and useful Improvements' in Type-Writing Machines, of which the Afollowing is a specili cation.

vThis invention relates to paper-feeding devices of type-writing machines. rlhe object of the invention is to enable sheets, particularly short ones, and cards, en-

velops, and the like Yto be inserted quickly into thev machines and brought instantly and accurately to the proper positionto begin'thev first line of writing thereon and also to eiect ready release of the sheet after Writing. To' these ends I provide means uponthe platen i 'for receiving and gripping the bottom edge of zo the paper, which is inserted backwardly at the gripping means is inthe then rotate theplaten back as `far iront of the revoluble platen. This paperform of a clip which is mounted'directly upon the'platen and is opened automatically to receive the paper" and is closed automatically when the platen is rotated. I also provide a stop for arresting the platen in the proper position for beginning the first line of writing upon the paper. 'Thus' it is necessary only to drop the sheet or card in at the front of the platen and as it can go and then begin the writing. When the writing is finished, the platen is rotated forwardly until arrestedk by suitable means, whereupon the paper is automatically released and may be taken out and a fresh sheet inserted. I j also provide improved means upon the platen-frame for directing `the sheet downwardly into the open clip upon l platen. V

f ln the accompanying drawings, Figure lis a sectional elevation of a front-strike Underwood type #writing machine, showing my improvements applied thereto, Fig. 2 is 5.o platen,

a sectional' perspective view; Fig: 3, a front elevation, and Fig. 4L a plan of the same.

The platen 1 is journaled in. the usual frame, comprisingends 2 and a back plate or paper-shelf 3. Types 4 strike in front of the and `rolls 5 and 53L press the paper against the platen,Y Upon the platen-frame l mount a clip, comprising a long strip 6, fitting the platen and extending longitudinally f platen,

as far asit thereof and liXed upon the top ends of a pair of spring-arms 7. The lower or rear ends of the latter are secured by pins orscrews 8 upon theend portions of the platen outside of the usual pressure-

rolls

5 and 5, sc that the 'latter never run upon said fingers. The latter normally hold the clip rmly against the so that the sheet of paper 9 is firmly held during the rotation thereof. Upon the clip l; provide a series of gage-pins 10, which are received in recesses 11, formed in the platen- Fig. 1 shows the position of the parts when the sheet is inserted, the clip standing open to receive the lower edge of the sheet, which is'guided downwardly between a paper-shelf 12 and a transparent Celluloid shield 13, which together form a directrix or guide for the paper, the plate 13 being secured upon the shelf 12- an l the latterA eX tending upwardly and rearwardly Jrom the front side of the platen and being secured by arms 14 and screws 15 upon the ends 2 of the platen-frame.

The clip or plate 6 is held open to receive the paper bymeans of a pin 16, projecting from an arm 1.7, secured by a screw 1S upon the platen-frame. The end of the plate 6 at its top edge is bent or flared out at 19 to form an incline or cam. During the forward revolution 'of the platen said pin 16 catches behind said bent portion 19 and .cams the clip open, the platen being immediately arrested by a stop 20 which is intercepted by the pin 1 6.

It 1s a simple matter to drop the sheet down between the

guidelates

12 and 13 un-.

til it enters the clip, whic is just beneath the bottom of said plates, until the bottom edge of the sheet rests upon the gage-pins 10, whereupon the platen is rotated baekwardly by a hand-wheel 21 until the paper is in proper position for writing the first line. The platen may b provided with a stopl 22, to be interceptedbythe pin 16 during the backward revolution of the platen at the point Jfor beginning the Writing of said irst line.

The guide plates 1'2 and 13 may reach nearly to the printing-line onthe laten, so thatA the paper sheet 9 is not carrie down tar enough to escape from said guide-plates before t e platen 1s arrested by the stop 22.

ln operation the platen is turned forwardly p "ll go, and then the sheet 9 is dropped into the directrix and down upon the IOO pins ll). i Th1-n the platen is turned back far as it will go, and the first line is written upon the paper. The writing proceeds 1n the usual manner, the platen being advanced,

the bottom edge of the paper; said vclip revoluble with the platen, and having a gage for the bottom edge ofthe paper; and means for causing the clip to release the paper.

2. ln a type-uitingmachine, the combination with a revoluble platen, of aspring` pressed clip mounted upon the platen to receive and gage the bottom edge ofthe paper, said clip revoluble with said platen and means rendered effective by the forward revolution of the platen for opening said clip at a predetermined point in the revolution of the platen.

3. In a type-writinglmachine, the combination with arevoluble platen, of a clip mounted upon the platen to receive the bottom edge of the paper, means rendered effective by the forward revolution of the platen foropening said clip, and means for arrestingthe forward revolution of the platen immedia'tely'upon the clip being opened.

4. ln a type-writing machine, the Combination with a revoluble platen, and a platenframe, of a spring-clip mounted upon the platen to receive the bottom edge of the paper, means rendered effective by the-forward revolution of the platen for opening sai d. clip at a predetermined point in t e revolution of .the platen 5, means for arresting the forward revolution ofthe platen immediately upon the clip being so opened g and means for guiding the paper bottom end foremost clip at such stopping-point.

5. In atype-writing machine, the combination with a -revoluble platen and a platenframe, of a. clip mounted upon the platen to into said receive thebottom edge of the paper, meansV for opening said clip at a predetermined point in the forward revolution of the platen; and

means upon the platen-frame for guiding the paper bottom end forez'nost into said clip; said guiding means comprising a paper-shelf erected upon the platen-frame at the front side of the platen Vand extending upwardly and rearwardly therefrom.

6. ln a type-writingmachine', the combination with a revoluble platen and a platenfranie, of a clip mounted upon the pl.` te: 1. to receive the bottom edge of the paper, .'neans for opening said clipfandmean-s for guiding paper bottom end foremost into said clip; said guiding means comprising a paper-shelf erected upon the platen-frame and extending from the front side of the platen upwardly and rearwardly, and also including a trans- E parent celluloid shield in front of said papershelf and separated therefrom so as to' form a passage for the paper.

7. ln a type-wr1ting machine, the combination with a revoluble platen and a platenframe, of a paper clip mounted upon the platen to receive and gage the bottom edge of the paper, means rendered effective by the forward revolution of the platen for opening said.

lclip, and means mounted upon the platenframe for guiding the paper bottom edge first into said clip.

S. ln a type-writing machine, the combina-l tion with a revoluble platen, and a platenframe, of a clip mounted upon the platen to receive the bottom edge of the paper, and means rendered effective by the forward revolution of the platen for opening said clip at a predetermined point, means forlimiting the forward revolution of the platen as soon as the clip is opened, and means for limiting the forward stroke of the platen.

9. In atype-writing machine, the coinbinaed upon the platen to receive the bottom edge of the paper; said clipcomprising a plate fitted to the platen and extending longitudinally thereof and spring-arms attached at one en'd to the plate and curving around the platen and attached to the latter, and'pressure-rolls bearing upon said platen between said springarms.

- l0. In a type-writing machine, the combination with a revoluble platen of a clip mounted upon the platen to receive the bottom edge of the paper, a series of gage-pins fixed to the clip, the platen having perforations to receive said pins, andmeans for opening the clip.
