Granted: 1904-05-13
Abstract: 10,857. Cole, C. G. May 13. Acetylene gas lamps.-In the construction shown in Fig. 1, the calcium carbide case D, made in hinged sections, is placed within a chamber B, which communicates through a pipe F with a gas bell or receiver T. When the gas bell is in its lowest position, it opens, by means of an internal or external rod U, a cock P, so that, if the hand cock Q is open, water can pass from the container C to the space between the double cap E of the carbide chamber B. Thence it trickles down tubes G and wires H to the carbide, and the gas generated lifts the bell T and gradually closes the water cock P. The gas is conveyed from the bell T to the burner by a pipe I. The bell T and the rod U may be dispensed with, the gas being then consumed as generated. Fig. 5 shows a generator which may be attached by a clip F<1> to a cycle frame 8. In this construction, the water supplied by the tubes G and the wires H is controlled through gearing M, L by a lever or pointer O. The hiuged sections of the carbide case D are secured by a cap X, Y, Figs. 1 and 5, and the chamber B is made gas-tight, in the one case, by an arrangement of hinged levers 6 and packing, and, in the other case, by a plug 4 having bevelled edges engaging expansible packing. A carbide case D, made in hinged sections, may be applied to lamps or other constructions, and the generators may be substituted for the candle tubes in existing carriage and like lamps.

Abstract: 17,099. Wicherski, W., and Robinski, M. Aug. 6. Moulding tiles.-Relates to extrusion machines for moulding three, four, or more roofing or other tiles simultaneously in the form of a hollow column, and to die-plates with movable slides or wires for producing ribs or projections. Fig. 3 shows a die-plate 1 fitted with slides 4 connected by links 9 to a plate 7, which is arranged to slide on a fixed bolt 10, and is held up against a spring 8 by catches 15 pivoted in the forked end of the bolt. The catches are turned up automatically into a vertical position to release the plate 7, and thus withdraw the slides to permit the formation of the ribs, by means of a tapered sleeve 17, which is attached to a rod 18 passing through the centre of the balanced table, and is actuated by a sleeve of the table coming in contact with an adjustable nut on the screwed end of the rod. Pins 5 limit the motion of the slides, and a spring 14 forces the catches apart into a locking position when the plate 7 is raised by the upward movement of the balanced table acting on the sleeve. In a modification, shown in Fig. 7, the slides 4, for stopping the flow of clay through the recesses 2 in the dieplate during the formation of the plain portions of the tiles, are retracted by U -shaped springs 22 when a conical head 26, 27 is depressed by the action of the table on the rod 18. To ensure a rapid movement of the slides to produce ribs with ends at right-angles to the tiles, a portion 27 of the head is arranged to slide on the rod 18, and is held by side springs 24 until the pressure of a spring 29 on the rod becomes too great. In the arrangement shown in Fig. 12, the slides 4 are attached to levers 31, 32, pivoted at 34, and operated by springs 33 and a cam-plate 39. A locking-bar 43, fixed to the lever 31, is formed with a projection, which hooks over the lever 32 when the cam is moved by a lever 40 to bring the slides over the rib-forming grooves 2 in the dieplate. The locking-bar is moved automatically, to release the levers, by the table striking a projection of a rod attached to a spring plate over the bar. In all these arrangements, the slides may be replaced by cutting-wires.
