PROVISIONAL SPECIFICATION.
Improved Machine for Manufacturing Wasbers, Chain Links, and
similar Articles.
JAMES FORD of 39 Albert Grove, Newton (detached) near Manchester in the
County of Lancaster, foreman do hereby declare the nature of this invention to be as
follows:-
:-
My invention relates to the manufacture of washers, flat chain links and similar
articles which are punched out of sheet metal and themselves perforated with holes and
consists in an improved machine or combination of parts and mechanism for effecting
the punching of said articles out of scrap sheets and simultaneously punching the hole
or holes into them.
My improved machine consists of two side-frames mounted on a base plate and
connected at about their middle by a table. The side frames support in bearings
two shafts one above and one below the table which shafts are driven from the pulley
shaft of the machine by gearing so as to rotate at the same speed. The upper shaft
is formed with or has attached to it three excentrics the two outer ones of which have
the same throw and direction and are fitted with excentric straps and rods or their
equivalent. The excentric rods are connected to a slide, herein after called main slide
guided by guide-bars attached to the side frames, to which slide a die for the blanks
is attached.
Inside the die a stripper is guided by the same and attached to a vertical slide
arranged at the back of the main slide and guided by guides on a cross plate con-
necting the frame sides at the back of the main-slide. The stripper is formed with a
flange or its equivalent by which it rests upon the top of the toolbox or part of the
nainslide in which the said die for the blanks is fixed. The stripper is perforated
with a hole or holes for the punch or punches for perforating the blanks to pass
through and be guided thereby, these punches being attached to a central slide guided
in guidebars formed on or attached to the mainslide and connected by an excentric
rod and strap to the middle excentric of the top shaft, the throw of which may be the
same as that of the outer excentrics.
The bottom shaft carries in the middle an excentric, or its equivalent to which a
slide herein after called bottom slide is connected by an excentric rod and strap To
the bottom slide the punch for punching the blanks is attached, said punch being
perforated so as to form at the same time the die for the perforating punches, and
guided in a bush in the top of the table. The different excentrics are so arranged
relatively to each other that the slides connected thom operate as follows:-
The sheet or plate out of which the articles are manufactured having been placed
over the bottom punch while the bottom slide is at its lowest position and the other
slides at or near to their highest position, the mainslide is pushed down to within a
distance slightly greater than the thickness of the sheet or plate to be punched from
the top of the bush or table guiding the bottom punch. The latter then rises and
punches out the blank, which enters the top die and is pushed up into it by the bottom
punch. When the latter is at about the top of its stroke, the perforating punches
attached to the central slide descend and punch the holes into the blank, which remains
fixed on them and in the die for the blank while the top slide ascends and the bottom
slide descends. The stripper in the die for the blank is pushed up in it simultaneously
with the blank and resting upon the latter is carried up with it, until the slide attached
to the stripper comes against a stop., which may be conveniently formed by a screw
fixed to the cross plate connecting the frame sides at the back of the mainslide, which
screw projects into a slot of the stripper slide.

page_text: When the bottom of the slot comes against the screw the upward movement of the
stripper is arrested and the mainslide and central slide continuing their ascent,
the washer or similar article. is stripped off the punches and pushed out of the die.
The sheet is stripped off the bottom punch by the latter withdrawing below the top
of the table or bush guiding the punch. The end of the bottom shaft carries a cam
which acts upon one end of a vertical beam lever vibrating on a bracket attached to
the frame side and pulled against the cam by a spring. To the other end of the lever.
a horizontal rod is connected which passes through the frame side and carries inside
of the frame a flat tray turned up at one side. The cam is so shaped that while the
main and central slide risc, it moves the tray under the die for the blanks, so that
when the washer or similar article is stripped and drops out of the die, it falls upon
the tray. The cam then suddenly releases the lever and the spring pulls it so as to
draw the rod and tray attached to it vehemently to one side, whereby the washer is
flung off the tray into a shoot arranged at the side of the machine, which delivers it
into a suitable receptacle. The punchings from the washers or other articles drop
through the bottom die upon an inclined face on the bottom slide, which delivers
them at the back of the machine upon the floor or into suitable receptables.

Improved Machine for Manufacturing Washers, Chain Links, and
similar Articles.
I, JAMES FORD of 39 Albert Grove, Newton (detached) near Manchester in the
County of Lancaster, Foreman, 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 the manufacture of washers flat chain links and similar
articles which are punched out of sheet metal and themselves perforated with holes
and consists in an improved machine or combination of parts and mechanism for
effecting the punching of said articles out of scrap sheets and simultaneously punching
the hole or holes into them.
Figure 1 is a sectional elevation and Figure 2 a vertical transverse section on the
line XX figure 1 of my improved machine. It consists of two side frames A A
mounted on a base plate and connected at about their middle by a table B. The
side frames support in bearings two shafts Cono above and one below the table
which shafts are driven from the pulley shaft D of the machine by gearing so as to
rotate at the same speed. The upper shaft C is formed with or has attached to it
three eccentrics E E E the two outer ones E E of which have the same throw and
direction and are fitted with eccentric straps and rods F F or their equivalent. The
eccentric rods are connected to a slide G herein after called main slide guided by
guide bars A' A' attached to the side frames to which slide a die H for the blanks is
attached. Inside the die H a stripper J is guided by the same and its travel is limited
by the vertical slide K arranged at the back of the main slide and guided by guides
on a cross plate L connecting the frame sides at the back of the main slide. These
parts are shown in the local horizontal section figure 3. The stripper J is formed
with a flange J or its equivalent by which it rests upon the top of the tool box or
part of the main slide in which the said die for the blanks is fixed. The stripper Jis
perforated with a hole or holes for the punch M or punches for perforating the blanks
to pass through and be guided thereby, these punches being attached to a central
slide N guided in guide bars formed on or attached to the main slide and connected
by an eccentric rod F¹ and strap to the middle eccentric E' of the top shaft the throw
of which may be the same as that of the outer eccentric.

page_text: The bottom shaft C' carries in the middle an eccentric E or its equivalent to which
a slile G (shewn in horizontal section by Figure 4) hereinafter called bottom slide is
connected by an eccentric rod F and strap. To the bottom slide G₁ the punch M¹
for punching the blanks is attached said punch being perforated so as to form at
the same time the die for the perforating punches and guides in a bush B' in
the top of the table B.
The different eccentrics are so arranged relatively to each other that the slides
connected to them operate as follows:-
The sheet, plate or strip out of which the articles are manufactured having been
placed over the bottom punch M while the bottom slide G¹ is at its lowest position
and the other slides at or near to their highest position the main slide G is pushed
down to within a distance slightly greater than the thickness of the sheet, plate or
strip to be punched from the top of the bush B' and table B guiding the bottom
punch M'. The latter then rises and punches out the blank which enters the top die
and is pushed up into it by the bottom punch. When the latter is at about the top or
its stroke the perforating punches M attached to the central slide N descend and
punch the holes into the blank which remains fixed on them and in the die for the
blank while the top slide G ascends and the bottom slide G' descends. The stripper J
in the die for the blank is pushed up in it simultaneously with the blank and resting
upon the latter is carried up with it until the slide K comes against a stop O which
may be conveniently formed by a screw fixed to the cross plate L connecting the
frame sides at the back of the main slide which screw projects into a slot of the
stripper slide.
When the slide K comes against the screw the upward movement of the stripper J
is arrested and the main slide and central slide N continuing their ascent the washer
or similar article is stripped off the punches and pushed out of the die. The sheet is
stripped off the bottom punch by the latter withdrawing below the top of the table or
busb guiding the punch. The end of the bottom shaft carries a cam P which acts
upon one end of a vertical beam lever Q vibrating on a bracket attached to the
frame side and pulled against the cam by a spring Q. To the other end of the
lever a horizontal rod R is connected which passes through the frame side and
carries inside of the frame a flat tray S turned up at one side. The cam is so
shaped that while the main and central slide rise it moves the tray under the die
for the blanks so that when the washer or similar article is stripped and drops out of
the die it falls upon the tray. The cam then suddenly releases the lever and the
spring pulls it so as to draw the rod and tray attached to it vehemently to one side
whereby the washer is flung off the tray into a shoot T arranged at the side of the
machine which delivers it into a suitable receptacle. The punchings from the washers
or other articles drop through the bottom die and between the two eccentrics onto the
floor.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I would state that I am aware that
washers and similar articles have been punched from sheets of metal, the blank being
held in a die whilst it is perforated by the punch and that the slides and punches for
effecting these operations have been worked from shafts situated at the two sides of a
central table and I therefore make no general claim to these points, but what I
claim is:
:-
1. A machine for manufacturing washers, chain links and similar articles in which
there is a table with a shaft on each side of it one shaft having fixed to it an eccentric
or eccentrics actuating a punch for cutting out the blank from a sheet plate or strip of
metal, and the other shaft having fixed to it an eccentric or eccentrics actuating a slide
carrying a die to receive the blank when cut and having attached to it a second slide
worked by an eccentric on the shaft and carrying a punch or punches to perforate the
blank.
2. In machines for manufacturing washers, chain links and similar articles the

page_text: combination of the shafts 'C C', the eccentrics -E, E', E, the rods F, F1, F2, the
slides G, G¹, and N, the punches M M', and the stripper J-substantially as described.
3. In machines such as are referred to in the preceding claims the tray for receiving
the finished blank actuated by a lever cam and spring substantially as described.
4. The improved machine for manufacturing washers, chain links and similar
articles.substantially as described and shown in the drawings.
