IMPROVEMENTS IN THE CONSTRUCTION OF APPARATUS USED FOR GASSING YARN
Year: 1878

page_text: LETTERS PATENT to Benjamin Brown, of Bury, in the County of Lancaster,
for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF APPARATUS
USED FOR GASSING YARN."
Sealed the 24th January 1879, and dated the 13th August 1878.
PROVISIONAL SPECIFICATION left by the said Benjamin Brown at the
Office of the Commissioners of Patents on the 13th August 1878.
BENJAMIN BROWN, of Bury, in the County of Lancaster.
THE CONSTRUCTION OF APPARATUS USED FOR GASSING YARN."
"IMPROVEMENTS IN
This Invention relates to the gassing machines used for swinging off the loose
fibres from yarn, and more particularly to the arrangement for mounting and dis-
mounting the grooved rollers or drums round which the yarn passes whilst being
gassed or singed.
The studs upon which these grooved rollers are mounted have hitherto been made
to project beyond the boss of the rollers, and the latter have been secured thereon
by means of a pin passing through a hole in the end of the stud. These pins are
troublesome to remove and replace, and frequently become lost or misplaced.
I provide the roller with a long boss having a rim or flange at one end. This end
passes between the pin and a fixed cylindrical cover, which protects the stud and
prevents the yarn from touching the same and becoming oiled if it should slip off
the grooved roller. This cover is provided with a notch in the upper side at such
a distance from the end that the flange on the boss of the grooved roller just passes
beyond it, and the cover is provided with a curved catch (hinged thereto), which
falls through the notch and holds against the flange so as to prevent the grooved
roller from being drawn endwise off the stud till the catch is raised.
When it is desired to remove the grooved roller all that is necessary is to turn
the catch over on its hinge.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Benjamin Brown in the Great Seal Patent Office on the 12th
February 1879.

Such being the nature and object of my said Invention I will now proceed to
describe in detail the manner in which the same is to be or may be performed or
carried into practical effect, and in order that the same may be clearly understood
I have annexed hereunto a Sheet of Drawings illustrative thereof, and have
marked the same with figures and letters of reference corresponding with those
in the following explanation thereof.
The studs upon which these grooved rollers are mounted have hitherto been
made to project beyond the boss of the rollers, and the latter have been secured
thereon by means of a pin passing through a hole in the end of the stud. These
pins are troublesome to remove and replace, and frequently become lost or mis-
placed.
My improved construction of grooved roller and stud is shown in plan view
complete at Fig. 1, Fig. 2 being an end view thereof with the roller removed;
Fig. 3 is a plan view with the roller detached; Figs. 4 and 5 are horizontal and
vertical sections of the same.
I provide the roller a, a, with a long boss b, b, having a rim or flange c, c, at one
end. This end passes between the pin d, d, and a fixed cylindrical cover e, e, which
protects the stud or pin d, d, and prevents the yarn from touching the same and
becoming oiled if it should slip off the grooved roller a, a, see Fig. 4. This cover e, e,
is provided with a notch f, f, in the upper side, see Figs. 3 and 5, at such a distance
from the end that the flange c on the boss b, b, of the grooved roller a, a, just
passes beyond it, and the cover e, e, is provided with a curved catch g, g, (hinged
thereto) which falls through this notch f, f, and holds against the flange c, c, (see
Figs. 1 and 2) so as to prevent the grooved roller a, a, from being drawn endwise
off the stud d, d, till the catch g, g, is raised.
When it is desired to remove the grooved roller a, a, all that is necessary is to
turn the catch g, g, over on its hinge, as shown at Figs. 3 and 5; h, h, is the thumb
nut by means of which the pin d, d, is fixed to the rail of the gassing machine.
Having now described the nature and object of my said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, I wish it to be understood that I claim as my Invention the construction of
apparatus for the above purpose as herein-before described, and illustrated by the
Drawings annexed, and more especially I claim the flange c, c, at the end of the
boss of the grooved roller, the fixed cylindrical cover e, e, and the curved catch g, g,
working through a notch in the same.
In witness whereof, I, the said Benjamin Brown, have hereunto set my hand
and seal, this Eleventh day of February, in the year of our Lord One
thousand eight hundred and seventy-nine.
