Varnished wood frame, with plastic card scales showing LAT and
LAT + 1hour in 10 min. intervals. Hand written scale, dia 10in., instrument height 18in. Nodus position is adjustable
to allow its shadow to be placed on the scale centre line. A secondary plane scale gives, Date, Dec. of Sun and
EQT readings. There is no equatorial base included, but the instrument obviously requires one and is designed to
be rotated on a polar pin to allow Longitude and EQT to be applied to give clock time. A third scale +/-60 min.
is provided on the rim to allow the whole instrument to be rotated to set the adjustment. The base carries some
instructions . |

Large Universal Equatorial Dial |
| |
This Universal Equatorial has been constructed by inverting a
large glass jar of 6.75 in Dia.and 12in. high. The jar is fixed to a wood base of 12in. dia which must be mounted
on an equatorial plane (not included). The gnomon is a vertical rod mounted on the long axis of the jar. The scale
is hand written on white card and fixed to the inside of the jar. The time lines are marked in LAT and LAT +1 hour.
Declination lines are marked in 2 Deg. intervals, indicated by the shadow of the tip of the gnomon. They intersect
vertical EQT scales on each side of the main scale. The wood base has a pivot hole and a scale +/- 60 ins on the
rim enables the instrument to be rotated to apply the days correction so that clock time is read from the dial.

Universal Equatorial Dial No. 2 |
| |
Signed and dated. Motto "Tempus Fugit" 1991.Varnished
plywood frame, with varnished card scales showing LAT and LAT + 1hour in 10 min. intervals. Hand written scale,
dia. is 12in., instrument height 21in. The 14in. polar edges of the scale itself provide a pair of gnomons to indicate
morning and afternoon time. Nodus position is adjustable to allow its shadow to be placed on the scale centre line.
A secondary scale gives, Date, Dec. of Sun and "Seasonal Correction" which are the algebraic sum of EQT
and 2 deg .W. Longitude. There is no equatorial base included, but the instrument obviously requires one and is
designed to be rotated on a pin to allow today's "Seasonal Correction" to be applied to give clock time.
A third scale of +/-60 min. is provided on the rim of the base to allow the whole instrument to be rotated appropriately. |

Horizontal Open Book Obelisk Dial |
| |
This unusual dial was evolved in three stages which resulted in
three dials. ( Described in more detail in BSS Bull 96.1 Page 9 and illustrated in Photos 1, 2, 3.)Dial 1. A horizontal
surface 20 x24 in. with sides 3 in. high. Graph paper dial face is covered with film on horizontal and vertical
surfaces. 3 in. Obilisk gnomon. The delineation and furniture are as follows. In black, Local Apparent Time from
4am to 8pm, Declination in 4 deg intervals, Solstice lines. In red, Altitude of sun in 5 deg. int., Azimuth in
10 deg int. Declination lines identify date and EQT correction on upper limbs. The lines extend across the horizontal
plane and up the vertical edges. Instructions, Motto, signed and dated 1989. |
| |
Dial 2 dated 1990. This is a well engineered card overlay dial
face which fits into the same structure and uses the same gnomon. In this development the dial face is a pair of
inclined planes on which all the previous furniture and delineation is replotted to the same precision. This improves
the readability of all the parameters especially time, as the designer noted. Its appearance caused him to think
of it as an "Open Book". |
| |
Dial 3 In order to reduce the overall size in a NS direction,
an additional inclined card sub face was added at the North end. Where necessary, all the time and furniture lines
were recalculated for this inclined surface. The appearance began to suggest a conical dial face. |

Vertical Open Book Direct South Dial |
| |
This attractive dial can stand on its base on a horizontal surface,
It was designed for Lat 52.3, in varnished plywood, 24x14x8 in. The dial faces are a pair of planes declined 15
deg. E and W., the surface is mm graph paper covered in film. It is delineated in 10 min. intervals and shows both
LAT, (Roman, black) and LAT + 1 hr. (Arabic, red). Gnomon with twin nodii indicate the following lines:- Declination
lines at 4 deg. intervals in green which intersect with Date and EQT correction tables on the side panels, Solstice
& Sunrise lines, Altitude and Azimuth lines in 10 deg. intervals in red. Signed and dated 1990. With motto
"Libra Aperta Omnia Revelat" see photo 4 BSS Bull 96.1 |

Flying Bird Experimental Dial |
| |
This dial is constructed of card which has been part cut and glued.
See photo 6, BSS Bull 96.1, with the designer's description on page 9. It was the final experiment in the open
book style where the shadows of a conventional horizontal dial gnomon and nodus are cast onto two surfaces which
are part of an open book elevated by 20 deg. to the north. Time lines, 4am to 8pm LAT have been marked. However
the designer admits that plotting and calculation were both difficult and tedious, so only the eastern wing of
this elegant flying bird has been equipped with the following heavy furniture lines, Altitude, Azimuth and Declination.
Such imbalance may have led to the accident in which the gnomon beak was damaged. |

Open Book Single Polar Dial No 1 |
| |
Two dial faces 120 deg apart, one AM, one PM, are each delineated
in a polar manner to receive shadows from the edges of a single polar gnomon whose style edges are vertically above
the scale mid point. The dial requires an equatorial plane (not included). Plywood and solid oak construction,
18 x15 x 9 in. Delineation on white card, then plastic coated. Sadly many of the black numerals & scales have
suffered from damp and are now blurred. The leaves carry declination lines in green at 4 Deg. intervals which abut
the Date and EQT scales in the Lamont style so an EQT plus Long. correction may be read from the side scales. The
nodus is well defined. Altitude and Azimuth lines in red at 10 deg intervals. Times are marked LAT, LAT+1. Motto,
signed and dated 1994. see Bull 96.1, page 11, photo 5 |
|
B21
|
Open Book Single Polar Dial No 2 |
| |
Two dial faces 90 deg apart, one AM, one PM, are each delineated
in a polar manner symmetrically about their centres to receive shadows from the edges of a single polar gnomon.
To function, the dial must be fixed to an equatorial plane not included. Plywood and hardboard construction, 18
x15 x 9 in. Delineation on white card, then plastic coated. The leaves carry declination lines which abut the Date
and EQT scales in Lamont style so an EQT plus Long. correction may be read from the side scales. The nodus is experimental.
Times are marked LAT, LAT+1, LAT+ 2 |

B22
|
Open Book Multiple Polar Dial |
| |
This interesting dial is a circular arrangement of 6 identical
polar dials, where the edge of the next dial face is the gnomon for the previous dial. Each dial face carries 4
hours marked as LAT and LAT +1 hr. Together the six dial faces cover from 2am to 10 p.m.. Choice of dimensions
and polar rotation of the earth ensure that the next successive dial face becomes active at the required moment
when the previous dial face goes into shade. There is a nodus on each of the leaves. The opposing leaves are all
identical and they carry declination lines at 2 deg Intervals which abut Date and EQT scales in Lamont style. An
axial pivot and rim scale (+/- 60 mins) allows rotation of the whole instrument to give clock time. This dial requires
a suitable equatorial base. Mottoes, signed and dated 1989. Constructed out of plywood, varnished, 9in. x 12in.
