SPECIFICATION forming part of Letters Patent No. 594,957, dated December '7, 1897.

' Application filed November 21, 1896. Serial No. 613,018., flIo model.) I

T0 at whom it may concern.-

Be it known that I, FREDERICK W. LYNN, a citizen. of the United States,re'siding at Natick, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Machines for Removing the Gore-Pieces from the Linings of 7 Shoes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,forming a part of this specification, in explaining its nature. 7

Congress shoes having elastic gore-pieces are generally during their manufacture provided with an inelastic lining which is stitched to the upper to cover the gores and by seams which extend parallel with the edges of the gores, and the lining thus stitched is then subjected to an operation whereby the sections thereof which cover the gores are-removed in order that the said sections may not impede or interfere with the elasticity of the gores. These pieces so removed from the lining have generally been cut from it by scissors and is a slow operation.

My invention relates toa device or machine for cutting said lining upon the line of the gore-seams and upon the presentation of the upper thereto.

In the drawings, Figure 1 is a view in perspective of a machine having the features of my invention, showing in dotted outline the manner of presenting the upper thereto. Fig.

2 is a view in vertical section thereof upon the dotted line 2 2 of Fig. 1. Fig. 3 is a view in side elevation of the interior of an upper, representing the lining as stitched thereto and covering the gore. Fig. 4 is a view of the same part of the upper, showing the section of the lining which covers the gore as removed.

A represents the upper; a, the lining; b, one of the gores, and c c the vertical seams at each edge of the gore.

The office of the machine is to remove the part of the lining between the seams 'c c and in line therewith to or very nearly to the seam 0 The machine embraces a shaft D, mounted upon a suitable stand cl, adapted to be attached to a table or bed and having a pulley d for the reception of a driving-belt. This shaft extends outward from the stand a considerable distance and carries at its outer end a cutting-disk d having a sharp cutting edge 01 this disk being removable from the end of the shaft. Upon the under side of the disk are the gages e a. They are parallel with each other, are separated by the recess e which receives the edge of the cutter, and they extend forward from the lower end of the supporting-arm 6 the said arm extending backward and downward and being attached to the stand 6?. The forward ends of the gages extend somewhat in advance of the cutting edge of the cutter, and each gage is made thin and of a depth to shield by their under surfaces 6 the upper from contact with the edge of the cutter and so form a cutterguard. The cutter is also covered by a shield f, attached to the upper surface of the arm 6 and extending downward very nearly to the ends of the gages, there being between them an opening sufficient only for the passage of the lining onto the upper surfaces of the gages. By this construction all danger of the upper coming in contact with the cutter and being mutilated by unskilful manipulation on the part of the operator is obviated and the operator is protected from being out while at work.

In operation the upper is presented to the cutter with the lining uppermost, the gages being inserted into the opening between the lining and the gore and with one of the gages in contact with one of the seams c c. The upper is then fed or moved forward, causing the gore to move under the gages and the lining to move over them and a cut to be formed upon the line of one of the scams 0 c and removed from it a distance equal to the thicknessof the gage. After the cutter has made 7 a cut in the lining upon the line of one seam the upper is removed or turned and a out upon the line of the other scam is then made and the upper is turned and a out upon the line of the seam 0 made, thereby completely severing the said section of the lining.

It will be seen that the gages serve to protect the upper and gore from injury and to act as a rest for the lining during the cutting operation and as gages for determining the line of the cut that the shield serves to cover more thicknesses of material one of the thicknesses or a portion thereof by means of a gage and guard or a guard alone introduced between the thicknesses and shielding the one or those not to be cut from the one which is cut and also acting as a rest for the one that is cut, all used in conjunction with the cutter.

It will be understood that the parts a e,

which I have termed gages, but which have not only the function of a gage, but act as guides, protectors, supporters, and separators-guides in that they guide the direction of the cut by means of the side seam, protectors in that they protect the thickness of the material which is not to be cut from injury, supporters in that they support a part of the material upon which the cutter works, and separators in that they separate one thickness of the material from the other--may have a more comprehensive term, and perhaps feet would be as comprehensive a term as any, and I would also say that while I have shown two feet for certain uses one will answer.

It will be seen that in the operation of the device the two thicknesses are separated by the foot or feet, the relation of the cut to a seam or any other line determined by the guide or gage, and that the outer surface or surfaces of the feet are shaped to permit the feeding or movement of the uncut thickness, and that this is true whether the invention is used to cut out from the uppers the goresections of linings or for cutting from one of two thicknesses which are simultaneously fed to the cutting device and without injury to the other.

For the purpose of convenience the feet are shown upon the under side of the cutter, but they may be upon the upper or any other side thereof.

Having thus fully described my invention, I claim and desire to secure by Letters-Patent of the United States- 1. In a cloth-cutting machine, the combination with a supporting base or standard, of a cutter mounted therein, and a thin or narrow separating-foot and cutter-guard having an unobstructed space beneath it and being thus adapted to be inserted between two thicknesses of material so as to determine the position of the cut in the thickness to be severed and prevent injury to the other thick- '-ness from the cutter.

2. In a cloth-cutting machine, the combination with a supporting base or standard, of a cutter mounted therein, and a thin or narrow separating-foot and cutter-guard, said foot or guard having an extension beyond the cutting edge of said cutter, said foot or guard having an unobstructed space beneath it and being thus adapted to be inserted between two thicknesses of material so as to determine the position of the out in the thickness to be severed and prevent injury to the other thickness from the cutter.

. 3. In a machine for cutting gore-pieces from shoe-linings, the combination with a suitable base, of a rotary cutter mounted therein, and a foot consisting of the two members e, e, disposed on either side of said rotary cutter so as that they lap the same and guard the edge thereof, said members 6, e having ends which project beyond the edge of said rotary cutter and being formed thin or narrow so as to permit the lining to be severed close to the gore-seam and the cutter to be guided by said scam, the lower surfaces of the said foot members being unobstructed; whereby a thickness of material fed upon one surface of the said foot members is adapted to be out while the thickness upon the other surface may be fed without being cut and without obstruction.

4. In a machine for cutting gore-pieces from the lining of shoes, the combination with a supporting base or standard, of a cutter mounted therein, one or more thin or narrow feet extending both above and below the severing edge of the cutter and in close proximity to the same, so as to permit trimming action by said cutter close to a gore-seam, said feet projecting beyond the cutting edge of the cutter and a shield, as f, in front of said cutter and closely adjacent to the projecting ends of said feet so as to, permit not only the feeding of one of two thicknesses of material to the cutter and guard the other thickness from mutilation but also to protect the operatorfrom injury.
