16 Claims.

The invention relates to typewriters, printing machines and the like, and to the carriage moving and spacing mechanism on these devices. More particularly the present invention relates is to a mechanism as disclosed in my pending application, Serial Number 73,272 filed April 8, 1936, of which application this application forms a continuation-in-part.

An object of the invention is to provide in a device of the character described an automatic line 'justification means which will efiect'a slight and unnoticeable variation in the size of the letter spacing over a substantial portion of the line f whereby the decrease of spacings for causing a 5 vertical alignment of the right-hand end of the line will be distributed over said line or a substantial portion thereof not only between the words, as has been. heretofore provided, but also in the words themselves whereby, notwithstandmg the vertical alignment of the ends of the line and a variation in the letter spaces in the lines, no line will appear either crowded or expanded and no excessive spaces will appear between the words of the line as is common in ordinary justifled'printed matter.

' Another object of the invention is to provide an automatic line justification means of the char acter described which will provide for the automatic justification of type or printed matter throughout a'wide range of column widths and for causing a uniform spacing of the letters in each line regardless of the column width.

A further object of the invention is to provide an automatic line justification means which is adapted to justify several columns on a single part of the typed or printed page.

Still another object of the invention is to provide an automatic line justification means of the character above in which the several parts thereof will be specially designedto provide a maximum simplicity and positiveness of operation and be further adapted for use with present types of construction of typewriters and printing ma- 5 chines. i I

It is to be understood, however, that variations in the showing made by the said drawings and description may be adopted within the scope of the invention 55 as set forth in the claims.

The apparatus of the present invention, and as illustrated in the drawings, is arranged for use in combination with-a standard typewriter or 20 printing machine or any recording machine of this character having a base support or frame, a movable carriage and some means, such as an escapement mechanism operated through an assembly of type and keys, for releasing the car- 25 riage for'movement' in steps relative to the frame or support for spacing 'the letters and words of each recorded line. This type of mechanism is well known in the art and only parts thereof are here shown so as to simplify the disclosure and 30 better illustrate the operation of the line justification means of the present invention. For the purpose of the present disclosure there is illustrated part only of a carriage 1 and a carriage rack 8, the usual escapement mechanism for re- 5 leasing such rack for movement and a frame support of the mechanism as well as the keys and.

type and operating connections between the escapement and keys having been omitted in view of clarity and simplicity. As will be understood, in the usual typewriter or printing machine of this character the escape- Inent mechanism operates through a pinion to release the rack and carriage for movement by.

a tape 23 drawn by a spring mechanism, not

shown, so that the displacement of the carriage is exactly equal to the movement of the escapement mechanism. Thus for any given length'of recorded line the number of letter spaces isalways constant, and since usually the number of letter spaces must vary with each line, the lengths of the recorded lines are not uniform and an irregular right-hand margin results. With such a machine a justification of the lines may be effected only by a tedious and slow adjustment of the spaces between the words, which is not always satisfactory for the reason that the irregular spacing which is thereby required between the words is immediately apparent on viewing the recorded work. In accordance with the present invention, however, and as previously stated as an important object thereof, the size of the letter spaces for each line may be minutely adjusted so as to change the number of spaces in the line by one space so that a plurality of lines may be recorded, each differing from the other by a progres'sion of one letter space. Furthermore, this increase in the size of the letter space is distributed over the line,,or a substantial portion there- 15 of, so that the change of space between the letters and the words of the different lines will be entirely unnoticeable and the recorded work, as a whole, will have the appearance of perfect uniformitynotwithstanding the vertical alignment of the ends of the line and the variant number of spaces in the lines themselves.

This change in the size and number of letter spaces for a given length of line is effected by the interpositioning between the carriage rack and the carriage proper of a mechanism which will modify the movement permitted by the escapement mechanism to the carriage and which is displaceable to regulate the size of the steps of movement ,7 at the carriage. As will be seen from Figure 1 of the drawings, the rack 8 is mounted for movement relative to the carriage 1 by means of a sleeve 9 connected by brackets II and I2 to the ends of the rack 8 and which sleeve is reciprocally carried on a shaft I3 -ex- 5 tending longitudinally between the end plates I4 the shaft and I6 of the carriage. Preferably, due to the offset connection between therack and shaft}, a spring. I0 is connected between the bracket I and carriage plate I4 for holding the rack in engagement with the escapement, pinion (not shown). Means for transmitting the movement of the rack to the carriage proper consists of a crank I1 including an arm I8 'journalled by means of a shaft I9 to the carriage and including a lever member 2I which is in turn connected by a link 22 to the rack 8', the other end of the arm I8 being provided with a roller 20 which engages with an incline member 25 carried by the frame or support of the typewriter or printing machine. Thus as the carriage and-ra ck are released by the escapement mechanism and drawn widthwise of the arm by means of the tape 23, the arm I8 will be rotated by reason of the movement of the roller 28 over the incline member 25 and a relative displacement between the rack 8 and carriage 1 thereby effected according to the relative eccentric positioning of the link 22 and the member 2I to allow the carriage to move slightly further than the rack.

Viewed with greater detail it will be seen that I9 of the crank I1 i jou'rnalled in a bearing block 24 secured to the end wall I6 of the carriage, and the arm I8 of the crank extends for a considerable distance from the shaft I9 so that its rotational displacement may be minutely gauged, and also tg' minimize the vertical reacting force on the arm I8 tending to lift the carriage from the frame. of the typewriter. As will be further seen from lfigure 3, the lever member 2| is positioned on the shaft I9 at the forward end of the bearing block 24 and is provided with a lateral through the axis of the shaft I9. Formed in the face 26 are a plurality of notches 21 which are positioned on the face at uniform distances face 26 which passes from the axis of the shaft I 8 to the outer end of the face. The link 22- is pivoted to the bracket I'I adjacent the end I4 of the carriage and exprovided with a pin 3| for engagement in one of the several notches 21 in the face 26 of the eccentric member. To facilitate the selective engagement of the pin with the notches, the outer end 28 of the link is preferably formed as a handle for enabling the ready vertical manipulation of the link member. Also it will be noted that the spring I8 will function to resiliently retain the pin 3| in the desired notch of member 2|, this being particularly desired during the return movement of the carriage 1, since at such period the tension provided by the tape 23 is released. Preferably a graduated plate 32 is secured to the end wall I6 of the carriage and opposite the hand1e'28 for indicating the notch engaged by the pin 3|.

In the present arrangement of the lever 2 I, the lowermost notch 21 is positioned on the face 26 directly opposite the axis of the shaft I6 whereby with the pin 3| engaged in such notch there will be .no relative movement between the carriage and the rack regardless of the angular position of the arm I8. As will be understood, the movement of the pin 3| to the successive outer notches v21 on the face 26 will successively increase the amount of relative displacement be-.- tween the carriage and the rack for a given length of movement of the carriage assembly relative to the frame. In order that 51161308151011: ing of the pin 3 I in the successive outer notches will produce a substantially constant increment of displacement between the carriage and rack, three relatively important physical characteristics of thesmechanism'must be observed; First, the notches themselves should be equally and uniformly spaced on the face 26. Secondly the base of the notches should be positioned on a curved line having as the center of curvature for the longitudinal and angular displacement of the arm I8 relative to the incline member as the carriage moves'relative to the frame. In the accompanying drawings, the curve of the incline memberpresented to the roller 20 has been calculated j to give a substantially uniform rotation of the arm I8 for an average column length of fifty letter spaces as gauged on the standard typewriter. I have found that by the use of such a curve, the error present in column widths ranging from 25 to 75 letter spaces is entirely negligible.- In orderto produce a perfectly vertical right-hand margin, it is f her necessary that the modifying means be taken out of operation at a point where, for any member 25 the notch 21 adjacent the first notch 21 will produce exactly one less letter space in the line than with the pin'positioned in the notch 21', and. with the pin positioned in the second outer notch exactly two letter spaces less. and

given incline of the so on. In other words, for a given distance of separation of the notches 21 there will be an exact elevation on" the incline member 25 regardless' of the latter's angularity wherein the above relationship shall exist, or, stated in another way, there is one rotative position of the lever member 2| wherein the horizontal components of movement of the several notches will vary from each other by exactly oneletter space.

To take, the modifying means out of operation at this angular position of the lever member 2!, a'set-screw 35 is positioned on the end wall I6 ofthe carriage and may be adjusted to engage the lower end 31 of the lever member 2| to stop this member in its critical rotative position.

As an important feature of the present invention, I may vary over a relatively wide range the width of the recorded column within which the various positions of the pin 8| in the notches 21 will produce a complete letter space differential in the recorded line. This is eifected by changing the pitch or angularity of the incline member 25 so that the aforementioned rotational displacement of the arm- 18 to produce an exact vertical alignment of the right-hand margin of the column may be effected for various widthwise movements of the carriage relative to the frame. The means of adjusting the pitch of the incline member may be seen from Figures 2, 3 and 4 and as'there illustrated comprises a frame supported structure 38 to which an end 39 of the incline member 25 is pivoted. Mounted transversely from the structure 38 below and. to one side of the pivotal connection of the incline member is a tranverse pin 41 which supports the underside d2 of the incline member and is adjustable by means of a screw 53 to change the pitch or incline of the member 25. More specifically the supporting structure 38 comprises a pair of flat plates 44 and 45 which are connected at, their upper and lower ends with spacer bars 46 and 41 and are supported by the bar 46 on a frame supported bracket 48, the latter being secured to the frame of thetypewriter (not shown) and having an outer side 49 in the form of a flat strap or band which is enclosed, between the plates 44 and 45 and the spacer bars 46 and 41. The central portion of the lower spacer bar 41 is formed with a longitudinal open portion 51 in which is reciprocally mounted a slide member screw and longitudinal adjustment of the'pin 4|. In practice the screw 43 is set by moving the carriage to the extreme right margin'of the page to be recorded and then the screw 43 is adjusted so as to bring the arm l8 to its final rotated position, that is with the lower end 31.

of the arm engaged with the end of the screw 36. This operation may be facilitated by themounting of a graduated scale 10 on the plate 44 and an indicator member 1| on the slide 52. Thus by appropriate adjustment of the screw 43, and of the pitch of the incline member 25,

substantially any width of column may be recorded with the right-hand margin thereof perfectly justified.

As a further important feature of the present invention, I may adjust the widthwise position of the incline member25 relative to the frame whereby a justified recorded column may be variously positioned over a wide range on the 49, and within the enclosure defined by the plates 44 and 55 and the spacer bars 46 and 41, a plate 4! on the upper edge of which are provided a plurality of longitudinaily spaced notches 51. Pivotally mounted in a cut-away portion 58 at the end of the upper spacer bar s6, is a key 59 which is normally rocked by a spring 51 to engage a pawl 62 at the opposite end of the key in one of the notches 51 to thereby hold the supporting structure 38 against widthwise movement on the frame members 58 and 59. However, on depression of the end 63 of the key opposite the pawl 62 to withdraw the pawl from one of the notches, the assembly 38, together with the incline member 25, may be freely adjusted widthwise of the frame and held fixed in adjusted positions by re-engaging the pawl 62 with an appropriate notch 51; Desirably these notches are spaced by a uniform distance, say of one-half inch, whereby the left-hand margin of the column may be adjusted'on the recorded page as desired. In operation the carriage is set at the left-hand margin of the column to be recorded and the operator then adjusts the supporting structure 33 widthwise of the frame to position the pivotal connection of the upper end 39 of the incline member directly under the roller 2|). Preferably a horizontal plate 66 is mounted adjacent the incline member 25 for supporting the roller 28 when the latter is tothe left of the incline member 25 and during the widthwise adjustment of this member.

In operating the present apparatus, the subject matter to be recorded is preferably first typed on a standard typewriter or the like, or on the present apparatus with the pin 3| positioned in the lowermost notch 21' to prevent any modification of the size of the letter space.

Such a standard recorded column is illustrated in' Figure 5 of the drawings. The irregularity of the right-hand margin may be simply analyzed by drawing one or more vertical lines roller 20. The carriage is then moved to the arm l8 into a rotative position where the lower end 21 of the eccentric member is engaged by the set screw 36. The operator is then ready to start. Before starting to type the first line the operator notes that such line is three spaces short of the longest line in the recorded column, and accordingly he moves the handle 28 to engage the pin 3| with the third notch from the pivotal connection of the lever member 2| and then proceeds to type the line in the usual fashion. Since the second line is equally short the handle 28 is left in the same position for the typing of the second line, but prior to the typing of the third line the operator, noting that this line is seven spaces short, moves the handle to the seventh notch 21 from the pivotal connection of the eccentric member 2|. with a proper initial setting of the handle 28.

The result of the above recording made in the manner described with the present apparatus is illustrated in Figure 6, wherein it will be noted that each short line in the original recording has been lengthened to exactly thesame length as the longest line and a perfect vertical alignment of the right-hand margin of the recorded subject matter results. Figures 5 and 6 have been printed from plates made by a photoprinting process and are exact reproductions of the two sets of .typing, only reduced.
