Title: Improvements in Relief Stamping and Printing Machines.
Filed: 1899-07-18
Granted: 1900-09-18
Abstract: 14,749. Waite, F., and Waite & Saville. July 18. Stamping. - Relates to relief stamping and printing machines, that is to say machines for printing in relief by means of an engraved or similar die or plate. Fig. 4 shows a vertical section of the machine. The die 6 is fixed on a holder 5 which is supported by a carriage 4 which is reciprocated in guides 3 by the rocking shaft 63 and toggle-levers 70, 71. The levers 70, 71 are so arranged that, when the carriage 4 reaches the printing end of .its stroke, they are about to pass the dead centre. This causes a dwell at the end of the stroke, which is prolonged by the carriage being brought against a fixed stop 39, and the further movement of the levers simply compresses the spring 28. The die holder 5 has a central projection 12 extending down through an opening in the carriage towards the top 13 of the plunger frame 14 by which the die 6 is raised and lowered. The frame 14 is raised to give the impression by the two eccentric rollers 8, 18, which are geared together by teeth a at their centre. The paper to be pressed is laid on a rising and falling feed-table 48 having an opening large enough for the die to pass through. The impression plate 30 to which the "force" is fixed face downwards is formed on or secured to the bottom of the vertical slide 31, the upper edge of which is inclined and is adjusted in position by means of the wedge 34. The wiper 79 is mounted in a frame 72 pivoted concentrically with the shaft 76 of the paper-feeding roller 77. The paper 75 is wound off the roll 74, around the wiper 79 and the feed-roller 77, on to the roll 84. The frame 72 is lifted to raise the wiper 79 and allow the carriage 4 to pass to the inking- roller by means of fingers 86 mounted upon a rocking shaft 88 and engaging with antifriction rollers 89 on the frame 72.

Title: Improvements in Controlling Alternating Electric Current Motors.
Filed: 1899-11-28
Granted: 1900-01-27
Abstract: 23,740. British Thomson-Houston Co., [Steinmetz, C. P.]. Nov. 28. Switches.-Relates to apparatus for controlling alternating-current induction motors in such a manner that the necessity for any special means for extinguishing arcs at the controller contacts is obviated. In stopping the motor, a non-inductive resistance is first connected with the windings of the secondary or induced member, and the windings are then open-circuited ; the resistance is next connected with the windings of the primary or inducing member, and finally the latter are opencircuited. Fig. 3 shows diagrammatically the primary windings a<1>, a<2>, a<3> and the secondary windings b<1>, b<2>, b<3> of the motor connected with a suitable form of controlling-switch. The primary and secondary windings are connected to two concentric series of contacts a<11>, a<22>, a<23> and b<11>, b<22>, b<33> respectively, outside which are arranged three series of resistance contacts R', R<2>, R<3>. Two sets of bridging-contacts m<1>, m<2>, m<3> and l<1>, l<2>, l<3> are employed for making connection between the resistance contacts and those of the primary and secondary motor windings respectively. When the motor is not running, the bridging-contacts rest upon insulated plates k<1>, k<2>, k<3>, situated between the three series of resistance contacts. The arms carrying the bridging-contacts are successively operated by the same switch handle, which is thrown into gear, first with one and then with the other, by means of a spring pawl actuated by a cam.

Patent GB-190003105-A (GB)
Title: Improvements in Systems of Electrical Distribution and Safety Apparatus therefor.
Inventor: REED LYMAN COLEMAN
Filed: 1900-02-16
Granted: 1900-03-31
Abstract: 3105. Reed, L. C., Reed, W. B., and Farrar, E. H. Feb. 16. Distributing; cut-outs; transformers.-Relates to means for protecting a house or like circuit in the event of the service wires being charged with a dangerous current. Figs. 1 and 2 show the construction of a cut-out device suitable for a threewire system, and Fig. 6 a diagram of connections. Within a casing 1 is fitted a three-pole switch comprising a lever 16 pivoted to a post 18 and carrying the three bridging-contacts 13, 14, 15. The other arm of the lever is slotted, and through the slot passes a pin 21 carried by the stem 22 of the branch core of a transformer-solenoid. The core is normally held up to close the switch by a fuse 27. This fuse is in the closed circuit of the secondary coil 29 of the transformer, the primary 31 of which connects the neutral wire 42 of the house system with earth through the conductors 35 and 36. Should an excessive direct current flow through the apparatus, the pull on the core is sufficient to break the fuse 27 and then lift the lever 16 to open the circuit. With an alternating current in the primary, a secondary current is produced in the secondary and the fuse is melted, the primary coil serving as a choking coil to diminish arcing. In Fig. 6 a connection is shown at 47 with a high-tension circuit, leakages occurring at 51 and 52. Under these circumstances or other similar ones the circuit-breaker operates. In twowire systems it is necessary that all the circuitbreakers should be connected to the same wire.

Patent GB-190008682-A (GB)
Title: Improvements in Apparatus for Measuring Electrical Resistances, and chiefly intended for Testing the Electrical Resistance of Rail Joints in the Tracks of Electric Railways.
Inventor: CONANT ROGER WINTHROP
Filed: 1900-05-10
Granted: 1900-06-16
Abstract: 8682. Conant, R. W. Nov. 13, A.D. 1899, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Testing.-Low resistances are compared by portable apparatus, shown diagrammatically in Fig. 5 as applied for balancing the resistance of a rail joint against that of a variable length of solid rail 50, through which current is passing, and with which connections are made by three metal points 43, 44, 45 on wooden handles. The two outer points 43, 45 are connected by wires 40, 42 of equal resistance to plates e, d, either or both of which may be connected by a switch f through a telephone s and a contact-breaker 9 with the middle point 44. The two resistances may be compared by the amounts of noise produced when the switch f is placed on each contact d, e successively ; if the resistances are equal, no noise is produced when the switch f touches both contacts d, e. The telephone may be connected through an induction coil, but is preferably connected directly, in parallel with an inductance coil 29 and a variable resistance 27 ; the coil 29 reduces the noise when circuit is made, increasing it when broken, and the resistance 27 serves as an adjustment for different currents. The contactbreaker 9 is a spring in contact with a toothed wheel rotated by a clock movement, and stopped or started by a pivoted arm m, serving also as a switch. Two such contact-breakers, either of which may be connected by its switch m, are supported on noise-damping packing in a box, which also contains the inductance coil 29, and carries the switch f, variable resistance 27, and terminals for the point and telephone connections ; the box is provided with a shoulder strap. The contact-breaker and switch f may be dispensed with, by making suitable contacts with the points 43, 44, 45.
Patent GB-190009537-A (GB)
Title: Improvements in Acetylene Gas Generators or the like
Inventor: ROSS JOHN HOWARD
Filed: 1900-05-24
Granted: 1901-05-04
Abstract: 9537. Ross, J. H. May 24. Gases, obtaining.-Relates to producing gases by dropping a granulated solid into a liquid, and consists of apparatus by which specific charges of the solid are automatically fed into liquid, and of an oil trap through which the solid passes into the liquid. The invention is described as applied to an acetylene lamp, the body of which is shown in Fig. 8. The carbide is placed in a container a, Fig. 2, communicating by a neck b and a spherical end c with the measuring- hopper d, carried by a ring g secured to a spindle f. The hopper is provided with a spout j, k, which is brought against a stop l when the gas holder ascends, and in this position the spout becomes charged. When the gas holder descends, the hopper is turned into the position shown in Fig. 3, and the spout k discharges its contents into the water. The hopper is actuated by the holder q through a rod t, pin w, plate u sliding in guides v, pin x, forked lever z, and spindle f. The hopper is locked in the position shown in Fig. 2 by a rib 8 in the plate u passing into the backwardly-bent end y of the fork z, as the pin x passes up out of the fork. Escape of gas about the spindle f is prevented by the construction shown in Fig. 7, in which a rubber tube 4 is fixed at one end to a sleeve 3 soldered to the spindle, and at the other end to a sleeve 2 which is soldered to the box e and to the bearing- sleeve 1. In the body of the lamp is an annular chamber r, containing the gas-holder bell q floating in water. The carbide drops from the spout k into a chamber e, and falls thence through the outlet m and hood 12 into the oil trap. This trap consists of two cylinders 25 and 26 charged with oil, and two cones 23 and 20. The cones deflect the falling carbide so that it reaches the bottom of the vessel outside the cylinders, and any gas which may enter the outer cylinder is prevented from entering the inner one and so gaining access to the pipe m. The gas passes from the generator into the bell q by the pipe p, and it is conducted to the burners by the pipe 10. In a modification, the oil trap is at the side of the generator, and is formed in part by the bottom of the chamber o being made to slope upwards. The Provisional Specification describes modifications of the carbide hopper and its spouts, and of the mechanism for operating them.

Abstract: 16,075. Hagey, R. J. Sept. 10. Exposures, determining.-Relates to a device constructed on the principle of the slide-rule for calculating the time of exposure of a photographic plate from the usual factors, namely, ratio of focal length to aperture, intensity of light, and sensitiveness of the plate. On the rear card is drawn a chart of curves 4, which determine the normal intensity of light at any given hour and date. The number. corresponding to the ratio of focal length to aperture on the upper edge of the sliding scale 2 is set to the point indicating the intensity light on the chart. Vertical lines drawn on the transparent cover 3 of the card indicate the deviations on each side of the normal light, which is marked by an arrow. The line selected marks the required time of exposure, in tenths of seconds, on the lower edge of the scale 2. Numbers denoting the sensitiveness of the plate are marked on a scale, and the transparent cover 3 is displaced laterally until the arrow points to the sensitiveness of the plate being used, this, of course, making a corresponding difference in the time of exposure read from the scale 2. A number of factors for different subjects are marked on the scale, to enable the necessary correction of the result read from the scale to be made.

Abstract: 4486. Hatt, E. J. March 2. Locks, key.-In connection with a safety lock, means are piovided for preventing the operation of the lock by a pick Jock or a wrong key. The locking-bolt'a a is provided with notches c, and on one side of the bolt is pivoted an arm d pressed into contact with the bolt by a spring f. A locking-bar h, pivoted at one end to the arm d, passes behind the bolt, and terminates in a beak i guided between a block k. A wedge-piece l, which is mounted in a support m and guided by a pin n passing through a slot, engages a bevelled portion of the bar h. The short bit p of the key is adapted to engage a curved part r of the wedge-piece l, and the long bit o engages a recess q in the bolt. Fig. 1 shows the bolt in the locking position. When it is desired to withdraw the bolt, the key is turned so that the short bit p raises the piece l, and consequently operates the bar h so as to bring both the beak i and a projection on the arm d clear of the notches c. The bolt can then be withdrawn by the action of the bit o. Should a key, having a bit p longer or shorter than the proper length, be inserted, then the beak i or the projection on the arm d engages the notch, and the bolt cannot be withdrawn.
