Henderson and John
NOW KNOW YE, that we, the said John, S
Macintosh, 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, reference being had to the

page_text: accompanying Drawings, and to the letters and figures marked thereon, that
iš to say:
Our said Invention, which relates to an improved mode of and an arrange-
ment of mechanism or apparatus to be used for soldering in or on the ends
of metallic cases or canisters and the body of the canisters themselves, is
based on another Invention for which Letters Patent were granted to us
bearing date the 11th day of July, 1867, 'and 'numbered 2033. Under the
present Invention after 'the 'cylindrical part of the canister is formed the
bottom is placed either on it or into it, and the cylinder together with the
bottom are placed upon a revolving platform or stand, which is put in
motion either by manual or other motive power. The parts to be soldered
have a ring of solder placed on or in them and a heated bolt or jet of
flame from a compound or other blow pipe is brought to bear on the solder
or part to be soldered; and the solder as soon as melted fills into the
spaces between the end or ends and body of the canister, and effectually
joins these parts. After the canisters are filled the cover is soldered to
the body of the canister in a similar manner.
And in order that our said Invention may be properly understood we now
proceed more particularly to set forth the system, mode, or inanner in or
under which the same is or may be used or practically carried into effect,
reference being had to the accompanying Drawings and to the letters and
figures marked thereon, that is to say:
Jo.
On these
Figure 1 is an elevation of the standard which the revolving platform
shown in section is fitted; Figure 2 is a plan of the platform.
Figures similar parts are indicated by similar letters of reference.
The socket A is jointed to the sole plate B, so that it may be tilted to any
convenient angle while the cases or canisters are being soldered. Into the
socket A a spindle C is fitted having à rope pulley D 'fitted on it, found
which a rope or cord E is wound, the end of which pass over the pulleys F, G,
which are attached to the bracket H, fitted on the socket A. To the end
of the cord E passing over the pulley 'G a weight W is attached, and the
end passing over the pulley
pulley is fastened to a treadle T, and by placing
the foot upon the treadle the spindle C to which the platform i is
is made to revolve so that while soldering on the ends of the canister K
the whole circumference of the joint is gradually brought into con
contact
with the blow pipe which is herein-after described. The platform I is or
may be constructed of steel wire or other metal not easily fused, and is
formed of arms L, fixed in and radiating from the spindle C, on the arnis L.
rings M of different sizes to suit the different sizes of canisters are fixed'

page_text: within which the canister to be soldered is placed, upright wires. N of any
convenient number slide vertically in the arms L, and are hooked at the
upper end in the manner shown in Figure 1 for the purpose of catching the
cases and holding them in position.
.
Figure 3 is a side elevation, and Figure 4 a plan of a compound blow
pipe, by which canisters formed by any of the modes for which Letters
Patent, bearing the date 11th day of July 1867, and numbered 2033, were
granted to us may be soldered. The compound blow pipe consists of a
tube A formed of copper or any other metal not easily fused, and which is
supplied by the tube B with coal or other gas which will combine with
atmospheric air supplied by the tube C, both tubes being supplied with stop
cocks to regulate the quantity of gas and atmosphere air passing through
the blow pipe, so as to give a heat intense enough to melt the solder. The
tube C by which the atmospheric air is supplied is screwed at the part where
it enters the tube A, so that the distance between the point of the tube A
and C, may be regulated as shown dotted on Figure 3, the jamb nut a
retaining them in the required position and preserving the joint air tight.
On Figure 3, a canister 6 is represented as being soldered after being formed
on the roller D; the flame is shown issuing from the blow pipe in a tapered
form produced by the taper of the tubes A and C, and impinging on the
solder on the joint of the canister, melts the same, which on cooling forms
the joint. The blow pipe is mounted on a stand E provided with a suitable
number of joints having straps c and pinching screws d to give facility in its
being turned to any required place or position, and there fixed so as to fit
any size of apparatus and admit of the blow pipe being brought' to bear at
any angle on the seam of the canister while on the forming roller or on the
platform herein-before described; one or more of these joints being provided
with a slot e and pin f to admit of the blow pipe being easy and accurately
turned from seam to seam at the angle desired. When soldering the case
on the forming roller D the stand E is mounted on a slide F, placed between
the guides G fixed on the sole plate H parallel to the roller D, and whilst
soldering the side seam the stand E is moved along between the guides G,
thus bringing the flame into contact with the solder along the joint. The
end may now be soldered on if wished by bringing the flame of the blow pipe
in contact with it and turning the roller D until the whole circumference of
the joint is formed. When soldering on the revolving platform I, Figure 1,
the canister is laid on the same with the end on or in and the flame of the
blow pipe brought into any of the positions shown dotted on Figure 1
according as the joint is to be formed outside or inside. The air from the

page_text: blow pipe may be supplied by a blast fan, or bellows, or by any other mode, and
the blow pipe instead of being mounted on a stand may be applied by hand. To
facilitate the application of the solder a pipe or passage leading in the direction
of the part to be soldered may be employed, and in this pipe or passage pieces
of solder are placed which when emerging by their own gravity are forced
out from the pipe or passage, and coming into contact with the flame from
the blow pipe are melted; or in place of this arrangement a wire or ribbon of
solder may be carried upon a drum, which being unwound by the rotation of
the drum is directed by a tube, passage, or other guide to the part about to
be soldered. In either case a stop is provided, or other means for retarding
or withdrawing the solder when requisite.
Having now described the nature of our said Invention and the manner in
which the same is or may be used or practically carried into effect, we would
observe in conclusion that we do not confine ourselves to the precise details
which we have herein-before set forth, but what we do consider as novel and
original and therefor claim as the Invention secured to us by the herein-before
in part recited Letters Patent is,―
First. The general mode of soldering cases or canisters by mechanism as
herein-before described or any mere modification thereof.
Second. The use of the revolving table to which the canister is fixed whilst
being soldered, and the combination therewith of one or more compound blow
pipes as herein-before described and shown in the accompanying Sheet of
Drawings or any mere modification thereof.
In witness whereof, we, the said John Sharp Henderson and John
Macintosh, have hereunto set our hands and seals, this Twenty-seventh
day of February, One thousand eight hundred and sixty-eight.
