Filed: 1935-10-04
Abstract: 463,659. Type-printing telegraphy. CREED & CO., Ltd., and SALMON, R. D. Oct. 4, 1935, No. 27461. [Class 40 (iii)] In a signal-regenerative system of the T-lever type for setting selector members in accordance with the state of a receiving- magnet during a short fraction of a signal period, a single T-member 27 is used for setting a series of selector members 34 in succession. When the armature 1 of the receiving-magnet moves, it disengages the detent 36 from the fixed stop 11. The lever 9, pivoted at 12, consequently descends and so turns the threearmed lever 16 about a pivot 15, releasing the cam shaft 21 which executes one revolution occupying 6¢ signal periods. The lever 16 and its pivot can be adjusted for the purpose of setting the instant of release. During the revolution of shaft 21, lever 9 is first raised by the action of cam 22 and then held up by bracket 11 which supports the foot of member 36 so that armature 1 shall not be obstructed by member 36. Lever 30 is then raised and lowered by cam 23 so as to permit lever 3 to be shifted bv armature 1 at selected instants and thereafter to hold this lever in position. The T-piece 27, pivoted at 37, is periodically lowered under the control of cam 24 and, by engagement with arm 5 or 6, is tilted to one side or the other and then held by jockey spring 29 and stirrup 38. Thereafter it is raised so as to engage the depending members 32, 33 and thus to set the frame 34.

Abstract: 646,670. Turning-gear. C. A. V., Ltd. Oct. 25, 1948, No. 27659. '[Class 7(v)] [Also in Group XXXVII] In electric starters of the kind in which a pinion d is slidable by an electromagnet into engagement with a gear wheel on the engine to be started and in which a switch, which may be comprised of contacts h, m, operable by the electromagnet is closed for supplying current to the starter after the pinion d has moved into engagement with the engine there is provided spring means i for imparting closing movement to the switch, the spring means being adapted to be energized by movement of the movable part, such as core a, of the electromagnet. When the electromagnet winding b is energized a hollow iron armature g, which is freely mounted on the plunger f of core a is magnetically held in contact with the end of the winding enclosure e by the flux generated by the winding b. During the first part of the movement of plunger f, a collar k secured thereto, advances into contact with an abutment j slidable relatively to plunger f and armature g. Continued movement of the plunger f causes the collar k to move abutment j into contact with the end face of a hollow part p, secured to the armature g, against the action of the spring i located between the other end of part p and the abutment j. After the pinion d has meshed with the engine the spring i causes the armature g to be separated from the enclosure e and contact h on the armature g to complete a circuit through fixed contacts m to turn the starter. During the return of the core a a spring n returns the armature and contact h to their initial positions. In a modification, the moving contact is operated through a toggle mechanism and an over-centre spring, the core plunger serving to compress the spring.
