My invention relates to tabulator scales or indicators for assisting the operator in performing tabular work on such machines as type-writers, type-setters, printing-machines,

, can be easily and quickly applied to existing I and the like which have a shifting mechanism for operating the carriage when characters of the upper or lower case are to be printed.

The object of my invention is to provide a simple attachment for machines of the abovespecified class which shall be convenient and effective in its operation and shall not interfere with the ordinary use of the machine and machines at small cost. I

The invention consistsof a digital or tabulating scale being attached to the shifting mechanism and in juxtaposition to the scale on the carriage and will be hereinafter more fully described, and specified in the claims.

In the drawings, Figure 1 is a top viewof A a Remington N o. 6 type-writer having for the purpose of clearness the carriage removed and the scale of carriage shown in dotted lines.

Fig. 1 is an end view of reduced'size, showing the relation of the carriage-scale, shifting rail, indicator-stand with digital scale attached thereto. Fig. 2 is an end view of the indicator-stand with digital or tabulating scale attached to shifting rail. Fig. 3 is a plan view of the ordinary indicator-stand provided-with grooves or slots for attaching the digital scale. Fig. 4 is a perspective view showing the back of the digital scale and the spring retaining devices for holding same in grooves or slots on indicator-stand. Fig. 5 is an end view of an indicator-stand having a modified form of digital scale attached thereto. Fig. 6 is aoperspective view of the modified form of scale shown attached in Fig. Fig. 7 is a front view of the scale shown in Fig. 4..

Referring to Fig. 1 of the drawings, 1 is the upper frame-section of a type-writer. 2

is the dust-guard. 4. is the shifting rail. 3 3 are the standards supporting the shifting rail and which are moved back and forth in print ing characters in the upper or lower case. The shifting rail 4: guides and supports the forward end of the carriage 20, the construction and operation of which are fully understood and for the purpose of clearness are omitted on Fig. 1 of the drawings.

5 shows in dotted lines in Fig. 1 and in full lines Fig. 1 the operative position the scale assumes when the carriage is supported on the shifting rail and its relative position between the shifting rail and pointer on indicator-stand.

6 is the indicator-stand attached,'by means of a screw 10, to the shifting rail. (Shown in Fig. 2.)

7 is the digital scale attached to shifting rail or indicator-stand.

15, as shown in Figs. 2 and 3, is the pointer on the indicator-stand, which cooperates with the scale 5 to indicate what point on the paper held in the carriage the next impression will be made.

16 16 in Fig.1 are ordinary clips fastened to the scale to indicate the decimal-points of the different columns to be tabulated and is not essential to my invention and forms no part thereof.

In Figs. 2', 3, and 4 is shown one form of quickly attaching my improvement to the indicator-stand, and consists in providing two slots or grooves M 14, one on each side of the stand 6.- The scale? is provided with two wires 17 1'7, which spring and slide in thegrooves 14 14:, thus firmly holding the scale in place and in such a position as to have the upper edge of scale 7 slightly below the point of pointer 15 on the indicator-stand 6, as clearly shown in end View by Fig. 2..

The graduations on digital scale? are shown in Figs. 6 and 7 of drawings and form'no part of my invention, as they are commonly employed on tabulators of this class of inventions, and consists, starting from the left, of twodecimal places, decimal-point 18, three digital places representing hundreds, comma, three digit places representing thousands, comma, and one representing millions.

If desired, the digital places may be extended; but I have found the above number of digits answers for ordinary purposes. The decimal-point in my scale is made to correspond or be in line with the point of thepointer on indicator-stand.

Figs. 5 and 6 show a modification of the means for attaching the scale to the shifting mechanism, and consists of sheet of metal cut and bent so as to form a scale 7 with pointer 8, and a rectangular bent section 19, having ends 12 and 13, forming a V-shaped opening. To attach this form, one simply unscrews the usual indicator-stand screw 10 and slips the ends 12 and 13 under the screw 10, and have the shoulder and scale properly bent and proportioned to snugly fit the end of the indicatorstand, the point 8 in this case corresponding to the decimal-point and performing the function also of the pointer of the indicator-stand. Thus it will be seen when the screw is tightened the digital scale and indicator-stand are firmly held in place on the shift-rail and making an inexpensive tabulating attachment without disturbing or changing the construction of any of the parts of the type-writer. It will also be readily seen that the hereindescribed digital scale can be used in connection with the many forms of special tabulating attachments for type-writersas,'for example, the device known as the Gorin tabulator-in that the operator can readily see if the attachment has shifted the carriage properly after the depression of a tabulating-key without raising the carriage, simply by 01)- serving or taking the reading on the attached indicator-scale.

The operation of the device is as follows: Having located the point or number on the moving or shifting carriage scale corresponding to the decimal-point on the paper, slide the carriage so as to bring this corresponding point or number on the moving scale to point on decimal indicator or attachment corresponding with the first digit of the amount to be written. For example, if nine hundred and eighty-seven is to be written move carriage until the marked point corresponding to the decimal-point on carriage-scale is opposite to the third digit on the-right of decimal-point on the indicator-scale or tabulating attachment. If one hundred and ninety thousand seven hundred and sixty-five is to be written, the marked point on carriage is shifted to correspond to the sixth place on indicatorscale. Thus it will be seen that tabulating can be readily and quickly effected.

The point on the carriage-scale corresponding to the decimal-point can be marked by a clip or other form of marker; but this is not absolutely necessary to the invention. Thus it will be seen the tabulating-scale or indicator acts as a perfect reading-meter in being in juxtaposition to the scale and shifting with the carriage and at all times in position and in line with the carriage-scale whether the upper or lower scale is being used. Further, the attachment can be readily and with small cost be attached to type-Writers without dis turbing the existing constructions.

What I claim, and desire to secure by Letters Patent, is 1 1. In a type-Writing and analogous machine consisting of a frame, a movable carriage carrying a scale, a shifting rail and a digital scale attached to the shifting rail and in juxtaposition to the scale of the movable carriage.

2. In a type-writing and analogous machines consisting of a frame, a movable carriage carrying a scale, a shifting mechanism for said carriage, a digital scale attached to said shifting mechanism and in juxtaposition to the scale of the movable carriage.-

3. An attachment for type-writing and analogous machines provided with a movable carriage carryinga scale and a shifting mechanism therefor, consisting of a digital scale or indicator having means for fastening it to the shifting mechanism and in juxtaposition to the scale.

4.
