Patented June 2Q, 1944 SHOE R SIIVHLAE ABTIGLE William H. Joyce, Jr., Pasadena, Calif., a-signor to Joyce, Inc., Pasadena, Calif., a corporation of California Application April 22, 1942, Serial No. 440,066 4 Claims. (01. 36-195) This invention relates to footwear and particularly an improved construction of, a shoe having the basic characteristics disclosed and claimed in my United States Letters Patent No. 2,067,963, granted January 19, 1937, and is an improvement thereon. i

In this type of shoe or slipper construction there is provided an upper, the lower edges of which are turned inwardly and secured to an insole, a midsole member of relatively thick cushioning material shaped to extend complete- 1y over the surface of the insole and comprising a sole portion of substantially constant thickness and a heel lift portion tapering in thickness from the shank of the shoe or slipper to provide a substantially smooth lower surface to said midsole member and provided with a covering of relatively thin material extending about the edges of the midsole member, such midsole member is secured to the lasted upper and insole, and an outsole membercoextensive with the midsole member is attached to the lower surface of the midsole member. Shoes or slippers of the character described have been widely manufactured under said patent and sold underthe trade-mark COOL-EES.

While from a manufacturing standpoint, there are various advantages in manufacturing shoes of such character by the cement process, a possible shortage or lack of cement for the purpose may handicap such production, and I have also found that certain advantages may be realized by the stitching of some of the parts.

I have therefore devised a modified and in certain respects improved construction for achieving what in external appearance is the same shoe as that disclosed in my aforesaid patent, and while in basic structural elements is the same,

embodies some differences in detail which are found to be improvements.

It is an object of my present invention to provide in avshoe or slipper of the character described an upper with the lower edges thereof turned under and secured to the lower marginal portions of an insole, a midsole member comprisin! a pad of cushioning material which is adapted to overlie the entire area of the insole and is provided with an edge covering of fabric, leather or-other material, the pad being stitched through to secure it to the insole. The stitch-v ing may pass through at least the upper intumed edges of the covering, and a heel raise or lift inserted in a pocket formed by leaving the middle and lower portions of the covering around being thereafter wiped in upon the heel lift, and an outsole then secured to the lower surface of the completed midsole. Variations of this general construction and additional details thereof are contained in the subsequent description, from which additional objects, and advantages will be apparent. For example, in the form shown in Figures 7 and 8, the stitching securing the pad to the insole does not necessarily pass through the cover.

In the drawings:

Figure 1 is a perspective view-of a cushioning pad with an edge covering around the toe portion.

Figure 2 is a view of the'same pad with the edge covering around the heel portion attached and left open to form a pocket for a heel lift.

Figure 3 is a vertical sectional view of a shoe on the last, made according to' my invention and with the cushioning pad of the midsole at-- tached to the lasted upper.

Figure 4 is a view similar to Figure 3 showing the heeLpad cover turned up to facilitate stitching operations and the assembly of the heel lift.

Figure 6 is a vertical sectional view similar to Figures 3 and 4 showing the shoe completed on the last.

Figure '7 is a perspective view of a modified form of attachment of a heel edge covering for the midsole. Figure 8 is a cross sectional view taken on line 8-8 of Figure 7-.

Figure 9 is a view similar to Figure 2 illustrating a modified form of pad cover made in one piece.-

Figure 10 is a fragmentary sectional view of a modified form of heel construction embodying a wooden dowel.

Referring to Figure 1, a cushioning pad I0 is preformed of felt, fiber, sisal, rubber, cork, composition, or any other suitable resilient cushioning material, preferably flat and sufliciently thick the to impart a cushioning effect to the shoe or slip-- per, and cut to substantially conform-with the shape of the bottom of the last. A hole in the heel for a wooden dowel or holes for any other -heel reinforcing elements desired may be provided, but are not illustrated as they are wholly optional in the practice of my invention, and

the heel region loose, the marginal lower edges such modification is shown in Figure 10.

of the pad. I prefer to attach this strip II by means of stitching, although adhesives may be used. It is preferable that both upper and lower edges be thus attached, although it is within the scope of my invention to attach the upper marginal edge only, allowing the lower edge to remain open and be either stitchedor cemented and wiped in at the same time as the cover around the heel portion is wiped in, as subsequently described. It is possiblelto practice my present.invention by using paste or some inferior or temporary adhesive forsecuring the edge covering l I upon the forepart of the pad Ill- The next step in the preparation of the midsole is to stitch or cement a heel edge covering strip I! to the pad III with the upper marginal edge of the covering l2 overlying the marginal edge surface of the pad and overlapping the ends of the covering member ll. Inasmuch as the heel covering strip I2 is to be left open, it is easier to stitch it on the pad than to cement it. For convenience of illustration, I show the heel edge covering turned down in Figures 2 and 3, but it is preferable at this stage of manufacture, to retain the heel edge covering turned up, as shown in Figure 4, as the placement of the heel lift subsequently described is thereby facilitated.

In the form shown in Figure 9, the pad covering Ila comprises a single piece of material, joined at a single lap I lb. Except for the use of a single piece of material, the other operations employing this form may follow the optional methods de-' scribed in reference to the form shown in Figllre 2.

Theupper and insole have been previously prepared in accordance with the disclosure of my aforesaid Patent No. 2,067,963, comprising an upper IS the lower edges of which are turned under and secured to the lower face of an insole I4. Preferably while the upper remains upon the last IS, the pad prepared as previously described, is spotted for location. The partly assembled shoe is then taken of! the last and the pad is attached by sewing or cementing, or partly sewing and partly cementing, or by other means.

The shoe is then put back on the last, and a heel lift it positioned by cement, paste, stapling or any other suitable manner. The heel lift is preferably wedge shaped as illustrated particularly in Figure 6, so that it fits against the upward curved portion of the arch and heel portion, providing a substantially flat lower surface for the outsole member. However, there is no objection to shaping the midsole with an arch or cut out on the lower side, in which case the outsole would be made to conform to such alteration. The heel lift it may be of a cushioning material similarto that employed for the pad III or it may be of a. different material, and it may be also made of wood, or

other non-resilient material. It is not required that the heel lift it be of a resilient or cushioning material, inasmuch as the Dad I is alone ade- The heel flap l2 then is pulled down around the heel lift, and the lower edges turned in, stapled, or otherwise secured to the lower marginal surface of the heel lift, completing the covering of the midsole member, as shown particularly in Figure 6.

A substantially flat outsole I8 of durableleather, rubber'or. other suitable material is then attached to thelower surface of the midsole by cementing or any other desirable attaching means. As before stated, if the midsole is formed with an arch or cutout, the outsole should conform thereto.

A conventional sock lining (not illustrated) may be placed on the insole, this being a matter of choice.

In the modified form shown in Figures 7 and 8 the diflerence lies in the exact manner of attaching the edge cover strip in to the heel portion of the pad. Here the said cover is stitched to the upper surface of the pad with the outer edge of the cover following the contour of the edge of the pad; instead of the edge being turned in, and the cover is then folded back on itself, as illustrated, to form a pocket for the heel lift.

It is to be understood that the cover if of Figure 2, and i 2a of Figure 7 may be cemented to the upper surface of the pad instead of being stitched thereto but I consider it better practice when regarding the present construction as a whole to stitch the edges, in one of the ways indicated.

A shoe or slipper may be constructed according to the disclosure and limiting the need for a permanent, high grade cement in attaching the edge covering to the pad member, enabling the use of an inferior type of cement or paste, it eliminatesthe need for 'roughening the top of the pad along I .the marginal turned in edges of the midsole covering (an operation sometimes necessary when cementing the midsole to the upper), the midsole in the present construction being attachable to the upper by stitching, thereby also eliminating the necessity of cement for attaching the midsole toithe upper.

:Although I have herein shown and described my invention in what I have conceived to be the most practical and preferred embodiment, it is recognized that departures may be made therefrom within the scope of my invention, which is not to be limited to the details disclosed herein but is to be accorded the full scope of the claims so as to embrace any and all equivalent structures and methods. Other variations, not described, may be practiced within the'scope of my invention.

The essence of my invention is a shoe or slipper construction wherein an upper is lasted with its lower edges turned in and secured to the lower surface of an insole, a midsole is attached to the aforesaid lasted upper, the midsole and manner of attaching it comprising a pad having an edge covering at least the heel portion of; which is leftopen, then spotting it to the bottom of the upper and, stitching through the pad; the inturned lower; edge of the upper, and-the in; sole, or by otherwise attaching .the padto-the upper, a heel lift is positioned against the under surface .of the heel portion of the pad, and the quate for that function. (If it is desired to form a .7

hole in the heel lift in line with a hole in the heel. portion of the pad I! for the insertion of a wooden dowl 20, this may be done within the spirit of my invention, as for example, shown in Figure 10.)

covering theretofore left open is brought against the heel, lift, and the lower edges secured around the lower marginal surface of the heel lift, and an outsole is attached to the-lower surface of the midsole thus formed. a l Having described my invention, what a I- claim as new and desire to secure by Letters Patent is:

cured thereto, a midsole substantially coextensive with the area of the insole and secured to the upper, the midsole and means of attaching it to the upper comprising a preformed pad of cushioning material, an edge covering of material around the toe portion of the pad with the upper and lower edges of the covering turned in over the upperand lower surfaces respectively of the pad and stitched through said pad, an edge covering of material around the heel portion of the pad wide enough to also cover a heel raise and secured against the upper surface only of the heel portion of the pad, the pad being stitched through the body thereof a second time and through the inturned lower edge of the upper and the-insole to attach the midsole to the upper, a heel lift positioned against the lower surface of the heel portion of the pad, the edge covering around the heel lift being turned down around same and the lower edges turned in and secured to the lower marginal surface thereof, and an outsole attached to the lower surface of the midsole.

2. A shoe or similar article construction as described in claim 1, in which the cover for the heel portion of the midsole is stitched to the upper surface of the pad with the edge of the cover turned outwardly, and the cover is turned over itself outwardly in enclosing the heel lift.
