Worked a bit on the manual actuator for the main friction clutch....

Completed the thrust block, two axial bearings, and the two dog-bone clutches....that's about it with respect to the drivetrain.

More work on the drive train and the auxiliary equipment. The air compressor and the main bilge pump didn't have their own motors but were driven by the man drive train. The feed to the pump and the compressor was accomplished by a bevel gear located at the upper main gear. The respective axis was tilted upwards and went through a friction clutch into two additional bevel gears that drove the drive axis of the auxiliary equipment. There were dog-couplings between the respective bevel gear and the pump and compressor. Those will be designed next....
And: I'd need some help. I read that the bilge pump was a Marburg type pump built in the US. I couldn't find anything on that Company or type of pump. Does anyone have material or references on these pumps?

The air compressor and the main bilge pump didn't have their own motors but were driven by the man drive train.I designed the bilge pump (upper right) and the air compressor (lower left) with help of the Lambert plans and very limited additional info. There is one photo showing the edge of the pump and nothing about the compressor. So there is guesswork involved. For the compressor I lent the design of a steam driven compressor of a locomotive. Astonishingly the cylinders fit quite well in the contours shown in the lambert plans....

Progress on the clutch actuator mechanics for the bilge pump and compressor.....The pump and compressor were bolted to the outer hull. These mounts also acted as anchor points for the shafts and levers....intricate design.

More details on the actuation mechanics for the clutches of the bilge pump and the air compressor. The main clutch is a friction clutch and was actuated by the lever in the front. The individual dog bone clutches for pump and compressor were actuated by a shaft-in shaft assembly, with the upper lever actuating the clutch for the compressor and the lower one the clutch or the pump via push rod.

That's it with the drive train, the compressor and the bilge pump. Quite a complex setup for 1901

Final detail on the drivetrain....the circulation pump., I guess for the cooling water. This little pump was driven by the Otto motor via two gear wheels that were connected to the gear on the drive shaft of the combustion engine.

Placed the drive train and the axiliary equipment in the hull. Starts to look like a submarine from the inside. I refer to the open gears as "Crew men mincer".

Andreas, Do any of these early Hollands still exist that can be inspected?Comment

Actually the H.M.S. Holland 1 still exists, hen it was towed to the breakers yeard in 1913, it sank. It was rediscovered years later, raised, restored and is now on dsply at the National Roayl Navy Musem in Gosport

Progress on my 3D CAD model of the H.M.S. Holland 1, the first submarine of the Royal Navy. After completion of the drive train I designed the buoyancy tank in the center section of the boat. It was embedded between the forward and the aft battery tank and the auxiliary ballast tanks on port and starboard. Above the tank were the hand wheels for the Kingston valve operating the tank and some manifolds. All that was located below the floor, and I haven‘t found out yet how they were accessed for operation. Any idea?

Andreas,
Is this by chance the boat you are modeling here?
Your model is going to be another one of your fantastic masterful builds for sure!

yes, that's the one

Thank you, Andreas,
They did look somewhat similar. I am sure the person that did the STL files took some liberty in his design as to its authenticity. Looking forward to seeing your finished build. Thank you for posting up all the great progress photos. I really enjoy following all your builds.
