Patent GB-103952-A (GB)
Title: Improvements in or relating to Automatic Selecting Devices for Telephone Systems.
IPC: H01H67/06
Filed: 1916-08-11
Abstract: 103,952. Siemens & Halske Akt.-Ges. Aug. 11, 1916. Addition to 23336/13. Selectors. - Relates to selectors of the kind described in the parent Specification which are controlled by an escapement oscillated by the driving-force of the selector itself, so that to bring the selector to rest, it is only necessary for the test magnet to hold the escapement in a position to which it has been moved mechanically. According to the present invention, means are provided for restoring the driving power expended during a setting movement of the selector to a sufficient extent to provide for the largest setting movement. In the form shown, the wipers 2 of the selector are mounted on a shaft 1 which is rigid with a spring barrel 6 and a toothed wheel 5 co-operating with an escapement S under the control of the test and call relays P, R as described in the parent Specification. The outer end of the driving-spring 9 is secured to the barrel 6, and the inner end to a sleeve 11 rigid with a ratchetwheel 12, which is engaged by a detent 14 and by a spring pawl 13 connected to the core of a selfinterrupting solenoid 26 used for rewinding the spring. Mounted loosely between the barrel 6 and the ratchet-wheel 12 is a disk 15 having a lug 16 adapted to engage a projection 7 on the barrel 6. Also mounted loosely on the sleeve 11 is a coupling-member 18, 19 adapted to be engaged by a pin 17 on the disk 15 and by a pin 32 on the ratchet-wheel 12. A recess 21 in the disk 15 normally receives the end of a spring 22 in such a way that, when the disk rotates, the spring 22 closes a contact 25 in the circuit of the solenoid 26. The operation of the selector is as follows. The setting of the selector under the control of the relays P, R takes place as described in the parent Specification, the barrel 6 and wheel 5 rotating in the direction of the arrow, while the disk 15 and ratchet-wheel 12 remain stationary. After the selector has been used a number of times, the extension 7 on the barrel engages on the other side of the lug 16 on the disk 15 and moves the disk in the direction of the arrow. The spring 22 closes the contact 25 in the circuit of the solenoid 26, which continues to interrupt its own circuit at contact 25, and to step round the ratchet-wheel 12 to rewind the spring. The pin 32 on the ratchet-wheel engages the coupling- member 19 and moves this on to engage the pin 17 on the disk 15. The movement of the ratchetwheel 12 and disk 15 is then continued until the disk reaches its normal position, opening the circuit of the solenoid. The wheel 5 can'rotate more rapidly than the ratchet-wheel 12, and it may, in certain positions, rotate the disk 15 so rapidly that its pin 17 may reach the arm 19 of the coupling-member and actuate it. In these circumstances, premature opening of the contact 25 is prevented by the segmental part 20 on the arm 19, the part 20 serving to keep the contact 25 closed when the recess 21 in the disk 15 would otherwise allow the contact 25 to open.

Title: Improved apparatus for the production of pneumatic tyres
IPC: B29D30/14
Filed: 1949-04-30
Abstract: 663,312. Pneumatic tyres. DUNLOP RUBBER CO., Ltd., and STARFIELD, L. R. March 1, 1950 [April 30, 1949], No. 11571/49. Class 144 (i). Apparatus for applying tread stock 21 to a tyre carcase 24 which is supported on a driven drum 2 and a parallel relatively movable idling drum 15, comprises means 1. 4, 6 for driving simultaneously both the driven drum 2 and means 5 for feeding the tread stock to the driven drum, a tread-applying roller 25 pressing on and driven by the driven drum 2, a radially outwardly displaceable cam roller 20 bearing on the driven drum and arranged to actuate electrically-operated means 10 for connecting both a cam-shaft 8 carrying a tread feeding cam 11, and a cutter shaft 13a carrying a tread stock cutting means, to the driven drum driving means, and electrically operated means 7 actuated by the tread feeding earn 11 to stop the tread feeding means 5. As shown, the apparatus is started via a switch 28 which actuates an electrically-operated clutch 3 to connect a motor 1 to a shaft 4 driving the drum 2, the tread stock feeding means in the form of a pair of rollers 5 being driven from the shaft 4 via a chain drive 6 and an electrically-operated clutch 7. The tread stock 21 is fed by the rollers 5 down a guide channel 22 on to a conveyer belt 23 which rims over the treadapplying roller 25 at one end and a pulley 27 at the other, the roller 25 being carried on arm pivoted about the pulley 27. When the leading end of the tread stock applied to the carcase 24 displaces the cam roller 20, an electricallyoperated clutch 10 is actuated to transmit drive from the shaft 4 to the cam-shaft 8 and to a rotatable electrically-heated knife 13, the latter having a peripheral speed slower than the feed rate of the tread stock and being timed so as to sever, with a bevelled cut, the exact required length of tread stock. This timing of the knife 13 is adjusted by movement of the cam roller 20 circumferentially of the drum 2. After the cutting operation the tread feeding cam 11 on the cam-shaft 8 actuates the clutch 7 to stop the feed rollers 5, the drum 2 continuing to rotate so that the bevelled joint of the tread stock 21 is rolled down on the carcase 24 by the roller 25. At this point a cam 12 on the camshaft 8 closes electrical circuits to disengage the main driving clutch 3 (via tripping of switch 28) and also to operate, via a solenoid 19, a changeover valve 17 which controls a double-acting piston and cylinder 16, 16a to move the idling drum 15 towards the drum 2. The movement of the drum 15 is imparted to the tread applying roller 25 and cam roller 20, by means of linkages (not shown) to facilitate the replacement of the completed tyre 24. To prevent stretching of the tread stock 21, during its application to a tyre carcase, it may be backed with polyvinyl chloride sheet material.
