LASTING-STRIR Original application filed December 2, 1909, Serial No. 530,928.

Specification of Letters Patent.

1912. Serial No. 694,838.

To all 107.- can it may concern:

Be it known that I, VVJLLIAM. B. Karonnni', a citizen of the United States, residing in Vineland, New Jersey, have invented certain Improvements in Lasting-Strips, (being a division of application Serial No. 530,928, filed December .2, 1909,) of which the following is a specification.

One object of my invention is to provide improved means for temporarily attaching the upper to the insole of a shoe, which means shall be capable of being bentv to conform to the outline of the part to which it is applied, and which shall be free from the objections characterizing the tacks customarily used for the same purpose.

It is zlso desired that the particular last ing stri invented by me shall be of such a construction as to be easily and completely removable after the stitching operation.

These objects and other advantageous ends, I secure as hereinafter set forth, reference being had to the accompanying draw ings, in which,

igure 1 is a perspective view of a portion of one form of the flexible strip constituting my invention; Fig. 2 is a perspective view of the stamping from which the strip shown in Fig. 1 made; and Fig. 3 is a perspective view of a special form of lasting strip.

in the above drawings my improved lasting strip is shown as consisting of a body of flexible strip material, such as thin steel ribbon, formed as indicated in Fig. 2, of an elongated stamping having a series of substantially semi-circular or other suitably formed indentations or scallops 1 along one of its edges, between each of which is a relatively sharp point 2. The opposite edge of the strip is usually formed with a series of semi-circular projections, each preferably opposite one of the recesses l, and it will be noted that the construction shown is uch as to permit of the 'fOl'D'ltttlOll of a number of strips from a sheet of the material without any loss thereof, the recesses being complementary to the projections 3. Said strip is then formed by suitable machinery so that its body portion, which consists of the projections 3, lies in a plane substantially at right angles to that containing the points 2, so that owing to the peculiar forl mation notcd,as well asto the thinness of the material, this strip is extremely flexible.

llndcr conditions of use the lasting strip is mounted around the ed e of an insole after this with the upper oi: a shoe has been mounted upon a. suitably supported last, said strip being fastened by pitch or other suitable adhesive to the between substance in the case of welt insoles and turn soles, or near the edge of the insole in the case of McKay insoles. It is of course obvious that the lasting strip may be held by tacks, line wire or staples passing through holes provided for the purpose, or it, may itself be provided with any desired form of integral projections i; as shown in Fig. 3. Such projections are preferably in the form of punched out tongues extending at right angles to the plane of the semi-circular projections 3.

.\l'tcr the lasting strip has been applied to the insole as above noted, the edges of the uppc' are drawn over the edge of the insole and are caught or hooked on the projccting points 2 of said strip. The shoe is then sewed to permanently connect the insole andv upper, either with or without a welt, as the case may be, after which the flexible metal strip may be removed and again used or discarded as desired, though in certain cases it may be allowed to remain in position. under which conditions its points would properly be turned down.

While the tongues 4- of that. form of the invention shown in Fig. b firmly hold the flexible strip to the leather of the insole, they are of such a nature as to permit of said strip being easily removed it this should be desired after the stitching operation has been pcrfornuul. in any case the strip is of such a nature that it is relatively flexible both in the plane of its body portion and also in a plane at right angles thereto, so that it is not only suited for use as above described, but may be conveniently wound upon and supplied from reels or roll -onc of the essential features of the invention being the provision of a strip which may be bent. to follow the edge of an insole and which may be suitably fastened thereto. It should also he possessed of some means for engaging and holding an upper and be of such nature that it may be removed after the upper is sewed to the insole if this be desirable.

I claim 1. A new article of manufacture consisting of a flexible lasting strip having one edge formed in a series of projections and its other edge formed with recesses complementary to said projections, the metal bet-ween the recesses being formed to constitute holding points.

2. As a new article of manufacture, a last ing strip consisting of a body portion formed of a number of connected metal scallops, and an integral holding portion consisting of a series of points extending substantially at right angles to the plane of said body portion.
