CHARLES KNOWLES, Millwright and Machinist, Wharf Iron Works, Mytholmroyd
in the County of York. I do hereby declare the nature of my invention for AN
IMPROVED SELF-LUBRICATING REVOLVING YARN ROLLER AND BEARINGS FOR
LOOMS to be as follows:-
-
The revolving rollers in use at present have a neck turned on them about 1″ dia
and 2 inches long, and these necks work in half circular bearings; this causes a
great amount of friction on them so that the roller will not revolve when the warp
passes over, thus stretching the warp so much that thin and thick places are woven
in the cloth and also causing the yarn to break.
To obviate this I turn a neck about 14 inches from the end of roller and this
1 inches I turn into a ball. The bearings I make in the form of a box with an
arm to fix to loom and may be made of iron brass or other suitable metal. This
box may be either open or closed at the top, but an opening is left at one side
about two thirds of the depth or other suitable distance over which the neck in the
roller is laid while the ball alone rests on the bottom and (when working) against
one side of the box thus reducing the friction to a minimum If the box be made
of iron it may have brass bearings or linings fitted into the bottom and the side
where the ball presses against This box can be filled with oil in which the ball
will revolve thus making it self-lubricating and needing no attention for months.
The bearing being in a place the workpeople are constantly passing the oil when
enclosed in a box is much less liable to get rubbed onto the cloth than in the
exposed bearing of the old style.

I, CHARLES KNOWLES of Wharf Iron Works Mytholmroyd in the County of
York Millwright & General Machinist do hereby declare the nature of my
invention for AN IMPROVED SELF-LUBRICATING REVOLVING YARN ROLLER AND
BEARINGS and in what manner the same is to be performed, to be particularly..
described and ascertained in and by the following statement:-
The revolving Rollers in use at present have a neck or pivot about 1 inch in
-diameter and 2 inches long and work in half circular bearings this causes a great
amount of friction in the neck so that the roller will-not-revolve regularly when
the warp passes over it thus causing thick and thin places to be woven in the
cloth and also causing a great number of threads composing the warp to break.
To obviate this I make the fixed bearing in the form of a box (A) with an arm
to fix to loom these can either be made of Brass Iron Steel or other suitable
material and the Box bearing (A) can be made with flat concave or convex sides
and bottom and either open or closed at top but an opening is left on one side
about two thirds the depth or other suitable distance to admit the revolving Roller
which I make as follows I turn out a recess or neck, say for example 7/8 of an inch
wide at a suitable distance from the end but preferably 13/4 inches the portion then
left at the end I turn somewhat in the shape of a Ball (C) and then I place the
recess (B) in the opening in the side of the Box bearing (A) then only the centre
of the Ball (B) will rest on the bottom of the bearing (A) and (when in motion)
against one side of the box thus reducing the friction to a minimum If the box (A)
be made of Iron it may have brass steel or any other suitable linings placed inside
to further reduce the friction. Also the box (A) can be filled with oil in which the
ball (C) will revolve thus making it Self-lubricating and needing no attention for
weeks The bearings being in a place where the work people are constantly passing
in the old exposed bearing the oil often gets rubbed of onto the warp and cloth
thereby doing considerable damage but the oil being enclosed in the box (A) in my
method this is entirely avoided.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The mode of mounting the yarn roller substantially as hereinbefore described.
In Witness whereof I the said Charles Knowles have to this my said
Specification set my hand this fourteenth day of January one thousand
eight hundred and eighty five.
