ANNEALING APPARATUS,
Lysaght's Invention of Improvements in means or apparatus for Annealing Iron
Sheets generally.
The Invention has for its object improvements in means of annealing Iron Sheets
and other articles by passing them through a furnace with a continuous and regular
movement by which means the Iron Sheets or articles are more equally and perfectly
annealed.
For this purpose we employ at one end of the furnace a pair of rolls with suitable
hearings fitted to plates or frames of convenient form to allow the sheets to pass
through the inlet of the furnace and on to a travelling endless chain which receiving
the sheets or articles carries them on and are finally passed out through the outlet at
the other end of the furnace.
The said apparatus is fitted with suitable arrangements to allow for adjustment as
may be required and by means of pullies and belts the whole of the apparatus has one
constant and regular motion.
In order that our invention may be more clearly understood and readily carried into
effect we will proceed aided by the accompanying drawings more fully to describe the
same.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a side elevation of the said Annealing Apparatus showing the relative
positions of the working parts constructed according to our invention.
Fig. 2 is a vertical section or view taken on the line OO showing the various parts
of the whole apparatus.

page_text: Fig. 3 is a plan showing the internal arrangement of the said apparatus.
A A is a pair of rolls fitted with suitable bearings with a pair of pinions fixed on one
end of the rolls and a pulley fixed on the other end of one roll to drive the said rolls
which convey the iron sheets or articles through the inlet B B of the furnace and
deliver them on to an endless chain CC which convey the sheets or articles on through
the furnace and are finally delivered out through the outlet D D.
The endless
chains CC have a continuous motion and are driven by a set of chain sheaves or
pullies E E fixed on to the shafts FF tlie said shafts are fitted with suitable bearings,
pulley and arrangements which give the required and uniform speed to the whole
apparatus.
Having thus described the nature of our invention and the manner in which we
carry the same into effect we would have it understood that we do not confine ourselves
to the precise details herein.shewn and described, but what we do claim is the novel
combination and arrangement of means or apparatus for annealing Iron Sheets or
articles generally substantially as herein shown and described.

page_text: We JOHN LYSAGHT and JOHN LYSAGHT Limited 36.Gracechurch Street London E.C..
also at Bristol & Wolverhampton manufacturers of Galvanized Iron.etc etc. 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 :-
The invention has for its object improvements in means of annealing Iron Sheets and
other articles by passing them through a furnace with a continuous and regular
movement by which means the Iron sheets or articles are more equally and perfectly
annealed.
For this purpose we employ at one end of the furnace a pair of Rolls with suitable
bearings fitted to plates or frames of convenient form to allow the sheets to pass
through the inlet of the furnace and on to travelling endless chains which receiving
the sheets or articles carries them on and are finally passed out through another pair
of Rolls at the outlet at the other end of the furnace.
The said apparatus is fitted with suitable arrangements to allow for adjustment as
may be required and by means of pullies and belts the whole of the said apparatus has
one constant and regular motion.
In order that our Invention may be more clearly understood and readily carried into
effect we will proceed aided by the accompanying drawings more fully to describe the
same.
DESCRIPTION OF THE DRAWINGS.
Fig. 1. is a longitudinal section of the said annealing apparatus showing the relative
positions of the working parts constructed according to our Invention.
Fig. 2. is a sectional plan showing the arrangements of the said apparatus.
Fig. 3. is a vertical section or view taken along the line O, O, showing the various
parts of the whole apparatus.
The said annealing apparatus and furnace is constructed as follows:-
The walls and roof are made of fire brick strengthened at the sides by means of cast
iron stancheons G, G, tied at the top by means of Wrot Iron tie rods H, HL. J, J, is
the firegrate, and the fire is stoked through the door. K, K, the heat generated here
is forced through the long upper chamber by the draught and finally escapes at the
outlet or flue L, L. A, A, are pairs of rolls fitted with suitable bearings and with a
pair of pinions fixed on one end of the rolls and a pulley on the other end of one roll
to drive the said rolls C, C, are endless chains having a continuous motion and are
driven by a set of chain sheaves or pullies E, E, fixed on the shafts F F, these said

page_text: shafts are fitted with suitable bearings, pulleys and arrangements which give the
required motion and uniform speed to the whole apparatus. M, M are cast iron
grooved chairs to guide and support the endless chains C, C.
The necessary motion having been given to the said endless chains by means of the
gearing above described the Iron or Steel sheets or articles to be annealed are drawn
between the rollers A, A, and conveyed through the opening B, B on to the endless
chains C, C, and are finally delivered by them out through the opening D, D. The
Iron-plate N, N, being arranged to guide the said articles between the rollers A, A, at
the outlet end of the said Furnace.
Having thus described the nature of our Invention and the manner in which we
carry the same into effect we would have it understood that we do not confine ourselves
to the precise details herein shown and described but 'what we do claim is,
The novel combinations and arrangements of means or apparatus for annealing Iron
or Steel sheets or articles generally, substantially as herein shown and described.
