Inclinometer?

[le rampant]

Hello, i found this inclinometer but i don't know if it's for aircraft.
Please can you help me?
Thanks et best regards.

le rampant, it is very neat, but I doubt that it is for an aircraft as it has nowhere near enough range, (4 degrees from level in either direction). Still, it will look good on your desk as a conversation piece.

Cheers!

I don't know though--Elliots were very famous for aircraft instrumentation -----including inclinometers----so I think this possibly is off an 'early-ish' aeroplane...

Could this be from the Elliott of London clock company?

Elliotts already produced tachometers and by 1910 were advertising them for aircraft engines. One used by Tommy Sopwith on a record distance flight to Belgium on Dec 18th 1910 obtained favourable comment from him. The Company expertise in producing barometers, naturally led to the derivative design of altimeters. As early as 1910 a panel of Elliott instruments was being offered as an 'optional extra' by Short Brothers, who had established the first aircraft factory in the world, making aeroplanes based on designs by the Wright Brothers; and Elliott's advertised in early issues of the new magazine 'Flight'( now Flight International). In the August 31st 1912 edition the Technical Editor of Flight Magazine enthused; ‘The widespread increase of this sort of interest in aviation will do more than anything to make rapid progress in design, and I think much might be done by manufacturers to encourage it, if they all made a point of equipping their machines from the start with an instrument board such as is fitted to BE 2, which can, I believe, now be obtained from Messrs. Elliott Bros. The panel includedan altimeter, airspeed indicator, ascent/descent indicator, clock and tachometer.
These interests led to a large production output of aircraft instruments during the First World War. Elliotts supplied airspeed indicators, engine tachometers, clinometers.......

Elliots of Lewisham Kent. I just picked this up off the net

If it can help you, the object is 18 cm long.
There is no number on the scale.
Again thank you for your help.
See you soon,

Le rampant, here is a WWI-style inclinometer fitted to an Avro 504:



And the instrument itself, (with slightly different mounting tabs):

It is very similar to yours. However, from the curvature, this one appears to have twice the range of yours in terms of degrees of incline it could read. So, I am changing my first opinion and saying that perhaps yours is an aircraft item, but more modern. And from the logo style I will guess from the 1940's onward.

Cheers!

May indeed be post WW1---though Elliots were a pre-war company also---but it may be from pre-WW1--or early WW1--were aeroplanes of these days expected to put on much bank----and one could certainly (and did in Scouts---almost ALL the time) exceed the increments on ANY inclinometer....

I certainly see no reason why we should exclude a) Aeroplane use---or b) WW1 type vintage----do 'modern ish' (can't even recall a Tiger Moth, say, even having one) aeroplanes not put on much bank---?

Cheers,
Dave.

Dave, I agree with all your comments. However, there is also an Elliott company that has been making scientific equipment for decades, and one of their product lines are larger portable telescopes, some of which can be fitted with inclinometers for leveling purposes during set up. But I'm still going to lean towards aircraft use on le rampant's, (pun very much intended).

Cheers!

No probs Lou

Would'nt it be great if every artifact just had a bloody date stamp on it

Cheers,
