This. inventiomrelates to improvements in impuls'e' s endin'g' devices ofthe flkind-used in transmitting current impulses for theop-' 1 oration of selective 'circuit controlling. de-

vices which maybe located at ajcentral office .for the purpose of extending a connection through fromv one party to another or they.

The object ofithisinvention is to provide F21 a sender where the manipulations on the 'part of the operatorare" especially simple,

andconsist merely in the moving of a handle around a' number dial, from whatever position it might have, to. the number "wanted' followedby the depression ofa pro jection on thejhandle into'a' hole ad acent to the figure.

In this invention there provided a power storing mechanismwhich may be op- .30 erated by the. rotation of thehandle in either direction, and is adapted during the first few manipulations thereof to store 'up a suificientsupply of power to last during sev- Y eral successive manipulations',-thereby eli 'ni- M ating the necessity of operating this part of the meehanism; every time .a subscribers number is selected. Anau'toma-ticcontrolling. device is therefore provided forthe release of this part of the mechanism, from v controlbythe'o eraton of. the handle, when ever afull supp yof power has been stored.

Y 7 There is further provided a means for con-- trolling the numberof impulses to be sent by each selective manipulation, and a mechanis'm' associated therewith 'forlocking the i handle in operated position unt il such 1m "pulses have been sent This arrangement makes; 'it, .possible to select and. send the i i rapid succession without confusionand with the most economical use of power.

The several features of myinvention may be more readily understood by reference to the accompanying drawings in which- Fig fel .iS, a perspective'view with parts snssmr'io tsnivnna.

This mechanism consists of a shaft 11 running longitudinally through'the centerof the machine, which is adapted to operate a claw clutch consisting of two members 12,13, each of which has projections which fit into recesses of the other. The driving member 12 is slidably mounted and keyedto shaft 11, by means of the. longitudinal slots 14% therein being engagedby a pin 15 on the shaft, so that it may readily be disengaged from its mate,

the driven member 13, which is mounted loosely on the shaftll. This member 13 is attached to a disk 16 which forms the supportfortwo spring-pressed pawls 17, 18 located on opposite sides thereof. Located on the upper side of the disk 16-is the ratchet wheel 19 adaptedto be engaged and rotated by the pawl 17 when the disk. is. turned in a clockwise direction, and located ing the shaft 11, and its outer end attachedbymeans of a loop to a pin 23 on gear wheel 24. This spiral spring is adapted to .'be

wound in clockwise direction, and through the medium of the claw clutch and pawl and ratchet mechanism just described. This is done directly by the pawl 17 engaging ratchet-wheel 19 which is attached, by means of four posts 25, to thegear wheel 24, and the pawl 18 engaging the I indirectly b i ratchet whee .20, which is coupled by means of'atrain of gears to the gear wheel- 24.

' Said-train-of gears consists of gear wheels 26., 27, 28 "and 29, geari26 being attached to ratchet wheel 20, gear 27 beingmounted between a bracket 30. and the bottom plate 3 1, and gears 28- and 29 being fixed on shaft 32 which is mounted between a bracket 33 and bottom plate3l. This arrangement will give to the gear wheel 24 the same direction 7 of rotation regardless of which of the two ratchet, wheels 19 and 20 maybe actuated by the shaft 11. The direction of rotation of all these parts is marked by means of arrow -points in Fig. 1. It. may be mentioned here There is provided an automatic control- 1ing'device..for 'the claw clutch by means of which {continuous p y of power is maintained-in the spring during selecting operations} The driving member of said clutch, -.for that purpose, first, is caused to automatijcally-engage-with its mateand allowed to wind the spring until the proper amount of 35.

power has been stored up in the same, and,

second, is caused to beautomatically disen- -gaged until such a time as the stored up 4 I i are controlled by. a feed screw-34 slidably mounted on a carrier, hub 36 and having the "pins 37, passing through the longitudinal 'pow'er'in the spring has been exhausted,

These automatic actions of the driving clutch member take place alternately and slots38 cutin the hub and engaging a groove in the periphery of the driving clutch member 12. Bythis arrangement, this clutch member 12 is made to participate in the 1011- gitudinalmovement of the feed screw, but

I not in a rotary movement of the same that ,imay.v take place at intervals and the purpose of which will hereinafter. be made clear. The'carrier hub 36 as well as the feed screw 34 will participate in rotary movements of r the operating sleeve 22 on account of the hub beingjattached permanently to the sleeve 22 by means of two screws 39. A guide nut 40 I isadapted'to engage the thread on the feed I screw3 4' for the purpose of guidingand controlling the movement of said screw.

Said nut is held in a fixed angular relation Jto the ratchet wheel 19 and ear wheel 24 bymeans of two ears 41 on the same engaging two ofthe posts 25, but is allowed to slide longitudinally on these posts against the tens on of-either one of two sets of the. spring 21 will now be described.

m'anently fixed to the shaft 11. The other coiled springs 42, 43 located (as shown in Figs. and 7 respectively on opposite sides of the ears and surroundmg the posts 25.'

The operation of this controlling device will now be described with particular refer ence to Figs. 5 and 7. The condition of the parts, as shown in Fig. 5, indicates that the spring 21 has been wound; that is, the driving clutch member is assumed to have engaged the driven member and rotated the same in either direction through the medium of the shaft 11, which rotation has caused either the ratchet wheel 19 or to rotate the gear wheel 24 in a clockwisedirection, While doing so, the guide nut 40, which naturally must have participated in this rotation,'-had also, by engaging the thread on the feed screw 34, first, been forced downwardly thereby against the tension of the springs 42, and later, itself forced the feed screw and driving clutch member upwardly at a time when the tension of the springs 42 was strong enough to overcome the friction between the teeth in the claw -clutch. The guide. nut and feed screw 34 will now remain in this position, shown in Fig. 5,-until the power stored up in the spring 21 has been exhausted. Such a condition of the parts is shown in Fig. 7 that is,

- the power previously stored up in the spring has been used up in the sending of impulses, and the spring will now be wound the moment the shaft 11 is rotated, because the driving clutch member 13 is in engagement with its mate 12. The clutch member 12 .having been so placed by the following movements: the impulse sending machanism was driven by the rotation of the sleeve 22, which transmitted, through the medium of the carrier hub 36 and the pins 37, rotation to'the feed screw 34. The guide nut40, which during these operations'is not rotated, must first have been forced upwardly against the tension of the springs 43, by engagement with the thread on the feed screw, and later itself forced the feed screw and the driving clutch member downwardly at a time when the tension of springs 43 was sufiicient to overcome the friction-of the feed nut and pin 37 against the carrier hub 36. The guide nut and feed screw will now remain in this position (Fig. ,7) and hold the driving clutch member in engagement with its mate until the spring 21 is again suffieiently wound, when the parts will again assume the position shown in Fig. 5 ready for a suceeding operation.

The mechanism for the actual sending of the impulses that go to make up a subscribers number and which in its operation makes use of the power stored up in consists of the handle l0 having one end fastened to. the supporting crank 82 perend of the. has; is provided aim an operatingknob 83 and a latch pin 44 adapted,

when the handle. is pressedinto theposition shown in dotted'lines'in Fig. against the tension of the spring 45,130 enter one of the holes 46 in the top frame plate 47. 1 Close to each one of these holesis marked the number of impulses that aresent out over the line whenever the mechanism-is started by the latchpin 44: entering the corresponding hole. A latch plate 48 is mounted on'sleeve t '22 by means of. the -hub 87 and the connectingarm 88. This latch plate 48 is provided with a series. of apertures'78 of varying lengths, one for each hole in the top plate At .each one of these' apertures 1s mounted,.1n a slot on the plate/l8, a starting cam slide 49 having anoutsidecam sur-. face 50 of approximately the same length as Y the corresponding aperture,-a toothed segment coupler 51 and an inside camsurface 52. The outside cam surface50 is adapted ".to be engaged "by, the latch gin] {l4 when pressed down in the 'correspon ting aperture v [of thelatch 'plate48 and'the' slide, 49 moved thereby toward the center of the machine.

,The following is a brief summary of the operation of this invention. The winding engagement with each other, either when the handle isturned in a clockwise direction, 'by' 130' meariSf of the pawl 17 engaging the ratchet --mined by'the engagement of the arm 61' awithinterrupter 63 .on one hand, and the ;;pulses may take place is controlled and reguconsisting of the usual weighted springs 78 attached to a worm 7 9 which meshes-With of the spring 21 may take place whenever the two members of the claw-clutch are in wheel 19 which is connected to the gearwheel 24 by means of the posts 25, or when the'handle is turned in a counter-clockwise direction, by means ofthe pawl 18 engaging with the posts 25 and be forced gradually downward on the feed-screw 34 against the tension of the springs 42, and later itself force the feedscrew and driving clutch member 12 upwardly when the tension in the springs 42 is suflicient to do so. During the unwinding of the spring for operations of the sending mechanism, the feed'screw must rotate with the carrier hub 38 and sleeve 22 and forcethe nut 40 upwardly against the tension of the springs 43 and later the nut itself forces the feed-screw and driving clutch member downwardly when the tension in the springs 43 is sufiicientto do so. The shifting of clutch member 12 out of engagement with its mate takes place Whenever the spring 21 is fully wound, and the shifting of clutch member 12 in engagement with its mat-e takes place whenever the spring is run down, but such shifting actions depend principally on a certain amount of power that must first be stored up in either one of the series'of springs 42 or 43. v

When the handle is depressed for the purpose of sending a series of impulses, the

latch pin 44 enters a hole 46 and the-corresponding aperture 78 of the latch plate 48 and engages the outside camsurface 50 of the cam slide 49 and moves the same a short distance toward the center of the machine. The operating slide 53, which is forced to participate in this inward movement of the slide 49, is adapted to rock the starwheel 57, which in turn transmits its motion to the cranklever 59 and arm 61. T he arm 61 then releases the interrupter 63 which will start to revolve under tension of spring 21 and send impulses over the line by manipulation of the springs 64 and 65. Simultaneously with the release of the interrupter the coupler 51 locks with gear 7 6 which now is free to revolve, and the latch pin 4A is therefore locked in the aperture 78 by means of the edge 74 therein engaging the slot 75 in the pin. The interrupter 63 and latch plate 48 now keep on revolving until the locking edge 74 releases the latch pin 44: which will take place as soon as it has slipped by the slot ,75 on the pin. Immediately after the release of the latch pin 44 all the parts return to normal and the interrupter is stopped. The number of impulses sent by the interrupter depends therefore principally on the duration of the period during which the handle is locked in opera-ted position, and that is determined by the varying lengths of the edges 74. The mechanism now is ready for the selecting and sending of a second group of impulses representing a digit, and quite a number of such groups as a comparatively few movements of the handle in either direction will store up sufficient power in th spring for the sending of several groups of impulses.

It is obvious that many modifications could readily be made in this invention without departing from the spirit thereof.

The apparatus herein disclosed should therefore be taken merely as illustrative, and the invention limited merely by the scope of the ap )ended claims.
