Title: A Continuously Variable Speed Gear.
Inventor: SHARP ARCHIBALD
Filed: 1900-12-11
Granted: 1901-11-30
Abstract: 22,574. Sharp, A. Dec. 11. Variable-speed gearing for transmitting rotary motion between two parallel axes, applicable for cycles &c. Consists of a drive-ring concentric with one of the axes, a wheel concentric with the other, and a number of equal drive-links each jointed at one end to the drive-ring and fitted at the other with ratchet blocks adapted to engage with the wheel. In order to vary the speed, the distance between the axes is varied, and means are provided for this purpose and for clamping the two axes together at any required distance. Figs. 7 and 8 show the application of the invention in connection with a bicycle in which the drive-ring D, secured to the hub B, has jointed to it the links L provided at their outer ends with ratchet shoes adapted to engage with a toothed surface on the inside of the chain-ring 1. The shoes are guided by pins which work in grooves g in the chainring and the closing-ring 4 ; they are each fitted with a spring S adapted to force it into engagement with the chain-ring as it approaches the position at which it takes up the drive. The axle B is flattened on opposite sides, and carries a number of washers which alternate with other, larger, washers fitted loosely in the ring b, upon which the chain-ring runs by ball bearings. The washers may be grooved to ensure gripping. The ring b and its washers are slotted to fit the flattened part of the axle, and may be moved vertically, to vary the distance between the axes, by means of a link 14 jointed to a bell-crank lever 13. The washers are pressed together, to lock the ring b in the desired position, by means of a lever 11, having a series of cams around its eye, which act against similar cams on a plate 12 which is prevented from rotating. The levers 11, 13 are coupled by Bowden transmission devices to operating-handles on the handle-bar of the bicycle. Springs 20 in telescopic cases 26, Figs. 10 and 11, normally press the levers so as to keep the friction washers pressed together, and to tend to draw the ring b downwards. Fig. 15 shows the arrangement for operating ; the hand-grip 44 may be turned on the handle-bar 41 ; it has connected to it a nut which fits over a screw 43, prevented from rotating, to the head of which the end of the Bowden wire 21 of the shifting-device is secured. The wire 22 of the lever 11 is secured to a lever 52, pivoted on the hand-grip, by means of a fork 53 ; this fork is coupled to a thimble 54, which has prongs projecting through slots in the flange of the nut and bearing upon the serrated face of the fixed plug 42, and thus serves to lock the band-grip in any desired position. A modified arrangement of friction shoe is shown in Fig. 17.

Patent GB-190117491-A (GB)
Title: Improvements in the Shape of Bottles and similar Vessels together with a New Method of Closing the same to Provide Indication of and Protection from the Fraudulent Re-use of such Bottles and Vessels
Inventor: REYNOLDS JOHN THOMAS
Filed: 1901-08-31
Granted: 1901-11-02
Abstract: 17,491. Reynolds, J. T., and Reynolds, J. H. Aug. 31. Bottles &c. ; stoppering; corking ; emptying bottles &c. ; refilling, preventing and detecting.-Relates to bottles and similar vessels which cannot be re-used without detection, the stoppering being effected so that, when a vessel is opened, a permanent indication is left within the vessel, to show that the closure has been broken. The neck of the bottle &c. is formed with a narrow bore A, and projects inwardly at C, where it is closed by a cork or stopper H, J of cork, rubber, or other suitable resilient material. The stopper may be about twice the diameter of the bore, and is preferably cut, as shown at G, Fig. 3, so that, when forced into the neck until the cut comes below the shoulder C, the lower portion J expands, as shown in Fig. 6, and cannot be again withdrawn. To prevent the part J from being accidently detached, a thread g may be passed through the stopper and knotted at each end. A tube K, Fig. 5, is preferably placed in the neck while the stopper is being inserted, to permit the escape of air from below the stopper ; or the air may be exhausted through the tube while the stopper is in the upper end of the neck. The stopper is forced inwards to open the vessel, and cannot be again withdrawn, as it is larger than the bore of the neck, while the narrow bore also prevents the insertion of a barbed or bent instrument. To prevent the use of a flexible cutting-instrument, the bottom of the vessel may be formed as shown (half-scale) in Fig. 1, the surfaces E being rounded from the apex D, so that they offer no resistance to the movement of the stopper. In the modified form shown in Fig. 2, the instrument cannot be forced into the groove F, which surrounds the coned part D<2>, E'. The vessel should be corked at the mouth in the usual way, the tube K being again employed to relieve the pressure between the cork and the stopper H.. To facilitate the discharge of the contents when the vessel has been opened, an air-inlet tube is inserted through the neck, the outer end of the tube being closed until its inner end reaches the bottom of the vessel. The outer end of the tube should be bent backwards outside the neck.

Title: Improvements in the Manufacture of Soluble Glass
Inventor: BRONN ISRAEL JEGOR
Filed: 1902-11-05
Granted: 1903-11-05
Abstract: 24,237. Bronn, I. J. Nov. 5. Potassium and sodium silicate. - Consists in making soluble glass by heating a crude mixture of sand and alkaline carbonates or sulphates in an electric resistance furnace of the kind described by Borchers, and subsequently adding substances containing carbon. When using alkaline carbonate, about 3 percent. of pounded coal briquette is added, which contains about 43 per cent. of carbon to facilitate the process, while excess of alkali salt must be avoided ; otherwise the material becomes too fluid, and runs off before the sand becomes completely dissolved. Excess of carbon must be avoided when employing the sulphates, and the current must be of such an intensity that a normal evolution of sulphur dioxide is obtained, as otherwise the formation of sulphide is facilitated. When sulphates are employed, the operation is cheapened by the addition of alkaline chlorides, especially when acid sulphates are used. In this case, the furnace is advantageously provided with a gas recuperating apparatus to collect the escaping acid vapours. The crude mixture is used in a granular form, and to obtain it thus it is wetted with a little tar, water, &c. and divided, after being thoroughly dried. A continuous, polyphase, or alternating current may be employed, as desired.
