Abstract: 688,418. Bottle washing machines. SEITZWERKE GES. Oct. 2, 1950 [Sept. 30, 1949], No. 23990/50. Class 138 (i). [Also in Group XXX] A machine for washing bottles and the like has bottle baskets independent of each other and separately removable, and intermittently actuated conveying means for translating the baskets one by one from one working station to other successive working stations, and the baskets after being loaded are individually inverted and then held stationary in one or more positions for the internal flushing of the bottles and are afterwards returned to an upright position for passage through an immersion bath. The machine comprises a bath 31, through which baskets 12 for bottles 11 are moved along the lower portion of a rail 30 and subsequently delivered from the upper portion of the rail 30 to an intermittently driven notched guidewheel 13, a discharge track 14 from which bottles 11 are delivered to a conveyer 15, a loading track 16 from which the bottles are loaded into a basket, and a second intermittently driven notched guidewheel 23 which transfers a basket to positions over two sets of flushing jets 28, 29 arranged in a pipe 27 and then tilts the basket at E and finally delivers it to the lower portion of the rail 30. Each basket has an upper roller 19, a lower roller 17 and a closing hoop 33. As a basket is carried upwards by the wheel 13 by a notch thereon engaging the spindle of the roller 19, the roller 17 engages a fixed guide 34 which causes the basket to tilt at position D and the closing hoop 33 to open by gravity so that the bottles are delivered to the track 14. When the wheel 13 again moves co-operation between the rollers 17 and 19 with the guide 34 and an arcuate cam rail 21 causes the basket 12 to assume a horizontal position opposite the loading track 16, the roller 17 then engaging the end of a tongue 18. After bottles have been loaded the basket is moved to a substantially vertical position above the pipe 27 so that the bottles are jetted internally by the jets 28. This position is assumed by the roller 17 falling down the surface of the tongue 18 and its spindle contacting a slope 24 on the wheel 23 and finally entering one of a plurality of notches 22 thereon, while the roller 19 finally engages with the upper side of a horizontal rail 26 continuing from the tongue 18. The basket is secured for jetting by the roller 19 on the rail 26 and the spindle of roller 17 engaging one side of the notch 22. When the wheel 23 again rotates the basket is moved to a position so that the bottles are jetted from jets 29 also in the pipe 27. In this second jetting position the basket is secured by the spindles of the rollers 19, 17 engaging parts of the sides of the notch 22 while the roller 19 engages the cam rail 26. The basket is then moved to the position E the roller 19 passing round an arcuate extension of the track 26. In this position a pin 32 on the hoop 33 is engaged by a side of the notch 22 so that the hoop is moved to a basket closing position against gravity to prevent bottles sliding out of the basket. The basket is then moved to a vertical' hanging position within the soaking bath 31 the roller 17 then engaging an inner surface of the arcuate extension of the rail 26. Finally the basket is transferred on to the rail 30 extending from the arcuate extension. Instead of a common jetting tube 27 two separate tubes may be employed.
