Abstract: 561,430. Conveyers. TRIGGS, W. W. (American Can Co.). Sept. 16, 1942, No. 13080. [Class 78 (i)] [Also in Group II] In an apparatus for treating black plate blanks or sheets preparatory to uniting margins of each sheet or blank by soldering or welding, the blanks &c. are conveyed through deoxidising, washing, and drying chambers by one or more pairs of rotary screw conveyers, the side margins of each sheet &c. being sprayed with deoxidising liquid in the first chamber and then delivered to the washing chamber where the side margins are washed and then through the drying chamber where the sheets are dried by hot air projected along the side margins. The sheets A are fed from a table 17 and their edges received between the helical grooves of a pair of verticallydisposed screw conveyers 21 mounted on shafts 24, the lower ends of which are journalled in bearings 25 formed in the bottom of a casing 11 divided by walls 12 into a deoxidising chamber 13 in which the conveyers 21 are mounted, a washing chamber 14 and a drying chamber 15, the sheets being confined by rails 31. As the sheets A are carried down by the conveyers, pairs of sprayers 35 direct deoxidising liquid, e.g. acid, along the side margins of the sheets. Near the bottom of each conveyer the groove 22 changes to a greater pitch so that the sheet thereon may be separated from those above and is then engaged by fingers 43 formed on discs 42. The sheets are then moved by the fingers along rails 44, magnets 47 preventing their moving too fast, and come to rest against vertical guides 46 where their ends pass into the grooves 52 of a pair of vertical conveyers 51 similar to the conveyers 21. The sheets are raised upward by the conveyers 51 being sprayed with liquid as before by sprayers 35 and 61. When a sheet reaches the top of these conveyers it is separated by fingers 65 similar in shape to the fingers 43 and the sheet is passed along a pair of rails 68 depending from the cover-plate 16 of the casing 11 and into the grooves of a pair of screw conveyers 71 in the tank 14 where the side margins are sprayed with water by sprayers similar to the sprayers 35, 61. The sheets are lowered and raised by the conveyers 71 and 72 as before and the washed sheets are passed in similar fashion to the front pair of conveyers 125 in the drying chamber 15 where they are dried by hot air from sprayers similar to the sprayers 35, 61. The dried sheets are then removed for the second pair of conveyers 126 in similar fashion and are fed out to a table 165.

Patent GB-134061-A (GB)
IPC: B23B3/18
Abstract: 134,061. Potter, J. C. Nov. 12, 1918. Lathes.-In a multiple-spindle lathe the spindles are mounted in a table mounted on a slide which can be moved away from the tool-spindles. The table is rotated automatically to bring the spindles in succession into the working position, in which position they are rotated, the other spindles being stationary to allow the finished piece to be removed and a new piece put in place. The invention is shown as applied to a vertical lathe having a vertically moving tool-turret 119 and two horizontallymoving cross-slides 152. Two vertical workspindles carrying chucks 37 are mounted in an horizontal table 13 which is carried by an horizontally-sliding bed 67 which is moved outwards to carry the active spindle away from the tools before the table is rotated through half a revolution to bring the other spindle into the working position. The lathe is driven by a belt pulley on a shaft 14 which has a three-speed drive on to a shaft 24, which again has a three-speed drive on to a shaft 29, from which the various mechanisms are driven. The shaft 29, through bevelgear 30, 31, drives a half-clutch 34 which can be engaged with a half-clutch on the work-spindle 35 which is in alinement with it and in the working position. The clutch can be disengaged at any time by the treadle 44. When the clutch 34 is thrown out, a clutch 46, Fig. 2, is thrown in, and the cam-wheel 61 is rotated by the gear shown. While this wheel rotates, a path 63 holds the clutch 34 out of gear by means of a lever 66 mounted on the same rock-shaft as the clutch lever, until a bowl in the lever 66 is in line with a recess in the path 63, when a spring rocks the lever to throw in the clutch 34. As the cam rotates, it rocks a lever 75 by means of a camgroove 77 and puts into action the gear for withdrawing the bed 67. As the bed moves outwards, a dog rocks a lever 88 and puts into gear the table-rotating mechanism. Before the table can be rotated, a stop-pin is withdrawn from a recess 95, Fig. 1, in the table. When the table has completed a half-revolution, the pin is pressed by a spring into an opposite recess in the table. The turret and cross-slide actuating mechanisms are driven by vertical spindles, one of which is shown at 120. These mechanisms include reversing- gear comprising a clutch which is operated by a cam driven by a Geneva-stop mechanism. Specification 109,660 is referred to.
