SPECIFICATION forming part of Letters Patent No. 693,145, dated February 1 1, 1902 Application filed July 20, 1900. Renewed December 14, 1901. Serial No. 85,939. No model.)

To (bi/Z whom it may concern:

Be it known that I, FRANK MOCLINTOOK, a citizen of the United States, and a resident of the city of Mount Vernon, in the county of Westchester and State of New York, have invented a new and useful Improvement in Machines for J ustifying Type, of which the following is a specification.

My invention relates to an improvement in -ro machines or apparatus for justifying and spacing out lines oftype to a uniform length or measure, and particularly to that type of justifying-machine which is described and claimed in certain Letters 7 Patent granted upon my application the first of which is numbered 608,002 and is dated Ju1y26, 1898, and the second of which is numbered 635,866 and is dated October 31, 1899.

The invention will be best understood by reference to the accompanying fourteen sheets of drawings, forming a part of this specification, in which Figure lis a plan view of the machine. Fig. 2 is a plan, partly in section, of the upper end of the machine, showing the justifier about to operate. Fig. 3 is a plan view, partly in section, showing the justifier actually in operation. Fig. at is a rear elevation of the machine indicated by line A A in Fig. 1. Fig. 5 is a side view of the machine, showing the device for actuating the line-holder indicated by line B B in Fig. 1. Fig. 6 is a de tailed view of parts of the mechanism for actuating the line-holderindicated by the line C O in Fig. 5. Fig. 7 is a cross-section on the lines D D of Figs. 1, 2, and 3, showing the cams, wedge-hook, and space-rack in an advanced position. Fig. Sis a plan view of particular mechanism shown'in Fig. 7. Fig. 9is a vertical cross-section on the lines E E of Figs. 1 and 2, showing the clutch for throwing the justifying mechanism into gear. Fig. 10 is a vertical cross-section on the lines D D,

Fig. 16 5'5 shows the pivoted support for the space-bar before the space-bar is driven into the lineholder. Figs. 17, 18, 19, 20, and 21 are en larged detailed views of the line-holder and the space-bar, Fig. 20 being a section on the line K K. Fig. 22 is a plan view of the particular parts of the machine which effect the justification proper, and Fig. 23 is a vertical cross-section of the same parts on the line L L of Fig. 22. I

Similar letters and numerals refer to similar parts throughout the several views.

The following is a general description of the machine.

The following elements found in this ma- 7o chine are common to all justifying-machines of the present type.

c is a sliding line-holder in which the type are assembled and in which justification is effected.

f is a vertical plate against which the lineholder slides and which forms its inner face.

y is a slot on the inner face of the plate f opposite the line-holder 0, arranged to receive the extremities of the space-bars as they are inserted therein. I

a, is the main table of the machine; it, the outer supporting-frame, which serves also as a bearing for the driving-shaft t; s, the typechute through which the type enters the lineholder 0. I I

Z) and d are two parallel channels in which the line-holders travel downward and upward, respectively. The former is formed on the upper face of the plate a and the latter go by the plate 819.

e is the series of space-bars.

The plate f contains a groove g, through which the hooked slide travels which drives the line-holders. 5

m is the raceway, formed in the plate a, in which the space-bars e are returned from the lower to the upper end of the machine. 01 is the plate which covers the same.

j is the'channel in which the spring which 10:: returns the space-bars rotates.

Z is the space-holder.

n is the main bed-plate of the entire machine. V V

p is the key which actuates the space-bardriving mechanism.

t is the main driving-shaft; w, the justifying-shaft; 0, the sleeve upon the justifying shaft by means of which the justifying mech-- anism actuated by it is connected with it.

q is the driving-pulley.

r is the end plate of the machine; It, the key which actuates the line-holder-advancin g mechanism; u, the galley on which the justified lines of type are assembled.

2 represents the assembled line in the lineholder.

The Zine-holder and space-bara-Two lineholders 0 c are provided with each machine, which are really composing-sticks having the capacity for a single line of typeand the necessary temporary spacing. devices. The lineholders are of the shape shown in Figs. 17 to 21, inclusive.

12 is the type-recess cut on the face of the line-holder, which is of a width and depth to correspond with the size of type used and extends the entire length of the line-holder. It

is closed at the front end by a fixed stop 2 .and at the rear end bya movable block 6. A i longitudinal opening or slot 1 is provided extending almost the entire length of the-lineholder. The block 6 is adapted to be moved longitudinally along the recess and to be securely clamped to the rear-wall of the lineholder at any desired point by means of the screws 5, Figs. 18 and 21. The line-holder contains in its interior a curved rib 10 for the purposes hereinafter described. The movable block 6 is provided with a spring-plate 8, which may either be pivoted at one end or side of,,the block 6 at the point 9 and held normally in the position shown in Figs. 17 and 18 by means of a spring 21, encircling thesliding pin 7, or else it may be supported upon pins 7 7, sliding in suitable openings in the block 6 and held normally in the position shown in Figs. 20 and 21 by means of the spring 21. The object of making the plate 8 movable is to enable it to be moved .at the proper instant out of the path of the cam 3, which is constantly rotating upon the shaft and serves to throw the type forward in the recess 12 as fast as it is assembled therein. In order to draw in the plate 8 and permit it to pass the cam as the lineholder moves down its track, a beveled plate '22 is provided, (shown in Fig. 3,) attached to the edge of the side plate f, which as-the lineholder moves down the groove 19, in which it D travels, engages with the face of the plate 8 and pushes it back a sufficient distance to enable it to pass the cam 3, and when it has passed by the cam the spring 21 thereupon throws the plate 8 out to its original position, and thus closes the end of the recess 12, as before. The space-bars 44 are shown in detail in Fig. 19. They are provided at their upper rear ends with a hook 20, as shown.

The tapering portion of the space-bars 44 varies in thickness from somewhat less than the thinnest space-blank which it is desired to use up to the thickest. The lower edge 19 of each of the space-bars from the point 17 to the point 18 is cut away for a sufficient. distance to make the height of the space-bar such that space-bar is first inserted into the line as a temporary space the notch 15 will rest on the rib 10, and the spring of the two parts of the space-bars separated by theslot 14 will'serve to hold it securely in place. It will be-evident that this construction will allow of the space-bars being readily driven farther through theline and will also prevent them from beingaccidentally withdrawntherefrom. I

Upon the top-plate a rests a plate 70,- car 7 rying on its outer face a series of bristles 73, the ends of which engage with the outer-ends of the space-bars, and thusprevent them from shifting their normal position at right angles to the line of type in the line-holder after insertion therein. v the top plate by means of set-screws 72, passing through the slots 71 in the plate.

The type-advancing cam.-The type is kept spaces used is 4 This plate is-adjustable' on constantly advanced in the line-holder as it 1 is assembled by means of:.a rotating cam 3.

This cam is placed at the end of a shaft 60,-

passing through a suitable bearing in the upper part of the plate-68, as shown in Figs. 2 and 5, which carries at its extremity a small pinion 61, the teeth of which-are arranged to mesh into the teeth of an idler 62, rotating on the shaft 61 on the plate 65. This idler engages in turn with a gear 63 at the extremity of the main driving-shaft '6. The relations of the parts are-such that the speed of the shaft 60 will be very much increased and the cam will rotate continuously and very rapidly. The shape of the cam is such that as it comes in contact with the types assen1-- bled 'in the line-holderit will throw them and the space-bars forward and cause them ,to be set up in a homogeneons line. The plate 68 is pivoted in the-side plate f, as shown in Fig. 2, in sucha manner that the top part, in which the cam-shaft 60 has its bearings, may be moved to and fro a shortdistance in order that the cam may-be adjusted properly to the position of the type-chutes. The set-screws 66, which pass through the lugs of the plate 68, which is secured to the side plate f, and,

which lever is pivoted at the point 113 to the impinge on either side of the plate 65, serve to adjust it accurately and then to retain it rigidly in such position.

The space-bar-insertz' ng mccham'sm.1nstead of ordinary space-blanks tapering or wed ge-shaped space-bars are employ ed,which as in other machines of the character of the present machine, are inserted temporarily crosswise through the line between the words as composition proceeds or as the type is transferred to the line-holder and which are replaced mechanically by ordinary space blanks, as will be fully described hereinafter. A series of these space-bars is shown, (designated as 6,) and the individual bars composing the series are designated by 44. The position of the bars prior to insertion will be best seen by reference to Fig. 2, in which the series is shown assembled at the upper end of an inclined raceway on, held in position by a spiral spring-coil 905, rotating in a groove j, the effect of which will be referred to hereinafter. of the-raceway m in Fig. 2 the space-bars are raised one by one when they are to be inserted, and as fast as they are raised they are pushed forward into the line-holder at the proper point.

The inserting mechanism consists of two 'parts- -first, an elevating mechanism for lifting each single space-bar from the storagechannel at the head ofthe raceway up to the level of the line-holder, and, second, a spacebar-inserting rod which forces the space-bar forward into the line-holder after it has been thus elevated. These features will be best explained by reference to Figs. land 10, taken in connection with the detail views, Figs. 14, 15, and 16.

(a) The elevating mechanism: In the detail views, 44: represents, as before, the foremost of the series of space-bars shown in the raceway held in position by the spiral spring 905, the raceway being formed between the main plate a and the cap-plate 5, both of which are inclined at the appropriate angle at which the machine works. 100 is the space-bar-elevating plate, which is arranged to slide vertically in the end plate 0 of the machine. This is attached to a vertical plate 101, arranged to slide in suitable ways 102, out in the inner face of the plate 4". The extremity of the plate 101 is pivoted to a lever 103 by the screw 104. A spring 105 is provided, attached at the upper end to the pin 106, upon the outer face of the end plate r and atthe lower end to the pin 107 upon the face of the sliding plate 101, which is in turn attached to the plate 100.

(b) The inserting mechanism: The spacebar-inserting mechanism will be best seen byreference to Figs. 3 and 4. It consists of a sliding plate 110, attached to a rod 109 andsliding in a groove in the upper surface of the end plate r, attached at its outer end by pin 111 to the long arm 112 of a bent lever,

From the position shown at the top frame it and is provided with a short arm 11 1, carrying a looselyrotating roller 115. A spring'12'5 is provided, attached at one end to the pin 126 upon the long arm112 of the lever and at the other end to a pin 127 on the outer surface of the end plate r of the machine.

The space-bar-inserting mechanism and the space-bar elevator are both actuated from the driving-shaft t by means of suitable cams.

(Shown indetail in Figs. 2, 4, 8, and 12.) The driving-shaft t rotates in suitable bearings 39 and 4:0 in the platefand the frame h, respectively, and is driven from any convenient source of power. It carries a collar 117 ,which is attached to'it by the pin 116 and which rotates with it. Upon the shaft t is a loose sleeve 119, carrying at one end a cam 118, the outline of which is shown by the dotted line in Fig. 13. The roller 115 engages with the periphery of this cam and is kept in contact with it by the spring 125, so that the lever 112 is actuated by the rotation of the cam 118. Attached to the other end of the sleeve 119 is a second roller 120. The roller 120 is provided with an interior cam-groove 128, out on its face, as shown in Figs. at and 13, within or along which rotates a roller 122, rotating on a pin attached to the lower end of the arm- 121, which is in turn attached by the screws 12 1 to the lever 103, which actuates the plate 100, and it will thus be apparent that as the cam 120 rotates the cam-groove 128 will cause the roller 122 to move and the lever 103 to rise and the spring 105 to be retracted. The form of the cams 128 and 118 and their position on the sleeve are such that as the shaftt rotates they will be so timed with reference to each other that the cam 118 will first cause the space-bar-elevating mechanism to raise the foremost space-bar and then draw down the lever 103 to its normal position, and after the proper interval of time has elapsed the cam 118, by reason of its form, will begin to operate upon the roller 115, and thus cause the forked lever 121 to be drawn in by the spring 125, and the space-bar-insertingrod 110 will push the space-bar which has just been raised in place into its place in the lineholder.

In order to throw the mechanism in and out of gear, a ratchet-wheel129, the teeth of which are of the shape shown at 131, is provided, keyed to the rotating shaft 25 in close proximity to the outer surface of the cam 120. The face of the cam 120 carries a pivoted dog 132, attached at the point 133, provided with a spring 135, which causes the dog to be normally thrown forward and the tooth 134 to engage with the teeth 131 of the wheel 129. 1

complete revolution.

a wire 142, connected with a suitable key-le-t ver p, -Fig. 5, so that when the key-lever is,

normal position by means of the spring 141'. As the cam 120 completes its revolution the tail 136 of the dog 132 engages the hook 137 on the lever 138, which withdraws the tooth 1 34 of the dog 13 from its engagement with the ratchet-tooth 131, and the cam will cease to rotate. In order to prevent the clattering of the dog 132, which would occur if the cam 120 were not kept from rotating backward, a brake-shoe 143-is provided, engaging with the periphery ofthe cam, pivoted at 144 to a bearing 145, attachedby the screw 146 to the plate at and held against the periphery ofthe cam by the spring 147. 1

It is essential that the movement of the front end of'a space-bar in entering the line of type shall be so timed that it will not strike 3 either the cam 3 or the last type -set' in the lineholder. It is necessary, therefore, to so time the revolution of the cams 118 and 120 with respect to that of the cam 3 that-whenever a space-baris inserted into the line'the cam 3 will be in the position shown in Figs.

'2 and 17,'allowing the thin end of the space- -bar to be inserted into the line of type between the hub of the cam and the last type set in the line-holder. This is effected" by meansof the gear- wheels 61 and 63, which are connected by means of the idler 62 inconnection with the teeth 131 on the ratchetwheel129. These are so proportioned that the revolution of the main shaft t and of the ratchetwheel129throughouta distance equal to-the pitch of the teeth 13lwill cause one revolution of the cam-shaft 60. In other words, one complete revolution of the main --shaft t will cause the cam-shaft 61 to make as many complete revolutions as there are teeth on the ratchet-wheel 129. In the machine :shown the cam-shaft is geared to make seven revolutions to each revolution of the main shaft 1., and the cam 3 is secured to'its shaft.

61 in such a position that the entering point r of a space-bar will always find it in the positionshown in Figs. 2 and-17, whichever one of the teeth 131 of the ratchet-wheel129 may. be engaged by the dog 132. v

- For the purpose of adjusting the space-bar elevating and driving mechanism with respect to. the cam 3 the rear or upper end of the top plate a is cut away, as shown in Figs.

'2 and 15,and an adjustable angular end plate 275 is provided having the slots 276 and screwed to the bed-plate by the-screws 277 passing through the slots. By loosening the screws the plate may-be shifted up and down, carrying with it the, driving and elevating mechanism.

In order to hold each space-bar in the elevated position while the space-bar-inserting mechanism is acting upon it, a pivoted plate 267is provided; (Shown in Figs. 14, 15, and 16.) This is pivoted at the lower end at either side by the pivots 261 to a plate 263, which latter plate is attached to a cap 264 by means of the screws-265. Thecap-plate 264 is attached to the upper end ofthe plate 0* by the screws 266 and is slotted throughout its width up to a certain point, there terminatingin a shoul der 268, as shown in Fig. 15, arranged to en gage with the lug or hook on the end of the space-bar in order to limit the forward movement of thelatter.

The plate 267 is normally held in a forward position by means of a spring 262, which forces it constantly forward. When the foremost space bar in the line is raised by the elevating-plate 100, the plate 267 is forced back against the spring 262, and the plate 100 passes by'ihe plate 267 and holds the spacebar in the position shown by the dotted lines in Fig. 14 for an instant. The-instant that it begins to return the spring 262 forces the plate 267 outward and under the space-bar and holds it-there while the space-bar-driving mechanism operates on'it.

The adjustable plate 275 is beveled, as shown by the dotted line 278 in Fig. 14 and the shaded surface in Fig. 15. .This enables the line-holder o in rising to move forward a sufficient distance for the frontline-stop 2 in the line-holderto clear the cam 3.

' TheZine-holder friction-braka-During the composition ofa line some sort of device is necessary which will hold the line-holders to a certain extent and prevent it moving too rapidly down the track or way while the types and space-bars are being assembled therein.

The form of device employed for this purpose is shown in Figs. 3 and 12. This consists of a vertical plate 50, slightly beveled at the rear end 51, as shown, of such dimensions as to fit into the channel on the side of the lineholder traveling onthe track 6, out on the face of the cap-plate. The plate is fastened to the extremity-of a sliding rod 53, which isarranged to slide in a suitable opening or seat 54, cut longitudinally through the cap-plate,-the movement of which is limited by a pin passing through a slot 56 in the rod 53. Theouterendofthe rodimpingesagainst a coil-spring 57, placed in the continuation of the channel 54, the outer end of which abuts against a thumb screw 58, mounted upon a screw-pin 59', which screws into an appropriate threaded surface out on the inner face of the channel 54, so that by turning the thumb-screw the spring 57 will be compressed and the plate 50 will be forced forward against the line-holder-with anappropriate degree of pressure. By means of the beveledextremity 51 the groove 25 on the side of the line-holder is shown in detail in Figs. 1, 2, 3, 4, 5, and 6..

For the purpose of carrying the line-holder c and permitting it to travel forward an inclined track or way I) is provided, formed upon the top of the plate a by the inner edge of the cap-plate 43, as shown in Fig. 23 in cross-section. The inner surface of the plate f contains a groove g, running its entire length. The form of this groove will be more particularly shown in Figs. 6, 7, 8, and 9.

In the groove g is a slide 159, which contains a recess 160 at its rear end, as shown in Fig. 2. This recess contains a pivoted hook 161, pivoted at the point 162 and the longer end of which is prevented from extending too far out into the channel in which the lineholder travels by means of the extended end 163. The hook is normally thrown outward by means of a spring 164, but when the slide is retracted the face of the hook 161, coming in contact with the end of the line-holder, compresses the spring 164, and thus passes by the line-holder, and afterits passage is thrown forward to its original position and thereupon engages with the rear end of the line-holder c. It will be obvious that when the slide 159 is again moved the hook 161,.attached thereto, impinges against the rear end of the line- -holder and causes the same to be moved for- In order to actuate the slide 159, a pin ward. 166 is provided,passing through the slot 165, the length of which is shown in Fig. 2 and the precise position of which is shown in Figs. 5, 7, 9, and 10. Through this slot passes the pin 166, which is attached to the slide 159 and to either side of which are attached two cords 167 and 168, respectively. The cord 167, as will be seen by Fig. 5, passes over a grooved pulley 169 at the point shown at the lower end of the side plate f, and thence passes over a horizontal grooved pulley 170, placed atacon- I venient point, thence over another vertical pulley 171, arranged in an equally appropriate position, and terminates in a weight 172, to which it is attached by a ring 173,formed at the top of the weight. On top of the weight 172 is placed a loose weight 174, containing an opening in its center 175, through which the cord 167 passes, and a bracket 176, provided with a ring 177, is so arranged with reference to the weights that when the weight 172 falls it will pass through the opening in the ring 177. The weight 174 is of greater diameter than the ring, so that when it falls with the weight 172 it will beheld upon the ring 177, attached to the bracket 176, and will thereupon cease to add its weight to that of the weight 172. It will be observed that the effect of the weights 174 and 172 upon the cord 167 isto normally draw the pin 166 downward and with it the slide 159.

The upper cord 168 passes over a grooved pulley 178, mounted on the shaft 179, and is attached thereto rigidly at the point 180. To the face of the pulley 178 is attached the campulley 181, grooved on its periphery, as shown in Figs. 1 and 5. To the point of the cam.181 at the point 182 is attached a cord or chain 183, passing over a grooved loose roller 184, connected at its lower extremity with the cross-head 185, attached to the piston-rod 186 of a compressed-air cylinder 187. The rod 186 is attached to the piston 188, sliding in the hollow chamber 189 of the cylinder 187, and it will be obvious that as long as the chamber 189 is filled with compressed air the piston will assume the position shown in Fig.

6 and the cross-head 185 the position shown in Fig. 5, as well as in Fig. 6. Compressed air is supplied to the chamber 189 from a pipe 191, connected with any convenient source of supply, through a port 192. This port is opened and shut by means of the sliding valve 193, controlled by a spring 194, which sliding valve contains in its interior an outlet-port 195, so that when the valve 193 is in the position shown in Fig. 6 the chamber 189 is constantly kept full of compressed air; but when the valve 193 is slid upward the port 192 will be closed and connection will be made through the air-port 195 with the interior of the chamber 189, and the compressed airin the chamber 189 will flow out through the port 195 into the air, and the piston 188 can then be retracted by the effect of the weights 172 and 174. For the purpose of opening the valve 193 to allow the escape of the compressed air a key is provided, pivoted to the side plate f at the point 196. This lever is composed of two arms 197 and 198, to the longer of which is attached a finger-piece 199 and to the upper of which is attached cord 200 at the point 201. attached to a lever 202, pivoted to a shaft 203, held upon bearing 204. The other extremity of the shaft carries a similar lever 205, set at an appropriate angle, which is pivoted to the extremity of the sliding valve 193 at the point 206. \Vhen, therefore, the finger of the operator is pressed upon the finger-piece 199 of the key 76, the cord 200 is retracted and the valve is opened. A spring-catch 207 is provided, pivoted at the point 208 to the side plate f, arranged to engage with a stud 209 upon the shorter end 198' of the key 7c. When the key 70 is depressed, the hooked end of the lever 207 is forced downward by the spring 210, engages with the stud 209, and holds the valve open. For the purpose ofclosing and releasing the device automatically the pin 166, when it reaches the lower end of its line of travel,

The other extremity of the cord 200 is trips the outer end 211 of the lever 207, extends the spring 210, and raises the hooked end free of the stud 209 upon the lever 198,

whereupon the spring 194 will close the valve- 193 to the air and permit the compressed airto enter again through the port 192, thus filling up the chamber 189, driving down the piston 188, drawing down the cord 183 by means of the cross end 185, and causing the slide 159, by means of the cord 168 and intermediate cam mechanism, to be raised to its original position. Then the key 70 is actuated and the air passes out of'the cylinder 187, at that instant the slide is moved downward by theforce of the weights 172 and174 acting upon the cord 167. During the earlier part of the line of travel a certain amount of friction is necessarily exerted upon the lineholder by means of the plate 50, as above described, and hence a heavier weight is necessary during the first part of its travel than is necessary or desirable after it has passed down to the justifying mechanism and is no longer in contact with this plate. Hence the position of the weights 172 and 174 with reference to the ring 177 is so timed that the instant the line-holder is released from the friction-plate the weight 174 will come in contact with the ring 177, and the cord 167 will thereupon be relieved of its Weight and will be carried down by the force of the weight 172 only to the end of its line of travel. When the cylinder 187 is being filled with compressed air, the weight 17 2 will be raised until it passes up through the ring-177, and

thereupon it will carry with it and raise the Weight 174, and when the position of the cross-head 185 (shown in Fig. 5) is attained the weights 174 and 172 will assume their original position, as is shown in this figure.

In order to facilitate the'raising of both weights without unduly lengthening the stroke of the piston 187, the cam 181 is given an increasing diameter proportionate to the increased weight, so that as the weight increases the radius of the cam increases, and

thus the same effect is accomplished as would be by making the stroke of the compressed- .the justifying-slide is operating.

air piston longer.

' It will be evident that other mechanical means than the compressed air cylinder shown may be employed to draw up the slide 159 and weights 172 and 174 to their operative position without departing from the principle of my invention.

The ZinahoZder-holding mechanism.The object of this is to hold the line-holder while This will be best shown. by reference to Figs. 1, 3, 7, and 8. It consists of a slide 600, arranged to slide in suitable guides 601 upon the bedplate a. The inner end of this slide carries a block 602, to which is attached a slide 609, the inner end of which is arranged to impinge against the outer face of the line-holder, as shown in Fig. 7. The slide 600 is normally forced forward and held against the lineholder by means of a spring 603, placed underneath the slide and between it and the bed-plate, one end of which'spring is attached to the slide at the point 604 and the other end of which is'attached to the bed-plate at the point 605. The slide is retracted by means of mechanism attached to and operating with the sleeve 0. This mechanism consists of a earn 606, keyed to the sleeve 0, which cam engages with a roller'607 at the extremity of a bracket 608, attached to the-slide 600. When thesleeve o is at rest, the slide is held in the position shown in Figs. 2 and 10. The position of the cam 606 on the sleeve 0 is such that after the operation ofremoving the spacebar and inserting a space-blank in lieu thereof is completed the raised part of the cam 606 again engages the roller 607, therebywithdrawing the end of the slide 609 from contact with the line-holder, which is then free to move along its track until another space-bar, by engaging the stop375 and the end face of the slot 13, brings it to rest.

The space-bar-dricing and space-selecting mechcmrlsm.-By this title is designated that particular mechanism which arrests the movement of the line-holder and then drives the space bars farther through the line, thereby increasing the spacing between the words until the line has been expanded to the limit of the line-holder, and withdraws the space-bars one by one, inserting at the same-time in lieu thereof space-blanks of such individual and aggregate thickness as will accurately and properly justify and space out the line. I The principle of the present machine differs materially from that of former machines of the same general characterin that instead of using two independent mechanisms, one for driving in all of the space-bars simultaneously and a second one for afterward driving them in suc- V cessively for the purpose of'apportioning the fractional excessof spacing, the same result is accomplished by a single mechanism operating intermittently, whereby the line is progressively expanded to the limit of the lineholder.

In order to understand the difference in principle between the mechanism" employed in the present machine and that employed in the earlier machines, attention must be called to the conditions shownin Figs. 2, 3, and 22. These figures show a line-holder containing a line of type set up in the appropriate channel in the line-holder, with seven tapering spacebars inserted therein between the separate words. Ileretofore when permanent or temporary spaces have been used in connection with automatic mechanism for justifying and spacing ordinary movabletype it has been thought necessary to provide a primary bunter extending along the entire length of the line, which may be driven or forced against the thick ends of all the tapering devices in theline, therebydriving them simultaneously farther through the line until the :increased spacing thus formed between thetypes con-
