The Thundersley/AC INVACAR
In 1948 the English motorcycle enthusiast Bert Greeves adapted a motorbike with the help of Derry Preston-Cobb as transport for his paralysed cousin and Invacar Ltd. was born. It's the AC and Thundersley Invacars which are the most famous versions of the 3-wheeled invalid carriages but as the Virtualgaz team explains, the first invalid carriages resembled nothing more than three-wheeled tubs.*




In the early 1920's, Stanley Engineering of Surrey manufactured the bulk of the UK's self-propelled invalid carriages using the 'Argson' brand name. The introduction of the petrol engine was a natural progression as was electric battery power and by 1949, Stanley and other manufacturers like Harding Ltd. and Dingwall & Son had lucrative Ministry of Health contracts.





The first motorised tricycle was powered by a fan-cooled Villiers engine in 1922 while the first ever fully enclosed 198cc version was developed during 1938.






In 1948 Dingwall brought about the flat twin Coventry Climax air-cooled and chain driven go-cart styled carriage as Invacar, Barrett, Tippen & Son, AC Cars Ltd. and George Fitt Motors all gained M.O.H. contracts using mainly the Villiers 147cc power unit.

After some dubious 2-seated versions in the 50's, the M.O.H. standardised its requirements - 147cc Villiers, single seating and steel pressed wheels. Single front wheel drive, hydraulic braking and electric Dyna starting soon arrived.

A 1951 fawn and sage 'Padwin' prototype and the 1949 AC luxury version.

The Harding 'Spinal Carriage' of 1932 and the fibreglass Harper 'Model 55' of 1955.



Mid 50's Invacar 8a Model 52 and the 'Vi-Car' painted pinky-grey and a Barrett Minor.

During the 1960's and 70's the Invacar ruled with its modern fibreglass shell, ice blue colouring and belt drive. Extended wheelbase, a wider track and use of Austin Mini wheels saw the Invacars right through to the end of the final DHSS contract in 1977.

5,928 Invacar Model 67 'Acedes' carriages were built.

A 1966 'Delta' by Frank Tippen Ltd. and the aluminium Invacar Model 57 which was available only in blue with a petrol engine (13,155 manufactured) or the rarer 72-volt electric version - both with sliding windows.

1957 Harper Mk VI with rubber suspension and a 60's Mk12 Invacar with a white roof.

A 1968 prototype Model 70 with the Fiat 500cc parallel twin and 'Denny' Denly MBE, founder of the Invalid Tricycle Association who, on his 1946 Argson Deluxe, crossed the Alps in 1947.

Daniel
Rodd: "My friend Stuart Cyphus runs the 'Invaliud Carriage
Register', which is a special register/page for Invacars and owners in the
Register of Unusual Microcars magazine. He would be very grateful to hear
from anyone who owns a surviving invalid carriage, or anyone who has any
recollections, photos etc. on them. To join the Register of unusual
microcars write to: Jean Hammond, School House Farm, Boarden Lane,
Hawkenbury, Staplehurst, Kent, TN12 OEB. As a member you'll get a
quarterly full colour magazine dedicated to the more unusual microcars,
including seperate pages for different makes in the registers which have
their own registrars, including the Invalid Carriage register. Stuart has
on his register a grand total of 128 surviving road going invalid
carriages (from the 1930's onwards). So the government didnt get them
all!! Many were donated to museums, owned privately (ie were never
government owned in the first place, as up till the mid 60's you could buy
invacars yourself) were not on DSS books, or were"obtained" by
other means, and there are many more out there, I know personally of
someone with 10 in his garden, which have been there 30 odd years.
Basically this means that there are surviving invacars out there and long
may there be, but if you could put the above info on your invacar site
that would be great, and a plea for anyone who owns or knows of any invas
to contact Stuart. All the best, Daniel Rodd (2005). His Contact details

Disability Museum in New York (only museum of its kind in the USA). I can

it]...
Ian Bingle:"Here's a question for you! There was a recording about the Thundersley Invacar. TRUE!! I remember it well, but no-one else seems to! (and I am NOT going round the bend!) I have tried to trace it without success! Have you heard of it? Best wishes, Ian (2004)[Well, we didn't, but we do now, thanks Ian !...3mb of Collapsed Lung's finest moment...]*if the link doesn't work, email me for the .mp3 or search p2p for "Collapsed Lung - Thundersley Invacar".
Ian Bingle: "I have a "street-legal" Tippen Delta electric. I have owned it for about 10 years and I think it may have been part of the manufacturer's batch allocated to the British Legion. My Tippen was manufactured in 1974 and the chassis plate states this. 'Manufactured by Frank Tippen & Sons 1974' plus serial number etc. The problem with all invalid vehicles (and indeed with London Transport buses) is that the year shown may not be the original year as these vehicles frequently get refurbished and re-registered with different bodies etc. This would certainly be true of the later Thundersleys. I believe, however, that my Tippen was genuinely made in '74. Another weird thing is that the fibreglass body appears to be self-coloured in the Ministry blue. And yet it has been re-sprayed a very slightly different shade, which is now peeling off to reveal the original colour! Ian (2004)
John Benson: "Hey there Virtualgaz, You set a hard task (of tracking down a rogue IC he saw in June 2004)... but today I saw our target... after a wild goose chase around Hove (UK) today (spotted the car, but didn't have the camera!) dashed home and went back to Sainsbury's... possibly the first Invacar being tailed too? Anyhow here are some photos, it's taxed too till next year so will prob be with us for a while... Regards John" (July 2004) (brought to you by www.crosscurve.com -making your ideas into reality)...

Ian Campbell: Hi, back in the 70's I worked for a company "Hatherlys" in Footscray, Kent (UK) who had a Ministry contract to service invalid carriages. In the trade they were known as "Cruds". Recovery of broken-down carriages were made with a van towing a two wheeled ambulance, you just picked up the front and dropped wheel into the channel on the ambulance. It was not unusual to be hooted at and told "eer mate it's fallen over". As mechanic's testing carriages, we all had to pass a test - a man from the ministry came, we drove round the pumps on the forecourt and that was it! We had one client who had an AC spinal special (like a stretched limo), he drove it from a prone position. It had a red flashing light fitted incase he got into difficulties. There were still a few electric open (Stanley?) carts around with the tiller steering. Party trick by us naughty lads was to reverse back couple of feet then slam it into full forward. If nothing broke the resulting wheelie was most impressive!!! Best Regards, Ian Campbell (2004)
Dave Price: " I heard there was to be a reunion with all the surviving Thundersley workers this year. Does anyone know anything about it?" Dave Price, ex Thundersley lorry-driver / packer. (2003)
Graham Walker: "HI THERE,I USED TO OWN A MODERN AC INVACAR,TO WHICH I REMOVED THE ROOF,ADDED WIDE ALLOY MINI ALLOYS WITH LOW PROFILE TYRES, ADDED 2 HUGE SPOTLAMPS, PAINTED IT BRIGHT RED, AND WAS EVEN SEEN ON BBC 'TOP GEAR', BEATING A MESSERSCHMITT TIGER IN A SIDE BY SIDE SLALOM RACE!! BELIEVE IT OR NOT I EVEN OUTCORNERED HIM, AND I HAVE THIS ON VIDEO....A GREAT CAR...CHEERS, GRAHAM"(2003).
Dave Price: "I drove the the lorry and trailer delivering Invacars and the Greeves motorcycles for fourteen years. Derry Preston-Cobb (MD) had his own special invalid car with a Greeves racing engine, side mounted. It was a very fast machine and we regulary had to go and rescue Derry when he turned it over trying to corner too fast. When he had to give up this machine, he gave me the engine to fit in my Bond mini-car. The Bond went so fast it frightened me, because the brakes were not efficient enough to stop it quickly. The lorry and trailer carried four cars, two on the truck and two on the trailer. To load the lorry, I had to drive up the lowered trailer tailboard and fast up a steeper ramp onto the back of the truck. The first car was easy enough, but with the second one, I had to brake sharply after speeding up the ramp, so as not to smash into the first one. I had some great times there and still have freinds I worked with". Dave Price (Hedgehog) (2003)
Q. Has there ever been an instance of a stolen Invacar? A. Yes, one of John Curley's customers has had hers stolen twice!
Q. Did you have to be 'disabled' to drive one? A. In the UK, it was the only lawful way.
Q. Is it true that you couldn't legally own an Invacar? A. All Invacars were Government/Council owned.
Q. Is 82mph the absolute maximum aerodynamic speed of an Invacar? A. No, 85mph is the reputed record!
Q. Do they really do 97 mpg? A. No, more like 35mpg in reality.

This is Ian in his 19?? Argson with Jon Heasman who runs a project called GAP (Garnet Access Project) which provides access to the countryside for disabled people. The Argson is being used by Jon to promote the project.

Possibly the only Greeves Invacar in North America? Dan Vitaletti of Colorado, collector of Greeves motorcycles, just had to have an Invacar - so when he saw this one for sale he paid a king's ransom and drove a 2,000 mile round trip to pick it up. It was the only Greeves Invacar imported by the Greeves Motorcycle west coast distributor, Nick Nicholson and is a 1963 Mk.12A (Ser. no. 81618) with a Villiers 11E (617D 2739) having covered a mere 2,219 miles.
This superb 1968 Tippen Delta belonging to A.M. of Massachusetts was originally taken to Nova Scotia by a war veteran. He would like to find out more about the number of surviving TD's and is currently searching for location of the serial number. Any thoughts anyone?
