"Figureis aview somewhat similar to'Figure `l but showing theline guide latching mechanism in copy an unlatched .position ininterengagement with limiting 'myself to theparticular -form of copy holder illustrated therein. l

As herein shown, the-copy holder includes a base I0 having'an'arm I l extending 'from one end thereof. Thearm H is shown as being in the form of 'an angle iron in cross section, and

'may be secured 'toa desk or tableto hold the copy holder upright. The arm l'l Yalso forms a pivotal support foran l'operating link and lever mechanism indicated generally by 'reference cthara'cter l2, for rotating a'platen 14. 'step by s ep.

holder frame I5, mounted on said base for vertical extensible movement with respect thereto. The link and lever mechanism I2 and the mechanism actuated thereby for rotatably moving the platen a line at a time is shown and described in my Patent No. 2,170,161, dated August 22, 1939, and is no part of my present invention, so need not be shown or described in detail herein.

The copy holder frame I5 is shown as being slidablyv mounted on two upright rods I1-I1 suitably secured to the base I0 at their lower ends and extending upwardly therefrom in parallel relation with respect to each other. The

upright rods II--II each have slidable engagement with two parallel, vertically spaced lugs I3 and extending forwardly from a back 2| of the copy holder frame I5. A rib 23 connects the lugs 20-20 together and serves to stiften the copy holder frame I5 and also serves as abutment means for springmeans for moving and holding the copy holder latching mechanism into an unlatched position, as will hereinafter more clearly appear as this specification proceeds.

The platen I4 is suitably mounted on a shaft 24, for rotation therewith. The shaft 24 is journaled at its ends in side frame members 25-25 of the copy holder frame I5. Said shaft extends outwardly from said side frame members and has knobs 21-21 on its outer ends, to permit turning of the platen by hand independently of the lever operated actuating mechanism therefor, when desired. Y Y

A line guide member 29 is spaced forwardly of the copy holder frame I5 and is mounted for extensible orv collapsible movement with respect to the base I0 with the copy holder frame I5. The line guide member 29 -is herein shown as including a cross head-3D having twospaced hollow rods or sleeves 3I`3 I depending therefrom, adjacent opposite ends thereof, in parallel spaced relation with respect to each other. The sleeves 3'I-3I are slidably mounted on parallel spaced rods 33--33 suitably mounted in the base I0 at their lower ends for yieldable movement with respect thereto, and biased to engage a pressure roll 34 with the platen I4. The pressure roll 34 is herein shown as being rotatably mounted on ears 35-35 extending inwardly from the cross head 30, and exerts pressure on the paper to hold the paper to the platen I4 sothe paper may be positively advanced a line at a time, upon progressive turning movement of said platen.

Referring now in particular to the novel form of the cross head 30, wherein said cross head maintains a sheet of paper in, position so it may easily be read when the paperlias been released from' the pressure roll 35, the cross head 30 is herein shown as having anl inwardly turned upper end portion or lip 40. VThe lip 40 is herein shown as extending at right angles to the body of the cross head and engages the lower edge of the paper when released from the pressure roller 34 and supported on

copy guides

35 and 31 and trained under an intermediate copy guide 38, as may be 'seen in dotted linesin `Figure 9. The lip 40 of the cross head 30 thus projects partially over the pressure roll 34 and holds the lower edge of the paper from moving upwardly into such a'position that the material thereon cannot readily be seen. This remedies an objectionable feature of former copy holders in which it is impossible to read notes or insertions at the bottom ofthe paper without removing the paper from the copy holder and placing it flat on the desk. `While the lip 40 is herein shown as being turned at right angles with respect to the body of the cross head, said lip need not extend at right angles with respect to the body of the cross head, but may extend at various other desired angles or may be of a uniformly curved formation, as long as its lower edge may come into gripping engagement with the lower edge of the paper when released from the platen 24.

The

copyvguides

31 and 38 are mounted on parallel spaced pivoted arms 4 I-,4I, secured to a transverse shaft 43, having the c01357 guide 36 secured thereto. The shaft 43 is shown as extending beyond the limits of the copy holder frame I5 to guide paper wider than said frame, and a free open space is provided between the Vline guide member and the platen I4 to permit the insertion of sheets of paper therebetween, wider than the length of the copy holder frame I5.

The copy guide 35 is herein shown as being securedto the transverse shaft 43,l for turning movement therewith and is restrained from movement by the legs 4444 .of a U-shap'ed spring 45. Thelegs 44444 engage opposite sides of the copy guide 36 and restrain the arms 4'I-4I and

copy guides

31 and 38 from movement, and yieldably hold said arms and the copy guides carried thereby in the upwardly extended position n shown in Figures 3 and 9.

A means is provided to hold the line guidemeinber and pressure roll 34 out of engagement with the platen I4 and to align the paper with the cross head 29. Said means,` as shown, includes two spaced arms 46-46 secured to and extending from a rod 41. The rod 41 is journaled adjacent its ends in the side frame members 25-25 of the copy holder frame I5. A torsion spring 49 encircles the rod 4.1. One end of said spring is secured to the rod 41, and the opposite end thereof engages the top surface of the lug I9 and urges the rod 41 to move in a direction to hold the lever arms 46--46 in a downwardly extended position out o f engagement with the sleeves 3 I 3I of the line guide Vmember 29. `When the arms 45-48 are turned outwardly, by grasping .with the hand, to the position shown in Figure 3, the line guide 29 and pressure roller 34 are moved away from the copy holder frame l5 and platen I4 in an obvious manner. The strength of the spring 49 is such that the arms 46-46 were retained in the outwardly extending position shown in Figure 3 by the friction between the ends of said arms and the sleeves 3I-3I,V and said arms are only moved in the downwardly extended position shown in Figure 4 by the spring 49, when positively released from the sleeves 3I-3I by hand.

It may here be seen that when the arms 46-46 are in the horizontally extended position shown in Figure 3, moving the pressure roll away from the platen I4, said arms not only form a means for readily inserting the paper in the copy holder, but also form an accurate aligning means, bottoming and aligning the sheet of paper being copied.

Referring now to the novel latching and release means of my invention, for latching and releasing the copy holder frame I5 and line guide 29, a Vdetent rod is provided to lock the copy holder frame in an extended position. The detent rod 58 is pivotally mounted in the side frame members 25-25 Vand isvurged by a torsion spring 5I to pivot in a direction to come into engagement with recessed portions 52-52 of the support and guide rods I1-I1. The spring 5I encircles the detent rod 53 and is secured thereto at one of its L ends. A-The other-endofsaid-;spring engages the ribV 23:.and urges the detent vrod to .pivot .in ya countercloclrwise direction. VA winged iinger grip 53 :is shown .as lloeingvsecured to the outer end, of said-detent rod, for turning said; detentrrod againstsaid .spring .into a released position. The detent rod 5I), Aasrherein 'shown,fhas-two .recessed portions formed therein in registry with the guide rod .Ilo-I1, the -inner sides of which are-ilat, as indicated by reference character 54. The flat inner sides-54-54of the detent. rod'are in alignment with thejouterperipheryof thefsupport and guide rods -I 'If- I 'I when -saidV flat sides are in a vertical position; Thus, when the detent rod 50 is turned in a position bythe fingeligrip 53 to position thelat sides-5ll- 5ll thereof :in .alignment withthe peripheryof :thelsupportfandfguide ro'dsII'-I-'I, the Copyholderoframe I5 may freely move along` said rodl into 1a lcollapsed position.

` While fthe rod -50 -is-` shown'as having two frecessed portions, -it should be-understoo d that the entire rod may be'flattened along'` its length, if desired.

Asthe.copyholderfframe. I5 is extended along thesupportand'guide rodsrl 'I-I 'I and the detent rod. 5 5 comes intol registry ywithfthe recesses 524-52,y the torsionsprng 5I will; rapidly turn said detentrod to engage Aftheperiphery-thereof with the recessed portions52-52 yof -the lsupport and guide rods` Ill-I1, locking the copyL holder frame I5 in the upwardly extended-position shown in Figures -2A and 3. i .A self-operating means has thus .been provided to automatically lock, the copy holder Aframe in the desiredpositionY of extension with no attention fromthe operator who may be extending the copy holder.

. rIhe means for .lock'ng thelineguide memberv 29 in upwardly extended relationshipwith respect tothe base I0, 4inifthetproper alignment with respectyto the plat-en- I4-, includes 'af-separate spring.A pressed -pin '55 slidably mounted in each od.33, 'adjacent the upper end thereof. Thepins 55-55 arez'spring urged into engagement with one or the other of apair of aligned inclined slotted portions Elie-56,. formed in :opposite sides of each sleeveqBI. k,The pins 155-55. may rbe urged into engagement v.with the inclined slotted portions 58-56 bygrneansof an elongated springwire 58, secured tonsaid pinV and extending upwardly `through a! drilled portion of

therod

3,3 and abutting an edgethereoij'and so inclined with respect to saiddrilledportion ofsaid rod asto continually urge .the pin r55outwa1dly,with respect thereto. Thus, when; the yline guide` member 29 is moved into Athe-upwardly extended Position shown in Figures Zand 3, the vpins 55-55 will beurged into registry with the respective slots SG'f-SS-and-hold said lline guide in an upwardly extended posi- Q fthelnger grip'53." Eachrockingarm 571, as herein ffshown, extends inwardly from the rod I59; towardl the backA 2| of the yframe I5 anddown-'- wardlyalong-the h aclr,.of said frame andv has a; forwardly-extendedbifurcated foot 6l the f urcations cof-,which are-adapted to register with thel 6j inclined lslots 56-7-56., ori-.opposite ,sidesvofzthe sleeves 3 I-3 I. The inner edges ofthe furcations of the feetBI-fl are evenlycurved to engage the edge ofthe pin and move said-pin inwardly with .respect tothe -rod 3.3k into positiongwhere it .may clear the slot 55 Yas shown in 'Figurey permitting the sleeve Y3'I toy telescopically move with respect to the rodr33v. Whenthe feet 6 I -6`I are in position to release the pins 55---55,V engagement thereof with the'slots 56--56 will positively move line guidememberil withl the copy holder frame I5, upon movementvof said copy holder frame. Y y f v; if The downwardly turned Aend portion G'of ythe rod k5,9 :engagesfa pin 62 'secured to and extending inwardly from the winged .ringer` grip 53. A tor# sion springiIS encircles the rod andfissecured thereto atoneofits ends,` while the opposite end thereof may have abutting engagement with the copy holder'irame'iIE, as with the-rib23: .Said spring urges the downturned end'ofthezrodfS into engagement withl the ypin .621;and isstrong enough to release thebifurcated feet 6I-5 I V'from the slots Sli-56, upon movement of the .detent rod 50 into engagement with the recessed; portions 52-52 of the rods I'I-Iz'I. i a

When the copy holder frame I5 is inthe uppermost position of adjustment shownin 'Figures' 3, 4 andv 5, with ther'detent rod 5.9 "positively engaging theA recessed .portions-52752. of the .support and guide `rod tlf-Il, the Lpins 55;-55xf-Wi1l engagethe slots 56,-.-56lofthe sleeves i3 I--L'3I,.a'nd the copy holder framerl andiinei guide member- 29 will be heldin alignedupwardly extended1relation with respect to eachother, with .the pressure roller -3Agin kposition to engage theplateni. When it is desired tel release the copyholder frame I5, the wngednger gripg5-3 and detentrlod 50 may be turned ina direction, which in Figures 4 and 5 is shown as vbeing a Lcounterclockwise direction, until the at surfaces 54-54 .of the detent rod50 come into registrygwith'the outerV periphery of the 'support and guide;rods.Il'-I,'I, at which time the copy holderfi'rame 1I5'rmayslidably move downwardly =along the :support vandr guide 'rod Ilr-I L theI flat, portions .of zthe detent rod 50 sliding along the outer side of saidsupportand guide members. Turning of the wingediinger grip 53 in they countercloclrwise directionY just mentioned, will also turn the rockingtarms.4 51--551 in the samedirection'by engagement ofzthe pin 62 with thedownturnedend 6.8 of J the/.rod 259.: This-will move the lever armsp.5'I.-51 and feet Eil-6I from the positionfshown-,insolid linesgin Figure 4 to thedotted position' in thisgure into: registry with the slots'55j-56vand intengagement with the pins 55%55, moving :said pins .tofthel released positions shown in Figure' 8. Downward pressure on the/copy holder frame vI5'zwill thenv slidably move saidfpin downwardly'along the supiport and guide rods Ile-I1, and atthe same timev will telescope the line guide memberzZa by en#-y gagement of the feet 6I-6I with the slots 564-56,

When itis desired toextend` the ,copy holder,

upwardpressure may be exerted'thereon'loyxgrip.l

ping with the hand and the entirecopy' holder frame I5 may be moved'upwardly along the/sup port and guide rods -I-'i--I I until thedetentfrodn comes into registry with the recessed portions. 5 2 -5 2 ofvsaid support and guide grods. At this time the spring 5 I will pivot the `rod 50 andmovethe circumferential portion thereofinto Aengagement withthe recessed portions 52-52, positively' locking the copy holder -frame.I5.in'its.elevatedposition along the;support;andfguidebars$11441;

giriamo At the same time, the torsion spring' 63 will cause the downwardly turned end 60 of the rod 59', to follow the pin 52 and move fthe bifurcated end portions of the `feet 6`I-6 out of engagement with the slots 56-56, allowing the pins 55-55 to come into engagement with said slots and locking theline guide member 29 in the proper relationship with respect to the platen I4.

It should here be understood that the torsion springs I and y63 are both relatively strong springs and that the spring 5| snapsthedetent rod 50 into engagement with recessed portions 52-52 as soon as said rod vcomes into registry therewith.v The spring 63 is likewise strong enough'to aid 'pivotal movement of the detent rod 50 into engagement with the recesses 52-52 and 4cause release of the bifurcated portions'of the feet 6l'-6I from the slots 56-56 with a snap action, ysimultaneous with engagementv of the circumferential portion of the detent bar 50 with the recesses 52-52.

It will be understood that modifications and variations may be effected without departing from the spirit and scope of the novel concepts of the present invention.
