SHOE-LAST.

Intented Aug. 24, 1920.

Application filed October 1, 1918. Serial No. 256,443.

the manufacture This invention relates to novel of boots and shoes and comprises a last for use in the manufacture of such articles.

One of the principal objections to shoes of the McKay and turn types is the presence of stitches or other fastenings in the inside of the shoe, where they cause discomfort to the wearer and mar the appearance of the shoe The use of an inside slip sole has not en-- tirely avoided this objection, and attempts have been made to position the fastenlngs in a channel formed in the upper face of the Great difliculty in keeping the channel flap in temper has been experienced, however, channel properly and smoothly after the attachment of the sole.

It has been proposed broadly to treat a part of the shoe lying next to the last, in particular a channel flap, assembled on the last, to insure that it w ll be in temper for subsequent operations, and in particular to keep in temper the turned up channel flap of an insole such as above described during the lasting and sole laying operations, so that it will be in properv condition to belaid and cemented smoothly after the sole attaching operation. u

A last adapted for the practice of the described process, arranged with a cavity in the bottom to hold means, such as a dampened tempering pad, for treatmga part of a shoe (in particular as herein illustrated the channel fiap) while. the shoe remains on the last, has also been proposed. The present invention provides a last .with a cavity having waterproof walls in order to prevent damage to the body of the last by moisture,

the cavitybeing adapted to hold a dampened tempering pad; Preferably, also, the narrow outside rim of the cavity is formed of some tough material, such as fiber, to enable it to withstand repeated tacking.

, the

with consequent failure to close the after the shoe is These and other features of the invention 'will be understoodfrom the followingv detised.

In the drawings,

Figure ,1 shows a perspective of the last.-

Fig. 2 is a cross section showing the step of lasting the upper.

Flg. 3 is a cross section of the completed shoe, and v f,

Fig. 4 shows the insole.

The main ,bjody 10 of the last may be 0 any desired ,ztype, as for example, solid, block, or hinge.- The bottom of the last is formed preferably of some waterproof material 12, as fiber, and contains a longitudinal depression 14. In the last shown this depression extends from near the ti to the metal heel plate 16. It is not as wide as the bottom of thelast, and leaves a strip 18 ,in

position "of the usual last bottom approximately %{inch wide around the edge of the tread face. The strip 18 may be made integral with thewaterproof last bottom 12,

' or 'may be removable, if desired, as indicated in dotted lines in Fig. 2, and will preferably be formed of material adapted to permit tacking. A dampenedpad' 20, of spongy material, as for example felt, is placed in the de ression 14.

n accordance with my invention 'the last is used as follows in the manufacture of McKay shoes I An insole 22 is channeled in its upper sur face, as. at 24. This channel runs preferably on each side of the insole from the heel 96- breast portion to a point nearthe toe tip.- The channel is preferably not run around the toe ti for the reason that such rocedure wiii weaken the insole too muc at this point, the insole stock used in shoes of 100 this type being often very inferior; and for the further reason that a channel flap at the extreme tip would interfere with the "last pulling.

The insole is applied to the last with the 106 channel flaps turned back into the depression 14 where the dam ened pad 20 keeps them in proper temper seeFig. 2). At t e same time, the waterproof bottom prevents injury to the wooden body of the last from 110 the continuous presence of the dampened pad 20. The upper 26 is then lasted and is preferably cemented to the insole 22, a few lasting tacks 28 being. driven to hold it until the cement has set, and removed before the last pulling. The fiber rim 18 has been found to permit repeated tacking much more advantageously than wood would dot Such treatment of a wooden rim of suchsmall width would soon shatter it. The last is readily removed because of the unchann'eled plate at the toe tip and the outsole may then be attached in any desired manner, the fastenings shown or stitches 30 being placed in the channel, after which the tempered flap ma be cemented down, having a flat smooth lnsole except at the toe tip where the foot is not in contact with the insole.

I do not claim broadly a last having a cavity constructed and arranged to hold means for tempering a ortion of a shoe on a last, nor do clalm t e disclosed method of manufacturing shoes com rising maintaining an internal channel ap in temper while the shoe is on a last, since these matters are not my invention.

Having described my invention, what I claim as new and desire to secure byLetters Patent of the United Statesis 2-- 1. A shoe last havinga waterproof bottom and having a cavity in said bottom con- StIlCtGd and arranged to hold a moistened 2. A shoe last having a cavity in its bottom constructed and arranged to receive a channel flap, the rim of the bottom around the cavity being composed 0t fiber.

In testimony whereof I have signed my name to this specification.
