This invention relates to an improved lining for molded rubber boots and to the method of manufacturing the same.
The object of the invention is to provide a lining for rubber boots, particularly for molded rubber boots, the lining being of heavy material which cannot be knitted on small tubular knitting machines or which cannot be knitted at all, such as felt and loosely woven material. The lining used in the method hereinafter described, may be knitted in a wide sheet on a flat knitting machine, or may be made from a sheet of any kind of fabric, whether felted, knitted or woven.
The invention consists in the improved lining for rubber boots set forth in the specification and in the method of manufacturing, all as pointed out in the following claims.
Referring to the drawings:
Figure l is a perspective view of a pile of pieces of fabric, from which the linings are to be made, each piece being folded longitudinally thereof and having a single pattern by which they are to be cut placed on top of the pile.
Fig. 2 is a plan view of one of the pieces of folded fabric constituting a lining with certain portions of the cut edges sewed together.
Fig. 3 is a rear elevation of the completed lining or stocking for the rubber boot.
Fig. 4 is an underneath plan of the same.
Fig. 5 is a side elevation of the lining positioned upon an expansible boot tree.
Fig. 6 is a plan view on a reduced scale of a double pattern terminating at its opposite ends in reversely disposed reverse curves.
Like numerals refer to like parts in the several views of the drawings.
In the drawings, 6 is a pile of fabric pieces folded along the line 7 and upon the uppermost folded piece is placed a pattern 8 having a front edge 9 and a rear edge 10, these two edges being joined by a reverse curve 11 and by an inclined line 12. The pattern 8 corresponds to the stocking which it is desired to make and is laid on top of the Serial No. 340,281.
pile of fabric as shown in Fig. 1. The fabric is then out along the lines l1, l0 and 12, preferably by means of an electric knife and the out edges 10 and 11 of each piece of fabric are then sewed together at 18 and 1-;-
respectively, thus completing a lining 15.
The seam 14 extends longitudinally of the sole portion 16 of the lining and preferably midway between the sides thereof. The seam 13 extends vertically throughout the entire lGllgtll of the back of the lining l5 and the upper end 17 of the tubular lining is left open.
After the lining is thus sewed together, it is pulled over an expansible boot tree 18 as illustrated in Figs. 3 and 5. The pieces of fabric 6 must be folded in each case so that the fold will come along the front edge 9 of the lining as shown in F ig. l is important that the seam be sewed up the back.
After the lining is pulled over the boot tree 18 it is then in condition to have a rubber boot built thereon, and subsequently the boot, lining and tree are placed in a mold and the boot is molded with the lining therein.
The advantages of this type of lining are: 1. a saving of about 20% of the cost over the'old type; 2. it enables the use of material for warm lined boots which could not otherwise be used.
It will thus be seen that the method of making the lining hereinbefore described consists in folding the sheet of material on an approximately straight line 9, then severing the two thicknesses of the material folded, along a p edetermined line col. ing of reverse curve 11, one end thereof intersecting the straight line 9, the other end of the reverse curve being joined by an approximately straight line 10 to a line 12 which intersects the first-named straight line 9 and then sewing the cut edges together, except along the line 12, thus providing a tubular article with one edge closed.
If desired the pattern for cutting out the lining blanks may be of the form illustrated in Fig. 6, that is a double pattern 8, wherein the opposite ends of the pattern 8 terminate in reversely disposed reverse curves 19 and 20 and between the two reverse curves an inclined row of perforations 21 is provided in the pattern through which a line dust may be sifted to form a row of dots on the linii blank, and the lining blank is out along 1 line between the reverse curves 19 and 20, thus obtaining two blanks of the contour illustrated in Fig. 2. The lining blanks ending in oppositely disposed reverse curves 19 and 20 are cut in the same manner as hereinbefore described in relation to the use of the single pattern 8.
By the use of this double pattern, practically all waste is eliminated. The contour of the pattern 8 consists of two straight and approximately parallel lines and 25 joined together by the reverse curves 19 and 20.
It will be understood that in cutting the blanks from the pile of blanks by the aid of the pattern 8, the folded blank of material is cutby means of an electric knife along the lines 20, Q5 and 19 and that the blank thus obtained is cut into two blanks by cutting transversely of the double ended blank and along the row of dots referred to, thus obtaining two blanks like that shown in Fig. 2.
In using the pattern 8' illustrated in Fig. 6 the method is the same as described in Figs. 1 to 5 inclusive, except that the predetermined path includes a pair of reverse curves oppositely and rcversely disposed, said path terminating at its opposite ends adjacent to the fold line 24, Fig. 6, and then severing the length of material thus obtained transversely thereof between the reverse curves 19 and 20, and finally sewing the cut edges of the piece thus obtained together for a portion of their length including said reverse curves, thus providing a pair of tubular articles with one end of each article closed.
\Vhile the term sewing has been used in the specification and in some of the claims as a means for attaching the cut portions of the lining together, it is to be understood that the parts may be joined together in any well known manner, such as looping or other suitable manner, without departing from the spirit of this invention.
\Ve claim:
The method of making a lining for a rubber boot which consists in folding a sheet of material on an approximately straight line, then severing the two thicknesses of said material thus folded along a predetermined path including a pair of reverse urves oppositely and reversely disposed, the said path terminating at its opposite ends adjacent said fold line, then severing the length of material thus obtained transversely thereof between said reverse curves and sewing the cut edges of th. pieces thus obtained together for a portion of their length including said reverse curves, thus providing a pair of tubular articles with one end of each closed.
In testimony whereof we have hereunto setour hands.
