Title: Improvements in Electric Arc Lamps.
Inventor: GORE FREDERICK WILLIAM
Filed: 1903-04-14
Granted: 1903-07-02
Abstract: 8512. Gore, F. W. April 14. Arc lamps.-The arc is struck by an electromagnetically-operated clutch, the movements of the upper and lower carbons being regulated by pneumatic dash-pots. The current passes through the resistance coil 13, Fig. 1, to the contact-piece 31<a> on the wire 31 and thence through the block 30<a> and wire 30 to the upper carbon-holder 34 and to the coils of the electromagnet 29, which draws down the pivoted clutch 27. The clutch 27 is connected to a rod 26 in the hollow frame 5, so that the cross-bar 24, pivoted to the extension 5a, is lowered, and the frame 18, which is supported on the cross-bar 24 by means of the stop 25, also falls carrying with it the carbon 19, and forming the arc. The falling of the frame 18 is checked by a piston 23, Fig. 2, attached to it and working in a cylinder 20, the descent of the piston closing the ball valve 21<a>. As the carbons consume, the current weakens until the spring 28, Fig. 1, which is connected to the upper end of the rod 26, lifts the clutch 27 and the cross-bar 24. The raising of the clutch 27 releases the upper carbon-holder 34, the descent of which is regulated by the piston 15<a> working in the cylinder 14 and closing the ball valve 14<a>. If the carbons break, the upper carbon falls until the contact-piece 41 strikes the spring lever 40<a>, which makes contact with the projection 35<a> on the negative lead 35, so that the carbons are short-circuited, the current passing through the low-resistance coil 38. The tension of the spring 28 may be adjusted by a pin in a notched slot 5<b> in the hollow frame 5.
