F. E. MURPHY COTTON SACK Filed Aug. 20, 1934 Znmntur Patented Dec. 10, 1935 UNE'EED STATES iA'i'ENT OFFICE Application August 20,

2 Claims.

This invention aims to provide a cotton pickers sack which will gap open at the top, making it easy for the picker to put the cotton in the sack, the sack being capable of side-for-side reversal,

and the supporting sling requiring no attention when the reversal is brought about.

Fig. l is a side elevation showing one side of the sack, parts being broken away, Fig. 2 is a side elevation showing the opposite side of the sack, parts being broken away, and Fig. 3 is a section on the line 33 of Fig. l.

The sack I is made of flexible material, is open at the top, closed at the bottom, and made up of walls 2 and 3, which are secured together at their outer edges by longitudinal lines of stitching, shown at The stitchings 4 do not extend to the top of the sack, but terminate at 5, in spaced relation to the top of the sack, thereby forming openings 55) at the sides of the sack, at the top thereof.

The sack tapers a little at the top, as shown at 5 in Fig. 1, and the surplus material thus produced is turned in and stitched at l to the upper outer corners 3B of the respective walls 2 and 3, at opposite sides of the sack, to form reenforcements 8. The ends of a flexible sling 9 are inserted into the top of the sack I, behind the reenfcrcements 8, and are secured to the respective walls 2 and 3, by the stitchings shown at i.

Because the stitchings 4 terminate at 5, in spaced relation to the top of the sack, each of the walls 2 and 3 is provided at its upper end with a triangular flap, the flap of the wall 3 being marked by the numeral ID, and the flap of the wall 2 being marked by the numeral II.

The sling 9 is placed around the neck of the wearer, above one shoulder. The sack I rests against the body of the wearer, below the arm of the opposite shoulder. If the wall 3 is next to the body of the wearer, the flap I remains erected, as in Fig. 1, and its free corner, represented by the corner 20 of the flap II in'Figs. 1 and 3, is secured to the reenforcement 8 of the wall 2 by a detachable and shift-able securing device, such as a safety pin I2.

Under the circumstances last above set forth, the flap I I of the wall 2 is permitted to hang down. This causes the top portion of the wall 2 to sag outwardly, as in Fig. 3, thereby forming a triangular mouth It at the top of the sack, the flap IQ of the wall 3 extending upwardly above the mouth.

The open mouth It, with the raised and secured flap I above it, makes it easier for the operator to put the cotton in the sack i than 1934, Serial No. 740,680

would be the case if he had to introduce the cotton into the sack through a narrow slit formed by two walls of equal height. 7

The edges I5 and I6 of the flap 40, which define the free corner 20 of the flap, are not of the 5 same length. The center of mass of the flap I, therefore, is nearer 'to one longitudinal edge I8 of the sack (Fig. 1) than to the opposite edge iii of the sack. Consequently, the widest part 25 of the mouth I4 is nearer to the forward edge 10 (I8 in Fig. l) of the sack I than to the rear edge (I9 in Fig. 1) of the sack, and the operator does not have to reach back under his arm, in order to put the cotton in the sack. The same observation holds true if the flap II is turned up 15 and secured by the safety pin I2, the flap I0 being turned down: with the qualification that the edge I8 then is the rear edge, and the edge IS the forward edge of the sack I.

When one of the walls 2 and 3 becomes worn, 20 the sack I is reversed, side-for-side, the wall that formerly was the outer wall becoming the inner wall, and the wall that formerly was the inner wall becoming the outer wall, the outermost flap being turned down, and the innermost flap being 25 turned up and secured by the safety pin I2.

Because the detachable and shiftable securing device I2 is used, the operator does not have to bother with snap fasteners or the like, the securing device I2 simply being shifted from the corner 2i] of one flap to the corresponding corner of the other flap. No adjustment of the sling 9 is called for, when the sack I is reversed side-forside, and there is no changing of the ends of the sling 9, with respect to the sack I, by means of 35 snaps and eyes, or otherwise.

By way of summary, the sack (I) may be said to comprise opposed walls (2 and 3), and a sling (9), connected at one end to the upper outer corner (30) of one wall and at its opposite end to the opposite outer corner (30) of the other Wall. The sack (I) has openings (5) in its outer longitudinal edges (I8 and I9), these openings extending downwardly from the upper edge of the sack,

for a limited distance, to form an approximately I triangular flap (III or II) at the upper end of the respective walls (3 andv 2), the flap forming a free corner (20). Either of the flaps (I0 or II) is downwardly foldable along a line (H) extending from the end of the sling (9) at the upper outer corner (30) to the bottom of the opening in the opposite longitudinal edge of the sack. Thereby, the upper portion of thewall (2 in Fig. 1) that has its flap (II) folded, as aforesaid, is caused to bulge outwardly, as in Fig. 3,

and give the sack a normally-open mouth (I 4). The safety pin l2) constitutes means for securing the free corner (20) of the flap (ID or II) of either wall (3 or 2) to the opposite wall, in upstanding relation to the mouth (14) and above the mouth, to form a cotton-directing surface leading to the mouth.

The sack l is further characterized by the fact that the means last above referred to is a single detachable fastener (I 2) which is shiftable at the will of an operator from the free corner (20) of one flap (H!) to the free corner (20) of the other flap (H).

The sack is still further characterized by the fact that the free corner (20) of each flap (I or II) is defined by a top edge (l5) and a side edge ("5), the side edge (l6) being shorter than the top edge (l5), thereby, to bring the center of mass of the downwardly folded flap (I I in Fig. 1) nearer to one outer edge (I8) of the sack than ,to the other longitudinal edge (l9) thereof, and to cause the widest portion (25) of the mouth (M) to be disposed nearer to the outer edge l8 for example), than to the other longitudinal edge (I9).

I claim:

l. A cotton pickers sack comprising opposed Walls, the sack having openings in its outer longitudinal edges, the openings extending downwardly from its upper edge, for a limited distance, and a sling permanently connected at one end to the upper outer comer of one wall and permanently connected at its opposite end to the opposite upper corner of the other wall, the sling cooperating with the openings to form an approximately triangular fiap at the upper end of each wall, each flap having a free corner, either flap being downwardly-foldable along a line extending from the end of the sling at one upper outer corner of the sack to the bottom of the opening in the opposite longitudinal edge of the sack, thereby causing the upper portion of the wall that has its flap folded, as aforesaid, to bulge outwardly and give the sack a normally-open mouth, and means for securing the free corner of theflap of either wall to the opposite wall, in upstanding relation to the mouth, and above the mouth, to form a cotton-directing surface leading to the mouth.

2. The cotton pickers sack of claim 1, wherein the free corner of each flap is defined by a top edge and a side edge, the side edge being shorter than the top edge, thereby to bring the center of mass of the downwardly-folded flap nearer to one outer longitudinal edge of the sack than to the other longitudinal edge thereof, and to cause
