TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 715,943, dated December 16, 1902.

Application filed October 28,1897. Serial No. 656,720. (No morleLi To @ZZ who-m, t may concern: 4

l Be it known that I, WALTER J. BARRON, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State 5 of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates, primarily, to the Io mounting of the platen-scale, and, secondarily, to a locking device for holding the platencarriage from shifting when turned up.

The main Object of the first part of my invention is to provide a construction by which I5 the platen-scale of an under-strike machine may move automatically to the line of print as the platen is raised and swung rearwardly and may also move automatically from the line of print as the platen is moved forwardly 2o and lowered for the renewal of the writing.

So far as this part of the invention is concerned, however, it is not essential that the platen be swung downwardly to receive the type-impressions, and hence the general improvements are applicable as well to front strike and other visible-writing machines. yThe improvements embrace novel features of invention which may beused whether or not the scale moves automatically and whether 3o or not the independent movement of the scale is eiected by manipulation of the platenframe. In any' case the desired movements of the scale take place while the last line of writing or the printing-line is in full view of the operator and accessible for purposes of alinement of the paper or erasure of errors.

My improvements consist in the various features of construction and combinations of devices hereinafter more fully described, 4o and particularly pointed out in the appended claims.

' In the accompanying drawings, Figure lis a front elevation of a portion of a type-writing machine embodying my improvements and showing the platen-carrier tu rned up and back beyond an upright position for inspection and correction ,of the work. Fig. 2 is a View of the carriage, &c., from beneath and when 'the'platen-f'r'ame is down in working This view also indicates the rela- "tion of the platen-scale. when the platen-frame is swung up to about a vertical position, but before it is moved so far rearwardly as is indicated at Figs. l and 3. Fig. A3 is a side elevation of the machine, showing the platen-carriage in the condition represented at Fig. l. Fig. Lis a similar view, but showing the platen-frame swung upwardly to exhibit the line of writing. Fig. 5 is an enlarged side elevation, partlyin section, showing more particularly the platen-frame-locking device. Fig. 6 is a similar view thereof, but showing the platen-frame at the limit of its upward and rearward swinging movement and the locking device as in action; and Fig. 7 is a plan View of the same as shown at Fig. 5.

In the various views the same parts will be found designated by the same numerals of reference.

I have shown my improvements carried out in that type of machine known as the Remington No. 6; but it will be understood, of

course, that they may be embodied in the Densmore and other styles or makes of machines.

l designates the main carriage or truck, and 2 the guide-rail upon which .the truckrollers 3 travel. This main carriage or truck, as heretofore, is so held down upon its guiderail as that it has only a rectilinear movement.

4 represents the platen carriage or frame, which is pivotally connected to the main carriage l, so that it may not only travel longitudinally with said carriage, but it may also be turned up and down independently of said carriage for inspection and correction of the work. For this purpose, as heretofore, a rock-A shaft 5 is mounted at its ends in the ends of the main carriage, and at near each end of said rock-shaft is a rocker-arm 6, which projects upwardly. To thev free ends of said rocker-arms is pivotally connected the rear side of the platen carrier or frame. The rear end of each side or end bar 7 is forked or'bifurcated, as at 8, to embrace one of said rocker-arms, and through perforations in the branches of said fork and said rocker-arm is passed a pivot-pin 9, which is preferably prolonged, s o as to extend out between two screwstops 10 10, set horizontally in lugs at the end IOO of the main carriage. Thus the platen-carrier is hinged or pivoted or pivotally connected to the main carriage, so that it is capable of being freely swung up and down independently of said carriage. The back bar 11 of the platen-carrier may be made integral with the side bars 7 thereof, as may also the front carriage-bar 12, which may bear centrally of its length a wheel or roller 13 to travel over the usual shift-rail. (Not shown.)

14 designates a cylindrical platen or roller the shaft or axle of which is mounted in suitable bearings in the side bars of the platencarrier, and on the under side of said platen when it is turned down in working position is arranged a scale-bar 15, marked and graduated in the usual manner, but mounted and operated in a novel way. At each end of the platen-scale is attached an arm 16, which is slotted at 17 and supported and guided by a screw 18, projecting from a rod 19, which extends longitudinally of the platen-frame and is supported at its ends by screws in the side bars thereof. At near each end or" the scalebar is also attached one end of a coil-spring 20, the opposite end of which is attached to the said rod 19. Said springs tend normally to draw the scale toward said rod or circumferentially of the platen, and the scale is forced away from said rod substantially circumferentially of the platen or in the opposite direction by means of cams or curved projections 21, which act upon the free ends of the slotted arms 16. These cams or curved projections are preferably formed integral with the devices which operate to lock the platen when in its upturned position. Each said device consists of a horizontal plate-like portion 22, a lug 23, which is pivoted upon the platen-carrier hinge-pin 9, a vertical plate-like portion 24, which acts as a stop to the turning-up and swingingback movements of the platen-carrier, as sllown at Fig. 6, and the cam or curved projection 21, and which, like the part 24, is also arranged in a vertical plane. The plate 22 is slotted at 25 to enable it to shift back and forth transversely of the main carriage and is guided thereat by means ofa screw 26, projecting upwardly from said carriage. The said plate is also provided with two holes or depressions 27 28, arranged in the same line transversely of the carriage and adapted each to a fixed pin 29, projecting upwardly from the main carriage. Ou the said cross-rod 19 is supported, by means of suitable clips or brackets 30, the slightlycurved paper guide or deector 31, which is a plate-like device extending substantially the length of the platen and formed with openings 32 for the accommodation of the several sections of the feed-roller 33, which presses against the platen or the paper thereon. The feed-roller shaft 34 is mounted at its ends in spring-pressed hangers or brackets 35, mounted on the back bar 11 of the platen-carrier, al1 in the usual way. The paper in feeding toward the printing-point passes between the scale 15 and the platen; The platen-scale should be arranged as close as possible to the printing point or line. Generally in a single-type machine the edge of the scale is set back of the printing-point a slight distance in excess of the height of a type-space, and in a double-type machinethat is, two types on a bar-the scale is set back a distance slightly in excessA of that between the outside extremities of the two types. This makes it difficult or inconvenient to make corrections. When a sheet is inserted for correction, the printed line is drawn down to the line of the scale edge for truing the paper, and then the platen is rotated a distance of one or two line-spaces, according as the machine is of the single-type or of the double-type description, to bring the line of print into register with the impressionpoint when the platen is turned down in working position. One object of this invention is to avoid this trouble and operation, and to that end the scale, which in the present machine must stand back two type-spaces from the impression-plane, is so mounted that when the platen is turned up and back the scale is automatically shifted circumferentially or widthwise, so that its edge registers substantially with the impression-point, and hence the operator has only to shift or move the paper to bring the line to be corrected or the date or other line to be printed on into register with the edge of the scale. Then after observing the point at which the correction is to be made or the plane at which the printing is to be done the platen is turned forwardly and down and the carriage is moved so that the front scale 36 registers with the frame pointer or index at the desired point. When the platen is turned down, the line to be corrected comes into register with the printing-plane, and duringl the turning down of the platen the scale automatically returns to an out-of-the-way position two type-spaces olf from the line to be corrected. It will be seen that this saves the trouble heretofore experienced with the relatively-fixed or irnmovable scale of first registering the line to be corrected with the scale and then after such registering feeding the paper away from the scale to the proper extent, so that the line will register with the printing-point. In other words, with this contrivauce the scale is automatically moved to that part of the platen which when in working position lies in or is brought to the printing-plane, and the paper may be adjusted at once to the proper position and without any subsequent adjustment of the platen and paper to bring the line to be corrected into the impression plane.

It will be understood from the drawings that when the platen is turned up the ends of the arms 16 are brought into contact with and ride against the cams 21 and are by said cams forced or moved endwise, thus moving the scale circumferentially of the platen against IOO IIO

the tension of the springs 20, and thus bringing the edge of the scale forward to register with that portion of the platen which when turned down into working position again will register with the impression-point. The edge of the scale having been in this manner shifted or moved to the impression-point the paper may be now manipulated so as to bring the line of print which is to be operated upon directly into alinement with the edge of ther scale, and when this operation has been performed the platen may be turned down toits working position without independent rotative manipulation, as heretofore, and when brought down to such position said line of print will register at once with the impression plane, and the work of type-writing may be resumed instantly. In said turning-down movement of the platen to Working position the scale is automatically moved away from the adjusted line of print, so as to be ont of the way of the types, by reason of the fact that the ends of the arms 16 move out of operative relation with the said cams and leave the springs 20 free to act upon the scale and return it to its first position. The forward free edge of the guide or deector 3l termi-l nates back of the printing-pointfar enough to be out of the way of the types, and normally, or when the platen is down in Working position, the edge of the scale substantially coincides with the said free edge of the deector; but when the platen is turned up and the scale automatically advances to the irnpression-point it consequently moves away from the fixed deiiector, and a two-type space, more or less, is created between the edge of the scale and the edge of the detlector. By reason of the space or opening thus formed it has been found in practice that if the paper be inserted while the platen is in its upturned position there is a liability of the paper passing into said space or in between the deliector and the scale and stopping and becoming wrinkled and creased. To avoid this diculty, I have provided the scale with a depending ledge or apron 37, which is of such a width as always to overlap the said deflector, and thus close the gap or space between said deiiector and said scale andact as a guide to properly direct the leading edge of the inserted paper forward under the edge of the scale. While I have shown this ledge or apron 37 as extending for nearly the full length of the scale, I have also found in practice vthat the end portions onlyof said ledge or apron are needed to perform this service,

'excepting for Very narrow sheets, and thereplaten to keep it away from the paper the proper distance by means of ad justing-screws 38, set in threaded holes in the arms 16, so that the points of said screws may bear on or against the surface of the deector. By turning said screws in or out the edge of the scale may be adjusted to the desired distance from the surface of the platen. As the springs operate to start the retraction of the scale immediately the turning-down movement of the platencarrier is commenced, the said scale may in consequence be used as a ruler for under'scoring purposes, it being only necessary to swing the platen-carrier forward slightly to cause the scale to recede a short distance below the line of print, and when the proper distance has been reached a pen, pencil, or the like may be run along in contact with the edge of the scale to produce the desired underscoring.

The lower portions of the working faces of the cams2l are so shaped as to permit a prompt retraction of the scale l5 from the printingline by the springs 20, or, in other words, a slight forward swinging movement of the platen-frame will cause a movement of the scale from the position indicated at Fig. l to thatindicated at Fig. 2, so that while the line being written or the printing-line is still in front of the platen, and hence in view of the operator and accessible for underscoring or erasures, the scale is moved downwardly away from said printing-line, either a slight distance to permit the use of the scale as a ruler for marking underscore-lines upon the paper, or a greater distance, so that erasures may be freely made without contact of the erasing rubber or knife with the scale, which is an advantage of considerable importance. When the platen is swung up and back to the limit, as at Figs. l and 3, theA paper is inserted and the line or portion to be printed on is brought into register with the scale, and then the platen is lowered and the writing begun, the ty pe-im pressions falling upon the line with which the scale registered at Fig. l. When making corrections, the paper is insertedand adjusted in the same way, and then the platen-frame is swung forwardly a little until the scale is retracted or moved downwardly away from the printing-line to substantially the position shown at Fig. 2, so that while the platen-carrier is Ain this intermediate position and the writing is in full view and the printing-line is accessible ,the scale is far enough away from'the printingline to permit erasures to be made ,convenswung rearwardly again to permit compari'- IOO IIO

son of the printing-line with the scale to make sure that the paper has not been moved by the erasing-rubber, and then the platen may be swung downwardly and the type-keys operated. Inasmuch as a slight forward motion of the platen-frame is sucient to move the scale to the relative position indicated at Fig. 2, it is apparent that no further retraction of the scale occurs or needs to occur during the completion of the forward and downward movement of the platen, since said scale is already far enough away from the printingline to clear the path of the types. On the other hand, the greater part of the turningnp movement of the platen occurs with little if any independent movement of the scale 15; but in the last portion of the platen movement or when said platen is moving rearwardly practically in a horizontal line the ends of the arms 16 may be operated upon by the relatively Xed cams and the scale quickly moved into register with the printing-line. Viewed in one way, therefore, the movementof the platen-frame may be divided into two portions, one portion consisting in a movement upwardly from working position to exhibit the line of writing and the other portion consisting in a subsequent rearward movement to effect a movement of the scale into register with the line of writing. It will be observed that the scale remains close to the platen during its independent movements, but preferably not in contact With the platen. The scale may be held pressed toward the platen by means of the usual spring-guides 39 or by other suitable means.

I have shown in the drawings various devices usually employed on 'or in connection with the Remington No. 6 machine, but which need not be described, since they do not form a part of my improvements.

Referring now to the platen-frame-locking devices, which carry the cams for actuating the scale in one direction, it will be seen by an inspection of Fig. 6 that when the platencarrieris up in non-working position and with its stop-pin 9 against the back stop-screw 10 the platen-carrier cannot be shifted forward, so that said pin will strike the front stop-screw 10 by reason of the fact that the screw-pin 29 occupies the hole or recess 28 in the bottom plate 22 of the said locking device; but when the platen-carrier is turned down to a horizontal working condition the forked part S of the end bar strikes against a forwardly-projecting lug 40 on said locking device, as shown at Fig. 5, and causes the same to vibrate about its pivot, lifting the rear perforated end sufficiently to disengage it from the locking-pin 29, and while the parts are in this condition the platen may be shifted freely for upper and lower case printing. In the position of the platen-carrier rocker-arms 6 at Figs. 5 and 6 the platencarrier is held normally in upper-case printing position by means of the usual shiftingspring mechanism, not shown 5) but when the said mechanism is actuated to bring the platen-carrier normally into lower-case printing position the said rocker-arms are vibrated and the pivot-pin 9 is caused to press normally against the front stop-screw 10, and in this shifting movement the locking devices are of course carried forward with the platencarrier, and the holes or recesses 27 therein are brought into operative relation with the locking-pins 29, fixed in the main non-shifting carriage, so that when the platen-carrier is turned up from its normal lower-case printing position the holes or recesses 27 engage the upper ends of the locking-pins and prevent the platen-carrier from accidentally shifting rearwardly at such time, and of course when the platen-carrier is turned down again to its Working position the said end bars 8 again strike upon the projections 40 and lift the locking devices out of engagement with said pins, thus leaving the carriage free to be shifted back and forth as before, the slots 25 in the locking-plates permitting them to shift back and forth with the platen-carrier. One or the other of the holes 27 28 is always in line with the locking-pin 29 in either of the two shifting positions of the platen-carrier, and hence the instant the platen-carrier is lifted to be turned up and its weight is removed from the projection 40 the locking device drops by gravity and is engaged by the said pin 29, thus eifectually holding the platencarrier from any shifting movement during the entire turning up and down of said carriage. The cams 21 being fixed to the pivyoted and sliding locking devices have therefore a fixed relation to the ends of the scalesupporting arms 16 in either of the shifted positions of the platen-carrier, so that the said arms and cams may work together to move the scale toward the printing-point in both the lower-case and upper-case positions of the platen-carrier.

Various changes in detail construction and arrangement may of course be made without departing from the gist of my several improvements, especially where the invention is adapted to other styles or makes of machines.
