Lasting Boots and Shoes.

AM Film-Limo sRAPH/c ca Al. (ossaR/vf's macsss) UNITED VSTATES PATENT (JEEIcEo RICHARDA C. LAMBART, OF QUINCY, ASSIGNOR OF ONE-THIRD HIS RIGHT TO NATHAN C. LOMBARD, OF BOSTON, MASSACHUSETTS; SAID LAMBART SULOMBARD ASSIGNORS TO SAID LOMBARD, TRUSTEE OF THE LAMBART BOOT AND SHOE MACHINE ASSOCIATION, OF SAME PLACE.
IMPROVEMENT IN LASTING BOOTS AND SHOES.
Specification forming part of Letters Patent No. 35,133, dated January 21, 1873.
To all whom it may concern:
Beit known that I, RICHARD C. LAMBART, of Quincy, in the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in the Manufacture of Boots and Shoes, of which the following is a specification My invention relates to the manner of securing the upper to the inner sole in the process of lasting the boot or shoe, and is designed to do away with the use of pegs or nails for securing the upper to the inner sole. A large proportion of the sale boots and shoes now manufactured, in New England at least, are sewed on the McKay sewing-machine, the soles being secured to the upper 7 and the inner sole by sewing through and through all three thicknesses, the loop of the stitch being formed inside the boot, and, of course, the last must be removed before the boot is sewed, and the inner face of the inner sole must be smooth and free from projecting pegs or nails, and resort has been had to an iron-faced lastfor the purpose of clinchin g the nails used to secure the upper at the same time that they are driven. It often happens, however, that the nails are not clinched, or very imperfectly so, and they are a continual source of trouble and annoyance to the wearer. To obviate this difficulty and secure the upper to the inner sole in a substantial and, at the same time, a cheap and expeditious manner, is the object of my invention; and it consists in securing the upper to the inner sole by forcing narrow strips of said upper into slits formed in the inner sole for the purpose, said narrow strips of the upper being formed by cutting two slits in the edge of that part of the upper which is turned over onto the inner solein the process of lasting, at suitable distances apart, and said strip is then forced into the slit in the inner sole without severing its connection with the main body of the upper. These narrow strips of the upper become so many leather pegs or thongs, one end of each of which is connected to the main body of the upper, while the other end is held firmly in the slit formed in the inner sole. It also consists in a peculiar arrangement of the slits in the inner sole, and a peculiar manner of cutting the strips or thongs in the edge of upper, whereby the operation of forcing said thongs into the inner sole is facilitated, and by which they are retained more readily in place, which will be hereafter explained.
Figure l of the drawing is a plan of a lasted shoe before the outer sole is attached, showing my invention. Fig. 2 is a transverse section on line .r on Fig. 1. Fig. 3 is a similar section with the outer sole attached; and Fig. v
4 is a longitudinal section of a portion of the shoe on line z e on Fig. 1, and showing the manner of cutting the strips in the upper and the slits in the inner sole.
A is the inner sole, secured to the last B in the usual manner, and C is the upperf cut and made up in the usual manner. That portion of the upper which is turned over onto the inner sole has aseries of slits cut therein, as seen at a b, Fig. 4, so as to form narrow thongs c, and directly beneath said thongs are formed the slits d in the inner sole A, into which the thongs c are forced, as seen at D, Fig. 4. By reference to Fig. 4 it will be seen that the slits in the edge of the upper, which form the thongs c, are made preferably inclined in reverse directions, so that the under l side of the thong is V-shaped, and the slit d in the inner sole coincides with the slit a in the upper, so that the thong c may be readily forced into the slit d, and, being bent to one side by being forced therein, it is held more rmly in place than it would be if the slit d were at right angles to the surface of the inner sole.
By the use of this process for lasting boots and shoes a common wooden last may be used, and the boot or shoe may be fitted thereto and secured to the inner sole without the use of v nails or pegs, excepting two tacks to hold the inner sole in place till the upper is secured thereto, when said tacks may be withdrawn and the outer sole may be fitted and secured in place, when the last may be withdrawn, and
the shoe is ready for sewing, with :t perfectly smooth inner surface to the inner` sole, Without nails or pegs to gell the feet.
'What I claim as new, and desire to secure by Letters Patent of the United States, is
l. The process of lasting boots or shoes and securing the uppers to the inner soles Without the use of nails, pegs, or sewing, by forcing thongs cnt from and. forming a part' of the upper into slits out in the inner soles, substantinlly as described,
2. The angular arrangement of the slits a, b, and d, as herein set forth and described, for the purpose specified.
Executed at Boston this 5th cla-y of December, 1872.
RICHARD C. LAMBART.
