PROVISIONAL SPECIFICATION.
Improvements in Apparatus Employed in the Manufacture of Fuel
Blocks.
I, WILLIAM BAKER HARTRIDGE, of No. 28, Victoria Street, Westminster, in
the County of London, Engineer, do hereby declare the nature of this invention
to be as follows:-
In my Specification No. 26,873 of 1896, I have described apparatus for manu-
facturing fuel blocks in the form of tubular pieces with holes through their
sides. My present invention relates to apparatus for cutting these pieces from
a length of tube and punching the holes through their sides.
I mount this apparatus in front of the machine from which the continuous
tubes of the fuel material are extruded, so that lengths of these tubes can be
readily pushed forwards to the base of the apparatus where they are received
in grooves of semi cylindrical form, when the tubes are of circular section or of
other form corresponding to the section of the tube.
Above this base there is a vertically sliding pressing block similarly grooved
on its underside and a separate sliding block carrying punchers and cutters..
The latter or punching block is linked to an overhead crank or eccentric causing
it to reciprocate vertically.
It meets stops on the pressing block so that at the latter part of its upstroke
it raises this block, at which moment. the tubes are pushed under it;
then as
the punching block begins to descend, the pressing block first descends so as to
clamp the tubes between it and the base, and as the punching block continues
to descend the knives cut the tube to lengths enclosing the ends of each length
and then the punches pass through the sides of the tubes.
On the blocks again ascending a fresh length of tube is advanced extruding
the punched and cut lengths, which are removed.

page_text: and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
In my Specification No. 26,873 of 1896 I have described apparatus for manu-
facturing fuel blocks in the form of tubular pieces with holes through their
sides.
My present invention relates to apparatus for cutting these pieces from a length
of tube and punching the holes through their sides, as I shall describe referring
to the accompanying drawings. Fig. 1 is a vertical section and Fig. 2 is
a side view of apparatus according to my invention.
I mount this apparatus in front of the machine of ordinary construction from
which the continuous tubes of the fuel material are extruded, so that lengths of
these tubes can be readily pushed forwards to the base of the apparatus where
they are received in grooves a of semi cylindrical form, when the tubes are of
circular section, or of other form corresponding to the section of the tube.
Above this base there is a vertically sliding heavy pressing block b similarly
grooved on its underside, and above it a separate sliding block e carrying
punches and knives e. The block c is linked by a connecting rod f to an
overhead crank or eccentric causing it to reciprocate vertically.
It meets stops g on the arms which carry the pressing block b so that at the
latter part of its upstroke it raises this block at which moment the tubes which
have had their ends cut by the knives c and have been perforated by the
punches are pushed from under it.
As fresh lengths of tube are advanced into the grooves a, then, as the punch-
ing block begins to descend, the pressing block first descends so as to clamp
the fresh tubes between it and the base, and as the punching block continues
to descend the knives cut the tubes to lengths enclosing the ends of each length
and then the punches pass through the sides of the tubes perforating them as
shewn at c and d¹.
On the blocks again ascending fresh lengths of tube are advanced extruding
the punched and cut lengths, which are removed.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:
Apparatus for cutting and punching tubular pieces of artificial fuel constructed
and operating substantially as described with reference to the drawings.
