PROVISIONAL SPECIFICATION.
Machinery for "Punching" or Rivetting together the Edges of the
Plates of Sheet Iron, Sheet Tin, or other Sheet Metal Kegs,
Cans, Cases, and other like Goods.
I, FREDERICK JOHN TAYLOR, of 77 Hartington Road, Liverpool, in the County of
Lancaster, Engineer, do hereby declare the nature of my said invention to be as
follows:-
The goods in connection with which the machinery according to this invention.is
intended mainly to be used are those made of sheet iron, sheet tin, and other thin
sheet metal goods, and the one portion amongst others of the goods to which it is
more particularly suitable for operating upon is the edges of plates forming the
bottoms and sides of kegs, cans, cases or other receptacles or goods, the bottoms being
of outwardly dished form. The cross sectional figure of these goods may be circular
or other curvilinear form, or of square, or other polygonal configuration.
The object of the present invention is mainly to provide machinery by which the
edges of the plates of goods of the nature above specified may be quickly and
correctly or well punched or rivetted as the case may be, and also which shall be 50
constructed and arranged to operate that the stresses to which and whilst it is
subjected in operation shall be borne without the parts being materially moved or
thrown out of their normal and correct position, this refers more particularly to the
inner dies hereinafter described.
In the following Specification setting forth the nature of my invention, for the
sake of simplicity I describe a machine for rivetting together the parts of the goods
and the kind of goods, and the portions thereof, described and being operated upon
by the machine, namely, a cylindrical bottom of concave form, such as is commonly
employed for holding paint, oil, or other material; the sole alteration necessary to
render the machine applicable as a punching machine being the provision of punches,
and corresponding apertures in the dies; in lieu of the rivetting provisions hereinafter
specified.
In a machine according to my invention there is provided a plurality of dies, say
six, and a corresponding number of "holding up" blocks or anvils, the function of
the holding up blocks being to hold the rivets in position before and during the
process of rivetting, whilst the function of the dies is to press and form the ends of
the rivet shanks into rivet heads, both arranging and constructing the machine in
such a manner that the line of the direction of thrust passes through the surface or
portion of support of the said. die; or that such portion or surface of support lies in
the same plane as the line of thrust and that of the rivets:
According to one arrangement by which this is conveniently effected, there is used
a central shaft which both imparts the outward movement. to the holding up blocks
and affords the means of supporting them in the position and. manner just described.
The outward movement. is effected by raising the shaft, when it presses upon the
inclined portion of the blocks and forces them. apart; the upper part or bearing.
portion or surface of the blocks and that of the shaft being, parallel. The inward
movement is imparted to the blocks by springs.
The machine may be arranged to operate horizontally, the dies being moved
through levers of the first order connected to and operated by a vertical sleeve
mounted on an annular shaft-in which also the block supporting shaft works-such
sleeve being worked by connecting rods and cranks of a horizontally arranged shaft.
On this shaft a cam by which the block supporting shaft is operated is also mounted
or formed. Tlie die levers are supported in adjustable bearings and provided with
screws or equivalent adjusting devices by which they may be adjusted laterally with

page_text: respect to the axis of the machine; and suitable moveable blocks may be used in
connection with the holding up blocks, said dies and holding up blocks having
motion imparted to them.
The holding up blocks are moved radially from a common axis and the dies are
moved backwards and forwards in the same radial lines outside the blocks, and both
may be conveniently arranged to slide or move in and he held by the same slides and
guides, and, to suit the form of the bottom of the keg; the said blocks are formed of
a corresponding shape, and are also provided with apertures to take and hold the
rivet heads. In operation the keg with the rivets already in position is placed over
the holding up blocks which are then forced radially outwards until the edges bear
upon, or the recesses above specified bear upon, and hold the rivet heads. While in
this position the dies are caused to be moved radially inwards and press upon the ends
of the rivet shanks and form them into heads.
It is important that during the process of rivetting, that is when the pressure is
being put upon the rivets, they should be held firmly and to assure good and effective
rivetting being accomplished it is necessary that the firmness or rigidity should be as
perfect as is practically possible. This obtain by providing the machine with a
device for supporting the holding up blocks by which the distance from the axis of
the machine may be varied, and varied sized goods operated upon by the machine.
The parts are mounted in a suitable frame supported upon a bed, and the machine
may be operated by any suitable source of power.

COMPLETE SPECIFICATION,
Machinery for "Punching" or Rivetting together the Edges of the
Plates of Sheet Iron, Sheet Tin, or other Sheet Metal Kegs,
Cans, Cases, and other like Goods.
I, FREDERICK JOHN TAYLOR, of 77, Hartington Road, Liverpool, in the County of
Lancaster, Engineer, do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The goods in connection with which the machinery according to this Invention is
intended mainly to be used are those made of sheet iron, sheet tin, and other thin
sheet metal goods, and the one portion amongst others of the goods to which it is
more particularly suitable for operating upon is the edges of plates forming the
bottoms and sides of kegs, cans, cases, or other receptacles or goods, the bottoms
being of outwardly dished form. The cross sectional figure of these goods may be
circular or other curvilinear form; or of square or other polygonal configuration.
The object of the present Invention is mainly to provide machinery by which the
edges of the plates of goods of the nature above specified may be quickly and
correctly or well punched or rivetted, as the case may be, and also which shall be so
constructed and arranged to operate that the stresses to which it is subjected in
operation shall be borne without the parts being materially moved or thrown out of
their normal and correct position, this refers more particularly to the inner dies or
holding up blocks, hereinafter described.
In the following specification setting forth the nature of my Invention, for the sake
of simplicity, I describe a machine for rivetting together the parts of the goods, and
the kind of goods and the portions thereof described, namely, a cylindrical bottom of
concave form, such as is commonly employed for holding paint oil or other material;
the sole alteration necessary to render the machine applicable as a punching machine
being the provision of punches and corresponding apertures in the dies in lieu of the
rivetting provisions hereinafter specified.

page_text: In a machine according to my Invention there is provided a plurality of dies, say
six, and a corresponding number of "holding up" blocks .or anvils, the function of
the holding up blocks being to hold the rivets in position before and during the
process of rivetting, whilst the function of the dies is to press and form the ends of
the rivet shanks into rivet heads, both dies and holding up blocks having motion
imparted to them.
The holding up blocks are moved radially from a common axis, and the dies are
moved backwards and forwards in the same radial lines outside the blocks. and both
may be conveniently arranged to slide or move in and be held by the same slides and
guides, and to suit the form of the bottom of the keg; the said blocks are formed.of
a corresponding shape and are also provided with apertures to take and bold the rivet
heads. In operation, the keg, with the rivets already in position, are placed over the
holding up blocks which are then forced radially outwards until the edges bear upon
or the recesses above specified bear upon, and hold the rivet .heads. While in this
position the dies are caused to he moved radially inwards and press upon the ends of
the rivet shanks, and form them into heads.
It is important that during the process of rivetting, that is, when the pressure is
being put upon the rivets, they should be held firmly, and to assure good and
effective rivetting being accomplished, it is necessary: that the firmness or rigidity
should be as perfect as is practically possible. This 1 obtain by providing the machine
with a device for supporting the holding up blocks, and arranging and constructing
the machine, in such a manner, that the line of the direction of thrust passes through.
the surface or portion of support of the said die, or that such portion or surface of
support lies in the same plane as the line of thrust and that of the rivets.
According to one arrangement by which this is conveniently effected, there is used
a central shaft which both imparts the outward movement to the holding up blocks
and affords the means of supporting them in the position and manner just described.
The outward movement is effected by raising the shaft when it presses upon the
inclined portion of the blocks and forces them apart; the upper part or bearing
portion or surface of the blocks and that the shaft being parallel. The inward
movement is imparted to the blocks by springs.
.
The machine may be arranged to operate horizontally, the dies being moved
through lovers of the first order .connected to and operated by a vertical sleeve
mounted on an annular shaft-in which also the block supporting shaft works—such
sleeve being worked by connecting rods and cranks off a horizontally arranged shaft.
On this shaft a cain by which the block supporting shaft is operated is also mounted
or formed. The die levers are supported in adjustable bearings and provided with
screws or equivalent adjusting devices by which they may be adjusted..laterally with
respect to the axis of the machine; or .suitable move.ble blocks may be used in
connection with the dies and holding up blocks, by which the distance from the
axis of the machine may be varied, and varied .sized goods operated upon. by the
machine.
The parts are mounted in a suitable. frame supported upon a bed, and the machine
may be operated by any suitable source of power.
The nature of my Invention, and the manner of working it, will be understood
upon reference to the accompanying .drawings and to the following description of
them.
Figure 1, is a part:sectional elevation illustrative of the machine, (which is: shown
adapted for.rivetting).
Figure 2, is a plan of same; and
Figure 3,.shows an outside.elevation of it.
Figures 4, 5, and 6, are details of the machine.
In describing the drawings, I will, for convenience confine the description of the
machine illustrated, as used as a rivetting machine, it being understood.of course
that, by employing proper male and female dies it can be used as a punching
machine.
With reference to the drawings, a are the rivetting dies eightinaall;—which are

page_text: :
adapted to slide between ordinary guides having inclined bearing edges; care
the holding up biocks-four in number-having feet e' adapted to move under the toe
of the dies a; d is the central shaft or spindle, which is arranged to move up and
down in the fixed hollow guide y, and to support the blocks ce are the rocking arms
by which the dies a are moved to and fro; and f is a sleeve, mounted on the guide y,
and provided with cams by which the arms e are operated.
U is the table plate, U the frame, and U the base of the machine. V is a crank
shaft, supported from the table U by hangers W. and is adapted to operate the cam
sleeve by its cranks X and connecting rod Y. This crank is also adapted to operate
the central shaft d through the tapet lever Z, link Z', and lever mounted at one
end and at the other provided with a jaw working over a pin Z3 in the spindle d, the
actuation of the lever Z being effected by the crank coming in contact with its end,
each revolution.
Referring to the detail of the dies and holding up blocks, a¹ are apertures in the
end of the dies, by which the rivet shank is rivetted up into a semicircular or
equivalent form, and is a projecting ledge which bears upon the rivet head when
the can or article is in position and the blocks moved forward ready for rivetting:
this condition of things is shown in detail in Figure 4, in which is the rivet, s the
side metal of the article, and the bottom.
The action of the spindle or shaft d, is, that when it is raised by the gear herein-
before described, its head presses upon the inclined surfaces of the inner sides of the
blocks c and forces them apart radially until it comes into the parallel portion above
the coned part shown in dotted lines (see Figures 1 and 4). When in this position,
it affords a support to the thrust of the dies a, when in operation upon the rivets,
and resists the stresses, the direction of thrust passing through the head of the
spindle d. Substantially the same action and result follows when the machino is
used for punching holes in articles of the kind described, the blocks c serving as
female dies or anvils.
The converse arrangement of means for operating the blocks c consists in employing
a coned head to the spindle d, in which case the blocks c will not require a coned
portion.
With respect to the construction and operation of the dies a, these are made with a
bead piece in which the rivetting hollow is provided, and a back piece, said two parts
being connected by bars a² (see Figures 5 and 6). In order to adapt the machine to
operate upon different sizes of articles, I provide loose blocks which fit in the dies
between the head and back pieces, and on either side of the head of the levers e.
The action of the dies is that when the can or other article has been placed in position
and the blocks c pressed forward in position ready for rivetting by the spindle d, the
further movement of the crank pulls down the cam sleeve and cams; by this
action the levers e are pressed outwards and their heads, which lie in the dies a,
inwards, so causing all the dies to move radially inwards, and pressing upon the rivet
shanks, rivetting them up into heads. The action is then complete, the article being
removed when the dies a and blocks c separate.
The return action of the dies a and blocks c may be effected by springs c³, acting in
compression, and springs e', acting in tension.
It will be evident the machine illustrated may be used to operate upon articles in
which four rivets only are required as well as eight; and in like manner a six die
machine may be used to operate upon three; or such machines may be used to
operate upon articles requiring a different number of holes to be punched, or rivets to
be rivetted, by effecting the operation in sets.
The converse action and arrangement of parts of machines described under this
invention may be employed, but although they are possible, I prefer the respective
disposition or arrangement of dies and blocks herein specified.
It will now be clearly seen that by employing punches and dies and corresponding
recesses in the holding up blocks specified in the above machine, in lieu of the form
of devices shown, it could be used to punch holes in the bottom and body of cans or
- other articles to receive the rivets.

page_text: 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. A machine for the purposes specified, having a plurality of dies adapted to be
operated simultaneously and upon the rivets when employed in a rivetting machine,
and upon the article when as a punching machine; substantially as herein described.
2. A machine for the purposes specified, having a plurality of radially arranged
dies, and holding up blocks or anvils, said dies being adapted to operate simultaneously
