by a hollow ring I serves for the discharge of the separated water substantially as described.

2. In a centrifugal a paratus, a horizontal shaft, hollow conical s iells fitted together at an oblique angle, perforated hubs of different diameters for securing said shells to said shaft, one of said hubs servin for the supply of the material to be treate and the ot er serving for the discharge, slides for controlling the discharge, automatic means for opening and closing the same and means for receiving the discharged material.

3. In a centrifugal apparatus, the combination of hollow conical shells fitted together at an angle and mounted on a shaft, a discharge-opening from said shaft adjacent said shaft, discharge-o enings at the periphery of said she ls, slides or controlling said peripheral openings, a casing surrounding said shells and in which the same rotate, a casing surrounding said first-mentioned openin and means or automatically controlling sai peripheral openings whereby the same are 0 ened and closed during the rotation of the s iells.

In testimony whereof I have hereunto set my hand, in presence of two subscribing witnesses, this 25th day of June, 1904.
