Title: Improvements in or relating to motor control devices for telegraphic apparatus
IPC: H04L12/12
Filed: 1931-06-11
Abstract: 380,126. Actuation of switches. CREED & CO., Ltd., SALMON, R. D., and KIRK, 'S. E., Telegraph House, Croydon. June 11, 1931, No. 16983. [Class 38 (v).] Relates to switches of the kind described in Specification 284,740, [Class 38 (v), Electric switches &c.], for disconnecting a printer motor when signalling has ceased for a predetermined period, and restarting it when signalling begins again. According to the invention the switch is forced open by the inertia of a moving mass, a snap-action spring is provided, the interval elapsing before operation of the switch is made uniform, and the switch sends a clearing-signal to line. The disc 1 is rotated slowly counterclockwise by the printer motor 9 and when current flows in the line L the arm 2 is drawn axially towards the disc so that pin 3 engages in one of the holes 4. The arm thereafter rotates counterclockwise unless a spacing signal detaches it from the wheel, when it falls back to its original position. If, however, no signals occur before the arm reaches its topmost position, switch S is operated to stop the motor 9. The axial movement of arm 2 in response to signals is preferably' effected by cam action as described in the prior Specification. The arm 2 as it rises moves a spring-controlled guard 20 to the right about pivot 21, and when the arm falls in response to a signal this guard moves so as to cover the holes 4 and to prevent premature re-engagement. The number of the holes 4 is great enough to ensure uniformity of the time interval determined by the device. When a signal is received after a period of rest, the arm 2 falls and the momentum of the weight 17 ensures operation of the switch S. A horizontally moving spring-urged mass may be substituted for the mass 17. The arm 12 operates through a spring 16 which produces a snap action. A short interruption of the line L is effected by the switch S as the mass 17 reaches its topmost position. Arm 13 first breaks the line at 28, but when the threearmed lever 11, 12, 13 has moved a little further the blade 30 snaps upwards (owing to the action of spring 16) and closes the line again at 29.

Constructionwise the apparatus comprises props 9, 11 and a jack 13 for actuating a cantilever extension which are connected via valves 24, 25, 26 respectively to a pilot pressure line 27 for simultaneous movement whereby the said valves are connected to an exhaust line 16. Six control lines 17, 18, 19, 21, 22, 23 extend between each pair of adjacent valve extensions and the main pressure line is indicated at 15; the valves being adapted to be connected to the line 15 in response to the pressure in a pilot line 28. The valve assembly is provided with a filter 29 and each valve 24, 25, 26 has a high-pressure relief valve such as 31 connected to the exhaust line 16. The doubleacting advancing jack 6 is connected by conduits 34, 35 respectively to valves 36, 37 which are spring-loaded to connect conduits 34, 35 to exhaust. Pilot lines 38, 39 are provided to respectively connect the valves 36, 37 to the main 15. When the jack 6 is retracted it operates a switch 41, 42 to interconnect conduits 34, 43 and thereby operate a changeover valve 44 and interconnect conduits 38, 28. Two-way valves 45, 46, 47 operated by push-buttons 48, 49, 51 are also incorporated in the circuit as shown being re-set manually or by pilot pressure in a pipe 52 in series with a shuttle valve 53 having conduit connections 17, 21 responsive to supply pressure signals from the adjacent left and right hand supports when set against the roof. The pressure-setting signal is transmitted via a spring- loaded valve 54 to a relay valve 57 to connect a pilot pressure line 23 to the conduits 17, 21. Conveyor advance is effected when button 51 is depressed to operate valve 47 and supply pressure-fluid via conduit 61, valve 59, pipe 39 and valve 37 to the jack 6. Conveyor advancing pressure is maintained in the jack 6 when the button 51 is released to connect the pipe 61 to exhaust by virtue of the non- return valve 59 retaining pressure in the pipe 39. The 'modus operandi' by a miner operating the supports in sequence the Specification should be referred to.
