Abstract: 357,405. Sottle-washing machines. POWLEY & SONS, Ltd., R. and POWLEY, M., St. Mark's Road, Sunderland. Oct. 31, 1930, No. 32818. [Class 138 (i).] In a bottle-washing machine of the chain-conveyer type and in which jetting liquids of different kinds and varying temperatures are used, one liquid is heated, as by a steam coil, to a high temperature for one jetting and this heat is caused to pass by conduction only from the heated container through division walls to unheated liquid for the other jetting sections. Improved chain guards and bottle-feeding means are described. The devices are shown applied to a machine as described in Specification 307,773, [Class 138 (i), Washing and cleaning buildings &c.], wherein internal jetting nozzles 6, Fig. 2, at every pause of the conveyer, are raised into operative position engaging flared tubes 5 holding the inverted bottles. A heattransmitting tank 32, Fig. 1, is divided into three concentrically arranged adjacent compartments 33, 34, 35. An alkaline solution is heated by means (not shown) in the main solution tank 22 and a portion of the solution is delivered by a pump 23 by pipe 23a to a controlling valve 26, Fig. 3, and thence by pipes 41, 41a to top and bottom jets of the central and hottest jetting section 9, 9a. The remainder of the solution passes by pipes 37, 37a to compartments 33, 35 of the heat-transmitting container in which it is cooled, the solution being then delivered from the compartment 35 by pipe 39 to the bottom jet sections 8, 10, and from the other chamber 33 to corresponding top jets of the two upper jetting sections 8a, 10a while the intermediate compartment 34 of cold water delivers to a pump 24 by a pipe 41 to a valve 30 which delivers by pipes 40, 40a to the top and bottom warm water jetting sections 7, 7a, 11, 11a at the feed delivery end of the machine. The final rinse is preferably of cold water from the mains by piping 46 to jetting sections 12, 12a. This water, after rinsing, collects in a tray 15, Fig. 2, and thence by filter tank 21 and by pump 24 to the water chamber 34 where it is warmed. As hot liquid passes through chambers 33, 35 and cold through 34, the temperature of the solution will be reduced and the water raised by conduction only. Thus only one heating control is required. The delivery side of the pump 23 for the alkali solution is connected by a pipe 23a to the shunt valve 26 of a rotary sleeve type whereby the whole of the supply is cut off from the bottom jets and diverted to the top ones before the conveyer begins to move so as to avoid waste. As regards the bottle-feeding device, Fig. 5, each bottle is pushed head foremost on to its supporting tube 3 on the conveyer by a separate push member 60 yieldingly engaging the punt of the bottle. Each push member 60 is preferably a rocker retained by a counterweight 60b and all such rockers are independently pivoted on a bar 61, Fig. 6, carried by a reciprocating slide 62 with neck sockets 63 for centering the bottles. The slide is periodically advanced with the bottles in timed relation with the conveyer so that the upper arms 60c of the rockers engage the punts of the bottles which move with the slide whereby the necks engage over the tubes 6. The bottles are lifted off their cradle 62 by the next movement of the conveyer. In the bottle-discharging means, Fig. 4, the bottles are deposited by the conveyer in a horizontal position on to a slide 65 forming a cradle for the bottles which is then moved to an outer position as at C, Fig. 4, and then tilted to position D and delivered standing to a platform 66. The slide moves on a bed 65a pivoted to the frame of the machine, sliding movement being effected by a pair of levers 48 actuated by a cam 49 and connected by rods 50 to the slide. The bed 65a is operated by levers 51 actuated by a cam 52 and coupled by rods 53 to an arm 54 on the pivot pin 67 on which the bed is fixed. Specification 266,615, [Class 46, Filtering &c.], is referred to.
