WALTER ALFRED BARLOW, of 6, St. Paul's Churchyard, London, Patent Agent
and Engineer. "A NEW OR IMPROVED MACHINE FOR EMBOSSING AND PREPARING
PAPER OR OTHER FABRIC." A communication from abroad by Carl Louis Nagel,
of Brooklyn, in the County of Kings, and State of New York, United States of
America.
The object of this Invention is to produce a machine by means whereof paper,
leather, or other fabric can be embossed in strips and sheets with ornamental designs,
and also perforated to increase the effect of the embossing process, all at ome opera-
tion; and the Invention consists particularly in combining in one machine, and
securing to one reciprocating cross head an embossing die and perforating plungers,
so that the two operations of embossing and perforating may be simultaneously
carried on to properly affect the strip of paper.
The Invention also consists in various details of construction of the parts which
make up the machine.
The frame of the machine is of metal or other suitable material, of proper size
and strength to enable it to accommodate the parts of the mechanism, and to pro-
perly support the same during operation. In the upper part of this frame is hung
the driving shaft, to which rotary motion is imparted by suitable mechanism. From
cranks formed on this driving shaft is suspended a cross head, to which, by means
of said cranks, reciprocating motion in a vertical direction is iniparted. The ends

page_text: of the cross head are guided in grooves that are formed on the uprights or posts of
the frame.
The connection between the reciprocating cross head and the crank shaft is as
follows:-
-A plate is, by links that embrace cylindrical portions of the cross head,
united to the latter as by a joint, so that the plate may vibrate on the hinges thus
formed in travelling up and down with the cross head. A similar plate is, by
similar links, suspended from the crank shaft, and capable therefore of vibrating
thereon, and the two plates where they come together are united and rigidly con-
nected by screws. Thus a flexible connection is formed, which, however, by having
the same in two parts, permits of adjustment. This adjustment is effected by
wedges which are introduced between two plates, and which, at their larger
ends that project from and beyond said plates, carry screw projections, upon which
pinions are mounted. The two pinions of the two wedges gear into a toothed wheel,
and the screws fit proper nuts that are formed in the pinions, the outer ends of the
screws being supported and guided in brackets which connect with the flexible plate,
as may be desired.
Now, when it is desired to cause the cross head to descend to a greater depth; and
to define the embossing design more perfectly and sharply, it is only necessary, after
first loosening the connecting screws of the plate to turn the wheel, and thereby
screw the wedges further in between the plates, thereby separating them to a
certain extent, and increasing the distance between the crank shaft and the cross
head.
To the lower face of the cross head is attached by screws the die plate, which
plate however is readily removed by unfastening said screws. The die plate carries
along one face of the machine a suitable die, which has the positive design of the
embossing engraved on its lower surface. Along the other face of the machine, the
die plate carries a series of punches or perforating pins, properly arranged as to
shape and distance from one another, so that they will harmonize in their effect
with the design, which is produced by the embossing tools. Instead of making the
plate in one piece, it may be made in a series of pieces.
Below the cross head' and die plate is supported upon a thick horizontal bar or
plate, which constitutes part of the frame, the bed plate which supports beneath the
die a counter die, and beneath the punches a perforated plate. At a distance above
the counter die and perforated plate, there is also secured a stripper plate, which is
perforated to admit the punches, substantially in the same manner as the plate is
perforated; and which is also perforated to admit the entire die.
The paper, to be embossed and perforated is fed through the machine between the
stripper plate and the bed plate, so as to be in contact with the counter die and
with the perforated plate. It is fed in so as to first be affected by the embossing,
and next by the perforating mechanism. The paper having been properly introduced
beneath the stripper plate, the cross head is brought down, so as to force the die
against the paper, crowding the latter into the cavities. of the counter die, and
thereby imparting to it the desired embossed form and ornamentations. The paper
thus embossed being further fed forward is next perforated at the desired places by
the descending punches, and at the same time another portion of the paper is
embossed, and so forth until the entire length of the paper has been properly
treated.
The punches, counter die, stripper plate, and perforated plate may of course be
readily removed to permit different designs to be formed by the same machine, and
for this reason I prefer to make that portion of the stripper plate which is perforated
to admit the punches, separate from the other portion of the stripper plate, which
merely admits the die, as it will be more frequently necessary to remove the per-
forated portion of the stripper plate for different designs than that portion which is
above the counter die.
For feeding the paper, two pairs of rollers are employed. These rollers receive
their motion by gear wheels from a toothed wheel upon whose arbor. a ratchet
wheel is mounted, which receives intermittent rotary motion by a pawl from a

page_text: vibrating lever. This lever is moved by a crank of the driving shaft, and is held
against said crank by a spring. Whenever the crank strikes the vibrating
lever, said lever will impart motion to the ratchet wheel and also to the feed
rollers.
For varying the degree of feed the crank is made extensible, that is, it is con-
structed of two parts, of which one is slotted and connected to the other by a screw.
This enables me to feed the paper with greater or less speed, according to the nature
of the design to be produced upon it.
It will be observed that I first emboss the paper, and then punch out portions to
perforate the same; the process, as far as that is concerned, may be reversed, although
I prefer to first emboss and then perforate, because I thereby obtain for the per-
forating punches a less laborious movement, as the parts to be punched out are
first depressed and reducing in thickness, by the embossing apparatus, and also
because the paper if first perforated would be likely to be drawn out of shape by
the embossing apparatus.
I also keep the embossing tools clear of the waste produced by the punches, by
first embossing.

the said Walter Alfred Barlow in the Great Seal Patent Office on the 9th

WALTER ALFRED BARLOW, of 6, St. Paul's Churcbyard, London, Patent Agent
and Engineer. "A NEW OR IMPROVED MACHINE FOR EMBOSSING AND PREPARING
PAPER OR OTHER FABRIC." A communication from abroad by Carl Louis Nagel,

The object of this Invention is to produce a machine, by means whereof paper,
leather, or other fabric can be embossed in strips and sheets with ornamental designs,
and also perforated to increase the effect of the embossing process, all at one opera-
tion; and the Invention consists particularly in combining in one machine and
securing to one reciprocating cross head an embossing die and perforating plungers,
so that the two operations of embossing and perforating may be simultaneously
carried on to properly affect the strip of paper.
The Invention also consists in various details of construction of the parts which
make up the machine, all as herein-after more fully described.
In the accompanying Drawings,
Fig. 1 is a front elevation of the improved embossing and perforating machine;
Fig. 2, an end view of the same.
Fig. 3, a vertical cross section thereof on the line c, c, of Fig. 1.
Fig. 4 is a detailed plan view of a strip of paper embossed and partly perforated
by the machine.
A is the frame of the machine; the same being made of metal or other suitable

page_text: material of proper size and strength to enable it to accommodate the parts of the
mechanism, and to properly support the same during operation. In the upper part
of this frame is hung the driving shaft B, to which rotary motion is imparted by
suitable mechanism. From the cranks a,'a, which are formed on this driving shaft,
is suspended a cross head c, to which, by means of these cranks, reciprocating motion
in a vertical direction is imparted. The ends of the cross head are guided in grooves
that are formed on the uprights or posts of the frame A.
The connection between the reciprocating cross head C and the crank shaft B is
as follows:-A plate D is by links b, b, that embrace cylindrical portions of the
cross head united to the latter as by a joint, so that the plate D may vibrate on
the hinges thus formed in travelling up and down with the cross head. A similar
plate E is by similar links & suspended from the crank shaft, and capable therefore
of vibrating thereon, and the two plates D and E where they come together are
united and rigidly connected by screws e, of which the heads are indicated in Fig. 1.
Thus a flexible connection is formed,' which, however, by. having the same in two
parts D and E permits of adjustment. This adjustment is effected by wedges f
which are introduced between the two plates D and E, and which at their larger
ends that project from and beyond said plates carry screw projections g, upon which
pinions h are mounted, all as indicated in Figs. 1 and 3. The two pinions h, h, of
the two wedges gear into a toothed wheel F, and the screws g fit proper nuts that
are formed in the pinions, the outer ends of the screws being supported and guided
in brackets, which connect with the plate D or E, as may be desired.
Now, when it is desired to cause the cross head to descend to a greater depth,
and to define the embossing design more perfectly and sharply, it is only necessary,
after first loosening the screws e, to turn the wheel F, and thereby screw the wedges
further in between the plates D and E, thereby separating them to a certain extent,
and increasing the distance between the crank shaft B and the cross head C.
-
To the lower face of the cross head C is attached by screws j,j, the die plate G,
which plate however is readily removed by unfastening said screws j, j. The die
plate G carries along one face of the machine a suitable die K, which has the positive
design of the embossing engraved on its lower surface. Along the other face of the
machine the die plate G carries a series of punches or perforating pins 7, properly
arranged as to shape and distance from one another, so that they will harmonize
in their effect with the design which is produced by the embossing tools.
Instead of making the plate G in one piece, it may be made in a series of pieces.
Below, the cross head and die plate is supported upon a thick horizontal bar or
plate m, which constitutes part of the frame A, the bed plate H which supports
beneath the die K a counter die n, and beneath the punches a perforated plate J.
At a distance above the counter die and perforated plate J there is also secured a
stripper plate I, which is perforated to admit the punches L, substantially in the
same manner as the plate J is perforated, and which is also perforated to admit the
entire die k.
The paper to be embossed and perforated is fed through the machine between the
stripper plate and the bed plate H, so as to be in contact with the counter die and
with the plate J. It is fed in the direction indicated by the arrow in Fig. 3, so as
to first be affected by the embossing and next by the perforating mechanism. The
paper baving been properly introduced beneath the stripper plate, the cross head is
brought down, so as to force the die k against the paper, crowding the latter into
the cavities of the counter die, and thereby imparting to it the desired embossed
form and ornamentation. The paper thus embossed being further fed forward is
next perforated at the desired places by the descending punches, and at the same
time another portion of the paper is embossed, and so forth until the entire length
of the paper has been properly treated.
The punches, counter die, stripper plate, and perforated plate J may of course
be readily removed to permit different designs to be formed by the same machine,
and for this reason it is preferred to make that portion of the stripper plate which
is perforated to admit 'the punches separate from the other portion of the stripper

page_text: plate which merely admits the die k, as it will be more frequently necessary to
remove the perforated portion of the stripper plate for different designs than that
portion which is above the counter die.
For feeding the paper, two pairs of rollers o; o, and p, p, are employed, as clearly
shown in Fig. 3. These rollers receive their motion by gear wheels 9, 9, shown in
Fig. 2, from a toothed wheel r, upon whose arbor a ratchet wheel 8 is mounted,
which receives intermittant rotary motion by a pawl t from a vibrating lever L.
This lever is moved by a crank u of the driving shaft B, and is held against said
crank by a spring v. Whenever the crank u strikes the lever L, said lever will
impart motion to the ratchet wheel, and also to the feed rollers.
For varying the degree of feed the crank u is made extensible, that is, it is con-
structed of two parts, of which one is slotted and connected to the other by a screw,
as clearly shown in Fig. 2. This enables the feed of the paper to be effected
with greater or less speed, according to the nature of the design to be produced
upon it.
It will be observed that the paper is first embossed, and then portions are punched
out to perforate the same, as indicated in Fig. 4; the process as far as that is con-
cerned may be reversed, although it is preferred to first emboss and then perforate,
because thereby is obtained for the perforating punches a less labourious movement,
as the parts to be punched out are first depressed and reduced in thickness by the
embossing apparatus, and also because the paper, if first perforated, would be likely
to be drawn out of shape by the embossing apparatus.
The embossing tools are also kept clear of the waste produced by the punches by
first embossing.
Having now described the nature and particulars of the said Invention, I
claim,―
First. In a machine for embossing and perforating paper, the combination of the
reciprocating cross head C with the die k and punches attached thereto, and with
