Cl. 156-519 6 Claims ABSTRACT OF THE DISCLOSURE Apparatus for correcting photocomposition or cold copy is described which includes a portable outer frame, transversely mounted inner rollers, a non-sticking ramp, a copy edge guide, a beam splitter, and reflecting reference lines, such apparatus is capable of being positioned over errors in a line of type to be corrected with the base line of the type and a reference line in optical alignment. A self adhering strip with corrections thereon can then be aligned over the locations at Which errors occur and With the base line of the correction in proper alignment, the strip can then be cut and the severed portions with corrections applied in covering relation to the location at which the errors occur.

BACKGROUND OF THE INVENTION Field of the invention This invention relates to apparatus for correcting photocomposition or cold copy by which self adhering strips with corrections thereon can be applied thereto which strip is aligned, cut and the cut strip portion with corrections thereon pressed down over the errors.

Description of the prior art In the printing industry there has been a large recent growth in the use of phototypesetters for obtaining copy to be used in photographically oriented printing processes. The principal interest in connection with this invention is in the use of paper output rather than with film or transparency output which-may also be produced by phototypesetting operations. The paper copy is pasted down into page units and then usually rephotographed. The presently available methods of and apparatus for correcting errors in the printed copy are laborious, inaccurate and slow.

One common method now employed involves superposing a strip with correction line over the error while the copy is held on a light table. The Word or line is cut through both layers and the incorrect portion is then discarded. The correction is then pressed into the window obtained by the cutting and held therein by pressure sensitive tape on the back thereof. One other method involves the use of strips with precut lines which are aligned over the error on a light table and then pasted down.

The results obtained were unsatisfactory in that the copy was messy, of poor visibility, and with incorrect alignment.

SUMMARY OF THE INVENTION Apparatus for correcting photocomposition or cold copy wherein portions of self adhering correction strips can have the type base lines thereof aligned with the type base lines of the erroneous text. Portions of the correction copy are then cut and forced down to cover the errors thereby providing copy that has the corrections properly aligned and of good visibility.

The principal object of the present invention is to provide apparatus for correcting photocomposition or cold 3,573,138 Patented Mar. 30, 1971 copy wherein the base lines of the type of the error and of the correction strip are aligned, so that a portion of the correction strip can then be cut with a sharp instrument and the correction strips pressed down onto the error.

A further object of the present invention is to provide apparatus for correcting photocomposition or cold copy which facilitates providing an accurate clean corrected copy.

A further object of the present invention is to provide apparatus for correcting photocomposition or cold copy that is simple and easy to operate.

A further object of the resent invention is to provide apparatus for correcting photocomposition or cold copy that is sturdy and reliable in operation.

Other objects and advantageous features of the invention will be apparent from the description and claims.

It should, of course, be understood that the description and drawings herein are illustrative merely, and that various modifications and changes can be made in the structure disclosed Without departing from the spirit of the invention.

Like numerals refer to like parts throughout the several views.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now more particularly to the. drawings the apparatus for correcting photocomposition or cold copy is illustated as having an outer frame with vertical side panels 10 and 11, joined together at the rear thereof by a forwardly and downwardly inclined hand hold bar 12, which is held in assembled relation by a plurality of screws 14 engaged therewith and with the panels 10 and 11.

Above the bar 12 each of the panels 10 and '11 is provided with a cut out portion 15 to facilitate a comfortable positioning of the hand.

At the top rear of panels 10 and 11 a bar 16 is provided with its ends set into a vertical groove 17 in each of the panels.

The bar 16 has a horizontal panel 18 movable in grooves 19 in panels 10 and 11 and being adjustably movable vertically upwardly and downwardly by adjustment of thumbscrews 20 in the panels 10 and 11. A plurality of vertical reference or cursor lines 21 are provided on the panel 18. A horizontal base reference line 22 is also povided on panel 18 whose position may be varied, depending on the size of type to be corrected, by adjustment of the thumbscrews 20.

Below the hand hold bar 12 two rotatable advance rollers 25 are provided extending transversely and secured to the panels 10 and 11. The rollers 25 are of the nonstick type and can be Teflon coated or knurled as desired. An additional supporting roller 26 also extends transversely below the rollers 25 to permit of more easily positioning the apparatus at the desired location for use.

Between the panels and 11 at the front thereof a stiffener plate 27 is provided, the plate 27 being composed of any suitable material and secured to panels 10 and 11 by screws 28.

Below the plate 27 the panels 10 and 11 each has a triangular shaped portion 30 and 31 extending forwardly therefrom attached thereto and mounting a triangular non-stick ramp 33 therebetween, with a front edge 33a. The ramp 33 is preferably composed of a porous metal impregnated with a silicone of well known type, however the ramp may be coated with Teflon or other suitable non-stick material as desired.

A transparent edge guide 35 is provided extending over the ramp 33 and raised a sufficient distance from the ramp to provide a clearance therebetween. The guide 35 may be held to the portions 30 and 31 by screws 36. The guide 35 is preferably composed of clear acrylic plastic, such as Plexiglas as made by Rohm and Haas Company, and has a front gaging edge 35a somewhat in front of edge 33a, and extends beyond the panel 11 to form a leg 37. This leg 37 and the indicated protrusion serve as a stop for the preferred cutter used with this invention. A particularly suitable cutter is shown in my prior application filed Aug. 8, 1967, Ser. No. 659,077, now Pat. No. 3,448,519.

Directly above the plate 27, semi-triangular shaped panels 42 and 43 are provided integral with panels 10 and 11 extending forwardly which have angularly rearwardly and downwardly incline grooves 45 therein. The grooves 45 retain a beam splitter 51) therein which is so angularly an linearly related to the reference lines 22 of panel 18 and the baseline of the type line 51 on the paper strips or columns .52 that their position is shown simultaneously and superimposed for correction operations.

Rearwardly of the front roller 25 an additional connecting member 53 is secured to and between the panels 10 and 11 by screws 23. The member 53 is provided with a transverse slot 54 which contains an adjustable strip edge guide screw 55 for retaining the correction strip 56 in proper position, the opposite edge of the strip 56 engaging the inner face 57 of the wall 11.

The mode of operation will now be pointed out.

Strips 56 with correction lines thereon corresponding to errors in a column of paper copy are prepared. The proper size margins are trimmed on this strip 56 and this strip 56 is then coated on the back side 'with a suitable pressure sensitive adhesive or wax. The strip 56 is then prepared for use by threading it over the rollers 25 and between the ramp 33 and edge guide 35. Initially this strip is not allowed to extend beyond the edge 35a. The entire unit is positioned so that the image of 22 as seen in the beam splitter 50 falls on the base line of the incorrect line on column 52, and the left and right hand margins of the correction and incorrect lines are aligned. After this positioning operation, the strip 56 is pushed forward with the fingers pressing on the strip over roller 25. The strip 56 is pushed forward until the correction line aligns with its baseline on the image of the reference line 22. A cutter is then used to sever the line from the strip 56. The preferred cutter to use is one holding a blade and having a reference foot to control the depth of cut as shown in my prior patent application referred to above. This cutter is passed against the guide edge 35a to simultaneously cut off and burnish down the correction line in the proper position.

The adjustment screws 20 are previously positioned so 4 that the reference line image of 22 is sufficiently in front of 35a so that the cut falls below the dcscenders of the type.

The apparatus is then moved along the remainder of the column 52 and other corrections are cut and pressed down as needed. The operations are repeated until all the errors have been corrected. The apparatus can be provided with a new strip of corrections 56 and additional columns 52 corrected as required.

It will thus be seen that apparatus has been provided with which the objects of the invention are attained.
