Patent GB-892224-A (GB)
Title: Combined carriage-return and line-spacing mechanism
IPC: B41J11/24
Filed: 1958-12-15
Abstract: 892,224. Typewriters &c. OLYMPIA WERKE A.G. Dec. 15, 1958 [Feb. 27, 1958], No. 40322/58. Class 100(4) An electrically operated line spacing mechanism having a control switch, mechanically operated by the line spacing operation, included in.a clutch relay control circuit is described embodied in a typewriter or like machine having a mechanism which can effect line spacing with or without carriage return at any position of the carriage as described in Specification 886,229. The control switch opens the control relay of a magnetic clutch at the completion of line spacing without carriage return. The actuating mechanism for locking the carriage acts so that on depression of the line spacing without carriage return key Z contacts W2 Zl are changed over and a locking member 60 is inserted into an escapement wheel 14 at the same time closing contacts 320, 321; 324, 325 in series with a normally closed control switch 326. Movement of a rod 19 finally closes a switch 327 which operates the control relay to actuate a magnetic clutch 1 to cause a drawband 4 to effect line spacing. Operation of the relay releases a magnet 480 allowing a spring 290 to cause a detent 271 to engage a latch 260 to lock the locking member 60 in its locking position. On completion of the line spacing movement a lever 80 opens the control switch 326 which opens the relay circuit thus disconnecting the magnetic clutch 1. Opening of the control relay re-energizes the magnet 480 and if the key Z has been released the locking member 60 is returned to its initial position but if the key Z is still depressed the locking member 60 remains engaged with the contacts 320, 321, 324, 325 closed and as the drawband slackens the switch 326 again closes the relay circuit. The relay will then be operated again, a delay circuit being employed so that the line spacing mechanism can restore first and the renewed operation of the relay can cause repeated line spacing. A modified construction of the magnet 480 is described which includes a coupling which on release of the magnet operates a keyboard locking device. Other locking devices and the operation of the key W to effect carriage return with line spacing are similar to the arrangement described in Specification 886,229. Specification 862,397 also is referred to.

Initially the two halves of the primary winding are connected to produce fluxes # 1 , #<SP>1</SP> which are in opposition in the centre leg of the core thus no output voltage is induced in the secondary winding 102 although an output voltage is induced in the secondary winding 103 by the flux # 1  (see Fig. 12). When operation of the magnetron is required the halves 101, 101<SP>1</SP> of the primary winding are connected so as to produce fluxes # 1 , #<SP>1</SP> 1  which aid each other in the centre leg (see Fig. 11). Thus an output voltage is produced in the secondary winding 102, with the flux # 1  still producing an output in the winding 103. The fluxes # 2 , #<SP>1</SP> 2  caused by the load current in the winding 102 flow through the magnetic shunts 106. In the embodiment shown in Fig. 9 the magnetic core is in a cruciform shape with all the windings on the centre leg with the secondary winding 102 in two series connected halves, one on each side of the leg dividing the centre leg. If desired a further secondary winding may be placed on the centre leg and this winding may, if desired be an extension of the secondary winding 102.
