LETTERS PATENT to James Russell, of Motherwell, in the County of
Lanark, North Britain, Engineer and Boiler Maker, for the Invention of
"IMPROVEMENTS I APPARATUS FOR DIMMING, WIDENING, OR FAIRING RIVER
HOLES."
Sealed the 7th February 1865, and dated the 11th August 1864.
PROVISIONAL SPECIFICATION left by the said James Russell at the
Office of the Commissioners of Patents, with his Petition, on the 11th
August 1864.
I, JAMES RUSSELL, of Motherwell, in the County of Lanark, North
Britain, Engineer and Boiler Maker, do hereby declare the nature of the
said Invention of "IMPROVEMENTS IN APPARATUS FOR RIMMING, WIDENING, OR
FAIRING RIVET HOLES," to be as follows, that is to say :-
This Invention has. for object the rimming, widening, or fairing of rivet
holes in plates or other parts for boilers and other structures in an expeditious,
superior, and accurate mauner. The operation is commonly performed by
means of a hand tool in a comparatively unsatisfactory manner, but by the
present Invention the tool, which may be of any of the kinds in use for
rimming, widening, or fairing holes by a rotatory movement, is carried by a
spindle mounted horizontally in bearings in a machine framing, and driven by

page_text: gearing from any convenient prime mover. The tool with its driving gear
and framing may constitute a separate machine, or it may be conveniently
combined with punching or rivetting details of any of the kinds in use that
are driven by means of rotating shafting, and two or more rimming tools may
be carried in the same machine. The tool may be held so as not to move
longitudinally, in which case the plate or article to be operated upon is
gradually pressed up to it as the widening or rimming proceeds; or the plate
or article to be operated upon may be held stationary, and the tool be pressed
towards it by a lever, a screw, or other equivalent detail.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Russell in the Great Seal Patent Office on the
10th February 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
RUSSELL, of Motherwell, in the County of Lanark, North Britain, Engineer
and Boiler Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of August, 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 Russell, Her special licence that I, the said James Russell,
my executors, administrators, and assigns, or such others as I, the said James
Russell, 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,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN APPARATUS FOR RIMMING, WIDENING, OR FAIRING RIVET HOLES," upon
the condition (amongst others) that I, the said James Russell, 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 Russell, do hereby declare
the nature of my said Invention, and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the following
statement in writing, reference being had to the accompanying Drawings, and
to the letters and figures marked thereon, that is to say :-
My said Invention has for object the rimming, widening, or fairing of rivet
holes in plates or other parts for boilers and other structures in an expeditious,
superior, and accurate manner. The operation is commonly performed by
means of a hand tool in a comparatively unsatisfactory manner, but by my
present Invention the tool, which may be of any of the kinds in use for
rimming, widening, or fairing holes by a rotatory movement, is carried by a
spindle mounted horizontally in bearings in a machine framing, and driven by
gearing from any convenient prime mover. The tool with its driving gear and
framing may constitute a separate machine, or it may be conveniently com-
bined with punching or rivetting details of the kinds in use that are driven by
means of rotatory shafting or otherwise, and two or more rimming tools may
be carried in the same machine.
And in order that my said Invention and the manner of performing the
same may be properly understood, I have hereunto appended a Sheet of
explanatory Drawings, to be herein-after referred to, and representing a
combined rivetting and rimming machine.
Figures 1 and 2 are elevations at right angles to each other. The machine
comprises a massive main standard 1, fitted with a short crank shaft 2 for
working the rivetting ram 3; and cast in one piece with a second massive
standard 4, which carries the opposing die 5. The machine is self-contained,
or complete in itself, the framing being cast with provision for the attachment
of a steam engine cylinder 6, which drives a shaft 7, having on it a pinion in
gear with a spur wheel on a second shaft 8. A pinion on this shaft 8, and
which can be put into or out of gear with it by means of a lever and clutch 9,
gears with and drives a spur wheel 10 on the rivetting shaft 2. The spur
wheel on the shaft 8 drives a pinion on a horizontal shaft 11, which by means
of bevil wheels gives motion to a vertical shaft 12, and this by means of
another pair of bevil wheels gives motion to the horizontal rimming
shaft 13. The rimming tool 14, which in the example represented is
a very slightly tapered spindle with three grooves cut longitudinally
upon it, is held in a socket in the end of the shaft 13. This shaft 18
is arranged to move longitudinally through the boss of the bevil wheel 15,
which drives it, a key and groove communicating rotation to it, and it
is formed with collars 16, so that it can be moved longitudinally whilst
rotating by means of a forked lever 17. In using the machine the boiler
shell or like structure in course of being put together and suspended from

page_text: a crane in the usual way is placed with the part to be rivetted between the
standards 1 and 4, and the holes being in succession brought opposite to
the tool 14 whilst it is rotating, it is worked into them by means of the
lever 17. A course of holes, being prepared or rimmed in this way may be at
once rivetted, and then the next course may be rimmed and rivetted. The
standard prevents the boiler shell from moving away from the tool, but a
bracket reaching up to the level of the tool may be fitted to it to hold against
articles which do not reach down to the standard 4. Instead of the tool 14
being moved longitudinally it may be stationary, whilst the article which is
being operated upon is moved up to it. When the rimming details are com-
bined with rivetting or punching details not driven by rotatory shafting, they
may be driven by special gearing from external shafting or from a donkey
engine.
Having now particularly described my said Invention, and the manner in
which it is or may be performed, I have to state that I do not restrict
myself to the precise details herein described or delineated; but that what I
believe to be novel and original, and claim as the Invention secured to me by
the herein-before in part recited Letters Patent, is, the arranging of tools
for rimming, widening, or fairing rivet holes in connection with driving gear
for working the same, substantially as herein-before described.
In witness whereof, I, the said James Russell, have hereunto set my hand
and seal, this Ninth day of February, in the year of our Lord One
thousand eight hundred and sixty-five.

Patent Agent,
