A NEW OR IMPROVED MACHINE TO BE EMPLOYED IN THE MANUFACTURE OF TIN AND OTHER METAL CANS AND CASES
Year: 1884

page_text: I JAMES MACONOCHIE of Lowestoft, Suffolk Preserved Provision Manufacturer
do hereby declare the nature of my invention for
"A NEW OR IMPROVED
MACHINE TO BE EMPLOYED IN THE MANUFACTURE OF TIN AND OTHER METAL
CANS AND CASES" to be as follows:-
The object of my invention is to greatly facilitate the manufacture of tin and
other metal cans and cases by a novel method of mechanically soldering on the
tops and bottoms of such articles whereby a considerable economy in tiine labor
and expense is effected and the aid of skilled labor is rendered unnecessary at
the same time that great neatness of finish combined with perfect security is
obtained.
To effect this I construct a machine which consists of two revolving discs
mounted on suitable bearings and actuated either by a hand or treadle motion or
power.
Fitted in the framework of the machine at the bottom is a well or pan beneath
which a gas burner or its equivalent is fitted.
Such well serves as a receptacle for the solder which when placed therein is
reduced to and kept in a molten condition by the heat generated by the gas flime
issuing from the gas burner when ignited or by other equivalent mean*.
The before mentioned discs are so constructed and arranged that they hold the
can or other article immediately over, and at a suitable distance above such well
in such a position that when the discs are set in motion the ends of the can or
other article revolve in the heated solder and the parts to be soldered together are
almost instantaneously united.
For the purpose of removing any superfluous metal from the can or other article
the machine is fitted with a pair of suitable scrapers so placed that the can or other
article passes between them in the course of its travel and is so cleansed from any
such superfluous metal.

CASES and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:—
The object of this invention is to greatly facilitate the manufacture of tin and
other metal cans and cases by a novel method of mechanically soldering on the
tops and bottoms of such articles whereby a considerable economy in time labor
and expense is effected and the aid of skilled labor is rendered unnecessary at
the same time that great neatness of finish combined with perfect security is
obtained.
To effect this I construct a machine which consists of two revolving discs
mounted in suitable bearings and actuated either by a hand or treadle motion, or
by power.
Titted in the framework-of-the-machine at the bottom is a well or pan beneath
which a gas burner and supply pipe or their equivalents are fitted or placed. Such
well serves to hold the solder which when placed therein is reduced to and kept in
a molten condition by the heat generated by the gas or other flaine.
The revolving discs are so constructed and arranged that they hold the can or
other article immediately over and at a suitable distance above such well in such a
position that when the discs are set in motion one end of the can or other article
revolves in the heated solder and the parts to be soldered together are almost
instantaneously united-Tho can is then taken out of the machine and reversed and
then replaced and the other end treated in a similar way.
For the purpose of removing any superflous metal from the can or other article
the machine is fitted with scrapers so placed that the can or other article in the
course of its travel passes between them and any such superfluous metal is
removed.
And in order that my said invention may be better understood and readily
carried into effect I will now proceed to describe the accompanying drawings.
Fig 1 shews a view in side elevation of the machine a, a are the two revolving
discs between which the can or other article is placed-The disc a is mounted in a
slide guide b and its position is regulated by means of an oval key b¹ (Figs 4 and 5)
60 as to hold one end of the can over the solder pan q-This pan is mounted in a
dome frame (r) which forms a furnace and is supported on standards (8) screwed
or bolted to a base plate (t)—Within such dome frame and beneath the pan a gas
burner and supply pipe-(not shown)-or their equivalents are fitted or placed as
already mentioned and a flue a is provided at the back of the dome or in any
other convenient position to permit of the escape of the smoke and other waste
products of combustion.
The disc a is affixed to one end of a spindle c which passes through a tubular
casing d and is screwed to or otherwise connected at its other end with a hand
wheele (or other suitable motor) and secured thereto by a nut f--This spindle
carries a movable collar f¹ and has a spiral spring f' mounted thereon within the
tubular casing d-This spring by its clip action serves to hold the can or other
article in position when placed between the revolving discs and so prevents its
falling through.
The tubular casing has a collar g fitted thereon at each end which form guides
for the spindle c to work in and by unscrewing these collars the adjustable

page_text: collar and coiled spring f" can be readily taken out and readjusted when
necessary-Such tubular casing d is mounted in a socket h wherein it is moved
forwards or backwards according to the length of the can or other article which
has to be held between the discs and is fixed in position by a set screw i-The
socket his connected by a universal joint j to an upright k also fixed by a set-
screw in a collar & furnished with a base plate m which is fastened by a set screw n
in a slotted guide plate o supported at its outer extremity by a standard and
foot p-p and having its other end secured to the dome top r-Holes are made
in the foot pl and base plate t to allow of the machine being screwed down to a
suitable bench or table.
A bracket (8) is fitted on each side of the solder pan each of which carries an
adjustable steel scraper (9) to remove any superfluous metal from tho cau or other
article as already mentioned.
Each scrapor is fixed in position by means of a set screw (7) fitting in the back
of each bracket.
Fig 2 shews a detail view of the spindle c adjustable collar f' and spiral springf
Fig 3 is a plan view of the slotted guide pinte o-Fig 4 shews a view in side
elevation of the disc a mounted in the slide of the slide guide & with the regulating
oval key b' fitted thereon and Fig 5 shews an independent view of such oval key
in front elevation,
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. A machine for mechanically soldering on the tops and bottoms of tin and
other metal cans and cases consisting of two adjustable revolving discs a-a' slide
guide b, oval key b', spindle c with movable collar f' and spiral spring f' tubular
casing d, with collars hand wheel e (or its equivalent) socket h, universal joint j
upright k, collar / base plate m, slotted guide plate o, standard and foot p p solder
pan q furnace r, Hue u standards a and base plate t all combined arranged and
titted substantially in the manner hereinbefore described and shewn.
Dated this 22nd day of August 1884.
