Sealed the 20th November 1874, and dated the 22nd May 1874.
PROVISIONAL SPECIFICATION left by the said Charles Pearson, Joseph
Dean, and Thomas Cowling at the Office of the Commissioners of
Patents, with their Petition, on the 22nd May 1874.
WC, CHARLES PEARSON, JOSEPH DEAN, and THOMAS COWLING, of
Morton, near Bingley, in the County of York, Silk Spinners, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN SCREW
GILL BOXES FOR PREPARING SILK, WOOL, OR OTHER FIBROUS SUBSTANCES FOR
"COMBING," to be as follows:-
This Invention relates to well-known machinery called "screw gill.

page_text: boxes," used for preparing wool or other fibrous substances for combing,
and the improvements consist,-
Firstly. In the application of a porcupine roller working in a concave
shell or bed for presenting and holding the silk, wool, or other fibres to
the "gills" or "fallers" to be received thereby, and operated upon so
as to commence the lashing action as soon as possible after the fibre
leaves the nip. This shell is so formed and applied as that the fibre may
be presented close to the first gill or faller, the porcupine and the said
shell forming a ripping or holding apparatus at the point of delivery to
the gills, and thereby we are enabled to operate on short woolls or fibres;
or the said roller and shell may be placed at any suitable distance from
the gills for operating on long wools or fibres.
Secondly. In applying an intersecting feeder or an additional set of
gills to the back or feeding end of the ordinary set of gills to work in
conjunction therewith, each set of screws being of different pitch or
speed of rotation thereof, so as to obtain a draught on the fibre in passing
through the said gills; and by variation of relative speed of said two
sets of gills we obtain any desirable amount of draught on the fibre.
This improvement is especially adapted for preparing short wools,
silks, waste of all kinds, cotton, short flax, or other fibrous substances of
short staple.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 25
filed by the said Charles Pearson, Joseph Dean, and Thomas
Cowling in the Great Seal Patent Office on the 21st November
1874.

This Invention relates to well-known machinery called screw "gill
boxes," used for preparing wool or other fibrous substances for combing,
and the improvements consist,—
Firstly. In the application of a porcupine roller working in a concave
shell or bed for presenting and holding the silk, wool, or other fibres to
the "gills" or "fallers" to be received thereby, and operated upon so
as to commence the lashing action as soon as possible after the fibre
leaves the nip. This shell is so formed and applied as that the fibre may
be presented close to the first gill or faller, the porcupine and the said
shell forming a nipping or holding apparatus at the point of delivory to

page_text: the point where the fibre is transferred from one set to the other the
gills F may be curved in the form shewn in Fig. 2.
In witness whereof, I, the said Charles Pearson, for and on behalf
