page_text: LETTERS PATENT to Samuel Turner, the younger, John Turner, and
Robert Turner, all of Rochdale, in the County of Lancaster, for
the Invention of "IMPROVED MEANS FOR SECURING THE JOINTS OF STEAM
AND WATER PIPES. AND FOR OTHER SIMILAR PURPOSES.”
AND WATER PIPES.
AND FOR OTHER SIMILAR PURPOSES.'
PROVISIONAL SPECIFICATION left by the said. Samuel Turner, John
Turner, and Robert Turner at the Office of the Commissioners of
Patents, with their Petition, on the 18th September 1875..
We, SAMUEL TURNER, the younger, JOHN TURNER, and ROBERT
TURNER, all of Rochdale, in the County of Lancaster, do hereby declare
the nature of the said Invention for "IMPROVED MEANS FOR SECURING THE
JOINTS OF STEAM AND WATER PIPES, AND FOR OTHER SIMILAR PURPOSES," to be as
follows:--
-
This Invention relates to the flat rings or washers of india-rubber or'
other suitable elastic material or composition, such as are used for
placing between the flanges of pipes to form a steam, water, or air-tight
j

page_text: joint, and the object of the Invention is to strengthen such rings or
washers and increase their power of resistance without detracting from
the flexibility or elasticity of their surfaces which form the joint.
The Invention consists principally in combining with such flat india-
rubber or other elastic rings or washers strengthening-rings-of-metal-of-
-a-tough-like-section applied (by preference) to their outside circumference
but the metal rings may, if thought desirable, be applied to their inner
circumference or edge, or even to both edges thereof.
These metal strengthening rings form as it were a rim or ring with
two narrow flanges projecting from its inner edges, if the ring is to
be applied to the outside of the washer, or from its outer edges if the
ring is to be applied to the inside of the washer; and the edge of the
india-rubber washer is to be embraced and held from between these two
flanges. The india-rubber or other elastic material is thus prevented
from 'expanding laterally by undue pressure, at the same time, that
owing to the narrowness of the flanges, the greater part of the india-
rubber or other elastic surface is. left exposed so as to form the steam,
water, or air-tight joint in as efficient a manner as heretofore.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Turner, John Turner, and Robert Turner 20
in the Great Seal Patent Office on the 17th March 1876.
.
TO ALL TO WHOM THESE PRESENTS SHALL: COME, we, SAMUEL
TURNER, the younger, JOHN TURNER, and ROBERT TURNER, all of
Rochdale, in the County of Lancaster, send greeting.
WHEREAS Her-most Excellent-Majesty Queen Victoria, by Her 25
Letters Patent, bearing date the Eighteenth day of September, 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 Samuel Turner, John Turner,
and-Robert-Turner, Her special license that we, the said Samuel Turner, 30
John Turner, and Robert Turner, our executors, administrators, and
assigns, or such others as we, the said Samuel Turner, John Turner,
and Robert Turner, our executors, administrators, and assigns, should at

page_text: 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 Inven-
5 tion for "IMPROVED MEANS FOR SECURING THE JOINTS OF STEAM AND WATER
PIPES, AND FOR OTHER SIMILAR PURPOSES," upon the condition (amongst
others) that we, the said Samuel Turner, John Turner, and Robert
Turner, our executors or administrators, by an instrument” in writing
under our, or one of our, or their, or one of their hands and seals,
) should particularly describe and ascertain the nature of the said Inven-
tion, 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 immediately after the date of the said Letters Patent.
.
NOW KNOW YE, that I, the said Samuel Turner, the younger (on
behalf of myself and the said John Turner and Robert Turner), do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascer-
tained in and by the following statement and accompanying Drawings :—
This Invention relates to the flat rings or washers of india-rubber or
other suitable elastic material or composition, such as are used for
placing between the flanges of pipes to form a steam, water, or air-tight
joint, and the object of the Invention is to strengthen such rings or
washers and increase their power of resistance without detracting from
the flexibility or elastic of their surfaces which form the joint.

The Invention consists principally in combining with such flat india-
rubber or other elastic rings or washers strengthening rings of metal of
a trough-like section applied (by preference) to their outside circum-
ference, but the metal rings may, if thought desirable, be applied to
their inner circumference or edge, or even to both edges thereof.
The metal strengthening rings form as it were a rim or ring with two
narrow flanges projecting from its inner edges, if the ring is to be
applied to the outside of the washer, or from its outer edges if the ring
is to be applied to the inside of the washer, and the edge of the india-
rubber washer is to be embraced and held firm between these two
flanges. The india-rubber or other elastic material is thus prevented
from expanding laterally by undue pressure, at the same time that
owing to the narrowness of the flanges the greater part of the india-

page_text: •
rubber or other elastic surfece is left exposed so as to form the steam,
water, or air tight joint in as efficient a manner as heretofore.
In the annexed Drawing Fig. 1 is a face view, and Fig. 2, a section
of an india-rubber washer with our Invention applied thereto, a, a,
being the india-rubber, and b, b, the metal strengthening ring, which in
this case is shown as applied to the outer circumference of the india-
rubber ring or washer.
:
Fig. 3, is a face view, and Fig. 4, a section of a similar washer with
the strengthening ring b, b,shown as applied to the interior of the
washer a, a.
As before stated (if preferred) the strengthening rings may be applied
to both the inner and outer edges.
Having now described the nature and object of our said Invention,
we wish it to be understood that we claim, the combination with flat
india-rubber or other elastic rings or washers of metallic strengthening
rings of a trough-like section, substantially in the manner and for the
purposes herein-before more particularly set forth and described.
In witness whereof, I, the said Samuel Turner, the younger (on
behalf of myself and the said John Turner and Robert Turner),
have hereunto set my hand and seal, this Fifteenth day of
March in the year of our Lord, One thousand eight hundred and
seventy-six.:
