Specification of Letters Patent. Patented NOV, 19, 1912, Application 1ed January 22, 1912. Serial No. 672,664.

2. Revolubly mounted in the side bars of the frame near the forward side thereof is a supporting and operating shaft 3 having thereon a sleeve or tube 4. Loo'sely connected at its lower end to the sleeve 4 on the shaft 3 and extendingupwardly and rearwardlyat a suitable angle is a copy supporting plate 5, said plate being preferably formed of heavy sheet metal having its side edges bent rearwardly at right angles to form flanges 6 in the lower ends of which are formed openings which receive the shaft 3 and sleeve 4. The plate 5 is adjustably supported at the desired angle by brace bars 7 pivotally connected at their upper ends to the side flanges 6 of the .plate and having in their lower ends thumb screws 9 which engage the slots 2 in the sides of the base frame and are adapted to clamp the lower ends of the brace in engagement with said side bars thereby securely fastening the brace to hold the supporting plate in the desired position, Fixedly mounted on the shaft 3 adjacent to the outer sides of the flanges 6 on the copy supporting plate are sprocket gears 10 which are connected by sprocket chains 11 to sprocket gears 12 revolubly mounted on bearing screws 13 arranged in the side flanges 6 on the Supporting plate.

Arranged across the copy supporting plate is a line guide bar 14 which is preferably formed of sheet metal and has its upper and lower edges curved upwardly to a slight extent to prevent said edges from catchinA into any rough places or obstructions w1th which the bar'may come into engagement when being moved Page attaching bars 15 to lugs 16 on one of the links of each of the sprocket chains 11 whereby whenthe chains are moved in one direction or the other a corresponding move` ment will be imparted to the guide bar. By loosely attaching the bar to the chains as herein shown and described the bar may be swung upwardly or outwardly to any de- To all whomV it may concern.'

Be it known that we, DERMONT H. ROB- ERTS, a citizen of the United States, resid` ing at Pocatello,eounty of Bannock, State of l-daho, and JAMES PETERSON, a citizen of the United States, residingat Price, in the county of Carbon and State of Utah, have invented certain new and useful Improvements in Copy-Holders; and we do del clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements lin copy holders. I

One object of the invention is to provide a copy holder having a line guide bar provided with an improved construction and arrangement of operating mechanism wherely the same may be brought down the page of the copy as the lines are read or transcribed therefrom, and which may be rapidly shifted back to the top of the holder after the last line on the page has been read.

Another object is to provide a copy holder of this character in which the line guide bar maybe adjusted or swung outwardly from the copy supporting plate to permit copy or books of different thickness to be placed beneath the guide bar.

With these and other objects in view the invention consists of certain novel features of construction, and the combination and arrangement of parts as will he more fully described and claimed.

In the accompanying drawings; Figure 1 is a side view of our improved copy holder; Fig. 2 is a front view of the same; Fig. 3 is an enlarged front view of the lower end of the holder and operating mechanism for the line guide bar, parts bein broken away and in section; Fig. 4 is a site view of one end of the part shown in Fig. 3 illustrating the construction and arrangement of the releasing devices for the operating mechanism of the guide bar; Fig. 5 is a detail of the drive shaft and sleeve for the copy operating mechanism; Fig. 6 is a detail perspective view of the clutch shifting member of the device.

Referring more particularly to the drawings, 1 denotes the base of the holder, said base being preferably -in the form of a recright angles to orm a rest 17 to receive the tangular frame having`in its opposite sides book or copy2 the upper edge of which is near its rear ends horizontally disposed slots held by a spring clip 18, vsaid clip compris plate, thus permitting books or copy of any thickness to be placed beneath the same on the supporting late. The lower end of the supporting ate 5 is bent upwardly at across the f The bar 14 is loosely connected bvV sired distance beyond the outer side of the metal plate riveted or otherat its inner edge to the rear wise secure side of the supporting plate 5 and having its ends forof which the levers are actuated bythe op- 25 to which is connected erator. On the shaft 3 adjacent to the right hand lever 20 is fixedly mounted a ratchet gear- 22 with which is adapted to be engaged an operating pawl 23 pivoted to the `lever 20 and with which is also engaged a spring projected locking pawl 24 pivoted on the base frame and which holds the gear against rotrograde movement. The pivoted end 'of the lever 20 has formed one end of a coiled spring 26 the 'other end of which is secured to the adjacent side of the base frame 1. Arranged on said side of the frame are lugs 27 having interiorly threaded passages with which are engaged a stop screw 28 with thev inner end of which engages the stop lug 25 and limits the movement thereof by the spring 26. Also arranged in this side of the frame 1 is a stop pin 29 which is disposed in the path of movement of the lug 25 and is engaged by the latter when the finger bar 21 and levers 20 are depressed, thus limiting the downward` movement of said levers and bar. 1

By means of the operati mechanism just described the shaft 3 isnriven and in order to impart the movement of the shaft tothe sleeve 4 thereony and to the sprocket gears and chains for moving the guide bar, we provide a clutch connection between the opposite end of the shaft andsleeve. The

Vclutch connection between these parts comrises a'clutch member 30 which is slidably keyed to the opposite end of the shaft from that to which the ratchet gear 22 is secured, said clutch member 30 being adapted to be forced inwardly and normally engaged with a clutch member 31 formed on the adjacent end of the sleeve 4 by a coiled spring 32 arranged on theend of the shaft between a stop collar 33 thereon and the end of the clutch as shown. When the shaft and sleeve ed are thus locked together it will be Aseen that j move the guide the movement of' he shaft by its operating mechanism will turn the sleeve 4 and the sprocket chains thereon the proper direction for operating the sprocket chain to bar 14 downwardly in a step sleeve 4 are actuated to` thereon a stop lug -43 with greater or less pressure by step Amovement across the page ofthe copy.

In order to quickly *move the guide bar back to the upper end of the supporting plate v5 after the bottom of the page has been reached, we provide a retracting mechanismcomprising a coiled spring 34 arranged on and having one end secured to the sleeve 4 and its opposite end to one-of the flanges 5 of the supporting plate whereby when said sleeve is turned to move the guide bar downwardly the spring will wound up on the sleeve sol that when the latter is released the'force of the spring will be applied to revolve the sleeve and gears 20 in a reverse direction, thus causing the chains 11 to retract the guide bar by pulling it back up to the top of the holder.

I-n order to disengage the clutch member 30 from the clutch member 31 on the sleeve 4, we provide a clutch releasing mechanism comprising a frame 35 which is slidably-engaged with the clutch members and has its upper end offset to form an inclined or cam clutch engaging surface 36 which, when the aok frame is depressed or drawn downwardly f into engagement with the inner surface of the head 37 formed on the outer end of the clutch member 30, thus retracting said clutch member against the pressure of the spring 32 and out of engagement with the clutch member 31 on the sleeve. rI`he frame 35 is depressed or pulled downwardly by a clutch releasing lever 38 vpivctally mounted at its inner end on the adjacent side of the base frame 1 and having a pivotal connection near its outer end in a recess 39 in the lower end of the releasing frame 35. On the outer end of the lever is arranged a knob or finger engaging plate 40 whereby the lever may be readily depressed to pull the fra-me 35 downwardly. The lever 38 is provided at its inner end with' a retracting spring 41 by Y lever and the clutch shifting frame 35 are will be brought brought upwardly to inoperative positions l after being depressed and released by the operator.

In order to prevent the spring 34 from moving the guide bar 14 upwardly 'at too great a speed and to provide means for quickly stopping the bar at any desired point, we provide a prising a flange 42 formed on `the inner side of the clutch releasing frame 35, said iiange having a segmental is adapted to be brought into engagement with a hub or annular boss 43 on the outer surface of the sprocket gear 10 or the adjacent end of thesleeve 4. By meansof the braking mechanism just described it willbe seen that the flange 42 may be brought into frictional engagement with the hub or boss brake mechanism com-` inner surface which, when the clutch shifting frame is depressedr by the lever 38, thus placing the retracting or upward movement of the guide bar under the perfect control of the operator.

From the foregoing description taken in connection with the accompanying draw ings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the prin# ciple or sacrificing any of the advantages of the invention as claimed.
