CENTBIFUGAL EXTRACTR.

Specification of Letters Patent.

Patented Apr. 28, 1914.

Application alec February is, 1911. smal no. 608,937.

To all whom may concern; Y

Be it known that I, EDWARD F. POLAND,

residing at Boston, in the, county of Suffolk are connected.

v low step and State of Massachusetts, have invented yan Improvement in Centrifugal Extractors,

of which the following is a specification.

This invention relates to centrifugal extractors, and has for its object to provide anl extractor with improved electrcally-op erated means to operate it.-

In accordance with this'invention an electric motor is. arranged in Vertical position with its shaft constructed andarranged to serve as the revolving spindle of the extractor, and a universal stepV 'bearing arranged on a base is provided for the lower ends of said shaft and the motor case, and yielding means are connected with the base and lower end portion of the motor case to hold the motor in vertical position and prevent its case from revolving, which ermits gyratory movement of the shaft an correspending limited oscillations in all direc- The lower end ofthe spindle 12 enters or is contained ina cylindrical socket 14, arranged inV and extended diametrically through a spherical supportl, which support is provided with a .flange 16 for attaching it to the lower end of the motor-case 13. Said socket 14 has a flange 17 at its upper end which lrests on a seat provided at the top of the spherical-support and has a small hole at the bottom. Said s herical support rests in a spherically forme recess in a hol- 18, arranged on a base 19, the lower ends o said support and socket being exposed withinthe hollow step at the bottom of the recess. Said spherical-support, constructed and arranged'v as shown, provides for gyratory movement of the vertical spindle, and also serves as a support for the moy tor-case,l to permit oscillatlons of said case in all directions to correspond with the gyratory movement of the spindle.

To hold the motor-case from revolving and also to admit of oscillations thereof, corresponding to the gyrationfof the spindle, and to hold the motor-shaft 12 in vertical p os1t1on, means are arranged at one or more sides of the motor-case, which, as shown in the figure consists of an upright 4stub-shaft 20 havlng its upper end free to slide in a bushing 21, arranged in an arm 22, attached to the motor-case, said stub-shaft having its lower end formed with a horizontal, annular flange 23, which is placed between substantially constructed rubber rings 24 and 25,

which are held securely in a box comprising a bottom part 26 adapted to be secured to the base, and a top part 27 adapted to be detachably connected with the bottom part.

In operation, as the current isturned on the motor shaft 12 revolves, carrying with it the receptacle, and gyratory movement' of said shaft is permitted by the universal step-bearing, and corresponding oscillations of the motor-case likewise permitted, and said case .is held against rotation and the spindle held in vertical position by` the stub-shaft, which is yieldingly supported, 'and slidably connected.

The electric-motor is inclosed in a case to prevent the .water from coming in contact with it, but to more fully protect it a shield 30 is attached to its case, or may be otherwise supported, which is arranged beneath the receptacle 10,1 and above the motor.

In an electrically operated centrifugal extractor, the combination of a receptacle, an electric-motor arranged in vertical position, to the upper end of the shaft vof which mot-or said receptacle is secured, aspherical-boss detachably connected to the lower end or' the motor-'casehaving a center-hole through it, a stationarily supported spherical step-bearing for said boss, a flanged socket contained in the center hole in the boss which extends below the boss a'nd receives the lower end of the motor-shaft whereby the motor-case is caused to oscillate to correspond with the gyrations of said shaft, one or more arms rigidly attached to the lower end portion of the motor-case and radially extended therefrom, each arm having a vertical hole through its outer end-portions, a sleeve arranged in said hole, an upright shaft arranged in said `sleeve n parallel relation with the motor shaft and a yielding'elementj name to this specification, in the .presence of connected with the lower end of said uptwo subscribing witnesses.' A right shaft which admits ofan osf'zillatingv EDWARD FJPOLAND. movement of said shaft in all directions, Witnesses:

6 substantially as described. H. B. DAvIs,

" In testimony whereof, Ihave signed my B. J. Nom.
