PROVISIONAL SPECIFICATION left by the said Julius Whitehead at
the Office of the Commissioners of Patents, with his Petition, on
the 21st September 1874.
I, JULIUS WHITEHEAD, of Over Darwen, in the County of Lancaster,
Fire-clay Works Manager, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY TO BE EMPLOYED IN THE MANU-
FACTURE OF EARTHENWARE PIPES, OR SANITARY TUBES, BRICKS, AND TILES," to be
as follows:
The object of this Invention, so far as relates to the machinery to be
employed in the manufacture of earthenware pipes or tubes, is the con-

page_text: struction of apparatus in such manner as to afford considerably increased
facility for feeding, controlling, and operating the machine.
Secondly. To improved machinery or apparatus for "tempering" the
clay, and for preventing stone or other hard substance passing to the
dies of tube, brick, or tile-making machines.
The machinery employed in the manufacture of earthenware pipes or
sanitary tubes I construct as follows:-A steam cylinder and plunger
and feed box are arranged in the horizontal position. Connected with
and in continuation of the feed box is a curved feed pipe or tube leading
to the die which is in or about a vertical position; so that the feed box
and the die or dies are at about right angles to each other. A platform
placed between the feed box and the die enables the operator to supply
the feed box as required, as well as to control the action of the steam
cylinders plunger, and remove the pipes as formed.
:
The clay required for the manufacture of such pipes or sanitary tubes,
or for the making of bricks or tiles, is by the action of a plunger
forced through or along a "tempering box" or tube, within which
a series of rows of knives or blades arranged obliquely are placed, each
of such knives or blades of the several rows are placed so as to be “one
within the other" and at opposite angles, the clay on being forced
through is thoroughly cut and tempered.

page_text: Such being the nature and object of this my said Invention, I will
now proceed to describe the same in detail, and in order that the
Invention may be clearly understood, I have annexed two Sheets of
Drawings, and have marked the same with figures and letters of
reference, the same letter referring to the same parts in the several 5
views or Figures.

page_text: described operated and operating in the new and improved manner as
above fully set forth.
In witness whereof, I, the said Julius Whitehead, have hereunto
set my hand and seal, this Eighteenth day of March, in the
year of our Lord One thousand eight hundred and seventy-
five

Julius Whitehead in the
