Help needed to identify vert steam engine
Michael S.:
An image from the patent document.
Jasonb:
As they have no drain cocks the spring is a simple way to let the valve lift to let condensate escape without the risk of a hydraulic lock.
Zephyrin:
I also have repaired one of these little machines some years ago, a simpler model than yours, a Bing "Royal" from 1905-1908, yes that old !
For the seals especially the water level seals, which have to be very thin to pass through the nuts, it's possible to use rings cut out from the cheap plastic heat shrink tubing largely used for electronics, seems to be sufficent on these small low-pressure models.
crueby:
Thats quite an interesting valve arrangement! Thanks for showing the diagrams of it Michael!
vtsteam:
Michael, thanks for the patent drawings and advice.
Jason, that makes sense.
Zephyrin, on this model there is a fair amount of clearance in the pass-through hole for the sight glass. In this setup there are flanges on the guard that are screwed into the boiler shell. They trap what was probably once packing or a grommet of some kind (now completely deteriorated). Tightenng the screws probably applied pressure to the packing which then tightened to the glass tube ends, which protrude into the boiler.
