The present invention relates to copy hold ers and an object thereof is to make is possible to feed sheets one at a timefrom a stack of sheets such as the sheets of a stenographers notebook past a line guide. Another object of the invention is to provide an improved means for feeding sheetspast a line guide of a copy holder. Still another object of the invention is to provide a copy holder which may be collapsed into small space in rear of a type-writing machine so that it may be enclosed in a cabinet with the machine and will not he required to'be removed from its .position in rear of the machine when the latter is not being used.

To theseand other ends, the invention'consists v of certain parts and combinations of parts. all of which. will be hereinafter described; the novel features heingfpointed out in the appended claims.

work support. The copy holder comprehends a line guide mechanism that includes a line. guide bar. The line guide mechanism is constructed so that the line guidebarthereof is positionable vertically along the front of and in respect to a plate of the worklholder in front of which plate the sheetsfare supported and in Fig. 9 the parts of'this line guide mechanism are shown in one of the positions wherein the line guide bar thereof occupies a relatively high position while'in Figs. 1, {L and 5 the parts of theline guide mechanism are shown in a position wherein the-line guide bar occupies a relatively low one side of supporting bar 3 as is clearly seen from Figure 1 in conjunction with Figure 4, to and projecting forwardly from the base bar 1 are twoclamps 7 which are-adapted to clamp upon the rear bar f the typewriting machine 5. Each of these clamps 7 comprises what may be termed the main or fixed jaw '7 and the movable jaw 7", as is clearly shown in Fig. 1. In this way, the copy holder may be secured in fixed relation to thet-ypewriting machine at the rear of the latter.

The base frame also-comprises two rodson guides9 projecting upwardly in parallel relation from the base bar 1. On this base frame is vertically movable an upper frame comprising, in'this instance, a plate 10 have ing semi-circular guides 11 at opposite vertical edges rolled rearwardly from the metal of which the plate 10 is formed and engaging'theouter faces of the guide bars 9 while leavingtheir' inner faces exposed. The lower edge of the plate is turned rearwardly at 12 to strengthen the plate. lViththe end in view of holding the upper frame in. raised position on the base or lower withdrawal 'of the upper frame from the lower frame the upper frame carries two detents 12 which are pivoted at 13 on the rear side of the plate and have each two detaining portions 14 and 15. The detaining portion 14 of each detent is in the form of a shoulder 16 adapted to enter a notch 17 in the adjacent rod 9 to engage ashoulder 18 at the top of the notch to limit the upward move ment of the upper frame on the base frame. The detaining portion carries a roller 19 at its free end to engage the upper end of the adjacent rod 9. Each rod has a beveled portion 20 over which the roller 19 travels. lVhen theupper frame is in its upper position the projecting shoulder 16 of each detent lies in a notch 17 and the roller 19 engages the upper end of the adjacent rod. The two detents are connected below their pivots by a single coil spring 21 which holds the de tents toward the guide rods 9 and causes the detents to sustain the upper frame in its raised position by engaging the upper ends of the rods 9. To lower the upper frame on the base frame, the upper frame is pushed downwardl v with pressure so that the rollers 19 ride onto the beveled portions 20 which shift the detents on their pivots to tension the spri g 21, and shift the portions 14 out of the notches 17, after which the rollers 19 ride down the rods 9 holding the detents against action until the upper frame is again moved to its uppermost position.

' The upper portion of the plate 10 is provided with a stiffening or reinforcing plate 10, the upper edge of which is deflected rearwardly atan incline at 22 and the matter 'to be copied is turned over this edge and is clamped to said inclined edge portion 22 of the stiffening plate 10*. When a stenographers notebook 23 is to be copied, the back and any number of pages are turned so as to have a position behind the rear face of the plate 10 and 10. the binding23 being situated at the deflected portion 22. The clamping of these turned pages may be effected by a clamp comprising. in this instance, an inverted U shaped swinging member 24, the arms of which are pivoted at 25 to the rear face of the upper frame member. Springs 26 act on this clamp to hold the horizontal portion toward the upper edge of the rearwardly inclined portion so that said ed e assists in the clamping action and forms a clamping member. Finger pieces 27 may be provided at the ends of the arms to provide means through which 7 the'clamp may be manipulated.

Associated with the upper work holding frame is a line guide past which the work is moved by a means such as that hereinafter described. This line guide comprises, in this instance, a rocking bar 28 mounted in friction bearings 29 on the rear face of the upper frame and having two rigid arms 30 at its opposite ends. Adjustable on said arms 30 are the arms 31 of a swinging U shaped member the connecting portion 32 of which has a guide plate 33 mounted to swing with friction thereon.

There may be associated with the line guide, a sheet guiding means which, in this instance, comprises two guides 34 projecting rearwardly from the rear face of the line guide and adjustable relatively to each other in the direction of the length of the line guide. In this instance, each sheet guide 34 has guide flanges 35 frictionally embracing the upper and the lower edge of the line guide so that the guides may be shifted to engage opposite side edges of the book leaves in front f the work holding frame. These guides cause the leaves to travel in straight lines past the line guide under the action of the sheet feeding means.

, The sheet feeding means comprises, in this instance, a plurality of axially alined feed rollers 36 arranged. on a shaft 37 so as to cooperate with theuppermost sheet at the front of the work supporting frame and directly in front of the rearwaardly deflected portion 22 slightly below the binding 23. The feed roller shaft 37 is" supported to move toward and from the work support and is held with yielding pressure toward the work. In this instance, the shaft 37 is supported by aswinging frame having a horizontal connecting portion 38 and two depending arms 39 which are pivoted at 40 to two-arms 41 extended forwardly from the ends of a bar 42 secured to the rear face of the work supporting frame as is clearly shown in Figs. 1 and 4. A stop 43 atthe lower end of one of these arms serves to limit the outward movement of the swinging frame and the pivots 40 are arranged in advance of the feed shaft 37 so that the weight of the swinging frame and the parts carried thereby hold the rollers 36 with yielding pressure toward the work. Springs 44 may connect the arms 41 with the arms 39 to still further insure the feed rollers being held toward the sheets to be fed, adjusting devices 45 being provided to vary the tension of the springs. The position of the springs 44 from one point of view in reference to the bar 42 and the swinging arms 39 is clearly indicated in Fig. 5, while the position of the springs 44 from another point of view in reference to the bar and swinging arms is illustrated in Fig. 1, wherein the adjusting means 45 is also clearly shown.

The shaft 37 carrying the alined feed rollers 36 has a step by step feed imparted thereto through the medium of step by step feeding mechanism comprising a clutch member in the form of a cup, including an annular flange 46, and has a bushing 48 rigidly secured thereto centrally thereof. This bushing embraces one end of the shaft 37 and is ifs late thereon. at 46* to the outer end of the aforesaid arm may be termed keyed to said shaft by means of a screw or edge of the flange of thecup'and an arm is loosely mounted on said bushing to oscil- A curved arm 46 is pivoted .the inner'surface of the flange of the cup whereby to ellect an alternate gripping and releasing dri'ving connection between. said lug onshoe's and-the interior of theannul-ar flange 46 ofthe cup.

It will be seen from the foregoing that the cup shaped clutch ine-mberthat includes the annular flange 46 and the curved arm l6 which provides the shoe'or lug 46 cooperate and provide'w'hat the friction members or elements of a step by step feedingclutch. his alternate gripping and releasing action is. effected in any suitable manner, one way being to connect a flexible pull wire with one end of the said curved arm 46 and which wire extends through a'flexible'sheath' 56 connected at 57to member39 and having its out.- er end extending into the s box 59 where it is attached at'5S.

A spring 52"acts on the arm 50 to return saidarm normally to starting position, the rear end of the curved arm 46 engaging the stop 53 to arrestthe return movement of both arms 46 and 50 at starting position. By virtue of this particular character of clutch mechanism it is possible to turn the shaftin-either direction in the operation of the copy holder, thatis to say, by the operating of the. clutch mechanism the step by step feed of therollers in a forward direction is enabled to'be carried out as and when desired or by means of the knob-or finger opera ed wheel 79, herinafter more fully referred tmthe feed rollers can be turned forwarcly freely or rearwardly against the friction holding or driving engagement of the clutch construction, whichnormally tenos to prevent er op pose such rearwardturnin movement;

Mechanism fore *ating the curved arm l6 and thereby the clutch mechanism isconr prehended within or is arried by a box 59 clearly shown in Fi 2 and 3. The operating mechanism and the box 59 therefor is arranged conveniently in respect tothe keyboard of the typewriting machine and himcured in place at theright front side of the typewriting machine is clearly shown in Figs. 1 and 3.

The box 59 forms a support for the wire or cable operating means and to this end is formed of two partsproviding a chamber 60 between them. In this" chamber is mounted a bell crank lever 61 having one arm connected to the lowerend of the pull. wire. The other arm has a pin and slot connection 62 withv a finger lever fi w-hichis pivoted at G L'tO 'thezcasing. spring 65 actson the pin 'ofthe ointbetweenitheftwoilevers and-returns the pull. wire to normal position after each depressioni ofithefingerlever '63. An adjust-'- able stop 66l1mits1the movement of-the cable operating :mechanism a;nd.,determ1nes the amount of the spacing'or feeding actio n'of the latter. The box 59hasa thin lateral. support 59 0n=its innerside' sothat the forward foot of a'typewr-iting machine may rest thereon. At the same time the b0 59 is clamped to the typewriting machine by a clamp comprising, in this instance, aborizontal lug 67 having avertical slot 68 andlproiectedfrom a forward extension 69 on the frame. The side frame of the'typewriting machine 5 rests against one face of this eX- tension while a set screw 70 en 'a 'es the opposite face and is-mounted in one arm of a substantially 'UVshaped-clamp 71 which is loosely fulcrumed in the :lug 67. Said clamp has a gripping portion 72 on the other arm to drawthe frame 59 against the frame of the typewriting machine. Between its ends the-sheathfiti is slidable in a loop 73 onanarm 75 supported fromthe base frame;

In order to enclosethe feeding mechanism, a" hood 76 is supported by the swinging frame 38l39 and extends above and below the hori: zontal portion 38 of. the frame, The upper portion of the hoodextends rearwardly and.

@n being thrown rearwardly the feeding rollers engage the top sheet in the pack adj a cent the upper part of the sheet holding mem-,

ber and upon being turned, the roller draws the top sheet upwardly until such a time that the lower edge of the drawn sheet passes width of the sheets. The feed roller is turned by a flexible cable which is enclosed in a sheath secured at one end to the roller support and at the other end to a support for a finger operated device. The latter support carries a novel means of securing it to the side of a typewriting machine in a position convenient for operation bythe' typist.
