Title: Improvements in or relating to the manufacture of electric incandescent lamps
IPC: H01K3/10
Filed: 1936-02-07
Abstract: 461,590. Making supports for electric incandescent lamp filaments. GENERAL ELECTRIC CO., Ltd. Feb. 7, 1936, No. 3801. Convention date, June 17, 1935. [Classes 83 (ii) and 83 (iv)] [Also in Group XI] Bending ; welding.-In a machine for the manufacture of filament-supporting frames for tubular electric incandescent lamps a spine wire 2, Fig. 1, is advanced intermittently from a reel 1 to apparatus A for producing wire loops from a wire disposed transversely to the spine wire and welding these loops to the spine wire, after which the spine wire passes beneath apparatus B for providing and sealing glass beads at the welds and, if desired, at intermediate positions, the wire being advanced finally to apparatus C for inserting carrier wires for the filament into the glass beads. The wire 2 may be advanced intermittently by bifurcated gripping members 3 mounted on a support which is slidable upon a guide 4, the support being provided with pins 5 adapted to engage a driving disc (not shown), whereby it is moved along against the pull of a weight 6.. After each advancing operation the jaws of the member 3 are opened and the sliding member is returned by the weight. The means for forming and welding the wire loops comprise a pair of pulleys 9, 10, Fig. 2, which draw the wire 11 from a reel 12 and feed it through a die 14 in a plate 13 from whence it passes over a stationary block 7 which forms an electrode co-operating with a movable welding-electrode 8. The wire loop that is drawn off is curved by a pivoted oscillating template 16 which surrounds the electrode 7 and is formed with a groove to enable welding to be effected. The requisite length of wire to form the loop is cut off by a cutter-plate 18 which slides on the plate 13 under the action of a two-armed lever 21 operated by a cam 25 coacting with an adjustable stop 23 on the lever. After the wire loop is severed the electrode 8 is lowered to weld the loop to the wire 2 which is disposed transversely to it, the template 16 being raised subsequently to allow the attached loop to be advanced towards the next position B where the glass bead is attached. The part of the wire carrying the bead is next advanced over the apparatus C, Fig. 1, which comprises : (1) a pair of vertically movable jaws which grip the end of a wire unwound from a reel ; (2) a cutter for severing a short length of the wire ; (3) means for bending the lower end of the severed wire into an eye. The jaws are lifted to press the upper end of the wire into the glass bead. The jaws are subsequently opened to allow the intermittent movement of the supporting wire to proceed.

Abstract: 1,101,451. Valves. CHEMETRON CORPORATION. 28 Jan., 1965 [4 Feb., 1964], No. 3862/65. Heading F2V. [Also in Division B8] A filling valve on a machine for filling receptacles is held in place by a clamp which exerts a camming action. In the embodiments described the valve is secured by a band 12b<SP>1</SP> (Fig. 21) formed with inclined surfaces 184, 191 which engage corresponding surfaces on the body 183 of the machine and on the valve body 182 to pull these together when the band is tightened by a toggle link. A screw adjustment may alter the degree of tightening. In the embodiment of Fig. 21, a valve 209 is unseated by a compression spring 213 when a valve 115b is raised so that a portion 114b closes a passage 111b from a reservoir and opens a passage 97b from a measuring piston (83) (Fig. 7, not shown). The measuring piston then forces liquid over a weir formed by the wall of a fitting 198, to the delivery opening. In an alternative form the valve 209 is integral with the valve 114b, and the weir may be formed in the cylinder in which the valve plunger moves (Fig. 17, not shown) or by internal passages in the valve plunger (Fig. 10, not shown). The plunger may permit air above the weir to escape to the reservoir when the filling valve is closed. A sleeve valve 17 (Fig. 2) may, in a further alternative, replace the poppet valve, and the measuring piston and weir may be omitted, the valve being opened when the sleeve 17 is pushed upwardly by a receptacle 19 engaging a resilient pad 39. An air vent 42 connects the interior of the receptacle to the reservoir. In this form the fastening 12 may engage a spring seat 27 sprung into a groove 26 on the inner fixed portion 13 of the sleeve valve.
