IMPROVEMENT IN STEEL SHANKS FORBOOTS AND SHOES. .i

TO ALL WHOM IT MAY CONCERN: g v -Be it knownthat we, HENRY BRINER .and EMIL BRINEP.,of'Manhattanville, in the county and State of New York, have invented a new and useful Improvement in Steel Shanks for Boots and Shoes; and we dolhereby declare that thefollowing is a full, clear, and exact description thereof', which will enable those skilled inthe art to make and use the same, reference being had tothe accompanying drawings, forming part of this specification. This invention relates to an improvement in the strips of spring-steel or other spring-metal called steel shank-s, for stiffening'the bottoms of boots and s-hoes under the hollow of the foot, or for supporting and lteeping in place that portion of theleather bottoms of boots and shoes. y

` And the invention and improvement consist in tipping or capping such steel Shanks with some metalor material which shall not springwith the steel, but'aecommodate itself to the form of the pieces of leather between i which it is confined. 4

Figurel is a side ,view of an ordinary full-sized steellshank, with our improved tip or cap attached. Figure 2 is an edge view of 'the'same A l Similar letters of reference indicate corresponding parts. A is the steel shank in ordinary use.

These shanlcs are m'ade 'of 'sheet steel, so cnt as to [it right'and left-hand boots and shoes, (o1- in pairs,) iig. l being for a. right boot, as indicated by'its shape. i

They l are curved or bowed upward, so as to correspond to the shape ofthe hollow of the'foot, or'to that part of the bottom of the boot, as indicated in iig. 2. v

The end marked B is'zfastened securely in the heel 'of the bootr or shoe, thc other end being left loose between the layers of leather, so as to allow of its springingjmorc or. less when the wearer iswalking.z The forward end being thus left loose, and suffered to work 'or move at every step, it receives from the springing of the steel' a' vertical motion, which penetrates and eventually wears through theleather, thus ruiningthc boot or shoe. j.'

This, very objectionable and damaging motion is unavoidable when' the steel lshank -is in one piece. To remedythe diiiiculty is the object of our invention.

For this purpose we attach a piece or cap of tin or copper, or anyother suitable mctalior material, to. the;` forward end of the shank, which shall n`ot`beY elastic, so as to be controlled by the spring ofthe steel, but whiehf shall adaptitself to the 'layers of leather, and he subjected by the spring oi" the steel te a slight longitudinal C is the cap 6r tip, which is simplyapiceof metal, doubled and-slipped on to the end of the ste'el","and riveted thereto, as seen'at d, or attached or connected to or with the steel in lany suitable manner.

It will be seen that this cap C projects outward or forward ofthe steel, and, not being elastic, it lwill accommodate itself to the leather vwithout vertical motion. A l

Wevdo not eonne ourselves to any particular form orvsiiefor the 4cap C.

. We claim as new, andvdesire to-secure by Letters Patent* As an improved article of manufacture, the steel shank for boots and shoreswhen its free end is provided with an inelastic case, C, for the purpose of preventing `injury to the sole of the boot or shoe by the longitl'idina1 motion produced by the`action of the spring, as herein shown and described.

The above specification of our invention signed by us, this 16th day'f April, 1868. v

lLdll'RY BRINER.
