Hembrug propeller

[gino]

Dear all


I recently acquired this Dutch Hembrug propeller.
Unfortunately the propeller hub has been significantly altered to add a clock.
The propeller was designed for a 80 hp Le Rhone engine.
Lenght 255 cm.

Here the details:

MODEL R
80 HP LE RHONE
D 255

Also a small stamp, showing the Hembrug emblem with 1920 inside.

The propeller looks quite simular to a Levasseur and therefore, I am
wondering if Hembrug build some propellers under licence of Levasseur
or did they used their drawings?
What does model R means?
Could this propeller have been used for the Nieuport 11?

Best regards

Gino

Hoi Gino,

gefeliciteerd met je aankoop. Klopt, het is een Nieuport 11 propeller. Het type is in Nederland in licentie gebouwd door Spyker. Het resultaat was beroerd, veel slechter dan het oorspronkelijke Franse toestel. Hembrug heeft de propellers gemaakt zoals voor veel geïnterneerde toestellen.

I HOPE Gert's response answers your question. I sure as hell don't know what the prop was used on.

Hi Gert

Thank you for the reply.
Do you have an idea about the meaning of the different models used by Hembrug.
In this case "model" R".

Hello Gino and Dave,
I am working to gather more information more information about Hembrug propellers. Even in The Netherlands there is very little known about it. I complete a list of the modelnumbers, and to wich engines (and planes) these propellers were. The firm Hembrug made propellers from about 1915 to 1930, the most in te era 1915 to 1920. Most propellers were substitutes for the interned aircraft made an imergency landing in neutral Netherlands during WW1.

Hi,

Seems to me the prop has the same shape as French Levasseur ones.
Levasseur 2.55 meter length and for 80HP Le Rhône engines were fitted on Nieuport X, Caudron G4 and two seats Morane-Saulnier.

Is "MODEL" written in full or in short? Could you post a clear close-up of the markings?

Regards,
PM

Hi

"MODEL R" is written in full.
Still wondering if the different models where linked to different
engines or maybe pitch.

Best regards

Hello Gino,

That's right, I know that the "model letter" belonging to a type of motor (with corresponding pitch). I've been in touch with the Hembrug museum that has arisen after the bankruptcy of the company. Also they have totally no information about the history of Hembrug propellers.
I be referred to the National Archives in The Hague, where a large part of the estates of Hembrug should lie. (it was a company that only the Dutch army supplied as parts of guns, ammunition, etc.) I hope to find out more.

Greetings Gert
