Improvements in or applicable to Blocking, Embossing, and Cutting
Presses.
I, NATHANIEL JOHN HILL, Junior of Union Buildings, Leather Lane, in the
County of London, Engineer, do hereby declare the nature of this invention and
in what mauner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to certain improvements in or applicable to blocking and
embossing presses, the improvements having special reference to the means of
changing the press-stem from type-high to block-high, and vice versa; and to the
means of actuating the sliding table carrying the card to and from between the
press-stem and the press-head.
The invention is illustrated on the accompanying drawings; in which,
Fig. 1, represents a side elevation of the press with the press stem set
block-high.
Fig. 2, represents a front view thereof, and
Figs. 3 to 5, represent partial side elevations illustrating different positions of
the parts of the press.
A, represents a base-plate from which rises a standard B, carrying a heater-
box C, and a guide D, for the press-stem E, which is adapted to have vertical
movements therein, and requires, as aforesaid, to be changed as occasion may
require from type-high to block-high, and vice-versa, which is effected according to
the present improvements as hereinafter described; the press stem also carrying a
table F, which requires to be slid to and from between the press-stem and the
press-head, which is ordinarily done by hand, but is effected automatically and at
the proper times according to the present improvements as also hereinafter
described.
At its lower end, the press stem E, is recessed at e', and adapted to receive an
adjustable block e, the lower end of which is recessed at e³, and adapted to receive
an adjustable tumbler G, which is formed with two seatings g', g, at a distance
apart equal to the desired change of height of the press-stem.
The seatings gg, of the tumbler are respectively adapted (ride Figs. 1 and 5,)
to rest on a cam ', projecting from an axle H, which is centred in a bearing a¹,
rising from the bed plate. The axle H, has keyed or pinned to its other end a
handle by the movements of which and the connecting means described, the
vertical movements of the press-stem are thus effected, the extent of movement of
the handle being limited by stops h³, a².
'
Any finenese of adjustment of the press-stem required by any extra thinness or
thickness of the card being blocked or embossed, or the like, may be made by a
wedge I, bearing between the block e, and the top of the recess e, in the stem
(vide Fig. 4) the wedge being operated by a screw i, engaging in a collar bearing it;
secured as at, to the press-stem.
I also cause the table F, to be operated from the axle H, so as to bring the
table under the press-head in the beginning of the upward movement of the press-
stem by means of a lever J, which is centred at j, in bearings b rising from the
standard, the lever having a shorter arm, which is operated by a crank-pin.h*,
projecting from the end of the axle H, and a longer arm 3, which is slotted at j',
the slot engaging with a pin f', projecting from one side of the table, vide Figs. 1
and 2.
The table F, is fitted with slide-guides, which engage with other slide-guides e*,
cocuradite on muinating fr
the head of the atom and is also connected by a

page_text: spring or springs, to said head, and is provided with suitable stopping details.*
to ensure correct register, and is further, as aforesaid, connected by the pin 1, to
the slotted end of the lever J.
The operation of the apparatus is as follows, The handle ³, in its normal
position (Fig. 1,) bears through the pin h, on the lever J, and so causes the
table F, to be kept in feeding position, and the press-stem is also supported in its
lowest position by the cam .
On pulling the handle, the lever J, at the beginning of the rising of the press-
stem, is gradually freed from the pressure of the pin 4, which allows the spring or
springs, to gradually slide the table along the slide-guides e, to. its proper
blocking position (where it is stopped by the details f) between the press-stem
and press-head (vide Fig. 3). The continuation of the pull on the handle then,
through the tumbler G, completes the raising of the press-stem (vide Fig. 4) and
effects the desired blocking, embossing or cutting operation.
On returning the handle, the parts are all caused to resume the positions indicated
in Fig. 1.
When required to change the height of the stem as aforesaid, all that has to be
done is to raise the stem sufficiently to be able to shift and while shifting the
tumbler G, so that its other seating may bear on the cam, vide Fig. 5.
Instead of using the spring f³, for operating the table as aforesaid, it may be so
operated by hand, or it may be operated in both directions by the lever J, by
slotting the shorter arm of the latter and engaging the pin A, in such slot.
If the press is required to be utilized for cutting purposes, a still further increase
of space between the table and the press top will be required, for which provision
will be made in the fixed parts of the press, and the adjustment of which further
increase of space can be effected by providing the tumbler with a third seating
in like manner as aforesaid, or by providing a separate tumbler.
Having now particularly described and ascertained the nature of the said
inventica, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The hereinbefore described improved means of changing the press-stem from
type-high to block-high or for cutting, and vice versa.
2. The hereinbefore described means of automatically effecting the sliding move-
ments of the card-carrying table to and from between or from between the press
stem and the press head.
3. The improved blocking, embossing or cutting press herein before described
with reference to the accompanying drawings.
