`GSHLAJSE H. JANTZ,
To @ZZ whom z': may concern."
Be it known that Gusravn H. JANTZ, a citizen of the ilnited States, residing at lfvlyoming, in the county of Hamilton and State of hio, have invented certain new and useful 1improvements in VJringer Rolls for Clothes lNringers, of which the following is a specification.
`Wringer rolls heretofore constructed comprise a central shaft to which has been affixed, in suitable manner, a cylindrical body of 'resilient material, such as rubber, the ruboer having` in practice been laid around the shaft in layers, and then vulcanized, VVVringer rolls are usually provided with power transmitting means, for instance cog-wheels, at the respective ends thereof,
and with driving means, for instance a handjcranli, when the wringer is intended for manual operation, or with a suitable cog-gear or cog'gearswhen the wringer isr intended for power actuation, for instance in connection with a powerl washing machine.
The coating or covering of the wringer roll deteriorates in course of time, and when it has been desired to provide a new wringing surface, it has been found necessary for the user to purchase an entirely new roll, including the power imparting and the power transmitting means thereon, forrthe reason that, as heretofore constructed, the body of the resilient material or rubber has been permanently vulcanized to the shaft. Shafts of various lengths and with various propelling'y means thereon have heretofore been made by the different manufacturers of wringers, so that ithas been necessary heretofore for the user, if he desired to renewl his wringer roll, to obtain an entirely new roll and its attendant. driving and transmitting means, from the manufacturer' ot' the particular machine which he has been using. y
It is the object of my invention to so construct the wringer roll that the resilient surface is provided with a foundation, so
that the same may be renewed without the necessity of renewing the working parts connected therewith; further, to provide a' driving shaft comprising a plurality of sections and having the power transmitting means thereon, and a wringer roll, provided with a resilient wringing surface, having releasable connection with said sections;
further, to provide a wringer roll, com- @E TliYOlVIINGr, OHIO.

prising a shell having a resilient body thereon, and a driving shaft having releasable connection with said shellgand, further to provide a pluri-part shell, the parts of which are arranged to be connected and to receive the resilient body of the wringerroll thereover, and a shaft releasably received in the shell, so that the shells with the resilient'wringer-bodies thereon may be selectively placed upon and exchanged upon the shaft.
The invention consists in means for effect# ing these purposes, and in the novel construction, arrangements and combinations of the parts.
In the drawings:

The wringer frame is exemplified at 11, and may be of any suitable, usual or desired construction. A wringer roll 12 is arranged to -cooperate with a wringer'roll 13. The
' shaft of the wringer roll 12 is arranged to rotate in bearings 14 in the frame, and the shaft 15 of the wringer roll 13 is arranged to have bearings 16 coact therewith. The bearings 16 are arranged to slide in guideways 17 in the frame, pressure means being provided to exert pressure thereon for causing` pressure between the rolls when wringing the clothesl A spring 18 may be employed to exert this pressure, being shown adjustable by means of a screw 19, threaded l frame.
in a bearing 2O on the cross-*bar 2l of the I have exemplified my invention as applied to the wrino'er-roll l2. which is the driving wringer roll of the pair.` being, in practice the lower wringer-roll.
Cog-gears are fixed, as by pins 26. to the shaft of the driving wringer-roll and are arranged to mesh with. eog-gears 2T 'secured liX-edly7 as by pins 28., to the shaft of the driven wringer roll. Gear-covers 3l secured to the frame7 mayV he provided for the cog-wheels and extend over the ends of the resilient portions of the wringer rolls for protecting the same and the clothes which are being operated on.
The shaft of the driving wringer roll is provided with suitable driving means.
These driving means may he either power.
vdriven or manually operated. I have in Fig. l shown the same as power driven means', comprising a driving bevel-gear 36 which meshes with bevel-gears 37. 3S, normally loose apart. to the shaft of the driving wringer roll, which is extended for the pur pose. Collars fixed by pins 39 to the shafhhold the bevel-gears 3T. 38. in mesh with the bevel-gear 36. clutch-collar 40 has spline-connection el with said shaft and is arranged to be moved lengthwise into neutral position, or for engagement of one of the clutches 42, 4?, respectivel)v for atrest positioning of the wringer-rolls, or for Ydriving the Wringer rolls in either direction.
I have in Fig. 2 exemplifiedrthe shaft of the driving wringer roll provided with a crank-handle i6 of usual construction, secured to the shaft of the driving Wringer-roll by usual means, as by a screw-threaded connection i7 between the hub of the crankhandle and said shaft, and a nut i8 received over the threaded reduced end i9 of said thereon. or the securing means thereon for the 'crank-handle' when a crank-handle is employed.
In'my improved construction I mount the resilientclothes contacting portion of the wringer roll on a releasable foundation so that this releasable foundation with its resilient covering may be replaced by a freshV or new releasable foundation with its resil ientI covering Without the necessity of I'eplacement of the shaft, the cog-gears or the driving means.
Exemplifying such construction I provide a shell. This shell is preferablypl-uri-part, comprising the sections 5l 52. Each end of each shell-section has a section 53 of a bearing therein. The sections of the bearing at each end of the sleeve Ycoact to Vform a positioning means for the shaft. The shell-seo tions are at appoint intermediate of their i ends provided with cooperating bearing secinto the shell through opposite ends of the latterpand the proXimateends of the shaft-sections areprovided with parts which coact with the attaching means in the interior of the shell. The coacting parts of the The respective shaft-sections are 1" shaft-sections are shown as ends 6i, 62, re-j ceivedin the sockets, the walls of these ends coacting with the walls of the sockets for preventingl relative Vrotation between the shaft-sections and the shell. The socketsa when the shell-sections are assembled,V are exemplified as provided with fiat sides, the ends of the shaft-sections beingV provided with coacting flat sides, so as to form a tongue and socket connection between the shaft-sections and theshell.
In order to provide for ready assembling of the parts, the respective shell-sections are Y provided with coacting shoulders 64:, formed preferably by overlapping Vthe peripheral wall of one of the shell-sections with the rebe integral with the respective shell-sections.
Collars 7l are received over the ends of the shell-sectionsv when the latter Yhave'been assembled. The collars act to vpress the shell-V sections together. They may be secured to the shell-sections by suitable means,V for in- Y stance a pin 72 received through apertures in the collar and the respective shell-sections.V
The parts of the releasable wringer-roll thus far described, are preferably of metal, and form the foundation about which the .resilient body 74, for instance rubber, is received. lThe s hellwhen connected, has
therubber coating fixed thereto in any desired manner, as by providing the outer peripheral surface of the assembled shell between the collars with a binder coating, and arranging layers of rubber paste round about the latter, which rubber layers may coinprise body portion and an outer surface portion; rlhe shell with its coating `may then beplaced in a suitable mold, and the resilient materialv vulcanized in usual manner, for lixing the cylindrical resilient body upon the shell.- The collars serve as end walls for the 'rubber'cylindeig the latter being however, preferably of greater dia-ineter.
The shaft-sections may beassembled in the shell during assembliiigof` the latter, or
the shell may be secured to the shaft-sections after thevi'eleasable,wringer roll is completed.Y When the latter manner otassenbling is employed, the shaft-sections are insertedV lengthwise into the respective ends of the `assembledV shell, the inner ends of theshaft-sections being placed in coactive p relations with Athe inner bearing in the shell, 1tor forming the driving relation between them` and preferablypositioning the inner ends of theshaft-sections inall lateral directions in the shell. When this driving 1 relation is..eil"ected,V the portions of the shaft-sections which are in the outer bearings ill these bearings, so that the releasable wringer-roll iscentrally located on the shaft-sections. The pins 72,"which Vhave been previously removed are again passed through the collars 7l, the shell-sections, and the respective shaft-sections, for aiding in rotatively securing the shaft-sections and the releasable wringer roll together, and to prevent endwise movement between the shaft-sections and the releasable wringer roll. The coacting portions between the inner ends of the shaft-sections and the shell are such as to cause the axes of the shaftsect-ions and of the shell to be coincident.
When it is desired to renew the releasable wringer roll in my improved device, the pins 72 are removed, and the shaft-sections are withdrawn endwise out of the shell, a new releasable wringer-roll being substituted for the worn-out releasable wringerroll, the shaft-sections and the new releasable wringer-roll, being re-assembled in the manner hereinbefore described. In order to insure ready assembling of the parts, the inner end of the shaft-sections and the inner bearing of the shell are preferably provided with tapering ends, exemplified as the tapering ends 76 of the shaftsections and the outwardly tapering ends 77 of the walls of the sockets, either or both of which may be employed. In order to facilitate the release between the shaftsections and the shell I prefer that the reduced portions of the shaft-sections, or one of the same, shall be sutiiciently long to extend substantially through the length of the socket in Vthe interior of the shell, tor the purpose, if desired, that one of the shaftsections may be employed to drive the other f shown and described, having shown, de-
scribed and claimed the same in a oopending applioationfor Letters Patent of the vUnited States `on improvements in wringer rolls for clothes wringers, vSerial No. 380,-
