To alt whom tmoyoancer'n:

Be it known that I, CHARLES SrrnoQcitizen of the United States, residing at New York, in the county of New York. and State 5 of New York, have invented certain new and useful Improvements in Paper-Tables, of which, the following is a specification This invention relates to a paper table and particularly to a construction adapted for application to the platen of a type-writing machine and comprises a division of my application for patent of the -United States of America filed January 13, 1919, and hearing Serial Number 270,912.

The inventionhasfor an object to pro vide-a novel and improved construction'of paper table carrying a. feed roller dlSPOSBLl to oontaotwith the periphery of the platen u on the under .face thereof in a vertical.

p ane substantially coincident with the axis of the laten.

vAnotili vide'an improved construction of plvoted papertablc extended beneath a platen and carrying a feed roller mounted ina frame pivoted upon the table at an angletothe 'pivot thereof. 'c

A -furtherobjecto f the invention is to present a new structure of curved paper o table pivoted above the axis of a ooiiperating.

platen and formed with. a hand hold-above said pivot and a longitudinally extendin slot in its portion beneaththe platen having :1 depending wall=upon which. a roller carrying frame is pivoted at ananglezto the pivot of the table.

' Gther and further objeots and advantages.

t .for-th of the invention will be hereinafter ed by and tllQJlOVB'l features thereof d the appendedclaims.

Inthe dravyin l igure 1 is" a rout elevation. showing the invention applied to a. typewriter platen;

Fig. 2 is a vertical section on'lin'e.

frame which may be'of anfy desire con-- struction' or configuration; instance as heremshown, COIllPl'lSlhglillB oppos te end oi object of the invention is to proflange central risersll connected at, the rear by the bar 12 and at their. frontby the bar 131 Each of these risers 'is provided with a curved bearing socket 14 adapted to receive the shaft 16 of the typewriter platen. 17. This '60 platen maybe mounted. in any desired mannor, but preferably for removal as disclosed in my application filed January 13, 1919, Serial No. 270,912.

The paper table 30 is provided with lugs. B5 18 pivotally mounted upon a bearing rod 31' carried by the'platen frame, and its upper end32 above this pivot is extended vertically and rearwardly to provide a hand hold for rocking the table 3011 its pivot. The forword portion 33 oi the table extends boneuth the axis of the platen 17 and to the front face thereof. The portion of the table from its pivot to a vertical plane through the .axis of the platen is spaced from" the periphery of the latter to provide a down-' wardly tapering insertion space to receive the sheets of paper and compress and guide them into proper relation to the periphery, oftheplaten.- i

The forw'ard portion of the table is pro- ."vided at substantially its midlength with an elongated slot 3-1 having a do ending flange 35 at the inner wallfthoreoii This flange may be conveniently formed by bend- 3 ing the material out to form said slot. Upon this flange the bearing roller 36 is mounted with its shaft 37 supported by the an is frame 38 which is plvoted at 40 upon t e;

of its length. to oscillate. in a, vertical p one; The axis of this roller wheiiin contact with the platen lies insuhstantiallythe same vertical lane-as the platen axisand directly beneat said axis.

he table is firmly held in contact with the platen by a'ny desired means, for instance a, spring 41 mountgd to surround the hear ing 31 and bear against the table and the rear bar 12; assho'wn in Fig.'2. i

The operation of the invention will be apparent from the foregoing description and it will be seen that the disposition of the table relative to the periphery of the laten provides an extended tapering space or the introduction of the" paper at the rear and into contact with the feed roller disposed boncath the platen axis.- When a number of sheetsof paper are used, such as for carbon copies. this tapering space com tosses the some and brmgs them into straig t conthe table which forces it into contact with v the periphery of the platen. This antomatic leveling of the roller into parallelism with the platen provides the most efficient means for feeding a single sheet, or a pluralit y of sheets, in straight position from a point beneath the platen axis u ward into the line of printing. The are 0 travel of the roller toward the table applies the pres sure upon the platen upwardly and forward of its axis which assists in preventing vihration of the platen at the printing stroke, and is also particularly adapted for use with a'reniovable platen. on it is desired to relieve the feed roller contact to adjust or remove the paper the upper end of the table may be drawn forward by the hand hold thus causing the roller to be withdrawn from the surface of the platen,-a's indicated by dotted lines in Fig. 2. This construction also permits the admission and straight feeding of paper folded at one side, or short onvelops, as the roller adjusts itself to such inequalities in thickness.

It will be seen that this invention presents a verv' simple, cfllcient and economically manufactured construction adapted .to secureimproved results in a paper feed mesh anisln. While many of the details of'the structure have been specifically described,

still the invention is not crmfincd thereto as changes and alterations may be made within the scope of the following claims.

What I claim is I 1. In a typewriter, a platen frame provided with risers, a platen having a shaft mounted therein, and a paper table pivoted upon the frame at the rear of the platen above 25 its axis and provided with a bearing roller disposed to contact with the under'face, of laten in substantially the vertical plane oft e axis thereof.

2. In a typewriter, a. platen frame, a platen pivoted therein, a paper table pivoted at the rear of the frame, and a feed IOller having a frame pivoted upon said table at an angleto the pivot thereof and disposed beneath the body of the platen.

3. In a typewriter, a platen frame, a platen pivoted therein, a paper table pivoted at the rear ofsaid frame and extending beneath said platen, and a feed roller having a frame p voted upon said ,tahle'at an an le tothe pivot thereof and disposed housed! the platen axis in a vertical plane extending therethrough.

4. In a, typeyrriter, a piston frame, a
