Patent GB-189807467-A (GB)
Title: Improved Means Applicable for Use in Operating Electrically Illuminated Signs, Advertising Media or the like.
Inventor: BELL WILLIAM THOMSON
Filed: 1898-03-28
Granted: 1899-03-28
Abstract: 7467. Bell, W. T. March 28. Advertising; signs.-Incandescent lamps, arranged on an advertisement or signboard, are lighted to represent the advertisement or sign by means of apparatus such as shown in Figs. 1 and 2. The drum A, which is preferably of rectangular section, and is provided with conducting face-plates Ax, is covered with jacquard cards K arranged on a flexible carrier. The drum is reciprocated by means of a cam E towards and from spring contact-bars B, connected with the lamp wires, and thus certain lamps, determined by the jacquard, will be lighted while the front plate Ax of the drum abuts against the contacts B. On withdrawing the drum from the contacts, it is rotated a quarter turn to bring the next face into operation. To prevent sparking, a cut-out is used which breaks the circuit slightly before the retreat of the cylinder A from the contacts B. This consists of a disc or cam l of non-conducting material, provided with flanges, on which are mounted rings l<2>, l<3>, placed in metallic connection with one another by a strip l<4>. Brushes M, M<1> of the main circuit make contact with these rings, and, the ring l<2> being formed with a gap, the circuit is thus broken.
Patent GB-189808068-A (GB)
Title: Improvements in Time Stamps.
Inventor: ENTWISLE JOSHUA
Filed: 1898-04-05
Granted: 1898-06-11
Abstract: 8068. Entwisle, J., [Tuerk, A.]. April 5. Date and time printing stamps.- The registering or printing wheels G, of which only one is shown in Fig. 2, are loosely mounted upon a shaft Z placed within a verticallymovable frame M, which is normally held in the raised position by springs N. A shaft E, mounted within the frame M, carries a series of levers D, the inner ends of which are adapted to bear against the shoulders of stepped or other cams on a shaft R, and the opposite ends carry pins d which engage with slots g formed eccentrically in the wheels G. A frame F mounted on the shaft E has two arms f carrying a transverse bar f<1>, two arms f<2> passing above a pin k in the lower end of a plunger K, and a transverse bar formed with teeth f<3> adapted to enter the spaces 1, 2, &c. in the upper parts of the wheels G. When the plunger K is forced downwards by an operator, a spring L forces the frame F downwards, and the levers D are oscillated as far as the step cams permit so as to rotate the wheels G ; a collar on the plunger next forces the frame M downwards so as to cause the teeth f<3> to lock the wheels G and to force the wheels against a pad O. Beneath the wheels G is an inking-ribbon P wrapped upon rollers. The extent of movement of the pins d is limited by means of the stepped cams, which are driven at fixed relative rates by means of a special arrangement of toothed gearing, and discs, carrying one tooth or two diametrically-opposite teeth, mounted upon the shafts R, S. There are six cams, mounted on the shaft R, corresponding to six printing-wheels, which respectively print tens of days, units of days, hours, tens of minutes, units of minutes, and a.m. or p.m. A clock of ordinary construction drives the shaft R by means of toothed gearing so proportioned that the shaft rotates once in ten minutes. The clock mechanism is preferably so constructed that the gearing will remain at rest for an interval, such as a minute, and will then move so as to indicate such interval. This control of the clock is effected by an auxiliary train of mechanism comprising a ratchet-wheel 14 fixed to a shaft 17 and engaging with a pawl actuated by a pivoted lever 13, which is periodically oscillated by a cam 12. An escapement mechanism 9, 10, 11 controls the cam 12, so that the latter revolves once in a minute, and thereby allows the wheel 14 to advance through the space between two adjacent teeth ; during this movement the minute-hand of the clock advances. The shaft 17, when released, is rotated by means of the main wheel 5 and gearing 20, 21, and at the same time a spring is wound up ; this spring is fixed at one end to the shaft 17, and at the other end to a toothed wheel loosely mounted on the shaft 17 and gearing with a toothed wheel 7, which drives the escapement mechanism. The printing- wheels for the years and months are preferably set by hand.

Granted: 1899-02-18
Abstract: 8386. Klopp, G. O. H. April 9. Lift valves.-Relates to a valve in which the liquid supply is cut off by a hard ball D when the spindle C is raised. A washer F is held in place by a clamping - ring G held down by a stuffing-box L engaging the screwed spindle I the downward motion of which is limited by a ring K. When depressed, the ball D rests in a hollow screwed cap E. If the washer F be removed, for renewal, the ball seats itself against the casing. In a modification, the valve is made self-closing by giving the spindle I a quick screwthread, and a flange on the spindle U limits its upward motion ; a loosely compressed rubber packing-ring embraces the spindle I.
Patent GB-189809319-A (GB)
Title: Improvements in Apparatus for the Production of Acetylene Gas.
Inventor: JAVAL ALFRED
Filed: 1898-04-22
Granted: 1899-03-25
Abstract: 9319. Javal, A. April 22. Acetylene.-The generator consists of a cylindrical vat A, open at the top and slightly conical at the bottom a. An inner wall A<1> is secured to the upper part of the vat so as to form a narrow annular water space, into which one part B of the inverted bell cover C dips. The lower part of the wall B is provided with rollers or projections d, and the lower part c of the cover C, which is open at the too, has a central dome D. Water is admitted through a tap E and funnel e to the annular water space, and overflows to the chamber A. The carbide is contained in an annular series of inverted buckets H, carried by and removably secured to an annular distributing-table m. This table is supported by rollers x upon a bracket secured to the sides of the chamber A, and is guided by rollers y. Each bucket, as it arrives at a particular point, is discharged automatically by a catch s, holding the lid in place, being knocked on one side by a lever t projecting into its course. The table is moved forwards one step, each time the production of gas falls off sufficiently to cause the bell to drop. This is accomplished by a counterweight g, attached to a chain h passing over rollers i and joined to a cross-bar carried on supports from the side walls of the holder. This counterweight operates levers a', b<1>, and thereby forces one step forwards one of a set of pins c<1> on the underside of the table, the said pins corresponding in number to the number of buckets carried. The carbide then falls into a hopper K, from which it falls into a chamber M, and from the latter into the conduit V. The chambers K and M are each provided with a valve L or L<1>, and these are so connected together that as one opens the other closes. The carbide falls from the conduit V upon a grating of galvanized iron wire o, having a terminal turned-up edge s<1>. The gas generated passes to the outlet tube G through a perforated guard or cage t<1>, having a solid top, and filled with some purifying-substance. The delivery pipe G<1> is provided with two valves, one l for the service pipes, and the other l<1> to clear the apparatus of air or condensed water. The lime residue is washed down, and is mostly carried by the water up the tube P, from which it overflows through the outer tube P' as milk of lime. Occasionally, the lower discharging-valve Q may be opened, but this is usually not necessary.

The top 9<a> and bottom 9 of the cartridge may be formed of wire twisted to form a flat coil, or of perforated metal. Metal prongs may project from the sides into' the mass of carbide, so that, when the coils expand, owing to the swelling of the carbide when acted upon by water, they may assist to break up the central part of the charge.
Patent GB-189825211-A (GB)
Title: Improvements in or relating to Apparatus for Working Tubular Sections of Glass in the Production of Vials, and other Bottles, Syringes, and the like.
Inventor: CONDE JAMES BACHE
Filed: 1898-11-29
Granted: 1899-01-21
Abstract: 25,211. Conde, J. B. Nov. 29. Re-heating ; drawing; moulding.-Relates to a machine for forming glass vials, bottles, &c., or syringes or ear-droppers, from tubes previously necked, lipped, &c. at each end. The tubes A are fed down an inclined. track, and are received by recesses in the discs a, which transfer them one at a time to the position shown in Fig. 1, where they rest upon pairs of parallel rollers 18. The cam surfaces 14 on the discs 10 carried by the shaft 2 cause the reciprocating rods 11 with their heads 15 to move inwards so as to centre the tube A accurately. The cam surfaces 28 now allow the shaft 25, which is supported in bearing-blocks 25<a> sliding on guides 26, to descend, so as to bring the oppositely-bevelled rubber discs 29 in contact with the glass tube, which is thereby set in rotation. The tube is heated in the centre by means of a pair of blowpipe burners, the action of which is controlled by the cam 43, and the heads 15 being retracted, the outward pressure of the bevelled discs 29 draws the two ends of the tube outwards. so as to divide it at the centre, each section closing at the end exposed to the flame. The heads are then moved forwards, so as to bring the opposing bottoms thus formed adjacent to but not in contact with each other. They are again retracted, and a bottoming-plate 45 caused to pass between the two parts, so as to mould the bottoms when the heads again advance to press the sections against the plate. The feed-discs a finally discharge the two vials so produced on to an inclined track, and another tube is brought into position between the heads. The machine may be adapted to form syringes or ear-droppers with tapering nozzles, the tube being drawn out sufficiently to form the contracted portion, which is subsequently cut.
