Bottling; filling jars, cans, and like receptacles. -Relates to machines for filling bottles, jars, cans, &c., with liquid or semi-liquid substances, and of the kind in which the supply is operated or controlled electrically. In an automatic machine in which the valve is operated in one direction electrically, and in the other direction by gravity or spring action, and in which a part of the valve spindle a<1>, Fig. 2, forms the core of a. solenoid c, the spindle and the core are guided vertically by the downwardly-extending arms d<1> of a plate d on the spindle a' engaging in openings in a support f. As the spindle moves upwards, a finger d<2> on the plate d operates a lever h, thereby separating contact-pieces k, k<1> and bringing a lamp m into the circuit as described in Specification 1538/06. In a semi-automatic machine in which the lever n, Figs. 6 and 7, that operates the valve is manually moved in one direction and released by electrical means to allow the valve to close, the catch-piece p that engages the lever n is connected to the core a<2> of the solenoid c by a pin-and-slot connexion p<1>, a<5> to allow the core to commence its movement without load. The valve is opened by depressing a foot-lever o which is connected by a link o<2> to a slide o<1> that carries an upright o<3> connected to the lever n. When a current of high tension is employed, an additional circuit q, Fig. 9, containing a high-resistance coil q<1>, is arranged between the terminal t and an electro-magnet s<3>. The end b<1> of the beam of the scale pan rises when a receptacle is charged and completes a circuit through the framework s, bearings s<1>, contact-pieces s<2>, and electro-magnet s<3>, and through the parts shown in Fig. 7. In an automatic machine in which the current passing through the solenoid is not strong enough to raise the valve but sufficient to retain it in the open position, the valve is raised manually, the upright o<3>, Fig. 6, being connected to a plate which is mounted on the valve spindle and has a part forming the core of the solenoid.
