Specification of Letters Patent.

Application filed April 14,1906. Serial H0. 255,670.
Be it known that I, GEORGE WHEELHOUSE RoBINsoN, a member of the firm of Robinson Bros. Cork Growers, Limited, and a subject of the King of Great Britain, residing at Corredoura, Portalegre, in the Kingdom of For tugal, (whose postal address is Horton street, Halifax, in the county of York, England,) have invented new and useful Improvements entitled Improvements in Rollers for Washing, Wringing, Manglin and other Similar Machines, of which the ollowing is a specification. f
This invention relates to rollers of wash.- ing, wringing, mangling, and other similar mac es. v
The object of my invention is to construct said rollers of a material and in a manner that will be unaffected by the action of water or other moisture or torsional or peripheral friction, will give ood results under pressure, retain their straigIr easily cleaned, and greatly increase their durability. I
In the drawings, Figure 1 is a lon itudinal section through a roller constructe according to this invention, and Fig. 2 is a cross-section through the same.
In constructin my improved roller I form or manufacture filie same from slabs or disks of cork constructed or built u in a particular mannerthat is, each bloc is com osed of a number of solid cork slabs or dis or from layers of granulated cork or cork-dust. These cork slabs or disks or the layers of granulated cork or cork-dust, as the case may be, are subje Led to a series of greatpressures within a suitable hydraulic or the l1ke press and bound together or compressedinto a homogeneous whole.
In order to obtain a permanent and effectual adhesion of the several slabs, disks,
or layers aforesaid, Itreat the component parts as follows: In using slabs or disks of which I preferably construct my improved.
rollers I place two slabs within a suitablyshaped chamber or cylinder supported Within a suitable framework and subject them (by means of a hydraulic press) to a great pressure-say two or three thousand pounds to the square inch, more or less, as found suitable. The ram of the press is then raised and a third slabintroduced, the pressure again applied, theram a ain raised, a fourth slab introduced to the cy inder, pressure once more applied, and so on alternately adding block within t the desired length. Each pressure perma t and parallel surfaces, be
a slab and ap lying the pressure until the lie cylinder or chamber is of nently fixes or attaches the last-added slab or disk to the rest of the block.
When employing granulated cork or corkdust, a suitable quantity (preferably repre senting two subsequent layers) is laced within the pressure chamber or cylin er and pressure applied, as aforesaid, after which a regu lated uniform quantity or layer of loose material is added and pressure a plied alternately until the desired length of block is obtained. The slabs or disks, as well as the several layers of loose material, are by these alternate introductions and pressures bound or compressed into a solid block capable of being turned down into a roller for the purposes before described.
A is the roller, constructed of cork disks a, as hereinbefore set forth, and mounted on a shaft B between end plates 1). v
i The block upon being cut or turned down and made cylindrical presents a smooth and uniform periphery unaffected by Water, temperatures, varying degrees of moisture, dyes, or peripheral friction. Further, rollers of this construction are not liable to retain or exude dyes or other undesirable coloringmatter which previously they may have come in contact with.
In rollers for domestic or laundry purposes, es ecially for mangling, I ropose to fill up t e natural recesses or epressions .which occur in the cork by treating their peripheral surfaces with a solution or paste composed of materials or substances impervious to and unaffected by hot Water, such as alcohol and shellac in equal parts, calcium phosphate, and boiled linseed-oil, the shellac to be dissolved inthe alcohol and mixed with the calcium phosphate and linseed-oil until they form a paste, or in place of this preparation I may employ animal glue and add two per cent. of otassium bichromate. After using either of liiiese pastes for the aforesaid purpose and exposing the roller so treated to bright sunlight for one to six months the said fillingbecomes impervious to hot water. I-
