PROVISIONAL SPECIFICATION.
An Improvement relating to Annealing Tin and Terne Plates.
I, WILLIAM BRAZELL, of Berkeley Street, Plasmarl, Landore, in the County
of Glamorgan, Roll Turner, do hereby declare the nature of this invention to he
as follows:—
This invention relates to the process of annealing tin and terne plates and has
for its object to expedite the said process and thereby to economise fuel.
Hitherto, in the process of annealing tin and terne plates, the practice has been
to pile all the sheets contained in one annealing box in one pack in the box, the
sheets thus forming a dense mass which takes a considerable amount of time in
becoming heated to the requisite degree for annealing.
Now this invention consists in dividing such a pack into a series of smaller packs
by interposing at suitable distances apart stands, each stand being composed of a
pair of flat iron plates maintained at a short distance vertically apart by studs or
blocks intervening between them. By the use of such stands interposed at intervals,
as aforesaid, the heat plays more freely and uniformly through and about the
pile of plates which are consequently annealed with greater expedition and with
reduced consumption of fuel.

COMPLETE SPECIFICATION.
An Improvement relating to Annealing Tin and Terne Plates.
I, WILLIAM BRAZELL, of Berkeley Street, Plasmarl, Landore, in the County
of Glamorgan, Roll Turner, 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 the process of annealing tin and terne plates and has
for its object to expedite the said process and thus to economise time and fuel.
Hitherto, in the process of annealing tin and terne plates, the practice has been
to pile the sheets contained in one annealing vessel or "pot" in one pack in the
pot, the sheets thus forming a compact mass requiring a considerable amount of
time to become heated to the requisite degree for annealing.
Now this invention consists in dividing the charge for one annealing pot into
two or more separate packs which are piled upon trays or stands. The packs are
stacked one above the other in the pot. The trays, which may or may not be
perforated, are furnished on the underside with studs so that when the packs of
sheets are piled a space is left below each tray for free circulation of the heat.
The accompanying drawing represents in vertical section a box or "pot" a for
annealing tin and terne plates. The plates are arranged in accordance with this
invention, that is to say, in separate packs instead of, as heretofore, in one pack.
The packs are built up in trays c and piled as shown. The trays e have studs or
short legs e by virtue of which a space is obtained below each pack for better
distribution of heat which has free play through and about the packs. In the
drawing two packs only of plates are shown, but it is to be understood that the
plates may be divided into as many packs as may be desired consistent with the
dimensions of the annealing box or pot.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the-same is to be performed, I declare that what I
claim is
-
1. In the process of annealing tin, terne and like plates, a method of arranging
the plates in one annealing box or "pot in separate and distinct packs piled in
vertical series and having a space below each pack, substantially as hereinbefore
described.
2. In the process of annealing tin, terne and like plates, the use of trays such
as 6, with or without perforations, provided below with studs or legs such as e,
or their equivalent, said trays being placed in the annealing box or "pot" and
containing the plates, substantially as hereinbefore described with reference to
the accompanying drawing.
