ful Improvements in Spacing Mechanism for Type -Writing Machines, of which the following is a full, clear, and exact description.

Type-writing machines of the most modern styles may be divided into two general classes,

in one of which the carriage or support for the paper is movable with respect to the printing mechanism and in the other of which (commonly called book type-writers) the sheet or book to be written uponis mounted upon a stationary support, while the printing mechanism is movable with respect thereto, and in both of these styles of machines an escapement mechanism is interposed between the fixed and movable members in order to permit the step-by-step movement in the direction of the line of print. Both of these types of-machines have heretofore been provided with devices whereby the movable mem- 2 5 berfor example, the paper-carriage-after being released from the control of its escapement mechanism is permitted to run free or to be moved manually until arrested by the cu gagement of a dog or arm with a series of soo called column-field stops arranged at'deo all of these prior devices, however, the operative relation of the parts has been such thatwhen the carriage or movable member was allowed to run free it would necessarily engage the first and thereafter successively the 5 remaining column-field stops whatever their number might be. In certain classes of typewriting work, in whichit is desired to employ a numberof column-field stops for defining a plurality of columnar fields upon the sheet to be printed, it often happens that in certain of the lines of writing no entry is required in the first one or perhaps, the first several of the columns or fields, the entry or entries being made only in the last one or more of the predetermined columns.

All prior constructions of columnating apparatus have been subject to the objection that under all conditions the carriage or movable member when released from its escapement was necessarily arrested at the first and at each succeeding column-field stop until it finally reached the stop at which the desired entry was to be made.

Our present invention has for one of its objects to overcome this objection, and this feature of the invention consists in providing a series of column-stops or other suitable means whereby a series of columnar positions or fields ranged along the entire line of print may be defined or produced and in providing in connection therewith column skipping mechanism by which the carriage or movable member may be released from its escapement and arrested at a predetermined one of the columnar positions or fields without being temporarily checked by the first or intermediate column-field stops, as with prior devices, the carriage or movable member thus skipping, as it were, all the column-fields between its starting-point and a particular one at which the desired entry is to be made.

Type-writing machines have also been heretofore equipped with so-called tabulating or denominational-stop mechanism,whereby the carriage or movable member when released from its escapement is allowed to run free or to be moved manually to any one of a group of several positions determined by a group of stops arranged at letter-space dis tances apart, these last devices being more especially designed to permit rows of figures to be printed in proper denominational order, one beneath the other.

A further objectot our invention is to provide an improved construction oftabu'lator mechanism of the type last described.

A still further object of the invention is to provide an apparatus embodying in combination a columnating mechanism whereby the paper-carriage or movable member may be arrested at a predetermined one only of a series of column-fields ranging across entire line of print and tabulator or denominationalstop mechanism whereby the orderly printing of rows of figures or the like may be effected.

With these several objects in view the invention consists in the features of improvement and novel combination of parts hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the claims at the end of this specification.

Figure l is a view in vertical section on line 1 1 of Fig. 3 through a type-writing machine having our invention applied thereto. Fig. 2 is a rear elevation of the machine with parts broken away. Fig. 3 is a plan view, parts being broken away for better illustration. Fig. 4 is a view in horizontal section on line 4 4t of Fig. 1. Fig. 5 is a detail perspective View of a stationary frame forming a part of the improved apparatus. Fig. 6 is a perspective View of the shifting frame, and Fig. '7 is a detail perspective view of certain locking devices hereinafter described.

The particular form of the invention hereinafter described being more especially designed for that class of machines in which a movable paper-carriage is employed, it has been deemed necessary only to illustrate such style of machine; but as certain broad features of the invention are manifestly applicable to other styles of machines it is not intended that the claims hereinafter made should be understood as limited to a machine of the type shown.

The main frame A of the machine may be of any suitable form, and the carriage B may be mounted thereon in any convenient manner, this carriage being shown as furnished with the usual platen G, whereon will be supported the paper to be printed. As shown, thecarriage B,which is of the familiar Remington style, has connected therewith a rackbar D, with which engages a pinion E, the shaft of this pinion being mounted in a stationary bearing 6, this rack and pinion forming part of the usual escapement mechanism whereby the step-by-step feed of the papercarriage is controlled. The rack D is provided with rearwardly-extending arms that are pivotally connected in the usual manner, as at i, to lugs depending from the rear bar of the carriage B, and a suitable coil-spring serves to hold the rack D in normal engagement with the pinion E. The rack D will be provided with the usual mechanism, (not shown,) whereby it may be raised from the pinion E when it is desired to move the carriage in either direction independently of its escapement mechanism. The top A of the main frame is formed with the usual circular opening, around which will be grouped the type-bars whereby the printing of the paper on the platen C will be effected. To the back bar of the carriage B is suitably connected the rearwardly-projecting arms L, these arms being shown as provided upon their front ends with depending lugs *F, that straddle the back bar of the carriage, and with vertical lugs i through which pass the set-screws g, adapted to bear against studs b rising from the back bar of the carriage through openings in the front ends of the bars L. Manifestly, however, the bars L may be connected to the carriage in any other convenient manner. The rear ends of the bars L carry a column-stop bar K, that is preferably connected to the arms L by setscrews it, that pass through slots h formed in the rear ends of the bars L, the purpose of these slots being to permit an accurate adjustment of the column-stop bar with respect to the letter-space mechanism of the machine. Upon the bar K will be suitably mounted suitable means, such as stops, for producing or defining a series of columns and which will cooperate with the dogging means and with the denominational contacts or plunger-s to be presently described. In the preferred form of the invention the bar K is formed with serrations or notches arranged at letter-space distances apart and adapted to receive adjustable column-field stops f, cooperating with the dogging means, and denominational columnstopsf cooperating with the denominational plungers. Preferably but not necessarily these two sets of stops consist of contact parts or projections upon the combined columnfield and denominational column-stops f, located when the latter are in position on opposite sides of the column-stop bar K. (101- umn-stops f are thus adapted to be adjusted along the column-stop bar K to define colu m n-fields at variable positions along the line of print and are adapted to be held or set in adjusted position.

By reference more particularly to Figs. 1 and 2 of the drawings it will be seen that the column-field stops f are graded or stepped, so that these stops stand progressively at dif ferent points with respect to the dogging mechanism with which they will engage.

Beneath the main frame A of the machine extend a series of push-keys F, the front ends of which are provided with finger-pieces and are mounted in manner free to slide within a bar G, that may be conveniently attached to the base of the main frame, as clearly shown in Fig. 1, by lugs that carry set-screws a. In the drawings (see Fig. 4) six push-keys F are shown, these keys being numbered, respectively, from 0 to 10,000, although manifestly any desired number of such keys may be employed. The rear ends of the keys F are pivotally connected, as at 9, to the .lower forwardly-projecting ends of a corresponding series of levers H, the upper ends of which levers are pivotally mounted upon a rod 17, that is journaled in the front portion of a stationary frame I. This frame I is preferably constructed as shown, reference being had more particularly to Fig. 5 of the drawings, in which the lower part of the frame I comprises side bars I, having inwardly-extending lugs 01, adapted to rest upon the back of the main frame and having at their eX- h 1 ifs I cap-plate P. The upper ends of the bars the keys F F.

mainframe and are clamped thereto by suitable set-screws 0. (See Figs. 1 and 2.) Within shown, consists of side bars 0 O, that are united by crossbars m m and by a slotted set between the arms n n of the frame I, the

of the bars 0 of the shifting frame is extended downwardly, and to its lower endis pivotally connected the rear end of a supplemental push-key or shift-key Q, the forward end of this key Q passing through the plate G and being provided with a finger-piece similar to Each of the keys F and as well also the shift-key Q is shown as retracted by a coil-spring T, one end of which is connected to thefront bar G, while the opposite end is attached to a lug t, fixed to the corresponding key. (See Fig. 1.) Upon the cross-bars mm.

of the shifting frame is mounted a plate R,

carrying at its upper end an arresting device or stop-dog q, which, as shown, is bent rearwardlyor in offset relation to the plate B, so as to stand normally out of the line of travel of the column-field stops f above it. The

plate R is formed with slots 0" and r, through which pass the headed screws p, respectively, (see Figs. 1 and2,) whereby the plate 1 is held in manner free to slide upon the crossbars m m of the shifting frame. A coil-spring S,connected.atits upperend to the angular portion of the plate R and at itslower end to the head of the screw 1), (or other relatively fixed part,) serves to hold the plate in the normally I retracted position shown in the drawings.

To each of the levers H is pivotally connected y the lower end of a plunger J, the upper ends a cap-plate P and stand normally beneath the of these plungers passing through the slotted path of travel of the denominational columnstops f vention the plungers J perform the double function of operating the plate R to bring its dog q into engagement with the contact parts f of the column-stopsand of bringing the upper ends or contact parts of the plungers into engagement with the stops f when columns of figures are to betabulated; but manifestlyif the columnating mechanism of our invention alone is to be employed the upper ends or denominational contacts of the plungets and the stops f maybe omitted. In the preferred embodiment of our invention a variable movement is imparted to the dog q in order to bringthis doginto proper position for engagement with a predetermined one of the set of stopsf above it and to enable the dog toskip theintermediatecolumn-stops. Pref- In the preferred form of this inthe plate R (see Fig. 2) with a'series of graded steps R, these steps corresponding in number and arrangement with the correspondinglygraded stopsf. Each of the plungers J is formed with a ing or offset J, that is arranged beneath the corresponding step or shoulder R of the plate R. Hence it will be seen that when either of the plungers J is raised its lug J will contact with the corresponding step or shoulder of the plate It and lift the plate into position to engage the contact part of one of the column-stopsf. Inasmuch as the lugs J of the plungers are in horizontal line, it will be seen that with certain of the plungers there willbe lost motion until their lugs J have been raised far enough to strike the steps R of the plateRabove them. Hence it will be seen that a varyingextentof movement will be imparted by the plungers to the plate R, and consequently to the dog q, and the effect of this will be to cause the engagement of the dog with a predetermined column-stop, as will presently more fully appear. In the drawings the column-stop bar K isshown as provided with but four columnfield stops, and consequently only four of the plungers J are shown as provided with lugs or offsets J, (the corresponding keys being designated by numerals l to 4,) although if more column-field stops are desired others of the plungers J will be provided with offsets and additional steps R will be added to the plate R. In this manner column-skipping mechanism is provided by which the carriage is released and the stop-dog actuated to engage a predetermined column-field stop and bring a predetermined column to the printing-point.

The release of the paper-carriage from its escapement mechanism in order to permit the carriage to run free until arrested by any predetermined column-stop is preferably effected by the mechanism next to be described. Pivotally mounted, as at 00, between the arms 0 of the swinging frame isa bell-crank lever N, the rear portion of which comprises two arms united by a bail or cross-bar N. The front armof the bell-crank lever is pivotally connected by a link a," to a releasing-bar M, that is pivotally mounted upon a bracket M upon the top plate of themain frame. This arm M is furnished at its forward end with a shoe Z, having an opening therein to set over the pinion E, (see Fig. 3,) and when the shoe Z is lifted in manner to be presently described it will contact with the lower edge of the rack D and lift the rack from engagement with the pinion. Each of. the plungers J is provided upon its front edge with a lug or offset F, which when the plungers are raised from normal posit-ion to the position shown by dottedlines in Fig. I will contact with the crossbar or bail N of the elbow-lever N, thereby rocking this lever and caus-' ing it in turn to rock the releasing-lever M, so as to effect the disengagement of the rackbar D from the pinion E and so permit the paper-carriage to be drawn forward by its propelling spring independently of the escapement mechanism.

From the foregoing description the operation of the parts will be seen to be as follows, the operation of the column-field-stop mechanism being first described: The operator will first arrange the several stopsfat positions upon the bar K in keeping with the number of predetermined points along the line of print at which the carriage is to be arrested. If then it is desired to print at the extreme right-hand side of the sheet in the fourth column-field,(for example, a date,) the operator will force inward the shift-key Q and at the same time also the push-key F, No. 4, adjacent the shift-key Q. The effect of moving inward the shift-key Q is to cause the swinging frame 0 with parts carried thereon to turn about its pivot-points K, thereby moving the dog q and the plungers Jfrom the position shown by full lines to the position shown by dotted lines in Fig. l. The dog (1 is thus brought into the plane of travel of the column-field stops, while the upper ends of the plungers Jare moved from the path of the stops f". By reference to Fig. 2 it will be seen that the operation of this particular push-key will lift the correspond ing plunger J, the lug J of which is beneath the extreme right-hand step or shoulder R of the plate B. As the plunger J is lifted, its lug J will contact with the bail or bar N of the elbow-lever N, thereby causing this lever to rock the release-lever M until its forward end raises the rack-bar D from engagement with the pinion E, thereby permitting the paper-carriage thus freed from its escapement to be drawn rapidly toward the left. Inasmuch as the plunger J must move a considerable distance before its lug J contacts with the corresponding shoulder B, it follows that the dogq will be lifted by the plunger a sufficient distance only to enable it to engage the column-field stopf of the columnstop f at the extreme right of the carriage, the dog thus skipping or escaping the column-field stops intervening between it and the column-stop at the extreme right. If upon the next line to be printed it is desired to stop, for example, at the second columnfield stop from the left-hand end of the carriage, the operator will push inward the shiftkey Q in manner above described and at the same time will force inward the third pushkey F, No. 2, therefrom. The effect will be to lift the dog q sufficiently high to engage the second column-field stop f from the left-hand end of the carriage, but not high enough to contact with the column nearest such end. It will be seen that by means of our improved columnating mechanism the carriage is released and arrested at any one of a series of positions arranged along the entire line of print and predetermined by the adjustment of the column-field stops on the carriage instead of having the carriage arrested by the first and each succeeding column-stop, as in the prior constructions. This provision of means whereby the carriage may run uninterruptedly until it reaches the predetermined one of a plurality of columnfield stops is a marked advance in the art, as it very materially saves the time of the operator. In a preferred modified form of this columnating mechanism to insure certainty of operation we provide means for locking the operating parts after they have been moved from the normal, and whereby both are subsequently unlocked, preferably, when the selected column-stop upon the carriage engages the dog, so that the operator need only actuate the proper key, but need not keep his finger upon it.

The locking devices are illustrated in Fig. 7. A bent spring-catch 10 extends parallel to one of the arms 72 and is adapted to engage a lug 11 on the swinging frame 0. The lug 11 has an inclined and an abrupt face, so that the frame 0 may be readilyswung inwardly by the shift-key Q, but will be locked in such inward position as the spring-catch 10 engages the abrupt face of the lug 11. The slot r in the plate B, through which passes the pin 19, is enlarged laterally, so as to permit not only a longitudinal movement of the plate R, but also a certain amount of lateral play to the upper end of the plate R and to the dog (1 attached thereto. The plate R and dog q are urged toward the right of the machine by the spring-catch 10, the end of which engages a projecting edge portion of the plate R. The opposite edge of the plate R is provided with a series of ratchet-teeth 12, (in this case four,) corresponding to the steps R and the various positions into which the plate R and dog q are raised by the plungers J. Secured to the adjacent arm n of the frame I is a stripspring catch or pawl 13, which slides over the teeth 12 as the plate R is moved upwardly, butwhich engages one of the ratchet-teeth and locks the plate R and dog q in the position to which they have been raised by the selected one of the plungers J. The carriage will be released, as above described, when the plunger J is actuated, and will be drawn toward the left by its main spring until the selected column-field stop f engages the dog g, which will then be forced slightly to the left, disengaging the plate R from the catch 13 and disengaging the catch 10 from the lug 11 and the parts will be returned to the normal, the plate R by the spring S and the frame 0 by the spring T on the shift-key Q. These locking devices insure certainty and accuracy of operation and obviate the necessity of holding the shift-key Q in its inward position while the proper key F is being pushed, or, in other words, the shift-key Q and the selected push-key F may be actuated in succession, and it is not necessary that they should both be actuated simultaneously. Such locking devices we believe to be broadly new as applied to tabnlators and may be used with the ordinary forms of such spacing devices other than the special form herein set forth for the purpose of relieving the operator from the necessity of holding the actueach other in vertical lines.

movements of the carriage, and as there are six of these, plnngers shown it is obvious that these plungers allow for the writing of five digits anda decimal-point in the field defined by any column-field stop. Thus, for example, if by the operation of the shifting-key Q and one of the push-keys F the carriage is allowed to run freely toward the left until his arrested by a predetermined one of the column-field stops and it is then desired to write a series of digits constituting a number at such point the operator will release the shiftkey and the push-key, thereby allowing the paper-carriage to rengage its escapement mechanism and the frame 0 to resume its normal position. The operator will then press inward the push-key F corresponding to the denomination of the left-hand digit of the number to be written and the carriage will be again released and run free until the denominational contact partf of the adjacent stop. engages the upper end of the plunger corresponding to the key forced inward. Thus, for example, if the amount 54.62 is to be written in, say, the last column at the right-hand side of the page the operator will move the shift-key Q and the next adjacent push-key F No. tin manner above described, thereby allowing the carriage to run free until the dog q engages the fourth column-field stop 1 at the extreme right-hand side of the machine. The operator will then release the shift-key and the push-key to permit the escapement mechanism to rengage the paper carriage and thereafter will force inward the push-key F beneath the denomination 10,

thereby allowing the figures and decimalpoint 54. 62 to be Written in proper position.

As the operation of this part of our invention will be readily understood by those familiar with the well-known Gorin tabulator, it need not be more fully described.

It is obvious that this part of our invention, however, may be employed independently of the columnating mechanism last, described, although from what has been shown it Will be seen that the devices when combined afford a most effective spacing apparatus without increasing to any considerable extent the number or cost of the parts.

While we have described what is regarde The plungers J are arranged at dis,

as the preferred embodiment of the invention and have shown it in connection with but one type of machine, it will be understood that without departure from its spirit or scope the invention can be modified within wide limits and can be adapted to machines of other types. Thus, for example, other forms of stops may be su bstituted for the combined column-field and denominational column stops shown, the term column-field stops as used in the following claims being designed to include any stops that serve to cooperate with suitable dogging means to locate a predetermined one of a series of columnar positions or fields along the entire line of print and each comprising multiple letter-spaces, and the term denominational column stops to include any stops that will serve to cooperate with suitable means to select one of a seriesof letter space positions, whereby the series of numbers will be written in proper denominational ordert'. 6., in the units, tens, hundreds column, the. The term columnating mechanism as used in the claims is desired to be understood as indicating the mechanism by which the column-field stops are brought into operation, and by the term .denominational-stop mechanism the mechanism whereby the denominational stops are properly operated. Further, other devices could be substituted for the variably-movable with the denominational column-stops to perform the assigned functions of these parts.

Having thus described our invention, What we claim as new, and desire to secure by Letters Patent, is
