Abstract: 630,629. Washing drinking glasses. PARRY, H. J., and CHESTER, H. G. May 1, 1947, No. 11665. [Class 138(i)] [Also in Group XXX] A vertical endless belt which is mounted on a deck, is provided with spacers between pairs of which drinking utensils are accommodated, guide rails parallel with the belt and outside the spacers keeping the utensils in place between the spacers while the utensils are moved towards a drying position over perforations in the deck through which washing liquid is impinged upon them, the liquid draining away through the perforations. As shown in Figs. 1, 2 and 3, a vertically mounted endless belt conveyer 34 and three disc conveyers 18, 19, 20, are mounted on a deck 12 of a cabinet 10. Guide rails 38- 42, 44-54, are mounted on, over and around the discs and around the discs and around the belt so that utensils to be washed such as drinking glasses are guided over perforations 36, 36a in the path of the belt where they are sprayed with germicidal washing fluid, drained and transferred to each disc in turn being first dried by hot air on discs 18, 19 and by cool or cooled air on disc 20. They are then  ejected on to an unloading part of the deck 12. The deck 12 has three circular apertures 15, 16, 17 in which the perforated discs 18, 19, 20 are mounted. The discs are belt-driven by an electric motor 28 through a reduction gear 27, disc 19 rotating anti-clockwise and discs 18, 20 clockwise. The conveyer belt 34 is mounted above the deck 12 on two flanged drums 32, 33, the shaft of drum 32 being belt driven from the electric motor 28. The belt 34 has a number of equi-distant spacers 35 attached to it, by which the drinking glasses are guided over the perforations 36, 36a in a section 37 of the deck 12. The glasses are manually positioned between the spaces 35. A frame 13 is mounted above the deck 12 and supports three removable glass covers over the discs and conveyer belt. The washing water is electrically heated in an insulated tank 62 which is mounted inside the casing 10 and which has a float valve for water level control and a thermostat for temperature control. Germicidal fluid from a tank 60 is mixed with the water, the amount being controlled by a drip-feed needle valve operated by a spindle 59 which is attached to a spring loaded lever 58 operated by arms 56 attached to the drum 33. The mixture of water and germicidal fluid is forced by a pump 66 through apertures in a pipe 67 which is located underneath larger apertures in the deck 37 below the conveyer belt so that the glasses are sprayed during the first half of their movement by the belt both internally and externally, any jets of liquid which miss the glasses being returned to clean them externally by the glass cover 13a over the belt. During, the remaining half of their conveyer belt travel, the glasses drain through the perforations 36 into a drip tray 70 which is connected to a waste pipe 71. Discs 18, 19 are supplied with hot dry air by a duct 73 which is mounted underneath them and which is connected to a motor-driven fan 68. Disc 20 is similarly supplied with cool air. In modifications, a conveyer belt may be substituted for the discs or the number of discs may be reduced.
