I COPYHOLDER AND LINE INDICATOR Filed Dec. 8, 1952 a Sheets-Sheet s 6 Tra -1'1 TIE-.11 B 7 V ii. 7 l 1 Z r I} INENTOR W/ZZ/AM ETUfi/Vffi ATTORNEY Patented June 16, 1953 1 My invention relates to new and useful improvements in copy holders and more particularly to the type of copy holder with means at-I tached thereto for indicating lines of typewriting or other written matter, so that the typist may readily read the material line by line and make copies thereof without confusion.

The primaryobject of the invention is to provide a device ofthis character which is provided with a simple and effective means for indicating the lines to be copied and constructed so as to be capable of quick and ready adjustment for varying the line indicator, according to the spacing of the lines on the copy to be reproduced.

A further object of the invention resides' in the provision of a simpleand effective means for locking the line indicating device, so, that lines may be indicate'dcontinuously after the -device is once set for the spacing of the lines.

A further object of the invention resides in the use of a flexible metal tape for supporting the line indicator, aid tape being adapted to be wound on a spring-actuated reel. Still another object of the invention resides in the provision of a register or the like which will indicate the spacing between lines to be indicated and to which the line indicator has been set and locked.

A further object resides in providing a device which is simple and durable in construction, inexpensive to manufacture, and one which will be very efficient and useful in operation.

With these and numerous other objects in view,v my invention consists in the novel features ofconstruction, combination and arrangement of parts, as will be hereinafter referred to and more particularly pointed out in the specification and claims.

A great many typists who are called upon to make copies and many readers, find it necessary; for accuracy and for purposes of avoiding confusion, to have a iineguide or indicator in op eration in connection with the material to be copied or read. Various types of line guides and indicators have been produced and various types of copy holders, with or without line guides, have been ofiered to the public, but 'most of them have proven to be too complicated, too expensive and in many instances ineffective or inefficient in use. My invention contemplates the provision of a copy holder which is comparatively light and inexpensive to manufacture, but sufiiciently r 3 designate corresponding parts throughout the several views and in which the numeral I designates a base member of weighted material, preferably metal, so that the same may constitute a support for the device and be free from casual upsetting or displacement. The one end of this base member I has mounted thereon, either by being formed integrally, secured thereto or otherwise, the cylindrical housing 2, which may be formed of metal or an other desired material. The outer end of this housing 2 is open and the inner end thereof has the outer face increased in thickness, as shown at 3, to form a disc-like projection thereon, there being threaded into said. end of the housing a shaft 4, the inner threaded end,being enlarged, as shown at 5. The outer end of the shaft 4 is reduced in diameter and also threaded, as shown at S, for a purpose to be hereinafter and more particularly set forth.

Mounted on the shaft 4 for rotation thereon is a reel 1, formed of plastic, hard rubber, metal or any other desired material, and upon which there is wound a metal tape 8, similar to the tape used in mechanics or carpenters tapes, that is,

the same is curved or arcuately bent to provide rigidity when extended. Removably held to the outer face of the reel I by means of the friction pins 9 is a disc It] which is, of slightly greater diameter than the reel so as to form a guide or abutment for the edge of the tape 8 on said reel, as clearly shown in Figure 6 of the drawings. The inner end of the tape 8 is secured to the reel by means of the screws I i, as shown in Figure 8 and said tape extends through a slot I2 in the peripheral wall of the housing 2. Any other desired form of securing means for attaching'the tape to the reel may be utilized.

The peripheral edge of the disc IQ is toothed. or otherwise serrated, as shown at I3 and loosely mounted on the shaft 4 is a lever I4, the free end of which is provided with a finger piece I5. Fulcrumed on the lever I4 is a dog It, the inner or operating end of which is adapted to engage the teeth I3of the disc ID. The dog is normally held in contact with the teeth I 3 by means of a spring member I! co-acting with the dog and the underface of the finger piece I5, as best illustrated in Figures 3, 4 and 6 of the drawings. The one end of the dog extending outwardly beyond the fulcrumed point is provided with a laterally extending finger piece I8, so that said dog may be released by pressing said finger piece I8 toward the finger piece I of the lever 94.

The housing 2 is provided in the front thereof with an offset or slotted portion I9 through which the lever I4 and its adjunctive parts projects, as best illustrated in Figuresfi and '7 of the drawings. The ends of this cut-out or slotted portions I9 form stops or limits for the movement of the lever I4. The lever is normally retained in its uppermost or raised position, as shown in Figures 1, 2, 3 and 7, by means of a wire spring member 20, one end of which is mounted in the inner wall of the housing 2, as shown at 2!, and the other end of which is mounted in an extension of the fulcrum or pivot used for the mounting of the dog I6, said latter connection being designated by the numeral 22. The intermediate portion of the spring 20 is wound about the shaft 4, as shown at 23.

An outer plate of disc-like design is provided for the opened end of the cylindrical housing 2. said plate being indicated by the numeral 24 and said plate is guided in position'by having a central reduced opening therein to receive there,- through the reduced threaded end 6 of the shaft 4, as clearly shown in Figures 6 and 9 of the drawings. The peripheral edge of the plate 24 is provided with a radially extending projection 25 which is adapted to be positioned below and in the path of the lever I4 to act as a stop or abutment for the latter, the purpose for which will be hereinafter and more particularly set forth. A nut 25 of disc-like design formed of plastic or any other desired material is provided, the central portion of which, extending from one face thereof, is threaded to engage the extended and reduced threaded end 5 of the shaft 4. The inner face of this disc-like nut 26 is provided with a central extension, as shown at 21, so that when the nut is turned home the inner projected portion thereof will abut the outer face of the disclike plate 24 and secure the latter in position over the open end of the housing 2. The inner face of said plate 24 has secured thereto in any desired fashion the leaf-spring members 28 which are adapted to abut the outer face of the disc I0, so that when the plate 24 is secured in position. said disc and reel l to which the tape is engaged will be retained in position against casual rotation, although it will be seen that through the medium of lever I4 with the dog I 8 thereon in engagement with the teeth of the disc, said disc, reel and tape may be moved against the frictional action of the springs 28. 7

When the plate 24 is positioned firmly in place by the nut 26, the extension 25 will limit the downward movement of the lever I4. Thus, movement of said lever I4 may be increased or decreased by adjustment of the plate 24 to posi tion the extension 25 further from or nearer the lever I4, as desired. Movement of the plate 24 on its axis may be accomplished by releasing the nut 26 and the plate locked in any adjusted position by turning home said nut.

The base member 2 has secured thereto to project upwardly and rearwardly a supporting plate or board 29. This represents a supporting board or back plate for material to be copied or read and in order to hold the material in place on this plate or board I have provided at the upper end thereof a pivoted clip 39, normally held in effective position by means of the spring 3I. While I have shown a form of spring clip in Figures 1 and 2 of the drawings, it will be understood that I am not limited to this particular structure, as.

any form of clip may be used without affecting the essential features of the invention herein.

The outer or free end of the tape 8 has removably secured thereto an angle plate 32. Formed on the edge of said plate is a guide strip 33 bent angularly to contact the edge of the supporting plate 29. A forwardly bent portion 34 provides a finger piece for drawing the tape upwardly along the face of the plate 29. Removably secured to the plate 32 to extend laterally across the face of the plate 29 is the line guide or indicator 35. Obviously, the line guide or indicator may be held in position across the face of the plate 29 to indicate lines to be copied from the material held on said plate and said line indicator will be positioned properly through the rigidity of the tape in position on said plate 29. As aforesaid, this tape obtains its rigidity through the curved or arcuate formation thereof.

Assuming that the tape is wound on the reel 1 and the device is set up for operation, it is first necessary to release the dog l6 by pressure on the finger piece I8 thereof so that the operator may grasp the finger piece '34 at the end of the tape and draw the latter upwardly until the line indicator or guide 35 is'positioned beneath the uppermost line of the copy held in position on the plate 29. As each line is copied or read, the lever I4 is pushed downwardly which through the action of the dog l6 causes the disc i and reel 1 to be partially rotated on the shaft 4, thus drawconventional and set by the typewriter manufacturers. To assist in the adjustment of this device to coincide with the spacing of lines on a typewriter, I have'provided a register orindicator.. One form of. indicator or register is illustrated in Figures 1, 3 and 5 of the drawings wherein there is removably mounted on the periphery of the housing 2 a plate 36 with four points spaced apart marked thereon and designated by the numerals 0, l, 2 and 3. The spaces between these marked points represent the spaces between lines of typing. Formed on the peripheral edge of the plate 24 at a predetermined point thereon is an indicating projection 31 which is adaptedv to co-act with the points marked on the plate 36. Thus, when it is desired to move the line indicator one space, the plate 24 is adjusted on its axis and locked so that the projection 21 registers with the point marked 1 on the plate 36. In this position of the plate 24, the,

lever stop 25 will be below and adjacent the lever H, as shown in Figure 3 of the drawings. Movement of the lever under such conditions will draw the tape downwardly and'positionthe lineguide one space below that to which it had been previously disposed. When the spacing between lines is triple, the adjustment of the plate 24 is made, as shown in Figure 5 of the drawings, so

that the projection 31 registers then with the numeral Son the plate 36. The movement of the lever I4 under such conditions is greater than the movement of the lever is permitted in the adjustment shown in Figure 3. Obviously, when the lever is moved downwardly, under pressure, it will be returned to its initial position under action of the spring 20 and in the return movement of said lever, the dog I6 is drawn over the teeth l3 of the disc I 0 without movement of the latter.

In Figures 16 and 17, I have shown a slightly modified form of the invention, insofar as the line indicator or register is concerned. In this form, the; housing Zahas mounted on its upper face through the medium of a screw 38 the four strips.39, 40, 4! and 42 of varying lengths, each of which is numbered to designate successive lines. The plate 240: has a bent projection 31a thereon which represents a pointer adapted to be brought in registration with the numbers on the strips, according to the spacing desired.

In Figures 18'and 19, I have shown a'further modified form of register or line indicator adapted for use are essential. is applied to the In this form'of the device, there housing 2b adhesive tape or strip- 43 which has points in spaced relation thereon.

indicated by numbers, as shown in Figure 18. Obviously, this adhesive strip may and replaced by another at any time. The plate 24b has a bent projection 31b formed thereon adapted for, registration with the numbered be removed markings on thetape or strip 43, according to the spacing desired.

From the foregoing description of the construction of my improved copy holder and line indicator, the method of assembly and the operation thereof will be readily understood, and it will, be seen that I have provided a comparatively simple, inexpensive and eflioient means for carrying out the various objects of the invention.

While I have particularly described the elements best adapted to perform the functions set forth, it is apparent that various changes in form,

proportion and in the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the principles of the invention. j
