TYPOGRAPHICAL C OMPQSING AND CASTING ,MACHINE.

To all whom it may concern.-

'Be'it known that we, 'HERBERT PEARCE and JOHN ERNEST BILLiNGTON, subjects of of the United Kingdom of Great Britain and Ireland; and both residing at The Linotype. and MachineryWorks, Broadheath, in the countyof Chester, England, have invented new and useful Improvements in Typographical Composing and Casting Machines, of which the following is a-speci- This invention relates to' typographical composing and casting those known as linotype machines, and more especially to those linotype machines which are provided ii'vith both a number of superposed magazines, and means whereby, by a or operation on the part oft-he operator, an operative substitution of the magazines canbe effected simultanestitution calls for it, will cause the linotypes next cast to havea. greater or less'body dimension than that cast'lmmediately 'befor the said adjustment.

The present invention, J among other things comprises means whereby the linotype trnnming knives may be automatically adjusted correspondingly with the abovenamed change of body dimension, andimrices. in the magazines.

for each of the magazines on the machine. The connections of the several font keys 6 with their respective-magazines being all practically alike, the following description of one will apply equally well to each of them. The font' key 6 is pivoted at 7 to any convenient part of the machine frame, and is located in a position convenient for ,manipulationbythe operator. The key 6 is 1 connected, through,- a: link 8, With one. end In these drawings, which are: of a more ofa bent.

and Fig. 6am drawn to an hand side of the improved machine having 4 g riage 11 in a manner similar totho se now used in. connectlon wlth theescapement rods- -of ordinary linotype' machines, and like those cams, its weight is so distributed that, when the said cam is in its normal position, as shown in Fig. 1, thereis a preponderance of weight which tends to turn the cam in a direction which, as regards Fig. 1, is'the reverse of that followed by the hands of a clock. To retain the cam in its normal position against the influence of the said weight-v preponderance, an abutment or shoulder 1s provided on thesaid cam, which is adapted groups provided for, is' six. Over all of the cam carriages a pertaining to each of.

' thesaid groups of out keys, there isproment, would occupy those slots;v

vided a plate 16 preferably pivoted near its rear edge to the machine frame, upon a pivot 17, this plate being tilted upward whenever a cam carria e .of the correspondiiilig group is raised. [T is plate 16 serves to e ect the stoppage of the mold wheel 18 at the particular part of its rotation at which a mold 19, 19", etc, Fig. '5, having the body dimension appropriate to the selected font, .is in the ejectlng position, it being here ex- 40- plain'ed that the ,mold wheel 18 carries a number of molds of difi'er'ent body dimensions such number .corresponding with that of the above mentioned groups into which the font selectin mechanisms are divided.

Eac [of the earns spective lever 23 and is adapted, through devices including a clutch lever 26 and clutch rod 27, Fig. 1, to unclutch a spur whee '28 from its driving mechanism and thereby 'arrestthe rotary motion which the'said spur wheel 28, through a pinion 29, transmits to the mold wheel 18. For instance as seen in Fig. 11 each cam 25 may be adapted to swm a respective projection 167, 168 or .169 into the path of a projection 173 upon a lever 174 pivoted at 175 in a bracket 176 fixed upon the wheel 28. The free end ofthe lever 174 is movable between guides 180 and the inward movement of the arms carrying the projections 167, 168 and 169is made against the action .of blade springs 172. The wheel 28'is free to revolve upon a fixed hollow shaft 178 as is also the wheel 184 constantly'driven from the so-called" intermediate-shaft. he clutch rod 27 can slide in .the' hollow sha 178 and carries two arms 182 furnished ith coned rollers 186 which are pressed agai st the wheel 184 bysprings 181 and 188 this wheel in turn pressing a flexible disk 184 a ainst the wheel 28 and 'so clutching it. T e spring 181 ressin one end of the rod 27 forces the other en against the lever 174; 191 is a fork for moving the-arms 182 in the slots 183 in the shaft 17 8 when it is'desired to unclutch the wheel 184 from the wheel 28 at whichtime the s ring"191 will retract the lever 174. It wi 1 now be obvious that when a cam 25 is raised the respective projection, such as '169 as shown, will be protruded into the path of-the projection 173 and the lever 174 will be forced'back by theimpact of 173 against v169 thereby moving the rod 27 in ward and unclutching the wheel 184 from the wheel 28. This mechanism is already known and is merely given as an example of v a suitable unclutchin means. The upper edge of each side of .t e cam carria e 11 is provided with a bearing '30'adapte to receive the lower'end of an arm or tine 31 of a bifurcated push rod 32 whose upper end is guided in a stationary bar 33. The arms 31 are maintained in en agement with the bearings (into which t ey are inserted in a lateral direction) by the cam 12, which 'prevents any lateral motion of the said arms and is adapted to rotate between them. Overlying the upper end of each of the push rods 32 is an arm 34 offset from and suitably integral 'with (as shown in Fig. 12) a catch 35 pivoted on av rod .36 and which normally ls retained byra spring 37 in the positionin which it is shown in Fig. 1, the .said spring, at its respectively opposite ends, rbeingattached-to the arm '34 and to a stati'onary hook 37. Each of the arms 34 extends alongside ofthe forward end of a lever 38 there being provided one such lever for each of the magazines. 8 The forward 65 25iis :free to be raisedand lowered by'the jre- 'end ofthe. lever 38 is moreover provided with a hump 39. for a purpose hereinafter explained, and its extremity is beveled or inclined soas, during its'descent, to press forward the catch, 35 until said inclinedexa. lever '40 perpendicular thereto, see Fig. 2, this last named lever being operatively connected, through a link. 41, with onearm of a bell-crank lever 42. pivoted to one'side of the respective magazine 101' 2, etc., and whose other arm is, by a link 43, operatively connectedto the lower arm of a lever 44. To the upper arm. of thelever 44 there is at tached a spring. 45 which acts thereon antagonistically to the appropriate cam 12, and the said lever'is fa'st to one of the trunnions of a 'bar 16 which. latter extends throughout the whole widthof the mouth of the magazine and is free to be turned-in bearings on the said magazine, to two different positions; in one of these two positions,

as shown in connection with the four lowest down in front of 'the magazine mouth and holds back the matrices 47 in the magazine, as shown in dotted lines in Fig. 1, so as to relieve the escapement pawlsof their weight, while, in the other of-.- such positions, as shown in Fig. 1 in connection with the fifth magazine from the bottom, it presents no' obstruction to; the outward passage of the matrices.

- From the foregoing description it will be understood that when one of the cam carriages 11' is raised, the corresponding catch will be disengaged from the respective lever 38 and the front end of the latter will also'be raised under the influence of the respective spring. 45, with the result that the corresponding bar 46 willbe turned from its obstructive to its unobstructive position, in which latter position it will be retained by the-said respective spring 45, until, as hereinafter described, it is next positively turned into its obstructive" position.

The shaft 13- has rigidly secured thereto, .a key or feather -48 whereover. there is slidable a clutch sleeve 49 havingteeth 50 with inclined. faces as-shown in Figs. 2-andz4, these teeth beingcapable of engagement with similar but oppositely-inclined teeth 51 on the left-hand side of a cam disk 52 having clutch s eeve-49 is provided with a springpressed plunger. 54 as shown in dotted lines m1 Fig.- 4, the inner-end; of which is adapted to engage with a recess in the shaft 13, so as.

This 81) cam disk is, in a rotative sense, free of the shaft 13,. whereon it-is secured against axial movement by a screw 58 which, as shown-in dottedtlines in Fi 2, engages with an annular groove forms in the said shaft 13. The 35 cam disk 52. is Wei hted, as by the block or weight 59, Fig. 4, ast to it, so as to insure that when itis n its normal position, the rear or that face of the cam 57 shall be situated in a radial plane slightly in advance of the radial plane containing the forward or leadin face of; the cam 56.

lVith the before mentioned cam groove 53 there engages a-bowl 6O pivoted on a rod 61' whose lower end, as shown best in Fig. 1, is formedawith a. loop, by which it is guided on the shaft 13, and whose upper end is piv- .OtediO an arm 62 operatively fast to a bar '63 preferably of the,c1 'os s-section shown 111 Fig. 1, and to which arm thereis also. attached. one end of a tension spring 64, whose other endis attached to aconvenient part of the machine frame. Atits ends the bar 63 is provided with trunnions 65,0ne of which is shown in Fig.2, and by which it is pivoted in suit-able stationary bearings so that the rear edge of the said barv is free to V The bar 63 ov.er-

and serves, when lowered, to press on the 1-10 hump 39 of the particular one of such levers which htpd last previously been moved (as shown in dotted lines in Fig. 1) .to-bring the respective magazine 1 or 2, etc, into operative condition and thus depress the forward 11.5

'endof the said lever and thereby serving to restore the said magazine to its normal inoperative condition, that is to say, with its mouth'obstructed by the cori'es ending bar 46; during this operation the ront end of the descending lever 38, forces forward the respective catch 35 until the nose of such front end has passed the hook of the 'catch, at which juncture the said hook. is moved rearward over the lever by the appropriate spring 37. I v p g The before described collar 55 1S provided withtwo diametrically. opposite studs. 66 by which it is. pivoted in the forked and substantially vertical. arm of. a bell crank lever 0 v 67 to whose other arm is pivoted the upper end of a link 68 whose lower end is pivoted to a horizontal bar 69. The horizontal bar 69 extends beneath all of the font keys 6 and is maintained constantly horizontal by two radius links 70 which, at their upper.

ends, are pivoted to it, and at their lower ends, are pivoted to the machine frame.

The before mentioned rod 61 is prevented from moving laterally on one side by the cam 52, and on the other side, by the adjacent portion of a frame 71, the saidrod being free to move vertically-j between these two parts in respons'eto the action of the cam'groove 53 on the bowl'60. At the and engages with a. stud 76 which projects through a slot in the knife block 77 andconnects with a plunger 7 8; which is free to slide forward and backward in a-recess in the said knife block. The rear end 'of the plunger 7 8 is chisel pointed and adapted to engage with serrations or rack-teeth 79 in the front face of a wedge 80 such engagement-being brought about by a spring 81 which, as

shown in dotted lines in Fig. 1, bears on the front end of the plunger: .The upper and lower wedge-facesof the wedge 80 (which faces do not appear in the accompanying drawings but are already well known in the art) abut against screws 82 adjustable in lugs fast to the knife block 77, and the flat face of the said wedge bears against the trimming knife 83 which. is constantly pressed outwar'd against the said face by s rings 84.. The trimming knife 83 is reslliently held to the back of the knife block 77 by means of two springs 85, only one of which is shown in the accompanying drawings, and that in dotted lines in Fig. 1, and the relatively fixed trimming knife 86, Fig. 7, is, as ordinarily, secured to the vise frame 87.

The before-described arrangement of the parts 76, 78, 79, 80, 81, 82, 83, 84, 85 and 86 1s already well known in the art and therefore needs no more detailed illustration. or-

e zplanation than that herein previously given, but whereas in the existing arrangementsthe wedge 80 has been raised and lowered by hand, the present invention provides for the said wedge being adjusted auto-.

inatically. For this purpose the wedge 80 is provided with a toothed'rack 88 above the serrations 79, with which engages a spur wheel 89 pivoted on a stud 90 fast to the knife block 77, and to which wheel 89 a toothed pinion 91 is secured. The pinion 91 is in gear with a rack 92 fast to a slide 93 which is slotted to allow it to travel backward and forward on the stud 90, this slide having attached to it one end of a spring 94 the other end of which is attached to a stud fast tot-he knife block 77, this spring serving to move the slide 93 rearward and through it and the toothed gearing 92, 91, 89

and 88 to move the wedge 80 upward. This upward movement of the'wedge 80 is limited by a stop 95 fast to the knife block 77, the said stop being so situated that when the upper end of the wedge is in contact therewith, the adjustable knife 83 will be at its'maximum distance from the'knife 86. The rear end of the slide 93 (which latter, for convenience of manufacture, is con structed in two parts) is provided with an adjustable screw 96 which, by a lock-nut, is capable of being rigidly secured in any desired position of adjustment in the said slide, and at this same end, the slide is guided in its horizontal motion by a pin 97 Fig. 7, fast to the knife block 77, and which engages, with-a nice sliding fit, with a. hole in the slide.

Inuthe rim of the mold wheel 18 just to the outside .of each of; the molds 19, 19, 19",

etc;,"there is formed a recess 98, 98, 98", 98,

98 or- 98*, see 'Fi 5, in which is secured a block 99 preferab y of steel, the operative or front faces of the several blocks varying as regards. their relative distances from the front surface of the mold wheel rim, this last named result being attained by either having all the recesses of the same depth" and the blocks 99 of varying thickness, or

the recesses of varying depth and the blocks of uniform thickness. So far as this invention is concerned, the varying distances at which the front faces of theseveral blocks 99. are situated to the rear of the front surface of the mold wheel rim, are considered as the depths of the several recesses 98, 98, etc., and thesedepths vary in a certain definite relationship to the different body dimensions of the respective molds 19, 19", 19", etc.,thus,.assuming the body dimensions of the several molds 19, 19*, 19", 19, 19 and 19 mention, then the depth of the several recesses 98, 98, 98 98, 98 and 98 will sucline of matrices, each of these recesses 100,

for this-purpose, being separated from one of the recesses 98, 98, etc., by an angle of ninety degrees, and all being deep enough to .to successively increase intheir order of 94-15884; V i i different :body dimension and consequently a readjustment, of' the trimming knives, the operation of the before-described apparatus. will be,as.follows:'The depression of the. said fontltke 6, causes acorresponding de. pression oft ebar 69 which, through the link .68,-bell-crank lever 67 and clutch 49,50, 51,

causes the-cam disk 52 to rotate in the direc tion indicated by the arrow in Fig, 1, with" the result that the-rod 61 is drawn down, This lowering of-the rod .61 depresses the rear edge'of. the bar 63 and through. it, the front end of the particular 1eve'r38 which niagazinemoving from its unobstructive, to

its Obstructive position, whereiniit flpilsh es;

also effects the raising of the horizontal bar 69 .illtO its normal position. The depression of the aforesaid font keyv 6, also, through.

the link 8 and bent lever 9 connected therewith, raises the corresponding tumbler 10 and thereby withdrawsflthe support of the latter from the correspondingcam carriage 11 which thereupon descends so as to-bring its cam 12 into frictional contact with the rod. 20, lever 21 and-wedge 2-5, and other} operatively connected parts, theimoid wheelis, in known manner, oausedto present mane,

The last-named disen castingposition a mold of the desired body dimension.

By the descent as aforesaid, of the rod 61, and through the arm 72, link 73, bell-fcrank lever 74 and forked push rod, the .plunger 78- is pushed forward out of'engagement with-the teeth- 79- of the wedge 80, which thereupon, under the-influence of'the spring 94, acting through the slide 93, rack 92, pinion 91,- spur wheel 89, and rack 88, is moved to its-highestposition against the stop 95. The wedge 80 being thus raised,

allows the adjustable trimming knife 83 to be.-,move d by the springs 84 to its farthest position away from. the companion trimming, knife 86, and upon the-next ascent of the .rod'61, the plunger 78, under the influence of its spring 81, will engage the teeth 79 and-temporarily support the wedge 80 in its highest position; Q

When, after the foregoing adjustments, the ,mold wheel 18 is: moved forward to bring the'particular preselected mold 19, 19", or 19 etc., into metal tight contact with the. assembled. line of -matrices, (the proper relative position of .the-mold .wheel being secured as ordinarily by the cooperation of the usual registering pegs and sockets) one of the recesses 100 passes over the rear end .of the screw'96', without in any way affecting, it. Afterthe casting has been effected and'the mold wheel- 18 has'been retracted and makes. theusual three-quarters of a rotation to the ejecting position, and is again advan'cedto effect, as ordinarily, the necessary cooperati'on of the registering pegs and sockets, the rear end of the screw 96 is received in .a;..pre-selected one "of the recesses 98, 98 ,01 98, etc., the effective depth of I which recess is such as may either have no effect upon thesaid screw, as when the l1notype to be trimmed is of the maximum body dimension provided for-by the machine, the.

particular recess 98, 98, or 98", etc., which, for that operation is caused to receive the rear end' of the screw 96, 1s deep enough to insure the wedge SO-remainingin, or not being moved lower than, the elevated position necessary for attaining that result, the depth of the other recesses will be more and more reduc'edLa-s the body dimension of'the linotypes to be trimmed becomes less, so that for the trimming. of linotypesof minimum bod dimension it would be the shallowest oftlierecesses 98, 98,'etc., which would engage with the screw96 and move the wedge 80 to its lowest operative position, the

plunger 8 being forced against the action-1 9' of the spring 81 as the teeth of the rack-79 are successively moved downward pastits rear end.

In the arrangement represented in Figs.

8, 9, and of the accompanying drawings,

which is similar .to thatbefore described except in the features hereinafter particularized, a single adjustable mold is used, this mold having a body portion or base 101 10 rigidly secured to the mold Wheel 18, and a cap or cover 102 readily adjustable nearer to, and farther from the body 101. For this latter purpose the mold cap 102 is provided on its under or inner side with two tabs 103, by which it is guided in slots or grooves 104 in the mold body-101, while, on itsouter side, it is provided with two inclined or wedge surfaces 105, with which engage two corresponding wedge surfaces 106 on a slid- .20 able wedge bar 107. Two springs 108 exert a constant tendency to move the cap .102 away from the mold body '101, themovement in this direction being limited by the wedge bar 107. The wedge bar 107 is held to the mold wheel 18 by two guides 109 which admit of its being moved independently of the mold wheel in only fa direction parallel with the direction of thelength of the mold slot 110. At one end of the moldcap'102 there is provided a' lug 111 perforated to serve asa guide fora pin 112 which isfast tothe adjacent end of the wedge bar 107. This pin 112 is encircled by a spring 113 which exerts a constant tendencyto move the wedge bar 107 in the directionit is 'upward in Fig. 9which allows the mold cap- 102 to be moved away from the mold body 101 by'the sprin 's 108. On the front face of the wedge bar 10 there is provided a series of preferably as many steps 114 as there are changes required to be made ,in the body dimensionof the mold, and these steps are adapted to engage with the screw 96 of the knife-adjusting mechanism in the same manner as are the several blocks 99, the front faces of the several steps 114 beingfin eflect, the equivalent of the corresponding faces of the -blocks 99, the treads or-vertical-faces of the said steps being situated in relatively difierentvertical planes as are the corresponding faces of the respective blocks 99.- On the backof the Wedge bar 107 there is provided a serrated toothed r'a-ck 115 with which a detent- 116 is pressed into engagement by a spring 117 as shown in Fi 10. The detent 116 is pivoted to lugs 118 ast to the mold wheel 18, and is provided witha tail '11 9 which, when the.

mold is in its normal or ejecting position (in which it is shown in Figs. 8 and 9)is located just in front of anupstanding arm 120 fast to the push r0d .75 which, through a plunger78, serves to release a wedge 80 as and for the purpose hereinbefore described in connection with theexample illustrated in Figs. 1 to 7 and the push rod receives its motion through devices identical with those'previously described. I

Each of the cam carriages 11 of the example under review, is provided with a forwardly-extending arm, 11 to the front'end of which is pivoted the upper end of a verti- "a stationarypivot 127 ,and a spring 128, acting on this combination 'of levers, tends always to maintain it in, or return it to, the position in which itis shown in Fig. 9. The left-hand end of the lever 126 isforme'd as a guide 129 in which a bar orslide 130 is capable of moving in a longitudinal direction from the position in which it is shown in full lines in Fig. 9, to that in which, in the same figure, itisshown-in dot-and-dash lines, and vice versa, these motions being imparted to it through a lever 131 with which it is operatively connected through a pin 132, fast to the slide 130, engaging with a fork 133 on the upper end of the said lever.- The lever 131 1s free to rock upon a stationary pivot 134 and, through a link 135, is operatively connected with an arm 136 operatively fast to the left-most of the two before-described radius links 70.

The before-described vertical rods 121 not onthe-right-hand end of the lever 123 at diiierent distances from the fulcrum 124,

and, as they all receive the same length of vertical. motion, the amplitude of angular motion of the lever 123 varies according to which particular rod is operated, the leftmost and rightmost of the rods 121 rocking the lever 123 through respectively the long est'and the shortest arcs. i

The font keys 6 are of the examples shown in Figs. 8, 9, and 10 are each 'rovidedpreferably witha handle 137 in p ace of the finger pad shown'in Fig. 1, this, for enabling the operator more conveniently to apply the increased power necessitated by the addi- 1 15 tional loadf imposed by the working of the slide 130'.

The mold wheel 18 of Figs. 8 and 9 having only one mold, is operated in ractically the same manner as the corresponding wheel of an ordinary'linotype machine, that is to say it receives an angular motion of first-90 degreesfrom what is known as the ejecting or ,normal position (which is that repre sented in Fig. 9) to the casting position, and

then a; further angular motion of 270 de-- grees onward to the ejecting position; it also receives motion in a fore-and-aft direction as ordinarily, but that has no bearing on the present invention, i8 9 is so wedge 80, as in the example illustrated in- Figs. 1 to 7 the upstanding arm 120, fast to the said push red, by acting on the tail 119 of the detent 11G, disengages the latter from the toothed rack 115 and thereby allows the wedge bar 107 to be raised by its sp'rin 113, into its highest position, and the molt cap 102 to be moved by the springs .108 toits maximum distance away from the mold body 101. Upon the return movement' of the push rod 75, that is to say, in a direction rightward of Fig. 8, the detent 116, under the influence of its spring 1177, is again engaged with the rack 115.

The act of depressing the .font keyG as 'bar (39, and this ogeration, through the lever arm 13G, link 135, forked lever 131, 133, and.

pin 132, also eflects the movement 'of the shown in full-lines in Fig. 9 to that in which it is represented in dot-and-dash lines in that figure, in which latter position it overlies the'top of the Wedge bar 107.

It will be remembered-in connection with the apparatus illustrated in Figs. 1 to 7, that each of the cam carriages 11 is rocked on its pivot to effect the operative substitution of one magazine for another; in the example illustrated in Figs. 8, 9, and 10 this rocking movement of the cam carriage is utilized for adjusting the mold to suit the various body dimensions called for by changes of font resulting from the said magazinesubstitution; For this purpose 40 the vertical rod 121 pivoted to the particular cam carriage which is rocked, is caused to depress the proximate end of the 'lever 123, and, as a consequencethereof, (through the lever 126 and slide 130) to depress the wedge bar 107,- the teeth of the rack 115 meanwhile slip in past the detent' 116.

The extent of tlie epression of the wedge bar 107 varies according to which particular one ofthe rods 121 is depressed as before so explained, and consequently the mold cap 102 is caused toapproach the mold body- 101, also to a varying extent, to correspondingly vary the body dimension of the mold slot 110, the detent 116, by engagin with the rack 115 at the termination of t e descent of the wedge bar 107, servin to retain the latter in ad usted position. en the font key .is released and the horizontal bar 69, aspreviously described, is caused to return to its normal elevated position, the slide 130 is withdrawn from over the wedge bar 107, by means of the forked lever 131, 133, link 135, and lever arm 136.

It {will be observed that, as all theforego: ing adjustments depend for their coming just mentioned, also depresses the horizontal v slide 130 from the position in which it is into effect upon the depression of one of the font keys 6, the machine will remain in the same operative condition of adjustment until later,"a'nother of the said keys is de pressed. 1 l

The before-described automatic knife adjusting mechanism, instead of being incorporated in a typographical machine provided with both a magazine selection apparatus and a mold selection apparatus, as in the example illustrated in Figs. 1 to 7 of the accompanying drawings, or a magazine Selection apparatus and mold adjusting mechanism as shown in Figs. 8, 9 and 10 of the said drawings, .can be incorporated in a go typographical machine provided with the magazine selection apparatus independently of mold selection or adjusting mechanism. One obvious way of attaining the last-named result would be to substitute an ordinary mold for the adjustable one shown in Fig. 9', and a parallel-sided bar, for the wedge bar 10Tshown in that figure, the said bar being suitably guided on thew mold cap or mold carrier, and being in all other respects constructed and operated precisely as in the wedge bar hereinbefore described, and, so far as its knife-adjusting properties are concerned, fulfilling precisely the same functions.
