Cooperating with the platen 9, to support copy against it for line by line advancement, is a. line guide member designated generally at D, includmg a cross. head 30 of substantially the same length as the platen 9, and two depending

hollow legs

31 and 32 arranged near the respective ends of the cross head.

For cooperating with the legs 3| and 32, vertically disposed rods E and F having L-shaped feet are supported on the base I.

The rod E has-a. lateral horizontal foot portion 33 and a vertical portion 34, while the rod F has a lateral foot portion 35 and a vertical portion 35. The

lateral foot portions

33 and 35 abut endwise within a clip I35 secured by screws I31 to the base along its front margin, ,for rocking 1 movement; Extending 1 rearwardly from the angle between the

portions

33 and 34 of the rod E, is anintegral foot extension 31 having a flattened end 38. In like manner, extending rearwardly from the angle of the rod F, is a similar foot extension 39 having a flattened end 40.

Supported for rocking movement along the rear margin of the base I is a shaft 4| having flattened portions 42 and. 43, which normally receive the flattened ends 38 and of the

extensions

31 and 39, of the rods E and F when the device is in operative position. The shaft 4| is supported in

clips

44 and 45 fastened by screws 46 to theIbase, as may be observed in Figure '7. Fastened to the left hand end of the shaft 4|, as viewed in Figure 7, is a crank 41 which atits outer'end is pivotally connected as at 48 to the slotted bar 28.

At the other end or the base I, that is the vright'h'and end as viewed" in Figure 7, the shaft 4( carries a mutilated gear-49 in mesh with the teeth 50a of an arm 50 pivoted by means of a screw 5| to'this endv of the base. The arm 50 has an upstanding part provided with an outstanding end 52 for overlying the lever 53 pivoted at 54 to the base. The lever 53, outwardlyof its fixed pivot 54, is pivoted to another pivoted lever which in turn carries at its free end a key. 55 adapted to be contacted by a finger of the typist to operate the platen in step by step movement. I

Pivoted to the end of the lever .53, adjacent the arm 50, is an upright member 56 which at its upper end carries a pin 56 entered in a slot 51 in an actuating bar 58 which works the platen.

The depending legs 3| and 32, of the line guide structure D, at their lower'ends encircle and receive the

upright portions

34 and 36 of the rods'E and 'F and are slidable along these por- The lower ends of the legs 3| and 32 are provided with'elongated cylindricalportions 59 and 60 for surrounding the. uprights of the rods E and F.

The effort exerted by'the springs 81 tends to maintain the roller 83 in contact with the platen.

8 to urge copy against the platen for advancement as the platen is given step by step rotative movement, as hereinafter described.

Guided in the upper ends of the side mem bers I and I, for horizontal movement, are plungers l0 operatively connected to the upper ends oi the levers i4 and I8, bypins ll carried by the piungersentered in notches I2 iormed in the levers. The cross head is aperturedto'allow through the cross head.

The upper ends of the locking bars 82 have integral plates 14 in the paths of-niovement of I the plungers l0. v

Normally the plungers :10 are retracted, as shown in Figure 6. As the plungers are moved outwardly, that is, to the left as viewed in Figure 6, by swinging of the'levers' I4 and ii, the

reduced ends" or the plungers pass through-apertures in the crosshead 80 and engage the plates 14 at the upper ends of the bars 82, thusbring-, ing the upper ends 'to the-right, as viewed in Figure-'2, and the lower ends to the left, which moves the lower ends out of register with-"the upper ends of the rods'E and F, thus 'unlatching the line guidestructure D,'ready for collapse.

Movement of'the plungers It to the left, as viewed in Figure 6, and to the right as viewed in Figure 2, causes entry of the reduced ends 13 of the plungers' into the apertures in the line guide structure D, thus connecting the line guide I a structure tothe upper frame member B of the device. As the levers and ii are rocked, as heretofore described, the'bar l8 connected'to the lower ends 01 thelevers l4 and", drops behind the rods 2' and 8 and remains behind therods' until the upper frame member Bis again ex tendedto operative position.- By reason of the ,fact that the levers l4 and I8 remain tilted out] of engagement, by reason 'of the position. or the rod, behind the

rods

2 and 8,'the plung'ers I0 are maintained in outward or projected position in connection with the line guide" structure D to connect the line guide structure to the upper frame member for simultaneous movement with it, downwardlyor upwardly, that is to say, into inoperative or operative position.

When the upper framemember is raised or extended, which is done by the operator grasping the knobs l i and I2 and raising the upper frame 3 structure, and as soon as the upper frame member reaches its uppermost position, the springs 28 become effective to move the lower ends of the levers I4 and I5 over the bar 4 thus latching the upper frame member in extended position. Movement of the levers in this manner retracts the plungers l0, whereupon the locking bars 62,

The outer ends of the members 15 and 18' are provided with knobs 11 wherebymovement orthesemembers may be easily accomplished.

d For supporting copy moved upwiirdly by the platen, a skeleton structure is provided, which is adjustable forwardly and backwardly, as the character oi the copy might require; 'j e Referring to Figures 1 and 6;.a honow' b if- 1a. having .a polygonal interior is, oscillatably mounted in the'upper ends of the? members-'1 and 8.

The outer endsof thepolygonally shaped bars 19 carry angularly shaped end pieces 80,which endpiecesare provided with telescoping bars 8l' and, 82 so arranged that thepolygonalbar's "l8 may be moved outwardly to their limit of travel with the b'ars8l and 82 still intele'scoping engag'ement, to provide an elongated copy guide greater in extent. than the length of the cross head 80 oi the line guide device C. The cross, head 80 is provided with a handle 83 whereby the cross head and the roller 83 may be pulled away from the platen for insertion fof copy between the roller and the platembe the copy a stenograp'her's notebook or a single sheet of paper.

Copy inserted between theroller and the platen will, on actuation of the platen, be advanced in step by step manner in accordance with the adjustment ofthe amount of feed of'the platen.

Copy may be-suspended in front of the typist, without engagingyit between the roller 88 and the platen, by means of a hinged member '84 which is secured to the front face of the cross bar ,bysuitable hinges and, tensioned by springs The 'means'for imparting step by step 'move-,

.ment to the platen 8 are the means illustrated in applicants'Patent No. 1,715,472, and herein illustrated for convenience, as follows: i

' At one end of the shaft ID of the platen, herein illustrated as the right hand end looking at ,the machine as illustrated in Figure 4, is a ratchet the shaft i 0.

Between the end member 8 and the ratchet wheel 86, a plate 81 is oscillatable on the shaft;

This plate is provided ,with a plurality or depressions or. holes 88, arranged on a radius, with which cooperates a depression 89- fprmecl in one end of a. spring 90 secured by bolts9l to the end member 8. The plate ,8! is .oscillatable about its wheel 86 secured by means of set screws867to shaft by means of a lever 82 so that any one oi 7 normally maintain the point of the pawl to the left, as viewed in Figure 5, that is.in position to engage a tooth of the ratchet 86.

The ofiset 93 of the lever 92 is so fashioned that thepoint of the pawl 94 normally bears against this ofiset behind the lever 92, as shown in Figure 5. ,Friie angular position of the lever 92, from that shown in Figure 5, to a position in which the detent 89 engages the right-hand depression 88 in the plate 81, controls the number of teeth of the ratchet disposed to action by the pawl point. As the parts are arranged in Figure 5, downward movement of the plate 58 will move the pawldownwardly, with its point engaging the tooth immediately beneath the ofiset portion 93 of the lever. The plate 58 is moved the same distance, every time, by actuation of the key 55.

To adjust the platen for two-stage movement, the lever 92 would be swung clockwise, so that the detent 89 would engage the middle depression 88 which would then shift theoifset portion 93 of the lever downwardly one space covering the tooth which otherwise would be engaged by the pawl with the lever in the position shown in Figure 5, limiting the advancement of the pawl to a two-stage movement.

A clicking pawl 91 is pivoted at 98 and has an outstanding latch 99 adapted to rest against the teeth of the ratchet when the pawl is lowered. In order to maintain the pawl out of clicking engagement, a lever I00 having an end IN adapted to engage with the pawl is suitably pivoted behind the ratchet and has an extremity available for manipulation by the operator. With the clicking pawl in the position shown in Figure 5, there would be no click apparent as the platen is rotated. With the lever I00 swung in counter clockwisedirection, to bring the latch 99 against the ratchet teeth, then clicking would occur when the platen is rotated as the spring H5 tends to urge the latch 99 against the ratchet teeth when the lever Hill is swung in counterclockwise direction moving its projection llll out of the way of the lower end of the pawl 91.

Figure 5 illustrates the arrangement of parts with the platen set to advance the distance of three ratchet teeth per movement, and without any copy between the roller 63 and the platen.

The device, when extended for use, has the appearance shown in Figure 4. The bars 8| and 82 may be endwise adjustable to accommodate the width of the copy used. If this is copy to be advanced in step with the platen, then it is inserted between the platen and the roller 63 and aligned with the upper margin of the cross head 30, which margin serves as a line guide. If the copy is not to be moved, then it may be supported between the cross head 38 and the member 84 and suspended in vertical position in front of the typist.

In order to extend the line guide beyond the length of the cross head 39, the members I4 and 15 may be pulled out, as indicated by dotted lines in Figure 4, to afiord a line guide comparable with the width of the copy utilized.

The copy holder may be collapsed as follows:

With the copy holder extended, as illustrated in Figure 4, and with the telescoping rods 8| and as viewed in Figure 2, pressure of the rollel 82 in full line position and the extensible guides 14 and I5 housed behind the cross head 30, the operator moves the thumb latch 24 backwardly, as viewed in Figure 4, and to the left, as viewed in Figure 2. Such movement, first of all, raises the slotted bar 28 thus rocking the shaft 4| and through it raising the overlying ends of the flattened end portions of the

extensions

31 and 39 of the rods E and F, to move them a short distance away from the platen, such for example as to the dotted line position of Figure 2. Such movement relieves whatever binding engagement there may be between the

cylindrical portions

59 and 60 of the legs 3| and 32 and the rodsE and F. When the bell crank C has been moved to bring the end of the pin 26 against the cran against the platen has been relieved. Continued movement then rocks the rod 2| to swing the crank 29 against the lower ends of the levers l4 and I5, which moves the lower ends and the connected bar l8 away from the bar 4 and at the same time projects the plungers' 10 to unlatch the bars 62 of the line guide device from contact with the upper ends of the

upright portions

34 and 36 of the rods E and F. As soon as the lower ends of the levers l4 and I5 are moved away from the bar 4, the upper frame member B drops slightly thus bringing the lower ends of the levers l4 and I5 behind the bar for maintaining the plungers l8 projected and connecting the line guide device with the upper frame member B. The operator then pushes the upper frame member down to the dotted line position of Figure 2, collapsing it together with the line guide device. As the upper frame member B is collapsed, that is, moved downwardly to inoperative position, the bar 58 slides downwardly with it, which it may do, as the pin 56 carried by the link 56 rides in the slot 51 of the bar 58.

As the shaft 4| is oscillated, in the manner just described, the mutilated gear 49 rocks the arm 50 to depress the lower end of the bar 56, thus imparting slight rotative movement to the platen, which movement may have some effect in moving the roller 63 away from the platen the instant the plungers 10 are projected.

To extend the holder, all that is necessary to be done is to grasp the knobs l I and I2 and raise the upper frame member until upward movement is stopped by engagement of the bar l3 of the upper frame member against the bar 4 of the lower frame member. When this contact is established, the lower ends of the levers i4 and I5 swing inwardly over the bar 4, by action of the springs 20, thus latching the upper frame member in extended position, and such lever movemerit retracts the plungers l0, whereupon the springs 61 urge the roller 63 against the platen 9 with sufficient frictional engagement to hold copy between the roller and the platen.

'If desired, a hood may be applied over the platen and the rear side of the upper frame mem ber. Such a hoodis herein illustrated at I82. Itmay be secured in position by screws or any other manner, and may be finished as desired.

that a stenographers book may be readily inmanufactured economically, on a production 7 basis.

The upper frame member latches automatically when it is moved to fully extended position, and may be lowered or housed by manipulation of a single member, to wit, the'thumb latch 24.

The bar 58 is normally maintained in upward position by means of a spring I03 connected at one end to the bar and at the other end to a pin I 04 on the end member 8 of the upper frame member. V

Figure 8 shows the manner of movement of the

extensions

31 and 80 of the rods E and F in accordance with oscillatory movement of the shaft H, as heretofore described.

Springs I maybe applied to the locking bars 62 to normally urge them into locking relation with the bars E and F, when the line guide structure D is'in raised position.

In order to secure the skeleton structure in angularly adjusted position with reference to the center of the bar 18, as an axis, a lever I 05 is pivoted at. I06 to the outer surface of the side member 1, and is' provided with a curved end I01 shaped to conform to the projecting end of bar I8. A trigger I08 is pivoted at I08 to the member I and is arranged with a cam shaped end IIO against the lever I05 in position to move its curved end I01 into tight frictional contact with the bar I8.

The hinged member 84 is provided to hold a stenographers note book in place. When a book is inserted to be read without spacing the book as the shorthandnotations are typed, the book is held between the two rollers and the pages to be typed hang outside of the member 84. When the book is to be spaced, line for line, it is held between the rollers, with the pages to be copied behind the member 84, the latter serving as a line guide. When the book is not to be spaced, the roller 8 remains inactive. When the book is to be spaced, the roller 9 is spaced by actuation of the

levers

53, 58, and 58.
