Application July 20, 1928. Serial No. 294,165

16 Claims.

This invention relates to certain new and useful improvements in copyholders, and more particularly to a device for holding and displaying in a convenient position for transcribing the notes thereon, a strip of paper such as is used in a stenotype machine or similar stenographic typewriting machine. It also relates to means for advancing the sheet through the mechanism so as to expose the notes to be transcribed in certain 10 predetermined positons on the copyholder.

In a stenotype machine, the stenographic notes are mechanically written in a continuous column of Words or phrases on a long, comparatively narrow, strip of paper. When the notes are transcribed, this strip should be held in a substantially upright position and advanced upwardly at frequent intervals in order to bring new portions of the notes into view. The paper strip is often quite long and is usually folded into a stack of alternately directed folds, or rolled on spools or cylinders, so that it is diflicult when using an ordinary stand or copyholder to successively expose the different portions of the notes to view without frequent handling of the strip andgreat loss of time.

The principal object of the present invention is to provide an improved copyholder, such as is briefly referred to above, and disclosed more in detail in the description which follows, which will conveniently hold and display the strip of notes, and which is adapted to advance the strip by predetermined'steps with little effort-on the part of the operator. The device is so arranged that the typists hands always remain close to the typewriter keys, and a single impulse imparted to an operating key or lever sufiices to advance the strip a pre-determined distance.

One object of the invention is to provide simple and easily operated means for advancing the sheet through the. copyholder and ejecting it therefrom, without the necessity of previously rolling the strip on spools or other devices.

Another object is to provide means for moving Another object is to provide a copyholder in which the strip may be quickly reversed or turned over so that notes on either side of the strip may be transcribed.

Another object is to provide a device of this type which may be quickly erected for'use, or

6G folded into a small and compact form so'that it will occupy very little space when stored away or when carried in a traveling bag.

Another object is to provide a device which is simple, consists of very few parts, and is readily assembled, so that it is economical of manufacture.

Another object is to provide a copyholder of this type capable of supporting and displaying ordinary sheets of paper, books, or other matter to be copied, it being immaterial when so used whether a strip of stenotype paper is positioned in the machine or not.

Another object is the provision of a copyholder in which the strip of notes remains stationary while the notes are being transcribed, thus eliminating blurring of notes, and which is shifted from one pie-determined position on the display stand to another at eachoperation of the shifting key or lever so that the position of the notes to be "transcribed is always known with certainty by the operator.

Other objects and advantages of this invention will be more apparentfrom the following de-.

tailed description of one approved form of apparatus involving the principles of this invention. In the accompanying drawings: Fig. 1 is a perspective view of the assembled device when in use..

Fig. 2 is a vertical section, taken on the line 2-2 of Fig. 1.

Fig. 3 is a side elevation of the copyholder when not in use'and folded for'storage purpose Fig. 4 is a section, on an enlarged scale, substantially on the line 4-4 of Fig. 2. I

Fig. 5 is a transverse section, taken substan tially on the line 5--5 of Fig. l.

substantially taken Fig. 6 is an end elevation of the ratchet mech anism and friction retarder, the view being take substantially on the line 6-6 of Fig 4.

The supporting frame consists of a front dis play panel A, a casing B supported at theupper end of panel A, a base plate C, and a rear panel D pivotally connecting the rear end of base C with the casing B.

The casing B, which may be built up of suitable metal parts or made'in the form of a single casting, comprises side plates 1 and 2, connected at their lower ends by a transverse web 3. front wall portion land'a similar parallel rear wall 5 project downwardly from the web 3 and the lower ends of side walls 1 and 2. v I A transverse top member 6, made preferably of arcuate cross'section as shown," connects thev u per ends of the side wallsl and 2. A substan- .tially vertical web '7 extends inwardly from the,

central portion of side wall 1 and connects the top 6 with the lower web 3.

more'fully described, and also serves to strengthen the sidewall 1 which supports the upper por- I This" web 7 serves as a guidefor the. sliding rack 8, hereinafter tion of the casing. The side wall 2 is slotted from front to rear at 9 so as to divide this wall into a lower portion 10 and an upper portion 11, for reasons hereinafter described. a

The front display panel A, which is adapted to support that portion of the paper strip from which the notes are to be transcribed, is conveniently formed of a flat sheet metal member strengthened by rearwardly projecting side flanges 12. The upper end of panel A is secured to the front wall 4 of casing 13 by means of screws 13 or other equivalent fastening means. The lower end of panel A is slotted or cut away as indicated at 14 to provide an opening extending through the lower end of the panel and slightly widerthan the paper strip, indicated at 15. A pair of clips or guide members 16, secured to the panel A somewhat above the opening 14, project toward one another so as to overlap the edge portions of the paper strip. These guides hold the strip against the face of the panel and prevent lateral movement thereof without interfering with its vertical travel. A pair of similar guides 1'7 are positioned adjacent the upper end of panel A.

At a suitable location adjacent the lower end of panel A the face of the panel is provided with one or more index marks or pointers 18 at either side of the path of strip 15, and a similar pair of index marks 19 is placed adjacent the upper end of the panel. The index marks 18 and 19 are spaced apart the exact distance that the strip will be advanced by each movement of the shift key 53. The mechanism may be so proportioned that this distance will be substantially equal to 100 words of copy, or any other convenient division of the notes to be transcribed. A vertical slot 22 is formed in one of the lower side portions of panel A, through which projects the operating key or lever hereinafter described.

The base C and the rear panel D may conveniently be formed of sheet metal plates, sim ilar to the front panel A, and provided with strengthening side ribs or flanges 23 and 24. The front end of base C is provided with an upwardly extending flange 25 by which the lower end of display panel A is engaged whenthe copyholder is erectedfor use. The rear end of base C is provided with an upwardly projecting flange 26 which ishinged in any convenient manner as indicated at 27 to the lower end of the rear panel D. Rear panel Dis similarly hingedat 28 to the lower end of rear wall 5 of casing 13.

Suitable bosses or legs20 may be stamped from or secured to the bottom of base C for supporting the copyholder on a table or other means of sup ,When the device is not in use, the front panel v A may be detached from base C by slightly lifting the same to disengage its lower end from the lip or flange 25, after which base 0 may be folded in against the rear panel D and the base 0 and panel D are then folded forwardly against the front panel A, as shown in Fig. 3. The aggregate thickness of the panels A, C, and D, and the mechanism mounted on the back of panel A, is

no greater than the thickness of the casing B, so that a very compact assembly of the parts is obtained when. thus folded.

A shaft 29 is rotatably mounted in the side walls 1' and 2 of casing B, above the transverse web 3. Thickened portions or bosses 30 and 31 may be formed on the side walls 1 and 2, in which shaft 29 is journaled. A small pinion 32 is keyed in any convenient manner as indicated at 33 to the shaft 29 adjacent the side wall 1. In a similar manner a ratchet wheel 34 is keyed at 35 to shaft 29 adjacent the side wall 2. The pinion 32 and ratchet wheel 34- serve to hold the shaft 29 against endwisemovement through the bearings 30 and 31. Suitable knobs or handles 36 are secured to the respective ends of shaft 29, at the sides of easing B.

A roller 37 for frictionally engaging the paper strip 15 is freely rotatable on shaft 29 between the pinion and ratchet wheel. This roller may be constructed in any suitable manner, but is here shown as formed of an inner brass tube 38 journaled on the shaft 29 and metallic end discs 39 and 40 secured to the ends of tube 38 and carrying a hollow spool 41, formed of wood or other suitable material. A tubular soft rubber covering 42, for frictionally engaging the paper sheet, is mounted on the outer cylindrical surface of the spool 41. It will be noted that roller 37 resembles in its general construction the platen of a typewriter, although the covering 42 preferably has a relatively soft surface for insuring a strong frictional grip on the paper sheet.

A pawl 43, pivoted at 44 to the end disc 40 of the roller is held yieldably in engagement with the ratchet wheel 34 by means of a suitable spring 45. It will be apparent thatv when the shaft 29 is rotated in a clockwise direction, as seen from the right of Figs. 1 and 2, or in a counter-clockwise direction, as seen in Fig. 6, the ratchet teeth will engage the pawl 43 and cause roller 3'? to rotate with the shaft. However, when the shaft 29 is rotated in the reverse direction, the spring 45 will yield, permitting the pawl 43 to ride over the ratchet teeth so that no rotation of the roller 37 in the reverse direction will take place.

A suitable friction retarder 46, pivoted at one end on the fixed side wall 2, is constantly held in frictional engagement with an out-turned flange 47 on the periphery of disc 40 by the spring 71 interposed between retarder 46 and the web 3. This serves to prevent over-running of the roller 37. when the first rotation of shaft 29 in the counter-clockwise direction (Fig. 6) is suddenly halted, and serves to hold the roller against rotatio'n when shaft 29 is rotated in a clockwise direction.

The rack 8, already referred to, meshes with the pinion 32 and is interposed between the pinion and the web 7 in casing B so as to be constantly held inengagement with the pinion teeth. The rack is guided for vertical. movement in a. slot '72 in web '7 and passes through openings 43' and 49 in the web 3 and top 6 respectively. This rack 8'is formed on the upper portion of a bar 50 projects outwardly through the slot 22 in the alignment with the bar 52 when downward pressure is applied to the key, but thekey may be folded upwardly against the face of panel A when the device is notin use, as shown in Fig. 3. A tension spring 55 is secured at its lower end to the bar extension 52, and is anchored at its upper end to a bracket 56, formed on the inner faceof the front wall 4 of casing B. This spring 55 normally serves to hold the bar 50 and rack 8=in their extreme upper positions, this upward movement being limited by the engagement of the bar extension 52 with theupper end of slot 22. The downward movement of the rack is limited by the engagement of bar extension 52 with th lower end of slot 22.

A substantially U-shaped frame 57, comprising a pair of side lever arms 58 and 59, is pivoted at 60 between the rear upper portions of the side walls 1 and 2 of casing B. A shaft 61, mounted in the forward portions of the levers 58 and 59, (Fig. 4), carries a freely rotatable roller 62 provided with a rubber covering 63 similar to that on the main roller 37. A pair of compression springs 64 and 65 are confined between the respective levers 58 and 59 and the top member 6 of the casing so as to yieldably hold the roller 62 against the roll 37, or against the paper strip 15 when interposed between the rollers. By lifting up on either of the handle extensions 66 provided at the outer ends of the levers 58 and 59, roller 62 may be temporarily lifted out of engagement with the main roller 37, against the resistance of the springs 64 and 65.

A pair of spring clips 67 are secured by screws 13 or in any other suitable manner to the upper portion of panel A, one at either side of the path of the paper strip 15. These clips may be utilized, either singly or together, to hold any loose sheets or papers of copy against the dis-v play panel A.

When the copyholder is to be set up for use, the base C and rear wall D are folded out as shown in Figs. 1 and 2 and the display panel A inserted at its lower end behind the flange 25 on the base. The upper end of the paper strip 15 is passed from the rear through opening 14 in the display panel, then threaded upwardly behind the guides 16 and 17 and inserted between the friction rollers 37 and 62 which may be given a partial rotation to draw the strip between the rollers, either by depressing the key 53 or by turning one of the knobs 36 at the ends of shaft 29. Roller 37 will be rotated" .until the- ;beginning of the copy that is to be transcribed is substantially opposite the index marks 19 at the top of panel A. The operator now transcribes the notes in the usual manner and when he has read to a position substantially opposite thelower. indexes 18 the key 53 will be given a single downward stroke or impulse until the bar 52 engages the bottom of slot 22, at which time the key is.

releasedand will be returned to its initial position by the spring 55. During the downward stroke of the key and rack, the shaft 29 will be be located opposite theupper index marks 19. The operator will now know exactly where to find the notes next to be transcribed and no time will be lost.. The main body of the strip 15 which is to be transcribed (which may be either in the form of a stack of alternately folded sections as shown in the drawings or in the form of a roll), is laid upon the base member 0 between the front and rear panels and will automatically feed itself through the opening 14 and upward between the guides 18 and 19 along the face of display panel A. If desired, an idler roll 69 may be mounted'in panel A, at the upper'edge of opening 14, to facilitate the passage of the paper strip through this opening. If extra long takes, or lengths of paper strip are to be transscribed, the pad or roll of notes may be placed on the floor or table and passed up behind guides 16 instead of being placed on the base panel C. After the strip is ejected from the rear of easing B it may be caught in any suitable receptacle or permitted to fold itself upon the table or floor at the rear of the copyholder.

In case the operator desires to transcribe notes from an intermediate portion of a long strip of copy, it is not necessary to run the entire strip through the device, but the portion of the strip just above that portion which the operator desires to expose to view may be passed sidewise through slot 9 in the side of casing B and between the rollers 37 and 62, the upper roller 62 being elevated to permit the insertion of the strip by lifting up on one or both of the handles 66. The lower end of panel A is raised to permit the lower portion of strip 15 to be passed upwardly through the bottom of opening 14 and the remainder of the strip is laid as before upon the base member C, the lower end of panel A then being returned to its normal position behind the.

flange 25 on the base. The key 53 is now manipulated in the usual manner to advance the strip upwardly by pre-determined steps until the end of the matterto be transcribed is reached, at which time the entire strip may be removed side wise from the machine by a reversal of the oper ations just described.

When a 'stenotypist prints three stars (or other suitable indication of an error), it signifies that the matter immediately. preceding should bechanged to read as rewritten following the stars. Since the display panel A is quite long and displays approximately one hundred words at one time, the danger of copying notes that must subsequently be canceled is greatly dimim' ished.

If the operator desires to use the display stand for holding loose sheets of copy, or other similar matter, the sheets may be inserted under.

the spring clips 67,. ormay be inserted behind the flange 25 of the base and resting against the panel A. If necessary, the key 53 may be folded back against the panel A so as not to interfere with the wider sheets; The copyholdermay be used in this manner without the neces sity of'removing any stenotype strip or roll that is already in place within the holder. If a book is to be supported, the panel A may be moved backto provide a supporting space for the thick erobject between thepanel and flange 25.

When not in use, the device may be quickly collapsed by simply folding in the base. and rear panels, as alreadydescribed, and folding up the key 53. This is but the work of an instant, andthe device may now be stored awayin a drawer or other small receptacle, or easily' ca'rried in .a traveling case;

It will be obvious that eitherside of a strip of notes may be exposed in this copyholder, it being a very simple operation to remove and reverse the strip. 7

Since the various makes of typewriters employ both right and left-hand carriage return levers, the spacing lever or key on the copyholder may be placed on either the right or left side of the front panel. It will be noted that the major portion of the space between the front and rear panels of the copyholders is entirely open and unobstructed so that the copyholder may be positioned closely adjacent either side of the typewriter, with the typewriter carriage projecting between the panels and freely movable in this space. This will bring the notes into the .most convenient position for reading and place the shifting key or lever of the copyholder in a position where it may be operated with a minimum of effort.

The copyholder may be conveniently and eco nomically formed of metal stampings and castings, but it will be apparent that many portions of the device could be formed of wood or other materials. While the rack and pinion mechanism here disclosed is one approved example of a suitable mechanism for imparting rotation to the roller shaft, other forms of gearing such as sprocket chain and sprocket, or a cable and drum could be substituted, and it is to be understood that all such equivalent mechanisms are considered as within the scope of the invention as do- I fined by the following claims.
