20 Claims.

My invention relates to copy holders and the objects of the invention, generallyv stated, are as' follows;

To provide a highly effective and easily manipulated copy holder for indicating the lines successively line-at-a-tixne as they are being copied. To provide simple and eicient means for intermittently .and substantially noiselessly feeding the Copy line-at-a-time and in which the extent of each line space intermittent feed may be varied at will. 1

To provide highly effective means that are simple and reliable in their operation for readily returning the work sheet carrier to its initial position with'but little or no noise from any position to which the work sheet carrier may have been intermittently fed.

To provide improved means whereby a plurality of overlapping copy holder members may be readily expanded to theirfullest height during the feed of the copy, or may be readily collapsed to the first line indicating position.

To provide a construction of the .character hereinbefore set forth with means whereby the copy holder may be further collapsed from its first writing line position to a position of nonuse where it may be moved into a drop cabinet of a typewriting machine with said machine and without interfering with the movement ofthe machine into and out of the cabinet.

To the above and other ends which will hereinafter appear my invention consists in the features of construction, arrangements of parts and combination of devices set forth in the following description and particularly pointed out in the appended claims.

The present invention is in the -nature of an improvement on the construction disclosed in a companion application led March 24, 1933, and bearing Serial No. 662,484. Features common to the two constructions are claimed in-my said companion application, the claims herein being directed to features not disclosed in vsaid companion application.

Generally stated the present construction involves a plurality of `overlapping members that may be intermittently and noiselessly relatively fed to an expansible position represented in dotted lines 2, and may at will be readily and noiselessly returned to the first line indicating position represented by the height of theY rst section as shown in dotted lines in Fig. 2; When it is desired to fully collapse the copy holder to the full line position shown in Fig.. 2. to house the copy holder with the typewriting machine in a drop cabinet, this may be-readily and noiselessly effected as will hereinafter appear.

In the accompanying drawings I have shown an L-shaped base comprising Vtwo wooden members 1 and 2 which are Vpreferably detachably united or hinged together by .suitable means to enable the copy holder to be compactly packed when desired. In the 'present instance screws 3 may be regarded as the equivalent of a desk or table to which the copy holder is secured.

Two pa allel upright guide tubes or sleeves 5 are rmly secured at their lower ends by screws 6 (see Fig. 5) to a metal base plate '7 which in turn is fastened by screws 3 and 8 to the base member 1 or to the top of a desk or table. Received and telescoping in each guide tube 5 are two tubular members 9 and 10 respectively and an inner telescoping solid rod 1l. Any suitable means may be provided for limiting the telescoping movements of the members 9, 10 and 11 relatively to one another and'to the supports 5. Thus, by referring more particularly to Fig. 'I it will be seenthat the member 9 carries a sleeve 12 which is fixed at the lower end thereof ber 9 in the tube 5. The sleeve12 also coacts with a like sleeve 13 secured to and projecting inward from the companion guide member 5 to limit the upward telescoping movement of the tubular member 9 in its guide 5. In a like manner the tubular member 10 has a sleeve 14 xed at the lower end thereof and cooperative with a sleeve l5 secured to the member 9 at the upper end thereof. The lower end of the rod l1 carries e. sleeve 16 that coacts with a sleeve 17 iixed at the upper end of the telescoping member 10. In this manner the.members 9, l0 and 1l are guided and the upward telescoping movements thereof to the dotted line position in Fig. 2, and relatively one to another and to the associated guide tube 5, are limited.

The upper reduced end of each rod 11 is seated in an opening `in a cross bar 19 that carries a pad 20 at the under side thereof. This pad in the present instance comprises two sections with an intervening space between them and is made of sponge rubber but may be of felt, cork or other suitable material. A sheet metal supporting bracket 21 is securedby the screws 18 to the cross bar 19 and extends upward and then backward to form a sheet metal paper guide and support 22. Rearwardly projecting brackets 23 are supported on the guide 22 at the ends thereof and these brackets are apertured to provide bearl clamping rollers 28 which are adapted to bearv against the outer face of the sheet to be supported by the copy holder and press it against a depending sheet metal plate or support -29 against which the copy sheet .is pressed by the rollers 28 and which is xedly connected at its upper rearwardly bent end tothe bracket 21.

In order to cause the rollers 28 to press against the copy sheet each collar 26 carries e.l pin 30 to which one end of a contractile spring 31 is attached, each spring being anchored at its opposite end to the bracket 21. 'I'he force of these springs is thus exerted against the bail to force the rollers 28 to grip the copy sheet and hold it in place at the upper end portion thereof. By swinging the bail 25 upward and back to an ineifective position the upper ends of the springs 31 will be carried to the rear of the pivotal center of the arms 24. 'I'he springs 31 will then exert their force to maintain the bail in its released position.

When using the copy holder to support a stenographic notebook, or attached sheets for example. the unused or copied leaves thereof may be bent back over the top of the support 22 and-be held under a long contractile spring 32 which is anchored at its ends to the brackets 23.

The upper line indicating edge of a sheet metal line indicator34 stands adjacent to the depending plate 29 and successively registers with the lines of the copy as the latter is elevated a line at' a time.

Rollers 33 are received in cut-out portions in the eective edge of a sheet metal line indicator 34 and are carried by and project beyond the indicating edge of said line indicator, for purposes which will hereinafter appear. The line indicator is turned at its lower edge and pivotally supported to turn on a. wire bail 35 with sumcient friction thereon to remain -in the position to which it may be pivotally adjusted on the bail. Each of the upper inwardly turned ends 36 of the bail 35 receives a bearing in a depending sheet metal bracket 3'? secured at its upper end to a cross bar 38 to be hereinafter described. There is suiiijcient friction on each arm 36 to hold the bail in any position to which it may be adjusted around its pivotal center.

In the event that the plate 29 should be dropped from a height where the lower edge thereof is above the line indicator 34, and the indicator is adjusted too close to said plate, then the lower edge of said plate 29 will contact with the rear inclined faces of the rollers and be deflected rearward and clear the line indicator instead of catching thereon and preventing the plate from dropping to its initial position, as might occur in the absence of the rollers 33.

The upper section of the copy holder, comprising the cross bar 19 and the parts carried thereby including the plate 29, rollers 28 etc., has power directly transmitted thereto to expand the copy holder from its most compact position shown in full lines in Fig. 2, to the fully expanded dotted line position shown in this figure.

, There is another cross bar 39 similar to and underlying the cross bar 19 and to which the upper ends of the tubular members l0 are attached. This cross bar 39 also carries a supporting plate 40 which is in the rear of and is overlapped by the similar plate 29, and is provided with a pad 39' on the under side thereof. Each pad is made of two sections with an intervening space between them. In a like manner the cross bar 38, hereinbefore referred to, has the upper ends l 1,995,74o` /v up the copy holder are moved to an expanded po` sition and may be brought into contracted tionship will now be described.

As shown in Fig. 6 the upper end of a flexible relacontrolling, moving or driving member, or follower in the nature of closely coiled spring 43, receives the exterior threads of la'nut or screw 44 that is interiorly threaded to receive the'stem of a screw 45 by which the flexible moving member 43 is xedly connected to the cross bar 19 midway in the length thereof. There should be a slight play between the`screw 45 and the cross bar 19 to prevent a throwing of the spring out of line when the screw is tightened. The drivingk thereof that faces a drum 47 mounted to turn on a horizontal axis. The guide 46 is arranged tangentially to, and at its lower end registers with,

a channel 48 provided in the rear side of the drum 47 near the periphery thereof. Thedower end of the flexible driving member 43 is fastened, asiat 49, in the channel '48.- From an inspection of Fig. 4 it will be seen that member 43'is entirely the -drum of which said disk forms a part is then surrounded by the'guide 46 and the walls of the channel of the drum and in the plane of said channel so that the exible member is accurately guided in said plane as it moves into and out of the drum during the turning movement of the latter.

An upstanding bracket plate 50 is secured to the'base plate 7 and forms a support'for the guide 46 which is connected thereto by a screw 51. The

A `bracket50 forms a continuation of the guide 46 `alongthe rear wall thereof and forms a further means for retaining the flexible member-4 3` in the drum channel. v*The bracket 450 hasa stub shaft :52 riveted thereto at 53 and onthis stub shaft the drum 47 and ,other devices, 'to be hereinafter described, are mounted-to turn.-'

prises the 'following' elements. A hub,4 54 rev-- p Inpractice'I prefer 'to mount the drum47 fas close as possiblevtothe right hand guide tube 5 in order to bring about as nearly as possible a,

straight vertical movement offthe flexible member 43 between'the point where itleaves the 4and its point of Vconnection with thel bar 19.

Referring more particularly to Figs. 4, 8 andf9, it will be seen thatlthe drum which isdesignated as a whole by the reference'numeral 47 comceives a bearing onthestub shaft 52-and is held v against displacement therefrom by av headed screw 55,received at its threaded end in a tapped.: openingin the end of the stub shaft. The sheet metal portion of the drum is fixed by screws 56 and a dowel-pin 57 to the hub 54 and to a disk 58, the periphery of which is adapted to be gripped by roller clutches to eifect an intermit of the drum. A corresponding depending membei 60 is pivotally supported in a like manner on the hub 54, the two members 59 and 60 being maintained separated at their lower ends by a spacing block or plate 61, all of the elements 59, 60 and 61' being riveted together at These elements constitute a pivoted carrier for a clutch roller 63 loosely confined between the two members 59 and 60 and resting on therupper inclined edge or tread of the spacing block 61. Said clutch roller is adapted to coact with the periphery of the disk 58 to clutch lthe latterto move with the carrier 59, 60'when the latter is moved in a clockwise vdirection from the normal position as the `parts are shown inFig. 8. A forwardlyextend- Ving'ear 64 is provided on the member 60 and said ear carries a pin on which is received a coiled expansion spring465. One end of this spring bears against the ear 64, whereas the other end of the spring bears against the clutchyroller 63 tending to force the latter into clutching engagement wlththe contact face on the block 61 'and with the periphery of the disk 58. An ear 66 extends forward from the fixed bracket 50 and is tapped to receive a screw 67, the inner end of which screw constitutes a stop or abutment with which the clutch roller 63 coacts. The screw stop 67 may be held fixed in its adjusted position by a lock nut 68. It follows therefore that when the 'clutch roller-carrier59-60 is moved to the right l from the normal Fig. 8 position, to that indicated in Fig. 9, the clutch roller 63 will `be released from clutching engagement with the disk 58, and

` members 9, 10 and 1l are sufficiently loose to permit this movement.

, Inv order to hold the drum against backward turning movement during the intermittent for- Ward feed movement thereof, I have provided a second clutch roller 69. 'I'his clutch roller is pivotally mounted l`in a yoke 7 0 that has a stem 71 guided in anopening in an ear 72 of a bracket `73.,V This bracket is secured by a screw 74 (Fig.

3*) to the .fixed bracket 50. An expansion spring 75 surrounds the stem 71 and is interposed bevftween the yoke 70 and the ear 72 and exerts its force against the yoke and tends'to f orce the I clutch roller 69 into contactive engagement with the'` periphery of the disk 58 and with'the upper` `contact face 76 of a bearing block or member 77 fxed tothe bracket 50. y i

backward turning movement of the .disk

58 and thev drum is ordinarily prevented -by the clutch Vroller 69. When, however, the device is manipulated to cause thecollapse of the sections ',to-.the'rst lineindicating positionv by a movement ofthe carrier 59, 60, to the Fig. 9 position,

this will' result in automatically releasing thel clutch roller 69 from its effective position as will now be pointed out.

'y `A releasing lever or device 78 (Figs. 8 and 9) is pivoted at 79 to the bracket 50. One arm of thislever extends below and contacts with the )roller 69, whereas the other arm of said lever excuil shifted to the position indicated in this figure. This results in shifting the roller 69 to the releasing position as shown against the force of the spring and holding it in this releasing position as long as the Acarrier 59-60 is held in the Fig. 9 position. At this time therefore, the drum is freed from control of the clutch roller 69 as well as from control of the clutch roller 63 and the drum is free to turn backward and lower the sections of the copy holder.

I will now describe the means for controlling the -movements of the carrier .5S-,450 to bring about a feed of the drum, or its release, as hereinbefore pointed out.

As best shown in Figs. 8 to 14 inclusive the carrier 59, 60 is connected to one end of a link 81 which has its opposite end pivoted at 82 to a crank arm 83 4secured to a hollow shaft section 84. This shaft section is supported in a bearing opening in a U-shaped bracket 85 secured by a screw 86 to the base plate 7. A second shaft section 87 has a stem that is received in the hollow section 84 of the shaft and is secured therein by a pin 88. 'Ihe section 87 lalso has a hollow portion that receives a ball 89 from which project in opposite directions two pins 90. These pins extend into slots 91 in the walls of the hollow portion of the section 87. This provides a universal joint between the shaft sections so that'an accurate alignment thereof when mounting the copy holder on its support is not so essential. The ball 89 constitutes one end of a shaft section that comprises the solid member 92 and a hollow member 93 xedly 'connected together by pins 94. The hollow member 93 receives a shaft section 95 and is slotted longitudinally at 96 to form a clamp which is tightened against the shaft section 95 by a split collar 97 contracted by a screw 98 so as to rmly, though detachably, unite the two shaft sections 95 and 92-93. 'I'his construction provides a means for readily lengthening or shortening the shaft 93, 95 to accord with typewriting machines of different lengths with which the copy holder may be used.

The forward end of the shaft section 95 has a bearing received in an opening in an arm 99 forming part of a bracket 100 secured by screws 101 to the base member 2 or to a desk or table top. In this manner the connected members 92-93, and 95 turn together in order to transmit a rocking movement to the crank arm 83, and may also receive a longitudinal movement relatively ,to the shaft section 87 without becoming disconnected from the latter, for purposes which .will hereinafter more clearly appear. A coiled expansion spring 102 bears at one end against the bracket arm 99 and at the other end against a collar 103 secured by a screw 104 to the shaft section 95. One end of the spring is secured to the collar at 105, whereas the other end of the spring is anchored to the bracket arm 99 as indicated at' 106. In this manner the spring 102 not only exerts its force lengthwise of the shaft, or to the right as the parts appear in 10, but also tend to turn the shaft and restore it and the parts controlled thereby to normal position. By effecting an adjustment of the collar 103 longitudinally of the shaft the expansion force of the spring on the shaft to resist the longitudinal movement of the latter may be varied. By .a circular adjustment of the collar 103 on the shaft the force of the spring exerted to turn it and return the parts to normal position may be varied.

The construction of the shaft and its mounting, as thus far described, facilitates the assembly of Y dle B.

the parts and also affords a longitudinal movement of the shaft without disconnecting it from the devices which control the drum 47, for purposes which will hereinafter more clearly appear.

Referring more particularly to Figs. 9 to 14 inclusive it will be seen that the forward end of the shaft section 95 has a crank arm 107 fixed thereto with the aid of a pin 108 or by any suitable means. Connected to this crank arm is a link 109 that is` pivoted at its opposite end to a manually controlled lever 110 -pivoted at 111 on an karm 112 forming part of the bracket 100. 'I'his V lever is provided with a finger piece or handle 110 (Fig. 1) at its forward end and has tapped ears 113 that receive a screw stop 114 carrying a padded stop 115 at the lower end thereof. The stop 115 coacts with a laterally projecting eax or stop 116 on the bracket arm 112 to limit the movement of the lever in one direction from its normal position, i. e., in the direction of its actuating movement effected by depressing the han- In order to hold the screw 114 against accidental displacement from its adjusted position I have provided a friction spring 117 (see Fig. 14) provided with a seat 118 that bears against the screw 114 and tends to hold it against turning movement, the free ends of the spring bearing against the lever 110 and maintaining the spring under tension.

From the foregoing description it will be understood that an adjustment of the screw stop 114 varies the extent of actuating movement that may be transmitted to the lever 110 and therefore determines the extent of actuating movement that may be transmitted to the carrier 59- 60. It follows that this determines the extent of line spacing movement that is transmitted through the member 43 with a pushing force exerted thereby on the copy holding section at each actuation of the lever 110.

The following means are provided to limit the movement of the lever 110 in the opposite direction from its normal position, or the releasing movement of the lever effected by lifting the handle 1101e1 instead of depressing it as previously described.

An extension 119 on the lever 110 coacts with a stop screw 120 carried by the bracket arm 112 to limit the movement of the lever when the handle 110e is lifted in its releasing movement.

The lever 110, the shaft connected therewith,`

and the parts controlled by the shaft are limited in their return movement to normal position under the force of the spring 102 by a stop stud 121 (Fig. 13) projecting from the forward side of the bracket arm 99. -This stud or stop 121 coacts with a laterally extending projection or stop 122 on the crank arm 107 to limit the return movement of said crank arm, and the parts connected therewith, under the action of the spring 102. However, when it is desired to move the parts to the Fig. 9 position and thus release the clutch rollers 63 and 69 and permit the copy sheet holding section to return to the first line indicating position, this may be readily effected by moving the crank arm 107 beyond the position where it is normally arrested by the coaction of the stops 121, 122 as will now be described.

, From an inspection of Fig. 13 it will be seen that each of the coacting stops 121, 122 has a bevel or cam face where it coacts with the cooperative stop. The cam on the stop 121 is indicated at 121e, whereas the cam on the stop 122 is indicated at 122B. These stops coact effectively to arrest .the parts in their return movement to normal position under the action of the spring 102. When, however, a greater force is exerted on the parts by lifting the handle 110* this brings the camming action of the stops into play with the result that the crank arm 107 and the shaft to which it is connected will be cammed forward against the expansion force of the spring 102, thereby enabling the stops 122 to clear the stop 121 and bring about a movement of the parts-'to the Fig. 9 position and effect a release ofthe clutches. The longitudinal movement of the shaft thus brought about is permitted by the sliding connection between the shaft sections 87, 92. The parts remain in the condition described as long as the handle 110e is held elevated by the operator due to the fact that the high points or dwells on the cams 121e and 122a coact to prevent a rearwa'rd movement of the crank arm 107 and the shaft to which it is connected. When the operator releases the handle the shaft will be rotated by its spring 102 and when stops 121, 122 reach normal relation the spring 102 will shift the shaft rearward thus bringing about a restoration of the parts to normal position.

Thus far VI have referred to dropping or returning the copy sheet carrying section to the first line indicating position. where the first line of the copy is in register with the line indicator 34, and have pointed out that such position is higher than the fully collapsed position represented in Fig. 5 andin full lines in Fig. 2. This is in order that the copy holder when in use may support the line indicator 34 -above the typewriting machine 123 arranged in front of the holder, as indicated in dotted lines in Fig. 2, and clearly present the matter to be copied to the operators view.

I will now describe the means by which the arrest of the copy holding-section may bearrested in the first line indicating position each time the handle 110 is lifted and which are nevertheless so constructed to enable the copy holder to be fully collapsed to the full line position shown in. Fig. 2 when it is desired to condition the holder for non-use and for storing in the drop cabinet with the typewriting machine.

From an inspectionof Figs. 2, 3 and 5it will be seen that a sheet metal arresting member or frame comprising depending arms 124 united by a cross bar 125 is pivoted at 126 to bracket arms fixed to the under side of the cross bar 38. Secured to said cross bar'are upwardly-extending finger pieces 127 by which the frame may be given a pivotal movement' to releasing position. A leaf lspring 128 is fixed at its upper end to a sheet metal arm 129 secured to the crossbar 38 about midway in the length thereof. 'I'he lower end of this spring bears against the cross bar 125' below the pivots 126 thereof and tends to force l the arms 124 of the frame forward to a position in Fig. y3 and in dotted lines in Fig. 2, Vvand, the4 spring 1281vill automatically cause the stop frame' to move to this position assoon as the cross bar 38 has been elevated high ienough to enablethe arms 124 to snap forward to a position to coact, with the crossbar 42, and thereafter the sections will always yreturn to this position' when the handle 110" is elevated to release the clutch" rollers 03' and 89.'

When the operator desires to fully collapse the copy holder to the full line Fig. 2 position, also shown in Fig. 5, it is merely necessary to press forward on the finger pieces 127, or either of them, and elevate the handle 110L thus permit.

ting the parts to drop to the fully collapsed position.

From an inspection of Figs. 3 and 6 it will be seen that each of the cross bars, 19, 39, and 38 is provided with a depending centrally vdisposed guard arm 130 secured thereto at the upper end of the arm. These arms overlap but are preferably free from contact with one another and are arranged directly in the rear of the flexible member 43 to prevent the latter from being grasped and bent by thev operator or otherwise interfered with.

I vprefer to house or partly house the various working parts of the construction by detachable cover plates. Thus a front plate 131 is mounted in front of the drum 47 and its connections and extends from side-to-side of the copy holder. A projection 132 on this plate covers that part of the drum that extends beyond one side of the copy holder. A corresponding vcover plate 133 is arranged at the rear side of the copy holder. Both plates 131 and 133 overlapat their ends to enclosethe parts at the sides of .the copy holder.

From the foregoing description it will be understood that I have provided a highly effective copy holderthat is'comparatively simple in construction,`that is substantially noiseless in its operation and whichvmay be readily fully co1- lapsed when not in use, so that it may be stored with a typewriting machine in a drop cabinet when desired or when not in use.

Various changes may be made in the con-` struction, and certain of the features thereof may be employed without others, without departing from my invention as it is dened in the accompanying claims. y l,
