TYPE-WRITING MACHINE Specification of Letters Patent.

Patented Oct. 4, 1910.

Applicationfiled April 8, 1909. Serial No. 488,675.

respectively, at'Helgolandsgade No. 16, and

Sofievej No.12, Copenhagen, Denmark,l1ave invented a new and useful Improvement in Type-WritingMachines;- and we do hereby declare the following to be a full, clear, and exact description of the same.

Our invention-relates to typewriting'machines and more particularly to tabulating mechanism.

'In tabulating mechanism heretofore employed it has been customary to use a column stop rod or rack with a notch for each indeX on the carriage scale or for each letter space position of the carriage in its line of travel. Column stops were ordinarily adjustable along the stop rod or rack, being seated in different notches and arranged for cooperation with one or more tabulating stops so that when the carriage was released certain of the tabu'lating stops would cooperate to arrest it. In the use of such adjustable column stops considerable time was required to set them or adjust them when a change from one character of work to another was made, and the work involved determining where to set the stops was somewhat troublesome.

Oneof the main objects of the-present invention is to overcome these difficulties and to provide comparatively simple and efficient mechanism for quickly determining the proper positions of arrest of the carriage and for readily setting the tabulating mechanism accordingly.

A further object of my invention is to provide means. for readily clearing all of the previously set stops, when the work is such as to require the use of differently arranged stops.

To the above and other ends which will hereinafter appear, our invention consists in thefeatures of construction, arrangements .of parts and combinations of dev ces to be hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicate corresponding parts in the various views, Figure 1 is a vertical, central, fore and aft sectional View, of oneform of typewriting machines embodying our invention, only so much of the machine being shown as is necessary to illustrate the invention in its embodiment therein. Fig. 2 is a plan View of the same. Fig. 3 is a detail top view, partly in sec tion, of the stop carrying rod, the stops carried thereby and the clearing bar. Figs.

4 and 5 are transverse sectional views of the same.

In the present instance 'we have shown our invention embodied in a No. 11 Remington machine which contains a decimal or denominational tabulator.

carriage in the usual manner which travels across the top plate from side to side of the machine and is provided with arms I) which carry a stop rod or bar 0 provided with column stops (Z. During the travel of the carriage the stop rod 0 is moved with the carriage carrying the column'stops past the denominational stops e, only one of the denominational stops being shown. The stop rod 0 is hollowand its front and rear walls are provided with narrow apertures or slots, each registering pair of which corresponds to a letter space position of the carriage or to one of the indices on the scale. stops (Z, preferably equal in number to the slots in the stop rod, are inserted in said apertures in the stop rod and may be pushed forward or backward therein but are held in the forwarder backward position to which they are moved by suit-able friction springs f as indicated in Figs. 4 and 5.

At one side of the denominational keys of the tabulator, or in some other convenient place, is arranged aspecial projecting key g by means of which itis possible to push rearwardly or to project to the operative 'position, any of the column stops (Z depending on the'letter space position of the carriage when the projecting key 9 is actuated, so that the position of the carriage determines ,thp selection of the column stops and the COllUl'lHnI' position inwhich the carriage may afterward be arrested by the co operation of the denominational stops 0 with the projected or active column stops (1. In

Column end of the lever n orms what may be termed a projector or finger p which is in substantial alinement fore and aft of the machine with the first or left-hand one of the series of denominational stops e as shown in Fig. 2. The travel of the carriage brings the column stops d successivel into register with the finger p and renders t e finger operative on the column stop which happens to be in register therewith when the key 9 is depressed. Thus pressing down the projecting key 9 brings the finger p into engage,- ment with and pushesthe column stop (1 in 'front of the finger rearwardly into active or operative position where it is maintained by its friction spring 7. The projecting key 9 andthe finger p are returned to normal position by a'spring r. In Fig. 2 8 indicates one of the column stops which has been pushed into its active or opreative position'while all the rest of the column stops shown in this view are in inoperative position. The returning of the column stops to inactive position can be effected in various ways. A simple and efiicient form of mechanism for accomplishing this purpose is shown in the drawings. In this construction each of the column stops at has a square opening 0 extending therethrough. A clearing or restoring rod or bar it extends through the openings 12 in the series of column stops and is rounded at its ends to form pivots which turn in bearings in the ends of the hollow stop bar 0 so that the clearing bar at is enabled to turn on its longitudinal axis. One end of the bar it extends beyond the end of the hollow stop bar where it is provided with a thumb button or finger wheel t by-means of which the clearing rod canbe turned. The rod u is normally turned on its pivots to the position shown inFigs. 3 and 4, owing to the action of a coiled spring m which surrounds the rod near one end thereof and has one end connected to the clearing rod or bar a and the other end connected to the 7 different character of work, requiring the hollow stop bar 0. When the clearing bar is in the normal position any of the column stops can be pushed into active or operative position by the finger p and may continue to move rearwardly until the forward wall of the opening 1; in the-stop d meets the forward edge of the clearing rod it, thus limiting the stroke of the stop.

. From an inspection of Fig. 3 it will be seen that that portion of the bar it with which the column stops cooperate is fiat and is off-set from the axial center of the clearwhee 15, the eccentric edge or portion of the clearing bar or rod will contact with the forward 'walls of the openings 1; in all of the columnstops which have been moved to operative position and will clear" or move all of such stops back to inoperative position as indicated in Fig. 5. If the thumb wheel tis then released the rod u will be returned by the spring to to normal position independently of the column stops 0? as shown in Fig. 3.

In use it may be assumed, for instance, that a letter is to be written in which vertical rowsof names and amounts are to be written, which names and amounts in the different lines are to be placed exactly under each other. It is only necessary when the carriage is moved to the position where the first letter of a name or the like is to be written, as at l5 on the carriage scale, to press down the key" 9. This moves the column stop d at l5 which is opposite the column stop projecting finger 3; into operative position and thereafter during the tabulating operation the projected column stop will co-act with the decimal stop 6 at the same point 15 in the travel of the carriage where the c rriage was arrested to select the column top and in the desired position Where the name is to be started. If the operator desires to set a column stop to Write, for instance, an amount in the same line at, say, 55 on the carriage scale, it

is only necessary, in a decimal tabulator, to

press'down the key 9 when the carriage is found at the point where the decimal point is to be Written at '55 on the carriage scale. This projects a column stop at 55 to arrest the carriage at such position when the decimal key is depressed. If in the next and subsequent lines a name and amount are to be-written exactly under the first ones no further setting of the stops is required and only those column stops are eiiective which have been moved to the operative position by the actuation of the key. 9 in the manner described.

.When the tabulatoiis to be set for a be moved to normal position by the spring as. The new column stops may then be individually selected and projected to operative position as before.

It will be understood that an essential ad- 'antage of the device is that the column stops are, by pressure on the key 9 individually setup while writing the first line,

so as to avoid calculating beforehand the positions where the stops are to be set or positioned, the position of the carriage in the present structure aiding in determining theselection ot' the column stop to be used for that particular point of arrest.

The construction described shows but one example of, a construction embodying our invention and different details can be varied without departing from the spirit of the invention. i

One of the characteristic features of the invention is the provision of a stop for each index on the scale or for each letter space position of the carriage; or at any rate for 209 each index on the carriage scale or each letter space position of the carriage where ordinarily such stops would be employed and the provision of means whereby each of said stops can be thrown into and out of operative position.
