IMPROVEMENTS IN THE MANUFACTURE OF LINT, AND IN MACHINERY EMPLOYED THEREIN
Year: 1864

page_text: PROVISIONAL SPECIFICATION left by David Shaw Brown at the Office
of the Commissioners of Patents, with his Petition, on the 23rd
August 1864.
I, DAVID SHAW BROWN, of Runcorn, in the County of Chester, Manager,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE MANUFACTURE OF LINT, AND IN MACHINERY EMPLOYED THEREIN," to be as
follows:-
Hitherto it has been the practice to make lint at two operations, that is to
say, the fabric is first woven and then the fabric is subjected to the action of
a knife to scrape up the fluffy surface thereon. Now the object of my present
Invention is both to weave the fabric and form the fluffy surface at one
operation.
I take any loom or machine for weaving, but by preference an ordinary
calico loom, and apply thereto a knife or knives and a shaft or harness
working a false or imitation warp consisting of fine wires for the purpose of
assisting or lending strength to the warp proper of the fabric being woven, or
the false warp may consist of fine knives for severing the weft between the
threads of the warp; the ends of weft so severed are thrown to one surface of
the fabric, and are teazed to bring up a fine fluffy surface. Some shoots of
weft are left undivided to hold the fabric together.

page_text: The manner in which I carry my Invention into effect will be fully under-
stood by the annexed Drawings, and the following description thereof.
warp
Fig. 1 is a perspective view of a portion of a loom; b, b, is the batten; a, a
knife working in grooved guides e, e, and having its edge resting on the
warp g, g; f is the lint which passes off between a pair of rollers, by prefer-
ence fluted, one of which is marked h, and the other removed to show more
upon the
clearly the working parts of the loom. The knife a rests
until
it reaches to near the point o, where the weft is driven home by the sleys.
The forward sweep of the batten then causes the projection a¹ to strike the
projection or boss d', whereby the shunt c, c, is driven in the direction of the
projection, and forced under the knife a, which is raised from the warp;
this motion will be better understood by Figs. 2 and 3, which are respectively
a front elevation of the knife shunt c, c, and a back elevation of the knife a.
When the shunt is driven from a¹ to a, as just stated, by the projection a¹
coming against the boss d', the parts of the shunt pass under the pro-
jections or journals a¹ of the knife, force them up to c¹; and thereby raise the
knife. When the batten sweeps back, the projection a strikes against a
wheel d", hereafter described; the shunt is thereby driven back, and the
knife released by the projections or journals a¹ slipping down the inclined part
of the shunt to b. The shunt c is supported by a rod n and by the batten at
the points w, w; d2 is a wheel with a large indentation 2, and working in, a
slot 1 in the frame of the loom; this wheel is caused to revolve in order that
at stated intervals the indentation 2 may be inside to meet some alternate
back sweeps of the batten whereby the knife is not released, but will ride on
the shunt during the next forward and return sweeps of the batten. The
wheel d may be caused to revolve by bevil gearing on a shaft or spindle
carrying other gearing in connection with the driving shaft; k, l, are shafts
or harness for the warp proper; ³ is a shaft or harness for working a false
or imitation warp of fine wire or other suitable material at intervals with the
shafts or harness k, k³, so that the wire warp may be uppermost when the
knife remains on the shunt, as last described. The wire warp is interwoven
with the lint for a few inches, and is for the purpose of easing the strain upon
the warp proper which becomes weakened by the
lint afterwards slips away from the wire warp.

Instead of a wire warp, fine knives for severing the weft between the
threads of the warp may be used, as before mentioned, or the false or imitation
warp may, if desired, be entirely dispensed with.
