PROVISIONAL SPECIFICATION.
An Improvement relating to Plates for Pressing Cattle Food Cakes.
I, HEREERT EDWIN CHATTOCк, of Penner Mills, Redcliff Street, Bristol,
engineer, do hereby declare the nature of this invention to be as follows:-
This invention which relates to press plates employed, as is well-understood,
for pressing cakes of cattle food, consists in providing the said plates on both
faces with a covering plate of sheet zinc. The covering plates of sheet zinc are
pressed or otherwise made to conform to the configuration of the faces of the plates
to which they are applied and to which they are soldered or otherwise suitably
attached.
By the use of press plates thus faced with sheet zinc, adhesion under pressure
of the cakes of cattle food to the plates is obviated, a smooth and glossy finish is
imparted to the cakes, and the surfaces by which these objects are attained are
more durable than those hitherto adopted for the said purpose.

I, HERBERT EDWIN CHATTOCK, of Penner Mills, Redcliff Street, Bristol,
engineer, 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 plates employed in pressing cakes of cattle-food. In
order to prevent the cakes from adhering to the plates, the practice has hitherto
been to galvanize the pressing faces of the plates which are commonly made of
cast malleable iron, but may be of steel or wrought iron.
Now this invention consists in covering each pressing face of the ungalvanized
plates with a sheet of zinc or tin which is separately made from the ungalvanized
plate and is soldered or otherwise attached thereto; the ungalvanized body plate
being sandwiched between the two plates of sheet zinc or tin. The facing plates
of zinc or tin are sufficiently thin as to yield under pressure in a hydraulic press
and thus to be pressed to conform to the configuration of any pattern or device
or devices borne upon the ungalvanized body and intended to be printed upon the
cakes of cattle-food. The plates of sheet zinc or iron are pressed to the said
configuration prior to attachment to the ungalvanized body plate. After having

page_text: been pressed to make the required pattern and device or devices, the facing plates
of sheet zinc or tin are fixed to the body plate by soldering around the edges, or
by like means.
In the accompanying sheet of drawings, Fig. 1 represents, in longitudinal
section, an example of a cattle-food pressing plate made in accordance with this
invention. Fig. 2 is a plan of half of one face. The face is ridged and grooved
on both faces, as is commonly the case. The body a of the plate is, as is usual,
made of malleable cast iron, wrought iron, or steel. On the upper and under
faces are separate plates b of sheet zinc or tin. The plates b, which have been
previously pressed on the respective faces of the plate a in a hydraulic press, are
secured to the said plate a by soldering or other like means.
Obviously, in cases where the plates are plain, that is to say, smooth, no
previous pressing is required.
Cattle-food pressing plates made in accordance with this invention are much
more durable than those hitherto usually used, and, by their use, the smoothness
and finish imparted to the cakes of cattle-food is enhanced.
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:
Plates for pressing cattle-food cakes, consisting of a core or body of wrought
iron, cast, malleable iron, steel or other suitable metal, faced at top and bottom
with covering sheets of sheet zinc or tin fixed to the said core or body, substantially
as hereinbefore described.
