I am very sorry to have to report that Norman Purves died last night. He had been in a hospice and this was expected, but it's very sad news. Many people will have met him at the Centenary rally at Moreton-in-Marsh, and seen 3 of his cars which were on display there together with David Mawby's collection. He specialised in very early cars and owned the earliest known production car, Chassis No. 71 (the green car), and was still enthusiastically building other early cars almost to the end.

Patents on the Austin Seven |

A book on the history of Wolseley cars by St John Nixon details the early design work on cars by Herbert Austin - for example, the building of his first car in 1895, and what influenced the design. He was aware that its design infringed certain patents, and therefore the whole exercise was kept very quiet at the time.
Later, when the second experimental Wolseley car was built, it was of a very different design. Many of the changes were aimed at getting around patent infringements so that the design might be taken forward commercially. This shows that patents were important in the car industry as early as the 1890s, and that Herbert Austin needed to have them at the forefront of his mind when designing.
Therefore, when it came to the design of the Seven - with its many new features - it makes sense that Herbert Austin was thorough in using patents to protect his design?
I have not looked in detail at the wording of the patents themselves, but anyone in the 1920s wishing to ‘copy’ a Seven would have had to take them into account - and areas listed include frame, suspension, engine lubrication, steering gear, front axle and brakes, torque tube, gear box, radiator and body - so most of the major components.
Perhaps this helps explain why we have that long list of patents on the dashboard of our Sevens?

slack tollerance of new springs and pins |

Hi All,
Well I have the first of my new rear leaf springs fitted - the subject of an earlier post.
A problem of side float has occurred around the spring pin bushes. I have seen articles talking about producing a spacing washer to reduce or eliminate this. Has anyone experience of this and an opinion on whether it is worth it? - the resulting gap is more than 1/16".
The other problem (?) I have also seen alluded to elsewhere - that is the spring pin being forced back outwards when the cotter is fully pressed home. This forces the spring pin back about 3/32" so the large stop on the pin is not against the hub fitting. Should this be corrected or do I live with it?
Any advice would be appreciated.
Do the cognoscenti use proper bearings OR sealed ones?

I have a friend with a late Ruby with a standard engine with late head and a 11/8" SU carburettor which has a GG needle, Is this the best needle for this engine? It starts and runs OK with a high idle speed but on the road my RN will see it off.
