Improvements in Soldering Machines.
I, WILLIAM WOOLNOUGH of 174, Sebert Road, Forest Gate, Essex, Gentleman,
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements in machines for soldering the ends of
round vessels, such as tin boxes or cans, to their sides, and has for its chief object
to solder both ends simultaneously instead of one end only, during the passage of
the vessel through the machine as has hitherto been the practice. For this purpose
I provide receptacles upon each side of the pathway along which the vessels travel,
which receptacles contain in the first portion of their length the chemical soldering
liquid and in the latter portion the soldering metal, which is kept in a liquid or
melted state by means of a series of gas burners fitted beneath the said portion of
the receptacles.
"
The vessels are fed through the machine by means of a series of "bicycles" or
carriers fixed to a chain operated by two toothed wheels supported by the frame of
the machine above the receptacles, the said "bicycles or carriers being provided
with grooved rollers one of which travels along a rail between the receptacles and
the others hear upon the vessel to be soldered. The vessels pass between adjustable
guides fixed above the receptacles, and the latter are likewise adjustable by means
of a handscrew, according to the length of the vessel to be soldered.
Means are provided for automatically feeding each vessel to the "bicycles" of
carriers as the latter are brought into position for carrying the vessels through the
machine. The chemical soldering liquid is supplied to each receptacle by means
of a drop-cock and pipe from a tank fixed to the top of the frame, and the base of
the machine is formed of a trough shaped section to receive any overflowing of the
solder which may occur so as to prevent waste.
In the accompanying drawings Fig. 1 illustrates, in side elevation, my improved
machine, and Fig. 2 is a plan thereof, Fig. 3 is a front end elevation, Fig. 4 a cross
section to a larger scale of the solder receptacles and parts connected therewith,
Fig. 5 an end view of the mechanism for automatically feeding the vessels to the
bicycles or carriers, and Figs. 6 and 7 are two views of the latter, Fig. 8 being
a detail thereof.

a is the frame of the machine supported upon the trough shaped base a, b is the
driving shaft supported by the framing and carrying the fast and loose pulleys b' b².
Upon the shaft b is mounted a sprocket wheel c with which gears the endless
chain d which latter also gears with another sprocket wheel c' supported in slotted
extensions a² of the frame a, the chain being tightened or adjusted by the screw
bolts bearing against the bearing blocks c³. ee are two longitudinal frames
supported on the cross girders a³ of the frame a (see Fig. 3) and capable of adjust-
ment thereon by means of the right and left handed screw f working in extensions
or nuts e¹ secured to the flanges e² of the frames e.
The frames e are also provided with slotted extensions e³ to which are secured
by bolts g the adjustable guides g. and e are the receptacles, formed in the
frames e, for containing respectively the chemical soldering liquid and the soldering
metal, these receptacles being separated by a blank space e for preventing the
heat of the solder from affecting the chemical liquid. The solder is kept in a
melted condition by means of the gas burners which are preferably supplied
with air fed through an inner pipe ', shown clearly in the section Fig. 4, or
ordinary gas jets may be used, the supply pipes being passed through the holes /²
(Fig. 3). The chemical liquid is contained in a tank i supported on the top of

page_text: the frame a, and is continuously supplied to the receptacles e by means of the
drop cocks and pipes fixed to each side of the tank.
kis the series of "bicycles" or carriers fixed to the chain d for carrying the
vessels to be soldered through the machine, and which with the exception of one
of them are shown by a single dotted line in Fig. 1. These "bicycles" or carriers
are shown in Figs. 6 and 7 consist of an arm k provided with a grooved roller k¹
at its lower end, which roller travels along a guide rail l, fixed centrally between
the frames e, as the arm k pushes the vessels to be soldered along the said frames.
To each side of the arm k is secured a grooved roller 2 capable of adjustment
thereon by means of a thumb nut and slot as shown. Another arm k³ is pivoted to
the arm and provided with an adjustable roller k*.
The rollers and 4 bear against the vessel to be soldered as the latter is carried
through the machine, a spring keeping the roller in contact with the said
vessel. and are two arms adjustably connected to the arm k, and each formed
at one end with a projecting lip 48 (see Fig. 8) for the purpose of clearing the
inside upper edges of the receptacles e¹ and e' of any loose solder &c., which may
be left after the vessel has been soldered, so as to leave the said edges clean for
the passage of the next vessel. m m are inclined frames fixed to the frames e, for
receiving the vessels to be soldered and feeding them to the machine. These frames
are formed with slotted extensions m² for adjustably connecting the automatic
feeding device, shown in end view in Fig. 4, and which consists of two brackets n n
provided with lugs n' n¹ through which pass rods n² n* connected together at
their upper and lower ends by bars n³ n' to which are secured adjustable rods or
bars nn. Spiral springs n serve to keep the rods n² in their upward position.
The operation of the machine is as follows:-
The vessels o to be soldered are placed in line on the inclined frames m the
forward one resting against the bar n'. The receptacle frames e e are then adjusted
by means of the hand-screw so as to permit the ends of the vessel o to project
sufficiently over the inside edges of the said receptacle for the purpose of soldering
them.
The guides are also adjusted by the bolts g' to the length of the said vessels
and the machine is started.
The revolution the the chain d brings the roller k¹ of the foremost "bicycle" or
carrier k into contact with the upper bar n of the feeding device thus forcing
down the lower bar n and setting tree the foremost vessel, the upper bar n' being
at the same time brought down in front of the next succeeding vessel and stopping
it from following the first named one. The continued forward movement of the
carrier k causes it to take hold of, and push the liberated vessel along the upper
edge of the receptacles e¹ and e thus causing the ends, previously fitted on to the
sides to be soldered to the said sides. As the vessel arrives at the end of the
frames e it rolls down the incline plate p and is thus liberated from the carrier k.
As the roller k¹ is brought out of contact with the bar the springs n³ raise the
rod n² and with them the bars n thus permitting the next vessel to come into
contact with the latter bar ready for the next
6. bicycle or carrier to catch hold
"
of it.
Each succeeding "bicycle" or carrier operates in a similar manner to the one
already described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. In a soldering machine for simultaneously soldering both ends of a circular
vessel, the receptacles et e for containing the soldering material adjustable by
means of the screwed rod of substantially as described and shown in the drawings.
2. The combination with the above claimed receptacles of the burners /, the
adjustable guides g, and the inclined frames m substantially as and for the purpose
specified.

4. In a soldering machine as herein described, the automatic device for feeding
the vessels to be soldered to the machine substantially as described and shown in
the drawings.
5. In a soldering machine as herein described the " bicycles" or carriers con--
sisting of the slotted arms k k³ the grooved roller k', the adjustable rollers k³ k
