JAMES N. MOULTON, OF HAVERHILL, MASSACHUSETTS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE MOULTON TURNED SHOE MACHINE COMPANY.

S O L E SPECIFICATION forming part of Letters Patent No. 416,118, dated November 26, 1889.

Application filed February 18, 1889. Serial No. 300,217. (No model.)

To all whom it may concern.-

Be it known that I, JAMES N. MOULTON, of Haverhill, county of Essex, State of Massachusetts, have invented an Improvement in Soles, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object an improved construction of sole, wh ereby the upper may be readily attached to it, using a straight needle in a needle-bar of a sole-sewing machine. To enable the lip or part of the sole which the needle enters in securing it to the upper to be entered by a straight needle in the needle-bar of a sewing-machine, it is necessary to throw the said lip up well away from the level of the sole, so as to produce a sole having a lip sufficientl y elevated for the passage through it of a straight needle. I have cut the sole from its edge inwardly for a short distance and substantially parallel with the sole; but back in at one side thereof I have cut a channel which is inclined outwardly, leaving between the base of the cuts forming the two channels a portion of the sole which is offset or elevated substantially at right angles to the thickness of the sole. The sole having been cut, as described, has the edges of the lip formed bycutting into it, as described, turned up, and the substance of the sole at the opposite side thereof, in which the cuts are made to form the lip, is subjected to pressure sufficiently to strike or set off that portion of the sole with which the substance between the base of the cuts is connected, thus leaving the lip standing'out prominently from one side of the sole and above the level of the central. part of the sole.

My invention consists, essentially, in a sole having projecting channel lips or flaps, one cut from the inner portion of the sole outwardly, and the other from the edge inwardly, and the substance of the sole between the base of said flaps offset or elevated substantially at right angles to the thickness of the sole, substantially as will be described.

Figure 1 of the drawings represents in plan View a sole embodying my invention; Fig. 2,

a cross-section thereof in the line 00. Fig. 3 represents a cross-section of the leather from which the sole is made after the same has been channeled, and Fig. '4 is a like section showing the edges of the lip turned up pre vious to offsetting or elevating the substance between the base of the cuts. 4

In the formation of my improved sole I take a piece of sole-leather, and, as best shown in Fig. 8, I form in the edge of the same a cut, as at 2, the said out being more or less beveled, according to the thickness that it is desired the finished edge of the sole shall present. I then, or at the same time, but a second channel 3, the out being directed from toward the central part of the sole outwardly. These two cuts leave two edges, and between the base of one cut and the base of the other there is left a portion of the leather marked 1). Next, the two edges so formed by making the cuts described are turned up together, as in Fig. i, and subjected to pressure, and at the same time the face of the sole opposite that which receives the cuts 2 and 3 is subjected to a pressure which causes the between substance of the sole, with its connected flaps, to be raised or offset, as in Fig. 2, to occupy a position as to the general level of the sole different from what it occupied when the channels were cut as described. This offsetting or elevating of the substance between the base of the cuts and its flaps above the level of the central part of the sole results in leaving a concavity at the opposite side of the sole, (see Fig. 2,) which is parallel with the line occupied by the said substance, and also results in setting up the said substance and its flaps enough above the face of the sole, close to which the needle is to work, that the needle, even though a straight one carried by a reciprocating straight bar, may readily pass into the said substance at the inner side of the lip and out through the said substance into the upper; and this is true whether the sole be channeled for a turned shoe or for the inner sole of a welted shoe.

I do not broadly claim a channel-flap having two lips extended in opposite directions from a substance between the base of the cuts and turned up 5 but prior to my invention I am not aware that the said substance itself has been elevated or offset in the direction of the thickness of the sole.

I claim- As an improved article of manufacture, a sole having projecting channel lips or flaps, one cut from the inner portion of the sole outwardly and the other-'from the edge inwardly, and the substance of the sole between 10 the base of said flaps offset or elevated sub-' stantially at right angles to the thickness of the'sole, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witn esses.

JAMES N. MOULTON.
