Fig. 17 is a section on the line 17 17 of Fig. 2. Fig. 18 is a section on the line 18 18 of Fig. 1.

In the accompanying drawings like reference numerals refer to like parts.

In the drawings reference numeral 1 indicates a base on which the copy holder is mounted and on which the typewriter may also be fastened. This base may be the top of a desk or it may be a board placed on top of the bed of the desk for apurpose that will'presently be described.

Fastened to the base 1 is the pedestal 2, upon which the parts are supported. Pivotally mounted upon the pedestal 2 is the upright 3 which comprises a bracket 4 having a depending lug 5 with a pin 6 thereon which engagessuitable openings in the lugs 7 and 8 of the pedestal 2.

Mounted on the pedestal 2 is'the upright catch 9. Mounted. on the bracket 4 is the screw 10 having a helical compression spring 11 surroundlng 1t. This screw 10 passes through a clip 12 which is yieldingly pressed 7 down upon the base of the bracket 4 by the spring 11. The upright 3 may be placed in a horizontal position, as is shown in Fig.4, and may be raised to a vertical position as shown in Fig. 3, in which position it will look by the engagement between the clip 12 and the upright 9.

Mounted in the pedestal 2 in the lugs 13.

and 14 is the lever 15. Mounted in the pedestal 2 in the lug 16 is the rock shaft 17, on the end of which is fastened the crank 18, as shown in Figs. 3and 4, which crank has a pin 19 thereon, which pin engages with a slot 20 in the lever 15, by which the lever may be rocked by the rocking of the shaft '17. The front end of the shaft 17 is journaled in the lug 21. The front end of the shaft 17 ends in an arm or crank 22 having the sleeve being clamped in place by means of a binding screw 30. The bracket 26 carries a socket 31 in which may be supported a standard for a lamp.

Mounted on the bracket 4 and fastened to the channel 3 is the cylinder 32, which cylinder is shown in vertical section in Fig. 6 and in horizontal section in Fig. 17.

Mounted to slide in the channel 3 is the traveler 33, which traveler has the bracket 34 fastened at the top thereof from which is supported the piston 35, which piston works in'the cylinder 32 for the purpose of forming a pneumatic chuck for the traveler'when it is permitted to fall. The piston 32 is provided with a washer 36 on the bottom thereof, by which the air is compressed in the cylinder. The cylinder is perforated at 37, 38 and 39 for the purpose of permitting the escape of air from the cylinder as'the piston descends, the openings 37, 38 and 39 being small enough to retard'the escapeof the air so as to compel the piston'and the traveler to descend slowly. The bottom of the cylinder 32 below the opening 39 forms an air tight pocket which cushions the piston in its descent and brings it sl'owly'to rest.

The traveler is raised through successive steps and held at the endo-f each step'by mechanism which we will now describe. Mounted to reciprocate in the u'pright 3 is the link 40, which linkat the bottom is turned out and is connected to the lever 15.

. This link passes through the lug 41 which is has fastened thereto the moving cam'plate ary cam plate 50. This cam plate has the two lugs 51 and 52 bent over on the top thereof, which lugs serve as supports for the rollers53 and 54, these lugs serving tolimit the downward movement of 'the rollers. Also struck up on the cam plate are theinclined cam surfaces 55 and 56. Pivotally mounted on the stationary cam plate 50are the levers 57and 58. These levers have the out turned ends 59 and 60 at the inner ends and have the out turned ends 61 and 62 at the outer ends. The outer ends '59 and 60 have their broad surfaces presented vertically and the ends 61 and 62 havetheir broad surfaces extended horizontally. Above the out turned ends 61 and 62 and between the cam surfaces 55 and 56 and the upright 3, are placed the rollers 63 and 64. Near the top of the cam plate 50 is mounted the stud 65 on which is mounted the wire spring 66. The ends of this spring bear on the rollers 63 and 64 and by this spring the rollers are yieldingly held in place against the cams 55 and 56, being supported in such position by the out turned ends 61 and 62 when the traveler 33 is removed. The rollers 53, 54, 63 and 64 each have an annular groove therein to receive the springs 48 and 66 respectively so as to maintain positive engagement therewith.

The traveler 33 is a sheet of metal bent to the form of a channel as shown in cross section in Fig. 17 and'in perspective in Fig. 13. The traveler has the lugs 67 and 68 struck up thereon for the purpose of supporting the platen thereby. The sides of the traveler'33 pass between the sides of the channel 3 and the rollers 53 and'63 on one side and the rollers 54 and 64 on the other side. Theserollers are normally pressed out against the sides of the channel 33, or in other words, they are normally pinched be tween the sides of the channel and the inclined cam'surfaces 44 and 55 on one side and 45 and 56 on the other side, as clearly appearsin Fig. 1 4.

As above explained, the cams 44 and are on the moving cam plate 42 and the cams 55 and 56 are on' the stationary cam plate 50. These various parts form 'a clutch between the moving cam plate 42 and the traveler 33, which clutch operates asfollows: When the button 23is depressed the lever'15 isrocked down at the pin 19 and is raised at the opposite end, carrying up therewith the link 40 and the cam plate 42. This cam plate pinches the rollers 53 and 54 against the traveler 33 by means of the cams 44 and 45, and carries the traveler up therewith. The traveler as it rises passes by the rollers 63 and 64 which are held down by the spring 66, and as soon as the button 23 is released the moving cam plate 42 drops and the rollers 63 and 64 form a clutch that binds the'm'oving traveler 33 in its raised position and holds it there. The moving cam plate 42 drops with the rollers 53 and 54 to take a fresh engagement with the traveler so that the operation of lifting it can be repeated. In this way the traveler is-advanced step by step from the lowest position to the highest position in the limits of its travel.

It is necessary to reset the traveler from any position to'which it may have been elevated, and this resetting of the traveler we 'secure'as'follows: The lug 49 on the moving cam plate 42 normally rests above and out of engagement with the out turned ends 59 and 60. When the button 23 is raised it operates through the train of mechanism to'pull down on the link 40 and the cam plate 42. The lug 49 then engages with the out turned ends 59 and 60 and draws the levers down at their inner ends, causing them to raise an their outer ends, and with them the rollers 63 and 64 are raised, so that they no longer pinch between the cam surfaces 55 and 56 and the sides of the traveler 33. At the same time as the cam plate 42 is drawn down, the cams 44 and 45 move away from the rollers 53 and 54 which are held against following them by reason of the out turned ends 51 and 52 on the stationary plate 50.

This then releases the traveler 33 from the clutch and it is then free to drop by gravity, the rollers being held in their upper posltion in the meantime by the out turned ends 51, 52, 61 and 62.

The position which the parts occupy when the traveler is at rest clutched in elevated. position is shown in Fig. 14. The position which the parts occupy when the clutch is released to permit the dropping of the traveler is shown in Fig. 15. The maximum length of each upward step of the traveler is determined as follows: The downward movement of the'arm 22 is limited by the set screw. 25. The upward movement of it is limited by the moving cam plate 42 which carries the spring 48, which in turn makes contact with the rollers 53 and 54, which rollers are held against downward movement by the out turned supporting plates 51 and 52, which in turn are part of the stationary cam plate that is rigidly supported on the upright 3. The movlng cam plate 42 is thus suspended from the rollers 53,

being free to move up therefrom but being restrained in its downward movement by means of the spring 48. This suspension of the moving cam plate determines the proper position of the button 23 on the arm 22 and the arm 22 and button 23 can be raised above their normal position by drawing down on the link 40 and moving cam plate 42, which in turn flexes the spring 48 as shown in dotted lines in Fig. 15. The spring 48 then fixes the normal upper position of the button 23 and the set screw 25 limits the downward movement thereof, and the contact between the lug 49 and the out turned ends 59 and 60, together with the flexing of the spring 48 limits the extreme downward movement of the cam plate 42 and the extreme upward movement of the button 23. Quick downward movement of the moving cam plate 42 is secured by the spring 69 which is secured to the link 40 at one end and to the upright 3 at the other end. See Fig. 5. The tension of this spring in its normal position is not sufficient however to flex the spring 48 or disturb the position of the cam plate 42. The relation of the parts is such that the upward travel of the link 40 is about seven-tenths of an inch and the platen is advanced through steps of about six-tenths of an inch. Supported on the traveler 33 is the platen 70. Struck up on the traveler are the lugs 67 and 68.

side serves as a guide against the lugs 67 1 and 68 when steering the in engagement therewith.

In Fig. 7 we have shown the platen beplaten 70 to place ing placed in position with the lug 67 against 7 the guide 72, and in Fig. 8 we have shown the platen in its final position with the lug 67 in engagement with the socket 71. The top of the socket is closed with the lip 72, the extended end of which is fastened to the platen. At the side of the socket 71 is the extension 73 against which the platen bears for the purpose of giving a firm, positive bearing between the platen and the traveler to prevent the platen from swinging on the traveler. The socket 71 and extension 73 may be fastened on the platen in any desired manner. At the top of the platen wefprovide the spring pressed wirc upon the. platen. At the top of the platen we provide, pivotally mounted on the margin thereof, a spring pressed finger 82 having the handle .or finger piece 83 thereon. The platen is wound around its margin by the wire 84, on which wire the finger piece 83 is pivotally mounted. Coiled around this wire 84 is the torsion spring 85, one end of which is fastened to the platen and the other end of which bears against the finger piece 83 by which the pointer 82 is normally held in engagement with'the platen.

As shown at the top in Fig. 1, the wire 82 is curved away from the platen at the middle and terminates at its outer end in i .a loop. Near the bottom of the platen is mounted in the same way a spring pressed finger piece 86 having a pointer 87 thereon, which pointer is preferably straight.

The pointers 82 and 87 serve merely as retaining rods to hold the paper in position] The line indicating is preferably done by the pointer 28 which'is mounted on the upright 3 and does not travel with the platen. Mounted on the rear of the platen 70 are the two rollers 88 and 89. On the roller maybe rotated and the paper web 91 drawn to the roller 88 from the roller 89. The platen so equipped may be removed from the traveler and used as a lapboard and copy book combined, the paper exposed on the platen being filled with the stenographers notes or other writing, and the paper then reeled from one roll to the other, exposing a fresh surface as the notes are placed thereon. The paper may then be rewound so as to expose the notes at the beginning, and the platen may be placed upon the traveler, after which the transcribing of the notes upon the typewriter can be begun, the paper being wound forward again as the notes are copied.

A great many typewriters are equipped with roll top desks, so called, and on'account of this and for other reasons it is desirable to have the copy holder so arranged that it can be stored away with the typewriter in connection with which it is used ina comparatively small space. It is also desirable to have the copy holder so arranged that it occupies a comparatively small space in transportation and so that it is easily set up when it is placed in position. For this reason we have arranged the copy holder so that it can be folded up into a comparatively small space, and the special features of the copy holder by which this arrangement is secured we will now describe.

As above described, the upright 3 is pivotally mounted between the lugs 7 and 8 on the pedestal 2 and is held in an upright position by the e'ngagement'between the clip 12 and the upright 9. The platen may be removed from the upright and the upright may be turned down to the horizontal position as indicated in Fig. 4:, and in so doing it is not necessary to reach any part behind the typewriter, all the parts which are essential for this operation being exposed above the typewriter. To facilitate storing away these parts and making them more compact, the bracket 26 is jointed. The bracket 26 includes the part 97 which is rigid with the upright 3 and in which is mounted the bind ing screw 98 on which is pivotally mounted the main part of the bracket 26.

As shown in Fig. 9, the parts are coupled together by the plate 99 which is integral with the main part of the bracket and which has a slot 100 by which it engages the binding screw 98. A washer or bushing 101 is interposed between the knurled'head of the screw 98 and the plate'99. The part 97 and the main part of the bracket 26 have square abutting ends, each of which forms a shoulder for the other and by which the bracket is held firmly in its extended position when the screw 98 is clamped in position.

In using this copy holder in connection with some roll top desks it has been found upright support,

that there is not room enough back of the machine and under the roll top of the desk for the platen and copy holder. For this reason the machine must be set out on the bed of the desk far enough to permit the copy holder with its platen to be set in behind it so as to project ,up in front of the roll top. The machine however in this position would ordinarily interfere with the closing of the desk. Instead therefore of setting the copy holder and the machine directly upon the bed of the desk we have found it desirable to set both the copy holder and the machine upon a board or plate which is then set-on the bed ofthe desk, the board or plate being moved out when the machine and copy holder are in use and being pushed back when it is desirable to close the desk. Such a board is shownin Fig. l. and has a positive sliding engagement with the bedof the desk and is prevented from sliding back by means of the hooks 102 shown atthe'front end of the board in Fig. 1,, which hooks engage with the front end of the bed of the desk when the desk has been closed up.
