EMPLOYED IN CAPPING PRESERVING AND OTHER CANS OR TINS." A com-
munication from abroad by H. K. and F. B. Thurber and Company, of the

23, Southampton Buildings, in the County of Middlesex, Patent Agent.
"IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED IN CAPPING PRE-
SERVING AND OTHER CANS OR TINS." A communication from abroad by H. K.

The capping machine consists of a frame work in the form of two parallel
benches with a raised platform between, on which the boy who feeds to tho
solderer stands. On the outside edge of these benches is a series of spindles, on
the lower end of each of which is a small grooved pulley around which runs an
endless chain or band running over a cylinder under the platform. On the upper
end of each spindle and a few inches above the bench is an iron bowl having
grooves moulded in it preferably to receive two sizes of cans, say, for instance,
the standard two and three pound cans.
In cases where special sized cans are used, chucks to receive those sizes can be
furnished at a slight additional cost. Alongside the spindles and running through
the benches are a corresponding number of rods having each a weight at the lower
end, and the upper end being curved over in such a manner that, when pushed to
one side, the end of the curve fits in the centre of the cap on the can in the bowl,
and forms a pivot for the can to rotate on. When the cap is soldered this rod is
pulled up, pushed to one side, and rests in a small slotted upright placed there for
the purpose. The machine is simple in construction, and not liable to get out of
order.

BENJAMIN JOSEPH BARNARD MILLS, of the Firm of Harris and Mills, of

"IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED IN CAPPING PRE-
SERVING AND OTHER CANS OR TINS." A communication from abroad by H. K.
and F. B. Thurber and Company, of the City, County, and State of New York,
in the United States of America.
The capping machine consists of a frame-work in the form of two parallel
benches with a raised platform between, on which the boy who feeds to the solderer
stands. On the outside edge of these benches is a series of spindles, on the lower
end of each of which is a small grooved pulley around which runs an endless
chain or band running over a cylinder under the. platform. On the upper end of
each spindle and a few inches above the bench is an iron bowl having grooves
moulded in it preferably to receive two sizes of cans, say, for instance, the standard
two and three pound cans. In cases where special size cans are used, chucks to
receive those sizes can be furnished at a slight additional cost. Alongside the
spindles and running through the benches are a corresponding number of rods
having each a weight at the lower end, and the upper end being curved over in
such a manner that when pushed to one side the end of the curve fits in the centre
of the cap on the can in the bowl and forms a pivot for the can to rotate on.
When the cap is soldered this rod is pulled up to one side and rests on a small
slotted upright placed there for the purpose. The machine is simple in construction
and not liable to get out of order.
And in order that the said Invention may be more clearly understood and
readily carried into effect, I will proceed, aided by the accompanying Drawings,
more fully to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side view; Figure 2 is a plan; Figure 3 is an end view of
machinery or apparatus constructed according to the said Invention.
A-represents-the-stand-or-frame-which-consists-of-two parallel-benches. These
stands or benches are of sufficient width to afford room for a tray of containing
cans to be placed thercon, and are supported by posts or standards which rest on
a frame c placed on the floor. A number of vertical shafts or spindles B placed
at suitable distances apart rest in bearings a secured to the frame c, the upper
bearing of the shafts or spindles being in the outer rail A. Each shaft has secured
on its upper extremity a disc or bowl d having grooves moulded in it preferably to
receive two sizes of cans, which disc or bowl serves as a seat upon which to place
a can while its cap is being soldered.
e is an iron rod passing vertically through the stand or bench, and to the lower
end of which below the stand a weight fis attached. Toward the upper end this
rod is bent at a right angle to its vertical portion, and is provided at the end with
a knob g made of porcelain or some vitreous material which rests upon the cap
during the operation of soldering, and serves by means of the weight to hold the
cap down.
The knob may be made of any other material than that named, but it is desirable
that it be something to which the solder will not adhere.
An arm projects from the rod in line with the bent upper end, and rests on a
semicircular guide-way placed edgewise on the stand or bench. The upper edge
is provided with two slots K, and midway between these is a notch m in which
the armrests when the knob is on the cap. The rod e is adapted to be turned

page_text: by the hand to the right or left until the arm / falls into a slot , and has a
vertical sliding movement to permit the arm to drop in the notch or be raised out
of it.
A horizontal drum or cylinder L has its bearings in the frame c, and is placed
midway between the two series of vertical shafts or spindles with which it is
connected by belts or bands n of any suitable kind. This drum or cylinder L is of
uniform size and of length sufficient to connect with the entire series of vertical
shafts or spindles. It is driven by power applied to the pulley 7, and is covered
by a platform 8 onto which pass the attendants, who may be children, to place the
cans on the discs and remove them when soldered, while the operator with the
soldering iron takes position on the outside of the stand or bench.
It will be seen that when the can is on the disc or bowl, and the cap is held
down by the knob pressing on it, and the machine is in motion, the can is caused
to rotate, and the cap may be instantly soldered by the application of an iron at
one point.
The rods having the knob for holding down the cap or the head, as the case
may be, are entirely out of the way of the operator, and are no impediment
whatever.
In the present instance there are fifteen shafts or spindles and can seats, discs,
or bowls shewn on each stand or bench, though a greater or less number may be
employed. Instead of two stands or benches, as shewn, and two series of shafts
or spindles with can seats, there may be but one.
The drum or cylinder L having a uniform size constitutes a continuous pulley
adapted to receive at any point the belts or bands which drive the vertical shafts
or spindles, and is much cheaper than a shaft provided with a number of pulleys,
and, unlike the latter, does not require any adjustment to suit the belts or bands.
The location also of the horizontal drum or cylinder permits of the platform being
placed over it, rendering both sides of the machine accessible for the attendants,
and all the operative parts are out of the way.
Having thus described the nature of the said Invention, and the mode in which
the same may be carried into effect, I would have it understood that what I claim
is,-
First. In combination with a can seat disc or bowl made to receive one or
more sizes, a rod adapted to have a partial rotary and a vertical sliding movement;
as described, and having one end adapted to rest on the can cap or head, and the
other provided with a weight and having a projecting arm and a guideway for
the arm having stops and a notch, as set forth.
Second. In a can capping machine the combination of a vertical moveable
weighted rod having one end provided with a knob of porcelain or vitreous
material to rest on the can cap, a horizontally projecting arisattached rigidly to
the rod, and a semicircular guideway for the arm having stops, as set forth.
Third. In a can soldering machine the combination of the horizontal drum or
cylinder L having bearings in frame c, platform s, placed over the drum or cylinder,
a series of vertical shafts or spindles B, each provided with a can seat disc or
bowl d made to receive one or more sizes, and a rod passing vertically through the
stand or bench, and weighted and having its upper end bent to rest on the can
cap or head, as set forth."
In witness whereof, I, the said Benjamin Joseph Barnard Mills, have here-
unto set my hand and seal, this Second day of February, in the year
of our Lord One thousand eight hundred and eighty two.
