PROVISIONAL SPECIFICATION.
Electric Boot and Shoe Grindery.
PERCIVAL PINCKNEY 151 Somers Road Southsea Hants Mechanical Engineer,
and I do hereby declare the nature of this invention to be as follows:-
-
The nature and object of this invention is to excite through the proximity of
electric energy thus applied, a freer circulation of blood through, and hence
produce an increased degree of vital warmth and muscular development in the feet
and legs of those persons who shall adopt to wear them.
This claim is to be taken as having no reference whatever to the tools used in the
trade, or to anything outside the special limit for which protection is sought,
namely for tips, plates, nails, protectors rivets brads and all other articles of
grindery which are actually worn upon or inserted in the soles and heels of boots
and shoes, and likewise to such articles of grindery as are subsequently renewed or
replaced in consequence of wear.
The invention for which protection is hereby claimed consists in placing articles
of boot and shoe grindery in combination with some other metal or metals. Or
with some other substance, or substances. But always so that the whole
combination becomes a miniature voltaic electric battery. That is to say the article
of grindery by being made a constituent part of such combination-becomes
contributory to the generation and transmission of voltaic electricity.
The main feature of my invention, and the one for which I claim special and
comprehensive protection is my novel device of using what shall be henceforth
named and referred to in connection with this Patent as voltaic electric battery
plates which are to be used in combination with boot and shoe grindery.
These said battery plates for boot and shoe grindery may consist of plates or
other shaped pieces of copper or zinc-or of other metal or metals.
Or they may be made of any suitable, that is to say any electrical generative
substance or substances, whatsoever.
And the said battery plates are to be placed upon or in proximity to the
backs or parts most removed from wear-of the tips, plates, nails, protectors, and
other of the larger articles of grindery in such a manner, arrangement, and
O combination with such articles of grindery so that the whole combination will
generate voltaic electricity.
The smaller, or any other part or parts of my invention which it may be found
advantageous so to do may either be metal cased or treated by the process known
as electro-metallurgy.
Or the same electrical effect may be produced by alternately inserting in the
soles and heels: brads rivets or other similar articles of grindery which are severaly
and respectively made purposely of dissimilar metals.

Electric Boot and Shoe Grindery.
1, PERCIVAL PINCKNEY 151 Somers Road Southsea, Portsmouth Hants,
Mechanical Engineer do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
5 in and by the following statement :-
The nature and object of this invention is to excite through the proximity of

page_text: electric energy thus applied : a freer circulation of blood through, and so induce
an increased degree of vitality, and muscular development in the feet and legs of
those persons who shall adopt to wear them.
These claims are to be construed as not refering to the tools used in the trade.
Neither to anything outside the special limit for which protection is sought.
Meaning that the said protection is only to include-tips, plates, nails, protectors,
rivets, sparrow-bills, brads, and all the other articles of grindery which are worn
upon, or inserted in, the soles and heels of boots and shoes.
The invention for which protection is hereby claimed, consists in placing articles
of boot and shoe grindery in combination with some other metal, or metals; or with
some other substance or substances. But always so that the whole combination
becomes in the aggregate a miniature electric battery. That is to say each article
of grindery by being made a constituent part of such combination becomes
contributory to the generation and transmission of electric energy.
The main feature of my invention, and the one for which I claim special and
comprehensive protection, is my novel device of using what shall be henceforth
named and refered to in connection with this invention, as electric battery plates,
and which electric battery plates are to be used in combination with the larger
articles of boot and shoe grindery.
These said electric battery plates for boot and shoe grindery, consist of plates, or
other shaped pieces of copper or zinc, or other metal or metals.
Or they may be made of any suitable, that is to say any electrical gencrative
substance, or substances.
And the said electric battery plates are to be placed upon, or in proximity to
the backs, or parts most removed from wear, of the tips, plates, nails, protectors,
and other of the large articles of grindery, in such a manner, arrangement, and
combination with such articles of grindery, so that the whole combination thus
produced will generate electricity, by what is sometimes differently termed either
as galvanic, voltaic, or chemical action.
To increase the electrical action the following other excitant may be added. A
piece of absorptive material such as paper or calico is dressed with vinegar, cyder
or other acid, from the material thus prepared pieces are cut of the same shape
as, and their purpose being to be placed upon and used in conjunction with the
electric battery plates as hereinbefore described.
TREATMENT OF THE SMALLER ARTICLES OF GRINDERY.
The smaller articles of grindery may be made severally and respectively of
dissimilar metals. That is to say the brads, or rivets, for instance, may be made
some of, say copper, and some of,-say zinc. Or the brads and rivets now in
ordinary and general use and now made some of brass and some of iron-(and
which howsoever they may be placed in contact or proximity one with the other
will not generate electric action) may be cased or plated with other and dissimilar
electric-generative-metals. So that when inserted and worn in the soles and heels
of boots and shoes, their metallic dissimilitude and proximity one to the other shall
be such as will cause the generation of precisely the same electrical effect (to the
wearer) as is caused by the larger articles of grindery. In the manner and by the
means as herein before described.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is.―
1. Relates more specifically to the larger articles of grindery. The sole and
exclusive right to make and to use the said electric battery plates, as herein before
described, in and for the manufacture of a combination which shall be named and
known as electric boot and shoe grindery.
2. Relates more specifically to the smaller articles of grindery. The sole and

page_text: exclusive right to make and to treat the smaller-or any-articles of grindery in
the manner herein before described. And which smaller articles after being
subject to such treatment as herein before described shall be named and known as
electric boot and shoe grindery.
3. The sole and exclusive right to excite in the soles and heels of boots and shoes
an electrical effect, by the means, in the manner, and for the 'object, as herein before
described.
4. The sole and exclusive right to use in the manufacture of, or in combination
with boot and shoe grindery, such and such dissimilar inetals as will with, or without
other excitant, produce when worn in the soles and heels of boots and shoes,-an
electrical effect.
5. The sole and exclusive right to render tips, plates, nails, protectors, brads,
rivets, sparrow-bills, and all other articles of boot and shoc grindery as, worn upon,
or inserted in, the soles and heels of boots and shoes; capable of generating
electricity, by such means, processes, and treatment as herein before described.
