TYPE-WRETING MAGHINE.

' Patented April 16, 1907.

To all whom it may concern:

Be it ,known that I, HARRY S. MCCOR- MACK, a citizen of the United States, residing in New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification. This invention relates to the paper-carry ing devices of type-writing machines, and particularly to those in which it is desired to retain one sheet in the machine while another sheet is removed and a third one introduced.

Usually the retained sheet is intended to re ceive a carbon record of all the entries made The record-sheet'is usually very long, while the others are short. The long record-sheet usually hangs over the back of the machine, together with the usual long carbon-sheet, and are found to be in the way during the introduction of the small per-shelf 6, inclining upwardly and rear sheets at the rear of the machine. In order to overcome this difiiculty, I provide a device for throwing the long sheets forwardly over the top of the platen, thus leaving the rear of the machine clear for the convenient introduction of the next short sheet. Said device is in the form of a flap, and preferably is just in front of the usual rear paper-shell, whereby the flap serves also as a shelf for supporting the long sheets. The flap is preferably in the form of a light zigzag wire frame, but heavy enough to hold down the sheets over the platen.

in the accompanying drawings, Figure 1 is a front elevation, partly in section, of the platen and platen-frame of an Underwooc front-strike writing-machine with my in provenients applied thereto. Fig. 2 is a sectional elevation of the same, showing the long record-sheet and short bill-sheet in posi tion for writing. Fig. 3" shows the long record-sheet thrown forwardly and held down out of the way by the flap during the introduction'of another short bill-sheet. Fig. 4 is a plan illustrating one joint of the flap-hinge;

Types 1 strike rearwardly upon the front side of a, platen 2, having an axle 3, whereby it is mounted in the ends 4 5 of a platen frame-the latter also including the usual pawardlyironi the platen-and at its forward portion curving around under the platen, as

- usual. Releasable rolls 7 press against the under side of the platen, and front paperguides 8 slide along a rod 9, as usual, so that the paper is guided and fed around the platen in the usual manner.

The long record-sheet 10 is passed around the platen, Fig. 2, and rests upon a flap 11 in the form of a wire frame, the wire being bent end portions in a pair of cars 12, projecting up from the platen-frame ends. are just in front of the paper-shelf 6, and the frame 11 extends upwardly and rearwardly from its hinge-joints and is provided outside of said ears with short arms 13, which rest'at 14 upon the rear edges of horizontal portions 12 of the ears, said edges forming stops to prevent the flap from falling back farther. A short or bill sheet 15, Fig. 2, is seen passed around-the platen in position to be written carbon is placed between said sheets 10 and 15.

When the bill 15 is-completed', the'pres sure rolls 7 are released and the bill withdrawn. Then usually the platen is turned back to receive a new sheet. At; this juncture the flap 11 is swungforward'and down, Fig. 3, thereby throwing forward the sheet chine, the weight of the flap holding said duction of a fresh bill-sheet 15 at therear of the platen, said sheet passing in between the l paper-shelf and the flap. After the sheet 15 18 introduced the pressure-roll 7 is brought into action to hold the sheets, and the flap 11 is thrown back. to the Fig. 2 position, together as before. light, but at the same time of sufficient weight to beheld by gravity in both positions at Figs. 2 and 3. v

I Variations maybe resorted to within the scope of myinyention.

Having thus described my invention, I claim.

' i. In a type-Writing machine having a platen and papenfeeding devices, the combination with a main p'aper-shelfin rear of the platen, of an auxiliary paper-shelf in the form oi a flap between the pa air-shelf and platen and entending upwardly and rearwardly movable forwardly and downwardly to hold long record-sheets down out of the Way,
