Granted: 1900-08-18
Abstract: 18,551. Drysdale, B., and Webb & Son, C. Sept. 14. Brakes; clutches ; chain-wheels; ratchet gearing. -Relates to a combined free-wheel and backpedalling brake clutch and to brake attachments for cycle and other wheels &c. On to the sprocketwheel end of the hub H, Fig. 8, is screwed a ring or collar A, Figs. 2 and 7, having ratchet teeth a<1> on the larger part a<2> of its periphery, on which is also loosely mounted the chain-wheel S. The teeth a<1> fit in the interior of the wheel S, in which are also arranged pawls P, so that when the wheel S is driven in the direction of the arrow z, Fig. 2. one or another of the pawls P engages with one of the teeth a<1>, thus driving the cycle forwards, but when the rider ceases pedalling, the pawls slide over the teeth a<1>, thus allowing the machine to run forwards while the feet of the rider remain stationary on the pedals. A cap or cover s<3>, Fig. 4, . is fitted into the flange s', Fig. 2, of the wheel S ; on the outer face of this cover are pivoted pawls B, Fig. 4, which engage with ratchet teeth d<1> on the collar D, which is mounted on the reduced end of the collar A, Fig. 7, against the shoulder a<3>, so that when the rider back-pedals, one of the pawls B engages with one of the teeth d<1>, thus turning the ratchet D backwards so as to actuate a rim brake. This is effected as follows :-Fitting over the ring D is a cover E, having on it a projection e<1>. to which is fixed a connecting-rod F, Fig. 8, by which the brake is actuated. The other end of the rod F is arranged to act upon a crosshead M, in which is pivoted a connecting-rod N, the lower end of which is cnnnected to a flexible hanger R suspended over the wheel W. At the lower end of the hanger R, and projecting inwards, are slippers or shoes r<1>, in which the brake-blocks r<2> are held. The flexible hanger R is also made to engage with the edges of guides T fixed on the back stays K, so as to guide the hanger R in its movements. A spring f<1> holds the brake in, and returns it to, its normal position. The pawls B, Fig. 4, may be pivoted to the collar D, and the ratchet teeth d' be fixed to or formed on the outer face of the wheel S. The invention may be applied to sprocket-wheels of the construction described in Specification No. 16,698, A.D. 1897.

Title: Improvements in the Manufacture of POrtland Cement.
Inventor: GIBB ALLAN
Filed: 1900-08-30
Granted: 1901-07-06
Abstract: 15,432. Gibb, A. Aug. 30. Cements. - Portland cement is prepared by fusing the constituent materials in a furnace of the kind described in Specification No. 11,301, A.D. 1900, [Abridgment Class Furnaces &c.]. In order to lender the materials fusible without using a smaller proportion of lime than the requisite 60 per cent., peroxide of iron is substituted wholly or in part for the clay or shale usually employed. The furnace flame should be an oxidizing rather than a reducing one. Fusibility may also be ensured by substituting baryta, as carbonate or silicate &c., for part of the lime. Suitable materials for the production of cement by this process are sandstone or sand, limestone or chalk, and the residue remaining after extracting copper from burnt pyrites, known as purple ore ; or the peroxide of iron may be added as burnt ironstone or as haematite. Clay may also be added. The materials should not be powdered, but should be moistened and formed into lumps of about three inches diameter. The melted product is granulated in water, drained, and dried, the waste heat from the furnace serving for that purpose. The granulated material is then ground to form cement.
