Improvements in or relating to Apparatus for Swaging or Rolling
Metal Tubes.
We, BENJAMIN PRICE, of "Brentburn," Corporation Road, Newport, Monmouth-
shire, Engineer, and CHARLES WILLIAM EARLE MARSH and RICHARD LAYBOURNE,
Civil Engineers, of The Isca Foundry, Newport, Monmouthshire, do hereby declare
the nature of this invention to be as follows:-
This invention has for its object improvements in or relating to apparatus for
swaging or rolling metal tubes by reducing and extending hollow ingots on
mandrils such as described in the Complete Specification of Price's Patent
No. 6283 of 1894.
In carrying out the present invention we may use a pair of rolls or swaging
devices having portions of their peripheries for the operative parts while other
portions of the peripheries of the rolls may be made with a smaller radius and
constitute the gaps or if found desirable sectors that form portions of rolls or
rollers with eccentric grooves may be used. A crank shaft (or other suitable
means) transmits a reciprocating movement to a housing in which the swaging
devices are journalled or pivotted or otherwise suitably mounted for instance non-
pivotted.
To bring the swaging devices into one and the same position on coming in
contact with the ingot pinions on the shaft of the rollers or swaging devices and
gearing with racks secured to the base or other suitable racks may be used or links
jointed at both ends one end to a crank or crank pin on the roll or sector or other
swaging devices and the opposite end to the base or fixed part of the frame or suitable
guides or slots with sliding blocks may be advantageously adopted. The swaging
devices according to our present invention may advantageously be rolls or sectors
journalled or mounted in the housing or bearings with their shafts or the axis on
which they turn in a vertical line. They may however be placed in any other
desirable position.
If the shafts are dispensed with the swaging devices may be pivoted or carried
in the housing in any other desirable manner, they may also be actuated and their
grooves controlled and maintained in their same relative positions on coming in
contact with the ingot as well as through the entire operation by using suitable
guides or fixed slotted links in the slots of these links pins which are fixed near
the peripheries of the swaging devices are mounted with sliding blocks so that
with the reciprocating movements of the swaging devices the pins with their blocks
describe a to-and-fro motion in the suitably shaped slots of the links. The swaging
devices or rolls may however be controlled and the grooves maintained in their
proper relative positions by any other suitable means.
The aforesaid main crank shaft is provided with a cam or other suitable device
which by means of suitable intermediate mechanism controls the rotation and
advance of the ingot with its mandril periodically .e. intermittently.
The ingot to be rolled is placed on a mandril which is supported and held in a
sleeve or other equivalent or suitable device mounted on brackets and movable

page_text: therein respectively lengthwise and rotatively. The rotary and forward movement
of the ingot is thus normally governed by the movement of the parts operating
the rolls or swaging devices.
In some cases the rolls or swaging devices may each have two or even more
grooves formed in them to enable them to operate upon two or more tubes simul-
taneously or consecutively in which case each groove may work its ingot in the
same direction or they may be worked in opposite directions.
Each roll or swaging device may also be provided with one, two, or more gaps
and operating sections the grooves in this case may all be of the same size or they
may be of different sizes so that it is possible to roll tubes of different sections in
the same mill without changing rolls. In operation, the housings with the swaging
devices or rolls are brought back as far as possible towards the feed mechanism
at which place the space between the rolls is sufficiently large to introduce the
forward end of the ingot (which has been previously pierced or cast hollow or
formed with a passage therethrough in any suitable manner) to be treated between
them. The mandril on which the ingot has advantageously been previously placed
is suitably held in the sleeve by any convenient means for instance by two or more
grips pivoted in the sleeve or a suitable chuck or other suitable device may be
used.
The whole mechanism is now started by the application of suitable motive power
to the crank shaft and the housings with the swaging devices are carried forward
and at the same time the links or the slide blocks in the slots are brought into
action and the swaging devices travel on the ingot placed between them the result
being that a short length of the ingot is operated upon (i.e. considerably reduced
and elongated) the grooves in the rollers or swaging devices being suitably formed
for this purpose. When the swaging devices pass over the ingot on the mandril
the sleeve in which the mandril is supported is by means of the cam or other suit-
able device moved back (the grips releasing the mandril or adapted to slip
longitudinally thereon sufficiently for that purpose) leaving the mandril with the
ingot held by and between the swaging devices and at the same time the mandril
must be sufficiently grasped by the grips or otherwise held in the sleeve to prevent
its being moved by the action of the rolls. The return stroke of the housings is
then completed and the cam or feed is now again in action and moves the sleeve
with the mandril and its ingot (which is now liberated) a suitable distance forward
(the ingot being sufficiently compressed on the mandril as to enable this being
done) and at the same time rotates them sufficiently to cause any fins or webs
formed on the ingot to be reduced or removed during the next operation of the
swaging devices, the operation is then continued the feed forward of the mandril
and ingot being such that a portion of the latter operated upon during the previous
forward stroke together with a fresh portion being treated each time the result
being that as the ingot gradually passes beyond the reach of the rolls or swaging
devices it has been reduced to the same diameter as that of the smallest parts of the
grooves called into action.
A concentric part or parts may if desired be provided on the rolls or swages in
combination with the eccentric grooves or the eccentric grooves may be other than
regular in their eccentricity that is the breadth and depth of said grooves may
first quickly diminish for a short length and then very gradually diminish for a
prolonged portion of their length.
The feed forward of the ingot is thus effected when the ingot is released by the
rolls or swaging devices so that the ingot and mandril can be freely moved forward
and the return movement of the sleeve is effected when the ingot and mandril are
pressed by the swaging devices and as a result the mandril with the ingot passes
further and further through the rolls with the ingot.
The tubes may be either cold or hot drawn to finish if desired after they are
rolled or swaged.
Instead of feeding and turning the ingot when the rollers or swaging devices are
at their extreme backward position this may be done when the rollers or swaging

page_text: devices are at their extreme forward position or it may be turned and fed between
the rollers both when the rollers are at their extreme backward and forward
position.
Other means may obviously be employed to accomplish as described the move-
ment of the housings ingot mandril and swaging devices without departure from
the essential features of this invention and the described arrangements are therefore
only intended as examples for carrying out the present invention.
Instead of the foregoing improved feed mechanism we may if desired use any
other suitable feed mechanism or method or means of feeding the ingot or metal
object for instance we may if desired employ the feeding arrangement described
in Price's aforesaid Patent.

Improvements in or relating to Apparatus for Swaging or Rolling
Metal Tubes.
We, BENJAMIN PRICE, of "Brentburn," Corporation Road, Newport, Monmouth-
ahire, Engineer, and CHARLES WILLIAM EARLE MARSI and RICHARD LAYBOURNE,
Civil Engineers, of The Isca Foundry, Newport, Monmouthshire, 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 has for its object improvements in or relating to apparatus for
swaging or rolling metal tubes by reducing and extending hollow ingots on
mandrils such as described in the Complete Specification of Price's Patent
No. 6283 of 1894.
And in order that the present invention may be easily understood and readily
carried into practice we will proceed to fully describe same with reference to the
drawings hereunto annexed.
Referring firstly to Figs. 1, 2, 3, 4 and 5-Fig. 1 is a side elevation (part broken
off exposing sector R with the ingot W on the mandril O partly reduced) showing
apparatus for rolling tubes on mandrils from hollow ingots according to the present
invention.
Fig. 2 is end view of Fig. 1.
Fig. 3 is a plan partly in section of Fig. 1.
Fig. 4 is a sectional view of a pair of sectors R R with mandril O and ingot W
in between.
Fig. 5 is end view of same-looking in the direction of the arrows 1, Fig. 4.
In the apparatus shown in Figs. 12 and 3 the main crank shaft M is journalled
in the base H (these parts being similarly marked in other figures of the drawings)
and has motion imparted to it from a suitable source. The main crank shaft M
transmits the necessary movements to the mandril 0 and ingot W to feed and turn
the latter and to the sectors or swaging devices R R for the purpose of extending
and shaping the hollow ingot W into a tube of the desired form shape and thick-
ness of wall in one or more passages between the operating parts of the sectors R R
between which it (the ingot W) remains the whole time.
When the sectors R R are at their extreme backward position that is nearest
the feeding mechanism the space formed by the grooves between them is large
enough to admit of the forward end of the ingot W which has been previously

page_text: made with a hole or had a hole formed therein of a suitable diameter and placed
on the mandril.
On the forward stroke of the housing N with the sectors R R (which is accom-
plished by the aforesaid main crank shaft M by means of the connecting rod H²
operated by the crank pin H³ the rocker N2 and the links or pitmen Ni pivotted
to N) the sectors R R turn on their axes and the grooves therein which are the
operating portions act on a portion of the ingot W and considerably reduce and
extend it upon the mandril 0. The sectors are actuated and their grooves con-
trolled and maintained in their same relative positions on coming in contact with
the ingot as well as through the entire operation by the slotted link R2 secured to
the guide bars R³ which are secured to the base H¹. The sectors R R are provided
with pins e secured near their peripheries (with suitable guide blocks mounted
thereon) which when the housing N with the sectors R R are reciprocated on the
base Hi between the guide bars R³ describe a to-and-fro motion in the suitably
shaped slot of the links R2 by this means the sectors are forced to make a partial
rotation in opposite directions as they travel to and fro on the ingot placed between
them.
The peripheral speed of travel imparted to the operative surface of the sectors
or swaging devices R R should advantageously be made to exactly correspond with
the speed of travel of the axis of each said sector R .e. these should be uniform
so as to produce a true rolling motion on the ingot W.
The turning and feeding of the ingot W and mandril is governed by the
cam M mounted on the second motion shaft M2 which is driven from the main
crank shaft M by means of the toothed wheels M³ M³ this cam has two working
grooves one for turning and the other for advancing the mandril and ingot
periodically .e. intermittently. When the sectors R R have gripped the ingot W
(on the mandril 0) the sleeve A¹ in which the mandril is held is (by means of
the cam M lever 1 keyed to shaft P3 on which is keyed the forked device O¹ the
latter embracing and controlling the longitudinal movement of the said sleeve A¹)
moved back in the support B attached to the base H¹ without the mandril 0-this
result being obtained because the cotter is not driven through the mandril O but
wedged or forced against its side only forcing it against the side of the hole formed
in sleeve A for its reception leaving the mandril O and ingot W held by and
between the sectors R R that is to say the sleeve A¹ slides back upon the mandril O.
The mandril O is sufficiently secured by frictional contact in the sleeve A¹ by
the cotter to prevent its being moved by the swaging action of the sectors R R
upon the ingot W.
When the return stroke of the housing N with the sectors R R is completed the
cam M¹ is again in action and moves the sleeve A¹ with the mandril O and ingot W
(which is now liberated by the sectors) a suitable distance forward by means of
the cam M levers P and forked device 01 (the ingot being sufficiently compressed
on the mandril O as to enable its being done) to expose a fresh portion to the next
attack of the operating sectors R R and at the same time rotates said mandril and
ingot by means of the cam M. lever N³ link P2 and crank A2 advantageously
through an angle of 90° to cause any fins that may have formed on the ingot W
during the previous attack of the sectors R R to be removed during the following
attack; the sleeve A¹ has a keyway in which a key secured to the crank A2 slides
to allow of the forward and backward movement of the sleeve A¹ in the crank A²
independently of the rotative movement of the sleeve A'; the feed forward of the
ingot W and mandril ( as well as the turning thereof is thus effected when the
ingot is released by the sectors R R so that the ingot W and mandril O may be
freely moved forward and the backward movement of the sleeve A¹ is obtained when
the ingot Wand mandril are gripped by the operative portions of the sectors R R
and as a result the mandril and ingot passes step by step further and further
between the sectors which thus operate on the successive portions of the ingot as
it is turned and fed forward intermittently.
In the apparatus shown in Figs. 6 and 7 the sectors are replaced by the well-

page_text: 66
known gapped rolls i journalled in the housing N (the latter being reciprocated
by the rod H2, rocker N2 & link N' as before) with their axes in a horizontal plane
the rolls RR have portions of their peripheries for the operative parts whilst the
other portions made with a varying smaller radius constitute the enlarged space
or gap." We do not however confine ourselves to any exact proportions and
shape shown as these may be varied to a considerable extent to suit differ-
ing conditions. To bring the rolls R R into one and the same position on coming
in contact with the ingot W we mount pinions S S on the shafts of the rollers R R
which roll upon toothed racks H H secured to the base H. The feed and turning
movements of the mandril 0 and ingot W is effected by the cam M-on the main
shaft M-which governs (by means of the cam-operated pin P¹ intermediate link P
ratchet D shaft D sprocket or chain wheel D¹ the endless chain C sleeve A¹ and
the screw spindle A) the advance and rotation of the mandril O and ingot W step
by step when liberated by the rolls R R. The boss L of the saddle B has a screw
thread cut to receive the screw A.
The sleeve A is provided with a feather or key adapted to slide in a long groove
or keyway running longitudinally of the screw spindle A so as to allow the said
spindle to slide either forward or backward through the sleeve A¹ and thus the
partial revolution of the sleeve will cause the screw spindle A to rotate and as a
result to advance or retire through the boss L of the saddle B according to the
direction of revolution of the said sleeve.
The saddle B is capable of sliding to and fro on the bed B¹ for the purpose of the
first adjustment and introduction of the forward end of the ingot W (on the
mandril 0) between the operating surfaces of the rolls R R that is before the com-
mencement of the swaging operations and the saddle B may then be firmly fixed
to the bed B by any suitable means; or the saddle B may be left somewhat free
on the bed B¹ so that it may "give or move to and fro with the ingot W and
mandril O in case the rolls do not have a true rolling motion when travelling on
the ingot.
"
The pawl of the ratchet D2 is put in gear and imparts motion to the shaft D and
sprocket wheel D¹ and thence through the endless chain C sleeve A¹ and the screw
spindle A to the mandril 0 (with the ingot W) fixed to the said screw spindle A.
For the purpose of moving the saddle B into any desired position on the bed B₁
the shaft D has a keyway cut from one end to the other and in which a key secured
in the sprocket wheel Di slides by this means it is immaterial in what position the
saddle B may be on the bed B₁ the screw spindle A will always be capable of
receiving motion from the shaft D.
The shaft D projects through the bed B¹ at C2 for the purpose of placing a key or
spanner thereon to turn the screw spindle A back after the hollow ingot or tube
has been extended to the desired size this of course can only be done when the
pawl of the ratchet D2 is out of gear the shaft D is then free to revolve in either
direction.
The mandril is connected to the feed screw spindle A by a cotter 7 but it may
be secured in any other desirable manner for instance it may be screwed into the
sleeve.
Figs. 8 and 9 show modifications of the feeding and turning mechanism same
being views partly sectional and on a larger scale.
A sleeve A¹ with a serrated face is placed on the screw spindle A and the shaft D
is reciprocated on its axes whereas in the last described example it received a series
of intermittent motions always in the same direction around its axis the movement
of the screw spindle is effected by the sleeve D2 which has a key or feather sliding
in the groove formed lengthwise in the screw spindle A the sleeve D2 is thrown
out of gear by the lever Y and leaves the sleeve A¹ free to turn either way around
the screw spindle A the sleeve A¹ for this purpose has no key or feather but turns
to and fro freely on the screw spindle A' without imparting motion thereto. When
the sleeve D2 is however released or put in gear by the clutch lever Y said sleeve

page_text: is forced against the serrated face of the sleeve A¹ by the coiled spring V and
thereby motion is given to the screw spindle A.
In the arrangement at Figs. 10 and 11 the chain is replaced by a link P2 which
may be connected to a suitable lever on the shaft 1) (Figs. 8 and 9) and gives the
necessary intermittent movements to the screw spindle A through the ratchet 1)²
the said ratchet is provided with a pawl V2 & spring V₁ for the purpose of throwing
it in and out of action.
In Figs. 12, 13 and 14 is shown apparatus similar to that shown and described
with reference to Figs. 1, 2 and 3 but in this case the sectors are replaced by rolls
mounted on horizontal shafts and are turned around their axes by means of the
wheels S S gearing with toothed racks H H secured to the frame H¹.
The device shown in section at Fig. 15 (and end view thereof Fig. 16) is applic-
able for holding the mandril in the sleeve A' instead of the cotter already described
it forms a reliable means of seizing the mandril to advance and turn it and release
it on the return stroke of the sleeve A¹ in the support B this device is applicable
to the apparatus described with reference to Figs. 1, 2, 3, 12, 13 and 14 the two
grips are pivoted in the sleeve A¹ and have a coiled spring 02 pressing against
them at one side the pressure is capable of adjustment by the cap 0 which com-
presses or opens the spring 02 by means of the screw thread cut in the sleeve A¹
and upon which the cap is mounted. When the sleeve A¹ is brought back the
two grips 03 open out and slip over the mandril ) which is held between the
rolls R R with its ingot W but on the forward stroke of the sleeve A¹ the grips 03
immediately seize the mandril 0 and carry it forward with the ingot W the ingot
and mandril at this moment being liberated by the rolls R R for this purpose.
Although we have described two grips it is evident that three or more may be
usefully adopted.
Fig. 17 is a view in elevation of an apparatus with a further modified form of
feeding and turning gear viz.: a self-acting gear.
Fig. 18 is a plan of Fig. 17.
Fig. 19 is a sectional view of the self-acting mechanism.
Fig. 20 is end view of same.
In this arrangement the rolls R R are revolved by the links R2 R2 and pinions S S
mounted on the roll spindles the links R2 R2 are jointed at both ends one end to
the pin on the crank R which is keyed to the roll spindles and the other end to
the standard H³ secured to the base H¹ the rotation of the bottom roll by the
links R R turns the top roll by means of the pinions S S mounted on the roll
spindles.
The movement of the housing N is effected in a similar manner to that already
described. The feed forward of the ingot W and mandril 0 is governed by the
screw spindle 1) which is rotated by means of the worm S7 and wheel S (mounted
on the screw spindle D) shafts D D D wheels 81 S1 S2 S2 S3 S3 one of which S' is
secure to the main crank shaft M.
The mandril is held in position in the sleeve A' by the cap or chuck which is
capable of adjustment by the hand wheel de mounted on the screw the blades
of the chuck are suitably tapered and fitted into the cone formed in the sleeve A¹
for their reception moreover the chuck is guided by the collar. The whole
of this gear is supported in the movable saddle B the said saddle is moved forward
intermittently by the screw D which is provided with a nut C2 enclosed in the
box Cattached to the saddle B.
When the saddle is prevented from moving forward by the pressure of the rolls
on the ingot W and mandril O the nut C2 compresses the spring C3 which is coiled
round the screw spindle D and enclosed in the box C but the moment the rolls
release the ingot the saddle B is pushed forward by the compressed spring C³ a suit-
able distance, this distance being equal to the amount of compression exerted on
the spring by the nut C which has been moved forward by the rotation of the
screw spindle I. The return of the saddle B is accomplished (after the termina-
tion of the reduction of the ingot to the desired size by the rolls) by the friction

page_text: clutch T T one of which T is provided with teeth S to gear with the pinion S
mounted on the shaft S* which latter is driven by the toothed wheels S* from the
same shaft that carries the said worm S--the clutch T rotates in an opposite
direction to the worm wheel Se mounted on the clutch T and the two clutches turn
freely upon the plain part of the screw spindle. The cone T feathered on the
spindle D is capable of being moved lengthwise of the screw spindle by the lever U
the workmen can thus control the direction of revolution of the screw spindle D
by forcing the cone T2 in either clutch and as a result to advance or return the
saddle B. For the purpose of preventing the saddle being carried too far in either
direction on the bed B₁ the hand lever U is connected to a jointed rod U² sup-
ported in the brackets X X the said rod is provided with collars U³ secured in
definite positions thereon which come in contact with a stop piece U attached to
the saddle B thus when the saddle reaches a certain position on the bed the stop
piece U comes in contact with one of the collars U3 and moves the rod U2 which is
connected to the lever U and throws the cone T2 by means of the levers U1 U out
of the clutch and thus stops the rotation of the screw spindle. The turning
movement of the ingot and mandril is obtained by means of the cranks N3 N4 N5
and A (the latter fixed on the sleeve A2) links 12 P3 and shaft D³ actuated by the
cam M mounted on the shaft D7.
The shaft D is made square on which a crank works that it may give the
necessary motion to the crank N3 and sleeve A2 at any position of the saddle B on
the bed B¹.
Instead of a worm and wheel giving a constant rotation to the screw D it may
be arranged to give an intermittent motion to the screw D in which case the
spring C would not be required on the screw spindle D a device is shown in Fig. 21
whereby the spindle has periodic turning movements. The worm S7 at some
portions of its periphery has grooves which run in straight lines whilst the other
parts have grooves inclined in such a manner that they throw the teeth of the
wheel $6 from one groove to the other intermittently and act in a similar manner
to a cam.
The housing N may be coupled direct to the connecting rod without the inter-
vention of the rocker by mounting the crank shaft in a suitable manner in the
base and the rolls may be formed in precisely the same way as those shown and
described in the said Patent No. 6823 of 1894 or modified by making the grooves
other than regular in their eccentricity that is the breadth and depth of said grooves
may first quickly diminish for a short length and then gradually diminish for a
prolonged portion of their length.
The mandril is extracted by suitable means after the operation of rolling is
complete and the tubes may be either cold or hot drawn to finish if desired after
they are rolled.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:
