3 Claims.

This invention relates to improvements in b'urlap bags, and itconsists of the matters hereinafter described and more particularly pointed out in the appended claims.

.8 The primary object of the invention is to provide a reconditioned bag which is much stronger at its stitched edges than is a new bag and which has a neat and attractive bound edge free from ravellings or frayings and which may be readily produced by machine operation. A

A further object of the invention is'to provide a bag having its marginal edge turned over and bound in place and has its bottom selvage end turned over as a bound rolled edge which readily withstands the wear such as is imposed upon the bottom end of a filled burlap bag.

'Ihe above mentioned objects of the invention,

as well as others, together with the many advantages thereof, will more fully appear as I proceed In the drawing:

Figure 1 is a view in side elevation of a burlap bag embodying my invention and reconditioned in accordance with my invention;

Figure 2 isv a view in elevation on an enlarged scale with respect to Figure 1, of a burlap bag before it is reconditioned in accordance with my invention;

Figure 3 is a view in elevation ofthe lower left hand corner of the bag shown in Fig. 2, after it Ahas been operated upon and reconditioned in accordance with my invention;

Figure 4 is a transverse sectional detail view through the side seam of a bag reconditioned in accordance with my invention as viewed on line 1 -4 of Figure 3;

Figure 5 is a transverse sectional view through 'the bottom seam of a bag reconditioned in ac- 40 cordance with my invention as viewed on line l5'-5 of Figure 3; and

Figure 6 is a view similar to Figure 3 showing the position of the parts comprising` a doubled over fold at the sideof the bag and the rolled edge at the bottom of the bag, together with the bag material at the corner of the bag, as .they appear when bound in place by the overcast stitching which, however, -has been purposely omitted to better show the position of the various portions.

My improved article contemplates the provision of a turned inside out, used burlap bag exposing along one side, the original folded over margins of both walls of the bag and the associated original line of stitching as well as that pqrtion thereof that, passes through the selvage margins at the bottom of the bag.

Beginning at the top end of that side of the bag, having the original folded over margins, .the

frayed and ravelled edge portions of said margins v 'beyond the original line of stitching therein, are

folded over outwardly and back upon the other Vportions of said margins to enclose or cover said in?,r disposed as loops that pass about the outer edge of said folded over portions of said margins so as to bind the same in place.

As the successive folding and stitching operations approach the corner of the bag connecting the said side of the bag with the bottom thereof, 75.'

I cause a transition in seam structureso that those corner parts of the bag material outwardly beyond the line of stitching are both turned over and inward upon the same side of the bag and the line of overcast stitching follows the 8 turning over and inward of said corner portions of the bag material. After the corner of the bag has thus been passed, the selvage portions at the bottom end of the bag outside of the original line of stitching are turned over as a roll in the same direction as the corner portion and as this rollingin of said selvage portions progresses, it is followed up by said line of overcast stitching to bind the same in said rolled condition. l y

'Ihus the seam is started in one corner of the open end of the bag and is finished at the diagonally opposite bottom end corner and this Without a stop to do any hand trimming of the bag material at the corner joining the side and bottom of the bag.

Referring now in detail to that embodimentV of the invention, illustrated in the accompanying drawing: 1 indicates as a whole a used burlap bag which comprises the two side walls 2--2 100 joined together at one side and the bottomv to leave the bag open at the top as in the usual manner. Such a bag as originally made. is produced from a length of burlap having top and bottom selvage margins 3-3 cut from a strip of 105 such burlap and then folded at the middle into two superposed layers that form the bag walls in a finished bag. Before such a folded length of burlap is stitched along one side and the bottom,

a margin of each layer or wall is folded outwardly no margins are indicated at 4 in Figure 2.

lThis folding over of said margins is a hand operation, and after said margins have-been so folded over, the bag is stitched as at 5, beginning at one corner of the bag and following down and along the folded over margins, around the corner o and along the bottom or" the bag.

Said line of stitching which willA be hereinafter referred toas the original line of stitching, passes through four thicknesses of bag material at the Side of the bag and passes through two thicknesses of bag material at the bottom of the bag. In. layingin this line of stitching vit is attempted to lay the same in the median line of the margins and as the bottom end of the bag is approached, said line takes a curved path and passes into the bottom and preferably in the median line ci the selvages 3. After the bag has 'thus been completed, it is turned inside out to position those .portions beyond said line of stitching inside the bag.

.After the bag has been used, and in reconditioning the same in accordance with my invention, the bag is re-turned inside out so that lt is in the condition shown in Figure 2.

Beginning at the open top end of one side of the bag, an edge portion 7 of each margin 4 is turned over outwardly and then back down upon the other portion of said margin and this encloses and covers up the original line of stitching 5 on both sides of the bag.

As the corner 6 of the bag is approached, instead of hand tr i @t the material thereof to make it approximately follow the rounded por-- tion of the original line of stitching 5 as heretofore, these untrirnmed corner portions which constitutes in part, four thicknesses of bag material, are turned over upon one side of the bag as the beginning of a roll. Of course, the overcast stitching follows somewhat closely upon the turning over of said corner portions and this turning over of the bag material continues throughout the bottom end of the bag. In this operation upon the bottom end of the bag, those portions of the selvage 3 of both'side walls of the bag, outwardly beyond the line of original stitching 5, are turned over as a roll as best` shown in Figure 5 so as to coverlup one side vof the line of'stitching 5 but exposing the other sideof said line of stitching. Of course, the `line of overcast stitching follows closely upon thel rolling in of said selvage portions and the straight stitches 8 pass through only the two walls of the bag while the loop stitches 9 pass about the rolled portions to hold the same in place as best shown in Figs. 3 and 5.

It is apparent from the above that I cause a transitionfin the seam structure at the corner of the bag because that portion of the same, along the side of the bag is a folded over double margin, bound in place by the loops of the overcast stitching while the bottom of the bag has a rolled edge bound in place by the loops ofthe overcast stitching.

In Figure 6there is illustrated the doubled over fold at the side of the bag, the rolled edge at the bottom end of the bag and the curled over bag material at the corner 6 of the bag, the stitching 8-9 being purposely omitted to better show the position of said parts and to better illustrate the transition at said corner from one kind of a fold and seam at the side of the bag to another kind of fold and seam at the bottom end of .the bag. In said Figure 6, the original line of stitching is indicated by a dot and dash line 5a. l

The line of overcast stitching mentioned is made continuous and extends from one, top corner of the bag down the side, around the bottom corner oi the same side of the bag and'then across the bottom of the bag to terminate at that bottom corner diagonally opposite the rst mentioned corner. Thus all frayings and ravellings along the side of the bag are turned in as a double fold margin and are then bound in place while the bottom of the bag is made as a rolled .edge enclosed by said overcast line of stitching.

The bagis thereby reinforced and strengthened with protected seams which enhances its appearance and makes it more salable as a re-V conditioned bag and which meets the demand for agood strong burlap bag, tight at its seams and ready for long periods of reuse.

The operations of folding the portions of the marginal parts of the bag walls, as well as producing the overcast stitching may be carried out by a machine especially designed' therefor so that the method described is commercially practical.

While in describing the invention, I have referred in detail to the form, arrangement and construction of the several parts thereof, the same is to be considered merely by way of illustration so that I do not wish to be limited thereto except as may be specifically set forth in the appended claims.

I claim as my inventionzi 1. A reconditioned burlap bag having a side seam and an end seam including an original line of stitching, the side seam comprising marginal portions folded over and outwardly upon opposite sides of the bag and having edge parts folded back upon the other parts of said portions, the

bottom seam including marginal parts both folded back upon the same wall of the bag and the .transition between said side seam and bottom seam occurring at the corner connecting said seams and a line of overcast stitching following about said side and bottom seams and including loop stitches that pass about the edges of said seams and bind the same in place a portion of said line of stitching extending along the side seam and continued along a part of the bottom seam.

2. A bag embodying therein side walls and having a side seam and'anend seam, a marginal portion of each of said wallsI at one side of the bag being reversely folded back to engage thereupon, a line of stitching extending through bothbag walls and associated folded over marginal portion, overcast stitching having looper thread parts .extending around the folds between said bag walls and margins and having needle thread parts arranged inwardly of said line of stitching to complete the'side seam for the bag, said end seam comprising marginal portions at oneend of the bag secured together by said first mentioned line of stitching and both .folded over in the same direction upon one side wall of the bag and overcast stitching securing the last mentioned folded over portions to said walls of the bag said overcast stitching having at least a portion continuous with the stitching of the side seam.

3. A reconditioned burlap bag having a side seam and an end seam including an original line of stitching, the side seam including portions folded upon the body `of the bag and through of said line of overcast stitchingl extending along a part of one of said seams, around said corner and continuing along the entire length of the other of said seams. said overcast stitching including loops that pass about the edge of said part' of said one of said seams. and the entire length of the other of said seams. l
