(Cl. 1Z0-'29) This invention relates `to -copyholders, and more particularly to copyholders of the -type which'may be readily collapsed.

The primary object of the present invention is to provide an 4improved copyholder which -mayf vfor the copyholding member which is jointly cary ried-by the-base andcarrier with interconnecting vmeans permitting the carrier to-be readily moved to its collapsed position.

A still further object of the present invention is to provide a copyholder of the above-type having means for returning the copyholding member Ato ts'normal position on the carrier as the carrier is moved to its collapsed position.

To the above and other ends whichwill-hereinafter appear, the inventionconsists in the features of construction, arrangements of parts, and combinations of devices set forth inlthe following description and particularly pointed out in the appended claims.

The particular copyholder to which the invenftionIhas-been appliedlin thepresentinstance-is 0f the type wherein the copy sheets are-secured toa rcopyholding member and are intermittently .movedlpast a stationary lineindicator. InA this type of4 copyholder, the copyholdingmember-and vlineifndicator are necessarily positionedwhenin vusea considerable distance above the topofan ordinary typewriter, and the usual .foldingcabinet in a typewriter-desk will notr accommodate the copyholding member whenin such raisedv position. Accordingly, the copyholding member andline indicatorare mountedin .the present instance on a carrier which mayfbe movedrelative to the base from araised operative position to a `lowered collapsed position which permits Athe copyholder to behoused along. with a ltypewriter inthe folding Ycab-inet of a typewriter desk.

IThe support or base for the copyholdercomprisesan Llshaped structure formed by va rear base member I0 and .a forwardly extendingfbase vmember II as showninFig-8. When the present copyholder is positioned for'u-sewitha .type- .writing machine, such. as ythe machine Tv shown. in Fig, .1, the rear base member I'U isfdisposed along vthe-rear sideof. the machine and `the forwardly extendingbase member II is fdisposedalong the right .hand side thereof. .This L-shaped base structure for the-copyholder is supported on the same surfaceas the typewriting machinev T by three rubber feet I2 carried by 4the rear base member I0 as shown in Fig. 8 and a similar rub- ;ber foot I3 carried by the' forward end of the' base member I I as shown in Fig. 1.

In order to occupy lessspace when being stored v or shipped, the forwardly extending base member Il .is adapted to be folded against the rear. base Thus, the forwardly extending base member IfI' is pivotally connected to the rear. base member I0 by a bifurcated bracket I5 secured to .the'base member 'I I, whichbracket is connected by a pivotscrew I6 to a bracket Il securedto the rear base member I0 as shown in Figs. 2, 7 and 8.

The basemember II may thus be moved about the axis of the pivot screw I6 to a foldedp'osition against the front side of the base member I0, and when the basemember II is in its forward operative position as shown, the lower'end of --a spring pressed detent plunger I8 (see Fig 2) enters a detent hole provided inthe base member IIJ to resiliently hold the base memberY II in a position extending substantially at right-angle v'tothe base memberv I0.

'Ihe copyholding parts of the present construction are mounted on a carrier which is in turn mounted for movement relative to the base between a lowered collapsed position and a raised operative position as previously pointed out. This carrier comprises a rear sheet metal plate which is mounted for vertical movement on a pair of spaced guide posts 22 which are fixed at their lower end to the rear base member Ill. The carrier plate 20 is provided with lateral extensions 23 at the lower end thereof which are curved to partially embrace their respective posts 22, and associated retaining pieces 24 are secured to the inner surface of the plate 25. These retaining pieces are likewise curved to partially embrace the opposite portions of the posts 22 as shown in Figs. 2 and 7. The carrier plate 20 is thus mounted to move on the guide post 22 between its lowered collapsed position shown in Fig. 1 and its raised operative position shown in Fig, 2.

Releasable latching means are provided for holding the carrier plate 20 in its operative position, and comprise a pair of latches 26 which are pivotally mounted on respective shouldered screws 21 carried by the plate 26. The screws 21 are retained by associated nuts 23 as shown in Fig. 6, and the latches 26 are spaced inwardly from the carrier plate 20 by associated collars 29. Each of the latches 26 is provided with an inwardly extending arm which is pvotally connected to the lower end of a companion oifset link 3D. The upper end of each of the links 3@ is pivotally connected to the inwardly extending end of a companion latch releasing lever 53 pivotally mounted at 34 on the inner surface of the carrier plate 20. Springs 36 exert a downward pressure on each of the links 35 to resiliently hold each of the latches 26 in a position wherein a forwardly extending lug at the lower end of each of the latches engages a shoulder 31 formed by an annular groove at the upper end of each of the guide posts 22.

The latches 26 are thus effective to normally hold the carrier in its raised operative position on the guide posts 22. The outer end of each of the latch releasing levers 33 is providedwith an offset finger piece 40 shown more particularly in Fig. 6, and the carrier may be readily moved to its lower position by pressing downwardly on each of the finger pieces 4D to move the lower end of the latches 26 clear of the shoulders 31 against the force of the spring 35. In order to facilitate the raising and lowering of the carrier, a pair of arms 42 are fixedly secured at 43 to the carrier plate 20. These arms i2 are positioned directly beneath the respective latch releasing levers 33, and the arms 42 are provided with respective offset nger pieces 44 which are generally the same shape as the finger pieces 46 but reversely disposed. When the carrier is raised to its operative position with the aid of the arms 42, the lower ends of the latches 26 slide along the insides of the guide posts 22 and move outwardly under the force of the springs 36 when the carrier reaches its fully raised position to retain such position by engagement with the shoulders 31. A stop arm 46 is secured by a companion screw 41 at the upper end of each of lthe guide posts 22, and these stop arms are engaged by the nuts 23 to limit the upper movement of the carrier.

The top and bottom edges of the carrier plate 20 are bent forward to form flanges as shown in Figs. 3 and 4, and a front cover plate 50 is pro- 75 vided with rearwardly extending top and bottom flanges which overlap these forwardly extending top and bottom portions of the rear carrier plate 26. A pair of vertical guide rods 52 are mounted in spaced parallel relation between the rear carrier plate 29 and the cover plate 5, and screws 53 pass through openings in the top and bottom flanges of the plate 20 and cover 5U, which screws are threaded into the ends of the guide rods 52 to hold these parts of the carrier in their assembled relation.

In the present copyholder, the copy sheets are moved with relation to a line finder or indicator mounted on the carrier as previously described. However, from the broader aspects of the present invention, it is to be understood that the copy sheets could be mounted stationary on the carrier and the line indicator could be arranged to be moved with relation thereto.

The specific form of line indicator shown in the present drawings comprises a horizontally disposed strip 55 shown particularly in Figs. 1, 3 and 4. The strip 55 is shown as being of sheet metal, but it may be found preferable to use a semi-transparent or translucent material such as colored Celluloid. The lower edge of the strip 55 is suitably attached to a horizontally disposed bail rod 56 and in the present instance, the lower edge of the strip 55 is benl-I around the rod 56 in a manner to permit the strip 55 to be adjustably turned about the rod but to grip the rod with suflcient tension to retain its adjusted position thereon. The ends of the bail rod 56 are bent downward and then inward as shown in Figs. 1 and 2. The inwardly extending ends of the rod 55 are frictionally retained in sockets formed in brackets 51 by clamping members 56 secured to the respective brackets by screws 59. The brackets 51 are secured at 66 to the inside surface of the carrier plate 26. The screws 59 are adjusted to grip the lower ends of the rod 56 with sufcient tension to allow the bail rod to be adjusted to obtain the desired position of the line indicator and to frictionally hold it in the adjusted position.

The means for advancing the copy sheet past the line indicating strip 55 is shown in the accompanying drawings as a copyholding member 65 mounted for bodily movement relative to the carrier. However, it is to be understood that from the broader aspects of the present invention, other well known means may be employed for moving the copy sheet with relation to the carrier and line indicator. For example, a roller feeding mechanism of various types well known in the art could be employed for this purpose.

The copyholding member 65 in the present in- .stance is in the form of a rectangular sheet metal plate which is reinforced by rearwardly bent flanged portions around its edges. The copyholding plate 65 is mounted for vertical movement on the guide rods 52 by a bracket 66 secured to its rear surface at the lower end portion thereof. Referring to Figs. 3 and 4, it may be seen that each end of the bracket 66 is provided with two rearwardly extending ear portions in vertically spaced relation. These ear portions of the bracket 66 are provided with eyelets 61 which receive the guide rods 52, whereby the copyholding plate 65 is mounted to move freely along the vertical guide rods. As may be seen in Figs. 2, 4, 6 and '1, the inwardly extending ears on the brackets 56 pass through the respective vertically disposed slots 68 in the carrier cover plate 50 to permit the copyholding member 65 to move vertically with relation to the carrier. In order to maintain free movement of the eyelets 61 along the guide rods 52, a collar 69 of felt or like material may be provided on each of the guide rods, which collar may be saturated with a lubricant and arranged to slide on the rods to lubricate and clean the guide rods. Y

The means for retaining copy sheets on the front face of the copyholding plate 65 may be of substantially the same construction as shown in PatentNo. 1,719,422 granted July 2, 1929. Referring particularly to Figs. 1, 2 and 4, it maybe seen that this construction includes a bail 15 extending horizontally across the ltop portion of the copyholding plate 65, and the inwardly extending ends of this bail are received in slots provided in opposite end portions of a bracket 16 extending along the upper edge portion of the plate 65. An arm 18 is secured in a channel in each end of the bail 15, and springs 19 are provided between each of the arms 18 vand the top portion of the bracket 16 to normally ,press the topY of the bail inwardly toward the copyholding plate. A plurality of rubber rings 8 are arranged on the horizontal portion of the bail 15. Thus, a copy sheet, or stenographers note book may be placed beneath the rubber rings 80 and securely clamped against the plate 65 by the force of the springs 19. When it is desired to insert or remove material to be copied, the bail 'l5 may be swung forward to a position wherein the arms 18 engage the rear surface of the bracket 16 and the lower ends of the springs 19 are thus moved across the pivotal axis of the bail 15 to retain the bail in this forward released position.

Means are also provided for holding transcribed copy sheets in a turned position over top of the copy carrying plate 65. This means in the present instance is shown as a spiral contractile spring 82 extending across the top of the horizontal portion of the bracket 16. The ends of the spring 92 are attached to the respective end por-- tions of the bracket 16, and the spring is provided with a certain amount of tension so that sheets after they are copied may be placed beneath the spring to be held thereby in a turned position over the top of the copy carrying member 65.

The means for controlling the upward and downward movement of the copy carrying plate 65 with relation to the carrier includes mechanism carried in part by the carrier and in part by the stationary basey members. The portion of this mechanism carried by the stationary base members includes a forwardly extending lever 85 which is pivotally mounted at 86 to an upstanding portion of the forwardly extending base member as shown in Figs. 1 and 2. A handle 88 is mounted at the forward end of the lever 85, and this handle may be adjusted along the lever 85 to the desired position with relation to a typewriting machine T. The adjusted position of the handle 88 on the lever 85 may be retained by tightening a clamping screw 89 provided on the handle.

The rear portion of the lever 85 is bent inward and is provided with a reduced semi-circular end forming a ball and socket type connection with a bifurcated member 92 carried by the end of an arm 93. The arm 93 is pivotally mounted at 94 to an upstanding portion on the rear base member I as shown in Fig. 2. It will be noted thatJ the ball and socket connection between the lever 85 and the arm 93 is normally positioned directly above the pivot screw |6 connecting the twol base members` l0 and H; Accordingly, the Ylever merely pivots about its connection with the arm 93 when the forwardly extending base member I is folded against the rear base meme ber |0.

The portion of the mechanism for controlling the upwardA and downward movement of the copi/holding member which is mounted on the carrier may be generally similar to that disclosed in Patent No. 1,837,027 issued December 15, 1931. This mechanism includes a lifting rod 91 fixedly secured at 98 to the upper bracket member 16 on the copyholding plate 65, and the lower end of the rod 91 is retained against displacement laterally by an extension 99 on the lower guide bracket 66 at the bottom of the copyholding plate. The extension 99 passes through an elongated vertical slot |0| in the carrier cover plate 50 and the upper end of the rod 91 passes through an opening'in the top flange portion of the rear carrier plate 20.

The upward and downward movement of the copyholding plate is effected through a control rod |03 `mounted for longitudinal movement on the carrier. The upper end of the control rod |03 passes through an opening in the top ilange of the carrier plate 20, and the lower end of the control rod is retained against lateral displacement by a guide bracket |04 secured to the carrier plate 20 to partially embrace the rod |03 as shown in Fig, 5. In order to provide a substantially noiseless and frictionless guide for the upper ends of the rods 91 and |03, a liber plate |05 is secured to the lower surface cf the ange at the upper end of the carrier plate 20 as shown in Figs. 2, 3 and 5. This ber plate is provided with bearing openings receiving each of the rods 91 and |03, and the metal of the carrier plate ilange is cut away around these bearing openings to be out of contact with the rods.

The control rod |03 is moved either upward or downward from its illustrated position to control movements of the copyholding plate 65, and for this purpose an interconnecting means is provided in the form of a link ||0 pivotally connected at to the intermediate portion of the arm 93 on the base member I0, and the upper end of the link is operatively connected to the lower end of the rod |03 when the carrier is in its raised operative position. Referring to Figs. 2 and '7, it may be seen that the connection between the upper end of the link ||0 and the rod |03 comprises a clip ||4 attached by a screw ||5 to the lower end of the rod, and the clip carries a shouldered screw ||6 threaded into an enlarged retaining washer ||1. 'I'he intermediate portion of the screw ||6 passes through an elongated slot ||8 extending substantially the entire length of the link ||0, and the upper Vend of the slot ||8 extends laterally toward the rod |93 to provide shouldered portions disposed above andbelow the body of the screw 6 when the carrier is in its raised operative position as shown in Fig. 2 for example. A leaf spring member |20 is secured by the screw I5 in a position to resiliently hold the upper end of the link I0 in a position wherein the shoulders formed by the upper end of the slot ||8 are disposed above and below the screw |6 and thereby operatively connect the lever 93 with the control rod |03.

It will now be clear that a manual depression of the handle 88 will cause an upward movement of the control rod |03 through the arm 93 and link ||0. This upward movement of the rod |03 istransmitted to the copyholder rod 91 through a lifting clutch member |25 which is formed of a rigid piece -of channel-shaped metal having a slotted end portion which straddles the control rod |03 as shown in Fig. 6. A pin |26 is carried by the rod |03 directly beneath the lifting clutch member |25, and a retaining pin |21 is also carried by the rod just above the clutch member |25.

The copyholder rod 91 extends througha rectangular aperture in the lifting clutch member |25, and clutch jaws |30 are mounted in this rectangular aperture to engage opposite sides of the rod 91 Each of the jaws |30 comprisesametal casing having a non-metallic lining or filler of the type specifically disclosed in Patent No. 1,837,027. Thus, when the control rod |03 is moved upward by a depression of the handle 88, the lifting clutch member |25 receives a slight angular movement caus-ing the clutch jaws |30 to grip the copyholder rod 91 so that the copyholding plate 65 is moved upward by the continued upward movement of the rod |03.

This upward movement of the copyholding plate 65 moves the copy sheet past the line indicator 55, and in vorder that this movement may be adjusted to accord with dierent extents of line spacing on various copy sheets, an adjustable stop is provided Vfor limiting the operation of the lever 85. Referring to Figs. 1, 2, and 8, it may be seen that this adjustable stop is mounted on a bracket |34 secured to the rear portion of the base member Il. The bracket |34 extends upward 'at the side of the rearward end of the lever 85, and a stop member |35 is mounted for vertical adjustment on the bracket' |34. The upper end of the stop member |35 is bent inward and is provided with a cushioned stop contact |36 which is positioned to be engaged by the rearward end of the lever Y85 when the handle 88 is moved downward. The desired position of adjustment of the stop member |35 may be retained by a clamping'screw |31 which passes through a vertically disposed slot in the bracket |34 and is threaded into the stop member |35. Thus, the position of the stop member |35 may be adjusted to aiord an extent of movement of the lever 85 which will result in the desired extent of line spacing movement of the copysheet with respect to the line nder 55.

A' returning spring |40 is provided between the arm 93 and the rear base member I0 as shown in Fig. 2. This spring acts to return the lever 85, armr93 and rod |03 to their normal'positions when the downward pressure on the handle 88 is removed. During this downward return movement of the rod |03, the end of the lifting clutch member |25which is connected to the rod |03 is moved downward toward' a straightened position which releases the clamping engagement of the clutch jaws '|30 with the copyholder rod 91. Thus, the return downward movement of the rod |03 does'not cause Va corresponding downward movement of the copyholding member through the rod 91.

A releasable 'holding clutch mechanism is provided'for normally retaining the copyholder in the position to which itis raised through the liftingclutch memberv |25. This holding mechanism com-prises a vholding clutch member '|42 which is generally similar to the lifting clutch member 25. One end of the member1|42 is bifurcated to straddle` the control rod-|03 inthe same manner as the member |25 and the other end `is likewise provided -with a rectangular shaped apertureinwhich-apair ofl clutch jaws Vrod '91.

extendingiportion of a bracket |45 which is secured at |46 to the carrier plate 20. A contractile spring |41 extends between the bracket |45 and the intermediate portion of the clutch-member |42 to normally hold it in a position wherein the clutch jawsv |43 'are in clamping engagement with the rod 91 to preventvdownward movement thereof. However, when the rod 91 is moved upward through the lifting clutch member |25, the clutch member |42 receives a slight pivotal movement about the bracket |45 until the clutch jaws |43 do not effectively engage the rod 91 and thus permit the rod 91 to move upward relative thereto. When the upward force on the rod 91 is removed, the tendency of the copyholder to move downward causes the clutch jaws |43 to again engage and hold the rod4 91.

When it is desired to lower the copyholding plate 65 on the carrier, the handle B8 may be raised from its normal position to pull downward on the clutch control rod |03. This downward movement of the rod |03 causes the pin |26 to engage the holding clutch member |42 and move it toward a horizontal position against the force of the spring |41. This movement of the member |42 releases the normal gripping engagement of the clutch jaws |43 with the rod 91 thereby permitting the copyholding plate 65 to move downward by gravity to its normal or first-line copying position with respect to the carrier.

A retarding mechanism is provided in the present copyholder in order to prevent the copyholding p1ate'65 from gaining undue momentum in its downward movement. This retarding means in the present instance comprises a retarding clutch member |5| having clutch jaws |52 carried thereby inA contact with opposite sides of the rod'91. lOne'end of the retarding member |5| is mounted at |53 to the lower side of the top angeportion of'the carrier plate 20, and the other end of the member |5| carries a threaded rod |54 extending upward through an aperture in the flange of'the carrier plate. An expansion spring |55 is provided on the threaded rod |54 between the retarding member |5| and the flange of the-carrier plate 20 and a knurled adjusting nut4 |56 is threaded on the upper end of the rod 54- to normally engage the upper surface of this carrier plate ilange The slight angular disposition of the member |5| causes a slight gripping action Ibetweenvthe jaws 52 and the rod 91 to retard thedownward movement of the copyholding plate L65, and the extent of this retarding action may bevaried by turning the nut |56 in one direction'or the other to accordingly vary the angular disposition of the member 5|.

vThe copyholding plate 65 with the copy sheets or other' transcribing. material attached thereto is thus retarded in a downward movement to normal position on the carrier, and shock ab sorbing means are provided to arrest the copy carrying plate in its normal position with a minimum of noise-and shock. Thus as may be seen in. Figs. 2 and 4, a coiled expansion spring |58 is placed around the bottom portion of each of the.` guide rods 52. The lower ends of these springs 58' rest on the lower ange of the carrier plate 20, and as the copyholdng plate 65 reaches its lowermost normalposition, the upper ends of the springs |58 are engaged by the lower portion of the bracket 66 on the copyholding plate as shown in'Fig. 4 to resiliently arrest the downward movement of the copyholding plate with a minimum of noise and shock. l

It will now be understood that when the carrier is in its raised operative position on the guide posts 22, the copy carrying plate 65 may be moved relative thereto intermittently in an upward direction by depressing the handle 88 and may beA returned downward to its normal position by lifting the handle. In order to control this movement of the copyholding plate on the carrier, the connecting link IIO has been arranged to transmit both upward and downward movement from the arm 93 to the rod |03 when the carrier is in its raised operative position. Accordingly, the operative connection between the link I and the rod |03 must be interrupted when it is desired to move the carrier to' its lowered collapsed position with relation to the base. In accordance with the present invention, means are provided for automatically interrupting this operative connection between the link IIIJ'and the rod |03 when the latch members 26 are operated to a released position enabling the carrier to be lowered to its collapsed position. Referring to Figs. 2 and 7, a slide |64 lis mounted for horizontal movement on the inner 4side of the carrier plate 20 by headed rivets |65 passing through respective slots in the slide |64. One end of the slide |64 is bent laterally to coact with the edge of the link I I0 but is normally heldl out of contact therewith by a contractile spring I 66 extending between the slide |64 and a pin |61 secured to the carrier plate 20. The outer portion of the slide |64 extends vupward and Vis provided with a laterally bent end whichnormally engagesthe edge of the lower portion of the left-hand releasable latch member 26. Thus, when the latch members 26 are moved inward out of engagement with the shoulders 31 ofthe guide posts 22 by depressing the linger pieces 40 of the latch releasing levers, the left hand latch 26 moves the slide |64 horizontally to engage the edge ofthe link I'IIJ and causes a movement of the upper end of the link toward the rod |03 against the force ofthe spring |20. This movement of .the upper end of the link IIO positions the vertical portion of the slot II8 beneath the body portion of the connecting screw I6 so that the carrier'may be moved downward along the guide post 22 with the screw vI I6 moving in the vertical portion of the slot II8.

In this manner, the link |I0 which normallyconnects the arm 93 with the rod |03 for movement in either direction when the carrier -is in its raised operative position is automatically disconnected by operation of the releasablev latch mechanism to permit the carrier to be readily lowered to its collapsed position. When it is desired to again raise the carrier to its operative position, the screw I I6 slides in the slot I|8 until the carrier is latched in its operative position, whereupon the spring I 20 moves the upper end of the link IIO back to its illustrated position which operatively connects the arm 93 and rod In order to place the present copyholder in its fully collapsed condition, it is not only necessary to move the carrier downward with relation to the base, but it is also necessary to have the copyholding member in its normal position withrelation to the carrier. Accordingly, means are provided in accordance with the present invention for automatically returning the copyholding member to its normal or lowermost position with relation to the carrier when the carrier is released for movement to its collapsed position with relation to the base.

Referring to Figs. 2 and 6 a lever |10 is pivotally mounted at its central portion on the inner surface of the carrier plate 20 by a headed rivet I1I. One end of this lever |10 is bent laterally to normally engage the upper edge of the inner end portion of the right-hand latch releasing lever 33. The other end of the lever |10 is also bent laterally to extend above the bifurcated end of the holding clutch member' |42. Thus, when the latches 26 are released to permit downward movement of the carrier to its collapsed position, the lever |10 is rocked about its pivot by the releasing movement of the right-hand latch releasing lever tothereby move the holding clutch member I 42 toward its horizontal position. This movement of the member |42 releases the clamping engagement of the jaws |43 with' the rod 91 and permits the copyholding plate to move downward to its normal position 'as previously described.

The present collapsible copyholder may if desired be secured permanently in the usual manner to the supporting surface of a folding cabinet of a typewriter desk. However, means are provided which cooperate with a typewriting ma-l chine, such as T shown in Fig. 1, to releasably retain the copyholderin position against accidental displacement, thereby making it unnecessary to `permanently secure the copyholder to the supporting surface.

` The means shown in the present instance for retaining the forwardly extending base member I I is fully disclosed in Patent No. 2,155,246 issued April 18, 1939. This retaining means may be generally described as comprising a carrier |15 mounted for vertical movement in a slot |16 in the base member II. ing arm |18 is pivotally mounted on the carrier |15 for movement between its position shown in Fig. 8 and a collapsed position against the inside surface of the base member II. Spring means, not shown in the present drawings, are provided to act upward on the carrier |15 and to hold'the.

arm |18 in engagement with the lower edge of the typewriter side plate. The carrier |15 is so arranged that any force tending to raise the base member II from its supported surface is resisted by the engagement of the arm |18 with the typewriting' machine to cause a binding action between the carrier and the base member,` I I. This retainingk means may be readily released by a downward pressure on the carrier member |15, and it is arranged to cooperate equally well with different typewriting machines regardless of thel distance between the lower edge of the side plate and the supporting surface.

Means are also provided for retaining the lefthand rear portion of the copyholder against displacement with relation to the typewriting machine. This retaining means may if desired, be the same as that provided on the base member II, but in the present instance a specically different means has been shown. Referring to Figs. 2 and 8, it may be seen that a rubber covered retaining'arm |80 is mounted on an adjustable slide member ISI for pivotal movement thereon between a forwardly extending position as shown and a folded position along the base member I0. The slide |8I is mounted for vertical adjustment along an upward extension |82 on the base 'member It, and the arm lso is normally positioned in A rubber covered retain- Animproved-copyholder has thusbeen pro-- videcljwhioh' is comparatively simple and inexpensive tomanufaoture and yetv highly effective and reliable in use. A particular feature of the present copyholder is the arrangement of the copyholding member on a carrier which may be movedwith relation to its base between a raised operativev position4 and a lowered collapsed position: This feature involves'the provision of improvedmech'anismfor controlling the movements ofthecopyholding member. with relation to the carrier, which mechanism isjointly carried by the base` .andthe carrier withinterconnecting means arranged. to` automatically establish an operative connection between the controllingmechanism on the baseand'thecontrolling mechanism on thesoarrier. whenithe carrier reaches its raised operative position and' having means for automatically interrupting this operative connection'when the. carrier; is released for movement to itslowered'` collapsed. position..

Another feature of the present copyholder is the provision'oi mea-nsfor automatically returning'fthe'copyholding member to -itsnormal posi'- tioncwith relation to the carrier as, thev carrier is moved Fto itscollapsed position; TheseVV features cooperate'to provide a. copyholder which ymay be easily and `quickly changed lfroma condition affording normal operation to a collapsed condition permitting vit to be housed together with a typewriting machine'in the' folding compartment of aV typewriter desk.
