Application June 26, 1952, Serial No. 295,750

8 Claims. Cl. 197-189) This invention relates to a device for indicatingand gaging the distance of the bottom edge of a work-sheet from the writing line while the sheet is in writing position on the platen of a typewriting machine, and the bottom edge is nearing the writing line.

An object of the present invention is to provide a simple and eflicient device to enable the typist to determine at any moment, as the writing of the sheet is nearing completion, the distance of the bottom edge of the sheet from the writing line on the platen.

Another object of the invention is to provide an indicating and gaging device of this kind which is capable of being used with any of the standard makes of typewriting machines.

A further object is to provide an indicating and gaging device of this kind which is readily attached to and detached from the typewriting machine.

Yet another object is to provide an indicating and gaging device with an uninterrupted and smooth surface over which the work sheet is adapted to guide without possibility of tripping or buckling.

Still another object of the invention is to provide an indicating and gaging device of this kind that when once set needs no further adjustment and has no moving parts to get out of order.

2,744,606 Patented May 8, 1956 In Fig. 1 is illustrated a portion of the top of a typewriting machine including a roller platen 10 mounted on a platen axle 11 journalled in the ends of a platen frame 12. A rod 13 extends between and braces the ends of the frame.

An inclined table or shelf 14 is supported by the frame and extends upwardly from and rearwardly of the platen for supporting and guiding a work-sheet 15 to the platen. The table is positioned in front of the brace rod 13 with its upper curled edge 16 just above the rod.

In standard typewriting machines, a device for gaging the left hand edge of the work-sheet is usually mounted on the machine. In Fig. 1, such a device is shown. This device comprises a body in the form of a narrow plate 17 having a curved or looped end 18 to loosely fit over the curled edge 16 of the paper supporting table 14. A pair of spaced perforated cars 19 extend forwardly from one end of the looped portion 18 for slidably fastening the gage device to the brace rod 13. A flange 20 is formed integrally with one edge of the plate 17 and extends forwardly thereof at right angles thereto for coacting with the left hand edge of the work sheet to indicate and gage the left hand margin of the sheet.

In accordance with the present invention, the gage for the left-hand edge is utilized for detachably mounting the improved indicating and gaging device for the bottom margin. The improved device shown .in Figs. 1 to 5, inclusive, comprises an elongated strip or sheet 21 of card board or other suitable stiff material having a smooth and uninterrupted surface. The bottom of the strip is formed with a hook-like portion 22 separated from the body of the strip by a slot 23 and formed with a lateral extension 24. The body of the strip may be enlarged from a point adjacent the hook-like portion to a point substantially midway between its ends in order to provide an enlarged area 25 over which the sheet is adapted to pass and in order to stiffen the body.

The device is detaehably mounted on the paper supporting table 14 by inserting the extension 24 under the plate 17 of the left hand edge gage and sliding hooked portion 22 underneath the plate, the slot 23 riding over the looped end 18 of the gage and interlocking with said looped end to hold the indicating and gaging device detachably in place, so that it rests on the table 14 and forms a continuation or extension thereof as shown in Fig. 1.

A resilient pad 26, preferably formed of rubber, is suitably fastened to the rear surface of the hook-like portion 22 at a point thereon situated behind the plate 17 of the side edge gage when said portion 22 is mounted in operative position. The pad is triangular in cross-section providing a camming surface 27 which during insertion of the hook-like portion moves said portion into tight clamping engagement with the plate 17 thereby helping to hold the device in operative position.

On the front face of the strip 21, a scale 28 is provided. This scale consists of numbered graduation, successively numbered downwardly at single line intervals to indicate the number of line spaces between the bottom edge of the work sheet and the writing line. When a sheet is inserted around the typewriter platen 10, the leading edge of the work sheet is adjusted relative to the scale so that there are for example thirty-five typing line spaces between the desired writing line on the sheet and the bottom edge of the sheet. If it is determined to have a five line margin at the bottom, the typing will stop when the leading edge of the sheet is moved over the scale into alignment with the number 5 on the scale.

A turned-over finger or lug 29 may be formed integrally with the body along one edge thereof to serve as a guide for the left hand edge'of the work sheet, and keep the sheet in proper alignment.

A reinforcing strip 30 may be fastened across the neck 3 portion 31 of the strip between the body and the hook portion 22in order to provide reinforcement-at this point.

The modification shown in Figs. 6 to 8, inclusive, consists of an elongated strip or plate 32 of cardboard or the like with a scale 28 on-its=face similar to the scale 28 of the form of Fig. l.

The detachable mounting means shown here, however, comprises a plate 33 secured to the bottom end of the strip and forming an extension thereof.

The plate is slotted along one side edge as indicated at 34 andat the said side edge the plate is formedwith a flange 35 extending at right angles to the body of the plate. The flange 35 serves as a guide for the left hand edge of the work sheet. This strip is mounted on a projecting portion of a gage (not shown) for the edge'of -the-.work sheet,-usually associated with the table, by sliding the slotted-portion over said projection.

'In Figs. 9, wand 11, another modification is illustrated which consists of an elongated envelope 36 formed by bendinga strip of paper or other flexiblematerial along -its medial line and folding the bent portions upon each other to form two

side walls

37 and 38. One of the walls may be formed at one end with an extension 39 which is folded over and secured to the adjacent end of the other wall to provide a pocket 40 at one end. The other end of the envelope is open as is the end where the ends of the walls meet, so that the envelope can be slipped over the edge of work-sheet 41 as shown in Fig. 9, with a corner of the work-sheet inserted into the pocket 40, so

as to hold the envelope on the sheet.

The envelope corresponds in length to the length of the work-sheet. The outer surface of one of the walls, for instance, wall 37, is provided with a scale 42 having numbered graduations, successively numbered upwardly, at

single line intervals to indicate the number of line spaces between the bottom edge of the work-sheet and the top edge thereof. The work-sheet is inserted into the typewriting machine with the envelope in place on its edge.

As the typing progresses, the leading edge of the sheet and the envelope with the scale 42 travel upwardly so that the number of lines between the writing line and the bottom edge of the work sheet may be determined at a glance. If a ten-line bottom margin, for example, is desired, the typing will stop when on the scale reaches the writing line.

In Figures 12 and 13 the elongated strip or sheet 41 is similar to the one illustrated in Figure 3. The bottom -of this strip is formed with a hook-like portion 42 separated from the body of the strip by a slot 43 and formed with a lateral extension 44. In this form of the invention,

instead of the enlarged area 25, the enlarged portion is extended in the opposite direction as shown at 45 and the :free edge 46 of this enlarged portion is provided with a paper guiding plate 47 separated from the enlarged area by a spacing strip 48 so that the type work-sheet may be passed between the

members

45 and 47.

On the front face of the strip 41, a scale 49 is provided to indicate the number of line spaces between the bottom eating and gaging the distance of the bottom edge of a work-sheet from the writing line on the platen-of the typewriting machine, comprising an elongated body of cardboard or the like having a smooth surface, a hook-like portion at one end of the body extending in the same plane as the elongated cardboard body for detachable insertion between the shelf and plate part of a typewriting machine, an extension on said portion for insertion under said plate part of the typewriting machine, and a scale on the surface of the body including a column of suecessively numbered graduations.

2. An attachment for indicating the distance of the bottom edge of a work-sheet from the writing line of a typewriting machine, comprising an elongated body of cardboard or the like having a smooth surface, a hook-like portion at one end of the body extending in the same plane as the elongated cardboard body for detachable insertion between the shelf and plate part of a typewriting machine, said hook-like portion having a eamming surface for eamming said hook-like portion into clamping engagement with said plate part of the typewriting machine, and a scale on the surface of the body including a column of successively numbered graduations.
