UNITED STATES PATENT OFFICE.
WILLIAM EVERETT JOHNSGN, OF NEW YORK, N. Y.
CENTRIFUGAL EXTRACTOR.
SPECIFICATION forming part of Letters Patent N o. 486,876, dated November 29, 1892. Application filed January 20, 1892 Serial No. 418.624. (No model.)
To all whom it may concern:
Be it known that I, WILLIAM -EvERErT JOHNSON, a citizen of the United States, residing at New York, in the county and State of New York, have invented a new and useful Centrifugal Extractor, of which the following is a full, clear, and exact specification.
My invention relates to an improved centrifugal extractor; and it consists in constructing the machine in the novel manner herein set forth.
The object of my invention is to facilitate the easy starting of the machine and to reduce almost if not entirely, when starting, the vibration of the shaft, which carries at its upper end the basket.
My invention is illustrated by the accompanying drawings, in which- Figure l is a vertical part-sectional elevation on the line l l, Fig. 2, of my improved centrifugal extractor. Fig. 2 is a part-sectional plan view of Fig. l on the line 2 2.
A is an exterior casing having a suitable opening C at the top. The center of the lower part of the casing is preferably slightly raised, so as to form around it the gutter B. The casing A is supported on hollow posts D D, which are preferably fitted to the casing at a point'where the gutter B is formed. (See Fig. 1.) Perforations are made in the lower part of the casing A directly over the hollow posts D D, so that any liquid contained in the casing will follow the gutter B and run down through `the posts D D and out. Near the center of the raised portion in the bottom of the casing a hole E is formed. Through this hole a shaft F passes. This shaft F has a suitable bearing G in the base H of the machine. At the upper end of this shaft F, which extends slightly into the casing A, is fastened a supporting-frame, preferably consisting of arms I I, which curve upward and hold the support J. Within this support a ring or gimbal K moves freely on its pivoted bearings L L, said bearings being supported at or near the top of two opposite arms I I or at any suitable point in the ring J, which is supported by the arms I I. Within the ring K is a perforated basket N, turning freely on its pivoted bearings M M, hung at right angles to the bearings of the ring K. The axis M M of the basket N is preferably slightly above the center, so that it will hangin an upright position. The basket N is preferably about spherical in shape with an opening at the top. To the shaft F is fastened a pulley O, around which runs a belt P.
In operation wet clothes or the like are thrown into vthe basket N through the opening C in the outer casing A and the hole in the t-op of the basket. Wet clothes immediately finds a center directly over the shaft F by means of the gimbalbearings M M L L, balancing perfectly and equalizing the centrifugal forces when rotated. The shaft is then rotated by means of the belt P running round the pulley O until such a speed is attained as will by centrifugal force throw the liquid contained in the clothes out through the perforations in thebasket into the casing A, from whence it runs down v and out through the pipes D D. The Value of this invention can be appreciated by reference to the centrifugal extractors (or drying-machines, as they are sometimes called) now in use. All sorts of yielding bearings for the shaft F have been contrived, so that if the weight of the load carried by the basket N is off the center the shaft will take any position to allow the unequal weight to ap proach a center and facilitate starting the machine.
Experience demonstrates that itis almost impossible to start an unevenly-loaded basket to revolving if it is supported and turned by a shaft having non-yielding bearings, even if the weight be .no more than a wet sheet thrown into one side of the basket.
My invention does away with the necessity of a yielding bearing for the shaft F,for the instant any weight is placed within the basket it seeks a center directly over the center of the shaft F, and the mechanism may be easily and quickly rotated without any perceptible vibration or yielding of the shaft.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, isn
l. In a centrifugal machine, a basket pivotally suspended in a ring from which said basket depends, the said ring being pivotally supported in a frame carried by a shaft, substantially as described.
2. The combination, in a centrifugal ex- The Weight of these IOO tractor, of a basket A, mounted upon suitable pivots Within lthe 'ring K, said ring being pivotally mounted at right angles to the axis of the basket in support I with a vertical shaft F, substantially as described.
3. The combination, in a centrifugal extractor, of the basket A and its pivot-bearing M M, supported in the ring K, said ringbeing supported by its pivots L L, which bear in the support J carried by the arms I I, with the shaft F and mechanism for rotating the same, substantially as and for the purpose shown and described.
