conrona'rron OF INDIANA roam-marine 3001' Original application filed December 12, 1927, Serial 1T0: 239,385. Divided and. this application fled November 30,- 1928.

, My invention relates to footwear of the high top type commonly known as boots, and

has reference more particularly to the construction thereof with a permanently closed 'form fitting ankle and instep portion which may be enlarged to facilitate putting on and removing the boot., I

High top boots and especially those of rubber are usually made large and loose fitting at the ankle and instep to permit inserting' and removing the foot, as it is quite diflicult to make a boot of this character witha satisfactory expansible'ankle and instep' portion which will stand the required usage without developing leaks. It is desirable however to make the boot in a close fitting form, not only for the sake of improved appearance, but also to hold the boot securely in place and avoid the discomfort of the foot: working up and down in the boot. Withmy invention this. is accomplished, and an expansible ankle and instep construction provided, which will remain waterproof throughout the life of the boot. 1

The principal objects of my invention are to provide an improved form fitting boot; :to insure a substantial and effective waterproof construction at the ankle and instep which permits enlargement at this point for applying and removing the boot; to con-- struct'the ankle and instep portion of the boot with an expansible pouch-like closure having flaps with a detachable connection for fitting the boot-around the ankle and instep to utilize a special form of closing member at the ankle and instep, which folds into a compact and comfortable form and permits enlargement without stretching or other strains which might impair its water resistingcharacter; and in general, to provide a neat, at-

tractive and substantial form fitting boot of simple construction.

This application is a, division of my pending application, Serial No. 239,885, filed December 12-, 1927, which relates to a method of making form fitting boots.

Fig. is a similar view showing a subsequent step in the assembling of the expansible instep closing parts. I

Referring to the drawing, which shows my invention applied to a boot of knee length, although it is of course intended for use with boots of other lengths, the reference numeral 1 indicates the boot as a whole which is divided along the line 2 over the ankle and instep to form a pair of separable flaps 3 and 4, which are detachably connected in the closed form fitting position by buckles 5 of a well knownform or these flaps may be connected with any other'suitab e type of fastening devices. The flaps 3 and 4 are flared at their lower ends as indicated at 6 and 7respectively, forming a.blucher type of opening, and the vamp of the boot is provided with an extension 8 runnin up to and 1 0t at the upper endof the'opening 2, said extension secured to the front wall of the being provided at each side with inturned flaps 9 and 10 respectively, which are secured along their outer edges to theborresponding the separable boot flaps 3 and 4, and at the same time permits separation of the boot flaps 3 and 4 and enlargement of the boot at the ankle and the instep for inserting and removing the foot.

As a further means of affording a close fitting of a bootof the knee length type, the latter may be provided at the upper end with a slit 11 and a strap and buckle fastener 12, or other suitable fastener for detachably connecting the portions of the upper at opposite sides of the slit 11, and the edges of the upper at opposite sides of the slit 11 are connected by a gore 13, which permits any desired expansion of the upper and folds down fiat against the leg when the portions at opposite sides of the slit 11 are connected together.

\Vhile this construction may e used for any type of boot, it is particularly useful in connection with rubber boots, as it affords an expansible ankle and instep portion which will stand up under conditions of use to which rubber boots are subjected, without developing leaks which would impair the usefulness of the boot.

In making up a rubber boot with this ankle and instep construction, I prefer to proceed in the following manner: A pair of similar half sections of lining or quarters 14 of the form shown in Fig. 4 (which however has the upper portion broken away) are prepared and have the edges 15 of the toe portion secured together by a tape 16 or in other convenient manner. A vamp extension 8 of rubber composition, which" forms the back wall of the pouch or closing member, is prepared in substantially the form shown in Fig. 5, and has a lining 17 of fabric adhesively secured to the back thereof, said lining being of somewhat smaller size than the vamp extension 8 to leave a marginal edge 18 of the vamp extension 8 exposed on the under side. A pair of side flaps 9=and 10 of rubber composition with fabric facing. 19 (see Fig. 6) are then laid over the vamp section8 or back member of the pouch or closing member. and have their marginal edges/turned in under and secured. to a marginal edge of the vamp ex- I tension 8 asindicatedin Fig. 6, said flaps 9 and 10 being arranged so that they meet sub stantiallyalong the-longitudinal axis of the vamp extension-8, and these'flaps 9 and 10 have theirlower ends reversely flared as inclicatedat 20-,and 21 respectively to correspond to edge and secured together by to the blueher form or flaring arrangement 6 and 7 of the boot flaps 3 and 4.

' After the pouch-like closing member has beenprepared in this manner, the rounded lower end thereof between the points H in Fig. 5 is laid over and secured to the upper end of the joined together toe portions of the lining 14-14 as shown in Fig. 9, sothat the points zit-w of the closing member register with the points y- 1 of the assembled lining, whereupon the edge portions of the two parts of the lining from the point y to approximately the point z of Fig. 4 are laid over and secured to the edges of the respective flaps 9 and 10. The forward edges of the two lining sections 14-14 at the upper end of the closing member and therebeyond to the top of the boot are then arranged edge a tape 22, and the pouch-like closing member is also temporarily closed by bringing the edges of the lining section 14-14 and with them the edges .of the pouch flaps 9 and 10 together, as shown in Fig. 2 and applying a tape 23 across the meeting edges.

For reinforcing and insuring a thorough sealing of the connections between the various parts at the lower end of the closing member. a cap 24 of rubber composition of substantially the plied as shown in Fig. 2, so that, it extends well down below and above the juncture line of the vamp portionof the lining sections 14-14 and the vamp extension 8, while the side lobes 25 of the cap 24 are folded over the lower ends of the side flaps 9 and 10 and the overlying portions of the lining around the points m-y, so that the corner connections of the flaps with the vamp portion of the shoe are well protected and thoroughly sealed against possibility of leakage.

After the lining and pocket closing member has been prepared, as above described, the assembled structure is stretched around a last 26, as indicated in'Fig. 2, and the edges of the lining sections 1414 are brought to 'gether at the back and secured together; in any convenient manner, as by overlapping and cementing or taping. After the lining has been applied on the last, the sole is built up in the usual manner, and the facing of rubber composition applied over the lining to complete the upper, said facing being preferably provided with a pointed portion which fits up between the curved lower ends 6 and 7 of the side flaps 3 and 4, as indicated form shown in Fig. 8 is apby dotted lines at 28 in .Fig. 1, and the facing on the side flaps 3 and 4 being continuous across the line of separation 2, so that the side flaps 3 and 4 are joined together by the facing, the line of division being preferably marked by a score line which terminates near the upper end of the pocket or closing member, while the side portions of the upper thereabove are overlapped or provided with reinforcing 29,'so that the side flaps 3 and 4 a reinforcing 29 extending up to the top of theboot.

After the boot has been assembled in this manner itis vulcanized, and after vulcanizing the facing 27 and the tape 23 are slit along the line 2 upto the lower end of the may be separated to expand the ankle and insteptportion of the boot for applying and removing. The fasteners 5 may be attached in any convenient manner, preferably by means of tabs which are arranged in place before the boot is vulcanized, or any other desired type of fastener may be-employed, the essential requirement being the provision of the boot with a serviceable and thoroughly waterproof expansible portion at the ankle and instep which is sufiicientlystrong and durable to avoid the necessity of making rubber boots in a loose fitting form.
