Patented Sept. 2, ices;

To all whom it may concern:

Be it known that I, FREDERICK W. Gem, of Newton, county of Middlesex, State of Massachusetts, have inventedan Improvement in Signal-Boxes, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing-like parts.

This invention relates to signal boxes especially adapted for use in police signal systems.

The object of the invention is to simplify the construction of a boxhaving a multiple signal transmitter adapted to transmit the calls which are ordinarily required for use in a police signal system, as for instance, the wagon call, report call and telephone call; and to equip the box with a telephone; and to so construct and arrange the parts that the wagon call may be transmitted by a key inserted from the outside of the box; and the report call may be transmitted by an actuatinglever accessible when the box door is open, and the telephone call may be transmitted by said actuating lever when the box door is open and the telephone is removed from its support. The several calls are properly distin 'uished, as for instance, the wagon call an the telephone call each consist of a boxnumber accompanied by a long dash, which serves as the differentiating impulse; and which is employed for operating certain de vices at the central station by which an alarm number in the telephone call; and the report call consists of the box-number only.

The invention also has for its object to provide means, operated by the signaling train, for including the telephone in circuit when transmitting the report call and also the telephone call and for subsequently excluding it; also to provide means for arresting the sig naling train While the telephone is included in circuit and for subsequently releasing it, permitting it to resume its operation and to exclude the telephone before or as it ceases to operate; also to provide means controlled by the closing of the box door for controlling the resumption of operation of the signaling train. The telephone is included in circuit when transmitting the report call in order that it may respond to a signal transmitted from the central station, in a well known manner, which causes the receiver to'producc ahumming sound. such signal being employed for the purpose of notifying the ofiicer to communicate with the central station by telephone, or for any other purpose. n

Figure. 1 shows in front elevation, a signal box embodying this invention. 2 is a similar View of the signal box, showing the box door open. Fig. 3 is a rear elevation of the multiple signal transmitter removed the box, together with a portion of the inner door of the box upon which it is supported, the parts being in their normal position. of rest, as for instance when the box door is closed. Fig. 4 is a similar view of the multiple signal transmitter, the signal wheel and back plate being removed. Fig. 5 is a n) left hand side levation of the transmitter shown in Fig. 3, the suppo1-tin -plate and outer door being shown in section, said door bein closed. Fig. 6 is a vertical sectional detail of the transmitter, with the parts in the position they will occppy when the box door is open. Fig. 7 is a detail of the signal-wheel and circuit operating devices adapted to be operated by it, and circuit controlling devices adapted tobe operated byaplungercontrolia go by the box door, "he parts being at rest, b in the position they will occupy when the bu. door is open, as for instance, when transmit ting the report call or telephone call. is a similar detailshewin of having turned suilicientiy to trai mi report call and the telephone as ha been included in the circuit. 9 is asinu ar de tail showing the signal wheel as having been turned suil'iciently to transmit the telephone 99 call, and the telephone still included. in the circuit. Fig. 10 is a detail showing theintermediary locking device tent/he signaling? train. 11 is an edge view of the Wheel. Fig. 112 is a modified form of signal 9 Wheel which may be employed, Figs. 13, i l and 15 are circuit diagrams oi the cox, parts thereof being in di ."erent positions for the transmission of the (liii'erent calls.

represents the shell the box, or case, 1 which is of any suitable size and shape, and a is the inner door, which lT-S as a sup porting plate for the operati is the outer door. On. the bad inner door a, the multiple signal tr; is supported.

1) represents the actuating lever of the transn'iitter, which is located at the trout the inner door, so as to be accessible when the-teeter door is open, and said. lever is eswhich is adapted to engage a spring pressed pawl. (see dotted lines Fig. 4) pivotally-connected to one side or face of a gear wheel b which is-mounted to revolve on said shaft 6 and to be turned by the spring actuated winding arm in a manner quite common in signal transmitters. The gear wheel 6 engages a pinion b secured to a shaft 5 to which is secured a gear wheel b which engages a pinion I) see dotted lines Fig. 4, secured to a shaft b, to which the escape-wheel b? is secured, which is engaged by a suitablepallet 11" secured to a pivot-shaft I).

A signalwheel c is secured to the shaft 5, and the mechanism. of the train is arranged to turn said shaft one complete revolution each time the winding arm is operated by the actuating lever, so that the signal wheel will make one round. The signal wheel 0 is made Wide enough to comprehend two signal portions, see Figs. 11. and 12, arranged. side by side, and adapted to be engaged by two pens c, c, likewise arranged side by side, see Figs. 5 and 6, and said pens are attached to a block 0 of insulating material, and when lifted will respectively enga e contact pens c, 0 also attached to said block 0", to thereby close the circuit. The signal portions of the signal wheel 0 are each arranged to transmit the box number and also a differentiating impulse, which latter in the present instance, consists of a long dash; one of the signal portions having the dash ar ranged to precede the box number, and the other having the dash arranged to follow the box number. The si nal. wheel c also has n o i 0 pro ecting laterally from it two pins 0" and adapted to SUUUUSSlVGlY engage a )en 0 also attached to said block e, and to lift said pen into engagement with the contact pen c attached to the block to close the circuit; or in lieu of said. pins 0 and 0 a single segmental portion may be provided, as shown at 0 Fig. 12. The three pens c, c and c are connected together and to a binding post d, to which one of the circuit Wires, as 2, is connected, but the three contact pens c, 0" and c, which they respectively engage, are separated, and being attached to the block 0 of insulating material, are thereby insulated from each other and one of said contact pens, as c, is connected by a metallic 's'trip d with a binding post d*, to which one of the circuit wires, as 3, is connected; and the other-two contact pens are alternately connected through a plunger switch mechanism by means of which either will be included in circuit to the exclusion of the other.

To simplify illustrating the circuits in the diagrams (Figs. 13, 14 and 15), the circuit wire 2 leads to the signal wheel. To each signal wheel contact pen a and 0", a switch contactpen is connected, represented at e and c, which are arranged side by side above the contact pens c 0", to which they are resectively connected. The outer ends of sai pens 0,6, occupy different planes, one above the. other, and a switch member 0 consisting of a suitably shaped plate, is attached to the block 0 in a plane above the contact pens e, 0, having its outer end bent to form a hook, c, which extends beneath the contact pen 6, and having a lateral extension e, which extends over the contact pen 6. forth causes it to engage one or the other contact pen 6 or e, to thereby connect one or the other contact pen 0 or c to the circuit which remains normally open.

The switch member e is connected with a binding post (1", to which one of the circuit wires, as 4, is connected. The switch member c? also has alateral extension a which extends upward in a diagonal direction and which is adapted to be engaged by a collar 6', preferably insulated, which is secured tothe inner end of a plunger rod a. rod 6 is made long enough to extend outward. through a hole 6 in the inner door so as to be struck by a boss 6 located on the inside of the box door, when the latter is closed.

The plunger 1 A spring (a encircles said plunger rod, which serves to thrust it outward, when thedoor is opened and the spring thereby permitted to act. When the box door is closed, the plunger rod will be pushed inward, and the collar 6 engaging the upward extension on the plate a will depress said plate and cause the switch contacts 6', e, to close, connecting contact pen 0 with the circuit, and when the box door is opened, the plunger rod will be moved outward by the spring e, and the plate c permitted to rise and cause the switch contacts a, e to close, connectingv contact pen 0 with the circuit.

The winding arm I) is extended and ar ranged to strike against the plunger rod e in Figs. 4' and 5, and when the plunger rod occupies its outermost position, as shown in Fig. 6, the box door being open, will be brought into position to be struck by the winding arm, to thereby arrest the signaling seaoee train before it has completed its round, for

i purposes to be explained, but when the plunger rod is subsequently pressed inward, said conical portion will be removed from beneath the winding arm and the signaling train thereb permitted to resume its move ment until the winding arm strikes the plunger red at a point in front of said conical portion and thereby stops the train at the completion of the round. A locking-device is also provided for the train, which is adapted to arrest'i-t at an intermediate part of its operation, and as herein shown, said locking-device consists of a pivoted detent f, see Figs. 4 and 10, arranged to engage a projection f on one of the wheels of the train, as for instance, on the gear wheel I)".

The detentf is free to turn on its pivot and to be moved into and out of position to engage said projection It is adapted to be moved into locking position, that is to say into position to engage said projection by gravity, when permitted to act, and for the purpose of moving it out of such positionor into its unlocking position, a sliding bar f is loosely or pivotally connected at its upper end to it, the lower end of which extendsdownward, below the signaling train, see Fig. 3, far enough to be struck by a short arm f secured to a pivot-shaft f, to which the telephone hook f "i is secured. When the, telephone is supported on the hook, the arm) f will be depressed and disengaged from the; lower end of the sliding bar f, but when removed therefrom said arm f will be lifted by means of a spring f, which is attached to it, sufficiently to engage the lower end of the sliding bar and lift said bar high enough to remove the detent f from the path of movement of the projection f, thereby moving it into its unlocking position.

While the telephone remains on the hook, the detent f will occupy a position to en age the projection f and arrest the train berore the round has been completed. Hence the locking-device thus provided is herein referred to as an intermediary locking-device. The detent f has an extension f, which is made long enough to extend beneath the plunger-rod e and said detent is so located with respect to said plunger rod that the extension will engage the conical portion e or will engage the plunger rod back of" said portion, according to the position of the plunger red, as for instance, when the box door is closed and the plunger rodpressed inward, as shown-in Fig. 5, said extension. will rest against the conical portion, see

dotted lines Fig. 10, and when in such posi tion the detent f will be held above and out of the path of movement of the projectionf, that is to say, will be'held in its unlocking position, so that if the box is pulled at such time, as it can be by means of an outside key, the signaling train will be operated and will not be'arrested by said detent, but will make its complete round, the winding arm finally returning to its normal position in engagement with the plunger rod. But if the box door is open and the plunger rod thereby thrust outward, as shown in Fig. 6, the conical pdrti on thereof will be moved out of the path of engagement of the extension f and the detentf, will be permitted to fall by gravity or otherwise, into the path of movement of the projection f, see full lines Fig. 10, and if the box is pulled at such time, as it may be by the actuating lever b, the signaling train will be operated but will be arrested during its progress by this intermediary locking-device, and when the box door is subsequently closed and the plunger rod pressed inward, the conical portion will return to its normal position and in so doing will engage the extension f and thereby lift the detent free from the projection and permit the train to resume and com ete its operation. Again, if the box door is open and the plunger rod thrust outward, carrying the conical portion forward beyond the extension so that the detent falls into the path of movement of the projection f, and

the box is pulled by the actuating lever b,

closed and the plunger rod pressed inward,

said conical portion will be moved far enough to disengage the winding arm, and the train thereby permitted to again resume its opera tion, and continue until the" winding arm engages the plunger-rod in front of said conical portion or runs down.

The circuit wire .4 leading into the box is connected to the binding post (1 and it has a branch wire 3 leading from it, which includes the telephone and is connected to the bind ing post (l and the circuit wire 2 leading into the box is connected to the binding post (1. The pin 0 is so disposed on the signal wheel that when the train is arrested by the detent f, it will have engaged the pen 0 and lifted it into engagement with, the pen 0 to close the circuit including the telephone; also the pin ('7 is so disposed on the signal wheel that when the train is arrested by the winding arm engaging the conical portion on the plunger rod, itwill have engaged the pen 0 and lifted it into engagement with the pen c", to likewise close the circuit including the telephone.

The operation of the box is as follows:-

permitted to resume its opera-Q lar flange g round said pintle.

as turned, the end of the flange will be en- :VVhen the box door is closed,

hole in the box'door, said key having a socket which fits upon a pintle formed upon the end of the )ivot shaft 1) 'and havin a wad which enters a recess formed in a circu- As the key .gaged and the pivot shaft bearing the actuatmg lever b will be turned and the winding arm I) operated to wind the signaling train. The plunger rod being at such time pressed ainward by the box door, theintermediary locking-devicef is held by the conical portion e" in its unlocking position or out of the path of engagement withj", and said conical portion at such time occupies aposition remote from the winding arm I)", so that it will :not arrest the winding, arm at an interme- :diate position on its return hence the signal ing train once started will continue to run wand complete its operation, the signal wheel imaking a complete revolution. The plunger rod being pressed inward, the insulated eol lar'e thereon en a es the extension 0" on the .S\Vlt(' l1 member, as shown in lugs. 33 and 5,

hand the-c1rcu1t contacts a, e, are closed and the circuit closer c c is thcreb ell'ective and the long dash followed by the box number will be transmitted.

At the completion of the round, the winding arm I) strikes the plunger rod in front of the portion c" and thereby stops the train. During the trans .-mission of this signal, the pens 0 and c are also engaged and lifted by the signal wheel,

.but the circuit closer a 0", is not effective .for the reason. that the contacts 0, c, are.

open, and the cirmritcloser a", a, while tem- .porarilyeffective performs no useful function, as the telephone transmitter and re- .ceiver are made of sulliciently high resistance so that the small amount of current that can pass through them at such times will not affect the receiving relay or other receiving ap )aratus in the circuit at central.

i vhcn the box door is open, the report call and the telephone call. may be transmitted. Referring first to the transmission of the re- 'port'call, the box door is opened and the plnngerrod moves outward until the conical portionc" thereof bears against the side of the winding arm I), being thereb arrested. The actuating lever is then operated and the winding arm operated by it to wind the. signaling train. As the x'inding arm is moved to wind the actuating spring of the train, it movesout of engagement with the side of the conical portion e"','th'ereb v permitting the plunger rod to continue and complete itsoutward movement. The outward movement of the plunger rod is sullicient for the conical portion e to disengage the extensionf of the intermediary locking-dwice, thereby permitting the detent f to fall into the path of 'ward movement of the movement of the projection f". The outplunger rod is also sullicient for the collar c thereon to move out of engagement with the extension 0 on the switch member, permitting the contacts e, 0 to close see Figs. 7, 8 and 9 and include the circuit closer a c and open the switch contacts (2 and 0, so that contacts a, 0', car not then operate the circuit to cause the (is before the box number. The signal wheel then revolves until the projection f engages the detent f, then stops, and during such movement the box number only is-transmitted. At the moment the signal Wheel is thus arrested, the pin c thereon engages the pen c, see Figs. 8 and 14, and moves it against the contact 0, thereby closing the circuit including the telephone. The telephone having thus been included in the circuit is ready to respond to a signal from the central station, which. may be transmitted in any well known manner, causing the, telephone receiver to produce a humming sound. Such a signal on the receiver may be employed to notify the ollicer to use thettelephone at once, or it may be employed for any other purpose. if no signal is received on the telephone rec *iver as soon as the report call has been transmitted, the door is closed. (losing the door thrusts the plunger rod inward, the collar c" thereon again moving into engagement with the extension [2 on the switch member, opening the switch contacts 1%, c to thereby disconnect lhe circuit so that the dash cannot be sent alter the boX number, and the conical portion e also engages the ixtensionf on the detent and lifts said detent free from the projection f, andthe signaling t-rain thcn again starts and runs until it completes its operation, the winding arm engaging the plunger rod and thereby stopping the train at the end of the round, the train being run completely down. The report call thus transmitted comprises only the box number, but it will be observed that the telephone is included in tho'cireuit temporarily, in order that there may be an opportunitv before the door is shut to receive orders or a call from the central station Referring now to the transmission of the telephone call, the box door is opened, the plunger rod moves outward as belore until the conical portion 0 strikes thewinding' arm I)", being thereby arrested. The actuat ing lever is then operated. and the winding arm operated by it to wind the signaling train. As the winding arm moved to wind the actuating spring of the train, it moves out of engagement with the side of theron' ical portion 1 thereby permitting the plunger rod to cont inue and complete its outward movement. 'lhe out 'ard movement of the plunger rod is sullicient to disengage the extensionf" of the intermediary locking device, thereby permitting the detentf to fall into the path of progress of the projectionf, and is also suilicient for the collar thereon to move out of engagement with the extension a on the switch member, permitting the contacts 6, 6 to close, and include the circuit close-r c a lhen the telephone receiver is removed from the hook preparatory to using it, and the arm f which is connected with said hook rises an d engages the sliding bar f and moves the intermediary locking device out of the ath of movement of the projection f. .1 1e signal wheel revolves and the box number is lirst transmitted, then the circuit closer 0 c, is temporarily operated by the pin 0, but without operating the receiving relays at central on account of the high resistance of the telephone receiver and transmitter, then the dash is transmitted, then the circuit closer c, c, is again operated by the pin 0 see Figs. 9 and 15, and just at this timethe winding arm 6 has returned so as to engage the conical portion 6 of the plunger rod to thereby arrest the train. The telephone call comprising the box number followed by a dash is thus transmitted, and the train arrested while the telephone is included in the circuit by the circuit closer a a". The officer after using the telephone, replaces it on the hook and closes the door. Closing the door thrusts inward the plunger rod, causing the conical portion e to disengage the winding arm b thereby releasing said winding arm, permitting the train to again start and run until the Winding arm engages the plunger rod in front of said conical portion, and during this subsequent or final operation of the train the telephone contacts 0 c", are opened as soon as the pin 0 disengages the pen 0.

In the transmission of the telephone call, the telephone may be removed from the'hook at any time but it the telephone is not removed from the hoolc at once the signal wheel. will be arrested by the intermediary locking-device and will then be subsequently released by the removal of the telephone from the hook, so that in any event, the full call will be transmitted and the parts come to rest with the telephone included in the circuit, ready for use. While the detent f serves as an intermediary locking device 1 or the signaling train, it will also be seen that the winding arm engaging the conical portion c of the plunger rod also arrests the si nalin train aim to the com )letion of its e r: l

round. ihe intermediary locking device is provided particularly for the purpose of temporarily arresting the train to prevent the dash for telephone call being sent unless do sired,.and to produce the three necessary distinctive police calls by the simplest and most natural acts oi a person desiring to use a box and without the necessity of using selecting devices such as a pointer; it also provides f or temporarily including the telephone in circuit for the purpose of receiving signals from pletely disconnecting the telephone, not only as a protection against injury from heavy currents over the circuit, but also to insure a private telephone service, so that no third party can listen to conversation over the circuit unless he has identified his location by first pulling his box, which will thereupon send its-number before it makes the telephone connection.
