Application filed July 2,
This invention relates to centrifugal extractors such .as are used for extracting the moisture, water or cleaning fluids from fabrics or clothing during treatment thereof in laundries, dry cleaning plants, textile mills or the like.
The object of the invention is to provide y an improved extractor, and more particularly an extractor of the over driven type, in which therotating spindle and basket are electrically driven by a motor, the armature or rotor of which is fast with the spindle and the eld frame of which is mounted upon a part which isrelatively stationary as regards the spindle, the arrangement being such as to simplify the bearing construction and safeguard the motor from the bad eli'ects of shock, jar and vibration due to unbalanced loads.
Further objects of the invention are in part obvious and in part will appear more in detail hereinafter.
In the drawings Fig. 1 represents a front elevation of an extractor embodying the invention; and Fig. 2 is a detail section on a larger scale, on the line 2 2, Fig. 1.
The extractor shown in the drawings comprises a relatively stationary frame including a base 1 resting upon the floor or other support and upwardly extending members 2 connected at their upper ends to form a support for the basket and curb, as will appear. 3 represents the curb which is a hollow bowl shapedmember provided with upwardly extending arched supportingmembers 4 formed to provide a vertical guide and bearing 5 for the spindle 6 which supports the basket 7 having the usual perforated outer wall 8. In the bottom of the curb are located suitable bearing devices 9 for supporting and guiding the spindle 6.
The spindle 6 may also be guided'and supported in an intermediate bearing 11 carried by a cross-bridge 12 extending horlvzontally across between the upright members 4. carried by the curb.
With this arrangement the spindle and basket rotate in the curb member andthe basket and curb swing or oscillate together or as a unit about a point near the top of the frame, so as t0 enable the basket and curb by such motion to compensate for unbalanced loads and thereby producel a true spinning motion without shock or vibration.

1921. Serial No. 482,176.
The movable curbv memberl lis therefore ysuspended from'v the stationary-frame. member in any suit-able manner to provide tree swinging motion horizontally in all directions, such as by aI universal joint. In the arrangement shown the curbmember is hung and swings from front to rear upon a pivot pin 13 which in turn is carried by a member 14 pivoted to swing from right to left upon the pin 15 kcarried by the stationary frame. The basket and spindle are rotated by an electric motor which may be of any suitable form. `The drawings represent said m0- tor somewhat diagrammatically. It comprises a rotor or armature 16 attached to the basket spindle 6 n and turning .within the stator or field frame 17 which is supported by the cross-bridge 12 and is therefore staionary relative to the swinging curb mem- By supplying current to the motor the entire power etfect is converted into pure torque vupon the basket spindle and with absolutely no lateral pull such as would be exerted by the eiIect of a driving belt upon a pulley carried by the spindle. The normal tendency of the basket spindle is theretore to merely spin about the motor axis. In case the load in the basket is out oftrue balance the basket and curb members swing Ytogether or as a. unit to one side or the other to compensate for the unbalanced condition. This motion, however, carries both parts of the motor, to wit, the rotor and iield frame, with the swinging parts. As a result, the usual shock, jar and vibration of unbalanced loads are not communicated to the motor parts nor are they transmitted through such conical portion which usually covers the longfr bottom bearing of the basket spindle in the curb. The motor clearance is also maintained uniform. The use of an electric motor directly connected to the spindle also enables electric braking eii'ects to be employed, there- Also, the bearings for by doing away with the lateral or horizontal pushing eHect of a bra-ke shoe upon a pulley or drum carried by the spindle. That is to say, in the present arrangement the motor, if it is a. D. C. motor, will be braked by a dynamic braking effect and if an A. C. motor by reverse phase braking. Therefore, neither the driving nor the braking effects produce lateral or horizontal strains upon the spindle.
Vhat I claim is: f
An extractor, comprising curb and basket members arranged to swing together about a joint from which they are suspended, a basket spindle having three separated bearings, upper, lower, and intermediate,'in the curb member, the'basket being secured to the spindle between the lower, and inter'- Vmediate bearings, `and anelectric motorhaving a rotatable part'directlyV connected to said spindle between the upper and intermediate bearings for driving the spindle.
In' testimony whereofl I hereby affix my signature,
