FOOTWEAR AND METHOD OF MAKING Peter H. Margulis, New York, N. Y. v Application February 25, 1949, Serial No. 78,247

" 2 clai s. (ores-4.3)

This invention relates to snow or, waterproof I footwear and more particularly; to footwear formed of rubber or rubberized material or material combining rubber and fabric. I

This invention has for its sallentobject to provide a simple, practical and economical method of making and constructing footwear of; the character specified, such as boots, galoshes, arctics, or oxfords, that will be form fitting and attractive in appearance.

Another object of the invention is to provide footwear of the character specified so constructed as to use a minimum amount of material and to cut thetime and labor required for its manufacture. Another object of the invention is to provide footwear of the character specified having a wide entrance down to its throat and having a closing flap with a single fastener. I

Another object of the invention is to provide footwear of the character specified that will be v comfortable to the wearer, will fit snugly over insteps and'ankles of varied measurements, and

can be easily put'on and taken off without ripping or tearing the footwear. v 7 Further objects. of the invention will' appear from the following specification taken in connection with the drawings which form a part of this application, and in which:

Fig. 1 is a plan view of the blank used to make I the article of footwear embodying'the invention, this view showing the outer face of the blank; Fig. 2 is an elevational view of the blank folded to the proper position for placing on the last, this view showing the right side of the folded blank;

Fig.3 is a fragmentary elevational view showing the left side of the folded blank;

Fig. 4 is an elevational perspective view of the blank with its edges united and with the blank in position on the last and contoured thereto and sole and heel attached to the bottom of the inturned edges of the folded and contoured blank,

' the flap being shown open;

-Fig. 5 is a view similar to Fig. 4' but showing the flap closed; 1

Fig. 6 is a top plan view of the footwear shown in Fig. 5, parts being broken away;

Fig. '7 is a perspective view, partly broken away, showing a slight modification of footwear shoe in the usual manner.

The invention briefly described consists of a method of making an article of footwear, such as in, outline.

a boot, arctic, etc. formed of elastic or rubber material, the article having the heel, vamp and quarter,'including a ,closing flap, formed of a ,one-piece bla'nk of raw rubber. material, so designed and contoured that the back of the. article will be seamless and the edges of the blank will be folded to meeting position and joined at the front over the instep and ankle. The article is molded or contoured around a last and the heel andv sole are secured to the inturned bottom to complete the article of footwear and the article is vulcanized in the usual manner.

Further details of the invention will.. appear from the following description.

In the particular embodiment of the invention illustrated in the drawings, the blank shown in Fig. 1 is formed of raw or uncured rubber and is formed of one piece of material. This piece, for convenience in describing may be considered ascornprising a plurality of sections- The central portion comprises sections I II and I2 which form the quarters and heel. The inner edge of quarter I2 is indicated by the dotted'line 0-D and the outer edge of the quarter I2 is indicated by the dotted line A-B. I

Adjoining the quarter or section I2 at the outer edge thereof is an end section I3, triangular in outline, this section forming the closing flap of the boot or overshoe.

The blank has a downwardly extending elongated V-shaped opening or notch I4, the bottom of which forms the throat IA of the boot, and beyond the lower right end of .section II there extends a section I5 which forms, with the adjoining portion IIA of the section II, the vamp of'the boot. Section I5 is generally triangular Asealing fiap I6, the purpose of which is hereinafter described, extends beyond the right upper outer edge of quarter or section II at thenotch I4 7 Areinforced bead, rib or band I! is formed on or secured to the outer edge of section I3,

upper edges of sections I2 and II, and along the junction of flap I6 andsection II at the bottom of 'thenotch. [4 at the throat MA, asindicated by "A, and the bead also extends around the lower end of the notch I4, as shown at HB, for

' 'reasons hereinafter stated. 7

-- The sections II and I2 are divided at their lower ends by a V-shaped notch l8 forming edges l9 and 20 of heel sections 2| and 22. 'These sections have extensions or fiaps 23 and 24 adapted to be turned inwardly upon the breast of the closed and said lower corner area 25 thereof secured to the section I I, I IA.

of the vamp section I5. The portion of the lining 1 26 extending over the flap I6 is indicated on Fig.

2 at I6A. I

Figs. 2 and 3 show the blank folded on the line CD. When the blank has been so folded, the flap 5 is folded inwardly and secured by cementingits outer surface to the inner surface of the section l2 adjoining the closing flap l3.

The section 85 is folded on line E-F and the upper outer edge portion 15A of section 15 is cemented beneath-the lower edge portion 12A of section l2. The section l5 and the lower end or vamp portion HA of section H form the vamp of the boot or overshoe,

The folded blank, with the edges joined as above described, is then dropped over a lastL (see Fig. 4) and is contoured-thereto. The heel flaps 23 and 24 are inturned upon the breast of the heel of the article and cemented in the usual manner to form the heel or, if desired, the flaps may be dispensed with and the outer edges of the heels can be butt joined in the usual manner'and' the bottom edges inturned and cemented upon jthe insole. The other heel edges 19 and 20 are 1 also cemented or joined.

After the sole and heel have beencemented to the inturned bottom edges of the upper sections,

" the artlcleshown in Figs. 25'is inverted, thus leaving the, closure fiap 13 above the anchored 3 area 25 hanging parallel to the upper ll. I'he 1 article is so brought to the vulcanizer in accordance with thewell known procedure, thus preventing the lining of the flap l3 frombeing vulcanized to the upper l l,

' along the outer edge of bead portion HA, that is, at the junction of the flap l6 and section I I, thus releasing one upper from the other.

The invention and the use of a one-piece blank to form an elastic boot or article of footwear is not 'limited to low boots, as oxfords, or to high boots. The elimination of unnecessary seams,

joints, and reinforcements, provides uniform, un-

interrupted stretch, enabling the boot to fi-t snugly f-andoomfortably around the ankle and overthe instep. A high boot is shown in Fig. 'I. In this construction the sections H and I2 are extended fupwardly beyond the upper end of theflap I3 to .form suits. the two edg s of. the cuffs being. rein- 4 forced, as at llAand HC, 5 r

The boot is closed by a single fiapand fastener,

such as the snap fastener 33, .34 and the shape of the closure provides for a snug fit around theleg. Moreover, the low positioned throat MA at the bottom of notch l4 and the wide'openi'ng throat facilitates putting on and takingoff theboot and prevents tearing or ripping by the heel of the wearers shoe. Tearing at the base of the,throat is also prevented by the'reinforcing beading which extends around the base of the notch and throat and'by the reinforced area 25;

The back of the boot may be reinforced, if desired, by a strip 35, as shownin Fig. 6.

Although certain specific embodiments of the invention have been particularly shown and described it will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention, as expressed in the following claims.
