Abstract: 28,462. Mills, B. J. B., [Winckler, A, and Winckler, C.]. Dec. 27. Bottles, washing.-Consists of means for washing bottles by a jet of water containing india-rubber, ebonite, pumicestone, carbon, or other material which does not scratch glass, and rinsing by a jet of water alone without removing the bottles, which are afterwards removed automatically. Water passes from the pipe d, Fig. 1, through a short narrow tube a with a truncated, conical, end opecing into a circular chamber c, through a diverging nozzle b, and into a helical tube e, over which, and in a conical funnel g, a bottle is held. The water from the narrow tube a draws with it a mixture of water and ebonite or other pellicles from a vessel p through a tube i into the chamber c, and forces them over the interior of the bottle. The water, ebonite, and removed dirt flow out round the neck of the bottle and fall into the vessel p. The tube i is afterwards removed from the vessel and pure water only used for rinsing ; this is then cut off and the bottle removed. These operations are effected automatically in the apparatus shown in Fig. 3, wherein the tubes d and bottles are supported by arms n on a cap s carried so that it fits about a cylinder r into which water enters under pressure. An annular chamber t in the cap s, fitted with cup-leathers v, communicates by orifices u on one side with the chamber r, and on the other, by orifices o, with valves q commanding the pipes d. The valves q are opened and shut by an annular cam-surface y which, on the rotation of the cap s, operates the valve-stems. The distribution of solid particles to the jet may be similarly controlled, a rigid tube i being used. The bottles may be brought to and removed from the apparatus by mechanism shown in Fig. 5. In this mechanism, a fork 21 lifts the bottle to the position f<1> and allows it to slide on to a platform 4, where it rests against a face 5 and is carried along by an Archimedean screw 3 till it is removed or falls into a bucket of water. The screw is turned so that a bottle falls between each pair of contiguous turns of the screw blade. The fork 21 which lifts the bottles is pivoted at 18 on a frame 7 pivoted at 20. The frame 7 is formed with a cam-groove traversed by a pin 8 on a crank keyed on the main shaft 13. A connecting-rod 12 is pivoted on the pin 8, and is connected by a long slot to the lever 14 on the axis 18. As the pin 8 traverses the part 8-10 of the cam-groove which is concentric with the shaft 13, the frame 7 remains motionless, but the fork 21 lifts the bottle to the position f<1>; during the passage from the position 10 to the position 9, the frame moves to the position shown in dotted lines, and the fork 21 resumes a horizontal position behind the next bottle. The course from the position 9 to the position 11 is concentric with the shaft 13, while, during the remainder of the cycle, the fork resumes its original position. The bottles may be washed externally with hot water and afterwards rinsed with cold water sprinkled from horizontal perforated pipes over the conveyer. A rubber of metallic meshes or brushes may be used, operating automatically to remove the labels.
