page_text: WILLIAM LONGWORTH and THOMAS PERCY LONGWORTH both of 10 Tipping
Place Bolton, Lancashire, Roller and Tool Makers &c. do hereby declare the nature
of this invention to be as follows:-
The object of our improvement is to apply an apparatus to the ordinary
sliding & cutting lathe so as to opperate the cutting down of the ends & the
sliding, of the rollers, collars & the like at one opperation.
The invention consists in applying a suitable fixing at the back of any sliding
lathe, and mounting upon the said fixing a slide or carriage having one or more
adjustable cutters. To obtain an inward motion of these cutters we attach to the
said slide or carriage, an adjustable link plate, in which said link plate works a
die carried upon a stud on the main lathe saddle or carriage, so that as the main
carriage or saddle moves along the lathe bed for sliding, the back cutters are
brought inward for cutting the sides or ends of rollers, collars or the like at the
same time, in proportion to the inclination of the said link plate.

Improvements
We, WILLIAM LONGWORTH and THOMAS PERCY LONGWORTH both of
10 Tipping Place, Bolton in the County of Lancaster, Roller and Tool Makers,
do hereby declare 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:―
The object of our improvements is to apply an apparatus to the ordinary sliding
and cutting lathe so as to operate the cutting down of the ends and the sliding of
rollers, collars, and the like at one operation. This invention consists in applying
a suitable fixing at the back of a sliding lathe and mounting upon the said fixing
a slide on a carriage having one or more adjustable cutters. To obtain an inward
motion of these cutters we attach to the said slide or carriage an adjustable link
plate. In the said link plate works a die carried upon a stud on the main lathe
saddle or carriage. As the main carriage or saddle moves along the lathe bed for
sliding the back cutters are brought inward for cutting the sides or ends of the
rollers, collars, or the like at the same time in proportion to the inclination of
the said link plate.
Fig. 1 is a longitudinal elevation of our invention consisting of improvements in
turning or sliding lathes. Fig. 2 an elevation of same.

Fig. 4 an enlarged sectional view showing another method we adopt of disposing
the cutters J.
Fig. 5 an enlarged view of the slide or carriage B, and Fig. 6 a plan of the
latter.
In all the figures the same letters are employed to indicate corresponding
parts.
The object of this invention consists in applying the fixing A at the back side
of a turning or sliding lathe and mounting upon the said fixing the slide or
carriage B having one or more adjustable cutters J. To obtain an inward motion
of the cutters J we attach to the said slide or carriage B the adjustable link
plate D. In the link plate D works the die E carried upon the stud G on the lathe
saddle or carriage H. As the main carriage or saddle H moves on the lathe bed I
for sliding the back cutters J, the latter are brought inward for cutting the sides
or ends of rollers, collars, or the like at the same time in proportion to the
inclination of the said link plate D.
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 :-
1. The general arrangement, construction, and combination of parts composing
the improvements in turning and sliding lathes, as herein before described and as
illustrated in the annexed drawings.
2. The use of the aforesaid apparatus for sliding and cutting down rollers, collars,
and the like at one operation, substantially as described.
3. The use of the aforesaid apparatus for sliding and cutting down rollers,
collars, and the like by the movement of the carriage or saddle, substantially as
described.
