Title: Improvements in or relating to cleansing machines for bottles and other vessels
IPC: B08B9/36
Filed: 1951-08-07
Abstract: 698,370. Cleansing bottles &c. SEITZWERKE GES. Aug. 7,1951 [Aug. 9, 1950], No. 18546/51. Class 138 (1). A machine for cleansing bottles &c. of the type having internal and external brushing elements is provided with a lifting device which moves the bottle, positively 'relative to the internal brushing elements into an after-rinse position wherein it may be gripped for removal from the machine, a supply of after-rinse water being shut off through a controlling device solely on displacement of the bottle beyond said afterrinse position during said removal. The machine comprises, a twin-armed lever 25, pivoted at 29 and provided with forks 26 at its ends to grip the mouths of bottles 23, 24, brushes 10, 11 for cleansing the interiors of the bottles, an external brush roller 14 (the bristles of which are omitted), fixed side brushes 18, 19 and base brushes 15 for cleansing the bottle bottoms. The brushes 10, 11 and 14 are rotated by a driving mechanism 30 and impart rotation to the bottles by friction. Water is supplied to the base brushes 15 and brushes 10, 11 through two pipes 20, Fig. 2, each under the control of a valve 21. The brushes 15 are fixed to levers 16 pivoted on a shaft and each lever 16 has a counterweight 17 and a cam 22 for controlling the respective valve 21. In the position shown in Fig. 1, the bottle 23 has been depressed for cleansing by brushes and water whilst the bottle 24 has been simultaneously raised for rinsing. The elevation of the bottle 24 is not sufficient at this stage to cause the cams 22 of the associated lever 16 to close the valve 21. When the bottle 24 is gripped manually and raised beyond this position the lever 16 and its cam 22 also move to shut the valve 21. A fresh bottle may then be inserted and pushed down over the brush 11 for cleansing. Simultaneously the bottle 23 is then raised to the rinsing position. The supply of rinsing water is again cut-off when the bottle 23 is raised further during its removal by its associated cam 22. In a modification the twinarmed lever 25 is tiltable by a hand lever while in a further modification the levers 16 are connected by push bars to the lever 25. In this case the push bars have lost motion connections with tne levers 16. The levers 16 may be moved mechanically by the machine drive, the movement of the lever 25 then following in a definite rhythm.

Abstract: 693,372. Corrugating. NAPIER & SON, Ltd., D. July 24, 1951 [July 25, 1950], No. 18563/50. Class 83 (iv). Apparatus for corrugating a tube comprises two sets of spaced corrugating rollers 11, 12, each set comprising two or more rollers in the form of a disc having a peripheral ridge for forming a single corrugation, the sets of rollers being mounted respectively on two parallel shafts 13 and 14 arranged so that the wall of the tube can lie and be rolled between them and means for moving the shafts towards one another and for rotating the tube, the rollers being axially movable along the shafts and separated by resilient distance-pieces 17, e.g. rubber washers, to enable the rollers to close up along their shafts to allow for the shortening of the tube due to the corrugating operation. The rollers 12 are freely rotatable on the shaft 14 and the rollers 11 are splined on the shaft 13 which is driven. The ends of each shaft 13, 14 are eccentrically supported in toothed discs 19 and 20 respectively which mesh with each other and are supported in end-plates 21, 22. To move the shafts towards or away from one another the discs are rocked by means of a manually rotated shaft 23 carrying pinions 24 which mesh with the discs 20. The shaft 13 is supported between the headstock 26 and tailstock 27 of a lathe whilst the end plates 21, 22 rest on a bar 28 placed in the V-ways 29 of the lathe bed. In operation, a tubular metal blank is placed over the rollers 11 by first withdrawing the shaft 13 from the lathe. The shaft 13, rollers 11 and the blank are then rotated and the corrugations formed in the blank by moving the shafts 13 and 14 towards one another. The corrugations may be formed in stages by using progressivelyshaped rollers and the tube may be annealed between stages. End pressure may be exerted on the tube by means of a rack 30 supporting a sliding carriage 31 which carries a pinion engaging the rack and which is rotated by a handle 32. The carriage has a pillar 33 projecting between the shafts 13 and 14 and bears between two shoulders 35 of a yoke 34 formed with two opposed U-shaped arms which bear against two collars 38, 39 on the shafts 13 and 14 so that end thrust can be applied continuously while the distance between the two shafts is being varied. In addition, the shaft 13 carries two freely-supported and eccentric rings 42, 43 which fit against the ends of the blank. End thrust is exerted on the rings by two link pieces 44, 45 freely mounted on the shaft 13 and formed with extensions 46, 47 shaped to engage collars 48, 49 on the shaft 14. A roller 50, 51 is mounted on a radial spigot on each link-piece 44, 45 and bears against the outer surface of the ring 42, 43. Two further shaping rollers 52, 53 are carried on the shaft 13 adjacent the rings 42,43.
