PROVISIONAL SPECIFICATION.
Improvements in Machines for Turning Rollers, Spindles, Rods, or
Shafts, with Parallel or Irregular Shaped Surfaces.
We, WILLIAM BODDEN, of Hargreaves Spindle Works, Oldham, in the County
of Lancaster, Spindle and Flyer Manufacturer, and FRANK ASHTON, of the same
place, Manager, do hereby declare the nature of this invention to be as follows:-
Our invention relates to a method of turning rollers, spindles, rods, or shafts,
or any article with a circular cross section and with parallel or irregular shaped
outline, by means of two turning or cutting tools, both of which are in opera-
tion at one and the same time; the said turning tools being regulated nearer to
or further away from the centre of the article operated upon by means of a shaper,
the contour or outline of the shape varying with the outline of the article
operated upon.
Our machine consists of a bed mounted on suitable legs; the bed is prepared
for a travelling table which moves in a longitudinal direction on the bed; the
travelling table carries the headstock and footstock between the centres of which
the roller, spindle rod or shaft is caused to revolve.
The turning or cutting tools are carried by sliding carriages, one on each side
of the bed, the motion of the carriages being in a direction across the above
mentioned bed. The sliding carriages are so arranged that the cutting or turning
tools are opposite each other.
The position of the cutting tools with respect to the distance from the centre of
the article operated upon is under the control of a shaper, the longitudinal outline
of the shaper being so constructed as to produce any required longitudinal outline
on the article operated upon. The said shaper is so placed as, by the longitudinal
motion of the above mentioned table to produce an up and down motion of a
vertical slide; this up and down motion of the vertical slide is converted into a
motion backward and forward of the above mentioned carriages by means of
inclined planes, so that the up and down motion produces an in and out motion of
the cutting tools, thus producing any desired shape or outline on the roller, spindle,
rod or shaft operated upon.

page_text: place, Manager, 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:-
Our invention relates to a method of turning rollers, spindles, rods, or shafts
or any article with a circular cross section and with parallel or irregular shaped
outline by means of two turning or cutting tools, both of which are in opera-
tion at one and the same time; the said turning tools being regulated nearer to or
further away from the centre of the article operated upon by means of a shaper, the
contour or outline of the shaper varying with the outline of the article
operated upon.
The nature of this invention and the manner of carrying the same into practical
effect will be readily understood from the following description on reference to the
accompanying drawings.
On Sheet 1, Fig. 1 is a front elevation shewing so much of a machine for turning
rollers spindles rods or the like as is necessary to illustrate our invention.
On Sheet 2, Fig. 2 is a transverse section thereof and Figs. 3 and 4 shew in
detail, parts hereafter described.
Our machine consists of a bed a mounted on suitable legs; the bed a is pre-
pared for a travelling table b which moves in a longitudinal direction on the bed a;
the travelling table carries the headstock c and footstock c¹ between the centres of
which the roller, spindle, rod or shaft, shewn dotted at d, is caused to revolve.
с
The turning or cutting tools e c¹ are carried by sliding carriages f f¹, one on
each side of the bed a. The sliding carriage f, f¹ are so arranged that the cutting
or turning tools are opposite each other.
The position of the cutting tools e e' with respect to the distance from the centre
of the article operated upon is under the control of a shaper g, the longitudinal
outline of the shaper g being so constructed as to produce any required longitudinal
outline on the article d operated upon. The said shaper g is so placed as by the longi-
tudinal motion of the above mentioned table b (by which it is carried as shewn) to
produce an up and down motion of a vertical slide h h carrying a bowl * running
on the shaper g. This up and down motion of the vertical slide h h', is converted
into a motion backward and forward of the above mentioned carriages f f' by
means of inclined planes i, i, acting against the faces k, k, fitted to the adjustable
parts,, on the carriages f, f', as seen detached in reversed elevation at Fig. 3
and partial sectional plan Fig. 4. The said pieces are held against the inclines
by the weighted chains m m' attached to the carriage f f'.
Thus the up and down motion of the slide produces an in and out motion of
the cutting tools e e¹, thereby producing any desired shape or outline on the roller,
spindle, rod or shaft operated upon.
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:-
The combination with a longitudinally moving table and shaper, of transversely
sliding carriages upon which the cutting tools are fitted, the distance of the tools
from each other being regulated by inclined planes on a slide the position of
which is regulated by the shaper, substantially as hereinbefore described and
illustrated by the annexed drawings.
