Title: Improvements in telephone systems
IPC: H04Q3/00
Filed: 1924-08-29
Abstract: 223,877. Western Electric Co., Ltd., (Assignees of Dustin, G. E.). Oct. 24, 1923, [Convention date]. Automatic exchange systems.-A digit-absorbing selector, for use in a multi-exchange system in which some of the exchanges have not reached their ultimate capacity, responds to the first digit it receives, absorbs the next digit without effecting any selective operation, and then hunts automatically for an idle trunk. The absorption of the second digit may take place either on particular levels only or may be irrespective of the level selected by the first.digit. In the 100,000- line system indicated in Fig. 1, comprising ten exchanges reached over different levels of a first or office selector 12, the selector 12 may be one in which the second digit is absorbed only on levels leading to exchanges (for example, that containing the subscriber 7) in which the unnecessary thousands-selecting stage has been omitted. Alternatively, the selector 12 is of standard type, and the incoming selector 13 in the incompletely-developed exchange is of the type in which the second digit it receives is absorbed on all levels. First arrangement, Fig. 3, in which the second digit is absorbed only on particular levels, for example, the third. Upon the seizure of the selector, relays 300, 310 operate and the first series of impulses is repeated to the vertical magnet 341 in parallel with a slow-release relay 320. At the end of the digit, the relapse of relay 320 completes a circuit 312, 326, 321, 394, for relay 330 which locks up over contacts 392, 343, 337, 380, but if the switch has been raised to the third level no circuit is yet completed for the rotary magnet 342. The next series of impulses is therefore repeated by relay 300 to relay 320 in parallel with a slow-operating relay 350 which locks up, but the operation of relay 330 prevents any further vertical movement and the digit is therefore ineffective. At the end of this digit, the relapse of relay 320 completes a circuit 326, 321, 394, 357, 335 for the rotary magnet 342 which, on operating, unlocks relay 330. If the first trunk is busy, relay 330 re-energizes over contacts 392, 343, 361 and the grounded test wiper 329, and the switch takes another step. When an idle trunk is found, relay 370 energizes in series with relay 330 to extend the connection. If the first digit dialled is other than 3, the operation of relay 330 at the end of the digit completes a circuit for the rotary magnet 342 over an extra wiper 345 and a righthand winding of relay 350, and hunting takes place at once so that the second digit will pass to a succeeding switch. Second arrangement in which the second digit is absorbed on all levels. In this case, the wiper 345 and the right-hand winding of relay 350 are omitted, and the operation on all levels is similar to that described in the preceding paragraph for the third level.

Title: Improvements in machines for winding electric coils
IPC: H01F41/06
Filed: 1922-07-27
Abstract: 206,203. Pattison, E. W., (Dictograph Products Corporation). July 27, 1922. Winding-machines; stop-motions; creel arrangements.-A machine for winding electric coils comprises a winding-spindle 4 and a driving- spindle 7 provided with coupling-plates 8, 9. The spindle 7 is driven by a pulley 14 against which a spring 12 presses to maintain the shafts 4, 7 in coupled relation. A clutch 16 is provided on the end of the spindle 4 and comprises a plate having an aligning edge against which is mounted the magnet pole-piece to be wound. A forked thread-guide 4 is reciprocated by eccentric cam mechanism to guide the wire, which is unwound from one of two spools 44, 45, on to the pole-piece. The spools 44, 45 are carried on a rod 41 and are provided with brake devices 47, 48. A guard 55 is provided; and the slack in the space between the spools 44, 45 and the pole-piece is such as to prevent breakage due to unequal winding. A horizontal shaft 58. Figs. 3, 4, 6, is driven by a worm 60 from another worm 61 fixed upon a vertical shaft 27, driven from the winding-spindle 4 by worms 39, 29. A measuring cam member 62 is held against lateral movement on the shaft 56 by a screw 63 which extends into a groove 64 in the said shaft, and the member 62 is provided with radially extending recesses 65 closed by screws 66 and having plugs 67 spring-pressed therein by springs 68 so as to lock the member by friction on the shaft 56. The cam 62 is provided in its periphery with a trip-notch 69, Fig. 6, provided with a shoulder 70. A bell.crank 71 is pivoted at 72, and its horizontal arm is pressed by a spring 73 against the periphery of the member 62. When this arm enters the notch 69, the vertical arm of the lever moves the pulley 14 against the spring 12 and uncouples the shafts 47. A ring 76 is rotatably adjustable upon the face of the member 62, and is clamped thereon by screws 77. The ring 76 is provided with a lug 78 which is adapted to engage with the end of a screw 79 adjustably fixed in the bearing block 57, thus serving to limit the rotation of the cam 62 in a setting direction when starting winding. The position of the cam 62 on the shaft 56 is set so as to wind the desired number of convolutions on the pole-piece before stoppage by the operation of the notch 69 and bell-crank 71.

Abstract: 466,994. Cutting tobacco. AMERICAN MACHINE & FOUNDRY CO. July 31, 1936, No. 21285. Convention date, Aug. 10, 1935. [Class 5 (i)] Dampened tobacco leaves spread upon a feed belt A are carried through a thrashing device B, where the side web portions of the butts of the stems are removed, to a butt separator C comprising sets of endless belts which progressively accelerate the stem butts to effect separation. The stem butts are then gripped between a pair of endless belts D which are twisted so that the leaves are turned so as to hang downwardly in which position they are carried between rotary beating members to disentangle the leaves and then through a suction mechanism by which the leaves are cleaned and spread out. Each projecting stem is then gripped between cam actuated gripper jaws G and carried through a drying chamber H in which the leaves are exposed to heated air ; afterwards the leaves pass sideways between two vertically arranged endless belts J provided with gripper bars that carry the leaves downwards to a shedding mechanism K, the gripped butts being cut off by a stationary knife I. The shredding mechanism comprises two groups of interengaging cutting discs 27 and the shredded tobacco falls on to a conveyer belt 28 that carries it to a winnowing device L which separates the heavy stem parts from the lighter leaf portions by a blast from a fan 30. A reciprocatory blade cutter co-operating with a ledger-blade may replace the rotary shredding cutters. The knife I may be dispensed with, the gripper jaws being opened by cams to release the leaves. Specification 419,595, [Group VI], is referred to.
