Title: An Improved Method of Grinding Glass and Apparatus therefor.
Inventor: GOEHRING CHARLES LEWIS
Filed: 1902-07-05
Granted: 1903-02-12
Abstract: 15,003. Goehring, C. L., and Clause, W. L. July 5. Surfacing; bevelling glass. In the grinding of glass, the glass and the part of the grinding-roll &c. in operation are immersed in water to increase the output and decrease breakages. In the form of apparatus shown, which is particularly applicable for grinding flats or bevels on glates plates, the work is carried by a reciprocating table 25 having a tank 26 to hold the liquid in which the work is immersed. The grinding-rolls 5, 6, 7 are mounted in standards 4, and are of successive degrees of fineness. The finer rolls 6, 7 are driven by chain gearing from the rough roll 5, which is driven from the main shaft 10. Each roll is adjusted vertically by screws 12 actuated by crossshafts with hand-wheels 24, and each roll has a slight axial reciprocation imparted to it during grinding, the rolls being of sufficient length always to cover the width of the plate. The finest roll has also a slight reciprocation in the direction of movement of the table imparted to it by an eccentric on the driving-shaft through links 22 and lever 21. The work is prevented from moving longitudinally on the bed by clips, and is held down by spring-actuated presser-feet 33 and by weighted rollers 34, the end roller 34 having lifting-handles 37, by which it may be raised against the action of springs to release the work when finished. Water supply and waste pipes are provided to the tank, the supply; producing currents to clear away grit &c. while the work passes from one roll to the next. The grinding-stroke of the table is effected by a screw 39 and nut 44, Fig. 4, the screw being rotated by worm gearing 40 and fast and loose pulleys 41 from the driving-shaft. The nut is formed in halves, which can be drawn together or released by turning a rod 47 with cam surfaces 46 engaging similar surfaces on the halfnuts, the halves being pressed apart by springs 48. At the end of the grinding-stroke the rod 47 is rocked by a stop 53 on the bed engaging a projection 52 on a handle 51 on the rod. A quick return is obtained by rack-and-pinion gearing 58, driven through fast and loose belt pulleys 60 on a shaft 59 driven from the driving-shaft, the belt shifter being operated by a handle 74 or by a tappet on the table. The method of submerging the work in water may be applied to glass grinding generally, such as bevelling circular plates.

Title: Improvements in or relating to Diaphragm Valves and the like.
Inventor: FIMISTER THOMSON PAXTON
Filed: 1903-05-30
Granted: 1904-03-24
Abstract: 12,336. Fimister, T. P. May 30. Ball and float valves; diaphragm valves; mixing- valves; noise, preventing.-In a ball and float valve for an ordinary flushing-cistern, whereby the latter is filled without noise, a leather, thin-metal, or other flexible diaphragm 11 is rigidly held at its ends between flanges 20 of a valve casing 14, and normally has a seating against the end 17 of a supply pipe 12. Water enters a chamber 15, from the supply pipe 12 and, passing through a small hole 21 in a stud of metal or the like fixed in the diaphragm 11, fills a larger chamber 16 on the other side of the diaphragm, which thus closes the inlet. When the cistern is emptied, a falling float, acting through a lever 23, opens a valve 19, so that the water in the chamber 16, escapes through a relief passage 18 and a pipe 24 to the cistern. The pressure of the water in the chamber 16 on the diaphragm 11, falls more rapidly than can be compensated for by the fresh supply of water through the hole 21, so that the main water supply from the pipe 12 forces the diaphragm away from its seat, and escapes through a discharge pipe 25 to fill the cistern. Fig. 6 shows a similar form of valve adapted for the supply and delivery portion of a street fountain, the valve being opened by pushing a relief valve 19, against the force of a spring 22<a>, to allow the water in the chamber 16 to escape through a relief passage 24, which, in this case, leads into the discharge pipe 25. Fig. 7 shows the application of the device to a wash-hand basin, or bath, whereby hot or cold water may be separately or together admitted to the bath &c. by turning a plug 19<a>. The Provisional Specification also states that a rigid sliding disc, moving towards and away from the supply pipe 12, may be used instead of the flexible diaphragm 11.

Bottling.-Relates to an apparatus, for use in restaurants, bars, &c., for making and delivering aerated beverages such as " mineral waters," with or without the addition of fruit juices or essences, into bottles &c. The two liquids used in making the beverage and for the generation of the carbonic acid are delivered from two separate compartments a, b, Figs. 1 and 2, in the upper front part of the apparatus through a double cock d, and the essences &c. from a number of underlying drawers f through cocks f<1> The upper rear compartment c contains ice for cooling the liquids in the compartments a, b, and may be used as a freezing-chamber in the preparation of ice-cream or ice, the remaining drawer g being used as a rinsing- vessel or for holding tools &c. The plug and barrel of the cock d have each two separate passages communicating with the compartments a, b, as shown in Fig. 3. The passage l of the plug o is of circular section, but the passage m tapers from each end to the centre in the form of two truncated elliptical cones having the shorter axes of their bases parallel to the centre line of the plug. The arrangement is such that the passage k may be opened to the full extent of the central or constricted part of the passage m before the passages i, l are in line. By these means, any desired quantity of the liquid in the compartment b may be drawn off alone, or any desired proportion of the other liquid may be drawn off with the first liquid. It is stated that the proportions of the two liquids may be so regulated that the gas is generated only after a short interval of time, during which the bottle which received them may be closed.
