399 forum posts 167 photos | Hello, Recently bought this compressor and wondered if anyone can identify it from the pics? Quite well made, 40mm bore x 35mm stroke, splash lubrication but pumped from a lower reservoir by an oil pump on the end with what looks like an adjustable oil pump. The compressor isd in good condition, sized as the oli appears to have turned to varnish! Thanks Peter

399 forum posts 167 photos | Thanks for the replies. I thought it was a bit odd with British, Belgian, French & Italian patent numbers, no USA or Germany. Also there seems to be a lot of pattern numbers all over. Is the patent date the last part of the digits? ie 22 Could be Westinhouse but isn it a bit small for a train compressor? Dont know anything about refrigeration compressors, what gas would it be compressing of that era, A better pic of the end, rather strange logo?

From http://www.refrigeration-engineer.com/forums/archive/index.php/t-5917.html "An old timer who used to work on Cental refrigeration systems that were popular in apartment buildings, told me a story where there was a leak in a coil in an apartment refrigerator, the Sulfur Dioxide bleached all the veggies and fruit white, preserved them quite well, but took out all the coloring." "Many years ago my Dad had a old refrigerator that failed. He went and bought a new one.
Other gems at that link! Neil |

... Is the patent date the last part of the digits? ie 22 . Peter, Typically, yes ... and this appears to be the relevant GB patent. MichaelG. |

![]() 5068 forum posts 3 photos | OK guys it's a basic standard Westinghouse twin cylinder compressor, fitted in the tens of thousands to Fodens, AEC's Gardner's, Leylands, Scammell's etc as an air brake compressor but in that guise they didn't have the sump part, just a plate with a return path to the engine sump and the oil pump was also omitted and it relied on a feed from the main oil gallery on the engine.
So quite what this one was used for I personally don't know but I have worked on many of these truck derived units. |

399 forum posts 167 photos | Thanks for the replies. The patent is an individuals name(Charles Henry Dyke) rather than a company. Is that standard practice? But it does describe the oil pump fitted to transfer oil between the chambers. Agree John it does look like an automotive compressors but the familiar ones are larger and use the engine lubrication system rather than splash, also have unloader valves in the head. I have a water cooled version on my lorry. I have seen Gardner engines from the 1930's and 40's with small single cyl compressors for the air assisted braked fitted then before full air brakes came in in the 1960's so it looks like its probably an early Westinhouse automotive compressor and from the patent 20's or 30's Peter

![]() 96 forum posts 24 photos | This could well be Routemaster or RT/RF compressor which had remote unloader valves and were splash fed with SAE30 oil, these vehicles were mainly fitted with Westinghouse air systems. I worked on these vehicles for many years. The compressors were belt driven from the carden shaft between engine and gearbox with 2 or 3 belts so the pulley may not be the original one. Ah memories |

Peter, It's by no means uncommon In many cases, however, the inventor is named but the applicant is a company. If you find patents interesting, it's well worth playing with the advanced search facility on espacenet. MichaelG.
