PROVEMENTS IN MACHINERY FOR CUTTING SUGAR."
"IM-
This Invention has for its object improvements in machinery for cutting sugar.
The machine consists of a table on which the sugar to be cut is laid. The
sugar then as it is brought to the machine is in the form of bars, say one inch square
aud several inches long. The bars, say to the number of two dozen, more or
less, are laid side by side on the table, and are pushed forward step by step beneath
a fixed blade, and after every forward motion a moving blade rises, and portions of
suitable size are thus nipped off the ends of the bars. At the moment when the
nip takes place the bars are held in position by a presser which comes down upon
them immediately behind the upper blade. The pieces nipped from the bars fall
upon a riddle. The riddle has a jogging movement given to it, and it leads the
pieces of sugar into a suitable receptacle whilst the smaller fragments pass through
the riddle and are received separately.
The machine is actuated by a shaft on which are cams for giving a rising and
falling motion to the lower nipping blade. This blade is carried by arms which
rest upon the cam, and at their further ends aro jointed to brackets fixed beneath
the table. The main axis also carries an eccentric to actuate the presser. The
eccentric rod is jointed to an arm on a rocking shaft on which are other arms
connected with rods attached to the presser. The inain axis also by means of an
eccentric pin gives motion to a long pawl taking into ratchet teeth which extend
partly around the periphery of a wheel having on its axis pinions engaging with
racks in connection with a saddle extending across the table, and this saddle carries
the pusher which pushes the bars of sugar forward step by step to the nipping
blades. The pusher is fixed on arms jointed to the saddle, and they travel forward
together until the driving pawl has taken the last tooth of the ratchet wheel. The
pusher will then have advanced close up to the nipping blades, and in the mean-
tine the attendant has placed a fresh lot of bars of sugar behind the pusher. He
then throws out the pawl, and draws back the saddle by hand. The pusher is pro-
vided with guides, which cause it during the return movement of the saddle to risc
above the bars of sugar which have been placed behind it. The pusher remains
raised until it has passed the bars. It then falls down again ready to propel

movement recommences.
To cause the pusher to lift during the return of the saddle there are pins upon
it on either side, which as the pusher moves forward pass beneath latches which
at their hinder ends are carried upon pins on which they are able to turn. During
the last part of the forward movement of the pusher the pins come against inclines
on the latches and lift them, and afterwards the pins pass beyond the ends of the
latches which then again fall, so that when the saddle is drawn back the pins ride
upon the backs of the latches, and these are so formed as to raise the pushers to
the extent required. When the saddle has been drawn back sufficiently far to
bring the pusher past the bars of sugar on the table the pins on the pusher again
escape from the latches, and the pusher falls to its working position.
