45 Claims.

My invention relates to copyholders and the objects of the invention, generally stated, are as follows: 7 To provide' a highly effective and easily manipulated copyholder for indicating the lines successively, line at-a-time as they are being copied.

To provide simple and efficient means for intermittently, successively and noiselessly feeding position to which the work sheet carrier may have been intermittently fed.

To provide improved means whereby the copyholding member may be readily expanded to its fullest 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 copyholder 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 of the 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 combinations of devices set forth in the following description and particularly pointed out in the appended claims.

- Figs. 11 and 1 2 are detail perspective views of the detents for parts of the structure to be hereinafter described.

Generally stated, the present construction involves a work sheet carrying member that may be intermittently and noiselessly fed to an expanded position, represented in dotted lines in. Fig. 2, and may at will-be readily and noiselessly returned to the first line indicating position, represented in Figs l and 3. When it is desired to fully collapse the copyholder to the full line position shown in Fig. 2, and as represented in Fig. 5, to house the copyholder 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 two wooden members I and 2 which are preferably detachably united or hinged together by suitable means to enable the copyholder to be compactly packed when desired. In the present instance screws 3 firmly connect the members I and 2 together. The base member .I constitutes a support for the copyholder proper and the member 2 constitutes a support for the manually controlled handle and certainof the connections controlled thereby. However, the so-called base members I and 2 may be dispensed with and the copyholder secured directly to the top of a desk or table on which itis to be supported. For the purpose of the present case the base members I and 2 may or to the top of the disk or table.

be regarded as the equivalent of a desk or table to which the copyholder may be secured.

As best shown in Figs. 3 and 5 a fixed guide tube or sleeve 5 is fitted at its lower end in an opening in a metal plate or block 6 secured by screws 6 to a metal base plate 6 which in turn is fastened by screws I to the wooden base member I, Received and telescoping in the guide tube 5 is a tubular member 8 received at the upper and lower end portions thereof with a snug fit in the guide tube 5 which nevertheless permits the member 8 to slide freely In a like manner within the guide member 5. an inner telescoping solid rod 9 is received in the tubular member 8 and has a snug fit at the top and bottom thereof within said member 8. Any suitable means may be provided for limiting the upward telescoping movements of the members 8 and 9 relatively to one another and to the supporting tubular member 5. ring more particularly to Fig. 5, it will be seen that the member 8 is provided at the lower end thereof with a head I0 that has a circumferential flange that extends beyond the outer diameter of the tube 8 and is adapted to coact with a shoulder I I near the upper end of the guide tube 5 to limit the upward movement of the member 8. In a like manner the rod 9 is provided with a head I2 that has a circumferential flange that projects beyond the diameter of the member 9 and is adapted to coact with a shoulder I3 near the upper end of the tubular member 8 and thus v limit upward movement of the member 9 relatively to the tube guide member 8.

In order to further secure the tubular guide member 5 in place I provide a cross brace I4 (see Fig. 3). which is secured at its ends by screws i5 to upright supporting members I6 The members I6 constitute rearwardly and inwardly turned parts of an upright sheet metal supporting plate I6 that is coextensive with the width of the copyholder and is fixedly secured at the lower end thereof to the metal base plate 6. The upper edge of the plate I6 terminates at about the height of the bar I4, as shown in Fig. 5. The cross brace I4 is fixedly though detachably connected to the fixed sleeve 5 by a screw II, as shown in Figs. 3 and 5, to firmly hold the sleeve in place.

I preferably provide a rubber disk I8 in the lower end of the tubular guide 5 and which rests upon a closing block I9 in the lower end of saidtubular guide. The purpose of this construction is to seal the lower end of the tubular guide so that said guide and the member 8 may operate in the nature of a dash-pot to prevent too rapid a movement of the guide members and the parts connected therewith when they return to collapsed position. In a like manner the inner guide member 9 in a measure coacts with the tubular member 8 to form a dash-pot.

Referring more particularly to Fig. 3 it will be seen that the upper end of the inner rod 9 is connected by a screw 20 to a cross head 2|. This cross head carries two depending pins 22 near the outer ends thereof, each provided at its lower end with a head 23. These pins 221 are received and play freely in openings in a bracket plate 26 that is secured to a member of a lazy :tongs, designated as a whole by the reference numeral 25. This connection between'the headed pins '22 and the lazy tongs provides a lost motion connection between them, so as. to afford a limited extent of independent movement between such parts when the copyholding member Thus, by refer- 30 is closely approaching and is being moved from its fully collapsed position in a manner and by means which will be hereinafter described. As the lazy tongs are moving to their fully contracted position from that shown in Fig. 3 the rod 9 will be arrested first. The bracket 24 will then move down independently of the arrested pins 22 during the final collapsing movement of the lazy tongs; the heads 23 limiting the final extent of this independent movement. During the upward movement of the copy-sheet carrying member 39, by means to be hereinafter explained, the lazy tongs will be expanded, first carrying the bracket 24 up on the pins 22 until said bracket reaches the cross head 2|, as shown in Fig. 3. This will result in lifting the rod 9 and successively expanding the telescoping members 9'and 8 relatively to the fixed member 5. Each of the two lower members of the lazy tongs is connected by a pin and

slot connection

26, 21 to the upright supporting plate I6, so as to permit a slight horizontal movement of these lowermost members of the lazy tongs during the expansion and contraction of the lazy tongs.

Ina like manner the uppermost members of the lazy tongs are connected by pin and

slot connections

28, 29 to a sheet metal member 30 that extends throughout the width of the copyholder and is bent to the rear at the upper end thereof as shown in Figs. 1, 5 and 6. This member 39 constitutes a copyholding member as will hereinafter more clearly appear.

The lazy tongs are further guided by a pin 25 carried thereby and which moves in an upright slot 25 in the supporting plate I6 as best shown in Figs. 3 and 4.

From the foregoing description it will be understood that as the lazy tongs are expanded by an elevation of the copy-carrying member 39 the rod 9 will be elevated. On the other hand; when the lazy tongs are contracted during the lowering of the copyholding member 39 the rod irrespective of the position to which the copy holding member 39 is raised or lowered. The lazy tongs also maintains the copyholding member against a pivotal movement around the telescoping guide members.

In order to further properly guide the copyholding member 39 and prevent it from moving forward or back or sidewise, I have provided a depending sheet metal guide 3| which is fixedly secured at its upper end, as indicated at 32, to the copyholding member 39. The guide member 3| is slotted vertically at 33 to receive a headed pin 34 carried by one of the members of the lazy tongs. This guide in cooperating with the lazy tongs also prevents a side displacement of the copyholding member relatively to the lazy tongs.

From an inspection of Figs. 1, 2 and 3 it will be seen that the copyholding member 30 is provided at the ends thereof with rearwardly extending bracket arms 35. Each bracket arm is pierced to receive one of the longitudinally extending bearing end portions 36 of a bail 31. Each part 36 is surrounded by a coiled spring 38 which is fixed at one end thereof to a collar 39 secured by a set screw 49 to the companion bearing arm 36. The other end of the spring is fixedly secured to the companion bracket 35, as indicated in Fig. 12. As shown in this figure the end of the spring 38 which is connected to the associated bracket is received through a pierced opening therein and extends upward outside of the bracket where it is provided with a raised portion 4! that coacts with a crank arm portion 3-2 of t -e bail and constitutes a detent to hold the bail in its released position. Each spring 38 is shaped to form such a detent so as to maintain the bail in a substantially horizontally disposed released position when the bail is shifted to such position. The cross bar of the bail extends across the copyholder and is provided with a series of rollers 43 which by means of the springs 38 are pressed against the depending portion of the copy carrier 30, or the interposed flexible copy sheet supporting member 44, as will hereinafter more clearly appear.

A second sheet metal clamping member conforming in part to the shape of the work sheet carrying member 30 is secured thereto by screws The lower clamping edge 4'! of this plate bears against the upper edge of the flexible sheet or member 44 and with the aid of the screws 46 fixedly connects the upper end of such flexible member and the copyholding member 35. The

bail 31 is effective to clamp the upper end of a sheet to be copied against the depending portion of the copyholder 30 or the sheet 56 interposed between said copyholding member and the bail, and thereby cause the copy sheet to be elevated with the copyholding member 30 as the latter is intermittently fed upward, as will hereinafter more clearly appear.

The lower end of the flexible sheet 44,'which may be of a textile fabric or other suitable material, is secured to a roller 48 mounted at its ends in bearing brackets 69 carried by the metal base plate 6. This roller is provided with a coiled spring 50 (see Fig. 5) which tends to turn the roller in a clock-wise direction as the parts appear in this View and to take up and wind on the roller the flexible sheet 44 as the work sheet carrying member 30 moves down from an ele- 0 44 primarily to maintain it taut at all times, al-

vated position. The purpose of the flexible sheet 44 is to provide a support against which the copy sheet or sheets may bear to prevent the latter from coming in contact with the lazy tongs or other working parts of the structure when the member 30 is in an elevated position. The force of the spring is exerted on the flexible sheet though some of the force of the spring is exerted to return the copyholding member 3|] and the parts connected therewith when said holding member 35 is lowered. This latter effect, however, is unnecessary, since the weight of the parts, ordinarily is sufficient to return them to lowered position.

From a consideration of Figs. 1, 2 and 3 it will be seen that each of the upright portions 16 has a bracket 5! secured thereto, at 52, near the upper end thereof. Each bracket is provided with a cylindrical rubber buffer 53 with which the associated bracket 35 coacts to limit the downward movement of the copy-carrying member 35 when the latter moves down to its lowermost position, shown in full lines in Fig. 2. These rubber buffers therefore constitute the means for limiting the downward movement of the copyholding member 30 and the parts carried thereby. This is a fully contracted position of the copyholder to enable it to be conditioned for non-use or to enable it to be received in a drop cabinet with the typewriting machine when the latter is received in such cabinet.

I have provided a line indicating plate 54 which inthe present instance is mounted on lazy tongs comprising two members 55 and 56 (see Fig. 1) pivotally united at the centers thereof, as indicated at 51. One end of the member 55 is pivotally connected at 58 to the line indicating plate 54 near one end thereof. The other end of this member 55 is pivoted at 59 to a block 60 mounted for sliding and pivotal movement on the headed pin 6|. Said pin projects from an arm 62 fixedly connected to a rock shaft 63 that receives a bearing in the brackets 5| and extends in the rear of the eopyholder from side-to-side thereof. A coiled expansion spring 64 surrounds the shaft 53 at one end thereof and tends to exert its force longitudinally on the shaft to move it to the right, or to the left as the parts appear in Fig. 3. Secured to the shaft 63 near the other end thereof is a crank arm 65 provided with two stops 65 which coact with a fixed pin 5? projecting laterally from the outer face of the companion bracket 52. The arm 55 is provided with two openings or recesses 68, one or the other of which is adapted to coact with a rounded projection 69, as shown in Fig. 11. This constitutes a detent to hold the shaft 63 and the parts carried thereby against accidental displacement from either the full line or the dotted line position shown in Fig. 2. In the full line position the parts are positioned for non-use or for storage and with the line indicator overlying the work sheet carrying member 35, whereas in the dotted line position the parts are conditioned for use. The left-hand end of the lazy tong member 55 is pivoted at 18 to a block H which in turn is mounted to receive a pivotal movement around a headed pin or screw 12 connected to the lefthand arm 13 which corresponds to the arm 62 that is fixed to the shaft 63.

From the foregoing description it will be understood that the line indicating plate 55 not alone is adapted to move with the shaft 63 from the dotted to the full line position shown in Fig. 2, but that said indicating plate is also free to turn on its pivotal center 6!, 12, the parts being sufiiciently friction tight to hold the line indicator in any such angular position to which it may be turned on its pivotal center. This enables the line indicator to be adjusted closer to or further from the copy to compensate for various thicknesses of copy, and also to be adjusted out of the path of the ball 3? and the rollers it carried thereby, and enables the latter to clear the-line indicator when the copy-holding member is lowered to its lowermost position.

It also will be understood that the lazy tong mounting provided for the line indicating plate 54 enables it to be moved on its supports 60, ll

. to various positions parallel with its pivotal center 6!, 12, thereby enabling the line indicator to be moved to and maintained at different eleva-- tions. It will be understood that in such movements of the line indicator the right-hand end of the lazy tong section or element 56 will receive a sliding movement relatively to the line indicating plate by reason of the pin and slot connection l4, 15 by which said lazy tong element is connected with the line indicating plate 54.

In order to limit the downward movement of the copy-carrying member 30 and the parts carried thereby to the first line indicating position, I have provided automatically operating devices which I will now describe. Referring more particularly to Figs. 1 and 3 of the drawings it will be seen that two stops 76 are pivoted on the headed pins 28 which connect the lazy tongs to the copy-carrying member 30. The weight of these parts 16 tends to move them to the posij tion indicated in Fig. 3 where they are adapted to coact with the rubber buffers 53 and limit the descent of the copy-carrying member 30 and the parts carried thereby. When it is desired to fully collapse the copyholder to the position indicated in full lines in Fig. 2 and in Fig. 5, it is merely necessary to swing the member 16 inward towards the center of the copyholder so that the lower ends of said members are out of cooperative relation with the rubber buffers 53. The copyholding member 3!) may then drop by gravity, aided, if this be found necessary, by the pull of the spring 50 exerted through the sheet 34, to lowermost position. This movement is free from control of the members 16 which at this time coact with the inner sides of the buffers 53 which hold them in ineffective position. As soon, however, as the copyholding member 30 is again elevated to a position where the arresting members 16 are free from contact with the buffers 53, said arresting members will by gravity move to the effective position shown in Fig. 3, where the lower ends of said members are adapted to coact with the bufiers and arrest the member 30 in its next downward or return movement. The effect of this arrest of the copyholding member by the arresting devices 16 is to locate the copyholding member and the parts carried thereby in the first writing line position where the line indicator 54, if properly adjusted, will register with the first line of the matter to be copied.

The means by-which the copyholding member 30 is intermittently elevated a line space at a time will now be described.

A bracket '17 (see Figs. 3 and 6) is secured to the rear side of the depending portion of the copyholding member 3!], as indicated at 18. A metal rod 19 is secured at its upper end to said bracket and extends through openings-in

guide brackets

80 and 8! secured by screws 82 to members of the lazy tongs 25. The lower end of the rod 19 is threaded at 83 for cooperation with a threaded bushing 84. This bushing is received and threaded into the upper end of a flexible controlling or driving member or follower 85 which is in the nature of a closely coiled spring that extends down from and forms a continuation of the rod 19, as indicated in Fig. 3. This flexible member or driving device 85 extends in a substantially straight line to and tangentially of a drum 86 on which the flexible member is adapted to be wound. That portion of the flexible member which extends in a substantially straight line to the drum intercepts the plane thereof as represented in Fig. 6 and is received in a channel or recess 81 in the front side of the drum, one end of said flexible connection being secured to the drum, as indicated at 88, in Fig. 3. I prefer to insert a flexible sheet metal strip 89 within the coiled flexible controlling member 85 throughout the length thereof in order to provide against a lateral deflection of that portion of the flexible member which is unwound from the drum and render it stiiTer against lateral deflection. From an inspection of Fig. 6 it will be seen that the drum 86 is slightly inclined so as to facilitate a straight line movement of the flexible member in its movement onto and off the drum. I also provide guide members 90, 9|, 92 which form parts of a bracket 93 fixedly secured to the metal base 5, as best shown in Figs. 4 and 7, in order to direct the flexible member 85 in its movement to and from the drum and to the channel 87 therein, the guide members 90, SI and 92 also preventing a lateral displacement of the flexible member from the channel in the drum. The flexible member 85 acts with a thrust or pushing force against the copyholding member 30 to elevate it.

Manually controlled intermittently actuated means are provided to turn the drum in an anti-clockwise direction, as the parts appear in Fig. 7, and thereby efiect a longitudinal thrust of the flexible member to elevate the copycarrying member 35. Said means include a ratchet wheel 9 secured by screws 95 to the drum to turn therewith. From an inspection of Fig. 4 it will be seen that the drum turns on a headed pivot screw 55 received at its threaded end 97 into a tapped opening in the bracket 93. A flanged bearing member 98 is fixedly connected to the drum at 99, and it is this member 98 that receives a support on the pivot screw 96.

An actuating arm Hill receives a bearing on the sleeve-like portion dill which constitutes a part of the member 98. This depending actuating arm constitutes a pawl carrier having a feed pawl H12 pivoted thereto at W3. A flexible sheet metal arm iM projects from the pawl and its flexible fingers Hi5 bear against the inner side wall of the drum 86. The engaging nose of this pawl m2 is adapted to coact with the teeth of the ratchet wheel 94, as shown in Fig. 7. An actuating link 305 is pivoted at H]? to the pawl-carrying arm i553 and a movement of said link from normal position in the direction of the arrow in Fig. 7 is efiective to turn the ratchet wheel 94! and the drum 88 secured thereto in an anti-clockwise direction. As the link moves in the direction of the arrow in Fig. 7 the frictional engagement between the fingers Hi5 and the inner face of the drum causes the pawl I92 to turn on its pivot IE3 at the first portion of the movement of said link and to thus engage the ratchet wheel. When the link IE6 is moved in the opposite direction as indicated in Fig. 8, the frictional engagement of the fingers i 635 with the inner face of the drum tends to cause the pawl N12 to turn on its pivot I63 out of engagement with the teeth of the ratchet wheel 94, so that in the return movement of the pawl with its carrier Ifiil the pawl will be maintained out of engagement with the ratchet wheel and thus provide a noiseless ratchet. In order to limit the movement of the pawl out of engagement with the ratchet wheel, I have provided a fixed stop pin m8 on the pawl carrier I98 and which coacts with the pawl to limit its outward movement.

In order to provide means for holding the drum against reverse rotation in a clockwise direction, I have provided a holding pawl I09 pivoted at M5 on the bracket 93. A contractile spring ii I is anchored at one end on a pin H2 that projects from the bracket 93. The other end of this spring is connected to the holding pawl Hi9 below the pivotal center thereof. The force of this spring is therefore exerted to move the nose of the pawl 509 into engagement with the ratchet wheel 94. A depending end H3 on the pawl extends into the path of movement of a laterally projecting pin i i i on the link I06. As the link H36 moves in thedirection of the arrow in Fig. 8 the pin H4 engages the depending end II 3 of the holding pawl and turns it on its pivot IIO to its releasing position, as shown in Fig. 8. In order to limit the extent of releasing movement of the pawl I09 I provide a stop lug II5 that forms part of the bracket 93 and extends into the path of said pawl. The pawl I09, like the pawl I02, is likewise provided with a flexible arm II6 having flexible teeth II! that bear against the inner side wall of the drum 85. The effect of this frictional engagement between the arm H6 and the drum is to automatically disengage and maintain the holding pawl disengaged from the teeth of the ratchet wheel 94 when the drum is moved in an anticlockwise direction by the feed pawl I02. As soon, however, as a step-by-step feed movement of the drum is completed and it starts to turn in the opposite direction, then the frictional engagement will cause the pawl I09 to engage the ratchet wheel and prevent a reverse rotation thereof.

The parts are maintained as they appear in Fig. 7 during the line spacing feeding operation of the drum in an anti-clockwise direction. I have, however, provided means for freeing the drum from control of its intermittently operating feeding means when it is desired to lower the copyholding member 30. This is effected by a movement of the link I06 to the left from its 30 normal position as shown in Fig. 8, instead of to 40. frictional engagement of the arm I04 with the inner face of the drum. The drum being freed at this time from the control of the pawls I02, I09, is free to turn in a clockwise direction as shown in Fig. 8, thus enabling the copy sheet 45. carrying member 30 and the parts carried thereby to move down to the first line indicating position shown in Figs. 1 and 3 where it is arrested by the stopping devices I6 coacting with the; rubber buffers I3. Should it be desired to still further lower the copy-carrying member 30, this may be done as hereinbefore indicated by moving the stop members 16 inward to disengage them from the buffers 53 when the copy-carrying member 30 is free to move to its lowermost position, shown in Fig. 5 after the pawls I09 and I02 are released as explained.

The means by which motion may be transmitted to the link I06, either to effect an intermittent feed of the drum or to free the drum from the control of the actuating devices therefor, will now be described.

As best shown in Figs. 1, 2, 9 and 10 the righthand end of the link I06 is pivoted to a crank arm II8 which is fixedly secured to a shaft section II9 supported in a U-shaped bearing member or bracket I secured to the right-hand upright portion I B as indicated at I2I. The forward end of this shaft section forms a tubular bearing I22 that is slotted longitudinally on- 70' opposite sides, as indicated at I23. A shaft section I24 carries an enlarged end I25 that is received in the tubular bearing portion of the shaft section II9. oppositely directed pins I26 carried by the enlarged portion I25 are received in the slots I23 to afford a limited sliding motion of the shaft section I24 relatively to the shaft section II9, but to connect the two shaft sections, nevertheless, to tiun together, for purposes which will hereinafter more clearly appear. The shaft section I24 is provided with an enlarged tubular portion I21 tapped to receive pointed set screws I28. A third shaft section I29 is received at one end in the tubular enlargement I 21 and is fixedly connected thereto by the screws I 28 both to turn and to move longitudinally therewith. The po;nted ends of the screws I28 are received in an open ended groove I29 in the shaft section I29. By these means the shaft I24, I29 may be relatively adjusted to lengthen or shorten the compound shaft to accord with difierent lengths of typewriting machines with which the copyholder may be associated. The forward end of the shaft section I29 is received in and projects through a bearing opening in a bracket I30 secured by screws I3I- to the base member 2. A finger piece I32 is provided at the outer end of a crank arm I33 secured to the outer'end of the shaft section I29 where it extends beyond the supporting bracket I30. The member I33 is also provided with an arm I34 that carries a screw stop I35 held in its adjusted position on said arm by a lock nut I36. The free lower end of the screw stop I35 coacts with a stop face I31 on the bracket I30 to limit the movement transmitted to the shaft I29, I24, I I9, in one direction, that is in the direction of its feed movement. It will be understood, therefore, that an adjustment of the screw stop I35 is effective to regulate the extent of line spacing movement transmitted to the compound shaft just described and the feed drum 86 controlled thereby. adjustment and regulation of the device to set it to accord with the spacing on the copy used on the copyholder.

I Referring more particularly to Fig. 10 it will be seen that the arm I33 is provided with a beveled face I38 adapted to coact with a beveled face stop I39 carried by and projecting laterally from thebracket I30 to limit the return movement of the arm I33 and the parts controlled thereby to normal position. It should be explained at this point that the compound shaft I29, I24 is free to receive a longitudinal move ment in its bearing I 30, as well as a turning movement in said bearing. A coiled expansion spring I40 surrounds the forward section I29 of this compound shaft and is fixedly connected at one end to a collar I4I secured to the shaft section I29 by a set screw I42. The other end of this spring is fixedly connected to the bracket I 30. The spring therefore has a twofold function, that of turning the shaft to normal position with the stops I38, I39 in contact and also of exerting a force longitudinally of the shaft to maintain the hub of the arm I33 in contact with one side of the bracket I30. The effect of this is to maintain the shaft sections in the relation shown in Fig. 9 with the pins I26 seated in the slots I23 near the rear ends thereof. Should the operator desire to release the drum from control of the intermittently operated actuating means which cooperate therewith, it is merely necessary to effect a downward movement of the finger piece I32 from the position shown in Fig. 1 where the arm I33 is arrested by a stop I33 The effect of this movement is to cause the compound shaft I29, I21 to be moved forward against the expansion force of the spring I40 due to the action of the cam faces I38, I39 which tend to bring about this longitudinal displacement of the This affords an,

compound shaft when force isexerted on the finger piece in the direction referred to. This turning movement of the shaft from normal position in a direction opposite to that which it takes during the intermittent feed operation is effective to move the link I06 in the direction of the arrow in Fig. 8 and effect a release of the pawls i 92, 1 E39 from engagement with the ratchet wheel 96 as shown in said figure, thus freeing the drum from control of its feed mechanism. The weight of the copy-carrying member 30 and the parts connected therewith together with the force of the spring 50 is then'efiective to cause the member 38 to be lowered, to turn the drum 8B and to wind the flexible driving connection 85' on the drum.

Referring more particularly to-Figs. 1, 2 and 4, it will be seen that I have provided a rear sheet metal cover plate 5 13 at the rear of the copyholder, said plate being detachably secured in place by screws Md which engage in threaded openings in rearwardly projecting posts I45 on the portions Ili of the supporting plate IS. The sides of the cover plate M3 are bent forward (see Fig. 4) to meet the members H5 and the working parts are thus fully housed when they are in the contracted position.

The copyholder is comparatively simple in construction, is easily manipulated, is highly effective in use, may be quickly conditioned for stor ing and is substantially noiseless in its operation.

Various changes may be made in the construction, and parts thereof may be employed without others, without departing from my invention as it is defined in the accompanying claims.
