Improvements in Rolling Mills.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co. Patent Agents,
Southampton Buildings in the County of Middlesex, do hereby declare the nature of
this invention to be as follows:-
This improvement relates to what I call universal rolling apparatus; in other
words, to rolling apparatus comprising top and bottom rolls and side rolls and
organized so that these rolls shall be capable of adjustment to suit work of different
sizes and shapes.
The improvement consists in the combination in a rolling apparatus of a bottom
roll, a top roll, side rolls and mechanism for effecting the relative adjustment-between
the said rolls.
In a machine embodying this combination the bottom roll will be shaped to conform
to one side of a bar to be rolled. The top roll will be shaped to conform to the upper
side of such bar and the side rolls will be constructed to conform to the intermediate
faces of the bar. These rolls are not connected together so that the movement of one
will directly impart movement to another, but they are all adjusted by a common
mechanism. The mechanism for adjusting the rolls is capable of being separated at
certain parts and reunited after the manual adjustment of these parts for the purpose
of establishing a different normal or initial relation between the rolls.
The mechanism for adjusting the rolls comprises certain sliding parts.
The side rolls are sustained by pairs of rolls so arranged that they and, the side.rolls
are in the position of the apices of a triangle. In this way the side rolls are well
sustained and yet are relieved from injurious friction.
The improved apparatus comprises a pair of vertical rolls which are arranged one
above the other, a pair of horizontal rolls are. arranged opposite one another and
adjacent to the sides of the said vertical rolls.
The apparatus as hereinafter described is adapted to the production of what are
commonly known as I-beams or girders, the principle of this invention however is
not merely applicable to the rolling of this particular form of bar. The vertical rolls
are made of a shape to correspond with the particular section of beams or girders it
is desired to roll.
There are combined with these rolls guides extending horizontally, the faces of
which are vertical. The material may be passed to the rolls from either side and
hence may be guided into the rolls either by the guides on one side or by those on
the other side. One pair of the said guides will always serve to direct the matorial
properly from the rolls after the rolling operation.
An adjustment between the two vertical rolls is provided by making the upper roll
vertically adjustable. There is also an adjustment between the horizontal rolls and
the guides in the different pairs; this being attained in the present instance by
making both the horizontal rolls and the opposite guides.adjustable towards and from
each other.
The adjustments which have been provided adapt the apparatus to work of different
work and sizes.
Having now given a general explanation of the rolls and guides I will proceed to
give a detailed description of the apparatus.
The lower vertical roll has its journals supported in journal boxes arranged in two
side frames. The right hand journal extends a considerable distance beyond the

page_text: journal box wherein it is supported and at its outer extremity it is shaped to interlock
with a coupling for connecting it with another shaft arranged in line with it, such
shaft being the means of imparting rotary motion to it.
The upper vertical roll bas its journals supported upon bars extending horizontally
beneath them. These bars are simply for taking the weight of the roll and are
sustained by vertical rods passing downwardly from them and connected at the lower
ends by links with levers which are pivoted to the base portion of the apparatus and
have weights attached to their opposite ends. These weights are somewhat heavier
than the rolls and its journals and other appurtenances hence they will always elevate
said roll and its appurtenances when the force ordinarily exercised to hold said roll and
its appurtenances down shall be relaxed. Above the journals of the upper vertical
roll are half boxes which serve to resist the upward movement of the roll and there-
fore to exert upon the roll the pressure which is requisite for the rolling operations.
The side frames are of open construction so as to constitute housings. The edges of
these half-boxes are fitted to the edges of the housings and are guided by the latter
when moved up and down.
Above the said half boxes are screws. These screws extend through the upper
portions of the side frames above the housings therein and engage with nuts which
are fitted into these portions of the side frames. By rotating these screws in one
direction they may be made to force the boxes downwardly and by so doing force.
the upper vertical roll and its appurtenances downwardly so as to reduce the space
between this roll and the lower roll. If the screws are rotated in the reverse
direction they will allow the said upper roll and its appurtenances to rise and so
increase the space between it and the lower roll.
The upper ends of the screws are provided with bevel gear wheels, which engage,
with bevel pinions affixed to a shaft arranged transversely to the length of the screws.
The said shaft constitutes a driving shaft for the mechanism employed to effect the
adjustment of the upper vertical roll and also the adjustment of other parts as will
hereinafter be explained. The said shaft is provided with a fly wheel that may be
operated by hand to rotate the shaft. The shaft may however, if preferred be
combined with means for enabling it to be operated by power.
The said shaft is supported in bearings which are provided with suitable hoxes for
receiving the shaft and which are fitted to vertical rods in such manner that they
may slide up and down along the said rods. These rods are supported on horizontal
sliding blocks. It may here be observed that these horizontal sliding blocks serve to
support the horizontal rolls. The shaft obviously is raised and lowered when the
bearings are elevated and lowered. This raising and lowering of the shaft is
provided to enable it to always maintain its relations with the screws regardless of
change in position of the latter brought about by rotating them for the purpose of
adjusting the upper vertical roll. The said shaft is coupled to the screws by coupling
pieces consisting of collars fitting the shaft loosely and transverse tubular extensions-
extending over cylindrical extensions at the upper ends of the screws above the gear
wheels. The said cylindrical extensions where they fit within the coupling pieces
are provided with circumferential grooves. Screws pass through the coupling pieces
and extend into the said circumferential grooves and thereby fasten the coupling
pieces and the screws together, while still permitting the said screws to rotate.
to it.
The right hand journal of the upper vertical roll extends considerably beyond the
bar upon which it rests, and at its outer extremity it is constructed to interlock with
a coupling serving to connect it to a shaft, whereby rotary motion will be imparted
The shafts which are employed to drive the rolls may be of ordinary kind, we
have not deemed it necessary to describe them saving only to add that the shaft
which drives the upper vertical roll may be supported in such a manner that it may
assume inclined positions to adapt it to the raising and lowering of said rolls.
The side frames have extending from their outer sides lateral projections, the left
hand side frame having two parallel and opposite lateral projections, one near the
front edge and one near the rear edge, and the right hand side frame having
similar projections. The sliding block on the left hand side has its inner portion, or

page_text: in other words, that portion which is nearest the vertical rolls fitted between the two
lateral projections of the side frame. The adjacent surfaces of the projections and
inner portions of the block are rabetted and grooved so as to form shears or ways
along which the block may slide towards and from the vertical rolls. The outer
portion of the said block extends beyond the ends of the projections and at the
extremities has affixed to it rods which are secured to the guides hence whenever
motion is imparted to the said blocks a corresponding motion will be imparted to the
guides.
The right hand sliding block is constructed like the left hand one and is fitted to
the projections of the side frame in a manner similar to that in which the left hand
block is fitted to the projections of the left hand side frame. Rods are at one end
secured to the extremities of the outer portion of the right hand block beyond the
projections of the right hand side frame and at the other end these rods are secured
to the guides so that when the right hand block is moved, the said guides will be
similarly moved.
The lateral projections of the side frames are provided with pockets into which are
fitted nuts for engaging with screws. These screws are provided with plain shanks
which fit in bearings in the sliding blocks. The shanks of the screws are provided
with circumferential grooves. With these grooves engage the forked ends of plates
which are secured to the sliding blocks. The screws are thus secured to the sliding
blocks so as to be incapable of longitudinal movement independently of the sliding
blocks. Owing to this it will be obvious that when the screws are rotated, the nuts
will cause them to move longitudinally and their longitudinal movement will impart
a movement to the sliding blocks towards or from the rolls according to the direction
in which the screws are rotated.
The right hand screws are provided with bevel gear wheels which engage with bevel
gear wheels affixed to a horizontal shaft. In this manner the said screws are secured
together. In like manner the left hand screws are provided with bevel gear wheels
engaging with other bevel gear wheels on a shaft corresponding to the said horizontal
shaft and are thus geared to operate in unison. The right hand pair of screws are
driven through an inclined shaft from an upper horizontal shaft. The left hand
screws are similarly driven from the said upper shaft. It will be seen therefore that
the two pairs of screws are driven in unison and correspondingly and from this it will
be obvious that the rolls and guides will be moved correspondingly, toward or away
from the said rolls.
The side frames have formed in their opposite or adjacent sides, recesses for the
accommodation of the guides when they are adjusted as far as they can be adjusted
away from each other.
The upper horizontal shaft is provided at the ends with bevel gear wheels which
engage with other bevel gear wheels affixed to rotate with the aforesaid inclined shafts.
The gear wheels have long hubs and are engaged by feathers or splines with the
inclined shafts hence they may slide along the said shafts when the upper horizontal
shaft is raised or lowered through the action of the screws and yet will rotate the said
inclined shafts. The gear wheels on the end of the upper shaft have long hubs formed
with or secured to them and are engaged with the said shaft by feathers so that this
shaft shall be incapable of rotating without imparting rotary movement to them and
withal so that they can slide lengthwise of the said shaft. The boxes or bearings
which receive the said shaft and are free to slide along the rods, embrace the hubs of
the bevel wheels on the upper shaft hence when the sliding blocks which slide on rods,
move towards and from the rolls, the bevel wheels will be moved correspondingly
along the upper shaft. The hubs of the said bevel wheels are also embraced by yokes
and these yokes embrace the hubs of the bevel wheels on the inclined shaft. These
yokes are so connected with the hubs of the bevel wheels that there can be no relative
movement between the yokes and hubs of the wheels, saving only as regards a rotary
movement of the wheels. These yokes cause the bevel wheels to slide along the
said shafts when the upper shaft is raised and lowered by the action of the
screws.

page_text: It will be understood that when the said upper shaft is rotated, it will by operating the
screws adjust the upper roll vertical relatively to its. fellow and also adjust the hori-
zontal. rolls of the opposite pair of guides laterally with relation to the vertical rolls.
By this means the several rolls and the guides may be adjusted-into-positions adapting
them for, successive rollings, of any given, bar, or mass of metal, for the purpose of
reducing it.to a bar; beam on girder, of desired configuration.
At the lower and the inclined. shafts are provided with bevel gear wheels, which are
engaged with them by means of keys, and engage with and impart motion to the
bevel wheels on the screws. Around the shanks of the said screws are collars which
are made in two sections secured together by bolts. They are provided, with sockets
receiving the ends of the inclined shafts. These shafts are provided near tho, lower
ends. where they enter the sockets, with circumferential grooves and the sockets are
provided with screws which enter the circumferential grooves, thus securing
the shafts within the sockets and thereby connecting them with the shanks of the left
hand screws.
By means of the connections which have been just described for securing the bevel
gear wheels on the lower end of the inclined shafts in operative engagement with their
corresponding bevel wheels, it is possible to disconnect the former,.elevate them and.
their shafts, then make adjustments of the screws which are driven through; the
said. shafts and afterwards restore the connections so as to make the said screws again.
operate through the said shafts. This is advantageous because where a different shaped
or sized bar is to be produced, the mechanism will be reorganized or specially, adapted,
to the doing of that work and afterwards restored to such operative condition that all.
the adjustments can be effected by the rotation of the upper shaft.
Now a description will be given of the manner in which the horizontal rolls.are
supported and. how they are adjusted through the adjustment of the sliding blocks.
Each of these rolls has a single journal and this is located on the bottom and fits into
a supporting block which rest on the journals of the lower vertical roll. To better
adapt them to do this, they are curved on the under side to conformn to the circum-
ference of the said journals. These blocks are connected by bolts with the sliding
blocks, the block of one of the horizontal rolls being connected by bolts with the left.
hand sliding block, and the block of the other roll being connected by bolts with the
opposite sliding block.
The horizontal. rolls are not supported against the metal being rolled, by, their
journals. These journals being employed for securing the adjustment of the said.
rolls. Each of the horizontal rolls is sustained during work by two supplementary.
rollers, arranged so as to bear upon the said horizontal roll at different points. The
centres of each pair of supplementary rolls are arranged relatively to the horizontal
roll that the axes of the said roll and the axes.of the said two supplementary rollers:
are in the position of the points of the apices of, a triangle.
The supplementary rollers are supported in the sliding blocks. The sides of
these blocks which are towards the vertical rolls have pockets. or. recesses formed in.
them, and the supplementary rollers extend into these pockets. or recesses. The.
journals of the said rollers fit in half boxes in the edges of the sliding blocks. above
and below the pockets or recesses thereof.

Improvements in Rolling Mills.
1, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 improvement relates to what we call universal rolling apparatus; in other 5

page_text: words, to rolling apparatus comprising top and bottom rolls and side rolls and
organized so that these rolls shall be capable of adjustment to suit work of different
sizes and shapes.
The improvement consists in the combination in a rolling apparatus of a bottom
roll, a top roll, side rolls and mechanism for effecting the relative adjustment between
the said rolls.
In a machine embodying this combination the bottom roll will be shaped to conform
to one side of a bar to be rolled. The top roll will be shaped to conform to the upper
side of such bar and the side rolls will be constructed to conform to the inter-
mediate faces of the bar. These rolls are not connected together so that the movement
of one will directly impart movement to another, but they are all adjusted by a
common mechanism. The mechanism for adjusting the rolls is capable of being
separated at certain parts and reunited after the manual adjustment of these parts for
the purpose of establishing a different normal or initial relation between the rolls.
The mechanism for adjusting the rolls comprises certain sliding parts.
The side rolls are sustained by pairs of rolls so arranged that they and the side
rolls are in the position of the apices of a triangle. In this way, the side rolls are
well sustained and yet are relieved from injurious friction.
I will describe an apparatus embodying our improvement and then point out the
novel features in a claim.
In the accompanying drawings Figare 1 is a front elevation of an apparatus
embodying this improvement, certain parts being shown in section. Figure 2 is an
end elevation of the same. Figure 3 is a partial plan and a partial horizontal section.
Figure 4 is a plan view of a sliding block which serves to effect the adjustment of
one of the side rolls. Figure 5 is a side view of one of the side rolls, a block by
which it is adjusted and a portion of the lower roll. Figure 6 is-a transverse section.
of a portion of the lower roll, a side view of one of the side rolls and an. end. view
of the block by which such side roll is adjusted. Figure 7 is a sectional elevation of
certain parts of the gearing. Figure 8 is a sectional elevation of certain other parts
of the gearing. Figure 9 is a detail. Similar letters of reference designate corre-
sponding parts in all the figures.
A¹ A B B designate rolls which together are adapted to roll a bar of desired
shape. The rolls A' A' are arranged one above the other, their axial lines being in a
horizontal plane. The rolls B B are arranged opposite one another and adjacent to
the sides of the rolls A¹ A2, the axes of said rolls B1 B2 being vertical.
In the present example of this improvement the rolls are adapted to the production
of what are commonly known as I-beams or girders, but this form is adopted as a
inere matter of illustration, for the principle of this invention is not merely applicable
to the rolling of this particular form of bar. It will be seen. that the rolls A¹ A' have
inain portions a, of cylindric form, angular portions a¹ a², at the sides of the cylindric
portions, and smaller portions as a', at the sides of the angular portions a' a². These
smaller portions a' a' may be substantially cylindrical.
Reference to Figure 1 will make it apparent that the rolls will produce an I-beam
or girder with the web in a horizontal position and it will be readily seen that the
cylindric portions a of the rolls A' A' form the web or body of said beam or girder;
that the angular portions a¹ a³ of said rolls form the inner or opposite sides of the
flanges of the beam or girder, and that the smaller cylindric portions a* a*, form the
edges of the flanges. The outer sides of the flanges or heads of the beam or girder
are formed by the rolls B³ B.
There are combined with these rolls, guides CCCC. These guides are repre-
sented as extending horizontally, but their faces are vertical. The material may be
passed to the rolls from either side and hence may be guided into the rolls either by
the guides CC, or by the guides CC. One pair of guides will always serve to
direct the material properly from the rolls after the rolling.
An adjustment between the two rolls A' A³, is provided. This, as shown, is .
attained by making the upper roll A' vertically adjustable. There is also an adjust-
ment, between the rolls B B and the guides in the different pairs; this being attained!

page_text: in the present instance by making both the rolls B' B' and the opposite guides
adjustable toward and from each other.
The adjustments which have been provided adapt the apparatus to work of different
kinds and sizes.
Having now given a general explanation of the rolls and guides, I will proceed to
give a detailed description of the apparatus which we have illustrated.
The lower roll A has its journals as a supported in journal boxes arranged in two
side frames D¹ D². It will be observed that the journal a³ extends a considerable
distance beyond the journal box wherein it is supported and that at the outer extremity
it is shaped to interlock with a coupling for connecting it with another shaft arranged
in line with it, such shaft being the means of imparting rotary motion to it.
The roll A has its journals a' a supported upon bars a, extending horizontally
beneath them. These bars are simply for taking the weight of the roll and are
sustained by vertical rods a 10 passing downwardly from them and connected at the
lower ends by links a" with levers a¹, which are fulcrumed to the base portion of
the apparatus, and have attached to them weights a¹. These weights are somewhat
heavier than the roll A' and its journals and other appurtenances, hence they will
always elevate said roll and its appurtenances when the force ordinarily exercised to
hold said roll and its appurtenances down, shall be relaxed. Above the journals a' a³
of the roll A¹ are half boxes a", which serve to resist the upward movement of the
roll and therefore to exert upon the roll the pressure which is requisite for the rolling
operations. The side frames D₁ D2 are of open construction so as to constitute
housings d. The edges of these half-boxes a" are fitted to the edges of the housings d,
and are guided by the latter when moved up and down.
Above the hoxes a¹ are screws E' E. These screws extend through the upper
portions of the side frames D' D³, above the housings therein, and engage with nuts
which are fitted into these portions of the side frames. By rotating these screws in
one direction, they may be made to force the boxes a downwardly and by so doing
force the roll A' and its appurtenances downwardly so as to reduce the space between
this roll and the opposite roll A. If the screws are rotated in the reverse direction
they will allow the roil A¹ and its appurtenances to rise and so increase the space
between it and its fellow A².
The upper ends of the screws E' E' are shown as having affixed to them bevel gear
wheels ee. These bevel gear wheels engage with bevel gear wheels e e affixed to a
shaft F, extending transversely to the length of the screws. The shaft F constitutes
a driving shaft for the mechanism employed, to effect the adjustment of the roll A¹
and also the adjustment of other parts, as will hereafter be explained. I have shown
the shaft F as provided with a wheel F¹ that may be operated by hand-to rotate the
shaft. The shaft may, however, if preferred, be combined with means enabling it to
be operated by power.
The shaft is supported in bearings f, which are provided with suitable boxes for
receiving the shaft and which are fitted to vertical rods f¹ in such manner that they
may slide up and down along said rods. These rods f1 are supported on horizontal
sliding blocks GG. I may remark in passing that these horizontal sliding blocks G'G'
serve to support the rolls B¹ B. The shaft obviously is raised and lowered when the
bearings a are elevated and lowered. This raising and lowering of the shaft F is
provided to enable it to always maintain its relations with the screws E¹ E³, regardless
of change in position of the latter brought about by rotating them for the purpose of
adjusting the upper roll A¹. The shaft F is coupled to the screws E' E' by coupling
pieces, here shown as consisting of collars fitting the shaft loosely and transverse
tubular extensions extending over cylindric extensions eo, at the upper ends of the
screws above the gear wheels e¹ e³. The cylindric extensions e" where they fit within
the coupling pieces, have circumferential grooves. Screws e°, passing through the
coupling pieces and extending into the said circumferential grooves, fasten the
coupling pieces and the screws E' E' together, while still permitting the screws to
rotate.
It will be observed that the journal a³ of the roll A¹ extends considerably beyond

page_text: the bar a upon which it rests, and that at the outer extremity it is constructed to interlock
with a coupling serving to connect it to a shaft, whereby rotary motion will be
imparted to it. As the shafts which are employed to drive the rolls A¹ A' may be of
ordinary kind, we have not deemed it necessary to illustrate them and we shall not
further describe them, saving only to add that the shaft which drives the roll A¹ may
be supported in such a manner that it may assume inclined positions to adapt it to the
raising and lowering of said roll.
The side frames D' have extending from their outer sides, lateral projections d¹ d³,
the side frame D¹ having two parallel and opposite lateral projections d', one near the
front edge and one near the rear edge, and the side frames D³ having similar pro-
jections d. The sliding block G₁¹ has its inner portion, or, in other words, that
portion which is nearest the rolls A¹ A², fitted between the two lateral projections d¹
of the side frame D¹. The adjacent surfaces of the projections d¹ and inner portions
of the block G' are rabbeted and grooved so as to form shears or ways along which
the block G may slide toward and from the rolls A¹ A2. The outer portion of the
block G extends beyond the ends of the projections d¹ and at the extremities has
affixed to it beyond the said projections d', rods H₁ H³. These rods H¹ H' are
secured to the guides C' C³, hence whenever motion is imparted to the blocks G³,
a corresponding motion will be imparted to the guides CC.
The sliding block G' is constructed like the sliding block G', and is fitted to the
projections of the side frame D³, in a manner similar to that in which the block G¹
is fitted to the projections d¹ of the side frame D¹. Rods H H are at one end
secured to the extremities of the outer portion of the block G beyond the projections d'
of the side frame D2 and at the other end these rods H H are secured to the
guides CC, so that when the block G is moved, the guides C3 C4, will be similarly
moved.
The lateral projections d¹ of the side frames D1 D2 are provided with pockets.d³
into which are fitted nuts for engaging with screws 11 12 13 1. These screws are
provided with plain shanks which fit in bearings i, in the sliding blocks G¹ G². The
shanks of the screws are provided with circumferential grooves. With these grooves
engage the forked ends of plates i¹, which are secured to the sliding blocks. The
screws are thus secured to the sliding blocks so as to be incapable of longitudinal
movement independently of the sliding blocks. Owing to this it will be obvious
that when the screws are rotated, the nuts will cause them to move longitudinally and
their longitudinal movement will impart a movement to the sliding blocks toward or
from the rolls A' A' according to the direction in which the screws are rotated.
The screws II are provided with bevel gear wheels 2. These gear wheels engage
with bevel gear wheels affixed to a shaft 1. In this manner the screws I' I are
secured together. In like manner the screws I¹ 13 are provided with bevel gear
wheels engaging with other bevel gear wheels on a shaft corresponding to the shaft I³,
and are thus geared to operate in unison. The pair of screws 1 [* are driven through
a shaft J' from the shaft F. The screws I¹ I³ are similarly driven through a shaft J
from the shaft F. It will be seen therefore that the two pairs of screws are driven
in unison and correspondingly and from this it will be obvious that the rolls B' B³
and guides C and C and C and C, will be moved correspondingly toward or away
from the rolls A¹ A².
The side frames D¹ D' have formed in their opposite or adjacent sides, recesses d¹º
for the accommodation of the guides when they are adjusted as far as they can be
adjusted away from each other.
The shaft F is provided at the ends with bevel gear wheels ;, which engage with
bevel gear wheels j', affixed to rotate with the shafts J J. The gear wheels have
long hubs, and are engaged by feathers or splines with the shafts J₁ J', hence
they may slide along the shafts JJ when the shaft F is raised and lowered through
the action of the screws E¹ E, and yet will rotate the shafts J1 J2. The gear wheels j
have long hubs, formed with or secured to them and are engaged with the shaft F,
by feathers so that this shaft shall be incapable of rotating without imparting rotary

page_text: movement to them and withal so that they can slide lengthwise of the said shaft.
The boxes or bearings f, which receive the shaft F and are free to slide along the
rods f¹, embrace the hubs of the bevel wheels j, hence when the sliding blocks G G²,
which carry the rods f', move toward and from the rolls A¹ A³, the bevel wheels
will be moved correspondingly along the shaft F. The hubs of the bevel wheels j
are also embraced by yokes ³, and these yokes embrace the hubs of the bevel
wheels. These yokes are so connected with the hubs of the bevel wheels that
there can be no relative movement between the yokes and hubs of the wheels, saving
only as regards a rotary movement of the wheels. These yokes cause the bevel
wheels j¹ to slide along the shafts J¹ J' when the shaft F is raised and lowered by the
action of the screws E¹ E³.
It will be understood that when the shaft F is rotated, it will by operating the
screws E¹ E³, adjust the upper roll A relatively to its fellow A2, and also adjust the
rolls B¹ B, and the opposite pairs of guides C₁ C3 and CC, laterally with relation
to the rolls A¹ A2. By this means the several rolls and the guides may be adjusted
into positions adapting them for successive rollings of any given bar or mass of
metal, for the purpose of reducing it to a bar, beam or girder, of desired con-
figuration.
At the lower end the shafts J¹ Jare provided with bevel gear wheels 1³, which
are engaged with them by means of keys, and engage with and impart motion to the:
bevel wheels on the screws I¹ 12. Around the shanks of the screws I' 1' are
collars. These are shown as severally made in two sections secured together by
bolts. They are severally provided with sockets receiving the ends of the shafts J¹ J*.
These shafts J J are provided near the lower ends where they enter the sockets
with circumferential grooves and the sockets are provided with screws which enter
the circumferential grooves, thus securing the shafts J J within the sockets and
thereby connecting them with the shanks of the screws I' I'.
By means of the connections which have been just described for securing the hevel
gear wheels je in operative engagement with the bevel wheels, it is possible to
disconnect the said wheels j, elevate them and their shafts J J, then make adjust-
ments of the screws which are driven through the shafts J1 J2, and afterwards restore
the connections so as to make the said screws again operative through the shafts J'J'.
This is advantageous because when a different shaped or sized bar is to be produced,
the mechanism will be reorganized or specially adapted to the doing of that work and
afterwards restored to such operative condition that all the adjustments can be effected
by the rotation of the shaft F.
Now a description will be given of the manner in which the rolls B1 B2 are
supported and how they are adjusted through the adjustment of the sliding blocks G'G'.
Each of these rolls Bi B is shown as having a single journal g,. and this is located
on the bottom and fits in a block g'. The blocks g¹ of the rolls B1 B2 rest on the
journals as a of the roll A³. To adapt them the better to do this, they are curved on
the under side to conform to the circumference of the journals. These blocks are
connected by bolts g with the sliding blocks G1 G³, the block g¹ of the roll. B¹ being
connected by bolts with the sliding block G!, and the block g¹ of the roll B'
being connected by bolts g' with the sliding block G.
The rolls B¹ B² are not supported against the metal being rolled, by their journals g.
These journals are employed for securing the adjustment of the rolls. The rolls are
sustained during work by rollers K' K³. There are two rollers K' and they are
arranged so as to bear upon the roll B¹ at different points. They are arranged
relatively to the roll B¹ so that the axis of the roll B¹ and the axes of the two
rollers K', are in the position of the point of the apices of a triangle. The roll B
is sustained by two rollers K³ arranged with relation to it in the same manner as
the rollers K are arranged relatively to the roll B¹.
:
The rollers K K are supported in the sliding blocks G¹ G. These blocks in the
sides which are toward the roll A¹ A³, have pockets or recesses g formed in them, and
the rollers K' K* extend into these pockets or recesses. The journals.of the rollers K' K³

page_text: fit in half-boxes in the edges of the blocks G' Gabove and below the pockets
or recesses thereof. We have shown collars 9 fitted to the ends of the journals of
the rollers K K and connected by rods gs and nuts g with lugs g' formed upon the
blocks.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is ;
1. In an apparatus for rolling metal, the combination of top and bottom rolls, side
rolls, a set of screws for operating the top roll, a set of screws for operating the sile
rolls, shafts and gear wheels connecting the screws, certain of said gear wheels being
detachably fastened to their shafts to allow of the adjustment of one set of screws.
independent of the other, substantially as specified.
2. In an apparatus for rolling metal, the combination of top and bottom rolls, side
rolls, blocks with which the side rolls are connected, screws for effecting the adjust-
