Improvements in Lathes and other similar Machines.
I WILLIAM BUCKLEY of Millsands Sheffield in the County of York 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 in writing, and on reference to the accompanying drawings, that
is to say:-
My Invention relates to and consists in certain new and useful improvements in the
construction of Lathes and other similar machines which have a revolving motion, the
object of the invention being to regulate the speed and purchase of lathes and similar
machines for turning and boring articles of different diameters, in the most efficient
and economical way, which object I accomplish as follows:-
In carrying out my invention in practice, according to one modification thereof, I
extend the end of the main spindle and also of the counter spindle of a lathe or other
similar machine beyond the back bearings which support or carry the said main and
counter spindles. Upon the projecting ends I place wheels which gear into each
other, the wheels are changeable and I vary the diameter of the wheels to suit the
diameter of the article it is required to turn or bore, by this means the speed of the
lathe or other similar machine is adjusted so that the work can be done in the most
efficient manner and with great economy, whether the article operated on be large or
small.
According to another modification of my improvements, in addition to the main
spindle and the counter spindle of the lathe or other similar machine I apply and use
one or more additional counter spindles which I fix in any convenient position for
gearing with the first counter spindle placed at either side of the lathe or other similar
machine, and I extend the ends of these counter spindles beyond either their back or
their front bearings, and I put changeable wheels upon them varying the diameter of
the wheels to suit the diameter of the article to be turned or bored, as described in the
previous modification.
In order that my invention may be fully understood I have annexed six sheets of
explanatory drawings, in describing which the letters used and marked thereon
are the same for corresponding parts in all the Figures of the drawings.
indicates the changeable wheels. b, the main spindle. c, the counter spindle.
d, the second counter spindle. e, the loose barrel or sleeve. ; the coupling flanges.
g, the cone pulley; and h, the worm and worm wheel.
Figures 1, and 2, Sheet 1, represent and comprise a plan and an end elevation
of my improved lathe geared with changeable wheels a, fixed upon the back ends of
the main and counter spindle b, and c.
Figures 3, and 4, Sheet 2, represent and comprise a plan and end elevation of
a lathe with two counter spindles c, and d, and geared with changeable wheels a,
placed upon the back ends of the counter spindles and with a loose barrel or sleeve
in two parts, with coupling flanges f.

Figures 5, and 6, Sheet 3, represent and comprise a plan and end elevation of a
lathe with a loose barrel or sleeve e, on the main spindle b, and a cone pulley g, on the
counter spindle on the front side of the lathe, geared with changeable wheels a, on the
back ends of the main and counter spindle b, c.
Figures 7, and 8, Sheet 4, represent and comprise a plan and end elevation of a
lathe with two counter spindles c, d, at the front side of the lathe, and a cone pulley g,
on one counter spindle geared with changeable wheels a, on the back ends of the
counter spindles.
Figures 9, and 10, Sheet 5, represent and comprise a plan and end elevation of a
athe with two counter spindles c, d, and geared with changeable wheels a, placed

two parts, with coupling flanges f.
in
Figures 11, and 12, Sheet 6, represent and comprise a plan and end elevation of a
lathe with a worm and worm wheel h, and with two counter spindles c, d, geared with
changeable wheels a, on the back ends of the counter spindles.
As illustrating the steps in the transmission of the driving motion in my improved
lathes it may here he stated that, as shown at Figure 1, Sheet 1, of my drawings,
there are three pairs of intermediate wheels marked 1, and 2; 3, and 4; and 5, and 6,
which are used to transmit the driving motion from the cone pulley g, to the change-
able wheels a; wheel 1, which is attached to the cone pulley g, revolving on the
main spindle c, gives motion to the loose barrel or sleeve e. Wheel 3, gives motion
to the wheels 4, and 5, cast or placed together and which are free to revolve on the
main spindle c.
Wheel 6, is keyed to the counter spindle e, and is driven by the
wheel 5. The changeable wheels a, convey motion from the counter spindle e, to the
main spindle c.
The wheels 2, and 3, will slide out of gear and the cone pulley,
can be attached to the wheels 4, and 5; and the lathe is worked with the wheels 5,
and 6, and the change wheels in gear. And as seen at Figure 3, Sheet 2, there are
two pairs of wheels marked 1, and 2; and 3, and 4, which convey motion from the
cone pulley g, to the second counter spindle d; the changeable wheels a, transmit the
driving motion from the second counter spindle d, to the first counter spindle c.
wheel 5, driven by the first counter spindle c, gears with the wheel 6, and actuates
the main spindle b. By connecting the barrel or sleeve e, with the coupling flanges f,
the lathe can be worked with the ordinary back gear wheels 1, and 2, and 5, and 6,
without the changeable wheels.
The
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed or carried into practical effect, I
declare that what I claim is
1. The construction and use of lathes and similar machines in which the ends of the
main and the counter spindles project or extend beyond their back bearings, and are
fitted with changeable wheels of varying diameters for the purpose of regulating the
speed and purchase of the lathe or other similar machine; substantially as hereinbefore
described, and as illustrated on Sheets 1, and 3, of the accompanying drawings, or any
equivalent modification thereof.
2. The construction and use of lathes and similar machines in which are two or
more counter spindles, placed and fixed in any convenient and suitable position, the
ends of which project or extend beyond either their back or their front bearings, and
are fitted with changeable wheels of varying diameters for the purpose of regulating
the speed and purchase of the lathe or other similar machine; substantially as here-
inbefore described, and as illustrated on Sheets 2, 4, 5, and 6, of the accompanying
drawings, or any equivalent modification thereof.
