IMPROVEMENTS IN WRINGING AND MANGLING MACHINES
Year: 1876

page_text: LETTERS PATENT to Louis Sleeman Webb, of 52, Linthorpe Road, Middles-
borough-on-Tees, for the Invention of "IMPROVEMENTS IN WRINGING AND
MANGLING MACHINES."
Sealed the 26th May 1877, and dated the 6th December 1876.
PROVISIONAL SPECIFICATION left by the said Louis Sleeman Webb at the
Office of the Commissioners of Patents on the 6th December 1876.
LOUIS SLEEMAN WEBB, of 52, Linthorpe Road, Middlesborough-on-Tees. "IM-
PROVEMENTS IN WRINGING AND MANGLING MACHINES."
I pass an iron rod under the dies under the bottom roller, and carry the rod up to
and fix on one end of levers; the other end works under the top spring, and so
suspend the rollers so that the bottom roller is not resting on a solid foundation,
thus making both rollers do equal work. I get the same action by means of an
extra spring placed under the bottom dies. I pass the spindles of driving wheels
through the said dies, and so tie the wheels and prevent them lifting out of gear.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Louis Sleeman Webb in the Great Seal Patent Office on the 29th
May 1877.
LOUIS SLEEMAN WEBB, of Middlesbrough, in the County of York, Machinist.
"THE SELF-ADJUSTMENT OF THE GEAR WHEELS AND THE PRESERVATION OF THE
ROLLERS IN WRINGING AND MANGLING MACHINES."
The Invention relates to the construction of improved apparatus in wringing and
mangling machines, and the Invention has for its objects the self-adjustment of the
gear wheels and the preservation of the rollers (which by the present system splits
and gets broken when high pressure is applied).
To attain the desired even pressure I suspend the rollers A, which are made of
round sections clamped together by pressure, by passing rods B under the bottom
dies C, and bringing them up to one end of levers D, the other end of said levers
resting against the spring, which also presses on the top dies E, thus preventing the
[Price 4dl

page_text: bottom roller from lying on a solid foundation, and so making both open equally
from the centre, and act alike to the spring. Any strain or uneven work that the
machines are subject to through the carelessness of the persons using them by
allowing one roller to drop suddenly on to the other is received by the spring F in
place of the bottom roller, as in the old style. I tie the driving wheels G, which
are made of maleble cast metal, together by passing the shafts on which the wheels
work through the die E, and so prevent them from lifting out of gear, thus obviate
the breaking of wheels which occurs in the present system of gearing.
In place of star wheels on the other end of shafts I key on two wheels H, less in
diameter than the rollers, and in each of these I run a small one I, the two smaller
ones running into each other. The pins on which the smaller wheels revolve slide in
slots J in the side of the machine. The four are linked together to prevent them
lifting out of gear.
Having now described the nature and objects of my said Invention, together with
the manner in which the same is to be or may be carried into practical effect, I
would remark in conclusion that I claim as my Invention the above described
improved apparatus for wringing and mangling machines, combining the principle
of the self-adjustment of the gear wheels and the preservation of the rollers.
In witness whereof, I, the said Louis Sleeman Webb, have hereunto set my
hand and seal, this Nineteenth day of May, in the year of our Lord One
thousand eight hundred and seventy-seven.
LOUIS SLEEMAN WEBB. (L.S.)
