Improvements in or relating to Binding and Exhibiting Maps,
Charts, Diagrams, and the like.
I, SPEDDING CURWEN, of North Street, Plaistow, in the County of Essex,
Publisher, do hereby declare the nature of this invention to be as follows:-
This invention relates to binding and exhibiting maps, charts, educational and
other diagrams and the like, its object being the construction of convenient means
for storing several series of such diagrams safely and in order and enabling the
individual diagrams of any series to be displayed in succession or one series to be
exchanged for another with any desired degree of rapidity, and without risk of
being torn or otherwise accidentally injured.
According to this invention the diagrams constituting a series are strengthened
near their edges and there perforated; rings are placed in the perforations to bind
the series together and are engaged with a rod or lath, which may if desired be
extensible. A stand or easel which also may be extensible is provided at its upper
part with jaws to receive the ends of the rod or lath, so as to hold the series in a
convenient position for display; at or about the centre of the stand or easel and
preferably at the rear are arms or projections to support similar rods or laths
carrying in a position readily accessible, other series of diagrams intended for use
with the apparatus. Conveniently the series in course of display is so placed us to
overhang the several other series; for example one series during display hangs
down in front of the stand or easel from the top, the individual diagrams being
successively turned up and over the top, moving upon the rings, the several other
series hanging down behind the apparatus from their rods or laths supported on the
aforesaid arnis or projections.
The jaws and arms or projections may be smooth or serrated or notched; they
may be formed in the material of which the stand or easel is made, or may be of
iron or other metal fixed to or adjustable upon it. For example, pieces of sheet
metal can be slotted and so bent as to form light but rigid jaws or arms in which
the slots form recesses suited to receive the rods or laths and retain them in the
desired position.
It will be understood that modifications may be made without departing from
the spirit of the invention, for instance the easel or stand may be dispensed with,
and the lath carrying the maps, charts etc. may be suspended from the ceiling, roof,
beam or the like by convenient means.

Improvements in or relating to Binding and Exhibiting Maps,
Charts, Diagrams, and the like.
I, SPEDDING CURWEN of North Street, Plaistow, in the County of Essex,
Publisher, 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 binding and exhibiting maps, charts, educational and
other diagrams and the like, its object being the construction of convenient means
for storing several series of such diagrams safely and in order and enabling the
individual diagrams of any series to be displayed in succession or one series to be
exchanged for another with any desired degree of rapidity, and without risk of
being torn or otherwise accidentally injured.
According to this invention the diagrams constituting a series are strengthened
along their top edges and small rings are attached thereto or perforations made
therein; large rings are threaded through the smaller rings or perforations to bind
the series together and are engaged with a rod or lath upon which they hang.
A stand or easel which may if desired be extensible is provided at its upper part
with racks or jaws to receive the ends of the rod or lath so as to hold any series in
a convenient position for display; at lower parts of the stand or easel are projections
in the form of racks to support similar rods or laths, carrying in a position readily
accessible, other series of diagrams intended for use with the apparatus. Con-
veniently the series in course of display is so placed as to overhang the several
other series; for example one series during display hangs down in front of the
stand or easel from the top, the individual diagrams being successively turned up
and over the top, moving upon the rings, the several other series hanging down
behind the one being displayed.
The racks or projections may be smooth, or serrated or notched; they may be
formed in the material of which the stand or easel is made, or may be of iron, or
other metal fixed to or adjustable upon it.
In the accompanying drawings:-
Figure 1 shows one form of chart stand according to this invention with a series
of charts suspended therefrom.
Figure 2 is a detail of Figure 1 to a larger scale and
Figure 3 shows one method of attachment of a series of charts to a lath for the
purposes of this invention.
Like letters indicate like parts throughout the drawings.
With reference first to Figures 1 and 2, two uprights A forming the sides of the
stand are supported on feet A, B are extensible ends to form continuations of
the uprights A; they are slotted, as shown, at B¹ and clamped to the uprights A
with thumb screws B which pass through the slots and enable the charts which are
to be carried at their upper ends, to be held at different heights. Cross pieces C C¹
join the uprights A to give them rigidity and to keep them the right distance apart.
Any convenient number of these cross pieces may be used.
At the top of the frame are two racks D projecting inwardly with a slot D' or
slots in each to receive the ends of the lath carrying in the manner hereinafter
described the charts which are being exhibited. Similar racks D with any desired
number of slots are placed lower down on the stand in convenient positions for
storing charts which are not being used at the moment.
In Figure 3 are shown charts or diagrams E, each with a strengthened top
edge E. To this are attached at suitable distances apart, small rings E. F is a
lath with holes F drilled therein at distances apart to correspond with those

page_text: between the rings E' in the chart; in these holes are rings F which extend round
the top edge of the lath in the manner illustrated. The small rings E2 of the
charts are then threaded on to the larger rings F, of the lath, thus attaching
the charts to the lath F in such a manner that they can be turned over freely one
by one to the back of the lath, exposing to view any particular one required.
When in use the ends of the lath are placed in the slots D' (Figures 1 and 2) of
the upper racks D; when not in use, the laths can be supported in the slots of the
other and lower pairs of racks D, these racks being disposed at suitable distances
apart to correspond with the length of the lath. Instead of the rings F passing
through holes in the lath, they may encircle a rod preferably of circular section,
the ends of the rod engaging in the slotted racks. The ends of the rods or laths.
should preferably be reduced or "shouldered" as at F3 Figure 3, the shoulders
serving to prevent any endwise movement of the rods or laths, by engaging as in
Figure 2 with the opposed face of the rack or the like.
Instead of having rings E2 attached to the chart in the manner indicated in
Figure 3, holes may be punched in the chart and lined with metal eyelets, through
which the rings F of the lath or rod can be passed directly.
It will be understood that modificatious may be made without departing from the
spirit of the invention for example, instead of a stand constructed in the manner
indicated in Figure 1, a folding easel may be employed in which two rear legs for
instance are pivotted to a pair of front legs somewhat in the manner of a step
ladder. In this construction brackets racks or notches may be applied to the front
legs or to both the front and rear legs for the support of laths carrying charts or
diagrams in the manner already indicated.
It is preferred that when this form of easel is in use the front and rear legs should
slant away from each other and out of the vertical, in which case a series of
diagrams supported at different heights from either pair of legs will depend
vertically from their laths so as to overlap and hang one behind the other. Con-
veniently this folding easel may be built up of wooden rods connected by dowels
or keys so that the whole structure can be readily taken to pieces if desired and
packed into a small compass. Or the easel or stand may be dispensed with, and the
lath carrying the maps, charts, etc., may be suspended from the ceiling, roof, beam
or the like by any convenient means.
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. A stand or easel adapted to support in the manner described different series
of charts diagrams or the like.
2. A folding easel with slanting legs adapted to support in the manner described
different series of charts diagrams or the like.
3. The combination with a series of maps, charts or the like suspended from
rings F of a rod or lath supporting such rings substantially as and for the purpose
described.
4. The "binding" for maps charts and the like substantially as described and
illustrated in Figure 3 of the accompanying drawings.
5. The combination and arrangement of parts constituting the complete apparatus
for storage and exhibition of maps charts and the like substantially as described
and illustrated in Figures 1 and 2 of the accompanying drawings.
