RE: [PIUG List] RE: A search brain teaser for the week-end

Hello,

 

I hope I found the solution:

That’s very interesting story… Please let me cite some more=
 details instead of explanation (source: http://www.mearns.org.uk/stonehave=
n/thomson.htm)

 

Robert William Thomson was only 23 years old when he patented the pneumatic=
 tyre. He was granted a patent in France in 1846 and in the USA in 1847. Hi=
s tyre consisted of a hollow belt of India-rubber inflated with air so that=
 the wheels presented "a cushion of a to the ground, rail or track on which=
 they run". This elastic belt of rubberised canvas was enclosed within a st=
rong outer casing of leather which was bolted to the wheel. Thomson's "Aeri=
al Wheels" were demonstrated in London's Regent Park in March 1847 and were=
 fitted to several horse-drawn carriages, greatly improving the comfort of =
travel and reducing noise. One set ran for 1200 miles without sign of deter=
ioration. However, despite satisfactory testing the tyre developed further =
at this time because the North British Rubber Company was unable to supply =
the strong thin rubber necessary for the inner tubes. For many years Thomso=
n was frustrated by this lack of thin rubber and he turned to the developme=
nt of his solid rubber tyres. It was not until 43 years later that the pneu=
matic tyre returned when it was developed as a bicycle tyre by John Boyd Du=
nlop. Dunlop was granted a patent in 1888 but two years later was officiall=
y informed that it was invalid as Thomson’s patent preceded it.

 

If I am right the the correct answer is:

 

John Boyd Dunlop

4116 (UK) issued March 8, 1889
435995 (US) issued September 9, 1890

 

Patent of Dunlop was invalidated by earlier patent of Robert William Thomson

 “Improvements in carriage-wheels”

US patent 5104, issued 1847

British patent 10990, issued 10 Jun 1846

FR patent ???

I give up with exact French number… Only date 1846 appears everywh=
ere..

I suppose it can be mentioned in article http://www.jstor.org/pss/2596830 b=
ut unfortunately I don’t have access to all JSTOR resources.

 

Best regards,

 

Agnieszka Gorak-Marecik

Kris,

This is unfortunately not the patent referred as "ours" in the <http://www.=
ipr-helpdesk.org/newsletter/37/html/EN/espacenetQuiz.html> text.

Some hints:

- Using the right strategy you will have no doubt about the result.

- Finding the relevant record requires more inspiration than online perspir=
ation.
