PROVISIONAL SPECIFICATION left by the said Edward Drucker at the
Office of the Commissioners of Patents, with his Petition, on the 16th
November 1866.
I, EDWARD DRUCKER, of No. 97, Cheapside, in the City of London,
Merchant, do hereby declare the nature of the said Invention for "AN IN-
PROVED COMBINED PUNCHING AND EYELET MACHINE," a communication, to be as
follows:-
This Invention consists chiefly in the peculiar arrangement of the punches
and dies employed in the said machine, in the mode of operating the same,
and in the construction and arrangement of an adjustable gauge employed in
combination with the said punches and dies for regulating the distance
between the eyelet holes. The frame or bracket which carries the punches,
dies, and other parts of the machine is made of cast iron or other suitable
metal, and is furnished with jaws and a pinching screw, or other similar
device by which the machine can be firmly secured upon the edge of a table
or bench. On the upper part of this frame a projection is formed, into which

page_text: a metal tube is secured. The end of the said tube extends below the surface
of this projection, and carries a hollow steel punch, the said punch being
screwed in or otherwise secured to the metal tube. A socket or barrel is
forined upon the frame in a line with the metal tube and hollow punch. The
said frame is so formed as to leave a space or opening between the end of the
said tube and the socket or barrel to allow the work or material in which the
holes are to be formed to be brought into the required position. A hollow
rod or spindle is fitted to slide freely in the said socket, and inside this hollow
rod or spindle another rod is fitted to slide. A solid steel punch is secured in
the inner rod at the end opposite to the hollow punch, and the corresponding
end of the outer rod carries a hollow steel die which is fitted to slide over the
said punches. The two rods project at their other end beyond the socket in
which they slide. An excentric or cam is fitted between two jaws exactly
over the end of the said rods; this excentric is formed with projections
which are fitted and arranged to work in contact with the end of the outer
sliding rod carrying the hollow die. The cam also carries an adjustable nose
piece formed and arranged to work in contact with the end of the inner rod,
which for convenience is made to extend beyond the outer rod; this nose
piece is adjusted to give the required motion to the inner rod and its punch
by a set screw tapped into the cam at the back of the said nose piece; this
set screw is secured in any required position by a spring catch whose end is
fitted to drop into holes formed in the head of the set screw. The sliding rods
. are kept in contact with the excentric or cam by spiral springs; the said
excentric is by preference provided with a lever, which may be operated by
hand, by a treadle, or by other suitable means; by means of this handle the
excentric is turned on its bearing and caused to operate the sliding rods. The
punch carried by the inner rod is thereby forced into contact with the fixed
hollow punch secured in the metal tube in the upper part of the bracket, and
forms a hole in the material placed between the two punches; the pieces of
the said material removed by the punches pass away through the hollow punch
and tube. The eyelets to be inserted are first placed upon the sliding punch,
the said punch being made to project beyond the die through which it slides;
the said. die and punch move forward together till the latter comes in contact
with the hollow fixed punch; the nose piéce on the excentric then having
'moved past the end of the inner sliding rod no further'motion is, communicated
to the sliding punch, while the projections on the said excentric still continue
'to act upon the outer sliding rod and its die till the latter is forced over the
'fixed hollow punch. By this means the holes are formed; and the eyelets are
forced into the work and clenched therein by the same operation. The gauge

page_text: for regulating the distance between the holes formed by the punches consists
of a pin or finger provided with means of adjustment. The said pin corre-
sponds in size with the punch which forms the said holes, and is supported
upon a small bracket attached to the frame of the machine and extending at
right angles therefrom. A longitudinal slot is formed in this bracket for the
shank of a pin or finger to slide in; this shank is formed excentric with
the said pin, and a further adjustment can be thereby obtained besides that
effected by moving this pin in its slot; the said pin is held in any required
position by a nut fitted on a screw formed on the shank. The required
distance between the holes being ascertained the pin or finger is placed at the
same distance from the centre of the punches; the first hole is then formed
and placed on the said pin or finger while the second hole is formed; this
being repeated, a uniform distance between all the holes is ensured.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Drucker in the Great Seal Patent Office on the
16th May 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
DRUCKER, of No. 97, Cheapside, in the City of London, Merchant, send
greeting..

page_text: Office within six calendar months next and immediately after the date of the
said Letters Patent.
'
NOW KNOW YE, that I, the said Edward Drucker, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following 5
statement, reference being had to the accompanying Drawings forming a part
of this Specification: :-
This Invention consists chiefly in the peculiar arrangement of the punches
and dies employed in the said machine for forming the holes and securing the
eyelets, in the mode of operating the same, and in the construction and 1
arrangement of an adjustable guage employed in combination with the said
punches and dies for regulating the distance between the eyelet holes.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a plan of the top of my improved machine; Figure 2 is a front
elevation of the same; Figure 3 is a side elevation of the said machine; and
Figure 4 is a section on the line x, x, Figure 1. Like letters indicate the
same parts in each of the Figures.
The frame or bracket A, which carries the punches, dies, and other parts of
the machine, is made of cast iron or other suitable metal, and is furnished
with jaws A¹ and a pinching screw B or other similar device by which the
machine can be firmly secured upon the edge of a table or bench. On the
upper projecting part of the frame A a boss A is formed, into which a metal
tube C is fitted; the said tube is provided with a shoulder C¹ and nut C³, and
is securely held thereby in the boss A. The end of the tube C extends below
the surface of this boss, and carries a hollow steel punch D; the latter is
formed with a shoulder D', which is well fitted to the lower end of the tube C,
and is preferably provided with a screw thread D³, by which it is firmly and
immovably secured in the metal tube C; the concave die b is formed on or
attached to this punch. The bore of the hollow punch D and tube C may be
made taper throughout, the size increasing from the lower end of the punch
to the top of the tube. A socket or barrel A³ is formed upon the frame A in
line with the metal tube C and hollow punch D; the said frame is so formed
as to leave a space or opening between the end of the said tube and the socket
or barrel A³ (as more clearly shown in Figure 3) to allow the work or
material in which the holes are to be formed to be brought into the required
position, and the neck a of the said frame must be made of suitable strength
>to withstand the force exerted in punching the holes and securing the eyelets
therein. A hollow rod or spindle F is fitted to slide freely in the socket A³;

page_text: inside the hollow rod or spindle F another rod G is fitted to slide. A solid
steel punch H is secured in the inner rod G at the end opposite to the hollow
punch D, and the corresponding end of the outer rod carries a hollow steel
die I, which is fitted to slide over the punches D and H. The die I is screwed
or otherwise firmly secured to the rod F, or may be made in one piece with
the same.
The dies 6 and I are made concave to give the proper form to the
eyelets compressed between them; the two rods F and G project at the lower
end beyond the socket A³, in which they slide. An excentric or cam J is
fitted to work freely upon the pin or stud j between the two jaws A* exactly
opposite the end of the rods F and G; this cam is formed with projections J³,'
which are fitted and arranged to work in contact with the end of the outer
sliding rod F carrying the hollow die I. The cam J also carries an adjustable
nose piece J formed and arranged to work in contact with the end of the
inner rod G, which for convenience is made to extend beyond the end of the
outer rod F; this nose piece is adjusted to give the required motion to
the inner rod G and punch H by a set screw K, which is tapped into the back
of the cam J. The screw K is provided with a head K', whose edge is milled
or roughened to facilitate the turning of the said screw to adjust the nose'
piece J; the said nose piece is held in any required position by a spring
catch L, which is fitted and arranged to drop into holes k formed in the
head K of the set screw K.; the screw K is also held by the jam nut K³,
which when the nose piece has been properly adjusted is screwed tightly
against the back of the cam J, as shewn in Figure 4. The sliding rod F is
formed with the shoulder F, and is kept in contact with the cam J by the
pressure of the spiral spring N, which bears against the said shoulder and the
upper end of the interior of the barrel A", and a similar spring N¹ is employed
to keep the rod G in contact with the nose piece J³. The cam J is, by pre-
ference, provided with a lever or handle O which may be operated by hand,
by a treaddle, or other suitable means; the said handle is provided with the
stop O¹, which is arranged to come in contact with the side of the frame A:
By moving this handle downward the cam J is caused to act upon the
sitting rods F and G; the punch. H, carried by the inner rod G, is thereby
forced into contact with the fixed hollow punch D secured in the metal
tube C, and forms a hole in the material introduced between the two punches
D and H, the portions of the said material removed by the said punches
pass away through the interior of the hollow punch D and tube C. The
eyelets to be inserted are first placed upon the sliding punch H which when
the handle is raised projects up through the die I, as shown in Figure 2. The
handle when released is forced into this position by the spiral springs N, N'..

page_text: The die I and punch H move forward together till the latter comes in contact·
with the bollow fixed punch D. The nose piece J' which operates the punch
H, then having moved past the end of the inner sliding rod G which carries
the said punch, no further motion is communicated to the latter. The pro-
jections Jon the cam J, however, still continue to act upon the outer.
sliding rod F till the die I carried by the same is forced over the end of the
fixed hollow punch D, and into contact with the die b, as shown in Figure 4;
by this means the holes are formed and the eyelets are forced into the work
and clenched or secured therein by one operation or movement of the handle
or lever O. The gauge for regulating the distance betwen the holes formed
by the punches D and H consists of a pin or finger P corresponding in size
with the said holes, and provided with means of adjustment; the said pin is
supported upon a small bracket Q which is attached to the frame A, and
extends laterally at right angles therefrom, the pin P being parallel with the
punches D and H. A longitudinal aperture or slot q is formed in. the
bracket for the shank p of the pin or stud P to slide in; this shank is
arranged excentrically with the pin P, and a further adjustment of the gauge
can be thereby obtained, besides that effected by moving the pin P in the
bracket; the said pin is held in any required position by a nut R which
fits the screw thread formed on the end of the shank p. A portion of the
shank is made to fit the slot q in such manner as to slide freely therein, but
cannot be turned round till the nut R is unscrewed. The required distance
between the holes being ascertained the pin or finger P is placed at the same
distance from the centre of the punches D and H; the first hole is then
punched and placed on the pin or finger P, while the second hole is formed;
this adjustment being repeated for every hole, the correct distance between all
the holes is insured.
Having thus fully described the said Invention, as communicated to me by
my foreign correspondent, and shown how the same may be conveniently and
advantageously carried into practice, 1 claim,-
First, the punches D and H and dies 6 and I combined, arranged, and
operating for the purposes, and substantially in the manner set forth.
Second, the cam J with the projections J', and adjustable nose piece J³ for
imparting the required movements to the punch H and die I, constructed and
operating substantially in the manner set forth.
Third, the employment, in combination with the said punches, of the
gauge pin P'fitted to slide and adjust in the bracket Q, for the purpose and
substantially in the manner set forth.
Fourth, the frame A, punches D and H, dies 6 and
rods F and G,

page_text: cam J, and adjustable gauge P, combined and arranged substantially as and
for the purposes set forth.
In witness whereof, I, the said Edward Drucker, have hereunto set
my hand and seal, this Fifteenth day of May, in the year of our
Lord One thousand eight hundred and' sixty-seven.
EDWARD DRUCKER. (L.S.)
