The board lof the copy-holder is preferahly formed of. sheet metal bent todefine a front Wall or Web 2, side Walls'orflanges-'3 and 4 that extend rear wardly respectively from'opposite lateral edges of the front Wall 2, and a-shelf or bracket 5, that extendsfor- Wardly from the bottom edge of the front wall 2. A pair of ofiset plates-'6 are secured to the inner sides ofthe'flanges 3 and; l, respectively, at their lower anterior corners, and co-operate with :the adjacent portions of the web 2 and the flanges 3 and 4-, respective- 1y, to form vertical channels or sockets 7, adapted to receive'the vertical rods 8 ofa stand 9. The board 1 may be raised or lowered on the rods 8' and fixed at any desired or convenient level by tightening set screws 10, threading through theiplates 6, against the rods 8;

Ahorizontal shaft 11' is journaled at its opposite ends in the upper portions'of the flanges 3 11d 4, respectively; and another horizontal'shaft 12 isjour-naled at its oppo-' site-ends in the lower portions of the flanges 3' and l, respectively. it sprocket Wheel 18 is ri'gidly secu red to theintermediate portion of the 1 upper shaft 11 and a sprocket Wheel 1 tis rigidly secured to the intermediate portion of'the'lewer shaft 12:and in alinement With-the sprocketrwhee'l 13.- A sprocketchain passes around thesp'roc-ket Wheels 13 and 1L The links-of the'chain maybe formed of any suitable material and have any suitable shape, but in the present instance, for the purpose of illustration, they have been formed of wire bent to the desired shape. A horizontal bar 16 is secured to the chain parallel to and behind the front wall 2- of the board. Preferably, although not necessarily, a plurality of such bars is disposed at suitable intervals along the chain, two such bars being exhibited in the illustrative embodiment of the invention. In the present instance, the bars are secured to links 17 of the chain that are especially formed for that purpose. As shown in Figure 8, the ends 18 of the wires that form the links are bent to project outwardly, and the bar 16 is provided at its intermediate portion with openings 19 for the reception of the said ends. After the ends 18 have been passed through the openings 19 and the bar hasbeen pushed home against the link 1.7,"the ends 18 are bent back against the bar16, thereby securely attaching it to the link. The front wall 2 of the board is provided with slots 20 that extend along its respective opposing lateral edges, and the outer ends of the bars 16 extend beyond the said slots into guide channels 21, through which the ends travel as the bars 16 are carried along by the chain 15. he bars 16 are provided with arms that project through the slots 20. The arms are preferably, although not necessarily, pivotally borne by the bars 16, so that the slots 20 need. not be unduly long, the pivotal connection permitting them to swing into retracted position when they reach the end of the slots. Each of the arms is pivotedto its bar 16 through the intermediation of a stud 22, comprising a head 23 and a screw-threaded stem 24 that passes through an opening therefor in the ar 16 the head being clamped against that side of the'bar that is presented to the rear side of the board by means of a nut 25 screwed home against the opposite side of the bar onthe threaded stem 24. Flanges 26 project outwardly from each lateral edge of the outer face of the head 23, and a flange 27 projects outwardly from that horizontal edge of the outer face of the head 23 that is u permost when the bar is immediately behind the front wall 2 of the board. The arms are preferably, though not necessarily, formed in sections, one of the sections 28 being a member disposed between and pivoted to the flanges 26, and the other section 29 being a detachable extension for the pivoted arm member 28. The pivotal connection of arm member 28 to the flanges 26 is effected by a pin 30 that passes tightly through the flanges 26 and loosely through the arm member28. The member 28 is provided witha socket 31 to receive the detachable extension 29 with its axis-arranged transversely to the pin 30. A. set screw 32 secures the extension 29 to the pivoted block 28. The arms are biased, preferably by a preponderance of their weight being disposed at one side of their pivotal axes, so that they will normally tend to fall in a counter-clockwise direction when their bar 16 is positioned immediately 12 adjacent the outer side of the flan e 4,

and is rotated in a counter clockwise irection, as shown in Figure 4, by means of a pawl 34, pressed thereagainst by a spring 35, and pivotally borne by an operating lever 36, pivoted to the wall 4 by means of a stud 37. The anterior or outer end 38 of lever 36 is normally held'in elevated position by a contractile coil spring 39, one end of which is connected to the rear end 40 of the lever, and the other end to a stud 41, affixed to the flange 4. The movement of lever 36 is limited in one direction by a projection 42 on the outer side of the wall 4, and in the opposite direction by a lug 43 on the rear edge of wall 4 that is engaged by the nose of pawl 34. A cam plate 44, for optionally masking one or more of the teeth that the pawl 34 rides over at each stroke or throw of the lever 36, is loosely journaled on the shaft 12 and adjacent the outer side of the ratchet wheel 33. Plate 44 is provided with a plurality of circumferentially spaced notches 45, 46, 47 and 48, that ride under a roller 49, borne by a leaf spring 50, borne by the wall 4 so as to urge the roller 49 against the notched edge '51 of plate 44. The engagement of roller 49 with one or the other of the said notches prevents the plate 44 from being moved accidentally to a position other than the one of the four positions to which it has been set by the manipulation of the lever 52 formed integral with the plate. The proper positiomng of the ratchet wheel 33 is similarly assured b the roller 53, pressed into engagement wit the teeth of the ratchet wheel by the leaf spring 54, secured to the wall 4. When lever 52 is in the position shown in Figure 4, pawl 34 rides over 3 teeth at each operation of the lever 36, and the ratchet wheel 33 is rotated through an angular displacement corresponding to the circumferential distance occupied b three of its teeth. When lever 52 is pulled forward to engage roller 49 with notch 46, the arcuate edge 55 of masking plate 44 is rotated counterclockwise the distance of one tooth, permitting pawl 34, which is wide enough to also ride on the edge 55, to ride over only two teeth of the ratchet wheel, but engagmean ing the pawl to lift the latter out of "enga'gement with the third tooth, andthereby correspondingly limiting the angular mo'vement of the ratchet wheel. Similarly, when lever 52 is moved still further forward notch 47 engages roller a9, and the pawl 34 advances the ratchet wheel '33 over the circumferential distance of only one tooth. When lever 52 is moved to the extreme forward position, notch 48 engages roller 49 and arcuate edge 55'lifts pawl34= entirely out of engagement with the ratchet wheel 33, thereby permitting knob or disc 56, afrfixed to the outer end of shaft 12, to be rotated in a clockwise direction and to, ro-

tate ratchet wheel 33 and shaft 12 in the reverse direction to that effected by the operation of the lever 36. Of course, knob 56 can always be turned in a counter clockwise direction to rotate shaft 12, no matter what the position of lever 52 may be, and so constitutes a means for rotating shaft 12 rapidly in either direction. The pitch of the teeth of the ratchet wheel 33 is preferably such that the arms 29 are advanced a distance equal to a single space between successive lines of the copy or manuscript held on the boardeach time the ratchet wheel is rotated through the space of one 1-1;: tooth. It will, therefore, be understood 'tion shown in figure 2; but when the that the guide can. be advanced at single, double, or triple space intervals, as desired, by setting the lever 52 at the proper position corresponding thereto;

A Ushaped wire 57 has its ends pivoted in apertures 58 therefor in the upper ends of the walls 3 and 4. The wire'57 is urged against the front face of the board by a contractile spring 59 when it is in the po si wire is turned away from the boarduntil it abuts against the stop 60, home by the wall 4:,the spring 59 tends to hold it against the stop. The horizontal portion 6lof the wire 57 is preferably covered at intervals by sleeves of rubber 62, that bear against the sheet or sheets of paper, or the leaves of a book or record that may be clamped between the arm 61 and the wall 2 ofthe board. An L-shaped rod 63 has its vertical arm 64; pivoted in a socket v65 behind the board 2 and the wall 3, and the outer end of its horizontal arm 66 is adapted to ride yieldingly over a cam edge 67 on the upper end of the wall t. The camedge 67 is formed to provide a notch or depression 68 that serves to hold the arm 66 against accidental displacement from the position shown in Figure 2.

In using the device, the paper, manuscript or book 69 that is to be copied from is placed against the front face of the wall 2 of the board and clamped thereagainst by the wire clasp 57, as shown in Figures 1 and 2. Any

v preceding leaves of the book, that cover the page that isto be copied are turned back :iv'heel 33. The guide bar 71, having its lower'en'd. )ortions i'cutawa to rovide ed- 'es l .l P a 7 that limit its endwise movement, is "then placed-on the arms 29 against the copy 69',
