It is affurther object'of the invention to provide a method of folding napkins in substantially triangular form leaving an exposed '10 edge of the fold inwardly spaced from the ad acent mar in.

' urther ob ects of the invention will appear from the following description when read in connection with the accompanying i drawings showing illustrative embodiments of'the invention and wherein I Figs. 1, 2,'and 3rep'resent successive steps of one. form of the invention;

Fig. 4 is 'a plan view of a completed fold; Figs. 5 and 6 illustrate a second form and Fig. 7 isa completed fold resulting therefrom; i i p Figs. 8 and 9 represent successive steps in a third form, and

Fig. 10 a'completed fold resulting there- Figs. 11,12,13 represent a fourth form of:

fold and f 'Fig." 14 a completed fold resulting there- 30 from;

Figs. 15,16, and 17 represent successive 's'te s in a fifth form; and

ig. 18 the completed fold resulting therefrom;

i 35 Figs. '19 and 20represent still another form of fold; and a I I Fig. 21 the completed form. of Figs. 19 'and'20. i i .1

As shown in 1 a square napkin is first folded by turning in the corners on lines 22 to 25 inclusive. The sheet with its corners thus turned is then folded along line 26 to the form shown in Fig. 2, thus producing a pentagon having a long base upon line 26 of Fig. 1 and two right angles at 27, 28. The

next step is to fold the pentagon upon a line 29 perpendicular to its long side to produce the form of Fig. 3 comprising asecond penta-. gon with three right angles at 30, 31, and 32,

150 the line 29 of Fig. 4 forming the side between NAPK IN 1930. Serial No. 449,933.

an 'les 30 and 31. The final fold is then provi ed by folding the form of Fig. 3 along lines 33,34extending from a point adjacent the angle 30 to the apices of angles 35, 36 of Fig.3. i 5

By virtue of the fact that lines 33, 34 extend from the points 37, 38 adjacent but spaced from the angle 30, there is provided the edge 39 of the completed fold spaced from but parallel with the edge 40 thereof, the'edge 39 formed by a portion of the line 29 of Figs.2 and3. I

When the resulting fold is packaged, the front napkin of the package resting ina position inverted from that of Fig. 4 upon the base 41 will present the edge 39 tobe grasped by the user as for instance to extract a single 7 fold from a fixture.

In the form of Figs. 5, 6, and 7, three of the corners 42, 43, and 44 are first folded in 79 exactly the manner of Fig. 1, the corner 45 remaining unfolded. The sheet is next folded along a line 46corresponding to. line "26 of Figs. 1 and 2, after which the corner 45 is folded. along line 47 to producea penta- 7r gon similar to that of Fig. 2. From this point onwardly, the procedure is exactly the same as that in Fi 1 to4 inclusive, the pentagon resulting romthe foldingof the corner 45, F ig. 5, being folded. along. a line 48 corresponding to line 29 of Figs. 2 and 3 to produce the form of Fig. 6 after which the form of Fig. 6 is folded along the lines 49, 50 located as are lines 33, 34 of 3 toproduce the final fold of Fig. 7 presenting the edge 51 to be grasped.

In the form of Fig. 8 the sheet is first folded to half-size along llne 52 and the corners 53,

"the'final fold of Fig. 10 presenting the edge 63 for-grasping by the user.

The first step in the formation of the fold of Fig. 11 is similar to that of Fig. 8, the sheet being first folded along line 64 to halfsize. This fold is then folded along the lines 65, 66 from the center 67 of the long edge 68 made up of raw edges of the sheet to the corners 69, 70 at the ends of line 64, the result being the triangle shown in Fig. 12 having the portions of the edges 68 falling at 68, 68 bisecting the angle 67 of the isosceles triangle. The triangle of Fig. 12 is then folded along the lines 69, 70 forming uprights perpendicular to the sides 71, 72 of the triangle to provide the pentagon of Fig. 13 similar to Fig. 3 in outline.

The fold of Fig. 13 is then folded upon lines 7 3, 74; located as are lines 33, 34 of Fig. 3 to produce the final fold of Fig. 14 present ing the edge 75 for grasping by the user.

The form of Fig. 15 is first folded upon a line 76 which is the diagonal of the original square sheet and the corners 77, 78, 7 9 of the triangle thus provided are each folded in to the position shown in Fig. 16 to produce the pentagon of Fig. 16 similar to that of Fig. 2. The fold is then completed exactly as the fold of Fig. 2 by first doubling the pentagon of Fig. 16 on line 80 to produce the fold of Fig.

7 17 which is then folded upon lines 81, 82 to formed pentagon.

provide the fold of Fig. 18 presenting the edge 83 for grasping by the user.

The first step in the form of Figs. 19, 20 is similar to that of Fig. 15. The triangle of Fig. 19 is then folded along line 84 to produce the smaller triangle shown in portion in dash and dot lines in Fig. 20. The corners 85, 86 of the resulting triangle are then folded on lines 87,88 to produce the pentagon of Fig. 20 similar to that of Fig. 3 which is then folded along lines 89, 90 to produce the finished fold of Fig. 21 presenting the edge 91 for grasping.

It will be seen that in every case a pantagon having three right angles and two obtuse angles is produced, which pentagon is then folded from points located at the apices of obtuse angles to points adjacent the intermediate right angle to produce the final substantially triangular fold and that in all forms except those of Figs. 11, 12, and 19, a pentagon having two right angles is produced from which the pentagon with three right angles is formed by folding on a line perpendicular to the center of the long side of the first The resulting fold provides an attractive napkin which may be conveniently dispensed from a fixture as in cafeterias, restaurants, etc.

Minor changes may be made in the physical embodiments of the invention within the scope of the appended claims without debase with the ends of said short sides, said fold formed with a pair of tabs superposed on the body of the fold the free edge of each' of the tabs substantially parallel with and spaced from the adjacent margin of the fold to be readily grasped by a user.

2. The process of folding a substantially s uare sheet to substantially triangular form w ich comprises folding the sheet along one diagonal with each corner of the sheet folded on lines perpendicular to the diagonals of the sheet to produce a pentagon having two right angles, folding the said pentagon along the line of the other diagonal to produce a pentagon having three right and two obtuse angles and folding the last named pentagon on lines extending from the obtuse angles to points adjacent the intermediate right angle to superpose the portions bearing the remaining right angles upon the body of the sheet.

3. The process of folding a sheet to substantially triangular form which comprises folding the sheet to the form of a pentagon having three right angles and two obtuse angles opposite one of said right angles, folding the portions carrying one each of two of the said right angles upon a line extending from the adjacent obtuse angle to a point adjacent the third right angle to'bring the triangular portions carrying the said two right angles into superposed relation with the portion having the third right angle at its point.

4. The process of folding a sheet to substantially triangular form which comprises folding the sheet to a pentagon having two right angles and a long base, folding the thus formed pentagon upon a perpendicular erected at the center of said longside to form a pentagon having three right angles and two obtuse angles opposite one of said right angles, folding the portions carrying one each of two of the said rightangles upon a line extending from the adjacent obtuse angle to a point adjacent the third right angle to bring the triangular portions carrying the said two right angles into superposed relation with the portion having the third right angle at its point.
