COPYHOLDER Filed pt. 7, 1926 2 Sheets-Sheet 1 June 9, 1931.

w. WOLF GOPYHOLDE'R Filed Sept. 7, 1926 2 Sheets-Sheet 2 INVENTOR W250 171/0 BY J Patented June 9, 1931 UNITED STATES PA-TENT oFFicE I WILLIAM ROY WOLF, OF ROCHESTER, NEW YORK, ASSIGNOR, BY ME SNE ASSIGNMENTS, :51 TO REMINGTON RAND INQ, OF BUFFALO, NEW YORK, A CORPORATION OF DELA- WARE oorxnornnn Application filed September This invention relates to copy holders of a type adapted for use in connection with typewriting machines, adding machines, billing machines, and the like, and has for an object to provide an improved holder which may be readily and easily applied to such machines without changes in their design or construction; which may be attached thereto or detached therefrom in a simple manner and without the use of tools; which when so supported or attached will be supported in a position convenient for inspection of the copy, and which will be relatively simple and inexpensive.

Various other objects and advantages will be apparent from the following description of an embodiment of the invention, and the novel features will be particularly pointed out hereinafter in connection with the appended claims. 1

In the accompanying drawings:

Fig. 1 is a side elevation of a book typewriter, to which has been attached a copy holder constructed in accordance with this invention;

Fig. 2 is a front elevation of the improved copy holder detached from the typewriter;

Fig. 3 is a rear elevation of the same;

Fig. 4 is a sectional plan of the copy holder and a portion of the typewriter to which it is directly attached, the section being taken approximately along the line l4 of Fig. 2;

Fig. 5 is an elevation through one of the arms and brackets of the same;

Fig. 6 is a sectional plan of the same, with the section taken approximately along the line 66 of Fig. 5;

Fig. 7 is a perspective of one of the brackets; and

Fig. 8 is an elevation of one of the bearings for the operating lever.

In the illustrated embodiment of the invention, thecopy holder is constructed for at tachment to a typewriter of the book or flat platen type. Such a typewriter includes a 7,: 1926. Serial No. 133,931.

1, that is, from side to side, and upon the frame 2 for letter spacing. The carriage 3 supports the usual keys t and type bars for printing upon a suitable sheet supported upon the base 1, as usual in such machines.

The frame 2 at a point rearwardly of the carriage 3 is provided with posts 5 which are reinforced by webs 6. These posts 5 at opposite sides of the frame are provided for supporting the tabulator stop bars or other parts of the typewriter mechanism, and travel a forwardly and rearwardly upon the base 1, but do not move laterally with the carriage 3. The details thus explained are those usual in typewriters of this type, and do not form a part of the present invention The improvedcopy holder may include a back section 7, and a front or face section 8 which is mounted for vertical adjustment upon the back section. Such vertical adjustment is controlled by a link or rod 9 which is connected to a lever 10, the latter being pivoted at 11 to the back section 7. A spring 12 is connected between a struck out tongue of the back section and the lever 10 for normally urging the lever downwardly. A bar 13 of metal, such as a metal ribbon, extends across the back face of the back section 7 and is secured thereto in any suitable manner such as by screws or bolts 14.

' The ends of the bar or ribbon 13 extend forwardly as arms from the sides of the back section, and then parallel to the back section and away from one another as shown particularly in Fig. 4. Brackets 15, shown separately in Fig. 7, are secured tothese parallel or free ends of the arms of strip 13, so as to extend further forwardly therefrom. Such brackets 15 may be formed of stamped sheet metal and have a forwardly extending tongue 16, bent angularly at its extreme free end to form 3, depending hook 17. Flanges 18 from the sides of each bracket are bent forwardly along the side edges of the tongue 16, but terminate short of the hook 17.

The brackets 15 may be secured to the arms of the strip 13 in any suitable manner, such as by screws 19 which pass through apertures in the arms and have threaded engagement with the rear Wall of the brackets, as shown particularly in Figs. 5 and 6. The tongue 16 of each bracket is hookedover one of the posts 5 or a. bar of the frame 2 of the typewriter, as shown in Figs. 1 and 5, and the side flanges 18 may embrace the webs 6 extending from the same posts 5, so as to prevent movement of the bracket horizontally upon the post. The brackets are, therefore, movable into and out of engagement with the posts solely by a vertical movement.

Hook shaped bolts'20 pass through suitable apertures 21 in thefree ends of the arms of strip 13, adjacent the points of attachment of the brackets 15. The hook ends 22'of the bolts 20, hook around the posts 5vhorizontally,and the opposite ends may have threaded thereon suitable wing nuts 28, so that by operation of the wing nuts, the hook bolts 20 may be drawn tightly against the posts 5, and thus lock the brackets 15 firmly thereto. In some. instances the posts 5 may have undercut ledges 2 1, and in that event the hook bolts will engage beneath the ledges as shown in Figs. 1 and 5. The hook end of each bolt may have a. strip of rubber tubing 25 thereover, so as to prevent marring of the finish of the typewriter posts, and to provide a somewhat yielding contact when the bolts are drawn tightly around the posts.

Strips or bars 26 may be secured to the bar 13 on opposite sides of the bracket 15, such bars being twisted through 90 so as to form bearing supports for an operating shaft 27. Such bars 26 may have lateral slots 28 adjacent their free ends, for receiving the shaft 27, and the latter is secured in such slots by plates 29 which are secured face to face with the slotted ends ofthe strips or bars 26, such as by screws 30. The plates 29 may also be provided with lateral notches or slots 31 which receive the shaft 27 from the reverse direction, soas to effectively confine the shaft 27 within the slots 28. The shaft 27, after passing through the bearings provided in the straps or bars 26, has a rear wardly extending arm 32, and at its other end a forwardly extending arm 33. The forwardly extending arm 33 serves as a convenient handle or lever arm, by which the shaft 27 may be rocked. v

The free end of the rearwardly extending arm 32 of the shaft 27, is pivotally connected by a pin34 to a link 35, the latter being in turn pivotally connected by a pin 36 to the free end of the lever 10, so that when the forwardly extending arm 33 is depressed the lever 10 and the link will be elevated against the action of the spring 12, to raise the front face 8 of the copy holder. The spring 12 serves to return the lever 10 and the shaft 27 to the normal position when released. The details of the control of the front face section 8 of the copy holder by the lever 10 are well known in the art and, therefore, a specific description of them is omitted in the interest of clarity, since those details per se form no part of the present invention.

Fromthe foregoing it will be obvious that such a copy holder may be easily and quickly attached to, or detached from, typewriters and the like, without changing the construction of the typewriter or machine to which it is attached, and without the use of tools. A copy holder thus supported will be positioned immediately in the rearof the typewriter and move therewith in line spacing, so as to be disposed in a position convenient for inspection of the copy at all times. The parts by which the holder is attached are largely formed of bent wire or rods,and of stamped sheet metal, and, therefore, will be relatively inexpensive. V

Itwill be obvious that various changes in the various details, which have been herein described and illustrated in order to explain the nature of the invention, may be made by those skilled in the art within the principle and scope-of the invention as expressed in the appended claims. p l p I claim as my invention: 1 p 1 1.
