' SOLE LAYING July 1, 1930.

Patcntecl .luly 1, 1930 P Arr Eur Pic GUY a. conga, or MILWAUKEE, WISCONSIN, assrsnon 'ro UNITED snon MACHINERY CORPORATION, 032 rntrnasomnnw JERSEYLA conronarrron on NEW JERSEY SOLE LAYING Application filed October 4., 1926. Serial 1%. 39,437.
This invention relates to the attachment of soles to shoes and is illustrated herein with reference to the laying of soles in the manufacture of McKay shoes.
In performing the McKay sole laying operation, a channeled and grooved outsole.
is positioned by the operative in the proper relation to the insole and upper of a lasted shoe. The operative then usually presents the work to the nozzle of a staple-inserting machine, inserting a staple at each end of the tip line of the sole, a pair of staples at the ball line, a pair of staples in the shank, and-two or three staplesin .the heel-seat.
' Prior to my invention, it was customary to insert these staples with their bars positioned transversely of the groove, and, accordingly, it has frequently happened that the bars of the staples caught upon the an barb of the needle of the McKay stitcher as the needle was withdrawn from the work during the subsequentv stitching operation. This often resulted in breaking the needle and in breaking or damaging the thread.
2- As the characteristic McKay seam is a chainstitch seam, it is necessary that it be continuous from one end to the other in order to maintain its maximum strength. Accordingly such damage to the thread a) weakens the seamina most undesirable way. It is an object of the present invention to obviate so far as possible the breaking of needles and the damage of the thread in the through-and-through stitching of outsoles to lasted insoles and shoe uppers.
This I have accomplished by positioning such of the staples as are near the line of stitching with their bars upon the shoulder of the groove in which the stitching lies and parallel to the groove instead of transversely of the groove. ples thus positioned, the bars will not catch upon the barb of the needle. If an occaof the stitcher, the staple may be nicked oreven cut in half by the needle, but while the needle is passing into the sole the thread is protected by the barb of the needle, and the bar of the staple is not in a position to With the stasional staple should be positioned so close. to the groove as to be struck by the needle interfere with the withdrawing of the needle. Thus the breakage of needles and damage to the thread are very much reduced.
In its different aspects, my invention comprises both an improved method of manufacturing shoes and a'shoe characterized by the preliminary attachment of a groovedand channeled sole by staples located in the shoulder of the groove and ad'- jacent tothe groove with the-bars of the staples substantially parallel to the groove. While the invention is: described herein with reference to the, "manufacture of. Mo- Kay shoes, it shouldv be understood that this is merely for the purpose of illustration and thatjin various of its aspects it is not lim'ited'thereto. 1
In the drawings,
Fig. 1 is a perspective view of a McKay shoe in process of manufacture; and
Fig. 2 1s a sectional new on a larger scale .showing the relation of the staple to the groove and channel of the outsole of the shoe. V
. In manufacturing shoes in accordance with my invention, the shoe upper 10 is lasted to an insole 1:2 upon a last l l having :an iron bottom 16 in accordance with a usual practice. An outsole 18 having a channel 20 extending from the heel-breast line,
through the shank, about the forepart of the shoe, and back to the heel-breast line 'nponthe other side of the shoe, is then preliminarily attached to the lasted shoe upper andin'sole. The outsole is provided with a stitch receiving groove 22 located in the channel parallel tothe; edge of the shoe,
there being a shoulder 24 formed by the "bottom of the channel 20 and a wall of the groove 22. A flap 26 is formed during the channeling operation and later is laid to cover the sole attaching means. The 0perative, after properly positioning the out sole relatively to the lasted shoe upper and insole, attaches it preliminarily thereto by a plurality of staples 28 located, preferably and as illustrated, at the tip line, the ball line, and in the .shank. These staples are inserted throughv the shoulder 24 of the groove closely adjacent to the groove with stitch' tion.
their bars extending substantially parallel groove and by througli-and-tlirough stitchto the groove, both legs of each statple being clenched a ainst the iron bottom 0 the last.

heel-seat portion of the outsole to the insole and per. a
If t shoe has a sufliciently pointed toe so that it is not desired to continue the around he toe then a group of staples 32 is inserted around the toe permanently to hold the toe portion of the outsole to the lasted upper and insole. The positioning of the outsole and the driving of these various staples constitute the sole laying opera- After the sole has been laid, the last is pulled fromthe shoe and the outsole is permanently attached to the upper and insole by which the sole is to be attached by through-and-through stitching 34, ex-
tending either from the heel breast line for wardly around the toe and back to the heel breast line or, if the toe of the outsole is attached only by staples as indicated in Fig. 1, from the heel breast line to the tip. line on both sides of the shoe. If the needle 36 of thestitcher should descend in close proximity to the bar of one of the staples, its barb cannotcatch upon the bar of the sta file as the needle is withdrawn, as it might o and often doeswhen the bars of thestaplesare positioned transversel of the ve. Accordingly the possibi ity of the reaking of the needle or damaging the thread is minimized, and a strong seam results. 7
Having described my invention, what I claim as new and desire to secure byLetters Patent of the United States is:
1., That improvement in methods of sole laying which comprises preliminarily attaching a channeled and rooved'outsole to the lasted u per and insofia of a shoe by insorting stap es in the shoulder of the groove of the outsole and adjacent to the groove with thebars of the staples substantially arallel fto the groove, and clenching both ll? of each staple.
i That improvement in methods of manu- ,facturing shoes comprising preliminarily attaching an outsole, channeled and grooved for stitching, to a lasted shoe upper and insole by staples located in the shoulder of the groove and adjacent to the groove with the bars of the staples substantially parallel to "the groove and permanently attaching the sole to the lasted shoe upper and insole by thnough-and-through stitching located in the groove of the outsole.
" 8. A shoe having a grooved and channeled outsole attached to the insole and upper of the shoe staples inserted in the shoulder of the groove adjacent to the groove with their bars substantially parallel to the .GUY R. COYNE.
