Application filed September 23, 1on9. Serial so. sienna To all whom; it may com-em;

Be it known that I, ALFRED G. F. Kn- ROWSKI, a citizen of the United States, residing in New York city, borough of Bronx, in' the county of New York and State of New York, have invented certain new and Type-VVriting Machines, of which the following is a specifica- Hon. 1 v

- This invention relates to improvements in typewriting machines, and the object is to enable an operatorto conceal the typewritten sheet in. the maclune from the gaze of [urn authorized persons.

A screen is provided so mounted as to en able'th'e operator, to throw it into effective position, or to throwit out of the way when insertingor removing a sheet, or correcting errors. 1

Thep laten frame is provided with an opaque screen adapted, when in one position, to overhang the platen and the sheet to prevent it from being scanned. This screen is capable of being swung upward and tilted backward out of the way, to permit access to the platen. Preferably, supporting arms are arranged to swing with the screen relative to the platen frame to more room.

In the accompanying drawings, Figure 1 is a perspective View showing one form of my invention applied to-the platen of an Underwood type of front strike Writing machine, showing the screen in operative position. Fig. 2 is a fragmentary front view of F ig. 1. Fig. 3 is a cross-sectional View showing the screen in concealing position, dotted lines showing the positions of the screen when tipped backward to permit the correction of errors. Fig. 4 is a cross-sectional vlew showing the screenswung backward out of the way.

A platen A has an axle l journaled in a platen frame 2, which also carries the usual paper shelf 8. The paper 15, is usually fed into the machine between and platen, and is held in place by the fingers and guides 5. To supports 6 is pivotally secured a concealing screen 7. This screen projects forwardly and downwardly to a point just above the printing pointand in front of the platen, overhanging the latter, asshown in Figs. 1 and 8, so that the writing is concealed. The operator can continue. writing, the paper being fed upwardly give the operator the paper shelf form a passageway 17 The screen 7 is partly supported by rests 8 on the supports 6 forward of the pivotal supports 16 of the screen 7. i

' Preferably, I pivot the supportsfi to the platen frame, as at 11, to permitthein to be thrown backward, as shown in dotted hues in Fig. 3, together with the screen 7, to pen mit the operator to make'erasures,-botlr the screen and" the supports moving about the pivots 11, and the forward or lower edge of the screen being raised suiiiciently to permit play of the operatorshands between the same and the platen.

In operation, the screen and its supports are first thrown back on thepivots l1 and 16, as shown in Fig. 4, wherein the screen forms an extension of the paper-shelf 53, the rearward extension 9 of the screen engaging the curl 10 of the paper-shelf. In thisposition, the screen forms an extension of the paper shelf andfacilitates the insertion of The operator supports forthe sheet into the machine.

then swings the screen and its wardly on the pivots 11' and 16 to theposition shown in full lines-in Fig. 3, with the screen concealing the paper as it issuesin front of the platen and travels upward-and backward through the passageway 17. If it:

is necessary to make correctirms, the screen and its supports are swung together on the lines .in Fig. 3. To remove the sheet, the screen and supports are swung backward to the position shown in Fig. 4.-.

- If desired the supports may be rigidly secured to the platen frame instead of being pivoted thereto.

The supports 6 have stops 12 and '13, and

The platen coperates' paper advances towardpivots 11 to. the position shown in'dotted the supports may be connected by a brace 14;.

It will be observed that the supports and brace constitute a frame for supporting the screen, and that the; shiftable screen is capable of being swung from its concealing position, to partially or wholly uncover the platen and paper carried thereby.
