Ships' Compasses, Chronometers, and the like.
I GEORGE CHARLES LILLEY of 10 London Street Fenchurch Street in the City of
London Compass Maker do hereby declare the nature of this Invention to be as
follows:-
My Invention has for its object to support ships Compasses Chronometers and the.
like so as to neutralize or counteract the effects of vibrations incident thereto when
employed in steam ships or other vessels or vehicles. In carrying out my Invention
with reference to a ships compass I support the Gimbal of the Compass box in
bearings supported or mounted on springs or yielding surfaces carried on the band or
suspension ring so as to admit of the Compass box rising and falling to accommodate
itself to any vibrations to which it may be subjected. The said bearings being fitted
to move in or upon guides carried by the said band ring or attached to the turntable
in which the Compass is mounted so that the point of suspension is maintained in the
plane of the Compass pivots at all times. The band ring may be suspended in the
binnacle by means of india rubber bands as at present or be otherwise suspended if
desired.
The spring bearings or yielding surfaces hereinbefore referred to may if desired be
attached to the Compass box to receive and support the pivots attached to the gimbal
or the bearings or yielding surfaces may be attached to the gimbal to receive and
support the pivots carried on the band ring.
It is obvious that Chronometers and like instruments may be similarly mounted so
as to neutralize or counteract the effects of vibrations.

I GEORGE CHARLES LILLEY of 10 London Street Fenchurch Street in the City of
London Compass Maker 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:-
My Invention has for its object to suspend or support ships compasses chrono-
meters or the like so as to neutralize or counteract the effects of vibrations in steam
ships or other places where the compass or the like is situated. I will describe the
Invention as applied to a Ships compass from which its analogous application to
chronometers or like objects will also be understood.
According to my Invention I support the compass bowl or the gimbal ring of the
compass in bearings sustained by or mounted on springs or yielding devices so as to
counteract or intercept vibrations and prevent them, or in great part prevent the said
vibrations from being conveyed to the compass card and so that the point of suspension
of the compass card is maintained in the plane of the Compass pivots at all times or
practically so.
In order that my Invention may be well understood I will explain with reference to
the accompanying Drawings what I consider to be the best manner of performing the
same with reference to the suspension of a compass bowl and gimbal ring on the band
ring from which its analogous applications will also be understood.
Figure 1 is a side view of the apparatus with the binnicle in section and Figure 2
is a transverse section in a plane at right angles to that in which Figure 1 is viewed.
A is the compass bowl having pivots or trunnions a resting at each side in bearings
in the gimbal ring B as usual the said gimbal ring having pivots or trunnions bat
each side each resting in a bearing piece C. These bearing pieces have wing
pieces c which slide upon guide rods d secured in the pieces D secured to the band
ring E. Around the guide rods d are coiled the springs F bearing at their one end
on the pieces D and at their other end upon the wing pieces c. 9 are cross pieces
above the slots in the pieces C and secured by screw nuts g² screwed onto the rods d.
The pieces are preferably slotted at the part which engages with the rod at one
side so that when the screws are slackened the piece g can be turned upon the other
of the rods d to allow the Compass bowl to be lifted out. are India rubber strips
which secure the band ring E to the binnicle J as usual. I do not limit myself to the
precise details shown as it will be readily understood that they may be varied without
departing from the nature of my Invention for example it will be understood that a
similar arrangement of spring devices may be used to take the bearing of the pivots
or trunnions of the Compass bowl in the gimbal ring or of the gimbal ring or the
band ring in the binnicle. It will also be understood that the device may be reversed

page_text: that is to say the pivots or trunnions may be fixed on the binnicle, band ring, or
gimbal ring, or the like and the spring bearings be on the parts whereon the pivots or
trunnions are fixed in the arrangements as hereinbefore described.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is :-
First In the suspending arrangements of compasses chronometers or the like
springs or yielding devices arranged in combination with the bearings of the pivots or
trunnions substantially as herein before described.
Second-The arrangement of spring or yielding devices for the suspending of
compasses chronometers or the like substantially as hereinbefore described and
ilustrated in Figures 1 and 2 of the accompanying Drawings.
