Year: 1861

page_text: LETTERS PATENT to William Ryder, of Bolton-le-Moors, in the County
of Lancaster, Roller and Spindle Maker, and Thomas Ryder, of the
same Place, Foreman, for the Invention of "IMPROVEMENTS IN MACHINES
AND DAD SHADING METALO"
PROVISIONAL SPECIFICATION left by the said William Ryder and
Thomas Ryder at the Office of the Commissioners of Patents, with
their Petition, on the 20th April 1861.
We, WILLIAM RYDER, of Bolton-le-Moors, in the County of Lancaster,
Roller and Spindle Maker, aud THOMAS RYDER, of the same Place, Foreman,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINES FOR FLUTING ROLLERS, AND FOR SHAPING METALS," to be as follows:-
Our improvements in machines for fluting rollers consists, first, in the
application of a worm and worm wheel for driving the link motion, by which
the table or carriage supporting the rollers to be fluted is moved to and fro
under the cutters, or by which the slide with the cutters is moved to and fro
over the rollers; the worm and
wheel combined with the link
motion are also applicable for moving the tool slide of shaping machines.
The second part of our Invention consists, in an improved mode of
constructing the brackets for holding the rollers to be fluted on the table

page_text: or carriage, the object being to economise space; the ends of the rollers
are supported in dies which fit between uprights cast to the headstock or
bearing.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Ryder and Thomas Ryder in the Great Seal
Patent Office on the 18th October 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
RYDER, of Bolton-le-Moors, in the County of Lancaster, Roller and Spindle
Maker, and THOMAS RYDER, of the same Place, Foreman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of April, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said William Ryder and Thomas Ryder, Her special licence
that we, the said William Ryder and Thomas Ryder, our executors,
administrators, and assigns, or such others as we, the said William Ryder and
Thomas Ryder, our 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,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
MACHINES FOR FLUTING ROLLERS, AND FOR SHAPING METALS," upon the condition
(amongst others) that we, the said William Ryder and Thomas Ryder,
our executors or administrators, by an instrument in writing under our, or
their, or one of our or their bands 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 we, the said William Ryder and Thomas Ryder,
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 (that is to say) :-
-
Our improvements in machines for fluting rollers consist, first, in the
application of a worm and worm wheel for driving the link motion by
which the table or carriage supporting the rollers to be fluted is moved

page_text: to and fro under the cutters, or by which the slide with the cutters is moved;
to and fro over the rollers; the worm and worm wheel combined with
the link motion are also applicable for moving the tool slide of shaping
machines.
The second part of our Invention consists, in an improved mode of
constructing the brackets and dies for holding the rollers to be fluted on the;
table or carriage.
And in order that our Invention may be fully understood and readily
carried into effect, we will proceed to describe the accompanying Sheet of
Drawings, reference being had to the figures and letters marked thereon.
Figure 1 is a side elevation of a machine for fluting rollers to which.
our improvements are applied, and Figure 2 is an end elevation of the same.
In those views a, a', are the side frames; b, the bed plate; c, the table or
carriage; and d, the cutters, which are or may be constructed in the usual.
manner; e is a horizontal shaft, to which motion is given by a driving strap
passing around the pulley e', to this shaft is fixed the worm gearing into
the worm wheel f which is fixed to a short shaft f revolving in a bush
fixed or cast to one of the frame sides; on the face of the worm wheel fis
the slot leverf in which is the adjustable stud f³ fitting into the slot lever g,
whose fulcrum is at g'; near the top of the lever g is jointed one end of
the link or connecting rod h, the other end of which is jointed to the table
or carriage c, consequently when the worm wheel revolves, the table or
carriage is moved to and fro on the bed plate 6, the amount of traverse being
varied according to the distance of the stud f³ from the centre of the wheel f.
This improved mode of giving motion to the table or carriage is also appli-
cable for giving motion to the slide with the cutters, and it combines great
power within a small compass. The worm and worm wheel combined with
the link motion, in the manner above described and shewn in the Drawing, is
also applicable for moving the tool slide of shaping machines.
Figure 3 is an elevation; Figure 4 a plan, and Figure 5 an edge view
of our improved brackets and dies for holding the rollers to be fluted; i is
a plate, shewn also in Figures 1 and 2, to which the two rows of brackets j
are cast, between the brackets are supported the dies k, the level of each
being regulated by the set screws 1; the end of each roller to be fluted is
supported in one of the dies k, as shewn in Figure 3, and the rollers are
held in the dies by the clips m. In constructing these improved brackets
and dies, the plate i is secured to the bed of a planing machine, and each
side of each bracket j, and the spaces between them, are planed out accurately,
the grooves of the dies & fitting the brackets j, and the other parts of the dies

page_text: are also planed out on a planing or shaping machine, by this means the
construction is simplified and the labor diminished.
Having thus stated the nature of our Invention and described the manner
of performing the same, we declare that we claim,―
First, the application of a worm and worm wheel in combination with
a link motion for giving motion to the table or carriage, or to the tool
slide of a machine for fluting rollers, as shewn and described in reference to
Figures 1 and 2.
Secondly, the improved arrangement of a worm and worm wheel combined
with a link motion for giving motion to the tool slide of a shaping machine,
as shewn and described.
And, lastly, the improved mode of constructing the brackets and dies for
supporting the rollers to be fluted, as shewn and described in reference to
Figures 3, 4, and 5.
In witness whereof, we, the said William Ryder and Thomas Ryder,
have hereunto set our hands and seals, this Seventeenth day of
October, in the year of our Lord One thousand eight hundred and
sixty-one.
