METALLIC RUBBER snon COMPANY, or nauoarucx, connncrxcn'r, A oonrone V TION OF CONNECTICUT RUBBER FOOTWEAR Application filed June 4, 1928, Serial No. 282,707.

g This invention relates to an article of'rpbber footwear, especially to boots and bootees. The present type of rubber footwear or bootee has a toe portion which is of uniform thickness and strength throughout.

type of footwear does not provide protection to the wearer against shocks or blows on the toe.

It is an object of this invention to provide an article of footwear such as a bootee having a toe portion so constructed as to provide a tip which will protect the wearer from blows. It is a further object of this invention to so strengthen the tip of a bootee or similar article as to provide a toe non-crushable under ordinary service blows. A further object of this invention is to increase the strength of the toe of an article of rubber footwear.

With the preferred form of the invention shown in the drawings in mind and without intending to limit the invention more than is required by the prior art. the invention broadly consistsin providing. the tip of an article of rubber footwear with \a relatively thick 26 tough and form retentive layer of rubber composition which will serve to absorb shoc s and strengthen the tip against crushing and/or lacerating. r

A preferred form of the invention is shown in the accompanying drawings in which:

Fig. 1 is a side elevation of a bootee with the toe portion in section.

Fig. 2 is a plan viewof the toeportion of the bootee. Referring to the drawings the bootee has a sole 1 of a suitable rubber composition and a rand 2 of like composition. A thin sheet of rubber 3 serves to connect the sole. 1 and the insole of the bootee. The insole 1s comprised of two layers 4 and 5 of rubber composition superimposed upon WlllCll 1s a sheet 6 of fibrous material. The upper of the shoe consists of the rubberized fabric 8 superimposed upon a layer of fabric 7. The edge of 45 the layer of fabric 7 extends between the two layers 4 and 5 of the insole so as to create a firm union between these elements. The edge of the layer of rubberized fabric 8 extends into contact with the layer of rubber 3 and the rand 2. A faxing 9 serves to interconnect Suchthe upper of the shoe with the rand and sole. The bootee as so far described is of conventional construction. 7

' In order to strengthen the tip of the shoe a cup shaped sheet of rubber compound such 5:5v

as rag rubber extends between the layer of fabric 7 and the layer of rubberized fabric 8 and around the tip of the shoe. This sheet 10 is of relatively considerable thickness as compared with the layers 7 and 8. The sheet 10 is of a tough resilient material and as the result of its characteristics, the relatively great thickness and its position in the toe of the boot it provides protection to the wearer as blows from heavy hard articles and also serves to guard against any laceration such as would occur if a sharp edge object struck the toe of an unprotected boot.

The laminated article as described is'assembled upon a last and vulcanized so as to firmly unite the various elements of the structure.

As will occur to those versed in the art othermaterials may be'used in making the cup shaped sheet 10. Also the extent of the protective sheet 10 may be increased to cover" more than the tip portion of the shoe.

In its broad aspects the invention consists in providing in the tip of a shoe a sheet of material which will strengthen the toe so as to provide protection against shock and/or laceration.

For an understanding of the scope of the invention reference should be made to the following claims.

Having thus described my invention, what I claim and desire to protect by Letters Patent is: Y

1. A rubber bootee having an upper composed of an outer layer of rubberized fabric and an inner layer of fabric, and a toe reinforcement between said layers and extendin only over the top and around the front an the side portions of the toe, said reinforce.- ment consisting of a tough rubber composition relatively thick as compared to said 'layers whereby protection against blows and cute is provided for the wearer.

2. A rubber bootee having an upperc'om posed of an outer layer of rubberized fabric and an inner layer of fabric, and a toe rein forcement between said layers and extending only over the top and around the front and the side portions of the toe with wing portions which extend along the side portlon of the toe, said reinforcement consisting of a tough rubber composition relatively thick as compared to said layers whereby protection against blows and cuts is provided for the wearer.

10 Signed at Naugatuck, county of New Haven, State of Connecticut, this 23rd day of May,- 1928.

JOHN W. CLIFFORD.
