PROVISIONAL SPECIFICATION.
Improvements in Machines for Soldering Preserved Food Tins or
Cases.
I, JULES PLANÉS of Perigueux, Dorvogne, France, Merchant, do hereby
declare the nature of this invention to be as follows:-
This invention relates to machines for soldering the tins and cases used for
preserving food.
The machine is composed of a fixed circular plate or bed one part of which is
isolated from the other and this isolated part is heated by means of suitable gas
jets or a lamp. Immediately in front of the heated part is located an arch or cam
piece. Fixed on a vertical central revolving shaft is a narrow inner circular ring
made in one with a broad ring upon which are placed the objects to be soldered.
These rings are supported by a series of rollers which run on the fixed circular
plate aforesaid. The central shaft is revolved by means of gearing from a cross
shaft driven by hand or by power.
Fixed on the narrow ring aforesaid are a number of sockets or bushes in which
slide vertical rods having rollers at their lower ends which also run on the fixed
plate and as the machine.revolves they each, in their turn, mount up and descend
the cam or arch piece. Fitted in connection with these sliding rods are weighted
cups. The cups and rods can be regulated to any desired height.
The tins to be soldered are disposed to the left hand side of the cam and receive
the pressure weights as they pass in turn over the heated part of the device where
the soldering is done. The solder cools just at the right hand side of the cam.

1; JULES PLANES of Perigueux, Dorvogne, France, Merchant, 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 has specially for its object to construct a machine by which the
bottoms of metallic cases or tins can be soldered to the bodies without further
manual work than the mere placing of each case or tin upon one part of the
machine and then taking it up again after the actual work of soldering has been
performed by the machine itself.
My long experience and the following facts have led me to devise the present
machine. More than 20 years ago, when employed in one of the branch establish-
ments of Messrs. Peltier and Paillard at Perigueux, I soldered some tins by means
of a hot plate. The soldering was performed by holding the tin upon the hot plate

page_text: and when once the solder hardened sufficiently the tin was removed and placed
upon another plate to cool. The lid of the tin was first laid on the hot plate, and
then the body of the tin was carefully placed on the lid, finally a weight sufficiently
heavy to keep the two parts in contact was placed on top of the body. The weight
was allowed to remain during the cooling process. The work produced in this way
gave every satisfaction and since that date I have endeavoured to devise a machine
to do the soldering mechanically with a view as much to obtain great rapidity in
the production as to effect a desirable economy in an industry which requires
everything to be done as cheaply as possible in view of the very low selling price
of the finished articles.
The machine which I have devised for attaining the object herein before mentioned
is shown, by way of example, on the annexed sheet of drawings, whereon,
Fig. 1 is an elevation of the machine, with a part broken away in order to sbow
the cam or incline H.
Fig. 2 is a plan of the machine.
Fig. 3 shows, in section, a tin with its bottom ready to be soldered in place,
round the edge K.
The machine consists of a fixed circular plate or bed A which is made of any
suitable metal and supported by the radial arms A' of the pedestal A². A part of
this plate is cut out or left open and the gap is filled up by a short plate B which is
fixed at the same level as the plate A and corresponds therewith so that the two
plates A, B, form a complete ring as shown at Fig. 2.
heated by means of a gas heater C, forms the hot plate and as it is separate from
The plate B, which is
the plate A it does not heat the latter.
.
Supported by a number of radial arms t¹ which are connected to the vertical
revolving shaft E and have rollers or wheels at their outer ends, is a stepped or
double ring D, F, upon which the articles to be soldered are placed. As the ring D
revolves the wheels t, which help to support it, run upon the bed A.
The shaft E is driven by bevel gearing E¹ from a horizontal shaft E³ which may
be operated either by hand or by power.
The upper part F of the double ring D, F, has passed through it a number of
vertical rods I which are provided at their lower ends with rollers u which run
upon the plate A. The rods, the number of which is regulated by the capacity of
the machine, have secured to each of them, by means of a collar and pinching
screws, a cup G in which a lead or other weight is placed. The cups G can be
adjusted vertically to suit the size of tin being soldered, by sliding the collars up
or down on the rods I and then clamping them in position by means of the
screws s¹.
At a part of the plate A in front of the hot plate B, a cam or incline H is fitted.
This cam I prefer to term a "Montagne Russe "because of its similarity to that
apparatus.
When, during the rotation of the ring D, one of the rollers u of the rods I
encounters the cam H it mounts up it (as shown at Fig. 1) and in so doing raises
up the weight in the corresponding cup G. After the roller has travelled over the
top of the cam the weight forces the rod I and its roller to descend the other side
of the cam.
The action of the machine is very easy to understand. The machine is set in
motion and the plate B heated to the proper temperature whereupon the workman
takes the prepared tin and also its bottom, upon which a thin ring of solder has
been laid, and carefully fits them together. He now waits until one of the weights
is lifted up by the cam H when he quickly places the tin and its bottom upon the
revolving table or ring D. After the roller u of the weight has passed over the
top of the cam H the weight descends upon the tin and presses it and its bottom
close together. The pressure of the weight is exerted upon the tin during the
whole time it is passing over the hot plate B which latter is of course heated
throughout its length. After the tin passes over the plate B it continues to travel
round the machine until the roller u of its weight is again lifted up by the cam H

page_text: when it is quickly removed and replaced by another tin. The solder solidifies during
the time taken for the tin to travel round, from the hot plate B to the cam H.
It is to be noted that the use of the turn table or ring D avoids all friction of
the tin upon the plate A. The heat from the gas burner easily traverses the
ring D and uniformly fuses the solder all round the tin.
Experience shows, that, with a little study, a workman can solder with the
machine from 350 to 400 tins per hour.
All kinds of tins used in commerce for preserved food can be soldered by means.
of this machine.
The machine also serves to secure the usual india rubber washers to the covers.
of cases and tins made of tin plate. All that is necessary is to place the india
rubber washers upon the cover and then place the cover upon the revolving_table
on ring D. During the time the cover is travelling over the hot plate B the
washer is glued or stuck to the cover. It is not necessary to use the weights in
this operation.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
consider novel and desire to claim is :-
1. The combination, in a machine for soldering preserved food tins and cases, of
a fixed circular plate or bed one part of which is isolated from the rest and is heated
by gas, a turn table or ring which revolves above the fixed plate, and rods and
weights secured to the turn table and adapted, as the turn table revolves, to ascend
and descend a cam or incline fitted on the fixed plate, substantially as hereinbefore
described with reference to the drawings annexed.
2. A machine for soldering tins and cases, constructed, arranged, and operating
substantially as herein before described with reference to Figs. 1 and 2 of the
drawings annexed.
