Title: Improved container for storing record cards or anything in sheet or laminar form andthe like
IPC: B42F7/14
Filed: 1948-04-29
Abstract: 653,082. Filing papers. MILLAR, G. April 29, 1948, No. 11816. [Class 146 (i)] A container for filing record cards, sheet or the like comprises a base with fixed ends, a pivoted front with a hinged link at each end, each link having a hooked slot to engage a fixed stud, and a pivoted back having similar links with hooked slots which engage the same studs. The base is formed from a plate of rigid material with ends bent upwards and the tops bent outwards to form handles C. The base is raised either by strips of wood (Fig. 23) secured to the front and back edges or by the front and back edges being curled underneath (Fig. 9) and the front D and back E may be hinged to the base or have bent edges passing through slots Q in the base and either held as in Fig. 9 or by a pin passing through the edges which are curled over. The base may also be provided with a series of slots W parallel to the front in which dividing plates are pivoted by tongues Z, Fig. 15 (not shown), passed through the slots W and held by rings S, the angle of movement of each plate being about 30 degrees either side of the vertical and limited by projections B resting on the tops C of the fixed ends. The dividing plates may have holes to reveal contents behind and also to lighten the plate. The hooked slots R in the end links co-operate with the stud P to limit the movement of the front D and back E to about 30 degrees, the links either dropping by gravity, or spring constrained, so that the stud P enters the hook to hold the front or back in the vertical position. To release the stud from the hooks, a release plate (Fig. 23) is provided under the links having a vertical slot and bent lower edge by which the links may be raised. The front and back hinge to the base may be set inwardly from the edges of the base and in this case and when slots Q are used, the fixed ends may have projections F which protrude through slots in the front and back. The ends and front and back may be provided with card frames T.

Patent GB-353026-A (GB)
Title: Improvements in means for periodically changing the direction of rotation of a shaftor other rotating body
IPC: F16H3/00
Filed: 1930-04-17
Abstract: 353,026. Reversing-gearing for dyeing-machines &c. LEE, T., Edge Moor, Woods moor Lane, Stockport, Cheshire. April 17, 1930, No. 12253. [Class 80 (ii).] Means for periodically changing the direction of rotation of a shaft or other rotating body, e.g. the propeller of a dyeing-machine, comprises a clutch member 10 adapted to travel automatically along its shaft 9 in either direction according to the direction of rotation imparted thereto by and during the rotation of the shaft 1 under control, the clutch member 10, at the end of its travel, causing partial rotation of one of a pair of clutch members 11, 12 each fast with a ratchet wheel 13, 14 which positions a gravity operated device 27, 30 adapted to actuate the reversing means 29. As applied to the propeller shaft 1 of a dyeing-machine driven by means of open and crossed belts 5 on loose pulleys 3, 4 and a fast pulley 2 mounted on the shaft 1, the rotation of the shaft 1 is transmitted through reduction gearing 6 to a shaft 8 having a helically splined boss 9 on which a clutch member 10 having notched teeth at each side is secured. The clutch member 10 may engage one or other of two toothed clutch members 11, 12 integral with ratchet wheels 13, 14 respectively, the ratchet wheel 13 being twice the diameter of the wheel 14 and its teeth directed oppositely to those of the wheel 14. Pawls 15, 16 engage the teeth of the ratchet wheels 13, 14 both pawls pivoted at 17 on a rod 18 which is pivoted at 19 and is connected by a rod 20 with a bar 22 carrying, at its upper end, a weight 30 and being pivoted at its lower end 23. A pin 26 on the rod 22 moves in a vertical slot 25 in a shipper rod 27 which operates belt moving forks 29 engaging the belts 5. Drive from the shaft 1 rotates the shaft 9 and with it the clutch member 10 which is restrained by the friction caused by the pressure of a spring 31 on its periphery. This resistance causes the member 10 to move along the helix of the splines on the shaft 9 in one or other direction, depending upon the direction of rotation of the shaft 9 and hence of the shaft 1, and to engage one or other of the clutch members 11, 12. The member 10 now rotates with the shaft 9 and the corresponding ratchet wheel 13, 14 is given a partial rotation which operates, through the corresponding pawl 15, 16 and the levers 18, 20, 22, to move the shipper rod 27 into the neutral position when the weight 30 is just past the vertical position. At this point the weighted lever 22 falls over to the extreme position and moves the shipper rod correspondingly so as to reverse the rotation of the shaft 1. The action is then repeated. The time intervals between successive reversals is determined by the diameters of the ratchet wheels 13, 14 since the time taken to rotate the greater circumference of the larger wheel 13 sufficiently to move the shipper rod to the neutral position is less than that taken to rotate the smaller wheel through the same distance. Specification 353,027, [Group IV], is referred to.
