Patent GB-189809629-A (GB)
Title: The Manufacture of an Improved Detachable Cover for Pneumatic Tyres.
Inventor: CALDWELL THOMAS
Filed: 1898-04-26
Granted: 1899-04-26
Abstract: 9629. Caldwell, T., and Caldwell, W. April 26. Wrappers or detachable covers for pneumatic tyres. The cover will firmly hold on to any concave wheel rim. The textile fabric employed is formed somewhat V-shaped or U-shaped in crosssection, and is curved, as to its length, to correspond with the radius of the tyre to be made, such fabric being produced preferably in the manner described in Specification No. 9631, A.D. 1898. This fabric is stretched on an expanding mandrel so as to render it circumferentially inextensible, and while stretched it may be treated with water or mercerizing - liquids. A strip of the proper length is then wound round a collapsable mandrel of the same size as the finished tyre, and is treated with rubber solution and with a layer of rubber. When the cover is dry, it is released by collapsing the mandrel. The same procedure may be adapted for producing slipping-preventing strips, or, according to the Provisional Specification, covers for protecting tyres during transit or storage. The expanding mandrel, shown in Fig. 5, comprises four arms a along which slide radial rods b operated by screwing the nuts d. The rods b carry four circular quadrants e, which can thus be moved radially, the spaces between each pair being bridged over by hinged pieces f. In the collapsable mandrel shown in Fig. 6, there are four shaped pieces A, n, o which are held in the same plane by two side boards i secured together by bolts and nuts k. When the cover is finished, the nuts k are slackened, whereby the board i and the part n can be successively withdrawn. The mandrel is then collapsed by bringing the two parts h, h<1> slightly nearer together, this being allowed by the shape of the part o and by two grooves in the parts h, h<1> through which the securing-bolts pass.

Abstract: 4355. Challis, C. E. March 7. Domestic &c. filters; filtering-media; filters, aÙrating. - Relates to the manufacture of an artificial stone suitable for use as a filtering- medium and for other purposes. The stone is composed of pulverized flint, feldspar, sand, corundum, or other silicious substance, together with china clay or stone, alumina, or other clay, and sometimes bone or flint glass. Silicate of soda, borax, lead salts, nitre, &c. are added to constitute a flux when the moulded blocks are fired. Cobalt salts &c. may be employed as colouring-materials.
