Improvements in the Manufacture of Wrought Metal Mouldings
for Fenders, Fender Curbs, and Ash Pans.
We, GEORGE HOLLAND and BENJAMIN ADDICOTT, trading as Addicott & Holland, of
Staniforth Street, Birmingham, in the County of Warwick, Manufacturers, do hereby
declare the nature of our said invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
Our invention has for its object improvements in the manufacture. of wrought
metal mouldings for fenders, fender curbs and ash pans by which we are able to pro-
duce them more rapidly and at less cost than has hitherto been the case. Such
mouldings have up to the present time been generally produced by drawing strips of
metal through dies on a draw bench and also sometimes by pressure under vertical
presses between dies.
In order that our invention may be clearly understood and more easily carried into
practice we have illustrated our new process or manufacture in its various stages
upon the accompanying sheet of drawings, but it must be clearly understood that
while the various operations there described will give satisfactory results when
applied to such like sheet brass mouldings as the one illustrated as an example in
this specification, that one or more steps in the process of manufacture may be
omitted in plainer or less difficult moulding or that an additional step or steps to
those about to be enumerated may be necessary when more complicated sections of
mouldings are desired, but for general use the steps enumerated will be found
sufficient to enable others to practice our invention without difficulty.
Figure 1 represents in section a brass or other strip of wrought metal A cut from a
sheet or rolled to the required width.
Figure 2 represents the same strip A with the edges a¹ and a² turned up at an
angle so as to be ready to feed into the rolls.
Figure 3 shews the strip A after having passed through a pair of rolls so as to be
roughly shaped to the desired sectional configuration.
Figure 4 shews the strip A after passing through more exact rolls or through a more
exactly finished space in the same set of rolls.
Figure 5 shews the strip A after having the edges a¹ and a² bent in a folding
machine so as to bear the necessary relationship to the moulding or front portion.
Figure 6 is a perspective view of a piece of finished moulding A ready to make up
into a fender, fender curb or ash pan front.
Figure 7 is a side sectional elevation of a part of a folding machine operating upon
the strip A.
Figure 8 is a similar sectional elevation to Figure 7 but shewing a bar T used
instead of the roll R.
In our new process of manufacturing fender, fender curbs and ash pan fronts we
commence either from wrought sheet metal from which we cut a long strip such as
is shewn in section at A Figure 1 or we commence with a rolled strip such as A of
suitable width and of any length. We then turn up the edges a¹ and a² in a
folding machine such for instance as is shewn at Figures 7 and 8 the strip A being

folding machines and the tool edge P having been adjusted to proper position against
the plate A is lifted by means of the usual lever handle or handles L which gives the
desired bend. These parts a¹ and a² may however be turned in rolls instead of the
folder or this operation may sometimes he dispensed with in which case the flat strip A

is brought to a such like condition as is seen at Figure 3 in the rolls.
however the bends as seen at Figure 2 are not previously made along the strip the
corners may be simply turned up so as to easily enter the rolls and in this case the
strip should be carefully guided between guide bars extending near to the bite of
the rolls and be kept down either under a roll or rolls or under a guide piece.
We then pass the strip A as seen at Figure 3 into other rolls or through a more
exact opening in the same rolls which better finishes the strip to the desired
configuration as seen at Figure 4. We then apply the strip to a folding or other
machine and turn the edges a¹ and a² so as to stand at the proper angle to the
moulding as seen at Figures 5 and 6. In carrying out this latter and final operation
we may use in the folding machine a strip of metal T instead of the usual roller R
and having the sharper angle t¹ so as to bring the angles a³ at somewhat sharper but
otherwise this operation is performed as herein before described in relation to Figure 2.
We do not confine ourselves to the particular moulding herein given as an example
of our new process as we may make many other designs suitable for the particular
purpose herein set forth. When the moulding is formed it is worked up into fender
or fender curb fronts and ends or into the fronts of ash pans. We may also dispense
with one or more of the operations such for instance as in the case of thin soft
metal we may bring it to the desired sectional configuration by one passage through
the rolls and by one operation in the folder upon one edge only.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we

fenders, fender curbs, and ash pans from a sheet or strip of metal such as A by the
process of rolling or by folding and rolling and folding substantially as herein set
forth and as illustrated upon the accompanying sheet of drawings.
