Complete Specification Left, 13th July, 1899-Accepted, 16th Sept., 1899
Improvements in and connected with Composition Covered Rollers
Employed in Textile Spinning and for like Uses.
I, ANDREW BENNIE, of The Thornton Woollen Mill Company, in the City of
St. Petersburg, in the Empire of Russia, Spinner, do hereby declare the nature
of this invention to be as follows:-
-
This invention has reference to an improved manufacture of the class of rollers
referred to in the Specification of a former Patent granted to me and dated the
14th day of February last No. 3686, but in which I specified as the main solid
ingredient leather dust, but I prefer to dispense with the side flanges to the
rollers therein described.
I have since found that for some uses it is more convenient to employ a
different composition which has advantages in practical use, by reason of the
materials being more readily procurable in quantity and otherwise.
According to my improved manufacture I employ the following materials, in
approximately the following quantitive proportions, although I do not confine
myself strictly thereto, but only give the same as an instance of a composition
which my experiments have shewn me to be a useful one: that is to say,
Sawdust (finely reduced or ground, and preferably in
the proportion of one half of Beech sawdust to
one half of pine or like sawdust (well admixed)
-
39 parts
It will possibly be found convenient for use in spinning, drawing &c cotton,
silk and other fibres than wool or worsted to make a slight modification in the
ingredients to suit the requirements of the particular materials treated, but this
will be readily ascertained by a little trial.

page_text: I have for simplicity described the quantity of water as being added in bulk
but this may be modified adding the same in instalments as prescribed in my said
former specification if found more convenient.

Improvements in and connected with Composition Covered Rollers
Employed in Textile Spinning and for like Uses.
I, ANDREW BENNIE, of The Thornton Woollen Mill Company, in the City of
St. Petersburg, in the Empire of Russia, Spinner, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement:-
This invention has reference to an improved manufacture of the class of rollers
referred to in the Specification of a former Patent granted to me and dated the
14th day of February 1898 No. 3686 but in which I specified as the main solid
ingredient leather dust, but I prefer to dispense with the side plates or protective
discs to the rollers therein described.
I have since found that for some uses it is more convenient to employ a
different composition which has advantages in practical use by reason of the
materials being more readily procurable in quantity and otherwise.
According to my improved manufacture I employ the following materials, in
approximately the following quantitive proportions although I do not confine
myself strictly thereto, but only give the same as an instance of a composition
which my experiments have shewn me to be a useful one: that is to say,
Sawdust (finely reduced or ground, and preferably in
the proportion of one half of Beech saw-dust to
-one half of Pine or like sawdust well admixed)

drawing rollers.
I have also found it to be advantageous to mould the composition in the form
of rings upon temporary metal or like discs or foundations instead of moulding
the composition on the wooden roller bosses on which they are to be actually used
thus: I take an iron disc a facsimile of an actual wood boss and mould the com-
position round it, precisely as I would do if applying directly on to a wood boss.
I then slip the rings off the temporary supports or discs when moulded and place
them in a cool place to dry. When dry I glue the composition rings with common
glue or the like to the boss.
-
The wood bosses are first turned down to fit the bore of the composition rings.
I have found that when the composition was moulded directly around the wood
bosses that it became necessary to take the bosses off the spindles.

page_text: die plate may be formed with (say for instance) 18 perforated circular holes or
annular spaces such as that one which is indicated by the opening a but as the
main feature of this apparatus is already in substance described and claimed in
the said prior specification I make no claim to its construction here.
The iron twisting roller to be covered with the improved composition is passed
on the spindle c of the die or support d and a washer e the same diameter as the
roller is placed on the top of the roller b and a nut f fastened to the spindle.
(This washer prevents any composition from passing into the hollow centre
of the roller). I then place the rollers into the openings a and pour the com-
position into the annular spaces between the roller band the walls of the open-
ings a.
Some of the advantages of the use of these twisting rollers are that:-
rollers.
They cost less than leather covers being made from the refuse or waste spinning
The composition covers when cut up by wear can be stripped off the rollers
and returned to the boiler to be used over and over again.
Having no joints they do not open or slip as leather covers sometimes do. By
these means a saving of a large per centage of yarn which is at present lost
through or owing to the thread lapping round the leather covered rollers is
effected.
It will possibly be found convenient for use in spinning, drawing etc., cotton,
silk and other fibres than wool or worsted to make a slight modification in the
respective proportions of the ingredients to suit the requirements of the par-
ticular materials treated but this will be readily ascertained by a little experi-
mental test or trial for the particular material or quality of material.
I have for simplicity described the quantity of water as being added in bulk
but this may be modified adding the same in instalments as prescribed in my
said former specification if found more convenient.
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 improved compositions of materials and process or method of applying
the same in the formation of composition covered rollers for textile spinning
and like uses as set forth.
