RUBBER SOLE-FRGEELTQE BJGTS AND SE13.

To (ZZZ whom may condemns:

Be it known that l, Eocene FULLER, citizen of the United States, residin 'et Providence, in. the county of Frovi once and State of Rhode island, have invented.-

edge part of the sole proper and terminates at the shank portion; and having the half sole member provided with means for mainmining it in position on the sole, and further, having a yieldable packing positioned soas to exclude or prevent the entrance of water between the adjacent surfaces of the sole and helfsole members, all as more fully hereinaiter set forth and claimed.

The object 1 have in view is toprovide a simple, connect, inexpensive, easily and quickly applied article of footwear, which may be termed a detachable rubber ball"- sole, adapted to protect the bottom of the usual more or less pervious sole portion of boots and shoes from contact with wet or moist surfaces and thus prevent the absorption. or penetration oi moisture therethrough, while at the same time in no wise interfering with the usual ventilation or circulation or air through the upper portion or such boots and shoes. l

In order to increase the durability and eificiency df the device, I prefer to make its normal form in a. long tudinal direction such that in applying it to the sole of the shdeit will necessarily be flattened somewhat, thereby, too, increasing its resiliency and holding capacity, and also producing a smallair 'space of cushioning chamber between the adjacent surfaces.

In the accompanying sheet of drawings, Figure 1 represents a partial side elevation of a shoe, showing (sectionally) my improved rubber sole-protector removably attached to the sole thereof, as in use. F ig. 2 is a side elevation of the device, as a whole, detached from the shoe. Fig. 3 is a correspending top plan view. Fig.4 is a longitudinal sectional view, in enlarged scale,

again referring to the rewings, desighates the invention or e-rticle of manufacture as a whole, which me be termed an impervious, resilient hel sole, adapted to be detachably secured to the usual sole proper, o, of a boot or shoe, and having its rear end provided with a suitable clasp or clamp, as c, or other analogous holding ineans, c0nstructed to engage the usual shank portion, e, integral with said sole part e. The said half-sole member is quite shallow, and preferably made from rubber or a composition of rubber, molded and vulcanized in any suitable or well-known manner; its normal form being substantially as represented in Figs. 2

and 3. Thesole'part, a, is or may be pram-- tically uniform in thickness throughout, and provided with an inner lined surface and roughened outer bottom surface, substantially as employed in rubber overshoes, and (which is very importent) is advantageously of abnormal, i. 0., deep curvature (as clearly ,shown in Fig. 2). l'have discovered by ex- "periments and tests that, by constructing the sole (2 .with said abnormal curvature, the following advantages accrue: (l), When the half-sole is-in use on a shoe'sole, the abnormal. curvature permits the formation of an air'chamber s between the half-sole and the shoe-sole, which prevents sweating of the foot, inherent in the use of half-soles and rubber overshoes of ordinary construction, and (2) the bead a will, in use, be caused to adhere more snugly to theupper edge of the leather sole. The outer peripheral edge of the sole or is extended upward and forms a. comparatively thin, narrow side wall, a, terminating at the top in an inwardly projecting beaded or thickened free edge part, a thelatter being shown sectionally in Fig.

Fig. 5 is a front r; and

1. The rear end portion of member A isv adapted to engage the shank or arch part, a of a shoe, and is provided with a norm pressible, transverserib or packing member;.

The member a? has a slot through which the pin (i esiuends,

and a plurality of siining hoies, 1 ecizipres to receive said lug 0.

Upon releasing the tongue the member (Z springs back upon the base, its Mg 0 then entering she correspending belie 71, thus leaking the te-- gether in the adjusted posi'cien.
