Patent GB-189701370-A (GB)
Title: An Improvement relating to Incandescent Gas Lighting.
Inventor: BARTLETT FREDERICK GEORGE
Filed: 1897-01-19
Granted: 1897-12-04
Abstract: 1370. Bartlett, F. G. Jan. 19. Lighting gas.-Comprises improvements connected with the pilot lights of a series of burners controlled from one bye-pass main gas cock, as described in Specification No. 23,454, A.D. 1896. When the main gas supply is turned off and the burner valve a is closed, a ball or other valve e in the pilot pipe or passage f rests in its lowest position upon a seat s, which is grooved or serrated to permit gas to pass to the pilot flame. Upon turning on the gas, the pressure opens the burner valve a and maintains the pilot valve e in contact with its upper seating s<1>, which, being gas-tight, extinguishes the pilot flame after the burner has been lit. The turning off of the gas causes the pilot valve e to fall, and the pilot flame is re-lit from the burner before the latter is extinguished. A sleeve, having grooves communicating at their lower ends with the atmosphere, is arranged in the pilot tube to prevent back pressure on the valve a when the main gas supply is turned off.

Title: Improvements in Electric Arc-lamps.
Inventor: DELAVAU HIPPOLYTE
Filed: 1897-02-23
Granted: 1897-05-01
Abstract: 4934. Delavau, H., and BrÚrat, F. F. Feb. 23. Arc lamps are constructed with flat supply chambers D, each holding a row of carbons, and with clutch mechanisms for feeding these automatically. Each carbon is pointed at one end and recessed at the other, to fit the corresponding parts of those preceding and following it to the arc. The carbons in the chambers D are moved towards their outer sides by pressers F actuated by springs f<1>. The outer carbons are drawn downward by intermittently-acting clutches J. Each clutch consists of two jaws, on inclined rods K, which are held up by surrounding springs ; the jaws are linked to an adjusting-nut on a hollow movable core H', in a solenoid H, through which the carbon passes. The lamp being in circuit, current passes directly from one terminal a' to the other a<1> through a spring- held armature S<2>, a contact U, and a high-resistance electromagnet S. When the difference of potential is sufficient to cause the magnet S to lift the armature, contact is made at T. Current then passes by the armature S<2> and contact T through the two solenoids H. Each solenoid then draws down its core H<1>, closing the jaws J on the carbon, and drawing it down, until the breaking of contact at T allows the jaws to open again. The main current passes to the carbons by the chambers D, which are insulated, and through solenoids G. Each solenoid G operates a movable core G<1> and jaws similar to those at J, acting on the carbon to strike the arc on starting and keep it of proper length. An ash receptacle B is provided. A marble and asbestos stup fixed below the carbon points supports them when the lamp is not in operation.
