Patented Oct. 11, 1938 PAT NT OFFICE RUBBER OVERSHOE v Charles F. Berry, Boston, Mass. Application August 6, 1936, Serial No. 94,503

4 Claims.

This invention relates to rubber shoes and has for its object the production of a shoe which may be extended lengthwise to fit'various lengths of leather shoes on which said rubber shoes are worn.

Another object of the invention is the provision of means whereby the fore part of the rubber shoe may be adapted to fit various widths of said leather shoes.

These objects are attained by the construction of the rubber shoe illustrated in the accompanying drawing.

For the purpose of illustrating'the invention, one preferred form thereof is illustrated in the drawing, this form having been found to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized, and the invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described except as required by the scope of the appended claims.

Of the drawing:

Figure 1 represents an elevation of a rubber shoe embodying the principles of the present invention.

Figure 2 represents a vertical section of the fore part on line 2, 2,011 Fig. 1.

Figure 3 represents a vertical section on line 3, 3, on Fig. 1.

Figure 4 represents a plan of the member for uniting the fore part and heel part of the shoe.

Figure 5 represents a section on line 5, 5, on Fig. 1.

Figure 6 represents a similar section of a modification, and

Figure 7 represents a section on line 2, 2 on Fig. 1, and showing a modification of the structure shown in Fig. 2.

Similar characters indicate like parts throughout the several figures of the drawing.

In the drawing, i0 is the fore part of a rubber shoe, the heel part I l of said shoe being separated from the fore part by a gap i2, said parts in, II being of non-stretchable rubber such as is usually employed in the manufacture of rubber shoes.

This gap 12 between the two parts W, H of the shoe is covered by a sheet i3 of elastic rubber which unites the two parts IB, H, at the same time permitting limited end movement of. the two parts relatively to each other, so that the rubber shoe may be made to fit various lengths of leather shoes on which the rubber shoe is to be worn.

The sheet l3 may be in the form shown in full lines in Fig. 4, the central part M thereof extending under the instep where it will never be sub- J'ected to wear by the surface on which the wearer may be travelling.

Sometimes in purchasing the same size of 5 leather shoes of different makes the lengths will vary but with the rubber shoe herein shown and described such rubber shoe may be stretched to fit various lengths of leather shoes.

Furthermore, it sometimes becomes necessary for a person to commence wearing a slightly longer leather shoe or one in which the sole is longer, and in such a case the rubber shoe. does not need to be discarded but may be adapted for use on the longer shoe.

-Moreover, where different persons in a home wear leather shoes of different lengths, the same rubber shoes may be used by any one of these persons.

The sheet i3 is vulcanized to the outer surfaces of the sides and soles of the fore part If! and heel part II and its outer surface is made to conform to the outer surface of both fore part and heel part in color and finish.

If desired, the sheet I3 may have at each end 5 an extension i5 as shown in dotted lines in Fig. 4, and these extensions may be passed over the upper edges it of fore part if! and heel part II and secured to the inner surfaces of the sides and soles of .these parts, as indicated at IT in Fig. 3.

Sometimes the width of the fore part IU of leather shoes will vary in width and in order to accommodate the rubber shoe to these various widths an elongated gash i8 is cut through and lengthwise of the side walls i9 of the fore part It] and substantially parallel to the sides thereof, and these gashes l8 are covered with sheets 28 of stretchable rubber whichare vulcanized to the outer surfaces of the walls IS! with the outer surface of said sheet conforming in color and finish to the outer surface of the body portion of said fore part.

The sheet 20 may be applied to the outer surface only, as shown in Fig. 2, or if desired additional sheets 2| may be secured to the inner faces of the side walls i9 and secured thereto, as shown in Fig. '7, thereby covering the gash or opening [8.

By the construction of rubber shoe herein shown and described said rubber shoe may be 50 extended to fit various lengths of leather shoes which is obviously a great advantage.

Another advantage is that owing to the elasticity of the sheet 13 the part 22 of the heel part may be more readily drawn over the heel of the leather shoe, and when once on, the pull of the elastic sheet [3 will cause the part 22 to grip firmly on the heel of the leather shoe and prevent it from becoming displaced accidentally.

It is believed that the many advantages of a rubber shoe so constructed as to fit various lengths and widths of shoes will be fully apparent and require no further description.

Having thus described my invention, I claim:

1. A watertight rubber overshoe in which the fore part and heel part are distinct units of nonstretchable rubber separated at the instep by a narrow gap and connected together by an im-' pervious stretchable elastic rubber sheet having an unbroken plane surface whereby said units are movable endwise relatively to each other by the stretching of said rubber sheet.

2. A rubber overshoe having an elongated narrow opening extending lengthwise of a side wall of the fore part upper and substantially parallel to the sole thereof and a sheet of impervious stretchable elastic rubber material covering said opening and hermetically secured to the outer surface of said side wall.

3. A rubber overshoe having an elongated narrow opening extending lengthwise of a side wall of the fore part upper and substantially parallel to the sole thereof and. sheets of impervious stretchable rubber material covering said opening and hermetically secured to opposite faces of said side Wall.

4. As a new article of manufacture a watertight overshoe, the fore part of which is made of non stretchable rubber with an opening therein adjacent the sole and is provided with impervious elastic means over said opening to permit the widening of the forepart immediately above the sole thereof in order to fit various widths of leather shoes over which it may be worn.
