Specification of Letters Patent.

Patented Oct. 8, 1918.

Application filed July 15, 1916. SerialNo. 109,466.

To all whom it may concern Be it known that I, BENJAMIN W. TUCKER,

a citizen of the United States, and a resident ofSouth Orange, county of Essex, and State of New- Jersey, have invented certain new and useful Improvements inType-Writing Machines, of which the following is a full, clear, and exact description.

This invention relates more particularly to platen carriages of front strike or other visible writing machines.

One of the principal objects of the invention is to provide a platen carriage which may be extended various distances, to adapt the same to hold work sheets of various lengths or widths, and much wider than the ordinary or normal length of the carriage, and which is so constructed that the lines of writing may be of the ordinary length or of an abnormal length, according to the width of the work sheet, and such'additional vide-simple and .eflicient means whereby the carriage may be extended different lengths,

and held in suchextended position; to provide simple means whereby an extended carriage or one of normal length may be made to travel alonga bed without extending said bed; to provide means whereby the carriage may have the various parts cooperating therewith, whether in a normal or in an extended condition, and withoutany disconnection or disarrangements of; the parts;

and to provide simple means whereby two sets of dog carriers mayv cooperate withthe single rack, either at the same time or at different times, to adapt a long or ashort carriage to travel along a relatively short bed.

to provide simple and efficient means whereby the carrlage may be positively held in any of its adjusted positions; and to provide a construction whereby'the carriage base or parts may be telescoped or extended at will.

A further object of the invention is to provide a carriage which is adapted for use either on small portable visible typewriters, or adapted for use in connection with writing machines of various kinds and constructions.

With these and other objects in view, the invention will be hereinafter more particularly described with reference to the accompanying drawings, which form a part of this application, andwill then bepointed out in the claims at the end of the description.

The bed 10 may be supported in any suitable way. and adapted to travel along said bed or other support is a carriage which has end plates or brackets 12 and 13, and said end plates or brackets are connected together by an extensible and telescopic base 14. This base 14 comprises an outer part or member 15, and two slidable members 16 and 16*, one of which is secured to the end bracket 12, and the other to the carriage end bracket 13, and both of which members 16 and 16 are held to slide within the outer member 15. 'The outer member 15 is of a box-like form, and comprises a top portion 17, and a bottom portion 18, rigidly held together, and serves to inclose the inner, members 16 and 16 when in the normal and nonextended condition of the carriage. The slidable and telescopic members 16 and 16 are similarly constructedand are substantially U-shaped in cross section, and are adapted at the sides and top portion thereof to bear against and slide along the walls of the base member 15. The outer member 15 of the base is provided with L-shaped brackets 19, the lower portion of which is adapted to engage'track surfaces 20 along thefront and rear edges of the bed 10, and adapted to travel along said track surfaces are rolls 21 held to the ends of shafts or rods 22 and by which the carriage is adapted to beheld to travel lengthwise of the bed, there being any desired number of these rolls 21 to support the carriage properly in its letter space travel.

A bracket 23 'is arranged substantially midway of the outer base member 15, and is secured. to the upper portion thereof by screws 24 or otherwise. Thebracket 23 has a pendant portion 25, which is provided with a threaded aperture. A two part screw 26 has one part 27 exteriorly threaded, and is adapted to engage the threaded aperture in the part 25 of the bracket 23. This part 27 is tubular in form, and is provided with an internal thread, which is adapted to be engaged by the threaded end of the screw part 28. The screw part 28 is held to the carriage end bracket 12, and the screw part 27 is rotatably held against lengthwise relative movement in the carriage'end bracket 13, but in such a way as to be rotatable therein. The screw part 28'has its outer end reduced, and is held against rotary movement in the end bracket 12 by means of a screw 29 and washer 30, or otherwise, and the screw part 27'is held to rotate with the rod 31 which extends through the carriage bracket 13, and has on the outer end thereof a knob 32 provided with a knurled head, by means of which the screw part 27 may be rotated The screw part 27 has a right hand thread and the screw part 28- a left hand thread, and the pitch of the threads of the to permit the two part screw to engage the part 25 of the bracket 23, without interfermg with said bracket.

t will be evident, that byreason of the two part screw and its engagement with the part 25 of the bracket, and by reason of the base part 16and 16 being held to the end brackets 12 and 13 respectively, thatb rotating the screw part 27 by means of the knob 32 the two part screw will have the parts thereof forced apart when the knob 32 1s rotated in one directionfthus extending the carriage end plates 12 and 13 and movmg therewith the carriage base parts 16 and 16*, while a reverse movement-of the knob 32 will cause the two carriage end plates and the base parts to be collapsed and moved toward each other to the position shown in Figs. 1 and 12. a

The platen 33 is mounted to rotate in the carnage, and is adapted to move with the carriage in its normal condition, or to move with the carriage, or held stationary during the movement of the carriage when the latter is in an abnormal or'extended condition.

1 This platen comprises a tubular body 34,

which may be made similar to the ordinary platen, or in any preferred way, and is mounted to rotate with an axis or shaft 35. The axis or shaft is extensible and is formed in two parts 36 and 37, so as to slide rela- 10 tively with respect to each other. One of the members, as 3.6, is rotatably held at its outer end in the carriage end piece 12, and the platen axis member 37 is rotatably held in the carriag end piece or bracket 13. The two members 36 and 37 are semi-cylindrical at one portion thereof, and have straight portions, as 38, which slide upon each other, and by reason of such portions the two members 36 and 37 of the platen shaft or axis will always rotate in unison. The platen body 34 is slidingly held to the shaft or axis member 37 by making the part 37 square or otherwise, so that a relative lengthwise movement may take place between the body 34 and the axis members 36 and 37, and still the axis members and platen body 34 be made to rotate together. At the outer end of the axis or shaft member 37 is a pinion 40, having a sleeve portion through which the platen shaft member 37 passes. The shaft members 36 and 37 may be connected together by a telescopic bar or member 41. This bar or member comprises two parts, 42 and 43, and each have an overlapping substantially U-shaped part 44, which permits one part of said bar to slide relatively to the other to partake of the extended or collapsed condition of the carriage end plates or brackets' 12 and 13 of the carriage base, said parts 42 and 43 bein adapted to pass through openings in sai end plates 12 and 13 respectively. 'The members 42 and 43 of the bar 41 have parts 45 and 45*" respectively, one of which is held to the outer end of the platen axis shaft 36 and the other to the platen axis shaft part 37. The part 45 of the bar 41 has a downwardly projectingportion or stop 46, and the part 45 a proj ecting portion or stop 46 and these stops 46 and 46 are'adapted to engage parts on the carriage bed 10, when it is desired to write. lines longer than the usual travel 'of the carriage. In this ase the parts 46 and 46 do not directly engage the carriage bed, but each engage an upwardly projecting finger 47 on a slide 48, located at each end of the carriage bed 10. This slide is shown best in Figs. 5 and 21 to 24 inclusive, and is adapted to be positioned to cause the parts 46 and 46 to engage the fingers 47 or to prevent such engagement for a purpose to be presently described. The slides 48 are in the form of a plate, having slots in the body, through which pass screws 49, and are each provided with a finger piece 50 by which each slide 48 may be moved at the will of the operator.

The slides 48 are moved so as not to engage the projecting parts 46 and 46* when the carriage is in its normal non-extended condition, but when extended, as shown in Figs.

.21 to 24, the slides are positioned so that the upwardly projectin portions 47 are in position to be engaged 46 The carriage end pieces 12 and 13 are extended by means of the two part screw on the rotation of the knob 32, as already described, and the carriage has its letter space movement controlled by suitable escapement, one form of which will be pres ently described. When the carriage is moved to the right to begin a line of printing the part 46 at the left of the carriage will engage the part 47 on that side of the bed 10, as shown in Fig. 21, which permits the carriage to move to the position shown in Fig. 21, the bar members 42 and 43 being held at this time to permit relative movement of the carriage end pieces or brackets 12 and 13. During the letter space movement of the carriage the writing may be continued throughout the entire length of the platen, all parts moving together and when near the end of the platen the stop 46 on the right hand side will engage the projection 47 on that side of the carriage bed, and will hold the platen against movement. The subsequent printing will be at the same printing point on the platen, and during the letter spacing movement of the carriage the carriage with the end plates will be moved from the position shown in Figs. 21 and 23 to that shown in Fig. 24. Thus the printing of a line much wider than the carriage bed and the normal size of the carriage takes place automatically, Without using interchangeable platens. or a sectional platen, and without the necessity for shifting the paper.

The work sheet during the printing operation is not held directly about the platen and to the same, as is usually the case, but said work sheet is held above and below the platen so as to rest simply against the face of the platen along the printing line, as it is necessary under the construction shown, that the work sheet, when the carriage is extended and long lines wider than the usual size of the carriage are. to be printed and during the time that the platen is held stationary, travels with the carriage is held between the paper finger rolls 53,

and the larger rolls 54, and intermediate the rolls 1s a pressure finger 54 -for forcing the work sheet at the prmting point against the platen, said pressure finger being held to a type aliner 54 or otherwise. The rolls y the said parts 46 and 53 are held to paper fingers 55, which are adjustable along the bar 55, or otherwlse, as preferred, said paper fingers having a substantially U-shaped part 56 to fit over said bar 55 to hold the same frictionally tional supporting bar or support 59. This support or bar comprises a plurality of sections which may be rectangular in form so that they will not rotate relatively. The sections of the supporting bar 59 correspond in number to the number of sections of the-rolls 52 and 54, and each section of the bar or support 59 has projecting outwardly from each end thereof one of a pair of arms 58,so that said arms will be arranged in pairs and each pair being 7 adapted to supportits individual pressure roll section, there being a bushing or collar at the end of each roll section which is held to one of the arms 58 and assists in guiding the rods 57. A lazy tong movement 60 is provided to maintain the sections of the rolls 52 and 54, and the sections of the bar or support 59 in their proper relative positions, and to cause said rolls to be moved toward and from each other during the extension or collapsing of the carriage. The lazy tong 60 has the usual links operatively connected together, and one end of the lazy ton is connected at 61 to a collar or a projection on the carriage end plate 13, and the opposite end is similarly connected to the carriage end plate 12. The lazy tong links are held at 62, Figs. 8 and 9, to one of the outer bar sections, and at 63 to the intermediate bar section. In Figs. 8 and 9 only one end of the carriage is shown, but the opposite end thereof is similarly constructed and the two parts of the lazy tong are connected by long horizontally arranged links 64. This arrangement will cause the sections of the support 59 and the pressure rolls 52 and 54 to be spread apart, the intermediate section of the support 59 and the intermediate pressure rolls remaining normally centrally of the carriage in both its normal collapsed condition and in its abnorma'l extended condition. The construction of the sectional bar or support 59 is best shown in Figs. 6, 7, 10, 16 and 17. Each section comprises a square tubular part 65, to the center one of which is secureda square tube 66 which projects from opposite sides'of the central part so as to enterthe adjacent sections and form a guide therefor. At each end of'the carriage is a normally stationary square bar 67, the inner end of which slides within the opening of its adjacent section and also projects onto the center section. The pressure rolls 51 co operate with the sections of the lower rolls 52, and said rolls 51 'are'mounted torotate upon the forward portion of the paper apron 68. This paper apron is of a plate like form common to carriages of different kinds of writing machines, and is normally forced in one direction by one or more springs 69 to cause the work sheet to be gripped between the rolls 51 and the sections of the roll 52, so that when said rolls are rotated, as will be presently described, the work sheet will be moved past the platen for the different lines of printing. As shown, there are two rolls 51, each separately journaled in the paper apron and said rolls are each of such a length as to cooperate with two of the lower pressure roll sections, whether the carriage is in the normal condition or in an extended condition.

The pressure rolls 51 may be released in any suitable way. Asshown, a finger 70 is pivotally held to the upper portion of the bracket 23, and adapted to engage said finger 70 is a square rod 71. The rod 71 has a sliding connection with the finger 70, and is of such a length as will permit the extension of the carriage without disengagement of the rod from said finger. At the outer end of the rod 71 is a finger lever 72, by which the rod 71 may be rocked, thus causing the finger 70 to engage the paper apron and'move the same against the tension of the spring 69, and thereby force the roll 51 away from the pressure roll 52, thus freeing the work sheet to permit the same to be adjusted or for other reasons, as usual in machines of this kind.

As a means for controlling the letter feed movement of the carriage along the bed 10 I provide two dog carriers 73 and 74, which are adapted to cotiperate together or individually with a rack 75 mounted upon the carriage base. The dog carriers 73 and 74 are similarly constructed. Each of the dog carriers is pivoted at 76 at one end, and may be guided at its other end in a bracket 77. On each arm or carrier are arranged two dogs, one of which may be a fixed dog and the other a loose dog, and both of which are adapted to coiiperate with the rack to permit the carriage to move a letter space each time the escapement is tripped, as is usual, it beingunderstood that any suitable escapement means may be employed. Each dog carrier is normally forced in one direction by a spring 7 8, and in the opposite direction by a tappet 7 9. There are twotappets 79, one for each escapement carrier, and said tappets are adapted to engage projections 80 on side carriers. The tappets 79 form extensions of a rocking bar 81 which is operativelyconnected to the universal bar. As shown, the rocking bar forms a part of the universal bar frame, and may be operated in substantially the same way as in the Corona typewriter, and during each rocking movement is adapted to trip the escapements, the carriage being under the tension of a spring in a drum 82, from which extends a cord or other flexible connection. 83, as is usual in the Corona typewriter and other writing machines.

The rocking frame 81 may be made to vibrate the ribbon to and from the printing point, or permit the same to remain inactive and the carriage and parts cooperating therewith may be mounted upon a foldable support, as in the Corona typewriter. but the invention is not limited to such features nor to the particular type of machine with which the invention may be used.

The platen may be rotated and line spaced in any desired manner. As one means, a gear 81 is mounted to rotate on the outer end of one of the rods of the sectional support 59. The gear is provided with a knob 85 to rotate the same, and said gear is adapted to mesh with the pinion 4-0 on the platen shaft or axis, a pinion 86 on the shaft of the pressure rolls 52, and a pinion 86 on the shaft of the sectional pressure roll 54, so that the said shafts will rotate in unison, thus assisting in the feed of the work sheet manually in either direction, at the will of the operator. 4

A line spacing means is mounted at the end of the carriage opposite the knob 85. A large gear 87 similar to the gear 84 is mounted to rotate axially on the supporting bar 59, and held to move with the gear is a ratchet wheel 88.. The teeth of the ratchet wheel 88 are adapted-to be engaged by a pawl 89, and said pawl 89 is pivoted to a lever 90, and is normally forced into engagement with the teeth of the ratchet wheel 88, by means of a spring 91. The lever 90 is pivotally held to move independentlv of the ratchet wheel, and the gear 87, and may be made to move said gear various distances, such distances corresponding to one, two, orthree line s aces, or otherwise, by means of an adjustab 'e stop 91? shown in dotted lines in Fig. 2 and operated by a knob 91", or in any other desired way. The gear 87 meshes with the gear or pinion 92 on the shaft of the sectional 'roll 54, and said gear 87 also meshes with the gear 93 on the shaft of the sectional roll 52, thus rotating both rolls in unison, and forcing the work sheet about the platen for line spacing in the usual way.

The invention will be readily understood from the foregoing description, when taken in connection with the accompanying drawings. If the carriage is in the condition shown in Fig. 1, which is the normal position of the parts when writing upon work sheets of the usual width, the carriage in this case may be moved for letter spacing along the bed 10 in the usual way, If, on the other hand, it is desired to print or write lines on work sheets much wider or wider than the usual width of work sheets, the carriage in such case is extended by rotating the knob 32, so as to force the carriage end plates 12 and 13, and the parts mounted thereon and connected thereto in the manner already described, and to a distance corresponding to the width of the work sheet to be used with the carriage when thus extended. As thus extended the work sheet may be line spaced and adjusted as already explained, and the carriage will travel along the bed controlled by its feed mechanism. \Vhen the carriage is forced to the right, looking from the'front of the machine, the platen shaft part 36 is held against such movement by the engagement of the part 46 at the left of the machine with the projection 47.0n the carriage bed 10, thus permitting the carriage end plate 12 to move away from the part 45 a distance corresponding to the extension of the carriage. During the letter printing movement the carriage with the platen will move together for substantially the entire length of the platten, if the lines are to be written of a length greater than the length of the platen, until the projection or part 46 at the right of the machine engages the part 17'on the same side of the machine when the platen will be held against further movement. The carriage with the Work sheet may continue to move, at which time the carriage end plates willslide upon the parts 36 and 37 of the platen shaft or axis from the position shown in Fig. 23 to the position shown in Fig. 24, during which time the printing will be upon the same part of the platen for the reason that the platen during this additional writing or extension of line printing is held stationary.

It will be evident from the foregoing that the carriage may write lines on a work sheet of different lengths, and when the carriage is extended the writing may be continued entirely automatic, without any attention being paid whatever to the work sheet further than that required when writing the ordinary normal and usual length of lines.

In the drawings, different parts usually cooperating with the carriage are shown, such as margin stops, scale, type aliner, and other features, but such parts are shown for the purpose of illustrating how these parts may be arranged and mounted to adapt them to the form of platen carriage shown and de-' scribed herein, but such features, as well as many of the other parts, mav be of any suitable construction, and arranged in any desired way.
