Garrett Displacement Lubricator
 

Wanted - 2 Garrett design displacement lubricators

(had an ad with picture on the old site, any chances of finding the picture David I believe its hosted on the ttu site)

Wanted - Drain Tap Valves for a Garrett

Still looking

Still looking, or does anyone have a drawing for these? I am led to believe it cannot be found/is missing at Ipswich

Sam's Boy's Burrell has one, but that was late on - close to Garrett takeover.

Would it be worth checking any Burrell archives?

According to Garrett specification No. 259 for the 4CD tractor the displacement lubricator was detailed on drawing SD 704. I believe SD stood for Standard Detail. In my search through the Ipswich archives I have not located many SD drawings of any description. Presumably as these were standard bought in items it wasn't considered worth retaining the SD drawing.

I am also after such a displacement lubricator so if any one comes across a brace of them please let me know.

Sorry for gate crashing your wanted advert Mr Steam Jnr

Ok, I believe this to be a shiphams fitting. I have seen in 2 sizes. Burrels list at least two sizes on spec sheets.

The outline drawing does exist at garretts. But it does not show the internals.
Reading have no drawings of this type for burrels.

I too need one if these... I plan to make one at some point.

Garrett spec states size as 1/2" x 2".

These are obviously much in demand. I hope Sam Boy's lubricator is screwed down very tightly.

I belive Mr Steam Jnr was also looking at having some made.

The late built Burrell roller "Hero" also has one. Having had one apart, I know what they look like inside, and can provide a sketch if you need some clues, but as for exact dimensions you will have to measure one. The 1/2" in the spec above will probably refer to the BSP thread size (male parallel) which is where it connects to the steam chest. The top of the body, (which is a casting but machined on the outside), has a "three leaf" interrupted flange facing outward, corresponding interrupted flange on the cap facing towards the centre, so that a part turn engages the flanges and prevents the top coming off. The top of the body is closed off except for the centre filling hole (about 1" diameter) and this hole sits at the centre of a slight depression machined into the top surface of the body. An inverted mushroom shaped piece of gunmetal is connected to that threaded spindle you can see coming through the cap, so that as it is tightened, it pushes down onto the edge of the filling hole in the upper face, sealing it against steam pressure and loading the flanges. The rest of the lubricator is standard practice, a pipe inside coming up close to the top, and regulated at the base by the feed adjustment screw - just a needle valve with a typical stuffing box, and the drain is very similar on the other side - from memory the condensate just trickles out of a weep hole in the drain stuffing box body. The two wheels engage on small squares on their respective shafts and from memory the nuts on the end of the shafts are 3/8 whit, the squares being 3/8 A/F. I think the thread in the top cap is 1/2" whit.

Thanks for all the replies, will have to decide on the best way forward
