Application filed December 12, 1907. Serial No. 406,178.

To all whom "it may concern:

Be it known that I, IRA F. MANNY, residing in Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvcmen ts in Selective Signaling Devices, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to selective signaling devices for use with tcle hone or other systems and has for its 0 ject to provide a mechanism to be placed in the same electrical circuit at the several stations and caused to be set in operation from the cen tral or signaling station, it being within the power of the operator at the signaling station to effect the signaling at whichever station is desired without signaling the other stations.

In order to accomplish the above results the invention comprises a motor detained by a magnet controlled pawl, which when released by the first signal from the signaling station starts the mechanism in operation, the subsequent signals from the signaling station serving to permit a step by step es- ,capement of a rotary member which has p of the station, where it is adapted to be engaged b r the pawl when the proper number of signa s has been given and when the pawl is moved out of engagement with the rotary member by mechanism controlled by the oporation of the motor, whereby the signaling member is detained by the pawl when the latter releases the rotary member, said rotary member being quickly moved by its yielding connection with the motor to take up its lost motion caused by its detention by the pawl, there being an electrical contact on the rotary member adapted to be brought into contact with the signaling member at such time to complete an electrical signaling circuit. A cam action caused by the r lative movement of the rotary member with the signaling member causes the latter to move out of engagement with the pawl at or after the time said signaling member makes the ringing contact for causing the signal, signal member is restored to its normal position with relation to the rotary member by spring action and the rotary member proceeds to complete its cycle of movement, the pawl being returned by the operation of the motor to its position for detainin the motor again. at the starting position. 0 the parts. On the signaling station sending a greater number of signals than the number of the station, the signaling at that station is avoided by the signaling member thereof havin assed beyond the pawl before the pawl is released from the rotary member. However, to prevent the signaling at suci station 011 a number of signals less than t e number of the station, a guard is provided on the rotary member in the path. of the pawl when'the latter is released from the rotary member and in advance of the signaling member, the movement of said guard producing a movement of the signaling member out of aposition of engagement with the pawl so that it is released before it effects the signalin by engag ng the contact.

Incldenta to the above construction it is a further object of this invention to provide a speed governor for the motor with an automatic clutch depending for its operation on the position of the rotary member with relation to the motor shaft, whereby the governor is coupled with and retards the operation of the motor during the detention of the rotary member by the pawl, but is disconnected therefrom to permit the motor to binations of parts and all equivalents.

Referring to the accompanying drawings in which like characters of reference indicate the same parts in the several views; Figure 1 is a front elevation of a selective signaling device constructed in accordance with this invention, the local signaling circuit being shown in diagram and the parts being in their normal osition Fig. 2 is a similar view thereof with t he parts in the act of producing the signaling through the local circuit Fig. 3 is a similar view with the parts in position for releasing the signaling member from the pawl by means of the operation of the guard when a signal has been given of less number than the number of the station to which this instrument belongs, the cam drum for the pawl being sectioned; Fig. 4 is a side ele ation of said device; Fig. 5 is a sectional elevationof the rear of the rotary member with its associated parts, showing the gearing for the speed governor and the electrical connections for the signaling contact; Fig. 6 is a vertical so tional view through these parts showing tln construction of the speed governor clutch; Fig. 7 is a detail view of one of the clutch members thereof and its supporting spider; Fig. 8 is a sectional view through the ref :try member on the plane of line 88 of Fig. 5, showing the electrical connection for the signaling contact; Fig.9 is a detail view of the brush connection for the signalin contact; and, Fig. 10 is a sectional elevation of the cam drum and the pawl.

In these drawings, (referring to Fi 4,) 15 represents a frame construction whic desirabl consists of a pair of lates connected togetiier and held a suitab e distance a art b corner posts as with ordinary cloc wor construction, there being a motor contained within the frame and comprising a ratchetbcaring winding shaft 16. loosely carrying a large driving gear 17, with a motor spring 18 connected at its ends to the winding shaft and the driving gear respectively, and a train of gearing 19, 20,21, 22 and 23 increasing in s eed from the drivin siiaft 24 which exten s a considerable distance in front of the front plate of the frame 15 and has a motor arm or starting arm 25 fixed on its end.

A disk sha ed rotary member 26 is loosely mounted on t 1e motor shaft 24 and, as shown in Figs. 5 and 6, has a yielding connection therewith which consists of a coil s ring 27 housed within a recess in the rear 0 the retary member and connected at its ends with he rotary member and the motor shaft 24 respectively. By reason of the yielding connection formed by the coil spring 27 between the rotary member and the motor shaft said rotary member has a tendency to turn with the motor shaft but may be detained for some time without interfering with the progress of the motor shaft.

As shown in Figs. 1 and 4, the rotary mem ber 26 desirably takes the form of a pair of disks side by side, though being in fact a single integral structure, the front disk bein of sli htly less diameter than the other an each )eing provided with a series of escapement teeth extending part way alon its peripher the escapement teeth of the ront portion eing designated 28 and the escape- Inent teeth of the back portion being desi natcd 29. An escapement is formed wit these teeth of the rotary member by means of an anchor pawl 30, which is pivotally mounted by having a ring shaped portion 31 loosely iittin g upon a cam drum 32 on a shaft 33. The shaft 33 is driven to turn the cam drum and move the pawl laterally by a train of gearing 34, 35 and 36 from the motor shaft gear 17 to a motor seams 24. One 1c of the anchor pawl engages the teeth 28 of the rotary member while the other leg engages the teeth 29, and a spring 37 tends to maintain the former engagement, while an electro ma et 38, by attracting its armature 39 carrie by the pawl, serves to and is normally engaged by the anchor pawl 30, its position with relation to the rotary member bein fixed at such time at a distance in advance 0 the first tooth 28 by astop pin 40 on the rotary'member held in en agement with the locking arm 25 by the action of the s ring 27 between the rotary member and t e motor shaft. As long as the locking arm 25 is engaged by the paw 30 all parts Wlll remain at rest, but as soon as the ma net 38 is energized by the first signal from the signaling station, it being in the electrical circuit including the various stations, the locking arm 2.5.is released toset the motor in operation and continues in its movement in the direction of the arrow in Fi 1, whether the rotary member is permitte to follow it b the escapement due to the succeeding signa or not.

While the anchor pawl 30 is loosely mount ed on the cam drum 32 to be free to pivptally swing thereon and produce the escapement action for the rotary member, according to the number of signals sent, it is compelled to move laterally, after the locking arm25 has made ap roximately a half revolution, by means 0 the cam action of said drum, the sleeve 31 of the anchor pawl being provided with a pin 41 (see Figs. 2 and 10) ridin in a cam roove42 in the eriphery ofsaid rum. This ateral motion of the pawl causes it to move out of the ath of .the escapement teeth 28 so as to re ease the rotary member after an interval of time sufficient for giving the greatest number of signals, thus permitting the rotary member to quickly turn under the action of its sprin 27 to catch up with the locking arm 25. he pawl is soon returned by the return bend in the cam groove 42 into its normal position where it will engage the locking arm at the end of its single revolution and etc the mechanism in its normal position. Fhe gearing between the drum 32 and the motor shaft is such that they operate in unison, the drum making one revolution of each revolution of the motor shaft: The pawl is kept in its proper position against the tendency of its 5 ring 37 by means of a stop pin 4,3 on the rame with which it engages.

From the foregoing it will be understood 1B0 that each instrument in the signaling circuit I stop pin 48, so that the signaling at this sta is set in operation by the iirst signal from the signz'iling station and the rotary member thereof is advanced one tooth for each signal given, the awl detaining the rotary member when ti signals have ceased and until the motors have completed approximately a half of their cycle of o )eration, as determined by the position of the cams on the pawl drums, when the pawls are thrown out of engagement with the rotary members to permit them to uickly catch up to their loc ing arms 25 and continue therewith until the starting position is reached where the locking arms encounter the pawls which have just previously been returned to their engaging positions. In order to effect the signaling at the respective stations, the instrument of each station is rovided with a signaling member 44 whici comprises an arm on a ring or eccentric strap 45 which turns on an eccentric 46 carried by the rotary member. The eccentric is pivotally connected at 47 to the rotary member, but its swinging action is not involved in the ringing movement of the signalin member and for the purpose of considering t iis movement the eccentric may be treated as fixed on the rotary member. The signaling member 44 is positioned alongside of that tooth 28 which corresponds in number to the number of the station in which the instrument is used. being number four in the instrument shown in the drawings, and is in a osition' to be engaged by the pawl 30 when t e latter is 'moved from said tooth 28 by the cam drum as before explained. The signaling member 44is maintained in this normal position by being held against a stop in 48 on the rotary member by means 0 a coil spring 49 which connects an arm 50 on the ring 45 with the rotary member. When the signaling member 44 is engaged by the pawl 30 and the rotary member is released therefrom the signaling member is detained b r the pawl while the rotary member quick y turns to catch up with the locking arm 25 which has had a considerable lead owing to the length of time that the rotary member was detained by the pawl, before the latter was released therefrom. During the turning of the rotary member the eccentric 46 thereon moves in such a way as to gradually withdraw the signaling member 44 from the pawl 30, and the disengagement of the signaling member from the pawl is so timed that it does not take place until a signaling contact 51, which is mounted on and insulated from the rotary member, comes into engagement with a lug 52 on the back of the signaling member, as shown in Fig. 2, thus serving to complete an electrical circuit for causing the si aling at this station. As soon as the si a ing member 44 is released from the paw its spring 49 ouicklv restores it to its position against the tion is only momentary.

The signaling contact 51, as shown in Fig. 8, is connected by an insulated conducting pin 53 with a contact rin 54 on the back of the rotary member and aTso insulated therefrom, there being a binding post 55 connected to and insulated from one of the plates of the frame 15 and carrying a brush 56 bearing upon the contact ring to maintain connection therewith throughout the movements of the rotary member. The local signaling circuit 57, as shown in Fig. 1, preferably includes a bell 58 connected with a battery 59 and having one terminal connected with the binding post 55 and the other terminal grounded on the frame 15 in any desirable manner. The signaling circuit is completed only when the si naling contact 51 is in engagement with t 10 lug 52 on the si nalin member 44, the circuit then being esta lishe through the bindingpost 55, brush 56, contact ring 54, conducting pin 53, insulatin contact 51, the signaling member 44 engage therewith and the frame 15 through the line 57 including the bell 58.

lVhen the number of signals sent by the si naling station isgreater than the number of any particular instrument, the signaling member of that instrument has passed beyond the pawl so that when the pawl is given its lateral movement to release the rotary member it does not engage the signaling member to produce the signaling at that station. However, when the number of signals sent from the signaling station is less than the number of any particular instrument it is necessary to have a means which will prevent the signaling member of that instrument being held by the pawl a sufficient length of tlme to cause it to enga e the signahng contact. This means, in t e form of the invention illustrated in the drawings, comprises a guard 60 carried by the eccentric 46 and normally held against a stop pin 61 on the rotary member by the action of a spring 62 which positions it alongside of the tooth 28 which immediatel precedes the tooth beside which the signaling member 44 is stationed. The osition ofthe pivotal connection 47 for t e eccentric 46 is such that when the uard 60 is engaged by the pawl, which wili be true in every case where the number of signals sent is less than the number of the instrument, the movement of the guard 60 away from its stop pin 61 causes the eccentric 46 to swing on its pivotal connection 47 and carr both the guard 60 and the signaling mem er 44 out of, engagement with the pawl 30 before the signallng member engages the signaling contact 51, as shown in Fig. 3. The pawl 30 is of sufficient width to enable it to'stand in the path of both the guard 60 and the signaling member 44 as soon as it releases the rotary membar. The signaling member 44 has a sto pin 63 which 1s engaged by the guard at suc times so that the signaling member will move with the guard and the guard is of suflicient length to cause it to remain in engagement with the pawl as long as the sig na ing member 44 1s in engagement with the pawl, thus avoidin the possibility of having the guard release first and by its return movement extend the ringing member into further engagement with the pawl so as to detain it until the signaling contact reaches it. As soon as the guard and the signaling stops 61 and 48 and the connections of the eprmgs 62 and 49 with the rotary member. ith this end in view the rotary member is desirably provided with a series. of openings 64 arranged in an arc formation concentric. with the eccentric 46 when in its normal position, thus allowing the eccentric to keep its resent normal center inits various ad ustments, though ch l the'point of pivotal connection, and also eecting the change of position of the guard and the signaling memer so that they stand 0 posite the teeth 28 which correspond with t e number of the instrument, the signaling member being alongside of the tooth of the same number as the instrument and the guard being alongside of the tooth in advance. Inany such adjustment the guard and the si aling member will operate in exactl the same manner as above described for tile number four instrument as shown in the drawings.

It is desirable that the speed of the motor should be accelerated after the period of signaling has passed so asto restore the instrument to its normal startingposition without unnecessary loss of time, and with this object in view the motor is designed to o erate at the maximum speed desired except uring the signaling operation when a governor is automatically connected therewith to retard its speed, the governor being automatically disconnected as soon as the pawl is moved out of engagement with the teeth of the rotary member. The rotar member has a gear ring 65 set in an annu ar recess in the ack thereof, said gear ring being provided with internal and external teeth at its outer edge meshing with a pinion 66 and a car wheel 67 respectively which are mounte on a stationary supporting strip 68 conven- 'moves with the'motor sha t 24,

iently attached to the frame. The gear wheel 67 meshes with a pinion 69 on a governor shaft 7 (l which arries spring mounted governor weights 71 connected to a sliding friction disk 72 which is brought more or less forcibly into engagement with a friction arm 73. The friction arm 73 is pivotally mounted and is drawn by a spring 74 against the end of an adjusting screw 75 which determines the position of the friction arm and thereby the speed at which the motor may run when under control of the governor. A inion 76 is splined on the motor shaft 24 etween the gear 36 and the rotary member 26 and is pressed upon by a coil spring 77 so as to give it a tendency to move toward the rotary member and hold cam shaped teeth 7 8 on its side into engagement with similar teeth 79 on a spider which is secured to the rotary member. As long as the rotary member 26 is not retarded b the pawl and in other words, as long as the locking arm 25 is at or near its stop pin 40, the cam teeth 78 and 79 stand end to end as shown in Fig. 6 and the pinion 76 is held thereby out of mesh with pinion 66, but as soon as the pawl retards the rotary member, as it does during the signaling operation and until it is thrown out of engagement with the rotary member by means of its cam, themovement of the motor shaft relative -to the rotary member causes the cam teeth to pass each other and the spring 77 slides the pinion 76 along the motor shaft and into mesh with pinion 66 thus connecting the motor shaft with the governor mechanism and permitting the latter to retard the operationof the motor. This condition continues until the pawl is moved laterally b its cam and the rotary member is release to catch up with the motor shaft, when the cam teeth 78 and 79 bring their cam surfaces into engagement with each other and force the pinion 7 6 out of mesh with the pinion 66 and thus uncouple the governor from the motor shaft, permitting the motor to speedily complete its further operation until the parts are restored to their original condition.

The 0 eration of the invention has been describe in detail incident to the description of the arts, but it may be briefly reviewed as ollows: With the parts in the condition shown in Fig. 1, the first signal from central or the signaling station energizes magnet 38 and swings the pawl 30 to release the lockin arm 25 and start-the motor in operation, t e rotary member 26 being first checked by the engagement of the first tooth 29 with one arm of the pawl, and then being detained bythe engagement of the first tooth 28 with the other arm of the pawl as soon as the magnet is denergized by the breaking of the signaling1 circuit. Further signal pulsations repeat t e swinging movemerrt of the pawl, allowing the rotary momber to escape step by step in its endeavor to follow the motor shaft, a tendency-due to the coil spring connection 27 between them, said motor shaft being steadily moved forward by the motor under restraint of the governor which is coupled therewithduring the signaling. If the number of signals sent corresponds to the number of theinstrument, being four in the present case, the pawl remains in en agement with the tooth of the correspon ing numberuntil the motor has made a sufficient advance to cause the cam drum 32 to move the pawl out of engagement with the teeth of the rotary member and into engagement with the signaling member 4a standing alongside of said tooth. As soon as the rotary member is thus released it quickly turns under the action of the coil spring 27 until it catches up with the motor shaft, in the meantime bringing the signaling contact 51 into engagement with the contact lug 52 on the signaling member which is being de tained by the pawl 30, as shown in Fig. 2, the signalin at this station resultin from such contact icing no sooner effected t an the sig nalin g member 4 1 is drawn out of its engagement with the pawl 30, owing to the cam action of the eccentric 46 on which it is mounted. When released the si naling member 44 resumes its position on the rotary member under the action of its spring 49 and when said rotary member catches up with the motor shaft the cam teeth 78 and 79 effect the disengagement of the pinion 66 to disconnect the governor from the motor and permit the motor to speedily return the parts to their normal position where they are stopped by the reengagement of the lockingarm 25 with the awl 30. i

S ould the number of signals sent be greater than the number of the instrument,

the signaling member would have passed beyond the pawl 30 so that when the pawl is thrown out of en agemcnt with the rotary member the signa ing member moves along with the rotary member without being enga ed by the pawl and consequently the signa ing at this station is not reduced. When, however, the number of signals sent is less than the number of the instrument the guard 60 is first engaged by the v awl when the pawl releases the rotary memlier and by swinging the eccentric on its (pivotal connection 47 both. the guard an the si naling member are released from the pawl bcfbre the signaling contact 51 reaches the signaling member, as shown in Fig. 3, and consequently the signalirg at this station is not produced.

By means of this invention a number of telephone or other instruments may be connccted in the same circuit and the signaling may be produced at an y one desired without signalingany of the others, and thus multiple party lines may be established with the resu ting saving in cost of service and without the annoyance to the subscribers of having to hear the signals intended for other parties.
