UNITED STATES PATENT OFFICE,

BOOT AND SHOE.

Application filed May 26, 1927, Serial No. 19&,'739,` and in Great Britain May 7, 1926.

Thisinvention relates to boots and shoes of machine sewn and similar type, and has for its object an improvement in the oonstruction thereof for the purpose of rendere ing such footwear waterproof by preventing or minimizing the access of damp or moisture to the foot of the wearer through the bottom of the boot or shoe and at t-he edge or feather ywhere the upper is drawn and l lasted over the insole.

According to this invention, there is disposed between the insole and the outer soleq or between the insole and the middle sole, if

a middle sole be employed-a sheet of rubber or other suitable waterproof material `(hereinmter, for convenience of reference, designated filler) having a flanged or beaded edge which fits closely against the edge or feather of the upper and so that it is visible outside the boot or shoe.

ln the application of our invention to a boot or shoe of the machine sewn, nailed, pegged or screwed type, a flanged or beaded filler is placed over the4 insole and the edges of the lasted upper after the lasting opera* tion has been completed; saidller preferably varying in thickness so that the space between the insole and the edge of the lasted upper is filled up level for the reception of the outer sole, or middle sole, as the case may be. i i

Said flanged or beaded filler-edge may eX tend only round Athe fore part of the filler, or, where the filler is carried through to the heel, the flanged or beaded 'edge may `extend completely round the filler.

Whensaid flanged or beaded filler is constructed of rubber, this will preferably be of such nature as to ensure that the holes made by the. sewing needle or awl will close tightly.

ln some cases, perforations--remote from the flanged or beaded edge, and which may be filled with cork, or the lilre-inay be provided in the filler for the purpose of ventilation: or a filler may befpartially split to provide some ventilation, and also enable the filler to be adaptable to boots and shoes which may*within limits*vary in shape.

7e will further describe our invention with the aid of the accompanying sheet of explanatory drawings which illustrate, by way of examples only, two modes of carry' ing the invention into effect.

In said drawings Fig. l is an elevation, and Fig. 2 a partsectional elevation of a machine sewn shoe embodying our improvement; Fig. 3 is aperspective view of the shoe having a. part broken away, and Fig. 4t is a plan of the flanged or beaded filler detached. Fig. 5 is a plan of a flanged orbeaded iiller of modi- .lied construction, and Fig. 6 is a reduced perspective view of a fragment of a filler according to a further modification. Fig. 7 a half-transverse section of a machine sewn shoe of modilied construction, and drawn to an enlarged scale as compared with the preceding views.

In the several views like characters of reference denote lille or equivalent parts wherever they occur.

Referring first, more particularly, to Figs. l to 5, inclusive, t indicates the upper of the shoe, the insole, and c the outer sole. Disposed between the insole o and outer solec is a filler dof rubber provided with an integrally moulded bead or flange d1.

Said filler Z is thickened at Z2 in order to lill up the customary spaceformed by the lasting of the upper.

In the manufacture of the shoe, said ruhber filler is applied after the upper (i has been pulled and lasted over the insole, and is prevented from displacement by means of tacks or ay suitable adhesive: the flanged or beaded edge ZL-which is visible outside the shoe-of the filler lies closely against the edge or feather of the lasted upper and forms a watertight joint at this part. The outer sole 0 is now placed in position and sewn in the usual manner.

The flanged or beaded filler illustrated in Figs. l to 4 extends along the waist of the shoe and terminates adjacent to the seat.

The modified filler illustrated in Fig. 5 is constructed to extend throughout the length of the shoe, so that its flanged or beaded edge Z1 entirely surrounds same.

The filler illustrated in Fig. 6 is partially split by an inclined cut, in the .manner i shown at y', to provide some ventilation, as-

also to enable the filler to be adaptable to boots and shoes which may-within limitsvary in shape. v

In the modification illustrated in Fig. 7, the slice construction is similar to that already described except that a middle sole c is provided betweenthe filler and the outer sole o.

f indicates the Sewing which secures the outer sole c-or outer and middle soles'fc,` e, respectively, as the case may be-iiller (l, upper (L, and insole Z) together; and 'g de notes the tacks which secure upper ci and insoles?) together. y

As will beseen, a section taken transversely through `thewiiller within the tread portion, presents the characteristic ot' a channel on its upper tace, Vsaid channel extending troni the bead cl `to the portion Zi'ollowing the contour 'of thehead and being oiE substantially uniform width, with the depth ot thefchannel such'that the thickness of the cliannelled portion andl that of the margin of the upper which extends therein Substantially equals the thickness ot the sheet between opposite side portions of the channel direction oi length, this latter portion ot' the sheet being the portion (l2, whether the arrangement be ot the `form oi Fig. ,tfin which the channel extends approximately trom 4the shank portion of the sheet on one side ot' the shoe to the shankportion ot the sheet on the other side of the shoe-or the i'orm ot Fig. 5 in which,` the channel is eitended into the heel portion of the sheet. i a

This arrangement is oi" importance hecause of the fact that the margin of the upper does not increase the material thickness beneath the insole, so thatthelatter canextend in its normal manner throughout the width of theshoe and not provide any tendency of thet'ormation of a raised portion around the edge "of the vinsole during use, and at the saine time permitting the `insole to `he of the usual type. Hence, the slice equipped with the filler sheet has the co1nfort of the welt typeot shoe-#in which the margin of the upper does not materially underlie the insole-and at the same timle'protype, having an inner sole and another sole.

below it with the margin of the upper extending into interposed relation therebetween, a iiller sheet oi' waterproof material disposed between said soles and underlying the interposed margin oi the upper7 said iiller sheet having a channel to receive the inturned margin oit-the upper and also having its margin oit head 'i'orin with the than` nel extending to said head, said marginal bead closely fitting against the edge oi: the upper and being visible outside of the boot or shoe7 and, stitching extending through said solesfthe margin of the upper and the channelled portion of the liller sheet.

i2. A boot or shoe as in claim l characterized in that the channel is of substantially uniform width and has a depth such that the thickness of the channelled portion ot the sheet and that ot the margin of the upper substantially' equals the thickness oi the sheet between opposite side portions of the channel length. i

3. A boot or shoe asin claim l character- `ized in that the channel is oi'v suhstantiall),r uniirorin width and has a depth such that the thickness ot the channelled portieri of the sheet and that oi` the margin o'fthe upper substantially equals the thickness of the sheet between opposite side portions of the channel length, the channel extending ap-` proximately from the shank portion ot' the sheet at one side of thcshoe to the shank portion ot the sheet at the other side ot the shoe. V

In testimony whereof we allix our signa tures. a
