COPY-HOLDER.

Application filed March 30, 1918., Serial No. 225,712. Renewed June 24, 1919.

To all whom it may concern:

Be it known that I, ELMER GRAHAM, a citizen of the United States, and a resident of NVray, in the county of Yuma and State of Colorado, have invented a new and Improved Copy-Holder, of which the following is a full, clear, and exact description.

This invention relates to copy holders for use by typ'ists or others making transcripts of records and has particular reference to a device of this character that is designed to hold in a convenient and reliable manner a more or less voluminous quantity or roll of the matter being copied.

Among the objects therefore of the invention to provide a copy holder comprising a hollow cylindrical casing, having two parts hinged together longitudinally of the casing and having means to hold the parts closed but with the sheet or sheets being copied projecting radially from within the casing along the joint or meeting line of the two easing parts, while the bulk of the matter is housed within the casing.

A further object of the invention is to provide certain improvements relating to the spacing means controlling the rotation of the casing according to predetermined angular amounts, such amounts being calculated according to the width of the lines or other conditions.

Another object of the invention is to provide improved means for controlling the gripping of the paper and the releasing of the paper with respect to the casing.

With the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which- Figure 1 is a front elevation of the casing and parts immediately associated therewith.

Fig. 2 is an elevation of the left end of the device with the lower portions in section on the line 2-2 of Fig. 5.

Fig. 3 is another elevation of theright end of the device.

l ig. -it is a vertical transverse section on the line 4-4 of Fig. 1.

Serial No. 308,489.

Fig. 5 is a vertical section of the base on the line 55 of Fig. 2.

Fig. 6 is a sectional detail on the line 6-6 of Fig. 3

Fig. 7 is an enlarged view indicating the means to rotate or control the rotation of the casing, and Figs. 8, 9, 10, and 11 are diagrams showing the different stages of the operation of the bail upon the sheet of paper during the operation of the device.

Referring now more particularly to the drawings I show a base 10 of any suitable nature providing for the support of a standard 11 in upright position. This standard is shown as comprising two plate members anchored to the base by screws or bolts. Between the upper ends of the plates is clamped an arm 12 by means of a clamping bolt 13 having a winged nut for hand operation. In the upper end of this arm 12 is clamped a crossbar 14 'by means of a bolt 15 whereby the crossbar 14 may be adjusted angular-1y around its axis irrespective of the inclination of the upright arm 12 with respect to its clamping bolt 13.

The main part of the copy holder comprises a hollow cylindrical drum or casing 16, the end portions of which are journaled coaxially in a pair of brackets 17 and 18 extending forward parallel to each other from the ends of the crossbar 1 1. The pivot.

means comprises a short shaft 19 for each end of the casing having on its inner end a binding nut 20 and on its outer end a finger piece 21 whereby the casing may be rotated conveniently and quickly by hand from either end. Said casing is divided longitudinally along a plane at one side of the axis of rotation thereof, the two parts 16 and 16 thereof being hinged together around an axis 22 represented by a rod extending the full length of the casing through a pair of cars '23 formed on one of the parts and overlappingthe perforated portions of the other part. A spring 24 is arranged between the two parts of the casing in any suitable manner so as to tend to throw the cover portion 16 open. As indicated this spring has its ends fixed to studs 2 1 and 24 fixed to the parts 16 and 16 respectively. The force of this spring to throw the easing open is limited by means of a link 21 pivoted to the stud 24: and having a slot through which the stud 24: projects. The

r The outer action of the spring, however, is normally resisted by a pair of catches 25 secured upon the ends of a rod 26 extending through the front portion of the casing just below the line of contact between the two'free edges of the casing parts. These catches 25 cooperate with lugs-27 extending from; the

ends of the part 16", and since the catches are both mounted rigidly upon the same rod 26 they are both moved in unison. A spring 28 coiled within the casingaround the rod 26 tends to hold the catches in locking position or engaged overthe lugs 27. -When the portion 16 of. the casing is swung to lts' closed position the lugs 27 ride over the cam portions 25 of the catches soas to deflect the catches against the, force of the SPIHIQ' 28 for the purpose of allowing the lugs 2 to snap in behind the hook portions of the catches. When the lid portion of the casing is open the catches 25' are maintained in proper position to be engaged by the lugs 27 by means of a stop lug 29 carried by one orbothof the ends ofthe main portion 16*. end of one catch 25 is provided with an outwardly projecting wing 30 whereby the operator by the use of his thumb or finger may release such catch from' its lug'27 and by reason of the rigid shaft 26 the other catch will be released at the same time. i V

31 indicates a sheath of substantially semi.- cylindrical form secured at its rear edge to the crossbar '14 and extending beneath the casing. The front edge portion of the sheath constitutes a line gage at 32 cooperating dire'ctly with the'front portion of the casing V or with the sheet of the copy rolled thereon.

(See Fig. 4). sheath is mounted upon a rod 33 which projects through pairs of ears 34 formed coincidentally with the formation of openings 35 in said sheath to accommodate a plurality of rollers 36 journaled upon the rod. The ends of the rod are supported in a pair of hangers 37 and 38 hung respectively-upona and 38 at the front ends a finger piece or lever 39which when pressed rearward lifts the rod 33 carrying its hangers 37 and 38 and the, front portion of the sheath away from the casing releasing any hold thereof upon the paper.

As a'further description of the operationof the rotatingcylinder, serving as a casing or holder, for a rolled book or rollv of manuscriptto be copled and whose two relatively parts serve as a gripping holder movable for the upper, end of a sheet to be copied,

mechanism externally erating with the sheet gage and guiding means, and also the bail including the bar 52 serving tothrow the of the: roller cotploose lowerendofthe sheefiovero'ut "of "Said front portion of the nection it is of paper as a line therange of the operators vision, Fig. 8 indicates the relation of the parts above mentioned at the moment of the gripping of the upper end of the sheet S between the two parts of the cylinder, the paper being thus held in gripped position by cooperation between the catches 25 and lugs 27. It will be understood that the parts just referred to coeperate in the manner illustrated upon a single loose sheet in substantialy the same manner as upon a sheet protrudingthrough the casing from a roll or book within the casing. Fig. 9 is a view similar to Fig. cylinder after a complete rotation thereof, all of the sheetex'cept the lower end being wrapped around the cylinder and the bail shown in full lines as about to bereleased to throw the loose end of the sheet upward and rearward to the dot and dash line position shown at the left side thereof. It will be understood that during the rotation of the cylinder between the positions of Figs. 8 and 9 the bail bar 52 by riding or wiping over the rear portion of the stationary mechanism will be brought down upon the outside of the cylinder and into the groove or pit 52 provided therefor at the front or free gripping edge of the upper port1on 16 cylinder. After the, sheet is gripped as indicated in Fig 8 the operator by a simple movement gives a quick spin or rotation of the cylinder and at the end of this rotation, as indicatedin F ig9, the loose or lower end of the sheet way by the swinging of the bail around its axis 51 and bythis time the first line of matter on the sheet will be brought into view just abovethe line gage Fig. 10 indicates the result of the succeeding step by step actuation of the cylinder as" a result of the transcribing operation. This figure shows the lowerend of the sheet as still being located between the line gage or griping rollers and cylinder. At this coni to be noted that the operation of the device is not dependent upon any particular length of sheet. Fig. 11 is a view showing the action of the bail and upper part 16 of the cylinder when the extension 39 is pressed rearward far enough to open the cylinder, it'being remembered that the first part of this actuation of theiextension 39 serves to release the gripping rollers and line gage while the latter part releases the catches 25. The preferred construction is such that the circumference of the cylinder approximately equals the length of the sheet, but if the sheet is longer and is wrapped more than once around the cylinder it ma 1 be necessary to reverse the rotation of the cylinder slightly by the operation of the hand upon one of the knobs 21 to effect the release of the and between the sheet and the is thrown over out of the- 8 showing the can be manipulated in no other we sheet and opening of the cylinder as shown in Fig. 11. This apparatus is designed especially for copying or transcribing from ordinary folded court files or abstracts that as conveniently as within the hollow cylinder.

At either end of the device, prefe 'ably at the right, the short shaft 19. This lever carries a pivotally mounted pawl 11, the point ofwhich projects upward for cooperation with a fine toothed ratchet wheel 42 concentric with and fixed to the axis 19; A light spring 43 is connected to the pawl for the purpose of causing the point of the pawl toiengage the teeth of the ratchet wheel when the lever 10 is lifted to actuate the casing. The pawl, however, is provided with a rearwardly projecting rounded end 44; cooperating'with a V-ended stop so connected to a bracket -15 fixed to and extending downward from the bracket 17. These parts are so designed that when the lever 10 is returned bythe spring to its idle position .the rounded end or tail piece M of the pawl is received into the V of the stop 45 whereby the point of the pawl is withdrawn from the ratchet wheel against the force of thelight spring 453 so the pawl is normally held free from theratchet wheel and thus the operator by grasping either of the wheels or knobs '21 may rotate the casing rearward as well as forward at any time. \Vhen, however, the lever 4L0 is lifted to actuate the casing forward the pawl 41 will immediately engage a tooth of the ratchet wheel since the tail piece thereof will-immediately leave the notch or V of the stop 4:5.during such movement of the lever 10. The stop 15 consequently constitutes a means ,to limit the downward movement of the lever 40.

The front end of the bracket 17 orv any device connected thereto serves tosupport an adjustable carnv shaped abutment 46 pivoted at 7 to the bracket. The bracket is provided with a'series of notches or pits -18 into which a spring operated stud 4:9 is adapted tosnap and temporarily hold the cam 4:6 in any desired position. The portion of the bracket having the holes or pits 48 is preferably graduated to represent various widths or distances between lines of matter to be copied. The finger piece 46 of the adjustable cam thus operates between relatively fixed cars 16 but projects forward therefrom so that the manipulation of the cam may be easily effected by the operator by compressionaction, grasping said finger piece and the ear toward which it is to be moved between the thumband finger so that the ear constitutes a fixed abut ment or'fulcrum to make the action positive and reliable.

At 50 I show a pair of levers connected to the ends of a rock shaft 51 on the out- I provide a lever 40 pivoted uponv side of the ends of the cover section 16 of the casing, the outer ends of these lovers are connected by a steel ribbon 52 or the like. Said rock shaft 51 is controlled on the inside of the casing by a spring 53, the tendency of which is to throw the bail constituted by the two lovers and steel ribbon rearward while the casing is being rotated. The rear or convex edges, however, of the levers 50 are adapted to ride upon rubber rollers 11 mounted upon the crossbar 1.4: whereby the steel rib'bon 52 is swung inward against the surface of the casing while the casing rotates, the length of the lovers being so designed that said ribbon will just bridge over the joint between the free edges of the casing parts thereby relieving any depression or offset for the rollers 36 that otherwise would be incident to the edge of the casing which preferably is made somewhat rounded to prevent any damage to the sheets of copy projecting therefrom.

1n the practical operation of this copy holder any number of sheets such as a note book, loose leaves or part of a roll of matter to be copied are projected outward and downward over the line gage portion of the sheath, the bulk of the note book or other collection of sheets or leaves pertaining to the same copy being rolled up in any convenicnt manner and placed within the easing. The casing will now be closed either preliminary to or as a. consequence of the rotation imparted thereto by one or the other of the finger pieces or knobs 3'1. \Vhile the casing is thus being given a complete rotation the bail is rolled between the sheet and easing so that when the rotation is complete and the ribbon portion of the bail passes the line gage the spring 53 pertaining thereto will snap the bail upward and rearward, causing the end of the sheet to be carried rearward therewith and held out of the line of vision and thereby the sheet to be copied beginning at its upper end is presented in proper position for this purpose. In this condition the casing may be given a step by step rotation until the sheet is eopied,-then by touching the wing 30 the casing may be opened and another sheet will be adjusted for treatment in the manner already described. In withdrawing the sheet from the machine, the line gage or sheath will be released therefrom by applying the thumb or finger to the extension 39. 1-\.ttention now called to a wing 54- shown as constituting a rearward extension of the hanger 38 and having an are shaped rear edge cooperating with a lug 55 formed on the adjacent hook 25. The curvature of the wing edge is such that in normal position the lug 55 as it is carried with the hook around the axis of the casing j'iasses along a path parallel to but spaced slightly from said'edge. The finger piece 39 in addition knob 21 and apply his thumbjto piece 39 whereupon an easy pressure 'on'the throw the hangerSS around its pivot 38 and-so release This brings the curved edge of the wing 5-1 into wiping engagement with" that the paper may be'releasedto serving to release the line gage from its gripplng position on the paper also constitutes a'ineans to open the casing.- Thegrasp thef the finger operator to release the paper will finger piece Will immediatelythe paper.

without opening the casing if desired, or if the casing is lease both of the hooks 25. Obviously the extent of swinging movement of the hanger 38 or wing 54 in the act of releasing the" paper, but without releasing the hook, will depend uponthe normal clearance between or the length of the" the lug 55 and winged: hooks that extend beyond the lugs '27. I thus provide a simple mechanical contrivance, one that is easily manipulated for accomplishing two distinct objects or func-' tions. The length of the arc of the Wing 5% is such that the wing will engage the lug 55 for the purpose of unlocking and opening the casing atany point in a considerable range relative to the joint in the casing be yond the line gage. fore, that when'the finger piece 39 is actuated to cause the unlocking and opening of the casing by reason of the cooperation between the wing 54 and the lug .55, not only willthe casing be opened so that the material therein may be removed, but also the same action of the finger piece in lifting theline gage away from the casing or sheet will insure as may be desired;
