Improvements in Chopping and Grating Machines.
We ELIJAH HERMAN ALLSOPP 41 Church Gate Loughborough, Leicestershire,
Draper and JOHN CHAPMAN ALLSOPP 44 Kirkby Street Nottingham, Mechanic
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a plan of one of our improved chopping and grating machines.
Figure 2 a right side view of the same.
Figure 3 a right side view of three cams, and
Figure 4 an end view of a loose plate, each severally hereafter referred to.
Each machine consists of the following parts, a metal frame A secured to a wood
or metal block A¹ the frame A forms bearings for a pair of horizontal axle shafts 1
and 2. From the right side of the frame a short axle 3 projects, and within the
frame is a vertical axle 4.
On the axle shaft 1, three double armed levers B, B', B', rock, each lever has a
vertical cutter blade B secured to it by three screws, the lower edge of each blade
is alternately pressed on to a circular block C by one of three springs B4 bearing on
the lower side of the back end of the double armed lever, the lower end of each
spring is secured to a flange B' which extends across the frame A.
"
Each of the three levers and cutter blades are alternately lifted to the height
shown by B' at Figure 2 by means of one of three cams B' "shown at Figure 3
which are carried by a shaft 2 provided at its right end with a toothed spur
wheel B' gearing into a toothed wheel B carried by the axle 3.
The outer side of the wheel B" is provided with a handle B' by which the
machine is worked, on the inner side of the wheel a flange projects provided with
an india rubber band B which presses up to the under side of the circular block C
causing it to be revolved by friction. The stem beneath the block being bored out
to receive the vertical axle 4 round which it revolves.
The block C carries a circular box of metal C¹ which forms a receptacle for the
substance to be chopped, the box is covered by a loose lid provided with a vertical
flange Cround half its circumference to prevent the chopped substance from being
scattered.
The lid has three parallel slots C³ cut in it, through which the cutter blades B
rise and fall, two blades remain in their slots while the third blade is being lifted,
thereby preventing the lid from revolving with the cutter block.
A fourth slot is cut in the left side of the lid at an angle to the parallel slots, in
the inclined slot a loose plate C₁ "shown at Figure 4 is dropped, when the
machine is used to chop mint, thyme, or other substance small.
The left end of the shaft 2 carries a three armed fly wheel D provided on its
outer face with a grater plate D¹ enclosed by a cover D' provided at its centre with
a narrow shelf D³ reaching from the left of the cover to within a short distance of
the face of the grater, upon this shelf the substance to be grated is held by the
attendant and pressed to the grater.
The back end of the cover D' terminates at the bottom in a pin D' which takes
into a hole in the block A', the front end of the cover carries a hooked rod D* which
hooks on to the left side of the metal frame A, the pin and hook keep the cover
in position while the grater is being used, the grated substance falls into a drawer E
which slides into a recess formed in the left side of the block A'
When the grater plate gets clogged or requires cleaning, upon the cover D' being

page_text: removed, by loosening the thumb screw D' the wheel D and grater plate may be
removed and cleaned by brushing or washing it.
When the substance in the box C¹ has been sufficiently chopped, upon the
machine being stopped the attendant may throw back each of the levers carrying
a cutter blade into the position shown by the dotted lines at Figure 2 to enable him
to take off the cover of the box and lift the box C¹ and block C clear of the machine
to empty out the chopped substance.
The above described machine is applicable for chopping or grating suet, cooked
meat, apples and other fruit, potatoes, horse radish and other vegetables and for
grating spices.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what we
claim is :-
The construction and employment of chopping and grating machines substantially
as described and illustrated in the drawings annexed.
