So what exactly is a slow pressure oxygen system and what does it fit on?? What is a Valve Check, and why did Grandpa have loads of them????
****Update 25/2/10 - from an anonymous poster - many thanks ! The boxes marked Schrader have WWII US Army Air Force markings on them and probably had something to do with military airplanes. Hamilton Beach made propellers for the planes.
Having not seeing what the part looks like, hard to tell more about it. Schrader made parts for tires. Of course, during WWII, Us companies made parts for all sorts of things for the war that they were not known for making.And indeed they are for aircraft systems - ties in with the fact he has bucketloads of military aircraft parts...
Yikes ! This looks rather unpleasant !!!! The glass is quite thick and the length of the tube is about 3 ft. There must be over 100 in boxes. Could it be something from chemistry or physics? Or something else?
This is a strange one. There are numerous wooden crates full of these ceramic pipes. The top part is smooth as is the very bottom but the rest is rough. There would be loads of them but I cannot see any markings to give any clue as to what they are. Possibly electrical, maybe railway related???
***Update 25/2/10 - anon poster says The ceramic pipes may be for use as insulators when running telephone wires through walls. They made them for that purpose in the early 1900s. The telephone bloke would drill hole in wall, insert one of the insulators and feed the wires through the insulator. Most walls were just thin wood, so the insulators did not have to be long. They did not insulate walls and make them thick back then.
I think this is indeed correct ! Thank you kind person for the info, its much appreciated !
Speaking of rail related
Is it a relay system? Why is it rail related? The badge says Victorian Railways Electrical Engineering Branch , Spencer St, Melbourne. But what did it do??
The case for it is really quite pretty - the unit is quite heavy and the base is wood.
?????????????? Its got to be part of one of the phone exchanges, but what part exactly ?
Thats it for Day One. Stay tuned and please pass this around to anyone you know who may be able to help..
The schrader valve is for blowing up car or bicycle tires, depending on the actual valve.
ReplyDeleteHey Ewan... what an awesome project! Sounds like fun! Kind of like archaeology but without the dirt. I am interested to see what else you might pull out of this shed!

ReplyDeleteThe glass tubes look like chemistry pipettes. when I was doing chemistry at school, we had a rubber ball like device to attach to the top which could be compressed to generate suction, but I guess when these were used, H&S didnt need such things!
