Abstract: 410,209. Bottle washing machines. PHILLIPS, P. B., and APPLETON, H., 277, High Street, Rochester, Kent. Nov. 17, 1932, No. 32560. [Class 138 (i).] In a machine for washing bottles and like articles, having a hydraulic ram for moving the bottles through the machine, the exhaust water from the ram is used as a cleansing medium or as a source for hydraulic means for driving movable cleansing nozzles: In the construction shown in Figs. 1, 3, and 5, the machine comprises a washing section 10 and a rinsing section 11, through which bottles on carriers 20 are pushed by means of a hydraulic ram 12. The plunger of the ram has a cross-bar 23 adapted to engage one end of a carrier 20 mounted on rails 19 and move the carrier to a position within the section 10 such that the inverted bottles are in register with nozzles of boxes 25, 26. The box 25 is vertically slidable and is connected by bell crank levers 42 and rods 41 to a bar 39 slidable in slots and engaged by the crossbar 23 on the return stroke of the ram plunger so that the nozzles 38 enter the bottles above the box 25. Liquid is sprayed through the boxes by means of a pump. The carrier 20 during its forward movement pushes an adjacent carrier to the rinsing section where the bottles are rinsed by liquid from nozzles is a movable box 45 and a stationary box 46. The box 45 is operated by bell crank levers 48 linked by connecting rods 49 to the bell crank levers 42. The bottles in both sections 10, 11 are cleansed externally by sprays located above and at the sides of the carriers. Rinsing liquid for the box 46 and for a spray pipe 50 is obtained from the exhaust water of the ram 12 through pipes 61, 60, respectively. The ram, as shown in Fig. 5, is controlled by a four-way cock 22 having a handle 52. Pressure is applied behind the ram from supply pipe 53 by way of pipe 54, exhaust taking place through pipe 55 and exhaust port 56. The return of the ram is effected by reversal of the cock 22 when pressure is applied by way of pipe 55 and exhaust takes place through pipe 54. The exhaust port 56 is connected to trip valves 57, 58 which control the supply of liquid to the box 46 and the spray pipe 50. The shaft of the handle 52 has a two-armed lever 59 arranged to open one or other of the valves 57, 58 depending upon the position of the control handle. The arrangement is such that upon the forward movement of the ram, exhaust liquid from the pipe 55 issues from the spray pipe 50, and upon reversal of the ram, exhaust liquid from the pipe 54 passes through the nozzles of the jet box 46. In a modification, a rotary sleeve valve controls the flow of liquid to the pipe 50 and box 46. Other means than that described may be used to raise the movable boxes 25, 45, for example, inclined planes on a reciprocating bar may operate on rollers on the boxes, rack and pinion gearing or wire ropes over pulleys may be employed, or the boxes may be lifted hydraulically, the exhaust water from the ram 12 being utilized. As shown in Fig. 7, the box 45 is connected through a bell crank lever 82 to the piston of a ram 80. The cylinder of the ram is provided with two ports, one communicating through a valve 83 with a pipe 84 leading to a tank 17, the other leading to a T-connection, one passage of which leads to the control valve 22 while the other passage leads through a spring-loaded valve 86 to the box 45. The valve 83 is operated, through a connecting rod 85, by the handle 52. In the position shown, the exhaust water from the ram 12 passes through pipe 61<a> to the ram 80 moving the piston to the left and thereby raising the box 45. Continued pressure of the exhaust water opens the valve 86 and discharges through the nozzles in the box 45.
