'T all whom ii may concern:-

Be it known that I, BAsILE S0LDA'rnNcoW',-. D

0t 37 Rue La Prouse, Paris, Fr'ance,';have invented certain new and useful Improve nents in and Relating. to Printing-Telegraphs, of which'the following is ,a-spe'cifica The present invention relates-to a print-i ing telegraphic device, comprising an elec tro-magnetic device having-two dlstinctabtions and provided with a single solenoid by which-means it is possible to obtain difier'ent and distinct effects. It is thereby'possible to reduce the consumption. of ,current, as .Well.

as the size and cost of the apparatus.

The accompanying drawingsshowbyway 1 of example a transmitting and-receiving ap= paratus constructed alcoordingto the invent-ion. M

Figure'l is a diagrannnatic yiew of the electromagnetic device according to thein-- ventlon. Figs. 2 to t illustrate an apparatus embodying the invention at different stages in its operation. Fig. 5 1s a transverse sec tion of aprinting telegraph c lnstrument sectional side elevation .along line 2- 2 ot- Fig. 5. Fig. 1 is a section lon line 3 333of Fig. 5. .Fig. 8 is a plan with part of the keyboard and: its supporting plate removed; .Figs. 9 to 13 show details. Figs. l:t' and 14? are diagrammatic views of the various connections; Figs. 15 to 18 show a device forsetting transmitting and receivi'ngapparatus in concordance.

The electro-magnetio device according to theinvention consists (Fig. l) of a solenoid .A-towhich current is supplied by an electric circuit B (the source of current being at I).

The circuit B is divided. outside the solenoid and-includes in one. of the divisions C a switch or other device D which only permits such current to pass that the magnetic field generated shallbe suificient to produce a given attraction or magnetization of the core 'G--. In the other division of the circuit E is inserteda switch or other device F which permits such current to pass that the magnetic field generated'shall be sufiicient to' cause a stronger attraction or magnetization than the first, for the-purpose of obtaining by means of a'single solenoid and a single electric circuit different and distinct effects.

The apparatus acts as follows,. supposing '55 that the core G is attached to a fixed point J by means of 'a spring H whose' tension is v j Specification of Letters Patent. i Application filed February 5; i912.

Figs. 2 to- 4 can be used. A; represents a solenoid or electro magnet havinga station-.

'ary core 80 and a'movable core- 81.. One of the divisions of the electric circuit'is con stituted by wire 82, starting from the source of current 83 and having a suitable switch8 l, a bracket 85 on which is pivoted at 86, a conducting lever 87 havingv a spring contact member 88, which: latter can contact with a conducting lever 89 mounted in a conducting bracket 90 connected by wire 91 to" the solenoid A which finally is connected to the source of current 83 by the wire 92. A nonconducting extension 93 oflever 89 is pivoted at its extremity to the movable core 81. The contact member 88 is mounted in a casing 94 which can be moved along the lever 87. The latter carries an insulating: piece 95 placed. between an adjustable abutment .96, mounted on. the endof the lever 89, and a second adjustable stop 97. A. counterweight.98 whose-position can be adjusted is nounted'on the other end of lever 87 and returning springs, 99 and 100 are fitted on levers 87 and 89 respectively.

The'second division of the circuit is constituted bythe wire 101- connecting the two points 102 and 1 03-of the circuit andinclud' inga switch 104e.

In Fig. 2, the switch 10% sopen (the usual In practice the arrangement shown in the "Same kind are obtained with the switch key 84 being depressed) and thecircuit is the. following: wire 82, bracket 85, lever 87,

- spring contact 88, lever 89, bracket 90, Wire 91, the winding of the solenoid A and wire 92. The movable core is therebv attracted and together with lever 89, 93, takes up the 1 position shown in Fig. 3. The stop 96 raises the insulating block 95 and swings the lever 87 and thereby removes contact88 from lever 89 and interrupts the current. The

n V I core 81.1s now no longer-attracted and the springs 100 and 99 return the corresponding levers 89 and 87 into the positions shown in Fig.'-2, thereby again closing the circuit, in

that contact. 88 makes contactwith lever 89. By this means the core 81 is again attracted, ,wh-ich attraction again'breaks'the circuit, and this cycle of operations continues/indefinitely. In this way a rapid pulsatory movement of the movable core 81 obtained by the rapid succession ofo'pening and C103? ing of the contact making and 'breakingde- ..vice 88-89 If the switch 104 (Fig. 4) is closed'the following circuit is formed: wire 82, branch 101-,switch 1042,- wire 91, solenoid A and wire 92 thereby producing in the solenoid a magnetic field whose intensity can be regulated .(.for instance by' the time during .which the current passes) so that it is greater tha'n'that 1 of the field produced by the first branch,

Therefore by closingthe switch 104 during theoperation of the contact making and breaking mechanism 8-8 -89, the more in;-

tense field-controlled by 104: will cause the movable core 81' to be stopped or held, while at the same time magnetizing the core 80 I more strongly. The extent and duration of the movements of the core 8l can be regulated by adjusting the stops 96 and 97 and .the counterweight 98. In certain cases, a

movable armature 105 can be arranged near the stationary-core 80, in order to utilize the magnetization developed there and to make it actuate, either'directly' by magnetic attraction, orby any other suitable means, the

switch 104; in order for example to open said switch, after the current'has passed for a vpertain length of time. This armature could "III the same way actuate in any suitable manner, the device for closing switch 84.

Incertain other applications, the stationary core 80 is given a form adapted to enable it to actuate any other desired device, either directly by magnetic attraction or indirectly *byan'ysuitable transmission gear. The core r may, for example, be' provided with "heads or projections of any suitable form. One

could also cause the switches 84 and 104to cooperate so as' mutually to control their .maneu'vers under certain conditions. An

. adjustable stop may be arranged above the movable core 81. One couldalso arrange, in

each branch of the'circuit supplying the solenoid, SL'SWItCh, either actuated ornot,

or;of' feeding a core or armature.

a resistance, any. source: of current -or any] other device adaptedeither, to vary the mag; netic field of the solenoid by controlling the I duration of the period of passage of the current, or in any other manner'by controlling the current itself, or ada tedto control other-' organs of the device. T e solenoid or electro-magnet can be replaced anywinding or coil capable of creating a magnetic field The transmitting instrument shown comprises a key-board Aand acasing B which latter has an intermediate partition C, so that a chamber orspace D is'formed. The mechar'am comprises a magnetic device having a double action, the reciprocating movement of the movable core being utilized to bring the type or printing characters carried by a wheel into printing posit-ion, whilethe attractive movement of the armature of the fixed core serves to effect the impression.

The keyboard A has a. suitable number of keys a (Fig. 5), each of. which is mounted on a vertical lever b guided in the upper walla.

of the keyboard casing and recessed so as to form, on the one, hand, a cam dadapted to actuate a horizontal frame e and,on the other hand, an abutment 7 which is adapted to sink below a second-frame g. The two frames 6 and are guided in the casing 'of the keyboard by rollers h and are provided .with returning springs (not shown) which tendconstantly to return them to the posi tion shown in Fig. 5. The frames are perforated to allow the passage of the rods 6, and these perforations are sufficiently large to permit movement ofthe keys. Each rod?) has an extension z'which-serv'es as'a guide to a returning spring 7', and passesthrough the .mis arranged a'cont act member 9, supported in a plate rof'insulat-ingmaterial and connecte d by a wires and a'metal rod M which passes-.through'partition Gto'a contact member 7) fitted oil-the inner face of this partition. I These contacts iowhich correspond in numberv toithe keys a are arranged in a circle andiiisulated one from the other, each one bemg connected in the same way, to

the various contacts correspondingto the keys a of the keyboard. '--The upper fra-me e is provided at its inner. end with a'vertic'al insulated arm w carryinga horizontal rod 3 placedopposite a spring contact 2 whlch is situated near 'a-fixed contact tconnected .to

lVhen utilizing the device described on a telephone line, or on a telegraph line, it may happen that communication between the two stations .is. cut at the moment when a message is being sent, and that the receiving apparatus alone receives current and continues to act, so that the brushes of transmitting and receiving apparatus become relatively displaced. in order to remedy this drawback, there is provided an apparatus for resetting into concordance. .In order to insure the synchronous working of the apparatuses, the latter are arranged in the manner shown by the diagramof Figs. 15 and 15. The free end of the lever 22 which supports the movable core 20 of the solenoid 16, isprovided with a head 106 opposite to two contacts 107 and 108 connected with the and terminals respectivelyof a source of electric current and from the said lever, insulated from the mass, starts the wire 109 of the line which latter, for each apparatus passes through a relay 110 of any suitable construction, the armature 111 of which is connected with the supply of a local source of electricity and is adapted to bear against a contact 112.com nected with the inlet wire 2 of the coil 16, for one direction of the line current. 'Owposed as being a transmitter in Fig. 15,

assumes the position indicated with dotted lines, the head 106 being in enga ement with thecontact 108 of the source a cur rent in the direction will be sent in the line, said current ending at the ()t er- -'1ninal of the right hand apparatus and pass ingthrough the relays which are energized and brought into their working position,

whereby a local current will be sent in each will assume a position symmetric to that in-' cheated by the dotted lines. In this displacement the heads 106 have reached the 1 contacts 107 in consequence of which the line is supplied with a current flowing in. the (-1-) direction, that is to say'starting from the (-1-) terminal placed at the left and ending at the terminal of the left.

hand. apparatus. The direction of the currnt in the line being thus inverted, the,

armature 111 of the relays is pushed back I in-the other direction thus cutting off the supply of current in the wire 2 of the coils, causing the springs of the cores .20 to re turn thesaid cores in the position of rest movable cores, cutting '01? again. the line cirindicated in'dotted lines. A current inthe i r (-1-) direction is thus again sent into the v line, the relays produce the attraction of'the engageiwith :a ratchet Wheel-119 keyed on I 130 arranged iii-{- a onve ientpmanaen The t spindle 12(1passes across thezhwa'll offthe box I and "externally to the said qbo'x "it ghee-rs a needle r31 aSIWll: awn operating knob 132.

If the coils of the apparatuses Whichare.

For example, if the left hand. core in -Fig. 15'has tendency to. oscillate more quickly than the right hand apparatus, and if it has been returned to its position ofrest symmetric to that indicated by the dotted lines When'the core of the right hand apparatu's has reached the position indicated in dotted lines then the current sent through the right hand apparatus in the Y line is unable to flow-through theline because it Wouldend at-the terminal of the apparatus placed at the right hand. I Thus, no current whatever is circulating in the line. and as not any influence changes H the position ofthevr'elays, theenergizing circuit of theright hand solenoid remains completed until the attraction of the core hastaken place anduntilpthis core has again been returned into its position of rest'whichi is symmetrictothat. indicated by the 'dott ed lines.

The operation .is the following: At rest, each apparatus is in a so-called receiving position to which corresponds a determinated position of the switch 125, which must be so, that the apparatus is able to receive at any moment a-despatch from any transmitter. When any apparatus is desirbus to send a despatch the direction of its double switch is reversed whereby the polarity of the endof the line and of the relay is changed, and the despatch can be forwarded withoutany necessity of specially pre aring the receiving apparatus, being un erstood that the necessary connections have been previously established. When the I transmission of the despatchhas come to end, the operator returns the switch to the position of'rest or receiving position. A despatchcould however be received through this. apparatus even ifthe reversal of the 'poles' has not'been efi'ected. In this case it would be suiiicient that the operator of anyother apparatus, acting as a transmitter, by observing that his apparatus is unable to work when connected with the aforesaid'receiver, changes the-position of his switch to pbtain the working of the two apparatuses as may be easily understood. In this case the 7' stationary core to the printing device, is providedwith a suitable device not shown,
