Title: Improvements in or relating to devices for opening shells of slide and shell cartons
IPC: B65B43/41
Filed: 1949-02-02
Abstract: 662,343. Packets-machines. HALL, C. T., and MOLINS MACHINE CO., Ltd. Feb. 1, 1950 [Feb. 2, 1949], No. 2895/49. Class 94(i) In devices for opening the shells of slide and shell cartons, in which the edges of a flattened shell are acted on by relativelymovable members one of which presents an interior angle into which the leading edge of the shell is guided upwardly by a ramp, the ramp is inclined at a fixed angle and means are provided whereby the ramp surface and shell may be brought into contact in the initial stages of the opening operation and withdrawn from contact as opening proceeds. In the machine shown, a shell S is fed from a magazine on to a bed 1, moved to the right by a pusher 2 and then pushed by an oscillatory tooth 3 into an opening device 4 comprising a pair of fixed ramps 5 inclined upwardly at 45 degrees and an L-shaped member 10 adjustable vertically according to the size of the shell on a bracket 9 secured to a slide 7 movable in a guide 6 inclined downwardly at 45 degrees. The vertical limb of the member 10 is slotted to provide clearance for the ramps as the member moves downwardly. The tooth 3 is oscillated by a cam 15 on a shaft 14 which is geared to a shaft 22 carrying a cam 23 engaging a roller 28 on lever 29 which moves the slide upwardly against the action of a spring 32, the roller 28 being adjustable in a slot 33, which is concentric with the shaft 22 when the slide is in its lowest position, whereby the stroke and speed of the slide may be varied to suit shells of different sizes. A second cam 24 on the shaft 22 operates top and bottom pressers 12 and 13 which bend the shell into shallow arcs to facilitate the opening thereof. The lowered position of the slide is determined by the engagement of the ramps with a horizontal limb of the member 10, the ramps then being directed towards the interior corner of the member. As the shell is pushed into the opener, its leading edge rides up the ramps into the corner of the member 10 which at the same time moves upwardly and to the left to disengage the edge from the ramps and complete the opening of the shell. In a modification, the member 10 is fixed and the ramps are carried on a member slidable along the bed. Specification 343,589 is referred to in the Provisional Specification.

Filed: 1953-02-05
Abstract: 724,794. Mixing appliances. WHITEHOUSE INDUSTRIES, Ltd., and KING, J. L. Feb. 5, 1953, No. 3223/53. Class 86. A measured quantity of liquid, such as oil, is introduced into a hollow body 1 through an inlet 8 and is mixed with another liquid, such as petrol, which flows through the body from an inlet 7 to an outlet 13. The liquids flow to the outlet 13 through aligned ports 16, 17 in a spring- loaded piston 15 and cylinder 14. The inlet 8 has a closure 20 which when opened to admit oil, automatically disengages a spring-loaded trigger 25 from the piston 15, thereby allowing the piston to slide under the influence of the spring 18 to close the passage through the ports 16, 17 and retain the oil in the body 1. When petrol is introduced under pressure into the inlet 7 it returns the piston 15 to the position in which a passage is opened through the ports 16, 17 and the piston is retained in this position by the trigger 25 until the next charge of oil is introduced through the inlet 8. Baffles 9 and 10 having perforations 11 in their outer and inner parts respectively, cause turbulent flow of the liquids. The device can be fitted to the flexible delivery pipe of a petrol pump beyond the delivery valve thereof.
