IMPROVEMENTS IN YARN POLISHING MACHINERY
Year: 1879

page_text: LETTERS PATENT to Harvey Heywood, Manufacturer, and John Holland,
Manager, both of Tonge, near Manchester, in the County of Lancaster, for the
Invention of "IMPROVEMENTS IN YARN POLISHING MACHINERY."
Sealed the 27th December 1879, and dated the 12th July 1879.
PROVISIONAL SPECIFICATION left by the said Harvey Heywood and John
Holland at the Office of the Commissioners of Patents on the 12th July
1879.
HARVEY HEYWOOD, Manufacturer, and JOHN HOLLAND, Manager, both of Tonge,
near Manchester, in the County of Lancaster. "IMPROVEMENTS IN YARN POLISHING
MACHINERY."
The improvements relate to yarn polishing machinery, and consist of improved
rollers for carrying and stretching the yarn during the time the same is being
operated upon by the polishing brushes, and also to the construction of bearings or
carriers for such rollers.
In yarn polishing machines as at present used the rollers for carrying the yarn
and for causing the same to travel in a strained condition before the revolving
brushes are constructed for the most part with a shaft running through the centre
of each roller, which shaft at each end runs in a suitable bush or bearing requiring
lubrication, and as these rollers require to have the hanks of yarn passed over their
ends, both at putting on and taking off, it is obvious that there is danger of dirt
and damage to the yarn from probable contact with the oil or other lubricant upon
the shaft. Furthermore, the method of construction adopted and bereinbefore
alluded to renders the rollers, especially where long ones are required, of great
weight, which adds much to the labour of taking them in and out of the machine
for the purpose of changing the yarn.
To remedy these defects, and to effect our improvements we form the rollers of
metal tubes, by preference of drawn brass, with antifriction rings or pulleys of
malleable iron or other suitable metal at each end. At one end of one or both
of such tubular rollers is fitted to, or made to form part of the antifriction rings or

page_text: pulleys already alluded to, a sunken toothed wheel or wheels, which, when the
roller is in position, takes into a corresponding toothed wheel attached to or forming
part of an antifriction_pulley, upon which the antifriction ring or pulley of the
roller rests. Other antifriction pulleys, with or without flanges, are employed to
keep the tubular rollers in the required. position, or it may be that slides or
guides. may be used for this latter purpose, by which means we dispense with
the necessity of having any portion of the yarn carrying roller or tube lubricated,
thereby rendering the same less liable to soil or damage the yarn under opera-
tion, and by much diminishing the weight we add materially to the comfort of
the workpeople employed. In case greater strength in the rollers is required we
employ one or more diaphragms, which may be composed of metal or wood, as found
most convenient.

HARVEY HEYWOOD, Manufacturer, and JOHм HOLLAND, Manager, both of Tonge,
near Manchester, in the County of Lancaster. " IMPROVEMENTS IN YARN POLISHING
MACHINERY."
The improvements relate to yarn polishing machinery, and consists of improved
rollers for carrying and stretching the yarn during the time the same is being
operated upon by the polishing brushes, and also to the construction of bearings
or carriers for such rollers. In yarn polishing machines as at present used the
rollers for carrying the yarn, and for causing the same to travel in a strained
condition before the revolving brushes are constructed for the most part with a
shaft running through the centre of each roller, which shaft, at each end, runs in
a suitable bush or bearing requiring lubrication, and as these rollers require to
have the hanks of yarn passed over their ends, both at putting on and taking off,
it is obvious that there is danger of dirt and damage to the yarn from probable
contact with the oil or other lubricant upon the shaft. Furthermore, the method.
of construction adopted, and herein before alluded to, renders the rollers, especially
where long ones are required, of great weight, which adds much to the labour
of taking them in and out of the machine for the purpose of changing the yarn.
To remedy these defects, and to effect our improvements, we form the rollers
of metal tubes, by preference of drawn brass, with antifriction rings or pulleys
of malleable iron or other suitable metal at each end. At one end of one or
both of such tubular rollers is fitted to or made to form part of the antifriction
rings or pulleys already alluded to a sunken toothed wheel or wheels, which, when
the roller is in position, takes into a corresponding toothed wheel attached to or
forming part of an antifriction pulley, upon which the antifriction ring or pulley
of the roller rests. Other antifriction pulleys, with or without flanges, are employed
to keep the tubular rollers in the required position, or it may be that slides or
guides may be used for this latter purpose, by which means we dispense with the
necessity of having any portion of the yarn carrying roller or tube lubricated,
thereby rendering the same less liable to soil or damage the yarn under operation,
and by much diminishing the weight we add materially to the comfort of the work-
people employed. In case greater strength in the rollers is required we employ
one or more diaphragms, which may be composed of metal or wood, as found most
convenient, or it may be that a modification of the same may be adopted, by so
forming the tubular rollers that they shall be capable of running upon studs taking
into sockets in the rollers in lieu of the antifriction pulleys.
But that the arrangements may be better understood we will, by the aid of tho
accompanying Drawings, proceed further to describe means emploved by us
Fig. 1 shows an end elevation; and Fig. 2 a front view of apparatus arranged
according to our Invention; and Figs. 3 and 4 show sectional views of the
modification thereof.
In each of these Figures the same letters indicate corresponding parts wherever
they occur.
a, a, is part of the main framing of the machine; b, b, are the rollers or tubes }
and b', 6', are the antifriction rings or pulleys with toothed gearing 62 attached by
any suitable means. These rings or pulleys rest upon the corresponding pulleys c', c¹,
attached to the toothed gearing c², c², and to the shaft c³, c³, which has motion
imparted to it in the usual manner. The tubes or rollers b, b, are kept in position by

page_text: the supplemental antifriction pulleys d, d, which may or may not be provided with
flanges, or in lieu of these supplemental pulleys fixed guides may be used; e, e, shows
a portion-of-the-revolving-brush; and ff the yarn upon the rollers. The usual
or any other suitable motions may be employed for drawing the rollers forward,
taking them out of gear or stopping and starting the same, either in conjunction
with or separately from the rest part of the machine.
Having now described our improvements and ineans we adopt in carrying the
same into effect, we would have it understood that we do not confine ourselves to
the exact details shown and described; as variations may be made without departing.
from the peculiar character of our Invention, but what we do claim is,―
-The application-to yarn polishing machinery of tubular rollers constructed with
or without diaphragms, and with antifriction rings or pulleys affixed to or forming
part of the ends thereof, and resting upon other antifriction pulleys, or carried
by meads of studs taking into sockets and geared to a suitable driving apparatus for
the purpose herein before stated, and substantially as shown and described.
In witness whereof, I, the said Harvey Heywood, have hereunto set my hand
and seal, this Sixteenth day of December, in the year of our Lord One
thousand eight hundred and seventy nine.
Witness,
