This invention relateslto attachments for typewrite s and particularly gdevices for, handling the paper in atypewriter,and intparticular a graduated paperplatform with flanged edges hin ed to the: ,paper table. of, theigtypewriter and supported by a brace -hingedly attached, to the mar- .gin.-bar1thereof-.-;- I

The "purpose o f thi s invention is to facilitate spacing-and aligning-paper in-a typewriter and to provide means for holding the paper wherein AEGINFINDIGAEO att wrnm a,Manhattan-1t o.

With this thought in mind this invention comtemplates a. simple, inexpensive, effective attachment for a typewriter with which it is possible for the typist to have visibility of the entire typewritten matter on the sheet being typed, enabling ready reference to any part or to all of the typing on the sheet, and to provide a positive, visible, accurate means of indicating the amount of margin at the top and bottom of the sheet at any time, enabling the typist to neatly and artistically arrange typed matter on the sheet, maintaining any desired or specified margins, and making it possible to type a plurality of sheets with the same margins.

The object of the invention is, therefore, to provide an attachment for typewriters and the like in the form of a graduated platform that may readily be installed on machines now in use as well as provided as standard equipment on new machines.

vFigure {lis a plan view o f the 'platform showing she t paper themes-w th ae t bre en awa andwithzpartswomitted, t t, .a, Figure, 5 similar View showi g only the central portion of the platform with the ends and the typewriter attachment of this invention includes a platform 10 supported by a bracket II with the platformpivotally mounted on the typewriter paper table IZand the bracket mounted on the margin bar I 3.

The platform is" formed with flanges I4 and I5 at the sides and hubs l6 and I! are provided on projections laand H! at the lower corners as shown in Figures 4'and 7. The lower edge of the platform is formed with a roll 20 and clips 2| extend backward from the intermediate part The face of'ithe'platform is provided with a medial line 22 having graduations 23 on one side and 24 on the other. The graduations 23 are provided with a column of numerals 25 with the letter B at the upper end indicating the position of the lower end of the paper with the upper end on the aligning scale, as shown in Figure 4, and also a column of numerals 26 with the letter T at the upper end indicating the number of inches from the top of the paper the typing will be located with the lower end on the graduation. The graduations 24 are also provided with a column of numerals 21 headed by the letter B indicating the number of inches the typing will be from the bottom of the paper with the top on one of the graduations, and also a column 28 with the letter T at the top indicating the number of inches the typing will be from the top of the paper with the top on one of the graduations.

In mounting the platform It on a typewriter the hubs l6 and I! are pivotally attached to a roll 29 on the upper edge of the paper table 12 by pins 30, as shown in Figure 6, whereby the platform is free to fold downward upon the upper surface of the typewriter as shown in dotted lines in Figure 1. The bracket ll which is formed with downwardly extending ends 3| and 32 having offset portions 33 and 34 therein is pivotally attached to the margin bar l3 by clamps 35 and 36 as illustrated in E'iguresZand 8, and when in the operative position the horizontal bar of the bracket is inserted under the clips 2| so that the bracket supports the platform. The upper end 31 of the bracket is bent so that it is parallel with the platform and also so that it will fold to a position against the back of the typewriter as shown in dotted lines in Figure 1. The offset portions in the ends of the bracket permit the clamps 35 and 36 to be located beyond the extreme positions of the marginal bar stops.

, With the parts arranged in this manner the paper will be supported in an upwardly inclined position at all times and the paper and all typing thereon is visible continuously. All guess work in aligning the paper or margins, or in spacing the .typingfrom the upper or lower edges of the paper is eliminated. The flanges at the sides guide the paper at all times. The paper may readily be inserted. in the machine and. may be squared by a line 38 that may be extended across the upper part of the platform.

It will be understood that modifications may be made in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is: g

1. An attachment for typewriters comprising a paper platform, means hinging the lower edge of the paper platform to the upper edge of the paper table of the carriage of the typewriter whereby the paper platform is adapted to move to substantially a horizontal position on the typewriter, said platform having 'graduations thereon indicating relative positions of paper in the typewriter, an inverted U-shaped bracket position behind the platform; means pivotally clamping the lower ends of the bracket to the carriage whereby the bracket is adapted to fold downwardly to a position against the rear of the typewriter, and means removably attaching the upper edge of the bracket to the platform.

2. In an attachment for typewriters, the combination which comprises a paper platform with flanges at the sides and clips extending from the rear thereof, said platform havinghubs on projections at the lower outer corners thereof, pins pivotally attaching the platform through the hubs to the paper table of the typewriter, a bracket with offset downwardly extending ends with the upper part thereof adapted to coact with the clips of the platform to support the platform in an upwardly inclined position, and clamps pivotally mounting the bracket through the ends thereof on the margin bar of the typewriter.
