SLIPPER Filed May 1o, 195o BY 'usfazf Md M romyfrs Patented July 22, 1952 UNITED STATES PATENT OFFICE i SLIPPER Gustav Cohn, New York, VN. Y. Application Mayzio, 195o, serial No. 161,158

Claims.

This invention relates to a slipper, and more particularly Vto a lWashable slipperfhaving a crocheted upper provided lwith lacingfmeansanchored to the sides rof the sole ofsaid -shoe,rand wherein the'top sole, heel wedge, inner'and bottomLsoles are laminated to produce a unitary type of footwear. l n

In various types of footwear, particularly where the uppers are made of textile or fabric material,

it will be noted thatl the soles of said type offootwearare of such alquali-ty that in timethey deteriorate rather quickly. Also, such types .of footwear-become soiled very easily and cannot bewashed, with the result that withina short time they Aare discarded. Furthermore, the uppers -of-:said types of footwear arevusually made of canvas or other non-yieldable--materiaL While the lower `or foot resting portion is made'up of a-number of separate parts which, .uponwashing willfall apart. A n

In accordance with my invention, .it is desired to providewashable footwear having` a iiexible elastic upper adapted to provide a certainamount of elasticity wherebyY the footwear readilyoonforms to. the sibe and shape .of the ,foot of the wearer. l

It `is, accordingly, an object ofv this invention, to rprovide a vnovel 'type of easily assembled footwear whose parts are formed into .a unitary no nseparable iiexible product.

`Another, object of the present 'inventionis vto provide a .washable slipperhavin'g its component foot supporting parts laminated into va' unitary mass in which the sole and heel portion thereof arejindistinguishable one from the other.

One other objectY of the present invention is to provide a slipper having a crocheted lastex upper anchored to the marginal edge of the intermediate sole which in turn is fused to an inner and outer sole so as to form a unitary, integral slipper.

A more speciiic object ofthe present invention is vto,provide a washable Yunitary slipper Iin which the marginal edge of the inner sole is provided with a series of hidden or sealed holes having a chain or lock stitch. extending therefrom onto the marginal edge of the vsole to permit -easy anchoring thereto of a crocheted upper by means of `any suitable stitch, which'is adapted'to conform with the shape `and size of the foot of the wearer. n

Another object of the present invention is to provide a novel, economic `method of forming anchoring means in the sole ofaslipperl and of laminating the component part-s Ythereof 'to form A a washable type of slipper.

Further features and objects of the present (cms-9) invention willbecome apparent fromthe follow-v ing description taken -in connection with the accompanying drawings, inwhich:

Fig. l is-a side elevation of a preferred kembodiment of the present invention;

Fig. -2 isa plan partly broken vaway view of the bottom of the 'intermediate sole showing thetype of Astitching utilized for the purposes of ...anchoring a-flexible upper thereto 4as hereinafter described; 1 if Fig- 3 is a perspective fragmental detailedview of the portion shown in Fig. 2; y

Y Fig; 4 is a vfragmental detailed sectional; view taken on line 4--4 of Fig. ,1; and, i

Fig. 5 is a longitudinal Asectional Viewv .of-the I foot supporting portion of the embodiment prior to lamination of theparts'thereof.` 'Referring now moreparticularly to l,the `drawings in 'which similar reference ynumerals refer to `like parts throughout, .there is provided-a slipper II), having a hand-'crocheted upper 'IllA of any suitable style or design. The upper IIuis made preferably of anelastic lexibletype of fsynthetic Y n yarn.

footwear said upper -I -I is crocheted asia complete closed in United states. Patent 2,387,320 -lissued October 23 1945, inthe name of Foster, mixed Withnylon thread or'any other'suitable'textile In the manufactureof my newtype of unit preparatory toits yconnection to the lower laminated foot supporting portion I2. Said foot supporting portion -.I2 as shown in Fig. Y1 ofthe drawings .is made of `severalparts which are` laminated togetherin `any suitable manner either by. thermosealing or by cementing the same `*with anysuitable type of. adhesive material, such .as rubber cement. l

4It vwill be noted that foot supporting,.portion I,2pror to lamination,A as shown more specifically in Fig. 5, furthermore, contains 4an outside ortbottom sole I3, made of any suitableiie'xible material, ysuch as leather or ne0lite, an intermediate sole I4, a wedge heel I5 and an' inner sole I6, provided with a sock lining I 1 on its upper surface. Said intermediate sole I4, vwedge heel I5 and inner sole IBjare vpreferably `made `of a mixture of cork andrubber andlend themselves to easy laminationor thermosea'ling so as to form a unitary foot supporting flexible portion "I2, as shownmore clearlyin Fig. l. Prior to the lamination of said'par'ts, intermediate sole member I4` is perforated and provided with a plurality-of holes or openings I8 arranged 'in series alongfthe marginal edge yI 8 o'f said sole member I4. -Said holes `are--everily spaced alongthe periphery of saidsole member 3 I4 but are set inwardly of said edge sufficiently far to permit covering and sealing of said holes when forming the completed foot resting portion I2 and to be sealed from view when the sole is laminated. Furthermore, by means of said holes I8, an overedge chain stitch may be formed extending continuously and horizontally from the marginal edge I9 of the intermediate sole I4 as clearly shown in Fig. 3. This type of chain stitch providesV an anchor to which there is attached by means of thread or lace 2l the crocheted upper I I. The thread or yarn used to make chain stitch 20 may be of nylon or other suitable strong thread or fiber material which will resist wear and tear and continued washing.

In the process of making the slipper, the soles I3, I4, and I6 are initially swabbedwithrubber members are then laminated togetherby the application of heat and. pressure, whereby all of the parts are -welded so as to make an integral laminated foot supporting portion. After said foot supporting portion has been made the upper I I is then anchored to the chain stitch 20 in any suitable manner, for example as by an auxiliary stitching 2| Aas shown in Figs. land 4.

From the foregoing description taken in conjunction' with the accompanying drawings, it will be noted that by my invention a suitable flexible type of footwear can be made in three sizes; small, medium and large, particularly of the slipper type, thereby obviating the necessity of making slippers according to the exact footsize. Also, by making such types of footwear in the three sizes indicated, considerable savings in cutting according to different lasts is effected. By. the use of an upperl in footwear made according to the present invention, it will be noted that such upper has a certain amount of elasticity so as to conform with the shape-and size of the foot of the wearer. In other words, this type of footwear is adjustable to different foot sizes.

Furthermore, according to my invention, it will be noted that the anchoring means or chain stitch 20 protrudes from holes or openings I 8, and extends horizontally from the margin of the intermediate sole member I4 andis intermediate the inner and outer soles. 'Ihere is no danger of the chain stitch forming any contact with either the foot'of the wearer or with the surface upon which the wearer of the slipper walks. In addition, said type of stitch 20 forms a part of the laminated foot supporting portion, thereby eliminating any possibility of said stitching being broken. The openings I8 in intermediate sole I4 are not only hidden from view but are also filled due to the lamination of sole member I4 with sole members I3 and I5.

It will also be noted that a footwear made according to the present invention has long wearing qualities, does not readily deteriorate and can be easily washed without any breakdown of the ingredients of the foot resting portion. Nor will footwear made according to the presently disclosed invention crumble or fall apart when exposed to dampness or washed.

While a preferred embodiment of the invention has been disclosed, it will be noted that modifications as to arrangement of parts, use of materials and the procedure of their vuse may be 4. made without departing from the spirit and scope of the invention as claimed.
