Abstract: 15,751. Habild, C., and Jungnickel, M. Aug. 1. Bevelling glass. The spectacle &c. glass a is clamped between the ends of two spindles B. B<1>, pressed up by springs R<1>, R<2> and mounted in a frame C which is pivoted at C<1> upon a carriage H capable of turning on the top of a compound sliderest. The spindles are driven by spur-wheels from the spindle F, which is supported on the carriage H and is connected by belting through a countershaft to the main shaft of the machine ; they carry former discs R of the required elliptical shape, which rotate between fixed extensions T and springs V on the carriage H, so that the frame C is caused to rock on its pivots. The carriage may be set at the angle required to produce the desired bevel, by means of a spring catch H<2> engaging with a divided quadrant on the top slide, and it may be set to bevel either side. The apparatus is advanced to the grinding-disc Q by the screw L operated by worm gearing ; its movement is limited by a stop N. Another screw W serves to move the apparatus parallel to the axis of the grinding-disc. The grinding-disc has a slow axial reciprocating motion imparted to it by a cam Z working between collars on its shaft and driven by worm gearing. The spindle B' is drawn back, in order to change the glass, by a handlever S.

Granted: 1900-07-21
Abstract: 18,954. Imray, O., [Farbwerke vorm. Meister, Lucius, & Br³ning]. Sept. 20. Dyes, artificial.-Dyes, dyeing cotton red-violet shades which become black when treated with metallic salts, are produced by the action of an alkaline sulphide and zinc chloride, with or without ammoniacal salts, upon naphthazarin. For example, a mixture of naphthazarin, sodium sulphide, sulphur, zinc chloride, and water is gradually evaporated to dryness, and then heated to 160‹-180‹ C. until the colour ceases to increase in intensity. The product is dissolved in water, filtered, and evaporated to dryness. In another example, salammoniac is also added to the mixture. The dyes obtained when ammonium salts are used yield more violet shades on cotton.

Granted: 1901-01-03
Abstract: 189. Desprez, C., and Duthuit, G. L. Jan. 3. Pulleys, expanding. The pulley consists of a pair of discs b, formed with curved slots c and secured to the shaft a, a pair of discs d secured together and formed with straight slots e, and rods f, corresponding in number to the slots in the discs and fitted with segmental shoes h which form the driving-surface. The rods pass through the slots in both pairs of discs, and the diameter of the pulley is determined by the angular position of one pair in relation to the other. One of the discs d is formed with a toothed segment x, which gears with a pinion v on a spindle u ; upon the inner end of the spindle, is a pinion t in gear with a rack i, the stem of which fits into and is caused to move to and fro with a screwed sleeve k seated in the hollow shaft a. Mounted on ball bearings on the end of the shaft is a nut m, which engages the screwed sleeve and may be rotated in one direction or the other by means of a chain or otherwise. The nuts of two pulleys of a variable-speed gear may be geared together. The gaps, which exist between the segments when the pulley is expanded, may, as shown in Figs. 3, 5, and 6, be bridged by intermediate pieces h<2>; these pieces slide in grooves in the discs d, and are formed with wings h<1> which engage in recesses in the segments h.

Title: Improvements in or relating to the Burning of Liquid Hydrocarbons, Gas and the like.
Filed: 1900-03-08
Granted: 1901-02-09
Abstract: 4448. Clarkson, T., and Clarkson and Capel Steam Car Syndicate. March 8. Vapour and gas burners.-Relates to vaporizers or gas generators for producing vapour or gas from liquid fuel, which may be heated by the combustion of a portion of the vapour generated. The main portion of the vapour or gas is conducted to an independent burner or installation of burners for heating purposes. In the arrangement shown, the vaporizer or generator consists of three coils or zig-zag sections disposed so as to form a continuous conduit. The fuel is subjected to a preliminary heating in the upper zig-zag section d, whence it passes to a coil d<2> surrounding the burner G, being finally vaporized in the zig-zag section d<3>. The burner is of the kind described in Specification No. 18,679, A.D. 1898. The supply of vapour to it is controlled by an automatic regulator, consisting of two tubes of different expansibility through which the heated liquid fuel or vapour is passed, these tubes being connected up between two portions of the vaporizing-section d'. This regulator is of the kind described in Specification No. 5775, A.D. 1899, [Abridgment Class Furnaces &c.]. At starting, the burner is supplied with vapour from an independent vaporizer heated by the flame of an ignited wick over which a blast of air from a hand-operated fan is directed, as described in Specification No. 18,146, A.D. 1899. The supply of liquid fuel to the main vaporizer before the latter is sufficiently heated may be prevented by a fusible looking device of the kind described in Specification No. 4447, A.D. 1900. The sections of the vaporizer may be variously arranged, and they may all be in the form of coils, single or multiple, concentric or otherwise. The preliminary heating-section may also be arranged in a separate part, of the casing, which is then of twin form.
