PROVISIONAL SPECIFICATION.
Improvements in Machinery or Apparatus employed in the Manu-
facture of Tin Boxes, Cans, Canisters, and the like.
I, RENVILLE ANSELL, of 40, Gloucester Road, Croydon, in the County of
Surrey, Engineer and Millwright, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in machinery or apparatus for "rolling
on "the bottoms of tin boxes, cans, canisters and the like, whereby the said
bottoms are attached to the boxes in a better and more speedy manuer than
hitherto.
In carrying out my invention on a suitable bed plate, I mount two headstocks,
the spindle of the fixed stock carrying a chuck or face plate shaped on the edge to
receive the flange on the edge of the bottom of the box; the spindle of the poppet
head carries a gripping plate for the purpose hereinafter described and the head
can be moved forwards and backwards by means of a rack and a toothed segment
operated by a lever and a link jointed to a lever connected to a treadle, which
treadle is also connected by means of a link and lever to a clutch pulley on the
spindle of the fixed headstock. Above the chuck or face plate is arranged what I
call a "rolling on plate," the edge of the said plate being shaped to correspond
with the edge of the chuck or face plate. The said "rolling on plate" is carried
by a cross head sliding on uprights fixed to the bed plate and springs are placed
between the underside of the said cross head and the bed plate and between the
upper side of the cross head and another cross head sliding on the said uprights and
connected by rods to the treadle mechanism.
The operation is as follows:-
The bottom of the box (the edge of which is doubled or folded outwards to form
a trough to receive the edge of the bottom end of the box as usual) is placed on the
chuck or face plate and the edge of the bottom of the box is held in the said trough
and the lid placed on the box; the treadle of the machine is now depressed and
will simultaneously move forward the poppet head so as to press the gripping plate
against the lid of the box and bring the edge of the bottom end of the box into the
trough in the bottom of the box, the pressure of the gripping plate being regulated
by a spring; the "rolling on" plate will be moved downwards so as to bring its
edge against the turned up portion of the box-bottom and the clutch pulley will be
put in gear and the spindle being thereby revolved will rotate the box, the two
sides of the turned up portion of the bottom being pressed by the action of the
rolling on plate and the chuck against the edge of the end of the box so as to
securely fix on the bottom and make a good and tight joint.
The treadle being released the parts are carried back to their normal position
by a counterweight, the box falls out and another one is placed in position and
so on.

Improvements in Machinery or Apparatus employed in the Manu-
facture of Tin Boxes, Cans, Canisters, and the like.
I, RENVILLE ANSELL, of 40, Gloucester Road, Croydon, in the County of
Surrey, Engineer and Millwright, 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 machinery or apparatus for "rolling
on the bottoms of tin boxes, cans, canisters and the like, whereby the said
bottoms are attached to the boxes in a better and more speedy manner than
hitherto.
In carrying out my invention on a suitable bed plate I mount two headstocks,
the spindle of the fixed stock carrying a chuck or face plate shaped on the edge to
receive the flange on the edge of the bottom of the box; the spindle of the poppet
head carries a gripping plate for the purpose hereinafter described and the head
can be moved forwards and backwards by means of a rack and a toothed segment
operated by a lever and a link jointed to a lever connected to a treadle, which
treadle is also connected by means of a link and lever to a clutch pulley on
the spindle of the fixed headstock. Above the chuck or face plate is arranged
what I call a "rolling on plate," the edge of the said plate being shaped to corre-
spond with the edge of the chuck or face plate. The said "rolling on plate" is
carried by a cross-head sliding on uprights fixed to the bed plate and springs are
placed between the underside of the said cross-head and the bed plate and between
the upper side of the cross-head and another cross-head sliding on the said uprights
and connected by rods to the treadle mechanism.
In order to enable my invention to be fully understood I will describe how it
can be carried into practice by reference to the accompanying drawings, in
which

Figure 1 is a side elevation partly in section of my improved machine for
rolling on" the bottoms of tin boxes, cans, canisters and the like.
Figure 2 is an end view, partly in section, of the same.
Figure 3 is a section of part of the machine drawn to an enlarged scale shewing
a box in position for being operated upon, and
Figure 4 is a section of the box with the bottom "rolled on."
Similar letters in all the figures are used for similar. parts.

d the spindle thereof carrying the chuck or face plate e shaped on the edge as
shewn to adapt it to receive the flange on the edge of the bottom of the box; fis

rack and j the toothed segment for moving the poppet head f, the said segment

treadle n; o is the link and p the lever connecting the treadle to the clutch
pulley on the spindle d of the headstock c. r is the "rolling on" plate the
edge of which is shaped as shewn to correspond with the edge of the chuck or face
plate es is the cross-head carrying the "rolling on" plate r, the said cross-head
sliding on the uprights t, t fixed to the hed plate a; u, u are the springs placed
between the cross-head and the bed plate a, and u', u' are the springs between
the cross-heads and the cross-head sliding on the uprights t, t; w, w are
rods counecting the cross-head to the cross bar x which by means of the rod y is
connected to the lever m jointed to the treadle n.
The operation is as follows:-
The bottom A of the box (the edge of which is, as shewn in Figure 3, doubled
or folded outwards to form a trough to receive the edge of the bottom end of the
box as usual) is placed on the chuck, or face plate e and the edge. of the bottom of

the box is held in the said trough z the lid B being placed on the box; the treadle n
of the machine is now depressed and will simultaneously move forward the poppet
head f so as to press the gripping plate h against the lid B of the box and maintains
the edge of the bottom end of the box in the trough z in the bottom of the box, the
pressure of the gripping plate h being limited by the spring a'; the "rolling on
plater will at the same time be moved downwards so as to bring its edge against
the turned up portion of the box bottom and the clutch-pulley 9 will be put in gear
and the spindle d being thereby revolved will rotate the box, the two sides of the
troughed portion of the bottom being pressed by the action of the "rolling on
plater and the chuck or face plate e against the edge of the end of the box so as to
securely fix on the bottom and make a good and tight joint as shewn by the sectional
view of the box shewn in Figure 4.
"
The treadle being released the parts are carried back to their normal position by
the counterweight C, the box falls out and another one is placed in position and
so on.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
:-
The combination of parts forming the improved machine or apparatus for rolling
on the bottoms of tin boxes, cans, canisters, and the like, the said parts being
arranged and operating substantially as hereinbefore described and illustrated in
Figures 1, 2 and 3 of the accompanying drawings.
