This Invention has for its object improvements in machinery for bevilling the
frames of ships and for like uses.
The frames of ships are commonly constructed of angle iron and this angle iron
as it is received by the ship builder has its two flanges or webs at right angles the
one to the other.
The bevilling of the frame consists in altering the inclination of the webs of the
iron; opening the angle out more or less. In passing from end to end of a single
frame or length of angle iron many different bevils are required. This work is at
the present time performed by hand labour.
According to my Invention I substitute the use of rollers and this I do in the
following manner.
I prepare several pairs of rolls, each to a different bevil and I mount these rolls
at the periphery or ends of the arms of a star wheel. There are two of these star
wheels they are large and massive and each carries one of each pair of rollers.
The axes of the star wheels are parallel they are mounted in a frame and one of
them can be moved to and from the other by screws or by hydraulic gear or other-
wise. The wheels can also be turned about the axes and locked so as to hold any
pair of rollers in proximity and in position to work together. The rollers on each
star wheel are all driven by pinions gearing into a toothed wheel on the central
axis.
The work is performed as follows:-The iron to form the frame being heated is
placed between the rollers having the required bevil which have been previously
brought to the working position and the star wheels are then closed together so as
to cause the rollers to nip the bar. As the rollers rotate they roll out the bar to
the bevil required.
On arriving at the end of the length over which the bevil is to extend the
machine is reversed and the rollers pass a second time over the work and this is

page_text: repeated as often as necessary. The work will usually be commenced with the
pair of rollers having the smallest bevil and when these have done their duty the
work is released, the star wheels are turned round and the next pair of rollers is
brought to the working position. This pair is then employed to increase the bevil
in the parts requiring it and so on one pair of rollers after another being made
use of
Where many bevils are required I can provide two star wheels on each of the
axes and lift the work from one pair of star wheels to the other when required.
Or in some cases I provide all the bevils required on a single pair of rollers.
These rollers are provided with hydraulic or other gear for rapidly separating them
and bringing them together and also for reversing.
The work is then performed by placing the heated bar between the rolls and this
is done first so that the bar is received into the grooves where there is the least
bevil. The rollers are then closed together and the part requiring bevilling is
worked through the rolls. On arriving at the end of this part of the bar the rolls
are opened or reversed or both as the nature of the work may require. When the
work has been advanced as far as it can be in the commencing grooves of the rolls
with the smallest bevil the rolls are opened and the work is shifted laterally to the
next grooves and so on. The work is reheated as often as may be necessary. By
similar arrangements frames of other sectional forms may be bevilled.

Improvements in Machinery for Bevilling and Bending the
Frames of Ships and for like Uses.
I, SAMUEL WILKINSON SNOWDEN, of 72 Mark Lane, in the City of London,
Engineer, 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 machinery for bevilling the
frames of ships and for like uses.
The frames of ships are commonly constructed of angle, tee or channel iron,
and, as received by the ship builder, the flanges and webs of such iron ore at right
angles.to one another.
The bevilling of the frame consists in altering the inclination of the webs of the
irons, opening the angle or angles out more or less or closing them up as required.
And in the same way many varieties of curves in their length are required in such

page_text: framings, and many different bevils between the webs are required in the length of
any single framing.
By my invention, I effect both the bevilling and the curving of the frames with
alternative adjustments of my machine according to requirements.
In order that my invention may be the better understood, I now proceed to
describe the same, reference being had to the drawings hereto annexed, and to the
letters and figures marked thereon.
Figure 1 is an end elevation of my machine.
Figure 2 is a side view of the same.
Figure 3 is a detached detail of the star frames carrying the bevilling rolls.
Upon any convenient form of star frame or drum A, I mount rolls B B¹ of
different bevils at the periphery of the said drum or at the ends of arms of the
star frames which are made large and massive to carry considerable pressure.
I use two or more star frames or drums A, mounted above one another in pairs,
one drum carrying the male or convex rolls B, and the other the female or concave
rolls B¹.
The axes of these star wheels or drums A A are parallel, they are mounted in
the frames C, C, one being carried on fixed bearings, and the other in blocks D D
sliding in guides in the frames, so that the latter star wheel can be moved to and
from the other by a screw E, or by hydraulic gear, or other means.
The said screw E is operated conveniently in the arrangement shown by a worm
wheel F and a worm upon the shaft f, which is driven so as to either lift or depress
the upper star frame by means of the vertical shaft G and hand wheel g.
The star wheels A A can also be turned about their axes together with the
shafts a, a, to which they are keyed by means of the bevel gear b, b, and the
vertical shaft C' and hand wheel d. The said star wheels are locked in place
when adjusted to any desired position, by the lever clutch or by a pawl and rachet
wheel, e.
The star wheels are thus adjusted so as to cause male and female rollers with
similar bevils to be brought opposite to one another to carry out the bevilling of
the frames. To effect the curving of the frames, a set of rolls on the
upper star
frame is adjusted so as to come between two sets of rolls on the bottom star frame,
or vice versa, by which means any desired curving of the frames can be effected.
The rolls B are keyed to axles carried in suitable bearings 61 61 on the star-
frame, the said axles being driven by gear wheels H, of which there is one to each
roll axle, each gearing into the central spur wheel K, which is driven in any
suitable way from the first motion shaft L, so as to be capable of reversal of
motion.
This is effected as shown by double bevil wheels 1, 1, running free on the shaft L
with a sliding clutch M on a feather on the shaft, and lever m, by which either
bevil wheel can be thrown into gear and the direction of rotation of the wheel K
thus reversed. In the middle position of the clutch M it is out of gear with both
bevil wheels, and the spur wheel K remains at rest.
The work is performed as follows:-
The iron to form the frame may be heated or treated cold, and is placed between
the rolls which have the required bevil, and which have been previously brought
to the working position, that is, like male and female rolls are brought opposite to
one another. The star wheels are then closed together so as to cause the rollers to
nip the bar, one of the rollers being caused to rotate by the gearing hereinbefore
described. As the rollers rotate they roll out the bar to the required bevil.
On arriving at the end of the length over which the bar is to extend, the
machine is reversed, and the rollers pass a second time over the work with greater
pressure, and this is repeated as often as necessary. The work may be commenced
by passing the iron through rollers with the smallest change of angle from that of
the right angle, and afterwards the work is released and passed through another
set of rollers with greater bevil, situated alongside the former set of rollers, or upon
a different arm or part of the periphery of the star wheels or drums A. In this

page_text: latter case the star wheels or drums are rotated to bring up to position the various
sets of rollers successively.
Should curving as well as bevilling be required, the lower star wheel is set so
that the upper roller presses on the space between two adjacent sets of rollers on
the lower star wheel or drum.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1st The construction of a ship frame bevilling machine with a number of male
and female bevilled rollers of various bevils, mounted conveniently upon the
periphery of star-wheels or drums, or otherwise, so that any desired pair can be
brought into juxta-position and pressed together by screw or hydraulic pressure,
one of each such pairs of rollers being driven, by gearing or otherwise, to effect the
feed of the bars through the said rollers, substantially as specified.
2nd The construction of a combined ship frame bevilling and curving machine
with pressing rolls of any desired outline mounted upon the periphery of star-
wheels or drums, screw or hydraulically pressed together and adjustable on their
axes, so that the rollers of one star-wheel can be set opposite to the corresponding
rollers of the other star-wheel to effect bevilling, or so that the roller of one star-
wheel can be set to press between two other rollers upon the other star-wheel to
effect curving, one of the said rollers being driven by gearing to effect the feed of
the bars through the said rollers.
