To all whom, it may concern,.-

Be it known that I, WALTER JAY ENNissoN, a citizen ofthe United States, residing at the -city of New York, county of Kings, and State of New York, have invented certain new and useful Im rovements in Type-Justifying Machines, fu ly described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to justifying mechanism, the especial object being to provide an improved mechanism for measuring unjustified lines of type and ascertaining in accordance with the measurement ofthe lines and the number of word-spaces therein the thickness of the individual spaces required to justify the lines measured. A

The invention' includes also im roved means for handling and controlling t e line of type in process of'justification, for inserting space-markers or temporary spaces or word-separators, for substituting the permanent justifying-spaces for the temporary spaces or word-separators, and means for returning the temporary spaces to their magazine.

l The general' features of the mechanism illustrated herein as embodying the invention are as follows: yfirst, ak proportional measurin device for ascertaining the required tlnckness of justifying-spaces, which com rises a line-measuring device, a dividing mec anism composed of a series' of gear sets or trains, with adjustable means for selecting the particular set thereof corresponding to the number of word-spaces in the line to be means for o enin justified, and a gage set b action of said devices to determine the t ickness of spaces required to justify the line measured; second, type-driving means for conducting the unjustified line of type Within and through the machine, consisting of a circular typeway and a type-engaging arm adapted to swing concentrically with the curve of saidtype-l way, which arm constitutes apart of the measuring mechanism of the justifier; third,

the line between' the several words t iereo for the insertion of permanent justifying-spaces, including means for removing the temporary spaces composed with the unjustified line and returning the same to a magazineprovided therefor, and, fourth, the parts employed .in actuating the` various mechanisms of the machine, consisting of constantly-moving shafts, with sleeves thereon upon which are grouped the cams and actuating parts of the word mechanisms and line mechanisms of the machine, and means for-operably connecting the sleeves to the shafts as required.

For a full understanding of the invention a detailed descri tion of thea-mechanism embodying the a ove general features anda modification thereof will now be given in the features forming the invention will then be specifically pointed out in;,the claims.

These three views taken together show successive stages in theoperation of the gearjustifying mechanism-the clutch-operating mechanism and other parts of the machine. Fig. 7 is an enlarged :sectional view taken on the line 7 of Figs. 1 and 3. Figs. 8 to 14, inelusive, are detailed views of the mechanism employed in separating the line for the reception of justifying-spaces and for removing the temporary separators therefrom. Figs. 15 and 16`are detail views of the word-key mechanism, shown in two positions. Fig. 1,7 is a detail of part of Fig. 4. Fig. 18 is a detail plan view of a modified form of dividing mechanism.

will first describe in detail the mechanism employed in ascertaining the size or thickness of the space or spaces required to justify .the line of type, which mechanism com rises several inde endent devices, which wi l'be given in the fo lowing order: first, those parts employed in measuring the unjustified lineof type to ascertain its aggregate shortage, next the means by which that ascertained vg shortage is divided in proportion tothe-numcoiiiiegtion with tbe accompanying ings, forming a part ofthis specification, and

ber of spacesin a line to be justified, and then the means whereby the dividing mechanism is set in accordance with the number of wordspaces in the line to be justified. The meas uring and dividing means and the parts pertaining thereto having been described, the mechanism for advancing the line to the devices employed in separating the words for inserting justifying-spaces will be described, together with these devices. Then, finally, the various driving and actuating parts of the justifier will be described.

In the machine illustrated the unjustified line of'type x is played into the justifier from a type-setting machine, in which it is coinosed, with temporary spaces or separators The separators a emloyed are preferably of the form shown, havpointwise width of the type with which the sanie are composed but of a thickness of the irinimum sizrof .41X- tending from either end is a pivot-like proj ection which, as the separators are composed with the line, extend both above and below the lineltype, the bottom of the type-clianiiel having a longitudinal groove to admit of the projection of the separators.

The stick or line-cliannel 40 is a circular typeway adapted to hold the individual type composing the line each in a vertical osition, at the center of the curve of which is the vertical type-driving shaft 41, upon whose upper end is fixed the type-d riving arm 42, which is provided with a type-engaging s jaw 43, preferably a spring-pressed pawl, as shown. The type are carried into the channel of the typeway 40 by the conposing-iiachine, which nay use any suitable devices to justifier mechanism to remove the preceding line longer than the time necessary for the spring 45, attached to pawl 43 to cause that pawl to snap into its position to engage the line, which is practically instantaneous. The type-engaging projection of the pawl 43 presents a square type-engaging surface 1 both forward and back, the forward surface coning into use when pressing the line forward, the rear surface being then in position to be enga-ged by a new line, which may be plaved into the justifier before the type-driving arm has had time to move forward out of the way of the new line thus forir ing. For this purpose it has been provided that when the machine stands normally at rest the shaft 41 and its type-driving arm 42 are 'free to be carried forward, in case they be engaged by the new incon ing linehthe type-driving pawl 43 and its shaft 41 standing normallyT at a point back of its theoretical zero line ireasuriiig position and not at the position from which the pawl would move irerely to ascertain the shortage of an unjustified line.

Upon the outer wall of the circular channel 40 and extending radially therefrom is a i bracket 51, in which is suitably constructed a assemble the line at a point in advance of the 1 withdrawing the same 11i proper timing with awl 43 in its rear or normal position. As

illustrated, the type are advanced by the 1: composing-machine to the swinging sweep or i,

ity cf which is an arm 54, the swinging end of normally out of the path of the type by means of a second pawl or detent 44, also car.- ried by the type-driving arm 42, against one fork of which pawl 44 a proj ectiiig arm or pawl 43 is held by neans of a spiral spring 45, suitably attached thereto. A slight outward turn of said detent 44 will give the type-driving pawl 43 perfect freedom to be carried by its spring 45 into engaging relation with the type in the typeway. Means for thus turning the detent 44 consist of a bell-crank lever 46, suitably mounted upon a fixed part of the justifier, to one arm of which is attached the link 48, which in turn, by rreans of a pin projecting therefrom about nidway of its length., is adapted to bedepressed by a lever 49 and linekey 50. It will be seen later on that by depressing the line-key 50 the line-advancing mechanism will be set in motion, and by reaguideway for a slide 52, said slide being adapted to be interposed across the channel cf said typeway, thereby furnishing a rigid stop ci' abutment in the path ef the advancing line. Means are provided fer interpusing said abutment across the channel-way and the operations of the machine, consisting of the vertical shaft 53, upon the upper extremf which enters a slot provided fcr the purpose The pawl 43 is held within said abutment 52. Means fcr rocking said shaft 53 to alternately insert and withdraw said abutment is supplied by a cam 55 upon the werd-shaft 56 and an arm 57 upon the typeedriving shaft 41.

The pawl 43 on the type-driving arm 42 and the sliding abutiizeiit 52 constitute the measuring-jaws between which the unjustified line of type is calipered in the process of measuring the aggregate shortage thereof; tliat' is, ascertaining the total width of the spaces that will'be required in bringing the line up to its standard length. The pawl 43 may be called a "movable measuring-jaw and is actuated by fricticiial yielding means, consisting of a sliding friction-clutch 60, splined upon the type-driving shaft 41 and adapted to be alternately thrown into and cut of contact with the concave surface cf a constantly-moving gear 61, also loosely IOO IIO

ISO

mounted upon said shaft 41. Means are employed to complete the measuring operation in connection with calipering the line between the two measuring-jaws and to transmit the result thereof to the dividing or space determining mechanism, this means comprising the gear-segment 62, loosely mounted upon said shaft 41 immediately beneath the arm 42 and resting upon the upper bracket 63 of the shaft 41. (See Figs. 1 and 2.) Uponl the hub of this gear-segment 62 is the short arm 64, whose outer end is adapted to engage the hooked end of a connecting-de tent 65, (see Fig. 1,) pivoted to the under surface of the type-driving arm 42, which carries the pawl or movablemeasuringjaw 43. Adjacent to and parallel with the shaft 41 is a shaft 67 tothe extreme upper end of which is secured a pinion 68, which meshes with the gear-segment 62 and is adapted to be rotated by the segment. Upon the shaft 67 is provided also a sliding friction-clutch 69, adapted to engage a corresponding concave frictional surface in the hub of a constatly-moving gear 71, loosely mounted upon the shaft 67 in a manner similar to the gear 61 on shaft 41.. Thus it will be seen that if the type-engaging surface 1 of the pawl 43 stands normally at a point in the typeway 40 removed from the type-engaging surface of the stationar measuring-jaw 52 a distance equal to the ength cf a standard line said pawl in fetching up against the line on its rotation from normal position will have traveled in its circumferential path an amount or the number of degrees representing the aggregate shortage of the unjustified line, and the shaft 41, with which said arm 42 revolves, will have been rotated an equal number of degrees. As explained above, the normal position of the pawl 43 is not at the theoretical zero position-that is, the length of a standard line from the abutment 42-but somewhat behind such zero position; but this is allowed for in the construction of the machine, and the measurement is the same as though the arm started at such zero position. To actuate the shaft 67 according to this measuring movement, the projecting arm 64 of gear-segment 62, which revolves upon the same center as the arm 42 bearing the movable measuring-jaw-43, is made to move until the arm 64 strikes the pawl 65, when the arm is stopped, and thus the pinion 63 in mesh with the segmental arm 62 will cause the shaft 67 upon which it is secured, to move in fixed ratio to the movement of the segment 62, so as to move proportionally to the shortage of the line which has determined the position of the stop-pawl 65. On the return of the shaft 41 and arm 42 the pawl 65 returns the segment 62 by engagement with the forward side of the arm 64 and then rides up on the arm 64 to the position shown in Fig. 1.

I will now describe the means employed for dividing the shortage shown by the measurement above described.

Upon the shaft 67, which it has been seen is made to rotate an amount directly proportional to the aggregate shortage of the line, is a series of gears 75, loosely mounted thereon, increasing in diameter from top to bottom, the same being arranged in a form similar to that of a cone whose axis will coincide with that of the shaft 67. Parallel with said shaft 67 is the registenshaft 76, upon which is a second series of gears 77, (shown as segments of the required lengths,) arranged in similar conical form, but in the inverse order to those on the shaft 67, so that the apex thereof points in the opposite direction to the other cone. These gears are arranged in pairs meshed together, one gear of each Pair being loosely mounted upon the measurer-shaft 67, the other gear of the pair being secured to the register-shaft 76, means being provided, as hereafter described, for securing any one of the gears to the shaft 41, so as to rotate therewith in measuring the line. The relative diameters of thegears constituting each pair is such as to cause the register-shaft 76 to rotate in a required fixed ratio to that of the other shaft 67. The relative diameters of these gear sets differ by fixed amounts in such manner that if the first pair (or bottom pair in the machine illustrated) should operate to cause the register-shaft to rotate an equal amount to that of the measurer-shaft the next upper pair would operate to rotate the register-shaft an amount one half that of the measurer-shaft, while the third, fourth, fifth, and succeeding pairs of gears would similarly cause the register-shaft to rotate, respec tively, a third, fourth, fifth, or other correspondingly proportionate amount. lt will be seen that the gears thus arranged in progressive pairs are adequately adapted to provide means for dividing the ascertained line shortage according to the number of word-spaces to be supplied. Each set or pair of gears is employed only in the justification of lines having a given number of Word-spaces, and hence as many pairs are required as the largest number of word-spaces possible to occur in the lines to be justified therein. The present device is adapted to IOO handle lines of twenty or less words or having itios, respectively; but in a machine employing ready-made or foundry spaces, to be selected from among fixed sizes, it is desirable to have the gaging mechanism move in multiplied ratios. In the present form of my invention I have madel the relative diameters of the gears as of a machine of the last-named variety, which are designed to transmit a multiplied divided movement to the gage mechanism wherein the divided result is in each instance multiplied by a fixed or constant factor, the number 7 being used in the machine shownthat is to say, the first set of gears used in one-space lines instead of being of equal diameters are given diameters in the ratio of seven to one, so that the register-shaft is made to rotate through seven times as many de rees as does the measurershaft, and, similar y, the second pair for twospace lines instead of causing the registershaft to rotate one-half as much as the measurer shaft in the machine shown drives the register-shaft three and one-half times as far as the measurer-shaft. Likewise the third pair instead of giving a division of one-third rotation for the register-shaft would rotate it two and one-third times as far; the fourth pair one and three-fourths times instead of one-fourth, and so ou throughout the series.

The means provided for conveniently selecting the proper pair of gears to correspond with the word-spaces to be used consists of a sliding key2, fitted into a longitudinal groove 3 in the shaft 67, upon the lower portion of which is a ratchet 4 of nineteen teeth corresponding in pitch to the thickness of the single gears upon the shaft 67. At the extreme upper portion of the slid ing key 2 is the keyproper, 5,which engages suitable keyways cut in the gears 75. 'Ihe key 5 is of a length slightly less than the thickness of an individual'gear, so that it will secure to the shaft 67 only one of the gears 75 at a single operation. A spring-pressed pawl 6 is pivoted upon a slide 78 and is adapte-d to engage with the teeth of the ratchet 4, the slide 7S being mounted upon the shaft 67 and adapted to slide thereupon in order to carry the key 5 to whichever gear 75 may be required in the justification of the line. The means employed for determining the particular tooth in the ratchet 4 of the sliding key 2 into which said pawl 6 shall enter consists of a slide 7, provided with a fiange 8, forming a fender and corresponding in length to the ratchet 4 of the key 2 and adapted to engage a pin 9 in the tail of the pawl 6 and hold the pawl out of the rack 4. Upon the slide 7 is a ratchet 10, whose teeth are the same in number and pitch as those of the ratchet 4, into which ratchet 10 a detent 11 is adapted to engage, holding the same against the action of a spiral spring 12 into whatever position the -slide may be depressed, The slide 7 moves in suitable bearings 13 in a path parallel to the key 2 of the shaft 67 and is so disposed that the ange 8, by pressing against the pin 9 of the pawl 6, will hold the pawl out of engagement with the ratchet 4 of the sliding key 2 for the whole or a part of the distance of the travel of the ratchet 4, by means of which, in accordance with the extent to which said slide 7 has been depressed, the pawl 6 may be made to drop into the particular tooth desired of the ratchet of the sliding key 2.

In a simple form of construction of the ses mechanism now under consideration the slide or rack 7 might be connected directly with the word-key 20 and form the settingrack, so that the operator on coming to the end of each word where a space is required would move the slide 7 andfender 8 to a corresponding position for setting the machine in accordance with the number of separators inserted, in which case the operator would necessarily be delayed the length of time required for the mechanism to get under way before starting a new line, as the mechanism actuated by the space-key might not be released in time for the next line. In the mechanism shown, however, a supplemental setting-rack 15 is provided to slide longitudinally in the direction of the fender-slide 7 and is provided with aratchet 16, whose teeth correspond in number and pitch to those of the slide 7 and likewise to those' of the ratchet 4 ofthe sliding key 2. of the pawl 17, which is actuated each time a word-separator is inserted into the line to be justified, the rack 15 is moved a distance equal to the pitch of its teeth, in which position it is held by a detent 18. (See Fig. 4.) A pin 19, projecting from the side of thc slide 7, carrying the ilange 8, is engaged by the lower edge of the setting-rack 15, which when moved down by the pawl 17 positions the lange S to hold the pawl 6 out of engagement with the ratchet 4 of the sliding key 2. Thus it will be seen that by forcing` the rack 15 down a given number of teeth the fenderslide 7 is thereby depressed a like number. of teeth, which in turn will operate as described upon the key-driving pawl 6 to hold it out of engagement with the teeth of the rack 4 of the sliding key 2 until that tooth is reached which corresponds to the given number through which said setting-rack has been depressed in the manner described.

Means for actuating the pawl 17 may be conveniently supplied by connecting the same directly with the word-space key 20 in order that the rack 15 may be moved a distance of one tooth for each word-space in the line to be justified. In my present mechanism the same end is attained by connecting the actuating means of said pawl to the mechanism which inserts the temporary word-separators, so that when a separator is inserted the rack 15 will automatically be moved the distance of one tooth for each By means IOO separator inserted. The mechanism employed for inserting these separators and the connections between this mechanism and the setting-rack 15 will now be described, first describing briefly the reservoir for storing the separators.

A collapsible magaziiie-channel 22 (see Figs. land 7) contains the separators c, which channel is adapted to hold a varying length of line of separators arranged vertically side to side, the channel being approximately the pointwise width of the type which the justiner is adapted to operate upon. Une portion of said magazine is a sliding block 23, provided with a semicircular channel-groove 24 and projections 25, which slide in grooves 26, formed in the walls of the channel 22, against the action of the spring 26 to lengthen the channel when a separator is forced into the line contained therein. Likewise when a separatorV is withdrawn the spring 26 will draw the block toward the channels into which the same is iitted to slide, operating thus to shorten the channel length, keeping the channel 22 always of the exact length required to accommodate the separators therein. One end of this separator-channel is in convenient proximity to that portion of the justifier-typeway 40 in which the characters are assembled, and means are provided for ejecting the separators therefrom into the typeway 40 while the line 'is being composed. 'lhe opposite end of the4 channel 22 is similarly placed near the typeway 40 in convenient position to receive the separators as they are ejected from. the line by the action of the word-slide, which will be more fully explained hereinafter.

'lhe means for ej ecting the separators from the reservoir into the typeway extension consists of a horizontal slide 28, which is held normally in a position wherein its ej ecting-f ace 29 coincides with the adjacent inner channelwall of the typeway 40 and whose side furnishes an abutment against which the separators in the collapsible channel 22 are nrmly compressed by means of spring 26 in the manner described. Any convenient means may be employed in connection with the composing-machine for moving the slide 28 back from its normal position surllciently to allow the line of separators in the channel 22 to push the foremost separator therein into the space previously occupied by the ejectorslide 28, s', that such actuating means being withdrawn the ejector-spring 27 will carry the ejector forward and transfer the separatloi` from its channel into the line in which the type are being composed. ln the present machine a bar 30 (see lligs. 1, 15, 16) is pivoted to one end of a lever 31, suitably mounted upon a bracket 32, secured to the framework A of the machine, and the other end of the lever 32 is provided with a rounded'- portion which is fitted into a suitable .entering the notch g in the bar.

opening in the ejector-slide 28. Upon the outer end of this bar 30 is a spiral spring 33, adapted to hold said member against a vertical slide 34, suitably mounted in the fra-me of the machine, which is adapted to be forced 7 o downward by the word-space key 2O against the action or' a spring 35 and out of contact with the bar 30, permitting the bar 30 to be drawn to one side by its spring ,33 into position to be struck by a constantly-vibrating arm 100, which may be provided in any suitable manner, but is shown as carried by the sweep l5, which moves the type into the channel.

The arm 100 has a lug m, having a square 8o surface on one side, which on motion of the arm 100 to the right in li'ig. l engages fixed catch o on bar 3U and moves the bar to the right, where it is held by the spring-detent p,

Un the next movement of the arm to the right the lug m engages the spring-catch n on the bar 3U and moves the bar farther to the right, so

as to fully withdraw the ejector-slide 28 from the end of the separator-channel and 9o allow a separator a to be fed out into position to be moved by the ejector 29 into the typechannel in iront of the n ext type to be fed in. 'lhis insertion of the separator takes place on the return movement of the sweep and arm '9 5 100, the spring 27', which has been put under tension by the movement of the bar 30 =to the right, actuating the ejector to insert the separator after the sweep has moved beyond the ejector on its return movement, and Ico movement ol' the ejector returning the bar-30 to the left and into normal position. As shown, the catch p and notch Q are arranged so as to hold the bar 30 against the tension of spring 27 when it is put partially under ten- 1o 5 sion on the iirst movement of the bar 30, but

to yield and permit the return of bar 30 when the spring 27 is put under greater tension on the complete movement of the bar. A detent of any other suitable construction actui io ated positively by the machine or otherwise may be used in place of the detent device shown. The space -key having been released, tlie catch m on this second forward movement of the arm 100 with the sweep B. i i 5, moves the bar 30 outward against the tension of spring 33, and the bar 34, being thrown upward by the spring 35, will hold" the bar 3U in its normal position, as shown in,i Fig. l. x12o 'lhe pawl 17, employed for setting the rack 15, as has already been described, is carried upon an arm of a bell-crank lever 36, (see Figs. 4 and 7,) which is adapted to be rocked upon its pvot byfmeans of an arm 37, sonV cured to the lower end of a rock-shaft 38, which in turn has an, 1actuating-arm 39 similarly secured to its upper end, the swinging end of which actuating-arm 39 is made to enter al slotted 'projection 39, extending 13o downward from the ejector-slide 28, so that when the ejector-slide 28 is carried back in the manner described above it will cause the arm 39 to oscillate, thereby rocking the 5 shaft 38, which, with the action of the arm 37 upon the downwardly-extending arm of the bell-crank lever 36, will operate to force the pawl 17 downward, carrying with it the setting-rack 1'5. I Although no means are Shown in this application for selecting or supplying the justifying-spaces, provision is made for carrying I the unjustified line into proper position for the'in'sertion of justifying-spaces and sep- I arating the line at the points between words where temporary separators have been inserted t0 designate the proper places for iiiserting justifying-spaces.

The means employed for carrying the line 2o along the typeway 4() consists of the shaft 41, the arm 42, and pawl 43, operated thereby, which have already been described. It only remains to point out that by providing suitable means for actuating the clutch which controls the movement of the shaft 41 it may be employed to carry the line on through the typeway for the purpose of inserting the justifying spaces and removing the temporary separators. This has been accom- 3o plished in the present machine by means of the frictional clutch upon the shaft 41, which is provided with means whereby it is thrown intocontact with its driving-gear 61 by operation of a cam 80, fixed to the word- 3 5 shaft sleeve 81, mounted on the shaft 56. Upon the surface of the cam a cani-roll 82 of a bell-crank lever 83 contacts, the lever 83 being secured to a rock-shaft 84, to which is also secured the forked lever 85, (see Figs. 3

+o and 4,) that engages the friction-clutch 60 upon the type-driving shaft 41. The surface of the cam 80 is suitably constructed so that it will alternately throw the clutch 60 into engagement and release the saine upon each 45 'full rotation of the word-shaft 56, thereby intermittently moving the type driving shaft 41 and type-driving pawl 43 as may be required for the purposes of inserting the justifying-spaces into the lines and removing 5o the separators therefrom.

r1`he means provided for separating the completed forward and .return movements, where it is momentarily stopped -to perform functions incident to its operation. The word-slide comprises two parallel members 94 and 95, one directly over the other 7o and separated by a little more than the height of a character type, the bottom member thereof having its upper surface coincident with the plane of the Hoor of the typeway 40. into the opposite surfaces of the 75 members 94 95-that is, the bottom surface of member 94 and top surface of member 95- slmilar diagonal grooves or Cain-paths 96 are cut, extending at a convenient angle from one side to the other and cutting into the 8o surface of each of the members 94 and 95 to a suilieient depth and width to admit of the free passage of the pivot-like extensions a a2 of the temporary word-separators a. The word slide 90 stands normally with the 85 grooves 96 wholly without the line of the channel of said typeway 40, as shown in Figs.

8 and 9; but upon the first movement thereof the grooves will be carried across the chF-s nel, as shown in Fig. 10. In the normal po- 9o sition of slide 90 it will be seen that the two members 94 and 95 supply stops above and below the type-line which are adapted to engage the two pivot-like extensions a a2 of the word-separators a as the line containing the sameis pressed forward by the action of the type-driving arm 42 and its pawl 43, and thus stop the line. It will also be seen (see Figs. 8 and 9) that as the slide stands in its normal or stop position a bar 97, which roo forms a part of the word-slide and moves w ith bars 94 95, presents a wedge-shaped end 98 to the line that is being pressed up against the stops 94 95 of the slide 90, which end 98 as the slide nieves forward will be carried between the separator a and the adjacent fragment of the line, so as to stop the rest of theV line as the separator passes into the grooves 96, which carry the separator forward with the word in advance of it. Just iro at the entrance of the grooves 96 are inclined projections 99 on the members 94 95,

which are adapted to engage the extensions a a of the separators a and force them to v enter the cani-grooves 96 as the slide moves i i 5 line at the several points where temporary separators have been inserted preparatory to the insertion of permanent justifying- 55 spaces and i'or removing these separators from the said unjustified line is what may be termed the word-slide 90, (see Figs. 1, 4 and 8 to 14, inclusive,) which is adapted to reciprocate transversely to the channel of forward in the position sliown in Fig. 10 the line has been fully separated for theeinsertion of permanent justifying-spaces by the inclined i grooves 96, carrying forward the separator 12o 6o the t'ypeway 40 in suitable guides 91 in the frame A. '1 he word-slide 9U is operated by means or' a cam 92, secured to the word-shalt sleeve 81 through a cam-lever 93. rllie cani 92 -is so constructed that it carries the slide o5 90 into four different positions in making its l and word ahead of it. 'lhe word-shde 90, however, does not come to a stop at the position shown in Fig. 10, but moves on to the position shown in Fig. 11, in which position shoulders c on the members 94 95, behind the i 2 5 grooves 96, have carried the separator a out j of the typeway and has inserted it into the channel 22, provided for the separators.

'1 he word-slide 90 then returns immediately to its extreme opposite throw or position, as 3o Y the line.

shown in Figs. 12 and 13, in which position its port-holes 101. are brought into line with the channel of the typeway for the purpose of allowing the permanent justifying-spaces b to be carried up through the floor of the typeway into the opening that has just been made in the line, as described. Two porthiales are shown in accordance with the space system I prefer to use; but this is immaterial so far as the present invention is concerne i. Fig. 13 shows the space moving up into the line. These spaces may be inserted by any convenient means-such, for example, as that described in the Patent No. 583,224, issued to W. H. Honiss and myself. After the justifying-spaces have thus been carried into the line an extraforward movement to an extent e ualing approximately one-half the width o the spaces may be given the word-slide 90, so as to move it to the position shown in Fig. 14, in which case the iioor member thereof will act as a detent for holding the separator into the line until the eiecting means can be wholly withdrawn, whereupon the word-slide is carried a step farther into its normal position, as shown in Figs. 8 and 9. It has been seen that while the wordslide was carried forward the bar 97 serves to hold the line back while the spaces are being inserted, and when theword-slide is carrie to the opposite position, as shawn in Figs. 12, 13, and 14, the bar 97 is withirawn from the position in which it can act as a stop against the unjustified portion of the line. Therefore a projecting stop 102 is supplied carried by the Word-slide on the opposite side of typeway 40 from they bar 97,-into which stop 102 vertical grooves 103 are cut correspondin(T to the surface dimensions of the porthotles 101. 'Ihese grooves assist in guiding the spaces as they are carried upward into rIhis stop 102 furnishes a surface which supplies practically a continuation of the type-engaging surface of the bar 97 on the opposite side of the typeway and acts as a stop against the unjustified line when it is carried back into the position shown in Figs. 12 and 13. The only point at which the line of type could pass through the word-slide 90 therefore is that presented to the typeway v hen the slide.90 is in Iits normal position, as shown in Fi s. 8 and 9, and in this position e stop-sur aces of the members 94 and 95 `,resent themselves to the extensions a a2 of the separators a, and progress of the line through the word-slide is checked at this tir.. e by the foremost separator in the line.

I will now describe the driving means and the various connecting parts employed therewith in actuating the various mechanisms of the justifier.

Two shafts horizontall)T disposed in brackets 104,-extending out from either side of the frame-plate A and parallel one to the other, are connected by gears 105 106 107. (See Figs. 2 and 3.) One of these shafts 108, which I will call the Iline-shaft, carries the driving-pulley 109, to which is transmitted the initial power required to operate the machine. Upon the shaft 108 is a loosely-fitting sleeve 110, upon which are carried the several cams which are employed in the operation of those parts brought into action once only for each line justified, such as measuring the line and returning to their ncrinal condition thereafter these parts which have been directly or indirectly engaged in the operation thereof. In like manner the word-sleeve 81, previously referred to and loosely mounted upon the shaft 56, which I will designate the word-shaft, has upon it those parts called into use in removing the temporary separators and replacing the same with permanent justifying-spaces and other operations relativo 1' here to. Means for starting and stopping the word and line sleeves, respectively, at the proper times will next be treated. Upon each of said sleeves is a disk 111 112, havingr upon the faces thereof hooked clutch-pawls 113 114, which are moved by springs into position so that the hooked portion thereof will engage with a tooth (or in the case of the line-shaft 10S one of four teeth) upon wheels 1.17 11S, secured, respectively, to line-shaft 10S and word-shaft 56. Thus it will beseen, taking one of the clutchesclutch 114 of the word-shaft 56, for examplethat so long as the pawl 114 is held out of engagement with the toothed wheel 118, pinned to the constantly-moving word-shaft 56, the sleeve will not be affected. thereby, but will remain in its normal position of rest.

Means in the nature of stops are provided for engaging the outwardly-projecting radial arms of the clutch-pawls 113 114, whereby the clutch-pawls are held out of engagement with their corresponding toothed w' ieels 117 11S until the stops are again withdrawn by the means which will be described in their order.

The means by which the clutch-pawl 113 (see Figs. 4, 5, and 6) is held out of engaging relation with its toothed wheel 117, while the line-sleeve 110, to which the pawl is attached, is in its normal position of rest, consists of the stop-detent 120, suitably attached to a short shaft 121, supported by a bracket 122 upon the frame-plate A and which is adapted to be rocked sufliciently to release the hooked end of said detent 120 from the projecting radial arm of pawl 113. To actuate the shaft 121, a lever 123 is secured to said shaft, to which lever is connected the link 48, which, as previously described, is provided with the pin which is inserted through a :slot in the lever 49, to which is attached the kry-stem 50, used by the operator in starting the mechanism. rIhe st -detent 120 is held normally in engaging relation to the pawl 113 by means of a spring 124, so that upon IOO IIO

A second stop 125 (see Figs. 3, 5) in its normal position of rest is adapted to act on the line-clutch pawl 113 to throw it out of engagement and bring the line-sleeve 110 to a position of rest at approximately two-thirds of its rotation. on a slide 126, which is This stop 125 is a projection i operated from two E with the bevel-surfaces of the frictionclutches anLQ, to which reference has already been made. Friction-clutch 60 is i constructed to slide longitudinally upon its sources-one, the word mechanism, which, it l will be see-n in another connection, removes the stop 125 as the word-shaft makes its last rotation, and the other by'action of a cam projection 127 upon a cam-disk 128 on the line-sleeve 110, by action of which the arm 126 is returned to its normal position.

provided consisting of the cam projection 127 uplon the cam-dis( 128, whereby the stop W ich is holding the clutch-pawl 114 of the stopj shaft 41, being splined thereon, and in a similar manner clutch 69 is adapted to slide longi tudinally upon its shaft 67.

It has already been noted that the typedriving shaft 41 is first called into use in advancing the line in the typeway until the line meets the intervening slide or abutment 52,

wl `ch has been interposed across the channel of the typeway for the purpose of measuring the 11n-justified line contained therein, and then the friction yields until the clutch-contact is released, and that immediately followingl this the clutch mechanism on the linemeasuring shaft 67 is called into action to bring the mcasirer-arm 64 into contact with the connecting-detent rpon the typedriving arm 42. (See Figs. 1 and 2.) It is therefore desirable to have the clutch 69 on f the measurer-shaft 67 engage at the same In the rotation .of the line-shaft means are l word-shaft 56 out of engagement with its E toothed Wheel 118 is withdrawn, so that the Word-shaft sleeve 81 is caused to rotate. The g means employed for throwing the clutch-f pawl 114 out of engaging position with its toothed Wheel 118, as above described, consists of the stop-slide 126, which is adapte-d to slide longitudinally,

so that a stop 13() on l the slide 126 is drawn into the path of travel of the outward-extending arm of the clutehpawl 114. The means employed for throwing the stop 130 into the path of the pawl 114 consists of the device which I will call the fgoverning-arm 57 and which is the type-driving shaft 41 and which fixed to when the line has been justified and carried to the end of the typeway 40 strikes the upright member 131 of the slide 126, carrying the stop 13() upon the slide 126 into engaging relation with the radial arm of the clutch-paw] 114 and detaching the pawl from its toothed wheel 118.

I will now describe the mechanism for op- 5 actuating 5 other of the cams 8() 141 may be reqrired to erating the clutches employed in carrying the f line along the t eway 4U and 'in operating the measurer-shaft 67.

Upon the type-driving shaft 41 and the measurer-shaft 67 are fitted to run loosely the two gears 61 71, meshed together, one of which, the large gear 61, is secured to a sleeve 132, which is fitted to revolve loosely upon the shaft 41, and at the lower end of which sleeve 132 is the small bevel-gear 133, which is in mesh with bevel-gear 134, secured to one end of line-shaft 108, so that gears 61 and 71 are in constant motion with the lineshaft 108. In the hub of these two gears 61 and 71 are concave ockets to correspond moment that the clutch 60 of the type-driving shaft 41 releases. This timing of the ch-.tches 60 69 is accomplished by having the iever-arms which actuate the same connected with the rock-shaft 84 in such manner that when either releases the other is carried in the direction to engage.. One of said leverarms 85 connects directly with the clutch 60 of the shaft 41 by means of two pins extending from its forked arms into a groove in the periphery thereof. The other arm 136 (see Figs. 3 and 4) is connected with the shaft 84 by means of link 137 and lever 138, secured to the rock-shaft 84, the arm 136 being similarly provided with pins fitting 'to the circumferential groove of the clutch 69. The lever-arms 85 136 are actuated by means of the hell-lever 83, siLitably secured to the order end of the rock-shaft 84, to the opposite arms of which are attached the cam-rolls 82 and 140, which engage the peripheral surfaces ol' cam-wheels 8() .and 141 rponthe word and line shaft sleeves, respectively, being held against said cam-s'. rfaces by a spring 142, against the action of which one or the operate the lever 83 in order to shift the friction-clutches. Thiis as cam 141 rotates from its normal position, as shown in Fig. 4, and the cam-surface thereof recedes from the cam-roll thereon the clutch-acti'ating spring 142 forces fork-lever 85 down, thereby catsing said friction-catch 60 to engage and said shaft 41 to rotate, and sinu'dtaneorsly the clutch 69 through the aciion of link 137 and arm 136 is \\'i thdra'wn or unclutched, causing the measurer-shaft 67 to cease to rotate. Then as the cam 141 contim.es to rotate a raised portion is provided thereon adapted to engage the roll 14() upon its arm of the bellcrank lever 83, whereby rock-shaft 84 is rotated in the opposite direction to that of the ICO 844,569 i" f f 1 9 'spring action, so that clutch 60 is withdrawn or unclutched and shaft 41 ceases to rotate, and simultaneously clutch 69 is forced into its socket or clutched and said measurershaft 67 begins to rotate.

The mechanism for actuating the sliding key 2 consists of a cam-groove 145, formed in the cam-disk 128 on line-sleeve 110, which operates upon the lever 146, pivoted at 147 to the frame, and which in turn actuates the forked lever 148, ivoted at 149 to the frame, and in the forke end of which are two pins adapted to enter a circumferential groove in the slide 78 upon measurer-shaft 67, upon which is mounted the pawl 6, that engages with the teeth of the rack 4 of the key 2. The cam 145 is so laid out that after it has carried the slide 78 to its full'height, and thus raised the sliding key 2 to its proper gear, a dwell is provided onv the cam to hold the key in that position while the gear with which the key 2 engages is being brought to its normal lace of rest, whereupon the slide 78 is with rawn and by engagement with a lug 150 at the lower end of the sliding key 2 returns the key to its normal place of rest, as shown in Fig. 4. The cams upon the linesleeve 110 are so constructed and arranged relatively to one another that immediately after the cam 145 has raised the key to its gear-selecting position cam 141 operates to throw the clutch 69 into engagement, whereby the dividing-gears 75 are set into operation to measure the line and at the same time ascertain the thickness of spaces required to jlistify the same, which operation brings the line-sleeve 110 to the completion of its first two-thirds rotation, where it is arrested by means already noticed. As the cam 141 finishes said two-thirds portion of the revolution of the line-sleeve it presents a notched portion 151 in the periphery thereof to the roll 14() Upon the bell-crank lever 83, which permits the spring 142 to again shift the clutches, so that the type-driving shaft 41 will be thrown into o eration and the line will be carried forwar in the typeway until the cam-wheel 80 upon word-sleeve 56 operates upon the other arm of the bell-crank 83 to release the friction-clutch 60 on the line-driving shaft 41.

I will now describe the means employed for operating the slide 52, which, as has been seen, is employed to furnish an abutment against. which the line is measured. It consists of the vertical shaft 53, on the upper end of which is the stop-engaging arm 54, which enters a suitable notch in the slide 52, the lower end ofthe shaft 53 being provided with a lever 152, which has ashort arm 153 adapted to engage with the raised portion of the cam 55 upon the word-shaft sleeve 81, which as it begins to make its first rotation strikes said arm 153, operating to withdraw the slide 52 from its position across the channel of the typeway 40. The jaw 52 is again returned to its position across the channel by means of the long arm of the lever 152 upon the shaft 53, which is adapted to be engaged by the upwardly.- extending member 131 (see Fig. 3) of the slide 126, which in turn is adapted to be engaged by the governor-arm 57 upon type-driving shaft 41. The governor-arm 57 is so placed upon the typedriving shaft 41 that it impinges upon said vertical member 131 of the slide 126 only after the line has been carried out of the typeway, so that it will, through the medium of shaft 53, force the stop-j aw 52 into position across the channel of the typeway for the measurement of the succeeding line.

1 will now complete the description of the means employed for operating the clutch mechanism of the line and word sleeves 110 and 81, respectively.

l have already pointed out that uponv th horizontal slide 126 is an arm 130, extending into the pathway of the radial arm of the spring clutch-pawl 114 (see Figs. 13 and 4) upon the word-sleeve S1, which may be moved out of the path of travel of said clutchpawl and said sleeve started in motion by action of the cam projection 127 (see Fig. 3) striking against the end of said slide 126. The cam projection 127 is so placed upon the periphery o1 the cam-disk 128 that when it has actuated the slide 126 it has completed the first two-thirds of its revolution and operates to carry the stop-arm 130 out of the position in which it has been holding the clutch-pawl 114 from engagement with its actuating toothed wheel 118 upon the wordshaft 56. The slide 126 will remain out of engaging position with the clutch-pawl 114 until it has been brought back into such engaging position by means of the governorarm 57 on shaft 4 1 striking the upright vertical member 131 of the slide 126 at theconipletion of the work of the word-shaft, which through the rotation of said shaft 41 has caused the line to be carried out of the typeway 40 into a galley or other means provided for its reception. The slide 126 as it is pressed to one side by the action of the cam projection 127 interposes its projecting arm 125 into the path of the radial arm of the spring clutch-pawl 113 (see Fig. 3) of the line-sleeve 110 as it withdraws its other projecting arm 130 from engagement with the word clutch pawl 114, the projecting arm 125 being placed, as 1 have already stated, circumferentially of the clutch-pawl disk 111 with reference to the rotation of said sleeve approximately at the two-thirds revolution thereof. It will therefore be readily understood that when the governor-arm 5 7 reverses the motion of said slide 126 it will operate to arrest the rotation of the word-sleeve by reason of interposing the stop 13() luto l the path of clutch-pawl 114, and will IOO IOS

simultaneously move stop-arm 125 out of engagement with line-clutch pawl 113, allowing the line-sleeve 1'10 to resume and com l'ete its arrested rotation. At the point rnarffingl the complete revolution of the linesleeve 110 is the stop-detent 120which we have already seen arrests the action of the line-sleeve mechanism' at the end of its first com lete rotation.

Vifhile the line-sleeve is standing at the position of partial rotation, Where it is left by reason of the line-clutch pawl having engaged with the stop-arm 125, the word-shaft sleeve. S1 has heen caused to rotate as many times as there are word-spaces in the line to be justied, and the'measuring mechanism and all ofthe parts pertaining thereto have remained in the position to which they have been carried in measuring the line to be justified, except that stop-jaw 52 has been withdrawn; but immediately upon the word-shaft sleeve 81 coming to a stop the clutch-pawl 113 is allowedto engage 'w ith the toothed wheel 117 on the line-shaft 108, and the said sleeve completes its full rotation, returningr to its normal position. I Will therefore now describe the action of the cams which operate during this last third of the rotation of the line-sleeve 110. The cam 155 is employed to return the dividing-gear cones 77 to their normal position (see 1* igs.2 and 3) through caml'ever 1.56, Which forces the gear-returning rack l 157 longitudinally inits slideway, the rack' 157 engaging the pinion 158, secured to the l lower end of register-shaft 76, causing the i same to rotate theshaft 76 and likewise the l measurer-shaft 67 through the gears back to their normal positions. The two shafts 67 i and 76, it will be borne in mind, are still conl nected for this operation by means of the pair of gears connected by key 2, which have i been used in, dividing the measurement of ,l shortage in the line. Synchronously with the action of the cam 155 returning the dil viding-gears 77 75 the cam 159, also carried ,l by the line-sleeve 110, operates to return the type-driving shaft 41, there being provided l for that purpose the cam-lever 160, (see Figs. , l 1, 2,A and 3,) and the lever 161, pivoted at 161 and carrying gear-segment 163, which. l meshes with a gear 164, pinned to thc typedriving shaft 41. The cam-groove 145 in the cam-disk 128 is so constructed that it operates to return the key-shifting slide 78 to its l normal position after the gears have been returned to their normal position of rest, l thereby allowing freedom for the key proi jection 5 of said sliding key!J to pass through the keyway of the series of gears upon the measurer-shaft 67. As the slide 78 reaches the uppermost point of its travel, it engages l by projection 78 with an outwardly-extend- ,l ing arm upon the detent 11, which allows the l slide 7 and fender 8 to be returned to their l normal posltion by the spring 12.

Upon the word-sleeve 81', (see Figs. 1', 3', and 7,) in addition to the clutch-pawl 114, is a cam-disk 92, into determined by the pothe cam-path of which fits the roll upon one of the arms of the lever 93, the other arm of which is attached, by means of a link 93', to the word-slide 90, so that the word-slide is reeiprocated within its guides 91' through whatever amount and in whatever timing may be required.

The operation of the mcchine--From the above description of the various mechanisms constituting t'l'e justifier the operation of the machine will be readily understood with the following description of the movements in the order in which they occur; The operator having pressed the word-key 20 for each word-separator introduced into the line has caused the bar 30 to be carried by its spring 33, having been released by the action of said key into engaging relation with the actuating-arm 100, and the bar 3() has been actuated to withdraw the ejector and allow a separator to be fed out' ofthe channel 22 by the pressure of spring 26 into position to be carried into the typeway, and on it's return movement the ejector forces the separator into the extension of t'he typeway 40, which forms a part of the assemblin -chanand in ront of When the ejector-slide 28 is withdrawn, as above, for each operation of the word or space key 20, it carries with it the lever-arm 39 on the upper end of the vertical shaft 38, which in turn causes the thereby actuating the bell-crank 36, to the end of which is attached the pawl 17, adapted to engage the teeth 16 of the setting-rack 15, which is moved down against its spring 150 a distance of one tooth each time the said actuat- A detent 18, pivoted to the frame at 18', is actuated by the lever that may be manufaetured in accordance with the' setting of theI which spaces may be' either cut from space-timber or cast to thev TOO . tion to which it is carried by the pawl 17.

depressed in the manner above described.

As the rack 15 is carried downward it strikes a pin 19, secured to the slide- 7, having the fender 8, carrying the slide 7 down with it to Whatever extent the setting-rack 15 may be A detent 1-1 is provided to engage the teeth 10 of the slide 7 and retain it in whatever osition it may be carried until properly reeased thereby. As the said slide'7 is forced downward it carries the projecting flange 8 thereon into position to engage the pin 9 of the pawl 6, which operation concludes the setting of the gear selecting mechanism. Fig. 4 shows the slide 7l in its normal position of rest, and Fig. 5 shows the same in its eX- treme position, as in the justification of a line requiring nineteen word-spaces. After having thus de ressed the word-key 20 the last time an having finished composing the line the same is now ready for the ustifier, and the operator depresses the line-key 50, whereupon lever 49 is carried downward from its normal position, as seen in Fig. 4, into the position shown in Fig. 5, and the link 48 is pressed downward, operating upon lever 123 on rock-shaft 121, to which is secured the hooked detent-stop 120,'and said detent 120 is thereupon carried out of contact with the radial arm of the line-clutch pawl 113, which it normally held out of engagement with the toothed wheel 1 17, secured to the constantlymoving line-shaft 108. The detent 120, having thus been removed, the line-clutch pawl 113 drops into engaginer relation with said toothed wheel 117 and the shaft begins to rotate line-sleeve 110. To the same rockshaft 121 to which is attached the detent 120 is secured a lever-arm 123', the outer end of which engages an arm of the pawl 18 in-such manner that as the rock-shaft 121 is rotated to release the clutch-pawl 113 to start the line-shaft sleeve 110 arm 123 moves said pawl 18 out of engaging relation with the setting-rack 15, and the pawl 18, by means of a pin 17/, throws the pawl 17 out of engagement with rack 15, in which position the pawl 18 is held by a dog 21, mounted upon the guide 13 of the rack 15, which drops behind a pin on the pawl 18, so that simultaneously with the starting of the line mechanism the said rack 15 which has now carried the slide 7 to its setting position, returns to its normal position by the action of its spring 15 to be in readiness for the next ensuing line. The dog 21 holds both pawls 18 17 out of engagement with rack 15 until the rack 15 has reached its top or normal position and is then raised by a pin 21 on the i with the rack, the dog 21 then resting on top of pawl 18 until the latter is again thrown out by arm 123.

' It remains to describe still another operation that is accomplished by the depression of the line-key 50-namely, the releasing of the type-driving pawl 43, which is being held out of the line of the channel of the typeway 4() by means of the detent 44. By referring to Figs. 4 and 5 it will be seen that by the depressing of the line-key 50 lever 49, which carries down the link 48, also causes the bell-crank lever 46 to oscillate, and the upwardly-extending arm of the lever 46 is thereby thrown against the longer arm of the detent 44, causing the same to turn upon its pivot and releasing the type-driving pawl 43 and by the action of the pawl-spring will instantly throw the pawl 43 into the line in position to engage the line which has been by the composing machine carried past the pawl 43 into the typeway of the justifier, or if the succeeding line is being assembled at this point in the composing-machine'before the justifier has carried the same forward the pawl will be engaged by such new line and carried forward. The line-sleeve 110 having started to rotate the cam 141, which in its normal place of rest has been holding an arm of the bell-lever 83 in such position that the friction-clutch upon the type-driving shaft 41 is being held out of engagement with its driving counterpart, now moves forward, presenting a depression in the surface thereof, so that thc spring 142, actuating the clutch 60, forces the same into the hub of the constantly-n'ioving gear 61, and immediately the type-driving shaft 41 begins to rotate and through the arm 4'2 and pawl 43 advancesthe line within the typeway 4() until the same reaches the stop 52, which normally stands across the channel of said typeway, whereupon the friction-clutch slips until the cam 14] presents a raised portion, when the clutch 60 is relieved, and by the same action clutch 69 upon the measurershaft 67 is thrown into engagement to cause the mechanisms operated by the shaft 67 to perform their function, as previously described. While thecam 141 has been passing under the roll 140 of the arm 83 previous to presenting the raised portion thereof, and thereby starting the measurer-shaft 67, the cam-disk 128 has been acting upon the lever 146, whichin turn has rocked the hooked forked lever 148 upon its pivot 149, thereby carrying the key-setting slide 78 upward along the lower end of said n'ieasurer-shaft 67, and with it the spring-pawl 6, which is adapted to engage with some of the teeth of the ratchet-rack upon the sliding key 2, and in an arm of winch pawl 6 is a pin Se), adapted to engage with the flange or fender 8, carried by the slide 7, the position of this flange de- IOO IIO

As the fender or flange has been;

upper end of the fender 8 stands in relation to the pin 9, and the key 2 will be moved lip by theslide 78 correspondingly.

Therefore as the line has been carried forward to the Stop 52 the slide-key 2 will have been carried upwardwithin its guid eway 3 in the shaft 67 toiwhatever gear 75 shall have been predetermined by the particular tooth of the rack j 4- on the sliding key 2 which the pawl 6 has been allowed to engage. by the position of thefender 8 of the slide 7, and thus a pair of gears is selected according to the number of As the slide 78 reaches t 1e upper limit of its stroke the hooked projection 78' of the slide 78 engages the detent 11:, extending into the line of travel of said hooked projection, and allows the slide 7 to return toits normal position by means of the spiral 'spring 12, by which it is actuated. The operation of setting the key 5 to select the'proper gear 75 to be employed in justifyingl the line now being acted upon having thus been completed, the measurer-shaft 67 is started in rotation in the manner already described, and the particular gear 75 which has been selected will, through the gear 77 of the register-shaft 76 corresponding thereto, cause the shaft 76 to rotate, carrying with it' the gear-sector 167, rack 1.68, and spacedetermining gage 169, thereby setting the same to determine the proper width of the justifying-spaces. Fig. 6 shows the parts with the rey set for a line of nineteen spaces. At this point the line-shaft sleeve 110 by forces the slide 126 into a position so that its extension 13() releases the spring clutchpawl 114, secured to the disk 114 of the word-sleeve 81, so that the word-sleeve 81 begins to rot te.

word-sleeve in the manner described it also carries a second arm 125 into the path of the radial arm of line-sleeve olutch-pawl 113, thus unclutching itself and causing the sleeve to come to a stop. The line-shaft sleeve 110 has now reached approximately the twothirds point in its rotation, where it will remain until after the word-shaft sleeve 81 has completed its allotted number of rotations in spacing the line, when the line-sleeve will again be brought into operation, returning the various parts which have been operated thereby back into their normal position. As theline-shaft sleeve reaches its temporaryT stoppinglace the depression 151 in the cam-whee 141 has been brought directly under the cant-roll 140 of the bell-crank 83, and the sleeve 110 is held stationary thereby.

Previous to-the point last described having As the slide 126 is thus carried to re ease the clutch-pawl of the' line that may be fed into the justiier.

been reached the clutch of the measurershaft 67 has been in engagement; but it is now allowed to be released by action of a spring 142, which will at the same time throw clutch 60 of the type-driving shaft 41 intol engagement, thereby resuming the operation of advancing the line in the typeway in order that it may receive its permanent justifyingspaces as well as to make room for the new Ifore the line can proceed, however, the

stop-jaw 52 must be withdrawn, which is accomplished by the action of the cam 55-uponl the word-shaft sleeve 81, the cam 55 actuating the lever 152,secured to the lower end of the vertical shaft 53, thereby rocking the' shaft to the extent necessary to move the arm 54, secure-d to the up er end of the shaft, and withdraw the said s ide 52 from across-- the typeway. The stop-j avv-actuating cam 55 is so disposed upon the word-shaft sleeve 81 that it willoperate upon the lever 152 immediately upon the said word-sleeve 81 being put into action and-before the line-sleeve 110 has come to its first stop, and therefore does not present the depression 151, above referred to, on the surface ofA the cam 141 to allow the shifting of the clutches 113 114, as described, until after Ythe word-shaft sleeve 81 has operated in the manner aforesaid to- The unjustified:

Just before the pressure is released from the line as it is being held against the word-slide 90 the cam 92 upon the word-sleeve operates to throw the lower end of the lever 93 outward, thereby rocking the lever upon its pivot and thrusting the word-slide 90 -forward into the position shown in Fig. 11 and then returning the lever .93 in the opposite direction until it reaches the position shown in plan view in Fig. 12 andv 1n. elevation in Fig. 13.
