Abstract: 435,704. Cleaning photographic strip film. BARBER, J. A. A., and MASTERS, A. E., 6, Park Grove, Bromley, Kent. March 26, 1934, Nos. 9370/34 and 7503/35. [Class 98 (ii)] In a machine for cleaning strip film, e.g. kinematograph film, the film is passed through a bath of film cleanser, over fixed wiping devices, and through two rotary wiping devices the first of which is positively driven at a peripheral speed which is less than that of the second. The film supply and take-up spools are constituted by flanges B<1>, C<1>, secured on spindles B, C, and the film passes from the supply spool over rollers and wipers which, with the spools, are driven by an electric motor housed in a compartment E<1>. From the supply spool the film passes over a film guide comprising a roller R against which it is pressed by a roller R<1> mounted on a spring-biassed arm R<2>, and over a second guide roller R<4> to the cleansing bath M, which is divided by a partition M<2> into compartments M<3>, M<4> and is supported on pins M<1>. Immersed in the liquid in the compartment M<3> is a preliminary wiping device comprising a guide roller N<1> and felt pads N<2>, N<3> over which passes the film F to a roller O above the level of the liquid. The second compartment M<4> contains a guide roller O<1> under the liquid and above it a movable pad P<2> and two rollers P<1>, P<5> urged together by a spring, between which the film passes to the rotary wiping devices K, K<1>, J, J<1>. These devices are drum-like brushes mounted on horizontal axes and surfaced by strips of absorbent material, e.g. cotton. The brushes K, K<1> rotating in opposite directions dry the opposite faces of the film as it passes between them, and the brushes J, J<1> geared to rotate at a higher speed polish its surfaces. The film then passes over and under drying drums L<2>, L<1>, supported on brackets L and heated by lamps L<5>, and then over a roller S and film feeding sprocket H to the jockey roller S<1> and the film takeup spool. The spools are retained on the spindles by a longitudinally split sleeve which registers with a slit on the spindle and secures the spool by frictional engagement. 435,704.

Title: Improvements in or relating to the application of strip material to insoles
IPC: A43D43/06
Filed: 1943-06-19
Abstract: 567,465. Boots &c. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). June 19, 1943, No. 9910. Addition to 537,981. [Class 17 (i)] Insoles, machines for.-The rotatable means for applying reinforcing strip material to an insole in a machine as described in the parent Specification is driven instead of being freely rotatable. In a preferred form such means comprises a roll formed with gear teeth on that end which will lie nearer to the rib or lip of the insole, when the latter is in the machine, which teeth serve to drive the roll, preferably at a greater peripheral speed than the rolls which feed the insole. Tension on the strip at the point of its application is then relieved and distortion of the insole avoided. In the form shown, Figs. 1, 6, the strip-applying roll 40 has two parts 72, 74, one of which 74 applies tape to the part of the insole over the channel and base of the rib, while the other 72, which is slightly smaller in diameter, applies it to the body of the insole. The roll 40 is carried by an arm 42 on a rock shaft 32 and, on operation of the rock shaft by a treadle rod 36, it is brought into co-operative relation with the feed rolls 18, 22 for the insole. Simultaneously, the upper feed roll 22, which is carried on a shaft 20 supported in a yoke 28 pivoted at 30 to the head frame 10 of the machine, is yieldingly depressed, through a link 38 connected to the rock shaft 32, against an insole supported by the lower feed roll 18. The roll 18 is mounted on a shaft 12, and is driven by a belt 16 and pulley 14. A shaft 50 is driven from the shaft 12 through chain 58 and sprocket wheels 54, 56 at greater speed than shaft 12 and drives the roll 40 and teeth 74 thereon at greater peripheral speed than upper feed roll 22 and in the same direction through gear 70, and sprocket wheels 60, 64 and chain 62. The roll 40 is pressed against the rib of the insole. In a modification, the roll 40 may have teeth on the channel engaging part only, the remainder being smooth. In a further modification, the channel engaging part of the feed roll is mounted on a lever urged by a spring against the insole, the initial position of roll, amount of yield and tension of spring being adjustable so that it will engage the insole channel irrespective of variations in depth of such channel, as shown in Fig. 6. The upper feed roll 22 may have teeth or knurling on a part of its surface to increase grip on the insole further. Specification 555,063 also is referred to.

Title: Method of forming structural joints
IPC: E04C3/32
Filed: 1974-03-05
Abstract: 1452204 Structural bars; ladders R J REID 5 March 1974 [9 July 1973] 9947/74 Heading E1K and E1S [Also in Division F2] A joint between two elements, e.g. a rung 34 and a rail 10 of a ladder section, is formed by providing at least one flange 36 projecting from a face of one element and at least one elongate groove 14 on a face of the other element, the groove being of arcuate internal section and having a restricted opening 56 formed by lips 46, 48 allowing entry of the flange 36, after which pressure is applied between the two elements so that the flange deforms to form at least a portion of a coil within the groove, thus interlocking the elements. As shown, rail 10 has two grooves 14, 16 for receiving two flanges 36, 38 on the adjacent end of a box-section rung 34, the ends 62, 64 of the flanges being initially bent and rounded to provide a smooth initial engagement with the grooves. A machining process is preferably used to provide the flanges 36, 38 and at the same time to provide a tongue formation comprising a flat end face 74 and shaped side faces 115, 117 designed to fit tightly against corresponding surfaces 80, 116, 118 of the groove formation existing between the inner lips of the grooves 14, 16, when pressure is applied to tighten the joint assembly, as by pressing blocks (88-98, Figs. 4-6, not shown).  Extension ladders. The ladder shown in Fig. 1 consists of two pairs of rails 10, 12, the rails 10 being connected as described above to the rungs 34 to form one ladder section and the rails 12 being similarly connected to shorter rungs 40 to form a second ladder section. Sliding engagement between the two ladder sections is effected by cooperating flanges 22, 30 on the rails 10, 12, respectively, the rear face 42 of each rail 12 at the same time sliding on the front faces of the rungs 34. Metal columns. A tapering metal column is constructed from four pieces 106, 108, 110, 112, Fig. 7, each identical prior to assembly and comprising a L section member one arm of which has a continuous groove at its outer edge and the other arm of which has a continuous flange, the grooves and flanges being similar to groove 14 and flange 36 of the ladder described above. The pieces are pressed together, first to form two U shaped members, and then to form the hollow column shown, such that the flanges are caused to deform to a progressively greater extent, and hence coil to a progressively greater degree, from one end of the column to the other, so as to produce the taper of the finished column.
