Improvements in or relating to Map or Chart Stands.
I, WALTER LYON SINTON, of 15 Broad Street, in the City of Victoria, in the
Province of British Columbia, Dominion of Canada, Gentleman, do hereby declare
the nature of this invention to be as follows:-
The object of the invention is to provide a map or chart stand which may be
readily taken apart and put into a portable condition, and by means of which the
map or chart may be unrolled and hoisted from a spring roller located near the
base of the stand so as to render the stand peculiarly stable by keeping the weight
as low as possible when the map is rolled or only partially unrolled; and which
displays in the first instance the upper portion of the map or chart instead of the
lower portion, as is usually the case.
The device consists essentially of a hinged folding standard provided with jaws
at its lower end, adapted to engage with and be secured to separable base pieces, a
transverse holder located on and removably secured to the lower part of the hinged
standard, a spring roller suitably journalled on said holder for carrying the map or
chart, a pulley attached to the top of the standard, and means for hoisting the map
or chart from the spring roiler towards the top of the standard, as hereinafter more
particularly described.
One of the base pieces has a notch formed in the bottom and the other a notch
formed in the top.
When these pieces are placed together the sides of the notches
engage with the lower and upper portions of the two base pieces respectively,
a hook being provided to connect the base pieces with the bottom of the standard
so as to enable the latter to be moved without becoming detached from the base
pieces.
The standard is preferably scarf jointed at its hinged part. The upper and lower
portions of this standard are provided respectively with a pivoted hook and eye or
vice versa, in order to keep the scarf joint closed and the hinged standard in an
upright position when unfolded and in use. Although this is the preferable way
of connecting the upper part of the standard with the lower portion thereof, instead
of being hinged these portions may be detachable and the scarf joint may be held
together by a sleeve slid over it, or the parts may be connected by means of a
mortise and tenon or in any other way which renders them readily detachable or
capable of being folded when the stand is not set up.
The transverse holder is fitted into a notch formed on the lower part of the
standard and held in place by means of a thumb screw which enters into a threaded
hole or nut fitted at the back of the transverse holder. Although this is the
preferable way of connection with the standard, it may be otherwise connected
so as to be readily detachable when the stand is taken apart for convenience of
portability.
The spring roller on which the chart or map is rolled is of ordinary construction
and is journalled in bearings attached to the transverse holder.
A slat to which the top of the chart is attached, is provided with a ring to which
is connected, by a hook or equivalent, a string or halyard. This halyard passes
over the before mentioned pulley at the top of the standard when it is set up for
use, so that by pulling on the free end of the halyard the map or chart is unrolled
from the spring roller and the upper part thereof is first displayed. The free end
of the halyard may be secured to a cleat on the lower part of the standard in the
usual manner.

page_text: The location of the roller on the holder near the base of the standard keeps the
weight lower down when the map or chart is rolled or only partially unrolled, and
thus renders the stand much more stable than the ordinary kind of stand in which
the holder is placed near the top of the standard and the map or chart is drawn
downwards from above in order to display it. The folding standard is detachably
connected with the separable base pieces by means of jaws which are formed on the
end of the standard.
By the foregoing construction it will be seen that I have provided a stand which
is readily detachable and capable of being packed into a small space when it is
necessary to move the same to any distance.

Improvements in or relating to Map or Chart Stands.
1, WALTER LYON SINTON of 15 Broad Street in the City of Victoria, Province
of British Columbia, Dominion of Canada, Gentleman, do hereby declare the
nature of this invention and in what manner the same is to performed, to be
particularly described and ascertained in and by the following statement :-
The object of the invention is to provide a map or chart stand which may be
readily taken apart and put into a portable condition, and by means of which the
map or chart may be unrolled and hoisted from a spring roller located near the
base of the stand so as to render the stand peculiarly stable by keeping the weight
as low as possible when the map is rolled or only partially unrolled; and which
displays in the first instance the upper portion of the map or chart instead of the
lower portion, as is usually the case.
The device consists, essentially, of a hinged folding standard provided with jaws
at its lower end, adapted to engage with and be secured to separable base pieces, a
transverse holder located on and removably secured to the lower part of the hinged
standard, a spring roller suitably journalled on said holder for carrying the map or
chart, a pulley attached to the top of the standard, and means for hoisting the map
or chart from the spring roller towards the top of the standard, as hereinafter more
particularly described.
In the accompanying drawings:
Figure 1 is a perspective view of the chart stand with the chart rolled up.
Figure 2 is a perspective view of the standard detached and folded.
Figure 3 is a perspective view showing the back of the spring-roller holder,
detached from the standard and
Figure 4 is a perspective view of the separable base pieces.
Like letters of reference indicate similar parts in the various figures.
In Figures 1 and 4 A A' are separable base pieces, one of which viz. A¹ has a
notch M formed in the bottom, and the other (A) a notch L formed in the top.
When these pieces are placed together, the sides of the notch M engage with the
lower portion of the base pieces A and the sides of the notch L with the upper part
of the base piece A¹. They are shown fitted together in Figure 1.
a is a look
which connects the base piece with the bottom of the standard so as to enable the
latter to be moved without becoming detached from the base pieces.
B is the standard preferably scarf jointed at 6 and hinged at b'. The upper and
lower portions of this standard B are provided respectively with a pivotted hook I
and eye J as shown in Figure 2, or with the reverse of this arrangement, in order
to keep the scarf joint closed and the hinged standard B in an upright position
when unfolded and in use. Although this is the preferable way of connecting the

page_text: upper part of the standard with the lower portion thereof, instead of being hinged,
these portions may be detachable and the scarf joint may be held together by a
sleeve slid over it, or the parts may be connected by means of a mortise and tenon,
or in any other way which renders them readily detachable or capable of being
folded when the stand is not set up.
C is a transverse holder fitted into a notch e¹ formed on the lower part of the
standard B (see Figure 2) and held in place by means of a thumb screw d which
enters into a threaded hole or nut d¹ fitted at the back of the transverse holder C
as shown in Figure 3. Although this is the preferable way of connection with the
standard, it may be otherwise connected so as to be readily detachable when the
stand is taken apart for convenience of portability.
D (see Figure 1) is the chart or map which is rolled on the spring roller E.
The spring roller on which the chart or map is rolled is of ordinary construction
and is journalled in bearings e attached to the transverse holder C.
S is a slat to which the top of the chart is attached and which is provided with a
ring to which is connected, by a hook or equivalent g one end of a string or
halyard G. This halyard G passes over the before mentioned pulley H which may
be of any suitable construction, fixed at the top of the standard when it is set up for
use, so that by pulling on the free end of the halyard G, the map or chart is
unrolled from the spring roller E and the upper part thereof is first displayed.
The free end of the halyard G may be secured to a cleat on the lower part of the
standard B, in the usual manner.
The location of the roller on the holder near the base of the standard keeps the
weight low down when the map or chart is rolled or only partially unrolled, and
thus renders the stand much more stable than the ordinary kind of stand in which
the holder is placed near the top of the standard and the map or chart is drawn
downwards from above in order to display it. The folding standard B, is detach-
ably connected with the separable base pieces A A' by means of jaws K K' which
are formed on the end of the standard (see Fig. 2). In Fig. 1, those jaws are
shown in place engaged with the base pieces, and the hook a on the base piece A is
hooked into an eyelet formed on the lower part of the standard.
By the foregoing construction it will be seen that I have provided a stand which
is readily detachable and capable of being packed into a small space when it is
necessary to move the same to any distance.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is;-
