Title: Improvements in Devices for Preventing Railway Accidents.
Inventor: BIERMANN HERMANN
Filed: 1897-05-10
Granted: 1898-01-22
Abstract: 11,562. Biermann, H. May 10. Brakes, automatic. A dynamo d, Fig. 1, on the engine is connected through the leads x to rollers e, f, which run on the ordinary rails a, b, the wheel of the vehicles being insulated to prevent shortcircuiting. In a shunt circuit y on the engine are inserted a bell, a brake or reversing device, and a resistance y, the resistance under normal conditions being so much greater than that of the track circuit that the alarm or stopping mechanism is not operated. Between the rails a, b are fixed a series of conducting-rails k<2>, which are divided into sections by insulators m, and are connected, through the rollers k, k<1>, with the branch circuit z<1>, z<2> on the engine. The rails a, b are normally connected through the duplicated electromagnetic circuit makers and breakers g, g', of which there are a pair for each section of the rails k<2>, but when a train enters one of these sections the circuit z, z' is completed through the electromagnets g, g<1> and breaks the main circuit between the rails a, b. The main circuit then passes through the contactmakers of the next section. When, owing to a broken rail, fishplate, &c., or two trains entering adjacent sections, whether in the same or opposite directions, the resistance in the main circuit is increased, the alarm or stopping mechanism in the shunt circuit y is operated.

Patent GB-189801539-A (GB)
Title: An Improvement in Apparatus for Extinguishing Lights after a Predetermined Time.
Inventor: GUNNING JOHN
Filed: 1898-01-19
Granted: 1898-11-19
Abstract: 1539. Gunning, J. Jan. 19. Extinguishing gas after a predetermined time. Apparatus of the type described in Specification No. 7011, A.D. 1897, is modified to permit of some of the lights being extinguished before the others, or of some or all of a number of gas lights being lowered sometime before their extinction. To extinguish some of the gas lights before the others, the gas cock L has a longitudinal channel l communicating with two transverse channels l<1>, l<2>, of which l<2> is the wider. Arms J, I are fixed at predetermined intervals on the disc G of the clockwork mechanism, which is wound up by pulling the chain C, a shoulder H on the disc G engaging with a projection M and turning the cock so that the channels l<1>, l<2> respectively register with the gas-supply pipes P, Q. The clockwork then rotates the disc G until the shorter arm J strikes the projection M, and turns the cock sufficiently to close the channel l<1> and extinguish the lights supplied by the pipe P. Subsequently the longer arm I strikes the projection N, and, turning the cock further, extinguishes the lights supplied by l<2> and Q. When it is required to first lower and subsequently extinguish the gas lights, a screw S is arranged to allow gas to pass from l<2> to P after the supply to P by the channel l<1> has been cut off. The extinction is afterwards effected by the arm I turning the cock and closing the channel l<2>.

Title: Improvements in or relating to Electrolytic Electrical Meters.
Inventor: BASTIAN CHARLES ORME
Filed: 1898-03-01
Granted: 1899-01-14
Abstract: 5034. Bastian, C. O. March 1. Quantity meters.-An electrolytic meter consists of a glass tube b containing acidulated water and two platinum electrodes h by which the current to be measured, or a known fraction of it, is passed through the liquid. The tube is fixed in a case a near an aluminium or other scale f, graduated by repeatedly adding a definite volume of liquid, the decomposition of which requires a convenient quantity of current. The scale is adjustable vertically and clamped by a nut e*, for setting the zero mark to the top of the liquid when the tube is refilled. The liquid may be covered with paraffin oil to prevent evaporation, and the tube is closed at the top by a plug, a curved outlet being provided through this, or through the side of the tube near the top. The Provisional Specification mentions covering outlets in the case with wire gauze to prevent ignition of the gases evolved in it. The electrodes are thin platinum sheets secured by glass beads on the sides of a rectangular glass frame g, so as to be near together. The glass frame is made with a vertical centre rod and foot g*. In the arrangement shown in Fig. 1, the electrodes are connected with platinum wires sealed in the tube b, the seals being protected by guttapercha or the like j applied outside. In a modified form, Fig. 6, the glass frame g is attached to a tube g<4> in which the connecting-wires are sealed and insulated. The wires may otherwise pass through two tubes on the glass frame, or may be held apart in the liquid but insulated. Two or more tubes may be connected in such a meter.

Granted: 1899-02-04
Abstract: 5177. Sayers, W. B., and Mavor & Coulson. March 2. Sparking, preventing.-Comprises improvements on the invention described in Specification No. 27,209, A.D. 1896, according to which reversing- poles are employed, in conjunction with commutator coils, for the purpose of enabling a fixed position of the brushes to be maintained without sparking. In one arrangement, Fig. 1, the reversing pole-pieces 1 and 1" are supported in close proximity to the field-magnet poles by a non- magnetic carrier 3, in such a manner that they can be adjusted relatively to the.armature and the field-magnet poles. The means for effecting this adjustment consist (1) of a pin-and-slot connection with the carrier 3, and (2) of set-screws 6 acting on the said carrier. According to another arrangement, Fig. 2, the reversing pole-pieces 1 and 1<a> are secured to the field-magnet poles 2 or to extensions thereof by means of screws 8, and are provided with distance-pieces b at one end and adjusting- screws 9 at the other. In some cases, the air gap between the armature surface and the field-magnet face i-3 made to gradually increase in radial width towards the polar edge, which is strengthened by ar nature reaction, and the reversing pole-piece is arranged comparatively close to the armature. The reversing pole-piece may be made up of iron laminae secured between side and end plates, and it may be attached to the field-magnet pole in a manner similar to that shown in Fig. 2, but with one end bearing directly against the said pole.

Granted: 1899-08-19
Abstract: 20,379. Wyke, T. H. Sept. 27. Water-pressure engines.-A water motor for operating the bellows of an organ or for other purposes comprises a double-acting cylinder C enclosed in a supporting-column B, and a pistonslide valve K regulating the admission and exhaust. The cylinder C is screwed to an internal collar B<1> in the column B, and has ports D, D near its ends communicating through the column with ports L', L<3> in the valve-chest. The piston E has flanges E<1> which overlap the ports D at the end of the stroke, so as to cause cushioning, the water trapped in the end of the cylinders having to pass through small ducts E<2> in the flanges. The slide valve K, as shown in longitudinal section in Fig. 2, has end pistons K<2> by which it is actuated, a cushioning action being produced by projections K<3> on the end covers. The end spaces are connected by passages N with a cock P, as shown in sectional plan in Fig. 3. This cock is turned backwards and forwards by the engine, a fork O<2> on the crosshead O<3> engaging a twisted rod O attached to the spindle P' of the cock P. The cock is thus made to connect the ends of the valve chamber alternately to the exhaust. Small passages K<4> through the pistons K' allow the pressure water to pass through and drive the valve towards the end which is connected to the exhaust. The waste pipe T is provided with a plug valve T', which can be raised or lowered to regulate the engine, by means of a lever T' attached to the usual indicator cord on the organ. A screw plug R is provided for regulating the exit aperture of the cock P.
