PROVISIONAL SPECIFICATION left by the said Thomas Tunstill at the
Office of the -Commissioners of Patents, with his Petition, on the 9th
August 1867.
I THOMAS TUNSTILL, of Burnley, in the County, of Lancaster, Cotton
Spinner and Manufacturer, do hereby declare the nature of the said
Javention for "IMPROVED MEANS AND APPARATUS FOR PREPARING SIZE FOR WARPS
OR OTHER PURPOSES" to be-as-follows:-
This Invention consists in the employment-of-a-boiling vessel or pipe placed
by preference in or near a vertical position, having an inlet at bottom and an
outlet at top. A steam pipe is introduced through the top which extends to

mixing vessel is employed, and an ordinary force pump is connected thereto.
and to the inlet of the boiling vessel. The pump draws the size from the
mixing vessel and forces it into and gradually up the boiling vessel or pipe
through the outlet into another vessel for supply, or it may be conducted from
the outlet direct to the sizing machine. Steam at high pressure is forced
through the perforations of the central pipe, which mixes and combines with
the size, whereby it becomes thoroughly boiled in its passage therethrough.
A tap or valve is applied to the outlet for closing the same and regulating the
quantity and time. of discharge, and a pipe with a weighted valve is also con-
nected to the inlet pipe for returning the surplus quantity forced by the pump
back into the mixing vessel.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Tunstill in the Great Seal Patent Office on the 19th
February 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS

NOW KNOW YE, that I, the said Thomas Tunstill, do hereby declare the
nature of my said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
thereof and accompanying Sheet of Drawings (that is to say):-
This Invention consists in the employment of a boiling vessel or pipe placed
by preference in or near a vertical position, having an inlet at bottom and an
outlet at top. A steam pipe is introduced through the top which extends to
near the bottom of the vessel and having perforations therein; the usual
mixing vessel is employed, and an ordinary force pump is connected thereto
and to the inlet of the boiling vessel. The pump draws the size from the
mixing vessel and forces it into and gradually up the boiling vessel or pipe
through the outlet into another vessel for supply, or it may be conducted from
the outlet direct to the sizing machine. Steam at high pressure is forced
through the perforations of the central pipe which mixes and combines with
the size, whereby it becomes thoroughly boiled in its passage therethrough.
A tap or valve is applied to the outlet for closing the same and regulating the
quantity and time of discharge, and a pipe with a weighted valve is also con-
nected to the inlet pipe for returning the surplus quantity forced by the pump
back into the mixing vessel.

and boiling it to the finest state of liquid consistency hitherto not attained in
the preparation of sizing for warps or similar purposes.
In witness whereof, I, the said Thomas Tunstill, have hereunto set my
hand and seal, this Eighteenth day of February, One thousand eight
hundred and sixty-eight.
