I, CONSTANT Ror of St. Maudé in the Department of Seine in the Republic of
France, Civil Engineer do hereby declare the nature of my invention for "IMPROVE-
MENTS IN ROLLING-MILLS to be as follows:-
22
My invention consists in new arrangements of automatic rollers in combination
with ovens for reheating and drawing metals. The rolling is performed by means of
10) two or more three high rollers, mounted one after the other, and between which
the metal bar to be rolled out, is passed rapidly; 2°) two or more two high rollers,
placed one above the other; 3°) one or more sets of three rollers, two of which are
horizontal, and one vertical; 4°) two or more ovens, placed on each side of the train,
in order that bars of large sections may pass through them and be reheated before
passing through the next rollers. The rollers are manipulated by means of gearing.
The automatic guidance for the bars, consists of a frame, in the front of the rollers;
said frame is on the other side of the rollers composed of two sections, the upper one
being provided with grooves, and a lower corresponding part.

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:-
My invention consists in new arrangements of automatic rolls in combination with
ovens for reheating and drawing metals.
The rolling and reheating is performed by means of
1°) two or more sets of three high rolls A, mounted one set in front of the other
and between which the metal to be rolled out, is passed rapidly.
2°) two or more sets of two high rolls B, placed one set above the other.
3°) one or more sets of three high rolls C.
4°) one or more sets of three rolls D, one or more of such rolls being horizontal
and one vertical.
5°) two or more sets of three high rolls E for rolling T iron.
6°) two or more sets of rolls F for rolling angles.
7°) two or more ovens G, G¹, placed on each side of the train of rolls, in order
that metals of large sections may pass through them in order to be reheated before
passing through the next rolls.
The accompanying drawings shew more fully the nature of the invention, in which
Figure 1 is a front view of a train of rolls; figure 2 is a plan of the same, shewing
also two ovens for reheating the metal; figure 3 is an end view of the rolls-the
housing A and placed between the two ovens G, G¹ for reheating the metal; figure 4
is an end view of the rolls in the housing B, with an automatic guide figure 5 is an
end view of the housing C; figure is an end view of the housing E; and figure 7
is a front view of rolls for rolling angles.
The rolls are manipulated by means of gearing, attached to one of their ends.
The guidance for the entering metal, consists of a frame i, placed in front of the
rolls. The said frame i is extended to the other side of the rolls, and consists there
of two sections, the upper one L being provided with grooves, and a lower corre-
sponding part n. o represents the metal, comming from the rolls and entering the
oven for being reheated; o¹ represents the metal returning to the rolls, and repre-
sents the metal passing from one housing to the other; S, S₁ represent some of the
various contours-or-sections, which can be given to the metal by means of this train
of rolls.

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 what I
claim is:
.
1°) The employment of ovens in combination with a train of rolls, substantially as
and for the purpose set forth.
2°) The combination with said ovens of alternately arranged sets of three & two
high rolls and three rolls, substantially as and for the purpose set forth.
3°) The employment of the guidance for the entering metals, substantially as and
for the purpose set forth.
