To all it may concern: I.

a subject ofthe German Emperor,-and CARL MUEHLEISEN, a citizen of theUnited States of Americafresiding, respectively, at Berggartenstrasse, No. 17', Dresden- Blasewitz,

and 88;.Chausseestrasse, Berlin, in the'German Empire, have invented new and useful mprovelnents inTypographicalComposin Machines, of which the following is a spedis fication.

. This invent-ion relates i to typographical composing machines oft-heclass in which the matrices or devices to. be composed, are

stored inchanneled magazinesgand are re-- leased one at a time from their respective magazine channels, byeseapernent .mechanism operated or controlledby finger keys actuated by the operator.-

So far as the present invention "is con cerned it matters not whether the machine is adaptedto compose matrices, type dies or type, and for that reason, the word matrix or matrices as herein employed, is

intended to include all of such devices. A

: well -.known example of the above-named class of composing machine is that commercially known under thetrade mark Linotype, and for convenience of illustration, that machine has been selected as the one in connection with which the present invention is herein described.

The object of the present invention is to provide improved means whereby matrices can be released alternately from. two differ-' ent magazine channels by successive operations of oneandthe same key, and the in vention-may be said'to consist-in these means being so arranged that the longitudinal I 'domrnon to two magazine channels, shall ef-- j gnovement, of an escapementrrod or reed fect an automatic transference of the said rod from operative relationship with the es-} capement of one channel to operativerelationship with the .escapement' of another channe To avoid unnecessarv re etition the word transfer or transference is hereinafter used for denoting the just mentioned move p v Specification of Iietters Patent.

In the embodiment of the invention represented in Figs. 1, 2, 3 and 4, the escaperhentrod 1, which is common to the escapement levers 2, 3 of two adjacent magazine channels 4 (only one of which latter is show'nlin the drawings, see 4), is provided with a pivot pin 5 OIIXVlllCll is pivoted the upper end of a link 6.- At its lowerend the link 6 is provided with a slot 7 engaging with a pin 8 fast to a tilting lever or weight 9 pivoted by a pin 10 to a bracket 11' fast to:a plate 12 which is penetrated by and servesto guide, the rod 1. The lever or weightS), hereinafter referred to as a weight, is capable of swinging from one to.

the other of the two. terminal positions in which it is respectively represented in Figs. 1 and 3, the plate 12 serving to preventit from moving beyond these terminal positions, 'Theescapement rod 1 is operated 1 sented'in Fig. 1. When, now, thekey" lever through a key lever 13 and the usual intermediate mechanism, not represented in the drawings, and at'e'ach depression of thiskey lever, the rod 1,'besides being'raised to effeet the release o'f,a matrix 14 from the re- 1 spectivemagazine -channel4- as ordinarily, is transferred from beneath the-escapement lever2 to beneath the esoapementlever 3,

' or 'vice 'versa. This transference of the rod 1 is effected in the following manner. Let.

it be assumed that the rodl is-in operative relationship with the escapement lever 2,

and that the said rod, weight 9 and other coiiperating parts are therefpre'in the positions' in which they are respectively repre- 13 depressed, it raises the escapement ro 1 and escapement lever 2, and at the same time, through-the link-6, jerks the weight 9 upward so that it acquires sufiicient momentum to carry it from the right-hand to;

the left-hand side of its vertical position'as indicated in Fig. 2, during which motion, the pin 8 hasvtraveled up and down the slot 7. After this juncture, the pin 8 is at,;the

"lower end of the slot 7' so that the descent,

or continued swing of the weight 9 serves to carry'the upper end of the escapement rod 1 toits left-most position in which it is be-- 'neath the esca ement lever 3 as'shown in- Fig. 3, the said weight during this latter @part of its motion, serving also. to assist in loweri the rod 1 to its normal position;

7 When t e key lever 13 is next gdepressed the escapenient lever 3,,1s actuated and the .j weight"9 is swung. rightward and servesito "move the iescapement -rod- 1 from beneath that lever to beneath thefilever 2;. ,,again, at-n the next succeeding depression of the key lever 13, the weight 9 is swung leftward as previously, described with reference to Figs. 1 to 4, By these means therefore, successive depressions of the key lever serv'eto release matrices alternately from two difi'erent'magazinechannels 4 and. at the same time automatically effect the before mentioned transference'of the escapement rod 1 from operative relationship with one to the spectively" shown in 5, then the-ifirst depression of the key lever 13 will effect the operation of the escapement lever 2 in the V ordinary way, vand will alsojerk the heavier" endof the weight 9 upward and toward the i inent lever 3. At the next ensuing depres sioniof' the key'lever 1, the escapementlever 3 is operated,the weight 9 is swung rightward and the escapementrod 1 is moved out of-v opera'tive relationship with the escape-' ment lever 3 andainto operative engagement with the escapeinentilever-2; :1

In the embodiment illustrated in Figs. 6; in

,numeral 21 is us'edto denote it.- The pivot 120 is supported by-a braeket or arm 24 fast 9.5

ito, ,and extending downward from the plate l2r-the said arm being-provided--- with two ,stops 25, 26 for limiting the motion of the switch 21 at its-'twoitermina'l positions (see vided with a hook 27 to which is attached" the lower end-of a spring-"28 whose upper? end .isattachedto the swltch 21 at a point 29 above the axis? of the pivot '20. Thehookr27 is situated 'inthe same vertical 1 plane-as is the pivot-20, and as the point 29 {swings t0'I-'6itl16 1 side of this -plane, the

spring 281willjserve-to retain the switch 21 in its two terminal positions with justslifli c'ient force to preventaccidental reversal and yet to admit of the said reversal being auto y matically effected by each descentf-of the other of-the two respective escapement 50 levers 2,3. y I, a m

- 1 Instead of the weight 9 being capable of turning upon a stationary pivot 10 as in Figs; 1 to 4, it can, as shown in Fig. 5, have its-pivot fast to,-and movable with, the retheescapement rod lfbe in position for operating the escapement lever 2, as indicated;

the position-{in whichitis represented in that figure, that is to say,the tongueo'f the escapement rod l. -If-itbeassumed that i in Fig.*7,thh the switch 21 will als o'be m I spective escapement rod 1. In this arran ement, the pivot 15'=is situated between t e two ends of theweight 9, and the upper end of the link dis ivoted to one of these ends by a pin'lG, wh e the lower and slotted end of the link is free to'slide-upon-ahstationazy pin 17 fast to a bracketJlB rigidly secured to the plate 12'. I'I theadifierent partsof last described arrangement beassumed thepositionsin which they are resaid switch will be held lay-the spring 28 be at the right, of the tongue 21 ands-bearing on the arm "23: When, therefore,- the e's;

the pin 19 .andthe rig t hand side of the tongue 21,

slightly toward;

against the stop 26, and the pin 19 will capement rod .1 is next raised, it operates the escapemeht lever 2 in the usual way, and

asses'up'between' the stop 26 which, in consegpence thereof, is turned e left agamst "the action of. the spring 28, which latter returns the,

tongue 21 .into contact with the stop 26 as soon as the pin has passed between them. At the immediately following descent of the escapement-rod 1 the pin 19 slides down the left-hand side of the tongue -21 which, acting thereon'as a cam, causes the said rodtobe; deflected toward the left so that its upper end shall be beneath the escapement lever 3. This descent of the rod 1 also causes the pin 19 tobear on the switch a m 22 and thereby to tilt the switch 21 from the position in which it is shown'in Figs. 7 and 8 to that in which it is/shown in Fig. 9. At the next ensuing. operation of the escapement rod 1,the escapement lever 3 is operated,the pin; 19 passes up between the stop'25 and the left-handlside of the tongue 21, and descends along the 20 right-hand side of the said ,tongueso that the escapement rod 1 is'later'ally deflected from the position in. which\it, is shown in Fig. 9 to that in which it is] shown. in Fig.1

7, these lateral deflections f the escapement rod 1 taking placeat eech of its de scents.

' In' the embo diment illustraed in Figs.

10, 11'and12, the escapement. r d 1 is pro- Y .vided witha pin '19, as in the mbodiment 1 so herein last previously described} which (30- operates with a switch for e e'cting the before mentioned transference of rod. .In this embodiment, the swi ch 30 is in the form of a double taper or wtdge the thicker and upper end of which is pivoted on a stationary pivot 31 on which t e said switch is capable of turning from e to the other of the two terminal positions represented respectively in 10 antl 12. The escapement rod 1 is providedwith two 7 arms 32, 33 which, during the descent of the said rod, engage with the upper end of the switch on e ther side or its axis of osclllation so as to rock the said switch from one to the other of the above-named terminal positions.

Ifit be assumed that the lastdescribed devices be .in the positions in which they are respectively shown in Fig. 10, then thenext ascent of the escapement rod 1- will cause the pin 19in travel up the right-hand side of the switch 30 and in so doing will also cause the said. rod to be deflected escapement lever 3; to. beneath the escaperightward Hfron'r beneath the ment lever 2- and to tilt. the switch 30. into, the position indicated'in Fig. 11, the continued' upward movement of the escapement rod 1 serving to operate the last named lever (2) also as shown in Fig. 11.

During the descent of the rod 1, the pin 19 passes down between the right-hand side of the switch 30 and-the adjacent stop 35 and by the time that the pin 19 has moved clear of the switch, the arm has reached the the s'aid k top ofthe said switch and, by its continueddownward moement, this arm cants the switch toward the right so as to bring its pointor lower end into contact with the stop.35, all as shown in Fig. 12. At the next ensuing ascentof the rod 1, the pin travels up the left-hand side of the switch 30 and thereby deflects. the said rod leftward so that its upper end passes from under the escapement lever2-to beneath the escapement leverr3. In this way the pin 19 causes the switch 30 to tilt so that its lefthand side is practically vertical and parallel with the adjacent stop 34. During the next following descent of the escapement r'od l the pin .19 passes downz'between the.

switch 30 and the .stop 34, and by the time that-the said pin is clear of the switch 30 the arm 33 has reached the top ofthe latter and by' hearing thereon, tilts it toward the leftinto the position in which it is arrested by the "stop 34,so that at its next -followmg ascent, the rod 1 will be again deflected rightward as before described.

, In the embodiment illustrated in Figs. 13 and l l, the escapement rod 1 is provided with a forked bearing 36 within which is roto each other, so that when an arm of the star wheel .37 is in position for operating the respective escapement lever 3,'no arm of the starwheel 38 will be in position for operating theescapement lever 2 and vice versa.

A spring pawl 40 fast to the plate 12, projects into 'thedownward path of the ratchet wheel 39 so that at-each descent of the escapement rod 1 the said wheel is brought into contact with the pawl 40 and is rotated thereby, through an angle corresponding to that between any two adjacent arms of the wheels 37, 38, that is to say, in the example illustrated, an angle of 15 degrees. A

spring detent 41 fast to the escapement rod 7 1 and engaging with-the ratchet wheel 39, serves to retain'the latter and the star wheels 37, 38 against accidental rotation. The last described arrangement operates as follows, it being. assumed that, at the commencementof such operation, the different parts of the arrangement are in the positions indicated ascent of the escapement rod 1 and wheels 37, 38, 39, the ratchet wheel 39' is moved away from the pawl 40, and the upwardlyits in Figs. 13 and 14. At the next following presented arm of the star wheel 37, acts on 'i the escapement lever. '3, as though it (the said arm) were actually the upper extremity of the rod 1, and thereby effects the release 1 of a matrix 14inthe'ordinary way. \Vhen the'rod 1 descends, the ratchet wheel 39 is such descent, engages with a stud 42 fast to brought into contact with the stationary I pawl and is thereby turned about its axis through an angle of; degrees thus moving the star wheels 3.7.and 38, into respectively inoperative and operative'positions, so that at the next-following ascent of the rod 1,

"I the escapement lever '2-will be operated,

ment rod 1 from one to-the other of the escapement levers 2, 3 is effected during ,the-

-while the other t-ionaryi In the embodiment represented in Figs.

15, 16' and 17, the transfer ofthe escapelever B- will remain sta descent of the said rod, and for thispurpose, a spur 41 fast to the rod. 1, at each one end of a two-armed lever 43 which is pivoted upon a stationary pivot 44, and

-. whose other end has-pivoted to it, a pawl 45 ing .aboutja fixed axis. This ratchet wheel which engages with a ratchet wheel 46, turn- 46, through its shaft 47 or otherwise,is rig idly. fast to-a cam 48 which is formed with half as many projections; 49 as there are teeth inthe ratchetwheel 46; 50 is a lever capable of rocking upon a stationary pivot .51, and carrying a pin 52 which is held con- 1 .stantl-y in contact with the periphery of the cam 48 by" a'gblade spring 53. To the upper end of the lever 50 is pivoted a guide plate a 54 which is freeto slide horizontally on the topof theyertieal plate 55 which-alsorserves to -support -rthe before mentionedv shaft47. The guide-plate 54 is attached to the vertical plate 5 5,jby-a pin-and-slot connection which admits of it (thesaid guide plate) moving only in .a, longitudinal direction, and it is provided with an opening through which the upper.end of the escapement rod 1 is free to slide. If it be assumed that the'diferem parts of the last described arrangement be in the positions in which they are respectively represented in 15,.then the operation may be describe as follows. \Vhen the escapementrod 1 is raised, it operates the escapement lever 3 in the ordinary way, as shown in Fig. 16, and when it descends, its spur41 engages with, and

' depressesthe stud 42 and thereby raises the "cam .48 which depressions are situated be-" pawl 45=and turns the ratchet wheel 46 to the extent of'one tooth and thus presents to the pin 52, one of the depressions. of the tween the before described projections 49. The lever. 50is thus allowed to move rightward under. the pressure of the spring 53 andthereby to transfer the escapement rod 1 frorn' the escapement lever 3 x to the lever 2 as shown in .Fig. 17, so that at the next fascentof the said rod, it will operate the escapementlever 2. At'thenext following descent ,of the :escapement. rod 1, the-{spur 41 again engages theastudflQ-and effects a" pargfial rotation to present a projection 49 (instead of a depression) to.
