page_text: LETTERS PATENT- to James. Dodge, of Manchester, in the County of
Lancaster, Mechanical Engineer, for the Invention of "IMPROVEMENTS IN
APPARATUS FOR ROLLING, SHAPING, AND FORGING FILE-BLANKS,' 'FLYERS,'
AND OTHER METALLIC ARTICLES OF SMALL DIMENSIONS."
Sealed the 13th June 1865, and dated the 28th December 1864.
PROVISIONAL SPECIFICATION left by the said James Dodge at the
Office of the Commissioners of Patents, with his Petition, on the 28th
December 1864.
"I, JAMES DODGE, of Manchester, in the County of Lancaster, Mechanical
Engineer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN APPARATUS FOR ROLLING, SHAPING, AND FORGING 'FILE-BLANKS,'
"FLYERS, AND OTHER METALLIC ARTICLES OF SMALL DIMENSIONS," to be as
follows:-
The Invention' relates to a novel construction of self-acting mechanism for
rolling and forging small articles of metal, so arranged that the various
operations may be effected in one machine.
The improvements consist in the combination and use of a pair of rollers
with dies or matrices when required (for rolling the metal) and a pair of
"jaws" or levers for forging. The lower roller is furnished with tappets or
lifters which act upon the moveable lever or "jaw" of the pair of "jaws"
for forging or pressing the metal, the whole being operated by gearing. The
power is communicated to the rolls by means of a clutch box having steel-
faced clutches, and worked by levers actuated by a treddle. The upper roller
is furnished with a "swell" or cam which at a certain part of the revolution

page_text: lifts a bolt that raises the clutch-box lever, and throws the clutch out of gear,
and simultaneously a projection on the same roller comes into contact with a
short arm or "stop," and effects the instantaneous stoppage of the rollers;
this takes place at every entire revolution of the rollers, so that the attendant
has sufficient time to adjust the metal and to place it properly under the
rollers or jaws. The operator places his foot on the treddle, and withdraws
the short arm and bolt; the latter releases a spring which forces the clutch
box into gear, and starts the machine.
The second part of my Invention relates to a novel method of regulating
the distance between the rollers, and consists in the use of two wedges which
are inserted in the pedestals above the bearings of the top roller, and are
moved nearer to or further from each other by a right and left-handed screw,
which is provided with a collar, and it is held by snugs in a central block; by
turning this screw the. wedges are moved, and increase or decrease the dis-
tance between the rolls. The steps of the top roller are held up so as to
bear against the wedges by means of springs inserted between the steps of the
rollers.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Dodge in the Great Seal Patent Office on the
28th June 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
DODGE, of Manchester, in the County of Lancaster, Mechanical Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of December, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said James Dodge, Her special license that I, the said James Dodge, my
executors, administrators, and assigns, or such others as I, the said James
Dodge, 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, nse, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel Islands
and Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS FOR ROLLING,
SHAPING, AND FORGING FILE-BLANKS,' 'FLYERS," AND OTHER METALLIC ARTICLES
OF SMALL DIMENSIONS," upon the condition (amongst others) that I, the said

page_text: James Dodge, 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 James Dodge, do hereby declare the
nature of the 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):-
.
The Invention relates to a novel construction of self-acting mechanism for
rolling and forging small articles of metal, so arranged that the various
operations may be effected in one machine.
The improvements consist in the combination and use of a pair of rollers
with dies or matrices when required (for rolling the metal), and a pair of
jaws or levers for forging; the lower roller is furnished with tappets or lifters,
which act upon the moveable lever or "jaw" of the pair of "jaws" for forging
or pressing the metal, the whole being operated by gearing; the power is
communicated to the rolls by means of a clutch box, having steel-faced clutches
and worked by levers actuated by a treadle. The upper roller is furnished
with a "swell" or cam, which at a certain part of the revolution lifts a bolt
that raises the clutch box lever, and throws the clutch out of gear, and
simultaneously a projection on the same roller comes into contact with a short
arm or "stop," and effects the instantaneous stoppage of the rollers; this
takes place at every entire revolution of the rollers, so that the attendant has
sufficient time to adjust the metal and to place it properly under. the rollers
or jaws. The operator places his foot on the treadle and withdraws the short
arm and bolt, the latter releases a spring, which forces the clutch box into
gear and starts the machine.
The second part of my Invention relates to a novel method of regulating
the distance between the rollers, and consists in the use of two wedges, which
are inserted in the pedestals above the bearings of the top roller, and are moved
nearer to or further from each other by a right and left-handed screw, which
is provided with a collar that is held by snugs in a central block; by turning
this screw the wedges are moved, and increase or decrease the distance between
the rolls. The steps of the top roller are held up so as to bear against the
wedges by means of springs inserted between the steps of the rollers.
In order that the Invention may be better understood and explained in
detail, I have hereunto attached a Sheet of Drawings made upon a scale of

page_text: about three inches to the foot, similar letters of reference being marked
upon corresponding parts on all the Figures.
Fig. 1 represents an elevation viewed from the left-hand side of the
rolling machine, shewing the peculiar arrangement and construction of the
apparatus in connection with the clutch box for starting and stopping such s
machine.
Fig. 2 represents a front elevation of the apparatus, 'shewing more
particularly the position of the rollers with dies or matrices formed therein for
rolling the metal; and the pair of jaws or levers, also supplied with dies or
matrices for forging.
:
Fig. 3 represents an elevation viewed from the right-hand side of the
machine, illustrating more clearly the jaws or levers for forging; and also the
arrangement of mechanism for actuating the same.
And Fig. 4 represents an arrangement of tappets for actuating the under
"jaw in place of the eccentrics.
.
In Figs. 1, 2, 3, and 4, a, a, is the framing of the machine supporting the
rollers 6 and 6'; the top roller 6' is capable of being raised from or lowered
nearer to the bottom roller 6 (according to the thickness of metal required to
be operated upon) by the wedges c, c, and springs d, d, which being inserted
between the bearings of the two rollers, has a tendency to raise the top
roller 6', the distance between such rollers being regulated by the counter
action of the wedges c, c, which are moved nearer to or further from each other
by a right and left-handed screw e, which is provided with a collar f, which is
held by the "snugs" g, g, in a central block, so that by turning the screws e,
the wedges are moved, and increase or decrease the distance between the
rollers. The top roller bis furnished with a swell or cäm h, which at a
certain part of the revolution lifts the bolt i, which raises the lever k in con-
nection therewith, and actuates the clutch box l, which is furnished with steel
clutches, thereby throwing such steel clutch out of gear; simultaneously, the
projection m on the roller b¹ comes into contact with the short arm or "stop" n
secured on the bell-crank lever o, and thus effects the instantaneous stoppage
of the rollers 6 and 6', which stoppage is effected at every entire revolution of
the rollers, thereby giving the attendant sufficient time to adjust the metal to
be operated upon under the rollers or jaws, and it will be evident that by
a'dding "lifts" or cams," the rollers may be stopped more frequently than
"
once every revolution. When ready to start the operator places his foot
on the treadle p, which immediately withdraws the short arm or "stop" n
and the bolt i; the latter releases the spring q, which forces (through the
medium of the lever k,) the clutch box into gear, and starts the machine.
.

page_text: The movement or action of the under lever or jaw employed for forging
"blanks" in conjunction with the fixed top jaws s, is obtained by means of
the eccentric t secured on the pinion or driving shaft u, seen in Fig. 1; the
rollers 6 and 6', and the pair of jaws r and are provided with dies or matrices
to suit the different form and shape of the "file blanks," or other metallic
articles required.
The grooves 1, 2, and 3 in the rollers and the recesses in the jaws exhibit
the form of matrices employed for rolling and forging round, half round, and
angular file blanks, and are shewn as examples. The movement of this lower
jaw may also be effected by means of a cam or tappets if preferred, as seen in
Fig. 4.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, I wish it to be distinctly
understood that I claim,-
First, the novel combination and use of one or more pairs of jaws or levers
containing dies and matrices, in conjunction with rollers for rolling and forging
"file blanks" of any desired form, flyers, and other metallic articles.
Secondly, I claim the application and use in rolling machines of a metallic
clutch box, having steel faces or clutches which forms a durable and economical
clutch box.
Thirdly, I claim governing the rotation of the rollers and movement of the
jaws, so as to stop and start such rotation and movement at any desired time
or position by means of the apparatus described, or by other mechanical
equivalents.
Fourthly, I claim the combination and use of the wedges and springs, as
described for regulating the distance of the rollers.
And, lastly, I claim the general construction, arrangement, and combination
of the apparatus for rolling, shaping, and forging "file blanks," "flyers," and
other metallic articles of small dimensions, as herein-before described, set
forth, and fully illustrated in the Drawings attached.
In witness whereof, I, the said James Dodge, have hereunto set my
hand and seal, this Twenty-third day of June, in the year of our
Lord One thousand eight hundred and sixty-five.
JAMES DODGE. (L.S.)
