This invention relates to copyholders and more particularly to that type of copyholder employed by stenographers and typewriters.

A primary object of the invention is toprovideaholder of this character adapted to be supported adj acentia typewriter in position to display the copy so that it will be always in front of and visible to the operator.

,Another object is to provide improved means for shifting the copy at will and to so display it that a single line will be arranged adjacent the gauge and several lines above and below the gauge may be displayed for the convenience of the operator.

5 Another object isto provide a transparent line guide to enable the operator to locate his place at a glance, and also to view lines already written so that if a mistake should occur, it may be corrected at once.

Another object is to provide improved means for holding the copy in adjusted position without danger of its shifting, and in which position it will remain until manually released. y In carrying out these objects, the inventio is susceptible of a wide range of modification without departing from the spirit or sacrificing any of the advantages of the claimed invention, there being shown in the drawings 3.0 for illustrative purposes a preferred and practical form, in which,

Figure 1 represents a side elevation of a holder constituting this invention shown in relation to a typewriter, which is also shown in side elevation, and in lighter lines than the device constituting the invention,

Fig. 7 is a vertical section taken on'the line 77 of Fig. 6.

In the embodiment illustrated a typewriter 1, ofany make, is shown in side elevation in Fig. 1,"at the rear of which is mounted the holder 10 constituting this invention.

The holder 10 as here shown, comprises sectional supporting standards 11 and 12 connected at their lower ends by a baseplate 13 having forwardly extending arms 14 which are designed to extend under the typewriter 1 as shown in Fig. 1, and, if desired, may be bolted or otherwise fixed'theretozso that the holder will be held in rigid relation in regard to the typewriter, and thereby held against accidental upsetting. These stand ards 11 and 12 are exactly alike, and hence one only will be described in detail. The

sections 15 and 16 of each standard are longitudinally slotted, as shown at 17 and'18 and are arranged in lapping relation with the slots in the sections registering and adapted 7 to receive a wing nut and bolt shown at 19 whereby the sections may be adjusted relatively to each other and secured in adjusted position. This adjustment of the sections, of course, provides for the lengthening or shortening of the standards according to the position it is desired to locate the copyholder proper in relation to'the typewriter.

A cross bar 20 preferably connects the upper ends of the sections 15 as is shown clearly in Fig. 6.

One upper section 15 is provided along its inner edge near its upper end with a forward ly projecting arm 21. This arm 21 is bifurcated at its free end to form bearings 22 and 23 arranged one above the other to receive a pintle 24: which extends through the bear ings 22 and 23 and through a bearing or knuckle 26 of an actuating lever 25, the free 90 end of which is flattened to form a finger grip handle 27.

A lever 30 composed of two laterally spaced arms 31 and 32 carried by a sleeve 33 is fulcrumed on a stub shaft 34; carried by the arm 21. Between the upper ends of the arms 31 and 32 of the lever 30 is pivoted a pawl 35 here shown elbow-shaped in form, and which is designed for a purpose presently to be described. The inner pivoted end of this pawl has a right angularly extending arm 36 having a notch 37 in its free'end and a 'rearwardly extending tooth 38 formed in its rear end at its junction with the body portion of the pawl. The notch 37 formed in the free end of arm 36 providesa'ninclinedstop 39 for engagement with the teeth ofthe ratchet in connection with whichthe pawl is to'be used and limits the throw of-the pawl, as is shown in dotted lines in Fig. 3.

A lug a iO proj ec'ts later-ally rearward "from the 1 arm 32 of the lever #30 as shown clearly in Figs. 3 and 5, and has a set screw 41 with a knurled head i mounted therein, i said head being numbered 42. On the; shank of'the screw- 41' between the head 42 thereo f and the bracket or: lug is mou'nted a cam member 43 including an eccentric inclined shoulder 44: and v a body portion 45 polygonal Eincross se'ction and with" this the tooth of the. pawl 35 is"designedito engage and by means of which the stroke of the pawl is controlled toadapt itsepoint 35 to-en'gage' one, two, or three teeth of theratchet 60, accordingto the :will of the-operator.

'rlr 'plate'46 is mounted on'theouter face of the arm' 32'of lever 30 asshown "clearly in Figs. and '5 with the upper "end extending above said armand provided with a keeper '47 in which is slidably mounted a plate spring 48 attached at one end to P the elbow-- shapedpawl35' at the'elb'ow thereoliand having its other end a provided with a hook 49 designed to engage the k-eeper and limit the stroke of the pawl.

I The secti'ons "15 ofthe standards 1 1 and 12 -are'provided at their upper portions with longitudinally spaced bearingsand 56 to .rece'i've rods 57 and :58 whichoonstitutethe journals of paper rollsor drums 59-and 59 The rods 757-ELI1C158 are 'designedto extend through the 7 standards and .are ,provided at their ends *with knurled knobs 61-to v.pro-

I vide for the turning of the paper rolls by hand and which are removabletofaeilitate the insertion and removal of saidrolls. ratchet gear 60 is fixed to one end of thetrod "57 in positiontobe engaged 'by the pawl 35 by means 'ofwhich'thedrum 59 is rotated to wind from the drum 59- the paper strip 61 -which contains the matter to be copied.

Arranged across thefront "of the holder andsecured to the'front edges of the standard's'ections15 isa' transparent plate 62, preferably ofglas's,which'e'xtends down overthe front of the lower roller 59 and over the space between the two rollers, so that the paper web being fed from one drum to the other will be visible therethrough. A line I be readily corrected.

A link 50 connects the lever 30 with the levefQ'flbymeane ofan arm or lug 51 carried bythe knuckleof said lever and located in a plane at right angles to the lever 25. (See F-ig. 6 This link 50 is preferably made of a metal strip twisted to facilitate its attachr'x'ient to theilevers. :A coiled 'spring'52 connects "the lever 30'with a portion ofthe forwardly projecting arm 21 and i is designed when lever- 25 is releasedfto exert its tension to returnthe p'awl '35 to disengaged position, that is, to lift it "out of contact withfthe ratchet '60, as sho'wn'in :Fig. 7 also in Figs. 1 and-3. 1 7

In the use ofthis holder, it having been connected with'the typewriter 1 asshown in Fig. :1,'the stand'ardsill' and 12 may be adjusted by loosening thewing nuts 19 and movin'g the' sections '15np or down, according to the position inwhich it is desired to locate the holder'proper. These nuts 19 are then tightened up' and the device willbe ready for use "after the paper rolls have 'beenplace'd therein. This is accomplished 'by'removin'g' the knobs (Slat the right of the holder and placing the rolls in position and inserting the pintles or rods 57 and 58 therethrough, then 'replacin'g'theknobs asshown in Fig; 6. The roll 59 containing'the matter to be copied will be fed from said drum or roll to'theroll '59 located abovei't, an'dthis feedi'ng may be accomplished either 'by'turning'the "knobs of the upper roll by hand to wind the web or stri'p'65 onto the'drum 59, or it may be done by means of'the lever-25 which is the quicker way, since all that'is necessary is tounove the lever laterally outward which the operator can quickly defend this will cause'the "pawlf35 to engagethe teeth ofthe ratche-t'GO 'a'nd'rotate the drum one or more teeth according to "the "position of the pawl control 43. When the lever '25 is released, the spring 52'w'ill'expandand retu'rnthe lever 25 ton'ormal position and also carry-the lever 30 back with it. thereby disengaging the pawl from the ratchet wheel ready for'the next 'ope'ration.

While this holder is primarily intended to be used with a -tape or strip on which the dictation ist-aken, obviously,'itmay' be used in connection with a shorthand tablet of ordinary form, which will be placed on the web which is wound on the roller, and which makes a flat surface at the back of the transparent plate 62. This shorthand tablet will be clamped in position at the top and thus allow it to be carried just as the roll paper would be carried but only the length of the tablet sheet.

Without further description, it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will of course be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention or its scope as claimed.
