PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Loom Picking Bands and
Apparatus used therein.
I, THOMAS CLARKE, of the firm of Thomas Clarke & Son, of Mersey Works,
Astley Street, Stockport, in the County of Lancaster, Curriers, do hereby declare
the nature of this invention to be as follows:-
This invention relates to improvements in the manufacture of picking bands and
apparatus used therein and has for its object to render such bands splashless and
more durable.
In order to give the same the required pliability and strength, heretofore it has
been customary to curry the leather with a mixture of tallow and sod or tallow
and cod oil applied in a cold and pasty state, which mixture will not set sufficiently
in the leather and thus causes the picking band when in operation to splash the
fabric woven, which is a great evil as it damages the same considerably.
In order to remedy this defect I curry the leather by suspending it a desired
length of time, in tallow or other soluble fatty matter, desolved by means of heat.
The apparatus I use to impregnate the leather with tallow or other soluble
fatty matter, consists of a chamber of suitable size and material, subdivided in a
number of smaller chambers. Each alternate one of the said small chambers,
which I term treating chambers, is charged with consistent tallow or other fatty
matter and adapted to receive the leather to be impregnated thereby, whilst the
intervenient chambers or spaces serve for the reception of the heating medium.
As such I may employ water heated by steam or hot air pipes, or steam or hot
air pipes only, or gas jets and the like as may be found most convenient and will
ensure a uniform heating of the treating chambers and its contents.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Loom Picking Bands and
Apparatus used therein.
I, THOMAS CLARKE, of the firm of Thomas Clarke & Son, of Mersey Works,
Astley Street, Stockport, in the County of Lancaster, Curriers, do hereby declare
the nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to improvements in the manufacture of loom picking
bands and apparatus used therein and has for its object to render such bands
splashless and more durable.
In order to give the same the required pliability and strength, heretofore it has
been customary to curry the leather with a mixture of tallow and sod or tallow
and cod oil applied in a cold and pasty state, which mixture will not set sufficiently
in the leather and thus cause the picking band when in operation to splash the
fabric woven, which is a great evil as it damages the same considerably.
In order to remedy this defect I curry the leather by suspending it a desired
length of time, in tallow or other liquefiable fatty matter, desolved by means of
heat.
And in order that my invention may be more fully understood I have caused to

page_text: be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a cross section, Fig. 2 a longitudinal section and Fig. 3 a plan of
Fig. 1, of an apparatus for treating leather for picking bands according to my
invention.
Fig. 4 is a detached view showing a modification thereof.
In carrying out my improvements and referring to Figs. 1, 2 & 3, the apparatus
I use to impregnate the leather a with tallow or other liquefiable fatty matter,
consists of a chamber a¹ of suitable size and material, say wood, suitably secured.
together liquid tight and subdivided in a number of smaller chambers b & b.
Each alternate chamber which I term treating_chambers, is charged with con-
sistent tallow or other fatty matter and adapted to receive the leather a to be
impregnated thereby, whilst the intervenient chambers or spaces 6 serve for the
reception of the heating medium. As such, I may employ water heated by steam
or hot air pipes c or steam or hot air pipes only, see Fig. 4, or gas jets and the
like as may be found most convenient and will ensure a uniform heating of the
treating chambers and its contents.
The treating chambers b, which I preferably form of metal, are supported in the
chamber a¹ by means of rails e, a short space f being left below the same in which
is employed the heating medium or pipe c.
The leather a to be treated I suspend, in the treating chambers 6 in sheets, by
means of hooks g placed onto the sides of the chamber a', or otherwise as may
be found most convenient, and the latter if deemed necessary may be covered as
shown in dotted lines.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is-
.
"In the manufacture of loom picking bands."
1st. The method of currying the leather, by suspending it in tallow or other
liquefiable fatty matter disolved by means of heat, substantially as and for the
purpose set forth.
2nd. An apparatus for currying leather, consisting of a chamber a' containing
treating and heating chambers 6 & 1, substantially as and for the purpose set
forth.
