TYPEWRITING MACHINE.

Application filed February 1, 1921. ,Serial No. 441,523.

T 0 all whom it may concern:

Be it known that I, CHARLES M. HILSEE, a citizen of the United States, residing in Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the'following is a specification.

This invention relates to a device for facilitating the insertion and typing of several varieties of work-sheets, such as gas or electric bills of the type which require but a single line oftypewriting. In such cases it is unsatisfactory to insert each work-sheet from the rear, since a great deal of time is consumed in adjusting each sheet to the printing line.

The present invention is shown as applied to or embodied in an Underwood standard typewriting machine, and provides a simple means comprising a shield or auxiliary paper-apron which may be formed from a single piece of suitable sheet material, as, for example, strong paper. This auxiliary paper-apron isprovided with a forwardly and downwardly turned front marginal part forming a fold to engage over and cover the sharp or broken front edge of the usual paper-apron, and thus provide a smooth, unobstructed path for a bill-sheet inserted from the front of the machine. The auxiliary paper-apron overlies the usual or main paper-apron, and may be clamped at its rear end to the usual rear paper-table. The auxiliary paper-apron covers the openings commonly provided in the usual paperapron, for the usual feed-rolls, so that a front-inserted work-sheet cannot catch upon or be fouled by the edges formed by said roll-receiving openings.

Since but a single line is to be typed, it is not necessary to feed the bill-sheet. When another bill-sheet is to be typed, the typed bill-sheet is removed, and another bill-sheet inserted. The operation is extremely simple and permits rapid and eflicient handling of bill-sheets of the variety described above.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a perspective view of parts of a typewriter carriage with the invention applied thereto.

Figure 2 is a vertical section of the mechanism shown in Figure 1.

Figure 3 is a detached view of the auxiliary paper-apron.

A carriage platen-frame 1 is provided with a platen 2, fixed upon a shaft 2*, journaled in the carriage end walls 3, said platen-frame having a rear paper-table 4 extended to form a paper-apron 5. The apron 5 is provided with cut-out openings or notches 6, forming tongues or fingers 7, between which, in the openings 6, front pressure-rolls 8 may be shifted into and out of engagement with the platen. Similar openings are provided at the rear of the paperapron for rear pressure-rolls 9. In the particular machine shown in the drawings, the

openings for the rear pressure-rolls 9 are tendency to foul and obstruct the frontinsertion of a work-sheet.

To facilitate inserting the work-sheets at the front of the platen, there is provided a shield 10, overlying the usual paper-apron 5 and terminating at its forward end in an out-turned marginal part forming a fold 11. The shield 10, which is of flexible material such as strong paper, or other suitable sheet material, may be inserted from the rear and advanced around the platen until the fold 11 has moved beyond the edge of the main apron 5. The shield 10 is now moved in the opposite direction until the front fold .11 thereon engages and covers the forward edge of the main apron 5. The fold 11 forms an uninterrupted smooth rounded edge, to enable a work-sheet to be inserted downwardly at the front of the platen, between the platen and the shield 10, for the typing of a single line upon the work-sheet. Also it is to be noted that the shield 10 forms an uninterrupted smooth sheet-guiding surface over the roll-openings 6 in the main paper-apron 5, thus rendering it impossible for the bottom edge of a worksheet to catch against the edges formed by the openings 6 should the work-sheet be pushed rearwardly beyond these openings. The rear end 12 of the shield 10 is detachably clamped on the paper-table 4 by spring clips 13 fixed on the paper-table. The feedrolls 8 and 9 may be cast off by a lever 14:.

The operation is as follows: The shield 10 having been installed upon the machine, as described above, and the feed-rolls remaining cast off, a bill-sheet 15 is inserted from the front of the machine. This is readily accomplished since the shield 10, where it is bent to form the fold 11, presents a smooth rounded uninterrupted upper edge spaced from the platen. The bill-sheet is adjusted, in the usual way, to the line upon which the items are to be typed. To avoid displacement of the work-sheet during the typing, it may be temporarily clamped in position by throwing on "the feed-rolls or paper-holders. When the single line has been typed, the feed-rolls or paper-holders are thrown off, the bill-sheet removed, and a new bill-sheet inserted in the manner described.

When the shield 10 has been installed upon the machine, it forms a permanent part or feature thereof and remains in its fixed position thereon, while successive billsheets may be inserted, each to have a single line typed thereon, and then be withdrawn. Obviously, the shield 10 may be removed or detached from the machine to adapt the machine for writing upon ordinary work sheets inserted from the rear and fed around the platen, and line-spaced in the usual way, by means of the rolls 8 and 9, which then become feed-rolls. According to the present invention, the pressure-rolls 8 and 9 are used only as clamping means to press the yieldable shield 10 upwardly to cause the latter to clamp the bill-sheet 15 against the platen while a single line is typed thereon.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Iaving this described my invention, I claim:

1. In a typewriting machine, the combi nation with a cylindrical platen, feed-rolls to engage the bottom thereof, feed-roll castoif means, and a paper-apron extending around the bottom of the platen to the delivery side thereof and provided with feedroll-accommodating openings having edges on which the bottom edge of a work-sheet thrust downwardly at the front of the platen, when the feed-rolls are cast off, is liable to catch, of means for preventing such catching and for thereby converting said machine for front-insertion, comprising a shield sufficiently flexible to be readily insertable from the rear between the platen and said paper-apron, and means to secure said shield on said paper-apron over said openings and with its forward edge covering the forward edge of the paper-apron.

2. In a typewriting machine, the combination with a cylindrical platen and a paperapron extending around the bottom of the platen to the delivery side thereof and provided with feed-roll-accommodating openings extending to the front edge and form ing fingers therebetween, thereby rendering it liable for the bottom edge of a work-sheet, thrust downwardly at the delivery side of the platen, to catch on said fingers, of means for converting the machine for front-insertion and thereby preventing such catching, comprising a shield readily insertable from the rear between said platen and paperapron to cover said openings, and having an outwardly-turned fold at its forward edge to be drawn rearwardly over the forward ends of said fingers to form a smooth forward edge, and means to engage the rear end of said shield and detain it in fixed position relative to the paper-apron.

In a typewritingv machine, a revoluble platen, feed-rolls to run on the bottom of the platen, feed-roll cast-off means, and a rear paper-table extending around the bottom of the platen to the delivery side thereof and comprising fingers at its forward edge with feed-roll-accommodating openings therebetween, thereby rendering it liable for the bottom edge of a work-sheet, thrust downwardly at the front of the platen, to catch on the papertable, and means for converting the machine for frontinsertion, when the feed-rolls are cast-off, of work-sheets without such catching, com prising a shield having a fold at its forward edge and readily insertable between the rear paper-table and the platen to advance said fold beyond the ends of said fingers, and forwardly-extending clips on said pa per-table to receive and detain the rear edge of said shield when the shield is drawn rearwardly to place said fold over the forward ends of said fingers to form a smooth forward edge, said feed-rolls being rendered effective, when desired, to press'said shield towards the platen to hold the work-sheet during typing thereon. I

4. In a typewriting machine, a cylindrical platen, a rear paper-table associated therewith, a smooth front-insertion shield to be placed on said paper-table, and clips at the rear edge of said paper-table to press the rear edge of the shield against the papertable and thereby detain it in fixed position.
