Year: 1881

page_text: LETTERS PATENT to John Marsh Day, William Robert Green, and Henry
Claude Walker, all of Falmouth Road, Great Dover Street, London, in the
County of Surrey, Engineers, for an Invention of "IMPROVEMENTS IN
MACHINERY AND APPARATUS FOR CUTTING LOAF SUGAR AND OTHER
SIMILAR SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said John Marsh Day, William
Robert Green, and Henry Claude Walker at the Office of the Commissioners
of Patents on the 9th December 1881.

IMPROVEMENTS IN MACHINERY AND APPARATUS FOR CUTTING LOAF SUGAR
AND OTHER SIMILAR SUBSTANCES."
This Invention relates to certain improvements in machinery or apparatus for
cutting loaf sugar which are applicable also to other similar sawing machines.
We propose to construct the cradle or carriage upon which the loaf is placed in
such a manner that it can readily be adjusted to suit the various shapes and sizes
of the sugar to be sawn.
For this purpose we propose to arrange the cradle which slides in horizontal
guides at an angle corresponding to that of the sides of the loaf. We further
construct the upper portion of the cradle or that part corresponding to the smaller
end of the loaf of a separate piece which can readily be removed when it is desired
to cut "titlers or "lumps "in lieu of "loaves" or vice versa and replaced by one
suited to the altered contour of the loaf to be cut.
,"
Another part of our Invention relates to apparatus whereby the cut slices are
held and supported in position This we propose to effect by furnishing each of
the gripping bars which are free to turn upon pins passing through their centre
with a number of curved fingers or claws arranged to bear upon either side of the
slices when cut and so retain the same in place.

page_text: Another part of our Invention consists in the arrangement of the locking screw
and nut whereby the gripping bars can instantly be brought to bear upon and
secure the loaf or be withdrawn from the same after it has been subjected to the
action of the saws. We propose to accomplish this by constructing the locking
gear so that the screw together with its nut can be lifted out of gear from the fixed
portion of the frame of the machine and the gripping bar be pushed forward or
withdrawn to the required extent after which by replacing the screw and nut the
necessary grip for securing the loaf can at once be given by means of a hand wheel
or lever attached to the outer end of the screw or otherwise.
These improvements can be adapted to existing machines constructed to operate
upon one or more loaves thereby increasing their efficacy and so reducing the
outlay usually incurred where separate machines are required for effecting the
above object.

We construct the cradle or carriage upon which the loaf is placed in such a

For this purpose we arrange the cradle which slides in horizontal guides at an

upper portion of the cradlo or that part corresponding to the smaller end of the
loaf of a separate piece which can readily be removed when it is desired to cut
" titlers " or "lumps" in lieu of "loaves" or vice versa and replaced by one suited

Another part of our Invention relates to apparatus whereby the cut slices aro
held and supported in position. This we effect by furnishing each of the gripping
bars which are free to turn upon pins passing through their centre with a number
of curved fingers or claws arranged to bear upon either side of the slices when cut

The accompanying Sheet of Drawing shows a machine embodying our
improvements.
Figure 1 being a front elevation of the machine.
Figure 2 is a side view and
Figure 3 a plan as shewn from above.
Figure 4 represents the cradle detached.
Figure 5 being a section through the same and
Figure 6 illustrates a plan and cross section of the upper or removable portion of
the cradle.
A A being the side frames or standards.
B is the cross bar.
C the saw frame,
D the cradle.

page_text: The loaf or titler to be sawn having been placed upon the cradle D and the
nut O raised by means of the screw N and wheel M from out of its socket the
gripping bar F is pushed forward so as to bring the fingers G to bear upon the
upper side of the loaf whereby during its passage through the saws the several cut
slices are firmly held in position. The screw N and nut O being replaced the
whole can instantly be locked together by a slight turn of the wheel M
Motion
is imparted to the cradle D in a horizontal direction by means of the handle L
and toothed wheels P Q.
These improvements can be adapted to existing machines constructed to operate
upon one or more loaves thereby increasing their efficacy and so reducing the
outlay usually incurred where separate machines are required for effecting the
above object.
Having now described and ascertained the nature of our said Invention and
in what manner the same is or may be performed,
We claim as secured to us by the hereinbefore in part recited Letters
Patent,-
Firstly. In a machine for cutting loaf sugar and other similar substances the use
of the cradle D sliding in the guides E E (when such guides are set at an angle)
substantially as and for the purpose herein before described.
Secondly. In a machine for cutting loaf sugar and other similar substances the
use of the cradle D having a movable part D* substantially as and for the purpose
specified.
Thirdly. In a machine for cutting loaf sugar and other similar substances the
use of the fingers or claws G G arranged to operate substantially as and for the
purpose herein before described.
Fourthly. In a machine for cutting loaf sugar and other similar substances the
combination of the locking screw N with the gripping bars F F¹ set movably in
the frame and operated by the wheel M substantially as and for the purpose
specified.
In witness whereof I the said William Robert Green for myself and on
behalf of my Co-Patentees, have hereunto set my hand and seal this Fifth
day of June in the year of our Lord One thousand eight hundred and
eighty two.
