To all whom z'v' may concern:

Be it known thati, EDWARD' B. Hess, 'a

YI have shown paper or card holders cooperating. with the platen and extending up in front of it'across the line of print. These 'holders are arranged'n both sides of the printingr point and are carried in the ends of standards or paper guiding arms mounted below the platen on the main frame or on the carriage shift rail.v They are, therefore, stationary with respect to the transverse traverse ot' the platen.` They are normolly permanently attachedA to the machine but are detaehably secured so that they are.

capable of removal and replacement when specially desired.- The .prima-ry purpose of that invention is to hold cards orsti sheets close against the platen at and above the printing line so as to insure goed. impressions of the types.

The present invention comprises an improvement upon the organization disclosed.'

in said patent and consists in mounting the card holders, or either of them, so that they may be swung on a pivot-from in front of .the line of print to expose it to unobstructed view. The holders should prefer- 'ably be permanently attached to their support orstandards in such way that they may be swung down from infront of the printing line to expose it to view. Thus the holders may be, and preferably are, hinged so that they may befswung laterally downward out of the Way. "With reference to the support carrying the holders it should be said that it may assume a variety of forms. As herein shown it is a plate screwed to the shift rail and formed in` its upper part with two arms' or bifurcations that constitute standards, one on each side'of the printing point.' Sometimes it is desirable to employ with card holders a printing line scale and so in the present case I have shown one attached to'or forming part of the two arms or standards. Its scale edge lies closely adjacent or at the base of a line being printed. When writing upon ordinary sheets and the card holders are not requisite or desired v they may 'be swung out of the way and so remain' until' .the operator again requires them. The card holders may be in the form of rollers Whose axes are transverse to that of the platen, or they may be made of dat lmetal 'fashioned into-concavo-convex form, the convex 'faces curved in the direction of the length `of the platen, extending across the line of print and eoperating with the surface of the platen. in either case the holders are preferably made to conform in vertical lines more or less4 closely tothe curvature of the platen; and in either case, theireurvature-serves to direct the edge of cards or paper under there in the lateral movement of the carriage in either direction. ln the accompanying drawings: Figure l is a front elevation showing so much of the apparatus as is deemed necessary to illustrate the invention. Figs. 2 andB are detail views on an enlarged scale showing the mannerin which the hinged roller paper holders may beswung from in front ot' the printing adapted to be entirely removed from its support: Fig. 9, a front elevation showing /roller holders, the left hand one of which is capable of removal from its supporting,r arm.

Fig. 10 is aview'sirnilar to Fig. 9 showing.

round roller-like holders not, however,

adapted to, rotate but capable of being entirely rehoved from theirsupporting arms.

The drawings may be taken as an illustraloof' tion of, the application of this invention to the Royal Standard machine.

a indicates the ordinary transversely movable rotatable platen broken away at both ends. All parts of the carriage andthe paper feed devices are omitted except that the shift rail c and front feed rolls b are indicated in Fig. 1.

d is an ordinary type har guide of common' construction to be `secured as usual tothe ies ' segment in which the type bars are pivoted;

and e an ordinary ribbon vibrator movable up and down and guided on the standard of in front of the platen in close proximity thereto.` They may serve to assist in directing the paper upwardly to the printing line.

' As shown, `the scale z' is attached to the rear facesof 'these arms or standards g, It, by screw bolts 11. The scale lies suitably adjacent the-face of the platen and its upper edge vis closely adjacent or at the line ot' prlnt. Opposite the type bar guide, behind which it lies, 'it-has anotch to permit the types to print through the ordinary ribbon upon the paper or card on the platen. The tops ofthe arms g, h, terminate at or below the line of print and have4 permanently hingedto them card holders in the form of rollers g', It. These rollers taper inwardly from theirv upper ends downwardly in curved lines so that they approximately conform to the curvature of the platen, and, as in my before mentioned patent,.

are out of Contact with,v the surface of the platen, as seen in Fig. 2. lThey are attached to their standards by hinge joints j, .whose axes are parallel with the axis of the pla-ten. They may therefore be swung to the 'front or toward the o erator into the position shown invFig. 8. en elevated to working position, the block g?, into which screws the pin that forms thebearing for.' the roller,

presses' against the upper edge of the scale 'Y plate pressing it rearwardly as will be seen ist m Fig. 2.. The scale plate being of spring lmetal or'being resilientserves as a retaining spring that bears upon' the flat face of the 'block g2 to hold the roller in operative position. The scale plate and arms g, 4l1., are

preferably all resilient. The block g2 has a projection g3 from its front edgeand when the roller is thrown forward as in Fig. 3, the' projection comes against thearm g and supports the roller in horizontal position. Both roller clamps are mounted in their -respective K arms inthe-same way.

Reir'eirring to Fig. 4, it vwill be 'seen that it shows substantially the same arrangement. The type bar guide and ribbon vibrator are, however, omitted. The cardholders in this figure are shown as sheet metal trowel-like parts extending acrossfthe line of print,

theirsmall or pointed ends being uppermost.

,'Ilheyare concavo-Convex as seen in Fig.- 5, athe convex side, curved 1n the d1rect1on'of the length of .the platen, being contiguous to andfut of contact with the platen' and il'heilg 'also curved in the direction o the circumference of the platen. These holders may, as seen in Figli, be hinged to the upper ends of the arms or standards g, z., in the same manner as are the rollers shown in Figs. 2 and 3. For some reasons, however, I prefer that, of whatever form they may be, they shall swing laterally. A convenient way in which this may be eiiiected is shown in Figs. 4, 6 and 7 which illustrate the trowel shaped paper holders. The outer edges of the'arms or standards h, g at their upper portions have enlarged' or lateral extensions g", it, These extensions are disposed in a plane oblique to the axis of the platen andhave formed in their front faces two circular depressions m, o. These depressions are in a line oblique to the scale and a` prolongation of which would extend obliquely across the front face of the platenv intersecting the circumferential line in which -the printing point is located. The holders are formed with obliquely. disposed extensions ic which are pivoted intermediate the two circular depressions to the standard h, g, by Vpivots or screw bolts k2. /The two circular Vdepressions m', o are the same distance from the axis ofthe pivot and in the' end ofthe extensions Ic', .at the same distance from'the axis of the pivot [c2 as the the depressions m, 0 there is a depression made in the metal forming a concavo-convex protuberance in the under sidel thereof.

Since both the parts 7c and their support-` ing standards are more or less elastic, the vholders may be swung laterally and will be held frictionally either in elevated position, 'as indi-catedl at the right hand side of Fig. 4, or in depressed condition, :1s-indicated at the left hand side of that ligure and in Fig. 7.

In Fig. 9, the standard It has immovably connected with it a roller paper 'holder whereas the` standard g shows :a rollerwith a spindle @that is removably seated in for- 'wardly projecting flanges s', s2 onthe stand- 4' 4llt), paper holders of stillianother coiis'trueton are removably carried by each.

of the arms g, it. Each of these holders is f made'as follows: The upper part t is cylin- "drical and at a point above the upper edges of thermale z it is tapered inwardly as at t.

The "iwer end of the tapered part has secured toit a rather heavy eoiled'spring t2.

'The lowerand of the spring isconnected to .ai spimdlejtand the spindle is removably 13o 1ro this form of. the device vthepaper holders 'may be lifted bodily from engagement with l seated in lips -or' iianges u, u projecting from the. front tace of the standard. A. paper holder of this kind is in itself yielding or elastic and when mounted as shown and described may be removed bodily from in front of the printing line.

ln all forms of paper holders that have i been described, the surface thereof, coperating with the platen, flares or is curved outwardly at each side so that the edge of a" card or sheet will readily be directed between the holder and the platen.

The paper holders or fingers are so shaped as to conform more or less circumferentially to the platen and since when in operative position they lie closely adjacent, or against,

i -the surface of the platen thev should, if

moved laterallyv from in front df the line of print, swing in aplane oblique to the axis "tot the platen in order to properly clear the same. This is clearly shown in Figs.' 4, 6 and 7 I claim:
