in the County of York, Boiler Makers, for the Invention of "IMPROVEMENTS
IN MACHINES FOR RIVETING BOILERS AND GIRDERS."

PROVISIONAL SPECIFICATION left by the said Israel Umpleby and Ben
Umpleby at the Office of the Commissioners of Patents on the 2nd April
1878.
ISRAEL UMPLEBY and BEN UMPLEBY, both of Cleckheaton, in the County of
York, Boiler Makers. "IMPROVEMENTS IN MACHINES FOR RIVETING BOILERS AND
GIRDERS."
The object of our Invention is to arrange an apparatus that can be applied to
the ordinary steam, hydraulic, or other riveting machines in such a manner that the
"Adamson's
apparatus will rivet the joints or seams of boiler flues, known as
rings;" also rivet the end plates to the shell angle iron of cylindrical or other
boilers, which are now riveted by hand, thus effecting a saving in labour.
We accomplish our object in the following manner :-We fix the casting or frame
of our apparatus to the pillar or dolly of the ordinary riveting machine. The end
of the ram from the cylinder of the riveting machine is brought in contact with a
lever that is centred in the casting or frame of our apparatus; the other end of
this lever is attached to the bottom slide of our apparatus. At the top of the
casting we fix another lever, which is connected by bars to the first-named
lever, and is attached to the top slides. These slides are fitted with adjustable cups
of the section required to form the heads of the rivets.
The boiler, flue, or other material that is being operated upon is swung in the
usual manner, and when the rivet in the joint or seam is brought between the
cups at the ends of the before-mentioned slides, and the piston of the machine is
put in motion, the ram will actuate the evers and slides before mentioned, and
press the rivet between the cups, and thus: vet the same quite tight.

GIRDERS."
"
The object of our Invention is to arrange an apparatus that can be applied to the
ordinary steam, hydraulic, eccentric, or other riveting machines now in common use
in such a manner that the apparatus will rivet the joints or seams of boiler flues
known as Adamson's rings," or other joints or scams in boilers, where the centre
line of the rivets is in the longitudinal direction of the boiler, such as riveting
the end plates to the shell angle iron rings of cylindrical or other boilers, which
are now riveted by hand; and thus, by the use of our apparatus, effect a saving
in time and labour.
We accomplish our object in the following manner:-We fix the casting forming
the frame of our apparatus to what is commonly known as the pillar or dolly of
the steam, hydraulic, eccentric, or other riveting machines now in common use.
The end of the ram, in connection with the ordinary riveting machines, brought
in contact with one end of a curved or angular lever that is mountod on a pin as
fulcrum, which passes through the casting forming the frame of our apparatus; the
other end of the said lever is in connection with a sliding block that is fitted into
a slide, which we call the bottom slide of our apparatus. At each side of the appa-
ratus we fix levers centred on the before-named pin; one end of the said levers we
attach to the before-named curved or angular lever. To the other ends of these
last-named levers we joint rods that are coupled to one end of another lever that is
mounted on a pin that passes through the frame at the top of our apparatus. The
other end of this last-named lever is in connection with another sliding block that
is fitted into a slide, which we call the top slide; these sliding blocks are fitted with
adjustable cups of the section required to form the heads of the rivets.
The boiler, flue, or other material that is being operated upon by the apparatus
is swung or suspended in the usual manner; and when the heated rivet is placed
in the seam or joint, and, the rivet brought between the cups that are fitted to the
ends of the top and bottom sliding blocks and the ordinary riveting machine, is put
in motion, the ram which moves in a horizontal direction presses against the
curved or angular lever, which moves on its fulcrum and rises the bottom sliding
block and cup attached thereto. At the same time motion is imparted from the
curved or angular lever through the side levers and connecting rods to the top
lever, which causes the top sliding block to descend towards the bottom sliding
block which is rising, and thus the rivet is pressed between the cups, and made
quite tight.
Such being the nature and object of this our Invention, we will now proceed to
describe the same in detail; and in order that the same may be fully understood
we have hereunto annexed one Sheet of Drawings, and have marked the same with
letters of reference.
Figure 1 represents the side elevation of our improved apparatus, which is fixed
to the ordinary pillar or dolly of a common horizontal riveting machine; Figure 2
is a front elevation of the same; and Figure 3, a back elevation.
In all the Figures similar letters represent similar parts.
To the ordinary pillar or dolly, which is indicated by the letter A, we secure a
strong metal clasp B, on the top of which we bolt our improved apparatus, the cast
frame of which is indicated by the letter C. At the back side of the apparatus,
and towards the bottom of the same, we mount a curved or angular lever D; this
lever is centred on the fulcrum pin E which passes through the frame A, and is
extended on each side thereof. To one end of lever D at F we secure pulley G, to

page_text: which reference will be horeafter made; the lover D is extended past the fulcrum
pin E to the front of the apparatus, where it is in connection with the bottom
sliding block H. At each side of the apparatus, on the extended portions of the
fulcrum pin E, we attach levers J, J; theso levers are attached to the lever D by
means of a pin passing through the same. At the other ends of levors J, J, are
jointed the connecting rods K, K, which are attached to ono end of top lever L that
is centred on pin M as fulcrum; the other end of lever L is in connection with the
top sliding block H¹. At the bottom of the top sliding block, and the top end of
the bottom sliding block, we secure cups N, N, of the required section to form tho
heads of the rivets.
It will be easily understood by practical boiler makers that when the ram O of
the ordinary riveting machine is put in motion, and moving horizontally in the
direction of the arrow, the end of the said ram will pass against the pulley G,
which will partly revolve, and the lever D will move on its fulcrum; and the other
end of the said lever, that is in connection with the bottom sliding block H, will
rise and lift the block, and at the same time the levors J, J, which are attached to
lever D, will actuate the lever L through the connecting rods K, K, and cause the
top sliding block H' to descend, and thus a vertical motion to the top and bottom
sliding blocks is obtained; and when the heated rivet in the material that is being
operated upon is placed between the cups N, N, and motion is applied to the
apparatus in the manner described, the top and bottom sliding blocks will press the
rivet between the cups, and make the same quite secure.
Having thus described our said Invention, and the manner in which the same
may be carried into effect, we would have it understood that we do not confine
ourselves to the precise details herein described and delineated, as the same may
be modified without departing from the characteristic nature of our Invention; but
that what we believe to be new and original, and claim as the Invention secured
to us by the herein-before in part recited Letters Patent is, the arrangement and
combination of the various parts of tho apparatus for transmitting a horizontal to a
vertical motion, and for actuating the top and bottom sliding blocks at the same
time, substantially for the purpose herein-before describod, and illustrated by the
accompanying Drawings.
In witness whereof, I, the said Israel Umpleby, for and on behalf of myself
and the said Ben Umpleby, have hereunto set my hand and scal, this
Thirtieth day of September, in the year of our Lord One thousand eight
hundred and seventy-eight.
