"IMPROVEMENTS IN MACHINES OR APPARATUS FOR CUTTING LABELS WHICH
APPARATUS CAN BE EMPLOYED FOR BLOCKING "
This invention relates to improvements in machines employed for cutting
several thicknesses of paper at each stroke to produce labels and which can be
printed or plain also in employing the same apparatus for blocking instead of the
arming-press heretofore employed. For this purpose I construct a strong cast iron
bed plate on which I secure by bolts and nuts a frame having at a regulated
distance a table which may be cast with the frame or secured thereto; over the
table and at a given height is a strong bracket cast with the frame and this bracket
may be fitted with brass bushes through which works a strong hollow plunger; over
this bracket and also at a given distance is cast with the frame another strong bracket
which is also by preference fitted with brasses or bushed and through which works
the hollow plunger.
The top of the frame is made with plummer blocks fitted with brasses and caps,
in the brasses works a wrought iron shaft and the end of the shaft is made with an
eccentric in which is secured out of centre a stud or pin on which is fitted and
works the head of a connecting rod which is made at the other end with a jaw and
which is fitted and secured by a pin to the head of a stud secured in the bottom of
the hollow plunger and the plunger is made so as to allow a free action to the
connecting rod in the inside of the plunger.
On the other end of the top shaft is secured a spur wheel which is actuated by a
pinion secured on the driving shaft of the apparatus, and on the driving shaft is
secured a fly wheel and a fast and loose pulley to drive and stop the machine.
The bottom end of the plunger is cut with a screw on which is screwed a pressing
block, and the screw allows of setting the block according to the different heights
of the cutting punches and the block is secured when in position to the plunger by
set screws.
To cut the several thicknesses of paper and the labels either plain or printed, the
several thicknesses of paper are placed on the table and the cutting punch placed
s required; the pressing block is then secured at the required height and the
n

page_text: apparatus is started which on the down stroke of the plunger forces the cutting
punch through the several thicknesses of paper cutting out the labels either plain or
printed, on the return stoke of the plunger the machine is stopped and the labels
removed; the cutting punch is then again placed in position and the plunger
brought down.
For blocking I remove the pressing block and secure on the end of the plunger a
hollow box; the front plate of the box is made with, two, three or more openings
through which are passed gas pipes bored with a series of small holes, the gas pipes
are secured to an elbow and T pieces, and one end is connected to a gas supply
pipe.
The underside of the hollow box is fitted with a moveable plate on which are
placed and fixed the letters or devices for blocking. The gas being turned on
passes in the gas pipes and through the small holes which being fired gives a great
heat to the hollow box and when the plunger is brought down produces fine
impressions of the letters or devices being blocked.
