Year: 1878

page_text: LETTERS PATENT to Patrick Kelly, of Sutton Mills, Cross Hills, in the County
of York, Overlooker, for the Invention of "IMPROVEMENTS IN THE METHOD
OF AND APPARATUS FOR THE PREPARATION OF LONG AND SHORT WOOL."
Sealed the 14th March 1879, and dated the 21st September 1878.
PROVISIONAL SPECIFICATION left by the said Patrick Kelly at the Office
of the Commissioners of Patents on the 21st September 1878.
_PATRICK KELLY, of Sutton Mills, Cross Hills, in the County of York, Overlooker.
"IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR THE PREPARATION OF
LONG AND SHORT WOOL."
This Invention relates to certain improvements in the preparation of long and
short wools or other fibrous materials, and consists of an arrangement by which I
am enabled to apply two sets of gills or fallers to the preparing machine; the screws
working the front and back sets of gills or fallers are in the same line, thus each
set of fallers are the same length and are worked independently of each other by
separate sets of screws; the back set of screws and fallers can be driven in the
ordinary manner the same as a single gill preparing box, and the other or front set
of screws and fallers are driven by means of a shaft that is placed at the under side
or below the two sets of fallers which work on the same plain. Motion to this
shaft is obtained from the shaft driving the back screws and fallers by means of a
train of change wheel gearing, and at or near the other end of the said shaft I fix
another train of change wheel gearing, that is in connection with the screw shaft
of the front set of screws and fallers; thus by these means I am enabled to regulate
the relative speed of rate of travel between the front and back set of fallers,
according to the requirements of the different lengths of staple the machine is
preparing.
Between the front and back set of fallers and near to each end of the same I fix
a thin guard, in order that the fallers may work almost close to each other and rise
and fall without one set coming coming into contact with the other set.

"IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR THE PREPARATION OF
LONG AND SHORT WOOL."
This Invention relates to certain improvements in the preparation of long and
short wools or other fibrous materials, and consists of an arrangement by which I
am enabled to apply two sets of gills or fallers to the preparing machine; the
screws working the front and back sets of gills or fallers are in the same line, thus
each set of fallers are the same length and are worked independently of each other
by separate sets of screws. The back set of screws and fallers can be driven in the
ordinary manner the same as a single gill preparing box, and the other or front set
of screws and 'fallers are driven by means of a shaft or shafts that is or are placed
at the under side or below the two sets of fallers which work on the same plain.
Motion to the last-named shaft or shafts is obtained from the shaft driving the
back screws and fallers by means of a train of change wheel gearing at the back
end and a train of change wheel gearing at the front end of the said shaft or shafts,
this last-named gearing is in connection with the screw shafts of the front set of
screws and fallers, thus by these means I am enabled to regulate the relative speed
or rate of travel between the front and back set of fallers according to the require-
ments of the different lengths of staple the machine is preparing.
In order that the front and back sets of fallers may rise and fall in close
proximity with each other I fix a thin guard between the front and back sets near
to the screws at each end of the fallers, by which means the back set of gills or
fallers can fall to the bottom screws and the front set rise without one set coming
into contact with the other set.
Such being the nature and object of this my Invention I will now proceed to
describe the same in detail, and in order that the same may be fully understood I
have hereunto annexed one Sheet of Drawings to be hereafter referred to, and have
marked the same with letters of reference.
Figure 1 represents the longitudinal section of such portions of a preparing box
as are required to ellucidate my Invention; Figure 2 is a plan of the same, shewing
the front and back screws in line with each other; Figure 3 is a detail of the stays
I employ for supporting the screws and fallers; and Figure 4 is a section of the
screws, shewing the method I adopt for keeping the axes of the front and back
screws lineable. In all the Figures similar letters represent similar parts.
The letter A represents the framework of the preparing box; B and B¹, the top
and bottom back screws which are driven in the same manner as an ordinary
single gill preparing box; C and C₁ are the top and bottom front screws which are
in the same axial line as the back screws; these front screws C and C' are driven
by the train of change wheel gearing D mounted at each side of the machine which
connects the bottom screw shafts B' to the additional shafts E, which are mounted
in suitable brackets F at the under side of the bottom screws B' and C¹. At the
front end of each of the additional shafts E I mount another set or train of change
gearing G, which connects the shafts E to the front screws C, C; these wheels D
and G can be so changed or regulated that the relative speed or travel of the front
and back screws and fallers can be adjusted to suit the requirements of the varied
or different lengths of staple the machine is required to manipulate.
It will be easily understood by practical wool combers and others conversant
with the preparation of wool that I am enabled to so regulate the relative speed
of the front and back sets of fallers by means of the change gearing before
described, that I can prepare either long or short stapled wool or other fibrous sub-
stances that may be required to be operated upon.

page_text: In order to simplify the Drawings I have only shewn a portion of the fallers,
the front set of fallers are indicated by the letter H and the back set by J; between
the front and back sets near to each end of the same I secure two thin guards K, K,
for the purpose of conducting or guiding both the front and back sets of fallers in
the travel from the top to the bottom sets of screws or "vice versa."
The screws and fallers are supported by the brackets L, which are bored such a
diameter that the screws will freely revolve in the same and keep the axis of the
screws lineable; on these brackets L are saddles M, which project towards the
centre of the machine and carry the fallers whilst travelling the length of the
screws.
Having thus described my said Invention, and the manner in which the same
may be carried into effect, I would have it understood that I do not confine myself
to the precise details as to the means I employ to actuate the front set of screws, as
motion to the same can be obtained from other parts of the machine; but what I
believe to be novel and original and claim as the Invention secured to me by the
herein in part recited Letters Patent is,--
The arrangement of separate screws for driving the front and back sets of gills
or fallers, the axes of such screws being in line with other, substantially for the
purposes herein-before described and illustrated by the accompanying Drawings.
The arrangement of a thin guard between the front and back fallers at each
side of the same near to the screws, substantially for the purpose herein-before
described.
The arrangement and combination of the several parts of the machine, sub-
stantially for the purpose herein-before described and illustrated by the accom-
panying Drawings.
In witness whereof, I, the said Patrick Kelly, have hereunto set my hand
and seal, this Eighteenth day of March, in the year of our Lord One
thousand eight hundred and seventy-nine.
PATRICK KELLY. (L.S.)
