Abstract: 682,299. Washing milk separator dishes. LUERS, E. June 27, 1951, No. 15230/51. Class 138 (i). In an apparatus for washing milk separator dishes wherein dirty dishes are arranged in a first stack for washing internally and removed manually one by one to a second stack for washing externally, the washings are performed by separate pairs of motor driven brushes disposed at the ends of two arms of a tiltable support. Tiltable, by means of a handle 12, at the top of a vertical frame leg 1, Fig. 1, is a V-shaped support having two arms 3. An electric motor 10 mounted on the support drives through belts and pulleys 6, tubular shafts 5 mounted in the arm ends. Each shaft 5 carries a pair of brushes. The brush pairs 8, 9, are adjustable.laterally by devices 7. Water is supplied to the brushes from a hose union 13 connecting with each arm 3 through control valves 14, and each arm is connected by a pipe 16 with its shaft 5 and thus nozzles 20. A valve 14 is operated only when its corresponding arm 3 is moved to a level position, by coacting with a cam member on the frame leg. In the two short frame legs 1 are arranged screwed spindles 21. One spindle supports a basket 25 receiving an upright stack of dirty dishes while the other spindle supports a basket 26 to receive one by one in inverted position dishes removed from the basket 25. Mechanical raising of the spindle of basket 25 and lowering of the spindle of basket 26, so the top of each stack of dishes is always in the correct position to be engaged by the brush pairs is effected as shown in Figs. 3 and 4. As the V- shaped support is tilted one way or the other it causes, through a bevel gear drive, the partial rotation one way or the other of a shaft 32. Movement of the shaft 32 is imparted to rods 35, 36 in two horizontal frame members 1. When the rod 35, Fig. 4, is moved to the right, by upwardly moving the brushes 8, a member 38 slidable in a slot 39 of a lever 40 rotates the lever relative to the spindle 21. A ratchet 41 on the lever 40 drives' a ratchet wheel 28 formed on a spindle nut 27 so that the spindle is raised. Rotation of the spindle is prevented by a rod 24 engaging in a slot 22, Fig. 3, the rod being removable from the slot by a handle 23 for the purposes of initially positioning the spindle. As well as causing the spindle to rise, the member 38 causes, through links 52, a spindle 50 to turn and thus turn a dish lifter 51, Fig. 5. When the rod 35 moves to the left in Fig. 4 the ratchet 41 slides over the wheel 28 which is positively held by another ratchet 29 so that the spindle remains stationary. Also the lifter 51 then slides freely over the upper edge of the stack. The lowering of the spindle of the basket 26 by raising the brushes 9 is effected in a similar manner by the movement of the rod 36 in one direction while it remains stationary during movement of the rod in the opposite direction. The dish lifting gear 50, 51, 52, is adjustable in position horizontally, to suit different sizes of dishes, by means of a slide member 43 clampable by a handle 46 on one horizontal frame member. To prevent the stack of upright dishes from buckling laterally when the lifter 51 is operated a dish holder 53, adjustable by a handle 55, is provided.
