117,557. Roberts, T. Nov. 14, 1917. 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 a flexible delivery tube, compressed by a lever or clip to arrest the flow of the liquid, is used. The flexible pipe b, Figs. 1 and 3, extending through the valve chamber a and provided with a mouthpiece or nipple a', is controlled by a spring-pressed spindle e which can be moved away from the tube to allow liquid to pass. A screwed plug d, adjustable towards and from the tube b, is provided opposite the rounded end e1 of the spindle e; and detachable plugs a1, a2 are fitted at the ends of the cylinder a. As shown in Figs. 1 and 3, the lever g is operated by a bowl k1 carried by a vertical rod k2 which is actuated by a foot-lever k. In a modification, Fig. 4, an extension e3 of the spindle forms the core of a solenoid s, and, when a bottle is placed upon a scale pan beneath the valve chamber a, an electric circuit is completed as described in Specification 1538/06, causing the solenoid to withdraw the spindle against the action of its spring. Or the spindle may carry the armature of an electromagnet. Instead of the spindle e pinching the tube, the spring may force the spindle away from the tube and the tube be pinched by manual or electric means. The supply vessel c, Fig. 1, may be supported by an upright e1 and ring c2, or the tube b may lead to a vessel at some distance and be fitted with a valve o, Fig. 4; in the latter case, a rigid tube or trough n, extending from the chamber a acts as a guide for the tube b. The valve o is made of glass, earthenware, or other substance not acted upon by the liquid.
