T (ZZZ whom it may concern:

Be it known that I, Gnomes W. Dornvrno, a citizen of the United States, residing at Stamford, in the county of Fairlield and State of Connecticut, have invented certain new and useful Improvements in Tabulating Devices for Type-v riters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the present invention is to provide means, in connection with a typewriter or other writing-machine, for facilitating the positioning and stopping of the traveling-carriage thereof at predetermined points, as for tabulating, or other like work.

Furthermore, the object is to present a typewriter embodying means for effecting easy, absolutely certain, and arbitrary positioning of the traveling carriage at any predetermined point in its travel by initiallyselecting the point to which said carriage is to be moved and, thereupon, moving said carriage to said point.

i urthermore, the object is to present a tabulating device for use, particularly, in flat-platen typewriters, by which the operator shall, at all times, retain full and absolute control of the carriage, whereby the usual shock and jar occasioned by the sudden arresting of the carriage, at a tabulatorstop or abutment, is obviated.

hurthermore, the object is to produce a tabulating device for typewriters capable of accurately positioning the device in an easy and expeditious manner, with necessity of operating only a minimum number of parts to effect the result.

Furthermore, the object is to present means whereby the carriage is arrested, in its travel in one direction, at predetermined points, without or shock to the machine, and be capable of la ching by said means without displacement or rearranging the parts thereof during its return to its initial or starting point, that is,in a direction opposite to that of writing.

Furthermore, the object is to present indieating means for shoning the position on a selecting member of the relative printing point.

The invention has other objects which w ill more fully appear iereinafter.

w ith these objects in view, the invention Specification of Letters Patent.

resides in the novel construction, arrangement, and combination of parts more fully hereafter described and claimed.

in the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts, I have illustrated one of many embodiments of my invention, it being understood that the same is capable of great variation without departing from the spirit thereof.

In these drawings: Figure 1 is a view in perspective of the transversely-traveling carriage of a fiat-platen typewriter, carrying, on its top-plate, letter-spacing mechanism and l my improved tabulator device, some parts of {the machine being broken away to show others more clearly Fig. 2 is a view in plan thereof; Fig. 3 is a view in front elevation thereof; Fig. 4 is a view in side elevation thereof, showing, in dotted lines, the parts of the device when operated; Figs. 5 and 6 are views in detail, showing the latching-device, disposed on the tabulating operator-lever, in its various operative positions with relation to a tabulator-stop; Fig. 7 is a detached bottom plan View of the tabulating-selectinglever; Fig. 7 is a fragmentary View of a modified form of the indicating instrumentalities of the structure; Fig. 8 is a view of a modified form thereof Figs. 9 and 10 are views respectively in front and side elevation of a form of tabulator-stop Fig. 11 is a View in side elevation, showing the tabulator operating-lever without a latching-device, the stop being provided with such device; Figs. 12 and 13 are views respectively in front and side elevation of another form of latching-device stop; Fig. 14 is a view in perspective of still another form of stop; Fig. 15 is a view in perspective, similar to Fig. 1, of a somewhat different arrangement and construction of parts.

Referring to the drawings, and particularly to Figs. 1 to 8 thereof, A designates l a transversely-traveling carriage of a fiatplaten typewriter, supported in front by brackets a, carrying rollers or wheels a upon a transverse rail or track (L The rear transverse supporting rail or track is omitted in the drawings for the sake of clearness. Dis- 1 posed upon the top-plate a of the carriage is an escapement or letter-spacing mechanism 1 B, arrangeu to cooperate with a rack-bar C located above the same, for effecting letterspacing of the carriage, which is propelled against the escapement-mechanism by means of a power-spring (not shown) with which connects the drawing tape 6. This letterspacing constitutes the subject-matter of another, co-pending application for patent of mine, filed April 26, 1902, Serial No. 104,843; and, therefore, no claim thereto is made herein, and a detailed description thereof is unnecessary. The said letterescapement mechanism is arranged to be tilted out of engagement with the rack (as shown in dotted lines, Fig. 4) to permit general release, that is, free travel or movement of the carriage in either direction, and I may employ any means for effecting this result. However, I prefer to utilize one similar to the kind herein illustrated; and, to this end, the escapement-mechanism is disposed preferably upon the" transverse rock-shaft b rotatably supported in bearings 6 b, on the top-plate a. The supporting-block I) of said escapement mechanism is provided with a plate 5 (preferably formed as shown), the front edge of which may be extended to form two laterally-projecting arms I), 1), preferably of the form shown, to facilitate action thereon, as presently to be described, to reduce wear and friction. Arranged in front of the said escapement mechanism B, and preferably upon the top-plate a is a tabulator selecting device D of which one member is preferably in the form of a bellcrank lever D, one arm d of which extends inward to a position under the parts I) of plate If; and the other arm d extending vertically, and preferably provided with a thumbknob to facilitate movement of said bell-crank lever. This bell-crank lever D is preferably slidably and rotatably mounted upon a shaft 03 supported in brackets d 61, secured upon, and projecting forward and downward from, the front edge of the top-plate a One end of said shaft (preferably the right end for convenience) is provided with a thumb-piece or turn-nut d to permit a slight rotation of the shaft in its earings to effect an adjustment thereof for reasons as will presently appear. One por tion of said shaft (1 is provided with grooves or ridges d preferably extending spirally along the shaft to effect proper register therewith of a spring-finger or spring-actuated pawl, dog, or the like, oh, constituting a vibrator, disposed upon the interior of a tubular housing or stem (Z connected with, or formed integral on, the bell-crank lever D, and which has, preferably, a depending lug d bent at an angle to the length of the finger or vibrator, as shown in Fig. 7, to insure its proper engagement with the grooves d Arranged on one side of the bell-crank lever D, and free of the shaft (Z is a latchingdevice E constituting the other member of the selecting tabulator device 13*, provided with slots 6, e in which work pins 6 e, projecting from the side of the bell-crank lever D, the said slots permitting a perpendicular movement of said latching-device E upon the bell-crank lever D. Normally, the pins 6 6 respectively rest in the lower portions of the slots 6, 0 as shown in Figs. 1 and 6. The said latching-device preferably comprises two members 6 a one at right angles to the other. t the upper portion of the member a is a pin 6 to which is connected a retractile spring 6 connecting at its other end with a pin or post 6, disposed on the member (2 of the bell-crank lever. The other member 6 extends in a )lane parallel with the member (Z of the bell-crank lever, but is preferably of length less than said bellcrank lever, though of width somewhat greater, so that its upper edge may normally occupy a plane above the upper edge of the member d, the slots 6, e and pins 6 a with the cooperation of the retractile spring 6 permitting this member to occupy said position normally. The particular disposition of member e of the latching device enables this member to constitute the abutment portion. of the tabulator device, since it extends sufficiently high to engage the tabulator stops presently to be described, while it is not so long as to be engaged by the lock for lever D, also presently to be described.

Arranged upon the rail a and preferably in engagement with the rack (1 are one or more tabulator-stops F, which may be of any preferred and appropriate form, such as those illustrated in the various figures of the drawings.

Disposed preferably to the rear of the selecting bell-crank lever D is a toothed plate or locking-rack G, having its lower edge pro vided with teeth or locking-lugs g. This locking-rack G is provided with indentations formed with converging walls which produce the teeth or lugs g. By reason of the walls of the indentations converging, as stated, the tabulatondevice will not only be engaged by said walls, but it will be centered at the point of convergence at the limit of its transverse movement to arresting-position, whereby positive positioning of the carriage is effected and engagement of the escape ment-mechanism with the proper tooth in the feed rack is insured, that is to say, the carriage will be arrested at the exact point to permit the dog of the escapement-rirechanism to engage in the proper tooth in the rack, rather than the next succeeding tooth, so that the carriage is not permitted. to travel to the space beyond that necessary to have the printing effected at the required point.

The said plate is supported at its ends by brackets 9 g preferably formed integral with the plate and bent to constitute securing projections g, g, in which are formed slots 9*, 9 which engage pins g g threaded into the top-plate a this arrangement affording means for permitting adjustment of said toothed plate G. As will be seen, the member 01 of the bell-crank lever underlies this toothed plate and normally is out of contact therewith.

O11 the side of the member (1, opposite to the latchingdevice, extends an indicatorarm 07 parallel with the tubular housing d, and preferably marked with graduation .or scale marks d, preferably corresponding in number to the number of figures embraced in the figure-designation of one million, plus those for the spaces between each group of such designations, the decimals, and those for the cents-designations. This indicator arm extends oppositely from knob (Z whereby the hand of the operator in moving the lever does not obstruct the view of the scale. Disposed contiguous to this scale or indicator is a pointer preferably carried on the top-plate a of the carriage. If desired, I may dispense with the indicatonarm d, and, in lieu thereof, have graduations 9 on the tubular stem or housing (i and dis pose a pointer 12 in juxtaposition thereto, as shown in Fig. 7.

In view of their co-action, it is desirable that the indicator or scale and the bell-crank lever selecting device shall both be arranged relatively on the same support, and the tabulator-stop independent thereof-and the two former may be disposed on a stationary support, independent of the traveling carriage, and the stops be arranged on the carriage in position to engage with said selecting-device, when adjusted for positioning the movable member. For column-work, the unit mark on the scale may be used, thus making a combined tabulator and indicating device.

The operation of this device will be apparent: The operator, having previouslv arranged the series of tabulator-stops h upon the supporting rail a" at the desired points for writing up columned or lined pages or sheets, operates the tabulating selecting-lever D first by sliding it laterally on the shaft (i until the pointer (Z carried by the selecting-lever, registers with the proper point or graduation on the indicator-arm al the spring pawl d automatically checking though not stopping this selecting movement at the several points corresponding to points of carriagestopping. The grooves or ridges on the shaft d, already described, correspond (in their relative pitch and position from each other) to the teeth in the feed-rack that is to say, their measurement is governed by the number and arrangement of the teeth in the feed-rack',there preferably being, say, ten teeth to the inch, and there would, therefore, be the same relative number of grooves or ridges in the shaft. If a greater or less number of teeth are formed in the feed-rack, the grooves on the shaft, the graduations on the scale, and the teeth on the locking-bracket G are made to correspond. The grooves or ridges on the shaft d are arranged, also, to correspond to the several graduation-marks on the scale-arm (1 and assist the operator, by means of said vibrator (Z as she slides the selecting-lever to stop the member at the desired graduation on the indicator-arm d, and are made spiral so that said. shaft may be given fine adjustment by means of the turnnut d to true these grooves up perfectly to an eXactly-corresponding relation to the graduation-marks on the indicator-arm and. to insure the accurate entry of portion d of the tabulator device between the teeth of locking rack G. T he depending lug on the spring-finger or vibrator (i rides over the grooves 0r ridges on the shaft until the pointer and scale register at the desired point.

In the operation of moving the selecting lever D along the shaft cl to select the proper position of the carriage relative to the printing-point, the operator would, preferably, rest her finger or fingers on the bracket d, which thus constitutes a support for her hand, to steady the hand and facilitate the selecting. hen the selecting-lever D is being operated for this purpose, it has not been pulled forward by the operator, but, having located the point, the operator then pulls the lever forward, and this operation will have tilted the member (1 into engagement with the portion 1) of the plate 0", which rocks the letter-spacing mechanism out of engagement with the rack, and this permits free movement of the carriage in either direction to facilitate the positioning of the carriage at a predetermined point, which point has been accurately and quickly effected through the selecting-lever, as just described, when moved with relation to the scale-arm (Z It is to be understood that this operation has positioned the carriage as many spaces in advance of the last numeral in a group of figures as there are numerals and separating marks in that group. In other words, when the operator desires to write, say, 7654.32 for any particular column, she first moves the selecting-lever until the pointer d indicates on the scale-arm d the line for printing the 7. Then she pulls on the selecting lever and thus rocks the escapement mechanism out of engagement, as already described, which puts the carriage under the action of the tape tending to draw the same in one direction. [it the same time, the member d has been caused to engage the teeth in the rack-plate G, whereby said selecting-lever temporarily becomes locked therewith, so long as pressure is placed on the selectinglever. This interlocks the parts and enables the operator to shift the carriage freely, because the escapement mechanism has been disengaged from its rack by means of the selecting-lever (which, for the purpose, has

been utilized as a general release lever). The locking of said selecting-lever in the rackplate G is desirable to enable the operator to move and control the carriage under the action of the carriage moving tape 7), by the selecting-lever without having to take hold of any other )arts of the machine. This position, name y with the lever D tilted into locking engagement with rack-plate G, I call the arresting position of the tabulator device D since this position its abutment portion is disposed to engage with the tabulator stops I Then the carriage is moved until the latching-device I] is brought into contact with the tabulator-stop I which has been arranged, say, in a position to correspond with a particular vertical line on the page, or at a point just beyond that at which the last figure or character of a group will be struck. In the number already referred to, namely, 7654.32 the 7 would be six spaces, say, from the last figure 2. Now, as already described, when the latching device is brought against the tabulator-stop, the car riage is in a position for its printing mechanism to print the 7. 'I he proper position.- ing of the carriage having thus been effected, the selectin -device is released to permit the escapement mechanism to rengage the rack, and then the operator strikes the proper keys to print, first, the "7, and then the remaining figures of the group. The carriage will, therefore, through the medium of the selecting-device, have been properly positioned so as to print this group to bring the last figure 2 inside of the column-lining. The same operation of first selecting on the scale 6 then general release of the carriage, and bringing the latching-device up against a tabulator-stop, and, finally, releasing the hold on the selecting device and striking the keys, occurs for each column. Now, when it is desired to return the carriage to its starting point, that is, to a position to the left of the tabulator-stop, the operator disengages the escapement mechanism 13, and, when the latching-device strikes against the tabulatorstop, it rides over the beveled portion f of said stop, and will yield by moving downward, the slots therein, above described, permitting this operation. The rctractile spring 6 then returns the latching-device to normal position.

Since the latching device operates during the reverse movement of the carriage, I have called it a reversely-operating device. The value of locking lever D against sliding movement on its shaft when the tabulator device occupies arresting position will now be apparent, since, by reason of being thus rigidly locked while it holds the escapement mechanism out of engagement with the spacing rack, it affords manual operating means for effecting carriage-shifting and the latching device permits free reverse movement of the carriage past the tabulator stops, in

spite of the fact that the tabulator device is occupying arresting position during this movement.

In Fig. 15, I have shown a somewhat different construction of the device for effecting the disengagement of the escapement-mechanism from its rack: In lieu of the plate Z2 for engaging the selecting-device, I employ the following elements: Secured to the rockshaft 6 is a crank-arm h, and pivotally connected with this is a link 72, which is pivotally connected, at its other end, to another crank-arm h" secured rigidly to shaft h supported parallel to the rock-shaft b" in brackets 7f, 7r. Rigidly secured upon said rockshaft is a rectangular frame 72 of width c0rresponding approximately to the locking plate G already-described. Now, when the selecting-lever is moved to tilt the member (Z thereof, this member engages and raises said frame, which transmits motion to the rockshaft h, and this, in turn, through the con necting crank arms 72 the link 7L2, and the crank arm 72,, rocks the rock-shaft t and throws the escapement mechanism out of engagement. In this same Fig. 15 and, in detail, in Fig. 8, I have shown a somewhat modified form of a portion of the selecting device: In lieu of disposing the spring-finger i inside of the tubular-stem or housing i I arrange it eXteriorly thereof, and secure it in position by a screw i Its free end is provided with a depending V-shaped portion. i which projects through an opening "i in the stem i and engages grooves, incuts, teeth or ridges t on the shaft. In this form, also, the shaft on which the tabulator operating-lever slides is not rotatable for adjustment; but such adjustment is effected by means of the adjusting screws i which move the shaft longitudinally in its bearings i In this modified form of device, I may, of course, employ the latching-device E on the selectin lever,

the same as upon the construction already ,,j

described, or I may omit it therefrom, as I can, also, in the first-described construction; and, in lieu thereof, employ a tabulator-stop provided with a latching-pawl of any de scribed form. In this construction, bellcrank lever D constitutes a simple bell-crank tabulator device, in contradistinction to which the tabulator device D may be termed a compound bell-crank member.

In Figs. 9, 10, and 11, I have shown the stop F provided with the latching-pawl J, and comprising a body-plate y', through an opening in which extends the shank of a locking-device having at one end a thumbknob j*, and at the other a semi-circular camdisk j designed to engage the supporting track rail a Depending from the plate is a rearward-extending rectangular plate j, provided at its upper edge with a T-shaped portion 3' It is to be understood that the cam-disk is operated to cause its round or curved portion to en the bottom Wall of a groove or cut poi a in the rail c the plate j engaging the teeth a in said member and the T-shaped portion engaging the rear side or" said member to prevent play and disengagiunent of the stop a ter once b ing secured in position. When the thumhuiut turned to bring the fiat portion of the camdisk in e the walls of the groove, the plate 7' is lowe ed out of engagement with the teeth a and ET-shaped portion j is sulliciently lovi "ed to clear the rack teeth in order to permit the device being slipped oil" the rack. This stop is preferahly adjustable on its support, so that its position can be changed at will. Depending from the body-plate j is a dog or pawl J having or ii ":11 depending portion j, pivoted at j", and

Working one direction against a pin or stud j on the body plate to limit its move ment. sp lug j holds the dog normally in engagement with the stud f". In lieu ol' the pivoted pawl or dog, just descriliied, i may provide the lower portion of the body-plate, a. al and 13, with a bore j, invrhich would rlz a plunger carrying a pin 7' working in a slot j in the body-plate, as shown in. Figs. 12 and The lower end of the plun would preferably have beveled face on one side. To hold the plunger normally projected, a spring is arranged in the bore and bears against the upper end of said plunger. it is to be understood that, 1 n the member d oi the bell-crank lever g s the dog Yl, or the beveled plunger 7 no side, it will prevent further movement one carriage fro left to r until the said member d is thr an out or such engagement. f -vlhen the c rriage is being returned to the starting pos .vever, s id memher will. upon striking said dog J, roc-lr. it and pass over the s (and, in the case of the beveled pluug force the same nae-l; into core), and the spring, in both instances,

would return the movable part (dog or p er) to normal position.

the employment oi the latching feature or" the tahulator is not desired, tire form of stop illustrated in Fig. 14 may be used. This form of stop is Without bevel or latching device and would employed in connection W'th the simple form of tabulator device shown in Figs. 11 and It obvious that the form of stop shown in Fig. 14 may utilized with advantage as a lefthand stop for arresting the carriage at any desired lii iit of reverse movement.

it is to he understood .lso applicable to other rorms o'l' Wri lines than that herein illustra veil, to the round-platen style of y pevvriters. 1 latter cla of machines, I would prefer range the tabulatingrdevice, ahpve described, upon a stationery part of the maed, and, as

chine, and the tabulatonstops, With their supporting-rack, upon a movable part, the said tabulatingdevice being arranged to have a connection With the general-release device of the machine.

it is to be understood that, with this device, applied and operated as already described, the usual shock and to the machine, occasioned by the sudden arresting of the carriage upon strihin g the tahulator-stop under full action of the POTTQT spring or driving-device is entirely obviated, as the operator has absolute control of the carriage, and can move the same up to the stop easily and gently. Nhen the bell-crank lever has beermoved first to effect the proper selection of a point on the scale-arm, and then is operated to effect general release 01' the escapement mechanism, and simultaneously engage with the locking rack-plate G, these various parts are all interlocked, so to speak, and can be moved together at the uill of the operator, quickly and gently.

it is to be understood that this device is applicable for doing column-W rk other than merely figures; as, for instance, for Writing names, the addresses, and various other information of parties, in individual columns. W hen. the device is used in this -Way, the calculator-stop would be placed at the proper point for the commencement of the Word or line. Then, by simply operating the selecting-lever until its unit-designation is positioned opposite the pointer, the carriage would he stopped at the proper place to commence the WOICl or line.
