PROVISIONAL SPECIFICATION.
A Method of Producing Flat Pictorial Models in Separable Component
Pieces or Parts.
I, CHARLES WILLIAM DIMMOCK BOXALL, of 51 Cavendish Street in the City
of Sheffield, Organiser of Manual Training, do hereby declare the nature of my
invention to be as follows:-
This invention relates to a method or system of representing the whole or part
of an object, building, machine, or a portion of same, or any system of construction,
in such a manner as to bring into view any part, detail, or section, so as to show
the method of building up the various component parts thereof, such for example as
the several parts of the timber in roofing a building, and either by the aid of
geometrical, isometrical, true or other kind of perspective, projection, or method of
representing such things on flat material, showing oue, two or more sides and also
giving views on both sides of the material whore required, a system very useful for
educational purposes.
I cut such drawn objects out of flat material (such for example as card-board)
made preferably in two or more thicknesses, to permit slits being made through it,
for other parts to be passed through, where it is desirable to represent one part as
penetrating or passing through another, or where pieces of material are shown as
fixed upon or under others.
Such parts although flat can apparently be jointed, dovetailed, mortised, or
otherwise put together and taken apart as if they were made in the solid, in such a
manner as to clearly illustrate, and impart such instruction how such parts are
constructed and fitted together in practice, and the relation which they bear to
each other.
The drawings may be executed in line only or in line shaded, coloured or
otherwise.
A Method of Producing Flat Piotorial Models in Separable Component
Pieces or Parts.
I, CHARLES WILLIAM DIMMOCK BOXALL of 51 Cavendish Street in the City
of Sheffield Organiser of Manual Training, do hereby declare the nature of this
invention and in what manner the same has to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to a method or system of representing the whole or part
of an object, building, machine, or a portion of same; or any system of construction,
in such a manner as to bring into view any part, section or detail, so as to exhibit
the method of building up the various component parts thereof, such for example
as the several timbers used in the construction of a roof, and their joints. This

page_text: may be done by the aid of geometrical, isometrical, true or other kind of perspective,
projection, or method of representing such things on flat material, showing one, two,
or more sides, and also giving views on both sides of the material where required,
constituting a system of instruction very useful for educational purposes.
I have illustrated my invention in the annexed sheets of drawings, both the
objects shown being of a simple character.
Fig. 1, is a perspective view of a pedestal fitted with a top and bottom brass,
showing the front and the upper sides.
Fig. 2, view of same showing half longitudinal and half cross section.
Fig. 3, represents a flat removable piece of same.
Fig. 4, reverse view of removable piece.
Fig. 5, reverse of Fig. 1, showing the back and underside.
In carrying out my invention in producing for example the representation of a
pedestal and brasses, I first draw the object upon a piece of flat material to the
outline of Fig. 2 and cut it out, indicating all the several parts and the sections by
lines or colours as preferred, as shown for example in Fig. 2, I then draw the
part as in Fig. 3, and cut it out, painting or lining the back to represent the section
corresponding with that of Fig. 2, and when this is placed against Fig. 2, as shown
in Fig. 1, (the position being indicated by the dotted lines) the representation is
complete.
The reverse sides of the two parts may be lined and coloured to represent the
back and the undersides of the pedestal as shown in Fig. 5, thus it will be seen that
five different views of the pedestal or parts of same are produced by the use of two
pieces of flat. material having the appearance of a solid model, and if drawn in
isometrical perspective the parts may be measured by an ordinary rule.
In' the representation of an ordinary mortice and tenon joint, such as are so
commonly used in timber work, and which is illustrated in Figs. 6. 7. 8. 9 in
perspective, Figs. 6 and 7 showing the two parts put together, and Figs. 8 and 9
the two parts separated, I proceed as follows:-
I draw and then cut out a piece of flat material to the shape of Fig. 10, the
reverse of which is shown in Fig. 11, I also draw and cut out Fig. 12, the reverse
appearing as Fig. 13, and I paste, glue, or otherwise stick or attach the reverse
sides of the two pieces together on the parts or surfaces where they are covered
with section lines, the-plain or unlined part or parts being left unattached.
In this case the part A, indicated by the dotted lines in Figs. 8, and 12, will
form'a flap in front of the part B, for the purpose of passing in front of the part C',
indicated in Figs. 8, and 14, by dotted lines, and represented in Fig. 6.
For the morticed portion of the joint C, I cut out the pieces 14 and 16, their
reverse sides being shown in Figs. 15, and 17, and pierce through them an L shaped
elot or slit indicated in all the said figures by a thick line C, and I paste or
otherwise attach the backs of these pieces upon the surfaces which are lined but
not upon the plain parts marked C.
This arrangement leaves a clear slit or passage through which the fiat part B,
representing the tenon can be passed to its position as shown in Fig. 6; the extreme
end B', which projects from the slit as seen in Fig. 7, is drawn to represent the end
grain of the wood.
2
The various figuring or graining of the wood may be drawn or painted upon parts
or upon the whole of tho flat parts of the model.
Wherever desirable, such as between the two parts Figs. 14 & 16, an intermediate
thickness of material may be placed at each side of the slit C, for the purpose of
enabling the tenon B, to enter and to pass more freely through the slit.
The material used may be cardboard or other analogous material, thin sheet metal,
or any sheet material that will answer the purpose of the invention, or a combination
of such materials.
It will be understood that the objects which I have illustrated are merely chosen
for the purpose of explaining the manner in which my invention is or may be
carried out, as it will lend itself to the representation of much more complicated

page_text: designs and objects having many more parts, I also wish it to be clearly understood
that I do not claim the use of a design made in one piece, but
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1. The production of flat pictorial models in two or more separable component
parts by the method of construction herein before described, and shown in the
drawings.
2. The method of illustrating the construction of machinery, buildings and other
objects, or parts of such objects, by the aid of flat models capable of being
subdivided, as herein before described and shown.
