PROVISIONAL SPECIFICATION.
An Improved Machine for Straightening Tubes and such like
Articles.
We, ROBERT WOOTTON, of Harborne Road, Edgbaston, Birmingham in the
County of Warwick, Gentleman, and BENJAMIN HEWITT, of Fir Tree Villas,
Waterloo Road, Smethwick, Birmingham, aforesaid, Engineer, do hereby declare
the nature of our said invention to be as follows:-
Our invention has for its object an improved machine for straightening tubes
and other such like articles in an almost automatic manner so as to minimize the
attention of the attendant.
The
Upon a stout bed plate we mount at about the centre a headstock carrying a
hollow shaft driven by pulleys or gearing or other means and carrying also a chuck
fitted with a slide which is supplied by springs so as to keep the slide central or
with springs of unequal power so as to tend to keep the slide not central.
centre of the slide carries a bush or liner of wood, metal or other material through
which the tube passes to be straightened and this bush or liner is held in position
by a gland pivotted on the slide. At each end of the bed we mount a standard or
standards which slide along the bed by means of screws operated in a lug or lugs
so as to bring the standards nearer to, or further away, from the headstock or
centre of the machine. Each of these standards has a hole on a line with the
oxis of the headstock and each carries a bush of wood, metal, or other suitable
material or composition. One or both of these may be split and a lever or weight
applied to hold the tube from turning. As the tube is fed through the machine
the slide moves sufficiently to accomodate itself to inequalities upon the tube in
one direction; but in the other direction such inequalities are pressed into a straight
liue as the tube passes along and thus it is straightened.

We, ROBERT WOOTTON, of Harborne Road, Edgbaston, Birmingham, in the
County of Warwick, Gentleman, and BENJAMIN HEWITT, of Fir Tree Villas,

the nature of our said invention and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement:-
-
Our invention has for its object an improved machine for straightening tubes
and such like articles in an almost automatic manner so as to minimize the
attention of the attendant.

page_text: The
Upon a stout bed plate we mount at about the centre a headstock carrying a
hollow shaft driven by pulleys or gearing or other means and carrying also a chuck
fitted with a slide which is supplied by springs so as to keep the slide central or
with springs of unequal power so as to tend to keep the slide not central.
centre of the slide carries a bush or liner of wood metal or other material through
which the tube passes to be straightened, and this bush or liner is held in position
by a gland pivotted on the slide. At each end of the bed we mount a standard or
standards which slide along the bed by means of screws operated in a lug or lugs
so as to bring the standards nearer to or further away from the headstock or centre
of the machine. Each of these standards has a hole on line with the axis of the 1
headstock and each carries a bush of wood metal or other suitable material or
composition. One or both of these may be split and a lever or weight applied to
hold the tube from turning. As the tube is fed through the machine the slide
moves sufficiently to accomodate itself to inequalities upon the tube in one
direction, but in the other direction such inequalities are pressed into a straight
line as the tube passes along and thus it is straightened.
In order that our invention may be clearly understood and more easily carried
into practice we have appended hereunto a double sized sheet of drawings upon
which we have fully illustrated the nature of our improved machine.
Figure 1, is a side elevation of one of our machines with the bottom part of
the legs broken away.
Figure 2, is an enlarged longitudinal section along the line of tube which latter
is shown in elevation.
Figure 3, is an enlarged front elevation of the chuck A.
Figure 4, is an enlarged elevation of the standard D.
In carrying our invention into effect we mount a headstock B upon a suitable
bed plate Y to which it is firmly secured. This headstock B carries the hollow
shaft or sleeve A' which is driven by the pulley C and forms part of or is
attached to the chuck A into which is fitted the slide a' the movement of which is
controlled by the springs a arranged at each end for the purpose. To the centre
of this slide a² a steel bush or liner a³ is mounted in the intermediate cup or
collar a by which means the bush a³ may remain stationary while the chuck
revolves or it may turn. The bush or liner is retained in position by the gland a
which is pivotted at a and is provided with a slot as which engages with a pin a
on the slide a². In each end of the bed Y the standard D and D are respectively
mounted to have a sliding movement upon the bed and are operated by means of
the handles e and e³ and screws E and E¹ which engage with tapped blocks d
and d' upon the standards D and D₁ by which means the position of the standards D
and D' relatively to the liner a³ may be adjusted as required. Each of these
standards bear a steel bush or liner ds and d³ respectively which are mounted in the
collars d and d in a line with the centre of the sleeve A'.
The action of straightening the tube is as follows:-The tube is fed into the
liner d³ by hand or other suitable means in the direction shown by the arrow R and
as it passes through the chuck and into the liner d the slide a² moves sufficiently
to accomodate itself to inequalities upon the tube in one direction while in the
other direction such inequalities are pressed into a straight line by which means the
tube is straightened. The liner or bush M is inserted within the sleeve A¹ its
position being regulated by the tube K which is placed intermediately between the
bush M and the standard D the movement of the tube tending to keep it in position
in the reverse direction.
The bushes are arranged in the intermediate collars for convenience in altering
the size; and, to prevent the bush from revolving, the collars may be split and
compressed by the weight W which hangs from the gland of the standard D by
the rod w¹.
Any suitable gearing may be substituted for the pullies and the material of the
bushes or liners may be varied to suit the various requirements.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
==
1st. An improved machine for straightening tubes or other such like articles
substantially as herein set forth and shown upon the accompanying drawings.
2nd. In a machine for straightening tubes or other such articles the chuck A
having the slide a carrying the bush or liner a³ substantially as and for the
purpose herein set forth and shown.
