.To alljwhom it may concern:

'of which 'the following is a speciiication. .My invention relates to paper gaging, guiding, and .feeding mechanisms `for type- Wntmg machines.

The object of said invention'is to provide vsimple and efficient means whereby the' paper vmay be readily inserted inthe paperfeed mechanism with assurance that the leading edge of the paper will always-be started from the same point and thatthe lpaper will be properly positioned or s uared therein and without the necessity of epe-nding upon the' eye or judgment of the operator to determine whether the paper is properly posiwherein like Areference characters representVl tioned or Whether it is straight or not;

v To these and other ends, which will. hereinafter appear, my invention consists in the novel arrangement and combination'of parts -to be hereinafter described and claimed.

Referring to the accompanying drawings,

. corresponding parts in the several views,

Figure `1 is a rear view of suflicient numb er of pairtsofa carriage of a type-writing machine toillustratdmy invention, the parts being shown in the `released position indicated in qFig. 2.

Fig. 2 is an end view of the same. Fig. 31s a transverse sectional vlew taken on the line X X ofFig. Il and looking in the direction of the-arrow in said figure, this view,

Fig'. 61 detailend view of the beingshown lin t said frames in co era-tive relation, the parts y e posltions representedl at Fig. 2.v f I in the presen-tginstancelhave illustrated I my inventionconnecti'on with atop-'strike machine of f the '.general character shown' in my Patent No.67f7',110,fdated June 25, 1901, though v,it 4sh'oulClloe.understood', thatpthe iiivention lis innojsense limited to such a may chine, but may be used wherever found available. v The end plates 1 constitute portions of the platen-frame of the carriage in which the platen. 2 is mounted and adapted to revolve. Said end plates, connected by suitable cross bars or rods 3, afford bearings for-various portions of the paper-feed mechanism. A The vpaper-feed mechanism is shown in the present instance' as comprising two springpressed'frames4 and 5, Figs. 4 and 5, which are pivoted tothe end plates, as indicated at 6 and 7, respectively, Figs. 2 and The frame 4 carries a' paper-blade 8, which is pro- 1 yvided on its outer face with -a scale 9, and carried-'by the blade atthe under face thereof is a loosely-mounted paper-feedroller 10, whiehis normally maintainedin contact with the platen, as indicated in the end plates of the framev 4 has an arm that extends to the rear of the pivot 6 of said Figl 3. Each of frame and is notched, as indicated at. 11, for

4cooperation with a pin 12, that is carried by an end plate of the frame 5 and extends inwardly therefrom, vthe pins and notches cooperating to llock the frames 4 and 5 in the positions indicated in Fig. 2, as will hereinafter more clearly appear. Outside of each end plate of. the frame 5 is a link 13, one end of which is pivoted at 7 to the platen-frame,

the other end of the link being pivoted ati17 to the frame 5,- the link 13 thus pivotally connecting the `frame 5 to' the platen-frame.

-The roller and,paper-blade-carrying frame 4 is provided with a nose, cam, or bearing-surface 14, which isadapted to bear against a pa er-blade 15, carried'by the frame 5. It wil be understood that when the frame 4 is moved'from the position indicated in Fig. 3 of theI drawings'to that shown'in Figs. 2 and 6 the. projection or nose 14 will'cause the frame 5 to be moved with it until the arms on the frame 4, which have the notches 11 therein,v are b'rou',1 1;ht into contact with the lpins 12, andsaid'pins spring into notches 11 and arrest further lbackward movement of the frames 4 and 5 `and lock them in the positions shown in Figs. 4 2. and 6.' Springs llare adapted to bear against pivot-pins 17 for the links 13 lwhich pinsin the-present instancel are formed by the ends of theshaft or rod of the paper-feed rollers 18. From an inspec-f.

IOC

tion of Fig. 1 it will be seen that one of these .springs 16 is carried at each end of the platenframe and coperates with its pin 17. While the tendency' of the springs m16 is normally to maintain the frames in the positions indicated in Fig. 3, with the paper-feed rollers in contact with the platen, the frames when 1 regulated by a set-screw 19, and a second projection 21 on each of the side or end spring 2O may be employed to bear upon the plates constituting portions of the frame 4. These springs 2() tend, further, to maintain the parts )in each of the positions indicated in Figs. -2

'and 3 by reason of their coperation withA the flattened portions 22 on each nose 21 when 'the parts are moved to the positions shown. Preferably I provide finger-pieces 23 on the fra'me y4 lin order to facilitate the movement y of the frames 4 'and 5 by hand from the position shownin Fig. 3 to that indicated in Fig. 2, `or vice versa.

The fraine 5 in addition to the feed-rollers 18 is provided with what I term a paper stop or gage 24, which preferably is in the nature of a flat lplate or bar that extends throughout or substantially throughout the length ofy the platen, though it may be notched 'or recessed at various points of its 'length to provide a set of stopsor gages, which project from the bar. parts are inthe positions indicated in Fig. 3 of the drawing, this paper-stop will be maintained in a position where-it affords no obstruction to the free passage of the paper around 'the' platen. When, however, Athe fpa'rts are moved to 'the positions/indicated in Fig. 2, the angle whichthe plane of this stop bears. to thel surface of the platen is changed and the lower edge of the stop is brought. closer to the platen andthe `stop is interposed 'in the path of the leading end or edge'of the paper andcons'ti'tutes-an abutment stop'or gage by means of which 'the y paper can be straightened and properly and evenly fed on the platen, at the same time assuring that thev successive sheets Aintroduced into the machine will always Ibe started fromy a given point, or, Iin other words, that the leading edges of successive sheets introduced into the machine will always be at a given distance from the printing-line and will be squared withrelation thereto. ,This is clearly indicated in Fig. 2

of the drawing, wherein lthe paper 25 has its leading edge or end 26 resting' upon the paper-stop. By having the paper-stop extend throughout the length of the platen paper of various Widths can be efficiently trued or straightened on the stop. After the paper has been inserted in the manner described,

` and a's indicated in Fig. 2, the frame 4 is depressed, thereby relea'sing the notched portions 11 from the pins 12, and the parts will assume the positions shown in Fig. 3 of the drawing. It will be observed that when the parts are in these last-mentioned positions the paperis'rmly clamped upon the platen and the feed-rollers are in cooperative relation to the platen to feed the paper forward therewith. It will likewise be seen that the paper-'sto 24 has been moved beyond` the effective 'aces of the paper-feed mechanism,

' or those faces thereof which contact with the paper, and has been moved to a position where it no longer affords an yobstruction to the free movement of the paper. In' other words, when the parts are in the lpositions shown in Fig. 2the paper-stop 24 is adjacent to the platen, while the feed-rollers and blades are maintained away from the platen, whereas when the parts are in the positionsr shown in Fig-3 the feed-rollers and blades `are in contact with platen and the stop 24 is moved away from 'the platen.; The paperblades 8 and A15 'co 'crate with the paper u on opposite sides o the printing-'lindas is c early indicated in Figs. land 3, so as'l to write on short sheets of paper or cards and so as tornaintain the paper pressed 'against the platen at the `printing-line.

From theforegoing description it will be observed that the feed-rollers are located in advance of the paper stop or gage 24 and that whenever. theV rollers are" moved #a position where ythe paper is adapted tdoibe readily inserted the paper-stop 24-is always effective to'receive or coact with the -leading end or 'edge ofthe paper and to act .as 'an abutment to square it, yand the, vpaper may then be clamped in position4 on the platen .without disturbing 'the' arrangement yof the lpaper attained 'with 'the aid of said stop.

Furthermore, a single movement ofthe alll arts of the. `paperfeeding `mechanism from coperation or contact with the platen, and 'thisfsame movement brings'about `the interposit ion of the paper-stop '24, so 'that lit ywill constitute an abutment for the'proper positioning of the paper.

lIO

Aframe 4 is all that is required to withdraw orpaper-feeding device 18, considered withl v relation to the direction of line-feed of the paper, Vand when the roller is 'forced away:

from the platen the paper may be introduced between the face of the roller and the platen and properly positioned against the paperstop 24. Then when the feeding device 18 is moved into coperative feeding relation to the-platen, as shown in Figf3, the effective face of the roller will clamp-the paper tothe V platen wit-hout disturbing the'arrangement Isp `by Letters Patent, is-

of the paper.

' In f"ldi.'onto the mechanism thusfar described I may provide a paper-shelf` 27, which receives the paper from the platen.

It is obvious, however, that any suitable mechanism may be employed for this purose.

while I have; Shown mi vdescribed .with

considerable detail one form of mechanismembodying my invention, it shouldbe un-v derstood that varibus changes in the structure may be made without departing from the spi.it of my invention and in order to adapt tl.;y invention to various forms of type-Writing machines.
