Title: Improvements in or relating to machines for interfolding sheets of paper
IPC: B65H45/24
Filed: 1937-07-13
Abstract: 476,036. Interfolding paper sheets. LERNER, F. July 13, 1937, No. 19389. Convention date, July 14, 1936. [Class 100 (i)] In a machine for interfolding prefolded sheets of paper 19, e.g. cigarette papers, by means of toothed wheels 16, 17, and for inserting sheets of cardboard 18 at predetermined intervals, each group of sheets with its sheet of cardboard is separated from the succeeding group by means of a toothed disc 9 situated adjacent to the outer edges of the sheets 18, 19 in the grooves on one of the sheets 16, and rotating at relatively high speed so that when it engages the stiff cardboard sheet it moves the sheet 18 and corresponding sheet 19 against the opposite face of the groove carrying the sheet, thus preventing interfolding at this point and causing separation of the adjacent groups. The turning action of the disc may be supplemented by an endless band 11 passing over a pulley on the shaft of the disc 9.

Title: Improvements in or relating to photographic roll film cameras
IPC: G03B17/42
Filed: 1936-07-17
Abstract: 472,563. Photographic cameras. ZEISS IKON AKT.-GES. July 17, 1936, No. 19929. Convention date, July 17, 1935. [Class 98 (i)] Two tiltable levers hinged to one another are provided between the shutter-operating means and the combined film feed and shutter winding means of a photographic camera so that actuation of one of said means effects a release of the locking of the other means and thereby becomes itself locked. A lever 18 pivoted at 20 to the camera, and also by means of a bolt 17 to a lever 19, is attached to a fixed point 22 by a spring 21. The lever 18 has noses 24, 27 for locking the film feed and shutter winding member 29 and the shutter release member 15 respectively. When the shutter release is held by the nose 27 and the member 29 is moved, a wedge 16 engages the bolt 17 and swings the lever 18 about the pivot 20 over the dead centre, so that the nose 24 rests on the member 29. The member is released from the nose 27, and after completion of the actuation of the member 29, the lever 18 locks the end 25 thereof. When the shutter release 15 is actuated, the stop 26 engages the lever 19 and swings the lever 18 over to a position with its nose against the surface 28 of the release member 15, thereby releasing the member 29. When the member 15 returns, the nose 27 engages the stop 26 and prevents actuation of the shutter until the film has been advanced again and the shutter tensioned. A disconnecting device 30 may be introduced to enable a plurality of successive actuations of either of the members 15, 29. The device 30 has an end 31 and a stop 34 with an inclined surface 32 adjacent the surface 28 of the release member. When the device 30 is depressed, the end 31 engages the lever 19 and holds over the lever 18, thereby permitting successive operations of the member 29. Since the inclined surface 32 can engage the surface 33 of the lever 18 and move away the locking nose 27 when the release member is actuated, a succession of operations of the latter can be made when the device 30 is depressed. The lever 19 is engaged by the member 15 and moves about its pivot bolt 17 against the action of a spring 36. The Specification also comprises the subject-matter of Specification 463,769:

Title: Improvements in hoisting engine control mechanism
IPC: B66B5/08
Filed: 1919-08-14
Abstract: 152,466. Lilly, W. J. Aug. 14, 1919. Overwinding and overrunning, preventing.- Relates to governor-controlled end-stop-gears for hoisting-engines having an electrical system controlled by the position and speed of the cage and provided with means for warning the engineer, stopping the engine and variably applying the brake. The governor controls a rocking switch, co-operating with cams on parts rotating in unison with the winding drum and thus synchronising with the traverse of the cage, and connected to electric circuits by which a warning-bell is rung, the brakes are applied and the engine throttle-valve is closed. The governor 40, Fig. 2, controls the position of a pivoted rocking switcharm 56<a> carrying connexions 53<c> to a solenoid, battery and bell and having spring contacts 52a, the lower contact 52 being adapted to be disengaged by a rocking arm 50 when the arm is raised by cams 46 on a disk rotated by the winding-drum in unison with the traverse of the cage. The arrangement is such that with the cage rising at normal speed, the contact 52 is in proximity to the rocking-arm 50. If over-speeding occurs the contact is moved by the rocking-arm and the bell rings. If the engineer does not reduce the speed, further movement of the switch-arm 56a actuates a solenoid 69, Fig. 6, and through trip mechanism 100 releases a weighted arm 104 which closes the throttle-valve and applies the brake, through linkage 9 and 86, respectively. When approaching the top landing at normal speeds a cam closes a circuit to ring the bell and if no action is taken by the engineer the governor-controlled trip mechanism acts as before. A quick-action trip mechanism for use when the cage approaches or passes the top or bottom landing comprises a cam 58 which strikes a pivoted arm 59 and causes a second cam-actuated arm 60a to operate the governor switch-arm and release the trip mechanism. The brake action is varied according to the speed of the cage by means of a roller 78, Fig. 6, and linkage SO controlling a rocking-stop 81. With the stop vertical, as shown, overspeeding of the cage and the release of the trip-gear causes the arm 82 to strike the stop and the linkage 86 to operate the brake-engine valve-lever 91 to apply the brakes gradually. If the cage is not stopped at the landing a cam 77 strikes the roller 78 and dislodges the stop 81, the lever 82 descends further and the brake-valve is opened more widely. An auxiliary end-stop gear for the top landing comprises pivoted arms adapted to be struck by projections on the cage, the arms being linked to a sliding switch in circuit with the solenoid controlling the trip mechanism.
