Abstract: 753,690. Ratchet gearing. DECCA RECORD CO., Ltd. Jan. 17, 1955 [March 23, 1954], No. 8522/54. Class 80(3) [Also in Group XXXV] A shaft 14, Fig. 2, is rotated step-by-step in one or other direction by one or other of two solenoids 22, 23 associated with oppositely-acting ratchet wheels on the shaft 14, escapement mechanism 42 being provided to prevent overrunning and backrunning. Each solenoid actuates a respective claw 20, 21 to engage a tooth on one wheel and pull it through one step, and simultaneously the solenoid rocks a spring- loaded escapement member 42 associated with the other ratchet wheel so as to disengage, at the beginning of a stroke, a pawl 46 which normally prevents rotation and to engage, at the end of a stroke, a latch 47 which prevents overrun. Backrunning on the return stroke of a claw riding over one ratchet wheel is prevented by that pawl 46 which acts on the same wheel. Each claw 20, 21 comprises a spring strip, the end of which is bent to point towards the shaft. 14. The bent-back portions are guided between two rotatable or sleeved pins parallel to the shaft 14 and in radial alignment therewith so that the claws are held clear of the ratchet wheels until a solenoid is energized. Each escapement member 42 comprises a centrallypivoted arcuate member carrying a roller engaged by a pin on the solenoid armature. Attached to the arcuate member is a spring strip whose opposite ends form the pawl 46 and latch 47. The armature 34, Fig. 3, of each solenoid is urged outwardly by a spring 36 and is guided by an oilimpregnated sintered bronze bush 37 and collar 38. A brass washer is provided between the armature 34 and embracing core piece 33 and on the last part of the inward stroke an air gap is opened to facilitate the spring return.

Title: Improvements in linear-dimension gauges
IPC: G01B13/10
Filed: 1943-06-09
Abstract: 592,845. Linear - dimension gauges. MOORE, C. B. June 9, 1943, No. 9287. Convention date, May 14, 1942. [Classes 106 (ii) and 106 (iv)] [Also in Group XXIX] In a linear-dimension gauge in which a valve is controlled by the work-engaging member to transmit a fluid pressure dependant upon the dimension gauged, the valve co-operates with a valve seat provided in a wall of a chamber from which the said fluid pressure is being transmitted, the wall having a follow-up action with respect to the valve. Compressed air is supplied through a pipe 30, Fig. 1, to the gauging head 12 arranged, in the construction described, to measure the bore of a tube 10. A pressure related to the dimension measured is transmitted back from the head 12 through a pipe 43 to an indicator 44 and recorder 40, the chart of the latter being driven by air supplied from the main source by a pipe 33. The head 12 has two supporting rollers 16 and a gauging roller 17 and is joined by a flexible connection 22 to a rigid tube 18 marked to show the distance to which the head has been inserted into the bore. The gauging roller 17 is carried on a pivoted lever 46, Fig. 2, the movements of the lever being transmitted by a rod 49 to a valve 80. The compressed air supply is led to an inlet 71 communicating with the interior of two bellows 55, 56, the air passing through a port 77 to the left-hand face 78a of the valve 80 and thence to a space 72. This space 72 communicates with the atmosphere through the right-hand face 79a of the valve and through apertures 73 and a tube 67 with the space 62 outside the bellows 55. Movement of the valve 80 to the left causes a reduction of pressure in the spaces 72, 62, the bellows 55 then moving to the left, the tube 67 carrying the seats co-operating with the valve faces 78a, 79a until a balancing pressure is built up in the spaces 62, 72. This pressure, which is dependent upon the position of the gauging roller 17, is transmitted to'the pipe 43 by an outlet 63. Recording-apparatus. The pipe 43 is connected to a box 110, Fig. 5, containing a bellows 111 actuating a recording arm 115. The record disc 91 is mounted on a spindle 90. Compressed air from the main supply enters a box 96 through a pipe 38 to compress a bellows 93 against a spring 97. When the pressure is released by opening a valve 42, Fig. 1, the spring 97 extends the bellows 93 and, through ratchet mechanism 103, 105, moves the record disc 91 one step, the valve then being closed and the bellows 93 compressed in readiness for the next step.
