6 Claims.
ticable for the typist to make corrections on the.
letter sheets while the unitis in the machine, for since all of the sheets are united at the top, access cannot be had to the sheets individually. Some users of this type of snap-out unit have resorted to the expedient of tearing olf the stub, that is,
the part of the sheaf above the weakened lines, while the unit is in the typewriter, so that the letter sheets may be individually turned forward for making erasures. However, in doing this, the
advantage of the snap-out feature is lost, for the carbons are torn off iiush with the letter sheets and must -be individually separated after the unit has been removed from the machine. Other users upon making an error, remove the snap-out unit from the machine, open it up from the bottom, make the erasures at the desk, and are then put to the task of reinserting the snap-out unit in the machine and accurately aligning it before making the correction.
One of the objects of the present invention is to provide a snap-out unit similar to the conventional snap-out units above described, to the extent that the interleaved carbon and letter sheets are united by a glue-line or its equivalent at the top, the letter sheets having coincident weakened lines of severance across the top below the glue-line, and projecting below the carbon sheets at the bottom, normally operated similarly to the conventional snap-out units when there are no erasures to'be made, but having novel features of construction which permit corrections to be made on the letter sheets while the unit is in the typewriter, and thereafter permitting the carbon sheets to be simultaneously separated from the letter sheets.
Other objects of the invention will appear as the following description of a preferred and practical embodiment thereof proceeds. l
In the drawing which accompanies and forms a part of the following specification, and vthroughout the several gures of which the same reference numerals have been employed to denote identical parts:
Figure 1 is a perspective view of a snap-out unit embodying the principles of the invention, al por tion being broken away to show the glue-line;
Figure 2 is a perspective view of the individual sheets of the snap-out unit separated, and lying in parallel planes;
Figure 3 is a. cross-section taken along the line 3 3 of Figure 1;
Figure 4 is a perspective view of the snap-out unit of Figure 1, positioned about the platen of a typewriter, showing the stub partly torn off;
Figure 5 is a view similar to that of Figure 4, after severance of the stub, the sheets being separated for making a. correction;
Figure 6 is a perspective view of a portion of a modified form of snap-out unit, part being broken away to show the glue-line.
Referring now in detail the the several figures, the snap-out unit l is here shown as comprising three sheets, the latter sheets 2 and 3 and the interleaved carbon sheet 4. These sheets are arranged in a sheaf, the sheets being united at the top by a glue-line 5, and the letter sheets being longer than the carbon sheet, so that they extend beyond the carbon sheet at the bottom, as illustrated in Figure 1. Both the letter sheets and carbon sheet are provided with coincident weakened lines 6, 1 and 8, near the top, but belowthe glue-line. These lines of weakness terminate short of at least one of the lateral edges of the sheaf, the point of termination being indicated at 9. The line of weakness 8 of the carbon sheet is more resistant to rupture than the lines of weakness 6 and 1 of the letter sheets.
The letter sheets have congruent cut-outl areas lll above the lines of weakness, extending from a lateral edge of the sheaf to the lpoint of termination of the lines of weakness. The interleaved carbon sheet 4 does not have the cut-out area, but is formed with a slit Il extending from an edge of the sheaf to .said point of termination of the line of weakness, forming a tab I2 which is preferably congruent with the cut-out areas l0, and which is divided from the stub by the slit Il.
While the features above described have been referred only to one side of .the snap-out unit, it is preferred to make both sides identical, adapting the snap-out unit to the convenience of both right-handed and left-handed people.
In using the snap-out unit of the present invention, it is placed in the typewriter and written upon in the usual manner. If there are no corrections to be made, itis removed from the typewriter, the stub grasped'by one hand, the projecting ,ends of the? letter sheets to the exclusion of the carbon sheet being grasped by the other hand and the hands quickly pulled apart, whereupon the letter sheets will become detached from the stub by virtue of the relative ease of rupture of the weakened lines 6 and 1, while the carbon paper will come out intact with the stub', because of the stronger liney of weakness 8. If corrections are to be made, the snap-out unit is not removed from the typewriter at first instance. Instead, the stub which is a composite of the upper end portions of both letter sheets and the interleaved carbon sheet, is torn oil, as indicatedt Figure 4, beginning at the slit which separates the stub from the tab I2. In that form of the invention shown in Figures 1 to 4, in which the cutfout areas extend to the upper edge of the letter sheets, the tearing oil' of the stub completely removesvthe glue-line so that the upper ends of the sheet are now completely detached and may be turned forward individually, permitting corrections to be made. After the sheaf is removed from the typewriter, it is necessary only to take hold of all of the congruent tabs I2., with one hand, and the projecting lower ends of the letter sheets, with the other, and to separate the letter sheets and carbons simultaneously.
Figure 6 shows a form of the invention in which the cut-out areas I3 of the letter sheets do not extend to the top edge of the sheaf, but are conlined to a region below the glue-line. The tabs I4 are congruent with these cut-out areas. This forms a, tab having ends I5 extending to the lateral edges of the sheet, and including the glueline, either of which ends may be grasped to initiate the tearing orf of the stub. i
In order to facilitate rupture of the lines of weaknessiof the letter sheets, when snapping out the carbon sheet in conventional manner, the stub may be provided at any intermediate part with cut-out apertures I6 in the letter sheets, the lower l sides of which coincide with the lines of weakness of the letter sheets intermediate the ends of said lines of weakness. When a, pull is brought upon the stub above the cut-out apertures I6, rupture takes place readily at the points I'l, at which the cut-out aperture I6 intersects the line of weakness.
While I have in the above description disclosed what I believe to be a preferred and practical embodiment of the invention, it will be understood to those skilled in the art that the details of construction and the arrangement of parts as shown and described, is by way of example'and not to be construed as limiting the scope of the invention as defined in the appended claims.
