Title: Improvements in electric lighting systems for the headlights of motor vehicles
IPC: H01H50/28
Filed: 1928-12-17
Abstract: 321,862. Ericsson, J. S. Dec. 17, 1928. Controlling consuming devices. - In lighting systems for motor headlamps, of the kind in which the light is dimmed by means of an alternative lamp or filament switched in by an electromagnetic relay controlled by a hand switch near the driver, one end of the coil 3, Figs. 1 and 5, of the relay is connected permanently to the moving contact 9 and through a switch 25 to the current source 21. When the coil 3 is energized, the contact 9 is pressed on to a fixed contact 8 and off a fixed contact 7 normally engaging it. Terminals 11 - - 14 of the relay are connected respectively to the contacts 7, 9, and 8 and to the other end of the coil 3. A main lamp 16 and a small lamp 17, or two filaments in one bulb, are connected to the terminals 11, 13. To dim the light, the main lamp or filament is switched off and the small one on, by energization of the coil 3 when a push-button 19 is depressed, or more permanently, by moving the switch 25 to the left. The relay may be easily incorporated in existing systems and may be mounted between the casing of the headlight and the reflector. The coil 3 is secured to the relay casing 1 by an iron screw 4 forming the core. A spring armature 5 carries an insulator 6 operating the contact 9.

[Also in Division B8] In apparatus for filling and sealing containers (see Division B8), the sealing is effected by a rotary device, Figs. 13 and 17, to which containers are fed by an endless conveyer 22 having carriers 12 each supporting a filled container. The conveyer engages a continuously rotating sprocket wheel 100, and during the passage of a container carrier from the position 0 degrees, Fig. 13, to a position 95 degrees, a disc-like cap 6 is sealed to the container top. Each container carrier 12 is associated with a cap applying head 130 and a cap magazine 102; the magazines are carried in the sprocket wheel and arranged in pairs, and each houses a pile of caps 6 urged upwards by a spring 122 and follower 120. Each pair is supported by a clamp 108 on an arm 114. The uppermost cap engages edges of overlying plates 126, Fig. 16, and is removed radially outwards by a suction head 130; the cap is moved upwardly and radially outwardly until it is positioned above a filled container in its carrier, and it then moves downwards to be sealed on to the container top. The head comprises an apertured disc 150 of rubber within a hollow body 154 connected to a suction line 160. The head, Figs. 15 and 17, is connected to a plunger vertically slidable in a sleeve 166 and urged downwardly by a spring 170 abutting a plug 174. The head and plunger assembly are mounted in a slide 140 engaging a guideway 141 in a member 141 in a member 132 rotating with the wheel, and as the wheel rotates a cam roller 176 of the plug 174 engages a cam track on a fixed member 148 to provide vertical movement of the head. A cam roller 142 on the slide is positioned in a cam slot in the fixed member 148 and provides the inner and outer radial movements of the head. Safety mechanisms are provided to prevent a head which has not picked up a cap from moving downwardly into sealing position. A valve 206 associated with each head controls the application of reduced pressure thereto, and all such valves are automatically operated by fixed cams surrounding the device. Specification 951,599 is referred to.
