Spirit Level & Maps

     

An effort has been made to transcribe relatively recent documents of Daniel Christiansen's manuscript. The pages provided hints at a novel navigation system for a flying craft. The full text so far can also be found here Page 210 & 211

Before reading, take a look at this simplified rendition of the concept within:

"The Craft makes...

Decrease liquids pressure...

Consequently the bead will tend to move towards inside of curve.
 

However, the corresponding degree of movement of the liquid will be negligible because the spheres constitutes a non-pendulous and balanced body except for the difference the displacement of the bead makes."

...[deter]mined visually by the aid of suitable instruments located with the horizontally stable base of the compass; however it may also be determined by means of a tiny air-bubble (bead formed by vacuum) floating on the liquid contained between the globe and the transparent first, spherical gimbal. Provided this spherical gimbal is a sufficiently true sphere; the little spirit level like "bead" will give a true and ever ready indication of the position of the instrument with respect to the earth. In fact the bead will not also indicate position, but also the speed and the direction of the vessel or aircraft employed.

 "Displacement of Liquids - Mounting Heavy Gyro-Globe & Suspend it With Ease

Aside from serving the purpose of a "spirit level", the liquid placed between the [supportive] transparent spheres (inner spherical casing or housing, revealing map globe, first spherical gimbal, second spherical gimbal.) also serve to support the weight of the heavy inner gyroscopic unit, or the sphere containing all the active elements. Thus the pivots of the gimbals may be relieved of any undesirable stress and friction, together with permitting the adoption of gimbals of comparatively light construction, the types of liquid should offer minimum of friction.

The weight and displacement of the heavy inner casing, containing the gyrosopic mechanisms, may be so adjusted that the sphere will just about sink under in the liquid it displaces. In other words, the weight of the sphere should displace a volume of liquid about equal to its own volume."

It works because the globe on the inside will remain stationary, and while a vessel travels about the circumference of the Earth, the compass mount and air bead will move relative to the globe.

...

Perhaps this is why Daniel was constructing spherical globes and had a variety of map images.
