IMPROVEMENTS IN CRIMPING MACHINES
Year: 1854

page_text: LETTERS PATENT to Alfred Tylor, of Warwick Lane, Newgate Street, in
the City of London, for the Invention of "IMPROVEMENTS IN CRIMPING
MACHINES."
Sealed the 13th February 1855, and dated the 21st November 1854.
PROVISIONAL SPECIFICATION left by the said Alfred Tylor at the Office
of the Commissioners of Patents, with his Petition, on the 21st November
1854.
I, ALFRED TYLOR, of Warwick Lane, Newgate Street, in the City of London,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
CRIMPING MACHINES" to be as follows:-
Heretofore the bearings of crimping machines have been made of metal,
and the journals of the rollers being of metal also, a serious amount of wear
has always ensued to the journals of the rollers from the metal bearings cutting
or tearing them in use. Now, my improvements consist in substituting bearings
of wood for the journals of the rollers to revolve in, instead of, as heretofore,
metal bearings. By this arrangement I preserve the journals of the rollers
from being cut or tore, as in the case of metal bearings; and the wood bear-
ings, being a non-conductor of heat, I confine the heat (so necessary to the use
of the machine) entirely to the rollers, instead of, as heretofore, being dispersed
over the whole of the framework of the machine-And-my-improvements-also

page_text: consist in the mode of applying the pressure to the rollers for the purpose of
crimping, which has been heretofore by a single spring, or two springs acted
upon by set screws. Now, my improvements consists in employing four springs
so arranged as to obtain an equal pressure at all points of the bearings.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alfred Tylor in the Great Seal Patent Office on the 21st May
1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
TYLOR, of Warwick Lane, in the City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of November, in the year of our
Lord One thousand eight hundred and fifty-four, in the eighteenth year of Her
reign, did, for Herself, Her heirs and. successors, give and grant unto me,
the said Alfred Tylor, Her special licence that I, the said Alfred Tylor,
my executors, administrators, and assigns, or such others as I, the said
Alfred Tylor,, my 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
CRIMPING MACHINES," upon the condition (amongst others) that I, the said
Alfred Tylor, by an instrument in writing under my hand and seal, should
particularly describe and ascertain the nature of the said Invention; and in
what manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Alfred Tylor, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
Heretofore the bearings of crimping machines have been made of metal,
and the journals of the rollers being of metal also, a serious amount of wear
has always ensued to the journals of the rollers, from the metal bearings cutting
or-tearing-them,-the-rollers-being-too-hot-while-in-use to-be-lubricated._My
improvement consists in having the bearings of wood instead of metal for the
'rollers to revolve in. By this arrangement I preserve the journals of rollers
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-

page_text: from being cut or tore, as in the case of metal bearings, and the wood, being
a non-conductor of heat, the heat is confined entirely to the rollers, instead of,
as in the case of metal bearings, dispersed over the whole of the framework
of the machine. And my improvement also consists in the mode of applying
the pressure to the rollers for the purpose of crimping, which has been here-
tofore by a single flat spring, or by two small springs, made of flat steel, and
acted upon by set screws in centre of bearings. Now, I apply four spiral
springs, by which form of spring I obtain a greater amount of elasticity, and
thereby prevent the rollers from cutting the material that has to be passed
through them for the purpose of being crimped, and the springs being placed
as shown in the Drawings, at the four outer points of the bearings, I obtain
elasticity with steadiness.
Having thus stated the nature of my improvements, I will now proceed to
describe the Drawings, and the figures and letters marked thereon.
Figure 1 is an elevation of a crimping machine with my improvements
attached; Figure 2, a plan of do.; Figure 3, an end view of the same. A, A,
are the rollers of an ordinary machine; B are the bearings of wood; C, C, C, C,
are four rods of iron, affixed in frame D, which pass through the bearings B,
and of sufficient length to receive the spring E over it, terminating with a
screw for the nut F to screw on, for the purpose of adjusting the bearing B;
G is the handle by which machine is worked.
Having thus most fully stated the nature of my improvements, and the mode
of performing the same, I would have it understood that what I claim is,
having bearings of crimping machines of wood, and the mode described of
adjusting the same, as in respect to Figures in Drawings No. 1, 2, 3.
