PROVISIONAL SPECIFICATION.
Improvements in Machines applicable for Embossing and Printing
Paper and the like.
We, EDWIN BOTTOMLEY and FREDERIC BOTTOMLEY, both of Edward Street,
Bradford, in the County of York, Printers, do hereby declare the nature of this
invention to be as follows;-
-
This invention has for its object, the construction of a machine suitable for
embossing and printing on the platen principle, by so arranging the operating
mechanism that two platen plates or blocks may be operated from the same shaft,
in such a manner that, a direct pull on each platen is obtained, and to so mount
the platens that, they are tilted for receiving and removal of the paper or the
like and brought into parallel contact with the type or the like without the
intervention of cams.
In carrying out our object, we mount upon a suitable frame, a shaft having a
disc or crank at each end rotated in any convenient manner.
The machine may be arranged to have two platen blocks, or only one operated
from the same cranks. When the machine is arranged with two platen blocks,
cach block is connected by rods to the cranks, one rod on each side of each block,
which are mounted upon rocking arms arranged in such a manner that, by the
movement of the cranks, the platens are tilted into position for receiving the
paper to be embossed or printed, and on the continued rotation of the cranks,
they are alternately brought into parallel contact with the embossing or type
bed, at a time when the platen is moving slowly and the pull at its maximum,
immediately before the reversal in the movement of the platens.
The inking of the embossing or type bed, is accomplished by pivoted levers
coupled to the before mentioned rocking arms, the levers being arranged with
bars carrying the inking rollers, which are caused to pass over the surface of the
embossing or type bed at each revolution of the cranks, the necessary pressure
being regulated by springs and the ink obtained from any well known source.
The machine may be made single by making the rocking arms shorter, and
dispensing with the platen block and connecting rods for operating same on
one side of the machine.

We, EDWIN BOTTOMLEY and FREDERIC BOTTOMLEY, both of Edward Street,
Bradford, in the County of York, Printers, do hereby declare the nature of this
TD Q71

page_text: invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:
-
This invention has for its object; the construction of a machine suitable for
embossing and printing on the platen principle, by arranging the operating
mechanism that, a direct pull is obtained on the movable platen at a time when
the greatest pressure is required; and to so mount the movable platen, that it is
tilted for receiving and for the removal of the paper or the like to be printed
or embossed, and brought into parallel contact with the type or the like secured
to the fixed platen without the intervention of cams or curved paths now in
common use for placing the movable platen in the various positions required.
In describing our invention in detail reference is made to the accompanying
sheet of drawings, in which Fig. 1 represents an end elevation of a machine
constructed according to our invention, in which one of the end frames is removed
in order to more clearly show the mechanism of the machine, and
Fig. 2 is a front view of same without the ordinary paper stand which is
removed for more clearly showing the machine.
Like letters indicate like parts where they appear.
The end frames A, of the machine support the main shaft B, driven in any con-
venient manner, and on the shaft B, is a pinion C, gearing with spur wheel D, secured
on shaft E, carried by the said end frames, and on each end of the said shaft
is secured a crank or disc F, the pin S, of each disc being connected by a rod G,
to the ordinary eccentric shaft H, of the movable platen J.
The movable pláten J, is secured to one or more long rocking arms K, mounted
on a shaft L, supported by the end frames A, near to the bottom of same, in order
to obtain length and thereby reduce the curvature of motion of the movable
platen J. The said arms are extended beyond the shaft L, for the reception of
another movable. platen as hereinafter described or arranged for the reception
of a weight W, as shown, for balancing the movable platen J, which is made
adjustable, in relation to the face of the fixed platen M, in the ordinary manner.
The type or embossing characters are secured to the fixed platen M, and the
inking of the same is accomplished by the rollers N, mounted on movable bars O,
supported by the pivotted levers P, P, coupled to the before mentioned rocking
arms by rods Q, Q, so that by the rocking of the arms K, the pivotted levers P, P,
oscillate on their supports, causing the inking rollers N, to pass over the em-
bossing or type bed of the fixed platen M, the said rollers continuing their course,
pass over the rotating inking roller R, for receiving a supply of ink, transmitted
to the said roller from the intermittent rotating roller R', by the roller R², mounted
on oscillating levers T, operated by a suitable cam through the lever V, and rod Y.
The inking rollers N, return to their original position before the next impression
is made on the paper or the like supported by the movable platen J, in the
ordinary manner.
By mounting the movable platen J, on the long rocking arm or arms K,
and making the said platen adjustable on the rocking arm or arms, the face of
the platen J, is more readily brought into parallel contact, that is to say, the
top and bottom of the platen J, are more readily adjusted so as to come into
contact with the embossing or type bed of the fixed platen M, at the time, when
the platen J, is moving slowly, and the pull is at its maximum immediately
before and during the reversal of the stroke; thus making the necessary impression
on the paper or the like.
By making the movable platen J, adjustable in relation to the fixed platen M,
the machine is applicable for embossing purposes, the necessary pressure between
the two platens being obtained just before and during the reversal of the stroke,
when the platen J, is travelling at its slowest rate.
It will be obvious that by extending the crank or disc pins S, to a length
sufficient for receiving another connecting rod such as G, at each side, a duplicate
machine to that already described may be constructed and operated by extending

page_text: the end frames A, so as to receive two platens and additional inking device such
as before described, the movable platens such as shown on the drawings at J,
are in this case mounted, one at each end of a rocking arm or arms K, one movable
platen balancing the other, thereby dispensing with the balance weight W,
before described.
•
The movable platens are both tilted into position for receiving the paper to be
embossed or printed in the same manner, and by the continuous motion of the
cranks or discs F, the movable platens are alternately brought into contact
with the respective embossing or type beds of the fixed platens.
Having now particularly described and ascertained the nature of this our
invention, and in what manner the same is to be performed, we declare that what
we claim is―
In a printing or embossing machine constructed as hereinbefore described,
comprising rotating discs B, operating rocking arms K, and a movable platen or
platens J, inking rollers N, mounted on movable bars O, supported by pivoted
levers P, operated by rods Q, all arranged substantially in the manner described
and for the purpose specified.
