Specification of Letters Patent.

Patented Nov. 14, 1911 Application filed September 20, 1910. Serial No. 582,919.

To all whom it may concern:

Be it known that I, GEORGE A. MARSH, a citizen of the United States of America, and resident of Washington, in the District of Columbia, have invented certain new and useful Improvements in Copy-Holders, of which the following is a specification.

This invention relates to copy-holders, the improvements embodying means organized cooperatively so that when a spacing key is depressed a line indicator will be caused to move one step downward for a predetermined distance, and the present invention comprises associated means for effecting a crumed thereon a rock lever 15, that has lon POSltlOIl by a spring 16, one end of th stepby-step movement of a line indicator over the copy'and in certain details of construction whereby a uniform depression of the spacing key will effect a predetermined downward movement of the line indicator over the copy, as will be hereinafter set forth and claimed.

The invention forming the subject matter of this application is illustrated by the accompanying drawings, in which- Figure 1 is a front elevation of a copyholder embodying my invention; Fig. 2, is a rear elevation; Fig. 3, is a vertical section taken on the line 3-3; Fig. 4:, is a horizontal section taken on the line 4-4; of Fig. 1; Figs. 5, 6 and 7 are detail perspective views of the carrier for the line indicator;

. Fig. 8 is a perspective view of the line indicator; Fig. 9 is a detail section on the line 8-8, of Fig. 8, Fig. 10 is a fragmentary view showing a modlfied form in which one of the bars carried by the platen is notched. Fig. 10 is a section taken on the line 10-10 of Fig. 10. Fig. 11 is also a fragmentary view of a further modification, and Fig. 11 is a section taken on the line 11-11 of Fig. 11.

The accompanying drawings illustrate a preferred form of construction of the invention which maybe modified as to details.

The platen 1 is provided at its lower portion with the usual ledge 2, said platen being maintained by a base 3 which has a hollow standard whloh receives a rod 4, that is held in its adjusted position by a set screw 5 that passes through a collar 6 and iminges upon the rod 4. The platen 1 has fast thereon a projection 7 that is secured to the slotted head on the upper end of the rod 4, and the platen is held at the*desired The ledge 2 of the platen has fixedly at tached thereto rearwardly extending sup ports 9, 9 which carry a bar 10, the spacin;

bar or key 11 being fulcrumed upon the ba 10 by means of arms 12, 12, and an interme diate arm 13 connected to the spacing be or ke is also fulcrumed upon the bar 10 an to said arm an angular link 14.- is attache by a pivot or bolt.

The rear face of the platen has fu] arm which is normally held in raise spring engaging the lever and the other cu of theuspring is attached to an adjustabl rod' that passes through an aperture bracket attached to the rear surface of th platen, said adjustable rod being screw threaded and is provided above the project Qing portion of the bracket with a'nut. Th

shorterarm of the rock lever 15 is connecte to one of the arms of a bell crank lever 1 by a flat bar or rod 18, said bell crank leve being fulcrumed to the platen so that it "upward extending arm will terminate slight distance below the upper edge of th platen, as shown. The spring 16, lever 1 and link 14 will hold the spacing bar 0 key 11 in normally raised position; with it arms 12 and 13 against the underside of th ledge 2 of the platen'l. The downwan movement of the spacing bar is about th same as the spacing bar of a typewritin,

machine and the force required to depres the spacingbar can be varied by adjustin the spring, the advantages of this arrange ment will be appreciated as copy holders 0 this type are used in transcribing from cop;

to a typewriting machine.

will be moved from its normal position away from the edge of the platen and that the extremities of the rod 20 are reduced for the passage of the apertured ends of the links 19 and 21 such reduction vproviding shoulders against which the apertured lateral extensions bear.

The platen 1 is provided at its upper end with parallel bars 22, 22 and one of the connecting means for securing the bars in place may be a bolt or threaded stud 23 which projects forwardly to carry a resilient arm or bar 24, one end being coiled about the stud, its other end bearing upon the copy to hold the same in place upon the platen, and the tension of the spring or resilient arm may be varied by the thumb-nut that engages the threaded stud 23.

The underside of the ledge of the platen 1 adjacent to one side is provided. with an angular extension 25 and to the lower end thereof is secured parallel bars 26, 26, of practically the same dimensions as the bars 22, 22 attached to the upper end of the platen. The outer ends of the bars 22 and 26 are connected by astrip or bar 27 which is of about the same thickness as the thickness o'fthe platen and in practice the bar 27 will be provided with shoulders that correspond as to thickness with the thickness of plates or filling pieces between the rear bars 22 and 26, to provide a space of sufiicient size to receive the reduced ends of the laterally movable rod 20. The platen 1 at a suitable distance from its upper edge and the angular extension 25 have threaded apertures like apertures in transverse alinement being formed in the bar or strip 27 for the reception of screws which hold in removable engagement flat strips or bars 28, 28 each having registering countersunk apertures and the screws hold in place not only the bars 28 but also ratchet bars 29, 29 which have holes or transverse slots to permit a limited range of adjustment of'the ratchet. bars which are held in place to pro ject slightly beyond the inner edges of the platen and the bars or strips between which the ratchet bars are held.

The ratchet bars 29, 29 are each secured in place so that theinclined portion of the teeth will extend upward and in ractice there may be used ordinary saw-bladbs with the set taken out when the copy holder is to be used for ve fine work, as the movement of the line indicator downward over the copy is only limited by the spacing of the teeth. In practice instead of using ratchet bars made up of saw blades the edge of the platen may be serrated or notched and opposite thereto the inner side of the bar 27 i may be notched, or as a full mechanical equivalent thereof the bars 28 may be formed with ratchet teeth.

Fig. 10 of the drawings shows a modification wherein a bar 27 has notches, serrations or ratchet teeth formed in its edge which is nearest to the platen 1, and in this modification a similar bar is attached to the rear of the platen so as to extend beyond the edge of said platen. The bars 27 each have teeth 29 formed therein.

A further modification is shown by Fig. 11, wherein a bar the same as shown by Fig. 10 is used, but in the modification Fig. 11 the edge of the platen 1 which is nearest to the bar 27 has notches, serrations or ratchet teeth formed therein.

The slide'30 which is mounted upon the laterally movable rod 20 comprises two members or parts which form with the means heretofore described the support for the line indicator 31. The part or member 32, illustrated in detail by Figs. 5 and 6 is formed of-sheetmetal shaped to provide at its upper and lower portions projections 33 and 34 which have openings 33' and 34' therethrough for the passage of the rod 20, the upper projecting portion which extends farther rearward than the lower one has a threaded aperture for the reception of a set screw 35 that carries a lock nut 36. The longitudinal portion of the part 32 has below its center and on the side adjacent to the platen a fqrwardly projecting part 37 adapted to pass into the socket formed at one end of the line indicator and on the opposite side of the longitudinal portion from the projecting part 37 there extends a rearward extending part 38, such part having a part that extends substantially parallel with the longitudinal portion and provides a stop 39 for the other member of the slide. Attached to th e part or member 38 of the slide 32, for engagement with the outer ratchet bar 29, there is a pawl or detent 40 that is preferably made up of a flat iece of spring steel the ends thereof being entas shown, and this type. of pawl is held in'place by a screw and a cross piece 41. The front face of the longitudinal member of the slide has adjustably attached thereto a gage-plate 42, the purpose of providing such a gage-plate being to furnish an indicator for the pointer on the other member of the slide, the range of adjustment of the gage-plate being coordinated with the distance between the ratchet teeth on the bars 29 and when three gage-marks are used they will indicate close, medium and wide spacing or movement of the line indicator, to register with the spacin of type written copy or standard rullng o stationery.

The member 43 of the slide 30, as shown by Fig. 7, comprises acentral portion 44 the ends being bent at right angles such projecting portion being apertures 45 and 46 for.

the passage of the rod 20, the blank from which the member is formed has at its upper end lateral extensions 45 and 46, one extension 45 providing a part with which the set screw 35 will engage and the other a hooked shapev part 46 that serves as a pointer the end of which overlies the gage-plate. The central portion 44 carries at an intermediate point a pawl or detent which is somewhat longer than that on the other member of the slide this pawl or detent 47 being connected to the part 44 by a screw which also holds in place a plate or arm 48, and to the arm or plate 48 is secured an arm or plate 49 that is bent at its end similarly to the arm 48.

The members 32 and 43 of the slide are assembled upon the rod 20, when the same is detached from between the guide bars, by first placing the members of the slide together so that the pointer 46 will overlie the gage-plate 42 and the projecting part 45 will underlie the set-screw 35, the apertures being in alinement the members may be placed upon the rod 20 and when the rod is positioned between the slide bars 22 and 26 the pawl or detent will engage the ratchet bar 29 that is partially overlaid by the platen, being held against the same by the action of the spring 16.

In operation the line indicator is moved to the upper portion of the copy support,

the operator grasping the projecting part 31 p of the line indicator, the sprlng pawls or escapements either being pressed toward the slide or allowed to ride over one of the ratchet bars. The copy is held against the copy support by the spring 24 the lower edge of the copy resting upon the ledge 2.

By turning the screw 35 the slide may be set to determine the fall or downward move ment of the line indicator, which will be equal to the distance or space between the lines of the copy. hen the key or space bar is depressed the motion will be converted and transmitted to the laterally mov- I able bar or rod 20 which carries the slide,

downward movement of the spacing bar against the action of the s ring movingthe bar away from the edge 0 the platen a distance suflicient to release the pawl or detent 47 from the ratchet bar with which it engages and such lateral movement will cause the pawl to engage the opposite ratchet. When pressure is removed from the bar. spacing bar the spring will return the rod 20 to its normal position, and thel'ateral movement of the rod 20 is such thatv one pawl will always be in engagement with its moving the pointer over the gage-plate carried by the art against which the screw impinges. T e purpose of having the gageplate adjustable is to provide for difi'erent and means for shifting the rod.

widths of spacing" such as may be incident to different makes of typewriters or different diameters of cylinders.

In moving the escapement, which is practically two sliding collars with pawls,'the' collars or members having abutting portions at their upper ends, the pawl adjacent to the edge of the platenis pressed inward to prevent the pawl dragging over the ratchet bar in its upward movement.

The construction of the arts may be varied as to details not speci ed in the claims.
