MATVEI K. MUGHIN, OF RIGrA, RUSSIA.

CENTRIFUGAL MACHINE.

SPECIFICATION forming part of Letters Patent No. 235,797, dated December 21, 1880.

Application :ned July 2o, 1880.

To all lwhom t may concern:

Be it known that I, MA'rvEI KosMr'rcH MUOHIN, a subject ofthe Emperor of Russia, and residing in Riga, Russia, have invented certain ImprovementsinCentrifugalMachines, of which the f'ollowing is a specification.

My invention relates to certain improvements in the construction of centrifugal machines for washing, soaking, rinsing, or drying fibrous materials, and other purposes, as more fully described hereinafter, reference being had to the accompanying drawings, in which- Figure lis a vertical section of my improved centrifugal machine, and Fig. 2 a front view.

A is the outer cylindrical casing bolted to the uprights of the frame, and through the center of this casing passes the vertical shaft B, adapted at its lower end to a step or bearing in one of the cross-bars of the frame, and having its upper end adapted to a similar bearing in an upper cross-piece. To this vertical shaft is secured the inner perforated drum, D, havA ing a central perforated cylinder or tube, F, around the shaft B, while to the bottom of the drum D is secured the Archimedean screw C, communicating` at its upper end with the interior of the tube F and opening at its lower end into the space within the lower part of the casing A. This part of the casing is preferably provided with a perforated ooring, and below this is a well, N, having an out-letpipe, Q, while above the partition are preferably arranged aseries of radial partitions, P, to prevent the shaft, screw, and drum from causing by their rotation the swirling of the water introduced into the casing.

Around the shaft B, at the part where it passes through the bottom of the casing, is arranged a tube, E, which is secured to the casing and projects some distance upward in the casing within the screw and above the level of the water when the casing is filled with the usual quantity, so that the outer casing needs no stuffing-box or bearingfor the rotat- (No model.)

ing shaft carrying the drum. This shaft may be driven in any manner that may be found convenient. In the drawings I have shown it as driven from a hand-wheel, L, provided with a handle, M, and having a belt passing overa pulley, K, on the shaft J, the latter carrying a grooved friction-wheel, G, gearing into a corresponding wheel, H, on the shaft B.

1f desired, the outer casing may be made double, so that it may be heated with steam or by other means.

This machine may be used for washin g, rinsing, soaking, or lixiviating brous materials, and when the proper supply of liquid has been pouredinto the casing and the materials placed in the drum the machine is setin motion, so that as the drum rotates the screw G will cause the water to ascend and by the centrifugal force pass through the goods and the perforations ofthe drum, to be again drawn up by the screw. When the washing, rinsing, soaking., or lixiviating is completed the shaft B is turned in the opposite direction, so that the screw C will not draw up the liquid, and the materials contained in the drum D will thus be dried by the centrifugal action.

I claim as my inventionl. The combination of the stationary easing adapted to contain liquid, and having a central tube, E, with the shaft B, passing through said tube and carrying the drum and Archimedean screwCattached thereto, all substantially as described.

2. The combination of the shaft and rotary drum with the stationary 'casing provided with radial partitions P in its lower part7 as and for the purpose specified. 1

In testimony whereof I have signed my name to this specification in the presence of two sub scribin g witnesses.
