LAST FOR FOOTWEAR.

To all whom it may concern:

Be it known that I, EBERHARD MijLLER, subject of the German Emperor, residing at Bethmaunstrasse 48, Frankfort-on-the-Main, Germany, have invented new and useful Improvements in Lasts for Footwear, ofv

which the following is a specification.

This invention relates to the construct on of'an improved shoe-last for footwear with the lacing line lying to the inside.

In order to prevent the upper leather of the footwear from overhanging the edge of the sole on the outside, so-called bent lasts have already been used in the making of shoes by means of which in the shoes constructed upon them, the feet of the wearers a have been pressed inward bv the curved parts, and caused ,to press firmly against the inner edge of the shoe. In contradistinction to this construction of the last, by which the shoe built thereonv must eventually injure the foot, the present invention is devised to attain the same effect by the arrangement that the shoe last after the foot has been outlined is constructed on a ridge line-drawn along the four-fifth part point at the widest breadth of the foot and with a middle foot line drawn from the center point of the heel to the middle point of the lineofthe greatest width of the foot,

whereupon an ordinary symmetrically constructed shoe can be built up in the well known manner over the last with the lacing line lying to the inside.

Instead of giving the shoe an artificial tension on the foot arch which must injure the foot in time, by the. use of the above described special construction of last, the shoe in the unweighted condition fits firmly upon the top of the foot, and hangs'froni it and the inner part ofthe upper leather from the ridge inward is drawn even with the unweighted foot firmly over the arch to an almost smooth-surface, so that the arch remains supported even without artificial tension, as soon as the foot is weighted, because the smooth surface in an arched construction can only bend by shortening whereas a curved surface can only be held in position by a resistance.

It is already known to construct shoe lasts essentially in a line drawn from the middle point of the heel, to a two-third part point Specification of Letters Patent.

of the line through the widest part of the foot, but in these cases there has not been obtained the inwardly turned shape of shoe which assures the arch of the foot from sagging and gives to the toes a sufliciently free space combined with such a utilization of the room that the shoe shapepossesses no coarse and expressionless lines.

The attached drawing illustrates the new construction as applied to a last.

Figure 1 shows a view of the sole, and Fig. 2 shows a view of the last from above.

In the construction of the last, the operator proceeds as follows :The shape of the foot is first marked and at the level of the greatest width the transverse line 1 is drawn. Through the one-fifth part point 2- on this line the ridge line 3 is then drawn and through the half-way point 4 of this line, the middle foot line 5 is drawn and through the two-third part point 6 of this line, the lacing line 7 is drawn, all of them proceeding from the center of the heel. The other measurements are provided in the well known manner, care being taken to observe that all surfaces especially on the inner foot surface are to be set up as vertically as possible upon the ground plan. After the shape of the last has been established, the

normal symmetrically constructed shaft. is

so built up on this last that the lacing line 7 and the upper shaft come together in the direction of the line? on the last. The further shaping of the last takes place in the well known manner.
