Projector Drive Belts for 8mm, 9.5mm, & 16mm projectors
Charles Pathe
 Died 25th December 1957
on his 94th birthday
Pathé made a first attempt at home cinema in 1911 - this was 28mm
The film had  three perforations on the left, and one perforation on the right side per frame
A feature of the 28mm K.O.K. projector  was that it had dynamo lighting  
supplying a voltage to a 6volt  projector lamp
A clever idea as a lot of buildings at this time only had gas lighting
The 28mm KOK system proved a commercial success - not only in the home, but in schools, churches and clubs
By 1918 over 10,000 machines had been sold and over
25,000,000 feet of positive film had been produced
 During World War 1 production of 28mm equipment in France ceased
The gauge continued in the U.K, the USA and Canada
All production stopped in 1920

The 9.5mm film gauge, was introduced at Christmas 1922 in France with a hand cranked projector the

By means of notches in the film a mechanism was set into motion in the projector by which certain images - titles or close-ups - could be frozen for a few seconds.

The following year the Pathéscope company in the UK (who had previously imported Pathé phonographs, record players and the early and bulky 28mm KOK movie projector) launched the same projector

 Soon a matching hand-turned camera arrived and 9.5mm movies were here to stay!

The 9.5mm home movie gauge was more popular in the UK than France
This was probably because in the 1930's (the boom time for 9.5mm) the UK had more disposable income and 9.5mm sales were probably highest in the UK
Certainly it would appear so from the volume of 9.5mm films and equipment still turning up today in the UK
