I, JEAN JULES LAFFITTE of 102 Avenue Parmentier, Paris, France, Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
My invention has reference to solder plates or tablets for use in soldering or
uniting ironwork, steelwork or the like.
Hitherto solder plates or tablets have been made rectangular and smooth and
when it has been required to effect a soldering, a piece of the required size has
been cut from the plate by means of shears or other tools. This leads to loss of
time and considerable waste of the material. The object of the present invention
is to obviate this objection.
According to this invention I make the plates or tablets with divisions or lines
on one of its faces dividing it off into squares and weakening or partly separating
it along these lines. It is thus easy by means of a chisel or simply by hand to
entirely separate a piece of the dimensions required according to the section of the
article to be soldered. The invention is not limited to dividing off the plates into
squares, as various forms curved, circular or other may be marked off on the plates
by lines of cavities or otherwise.
Instead of dividing off the plates or tablets on one side only they may be
divided off on both sides. This has the advantage of facilitating the escape of the
gases and of the excess melted material and thereby obtaining a rapid commence-
ment of adhesion by preventing compressed air making flaws in the soldering.
With these plates there is no risk of any flaw as the soldering is always.
homogeneous.
Plates or tablets with a base of copper can be made in the same way.
The plates can be marked or divided off by rolling or by any suitable means
of compression.
Wire gauze may be enclosed in the plates.

facturer, 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 :-

gauze may be enclosed in the plates.
Referring to the accompanying illustrative drawings,
Figures 1 and 2 are respectively a plan and a cross section of a solder plate or
tablet divided into squares by means of straight grooves or furrows intersecting
one another at right angles.
Figures 3 and 4 are similar views of a solder plate or a tablet divided into
squares of smaller size, the dividing grooves or furrows being indicated by their
lines in Figure 3.
The thick lines in Figure 3 illustrate by way of example the manner in which a
solder plate or tablet, divided into squares as shown, should be broken up along the
edges of the squares for the purpose of obtaining pieces of solder of similar shape
to the articles of rectangular and circular contour to be soldered.
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 I
claim is :-
A solder plate, sheet or tablet with or without the addition of wire gauze,
divided on one or on both sides or faces into squares or other areas of any
desired shape and size by means of grooves furrows, cavities, indentations,
perforations or the like substantially as herein before described and for the purpose
specified.
