Improvements in Apparatus for Cutting and Trimming Card, Paper,
Cloth, and other Materials or Substances.
I, JOHN MERRETT, of Trowbridge, in the County of Wilts, Accountant do hereby
declare the nature of this invention to be as follows:-
This invention relates to apparatus for cutting and trimming card, paper,
cloth and other materials or substances.
The apparatus comprises two shearing or cutting blades mounted on boards
or plates which are hinged to a baseboard or bed plate in planes at right angles
to each other, the boards or plates being pressed into contact with each other by
suitable springs. The boards or plates carrying the cutting blades are so dis-
posed that one of the blades is held in a stationary position while the other
moves over it in a parallel plane so as to make a constant angle with the stationary
blade. The board or plate carrying the moveable blade is operated by hand,
foot or machine power and instead of being hinged it may be pivotted or mounted
on trunnions so as to have a rocking motion.
The card, paper, cloth, or other material or substance to be cut or trimmed is
preferably inserted in a recess made for the purpose between the moveable blade
and the board or plate to which the latter is secured.

Improvements in Apparatus for Cutting and Trimming Card, Paper,
Cloth, and other Materials or Substances,
I, JOHN MERRETT, of Trowbridge, in the County of Wilts, Accountant, 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:-
This invention relates to apparatus for cutting and trimming card, paper,
cloth and other materials or substances.
The accompanying drawings, which are furnished by way of illustration only,
show two forms in which the apparatus may be constructed.
Figure 1 is a perspective view showing one form of my invention in action,
Figure 2 is a sectional side elevation of same, and Figure 3 is a rear elevation
of one of the cutters; Figure 4 is a perspective view showing another form of

the invention in action, and Figure 5 is a sectional side elevation of same.
same letters of reference where they occur are used to denote the same or corre-
sponding parts in all the figures, and for convenience of reference and identi-
fication the various parts are marked and lettered as follows;-
A Base frame or base board.
B Cutting board.
CC Hinges of board.
D. Rule gauge on board.
E Cutting blade on board.
F Spring for rising. board.
G Rear cutting blade.
L Hinges to cutting blade-refers to Figs. 1, 2 and 3 only.
HH Spring to cutting blade.
II Stops on cutting blade.
J Bracket. Refers to Figs. 4 and 5 only.
K Bar. Refers to Figs. 4 and 5 only.
In the form shown in all the Figures, A is the base (being a board or frame
of wood, or other material.) B is the cutting board, or the board on
which the photographic print or material is placed for cutting. CC are the
hinges by which the cutting board is attached to the base. 1) is a rule gauge
fixed to the cutting board and which regulates the size to which the print or
material is to be cut or trimmed and also acts in conjunction with the cutting
blade. E as a square and ensures that the print or material is squarely cut or
trimmed. E is the cutting blade affixed to the cutting board B with a space
between it and the board of sufficient width and depth to allow the print, or
material to be trimmed or cut, to be pushed through between the cutting board B
and the cutting blade E. Fis a spring placed between the base .A and the
cutting board B and either attached or loose and pressing on the underside of
the cutting board B in such a way as to keep same raised to its normal position.
G is a blade of tapering form. as shown in Fig. 3 and is made of one or more
pieces of metal and having a cutting edge on the top side and which is hinged to
the base A by hinges L and L.
His a spring (or springs) fixed to the base, and when in action pressing the
blade G against the front edge of the cutter blade E.
I and I are stops fixed on the inner and outer sides of the cutting blade G
respectively. The stop I prevents the cutting board B from being pressed down
further than is necessary for the purpose of making the cut, and the stop I'
prevents the cutting board B from being raised by the spring F beyond the
cutting edge of the blade G.
For convenience of packing the spring H H fold downward to the base and
the cutting board B also folds down to the base and is held in position by a turn
button.
In using the apparatus the print or material to be trimmed or cut is placed
on the cutting board B with such part as is intended to be cut or trimmed off pro-
jecting outward under and beyond the cutting blade E.
The cutting board B is then pressed down as far as it will go; the print or
material is thereby carried against the edge of the knife and by the action of
the cutting blades, which are thus brought into contact and act as shears, the
cut is made, the cutting angle of the blades being exactly the same at every
point of contact throughout the stroke, the cutting blades only coming, into
contact at the actual cutting point for the time being.
In the form shown in Figs. 4 and 5 the cutting action is reversed the cutting
board is hinged to the base across the centre (or near thereto) of the base in, a
line with the knife. A spring is normally under the cutting board in such a
way as to keep that end of the board which is furthest from the cutting blade
raised to the normal position the other end of the cutting board being corre-
spondingly depressed. The cutting blade E is fastened to the surface of the

page_text: upper end of the cutting board B and let into and flush with such surface. The
blade G is pivotted on a bar K supported by brackets J fixed to the base.
In using this form of the apparatus the material to be cut or trimmed is
placed on the cutting board B with the part thereof to be cut or trimmed off
projecting over and beyond the cutting blade E and under the blade G that
end of the cutting board which is farthest from the cutting blades is then
depressed and the end nearest the blades is correspondingly raised, the print
or material is thereby carried upwards to the blade C and the cutting blades E
and G being thereby brought into contact is made. The cutting angle at the
point of contact between the blades being exactly the same throughout the stroke.
The advantage of this second form of cutter is that the print or material
to be cut or trimmed is not marked by any part thereof being placed under
the cutting blade E.
It will be obvious that the board B and cutting blade G may be pivotted
instead of being hinged to the base board, or they may be mounted on trunnions
or otherwise arranged so as to have the combined cutting or shearing action
hereinbefore described. It will also be obvious that the moving cutter E may
have a blunt or practically a blunt edge instead of a cutting edge all the cut
being effected by the inclined knife.
Having now particularly described and ascertained the nature of this inven-
tion, I declare that what I claim is:--
1. Apparatus for cutting and trimming card, paper, cloth or other materials
or substances, consisting of two cutters mounted on a base board with their
operative edges at right angles to each other, one cutter having an oblique
cutting edge and a spring to hold it in contact with the other cuter, the second
cutter having a straight cutting or blank edge and being mounted on a spring
so as to be moveable over the face of the first cutter at a constant angle, and
provided with an aperture or space to receive and hold between the operative
edges the edge of the material to be severed, substantially as and for the purpose
hereinbefore described with reference to the accompanying drawings.
2. Apparatus for cutting and trimming card, paper, cloth or other materials
or substances, consisting of two cutters mounted on a base board with their
operative edges at right angles to each other, one cutter having an oblique cutting
edge and a spring to hold it in contact with the other cutter, the second cutter
having a straight cutting or blank edge and being mounted on a spring so as
to be moveable over the face of the first cutter at a constant angle, substantially
as and for the purpose herein before described with reference to the accompany-
ing drawings.
3. Apparatus for cutting card, paper, cloth or other materials or substances,
consisting of a base, two cutters mounted thereon with their operative edges at
right angles to each other, one cutter having an oblique cutting edge, a spring
to hold said cutter against the other, a spring to hold the second cutter at the
starting position, all combined to operate substantially in the manner and for
the purpose hereinbefore set forth with reference to the accompanying drawings.
4. Apparatus for cutting card, paper, cloth or other substances, in which two
cutters are mounted with their operative edges at right angles to each other and
constructed and combined to operate substantially as and for the purpose herein-
before described with reference to the accompanying drawings.
