COMPLETE SPECIFICATION.
A New or Improved Machine for Use in connection with the
Closing of "Lever Lid "' Tins.
1, WILLIAM WOOLNOUGH of 49, Belgrave Road, Ilford, Essex, Tinplate Worker, 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 a new or improved machine for use in connection with the
closing down of lever lid tins, so as to render the said tins absolutely air-tight.
In carrying my invention into practical effect, ny improved machine consists of a
suitably shaped frame preferably of cast iron, furnished with a table of sufficient size
designed to support the tin to be closed, which is capable of being raised vertically
by means of a cam arranged beneath the said table. Above the table I further
arrange an adjustable plate or disc the height of which, above the aforesaid table
may be regulated according to the size of the tin to be dealt with. This plate or
disc is furnished with a central hole or perforation through which passes one end
of a rod or spindle carrying a forked or tongued plate, the object of which, when
revolved in contact with the tin, is to form a rib, ridge or bulged portion upon the
said lid for effectually closing the tin, which operation is hereinafter more fully
described.
In order that my improved machine and the operation of same may be more "fully
understood I will now proceed to describe same with reference to the accompanying
drawings in which
Fig. 1 is a front elevation of my improved machine for closing down lever lid tins
Figs. 2 and 3 being respectively a side elevation and plan thereof, in the latter view
the chain, hereinafter refered to, being merely indicated by dotted lines.
Fig. 4 is a detailed view, partly in section, of the table and cam for 'raising same,
the second position being shown in dotted lines.

Like letters of reference indicate corresponding parts throughout the drawings.
My improved device consists essentially of a frame of cast iron or other. suitable
material a preferably of the shape shown in the drawings and which is furnished with
a basis b towards one end of which is cast or formed the hollow body or box d
containing the cam c mounted upon the end of the spindle cand designed to be
revolved by means of the gear wheel w, through the operating wheel w' mounted upon
spindle e which is actuated by the handle h through crank ¹. Above the aforesaid
cam c I arrange a table which is mounted or carried upon one end of the rod or
support one end of which is in contact with the cam c, said table being capable of
rising and falling according to the position of the said cam, and upon this table the
tin T is placed. Above the rising and falling table f I arrange an adjustable plate or
disc g capable of being regulated according to the size of the tin to any required
height, by means of the screw threaded bolts 'or extensions gland nuts. g. This
plate or disc is furnished with a central hole or perforation through which passes one
end of the spindle k carrying a tongued or forked plate m designed to enter the
lid m' of the tin T for the purpose of closing same as. hereinafter more fully described.
The spindle k carrying the forked plate m is furnished with a suitable toothed or
sprocket wheel and connected by means of-a-chain C-to-a-corresponding sprocket
wheel mounted upon the spindle; the lower end of which also carries a bevel wheel n
designed to be operated by the toothed quadrant q. Vertical rods or bolts v, v, are
further provided for strengthening the framing of the machine while the top or

page_text: horizontal arm a¹ of the frame is fitted or furnished with an elbow piece a² for
supporting and steadying the spindle k, the boss 61 being confined between the said
elbow piece and the horizontal arm a', while the projecting clip a³ is also provided
for supporting or steadying the end of the spindle k¹, and which acts as a brake
so as to prevent the spindle from shifting or turning when not in gear with the
quadrant 9, and retains it in position so as to readily engage or mesh with the said
quadrant when it is raised.
The operation of my improved nachine is as follows:-
C
The tin T, the lid m of which is furnished with a suitable packing ring or washer
secured in place under the edge of same, is placed upon the table with the lid in
position, the table is then raised by revolving the handle h which communicates the
motion to the wheel to through gear wheel w¹, thereby revolving the axis c' and the
cam c. When the table has been fully raised bringing the lid of the tin T forcibly
against the tongued or forked plate m, partially embedding the raised or projecting
part of the top of the tin in the aforesaid packing ring or washer, the quadrant q
then begins to engage with the bevel wheel n so that upon further revolving the
handle the spindle is revolved, the motion of which is communicated by means
of the chain c to the spindle & carrying the tongued or forked plate m which enters
or is contained within the recessed portion of the lid so that as it revolves it forms
a rib, ridge or bulged portion which is pressed out at the bottom of the said
recessed part of the lid and comes tightly against and under the inwardly projecting
circular flange of the tin, thus preventing the lid from shifting and becoming loose,
while it may be removed upon reasonable pressure being applied under the edge of
the lid, by means of any suitable tool, coin or the like, in the ordinary manner.
For the purpose of forming the said rib, ridge or bulged portion, the forked or
tongued plate m is made slightly larger than the bottom of the lid to be operated
upon, so that upon the said lid being brought forcibly against the tongued or forked
plate, it gives slightly and allows the said plate to pass to the bottom of the lid, so
that upon the plate being revolved, the aforesaid rib, ridge or bulged portion is
pressed out.
My improved machine is particularly designed and intended for closing lever lid
tins in a similar manner to that described and shown in my former Letters Patent
No. 16348 dated August 31st, 1895 and upon reference to which the object of this
present machine or device will be more fully understood.
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. The new or improved machine for use in connection with the closing of
lever lid tins, substantially as herein described and shown and for the purposes
specified.
2. The new or improved machine or device for use in connection with the closing of
. lever lid tins, comprising a rising and falling table such as f, operated by cam c
through gear wheels w, w¹, and spindles k, k', in combination with bevel wheel n and
quadrant, chain c in combination with suitable toothed or sprocket wheels and
tongued or forked plate m, the whole combined and arranged substantially as herein
described and shown and for the purposes specified.
