Year: 1857

page_text: LETTERS PATENT to Stanley Webster, of Bolton-le-Moors, in the County
of Lancaster,. Foreman, for the Invention of "CERTAIN IMPROVEMENTS IN
MACHINERY OD ADDADAMING BAD TERNING"
Sealed the 23rd April 1858, and dated the 12th November 1857.
PROVISIONAL SPECIFICATION left by the said Stanley Webster at the
Office of the Commissioners of Patents, with his Petition, on the 12th
November 1857.
I, STANLEY WEBSTER, of Bolton-le-Moors, in the County of Lancaster,
Foreman, do hereby declare the nature of the said Invention for ." CERTAIN
IMPROVEMENTS IN MACHINERY OR APPARATUS FOR TURNING," to be as follows:-
The object of this Invention is to dispense with the arbors or mandrils upon
which articles to be turned are usually fixed. My Invention consists in fitting
one end of the article to be turned on to a centre stud, placed within a chuck
fixed to the driving spindle of the headstock; this chuck, when wheels are to be
turned, is provided with an internal wheel, corresponding with the wheel to be
turned; the teeth of this internal wheel fitting between the spaces of the teeth
of the wheel to be turned carry the wheel round. When bushes or other articles
without teeth are to be turned, they are held in the chuck by set screws or other
suitable fastening apparatus. The spindle of the loose headstock is provided

page_text: with a stud fitting into the other end of the article to be turned to keep it
true; by this improved arrangement the articles to be turned are securely held
in the lathe during the operation of turning, and the injury occasioned by
driving an arbor or mandril in and out is avoided; the articles when turned
are also more accurate, and a considerable saving in time is effected.
Another part of my Invention consists in an apparatus for turning articles
with a surface in a diagonal direction to the line of the axis; the apparatus
consists of a face plate fixed to the driving spindle of the lathe; this face plate
has a hemispherical boss, on which fits a disk with a corresponding hole; the
face plate and disk are connected by bolts; the article to be turned is fixed
to the disk, and the angle of the disk to the line of the axis is determined by
screwing up the connecting bolts.
My Invention also consists of an apparatus to facilitate the turning of
articles to one uniform length. To the driving spindle of the lathe is fixed a
centre or stud with a plate; this plate is fixed at the required distance from
the end of the centre, and the articles to be turned are put on the centre and
carried round by a stud projecting from the plate. When the article is on
the centre, the end thereof is turned away level with the end of the centre;
by this means any number of articles may be turned off to the same length.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Stanley Webster in the Great Seal Patent Office on the 5th
May 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, STANLEY
WEBSTER, of Bolton-le-Moors, in the County of Lancaster, Foreman, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of November, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Stanley Webster Her special licence that I, the said Stanley Webster,
my executors, administrators, and assigns, or such others as I, the said
Stanley Webster, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,

page_text: exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "CERTAIN IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR TURNING," upon the condition (amongst
others) that I, the said Stanley Webster, my executors or administrators, by
an instrument in writing under my or their or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Stanley Webster, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement (that is to say):-
The nature of my said Invention consists, first, in an improved apparatus
for holding articles to be turned while in the lathe, by which apparatus the
arbors or mandrils usually employed are dispensed with; secondly, in an
improved apparatus to facilitate the turning of articles to one uniform length;
and, lastly, in an improved apparatus for turning articles with a surface in
a diagonal direction to the line of the axis.
Having thus stated the nature of my Invention, I will proceed to describe
how the same may be carried into effect, reference being had to the accom-
panying Sheet of Drawings and to the figures and letters marked thereon.
Fig. 1 represents an elevation of a lathe, to which the first part of my
Invention is applied; a, is the fast headstock, and b, the driving spindle
thereof; these parts and the loose headstock c are made in the usual manner.
To the spindle b is screwed the bush d and the centre stud e fits in the end
of the spindle; to the bush d is screwed the chuck f, the centre stud e
projects beyond the chuck f, which is made with internal teeth correspond-
ing to those in the wheel to be turned marked g. The part of the
centre stud e projecting beyond the chuck f is of the same diameter as the
hole in the wheel g; but there is a shoulder on the said stud, against which
the boss of the wheel to be turned fits; this shoulder prevents the teeth of the
wheel g becoming fast in the spaces between the teeth in the chuck f. When
the wheel g has been placed on the centre stud e, the centre stud h of the
loose headstock c is brought into the position shewn in Fig. 1, that is to say,
the end of the centre stud h just enters into the hole in the wheel g; by
this means, when motion is given to the driving spindle b, the bush and
chuck fare turned round, and as the teeth of the wheel genter in the spaces

page_text: between the teeth of the chuck f, it is evident that the wheel g is also carried
round while being turned; the arbors or mandrils usually employed are thus
dispensed with, and all the injury and loss of time occasioned by driving the
mandrils in and out of the articles to be turned are avoided. The chuck f
can easily be unscrewed out of the bush d and another put in its place to turn
wheels of other dimensions than that shewn in the Drawing. When bushes or
other articles without teeth are to be turned, they are held in the chuck by set
screws or other suitable fastening apparatus.
"
Fig. 2 is an elevation in section, and Fig. 3, a front view, of my improved
apparatus to facilitate the turning of articles to one uniform length. a is the
fast headstock, and 6 part of the driving spindle of a lathe; to. the spindle b is
screwed the bush i, and to this bush is screwed the plate j; the centre stud-k
fits in the end of the driving spindle b, and on this stud fits a bush 7 of the
exact length of the article to be turned; the plate is 'furnished with a screw
and nut, from which projects a stud to carry round the wheel g or other article
to be turned. When the bosses of a great number of wheels or other articles
have to be turned to the same uniform length, they are put upon the bush l, as
shewn in Fig. 2; the workman then applies the cutting tool to the end of the
boss, and turns it off until the boss comes fair with the end of the bush / which
is made by preference of hardened steel; a modification of this part of my
Invention may be made by having an adjustable plate on the centre stud k,
and fitting this plate at the required distance from the end of the stud, which
then serves as the measure for the length of the boss to be.turned.
Fig. 4 is a section and Fig. 5 a front view of an apparatus constructed for
turning surfaces in a diagonal direction; m is a face plate screwed to the
driving spindle of a lathe of the usual construction, the face of this plate is
provided with a hemispherical boss m', on which fits the disk n; the screw
bolts, o, o, connect the disk n to the plate m, and the article to be turned,
marked p, is secured to the disk n by the clamps q, q, or other convenient
The angle at which the disk n is set can be, varied by the screw
means.

Having thus described the nature of my Invention, and the manner of
performing the same, I declare that what I claim is,
First, the improved apparatus shewn and described in reference to Fig. 1
for holding articles to be turned while in the lathe, whereby the arbors or
mandrils usually employed are dispensed with.
Secondly, the improved apparatus shewn and described in reference to
Figs. 2 and 3, for turning articles to the same uniform length.

page_text: And, lastly, the improved apparatus shewn and described in reference to
Figs. 4 and 5, for turning articles with a surface in a diagonal direction to that
of the axis.
In witness whereof, I, the said Stanley Webster, have hereunto set my
hand and seal, this Twenty-ninth day of April, in the year of our
Lord One thousand eight hundred and fifty-eight.
