To all whom it may concern.

Be it known that we, ALFRED KRAU analytical chemistfa citizen of the Frenoh'Republic, residing at 10 Rue Marbeuf, Paris, France, and'NoRMAN' COLLINS, engineer, a

- subject of the King of'GreatBritain, residing cording as the type-faces are in relief or are sunk. v I

For the sake of brevity the word matrix? as used hereinafter is to be understood as denoting a surface or body of plastic material adapted to beimpres'sed by type for the purpose of providing either a stereotype-mold (or matrix,'properly so-called) or a print ing-surface.

The machine'comprises a key-controlled rotary barrel, juxtaposed" type disks, and means of adjusting the type-disks and justifying the composed line of matter, also means for producing a matrix by the successive impression of successively composed lines.

Figures 1 and 1 together form a part plan of the machine; Figs. 2 and 2 together form a front elevation. Figs. 3, 4, 5 are cross-sections on lines 3 3, 4: 4, and'5 5 Fig. 6 shows the reversing-clutch. Figs. 7 to 11 show details on a larger scale. the matrix-carrier. Fig, 13 is perspective part view of'the same, portions being broken out toshow the construction. Fig. 14 is a similar view showing the two parts of: the matrix-holding grid separated from one another. Fig. 15 is a similar view of part of the matrix-carriage and of the frame or seat for the grid. Figs. 13, 14, and 15 are drawn to alarger scale.

Each key A operates a detent for limiting the rotation of a barrel B by engaging a stud Z) thereon. The pitch of the studs 1) corresponds to that of alternate types onthe type- Fig. 12 is a plan oi disks, and each detent has two operative positions difiering in angular relation to the barrel to an extent equal to half the pitch of the studs b, so that each key A will correspond to two adjacent types, the setting of the one or other of those types being determined according as the detent is brought-to the'one or other of its two operative positions. The barrel B is geared frictionally with a continuously-revolved shaft 0 and positively with the carrier of thetype-disks D, so that the latter will receive successive angular movements corresponding to those of the barrel.

Each disk D has laterally-flexible arms, each carrying a type-body cl or a space-block. The type bodies may be fixed or may be readily movable to effect protraotion of the composed line beyond the normal radius. Each type-disk comprises capitals, small let tors, and other usual character s, also two or more space-blocks and meansof justification. The disks D are independently adjustable and are rotated about a shaft'E by means of driving engagement between the disks and the barrel, the said driving means being so retracted'after each angular adjnstmentthat each disk in turn is disengaged, thedisks being then held by retaining means, which engage with the disks in succession as they are disengaged from the driving means;

Justification is efiected concurrently with the movement of the composed line to the impression position. not only spacing the words to fill out the line, but also closing together the letters of a word. As each disk comprises letters of various widths, it requires for its revolution a space equal to the width of the widest type-body, and the type-bodies of adjacent disks must therefore be capable of being moved toward each other in order to obtain proper spacing of the narrow letters. The type-carrying arms are therefore flexible to permit the constituent type-bodies of a word to be moved slightly out of the planes of their disks, such closing together being included under the term justification.

The impression mechanism comprises a matrix-carriage H, movable toward the type disks, shifted after each impression line by By justification is meant line, both movements being imparted from shaft 0 through mechanism controlled by an impression-key I.

The matrix may either be a single block or a plurality of strips of plastic material, each strip for the impression of a single line, the strips being subsequently assembled to form a matrix. In either case the matrix would be adapted to serve for a column of printed matter.

The key-levers a rock on an axis 1 and are pressed upon by springs a, and to each is piveoted a dtent 2, guided by a slot in aframe 3, pivoted at 4 and pressed against a stop 5, so that when a detent 2 is raised the corresponding small or lower-case letter will be set. To the ends of the frame 3 are-connected two sets of toggle-links 6 6, one link of each set being fast on a shaft 7, so that they work in unison. To the joint 8 of one set is coupled the lever 9 of the capital or shift key S, whereby the frame 3 and detents 2 may be swung forward, so that when a detent is now raised its position will correspond to the setting of a capital letter, the small letters and corresponding capitals alternating on the type-disks. The key-lever 9 is pressed upon by a spring similar to the springs a, whereby the frame 3 is normally held against the stop 5.

The barrel B is loose on shaft 0 and is geared therewith through friction-gear reversible by means of a clutch 10, splined on a sleeve 12, fast with the barrel, the clutch 10 being controlled by a lever 18 and being capable of frictional engagement with either of two cones 13 14, fast with bevel-wheels 15 16, the one, 15, loose on sleeve 12 and the one, 16, fast on shaft 0, both 15 and 16 gearing with a wheel 17, so that the barrel will be rotated in the one or other direction. The barrel B is geared by equal spur-wheels 19 20 with the shaft E, and the disks D are loose on a sleeve 23, having a disk 24, between which and a disk the disks D are confined. The sleeve 23 turns with shaft E, but is slidable thereon for removal of the set of type-wheels.

The type-disks are successively brought to and left in composed position by a spline 21, received in keyways in the disks D in sleeve 23 and in wheel 20. The spline 21 is permanently in driving connection with barrel B, but is slidable longitudinally by a collar 26, loose on shaft E and coupled with a collar 27, fast on the boss 28 of arm 29 on a sliding carriage 30. The spline 21 and sleeve 23 are thus revolved by barrel B to successive angular extents and carry around with them as many of the disks D as are traversed by the spline. The spline 21 is cross-pinned to the collar 26, (as shown at the upper part of the latter in Fig. 2 and upon the threaded periphery of collar 26 is screwed a couplingsocket 26, having an internal shoulder 26, which engages the corresponding external shoulder of the collar 27.

The retraction of the spline 21 from successive disks D is efiected by mechanism brought into action by a feed-key F. The boss 28 and the carriage 30 can slide the one along the shaft E and the other upon guide-rods 31. A dog 32 on arm 29 is engaged by a spring 33 with a screw G on a sleeve g, loose on shaft E, but prevented from sliding, the pitch of the screw corresponding to the thickness of the hubs of disks D, (which is equal to the width of the widest type-body,) so that at each revolution of the sleeve 9 the spline will be retracted and leave a disk D in the angular position to which it has been brought.

The rotation of those disks D which are engaged by the spline 21 and the disengagement of the spline from successive disks occuralternately, the first when akeyAis actuated and the last when the screw G receives one revolution. This is effected through mechanism comprising a spur-wheel 34 on shaft 0 in gear, through wheels 35 36, with a wheel 37, fast on sleeve 9 and mutilated so that the sleeve will remain at rest when the mutilation meets the wheel 36. The mutilated wheel 37 is caused to gear with wheel 36 by a pawl 38, pressed by a spring 41 and pivoted on a link 39, loose on shaft E and coupled by link with the feed-key F. On actuating key F the pawl 38 turns wheel 37 until it gears with wheel 36, whereupon the screw G receives one revolution, and the spline 21 is Withdrawn from one disk D, and so on in succession. The disks D, after being adjusted, are retained by a bar 42,which follows up the retraction of the spline and engages between the arms of the disks D in succession. This retaining-bar is fixed to a frame 44 and passes through a guide-hole in the disk 25, which is fast on a sleeve 45, loose on shaft E, while the frame 44 can slide along the sleeve 45, but turns therewith, the frame 44 and bar 42 moving with the carriage 30, whereof a forked arm 46 engages in the grooved boss of frame 44.

The disk 25 and frame 44 are normally retained by a spring-jointed lever 48, mounted on the sleeve 45 and engaging bya nose 47 in a hole in the machine-frame. To bring the com posed line toimpression position, the nose 47 is disengaged, and the disk 25, frame 44, and disks D are rotated by lever 48 as a handle, so as to bring the composed line of type face downward. Simultaneously with this movement justification is effected by (preferably three) rods 49, mounted in frame 44, and advanced concurrently with bar 42, the rods passing through revolving guide-bushes in disk 25, through clearance-holes in the typebodies cl and space-blocks 60, and through justification-screws 50, screwing in tapped holes in the space-blocks 51. These rods 49 are adapted to make rotative connection with corresponding holes in the justification-screws 50, the rods being tapered at the ends, so as to enter freely. The rods 49 are revoluble simultaneously, each about its own axis, by planet-pinions 53, fast on the rods 49, journaled in the frame 44 and gearing with a sunwheel 51, loose on em 44. A bar em whereby the screws 50 are rotated and screwed out from the space-blocks 51 until by the thrust of the screws 50 the line is completely justified, as indicated in Figs. 10 and 11, which show a longitudinal section and a plan of part of several disks.

Each disk D has a spring-pawl 61, and the sleeve 23 has a longitudinal groove 62 to engage therewith, so that the sleeve 23 can revolve in the one direction, while the disksD are retained by the bar 42; but when the bar 42 is withdrawn and the sleeve 23 is rotated in the other direction the disks D will be carried round with the sleeve and returned to normal alinement. This reversal of the sleeve is edected by the clutch 10 after the impression has been taken. To enable the bar 42 to be withdrawn, the forked arm 46 of carriage 30 is pivoted at 63 and engaged with the grooved boss of frame 44 by a spring-bolt 64, which by yielding allows the arm 46 to be swung back, as dotted in Fig. 5, to allow of the frame 44 being slid back.' The return of the spline 21 is delayed until the disks D have been returned to normal alinement by disengaging the dog 32 from the screw Gby means of a thumb-lever 66, after which the carriage 30 can he slid back to cause the spline 21 to again engage the disksD.

The normal alinement of the disks by the groove 62 is insured by a stationary brush 67 on a frame 68, which both cleans the types and prevents rotation of disks D by mere friction of the sleeve 23.

To permit the replacement of the set of typedisks D by another set, the end bearing 69 for the shaft E is removable,.as shown in Figs. 1 and 2.

To avoid a space at the end of the line when the last word is not divisible at or does not end at the last disk of the set, the superfin-' creased to an extent equal to one, two, or three disks D beyond the length of the line.

In justifying the superfluous disk or disks will be moved beyond the end of the line and if adjusted to present a space-block will yield no impression.

To compose a blank, the key X, correspondbars, being mutually separable.

ingto the plainspace-bloeks 60, may be re"- tained by a latch 81, pivoted at 82 and engaging by a nose 83 with the key-lever so, so that by repeatedly operating the feed-key F the spline 21 will be retracted without rotation of the disks D, and a succession of spaceblocks 60 will be left in the composed position.

The carriage H for the matrix K slides upon the side members 90 of a frame in which revolve two'pairs of eccentrics 91, fast on shafts 92 93, whereby up-and-down motion is imparted to the frame. 'To insure true vertical motion, the carriage H is engaged by a vertically-guided detent 94, which acts also asa pawl cooperatin g with the carriage-feed mechanism. The shafts 92 93 may be geared together by an endless chain, but are preferably coupled by rods working in quadrature, the one red, 95, being coupled to cranks 96,

set at right angles to the radius of the eccentries 91, and the other coupling-rod being formed by the side members 90, in which the eccentrics turn. The matrix-raising mechanism is set in motion by the impression-key I, acting through a spring-pawl 97, pivoted at 98 to the lever of key I and engaging with an arm 99, fast on the end of the shaft 92, whereby shafts 92 and 93 will be turned sufficiently to put a mutilated spur-wheel 100, fast on the latter, into gear with one of a se ries of wheels 101 102, in gear with a wheel 103, fast on the shaft C. After a complete revolution of shafts 92 93 the wheel will go out of gear and so remain until key I is again actuated.

The matrix is fed line by line by a pawl 106, pressed by a spring 107 into engagement with rank 105 at the u'nder side of the carriage H, having teeth corresponding in pitch to the distance between successive line impressions,

this rack being also engaged by the detent 94. The feed-pawl 106 is pivoted on an ec centric or crank on shaft 93, so as to receive to-and-fro motion, the driving stroke occurring while the matrix-carrier is lowered.

The carriage is pulled rearward by a cord 108 and spring-barrel 109, whereby the carriage after reaching the end of its course may bequickly returned to initial position, with a fresh matrix operating a key M. The detent 94 moves in guides 110 and is forced toward the rack 105 by a spring 111 on the feedpawl 106, and the lever 112 of key M engages by a lug 113 with a lever 114, pivoted at 115 and connected to a swing-bar 116, which bears upon the tail end of the pawl 94 and upon a lug on the feed-pawl 106 in order that the pawls 94 and 106 may be disengaged simultaneously, leaving the carriage free to be returned by the spring-barrel 109.

Upon the plate h of carriage H fitsaframe 117, wherein fits a grid, whereof alternate bars 7c are'attached to its opposite sides118 119, these sides, with their respective sets of The plastic strips K rest upon the plate hand fit between the bars 7:; and are removable as a whole along with the frame 117 and the grid. The strips are'exposed in the grid to the air at top and bottom to dry, whereupon the parts of the frame may be separated to release the strips, which are then assembled to form a matrix.

Figs. 7, S, and 9 show radially-protractible types and the means of protraction. Fig. 7 shows a face View of part of a disk, and Fig. 8 shows fivejuxtaposed disks in section through the composed line of type, of which three are in protracted position. Each type-body d has a shank 120 grooved to slide upon the radial arm 121 of dovetailed section, Fig. 9, and is normally retracted by spring action, two springs 122 and 123 of annular form being preferably employed, lying in cross-notches 124 in the shanks 120, the one spring 122 bearing against a shoulder 126 on every alternate type-body of the disk, while spring 123 bears against a shoulder 127 on every intermediate type-body. This division of the type-bodies into alternating series insures that when a type-body is protracted the adjacent type-bodies shall not also be protracted. The composed line of type is protracted by a cam-bar 130, mounted on frame 44 and advanced along with the bar 42. Each typebody 61 has a slot 131', through which the cambar 130 passes, the end 132 of the cam-bar being beveled, so as on meeting the bevel at the ends of the slots 131 to cause the type-bodies to be protracted beyond the normal radius of the disk. To permit of this movement, the holes through which the justification-rods 49 pass are elongated. The space -blocks would be fixed and have slots long enough to allow the cam-bar to pass freely through.

We claim-- 1. In a type-com posing and matrix-impressing machine, the combination of a plurality of type-disks each having radial, laterallyflexible type-body-carrying arms, the disks being closely juxtaposed and independently revoluble upon a revoluble sleeve, and being provided with pawls adapted to engage with the sleeve when turned in one direction so as to cause the disks to be brought to position of initial alinement, as described.
