This invention relates to copy holders and has for its object the provision of anovel devicedesigned to stand upon a cleslnta-ble or the like and so constructed and arranged as to hold copy which may lie-exposed a line at a time to the view of the operator of a typewriter, adding machine or the like, the deice embodying means intended to be located adjacent the keyboard of the machine and depressible to move the copy step by step for bringing the successivelines into view.

Ail-important object of the invention is to provide adevice of this character which is provided with an adjustment whereby the control platen may be caused to move through a greater or less'arc for displaying or bring ing thesuccessivelines into view, depending upon whether 'the copy is written in "single, double or triple space. h

A further object is to providea device of this character which will permit the operator to keep-his or her eyes on the copy without strain or difficulty of any kind owing to the fact that the device may be mounted directly back oi the a typewriter or at either side thereof, if preferrecL-the key being located in such position with respect to the typewriter or adding machine thatjthe copy holder may be operated to bring'an additional line into vieWwithou-t it being necessary for the operator to actually look at -the key, the action of operating the shifting means tor-the holder beingan extremely simple and shortly become almost easy one which will automatic. i V r V A still further object is to provide a readily operable manual adjusting device for moving the copy the slightdista'nce required in case the copy be of a printed 'rather than typewritten character, this same feature being of,

advantage in permittingreadj ustment of the copy to bring the lines thereon-in proper relationto the guide or indicator.

An additional object is to provide a device of this character whiclrwill be simple and inexpensive 1n manufacture, easy to use and operate, positive in action, 'eflicient and durable n service,and a general improvement ntheart.

vantages in view, the invention consists in the detalls of construction and arrangement of parts to be hereinafter more fully de:

scribed and claimed, and illustrated in the accompanying drawings in which:

- Figure l is a-side elevation of the complete device-with a note book holder attached.

Fig. 2 is a side elevation of theintermittent grip device with the platen shaft in section. r I a Fig. 3 is a cross'section along a linebeyond that of Fig. 2; i i p i Referring more particularly to the drawings, I have shown the device as comprising a main frame indicated broadly by the numeral 1, this frame being capable of manufacture-as a singlecasting oras several pieces secured together. This frameincluds upright or side members 2 terminating at their 'lower ends in horizontal'portions 3 having supporting feet 4 thereon preferably padded as by being shod with'rubber'blocks or the like 5. The members 2 are connected by a transverse portion which may '-be integral therewith-or not, as preferred; At the outer sides of the members 2' are spacedsocket or bearing elements 7 arranged in'pairs and with either palr of which may be'connected the note hook holding means.

. The note book holder comprises a preferably rectangular frame 8 of light construcbearing members'T.

'Journaled through the upper ends of the similar material'indicated -16. The upper ends'of the-members 2 are shownas formed with recesses 17 and 18, the lfqrmeri being for coacting with the platen or roller '15. These two rollers act upon thecopy paper and it is 'tion and consisting of any suitable or neces- -members2 is aehaft 14 carrying a platen or large roller 15' covered with rubber or other "the accommodation of the shaft 14 and the latter being'for ithe accomodation of a shaft 19 which'carries a rubber covered roller 20 clear that when either roller is rotated in the proper direction the copy paper will be moved either upwardly or downwardly, as the case may be. The recesses 18 are elongated so that the shaft 19 may move toward or from the platen or roller so as to insure gripping the cop y paper. Springs 21 are mounted on the members 2 and bear against the shaft .19 for urging the roller into close relation to the platen. It should be mentioned that the recesses 17 and 18 are covered or closed by means of plates 22 bolted or otherwise secured upon the upper ends of they members 2, these plates being formed with outwardly projecting lugs 23 for a purpose to be described.

Suitably secured to the upper ends of the members 2 is a paper guide 2% which may actually be formed of sheet metal and which may therelore be of a hollow formation with the ends provided with a taching plates 25 from which project laterally extending inclined lugs 26 for a purpose to be described. The member 2 1 extends above the platen 15 and the plate members 25 at the ends thereof are formed with ears 27 which are apertured to form bearings for a U-shaped frame member 28 which is pivoted thereto and which carries rollers 29 coacting with the platen for holding the upper end of the copy paper and preventing it from falling forwardly over the exposed copy thereby preventing obstruction of the operators view. T he weight of this member 28 and the rollers thereon should sufiice to hold the paper down wit out it being necessary to provide springs, though if springs are preferable I reserve the right to employ them. The above described lugs 26 constitute stops against which the arms of the member 28 rest when this member is swung upwardly and forwardly.

The numeral 30 designates the forward guide or line indicator which may be formed from a single piece of sheet metal and which is provided at its ends with wings or cars apertured for the passage of the shaft 19 and formed with laterally extending lugs 33 which rest upon the tops of the members 22. Of course, the copy paper in addition to passing between the platen 15 and roller 20 must pass between the guides 2st and 30 as indicated by short dash lines in Figure 2.

At one side of the machine the shaft 1 1 car-- ries a ratchet 3 1, a few of the teeth of which are exposed through an opening 35 in a drum or shell 36 which is rotatably mounted upon the shaft 14: and which is provided with a haudle 37 whereby it may be shifted to a limited extent for bringing a selected one of a plurality of notches 38 into engagement with the laterally ext-ended end 39 of a keeper spring 40 mounted'on the frame 2. At the ends of the series of notches 38 are stop lugs 41 which will limit rotary adjustment of the shell 36 in both directions. Qbviously, the

position of the opening will determine the degree of movement of the ratchet and conscquently the platen when the ratchet is can gaged by an operating pawl 412 which is pivoted at 13 upon an arm 14; rotatably mounted on the shaft 1 1. A spring 45 is connected with the arm and pawl for normally holding the latter in operative relation to the shell, the opening therein, and the ratchet teeth exposed at the opening.

The control means or operating means for the device comprises an elongated lever 16 pivoted intermediate its ends at 17 on one of the frame members 2 and terminating at its forward end in a key -18 located within convenient reach of the operator so as to be readily depressed whenever it is necessary to bring another line of copy into view above the guide or indicator 30. At its rear end the lever 16 is pivotally connected at 19 with the lower end of a vertically slidably mounted rod which has its upper end pivotally connected with the arm 44 and pawl 12 at the point 43. The lever 16 is normally maintained in potential vposition by a coil spring 51 which abuts against a collar 52 on the rod 50 and against a rigid abutment 53 on one frame member 2.

Secured upon one end of the shaft 19 is a segmental gear 54 with which meshes a segmental gear 55 having an elongated handle 56 thereon, the purpose being that by grasping the handle 56 and thereby turning the gear55 the gear 5 1 will be correspondingly turned for rotating the roller 20 to a limited extent so that the copy paper may be moved to a very slight extent if desired or to a slight ly greater extent than is effected by actuation by means of the key, it being consequently possible to readjust in case of non-alinement of the copy with the guide 30. It should also be mentioned that one end of the shaft 14 carries a knob by means of which the platen may be freely turned for feeding the copy when it is first inserted and before the line by line mechanism is brought into play.

In the operation of the device, the copy is inserted from underneath between the platen 15 and roller 20 and the handle or knob is turned to bring the copy upwardly between the guides 30 and 2 1 into such position that the topmost line will be exposed above the former. It is of course understood that the shell 36 must be shifted, by means of the lever 37 to bring the opening 35 at the proper position with respect to the pawl d2, this adjust ment depending upon whether the copy is in single, double or triple space. If the ratchet teeth do not match up with the lines of the copy readjustment may be made by moving the lever or handle 56 so that the roller 20 will move the copy independently of movement of the platen. The operator then copies the line exposed or does what other manipulations are necessary, and upon conclusion of the copying ot-the line it is intended that the key 48 be depressed whereupon the rod 50 will move upwardly and cause the; pawl 42 to engage the ratchet teeth and rotate the platen to a sufficient extent that the next line of copy will bebrought into View above the I guide or indicator 30. V The key 48 is def pressed at the end-t every line until the entire copy has been moved between the platen 710 and roller. The various details of adjustment and the like have already been explained and it is believed that a repetition thereof will be unnecessary. It is thought that the construction, operation and advantages will be readily apparent to one skilled in the art without further explanation.

WVhile I have shown and'described the preferred embodiment of the invention, it should be understood that I reserve the right g to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims. 7

Having thus described the invention, I
