COPYHO DING DEVICE Laura Givens Berry, Tucson, Ariz. (Room 2219 Central YMcA, 1421 Arch St., Philadelphia 2, Pa.) Filed Dec. 19, 1958, Ser. No. 781,700

' 1 Claim. (Cl. 120-32 The present invention relates to a copyholding form of the type, which is useful for typists and typesetters in holding and manipulating copy.

A purpose of the invention is to support the copy in a more convenient position for the operator.

A further purposeis'to avoid, the necessity for the op erator to look up or down in following the copy.

A fnrtherpurpose is to reduce the space occupied by the copy when it is being followed by the typist or other operator.

A further purpose is to facilitate reading of interlined material on copy. i

A further purpose is to magnify the line of copy under observation. 7 p

A further purpose is to advance the copy by rolling on one roller and unrolling from another roller of ,two ad-' jacent parallel rollers. i

A further purpose is to feed the copy behind a suitably ransparent guide bar desirably having a lens-like s u'race.

A further purpose is to make the device readily trans portable.

1Further purposes appear in the specification and in the In the drawings I hav chosen to illustrate a few only of the numerous embodiments in which my invention mayappear, selecting the form shown from the standpoints. of convenience in illustration, satisfactory operation and clear demonstration of the principles involved.

Describing in illustration but not in limitation and referring to the drawings:

The conventional practice in mounting or handling copy to be used by a typist or a typesetter is either to place the copy on a vertical frame which is relatively above the eye, or to place the copy on the desk or other support to one side. In either case the head is turned into an uncomfortable position, and the operator is not able to look forward in a normal comfortable position.

Some of the devices which have been widely used to support copy have the further disadvantage that interlined material is likely to be obscured by the guide and may not be observed while the line is being copied. This "ice 2 is particularly true if the material is inter-lned below the line.

The present invention is designed to produce a copyholder for use by typists, typesetters and others, which will be conveniently positioned directly in front of the eyes in a normal position, will occupy a minimum'of space, and will be convenient and easy to use and to transport from one place of use to another.

The device of the invention employs two rolls, one of which winds the copy sheet and the other of which unwinds the copy sheet.

The paper is conveniently carried over a paper support" and the eye is guided. In one form, this guiding involves a transparent magnifying device which shows one line considerably enlarged.

Considering now the drawings in detail, I illustrate a copyholder consisting of a U-shaped frame 20 suitably of sheet metal having a back bar 21, and transverse out-.

wardly extending end portions 22. Rollers 25 and 26, in spaced parallel relation to each other, are journaled in suitable holes in end portions 22, being held with sufficient friction in the holes to stay in place unless specifically moved. They can be moved by using handles 27 mounted on the ends of the rollers, or by striking tabs 28. These tabs are on one end of levers 29 fulcrumed' at 30 on the frame, with stop 31 limiting (by contact with the levers) the movement of the tab in the downward direction and spring 32 bringing the tab back to its nor-j mal position after being depressed. Pivoted to the other end of the lever from the tab is ratchet keeper 33 held against ratchet 34 on roller 25 by spring 35 extending from it to the roller.

The ratchet can be so constructed that movement from: one tooth edge to the next corresponds, as far as roller travel is concerned, to the distance between one line and the next in typewriter single spacingand if desired 'an' arrangement similar in principle to that employed in type writer spacing can be used to enable it to advance two or'th'ree such spaces at a time when so set, or if desired the distance between ratchet teeth can be made to con form to such double or triple spacing in the first place.. Each roller has a slit extending well in to theinterior to hold one end of the paper which is being copied on the typewriter.

The paper is desirably spirally wound on both rollers v and is wound up on one roller and unwound from the other roller byturning the roller which is to windthe paper (which may be either the upper or lower roller, as preferred, but in the particular form shown, with its tab cooperating with the upper roller, would normally. be

7 the upper roller). On one roller the ,paper is rolled clockwise and on the other counterlockwise. The stretch of paper extending between the rollers is shown at 41, and the spiral wound portions of paper on the rollers are shown at 42.

The paper between the rollers is desirably carried forward over a paper support 43 which is secured at the end in the flanges 22.

Transverse end portions 22 of the frame include, at the ends toward the user, finger members 44. In between the finger members and the rest of the end portions are straight slots 45, adapted to hold the ends of guide bar 46, which bar is preferably of transparent plastic, preferably acrylic. The guide bar 46 is preferably made up of two parts, an upper part of colorless plastic, and a lower part 48 of plastic colored green, amber or possibly some other noticeable but preferably soothing color.

The lower part 48 will be flat, and will extend over far enough at both ends to rest in slots 45 in the frame. The upper part will be secured to it, as for example by cementing, and may if desired be a longitudinally ex- Patented Oct. 10, 1961 tending magnifying lens, as in the case of upper part 49 in the forms of FIGURES 1-5 and FIGURES 6-7, which shows an enlarged image of ,the line which is being read by the vuser, or it may be instead flat, as .in the case of upper part 49 in the form of FIGURE 8.

With this arrangement, the paper can be so positioned that the .line where the colored andcolorless plastic meet isimmediately below the line that is being copied, serving as an excellent guide for the eye, yet visibility through the colored plastic below will warn the operator when there is material below that line which should be inserted init. Thus a fertile source of errors is eliminated.

The guide bar 46 is readily removable to permit more extensive inspection of the copy, and such removal will desirablytake. place where there is a considerable amount of interliningor interwriting. The guide bar will alsobe removed .to thread in the paper.

The form of FIGURES 1-5 has mounted on the back of the frame two hook shaped members 51 of appropriate size, shape and position to hold the device on the typewriter by extending over the top front of the typewriter into the central well which is present in a great .many typewriters. It is preferably resilient and flexible to atford a clamping action, but may if desired be rigidand carefully matched in size to fit the typewriter. Inthe case where it is flexible, it may if desired be sufficiently so to permit'it to be bppt enough to conform to theparticular typewriter.

The form of FIGURES 6 and 7 has two button-like metal projections '52 fixed to the back of its frame. In this case in corresponding positions in the front .wall of the .typewriter proper there will be put two keyholeshaped holes 53, so that the .head 54 of the projections 52 can be inserted throughthe wide upper part 55 of the hole and the device with a slight downward movement will be firmly held with the shanks 56 of .the projections 52-resting .in the narrow lower portions 57 of the holes.

The .embodimentof FIGURE 8employs rubber suctionzcups 60 rivetedorbolted at 61 to the back barand engaging the from case of the typewriter at '62 in aslightly rearwardly and upwardly inclined position.

Thus thedevice can readilybe detached from one typewriterand used on another typewriter.

In operation, with the guide bars preferably temporarilyremoved, the endsof the paper are inserted into the slits :inthe roller and wound-preferably. oppositely on the two rolls as shown.

The winding roll is then .turned to windupthe paper until .the desired starting position is reached. The :.user then :willdesirably place the guide bar in position, and begin with thefirst line, continuing to'wind up the paper by means of theroller or tab, and read successive linesin order.

Ifit becomes necessaryio inspect the copy-more carefully, the-guide bar eanreadily be removed'for this purpose and then put backin theslot 45.

In view of ,my invention anddisclosure variations and modifications to meet individual whimor particular need will doubtlessbecome evident :toothers skilled inthe art, to obtain all orpartof thebenefits of my invention without copying the structure shown, and -I therefore, claim all such insofar as they fall within the reasonable spirit and scope of myclaim. 7

Having thus described my invention, what I claim .as new and desire to secure by Letters Patent is:

In .a copyholder, a U-shaped frame having .arms and said arms having slots and apertures, a pair of adjacent parallelrolls extending between said armsand journaled in said apertures, each of said rolls having a longitudinal paperreceiving slit, meansfor rotating said .rolls, apaper snpportextending between and supported-by ,the armsof said U-shaped frame, a transparent guide located in a plane parallel and adjacent the ,plane of .the paper sup port and mounted between and in said slots of said arms of the U-shaped frame, said guide having means dividing the guide longitudinally into opticallyfdistinguishable portions so that when said guide is held in said slots a;line of information which is tobe'copied from the copyholder is designated by the guide, and said paper support and guide .being located/outside aplaneiangent to the rolls and on the farside. of :said plane oftthe-roll's from'the axes of the rolls topresent a limited portiontofithe paper in position iforcopying.
