COPY HOLDER OOPYI-IOLDER.

Application filed August 18, 1922. Serial No. 582,677.

To all whom it may concern:

Be it known that I, WALTER A. HOMAN, a citizen of theUnited States, residing at the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Copyholders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to copy holders of p the type employed in connection. with typewriters.

It is well known that it is necessary for efficient typewriting to have some means of holding the copy where it can be conveniently seen. Many different kinds of copy I holders have been invented and offered for sale,'and yet it is obvious that very few of them are in use, which would indicate that the present copy holders are defective-in some important particular.

It is the object of this invention to produce a copy holder that shall be free from most of the serious faults of those heretofore employed. It is evident that the copy to be followed should be held in such a position that the operators head and eyes need not constantly be shifted in order to see the copy and to observe the workings of the machine. It is also very important that the copy shall be supported in such a position with respect to the machine that the focus of the eyes need not be appreciably changed when shifting from the copy to the machine, and vise versa. It is the object of this invention to devise a copy holder that shall embody both of the characteristics referred to above and which shallat the same time permit the copy to be conveniently placed therein and removed therefrom; which shall permit a new page of copy to be quickly and conveniently exposed, and which shall be of simple design and neat appearance. The above advantages, and others which will appear as the description proceeds, are obtained by means of a construction which I will now describe, reference being had for this purpose to the accompanying drawing, 1n which I r V Fig. 1 shows a front elevation of a typewr1terequ1pped with my improved copy holder;

Ijig. 2 shows a side elevation of a typewriter equipped with my copy holder; Fig. 3 is a broken side elevation of a portionof my copy holder;

Fig. 5 is a front elevation of a modification; and

Fig. 6 is an end elevation of the form shown in Fig. 5,

Numeral 1 represents a typewriter of well known make having a keyboard 2 and a platen 3. To one of the sides 4 of the typewriter framework I secure a copy holder supporting bracket, which consists of a clamping member 5 provided with a set screw 6. To the bottom of the clamp 5 I secure a base member 7,,to the outer end of. which I fasten a vertical tubular member 8, which is adapted to receive the vertical portion 9 of the copy holder sup A screw 11 passes porting member 10. through the tubular member 8 and serves as a stop orsupport for the end. of the vertical'member 9. A plurality of holes 12 may be provided, if desired, so that the height of the holder can be adjusted to fit any type of typewriting machine. Rotatably and slidably connected to the supporting member 10 is a cylindrical copy holding member which consists of a cylinder 13 having opposed end members 14: soldered or otherwise secured thereto. A tubular member 15 extends axially through the cylinder 13 and serves as a bearing for co-operating with the rod 10. The cylinder 13 is provided near each end thereof with two angularly spaced openings 16 for a purpose which will hereinafter appear. Cylinder 153 is of such a diameter that the circumference thereof exceeds the length of the paper which is to be secured thereto. For the purpose of holding the copy in place on the cylinder, I provide two clamping members 17 and 18 which are arcuate'in-cross section and have end portions 19 which extend inwardly through the slots 16. To the ends of the inwardly extending portions 19 I con- When the copy 23 is to be secured to the cylinder, the lower edge of clamping memher 18 is raised from the surface of the cylinder and the 'upper edge of the copy in serted therebetween. The lower end of the copy is then wrapped around the cylinder and clamped beneath the upper edge of clamping member 17 in the manner clearly indicated in Figs. 2-and Clampingmember 17 is provided with a cutout portion 24, into whichthe thumb can be inserted whenever a new page is to be exposed. Pivotally connected to the supporting rod 10 are two plate-like members 25, which have a portion 26 thereof extending beyond the outer circumference of the cylinder. These projecting ends are connected by a bar 27 which serves as an indicator or guide. In order to prevent the plates 25 from rotating with the cylinder and also 7 for the purpose of moving the same on the rod 10 in accordance with the movement of the carriage and laten 3, I secure to or form integral with the plates 25 downwardly extending arms 28,

which are provided at their lower ends with a slot 29, which engages the platen bearing 30 just inside of the knobs 31. Arms 28 are either made entirely of resilient material and ofsuch thickness that they .yield slightly as the carriage moves, or they may have a resilient portion 32 which yields. The object in makingt-he arms28 yielding is that by this means the intermittent move ment of the carriage will cause a constant movement ofthe copyliolder, for the reason that there is considerable friction between the tube 15 and the rod 10, and that there is considerable inertia inherent in the copy-' holder and therefore it will lag slightly behind the movements ofthe carriage when the arms connecting thetwo are resilient. I consider this to be an important feature of my invention and therefore desire to emphasize it. 7

In Figs. 5 and 6 I have shown a slightly modified embodiment of my invention. In this modified form the plates 25*. are each provided with an outstanding ear 33, to

which is pivotally secured an indicator 34, whose upper edge rests-on the copy and'indicates the line to be copied. I

The. plates 25, instead of having an integral arm 28 connected thereto, have similar arms 28 secured thereto by means of a clamping screw 35. Arms 28, like arms 28,

i,544,4bi

have slots 29 that engage the spindle 30 and are also made resilient in the manner above explained. The object of making arms 28 movable with respect to plates. 25 is to secure a slight adjustment of the level of the indicator 34, as this may be desirable in order to secure the most comfortable ar. rangement. v

' The operation of my device is as follows.

Thecopy 23, is secured in place beneath the each line. of copy, but where a manuscript;

isto be copied, this relation does not necessarily exist. Where the copy is. typewritten, it is desirable that the. copyholder move in unison with the carriage, as by this means the word to be copied will be directly over the ,place where the printing takes place and the operator can see one or the other by merely moving, the .eyesa slight distance up and down. Where the copy isin longhand orv in shorthand, it is not essential that the copy move with the carriage, but as. a rule it causesvno inconvenience and is therefore not objectionable. I wish, at this point, to. call attention to thefactthat since the copy 23-occupies a'position directly above the platen, the distance of the two from the opera-tors eyes is. substantially equal and therefore the eye does not require to change its focus in looking from the one to the other as is invariably necessary wherethe copy is laid on the table or supported to copyholder may then be rotated about the part 9 so as to'be out of theway. Whena page of copyhas been written, the operator merely places his thumb in the cut-out portion 24 and presses slightly on thefinger'22. A page is then. peeled off from the copy and is turned over so as to expose a new page. a

From the above it is apparent that I have produced an improved copyholderthat is so designed that the copy is held ina position directly over theplaten so that the dis-' tance to-either is so nearly equal that the eye will not have to change its focus as the operator looks from one to the other. My

improved copyholder is also constructed so that it moves with the carriage and has means whereby the intermittent motion of the latter produces a continuous movement of the former. My copyholder can be quickly and conveniently moved out of the way and is so designed that the copy may be easily and quickly shifted so as to present a new page.

Having now described my invention, what I claim is:

1. A copyholder comprising a cylindrical member having a pair of clamping members secured thereto a horizontal suaaortine' 7 a member, means for slidably and rotatably securing the cylindrical member thereto, and means for permtting the supporting member to be rotated about a vertical axis.

2. A copyholder comprising, in combination, a cylindrical copyholding member, means for securing the copy tothe outside thereof, and means for slidably and rotatably supporting said copyholding member.

3. A copyholder comprising, in combination, a cylindrical copyholding member, means for securing the copy to the outside thereof, and means for slidably and rotatably supporting said copyholding member, and means for permitting said copyholder to be rotated about a vertical axis.

4. In combination, a typewriter having a movable carriege, a copyholder, means for slidably and rotatably supporting said copyholder in operative relation to the typewriter, and means connected to said holder and engaging said carriage whereby the movements oi the latter will cause a corre sponding movement of the former.

5. In combination, a typewriter having a movable carriage, a copyholder, means for slidably and rotatably supporting said copyholder in operative relation to the type writer, and means connected to said holder and engagaing said carriage whereby the movements of the latter will cause a corresponding movement of the former, said means being resilient whereby the inter- 'mittent movements of the carriage will cause a substantially uniform movement of the latter.

6. In combination, a typewriter having a movable carriage, a bracket secured to the typewriter, a horizontal bearing member secured to the bracket by means which permit the bearing member to rotate in a horizontal plane, a cylindrical copy holding member rotatably and slidably secured to said bearing member, and resilient means for causing said copy holder to move in accordance with the movement of the carriage.

7. A copy-holding member comprising a bearing member, a cylindrical copy-holder slidably and rotatably secured thereto, a pair of spaced clamping members secured to said cylinder, resilient means for holding said clamping members in place, a plate secured to each end of said cylinder, an indicating member joining said plates, and means secured to said plates and extending to the carriage for transmitting the movement of the latter thereto.

8. A copy-holding member comprising a bearing member, a cylindrical copy-holder slidably and rotatably secured thereto, a pair of spaced clamping members secured to said cylinder, resilient means for holding said clamping members in place, a plate secured to each end of said cylinder, an indicating member'joining said plates, and means secured to said plates and extending to the carriage for transmitting the movement of the latter thereto, said means being adjustable with respeet to the plates.

9. A cylindrical copy-holding member having longitudinal arcuate clamping members secured thereto, and resilient means for securing said clamping members in place, with both edges thereof contacting with the surface of the cylinder.

In testimony whereof I afiix my signature.

WALTER A. HOMAN.
