Improvements in Rolling-mills for Making Seamless Tubes.
A communication from WILLIAM HECKERT, of Findlay, in the County of
Hancock and State of Ohio, United States of America.
I, FREDERICK JOHN BROUGHAM, of No. 46 Lincolns Inn Fields, in the County
of London, Managing Clerk, do hereby declare the nature of this invention to be
as follows
This invention consists of certain improvements in rolling-mills for rolling
scamless hollow tubes, hereinafter more particularly described.
Efforts have frequently been made to roll seamless hollow tubing from a con-
tinuous hollow ingot by means of a mandrel passed through said ingot and
successive pairs of vertical and horizontal grooved rolls. Among the disadvantages
and difficulties incurred in the usual form of rolling-mill designed for this purpose
have been the great weight and cumbersomeness of the gearing, the roll-housings
and various parts of the main frame of bed plate, which have been difficult to
handle singly, and from the nature of their arrangement frequently required the
removal of a great many parts in order to get at that member of the combination
which needed repair or adjustment; and also the difficulty of properly centering
the mandrel within the hollow ingot and pipe when it is being rolled and of
bringing the reducing action of the rolls upon the bottom rather than upon the
sides of the grooves therein. In the use of the tapering mandrel, which has been
generally employed in machines of this kind, it has occurred that the pipe emerging
from one set of rolls passed on to a second set, in which it was to be still further
reduced upon a portion of the mandrel of less diameter than the internal diameter
of the tube itself. As a result the first reducing action of this second set of rolls
would frequently crush in the pipe at one side and force the mandrel to the other
side, whereupon, the metal closing around it, an imperfect pipe is formed, one side
being much thicker than the other, the internal and external circumferences being
eccentric instead of concentric one with another. To obviate these difficulties
above set out, and others not specifically enumerated, my correspondent has designed
the improved rolling-mill in which there is a main frame or bed-plate, upon which
the feed apparatus and the roll-housings are mounted. These roll housings
receive the several sets of rolls and are so arranged, that each set of rolls is
inclined at an angle of about 45° to the horizontal plane; but the consecutive sets
of rolls are at about right angles one to another. The rolls are mounted in suitable
bearings of the usual form placed in said housings, and the adjustment of said
rolls is brought about by the use of screws, mounted in caps upon the housings
according to the usual construction. The caps are held to the housings by bolts
the caps can be swung to one side and the rolls removed without necessitating the
removal of the caps. The housings have suitable feet by which they are bolted to
the bed-plate or frame.
j
The motive power is transmitted to each set of rolls through the main shaft.
Upon this shaft are mounted one or more bevel-wheels, which gear with corre-
sponding bevel-wheels upon shafts which are mounted in suitable bearings upon the
bed-plate, and are parallel to the length of said bed-plate. At proper points on
these shafts are mounted bevel-wheels, which gear with corresponding bevel-wheels
connected with the various sets of rolls, thereby giving a rotary movement thereto.
These bevel-wheels may of course be cast solid and keyed upon the shafts, or they
may preferably be made in two parts and fastened together by suitable bolts and
lugs in the well known way. With this latter arrangement, upon the breakage of
any gear-wheel by reason of too great a strain brought thereon, the fragments of

page_text: the gear-wheel may be removed and a new one put in its place without disturbing
other portions of the rolling mill and causing but a slight delay.
The apparatus for handling and feeding the ingot to the rolls consists of a
bracket in which the ingot may be dropped from an overhead travelling crane, and
which is vertically adjustable by means of the slots and bolts therein. The mandrel
is mounted on and practically a continuation of the piston rod, connected with the
piston operating in a compressed air or water cylinder. The piston and mandrel
are supported on a sliding cross-head and the motion of the piston is controlled by
compressed air, steam, or water, admitted alternately at either end of the cylinder
by means of valves in the valve chests, which said valves are connected by a valve
rod, which is oscillated by means of a lever. The lever is pivotted to the frame in
any suitable way, and terminates in a handle. It may be locked in any position by
means of a pin being dropped into suitable holes in a quadrant.
The perforated pipe is supplied with water from any suitable source, which is
controlled by a valve opened by a lever coming in contact with the cross-head at
the end of its backward stroke, thereby sprinkling the mandrel and cooling the
same.
On the forward motion of the mandrel into the ingot a spring closes the valve
and the flow of water so discharged is shut off. The water after cooling the
mandrel, as above described, drops into a drip-pan.
The mandrel is composed of a scries of sections, which are cach oval in shape,
and are so placed that the major axis of each section is just equal in length of
the minor axis of the preceding section and is parallel thereto, the difference
between the major axis and the minor axis of any one section gradually diminishing
until the mandrel terminates with its last and smallest section a true circle. In
other words, the ellipses of the successive sections diminish in eccentricity until
the limiting condition (the circle) is reached, it being understood that a circle may
be spoken of as an ellipse whose eccentricity is zero. This mandrel of course may
be made of one piece; but the preferable construction is to form it of a stem, upon
which the sections are slid and held in position by suitable headless set-screws. A
nut on the end of the mandrel also serves to hold all the sections in place upon the
stem.
The method of operation of the invention is the following: The heated ingot
being placed on the bracket, the lever is given a movement sufficient to open the
valve into the valve-chest and the inflowing air or steam forces the piston-rod and
mandrel forward, so that the mandrel passes into the ingot and into the passes of
the rolls. When the first section has entered the ingot, the internal diaincter of
said ingot being a little greater than the longer diameter or axis of the said
first section, it picks it up and forces it into the first pass of the rolls, the mandrel
stopping at this point and remaining at rest during the process of rolling which
follows. The rolls pull the ingot through them onto the second section of-the
mandrel thereby reducing it. From this set of rolls the pipe is forced onto the
next section. These rolls crush and reduce the pipe. In the same manner
the reduction on the remaining sections of the mandrel and within the remaining
sets of rolls goes through various shapes to the finished shape. The final section
of the mandrel is a true circle, as is also the pass in the last set of rolls, and the
product of the rolling-mill is a seamless tube of perfect circular cross-section and
equal thickness of walls throughout. By reversing the lever the steam or air
enters the other end of the cylinder and withdraws the mandrel. At the last
portion of the travel of the cross-head the lever is struck, which opens the valve
and permits water to enter through the pipe and fill the perforated pipe, from which
it drops upon the mandrel, cooling the same. When another ingot has been placed
in the bracket and the mandrel is given its forward motion, the spiral spring
operates the lever to close the valve and the flow of water is shut off.
The advantages of this improved rolling-mill are evident in its simplicity and
lightness, combined with strength. It is evident that with a breakdown at any
point, produced by any cause, the part damaged can be readily replaced without

page_text: disturbing other parts of the rolling-mill. It is also evident that as the pipe passes
off one section of the mandrel onto the next, it is positively held and centered by
the mandrel-section by virtue of the fact that the major axis of the elliptical pass
of the rolls at this point is equal to the minor axis of the ellipse to which the outer
surface of the pipe has been formed by the preceding set of rolls, while the inner
surface of the pipe is shaped to an ellipse whose minor axis is just equal to the
major axis of the said mandrel-section.
Moreover in view of the fact that the main reduction of the pipe by the rolls is
always in the direction of the major axis of the ellipse formed by the pipe's cross-
section, and that said major axis is always at right angles to the axis of the rolls
which is parallel to the minor axis the said reduction is nearly all done by the
bottom portion of the groove in each roll, and little or no pressure is brought upon
the sides of the grooves, so that there is no tendency to clog the rolls or tear the
stock by virtue of the different rates of speed at which the bottom of the groove
and the sides of the same are travelling, on account of their being nearer to or
farther from the center of the revolving roll. Again, whenever the action of any
set of rolls has worn down the end of the mandrel-section, which terminates in
the bight of said rolls, by the action of the pipe which is drawn down over the
end of each section to the lesser diameter of the next section, the sections of the
mandrel can be removed, put in a lathe, and have a portion of their ends turned
down to the shape of the next section and the entire mandrel moved forward on
its stem. These operations may be repeated until the mandrel is entirely worn out
and new sections then put on.
It will be noticed that throughout the operation the major axis of the tube is
presented to the minor axis of the mandrel-section, leaving a crescent-shaped
opening between the two, the action of the successive sets of rolls closing the tube
to the form of the mandrel-sections with little or no friction and wear on
the same.
While I have described the passes of the rolls and the sections of the mandrel
heretofore in general terms as being reduced copies one of the other, and while such
an arrangement would work, producing a finished pipe of the same thickness of
wall as the original ingot, but of much less diameter, in the preferred form of the
invention the passes of the rolls and the sections of mandrel corresponding thereto
are arranged so that the ellipse of the mandrel-section is of less eccentricity, more
nearly approaching the circle than the ellipse of the corresponding roll-pass. This
being the case, the wall of the pipe which corresponds to the side of the ellipse is
rolled thinner than that at the end, and as said side portion of each ellipse becomes
the end portion of the succeeding ellipse, it is evident that the thickness of wall
of the pipe, as well as its diameter, would be rapidly and evenly reduced, so that
the finished pipe can be of any thickness less than the thickness of the original
ingot. At the same time the essential point of the invention is not lost sight of,
to wit: that the dimension of each pass of the roll which is parallel to the axis of
that set of rolls shall be just equal to and not less than the dimension of the
preceding pass of the rolls which is at right angles to the axes of said preceding
set of rolls, so that there need be no work done by the sides of the grooves of the
rolls, but all such reducing work is brought upon the bottom of the grooves. It is
also evident that while the arrangement or alternating ellipses specially described
herein is the best arrangement of roll-passes and mandrel-sections for the rapid and
even reduction of the ingot, yet such reduction might be brought about by
alternating sections of different shapes and irregular form or of alternating elliptical
and circular shapes, so long as the differences in the pass of each roll and the cross
section of the mandrel above referred to are preserved, or so long as the arrangement
of succeeding parallel dimensions by which all work is taken from the sides of the
roll-grooves is preserved.

Improvements in Rolling-mills for Making Seamless Tubes.
A communication from WILLIAM HECKERT, of Findlay, in the County of
Hancock and State of Ohio, United States of America.
I, FREDERICK JOHN BROUGHAM of 46 Lincoln's Inn Fields in the County of
London, Managing Clerk, 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 consists of certain improvements in rolling mills for rolling
seamless hollow tubes. hereinafter to be more particularly described and claimed.
In the drawings,

the same.

the gearing for the rolls.

Figs. 8, 9, 10, 11, and 12 are detail cross-sections of different sections of the
mandrel and the ingot being rolled thereon; and
Fig. 13, is an end view of the mandrel.
Efforts have frequently been made to roll seamless hollow tubing from a continuous
hollow ingot by means of a mandrel passed through said ingot and successive pairs
of vertical and horizontal grooved rolls. Among the disadvantages and difficulties
incurred in the usual form of rolling-mill designed for this purpose have been the
great weight and cumbersomeness of the gearing, the roll-housings and various
parts of the main frame or bed-plate, which have been difficult to handle singly,
and from the nature of their arrangement frequently required the removal of a
great many parts in order to get at the member of the combination which needed
repair or adjustment; and also the difficulty of properly centering the mandrel
within the hollow ingot and pipe when it is being rolled and of bringing the reducing
action of the rolls upon the bottom rather than upon the sides of the grooves
therein. In the use of the tapering mandrel, which has been generally employed
in machines of this kind, it has occurred that the pipe emerging from one set of
rolls. passed on to a second set, in which it was to be still further reduced upon a
portion of the mandrel of less diameter than the internal diameter of the tube
itself. As a result the first reducing action of this second set of rolls would
frequently crush in the pipe at one side and force the mandrel to the other side,
whereupon the metal closing around it, an imperfect pipe is formed, one side being
much thicker than the other, the internal and external circumferences being
eccentric instead of concentric one with another. To obviate these difficulties
above set out, and others not specifically enumerated, my correspondent has designed
the improved rolling-mill illustrated, in which-
A represents the main frame or bed-plate, upon which the feed apparatus E and
the roll-housings B B B B, &c., are mounted. These roll-housings receive the
several sets of rolls R R', and are so arranged, as best shown in Figs. 2 and 3,
that each set of rolls is inclined at an angle of about forty-five degrees to the
horizontal plane; but the consecutive sets of rolls are about right angles one to
another. The rolls R R are mounted in suitable bearings of the usual form placed
in said housings, and the adjustment of said rolls is brought about by the use of
the screws F, mounted in caps G, upon the housings according to the usual con-
stinction. The caps G are held to the housings by bolts g g, and by forming one
end of the cap G, as shown in the dotted line figure, Fig. 4, the caps can be swung

page_text: to one side and the rolls removed without necessitating the removal of the caps.
The housings have suitable feet J J, &c., by which they are bolted to the bed-
plate or frame A.
The motive power is transmitted to each set of rolls through the main shaft W.
(shown in Fig. 2). Upon this shaft W are mounted one or more bevel wheels V VI,
which gear with corresponding bevel-wheels Z Z, upon the shafts S S!, which are
mounted in suitable bearings upon the bed-plate, and are parallel to the length of
said bed-plate. At proper points on these shafts S S' are mounted bevel-wheels,
which gear with corresponding bevel-wheels ¹¹, connected with the various sets
of rolls. thereby giving a rotary movement thereto. These bevel-wheels may of
course be cast solid and keyed upon the shafts, or they may preferably be made in
two parts and fastened together by suitable bolts and lugs in the well known way.
With this latter arrangement, upon the breakage of any gear wheel by reason of
too great a strain thereon, the fragments of the gear wheel may be removed and
a new one put in its place without disturbing other portions of the rolling-mill and
causing but a slight delay. The apparatus for handling and feeding the ingot to
the rolls consists of the bracket C, in which the ingot I may be dropped from an
overhead travelling crane, and which is vertically adjustable by means of the slots c
and bolts therein. The mandrel M is mounted on and practically a continuation
of the piston-rod H, connected with the piston operating in the compressed air or
water cylinder E. The piston and mandrel are supported on the sliding cross-
head N, and the motion of the piston is controlled by compressed air, steam or
water, admitted alternately at either end of the cylinder E by means of the valves
in the valve chests e e', which said valves are connected by the valve rod E', which
is oscillated by means of a lever P. The lever P is pivoted to the frame in any
suitable way, as at p', and terminates in a handle p. It may be locked in
any position by means of the pin being dropped into suitable holes in the
quadrant U.

The perforated pipe X is supplied with water through the pipe w from any
suitable source, which is controlled by the valve W, opened by the lever W

the mandrel as above described, drops into a drip-pan X¹.
The mandrel M is composed of a series of sections m, mm", &c., which are each
oval in shape and are so placed that the major axis of each section is just equal in
length of the minor axis of the proceeding section and is parallel thereto, the
difference between the major axis and the minor axis of any one section gradually
diminishing until the mandrel terminates with its last and smallest section a true
circle. In other words the ellipses of the successive sections diminish in eccentricity
until the limiting condition (the circle) is reached, it being understood that a circle
may be spoken of as an ellipse whose eccentricity is zero." This mandrel of course
may be made of one piece; but the preferable construction is to form it of a
stem T, upon which the sections m, mm", &c., are slid and held in position by
suitable headless set-screws K. The nut on the end of the mandrel also serves
to hold all the sections in place upon the stem.
The method of operation of the invention is the following:-
The heated ingot I being placed on the bracket C, the lever P is given a
movement sufficient to open the valve into the valve chest e' and the inflowing air
or steam forces the piston rod H and a mandrel M forward, so that the mandrel
passes into the ingot and into the passes of the rolls. When the first section m has
entered the ingot, the internal diameter of said ingot being a little greater than the
longer diameter or axis of the said first section m, it picks it up and forces it into
the first pass of the rolls R R, the mandrel stopping at this point and remaining at
rest during the process of rolling which follows. The rolls pull the ingot through
them into the second section m', of the mandrel, thereby reducing it from the form

page_text: shewn at O in dotted lines, Fig. 8, to that shewn in full lines O¹, in the: same
figure.
From this set of rolls the pipe is forced on to the next section, (m" of the
mandrel,). coming on to it in the shape 0', as shewn in dotted lines in Fig. 9.
These rolls crush and reduce the pipe down to the shape O", as shewn in full lines
in Fig. 9. In the same manner the reduction on the remaining sections of the
mandrel and within the remaining sets of rolls goes through the shapes (0 to
the finished shape O, as shown in Figs. 10, 11, 12. The final section of the
mandrel is a true circle, as is also the pass in the last set of rolls, and the product
of the rolling mill is a seamless tube of perfect circular cross-section and equal
thickness of walls throughout. By reversing the lever P the steam or air enters
the other end of the cylinder E and withdraws the mandrel M. At the last portion
of the travel of the cross head N the lever W" is struck, which opens the valve W
and permits water to enter through the pipe w and fill the perforated pipe X, from
which it drops upon the mandril, cooling the same. When another ingot has been
placed in the bracket C and the mandrel is given its forward motion the spiral
spring S operates the lever W" to close the valve W and the flow of water is
shut off.
The advantages of this improved rolling mill are evident in its simplicity and
lightness, combined with strength. It is obvious that with a break down at any
point produced by any cause, the part damaged can be readily replaced without
disturbing other parts of the rolling mill. It is also evident that as the pipe passes
off one section of the mandrel on to the next, coming on to it in the shape shown in
any one of the dotted line figures, Figs. 8 to 12, it is positively held and centered
by the mandrel section by virtue of the fact that the major axis of the elliptical
pass of the rolls at this point is equal to the minor axis of the ellipse to which the
outer surface of the pipe has been formed by the preceding set of rolls, while the
inner surface of the pipe is shaped to an ellipse whose minor axis is just equal to
the major axis of the said mandrel-section. Moreover, in view of the fact that the
main reduction of the pipe by the rolls is always in the direction of the major
axis of the ellipse formed by the pipe's cross section, and that said major axis is
always at right angles to the axis of the rolls, which is parallel to the minor axis y
(reference being made to the dotted section O, Fig. 8). The said reduction is
nearly all done by the bottom portion of the groove in each roll, and little or no
pressure is brought upon the sides of the grooves, so that there is no tendency to
clog the rolls or tear the stock by virtue of the different rates of speed at which
the bottom of the groove and the sides of the same are travelling, on account of
their being nearer to or farther from the centre of the revolving roll. Again,
whenever the action of any set of rolls has worn down the end of the mandrel
section, which terminates in the bight of said rolls, by action of the pipe which is
drawn down over the end of each section to the lesser diameter of the next section,
the sections of the mandrel can be removed, put in a lathe, and have a portion of
their ends turned down to the shape of the next section and the entire mandrel
moved forward on its stem. These operations may be repeated until the mandrel is
entirely worn out and new sections then put on.
It will be noticed that throughout the operation the major axis of the tube is
presented to the minor axis of the mandrel section, leaving a crescent-shaped
opening between the two, and the action of the successive sets of rolls closing the
tube to the form of the mandrel-sections with little or no friction and wear on
the same.
While I have described the passes of the rolls and sections of the mandrel
heretofore in general terms as being reduced copies one of the other, and while such
an arrangement would work, producing a finished pipe of the same thickness of wall
as the original ingot, but of much less diameter, in the preferred form of the
invention the passes of the rolls and the sections of mandrel corresponding thereto
are arranged as shown in the drawings, Figs. 8 to 12, in which the ellipse of the
mandrel-section is of less eccentricity, more nearly approaching the circle than the

page_text: ellipse of the corresponding roll-pass. This being the case, the wall of the pipe
which corresponds to the side of the ellipse is rolled thinner than at the end, and as
said side portion of each ellipse becomes the end portion of the succeeding ellipse,
it is evident that the thickness of wall of the pipe, as well as its diameter, would be
rapidly and evenly reduced, so that the finished pipe can be of any thickness less
than the thickness of the original ingot. At the same time the essential point of
the invention is not lost sight of, to wit: that the dimension of each pass of the roll
which is parallel to the axis of that set of rolls shall be just equal to and not less
than the dimension of the preceding pass of the rolls which is at right angles to the
axes of said preceding set of rolls, so that there need be no work done by the sides
of the grooves of the rolls, but all such reducing work is brought upon the bottom
of the grooves.
It is also evident that while the arrangement of alternating
ellipses specially described herein is the best arrangement of roll passes and mandrel-
sections for the rapid and even reduction of the ingot, yet such reduction might be
brought about by alternating sections of different shapes and irregular form or of
alternating elliptical and circular shapes, so long as the differences in the pass of
each roll and the cross section of the mandrel above referred to are preserved, or so
long as the arrangement of succeeding parallel dimensions by which. all work is
taken from the sides of the roll-grooves is preserved.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what
I claim is :-

angles one to another, the passes of said rolls being of an elliptical form, the major

the succeeding pass together with a mandrel composed of sections equal in length
to the distance between the centre of one set of rolls and the centre of the next,
the cross section of each of said sections of mandrel being an ellipse whose major
and minor axes are parallel to the major and minor axis, respectively, of the ellipse

less eccentricity than the ellipse of the roll-pass, substantially as described.
2. The combination of two or more sets of grooved rolls arranged about at right
angles one to another, the passes of said rolls being of varying shapes, but so

set of rolls, said latter dimension being parallel to the axis of said succeeding set of
rolls, substantially as described.

set of rolls, together with a mandrel consisting of a series of section of varying
shapes approximately corresponding to the shape of the corresponding passes of
the rolls, and arranged so that the least diameter of any one mandrel-section is
exactly equal to the greatest diameter of the succeeding section and parallel thereto,
substantially as described.
5. The combination of two or more sets of grooved rolls arranged about at right
angles one to another, the passes of said rolls being of elliptical form, the major

the succeeding pass, together with a mandrel composed of sections equal in length
to the distance between the centre of one set of rolls and the centre of the next,
the cross section of each of said sections of mandrel being a slightly reduced copy
of the pass of the set of rolls within the bite of which that section of the mandrel
comes, substantially as described.
7. A mandrel consisting of a central stem and a series of elliptically shaped sections
keyed on said stem, the major axis of each section being equal in length to the
minor axis of the preceding section and parallel thereto, substantially as described.
8. The combination of two or more sets of rolls set at right angles to each other,
having elliptical passes with their major axes parallel to the axes of such rolls, and

together with a mandrel of elliptical sections secured on
a stem, the difference
between the major axis and the minor axis of each successive section being similarly
diminished so that the last section of the mandrel is a true circle, substantially as
described.
