I Application filed April l5, 1902. Serial No. 103,065. (No model.)

T all whom, it may concern:

Be it known that I, GEORGE A. LONG, a citi-` quirements imposed for the use of the instru-v ment; and the object of my'invention is to pro- I vide a device of this class in which such signal may be conveyed to the central oice and in case the desired connection cannot be had that the coin or token deposited for such use .l may be returned to the user, these objects beingperformed without the use of eXtra wiring or any alteration of the instruments regularly used for conveying messages.

One form of device in which my invent-ion may be embodied is illustrated in the accompanying drawings, in which- Figure l is a front view of a set of telephone instruments embodying my improvements i with parts broken away to show construction.

My invention herein illustrated and described is designed especially for use in connectionwithatelephone pay or toll station adapted for use in connection with what is known as 6;,

a common battery or centralenergy system of telephone service. In such a set of instrumentsat the subscribers station there is the usual call-bell, transmitter, and a telephone or receiver, the latter hanging on -a switch-hook in the usual manner. A feature of this system is that the battery is located at some central station and the local battery of the old Aform of telephone apparatus is done away with in this new system. I

In the within drawings my invention is shown as applied in connection with the signal and switch' box, and my improved apparatus is preferably mounted above the switchboX. In calling the central oflice under this new system the lifting of the telephone or receiver from the switch-hook permits the latter to rise, which operation conveys a signal to the central oflice that the instrument is wanted for use. In embodying my invention for this form of apparatus I lock the switchhook normally and provide means for unlocking it by the performance of some act imvposed for the use of the instrument, as the insertion of a coin or token into the mechanism. The coin drops into the instrument to a position Where it is arrested in a runway. A trip device is then operated which will unlock the switch-hook lever and leave the .coin in a position of rest while the instrument is being used or until it is determined whether the Fig. 9 is a'detail diagram 5o i proper connection can be had. If the instrument is used, as soon *as the receiver is replaced on the switch-hook the latter'is moved, and its movement releases the coin and causes it to be discharged into a money-receptacle. If it is found, however, that the desired connection cannot be had, the operator at the central office causes the call-bell to sound and the movement of the armature of the magnet is utilized to discharge the coin from the runway into a position out of the case where it is accessibleand can be removed by the person who deposited it.

In case the telephone instrument, with the switch-hook normally locked, is located in the oiiice of a subscriber to whom a call is senty the latter may insert a coin in the coin-slot, push down the plunger, locking the switchhook, and remove the receiver, which allows the switch-hook to lift and releases the mechanism. After the call has been answered the central oflce causes the coin to be returned to the subscriber in the manner above described. On hanging up the receiver the apparatus is again locked for use as a toll-station.

In the accompanying drawings the numeral 1 denotes a signal and switch box, 2 the callbells, 3 the switch-hook, 4 the switch-hook lever, 5 the receiver, and 6 the transmitter, of a set of telephone instruments. These parts are all of a well-known type and especially known in connection with the common-battery or central-energy system of telephone instruments above described.

A case 7 is mounted on top of the signal and switch box 1, and this case incloses myv improved mechanism for controlling the movements of the switch-hook lever or arm 4, the

case being closed by a door which is secured.

by a lock,the case forming the coin-receptacle. A base 8 is secured in any suitable manner within the case,preferably so that the latter may be removed without disturbing the base. A support 9 is mounted on the base, and to this sup- ,portachannel-plate lOis secured. This channel-plate contains a runway 11, adapted to receive a coin of suitable size inserted through the opening or slot in the top of the case 7. A plunger 12 is mounted in rear of the coin-plate, with its upper end projecting through the wall of the case 7. This plunger is held at the upper limit of its play,.as by means of a plungerspring 13 thrusting against a projection 16 from the back of the channel plate. The lower end of the plunger is secured to a projection l5 from a follower 14. This follower is located on the opposite side of the channelplate from the plunger 12, the projection 15 extending through a slot in the channel-plate. A trip-lever 17 is located on the back of the channel-plate, being pivoted thereto Yat its lower end, a trip-lever spring 18 holding said lever in a normal position. This trip-lever bears Vastud 19, extending through a slot 2O in the wall of the channel-plate, this stud being located in the runway 11. The trip-lever also bears a trip 21, located at the back of the channel-plate l0.

A lock 22 is pivoted on the base 8 in the form shown toan extension from the under side of the base. This lock has an arm 23, arranged preferably' above the base 8 and underlying the end of the trip 21, a spring 24 being employed to hold the lock in its normal position. The lower end of the lock is adapted in its normal position to overlie the switchhook lever 4, a shoulder preferably being formed on the lock, against which the lever presses, the upper end of the lock being arranged to engage a catch 26, adapted to hold the lock out of position overlying the switchhook lever 4. A spring 27 is employed to hold the catch in its normal position. The lower end 25 of this catch is formed with a camsurface, so that as the switch -hook rises the catch is forced backward by contact of the switch-hook lever with this cam-surface.

A retaining-holder 28 is arranged to hold the coin in its position of rest in the coinchannel, but to be withdrawn when the coin is to be retained in the money-receptacle. This holder in the form shown consists of a rod secured to the lock-arm 23 and controlled in its movements by said lockarm. This holder extends upward in rear of the channelplate and projects forward through a slot or opening 29 in the rearwall of the channelplate.

A delivery-holder 30 is pivotally mounted on the base and projects upward and forward through an opening Vor slot 31 in the rear wall of the channel-plate. The upper portion or end of this delivery-holder is pivoted to the main or body part. The working end of this delivery-holder has a shoulder 46, which is adapted to be engaged by a trigger 47 located on the trip-lever 17. A counterpoise 48 tends v to hold this delivery-holder with its end normally located inthe runway in the'channel-plate. The lower end of the delivery-holder 30 lies in front of an arm 32, with which it is adapted to be engaged, this arm 32 being secured to `the armature 33 of the electromagnet 34 of the telephone apparatus. This delivery-holder is adapted to be withdrawn from the coin-slot when a coin is to be delivered to the user of the instrument.

A check 49 is secured to the switch-hook lever 4 and is adapted to prevent the deliveryholder from being withdrawn from the runway in any movement of the armature except when the switch-hook is at the lower limit of its play.

A casing 40 is secured to the back of the channel-plate, and in this casing is located a release 41. This release projects through an opening in the back ofthe channel-plate, and a spring 42 normally holds. it in a position with its end located in the runway 11. This release is provided with a release-pin 43 and IOO IIO

a withdrawing pin 44 located, preferably, on diametrically opposite sides. A cam 45 on the lower end of the plunger 12 acts upon the withdrawing pin when the plunger is moved down to withdraw the pin from the runway; The release-pin 43 is so located as to rest against the trip-lever 17, so that as the latter is swung on its pivot it is disengaged from the release-pin and allows the release to be moved with its end located in the runway and under the impulse of the spring 42.

A counterpoise 37 is pivotally mounted on the case 40, and a guide-pin 51 is pivotally connected to this counterpoise, the opposite end of the guide-pin passing through the rear wall of the channel-plate to a position in the runway. One end of the release 41 is adapted to strike this counterpoise 37 and forces the guide-pin 5l into the channel when the release is withdrawn. Tt will be seen from this construction that when the end of the release is in the runway the guide is withdrawn, and vice versa.

Aguard 50 is secured to the switch-hook lever in position to protect the opening in the box through which the lever passes and to prevent manipulation of the mechanism from the outside and by means other than those intended.

The operation of the device is as follows: The parts of the mechanism being in the relative position shown in Figs. 2, 3, and 4, a coin is inserted in the coin-slot in the wall of the case 7 and falls downward. resting against the guide-pin 51 and between it and the follower 14. (See'dotted lines of coin in Fig. 4.) As the follower is pushed downward the coin is forced against the trip-lever stud 19, which is forced downward along the slot 20. This downward movement of the plunger and follower causes the trip-

lever

1,7, through the stud 19, to be swung on its pivots, carrying the trip 21 against the lock-arm 23, forcing said arm downward and the lock 22 backward. In this movement the catch 26 engages the arm 23, thus holding the'loek in a position out of the path of movement of the switch-hook lever 4. (See Fig. 6.) The retaining-holder 28 having advanced through the opening or slot 29 into the coin-channel is now in a position to arrest the coin when it shall be released from the guide-pin 51. This swinging movement of the trip-lever 'disengages the release-pin 43 from said lever and also the trigger 47 from the delivery-holder 30, the latter being thus projected into the runway in position to arrest a coin therein. holder 30 isl pivoted in order that it shall work freely into and through the opening 31 after the trigger 47 in its downward movement has been disengaged from the shoulder 46 of the delivery-holder. The withdrawal of the trip-lever from the pin 43 does not effect the release 41, for the reason that the camsurface on the lower end of the plunger en- The working' end of the deliverygaging the withdrawing pin 44 holds the release at the backward limit of its play and allows it to move into the runway as the plunger moves Vupward and the cam-surface 45 moves along the pin. This movement of the release 41 into the runway permits withdrawal of the guide-pin 5l and allows the coin to move downward, resting upon the release 41 and the retaining-holder 28. The receiver being now taken from the switch-hook the switch-hook lever moves Aupward against the cam-surface on the lower end 25 of the catch,'carrying said catch back and freeing the catch-hook from engagement with the lock. The lock is prevented from moving forward by reason of the switch-hook lever being interposed in front of it, this movement of the lever, in fact, throwing the lower end of the lock .back a triiie and advancing the retaining-holder al slight distance farther into the coin-channel. The apparatus may now be used for the purpose of conversation. As the receiver is replaced on the switch-hook the lever is drawn downward, releasing the lock and catch, which are returned to their normal position by means of the relative springs. This movement withdraws the retaining-holder from the coinchannel and a coin falls into the case 7 or coinreceiver. When the parts have been operated to present the coin to the release and delivery holders in its position of rest, as above described, the receiver having been removed from its hook, if the central office shall find that the desired connection cannot be ohtained the user is so notified. By now again pushing the plunger downward the release 41 is withdrawn from the runwayrby the operation of the cam-surface 45 against the withdrawing pin 44, and the coin falls to a position resting against the delivery-holder 30. The receiver now being placed on the switchhook the check 49 prevents any movement of the delivery-holder 30 until the switch-hook has reached the lower limit of its play, at which point the check has passed below the lower end of the delivery-holder. The central oiiice now operates the call-bell in the IOO IIO

usual manner, energizing the magnet 34,

which vibrates the armature 33. This vibration of the armature carries with it the arm 32, swinging the lower end of the deliveryholder 30 and withdrawing its upper end from the coin slot. This movement allows the coin to travel along the coin-channel into a 'clip 36 outside of the case 7, from which position it may be removed by the user.

The term telephone toll apparatus has been used in connection with the description ofthe apparatus herein, in which a coin is used to operate the device to indicate to the central oflice that the requirements imposed for the use of the instrument have heen complied with; but it is understood that this term telephone toll apparatus as used in the specification and in the claims shall apply to IIS my apparatus, in which some act must be performed by the user before the required signal may be observed at the central station, whether the requirement be the depositing of a coin or token or the operation of a register, as .by a key, or any other act.
