COPY-HOLDER.

SPECIFICATION forming part of 4Letters Patent No. 511,145, dated December 19,'1'893. Application tiled August 2, 1893. Serial No. I182,195. (No model.)

To @ZZ whom it may concern.-

Beit known that I, LOUIS HIRT, a citizen of l the United States, residing at Belleville, in the county of St. Clair and State of Illinois, have invented certain new and useful Improvements in Copy-Holders; and I do declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in copy holders; and it has for its general object to provide a copy holder of a cheap, simple, and eieient construction, and one through the medium of which the paper or manuscript may be readily moved so as to enable the operator to follow or trace the lines thereof.

Other objects and advantages of the invention will be fully understood from the following description and claims when taken in connection with the annexed drawings,in which- Figure 1, `is a front Ielevation of my improved copy holder with parts in section. Fig. 2, is an end elevation of the same. Fig. 3, is an enlarged transverse section taken. in the plane indicated by the line e, z, of Fig. 1. Fig. 4, is a detail section taken in the plane indicated by the line y, y, of Fig. 3, and Fig. 5, is a transverse section taken in the plane indicated by the line arm, of Fig. l.

Referring by letter to said drawingsz-A, indicates the supporting pillar or post of my improved holder, which may rise from any suitable base or pedestal; and B, indicates the main frame from which depends asleeve on, adapted to receive the reduced upper end of the pillar or post, which sleeve a, carries a set screw as b, whereby it willbe perceived that the frame may be turned and adj ustably iixed upon the post in a position convenient to the operator.

The main frame B, is preferably formed from sheet metal and it comprises the base plate c, the curved guide or flanged, extending upwardly and rearwardly from the for ward edge of the plate c, and the standards e, which rise from the ends of the plate c, as shown. These standards e, are provided with elongated apertures j', to receive the trunnions or shaft of the friction or pressure roller C, and they are alsoprovided with journal apertures to receive the trunnions or press the paper or manuscript against the' roller D, so as to enable said roller to move it through the machine.

Fixedly mounted upon the roller D, or the vshaft thereof is a ratchet wheel E, and loosely mounted upon the said shaft is an arm F, which carries a pawl lever G, which lis designed to engage and rotate the ratchet wheel E, and consequently the roller D. The swinging arm F, has a loop c', at its outer end (see Fig. 4), and in this loop the branch j, of the pawl lever is fulcrnmed on a pin or stud 7e, as shown. This pin or stud extends laterally from the arm F, and it is designed to be engaged by the branch Z, of the coiled spring m, which spring serves to return the arm F, to its normal position against the bar h, after it has been depressed to rotate the roller D.

In order to regulate the stroke of the arm F, and consequently the extent of each movement of the paper or manuscript, I have provided the adjusting screw H. This screw H, takes through a suitable bearing in the base plate of the frame B, as shown and it may be readily turned up or down according to the length of movement that is desired.

I, indicates what-I term the line follower or tracer of my improved holder. This follower or tracer is of a general bail shape and it has its branches m', curved as shown and pivotally connected to the bar 7i, whereby it will be seen that it may be yreadily raised to permit ot an interposition of manuscript between the rollers O, D, and that it will not in terfere with the free movement of the manuscript.

In the practical operation of my invention, the tracer I, is raised and the manuscript to be read 0r copied is passed over the flange d, and between the rollers O, D 3 the guide lug n, of the iiange d, serving to keep the paper straight. The roller E, is then rotated through the medium of the lever G, until the first line of the copy appears immediately below the tracer I, when the copying or reading may commence; the roller D, being turned as each line is finished so as to bring the next line beneath the tracer.

It will be readily perceived from the foreing description and the drawings, that my improved holder, is equally adapted for use upon a typewriter, a compositors case, or a reading desk or table; it being adapted to be mounted on many supports other than the pillar illustrated. It will also be seen that the holder is very simple and efficient and' that it may be produced at a slight cost which is a desideratum.

Having described my invention, what I claim is 1. In a paper holder,the combination with a mainf fra-mecomprisinga base platestand arde rising from theba'se plate, and a` curvedfiange: extending upwardlyL and rearwardly frontthe forwardf edge of the plate and having .1I-.guide n, and a bar h, mounted' in the standards of the trame; of a4 paper moving roll'erjou rua] ed iny thestarndardsof the frame, a friction roller yieldingly held against the paper moving roller, and? allait-shaped linetraeer orr follower loosely con-neetedtol the bar h, and. adapted toy rest upon'the paper as it passes; over the curved liange, substantially as specified.,

2; In a1. copy'holder, the combi-nation with a main frame, the bar h, supported therein, a paper moving roller .journaledl in the main framel andi carrying a ratchet wheel, a friction roller yieldingly heldagainst the paper movingl roller, anarm pivotally mounted on` the shaft of the paper moving roller, a spring adapted to'normally hold said arm again-st the bar h, and a pawl lever carried by the arm and adapted to engage the ratchet wheel of the paper moving roller; of a regulating screw taking through the frame and adapted to limit the stroke or movement of the pivoted arm, substantially as and for the purpose set forth.

3. The combination with a paper moving roller arranged in a suitable frame and having a ratchet wheel at one end; of a springpressed arm, a, paw] carried by said arm and adapted to engage the ratchet wheel and a screw having a suitable bearing and adapted to limit the movement of said arm in one direction, substantially asi specified.

4. The' combinationv with a paper movi-ng roller journfaledr in a suitable fram-e; of a yieldin gl y sustained4 pressure roller, aratchet Wheel:` secured to oueendy of` the paper moving roller, an armI arranged on the journalof said paper' moving roller, a pawl`r carried; by said-i arm and adapted to engagethe teeth of the ratchet, a stop forthe movement` ofsaidlarmand ratchet in one direction andia screw or they likel to adjustablystopisaid arm im an opposite direction, substantially as; specied.

In testimony whereof I aiiix my signa'tirrein presence ot two witnesses.

LOUIS` HIRT.
