Y SACK BUCKLE Application filed December 31, 1929. `Serial No, 417,778.

This invention relates to cotton pickers sacks and more particularly to a buckle by means of which the straps of the sacks may be readily adjusted.`

With the foregoing and other objects in view, the nature of which will appear as the in the construction, combination and arrangement of parts herenafter fully described and claimed, and illustrated in the accompanying drawings, wherein Figure 1 is a view in side elevation of a cotton pickers sack constructed in accordance with my invention;

Figure 2 is a detail view on an enlarged scale illustrating the manner in which one end of the shoulder strap is connected to the upper end of the sack, these parts and the buckle by which the connection is established being viewed from the inner side;

Figure 3 is a view Y in elevation of the buckle;

Fig. 4 is a sectional View taken on the plane indicated by the line 4 4 of Figure 2;

Figure 5 is a view similar to Figure 2 illustrating the slightly modified form of buckle;

Figure 6 is a View in elevation of the modified form of buckle;

Figure 7 is a sectional view taken on the plane indicated by the line 7-7 of Figure Figure 8 is a view illustrating the manner in which the lower end of the sack is closed.

The cotton pickers sack 1, which may be made of cotton duck or any other suitable material7 is of uniformvwidth throughout its entire length and is provided atv its ends with hems 2 in which are arranged flexible reinforcing members' 3. The sack 1 may be suspended from the cotton picker by either end thereof, and the lower end thereof is gathered together to close the same, as shown in Figure 8. The lower end of the sack 1 is secured in closed condition by a iieXible tie element 4, and the sack is provided with two of these elementsin order to permit either end thereof to be secured in closed condition, the elements being stitched, as at 5, to one side of the sack adjacent the ends thereof.

The shoulder strap 6 is secured at its ends to the upper edge ofthe sack V1 by'buckles- 7 Y which are permanently secured to the shoulder strap and detachably engaged with the sack. The buckles 7 comprise rectangular frames 8, 'and tongues 9 pivoted to theframes by bars 10 which extend across` thev frames near the upper sides of the latter, V`f llieshoulder straps 6 are provided withlooped ends 11 which are engaged withthe upper 'sides of the frames'S. The frames extend' downward- Vly from the ends ofthe shoulder straps 6 and their lower portions are arranged at the outer side of the sack 1. The upper reinforcededges of the sack are looped,as at 12,

and such looped portions extend outwardly through the frames 8. The tonguesQ eXtend downwardly fromthe bars 10 to points below the upper surfaces of the lowerY sides of the frames 8 and engage the4 lower and'inner lateral sides and the ends'of the loopedporvtions 12 of the sack. The looped portions 9a 'of the `tongues9 which surround and pivotally connect the tongues tof the frame bars 10 are substantially equal in length to the frame bars so as to cooperate withfthe' latveral sides of the frames 8 tohold'V the tongues againstendwise movement with relation to the frames. The ends of the tonguesv 9 curve downwardly and inwardly from the v'ends of A the loops 9a to the lower edges ofthe tongues yto eifect the gradual decrease in width of tlietongues and thus permit the passage of the looped portions`12 of itssackbetween thei'ends of the tongues and the lateral sides of the frames 8, The ,lower edges of the tongues 9 are toothed or serrated', as at 13', to enable the tonguesto firmly engage the bottoms of the-'looped portions of the sack.'v

A slightlymodied fo-rm of buckle isV shown in Figures 5to 7. This buckle'li comprises "a frame 15, a tongue 16 formed` integrally with and extending upwardly andoutwardly fromthe lower side of the frame, anda loop 17 formed integrally with theupper side of the frame. The buckle 14 is :secured-tothe shoulder strap 6 by having theflooped end 11 Y of the latter engaged with the loop '17 ofthe former. Theframe 15 extends downwardly from the shoulder strap-6 and is arrangedat loof -the outerside ofthe sack 1, a Yportion lofthe upper edge of the sack being looped, as at 18, and extends forwardly through the frame and is engaged with the tongue 16.

To permit the looped portion 18 of the sack to be carried through the frame 15, the tongue 16 is shorter than the frame and has its ends spaced equally from the ends of the frame. The tongue 16 engages the inner lateral and upper sides and ends of the looped portion 18 of the sack, and to permit it to firmly engage said portion, its upper or free edge is toothed or serrated, as at 19.

From the foregoing description, taken in connection with the accompanying drawings,

it will be understood that the buckles may be employed to connect the shoulder strap to veither end of the sack, and that kthe position of the buckles on the upper edge of the sack may be easily and quickly changed or altered so that,`when the lower end portion of the sack in contact with the ground wears, the sack may be turned to-prevent an unworn portion of said end from contact with the ground, 'to theV end that the sack willbe serviceable until its entire lower end thereof is worn out. When this occurs, the buckles are disengaged from the sack, the sack is inverted,tlie now upper and lower ends of the sack are closed and opened, respectively, and the buckles engaged withthe upper end. The buckles may be again adjusted on the sack until the now lower end thereof is completely worn out, to the end that a sack may be serviceable until -it is completely worn out.

While I have described the principle of the invention, together with the article which I now consider the preferred embodiment thereof, it is to be understood that the article shown is merely illustrative and that sucli changes may be made, when desired, as fall within the scope of the invention as claimed.

VI claim A buckle for connecting a shoulder strap y to a sack, comprising an open frame adapted Vto be lsecured by its top side to the shoulder strap and adapted to have a looped portion of the sack extended therethrough over its bottom side, a bar extending across the frame near the top side thereof, and a tongue having a looped portion surroundingY said bar and substantially equal in length thereto to pivtally connect the tongue to the frame and hold signature.

the tongue against endwise movement with Y relation to the frame, the tongue extending downwardly from the bar to a point below the upper edge of the lower side of the frame I to adapt its lower end to enter the looped portion of the sack and-to hold such portion bent downwardly over the lower side of the f frame,the side edges ofthe tongues curving downwardly and inwardly from the ends of the loop to the lower end of the tongue to permit parts of the looped portion of the sack t0 extend between theside edges of the tongue and the lateral sides of the frame, and the
