Year: 1882

page_text: LETTERS PATENT to Walter Chisholm, of Hawick, in the County of
Roxburgh, North Britain, for an Invention of "IMPROVEMENTS IN APPARATUS
FOR CUTTING CHEESE."
PROVISIONAL SPECIFICATION left by the said Walter Chisholm at the
Office of the Commissioners of Patents on the 24th January 1882.

"IMPROVEMENTS IN APPARATUS FOR CUTTING CHEESE."
This Invention relates to apparatus specially designed and constructed for
cutting up large cheeses into pieces with greater rapidity and precision than as
hitherto by hand.
The Invention consists essentially in fitting a wire such as pianoforte wire in
connection with revolving or traversing wheels or gearing fixed on a framing and
cutting the cheese, by winding up the wire to draw it through the cheese or picce*
of cheese which is placed on or against the framing.
In carrying out the Invention according to one modification, the machine or
apparatus comprises a vertical fraining erected on or over a bed plate or table, and
fitted with toothed wheels gearing into each other and driven by preference by a
pinion, the spindle of which is fitted with a hand crank. On the spindle of each
toothed wheel there is fitted a grooved pulley, to which the ends of a wire are
attached in the form of a loop, so that by turning the wheels, the wire is wound
on to both pulleys simultaneously. The cheese is laid with its fut side on the bed
plate or table, and the wire passed over it. The handle is then turned to rotate
the wheels and wind up the wire on the pulleys, and by this action the wire is
drawn through the cheese and makes a clean cut through it. The cheese may then
be turned, and the same operation repeated to quarter it.
In another arrangement the wheels and pulleys are fitted
beneath the table on

page_text: which the cheese is to be cut, and a slot made in the table through which the
cutting wire may pass and be guided. The machine may be so modified that the
wire can be drawn through the cheese by fixing it to a single pulley, or a
traversing bracket, or the cheese may be traversed against a fixed wire. The
framing of the machine may be fitted with a vertically movable horizontal bracket, 5
projecting out in front over the sole plate on which the cheese rests while being
cut, and so as to be set and fixed by thumb screws or other equivalent close over
the cheeso, having a long guiding slot in it for the wire to work through, analogous
to that in the sole plate. The cheese may also be laid on its edge on the bed-
plate, so as to be sliced or cut transversely as radially, or segmentally as described. 1

"IMPROVEMENTS IN APPARATUS FOR CUTTING CHEESE."
My said Invention relates to apparatus specially designed and constructed for
cutting up large cheeses into pieces with greater rapidity and precision than as
hitherto by hand.
The Invention consists essentially in fitting a wire, such as pianoforte wire, in
connection with reversing or traversing wheels or gearing mounted on a framing,
and cutting the cheese by winding up the wire to draw it through the cheese, or
piece of cheese, which is placed on or against the framing.
And in order that the full nature and novelty of my said Invention, and the
manner of performing or putting the same into effect or practice, may be properly
understood, I will now proceed to describe the several figures on the Sheet of
Drawings which I have hereunto appended for that purpose, the samo referonco
letters indicating the same or like parts in all the figures.
Figures 1, 2, and 3 are respectively side and end elevations, and a plan, all of
one modification, or combination of the parts of a cheese cutting machine con-
structed in accordance with my said Invention and Improvements.
Referring to these Figures, the machine or apparatus comprises a vertical
framing formed of two side cheeks A secured together by stays and screw nuts A³,
carrying the whole working parts, and erected and secured at A" on or over a bed
plate B, preferably formed of hard wood for lightness and strength, and hinged
at B¹ to fold up the front part B³, on which the cheese rests, when not in use;
but the frame A, A, might otherwise be secured to a cast-iron sole-plate, or to any
ordinary table or shop counter. The frames A, A, are fitted to carry the bearing c
and spindles C of the two toothed wheels C', C³, gearing into each other, and
driven by preference by a pinion C³; the spindle C of which is fitted with a
hand crank D at one side, on the spindle C of each toothed wheel C³, C², or on
these wheels themselves, there is fitted a grooved pulley E', E2, to which the ends
of the wire E for cutting the cheese, are attached, in the form of a loop; so that by
turning the handle D and the wheels C¹, C2, C3, the wire E is wound on to both
the pulleys E' E, simultaneously. The cheese F is laid preferably first with its
flat side on the front part B2 of the bed-plate or table B, as shown dotted in
Figure 1, and the loop of the wire E passed over it. The handle D is then turned
to rotate the wheels C¹, C³, C³, and wind up the wire onto the pulleys E¹ E³; and
by this action the wire is drawn through the cheese and makes a clean cut through
it, and divides it into two halves. The cheese F so cut may then be turned and
the same operation repeated to quarter it. A further whole cheese F, or any of
the halves or quarters so cut, may also be laid on its edge on the plate B², and
thus be cut to half the depth, as on the line f, f, or sliced to other depths trans-
versely, as well as radially and segmentally as described. When desired the
wheel C and lower rim of its pulley E', may be fitted beneath the level of the
sole or table B on which the cheese rests to be cut, and have a groove or slot
formed in it as shown at through which the cutting wire E below the cheese
may pass and be guided while cutting the cheese. The wire E may also be guided
while cutting the cheese and being wound up on its pulleys E¹, E², by leading it
through the vertical slot g, in the plate C, fitted or secured on the front vertical
part of the frames at Ğ¹. And when desired, a movable horizontal plate or

page_text: bracket might be fitted by thumb screws to the upper part A² of the frames A A,
and set close over the cheese while being cut, and having a slot in it to guide the
wire passing through it, analogous to that b in the sole plate B².
Figure is a sectional elevation of a slightly different modification or arrange-
ment of my improved cheese-cutting machine from that shown in Figures 1 to 3.
In this arrangement the working gearing is mounted horizontally within the
table B, made in the form of a box for containing and protecting it. The cheese F
to be cut is laid on the table over the gearing, and is shown with the loop of the
wire E passed over it, and drawn down through a slot b, to the respective
pulleys E E, to which the ends of the wire E might be attached as in Figures 1
to 3. But I have here shown the driving handle D on the spindle C of the
pulley E³ to which one end of the wire E is attached, while the other end is passed
over the pulley El as a guide pulley, and secured in a small grooved pulley Es
fixed on the spindle of the driving pulley E², so as to have a powerful differential
action in drawing the wire E through the cheese F, as the handle D is turned and
the wire E is wound on to the large and small pulleys E Es without the use of
the two wheels C₁ C shown in dotted lines in the figure; although one or both
of these wheels may be used with or without a third spindle C and pinion C³,
when desired, actuated by the handle D.
The machine may be so modified that the wire E can be drawn through the
cheese by fixing it to a single pulley E' or E, and having the other end of the
wire secured to a fixed point in the frame A, B; or by a traversing or toothed
rack drawing the moving end of the wire. By another arrangement the two ends
of the loop wire E might be fixed, and the cheese be traversed against it on a
movable table worked by racks and pinions.
----Having thus described my said Invention, and the manner of performing the
same, I have to state that I do not restrict. myself to the precise details herein
described or delineated, but what I believe to be novel and original-and-therefore
claim as the Invention secured to me by the herein before in part recited Letters
Patent is,--
First. The construction or combination of the parts of a machine or mechanism
for the cutting of cheese, substantially as herein described in reference to and
shown in the accompanying Drawings.
Second. The construction of a cheese-cutting machine having a loop wire E
drawn through the cheese to cut it, by winding the wire on two pulleys, or it
might be on one pulley, substantially as herein described, in reference to and showu
in the accompanying Drawings.
In witness whereof, I, the said Walter Chisholm, have hereunto set my
hand and seal this Twelfth day of July, in the year of our Lord, One
thousand eight hundred and eighty two.
