Mechanism for interlocking a locking tab 59 in one panel with a retaining tab 63 in another panel, e.g. in securing wrap-around cartons, comprises means for moving the panels along a predetermined path and a rotary element having radial tab-engaging elements 98 arranged to engage the locking tab 59 and drive it against the retaining tab 63 and through the opening defined by said retaining tab, the rotary element being mounted for rotation about an axis 94 which is angularly disposed to the planes of said panels so that the locking tab is caused to swing through a predetermined angle whilst causing said retaining tab to swing through a smaller angle during a locking operation, the two angles being such that the free end of the locking tab is caused to swing past the free end of the retaining tab, so that the locking tab is braced at an angle to the panels by the retaining tab when the radial element is withdrawn from engagement with said tabs. In the embodiment suitable carton blanks as shown in Fig. 2 and comprising a panel 25 having fingergripping apertures 26, 27 and article-engaging apertures 28-33; sloping corner-forming panels 34, 35; side walls forming panels 38, 40 and bottom-forming panels 48, 51 having apertures 46 for locating the bottoms of said articles and retaining tabs 60-63 and locking elements 56-59 respectively, are removed singly from hopper 7 by a reciprocable suction plunger 14 and placed over a group of articles, e.g. bottles fed into the machine by suitable conveyer means. Each blank is supported on and transported by hooks 20 on an endless conveyer 15, in synchronism with a group of articles such as B1, B2 &c. urged along by plungers 13 on a conveyer 8. Each assembly of articles and associated carton blank, are then conveyed past suitable folding mechanism (plough 66 only shown) to wrap the blank around the articles in known manner. The bottom panels are brought into overlapping relationship and with the respective retaining tabs and locking elements in register. The blank is tightened around the articles by tightening elements such as 83, 84 engaging tightening apertures 52, 55 and the locking elements (59 shown) are pushed past the retaining tabs (63 shown) by a rotating element having a number of tab-engaging elements 98. The rotating element is driven by a chain 103 and is mounted on an axis 94 angularly disposed to the plane of movement of the bottom panels so that the locking elements are pushed through an angle in excess of 90 degrees whilst the retaining tabs are pushed through an angle of less than 90 degrees so that as the tab-engaging element 98 is withdrawn the elements and tabs spring together and positively engage. The pitch circle point on each tab engaging element 98 at which the instantaneous velocity is substantially equal to the velocity of the panels is arranged to be about half-way between point of maximum penetration and the plane of the tabs.

Abstract: 1437234 Hand-operated brake valves controlling spring-applied compressed-air-released brake cylinders ROBERT BOSCH GmbH 10 Oct 1973 [11 Oct 1972] 47218/73 Heading F2F A hand-operated brake valve assembly actuable by a lever 4 to control the pressure in a line 28 connected to spring-loaded brake cylinders comprises a double seat valve consisting of an inlet valve 19, 20 operable to connect the cylinders to a supply of compressed air via a line 13 and an outlet valve 19, 22 operable to connect the cylinders to atmosphere via a passage 30. The sealing surface 19 is formed on a valve closure member 18 inserted into an actuating piston 8 which itself is formed with the valve seat 20 while the valve seat 22 is rigidly connected to a valve stem 23 movable by actuation of the lever 4-pivotal movement of the lever 4 is converted into longitudinal movement by a cam control arrangement 3<SP>1</SP> which longitudinal movement is imparted to an adjusting screw 6 screwed into a body 5 of plastics material. To release the brakes the line 13 is charged with compressed air, which air enters an annular chamber 10 defined by a skirt of the piston 8, the chamber 10 acting as a floating supply chamber since it moves back and forth with the piston 8. The compressed air enters a chamber 26 via open inlet valve 19, 20 and then flows to the cylinders via line 28, the valve 19, 20 being held open by the action of a spring 25 on the outlet valve seat 22 to urge the seat 22 against member 18 and thereby close valve 19, 22. As the pressure increases in the cylinders to cause brake release the piston 8 moves upwardly against the action of a strong graduating spring 15, the seat 18 and the stem 23 moving with it until at a predetermined brake release pressure the stem 23 abuts the screw 6 and the members 18, 22 are held stationary; the piston 8 moves upwardly a short distance until the inlet valve 19, 20 closes. This arrangement prevents unnecessarily high release pressures in the line 28. To apply the brake the lever 4 is first pulled to release a catch 31 and is then rotated to move stem 23 downwardly to open valve 19, 22 whereby the brake-operating cylinders are vented. The value of the release pressure may be altered by adjustment of the screw 6 to alter the loading of spring 15, the screw 6 being accessible after removal of a cover 3.

Abstract: 1,169,198. Flash-removal. A. T. RANSON (Owens-Illinois Inc.). 26 Oct., 1966, No. 47949/66. Heading B5A. Flash is removed from moulded articles e.g. blow-moulded bottles, along the line of juncture by locating the article into a spaced relationship with a die having a planar edge conforming to the line of juncture of the flash and with the line of juncture on the article spaced from the die edge, advancing the article to engage the die, advancing a knife having an edge conformed to mate with the die edge to sever the flash. As shown in Fig. 2, the apparatus may comprise two die/knife assemblies to deflash the article, which has flash asymmetrically disposed about it e.g. a handled bottle, in two stages. The apparatus comprises a conveyer 38 which passes through a preorienting station (Figs. 11, 12, not shown) to orient the bottle thereon so that the plane of the flash is at #45 degrees to the direction of movement of the conveyer. Feeding of bottles to deflashing apparatus is controlled by rods 108, 110, 112, of motors 100, 102, 104, Fig. 4. When stopped by rod 112, the bottle is moved by plates 78, 86 by means of motors 70, 72 on to platform 60 while moving upwardly by means of motor 64 until it engages face of handle die (202) on carrier 154, preventing further upward movement of platform 60, the flash contacting the handle die face first causing rotation of the bottle and platform 60 together until the line of juncture is in congruence with the die edge (208, 210, Fig. 5, not shown). Knife edge (222, 224, Fig. 6, not shown) on carrier 156 is advanced by motor 158 to mate with die edge (208, 210) to sever the flash. After retraction of knife assembly, die 202 is retracted by means motor 168, acting through cam 164, and return spring 162.
