MACHINE FOR SOLDERING THE ENDS OF PROVISION TINS," A communication

PROVISIONAL SPECIFICATION left by the said Alexander Melville Clark at

ALEXANDER MELVILLE CLARK, of 53, Chancery Lane, in the County of Middle-
sex, Patent Agent. AN IMPROVED MACHINE FOR SOLDERING THE ENDS OF Pro-
VISION TINS.'
"
The object of this Invention is to furnish an improved machine for soldering the
ends upon tins or cans for containing provisions rapidly and thoroughly, and which
shall be simple in construction and convenient in use.
The Invention consists of a platform, track, or way, along which the cans are to
be rolled. The track is flanged along its side edges to keep the cans in place upon
it, and has a side inclination to cause the ends of said cans to rest upon the lower
side flange as they are rolled along said track. The track is slotted in the lower
side of its middle part along the flange to allow the end seam of the cans to project
through into a solder bath placed beneath it, and in which the solder is kept
melted by a furnace or other convenient means. The bath should be of such a
length that the cans may make at least one entire revolution with their end seams
in the solder, so that all parts of the said seams may be brought in contact with the
solder. The track is made with an upward incline at one end, down which the cans
are rolled in passing from the machine. The cans are rolled along the track by an
endless band, which passes around pulleys pivoted to the frame, and to one of which
motion may be given by hand power or by other convenient power. The band may
pass above the cans or below them, as may be most convenient, and should bear
upon them with sufficient force to convey them along the track with a steady and
uniform motion.

ALEXANDER MELVILLE CLARK, of 53, Chancery Lane, in the County of Middle-
sex, Patent Agent. "AN IMPROVED MACHINE FOR SOLDERING THE ENDS OF PRO-
VISION TINS." A communication from abroad by William Helme Ireland Howe,
of North Salem, County of Westchester, State of New York, United States of
America.
The object of this Invention is to furnish an improved machine for soldering the
ends upon cans or tins rapidly and thoroughly, and which shall be simple in con-
struction and convenient in use.
The Invention consists in the track made with a side inclination and a slot along
the lower side of its middle part, and provided with an endless belt, in combination
with a solder bath for soldering the end scams of cans, as herein-after fully
described.
In the Drawings Figure 1 is a front view of the improved machine; Figure 2 is
a cross section of the same taken through the line x,-x, Figure 1.
Similar letters of reference indicate corresponding parts.
A represents the frame of the machine, to which is attached a platform, track, or
way B, along which the cans C are to be rolled. The track B is flanged along its
side edges to keep the cans C in place upon it, and has a side inclination to cause
the ends of said cans to rest upon the lower side flange b₁ as they are rolled along
said track. The track B is slotted in the lower side of its middle part along the
flange b¹ to allow the end seam of the can C to project through into a solder
bath D placed beneath it in the frame A, and in which the solder is kept melted
by a furnace or other convenient means. The bath D should be of such a length
that the cans may make at least one entire revolution with their end seams in the
solder, so that all parts of the said seams may be brought in contact with the solder.
The track B is made with an incline at one end, see Figure 1, down which the cans
are rolled in passing from the machine. The cans C are rolled along the track B
by an endless band E, which passes around pulleys F pivoted to the frame A, and
to one of which motion may be given by hand power or by other convenient power.
The band E may pass above the cans, as shown in the Drawings, or below them, as
may be most convenient, and should bear upon them with sufficient force to convey
them along the track with a steady and uniform motion.
Having described the nature of the said Invention and the manner of performing
the same, I declare that what I claim as the Invention to be protected by the
herein-before in part recited Letters Patent is, the combination in a soldering
machine of the flanged, slotted, and inclined track B, endless band E, and solder
trough D, substantially as and for the purpose set forth.
In witness whereof, I, the said Alexander Melville Clark, have hereunto set
my hand and seal, this Twenty-fourth day of March, in the year of our Lord
One thousand eight hundred and seventy-seven.
