I, FERDINAND BOSSHARDT of the firm of Bosshardt & Grant Mechanical and
Consulting Engineers & Patent Solicitors of 24 & 32 Bulls Head Exchange
Chambers Market Place Manchester in the County of Lancaster, do hereby declare
the nature of my invention for "IMPROVEMENTS IN APPARATUS OR MACHINERY
FOR IMPRESSING DESIGNS UPON PRINTING AND EMBOSSING ROLLERS
"which has
been communicated to me from abroad by Henri Carliez of Deville-les-Rouen in
the Republic of France to be as follows:-
My invention relates to improvements in apparatus or machines which are
employed for punching or embossing patterns upon metallic rollers or cylinders and
has for its object to effect the punching or embossing of patterns either from the
side, below or from the top of such cylinders or rollers and to facilitate the intensity
of depth by regulating the blow of the hammer working the punch.
The apparatus consists of a frame between which a weight is arranged to slide
up and down in a vertical direction and strike a spindle which actuates a lever
provided with a suitable punch and being pressed against the spindle by means of
a spring.
The said lever may be formed in such a manner as to enable the punch to
produce the design either from the side, bottom or top of the roller or cylinder.
The said weight is gripped by and connected to a slide and lifted to a certain
height and when coming into contact with a projection piece above will be
disconnected and discharged and caused to fall onto the spindle thus actuating the
punch lever.
The said projection is made adjustable in order that the travel of the weight may
be varied which will cause the punch to impress the pattern on the cylinder more
or less. Any suitable number of such apparatus may be fixed to a pantograph
frame and worked by a foot treadle.

sulting Engineers and Patent Solicitors of 24 & 32 Bulls Head Exchange Chambers
Market Place Manchester in the County of Lancaster, do hereby declare the nature
of my Invention for IMPROVEMENTS IN APPARATUS OR MACHINERY FOR IMPRESSING
DESIGNS UPON PRINTING AND EMBOSSING ROLLERS which has been communicated
to me from abroad by Henri Carlioz of Deville-les-Rouens, in the Republic of
France, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates to improvements in apparatus or machines which are
employed for punching or embossing patterns upon metallic rollers or cylinders and
has for its object to effect the punching or embossing of patterns either from the
side, below, or from the top on such cylinders or rollers and to facilitate the
intensity of dopth by regulating the blow of the hammer working the punch. And
in order that my invention may be better understood I have caused to be appended
hereunto two sheets of drawings marked with letters of reference corresponding
'letters indicating like parts in the various figures.
Fig. 1 represents a side elevation showing the arrangement of punch, for
punching or embossing pattern on cylinder or roller from below.
Fig 2 is also a side elevation, but showing the punch arranged above the cylinder
or roller.
Fig 3 is an end view and Fig 4. a side view showing a number of such apparatus
connected together and worked by means of a treddle simultaneously.
The apparatus consists of a frame g between which a weight M is arranged to
slide up and down in a vertical direction and strike a spindle G which when the
cylinder or roller is to be operated upon from below actuates a lever L provided with
a suitable punch P and being pressed against the spindle G by means of a spring R
sco Fig 1. The said lever L may be formed in such a manuer as to enable the
punch P to produce the design either from the side bottom or top of the roller or
cylinder or the said punch may be connected direct onto the spring R see Fig 2.
The weight M is provided at its top with a button t which is gripped by a spring
clip v connected to a slide m and when lifted to a certain height will come into
contact with a projection b fixed at the frame g. above the slide m which causes the
spring clip to open out, disconnect-and discharge the weight M. The latter
then falls onto the spindle G and thus actuating the punch lever L see Fig 1 or
spring R see Fig 2. The projection b is made adjustable in order that the travel of
the weight M may be varied which will cause the punch P to impress the designs
or patterns onto the cylinder or roller more or less. When working a number of
such apparatus simultaneously see Figs 3 and 4 1 make the same movable ou tho
pontagraph frame or bed V and work the punches conjointly by means of a foot
treddle A.
The cords E running over pulleys F and rotating on the shafts K carried by the
arms O. and N of the pentagraph frame are connected on one end to the slide m
and on the other end to the rod D carried by the levers C provided with studs,
rocking in the arm O. One of the said studs has the lover C₁ fixed thereto which
is brought into connection with the treddle A by means of the bent lever B. and
compounded levers C³, C, C and rod C. Any number of punching apparatus
may be used and worked from ouo treddle, with greater ease and regularity by an
unskilled workman,

page_text: Instead of obtaining the design to be impressed onto the rollers from zinc plates
or sheets, the latter are substituted by means of gelatine or other transparent
material. These plates are on the front surface provided with pricks or indentations
formed a suitable distanco apart from each other and are placed direct onto the
designs or original drawings, thus preventing the drawings from being spoiled by
the pointer of the pentagraph when working on it and saving the cost of the
production of the designs on the zinc plates. Several different distinct impressions
can be obtained at the same time and upon the same roller by simply changing the
gelatine sheets. The use of the latter is of great advantage and saving and is
particularly applicable for furniture designs.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed I declare that what
I claim is
First. The lever L provided with the punch P in combination with the spindle G
and spring R arranged for punching the designs onto the roller or cylinder either
from the top, bottom or side of the said roller or cylinder for the purpose specified,
substantially as described and illustrated in the annexed drawing.
Second, Connecting a number of such apparatus to a pantograph frame and
working the same simultaneously by means of a foot treddle as described and
illustrated for the purpose set forth.
