page_text: LETTERS PATENT to John Wareing, of Salford, in the County of Lancaster,
Spindle Forger, for the Invention of "IMPROVEMENTS APPLICABLE TO
RYDER'S FORGING MACHINE, WHICH RENDER IT BETTER ADAPTED FOR FORGING
"
Sealed the 5th November 1861, and dated the. 11th May 1861.
PROVISIONAL SPECIFICATION left by the said John Wareing at the
Office of the Commissioners of Patents, with his Petition, on the 11th
May 1861.
I, JOHN WAREING, of Salford, in the County of Lancaster, Spindle Forger,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
APPLICABLE TO RYDER'S FORGING MACHINE, WHICH RENDER IT BETTER ADAPTED FOR
FORGING MULE SPINDLES AND ARTICLES OF SIMILAR FORM," to be as follows:-.
My improvements in Ryder's forging machine have for their object the
removal of its imperfections in the drawing or reducing of rods or bars of
metal into long taper articles like mule spindles. This has been hitherto dono
in Ryder's forging machine by broad hammers or swages formed into two
separate flat inclined faces, one pair of faces being intended for the smallest
part of the taper, and the other for the largest part of the taper, so that the
entire length of the taper has to be drawn at two operations, the faces of the
swages covering about half the length of the taper at each operation, which
consists in forcing the rod or bar (rotating it at the same time) endwards
between the inclined faces of the swages. The defect of this mode of action
is that the rod or bar when reduced small is liable to split in the operation,
owing to the absence of a true "drawing action" in the ordinary hammers or
swages.

page_text: My Invention relates to an improved mode and arrangements for producing
a true drawing action, by which the defect above mentioned is obviated, and
it consists in making the acting faces of the swages or hammers narrow in the
<lirection of the length, but broad or long in the direction across the rod or
bar operated upon and in forming and arranging them, so that the space
between the two faces at one side will be wide enough to admit the largest
part of the intended taper to be formed, the space gradually diminishing to
the other side where the space between the faces is only sufficient to admit the
smallest part of the intended taper. The rod or bar to be reduced is entered
between the swaging or drawing edges on that side of them where the space
is the widest, and it is pushed through to the greatest length the rod is intended
to be operated upon, and is then traversed (in a direction at a right angle to
its length) across the swages to the narrowest space between them, and is
simultaneously rotated and withdrawn in the direction of its length, so that
when it has traversed across, its point end will be in the narrowest space
between the swages. This withdrawing movement is made simultaneous
with the movement traversing across by means of a guide placed in an inclined
position in relation to the swaging or reducing edges, which guide forces the
point end of the rod or bar backwards as it is traversed across the swages, the
end of the rod or bar being pushed against the inclined guide when entered
between the swages, which thus serves as a stop to determine the length of
the rod or bar to be operated upon. I believe this inclined guide to be the
simplest, but other arrangements may be substituted for it.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Wareing in the Great Seal Patent Office, on 2
the 8th November 1861.

One thousand eight hundred and sixty-one, in the twenty-fourth year of

me, the said John Wareing, Her special license that I, the said John
Wareing, my executors, administrators, and assigns, or such others as I, 3
the said John Wareing, my executors, administrators, and assigns, should

page_text: 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 APPLICABLE TO RYDER'S FORGING MACHINE, WHICH RENDER IT BETTER
ADAPTED FOR FORGING MULE SPINDLES AND ARTICLES OF SIMILAR FORM," upon
the condition (amongst others) that I, the said John Wareing, by an instru-
ment in writing under my hand and seal, 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 John Wareing, do hereby declaré
the nature of my said Invention, and in what manner the same is to be per-.
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings (that is to say) :-
:-
My improvements in Ryder's forging machine have for their object. tho
removal of its imperfections in the drawing or reducing of rods or bars of
metal into long taper articles like mule spindles. This has been generally
done hitherto in Ryder's forging machine by broad hammers or swages formed
into two separate flat inclined faces, one part being intended for the smallest
and the other for the largest part of the taper, so that the entire length of the
taper has to be drawn at two opérations, the faces of the swagės covering.
about half the length of the taper at each operation, which consists in forcing
the rod or bar (rotating it at the same time) endways between the inclined
faces of the swages. The defect of this mode of action is that the rod or bar
when reduced small is liable to split in the operation owing to its rapid cooling.
and the absence of a true "drawing action" in the ordinary hammers or:
swages.
My Invention relates to an improved mode and arrangements for producing
a true drawing action, by which the defect above mentioned is obviated, and
it consists in making the acting faces of the swagės or hammers narrow in the
direction of the length, but broad or long in the direction across the rod or
bar operated upon, and in forming and arranging them so that the space
between the two faces at one side will be wide enough to admit the largest
part of the intended taper, the space gradually diminishing to the other side
where the space between the faces is only sufficient to admit the smallest part
of the intended taper. In practice I have discovered that the best mode of
action is to enter the point end of the rod on bar between the swages or drawing

page_text: edges on the side where the space between them is the narrowest, then to
traverse the rod or bar across the swages to the widest part of them, and then
back again to the narrowest part. When the rod or bar is traversed across it
is simultaneously rotated and pushed through the swages or drawing edges, so
that when at the widest part of them it is pushed to its greatest length through
the swages or drawing edges, and when traversed back again it is simulta-
neously rotated and withdrawn till the point end is between the narrowest part
between the swages or drawing edges. This inserting and withdrawing move-
ment is made simultaneous with the movement traversing across by means of
a guide placed in an inclined position in relation to the swages or drawing
edges, which guide prevents the point end of the rod from being pushed too
far through the swages or drawing edges when traversed in one direction, and
forces it back again when traversed in the other direction. The guide thus
serves a "stop," to determine what part of the length of the taper from the
point each part of the swages or drawing edges are to operate upon.
Fig. 1 of the accompanying Drawing is a front view of part of the swages
or drawing edges; Fig. 2 is a plan view. a, swages or drawing edges; b,
inclined guide, secured to carrier c. The rod or bar operated upon is repre-
sented in dotted line by d. It is first entered at 1, and then traversed across
to 2, and then back to 1, the axis of the rod being kept perpendicular to the
dotted line 1, 2, on Fig. 2, and the point end against the inclined guide b.
When the rod or bar has been reduced it is passed between swages to
straighten it, and is afterwards made round and smooth by the ordinary swages.
I have now particularly described and ascertained the nature of my said
Invention, and the mode in which the same may to be carried into effect, and
claim as my Invention the forging of mule spindles, and other articles of
similar form in Ryder's forging machine by the combination of the hammers,
swages, or drawing edges and the inclined guide, substantially as herein-before
described.
In witness whereof, I, the said John Wareing, have hereunto set my
hand and seal, this Seventh day of November, in the year of our
Lord One thousand eight hundred and sixty-one.
JOHN WAREING. (L.S.)
