BOOT OR SHOE SOLE.

SPECIFICATION forming part of Letters Patent No. 305,834, dated September 30, 1884. Application ined June an, rees. (nu man.)

To a/ZZ wife/m zi may concern.-

Be it known that I, LEE E. MOORE, of Boston, county of Suffolk, State of Massachusetts, have invented a new and useful Improvement in Soles for Boots or Shoes, of which the following is a full, clear, concise, and exact description, taken in connection with the drawings, accompanying and forming a part hereof, of which- Figure I is a perspective View of a soleblanlr channeled. Fig. 2 is a cross-section on line m, Fig. 1. Fig. 3 is a lengthwise section of a sole tted for the last, showing the entire edge of the blank turned down, substantially at right angles to the body thereof,

V to form a flange.

My invention consists of a sole fitted inthe peculiar manner shown and hereinafter de scribed and ready for use in the construction of a boot or shoe.

The manner of fitting the sole -will be read ily understood, reference being had to the accompanying drawings. A fiat blank, A, is rounded out to the proper shape ot' a sole, but somewhat larger than is required to tit the last. Itis then out or channelled inwardly parallel to and within the edge, as shown at it, Figs. I and 2, thus forming the feather a, which becomes the edge of the completed sole. The outer edge of the channel h is shown rounded, Fig. 2, producing a corresponding round on the feather, which is generally desirable; but it will be obvious that in some cases a square-edged feather may be preferred, which may easily be obtained by cutting a square-edged channel. The margin c, or that portion of the blank outside of the edge of the feather, ,and also that portion of the stock beneath the cut or channel,are then bent or turned away from the feather, and by the operation of a machine adapted to do this work the iiange b thus formed is made to as-y sume and retaina position substantially at right angles to the solesurfaces. It will thus 5 be seen that the flange b is wider than the feather a, being approximately equal in width to the width oi' the feather plus the width of the margin c.

My sole is designed for use in boots or shoes the uppers and soies of which are united by sewing on a wax-thread machine provided with the attachment shown and described in Letters Patent to James H. Cutter, dated the 10th day of April, 1883, No. 275,365. In preparing the work for the machine the npper is brought over the feather c and against the flange i), and the stitches pass through the iiange and upper (or flange-upper and welt, if a welt be used) at the base of the iiange where it joins the sole.

` In the operation of sewing, the flange, above which lies the edge of the upper, projects between the work-rest and guide of the machine and the 'presser-foot, the flange, constructed as hereinbefore described, being of sufficient width to enable the presser-foot to hold the work securely on the Work-rest and guide, thus steadying the Work and assisting the operator in manipulating the shoe, thereby rendering it possible to place the line ot' 7o stitches more accurately and with Y greater speed than heretofore on wax-thread machines using a straight needle.

The hereinbefore-described sole may be applied to a boot or shoe in the manner shown by my Patent No. 275,248,dated April 3, 1883. It will, however, be obvious that as my present sole has a flange oi' greater width relative to the feather (the width of which latter it is desirable to limit) than the sole shown in said patent, the presser-foot is enabled to hold the work on the work-rest and guide more securely than was possible with my former sole. The sewing may accordingly be done better and more rapidly.

Havingthus described myinvention, I claim and desire to secure by Letters Patent- A boot or shoe sole made from a rounded out blank cut inwardly from the edge on its upper surface to form a feather, a, leaving a margin the normal thickness of the sole,or approximately so, said edge and the cut or channelled portion forming a flange, b, wider than the said feather, said iiange being turned away from the said feather and made to assume and retain a position substantially at right angles to the sole-surfaces, as set forth.
