Title: Mechanism For Piling Articles
Inventor: MARTIN DENNIS
IPC: B65G57/18
Filed: 1965-06-14
Abstract: 1,150,881. Stacking-apparatus; reciprocating conveyers. DAVY & UNITED ENG. CO. Ltd. 14 June, 1966 [14 June, 1965]. No. 24995/65. Headings B8A and B8C. A device for stacking elongate articles includes a platform 23 reciprocatable between a withdrawn position as shown, and a forward position above a table 33, detents 40 being provided to allow movement of articles on the platform 23 into the forward positionbut to strip the articles from the platform during reverse movement thereof, thereby depositing the articles on to the table 33. The backward movement of the platform may occur at a relatively high speed or a relatively low speed. In the embodiment described, elongate angle girders are carried to the device on a fixed roller conveyer 12 from which they are removed singly or in groups by dogs 15 travelling in rails 14 and fixed to an endless chain or rope conveyer 13. The girders are pushed by the dogs 15 to a position above the platform 23 in its withdrawn state, passing over a pivotal detent 30 on the platform. The dogs are then returned along the rails 14, the girders being retained on arms 24 of the platform 23 by the detent 30. The platform 23 is driven into its forward position, the girders pushing past the detents 40. When the platform 23 has been returned to its withdrawn position, leaving the girders on the table 33, a further layer is delivered by the dogs 15, and the process is repeated. The drive causing the withdrawal of the platform 23 from beneath each layer of girders may be rapid, in which case the girders fall directly on to the table 33 maintaining their original orientation, or slow, in which case the girders tip over through 180 degrees in falling, and if the withdrawals of the platform are successively fast and slow adjacent layers of the resulting stack nest into one another. If other forms of girder are being stacked the withdrawals may all be made rapidly, but the detents 40 may be moved by motors 41 in a direction parallel to that of the movement of the platform 23, so that alternate layers on the table 33 are displaced relative to one another, and nest in one another. After the stack has been formed the table 33 is lowered, depositing the stack on arms 36A of a trolley 36 running on rails 38. The trolley is then rolled from beneath the table 33, and the nested stack may be removed by a crane. The opposite end of the conveyer 13 may be provided with a similar stacking device, and for this purpose the dogs 15 may have two arms (16, 17), Fig. 2 (not shown), pivoted about an axis (15A) so that they can push girders in either direction.

Abstract: 1377530 Injection moulding machines BONE CRAVENS Ltd 8 May 1973 [30 May 1972] 25245/72 Heading B5A A reciprocating screw type injection moulding machine includes a drive piston 7 and cylinder 8 for effecting injection, the drive cylinder 8 being permanently connected to a fluid supply system to provide fluid pressure at all times during operation of the machine. As shown, pressure is supplied through lines 9, 10 to both sides of the piston. For injection, the pressure supplied through pipe 9 is much higher than that supplied through pipe 10. When a cut off valve 12 is opened, a pressure release valve 13 reduces the pressure in the rear of cylinder 8 so that the pressure difference across piston 7 is small. This pressure difference acts to oppose rearward movement of the screw 2. The pressures on the two sides of the piston 7 may be equalized prior to the start of screw rotation to effect decompression of the mould system. Pressure equalization may also be effected when the screw 2 reaches its rearmost position and prior to injection. The back pressure may be controlled by a closed-loop control system (not shown) in dependence on the condition of the plasticized plastics material.

Abstract: 712,396. Making paper bags KLEIN, E., KLEIN, H., and KLEIN, W., [trading as BISCHOF & KLEIN]. Oct. 20, 1950 [Oct. 22, 1949], No. 25568/50. Class 94 (2) A block bottom bag is formed from a blank that is scored along the fold lines in such manner that when formed into a flat tube by folding and glueing along lines corresponding to the length of the bag walls only, the ends of the tube open out automatically so as to facilitate the subsequent folding thereof. Fig. 1 shows a blank 1 with two parallel fold lines 2 and 3 on opposite faces and adjacent to the longitudinal edges of the web from which the blank is cut, and transverse fold lines 4 extending between the fold lines 2, the points 5 at which the lines 2 and 4 intersect forming the apices of obliquely extending fold lines 6. All the folding lines are scored in such a way that they facilitate the folding by biasing the individual parts of the bag in the direction in which they are to be folded, Figs. 2 and 3 (not shown). If the blank is formed of multi-ply paper or is otherwise difficult to fold, further scoring lines 16 may be provided. When the parts 9, 10 are folded inwardly about the lines 4, and pressed together in the area between the longitudinal lines 2. the bottom folds 11 spring up automatically and cause the end of the tube to open. as shown in Fig. 5. -The overlapping edges of the parts 9, 10'are glued together in known manner. Fig. 7 shows apparatus for making the bag, comprising a pair of rollers 18 which receive blanks severed from a supply roll (not shown) and form the longitudinal score lines 2, 3. Fig. 1. The scoring device may be arranged to omit parts 17 of the lines 3. Rollers 19 form the transverse and oblique score lines 4, 6 respectively, and may also form score lines 16, after which the blank passes between endless driving and guiding bands 20, 21 and is thereby brought against a grating 22 formed with an upwardly inclined front end 23 adjacent to a roller 24, the front portion of the blank being beneath a folding-bar 25- on the grating. The folding-bar 25 is no longer than the cross-folding lines 4 of the blank. The front end of the grating is swung downwardly into the position 29 indicated in broken lines, thereby producing a fold in the blank and positioning it between the pair of feeding rollers 24, 33 formed with peripheral grooves through which the ends of the rods of the grating 22 pass in swinging downwardly. The rollers 24, 33 feed the folded end 26 of the blank against a stop 36, where it is held momentarily by resilient devices 37. The other side of the blank is folded about the other line 4 by a folding blade 38 operated by levers 39, and the bottom part 11 of the blank becomes opened out. The blade 38 pushes the blank between the roller 33 and a co-operating folding- roller 42, and feeds it between a pair of cooperating endless bands 43, 44 associated with means for folding the block bottom in known manner.
