A Combined Timepiece, Compass, and Shadow-bar for Use by
Seamen and others.
I, RICHARD ROOD, of the Yacht " 'Dogstar" Fay's Yard, Northam,
Southampton, Seaman, 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 a combined timepiece, compass and shadow or azimuth
bar for use by seamen and others.
According to my invention I apply a compass to the back of a watch by suitable
means, the watch being so constructed as not to be affected in any way by the
needle of the compass.
I also provide in combination with the compass a shadow-
bar designed to cause a shadow to fall on the compass card whereby it can be used
for ascertaining the azimuth of the sun.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which:
11
Figure 1 is a plan of my combined time-piece, compass and azimuth bar:
Figure 2 is a sectional elevation of the same, the section being taken on the
line 2-2, Figure 1:
Figure 3 is a similar view to that shewn in Figure 2 shewing a modified form of
shadow or azimuth bar.
For the purposes of clearness the several figures are drawn to an exaggerated
scale.
a is the non-magnetic timepiece or watch the back of which is provided with a
pin on which is mounted the magnet c carrying the card d. e is the casing
enclosing the said magnet c, and ƒ the glass or other cover of the same.

page_text: g is the shadow or azimuth bar which, as shewn in Figures 1 and 2, is of semi-
circular form, pivoted at its two ends and arranged outside the casing enclosing the
magnet, and in Figure 3 in the form of a simple bar fixed inside the said casing.
In Figure 1 the shadow-bar is shewn in the position into which it is turned when
the instrument is placed in the pocket, whilst in Figure 2 the dotted lines shew the
same raised in position for use.
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 :-
The combination with a non-magnetic timepiece of a compass and an azimuth or
shadow-bar substantially as, and for the purpose, described.
Dated this 11th day of July 1895.
