COMPLETE SPECIFICATION.
Improvements in Embossing Presses.
We, FREDERICK BADDELEY and WILLIAM JOHN REYNOLDS, both of
19 and 20 Old Bailey, in the City of London, Die Sinkers, do hereby declare the
nature of our said invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
Whereas, in presses used for embossing or stamping designs upon paper, card-
board and analogous materials, it has been the practice to fit the die or counterpart
to a plunger working in vertical guides, and raised, after being depressed by a spring
or springs. In order that the die and counterpart may meet with accuracy, it is
necessary, in such presses, to fit the plungers carefully; and when slackness has
arisen from wear or slight defects in the workmanship, the embossing is performed
inefficiently.
And whereas, the die or counterpart has, in some cases, been fitted to a hinged
lever; but any slackness at the hinge or axis on which the lever works also causes
a great want of precision in the meeting of the die and counterpart.
Now the object of our invention is to manufacture embossing presses in such a
manner as to simplify and reduce the number of working parts, and at the same
time to render the presses more efficient in use.
And in order that our said invention may be particularly described and
ascertained, reference is hereby maile to the accompanying drawing in which a
lever embossing press, constructed according to our invention, is shewn.
a is the body of the press. b is a flat steel or other metal spring of a suitable
form, width, thickness and elasticity, so that while it is sufficiently flexible to allow
the die to approach the counterpart, the spring will not yield in any other direction.
One end of the spring b is rigidly attached at c to the press by means of screws,
rivets or otherwise. To the other end of the spring b we fit a die or counterpart d,
the corresponding counterpart or die e being attached to base a¹ of the press a, in
such a manner that when pressure is applied to the cam lever f, and the spring b
being thereby forced downward, the die d and counterpart e exactly coincide.
Although we have shewn and described a form of lever embossing press, it will
be understood that our improvements are equally applicable to other forms of
presses where screws and other means are employed to provide the necessary
pressure; the essential part of this invention being the attachment of the die or
counterpart to a spring which is flexible in one direction only, and thereby
dispensing with guides, rocking bars and other means of guiding the die or
counterpart into their proper positions, and also rendering it possible to cheapen
the manufacture.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In an embossing press, the application and use of a flat spring b, rigidly
attached to the body of the press at one end c, and having a die or counterpart d
fitted at the other end, substantially as and for the purposes herein before described
and illustrated by the drawing.
2. The general construction combination and arrangement of the several and

page_text: respective parts, together constituting our improvements in embossing presses,
substantially as herein before described and illustrated by the drawing.
