Title: Improvements in or relating to sheet feeding machines
IPC: B65H11/00
Filed: 1954-07-14
Abstract: 777,432. Feeding sheets. BACKHOUSE, H. T. July 13, 1955 [July 14 1954], No. 20605/54. Class 100(1) Feed tables; side registers:-A feed-table on to which a succession of sheets are fed or placed, and provided with side-lay means, is divided in its width into sections of which the outer one carrying the sidelay and its operating mechanism is laterally adjustable, and one or more of the others can be removed or replaced to accommodate such lateral adjustment of the outer section. The table may have eleven sections, six of whch are shown in Fig. 1, and the end section 16 at each side carries a side-lay mechanism 24. All the sections are slidable along cross bars 13, 14 and are arranged between side frame members 15 which are located between the main frames 10 of the machine. Each end section 16 is adjustable relative to the sides 15, along the bars 13, 14 by a screw and nut means. The second, third, and fifth sections 17, 18, 20 from each side of the table have forks which fit over the bars 13, 14 and rest on square cross bars 11, 12, and they are held releasably in position by spring detents. The fourth section 19 from each side carries a sheet slowdown device 35 and suction gripper conveyer 36. A front lay 37 is also associated with these sections.' The central section 21 is fixed to.the bore 13, 14. At the front of the table there are twelve independent supports 40 for the front edges of the sheets. These are keyed to a cross shaft and readily removable therefrom. The inner edge portion 48 of each section 16 is constructed separately, and is carried by two arms 49 slidable in guideways in the section for adjustment relative thereto. Each side-lay embodies a pair of friction rollers 51, 52, Fig. 9, and a smoother plate 55, for operation as described in Specification 688,137. To facilitate lateral adjustment of the lay the operating cams are slidable on a rotatable cross-shaft 59. These cams depress two lower pivoted arms which, through chains 64, 65, depress two upper pivoted arms; one of the latter, through a chain 70 and arm 72, partially rotates the roller 52 against the action of a return spring 74, and the other depresses the bracket 54 carrying the roller 51 by means of a chain 80 and spring 86. Specifications 427,041, 715,895, 716,880 and 777,431 also are referred to.

Abstract: 887,854. Electric-measuring instruments. HARCOURT Ltd., DAVID. June 3, 1960 [June 16, 1959], No. 20609/59. Class 37. [Also in Groups XIX and XXXVII]  A device for indi-  cating and/or controlling a variable, e.g. fluid pressure, temperature or electric current, comprises a pointer 2 which cooperates with a fixed adjustable contact 6 when the variable falls to a predetermined value. Initially, be-  fore subjection to the variable a pivoted stop 8 is raised by a setting arm 12 fixed to a spring- loaded, self-returning knob 10, to engage a notch 9 in pointer 2 to hold it away from contact 6. On subjection to the variable the pointer swings to the right allowing the stop to fall and the pointer to engage contact 6 should the variable fall to a predetermined value. The device is housed in a dust-tight housing, Fig. 3 (not shown).

Title: An interrupter for adjusting or rectifying electric currents
IPC: H01H29/00
Filed: 1929-07-05
Abstract: 333,022. Paul, M., and Wangemann, P. July 5, 1929. Commutator switching - arrangements. - An electrolytic switch for rectifying has rotary electrodes which can be immersed for varying periods. The spindle B carries electrodes A which rotate between the sections of the electrode D. Alternating current is supplied by the lead V, and the lead W passes from the electrode D to the directcurrent circuit. To vary the period of immersion of the moving electrodes, the level of the electrolyte may be raised or lowered, 'as, for instance, by the lowering or raising of a mass G. In a modification, a number of electrodes moving synchronously are employed; they can be adjusted in position relatively to each other and may be connected in series or in parallel. Separate cells for each phase are used when the apparatus is used to rectify three-phase currents. Each cell C<1>, C<2>, C<3>, as shown in Figs. 6 and 7, contains two rotary electrodes X, X<1>, Y, Y', Z, Z<1> respectively. Each pair is mounted at rightangles on two insulated shafts B', B<11>. The electrolytes are connected to the three-phase supply and the direct current is taken from sliprings on the shafts to the leads W, V.

[Class 94 (i)] [See also Group VI] To supply tobacco to a packeting-machine in the form of a " carpet," the tobacco is fed forwardly into one end of a confining passage having opposed surfaces for determining the thickness thereof and, after being fed through the passage, is removed from the opposite end thereof at a slower speed than that at which it was fed into the passage, the change of momentum of the tobacco, brought about by the reduction of its speed, causing a compacting of the tobacco shreds without the application of any ramming or positive pressure; the carpet thus formed has a thickness at least equal to the minimum distance apart of the opposed surfaces. Tobacco, withdrawn from a hopper by a carded roller in known manner, is showered either in a separated condition or as a carpet, on to a non-carded roller 9 which feeds it to a space defined by the roller 9 on the one hand and a roller 10 and guide plate 11 on the other hand, the space terminating where a more slowly moving carded roller 12 withdraws the carpet from the roller 9. In the space, the tobacco is compacted by the slowing- down operation which may be assisted by mounting the guide plate 11 on eccentric 16, 17 which move the plate towards, and in the same direction as the roller 12 but at a slower speed than that of the roller. A series of rollers may replace the guide plate or conveyer bands be used as the upper and lower surfaces or the lower surface only. Specification 249,575, [Class 130], is referred to.

[Class 87 (ii)] A stream of extruded clay, shale, gault or knotts is urged towards the observer at A, Fig. 6, by a reciprocating ram, and during the idle stroke of the ram one or more revolving knives 1 move (comparatively slowly) to the right from position B to position C, to sever the stream into lengths. The knives then move back (quickly) to position B and the ram extrudes more clay, the extruded stream pushing the severed length or lengths ahead of it on to a table 3 whence the lengths are removed by hand. The knives are adjustably mounted on a shaft 2 carried at the upper ends of rockable levers 7, 7<1>, pivoted at 6 and counterweighted at 9. The knives are rotated by means of an electric motor 10, pinion 11, spur-wheel 12, belt or chain 14 and pulley 15 on the shaft 2. The levers 7, 7<1> are rocked about the pivot 6, to and from the clay stream, by the mechanism shown in Fig. 1, in which 17 is a connecting rod which reciprocates the extrusion ram (not shown). The rod 17 is reciprocated by a crank formed of a large spur-wheel 19 and crank-pin 20, and this crank-pin carries a block or roller 21 which engages a slot 22 in a lever 23 pivoted at 24. As the connecting rod reciprocates, lever 23 oscillates about 24, and this oscillation is conveyed to levers 7, 7<1> by linkages 25 ... 30 to a pin 31 on the levers. The amount of clay extruded at each stroke may be greater than the length cut off, the waste dropping into a shoot 4.
