PATENT OFFICE CIE!.'RJSLIAN' MEYER, 0F WYOMISSING, PENNSYLVANIA, ASSIGNOR T0 TEXTILE MA- CHIN'E WORKS, OF WYOMISSING, PENNSYLVANIA, A- CORPORATION OF PENNSYL- VAN IA- CENTRIFUGAL MACHINE Application filed December 21, 1929. Serial No. 415,726.
` This invention relates to centrifugal machines, and more particularly to an improved mounting or support for the gyrating unit of such machines.
The primary object of my invention is to provide, in combination with mounting or supportingm'eans for the gyrating unit of a centrifugal machine permitting bodily move-v ments laterally of its static axis to positions in substantial lparallelism therewith, of separate means for constantly urging the unit towards alignment with its static axis when deviating therefrom during operation.
` The inventioncomprises mounting means incorporating the novel elements, features of construction and arrangement of parts 1n operative relationship, as herein exemplified inl connection with a centrifugal drying machine of the type disclosed in my copendmg application, Serial No. 72,173, filed Novem-v A ber 3o, 1925.
' Other objects and attendant advantages of the invention will become more readily apparent from the following detailed description of one embodiment thereof, reference beingy had to the accompanying drawing in which- Theiigure is a vertical view of a centrifugal drying machine, partly in section and partly in full, and having my invention ap- The present invention relates generally to the subject matter covered in my copending patent application mentioned, and pertains particularly to improved mounting means for the gyrating unit of a centrifugal machine such as disclosed therein.
Referring to the drawing, the gyrating unit, in the present instance, generally comprises a vertical shaft 1, which is driven by a motor 2 connected to its lower end, anda container 3 rockably mounted on its upper end. A housing 4 encloses the shaft 1 and carries auxiliary operating parts.
As more fully explained in my copending application, the gyrating unit, during operation, tends to move bodily to constantly varying lateral positions in substantial parallelism with its static or normal axis, -such movespring arrangement 7 comprising a circular series of coiled springs having their converging-upper ends secured to a universal joint '8 at the bottom center of the motor housing 9, and their uniformly diverging lower ends secured to a frame member l0, which springs prevent excessive lateral play, and constantly urge the unit towards alignment with its static axis during operation.
The proper restraining action on the unit,
influential in maintaining machine stabilization at various operating speeds, may be obtained by nice adjustments afforded by nuts l1 on spring connected bolts 12. Of course, the" mounting means for gyratlng units herein shown and described may be modified in various ways without departing from the invention set forth, it is therefore to be understood that the same is not limited to the precise construction and arrangement of parts shown, but that such changes and alterations may be made as fairly come within the scope of the appended claim.
-In combination with a centrifugal machine frame and a rotary unit comprising a vertical container-supporting shaft and a motorhousing on said shaft; frame-supported mounting means for said rotary unit arranged to permit lateral bodily movement thereof and means tending to maintain said rotary unit in normal vertical position comprising a circular series of coiled springs having converging upper ends centrally connected by a universal joint to the base portion of said unit and uniformly diverging lower ends connected to said frame.
In testimony whereof I aiiix my signature.
