Title: Improvements in Mechanism for Electric Traction Systems in which the Electric Current is Supplied to the Cars or Locomotives from Studs, Sections of Rails or the like Laid in the Road.
Inventor: THOMPSON SILVANUS PHILLIPS
Filed: 1897-06-11
Granted: 1898-05-28
Abstract: 14,252. Thompson, S. P., and Walker, M. June 11. Electric railways and tramways on a road contact or sectional conductor system with electromagnetic switches similar to those described in Specifications Nos. 19,455, 19,455A, and 19,456, A.D. 1896. Conductors; switches; collectors.-In Specification No. 19,455A, A.D. 1896, the action of the switch depends on the closing or partial closing of a magnetic circuit by a mass of iron on the car. The initial or partial closing of the switch is now made independent of this iron mass, which only serves to complete the closing and to hold up the switch. The magnetic parts of one form of switch for this purpose are shown in Fig. 1, where the plunger P is moved up to the loose part Q by the solenoid, and then these parts are lifted when the iron skate K comes over them. This partial movement starts the switch, and may also break an earth connection of the stud S. Several methods of connecting the operating-coils with the mains F and switch contacts are also described. In Fig. 2 there are main studs S and auxiliary studs Z, and the skate collector is divided into five parts, connected K<2> to K<4> and K<3> to K<1> to the motor H. Current from one main stud S at the switch 1 passes to the forward auxiliary stud Z at the switch 2, and thence through the switch-operating coil M to the forward main stud S, and so to the motor. For running in the opposite direction to the arrow, the connections of the parts of the skates are reversed. Modifications of the skates &c. are described. By the use of two auxiliary studs Z with the switch coil between them, the main stud S is connected directly through the switch contacts to the feeder.

Title: Improvements in Machines for Moulding Bricks, Tiles, and the like.
Inventor: BLACK DAVID
Filed: 1897-11-01
Granted: 1898-01-22
Abstract: 25,279. Black, D. Nov. 1. Moulding bricks. -The wheel C, which revolves uniformly on a fixed shaft and in a fixed casing, has formed in it radial moulds D. Each mould, as it comes opposite the hopper X, Fig. 1, is charged and the clay levelled down by a 'doctor' M operated by projections N' on the wheel. A palette or cover is next dropped in and held in position as the wheel rotates, by contact with the inner surface of the casing, pressure being produced by a plunger I, operated by a cam K. On each mould reaching the lowest point in its revolution, the cam Q on the sleeve N, driven by separate gearing, gives the plunger I a further motion to eject the brick and its palette, which are received on arms S<1> (actuated by a cam on the sleeve N or by the projections N<1>) and deposited on a travelling band. The sides of the mould may be perforated to allow the escape of surplus clay, and the perforations are closed more or less, at the proper time, by a perforated plate actuated by cam surfaces on the casing. In a modification, Fig. 4, the plungers I are for ejection only, the compression being done by plungers W carried in slides outside the wheel and operated by cam surfaces on the casing, the slides being withdrawn transversely at the proper time by levers not shown ; or the plungers, before the ejection of the brick, may be detached from the wheel into the outside casing, round which they are carried by means of projections on the wheel. In another modification, pressure is exerted both on the top and sides of the brick by means of plungers operated by inclined surfaces on the casing. A hollow plunger with a separatelymoved bottom may be used in the hopper for filling the moulds.

Patent GB-189906946-A (GB)
Title: Improvements in or relating to Means for Actuating the Distributing Devices of Motors with Variable Admission, and for other purposes.
Inventor: BOULT ALFRED JULIUS
Filed: 1899-03-30
Granted: 1900-04-30
Abstract: 6946. Boult, A. J., [Aubrat, E.]. March 30. Valve gear.-Relates to means for actuating the distributing-devices of motors with variable admission, and for other purposes, in which oscillatory valves are worked under the control of a regulator in such a way as not to exert any disturbing reaction thereon. Figs. 1 and 3 show in end and side elevation respectively, and Fig. 2 shows in sectional plan, a form of the gear in which the opening of the valve, as well as the closing, is caused to take place under the influence of a spring. The valve is worked by an arm 3 fast on the valve shaft a, which arm is acted on by the closing-spring 11. Two other arms 1 and 2 are pivoted so as to swing freely concentrically to the axis of the spindle a, one of them 2 being acted on by the opening-spring 10, which is powerful enough to overcome the closing-spring 11. The other arm 1 is compulsorily rocked by an eccentric acting through the rod 8. The arm 2 carries a sliding latch 22, which can be slid transversely so as to engage either with the arm 1 or the arm 3. The spring 10 is compressed while the arm 2 engages with the arm 1, the latch is then disengaged from the arm 1 and engaged with the arm 3, and the spring 10 thereupon opens the valve, at the same time compressing the spring 11. At a certain moment the latch is caused to disengage the arm 3, and the valve is closed by the spring 11. The moment of disengagement depends upon the position, determined by the regulator, of a revolving cam 29, against which bears a spring-pressed bar 26 by which the latch 22 is operated. This bar and the latch are returned by a bent lever 35 coming against a stop, or by equivalent means. A modification is described without a spring and arm for opening the valve.

Patent GB-190014277-A (GB)
Title: Improvements in Circular Knitting Machines.
Inventor: JOHNSON JAMES YATE
Filed: 1900-08-09
Granted: 1901-11-09
Abstract: 14,277. Johnson, J. Y., [Scott, R. W., and Williams, L. N. D.]. Aug. 9. Circular knitting - machines.-Relates to means for throwing the instep needles into or out of action, for operating the fashioning-pickers, and for putting on the work, and consists in improvements on the machines described in Specifications No. 11,421, A.D. 1894, and No. 14,157, A.D. 1899. The cam 3 for raising the long-butted instep needles out of action slides in guides in the cam ring 2, and has an inclined lower edge. A cam 5 pivoted on a rocking shaft 17 is moved, by intermediate mechanism controlled by lugs on a pattern disc, into the path of, and so raises, the cam 3. When the cam is raised, a spring trigger 6, Figs. 1, 3, and 5, descends to the position shown in Fig. 5 and holds the cam 3 elevated until the trigger is tripped by a fixed pin 7. The instep needle-depressing cam 4 is normally pressed outwards by a spring. When the needles are to be depressed, a disc 22, controlled by means of lugs on the pattern disc and intermediate mechanism, is raised, and strikes the lug 24 and moves the cam inwards into its operative position, in which it is held by the spring trigger 25. When the needles are all depressed, the disc 22 is raided a little more, and disengages the trigger 25, so freeing the cam and allowing it to spring out of action. The elevating and lowering pickers 32, 33 are carried on a ring 34 frictionally carried along by the cam ring 2. When the elevating - picker strikes a needle butt, relative motion takes place between the ring 34 and the ring 2, and a cam 36 causes the picker to rise against the action of a spring and then fall until it has disengaged the needle. The picker is brought back to its iuitial position by the picker carrier striking against a buffer or stop 42 or 43 ; this causes a relative motion between the rings 34 and 2, and so allows the cam 36 to depress the picker fully. The lowering picker is similarly operated. The stops are carried on slides 46 connected by a yoke 47, and are moved radially to put them into or out of action by means controlled from the pattern disc. The Provisional Specification describes means for facilitating the putting on of work. The instep needles are raised out of range of the knitting cams by the cam 3, and the knitting-cams are brought below them ; the other half of the needle is then raised by a ring having upwardly-projecting pins bearing on the bottoms of the needles.
