i designed to automatically transmit any well Vknown or selected code of signals.

The object of th'e invention is to construct a transmitting machine which will continuously and automatically transmit telephic symbols at a uniform rate of speed independently of the speed at which the key board is operated, and which will enable the operator to accumulate or store u successive groups of telegrapbic symbos in advance of their transmission, end which furthermore will allow of the transmission of the first aynibol immediately after lt has been eet up, and the continuous transmission of the successive symbols so long as the key hoard is operated, thereby svol ing all loss of time in transmission.

'l'he invention, generally stated, comprises:

a key hoard selective mechanism and a trcnstnitting mechanism, the relation between the two being such that the selective mechanism acts to siniultnneouel set tip all the parte of a tele raphic symbo the regular transmissinn o, successive groupe of symbols bv the transmitting mechanism not icing affected hy tbe speed at which the selective mechanism is operated.

The key board selective mechanism compriaee a eet-ica of selective lbara under the control of the key bara, said selective bars being constructed with' projecting lugs arran l to correspond with the telegranhie sym iol of the character of the coi-respalding key har which controla it.

The ,transmitting mechanism by which electrical impulses of variable length are sent over the line, comprises what I have termed a storage wheel 'which wheel is provided with n series of :pinol ndjustahly supported thereon and at equal distnmees spurt. 'lhese ins which muy he arranged to he inoved on itudlually either vertically or hoeiaonl tal y. or pivotallg mounted, are adapted to be moved by the operation of the selective hars in groups and so arranged that the pilon of each grou hall corres tra hic sym the ey board. The storage wheel is adapted to be rotated by a continuously driven source of power and is automaticallycontrolled in its movement by the kev bers, the construction being such that said wheel is held in a position of reet when a telegraphic snbol is being set up and released so as to ro tated when the operator releases a key ber. The pins which are acted upon by the selective mechanism are all moved a like distance and when adjusted in goeition are ada ted to operate a make and reak' lever by w ich an electric impulse to transmit a ot or n nd with the telol of the c iaraeter struck on dash is sent over the line.. The normalitions of these ina with relation to said ever is such that s ould the storage wheel be rotated when the pins are in their normal postions said lever will not be actuated and no lmpuloe will be tranlmltted.

'lhe transmitter make and break lever above referred to is so arranged relatively to the loro e wheel un to he rotated in tlm sume direction un the direction of rotation of the storta e wheel when the latter is intormittentlv at vanced after; the settin up of a symbol but at a less rute of speed t an mid wheel is advanced. 'l`he normal position o? said "lever when it und the storage wheel am hoth at rest is immediately in advance o? the lirst pin o' the first symbol about to' be' 4set up, und when the storage wheel is brought to rest after having been rotated to advance a symbol. said lever immediately begins an independent return movement toward its iiornnil position. lf the interval between striking sneeessive heya on the key board ia less than that of the period of transmission then the return movement hf said lever will he arrested and it willngain he given en advance movement with t n: storage wheel. only tohegin a return movement when the lstorage wheel is again brought to rest. Un'- der normal conditions of operation the make und lu'eakllever is lit-pt oseillatin'g upon its axis through variable uri-s. returning to its iioriiml position only ut the end of n message or when the interval between the striking of suecas-sive kevs is snllieient to allow it to travel the full diotanee to reach its normal ioiiition. By rein-ion of the relative arrangel nent of the several parts and the speeds nt i which they are olperated, the operator is enahh-d to ai'vuniu ate symbols on the storage x whiil so tliiit tlic transmission of the iiyin- 'i hols is ctl'ecteil both when the iitoriifge wheel is living roti-.ted to advance a symbo and when 2 it is iit rest while o s nibol is being set up. i 'I'he mechanism by which the storiige wheel is iiltciiiiitcly locked and unlocked in operaitively connected with all of the key barn in such nninner tlmt the length of the symbols iheninelves determines the distance the atoriige wheel is rotated after it has been ro- 'l'hc invention willlie understood by reference to the iimiixiipiinying' drawingii in which l Figure l is ii plain view of my improved iriiiisniittcr: Fitz.

This selection ia purely arhit -ary may be` varied us desired. v ,lt is, however. tamvenient in that the mininnun number of ius is required for any given character. 'or example. ns shown in Fig. 12,-the letter A of' tte Morse code being represented by a dot and ashort dash, the bar 1l corresponding to that character will have three lugs l0 so arranged 'as to act simultaneously upon three wires 14. one wire I4 between the one for the dot and the two for the dash being idle. movement of that har'll will, through the wires 14 simultaneously uct upon three of the hell crank levers 18 so as to raise one pin representing tho dot, the next plu remaining down in its normal position nml the nextl two pins being vaisedror n group of four ius. The leta long space uml a ot, will require its lever Il lo havetliree lugs lil, so arranged that tuo act upon two wires 14 separated by an intervening idle wire. and the third lug on a wire for the last dot aspirated from the others by two intel-venin idle wires to represent the long space. his symbol requires a groupof six pins lu the storage wheel, thut is, one up, one down. oneup, two down in theinuornml munitions, and ons op.

V'lhe letter represented by a lonf'dash will yrequire its bar l1 to have. four gs so arrangedv us to act upon four consecutive wires 14 thus raising a group 'of four consecutive ius in the storage wheel, it'bein evidenttv at it two `pins are adopted aa the -unt for a short dash, the long dash will retptire `four pins or double the number of pins for u short dnsh. The letter M represented by two short dashes will require its bar tll to have four lu l0, so arranged that the first and secon act upon two contiguous wires, and the third and fourth on two contiguous wires separated v from the first set.by an idle wire, so aa to set up in the storage wheel two contiguous pino `for the first dash, one down in `its normal position for the short space'and two up for the second dash. or u group of va pins. The letter 0 representan by two dots with a ylong space between will require its 'har ll to have two lugs so arranged as to act ,upon two wires separated -hy two idle wires, ao as to set up iu thc'ntorage wheel one piu up for the first dot. two dor/n for' the long sparc and one up for the second dot, or u group of four pins.

In Fig. 10 the bar l1 is shown as connceted with ,the key bar of the letter I. In a similar manner all of the other bars ll have their projecting luga l0 so arranged as to simultaneously act upon the proper wires to set up tha desired grou ot' pula in the stor- `age wheel. and b v ting u it is tobe understood that I mean not.ou y the raising the plane of the upper surface of t s storage wheel to transmit a dot or a dash, but perremain in their normal poaiti for the avlnbol s ees, for it iajuat as essential in the pra ies' of my invention that certain pins should be permitted to remain in their normal positions to transmit short and long wheel.

As shown in t ie drawing a a inbol requiring a group of ll'i pins iis provided 'for although it la obvionii that ii greater number of wires I4 inay he used to e ect the setting up of a iiyinbol requiri any number of pins. The bar 11 connecte tothe spacing bar has but one ln t actupon a wire 47 (sec Fig. 10), said wire 47 bein operated not only by the spacing bar lint a so by all of the bars 11 azi herc- 'iiiafter described. It may be stated here that the storage wheel mechanism is so arranged as tio rovide for the csoapcinent of three pins in t eir normal positions after thc pins of each symbol have been set up. When the space har 51 is strncli: its corresponding bar l will set upon the wire 47 to allow the storage wheel to move the ii mee of one pin, thus making the tour ins own which,

aa above stated, represent. t e space between words.

The series of lugs It) on each bar begins near the outer end of the bar, the initial lugs bein in alinenient. The wire 47 lies between ie initial lng and a shoulder on the bar and is moved b said shoulders when the keyboard is manna ly operated.

.\s shown by dotted inca in Fig. 1 the levers b converge' toward the rear vfor the purpose of bringing t e. selectivo bars 11 close together or near t ie ceiitereof the wires `l-l in order to get an even notion on said wires.
