IMPROVEMENTS IN MACHINERY FOR WEAVING, SIZING, DRESSING, AND DYEING
Year: 1863

page_text: LETTERS PATENT to Thomas Parkinson, of Blackburn, in the County of
Lancaster, Engineer, and Francis Taylor, of the same Place, Foreman,
for the Invention of "IMPROVEMENTS IN MACHINERY FOR WEAVING, SIZING,
DRESSING, AND DYEING."
Sealed the 2nd November 1863, and dated the 13th May 1863.
PROVISIONAL SPECIFICATION left by the said Thomas Parkinson and
Francis Taylor at the Office of the Commissioners of l'atents, with their
Petition, on the 13th May 1863.
We, THOMAS PARKINSON, of Blackburn, in the Gounty of Lancaster,
Engineer, and FRANCIS TAYLOR, of the same Place, Foreman, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR WEAVING,
SIZING, DRESSING, AND DYEING," to be as follows:-
Our improvements in machinery for weaving consist in applying an eccentric
roller to the back of the loom, over which the warp passes in going from the
warp beam to the healds; this roller is driven at the same speed as the crank
shaft; when tho shed is open from the passage of the shuttle the highest part
of the eccentric roller is towards the healds, thus relieving the warp from strain,
and when the reed is beating up tho weft the eccentric is in the opposite
direction, to tighten the warp. The requisite tension is given to the warp by
a band or chain passing around the warp beam, connected to a tightening screw
furnished with a regulating nut.

page_text: Our improvements in machinery for sizing, dressing, and dyeing consist in
agitating the liquids employed in such processes by means of a screw attached
to a vertical shaft, supported in the vessel containing the sizing, dressing, or
dyeing materials; this screw is turned round by steam or other power, and keeps
the contents of the vessel in agitation.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Parkinson and Francis Taylor in the Great Seal
Patent Office on the 12th November 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
PARKINSON, of Blackburn, in the County of Lancaster, Engineer, and FRANCIS
TAYLOR, of the same Place, Foreman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by IIer Letters
Patent, bearing date the Thirteenth day of May, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Thomas Parkinson and Francis Taylor, Her special licence that we, the said
Thomas Parkinson and Francis Taylor, our executors, administrators, and
assigns, or such others as we, the said Thomas Parkinson and Francis Taylor,
our executors, administrators, and assigns, should at any time agree with, and
no others, from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend, within
the United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY FOR WEAVING,
SIZING, DRESSING, AND DYEING," upon the condition (amongst others) that we,
the said Thomas Parkinson and Francis Taylor, our executors or administrators,
by an instrument in writing under our, or their, or one of our or their hands
and seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and causo
the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Thomas Parkinson and Francis
Taylor, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement (that is to say):
:-
Our Invention consists, first, in certain improvements in the letting-off
motion of looms for weaving; and secondly, in agitating liquids employed in

page_text: sizing, dressing, and dyeing, by means of a screw revolving in the vessel con-
taining the liquid.
And in order that our Invention may be fully understood and readily carried
into operation, we will proceed to describe the accompanying Sheet of Drawings,
reference being had to the figures and letters marked thereon.
Figure 1 is a side view, and Figure 2 a back view of part of a loom to which
our improvements are applied. a is the crank shaft; b, the warp beam ; and c,
an eccentric roller, over which the warp passes in going from the warp beam
to the healds; this roller is driven at the same speed as the crank shaft by
the wheels a' and c', shown by dotted lines; when the shed is open for the
passage of the shuttle, the highest part of the eccentric roller is towards the
healds, thus relieving the warp from strain, and when the reed is beating up
the weft the eccentric is in the opposite direction to tighten the warp. The
requisite tension is given to the warp by a band or chain d, passing around tho
warp beam, this band passes also over the guide pulley e, and the two ends of
the band are then united under the warp beam, and secured to the axle of the
ratchet wheel f, shewn in Figure 1; above this ratchet wheel is a retaining
catch for holding it when the wheel has been turned partly round to regulato
the tension of the band or chain, and consequently that of the warp. Or the
same object may be accomplished in the manner shewn in Figure 2, in which
view the band d, after passing around the warp beam b, and over the guide
pulley e, is connected to the tightening screw 9, which passes through tho
spring h, fixed to the back stay or other convenient part of the framing. The
screw 7 has a nut g', by which the tension of the warp can be regulated.
Our improvements in machinery for sizing, dressing, and dyeing are shown in
Figure 3, which is shewn partly in section; i is a screw attached to a vertical
shaft j, supported in the vessel k, containing the sizing, dressing, or dyeing
materials to be agitated; this screw is turned round by steam or other power
applied to the shaft, and the contents of the vessel are kept in agitation as
long as may be necessary; a clutch box is applied to the shaft I, to disconnect
the agitator when required. To the bush j, in which the shaft j revolves, is
fixed the arm, supporting an upright rod or scraper j³, for scraping tho
interior of the vessel and agitating the size or other material near the circum-
ference thereof. The shaft j and the bush are turned round in contrary
directions by the two pair of bevel wheels shewn in the Drawing.
Ilaving thus stated the nature of our Invention, and described the manner
of performing the same, we declare that we claim,―
First, the improvements in the letting-off motions of looms, and particularly
the tightening screw and regulating nut marked gaud g' in Figure 2.

page_text: And, secondly, we claim the application of a revolving screw for agitating
liquids employed in sizing, dressing, and dyeing.
In witness whereof, I, tho said Thomas Parkinson, have hereto set my
hand and seal, this Eleventh day of November, in the year of our Lord
One thousand eight hundred and sixty-three.
THOMAS PARKINSON. (L.s.)
