"I, CHARLES WILSDON, of 24, Whitfield Street, Tottenham Court Road, in the
County of Middlesex, Die Sinker and Manufacturing Stationer, do hereby de-
clare the nature of this invention to be as follows:--
The invention relates to improvements in or connected with embossing
stamps or dies.
It is frequently required to emboss note-paper or other material with initials
or lettering in ornamental or plain characters, and this has heretofore been
accomplished by engraving a special die, and this is a work of time even in a
city where the engraving is executed, but when as frequently happens the order
is given to a country stationer who is unable to execute it himself and there-
fore forwards it to a die sinker probably at some distance the delay is much
increased, and a considerable time must necessarily elapse between the receipt
of the order and its execution.
Now the object of the present invention is by a simple contrivance to enable
a country stationer for example to himself construct an embossing die having
the required initials or letters so that he can do the work upon his own pre-
mises, and execute the order with great expedition.
In carrying the invention into effect a number of rectangular. steel type
blocks, are employed, upon one side or face of each of which is engraved a
different letter of any suitable character and a number of such sets of type
blocks each engraved with letters of different character may be kept at hand in
readiness for use and these type blocks are adapted to be set up and clamped in
a holder as hereinafter described.
In connection with these type blocks is employed a holder or
"chuck" con-
sisting of a rectangular frame formed with a longitudinal opening therein and
provided with projecting ribs extending longitudinally of said opening on each
side from one end nearly to the other end thereof beyond which point by reason
of the absence of the ribs the opening is increased and constitutes a filling space
for the type blocks as hereinafter described.
The type blocks are each formed with a groove in its ends parallel with the
lettered face and said type blocks are adapted to be inserted in the filling open-
ing of the frame and then caused to engage by their grooves the projecting ribs
so that they may be slidden up to a stop in the frame and thus the required
combination of initials may be readily placed in position and in order to firmly
clamp the blocks therein during the embossing operation a set screw is pro-
vided at one end of the frame which impinges upon a filling or idle piece similar
to a type block and adapted to occupy a position at the end of the group of
blocks..
In order to cause the engraved faces of the type blocks to project beyond the
surface! of. the chuck or holder and the backs thereof to lie flush therewith the
ribs or projections of the chuck or holder are arranged to extend from the front
of the chuck to within such a distance of the back thereof as will enable the

page_text: flanges formed by the grooves in the ends of the type blocks and consequently
the latter to lie flush with the back of the chuck or holder.
When it is desired to employ sloping letters the type blocks are preferably
rhomboidal in form and in order to obtain a firm stop at the end of the frame a
blank tapered stop and filling piece are for that purpose slidden into place.
Or if desired the end of the frame bordering the opening may be formed in-
clined to accommodate inclined rhomboidal type blocks and a wedge like stop
piece may be fitted in at the end of the frame in order to accommodate rect-
angular type blocks when it is desired to fit the same up therewith.
In some cases the rectangular blocks may be engraved on four faces.
It will be obvious that the details of the device may be more or less varied
without departing from the spirit of the invention and it will also be understood
that any other suitable chuck or holder than that herein described may be
employed to clamp the type blocks in proper relation during the embossing
operation.
By the means herein before described the necessity for specially engraving a
die with the initials required to be embossed is obviated, and a die may in cases
of emergency be readily made up without the necessity for calling in skilled aid
whilst the resulting work will be equal to that produced by a specially
engraved die.

Improvements in or connected with Embossing Stamps or Dies.
I, CHARLES WILSDON, of 24, Whitfield Street, Tottenham Court Road, in the
County of Middlesex, Die Sinker and Manufacturing Stationer, do hereby de-
clare the nature of this invention and in what manner the same is to be per-
forined to be particularly described and ascertained in and by the following
statement:—
The invention relates to improvements in or connected with embossing
stamps or dies.
It is frequently required to emboss note paper or other material with initials
or lettering in ornamental or plain characters, and this has heretofore been
accomplished by engraving a special die, and this is a work of time even in a
city where the engraving is executed, but when as frequently happens the order
is given to a country stationer who is unable to execute it himself and there-
fore forwards it to a die sinker probably at some distance the delay is much
increased, and a considerable time must necessarily elapse between the receipt
of the order and its execution.
Now the object of the present invention is by a simple contrivance to enable
a country stationer for example to himself construct an embossing die having
the required initials or letters so that he can do the work upon his own pre-
mises, and execute the order with great expedition.
In carrying the invention into effect a number of rectangular steel type
blocks are employed, upon one side or face of each of which is engraved a
different letter of any suitable character and a number of such sets of type
blocks each engraved with letters of different character may be kept at hand in
readiness for use and these type blocks are adapted to be set up and clamped in
a holder as hereinafter described.

or chuck" cón-
In connection with these type blocks is employed a holder
sisting of a rectangular frame formed with a longitudinal opening therein and
provided with projecting ribs extending longitudinally of said opening on each
side from one end nearly to the other end thereof beyond which point by reason
of the absence of the ribs the opening is increased and constitutes a filling space
for the type blocks as hereinafter described.
The type blocks are each formed with a groove in its ends parallel with the
lettered face and said type blocks are adapted to be inserted in the filling open-
ing of the frame and then caused to engage by their grooves the projecting ribs
so that they may be slidden up to a stop in the frame and thus the required
combination of initials may be readily placed in position and in order to firmly
clamp the blocks therein during the embossing operation a set screw is pro-
vided at one end of the frame which impinges upon a filling or idle piece similar
to a type block and adapted to occupy a position at the end of the group of
blocks.
In order to cause the engraved faces of the type blocks to project beyond the
surface of the chuck or holder and the backs thereof to lie flush therewith the
ribs or projections of the chuck or holder are arranged to extend from the front
of the chuck to within such a distance of the back thereof as will enable the
flanges formed by the grooves in the ends of the type blocks and consequently
the latter to lie flush with the back of the chuck or holder.
When it is desired to employ sloping letters the type blocks are preferably
rhomboidal in form and in order to obtain a firm stop at the end of the frame
and a proper action of the clamping screw a blank tapered stop and filling piece
are for that purpose slidden into place.
Or if desired the end of the frame bordering the opening may be formed in-
clined to accommodate inclined rhomboidal type blocks and a wedge like stop
piece may be fitted in at the end of the frame in order to accommodate rect-
angular type blocks when it is desired to fit the same up therewith.
In some cases the rectangular blocks may be engraved on four faces.
It will be obvious that the details of the device may be more or less varied
without departing from the spirit of the invention and it will also be understood
that any other suitable chuck or holder than that herein described may be
employed to clamp the type blocks in proper relation during the embossing
operation.
And in order that the said invention may be more clearly understood and
readily carried into effect I will proceed aided by the accompanying drawings
more fully to describe the same.

In the several figures like parts are indicated by similar letters of reference.
Referring to Figures 1 to 10 a represents the rectangular steel type blocks
upon one side or face of each of which is engraved a different letter or sign of
any suitable character and these type blocks, a number of sets of which en-
graved with letters or signs of different character may be kept at hand in readi-
ness for use, are adapted to be set up and clamped in a holder or chuck" such
as in the manner hereinafter described.
The holder or chuck consists of a rectangular frame b formed with a longi-
tudinal opening 2 therein and provided with projecting ribs 6 extending
longitudinally of said opening on each side from one end nearly to the other
.end thereof beyond which point the area of the opening is increased and con-
stitutes a filling space or entrance for the type blocks a as hereinafter
described.
The type blocks a are each formed with a groove a¹ in its upper and lower
ends parallel with the lettered face and corresponding with the ribs of the
chuck or holder band said type blocks a are adapted to be inserted in the
frame b at the filling opening 62* and then moved laterally and caused to engage
by their grooves a¹ the projecting ribs of the frame 6 so that they may be
slidden up to the end of the frame which constitutes a stop or abutment thereto
and thus the required combination of initials or signs a may be readily placed
in the chuck or holder and in order to firmly clamp the type blocks a in
position during the embossing operation a filling or idle piece a² somewhat
similar to a type block is placed at the end of the group of blocks a and in
connection therewith a set or clamping screw e provided with a removable key c¹
is employed which screws through a threaded hole in the end of the chuck or
holder band impinges upon the filling or idle piece a².
In order to cause the engraved faces of the type blocks a to project beyond
the surface of the chuck or holder b and the backs thereof to lie flush therewith
the ribs or projections b¹ of the chuck are of less width than the frame band
are arranged to extend laterally from the front of the chuck or holder b to within
such a distance of the back thereof as will provide counter-sinks 61* for, and
enable, the flanges a formed by the grooves a¹ in the ends of the type
blocks a and consequently the latter to lie flush with the back of the chuck or
holder and project beyond the front thereof.
This may conveniently be accomplished by forming the ribs 6 originally of
the width of the frame band removing the parts not required by means of a
planing tool which of necessity leaves the channels in the line of cut at the
end of the frame.
Or as a modification of this device the ribs or projections might be formed
somewhat narrower and arranged centrally of the chuck or frame 6 and the
coacting grooves a¹ in the type blocks a might be arranged to correspond that
is out of the centre as will be readily understood.
The filling or idle piece a³ in order that its face may lie below the face of the
die formed by the group of type blocks a is whilst otherwise the same in con-
struction as said type blocks formed of a reduced depth as will be clearly seen
on reference to Figure 5 and the same principle is carried out with regard to
all filling and stop pieces hereinafter referred to.
In the example given at Figures 11 to 15 which illustrate a method of
employing sloping letters the type blocks a are preferably rhomboidal in form

page_text: as shown more particularly at Figures 12 and 13, and in order to obtain a firm
stop or abutment at the end of the frame b a blank filling or stop piece a in
the form of a right angle triangle is employed said stop piece being inclined on
one side thereof to the angle of the type blocks whilst a similar but inverted
filling piece is provided for the screw c to bear against and by these means
a chuck or holder 6 arranged for rectangular type blocks is enabled to accom-
modate rhomboidal type blocks having sloping letters.
In the example given at Figure 16 the device is substantially the same as
that lastly herein before shown and described but in this case the inclined loose
stop piece a is dispensed with and the necessary incline is formed at 6* upon
the end of the frame 6 bordering the opening in order to accommodate
rhomboidal type blocks.
In the example given at Figure 17 the frame of the chuck b is constructed
in a similar manner to that lastly herein before described but in order that
it may accommodate rectangular type blocks an inclined inverted loose stop
piece a is inserted in the frame band in this case the filling piece a² is rect-
angular in shape.
From the foregoing examples it will be seen that the chuck or holder may
indifferently be fitted up with either rectangular or rhomboidal type blocks
at will.
Although sloping letters have herein before been shown and described in con-
nection with inclined type blocks it will be obvious that they might although
perhaps not with equal advantage be formed upon rectangular type blocks.
In the example given at Figures 18 and 19 is illustrated a method of employ-
ing rectangular type blocks formed with multiple engraved faces.
In this case the type blocks a are formed with four faces of equal size and
the ends thereof are grooved in two directions at right angles to each other thus
leaving instead of two flanges a*, as herein before shown and described with
respect to the previous examples, four rectangular posts or studs a* which
fulfil the same office as the flanges but enable the type blocks a to be so
arranged with relation to the ribs or projections 61 of the chuck or holder b as
to present either of their four faces in the desired direction and thus a complete
alphabet may be comprised in a comparatively small number of type blocks.
In this case the ribs or projections 61 of the chuck or holder 6 and the co-
acting grooves a¹ of the type blocks a are formed somewhat narrower than in
the preceding examples in order to leave sufficient metal in the posts a¹* to
enable them to withstand the strain to which they are necessarily subjected in
the press.
When using an embossing die made up in this.manner it will be desirable to
protect the back faces of the type by means of a thickness of card, lead or the
like from possible injury whilst in the press.
It will be obvious that the details of the device may be otherwise more or
less varied without departing from the spirit of the invention and that other
signs may be substituted for letters of the alphabet and it will also be under-
stood that any other suitable chuck or holder than that herein before shown and
described may be employed to clamp the type blocks in proper relation during
the embossing operation.
.
By the means herein before described the necessity for specially engraving a
die with the initials required to be embossed is obviated and a die may in cases
of emergency be readily made up without the necessity for calling in skilled aid
whilst the resulting work will be equal to that produced by a specially
engraved die.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1 An essential part of an embossing stamp or die comprising a fount or

page_text: collection of independent type blocks adapted to be clamped in selected groups
in a chuck or holder substantially as herein shown and described.
2. An essential part of an embossing stamp or die comprising a fount.or
collection of independent type blocks formed with multiple engraved faces and.
adapted to be clamped in selected groups in a chuck or holder substantially, as
herein shown and described.
