As shown, box blanks 2 and corrugated liner blanks 8 are fed out of phase by devices 1, 1a and conveyers 3, 7 to double-belt conveyers 4, 9 respectively. The double-belt conveyers, which may move at different speeds, comprise belts 5, 6 and 10, 11, so disposed that belts 5, 11 bring the blanks into contact. Belt 10 is adjustable in length by rollers 13, 14. The blank 2 may be pre-folded on conveyer 4 and is preferably glued on leaving belt 6. Endless chains 16 are driven by toothed wheels 17, 20, 21 and are provided with series of lays 25, 26 (see Fig. 2) for contacting blanks 2, 8, respectively; whichever blank touches its lay first is restrained from further movement so that the other blank slides thereon until restrained by contacting its own lay. Lays 25 are connected to the chain 16 via axles 27, 30 and connecting rods 29. Lays 26 are similarly connected via axles 35, 39 and trapezoidal plates 33, which are bent at the bottom to define a track in which the position of lay 26 is adjustable relative to lay 25 (see Figs. 4-6, not shown). The belts 5, 11 are pressed together between adjustable rollers 42 and fixed rollers 43 (see Fig. 7). The rollers 42 are carried on a beam 46 which is suspended from braces 47, 48 whose position can be adjusted by a screw 51 (see Fig. 3, not shown). The positioned blanks may be subsequently folded and, if not already glued, may be connected together, e.g. by stitching.

Title: Screw press
IPC: F16D31/04
Filed: 1974-01-31
Abstract: 1423792 Screw press W BRAUER 31 Jan 1974 [31 Jan 1973] 04635/74 Heading B3H A screw spindle press has a push member 3 carrying a working tool and driven by a rotatable mass 12 which is selectively coupled to the spindle 5 of the press by a hydrostatic coupling. The spindle engages with a nut 4 held against rotation in the push member 3 so that the push member moves axially as the spindle is rotated. The hydrostatic coupling is a gear pump with a middle wheel 7 keyed to the spindle in mesh with pinions 10 spaced around the middle wheel and mounted on the pump housing 11. The housing is rotatable and rigidly connected to the mass 12 which acts as a flywheel. The housing and/or the flywheel carry rotor bars 13 of an electric motor whose stator 14 is fixed to press frame. The return stroke of the push member 3 is effected by hydraulic rams 18 which are pressurized during the downstroke. The pump is supplied with fluid between its intake and delivery sides under the control of a magnetically, hydraulically or compressed-air operated valve. When the valve is closed the fluid flow between the intake and delivery sides of the pump is blocked and a pressure is established in the pump which prevents the pinions 10 rolling on the middle wheel 7. Thus the spindle is rotated by being coupled hydrostatically to the flywheel. The valve is opened rapidly at the end of the working stroke by the consequential pressure rise.

Abstract: 964,637. Epicyclic gears. FICHTEL & SACHS A.G. Feb. 5, 1963 [Feb. 7, 1962], No. 4701/63. Heading F2D] In a two-speed epicyclic gear cycle hub the ratio changes are made automatically at predetermined speeds by centrifugal balls 32 operating an axially movable sleeve 17, the upshift and downshift speeds being slightly different to avoid hunting. As shown the gear unit consists of a sun pinion 29, planets 5 and annulus 6, drive being transmitted from a sprocket 43 to the hub 2 through a coupling sleeve 7 and pawl-carrying sleeves 10, 12. As speed increases the balls 32 move outwards, forcing the sleeve 17 to the right against a loading spring 23 until a circumferential slot 24 in the sleeve allows the passage of a pawl 16, carried by a ring 15, to engage teeth 18 on a hubdriven member 26 and thus rotate ring 15 and an integral shift cam 27 to introduce the high gear setting through members 13, 14. With decreasing speed a second slot 25 slightly offset from slot 24 allows pawl 16 to again operate and cause the unit to revert to the low gear setting, the offsetting of the slots ensuring that upshift and downshift occur at different speeds.
