y As shown in` the drawings lthe mechanism lects which o f the contact fingers shall actuate the signals when the fingers are engaged by the contact arms, or one set of contact levers may be used to indicate one digit in a code number and another set of levers to indicate another digit in the code number. When any of one set of contact levers on a control board is closed circuit is made through the motor which rotates the shaft. A catch is provided for holding in closed position whatever contact levers have operated and so long as they are held in operative position the motor continues to run andthe code number is repeated. When it is desired to stop the apparatus an additional lever arm on the control board is operated to engage a clip in circuit with magnets on thel control boards and the magnets, through levers connected to their armatures, release the catches from the various lever arms and allow their springs to act to raise them. In order that this release operation 'may not occur when the signal is only partly given, and in order to prevent stopping the mechanism at any point other than the true initial point, an additional opening is provided in the magnet circuit which is bridged by a contact arm carried by the rotating shaft at one point in its rotation. This contactarm is arranged on ,the shaft so as to make contact only after all the signaling contactl arms on the shaft have made contact so that when the motor is started again the initial contact will always be made by the kfirst signal contact arm. l

The time and fire alarm signals are in the present instance given by continuously ringing all the bells at regular intervals. The ,inn terval for the time alarm being longer than the interval `for the fire alarm. Instead of a contact arm on the shaft which makes but a single contact in each rotation, there is, therefore, provided a wheel carrying a number ofteeth disposed at regular intervals on itsy circumference so that it may make a number of contacts with its fingers in a single rotation. 0f course, a wheel with a single tooth might be used in place of a Contact arm or a plurality of contact arms arranged at shortyangular intervals might be used in place'of. a wheel. The time and alarm signals might be operated from lever larms on the control boards as are the code signals, but it is lpreferred to provide separate and different means for their operation. A signal contact device suitably located to he operated either automatically, as by a clock or other mechanism, or manually is provided and this contact energizes an electromagnet which attracts its armature and shifts an arm, carrying a contact finger and a pair of spring contacts, into position to cause the spring contacts to be bridged by a stationary contact and to place the contact finger so that it may be engaged by the teeth of the wheel on the shaft. Circuit through the motor for operating the sha-ft is made at the bridged spring contacts and circuit through the signals is completed through the bridged contact and at the contact finger when it is engaged by a tooth on the wheel. l/Vhen the arm hasbeen shifted it is caught and held against an attracting spring by a catch. A star wheel associated with the catch carries a pin which engages and releases the catch 7 when the star wheel has completed a revolution. .This allows the arm to be retracted and the circuit broken. The star wheel itself is carried by the arm and as the arm is shifted into operative position the star wheel is brought into position to be engaged, at each revolution of the contact wheel, by a pin carried by the contact wheel so that when the said wheel has completed a suliicient number of revolutions to cause the star wheel to complete a single revolution the circuit is broken and the mechanism and signals brought to rest.

In the accompanying drawings Figure l shows a wiring diagram of a portion of the 9 mechanism particularly the rotating shaft and the parts mechanically associated therewith; Fig. 2 is a wiring diagram of a main control board; Fig. 3 is a wiring diagram of an auxiliary control board; Fig. 4 is a plan 9 view of the rotating shaft and the parts mechanically associated therewith; Fig. 5 is a section on the line 5 5 of Fig. 4, showing the arm shifted into operative position; Fig.

6 is a section on the linetof Fig. 4L, showl ing the arm in inoperated position; Fig. 7 is a plan view of a control board with the casing removed; Fig. 8 is a side elevation of a control board, the casing being shown in section and Figs. 9 and 10 are detail views 1 showing the catch mechanism for the contact levers on the control board.

Referring first to Figs. 4:, 5 and 6 there is al motor M which rotates a shaft S through' `worm gearing W. The shaft S is l of conducting material and carries contact arms or

wipers

37, 38, 39, at), All and 4t2. These contact arms are arranged in sets. One set consists of the

arms

37, 38, 39 and these arms are arranged at equal angular 1 distances' about the circumference of the shaft S. The

second set

40, 41 and 42 arey arranged yat equal angular intervals and the internal intervals in each set is preferably the same. Between the last arm 39 of the l first set and the first arm l0 of the second set is an angular interval greater than that between any two arms within a set. It will appear later that these arms cause the ringing of bells when they make contact and their arrangement is such as indicated above so that when contacts of the first set are used to cause the bells to ring a tens digit of a code number and those of the second set to ring a units digit, the code number may be 13o ing and on this may be placed over the various buttons 101 insignia to indicate the connections made by the levers operated by the respective button. A catch 88 for holding the levers depressed is made in two parts, one part consists of a` strap 107 which is held upright by a lateral arm 108 bearing against a leaf spring 109 mounted on the base of the board. The other portion consists or' a similar strap 110 held upright in similar manner by an arm 111 also resting upon the leai spring 109. The outer ends or' the lever arms L1, etc., are curved so that as the lever arms are depressed `into engagement with the clips they press back the straps 107 or 110 against the pressure of the spring as indicated by dotted lines in Fig.

.9 and when they have reached their depressed position the spring forces the strap back over the end of the levers to hold them down. The signal controlling levers are all of the same length so that after one has been depressed if another is depressed it will push back the strap and release the first lever. This is so as to the levers in any one set, that is between the levers L1, L2 and L3 or the levers L01, L02 and L03. The levers L1, L2 and L3 are used, when a two digitv code number is to be given, to indi,- cate the tens and the levers L01, L02 and L03 to indicate the units. It may, therefore, be necessary to hold two of the lever arms depressed at the same time and vin order to let them be depressed separatelybut held down together the catch is made in two parts, the strap 107 holds down either of the first three leversand the strap 110 holding down either of the last three levers. The lever arm LR engages the clip 13 which is in the circuit of'a release magnet'RM. This lever is curved at the end like the signal levers L1, etc., but is shorter than those levers so that it can be depressed and caught by the strap 107 without releasing the other levers. When so depressed it causes the circuit through the release magnet RM to be closed as soon as the bridge contact 53 on the shaft S bridges the

contacts

52 and 54. llVhen the magnetRM is energized it attracts its armature 112 which carries at its eXtreme end a hammer 113 which strikes the arm 108 extending from the strap 107 fieXing the spring 109 and pushes the strap 107 back releasing the contact levers L1, etc. Since the strap 110 is separate from the strap 107 the levers held by the strap 110 wouldvnot be released, but there is a lug 115 evtending from the end of the strap 107 into engagement with the strap 110 so that when the strap 107 is forced back to release the levers it also forces back the strap 110 and so all the levers are released. It will be observed, however, that the lug 115 does not interfere with the independent operation of the strap 110 to catch one of the levers L01,

L02 or L03 after one of the levers L1, L2

or L3 has been depressed.` Indicating lights TL, AL and XL are shown separated from eachother by darkening partitions 116 and each may be provided with a crown light 117 in the'top of the casing for the control board. Only one light may be used on an auxiliary control board while a main control board may have as many lights as there are control boards in the system.

The mechanical construction of the control board and contact mechanism has now been made clear. Attention is directed to Figs. 1, 2 and 3 which show the electrical connections between the various portions of the apparatus. At 0B are indicated diagrammatically bells which may be located at various places throughout the plant where it may be desired to have the signal heard. In the drawing are shown three bells in series and it is to be understood that each bell represents a separate signal station, it being necessary to have but one bell at each station. 0f course, the invention is vnot limited to the use of three bells since any number of signal stations may be served, there being one bell at each station and if desired the bells may be arranged in parallel or they may be arranged series-parallel in groups. The cable 0 connecting the various control boards to the contact mechanism is shown as broken away in the three figures, but it is to be understood that the cable is continuous between `the various mechanisms and that a wire bearing a reference numeral in Figs. 1 or 2 or 3 is a continuation or branch of the wire bearing the same numeral in another figure or iigures. For instance, the wire marked 21 in Fig. 1 is connected with 21 in Fig.` 2 and 21in Fig. 3. There is shown a main control board in Fig. 2 and an auX- iliary control board in Fig. k3 and there may be one or more oeither of these, each being a reproduction of these and the connections being the same. The variouslever arms of the control boards are indicated in Figs. 2

and 3 by dotted lines running from the supporting rods to the vclips and indicating the connections'which are made when the lever arms are closed. It is to be understood, of course, that the lever arms are not all closed at the same time. To cause a signal of a singlekdigit one of the arms L1, L2 or L3 will be used and to cause a signal of two digitsfthere will be used in addition one of the lever arms L01, L02 or L03. For purposes of illustration it may be assumed that the lever arm L3 has been closed.

37, 38, 39, 40,41 or 42 leaving their re-l spective' lingers 3l, 32, 33, 34, 35 and 3G an undesirable spark might be produced, but to 1t yvvill be :remembered thatthe contact iinger's 3l to 36 are connected through the controlboard E tothe Aside of the line bythe Wire, 2l and that vthesha'ft S carrying the contact arms 37 to 42 is connectedby the Wire26 ,through the ybellsfto Ythe Bl side ci? the line. One side of the condenser B0 is; therefore, connected to the Wire l21 by the Wire "46 and the othery side of the condenser vis connectedto the Wire l26 by the Wire 47.

Any spark -ivhich might otherwise -occur heis,j therefore',y avoided. y l y y It vvill be remembered that` the Wires from the auxiliary control board AE 4alsoiarenconn nectedy to the. cable Cy and, therefore,A the corresponding `Wires on Fig. vv3 are marked with thesarne reference numerals as on Fig.

2..y It Will thus be readilyjseen that `the saine signal y circuits Vmay be made by y, operating thecorresponding contact levers on lanr'au'xilf iary call board.- n f y v v l/Vheneither of the Contact levers L15 L2,

theindicating lamp lLthence through the ,Wire 87 and the cable@ to the point 55 and thence through Wire to the B side of the L? are closed a branch circuit is made from `the clips 192er 3 through fthe wlreBG and line. 'Another branch is also closed through' Wire 22 c'ahle C to yauxiliary controlv board AE through the lamp AIL .and Wire y87 and cablegC to point V55 and thence by Wire 56 vto the yB side of vthe line. Thuslanips ist operation an additional branch circuit is made from the levervarm through the catch bar 88 and the wire 89 `which passes through the *cablek C to the control board E and through the lamp lAL and by the wire 90,

to thev wire 87 which passes through the cable C tothe point 55 and thence through the wire 56 to the yB side of the line.y In Fig. 2 only one lamp AL has to show vbut obviously 'one may be added for each auxiliary control board in use and may be connected up with its respective board as is the lamp AL into the board AE.y l, 4

To stop the apparatus the release lever LR or ALR, etc., may be closed.` The circuit for the release magnets may be traced from one side of the line through the wire 20 and the wire 21 through the cable C to the rod R andthe lever arm LR, to the clip 13, which it engages, through the'wire 48 to the pointy 49 where the circuit'branches, one branch passing by the wire 50 through Athe release magnet'RM and the wire 51 through the cable C to the contact inger52 through the bridge contact 53, when the rotation of the shaft S has brought it in the proper po-V sit'ion, through the contact finger 54 to the point 55 and through the wire 56 tothe B side of the line. From the point 49 the other branch passes through the wire 57 and the cable C to the point 49a on the control board 'AE and by the wire 50 through the release magnet ARM and the wire 51 through the cable C where it joins the other branch passing through the

contact mechanisms

52, 53 and 54 to the B side of the line. All the release magnetson all the control boards are thus energized and all the leverk arms released when the bridge piece 53 is brought into contactwith the

fingers

52 and 54 by the rotation of the shaft S. A similar releasing circuit may be made by closing the lever ALR on an, auxiliary control board.

In order 'toavoid an undesirable spark passing between the lever arml LR and the clip 13.*when the lever arm is released there is provided a condenser RC connected across the opening. It will be remembered that the lever armLR is connected to the Aside of the line through the rod R and the wire 21 passing through the cable C, while the clip 13 is connected to the B side of the line through thewires 48, 50 and themagnet. One side o f the condenser RC is, therefore,

connected to the A side of the line by thel

wires

58, 5,9 and 60 and the other side of the condenser is connected through the wire 57 to the point 49 between the wires48 and "50.KA This prevents the spark which might otherwise pass between the clip 13 .and

the

contact lever LR.

, When the time contact 67 is closed a circuit is completed from the A side of the line through the

wires

5,8, 59 and 68 through the time contact 67 and the

wires

69 and 70 through the time magnets TM and the wire 71 to the B side of the line. This lifts the arm 92 and causes the bridge 65 to connect the spring contacts 63 and 64. When the arm is raised it is held elevated by the catch 94 until it is mechanically released'by the pin 98 after the shaft S has made the pretact 67 thus avoiding the spark which might otherwise form at the opening of the contact.

' The circuit through the motor when the time signal is in operation may be traced from the A side ofthe line through the

wires

58, 61 and 62 to the spring contacts 63 and 64 bridged by the raised bridgcpiece 65 rand through the wires 66 and 24 through the motor 'M and by the wire 25 to the B side of the line.

The signal circuit when the time contact is in operation maybe traced from the A side of the line through the wires, 58, 61 and 62 to the spring contact linger 7 4 which is engaged vby the projections ony the time wheel 75 as it rotates from which the circuit passes through the shaft S to the wire 26 to the signals CB and thence through the wires 27 and 25 to the B side of the line.

The circuit through the fire Contact 76 may be traced from the A side of the line through the

wires

58, 59, 60 and 77 through the lire contact 76 andthe wire 7 8 through the lire magnets FM and by the wires 79 and 71 to the `B side of the linc. This raises the arm 92 and causes the bridge 8O to connect the

spring contacts

81 and 82 in which. position it is held until it is mechanically tripped after the shaft S has made the predetermined number of revolutions. The motor circuit may then be traced from the A side of the line through the

wires

58, 61 and 83 through the

contacts

81, 80 and82 and through the wires 66 and 24 through the motor M and the wire 25 to the B side of the line. The signal circuit may be traced from the A sideof the line through the

wires

58, 61 and 83 through the contacts 81 and 8O to the contactfinger 84 which engages the fire alarm wheel 85 as the shaft S rotates from which the circuit -continues through the wire 26 and the signals CB through the wires 27 and 25 tothe B side of the line.

The koperation of the device `will ,be readily understood. One of the levers L1, L2 or L3 on onel of the control boards may be depressed and held down by the catch 88. 'llliis will close the circuit through the. motor lv'l which will immediately'begin torotate the shaft At the same :timethe indicati--l ing lights IL, on the various control boards` will be lighted and if 'an auxiliary control board isoperatedfits corresponding light All) on the main i controlxboard fwill be lighted,` Inconnection therewith one of the levers L01, L02, ,L03 maywormay not be depressed. The shaft S as itfrotatesswill bring the/contact arms to l2 carriediby it in contact with theirrespectiye contactfinn gers, thus completing one `or more `ofthe branch circuits through :the signals and causing signals at' the 'various stations in accordance with the selection made on the control board. This operation willi continue and the signal be repeated untilafter a lever RL on one of the 'control boards has been depressed and the bridging kpiece 53 has been brought, by the rotationl ofthe shaft, into contact `with its fingers 52, eli-When Lthe re-` lease magnets Will operate to `release the lever catches and open allthe circuits bring ing the motor and apparatus to `rest and eX;`

tinguishing the lights on the various control boards. Either of the extraordinary for emereenc signals ma `be brouehtfinto o 3- eration at any time by closure of the circuit through the corresponding magnetsTM `or FM and the motor started the `bridging contacts carried by the karmatures of the magnets. The rotationof theshaftby the motor will cause theteeth on the `Wnees to engage the contact fingersand close the sig-r nal circuits. This operation will continue until the circuit is openedby"themechanical trip when the star Wheel has been rotated.
