The invention relates to printing machines, and more particularly to a machine including therein a plurality of type carrying members,

and means by which succeeding lines of type may be set up, an imprint may be made following the setting of each line of type, and the types from v which imprints have been made, may bedistributed preparatory to the setting up of a succeeding line.

In a machine embodying the invention, the various type carrying members of the printing couple are equipped with a complete fount of type,-and means are. provided whereby diilerent letters and characters may be successively it brought into alinement in the printing position in relation to a platen, andfollowlng the setting up of each line, the words may be spaced and the line justified prior to the making of an imprint therewith.

W The word spacing and line justifying mechanism embodies therein selectively operative 7 means carried by the several type carrying members, each of'these individual mechanisms being capable of being set when type has been set for each word, all of such mechanisms remaining inoperative until a whole line has been set, whereupon the mechanisms so set may all be actuated from a single source of power. soas to impart movement to all type carrying members the line, and bring the letter or character at the right hand end of the line-into a position where it will, in the imprint, be in true vertical allnement with the corresponding-characters of other line justifying mechanism of the invention, a corresponding margin is secured at eac 'eflect as'with ordinary printing.

.The construction and operation of the word spacing and line justifying mechanism is such that in the event of variation in the number of necessary to effect a spacing of all of thewords in lines. In other words, by. the word spacing and end of every line, thus securing an accurate column words, or the number of lettersin a line, or both,

the spacing between words will be automatically variedso as to equalize the movement of the various type carrying members in a manner to distribute the aggregate movement of all type carrying members amongst the spaces between different words,

The type carrying mmb'ersare' so constructed and arranged that they may be individually and has been actuated, will be locked in a set position, succeeding printing characters beingbrought by 55 the type setting mechanism into substantial successively actuated, and each member, after it with the said types.

alinement with characters previously set, and

held against movement when setting succeeding characters, by this locking mechanism. The construction must be such that the setting member operative upon the type carrying members will be disengaged from each such member after each character has been properly set, in order to permit a proper progression in the setting up of t p In connection with the type setting mechanism, 10- I provide a proofing mechanism by means of which an impression is made of each character as it is set, so that preparatory to'the actuation of the word spacing and the line justifying mach: anlsm, the operator may determinewhether or not the proper characters have been set up. This proofing mechanism is actuated simultaneously with, arid by the same mechanism used for, actuation of the setting and locking mechanisms, and following the setting of a character upon each type carrying member.

.The construction of the machine is such that when each line has been set up, and justifled, and the type carrying members locked, an impression is made of that line, the printing operation being of the type known as bed and platen printing in which an impression platen is moved by a powerful mechanism into and out of engagement I Ordinarily, this impres-* sion is an ink impression upon a. sheet of paper, an inking mechanism being provided in the machinewhich is actuated by the platen operating mechanism in a manner to ensure a proper timing in the inking of the types'and the making of an impression. The particular inking mechanism shown is (16-. scribed in my co-pnding application, Serial No. 146,175, filed June 3rd, 1937. desired, however, stencil sheets may be used, in'which case the application of ink to the types is not required. 40

Whether the machineis used for making an ink impression upon paper or for cutting a stencil, .itis essential to provide a sheet feeding mechanism in operative relation to the printing platen, l

and to so'actuate this mechanism as a result of 4cthe movements of the platen carrying member, as to secure-arr automatic feeding of the sheet and a proper spacing of succeeding lines' upon the paper or stencil sheet. This feeding mechanism is so constructed as to permit great nicety anisms for the various type carrying members, I preferably provide a supplemental locking and alining bar actuated by the platen mechanism immediately prior to, and during the making of an impression.

Following the making of each impression, it is necessary to distribute the printing characters or types. To permit this, it is essential that the setting, and the locking and alinement members be made inoperative as to each of said type carrying members, and that means be provided whereby a differential movement may be imparted to each type carrying member to restore it to a normal or zero position, so that when setting up the next line of type, each type carrying member will occupy the same relation to the type setting mechanism as when setting up every other line.

The construction of this .distributing mechanism is such that it may be brought into the operative relation to all of the type carrying members, so that finally, by a single continuing movement, all of these members will be brought into the desired position, with similar printing characters upon all of said members in alinement. This is essential because the same actuating mechanism and an associated index is used for setting each type carrying member, and the extent of movement of each member to set up a given character must be the same as that of every other member in setting up the same character.

The machine may also include type cleaning rollers which may be brought into or out ofthe operative relation to the printing characters to facilitate the cleaning of thetypes.

The machine of the invention is designed to provide an original imprint, whether in ink or upon a stencllsheet, which may be used for reproduction purposes. If an inked impression is made, a printing plate is made from the sheet by ordinary photo-engraving methods with a suitable reduction to secure a desired sharpness of linesand strength of impression'from the photo-engraved plate. The machine ordinarily would be used in making an original for the production of such photo-engraved plates, oversized types being used to facilitate photographic reduction in the manner above referred to.

The construction of the machine is such as to permit accuracy in the setting up of the printed matter, rather than speed. All of the mechanisms are so constructed and arranged that in the event of error in setting up the printing characters, such error may be detected from the proof strip prior to the making of an'impression, so that correction can be made or the line entirely re-set.

In the embodiment of the invention shown in the drawings, a sequence of discs, each carrying a full fount of printing characters, is mounted upon the same shaft, and the setting of the .printing characters and the setting and actudisconnection from, the alining and locking bar so as to ensure the proper alining and locking of successive type carrying members as they are set, while permitting the disengagement of this locking bar from said members during the distributing operation. I

The various mechanisms in the machine are so designed and so combined as to not onlyensure certainty and reliability in the operation of these mechanisms to reduce error in the operation of the machine to a minimum, but these mechanisms are few in number and, conveniently accessible to the operator so as to permit the operation of the machine at moderate speeds.

The invention consists primarily in a printing machine embodying therein the novel features of construction and combination of parts hereinafter set forth and described, and more particularly pointed out in'the claims hereto appended.

I in describing the various mechanisms of the machine, these mechanisms will be considered in the order of the sequence of operations, of the machine, as follows: the type carrying members and the. setting mechanism operative thereon; the word spacing and line justifying mechanism; the proofing mechanism; the printing mecha- The shaft 32 is turned by means of a setting wheel 33 having about the periphery thereof, printing characters 40 corresponding with those upon the various type carrying members, there being associated with this wheel, an index finger 4| by means of which accuracy in the movement of the wheel to bring the desired character in the printing position, may be secured. The position of the index characters 40 upon said wheel 33 is approximately 180 offset in relation to the corresponding. characters upon the verai discs 33. The edge of the hand wheel 39f provided with a sequence of notches 42 with which a lock member 43 is adapted to co-operate following the set-- ting of each disc.

The setting bar at is carried by a sleeve slidably mounted upon the shaft 32 and capable of a step by step movement along this shaft as the setting of the various type carrying members nism; the distributing mechanism, and the type progresses. This sleeve M carries a ratchet tooth a!) cleaning attachment. Various actuating parts in the machine, as shown in the accompanying drawings, are common to .difierent mechanisms, and the movements of difierent parts will vary according to the mechanisms, the. operative effect of which is controlled at different times during the setting up and distributing of a line of type.

Mounted in suitable bearings and spaced from the bed ti of the machine is a main actuating shaft 32, having idly mounted thereon a plurality of type carrying members 33, each of which, in the embodiment of the invention shown in the drawings, consists of a disc idly mounted upon the shaft 32'and having, about the periphmember 45 by which the sleeve and the bar may be advanced by a reciprocatory ratchet bar 46, spring pressed by a plunger 4'! into engagement with the ratchet tooth member 45. This spring plunger support for the ratchet bar 4d 35 permits'the teeth of this bar to ride over the teeth of the fixed pawl during itsreturn movement following each feeding movement of thesleeve 4t. The ratchet -bar 66 has, in the side thereof, a

groove 48 in which is seated a crank pin 49 cars go ried by a shaft 53 having a knurled head, so that when restoring the setting bar 36 to its operative relation to all of the discs 33, saidbar may be. disconnected from the member 45. This return ery thereof, raised platens having engraved, m m nt 1 the Sleeve nd S ill is by means 3 rolled or otherwise'impressed thereon, upper and of a cord 5i passing about guide pulleys 52 and lower case printing letters, numerals, punctua- .53 and about an actuating sheave havinsa separation in word spacing and in line justifying,

by mechanisms carried by the various discs, which will be described in connectionwith the word spacing and line justifying mechanisms in the machine. s I

Each disc has a central bearing opening en.- gaging the shaft 32, and'extending outwardly of this hearing opening is a keyway 34 bynieans of which the disc may be turned when setting the type. l

The main shaft 32 is provided with a sequence of longitudinally extending keyways 35, in one ofwhich is slidably mounted setting bar 33, high part 3! of which is ad pted to. enterthe keyways 34 of the several discs 33, and a low part 38 of which is of a height to be flushwith the surface of the shaft 32. In this manner; the setting bar may be progressively disengaged from the sequence of discs 33 so as to permit the progressive setting of different type carrying members. In other words. the setting bar 36 is adapted to be selectively and progressively engaged with, and disengaged from, the various type carrying members so as to impart movement thereto with the turning of the shaft 32, or to permit turning of said shaft without imparting crank handle 55, the opposite ends of this pull A cord being connected at opposite faces of the sleeve 44.

The sleeve 44 merely slides along the shaft 3%,

this shaft and the setting bar 38 having turning movement in said sleeve. To secure this result, I provide the sleeve 44 with a bearing collar lit, the angular end of the setting bar 36 being sec'uredto this hearing, as indicated at 31 in Fig. 4 01 the drawings. v

Since the low part 38 of the bar 36 is flush with the surface 'of theshaft 32, said shaft, the collar 56 and the portion 33, of the setting bar may tum. freely inrelation to the sleeve 44. v

Mounted in a suitable bearing 58 is a shaft I3, Fig-2, actuated by'n crank handle 83. This shaft 53 carries an eccentric pin 6| seated in apocket .82 adjacent one end of the ratchet bar 43. By turning the shaft 53 alternately. in clockwise and contra-clockwise directions, said bar 46 will be reciprocated to advance the sleeve-- 44 and the setting bar mainshaft 'fl. I Mounted in suitable guides tflsa locking and ,alining bar 84 adapted to enter the spaces between the platens upon the several type carrying members 33. Said guides ii-arecarried by the top plate of. the-machine directly -below the vertical center of the shaft 32 and' of the-various discs 33 mounted thereon. v

While the high part 31 of the setting bar: 38' is normally engagedwith discs 33 which have -36 longitudinally of the movement to type carrying members already set. the shaft 32, the setting bar is disengaged froni ls each disc after it has been set, and the bar 84 receives movement with said sleeve so as to engage those discs from which the setting bar 36 is disengaged, simultaneously with the disengagement of said bar therefrom.

It is essential, however, during the distributing operation, that both bars a and M be disengaged from the discs.

To secure the above desired mode of operation, the sleeve '44 is detachably connected with the bar 64 by means of a pendent ing 65 carrying a latch member 66 engageable in a keeper slot 61 upon said bar 64. The shaft 50, as shown in Fig. 14,-is mounted in this lug, and the latch member 66 is spring pressed into engagement with the locking and alining bar. Said bar it is provided with a finger grip 68 by which 1ongitudinal movement may be impartedto this bar when the latch member 68 is disengaged therefrom.

A machine embodying the invention is used for setting one line of type of a predetermined length, at a, time, and making an impression from that line of type prior to the distribution of such type and the setting up of succeeding lines in the same position as the previous line.-

In hand or machine setting of type, or matrices from which a line of type may be cast, quads or other word spacers are used when setting up the type or injustifying the line, so as to have all lines of exactly the same length. Quads and other spacers -are alsogused in correcting errors in hand setting up of type, and-in justifying lines of type when so corrected. Conforming the set upof type to a corrected proof and rejustifyin'g lines is a time'consuming procedure, and in some instances may require the re-setting, of several lines of type where wordshave to be omitted, added, shortened or lengthened.

The machine of the invention sets only one line of type at a time, so that in the event of machine after a line has been completly set up.

During the setting of a line of type, a word spacing and line justifying mechanism may be set, preparatory to its actuation. and following the setting of the last type carrying member of a word, and the various spacing and line justifying mechanisms so set are simultaneously actuated when the line has beerf completely set, so as to impart movement to all type carry-, ing members longitudinally of the shaft 32 to an extent to bring the last letter of the line to the extreme right of a column impression. The amount of movement .of the various type carryingmembers will differ in lines having a different number of letters or a different number of words, butthe word spacing and line-justifying mechanism will automatically distribute the maximum available movement throughout the spaces between the words by varying the'quan tity of movement of the type characters.v

To secure the above mode of operation, each of the type carrying members 33 has a recessed portion 9 in one face thereof, about which are a plurality of guide clips II, by means of which shaft 82.

About the outer periphery of the pawl ring Jacent guide clip III. A' second double acting cam 13 is acted-upon by a spring 'ILto hold the pawl ring ll oil-center in relation to the shaft 32 and engage the cam surfaces 12 with said clip ll. This pawl ring also carries a stop ll limiting the turning movement of the ring by engagement with one or the other of two adjacent guide clips 'II.. This pawl ring also has a recess 16 through which the setting bar 36 passes, the high part 31 of said bar being adapted to engage the walls of said recess. The ring II is adapted to be turned by the main shaft 32- "II is a cam surface 12, engageable with the ad-" through the application of power from'this shaft to oppositely set pawls 1|'l8 carried upon said ring 'll, the pawls 1I'|8 and the spring arms 82 are all within the plane of the face of the disc having the recessed portion 69, so that the adjacent discs can be brought intov closely abutting relation, as'shown moreiparticularly in Figs. '8 and 9 ofrthe drawings. The shoes 8i are of a thickness to separate adjacent discs as they slide along the cam surfaces II with turning movement of the ring H.

The spring ll, with a normal setting of "the ring ll, holds this ring off-center in relation to the shaft 82 with the pawls ll-I8 out of engaging relation with 'said shaft. If said pawl.

ring ll be turned very slightly in a clockwise direction, as shown in dotted lines in Fig. 10, the cam-surface l2, byengagement with its cooperating guide clip, will impart movement to the ring 'll substantially radially of the shaft 32, so as to permit the spring I! to act to engage the pawls '|'|'Il with the periphery of the As heretofore stated, this shaft has a plurality of longitudinally extending grooves along the portion thereof upon which the various type carrying members are mounted, which grooves extend to the extreme right hand end of the these grooves withthe turning of the ring H inthe manner indicated, 1' provide a plurality of filler bars 83 slidably mounted in said grooves, which filler bars will be engaged by the pawls ll-18 with the turning of the pawl ring 'll Said filler bars are carried by a head M to which is connected a rack bar 85, saidrack bar and said head being connected by a swivelling fitting 86, as shown more particularly in Fig. 6 of the drawings. A I v Y Carried by the bed of the machine is a bracket 81 (see Fig. 2) in which is mounted a shaft ll carrying a gear wheel 89 enmeshed with the spacing and justifying 'rack bar 85. The shaft II has a hand crank ll.

The various discs 33 are positioned between 'headers Ii and 02, both of which are idly mounted upon the shaft 32. The header has no movement along the shaft .32, but the header 02 is slidabie along said shaft and carries'a pin-o rallty of stop rods 83 engageabie with a stop member 94 adiustably mounted upon the bracket 81. This bracket is adjustable toward and from that the high part 31 of the setting bar 36 be Elli lib

brought successively into engagement with the keyway 3d of each disc 33 to be set and then moved out oiengagement with said keyway and into a position where. it may be engaged with the shoulders of the recess It, so that the shaft it may be turned after the type carrying member has been properly set to actuate the ring ll without disturbing the setting of the discs, til. In other words, a two-step movement is imparted to the setting "bar 38 following the setting of one type carrying member, and preceding the setting of the next adjacent type carrying member. Consequently, since all movement of the setting bar results from an actuation of the rack bar it by movement of the crank handle til, it is necessary to give said handle two direct and return impulses after a type carrying member has been set and, upon the completion of the setting of each word, to turn the shaft ll to set the ,pawls llill alter the first complete direct and return impulse of said handle, or between the impulses of said handle.

The stop member all is mounted in suitable guides lit upon the bracket ti, and is provided with a lock screw til by which the stop may be set in any adjusted position. I

The outside diameter of the ring ii is considerably smaller than the diameter of the recess in the disc, and the inside diameter of said ring is larger than the-diameter of the shaft ill and is provided with recesses for the accommodation of the pawls ll-l8 and for a stop member ll formed upon the disc 33 for limiting the first stage of movementof the disc by the setting bar It is also provided with a curved enlargement it which, during the final stages in the turning of the ring, when the spreading heads ll are operative, will engage the shaft32. These,

however, are mere matters of design necessary to permit the combined turning and radial movement of the rings as they are operated to set the pawls llll.

As heretofore pointed out, one line of type-at a time is set up, and after an impression has been made therefrom, the type is distributed. Consequently, there is no standing type from which a proof can be pulled, and any typographical errors in setting up a line must be detected before the imprint ismade from that line if the type in printing a sheet may be inspected prior to the making of an impression irom that line and, if necessary, the

whole line or a part thereof may be re-set to ator may avoid error in the final set up and avoid much of that expense and delay which occurs in ordinary typographical work in cor-- 9,145,a71 I recting proofs and conforming the set up to the corrected proof; I

In the actuation of the proofing mechanism, some of the mechanisms used in setting the various type carrying members or discs 33 are uti-.

lized, thus ensuring accuracy in the operation 'of the proofing mechanism aswell as a proper timing inthe actuation of the same in relation to the setting mechanism. The proofing mechanism, as shown in detail in the accompanying drawings, consists of a guide 99 positioned adjacent the periphery of the setting wheel 3%. 1 I

In addition to the printing characters dd about the'wheel it is a second set of printing characters int, odset in their arrangement in relation to the characters M, and '50 positioned in sequence that each printing character is brought into the printing position, a corresponding printing character will be positioned adjacent an opening lill through the guide Qt. A proofing tape consisting at a carbon coated strip llll is -llld,;.and the other arm of which is in the form of a cam i it. Acting upon this lever is a spring lll having a normal tendency to force the hammer'ltiil toward the opening ldl in the guide til. The shaft lit receives intermittent rotation from a ratchet wheel ill acted upon by a star wheel lit carried by and rotatable with a ratchet wheel ill, the ratchet wheel having, in the form of the invention shown, six teeth, while the star wheel lit has three arms.

Carried by the crank arm ht is a pawl lib which, with oscillation of said am lid, is engaged by a spring ill with one of the teeth of the ratchet wheel ill. Said ratchet wheel lid receive one-sixth of a revolution with each downward movement of the crank handle dd, during which the star wheel. i it will actuate the shaft ltt in a manner to impart feeding movement to the proof tapm ltd and ill by'one arm of'this wheel, and the succeeding arm of this wheel will act upon the cam lid in a manner to move the hammer ltd away from the all arm Bil, the hammer will be released while the tapes it'll and Ill are at rest, thus permitting the spring ill to violently project the hammer into engagement with the tape ill and cause the making of an impression thereon in the mani ner indicated in Fig. 21 of the drawings. a detent spring ll'l acts upon the ratchet wheel ill.

Th part of this shaft carrying the eccentric pin 8| has mounted thereon a sleeve II8 carrying the crank handle 60 and acted upon by a torsion restoring spring II9. This sleeve carries a cam I acting upon the locking tooth 43 engaging the teeth" upon the setting wheel 39. A spring I2I. acts to normally disengage the tooth 43 from the teeth 42. The pin and slot lost motion connection is shown at I22.

A roll of proofing strip I02I03 is carried by a suitable reel I23 mounted adiace nhthe guide 99.

By the described construction of the shaft 59-I I8, the shaft 32 is locked against movement prior to any movement of the setting bar 36, and the setting wheel 39 is held against possible accidental movement until'after actuation of the proofing hammer.

' stencil sheet as heretofore described. These lines are accumulated upon this sheet until a printed page of the desired size has been produced, whereupon 'the completed sheet of paper is removed from the machine and a new sheet of paper is mounted in relation to the printing mechanism. The printing mechanism must therefore include not only an impression platen, but a cylinder adjacent said platen for supporting and feeding a sheet of paper in relation thereto, and means for imparting a step by step feeding movement to the cylinder following each actuation of the platen to cause a proper spacing between succeeding lines impressed upon the sheet.

In conjunction with said platen and said paper supporting and feeding mechanism, I provide means whereby the amount of feeding movement of the sheet may be varied to secure different bed of the machine at I29. Mounted in said lever is a .paper roller I30 having two clamp bars I3I and I32 adapted to engage the top and the bottom of the sheet respectively.

The cylinder I30 is loosely mounted upon a shaft I33 and has secured thereto a ratchet wheel I34. Also loosely mounted upon said shaft I33 is a swing frame I35 carrying a plurality of pawls I36 engageable with the ratchet wheel I34.

Carried by the hub of the three armedlever is an arm I31 having a spring I38 connected with the swing frame I35 so as to impart movement to this frame during the interval that the platen I26 is being advanced into engagement with the type from which an impression is to be made.v

The swing frame I35 has one arm I 39 provided with a stop screw engageable'with the shaft I29 to limit oscillation of said frame in one direction, and with a secondarm I40 carrying an antifrlction roller I4I engageable with a cam I42 adjustably mounted upon suitable-'guideways I43 -catory framecarrying the inking mechanism paper cylinder I 30. Each pawl is provided with upon the bed of the machine. This cam I42 is adjustable along said guides by a lead screw I44. and a lock screw I45 is provided for securing the cam in any adjusted position. A gauge cylinder I46 is carried by the lead screw I44, and adjacent 5 this gauge cylinder is an index finger I41 by means of which the extent of adjustment of the cam I42 may be determined with reasonable accuracy.

By means of the lead screw I44, the cam I42 may be advanced towards the bearing I29 to increase the spacing between succeeding impressions of lines of printed matter. By withdrawing said cam from said bearing, the spacing between the lines may be reduced.

The actuating means for the platen I26, the paper feed cylinder I30 and its appurtenances, and the paper feed mechanism consists of a shaft I48 having an elongated operating lever I 49. Said shaft I48 has two short arms I50, each of which is connected with a third arm I 5I of the lever carrying the platen. The shaft I48 carries a counterweight I52. The operating lever I49 extends to adjacent the front of the machine and has a handle grip I53.

The shaft I48 is positioned rearwardly of the machine. There is one short arm'I50 at each side of the machine, and there is one three armed lever I 2'!I28I5I at each side of the machine so as to properly support both ends of the impression platen.

' By the construction above described, a sort of toggle lever connection is provided between the operating lever I49 and the platen bar I26, thus ensuring a desired high pressure relation between the platen and the types from which an impression is being made.

When the types are to be inked prior to the making of the impression, an inking mechanism I54 and its actuating mechanism I55 is employed, 7

but a detailed description of this mechanism is 40 unnecessary since it is described in detail in my copending application above referred to.

Broadly, as hereinafter stated, this inking mechanism includes therein a vertically reciproproper, and an actuating mechanism operative thereon for imparting one complete reciprocatory movement thereto with each actuation of the movable member of the printing couple and prior to the making of each impression, connections between said actuating mechanism and the means for imparting relative movement to the members of the printing couple being provided, said connections including thereinmeans whereby said inking mechanism is brought into and out of the operative relation to the types during the movement of the platen toward said types.

Three pawls I36 are used to ensure accuracy in the initial and full turning movement of the a heel I56 engageable'by a stop I51 upon a slide I53 carried by the swing frame I35, so that all .of these pawls may be made inoperative in relation -to the ratchet wheel I34 when the cylinder I30is turned while placing a sheet of paper upon the cylinder. Set screws I59 are used to lock the slide in its inoperative position, the central screw I59 being used to actuate the slide,I58.

-In conjunction. with the printing mechanism,

it is desirable to. use a locking and alining bar 7 machine, extending between which is an alining and locking bar lGl movable in the .forkedends of the brackets I60 radially of the various type carrying members 33 and engageable with the space between the platens carrying the types. This bar |6| carries rods I62 mounted in lugs Hi3 upon the brackets I60. Said bar is acted upon by springs I64 acting between the bar and the lugs I63 to normally hold said bar out of engaging relation with the various members. r

'Carried by the opposite arms l2! are hooked spring members l65 which, with movement of the platen I26 toward the members 33, engage the gagement oi the hooked portion thereof from said bar ltl, so as to avoid the removal of the bar from said brackets llit. v I

While means restraining outward movement of the bar it! may be employed, this is not neces sary if springs lt l of light tension be used.

After an impression of eachline has been-made, it is necessary to distribute the type preparatory to the setting of the succeeding line. The distributing mechanism shown in the accompanying drawings is adapted for use in a machine in which the type carrying members consist of discs having spacedperipheral platens which are set by a rotary movement of the discs. 1

While, during the setting of the discs, it is unnecessary to restore the setting mechanism to the same position each time a disc isset, it is essential, in distributing the types, that all-of the discs be brought into a corresponding zero position preparatory to the turning of the first disc in setting a line of type, since the setting bar 86 must be engaged with the various discs, and to so engage this bar, the slots or keyways all in the various discs must be brought into alinement to permit movement oi the bar it.

In distributing the type, it is essential that each disc ti receive movementcomplementing that which is received in setting the type thereon to restore that disc to its normal zero position.

Since different discs are turned a diflerent number oi'degrees in setting, it is obviousthat in distributing the type difierent discs'must receive a correspondingly difierent degree of movement to bring themto the zero position.

The distributing mechanism shown in the drawings is so constructed as to pro'gressively pick up the difierent discs according to their setting, and by a single continuing movement to restore, with one revolution 01 this-distributing mechanism, all, of the discs to the desired zero position.

To secure this result, llprovide each of the discs with a long tooth I66 projecting beyond the type carrying platens. No printing characters are usedadjacen't this long tooth since the presence appearinghin the printing line, throughout the circumference of thegroupoi discs. in the man I ner shownin Fig. 25 of the drawings; p

Under normal conditions the baivlfi'l is retracted in relation to. the various type carrying members so as to be'out oi the path of movement of. the high teeth ltd, thus permitting a free turning movement of said members 33 when the distributing mechanism is set in the neutral position.

Extending from the 'header 9|! to a disc 6W3 idly mounted on the shaft 32, is' a bar l'lii spaced froin the discs 33 by blocks lit. Rotatably mounted on said bar H5 is a rod llli, carrying a distributing plate l'lt having a toe portion lit and an angularly projecting heel portion Edit. This plate is oil a length to co-opei'ate with all type carrying discs it.

As will more fully appear hereinafter, when. setting the distributing mechanism immediately .prior to its operation, the plate lid is rocked by means of the crank iii to bring the heel ltd to a position, as shown in Fig. 25, where it will be in engaging relation with the teeth ltd. A;

After such shortreciprocation, the

crank l8l is moved toward the axis of the shaft it, past the opening I83, into engagement with the opening I85 so as to remove the heel llit out of engaging relation with the high teeth and bring the toe lld into such relation; After the types have been distributed, it is necessary to bring both the heel ,lfld and the toe lltl out of engaging relation with the teeth ltd, which is done by moving-the crank ldi until the spring lock engages the openingit. The function of the pivotal dog I88 is to automatically engage the spring .lock I82 with the opening till with the final retardation of the bar Wt to its normal position, shown in Fig. it. s

This type cleaning mechanism comprises a tank I 33 for type cleaning fluid,having mountedtherein a distributing roller I89 immersed in the fluid in the tank, and a felt cleaning roller'i projecting beyond the open top of the tank in a position where it may be; by oscillation of the support for the tank, brought into or moved out of engaging relation with the types upon the This tank is supported by arms I 9I toward opposite ends of the ,machine, having a dovetail slide I32 permitting removal or partial removal of the tank for cleaning and re-filling purposes. The arms I9I are acted upon by springs I93 having a normal tendency to move the tank I38 in a manner to engage the cleaning roller I90 with the types.

Carried by the tank I83 is a'spring arm I94, the

turned end of which is engageable with a keeper member I95 restraining the action of the springs I93 and holding the roller I83 well away from the:

-The operation of the herein described printing machine is substantially as follows:

In the operation of the machine, the various type carrying members 33, in succession from left to right, are actuated to'set up a line of the desired length. The number of letters in different lines, as well as the number of words in the line," will vary, so that in justifying each line, the spacing' between the words in difierent lines will vary. In setting up the types in a line, the succeeding discs are successively actuated, the setting jacent' words.

mechanism is disconnected from the disc immediately after it has been properly set, and-the disc is locked before the setting mechanismis disconnected therefrom.

Upon the completionbf the setting of each word, the part of the word'spacing and 'the line I Since the .letter or printing character at the extreme right of the line must be brought into exact vertical alinement with. the lastletter o 7 character of all other lines {impressed upon sheet, it is obvious that the operative eflect of the word spacing and the line justifying mechanism must be controlled so' as to secure a movement of the various discs in accordance with the number-of words and number of printing characters in the line The mechanisms used for so controllingthe actuation of .said'word spacing and line justifying mechanism must be adjustable to secure this effect, although by a differential operation of the mechanisms carried by the various type carrying members a part of this variation in the number of letters or the number of word spaces may be distributed throughout the word spaces in the line.

the other.

' During the actuation of the .word spacing and line justifying mechanism, the mechanism operative in turning the various discs is inoperative as to all discs so turned, but each of these discs is locked against rotation. 3

When each line of type has been set, the words spaced and the line justified, an impression of that line of type is/made upon a sheet of paper, or upon a stencil sheet. After the making of the impression it is necessary to restore all of the type carrying members to their (normal neutral made upon a proof sheet, conveniently accessible to the operator of the machine, so that prior to the making of an impression, proof may be read to detect any error in the set up. Proofing of the set up in this manner is of importance in the operation of the machine of the invention, since any error in the set up of any line would require I a reprinting of an entire page.

In a machine embodying the invention, the

procedure is unlike that of any printing method in which a "page impression or galley proof can be made, since the type in each line, after making the impression, is distributed. Consequently,

as stated, any correction must be made, and any error in the set up must be detected, before an impression is made.

The above is a general brief description of the operative effects secured by a machine embodying the invention.

I will now describe in detail the successive operations with relation to the various parts by which each operative effect is secured.

Prior to the first operationin setting up type by means of the discs 33, the parts will be in the position shown more particularly in Fig. 4 of the drawings, the type setting bar .36 occupying its extreme position at the left of said figure with g the high part 31 of this bar seated in the keyways 34 of all of the discs 33 in the machine. The discs 33 are all in close abutting relation, one to The lock bar 64 is disengaged from all of the discs 33, and the latch member 66 is engaged with the slot 61 in said bar 64, so that thetype setting bar 36 is connected with the locking bar 64 in a manner to cause simultaneous movement of both of these bars as the setting of the several discs 33 progresses from left to right of the machine.

The spring plunger 31 acts upon the ratchet bar 36 in a mannerv to engage the teeth of this bar with the member 45 upon the sleeve 44. p

The filler bars '33 are moved to the extreme left in the various keyways 35, so that the main shaft 32 presents a smooth continuous surface throughout, except adjacent the high part 31 of the setting bar 38.

With the various parts in the printing ling, or platens which have no printing characters thereon. If wide spacing between words is required, these non-printing platens may he. used as quads following the lastletter of a word,'and the. word spacing and line justifythe position de- I,

' scribed, there will be a line .of blank platensalong 76 ing mechanism carried thereby may be set. This expedient, however, is resorted to only when the number of letters or other printing characters in a line, and the number of words, are so few as to require excessive spacing. v i

This positioning of the various discs resultsi the high teeth I63 of all of the discs 33 being in alinement adjacent, but out of engaging relation with, the stop bar I01.

The pawl rings II of the various discs 33, and the pawls l1 and I8 of each disc, will be in the positiongshown in full lines in Fig. '7.

The stop 34 is then set so as to be engaged by the stop rods 93 with the s re d n of the discs, so that the last printing character in a line of .type willcome to the extreme right of .a column of the desired width. The setting of this stop will vary according to the number of letters and words in a line, the original setting being merely an approximate setting.

The distributingbar I willbe resting upon the top of the brackets I63 in which the stop bar I6! is mounted. The spring loclrIBZ will be engaged with the opening I83, so that both the heel I 80 and the toe I19, of the plate I18 will be out of the path of movement of the various high teeth I66.

\ If the first letter of a column is to be positioned at the extreme left of a line, as indicated-in Figs.

bar from the keyway 34 and move it into the i recessed portion 69 of the disc being set. With the movement of said sleeve 44,. the alining and 15 and 16, the operator turns the shaft 32 by means of the hand wheel 39 until the character 40, corresponding with the letter to be set, is alined with the index finger 4| In so turning the shaft 32,'all of the discs 33 will be turned, including the disc being set by this turning of the shaft. The sleeve 44 will receive no turning movement with the shaft.

When a letter has been properly set, the operatorturns the shaft 59 in a clockwise direction, Fig. 2, by means of its crank handle 80. This movement of the shaft 59 results in various operative eifects. Through the crank pin 3| it will move the ratchet bar 46 toward the bank of discs 33 which, through the ratchet tooth member 45 will move the sleeve 44 along the shaft 32, thus moving the setting bar 33 a distance suflicient to disengage the high part31-of this locking bar 64 will beadva'nced, in relation to the disc being set, to the same extent as the setting bar 36 is, withdrawn from that disc. The locking and alining bar 34 enters between the platens about the periphery of the type carrying member or disc.

With this initial movement .ofthe shaft to, the

high part 31 of the setting bar 33 is movedoutv of the keyway 34 in the disc,.and simultaneously with this release of the disc in relation to said setting bar, the locking and alining bar will engage the disc so as to hold it against further movement during the setting of the line-of type.

With this initial movement of the shaft 59, the hooked pawl H5 engages and turns the ratchet wheel H4 by the length of one tooth, and the star wheel I I 3 one-halftime distance between the arms of this wheel. Since the crank handle 00 actuates the shaft 59 through the sleeve H8,

having a lost motion connectionbetween same and said shaft, said sleeve H8 will-receive movementprior to the shaft and thus cause the cam I-20 to' actuate the lockmember 43 in a manner to hold the setting wheel 39 against movement ygby the engagement of the tooth of saidlocking member with the teeth 42 about the edge of the said setting wheel. The partial turning of the star wheel H3 turns the ratchet wheel H2 and thus advances the prooftape 102-403 by the feeding rollers I00. This is accomplished by one 01 the teeth of the star wheel H3, the following tooth of this wheel, by engagement with the cam H0, moving the proofing hammer I09 against the tension. of its spring III. v

When turning the setting wheel 39, the printing character I00 corresponding .with the character being set, will be brought opposite the opening .IOI in the guide 99, or in operative relation to the proofing hammer I09.. With the parts in this relation, the crank handle 30 is permitted a return oscillatory movement by the spring II 9, during the final stages of which the shaft 59 will be turned to impart'a return movement to the ratchet bar 46 without, however, any

return movement of the sleeve Mfsince the ratchet ,bar 46 will be depressed during this return 'movement against the tension of the spring pressed plunger 41 in riding over the teeth of the ratchet tooth member 45.

The locking member 43 is used to prevent accidental turning of the setting wheel 39 since, while the type carrying member already set is locked against movement of the locking and alining bar 64, the shaft 32 and said wheel 39 carried thereby are not so locked.

If the type thus brought into the printing line is only one letter of a word and not the last letter thereof, the crank handle 30 is then again 'with the cam arm I I0 during the first movement of the shaft 59, is moved out of such engagement During this second movement of the crank handle' 60, the arm of the star wheel H3 engaged and brought into the operative relation to the" ratchet wheel H2lwithout, however, imparting any feeding movement tothe proof tapes. With the freeing of. the cam arm H0 from restraint by the star wheel H3, the spring I H imparts a rapid movement of the proofing hammer I 09 towardtheguide 99. This movement is sufliciently rapid to violently project or catapultthe plunger I09a toward the tape I03. so as to secure a staccato blow ensuring a good clean imprint upon the tape or strip I03 by the carbon upon the strip or tape I02.

The soft resilient head I096 of the proofing hammer will, as a result of printing impact with the types I00, cause a-rebound of ,the plunger 109a to within the cylinder I09c.-'

" -During the second clockwise movementof the crank handle 60, the locking member 43 will again be engaged with the teeth 42, the lost mo-- tion connectionibetween the sleeve H8 and the shaft 59 ensuring the locking of the setting wheel prior to the actuation of any of the other mechanisms receiving power from said crank handle 60. This second clockwisexmovement of the.

, crank handle 80 completes the cycle of operations when it is merely desired to setup a letter in a word, andthe various parts; except as to the disc 33,-actuated to set up a letter, have the same operative relation to each other as prior to the actuation of that disc.

If the first letter to be set up is in a paragraph, it is obvious that there'must be a plurality of complete cycles of operation of the crank handle 60 and the parts actuated thereby without turning of the setting wheel 39 or any of the discs 33. her of non-printing platens in the printing line corresponding with the quads or slugs used in hand setting type.

At this point it may be pointed out that the spring |2| will disengage the locking member 43 from the teeth 42 upon a contra-clockwise movement of the sleeve |8 by the spring 9.

The foregoing operations are repeated with each letter of a word, but are varied after the last letter of a word has been set, by the actuation of the machine to set the word spacing and line justifying mechanism.

When the last letter of a word has been set and before the second actuation of the crank handle 60 in the cycle of setting that letter, the end of the high part 31 of the setting bar 36 will be in engaging relation with the forward wall of the recess '16 in the pawl ring 1|. To set the pawls 11 and 1B, the shaft 32 is turned until the high part 31 of the setting bar engages the stop member 91 upon the disc 33. This is a short movement as indicated in dotted lines in Fig. 10.

During the movement of the shaft 32 and the setting bar '36 while the high part 31 of said bar is engaged with the wall of the recess 16, the pawl ring Tl will be moved in relation to the disc 33 carrying same. This movement isla combined rotary and radial movement, the movement of the cam 13 in relation to the spring 14 and the action of the cam 12 upon the clip Ill associated therewith, controlling the movements of the ring and respectivelypermit and impart a radial component of movement thereon. This radial movement brings the pawls l1 and 18 into engagement with filler bars 83 carried by the shaft 32, as shown in dotted lines in Fig. 10.

The short turning movement of the ring brings the shoes 8| closely adjacent the cam surfaces extending about the recess 69, these surfaces being formed upon the face of the discs proper 33. These shoes 8| being. of a thickness to be normally within the plane of the face of the discs 33, the setting of the pawls TI and I8 in the manner described will result in no movement of the discs longitudinally of the shaft 32.

When the pawl ring H has thus been actu-,

ated, the operator imparts the second clockwise movement of the crank handle 50, so as to move the setting bar out of engaging relation with the stop member 91 and with the pawl ring The engagement of the pawls and 18 with the filler bars 83 separates these pawls and tensions the spring 19. There is no ,fiexure of the. spring arms 82 during the setting of the pawl ring.

The setting of letters in succeeding words, the proofing of each letter as it is set and the actuation of the pawl rings upon the disc carrying the last letter of each word is repeated until a line has been completely set up.

In the machine herein described as actually constructed, there are six type carrying members 33 to the inch, and sixty such members are used in the machine, so a line approximately eleven inches long may be set up, the extra inch representing word spacing and line justifying tolerance.

In Figs. 15 and 16, the length of the length of This will result in the presence of a num-' the line is illustrated as being nine inches, in the actual machine and not in the drawings.

After a line has been set up, the operator draws the tapes I02 and |03 through the guide 99 and tears off a length of the tape ||l3, so that he can proof the line and count the number of letters.

and words in the line. In the line shown set up in said Figs. 15 and 16, there are forty-seven printing characters, including a period at the end of the line, and nine words, requiring eight spaces between words.

It will be noted, by reference to Fig. 15, that all of the discs 33 'are still in 'close abutting relation, one to the other, while in Fig. 16, the various words are'spaced apart a distance slightly less than the thickness of each disc 33. With this condition, the discs must be separated or.

would be required of the header 92 and the stop 94 must be adjusted accordingly. If the number of words were more, or the number of letters were more, lessmovement would be required of the header, -92 and the stop 94 would have to be set closer to said header. In some lines, where the number of words and letters is materially less than the space required in setting a nine inch line, it may be necessary, after the last letter of a word has been set, to actuate the crank handle 69 once without any movement of the shaft 32, to have a spacing quad positioned between succeeding words, and then to have thishandle actuated a second time to set the pawl ring '||v upon the disc having no printing character in the printing line.

When the stop 94 has been set, the shaft 88 is turned by its hand crank 90 so as to draw the head 84 nd the various filler bars 83 to the right, Fig. 4, to an extent to permit the springs 19 to move the pawls I1 and 18 into the keyways 35 exposed by the movement of these filler bars.

The shaft 32 is then turned, movement of this shaft being transmitted to the various pawl rings" which have been set in the manner heretofore described. With the turning of theserings, the spring arms 82 are moved circumferentially of the shaft 32, and the bearing shoes 8| move along the cams 80 and axially of said shaft, during which movement they engage the adjacent discs 33 to the right, sliding these discs along the shaft until further turning movement ofthe shaft and of the pawl rings is prevented by engagement of the stop rods 93 with the stop 94.

With this mode of operation the total amount of movement of the header 92, is divided substantially equally between the shoes upon each pawl ring which is actuated. For example, in the example illustrated in Figs. 15 and 16, the amount of movement of the header 92 is equal to the thickness of seven discs. Consequently, the spacing between the different words in the v set line will, in each instance, amount to seventwo letters are used, it would have been necessary to follow each word, during the setting of the line of types, with a disc having a nonprinting platen with its pawl ringset in the manner described, so that with the final actuation of these pa-wl rings, the spaces between the different words would be equal to the full width of a disc,

- plus one-half that width.

During this movement of the groups of discs, all of -the discs are limited to movement longitudinally of the shaft 32 by, the alining and locking bar 64, so that there willbe no disturbance of the types in the printing line.

Prior to the making of an impression upon the line of type so set, word spaced and Justified, a sheet of paper or stencil sheet is passed 'under one of the paper clips I32. The paper feed pawls 536 are then disengaged from the ratchet wheel E34 by movement of the slide I58 to engage the various stops I57 with the heels I56 of the various pawls. The paper roller or cylinder may then be turned freely by hand, the sheet being passed across the bar I26 forming the printing platen, and the bottom of the sheet engaged with the other clamp bar I3l.' The slide I58 is then returned to its normal inoperative position in relation to the feed pawls I38.

The operator then grasps the operating lever I49 by the handle I53 and rocks the shaft I48 in a clockwise direction from the right of Fig. 1. This movement of the shaft; I48 through the short arms I 5w rocksthe three armed lever l2I-'-I28-I5I about the shaft I29, thus, by a toggle lever action, forcing. the platen bar I26 toward the various type carrying members 33 so as to make an impression upon the paper passing over this platen. i

The movement of the shaft I23, when an inked impression is to be made will, through the mech- 'anism I55, bring the inking mechanism I54'into operative relation to the type uponthe printing line,'said inking mechanism having a direct and return reciprocation during the early stages in the movement of the three armed lever, andbeing actuated to ensure a proper application and distribution ofink during this reciprocation.v

I The detailed construction-and mode of oper: ation of thisinkingmechanism is'set forth in my co-pending application above referred to, and i need not be repeated' with the turning movement of the shaft I29. the arm I31 turns with the shaft and through the spring I38-rocks theiswing frame I33, the adjustable screw bearing upon the shaft I23 con-7..

said cam is moved to the leftin said figure.

As the impression platen bar I25 moves toward .the type carrying members'or discs 33, the auxiliary locking and alining bar IBI is encased by wheel 39; This mdvement of the shaft through e, the operating' 1 opposite direction by engagement with another gagement of this bar from the various discs 33 following the making of the impression.

'The upward arcuate path 'of the hooks I65. causes them to automatically clear the bar ISI following the initial return movement of said spring hooks.

After an impression has thus been made of a single lineof type, it is essential to re-distribute the types preparatoryto the setting of the next line.

Eollowing the making or the impression, the relation of parts will be as follows: The auxiliary locking and alining bar lfii will be disengaged from all of the discs 33. The high part 31! of the setting bar 36 will be disengaged from all oi the i discs used in setting up the line of type from which the impression was made. The lock bar high teeth I66 of the several discs will be spaced at upon the several discs appearing in the printing line. The stop bar it! will be moved out of the path of the various high teeth I65. The distributmg plate na will be set'in a position withthe heel 4 portion I and the toe portion H9 out of the plane of movement of said high teeth.

Before restoring the various discs 33 to their neutral position, the shaft 32 is given a contra" clockwise movement, see Fig. 13, Toy-the hand the pawl 18,-imparts a contra-elockwisemovemerit to the pawl rings II and moves the various bearing shoes 3| downwardly along the cam-surfaces 80. During this movement, the spring I4 .will exert a pressure tending to impart radial w movement to its pawl ring as it engages the cam -13 and as the cam I2 gomes into the operative relation with its associated clip". The spring I4, as the cam I3 passes thereunder, imparts the desired radial thrust to the ring to disengage the pawls "I1 and 18 from thekeyways 34', and completesthe turning movement of the pawl ring II to restore said-pawl ring to its normal position,
