Patented Oct. 11, 1932 ,UNITED STATES PATENT; OFFICE GORDON LAURENCE, OF KEW GARDENS, NEW YORK, ASSIGNOR TO L C SMITH & CORONA TYPEWRITERS INC., OF NEW YORK, N. Y., A CORPORATION OF NEW YORK COPYHOLDER FOR TYPEWRITERS Application filed September 26, 1931. Serial No. 565,271.

Important objects of the present invention are, to provide a simple and. inexpensive Y copyholder of improved design for mounting upon a typewriter carriage, and to provide such a copyholder having improved index means serving as an aid to the typist.

Other objects of the invention will appear hereinafter.

In the drawings, Fig. 1 isa front face view of the copyholder supported by the paper table extension arms of a typewriter carriage;

Fig. 2 a side edge view of the copyholder showing it mounted upon a typewriter carrlage;

Fig. 3 a front view of the mounted copyholder with copy attached thereto and asheet to 3e typed adjusted for typing the first line; an i Fig. 4 a view similar to Fig. 3 showing the sheet positioned with its upper edge in'register with a mark upon the copyholder, indicating that the bottom margin of the sheet has been reached.

The copyholder comprises a rather s tifi' card. The depth of the card equals or slight-' ly exceeds the depth of the copy sheets and the sheets to be typed. A horizontal line 4 printed 'upon the card defines the upper margin thereof. In the left hand margin of the card there is printed a line space scale 5 ineluding numbered double space graduations 6 and numbered intermediate single space graduations'7. At the head of the scale are printed designations 8 for the line space graduations. In the right hand margin of the card there is printed a scale 9 for determining the approximate number of words in typed lines of different lengths. This scale, in the present instance, has fifteen numbered main graduations 10 and intermediate graduations 11 subdividing the Word spaces into six parts. By placing a typed line in register with the scale and observing the number of word graduations included in the length of the typed line the approximate number of words in the line may be determined. The scale has a printed designation 12. I

In the right hand margin of the card there is also printed a bold horizontal line or mark 13. In the present instance this mark is located at the u per end of the scale 9 and above the marl; there is printed a caution legend 14 informing the typist that the last line of the sheet being typed has been written when the upper edge of said sheet reaches the mark 13. Between the scale 9 and the margin line 3 there is printed a vertical line 15 extending from the mark 13 to the bottom of the card. The lines 3 and 15 define a narrow vertical space whose purpose will appear hereinafter.

Near its lower end the copyholding card has two pairs of vertically spaced, rectangular apertures 16 for mounting it upon the carriage of a typewriter. The card is designed for detachably mounting it upon a typewriter carriage C having a paper table T apertures. Thereby the arms and the card' are slightly flexed and their tendency to straighten binds the card to the arms. The arms firmly support the card in an upward] and rearwardly inclined position and wit its lower edge disposed directly back of the upper edge of the paper table. In efiect, the card forms an extension of the paper table and its lower edge abuts stop fingers 17' formed on the mountings of the arms 17.

In the use of the card as a copyholder, the copy, designated 18, is clipped to the u per edge of the card in a position to the le of the margin line 3. Then, the sheet to be typed upon, designated 19, is inserted in the typewriter in initial writing position with its tail portion back of the platen and overlying the copy, as shown in Fig. 3. As the sheet 19 is line spaced, its lower edge 19 recedes down the face of the copy, uncovers the latter line by line and serves as a guide for the typist in reading the copy. When the advancing upper edge 19 of the sheet 19 reaches the receding edge 19 both reaches of the sheet are inserted beneath the copy so as not to obscure it.

The sheet 19 is inserted in the typewriter in a position with its right hand edge slightly displaced to the right hand edge of the copy. WVhen the sheet is inserted beneath the copy, as just described, its protruding right hand margin overlies the card space between the lines 3 and 15, and as the sheet 19 is line spaced its upper edge 19 visibly advances upward along said card space toward the mark 13. The sheet chosen for typing is of a length so related to the vertical position of the mark 13 that when the sheet is line spaced after typing the last practicable line upon the sheet, the upper edge 19 of the sheet will be brought into register with the mark 13. This indicates to the typist that the bottom margin of the sheet has been used, and the sheet, with a proper bottom margin reserved, is removed from the typewriter. If a bottom margin of greater depth is desired one of the graduations of the scale 9 may be chosen for a stop indication instead of the mark 13.

After the removal of the typed sheets the number of lines thereon may be readily determined by registration with the scale 5, and the scale 9 may be conveniently employed for determining the number of words typed.

The card is designed to make it a particularly useful article to authors, editors, copywriters, teachers, students and others whose typing work-requires'uniformitv. When the card is not required it may e readily removed from the typewriter by merely pulling it upward free of the arms 17. The card may bear printed instructions for its use.

What I claim is:

1. In combination, a typewriter carriage comprising a platen and paper table, paper table extension arms carried by the carriage at points spaced therealong and extending upward back of the platen, a copyholder forming an extension of the paper table and comprising a stitl' sheet having a plurality of vertically spaced apertures for each of said extension arms and receiving the latter to detachably support the copyholder in operative position, and an indicating mark upon the copyholder vertically positioned thereon to register with the upper edge of a sheet being typed to indicate that the bottom margin of the sheet has been reached.

2. In combination, a typewriter carriage comprising a platen and paper table, paper eating scale upon one vertical margin of the copyholder.

3. In combination, a typewriter carriage comprising a platen and paper table, paper table extension arms carried by the carriage at points spaced therealong and extending upward back of the platen, and a copyholder forming an extension of the paper table and comprising a stiff cardboard sheet having a plurality of vertically spaced apertures for each of said extension arms receiving the latter to detachably support the copyholder in operative position.

4. In combination, a typewriter carriage comprising a platen and paper table, a pair of paper table extension arms carried by the carriage at points spaced therealong and extending upward back of the platen, a copyholder forming an extension of the paper table and comprising a card having a plurality of vertically spaced apertures for each of said extension arms and frictionally receiving the latter to detachably support the card; a scale printed upon one vertical margin of the card and comprising line-indicating graduationsand numbers, a scale printed upon the opposite vertical margin of the card and comprising graduations and numbers to indicate the number of words in typed lines of different lengths; and an indicating mark upon one of said card margins vertically positioned thereon to register with the upper edge of a sheet being typed to indicate that the bottom margin of the sheet has been reached.

5. A copyholder for a typewriter, adapted to form an extension of the paper table of the typewriter and comprising a card having apertures for receiving extension arms of the paper table to detachably support the card; and an indicating mark upon one of the side margins of the card and vertically positioned thereon to register with the upper edge of a sheet being typed to indicate that the bottom margin of the sheet has been reached.

In testimony whereof I hereunto aflix my signature.

I GORDON LAURENCE.
