I JOSEPH SHELDON of Stocksbridge near Sheffield in the County of York
"IMPROVEMENTS
Engineer do hereby declare the nature of my invention for
IN THE MANUFACTURE OF POLISHED AND ANNEALED WIRE OR SHEETS OF IRON
OR STEEL PARTLY APPLICABLE TO ANNEALING OTHER ARTICLES OF IRON OR STEEL
to be as follows:-
"
At the present time in the manufacture of fine wire or sheets of iron or steel the
metal is repeatedly drawn or rolled down cold to reduce it to the dimensions
required and is repeatedly annealed to allow of its being so rolled or drawn.
In order also that the metal may roll or draw properly it is required to be clean
and bright.
.
With the ordinary process now employed for annealing iron or steel wire or
sheet the surface of the metal gets scaled and discolored each time that it is
annealed and bas to be cleaned before it is again rolled or drawn.
The cleaning is effected by scouring the surface of the metal with spirits of salts
or other acid which unless used with great care is very injurious to the motal
According to my invention in order to anneal the iron or steel wire or sheets in
between the successive rolling or drawing operations I place them into a cast iron
pot which is then filled up with cast iron turnings so as to fill in all the spaces
between the articles and between them and the sides of the pot so as as far as
practicable to make the contents of the pot into a solid mass containing but little
air. The pot is then covered over with a close fitting cover and luted over to
make an air tight joint.-Afterwards the pot is slowly heated in a furnace and
subsequently allowed to cool. Preferably I heat the pots by placing them within
heated rotating cylinders or pots as described in the specification of a former
Patent granted to Samuel Fox No 5234 in the year 1883 but they might be hentod
in other ways.
By annealing the articles in the above manner they will when taken out still
retain their original polished appearance.
The above process of annealing is applicable not only for annealing iron or steel
in the form of plates or wires but also for annealing all kinds of forgings or
castings of these metals.

Wire or Sheets of Iron or Steel, partly Applicable to Annealing
other Articles of Iron or Steel.
I JOSEPH SHELDON of Stocksbridge near Sheffield in the County of York
Engineer do hereby declare the nature of my invention for "IMPROVEMENTS IN
THE MANUFACTURE OF POLISHED AND ANNEALED WIRE OR SHEETS OF IRON OR
STEEL PARTLY APPLICABLE TO ANNEALING OTHER ARTICLES OF IRON, OR. STEEL,”
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:-
At the present time in the manufacture of fine wire br sheets of iron or steel'
the metal is repeatedly drawn or rolled down cold to reduce it to the dimensions
required and is repeatedly annealed to allow of its being so rolled or drawn.
in order also that the metal may roll or draw properly it is required to be cloan
and bright.
With the ordinary process now employed for annealing iron or steel wire or
sheets the surface of the inctal gets scaled and discolored each time that it is
annealed and has to be cleaned before it is again rolled or drawn.
The cleaning is effected by scouring the surface of the metal with spirits of salts
or other acid which unless used with great care is very injurious to the metal.
By my invention I do away with the necessity for these ropeated scourings of
the surface of the metal.
The annealing of the iron or steel wire or sheet in between the successive rolling
or drawing operations I effect in the following mannor.
I place the wire or sheet into a cast iron pot which is, then filled up with cast
iron turnings so as to fill in all the spaces between the articlos and between them
and the sides of the pot so da far as practicable to make the contents of the pot
into a solid mass containing but littlo air The pot is then covered over with a
close fitting cover and luted over to make an air tight joint.
Afterwards the pot is slowly heated in a furnace and subsequently allowed to
cool Preferably I beat the pots by placing them within heated rotating cylinders
or pots as described in the Specification of a former Patent granted to Samuel Fox
No 5234 in the year 1883 but thoy might be heated in other ways.
By annealing the articles in the above way between or before the successive
rolling or drawing operations they will when taken out of the annealing pots still
retain their original polishod appearance and it is unnecessary to subject, the
surface of the metal to the action of acid as heretoforo or to finally burnish or
polish it as is now requisite.
The above process of annealing is applicable not only for annealing iron or steel
in the form of plates or wires but also for annealing all kinds of forgings or
castings of these metals,
In the drawings hereunto annexed I have shown various views of an annealing
pot such as I prefer to employ for annealing rolls of wire or thin sheet iron or
steel in the above manner.

page_text: Figure 1 is a vertical section Figure 2.a plan view and Figure 3 a horizontal
section of the pot.
:
In these figures A is the pot, B its lid, C are the coils of wire or narrow strips
of sheet metal-they rest one above another upon a flange D at the bottom of a
tubular centre piece E. F. F. aro bars placed across this centre piece by which it
and the coils C can be raised and moved from place to place. G. G. is a filling of
cast iron turnings or borings with which the coils are entirely surrounded.
H. H. are trunnions on the exterior of the pot A-they serve for lifting the pot
and also allow of the pot when suspended by them being readily turned over and
emptied of its contents.
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. The process of manufacture of polished and annealed wire or sheets of iron or
steel consisting in alternately cold rolling or drawing the sheet or wire and
annealing by heating it in closed pots filled with cast iron borings or turnings
substantially as described.
2. Annealing articles of iron or steel by heating them in pots filled in with
borings or turnings of cast iron and subsequently allowing them to cool sub-
stantially as described..
