INVENTOR CHARLES H. K0EFP ATTORNEYS Patented Feb. 19, 1952 N l r so Es LGE aaasaosa I corgnopnan PAPERUSU'BBBRT Charles H. Koeppel, North Woodbin'y, Conn., as-

signor, by mesne assignments, to Rite Line Corporation, Washington, D. 0., a corporation of Delaware 2 Claims.

The present invention relates to an attachment for a copyholder and is especially adapted for use with copyholders of the type disclosed in Patents No. 1,939,671, No. 2,162,706, and No. 2,273,841.

Through use of copyholders of the type above mentioned, it has been found that, due to the flimsy nature of paper, the copy tends to follow the contour of the copyholder casing in back of the eye guide and then drop behind the copy holder, with the result that the copying thereof is rendered more difficult by the slant at which the print must be read. Another disadvantage stemming from the above is the casting of a shadow on the line being copied by the eye guide, a consequence of the copy not being flush against the eye guide.

It is therefore the principal object of the present invention to provide a paper guide for a copyholder which supports the copy above the copyholder in such a manner as to permit more facile reading thereof and to eliminate shadows.

Another object of the present invention is to provide a paper guide which is laterally extensible to accommodate paper of varying width.

Other objects of the invention will be evident from the following detailed description read in connection with the appended drawings wherein:

Figure 1 is a perspective view of the paper guide of the present invention attached to a copyholder.

Figure 2 is a side elevational view of the same.

Figure 3 is a rear elevational view of the paper guide per se showing in phantom lines the frame in extended position.

Figure 4 is a rear elevational view of the guide flap forming a part of the present invention.

Figure 5 is a rear elevational view of one of the frame sections forming a part of the present invention.

Figure 6 is a fragmentary vertical sectional view taken along the line 66 of Figure 3.

Figure '7 is a vertical sectional-elevational view taken along the line 1-1 of Figure 3.

Figure 8 is a vertical sectional view taken alon the line 8-8 of Figure 4.

Figure 9 is a vertical sectional view taken along the line 9-9 of Figure 5.

Figure 10 is a plan view of the blank from which the sleeve forming a part of the present invention is formed.

Referring now in greater detail to the drawings, in Figures 1 and 2 I have shown the device of the present invention attached to a copyholder which comprises generally a casing l I, a tubular paper retainer l2, paper feed rings IS, a spacer bar l4 and a spring actuated paper presser and eye guide [5. To presser and eye guide I5 is attached the paper guide forming the present invention and embodying a guide flap l6 and an extensible frame ll.

Referring now to Figures 4 and 8, guide flap l6 consists of a single sheet of metal bent to form a channel l8, the purpose of which will be hereinafter more fully described. The rear section 19 of guide flap [6 is struck out at intervals as indicated at 20 to form supports 2|. The front portion 22 of guide flap I6 is considerably longer than the rear, the extended section being curvilinear to complement the contour of similar shaped pressers and eye guides. Adjacent the lower edge of front portion 22 the metal is pressed out to form projections 23 which snap over the upper part of presser and eye guide Hi to hold the paper guide in place.

Extensible frame I! comprises a pair of U- shaped sections 24 (see Figures 5 and 9). These sections of the frame member are placed with the free ends of their longitudinal rods overlapping and the free terminal of each top rail has riveted to it at 25 a sleeve 26 (see Figure 7).

.Each sleeve is preferably formed from the blank shown in Figure 10, and is bent over the overlapping rail to hold the lapped and overlapped portions of the mentioned rails in contiguous relation but permitting relative sliding movement of the sections. Sleeves 26, when abutting, also serve to limit the amount of lateral extension of the frame sections. The lower rail of each frame section 24 is trained in channel l8 of guide flap l6 and rests on supports 2|. To frictionally retain frame I"! in association with guide flap IS, the opposite ends of channel I8 are contracted by having the lower lateral extremities of rear portion I9 of flap I6 pinched as indicated at 21 (see Figures 3 and 6) In use frame ll of the paper guide is longitudinally adjusted to the paper width by manually manipulating frame sections 24 in an obvious manner. The copy is then placed in tubular retainer l2 and passed upwardly between feed rings l3 and presser l5 by operation of spacer bar 14. The back of the copy rests against the top member of the paper guide so that the paper remains in an easily readable condition from the eye guide 15 to the top member of the frame and lies flush against presser and eye guide 15 to eliminate shadows.

Although I have herein shown a preferred form of the invention, I am nevertheless aware that various changes may be made therein within the struck out at interval to form supports for the scope of the claims hereto appended. frames.
