Filed: 1955-01-03
Abstract: 763,678. Folding paper. MUELLER, E. Jan. 3, 1955, No. 133/55. Class 100(1) A web is folded zig-zag fashion by a rotary member from which blades entered for forming one fold in the web and which is provided with gripper device adjacent the axis of rotation for forming the other fold in the web. The folder comprises side frame members 20 from which extend vertical rods 21 and horizontal rods 22 the latter rods adjustably supporting a roller 27 over which a web W passes. Between the frame members 20 the rotary member including folding blades 11 is supported for movement anticlockwise as seen in Fig. 2 and comprises disc members one of which, 34, is connected to a shaft 35 which carries a suitably driven pulley 37. Adjacent the disc 34 is a stationary valve body 47 secured to the frame member 20 having a recess 49 communicating with a source of switch 51 and a recess 50 isolated from the sections and which may be such as to allow atmospheric air to leak therein. The recesses 49, 50 communicate through ports 46 to the disc 54 with suction casings 41 the upper surfaces 42 of which are provided with holes 45 for engaging the web. The casings 41 enter below the rotating discs such as 34 to which they are secured. The blades 11 comprise two sections the inner sections being secured to the casings 41 and the outer sections being adjustably secured by bolts 60 to the inner sections. Adjacent the suction casings 41 are mounted shafts 67 carrying power or' gripper members 66. The grippers 66 are operated by a resilient cam member 75 which, by engagement of rollers 71 mounted on arms 70 secured to the shafts 67, rotates the shafts 67. The shafts 67 are interconnected by a resilent link 77 so that on actuation by the cam 75 to cause the lower gripper 66 (Fig 2) to grip the web the 'upper gripper 66 is rotated in the opposite direction to its fully open position. In operation the blades 11 and 27 are first adjusted to correspond to the legth of fold required and a brush 80, for assisting in forming the crease C in the web is similarly adjusted on the rods 21. The web is then led over the blades 11 and folded under the left hand blade (Fig. 2) to be gripped by the lower gripper 66. As the blades rotate the web sections A and B are held by suction to the upper casing 41 whilst a crease C is made by the right hand blade 11 and brush 80. As the blades rotate further the upper gripper 66, which is now in the lower position, grips the web between the section A and B against the associated casing 41 the switch to that casing being then shut off, whilst suction is applied to the other casing for holding two more sections A, B of the web. As the blades rotate forth the gripper 66 is released, having made a fold F in the web which then drops on to a suitable receiver 85 aided by bails 64 mounted for swinging movement on the blades 11.

IPC: B65G47/00
Filed: 1953-01-05
Abstract: 729,175. Discharging endless-belt conveyers; feeding hoppers. RONCERAY, R. A. M. Jan. 5, 1953 [Nov. 28, 1952], No. 315/53. Class 78 (1). A bunker apparatus for foundry sand or similar material of the kind having a conveyer belt 5 supported on a frame 1 above a bunker 2 provided with a discharge gate 3, and two scrapers 7 for discharging material from the belt into the bunker at an automatically variable rate which is high when the bunker is empty but decreases as the bunker fills up, is characterised in that the bunker is suspended from the frame by resilient means 4 so that the bunker may rise and fall vertically as it is unloaded and loaded respectively and that the scrapers are mounted on vertical pivots 8 at opposite sides of the belt, the scrapers being connected to the bunker so that they are pivoted across the belt as the bunker rises and falls, thereby automatically varying the rate of discharge into the bunker according to the vertical position of the bunker. The resilient means 4 comprises two hollow cylinders, one attached to the bunker and the other to the frame 1 : alternatively, it may comprise a spiral spring. Each scraper is connected to the bunker by a cable 12 passing over a pulley 13, and to a counterweight 15 by a cable 16 passing over a pulley 17, the cable 12 extending from a tension device 14 to a scraper on the same side of the belt. and the cable 16 passing from the counterweight 15 through an opening 18 in the adjacent scraper to the scraper on the opposite side of the belt. As the bunker fills it sinks and through the cables 12 opens the sprapers so that a decreasing amount of sand is discharged from the belt, and when the bunker is full no sand is removed from the belt. As the sand is removed from the bunker through the gate 3, the bunker rises whereby the scrapers close gradually under the action of the counterweight and an increasing amount of sand is discharged from the conveyer belt.
