Mounted upon the outside of the inclined portion B1 of the cover is a dialing assembly which in the form shown her is generally similar tothe dialing mechanisms used.in telephones. It is provided with a finger stop Gand rotatably mounted dial plate' C1 which has perforations C2'. Lying beneath the dial and fastened to the housing is a\ numbered disc 03. The numbers of the disc are so spaced and written that they are norm-allyin alignment with the openings C2 in the dial. C4 is a plate or washer'iastened to the dial plate C1 and provided with letters or other markings C5 which are in alignment with the openings C2.

Projecting upwardly preferably from the portion B2 of the' cover are two bosses D, D1 respectively.' Mounted 'for limited `mouvement within the boss D is a push button member D2. This memberis provided with a stem D3 of angular cross-section, as here shown, it is square, which stem projects through an opening' or perforation D'1 in the top of the housing. Within the boss D bearing at one end against the top B2 land at the otherv against the bottom of the push button D2 isa spring D5. Du is a pin or projection formed in the stem D8 and adapted to' prevent excessive upward movement of the push button and-stem. D8 is a lever pivotalmounted between lugs D" which extend 90 from the stem D3. The lever is preferably provided with a fiat portion D", which in po# sition shown in Figure 4 rests against the stem D3. The lever is normally held in that position by a spring D10. D11 is an insulatfastened at the bottom of the stem D1. Beneath the stem D3 and fastened to the inside of the casing is a'combination switch which is generally desi nated by the letter E. This switch is provi ed with short :sal

Within the housing, and fastened to the stem F1 is an enlargement F2. F1 is a spring lying within the boss D1 bearing at one end upon the portion B2 of the casing and at the other end upon the push button F. Lying beneath the push button are the spring leaves F5, F". F2, F2

- are insulating parts which serve to insulate the spring leaves F5, F5 from each other and from the housing. F5, F 9 are screws. by means of which the spring leaves'and the 1nsulating parts are removably mounted with! in the housing. F10 is a projection formed upon the spring` leaf, F5 and insulated from it.

G, G1 are bracket or supporting members mounted upon the base portion A of the housing. These bracket members are provided respectively with 'bosses G2, G3 and upwardly extending parts or lugs G5, G5 respectively. The'bosses G2, G8 are hollow and adapted to serve as bearings for the alignment .with

shaft G0. G2 is a sleeve removably mounted on the shaft G5 'an/d having preferably formed integrally with it a ratchet wheel G8 and a segment G2. The segment G1 1s provided with an enlarged arcuate portion G10 which may carry raised numbers G11 and other symbols G12. Thesenumbers and symbols correspond with the numbers and symbols of the dial mechanism described above. Fixed to the portion G10 by means of pins G13 is a ring G14. It is provided with teeth on a portion of its outer surface as shown particularly in Figures 6 and 12, and elsewhere it is provided with numerals G15 and letters G11. G12 is an aperture formed in the casing portion B2 above the ring G11 and in the numerals G15. It may be' provided with a lens G18 held in place by a frame G11. Mounted in the segmental portion G9 is an insulating member G20 which has a plurality of contact pins G21. G22, G23 are connecting wires which serve to join alternating contact pins. The connection of the pins is such that each alternating pin has different polarity; this is illustrated particularly in Figure 7 and in the wiring diagram Figure 13.

H is a leaf spring provided with a contact pivotally mounted on a pin K2 point H1 and adapted to contact the pins G21. The spring is supported from a bracket H2 attached to the base A.

I is a groove formed in the sleeve G2 ed to receive contact pins I2 which are mounted on a fork I1. This fork is pivotally supported as at I3 in a bracket I4. I5 is a generally L shaped member to which the bracket I1 is fastened and it is itself carried by a bracket member Ie which is fastened to the back A1 of the housing base by means of screws I2; I8 is a magnet coil having a core I. It is mounted in the bracket I5 in general opposition to the enlarged member or boss I1 which is fastened to the fork I1.

J is a member upwardly extending from the base A. It may be formed as a lug integral with the base. Attached to it is a generally L shaped member 1 which carries a magnet coil J2 provided with a core J3. J 1 is a boss or enlarged member attached to a lever J5 which lever is pivotally mounted at J 5 in a bracket J2 which is itself fastened to the L shaped member J1. Pivotally mounted at the outer or free end of the lever J5 is a dog J2. J9 is a lug extending from one end of the base portion of the dog. J1 is a spring fastened at one end of the lug J11 and at the other to the bracket J11 which extends outwardly and is fastened at its lower end to the member J1. J 12 is a stop pin fastened to the member J11 and adapted to limit upward movement of the lever J5. The spring normally holds ythe lever in the position shown particularly in Figure 6, thereby holding the dog J 2 out of engagement with the ratchet wheel G2. J14 is a stop pin mounted in the bracket part G5 and adapted to limit counterclockwise movement of the dog. J 15 is an additional stop pin mounted also in the part G1 and adapted to limit downward movement of the dog. When the magnet J2 is energized, the lever J5 is drawn in a clock-wise direction, causing the dog to engage the teeth of the ratchet Wheel G8 and turning it in a counter-clockwise direction. This movement is limited by contact of the dog with the limiting pin J 15. Since the ring G11 and the enlarged surface G1o attached to the segment G9 are all mounted upon the sleeve G2 which moves with the ratchet wheel G8, this assembly ofparts is given motion and this motion is controlled and limited by the mechanism just described.

K is a bracket mounted upon the base A provided with a laterally bent upper portion K1 upon which is mounted a generally L shaped member K2 and magnet K3 having a core K1. K5 is a laterally enlarged member mounted on the lever K6. The lever K6 is which is itself journaled in upwardly extending lugs K8 which in the form here shown form part of the bracket member K1 which is fastened to the base A. K1o is a printing hammer or platen is itself mounted on apawl K12.. This pawl is adapted `to engage the ratchet teeth K12 which arev cut in a' portion of the ring G11. K2o is a pivotal supportfor the pawl K12 and is mounted in a bracket member K21 fastened to the base A. K4 is a spring attached to the pawl K18 and tending normally to hold lthe pawl in engagement with the teeth K19.'

K22 is a spring, one end of which is wrapped about the pin K12, the other end of which bears against the lever K15 tending to move itin a clock-wise direction. K23 is a stop pin mounted on the lever portion K12 and adapted to limit the clock-wise movement of the lever K12. In one position the notch K16 and the lever K engage the pin K12 of the dog K12. -This position of engagement is shown in Figures 2 and 6. K24 is a leaf spring which is mounted beneath the lever K2, and

the lever.

normally holds it upward in the position shown in Figure 2. When the magnet K2 is energized, it raises the right end of the lever K2 as shown in Figure 2 and correspondingly moves down the portion K12 of This downward movement is limited by the lug K30 which as here shown is formed integrally with the base portion A. When the lever K, K12 is moved so as to draw downward' the end K12 the lever K15 moves with it and' since it is in engagement with the pin K1' on the pawl K12, it moves the latter out of engagement with the ratchet teeth K19 on the ring G14; This movement is shown in dotted lines in Figure 12. Whenthe dog K12 is moved out offengagement with the ratchet teeth, the ring G14 is then free to move and the spring G2xs which is wound by the shaft Gre thereupon rotates the ring G14 and the segment G2 in the direction indicated by the arrows in Figure 12. One of the pins the curved upper surface K2e of the leverK, and tends to move causing the dog to return to its normal position in engagement with the ratchet teeth-K11" y The movement of the lever K1 in response to rotation of the ring G14 and-contact with the y pin K2s is limited by a stop member- K2? which is mounted on the lever portion K12. .Attached to, and in this case, formed integrally with, the lever K, isan upwardly projecting lug K211 upon which is pivotally mounted a pawl L.'

It is evident that while I have shown and described a practical working embodiment of my invention, many changes might be made inproportion, size and relation of parts without departing from the spirit of my invention, and I wish my description and drawings therefore to be taken as in a broad sense diagrammatic, and not as limit= ing me to thel specific forms described and shown.

The use and operation of my invention are as follows.

The use and operation may best be followed from an examination of Figure, 13

which is a wiringcdiagram. As shown in that ligure there are two stations designated generally by the letters X and Y. The operatioifof transmission between the two is as follows: Assuming that the operator at station X wishes to send a-message to the central station he iirst pushes down the starting button D2 thereby bringing the pring leaves E2 and E2 and leaves E2 and 2 into contact with each other. This closes the spring leaves E2 and E10 and establishes a circuit from the battery a through the wires a1 a2 and the spring leaves E11-E12 and wire a2 to the time printing magnet R8 through the wires a1 a back to the battery. The operator then dials, -for example number 9 on the indexing unit which is designated on the wiring diagram as X2 while still pressing down the starting button D2. By rotating the dialing disc in a clock-wise direction, the lever X5 moves out of contact with lever X2, and allowing the spring levers X2 X7 to come into contact. The dialing disc is then allowed to return to its starting or at rest position and the cam X2 is thus rotated and closes the spring leaves X2 X12. This, takes place as often as the number dialed. When this action takes place a contact is made and a circuit established from the battery a throu h the Wires a1 a2 b, spring leaves E2 and Eg2, the spring leaves X2 X12 of the indeXing dial X2 through the spring leaves E7 and E2, the wire 1 and the paper feed magnet c2 of the substation X, thence through the wire 62 a5 back to the battery. Another circuit is established from the battery a through the wire a1 and b, the spring leaves 2, E2, leaves X2 X10 and spring leaves E11 E7 through the wires b1 b1 and the paper feed magnet k2 of the central station vY, the wires b2 a5 back to the battery.

The operation of the dial is lcontinued after the pressure is released from the starting button. The turning of the dial closes a circuit from the battery a through the wires a1 a2 and b, the spring leaves .E2 E1 contact springs X2, X", spring leaves E2, E2 the wire b1, the paper feed magnet k2, wires b2 a5 back to the battery. Another circuit from the wire b1 through the wire b4, paper feed magnet k2 of the central station Y, the Wires b5 a5 back to the battery.

Rotation of the cam X8 closes a circuit from the battery a through the wires a1 c, contact pins 101 upon the segment G2, spring leave c, wire 401, relay magnet 82, wire c2, spring leave E2 and E7, contact springs X2,

Y -1-5 and thereby establishes a clrcuit l X10 of the dial X2, the spring leaves E, E, wire c3, spring leave H. contact pins k", wires c* and a5 back to the battery. Another circuit is established from the battery a through the lwires al, c, the contact pins' k1 and the leaf spring c, the wires c1 c5, relay magnet S2 of the central station Y The wires c", c2, the spring leaves E8 and E7, contact springs X9 and X10, spring leaves E3 and lt, Wires c3, spring leave' H, contact pins 705, wires c4 and a5 back to the battery.

The magnetizing of the relay magnets S2 szrauses the attached sprin leaves to close from the the wires al, d, printing the wire d1 the spring and back to the battery a through wheel magnet 7'2, leaves se, s, wires d2, b2 a battery.

Another circuit is established from vthe battery a through the wire d spring leaves S8, 12, wire dT printing wheel magnet J2 ofv the central station Y, thence through the wires (Z8 a5 and back to the battery.

The operation of the circuits above described is used when it is desired toprint numerals, that is to say, to transmit numerals and it will be understood that in the opthe main station so eration as above described, a message 1s sent from the sub station X to the central station Y and in normal operation at each station the message is printed and a record is thus made of the message sent.

If it is desired to send letters instead of numerals this may be done by pressing the shift button F of the substation and thereb a circuit is closed from the batterya througii the wires al f, switch leaves f1, f2, wire f3, the shift magnet 10,the wires f, d2, b2, a5 and back toethe battery.' Another circuit is made from the battery a through the wires a1 f, switch leaves f1, f?, wire f, shift magnet Il of the central station Y through the wires f7, a back tothe battery. Y

It will' be understood that in the two stations, that isthe one designated as the sub station and the one designated as the central station, 'the sending and recording' mechanisms are normally identical and thus a message may be sent in either` direction where, for example, the apparatus is installed in a factory, a central station is in the office, sub stations may be established at a variety of places throughout the factory, for example, the actory. The operator of the machine desiring supplies or mechanical assistance, for example, will operate his sub-station and his message will'be recorded at his sub station, the hour, time and date beingautomatif cally recorded and his message being at the same time recorded inl 4conjunction with the date and time stamped. At the same time that this record is made at his substation an identical message and record is produced at that there is at the oilice up and refuses to function,

'prises a series at several different machines in;

information of what he wants and a record of the .fact that he asked for it with the time of a particular sort in my drawings, still many other types of printing mechanisms might be used and for some purposes it is desirable to use record making mechanism which em- I ployes no ink; one such form is that in which increments, letters or other stamps are impressed upon the paper and create in effect an embossing. y

It will be noticed that in each dialing assembly alternating contact points such as K1 and G21, as shown in Figure 13, are of dl'erent polarity. This is done as a precaution so that if for any reason not move in harmony, one of the circuits will n'o dead and it will be necessary to commence ialing from the beginning again. l

The segment Gr9 may be referred to as a commutation type switch and it will be noted that the segments are so' relatedmechanically that they move in unison and the wiring circuits are so disposed that when the circuit is closed on one of the commutation switches through positive battery, it is closed on the other switch through negative battery and vice-versa; and as the switches move from point to point in unison, each switch steps from positive to negative and vice-versa. If for any reason the commutation switches get out of step and-we have both switches on positive or both on negative, immediately theapparatus controlled by the switches ties thereby preventing improper operation.

It will be further not/ed that the transmis;A sion of signals between the two systems is eil'ected by a continuous series of impulses Vas distinguished from `interrupted impulses or from intermittent impulses.

Discrimination between signals is effected by the numerical number in a series of impulses. For instance, the impulse used in transmittingsignals in my apparatus com# of opening and closing of the circuit. An impulse consists, for instance, of a closing of the circuit for 'f-G of a second and an opening for To transmit the letter C for instance, three impulses will be given, taking a of a second because each impulse lasts ,16 of a second.' During each of these impulses the circuit will be closed 7 100 of a second and open/lOO of a second. These are nominal values selected for example only.
