IMPROVEMENTS IN THE
SPINDLES OF SPINNING
PROVISIONAL SPECIFICATION left by the said Charles Herbert Openshaw
at the Office of the Commissioners of Patents on the 30th July 1881.
CHARLES HERBERT OPENSHAW, of Bury, in the County of Lancaster, Cotton
Spinner. "IMPROVEMENTS IN THE METHOD OF AND MEANS FOR MOUNTING THE
SPINDLES OF SPINNING MACHINERY."
My Invention relates more particularly to the spindles of throstles. I mount each
spindle to revolve within a tubular pillar or long collar which is formed with or
carries the upper bearing for the spindle, and is formed or provided at the lower
end with an enlargement or chamber of a bulb or bridge form, or of a suitable
form to contain the wharve. An opening or openings is or are provided for the
passage of the driving band, and for the obtainment of access to the wharve.
The lower end of the pillar is bolted, screwed, or secured to the rail, and I prefer
that the upper end shall extend nearly to the boss of the flyer. The upper bearing
is preferably a short distance from the top of the pillar, so that a space to act as an
oil cup is provided. The footstep is formed or fitted on or in a plug or part
which is fitted or screwed in or into a hole in the rail, or is otherwise bolted or
secured to the underside of the rail, the said hole being sufficiently large to permit
the wharve to pass through it, so that when the footstep piece is removed the
spindle can be withdrawn from the pillar or long collar. The rail may be made
solid, or be thickened or formed with a pap at the point where the said hole is
formed. The arrangement enables me to use a shorter and lighter spindle, and to
run it at a high speed.

the said Charles Herbert Openshaw in the Great Seal Patent Office on the
30th January 1882.
CHARLES HERBERT OPENSHAW, of Bury, in the County of Lancaster, Cotton
Spinner. "IMPROVEMENTS IN THE METHOD OF AND MEANS FOR MOUNTING THE
SPINDLES OF SPINNING MACHINERY."
My Invention relates more particularly to the spindles of throstles. I mount
each spindle to revolve within a tubular pillar or long collar which is formed with
or carries the upper bearing for the spindle, and is formed or provided at the
lower end with an enlargement or chamber of a bulb, bridge, or other suitable
form to contain the wharve. An opening or openings is or are provided for the
passage of the driving band and for the obtainment of access to the wharve.
The enlargement at the lower end of the pillar is bolted, screwed, or otherwise
secured to the rail, and I prefer that the upper end of the long collar shall extend
nearly to the boss of the flyer. The footstep is formed or fitted on or in a plug or
part which is fitted or screwed in or into a hole in the footstep rail, or in the base
of the pillar, or is otherwise bolted or secured to the rail, the said hole being
sufficiently large to permit the wharve to pass through it, so that when the
footstep piece is removed the spindle can be withdrawn from the pillar or long
collar.
"
And in order that the manner in which I carry my Invention into effect may be
fully understood I have attached hereto a Sheet of Drawings made to a scale of
about half the linear dimensions of the examples selected for illustration, the said
Drawings being marked with letters of reference. Referring to the said Drawings,
Fig. 1 represents a sectional elevation of my improved mounting for a throstle
spindle, and Fig. 2 represents a cross sectional plan of the same.
In the said Figs.,
or in Fig. 1, a is the tubular pillar or long collar, b is the ordinary lifting rail, and
c is the fixed or footstep rail. The pillar a in the example is cast or formed in one
piece with two legs or supports d, d, which form as it were a bridge, within which
-is-a-chainber-which-is-open-on-two-sides, and-which contains-the-wharve-or-
whorl" c. The legs d, d, are formed with feet f, f, whereby the pillar a is firmly
screwed or bolted to the rail c. The form of the lower part d of the pillar may be
greatly varied so long as it serves to connect the said pillar firmly to or into the
rail, and at the same time permits of easy access to the wharve for the purpose of
putting on the band or for other purposes. By way of example I will state that
the part & may be made of a cylindrical or bulb form so that it can be turned,
outside openings for access to the wharve being provided, or one leg, or. three or
more legs may take the place of the two, but I do not consider such a form to be
advantageous. If preferred the tubular part a may be screwed or fixed to the
part d, which would be formed as a separate piece. The pillar a is bored to clear
the spindle g of the flyer and to receive the two bearings, one h near the upper end
of the pillar, and the other i at the junction thereof with the legs. I prefer that
the upper bearing may be a short distance from the top of the spindle in order
that a space to act as an oil cup may be provided. I prefer to employ German
silver bushes for the said bearings, but any suitable materials may be adapted for
the purpose. A channel is turned at j, and oil ducts or an oil duct lead or leads
from this channel to the bearing. The footstep is let into a plug which is
screwed into a tapped hole which is formed in the rail. This hole is made a little
larger in diameter than the wharve, so that when the said plug is unscrewed and
removed the spindle can be withdrawn downwards through the said hole without
disturbing the fastenings of the pillar. If preferred the said plug may be drilled

page_text: to form the footstep, and in place of being screwed it may be a plain cylinder
secured by means of a flange, as indicated in Fig. 5, or otherwise secured, or it
may be partly a plain cylinder and partly screwed, the rail may be made solid or
be thickened or formed with a pap at the point where the hole to receive the said
plug is formed. If not considered to be necessary the bearing i may be dispensed
with, but I prefer to retain it. The arrangement enables me to use a shorter and
lighter spindle, and to run it at a higher speed. Figs. 3 and 4 illustrate a
modification wherein the part d is formed with a boss which unites the lower ends
of the two legs and enters the hole in the rail, which hole is bored a little larger
than in the case of the example first described. The said boss is bored and tapped
to receive the footstep plug, which may be modified in form as herein before
mentioned. This modification enables me more readily to obtain a true adjustment
of the bearings, as I can bore the hole to receive the said plug whilst the pillar is
fixed or adjusted for the boring of the tubular collar, so that it is only necessary to
ensure that the footstep bearing shall be exactly in the centre of the plug, or the
necessary accuracy may be secured by boring the footstep at the same time or with
the same adjustment as the upper bearings. A modification in the method of
securing the pillar to the rail may be effected by extending the said boss beyond
the lower side of the rail sufficiently to receive a nut, or the said boss may be
secured within the hole by means of a set screw or of set screws.
Having now fully set forth and indicated the nature of the said Invention, and
the manner in which I carry and may carry the same into practical effect, I would
have it to be understood in conclusion that I claim,-
First. The pillars or long collars serving as mountings for throstle spindles
secured to the bottom or footstep rail, substantially as set forth and indicated
herein before and in and by the accompanying Drawings.
Secondly. The long collar for throstle spindles formed or provided with legs or
with an enlargement at the lower end to provide space for the wharve and for
access thereto, and secured to the footstep rail, substantially as set forth and
indicated.
-
Thirdly. The footstep plug fitting into a hole in the rail, through which hole the
spindle and wharve can. be passed in connection with a long collar, substantially as
and for the purpose set forth and indicated.
And Lastly. The tube or long collar a fitted with a bearing or with bearings for
a spindle, the legs d for securing to the footstep rail, and the plug secured in a
hole in the said rail or in the base of the said long collar, substantially as and for
the purpose or purposes set forth and indicated.
In witness whereof, I, the said Charles Herbert Openshaw, have hereunto
set my hand and seal, this Twenty-seventh day of January, in the year
of our Lord One thousand eight hundred and eighty-two.
