i CALL-REGISTERING MECHANISM.

Specification of Letters Patent. Patented June Y15, 1915.

Application lled December 14, 1912. Y Serial No. 736,878.

Mechanism, of whichthe following is a full,l

clear, concise, and exact description. This invention relates to telephone toll devices and more particularly to a device wherein toll is collected andregistration is made for each successful call.

The object of this invention is to provide .a call registeringmechanism in combination with acoinv collecting apparatus-.which is simple in construction and eiiicient and reliable in operation.l To accomplish this ob'- ject electromagnetically operated means un- 'Eder the control of the coin distributing mechanism are provided whereby onlysuccejssful calls orv those forwhich a .coin 1s `collected are recorded by a suitable register-v ing'1 device. A This invention will be lfully understood vfrom the following descriptiontakenvin connection with the accompanying drawing in hic/hs Y Y Figure 1 is a side elevation, partly in section, of a part of a coin collecting and registering device constructed in accordance wit this invention; Fig. 2 is a side elevation of the coin collecting device with the inclosing housing and outer wall of the coin chute removed; Figs. 3 and 4 are detail views of the coin distributing mechanism showing the location yof the various elements during the 'depositing and refunding operations; and Fig. 5 is the preferred system of "connections .shown dia'grammatically.

l A base plate 5 serves as the foundation for the coin distributing mechanism and registering device. Supported on the base plate 5 is a zig-zag coin chute 6 of the usual ccnstruction provided withl coin collecting and coin returnA channels. An electromagnetic system composed of coils 7 and 8 is provided with a tilting armature 9 Aon which are locatedtwofixed'pinsl() and 11 and a spring lpressed movable pin 12.` The pins carried by the armature project into the coin chute 6 above the divergence of the deposit and refund channels and provide means for arrest;

ing aY vcoin in itsdownward course ,for clos'- irlg a breakin the signal circuit and for directing the arrested coin` into either the deposit or refund channel. The armature prise `a movable coin distributor which is kept in a central or neutral position by means of levers 13 and springs 14C.

rrlhe registering mechanism or service meter lconsists of an actuating coil 15 con- Vtrollin a pivoted armature 16 to which is The pin 10 is insulated'from the armaturev and is connected to an insulated contact point 25 on the pivotal axis thereof by an insulated conducting ,strip 26; `Mounted upon the base or frame of the mechanism in any suitable manner but insulated therefrom and from each other are two contact springs 27 and 28. The contact spring 27 is provided-.with a contact point 29 adapted to be engaged by a pin 30 carried by armature 9 when the same is rotated in a counter clockwise direction, as shown. inFig, 4, and is Y connected to one terminal of the coil 15 of the service meter by a conductor 31. The contactspring 28 1s provided with. a contact vand the pins carried thereby, therefore', com

32 engaging the contact point 25 when the p armature is in a neutral position as shown in Fig. 5, but which is adapted to be removed the armature; and a contact 33 adapted to vbe engaged by the armature when the saine is tilted in a clockwisev direction, as shown in Fig. The spring 28 is Aconnecti-id one terminal of the-coil 7 of the 'coin collector magnet by means 'of aconductor 35i. Ene

' common terminal of coils 7 and 8 of the coin collector 'l distributing 'magnet` is connected to coil 15 by conductor 35, while the independent terminal of coil 8 is-joined to the' line wire .L by a conductor.

When the armature is tilted f is @aber dii rection the contact between points 25 and 32 from such engagement upon the tilting of4 u is broken on account-'of the spring 428 being raised slightly from its normal position 1b?- f.

contacting with the edge of 'the 'armature' as shown in Fig. 3 or the insulated buffer 37 as shown in F ig. Il. This contact is, however', lnot broken until the armature strikes the spring contact 28 or the pin 30 vengages the contact 29 depending upon the `direction of movement of the armature.

A source of energy l0 furnishes the energizing current for operating the system through a pairof keys atl and 42.

In service a coin placed in the upper part of the chut-e6 and released is arrested between pins 11 and 12 as shown in Fig. 2. The movable pin 12 contacts with the fixed pin 10 anda circuit is provided for the grounded source of energy 4l() as follows: Line L, conductor 36, coils@ and 7, conductor 34e, spring 28, contact points 32 and 25, conducting strip 26, pins 10 and 12 to ground. Consequently, when either key il or l2 is closed current will flow over the circuit just traced. 1f the call is successful key 41, for example, is operated sending positive current over the line to tilt the.

armature 9 in a counter-clockwise direction as shown in Fig. t. The coin is deposited breaking the contact' between pins l() and 12 and contact points -25 and 32. This breaking of the contacts, however, does not take place until the contact point 29 carried by spring 2'? has been engaged by pin 30 carried by the armature. A. circuit is, therefore, formed from grounded source of energy 40, line L, conductor 36, coil 8, con# ductor 35, coil 15 of the service meter, conductor 31, spring 27, Contact point 29, pin

30, armature 9 to ground. Current thus passes through the lservice meter coil which attracts its armature effecting the registration of the call. If, however, the call had been unsuccessful, current of the opposite polarity would have been sent over the line to tilt the armature in a, clockwise direction as shown in F ig. 3. rEhe. coin is released into the refund channel and the contact ben tween pins lOand 12 is broken as liereinbefore described. This contact, however, is not broken until contact point 33 of the spring 28 engages with the armature 9. Current then passes fromgrounded source of energy d0, key ft2, line L, conductor 36, coils 8 and 7, conductor 34, vspring 28, contact 33, armature 9 to ground. 1t will thusl be observed fthat when a coin is returned no current passes through coil 15 of the service. meter and no call is recorded.

The coil 15 of the service meter being connected in a branch circuit which is substituted for one `winding of polarized magnet when the coin distributor is operated to collect a coin, may therefore beoperated from the same source of current as is used to operate the coincollecting magnet and over a portion of the same circuit, thus greatly simplifying the Winding of the apparatus and avoiding` the use of a second source of energy for operating the register. Moreover, the actuating coil l5 will receive substantially the same amount of current as is passed through the windings 7 and 8 when the coin distributor is operated. This results in a more positive operation of the register 13 than would be obtained if the register was connected to operate from the coin distributer,since it is well known that a straight electromagnet will exert considerably greater pull upon its armature in response to a given energizing current than will be exerted upon a centrally pivoted armature of a polarized magnet in response to the same amount of energizing current.
