Title: Improvements in inking apparatus and the method of operating the same
IPC: B41F31/14
Filed: 1932-05-06
Abstract: 403,990. Inking-apparatus. SCHLESINGER, A., 23, Spenerstrasse, Berlin. May 6, 1932, No. 13103. [Class 100 (ii).] The inking-apparatus of a printing-press is arranged so that the ink on its way from the duct roller to the distributing- rollers is passed into a number of sets of rubbing-apparatus movable as a unit wherein the ink is thoroughly mixed and heated to increase its fluidity. In one form, the rubbing- apparatus unit is carried by a frame 18, Fig. 1, arranged to rock about a shaft 17 through the action of a cam 25 on the plate cylinder 28. The frame 18 carries two pairs of rollers 38, 39 and 40, 41 arranged so that when one of the rollers 38 or 40 contacts with the duct roller 2, the roller 41 or 39 respectively engages with the distributing-roller 7. The rollers 38-41 are rotated by a common gear-wheel on the shaft 17 driven from the shaft of the roller 7. In a modification, an apparatus for transferring ink from the duct roller to the rollers 38, 40 is interposed between the duct roller and the unit 38-41. The apparatus comprises a roller 50, Fig. 3, mounted on a bell-crank lever 51 rocked by means of a cam 48 on the plate cylinder. The roller 50 is in contact with a second roller 59 carried by the lever 51 and continuously rotated from a shaft 63 which also actuates the distributing-rollers 7, 34. Rotation of the plate cylinder from the position shown first causes the roller 50 to be rocked into contact with the roller 38 due to the action of the low part n<1> of the cam 48. Later the high part h<1> of the cam rocks the lever 51 to cause the roller 50 to engage the intermittently-rotating duct roller 2. The duct roller tends to rotate the roller 50 and so causes a rubbing of the ink between the rollers 50, 59. At this time, the frame 18 is rocked by the cam 25 to bring the roller 39 into contact with the roller 7. Further rotation of the plate cylinder rocks the roller 50 into an intermediate position, due to the action of the part m<1> of the cam 48, in which position the roller 50 engages the roller 40 of the rubbing- apparatus. In a further modification, the roller 50 is in engagement with the roller 59 only in its intermediate position. To increase the rubbing and heating effects, the rollers 50, 59 may be axially shifted relatively to each other, or they may be connected by gearing, arranged to give different peripheral speeds thereto.

Patent GB-560206-A (GB)
Title: Improvements in and relating to pressure switch mechanism
IPC: H01H35/24
Filed: 1942-09-24
Abstract: 560,206. Actuation of switches. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 24, 1942, No. 13445. Convention date, Sept. 26, 1941. [Class 38 (v)] In a pressure, temperature or other conditionresponsive switch, the pressure acts through a bellows 51 or other device on a lever 28 mounted in a channel frame and having a finger 30 passing out through a hole in the frame to operate-the switch. The lever 28 acts against the bias of two springs 60, 83, one spring 60 being alone effective as the switch moves into one position but both springs acting additively as the switch moves into its other position. Thus the switch may be opened when the pressure round the bellows exceeds the combined effective pressure due to the two springs and may be closed when the pressure falls below that due to the spring 60. As the pressure round the bellows increases, a pin 50 is moved up and the L-shaped lever 28 rocked about its axis 27 against the pull of the tension spring 60. After a little movement a projection 78 on the lever 28 engages the L-shaped lever 75 which has been resting against a stop, and rocks it about its axis 76 against the pull of the spring 83. The sideways projection 30 on the lever 28 eventually moves a snap action switch " off." The springs 60, 83 are adjustable by four screws at their ends, two of these screws being for factory adjustment. One of the other screws 66 determines the position of the R.H. end of the spring 60 and of a pin 62a fixed to a scale 70 which moves relatively to a fixed pointer and so indicates the pressure of the spring 60. The remaining screw 87 determines the position of the L.H. end of the spring 83 and of a pin 90 which co-operates with the - scale 70 to indicate the sum of pressure due to the two springs 60, 83.

Abstract: 688,400. Overhead conveyers. KING, Ltd., G.W. May 17, 1951. [June 1, 1950] No. 13740/50. Class 104 (ii). ln a conveyer system in which load carrying trolleys are pushed along a track by pusher dogs carried by a chain suspended from trolleys running on a track disposed above the load carrying track, the load carrying trolleys are transferred from a main to a branch track by an arm normally clear of both tracks in an inoperative position and of such a length as to bridge the centres of the main and branch line driving chains when means actuated on switching the load carrying trolleys from the branch line cause the arm to be coupled to a rotary member driving or driven by the branch line driving chain to impart angular movement to the arm and to move the arm from the inoperative position into engagement with a trolley and into the path of a branch line driving chain pusher dog the arrangement being such that on actuation of the arm the arm is engaged by a branch line pusher dog to propel a trolley from the main track into such a position on the branch line that the trolley will be directly  contacted and driven by the branch line pusher dog and the arm will be withdrawn and returned to the inoperative position. A trolley 11 propelled along a main track 10 by a pusher dog 12 suspended from a chain 13 mounted on rollers 14 running in a chain track above the track 10, is diverted on to a branch track 15 by a switch tongue 16 to a position where it is propelled by a pusher dog 19 suspended from a roller mounted chain 18. The trolley 11 on being diverted from the main track 10 to the branch track 15 lifts a lever 29 to raise a movable portion 25 of a circular runway 23 and to pivot an arm 21 upwardly about pins 22 so that a friction pad 27, mounted on a lever 26 counterbalanced at 28, engages the underside of a chain wheel 17. The chain wheel 17 rotated by the chain now rotates the arm 21 until it engages the trolley 11 by which time the trolley 1 is moved out of engagement with the main track pusher dog 12. When the arm 21 abuts the trolley 11 the friction between pad 27 and wheel 17 is not sufficient to drive the arm 21 and the chain 18 continues to rotate the wheel 17 until a dog 19 engages the arm 21 to propel the trolley 11 along the track 15. The arm 21 as it is angularly rotated gradually recedes from its position between the trolley 11 and the dog 19 so that the drive is eventually taken up by the dog 19. The trolley 11 on being moved out of engagement with the lever 29 drops the rail portion 25 so that the arm 21 on reaching its initial position drops to disengage the pad 27 from the wheel 17 and to move to a position where it will not engage a pusher dog 19. Specification 657,265 is referred to.
