Year: 1845

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SIMON
SNYDER, of the City of Dayton, in the State of Ohio, United States of
America, Mechanic, send greeting.
'
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Twenty-eighth day of June, in the ninth year of
Her reign, did, for Herself, Her heirs and successors; give and grant unto
me, the said Simon Snyder, my exors, adññors, and assigns, Her especial
licence, full power, sole privilege and authority, that I, the said Simon
Snyder, my exors, admors, and assigns, or such others as I, the said.
Simon Snyder, my exors, admors, or assigns, should at any time agree
with, and no others, from time to time and at all times during the term of
years therein expressed, should and lawfully might make, use, exercise, and
vend, within England, Wales, and the Town of Berwick-upon-Tweed, my
Invention of "IMPROVEMENTS IN TANNING HIDES AND SKINS ;" in which said
Letters Patent is contained a proviso, that I, the said Simon Snyder, shall
particular description of the nature of my said Invention, and in what
manner the same is to be performed, to be inrolled in Her said Majesty's
High Court of Chancery within six calendar months next and immediately
O after the date of the said in part recited Letters Patent, as in and by the
samé, reference being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Simon Snyder, do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, are particularly described and
ascertained in and by the following statement thereof, that is to say :-
The nature of my Invention consists in the preparation of the hides or skins
to be tanned by puncturing them with small holes partly through, or perforating
them with holes entirely through the hides or skins, either on the flesh or grain
side, so as to admit the tannin more freely and perfectly to penetrate and
operate upon the hide or skin.
The most proper time for performing this process of puncturing or per-
forating is when the hide or skin is in its most relaxed or reduced state, being
the last time it is worked out of the bate or grainer, and just before putting it
into the tan liquor; but it may be perforated at other stages in the cleansing or
tanning process. The punctures or perforations may be made either by hand
instruments, with a surface of steel points, to be applied, as before stated, either
to the flesh or grain side of the hide or skin, and made to penetrate either by
pressure or striking with a mallet, or by passing the bide or skin under or over
a cylinder or flat surface covered with steel points inserted at proper distances,
varying from one hundred to three hundred to the square inch, according to
the thickness of the hide or skin to be operated on by hand, water, steam, or
horse-power.
The principal advantages of my Invention are that hides and skins may be
effectually tanned in a much shorter space of time than in the ordinary mode;
that it will produce a better article of leather; that, the hides and skins
being made more susceptible of receiving the tannin, the liquor must be more
frequently renewed and so will be kept sweet; and that it saves bark or tanning
material; the expense of tannery in the number of vats and other fixtures
required, and will be altogether and in all other respects a cheaper process for
the manufacture of leather.
What I claim as my Invention is the preparation of the hides or skins to be
tanned by puncturing or perforating them either partly or entirely through, so
as to admit the tannin more freely, and perfectly to penetrate and operate upon
the hide or skin.
In witness whereof, I, the said Simon Snyder, have hereunto set my
hand and seal this Twenty-sixth day of December, in the year of our s
Lord One thousand eight hundred and forty-five.
SIMON (L.S.) SNYDER.
