Title: Improvements relating to the manufacture of box blanks
IPC: B65D5/28
Filed: 1933-03-01
Abstract: 394,932. Manufacturing boxes and blanks therefor. LINDGREN, A. G. S., 14, Rosenlundsgatan, Gothenberg, Sweden. March 1, 1933, No. 6239. [Class 18.] A method of manufacturing a box blank 6 consists in shaping cardboard or like material and providing it with slits 11 and creases 10, 13, 14 to form foldable sides 8, 9 and flaps 12, 15 and coating it on one surface and at one operation with a solution which has the property that coated parts stick to other coated parts without being moistened or softened but not to uncoated parts, the shape of the blank and the disposition of the coating being such that when the blank is erected to box form the parts to be fastened together present surfaces which mutually adhere. On one surface of the blank the flaps 12, outer parts 15 and possibly also the sides 9 are provided with a coating such as 16, 17 or as 16a, 16b, 17a, 17b. When the sides of the box are erected, the flaps 12 turned inwardly and the extension 15 inwardly and downwardly, the mutually contacting coated portions such as 18, 19 stick together. The dispositions of the coatings may be suitably varied. The adhesive is preferably applied by feeding the blanks in contact with rollers which dip into the solution, and which are preferably spaced from the edges of the blank so that the adhesive does not run over the edges. The solution consists of a solution of rubber in benzole.

In the preferred embodiment the paper is coated with an aqueous emulsion containing a water-immiscible volatile organic liquid, a higher carboxylate (i.e. containing more than 8 carbon atoms) of a polyvalent metal whose sulphide is colourless, an alkali metal sulphide and an acidic manganese salt in amount sufficient to produce acidity in the emulsion, the sheet is dried and the coated surface is coated with another aqueous emulsion containing a water-immiscible organic liquid and a higher carboxylate of a metal whose sulphide is dark, and again drying the sheet. The transferred writing, &c., is made visible by treating with dry ammonia gas. In examples, paper is first coated with an aqueous emulsion containing manganese nitrate, potassium sulphide, carbon tetrachloride and aluminium palmitate, and after drying is coated with an aqueous emulsion containing carbon tetrachloride, aluminium palmitate and (1) lead nitrate, or (2) silver nitrate, manganese nitrate and shellac. The aluminium palmitate in example (2) may be replaced by aluminium chloride and other light coloured natural or synthetic resins may be used instead of shellac. Other ingredients specified are :-immiscible organic liquids-benzene and toluene ; metal salts -aluminium, calcium and zinc salts of stearic, naphthenic or other resin acids, lead palmitate and water-soluble salts of lead, silver, tin (stannous) and bismuth, e.g. basis lead acetate.

[Class 78 (iv).] A. lifting-cradle for handling removable vehicle bodies comprises a braced frame 10, 11, 12, Fig. 3, with a pivoted shackle 40, Fig. 7, at each corner to engage hooks a<2> on the vehicle body, and power devices for operating all four shackles simultaneously. The frame carries a platform 14 to enable one operator to attach the lifting eyes 35 to the crane hook and these eyes are carried on articulated links 32, 30 so that the crane hook may be brought within reach. The cradle is guided into position by cam plates 22, 23, Fig. 7, which engage the side and back of end hook a<2>. In the form shown in Figs. 3, 4, 7 and 8 the shackles 40 are normally held in the loadengaging position by weighted arms 45, and are moved about their pivots into the disengaged position by fluid-pressure devices. The piston 60, Fig. 4, is moved for this purpose by a hand-rope and a lever 70 against the action of a spring, and forces oil through a check-valve 64 to the four conduits 55 leading to the four cylinders 81. The cylinder 52 of the piston 60 is in communication with the oil reservoir 51 through a port 53. Each cylinder 81 is pivoted on a bracket 80 on the cradle, and the shackles are connected with plungers 86 in hollow pistons 84 so that the shackles can be moved by hand independently of the pistons. An extensible dust-proof cover 88 connects the plunger and the cylinder. The shackles are allowed to engage the hooks by releasing the operating lever 70. the oil returning freely from the conduits 55 to the cylinder 52 by lifting the disc 62 which carries the valve 64. The conduits 55 are run through protective piping 90, 91, 92, Fig. 3. In modifications, Figs. 9 to 11 (not shown), the shackles and the cylinders 81 are carried on fittings slidable along the side bars of the cradle to suit vehicle bodies of different lengths ; the shackles may be moved individually and secured in selected positions by pins, or they may be moved by screw-and-nut mechanism from a single hand-crank. To suit vehicle bodies of different widths, double shackles 147, 148, Fig. 14, may be provided, the guides on the cradle being suitably modified. If desired the shackles may be biassed by springs or weights towards the disengaged position, the power mechanism bringing them into engagement with the hooks. As shown in Fig. 15, the shackles are moved in both directions by solenoids. Each shackle 40 is connected by a link 185 with the core 180 of a double solenoid with windings 171, 172, which are energized separately for moving the core in opposite directions. The link 185 may carry limit switches, Fig. 16 (not shown), for de-energizing the solenoid winding when the movement of the shackle in either direction is completed, and a spring stop for holding the link in either extreme position. The solenoids are controlled simultaneously from a common switch. Specification 374,845 is referred to.

[Also in Groups X and XIV] A plurality of flexible shafts 22, Fig. 1, par. ticularly for adjusting vehicle seats and windows, are adapted to be selectively operated from a drive unit 24 including a single reversible drive motor 26. The unit 24 comprises shafts 106, 108, 110, to which the flexible shafts 22 can be coupled at both ends and which are adapted to be driven from the motor mounted at 96 through gearing 112, 100, 102, 104 and clutches 114. Each clutch 114 comprises a sliding sleeve 114, see Fig. 13, on its shaft adapted to engage a dog clutch element 118 secured to the respective gear free on the shaft when actuated by a solenoid 120. The remote ends of the flexible shafts 22 have worms meshing with worm-wheels driving pinions in mesh with racks for actuating the seat or window. As applied to a vehicle seat one pair of shafts 22 effect the fore-and-aft adjustment of slide member 12, Fig. 3, in fixed tracks 10 by the pinion 30 carried by a side frame 16 of the slide 12 engaging the rack 32 pivoted to a fixed member 35 at 36. For vertical adjustment of the rear of the seat a pinion 54, Fig. 5, engages a rack 56 pivoted to a lever 48 which is in turn pivoted to the side frame 16 at 50. A link 44 pivoted at 52 to the lever 48 is also pivoted at 46 to a seat support member 20. Thus movement of rack 56 will raise or lower the rear of the seat about a front pivot 40. A similar arrangement is provided for adjusting the front pivot 40 of the seat.
