Gloucester Gardens, Hyde Park, London, in the County of
Middlesex, for the Invention of "IMPROVEMENTS IN NAILS, SCREWS,

Scaled the 10th March 1876, and dated the 21st October 1875.
PROVISIONAL SPECIFICATION left by the said Thaddeus Hyatt and
Thaddeus Pomeroy Hyatt at the Office of the Commissioners of
Patents, with their Petition, on the 21st October 1875.
We, THADDEUS HYATT (Manufacturer of Patent Lights), and
THADDEUS POMEROY HYATT (Minor), of No. 66, Gloucester Gardens,
Hyde Park, London, in the County of Middlesex, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN NAILS, SCREWS, TACKS,
BRADS, SPIKES, AND HOOкs," to be as follows:-

page_text: tacks, brads, spikes, and the shanks of hooks in such manner as to
make them capable of being driven into wood or other substance like
ordinary nails, while yet possessing the function of screws, the
peculiarity of the Invention consisting in forming the nail or object
with one, two, or more uncut or unthreaded sides or sections, so as to
leave whole wood at the sides of those parts into which the screw
threads take when the nail or object is turned after it has been wholly
or partially driven into the substance. The thread upon the nail or
object thus made may be of any pitch as in ordinary wood screws.
These nails or objects have thus plain sides where no screw threads are,
and which are preferably paralel, and sides cut or made with threads,
and which sides are preferably tapering or wedge shaped.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thaddeus Hyatt and Thaddeus Pomeroy Hyatt
in the Great Seal Patent Office on the 15th April 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THADDEUS
HYATT (Manufacturer of Patent Lights), and THADDEUS POMEROY
HYATT (Minor), of No. 66, Gloucester Gardens, Hyde Park, London,
in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Mer
Letters Patent, bearing date the Twenty-first day of October, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Thaddeus Hyatt and Thaddeus
Pomeroy Hyatt, er special license that we, the said Thaddeus Hyatt
and Thaddeus Pomeroy Hyatt, our executors, administrators, and
assigns, or such others as we, the said Thaddeus Hyatt and Thaddeus
Pomeroy Hyatt, our executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all
times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN NAILS, SCREWS, TACKS, BRADS, SPIKES, AND

page_text: sides, so that when driven partly into the wood and then turned like a
screw they have the same holding power as an ordinary screw.
In witness whereof, we have hereunto set our hands and scals,
this 15th day of April, 1876.
THADDEUS HYATT.
