METHOD OF MAKING WELT SHOES.

Applicationv filed August 31, 1,925. Serial- No.753,5112v.

This 'invention involves certain improvements upon the shoe disclosed in my prior Patent, No. 1,587,787, granted June 8, 1926, and the method of producing such shoe disclosed in my prior Patent, No. 1,528,260,

granted March 3, 1925, to which reference is made as illustrating the particular type of shoe involved herein.

Shoes built in accordance. with said patents are characterized by a smooth, flat, level bearing or tread foundation, but Where there is any variation in the Weight of either the insole or the Welting, or any irregularity in the stitching, such tread foundation may appear to be not Wholly flat and level when the yshoe is new and before it has been Worn. This is due to the fact that the upper land lining have not yet dropped down to smoothness With the insole, but as soon as the shoe is laced on the foot this condition is automatically remedied. The objection is, therefore, more fancied than'real, but in order to overcome it I have devised my present invention.

According to it, the shoe When finished is wholly smooth, flat and level on the inside and there is no trace or suggestion of even the slightest temporary seam or ridge aty the juncture 0f the upper and lining With theinsole. I accomplish this result by grooving or otherwise counter-sinking the bottom of the last in the region which will underlie the juncture of the upper and lining with the insole when the shoe Vis lasted. groove permits the upper and lining to sink down to smoothness with the insole under the leveling pressure When the shoe is leveled, so that all possibility of even the slightest trace of a temporary ridge or seam is obviated, with the result that even before the shoe is drawn on the foot and Worn, the tread foundation is absolutely smooth, level and flat.

The method of practicing my invention, together with a characteristic last for carrying out the principles involved, is vdescribed and illustrated in the accompanying speciication and drawings, throughout which like reference characters are used to indicate corresponding parts. In the drawings:

Fig. l is a bottom view of a last in accordance with my invention, and

Fig. 2 is a cross section through upper. Y

In accordance With the method disclosed the lasted This in my prior patent, the insole l is channeled to produce a vfull feather, portions of vvhichl are subsequently removed in the region of the shank and ball portion of the insole, so that a portion of the edge face vof the insole extending the full thickness of the insolev is definitely set in from the outer edge ofthe bottom face of the last` L. The linsole `is also provided With the usual inner channel 2 extending a substantial distance belovv the outer face of the insole.

According to my present invention, the

bottom face of the last is grooved or otherwise counter-sunk as indicated at 3. This counter-sink corresponds to the insetting of the edge face of the insole so that when the Welt 4 and upper 5 are stitched at 6 V(Fig. 2)

Within the inseam channel 2 of the insole and the shoe leveled, the upper (and lining, if the shoe is l.ined,) may sink down inthe groove or counter-sink 3 to smoothness with the insole, land present a tight smooth oint.

This .results in the elimination of any temporary ridge or seam at the juncture of the upper and lining With the insole, and even though such ridge automatically j smooths out as soon as the shoe is drawn on the foot, my invention nevertheless is of advantage in that it avoids possible criticism of theshoe as not being initially smooth and flat on the inside.

Various modifications in the form and construction of my device may obviously be resorted to Without departing from the spirit of my invention if Within the limits of the appended claims.

What I therefore claim and desire to secure by Letters Patent is:

l. In the method of making a Welt shoe having a substantially flat tread foundation, that improvement which consists inproviding a last having a countersunk portionl in its bottom face and inset from its marginal edge, in temporarily fastening to said last a channeled insole having a projecting feather, portions of which in the region of the ball and shank have been removed to bring the edge face of the insole at these points definitely Within the marginal edge'v of the last,

last that portionv of the upper overlying the same whereby to form a tight smooth joint With thel insole on the inside of the shoe.

2. In the method of making a Welt shoe having a substantially tlatvtre'ad foundation, that improvement which consists in providing a last having a groove in its bottom face and inset `from its marginal edge and extendingrabout'its fore part, in' temporarily fastening to said last a channeled insole having a 4projecting' feather, portions of `Whiohin the region of the ball andvshank have' been removed to bring the edge' face of the insole at these points definitely Within the marginalA edge of the last, intemporarllylasting an upper over the lnset'j tion of the upper overlying the same'whereby to Jform a tight smooth joint With the in'- sole'on the inside of the shoe.
