Improvements in Machines employed in the Manufacture of Metal
Boxes, Canisters, and the like.
I, FREDERICK HENRY BREININGER, of 66 Paradise Road, Clapham, in the
County of Surrey, Engineer, do hereby declare the nature of this invention to be as
follows:
-:
My invention relates to improvements in machines employed in the manufacture
of metal boxes, canisters, and the like.
The object of my invention is to construct an improved machine for "double-
seaming," grooving, and otherwise treating the edges and surfaces of sheet-metal
articles with greater facility and accuracy than is possible with the machines
ordinarily used for like purposes. An important feature of my said invention is the
employment of novel adjusting-mechanism for the seaming, grooving, and bending
rollers, such as is hereinafter exemplified.
According to my invention I provide in suitable bearings in the frame of the
machine, a rotatable chuck to receive the article to be treated. The said chuck is
rotated by any suitable means; the article is kept in place thereon by a rotatable
disc secured upon a rod which is movable in suitable guides by a treadle or otherwise,
and is employed to maintain the requisite pressure upon the disc.
To the said chuck a cam or roller path is attached, which turns therewith, and is
of a form corresponding to that which it is desired to impart to the article.
Upon the framing of the machine are suitable guides, preferably in line with each
other at opposite sides of the aforesaid chuck, which receive sliding carriages.
These carriages are provided with rollers which engage with the aforesaid cam
or roller path so that the carriages are reciprocated thereby during the rotation of
the chuck.
Upon the carriages I mount slides which carry seaming, grooving, or bending
rollers, which, by reason of their shape and situation, are adapted to operate upon
the article in the manner desired.
The said slides can be operated at any instant to cause the seaming, grooving, or
bending-rollers to move independently of the movement of the carriages, to approach
and press upon the article or to recede therefrom. It is an important feature of my
invention that this independent movement can be effected during the movement of
the chuck and of the carriages. The mechanism for moving the slides relatively
to the carriages may consist, for instance, of wedges provided with toothed racks
and adapted to slide in the said carriages and to reciprocate the slides thereon ;
movement of the wedges can be effected by toothed sectors or pinions carried upon
a shaft supported in bearings on the frame, the sectors or pinions being geared to
the toothed racks and adapted to have end wise motion relatively thereto, or being
otherwise arranged so as not to interfere with the movement of the carriages and
the toothed racks in company. The said sectors or pinions must be arranged so as
to be capable of receiving rotation at any moment from the shaft upon which they
are carried; for instance a feather key may be provided upon the shaft, to enter
suitable key-ways in sectors or pinions arranged to slide thereon. Or, for like
purposes, the said shaft may be of angular cross-section, and the sectors or pinions
provided with axial holes of corresponding shape.
Placing the aforesaid rollers at opposite sides of the chuck instead of at one side
as has been customary hitherto, equalizes the stresses in the machine and conduces
to easy working and diminution of wear and tear. Further, the control of all

page_text: these rollers by one mechanism simplifies the construction and working of the
apparatus.
Obviously the machine can be used, by employing suitable cutting-discs and
rollers on the slides, for trimming rough edges, for beading, and for forming a
milled edge, as well as for the operations hereinbefore mentioned.

COMPLETE SPECIFICATION.
Improvements-in-Machines employed in the Manufacture of Metal
Boxes, Canisters, and the like.
I, FREDERICK HENRY BREININGER, of 66 Paradise Road, Clapham, in the
County of Surrey, Engineer, 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 :-
My invention relates to improvements in machines employed. in the manufacture
of metal boxes, canisters, and the like.
The object of my invention is to construct an improved machine for "double-
seaming," grooving, and otherwise treating the edges and surfaces of sheet-metal
articles with greater facility and accuracy than is possible with the machines
ordinarily used for like purposes. An important feature of my said invention is
the employment of novel adjusting-mechanism for the seaming, grooving, and
bending rollers, such as is hereinafter exemplified.
In the accompanying drawings which illustrate a convenient and advantageous
mode of carrying my invention into practice
Figure 1 is a front elevation, and
Figure 2 is a side elevation of the machine.
According to my invention I provide in suitable bearings in the frame or
standard A of the machine, a rotatable chuck B to receive the article to be treated.
The said chuck is driven through a shaft C and gear wheels D, D. The article to
be treated is kept in place on the chuck by a rotatable disc E secured upon a
spindle E' which is movable vertically in suitable guides Es by a treadle F, said
treadle being connected to the spindle E' through an adjustable rod F¹ and a
forked lever G, the latter being pivotted to the frame at G₁ and balanced by
a weight G. The treadle is employed to maintain the requisite pressure upon
the disc E..
In the chuck B or in a part attached thereto, a cam or groove or roller path B'
is provided which turns with the chuck and is of a form corresponding to that which
it is desired to impart to the article to be treated.
Upon the framing of the machine are suitable guides H, preferably radial and in
line with each other at opposite sides of the aforesaid chuck, which guides receive
sliding carriages J. These carriages are provided with rollers J which engage
with the aforesaid cam or roller path B' so that the carriages are reciprocated thereby
in their guides in accordance with the shape of the cam groove during the rotation
of the chuck.
Upon the carriages J, I mount slides K which carry seaming, grooving, or bending
rollers K Said rollers by reason of their shape and situation, are adapted to
operate upon the article in the desired manner.
The said slides K can be operated at any instant to cause the seaming, grooving,
or bending-rollers to move independently of the movement of the carriages J, to
approach and press upon the article or to recede therefrom. It is an important
feature of my invention that this independent movement can be effected during the
movement of the chuck B and of the carriages J. The mechanism for moving the

page_text: slides relatively to the carriages consists of wedges L provided with toothed racks L'
at their lower ends and adapted to slide vertically in the carriages J and to recipro-
cate the slides K thereon; movement of the wedges is effected by toothed sectors M
or pinions carried upon a shaft M' supported in bearings on the frame, the sectors
or pinions being geared to the toothed racks L' and arranged so as not to interfere
with the radial movement of the carriages J and the toothed racks L' in company.
For example the sectors or pinions are arranged to slide on the shaft M¹ but not to
turn thereon being connected thereto by a feather key or otherwise for this purpose.
The sectors are shrouded at the sides to embrace the racks and maintain them in
gear during the sliding movements of the carriages J. The shaft M' is turned by
the operator when required through gearing N, N and a handle N.
means the wedges J can be raised and caused to press inward the slides K thereby
giving the final pressure on the article undergoing treatment. A reverse movement
of the handle N serves to release the pressure on the operating rollers.
By this
By placing the aforesaid rollers K' at opposite sides of the chuck instead of at
one side thereof as has been customary hitherto, the stresses in the machine are
equalized and the working of the machine is facilitated and wear and tear reduced.
Further, the control of the rollers by one handle simplifies the construction and
working of the apparatus.
Obviously the machine can be used, by employing suitable cutting-discs and
rollers on the slides K, for trimining rough edges, for beading, and for forming a
milled edge as well as for the operations hereinbefore mentioned.
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 :-
1. In machines for seaming, beading, trimming or otherwise treating metal boxes,
canisters and the like, the combination, with the chuck for receiving the article to
be treated, of a cam groove or its equivalent, and sliding carriages engaging said
grooves or the like and carrying the operating rollers arranged on diametrically
opposite sides of the chuck, substantially as described for the purposes specified.
2. The combination with the sliding carriages J of the upper slides K carrying
the rollers, and the means for applying the final pressure on the article to be treated
whether the chuck be stationary or rotating, substantially as described.
'
3. A machine constructed substantially as described with reference to the
drawings and operating as, and for the purposes, specified.
