The

inder5,,with v pantsbroken awayto show the i 23.; .Asa material 23 iorthe cylinder 20 I I find transparent celluloid to be well adaptfold is intended to add strength and firmness to the end'of the cylinder-forming material and isretained across its width by means of a tube25, through WhlOlT is driven a rod 25 bearingyat its opposite e11ds,,in- ;the cylinderrend-members, the tube 25 serving also as a spacing element between the op-" posed end membersof the cylinder. 'The scroll end of the cylinder is supported by a similartrod 26 and tube 26*. The tend: ency of this endto unroll produces suflicient pressure against the folded end 25 of the same material to hold a sheet or a number of sheets of copy paper P (Fig. 4) initially while being additionally clamped in manner to be explained. l

The cylindrical holder thus formed is free to'turn either on or with a hollow shaft 13 and this shaft 13 is free to turn on supporting arms 1 (Fig, 3) which are slightly bent or relatively sprung before being inserted in the shaft in order that the proper amount of friction may be maintained constantly and unvaryingly without the necessity for lubrication or time-to-time adjustment; similarly, v a proper and dependable frlction is maintained between the hollow shaft 18 and the cylindrical holderby means of spring-clamps 28 and29- These are the copy clamps and are mounted on the opposite arms 30, 31 which are integral with the hollow shaftrl3; hence the, clamps may be moved manually independently of the cylinder (or vice versa) as a convenience in placing the copy on the holder, but the copy having been placed and adjusted the clamps and cylinder thereafter move together around the friction arms 1 functioning'as an axle. The amount of friction between the arms 1 and hollow shaft 13 is intended to be the minimum amount requisite to prevent the turning of, the cylinder as a result of jar by reason of' its being slightly moi-weighted on one side either structurally or because of the unequal distribution of weight of the copy when placed on itythe objective'being to offer as little resistance as possible to the typewriter carriage when connected as herein described to automatically rotate the holder and copy paper'held thereon. V

In addition to their function as a brake between the cylinoer and hollow shaft, the copy clamps are so designed that they will con-- ceal little or none of the copy when held between them and the holder. To this end, they are each formed ofa single length of spring wire and stiffened throughout their horizontalor clamping reach by driving on them a tube 28, the projecting ends of the enclosed spring wire then being so shaped that they'may be sprung into holes 30, 30

provided for that purpose through the opposed arms 30,'31.' One'28 of the clamps is intended to be stronger than the other ant to that end functions as a self-spring with its fulcrum or fixed point 28 inside or short of the cylinder center 19 so that when the horizontal reach 28 of the clamp is pressed back around the cylinder space between the clampand cylinderwill be provided for corn -V3l116I1C6 :n inserting copy of certain kinds and lengths not readily secured otherwise. The angular ends 28"'(F1g. 3) of the clamps '28 protrude through the arm 31 a sufficient which engages a shoulder 3O on the arm when employed in the position shown in Figure 4: and contacts withthe edge 30 of the arm when in the position shown in full lines in Figure 5. The shoulder 29 also provides a means for attaching a coil spring 32. se-

cured at its inner end to the tubular shaft 13.

the outer end of this spring carrying across; the pivot end ofthe clamp and serving to hold the clamp in either of its reversed and reversible positions. It will be noted that thisjclamp is so shaped-that whenin the position shownfin' Fig. at its selfsidearms are outside the circumference of'the cylinder for a certain distance, thus permittingcopy of unusual width to project beyond the ends of the cylinder. This is also true of the other clamp- 28; A purpose in rendering thr clamp 29" reversible is to" provide several varying distances between the two clamps for holding copy of correspondingly varying short or long lengths and which may beof too flimsy a character to clamp in the more usualmannerin the mouth 27 of the cylinder. Because of the small size of the clamps it is not necessary to employ both of them in clamping copy started in the mouth 27, theirsmall size permitting copy to pass orerthe unused clamp or the unused clamp may pass beyondthe end of the copy, as conditions warrant; It will be noted thateither clamp, and especially the one designated 28' is readily removable, and it may be removed when it desired to employ a special device shown in Figs. and 9 for holding copy of unusual stiffness, for example, and which could not be securely held in the mouth 27 of the cylinder or would tend to injure the shape of the cylinder-fornung material if so held. This consists of a pair of split rings 54. The opening in the rings permits their placement on and removal from the copy cylinder past the bail 38 and frame arm 1* andalso provides space for one of the clamps above describec, which may be used in connection or not according to character of copy and preference of the operator. The rings may be formed of a wide outer mar- 54 i thieliiiess i ftransparentlrand relai'dercnt witl' Prel'mina-ryto an explanation of the manner lot automatically operating the copy holder from the.carriagev of. a typewriter machine I willinow describe the support ng frame and operating devices attachedthere .to.

The flanged disc 33v and pawl 35 comprise atoothless ratchet-setwhich permits of an adjustment unrestrictedin degree within the maximum amountestablished'in manner exposition as the carriage (1 moves plained. The pawl 35 is provided with a.

notchSf) (Fig.4?) whichreceives thefiange 33 of the disc. When the pawl rises with the outer endof the 'fulcrumed lever 34 the pawl exerts a wrench-like grip and pull on 33 thus turning the cylinder 20 which is mounted on the tubular shaft 13 in common with the'disc 33. The associated adj ustingmeaiis for determining the degree of movement 'ofthe cylinder is comprised of a channeled arm 36 carrying a spring 137 (Fig. 4). This arm-P6 is placed on the supporting arm 1 with the spring permanently under tension against the arm 1 and thus serving'to fricti-onally hold the arm in any position to which it may be moved around the centerl The outer end of the spring 3'? is bent to a horizontal angle providing a stop for the pawl 35 when in lowered or normal position. If the arm 36 is moved a maximum or plus distance rearwardly (in the direction of the arrow. Fig. 4) the pawl 35 will drop a maximum distance guided by the flange 33, and when the lever 34 is moved in manner explained the pawl will immediately pick up and move the disc 33, thus turning the cylinder 20 a maximum degree, diagonally opposite corners of the notch 35" in the pawl biting the rim of the disc. h/loving the adjusting arm 36 forward to selected distances will res'ult in the pickup occurring correspondingly later following the initial movement of the lever 34, thus decreasing the degree of movement of the cyl- 1 inder 20. The axis oft-he pawl 35 shifts from the support- 37 to the rim 33' and thereafter moves Wiltll' the run. its yoke-shaped end 35 permitting it to shift endwiseon the lever are) prevent any binding other than intended, and for a similar reason the lever 34 is loosely fulcrumed above the center 1 (Fig. 4.). The lever 34 spans the disc 33, thus serving to retain the pawl 35 in proper. position relativeto the disc. With the parts in normal position and the pawl35 stopped against'the end of the wire 37 a slight clearance is providedhetweenthe cornersof the notch and the discrim, permitting the cyl inder to be turned in eitherdirection directmanually, as for the purpose of placing copy thereon, adjusting its position relative to a 7 reading position or guide, or for referring back or ahead in thecopy to verify spelling, etc. i

In Fig. 2 the adjusting arm is designated 36 and is provided with asegment 36" having thereon graduations movable selectively to a pointer 36 for the purpose of predetermining the extent of movement of the cylinder. Thus every time the actuating link 19 is pulled downwardly either manuallyor automatically, the pawl 35 rises with the forward end of the lever 34 and grips the flange 33, turning the disc 33, the tubular shaft 13, the cylinder 20 and the copy clamps to move the copy one or more lines,

or fractions of lines, as determined by the position of the regulating arm 36 in one case or 36 in the form'shown'in Fig. 2.

While it is desirable to limit the width of thelower portion of the supporting frame as much as possible, it is necessary that sufficient room he provided between the upper extensions of the frame to permit the travel 'of the work-paper .(not shown) with the carriage C. To provide the necessary width back of the carriage C, I offset the opposite frame members as at 1 1 thereabove the frame is bent forward as at 1 in order to place the copy at a proper reading distance from the typist. V

In order to protect the paper in the carriage from interference withthe underlying mechanism on the copyholder frame, I provide a rail or track 40 on which the paper travels when it extends beyond the usual apron support 0 of the typewriter. .This

rail is tubular and a spiral spring 40 extends through and supports it,the ends of the This guide can be swung over behind the,

cylindenout of the way, or turned down in front and raised or lowered as desired to place its lower edge at the desired reading position, thus marking the particular line being copied by the operator.v Said bail member 38 is frictionally connected to said rods 1 and 1 as at 38. prefer to make the guide 39 of a transparent material and therefore shadowless, and also for the reason that if the unread copy occasionally advances prematurely under the edge of the guide, it may still be read.

Referring now to Fig. 7, I have shown my device with a modified form of base on which to set a typewriter. This base comprises up to vertical positionsfas at .43, 43", and

connected by [a cross ,rod' e4 The main traineextensions of the device shown inthis embodiment of the invention are designated 1; 1', and are adjustably held in'the erti-' cal .I'neinbe'rs 43?, 43 by ,means of clamp bolts "as shown in: Fig, S'thi' ughQ'the holes45 ofwhich the rods 1{,.f1'f'arei ser pare'nt cylinder holder around which the copy can be placed andheld, together with i an unrestricted; toothless Z ustinent v per- 'mittingmanuscript, letterpress, typewritten,
