Royal Ruby motorcycles were built from 1909 at Cannel St , Ancoats (Manchester) factory which had previously only been making cycles (Ruby Cycle Co.). They were relatively successful though expensive and ambitiously tried to make as much as possible on site, though the engines were JAP or Villiers with the 'Royal Ruby' name cast on, and the sidecars probably bought in from Mills Fulford

A wide range of models were advertised (in 1914) from 250cc 2-strokes and 4-strokes to 3, 4,5, 6 & 8hp twins as well as a 'Ladies Model' with dropped frame. 

Financial trouble arrived in 1919-20, possibly as a result of non-payment for a large batch of machines delivered to the Russian Government in 1916. A second batch were dispersed on the home market but that was rather flushed with ex-wd machines in 1919 and losses were inevitable. The assets of the bankrupt company were acquired by a new board which included some of the original management and a new factory was founded on Moss Lane Altrincham where production of an entirely new range with an 'Indian' (or possibly Beardmore)-inspired sprung frame began in 1921. 

Again the market was not impressed by value and only a small number were sold before the firm again went bust in 1922 and was offered for sale as 'a going concern ' on Dec 12th.  Some assembled machines appeared in ads in 1923-24 but the name was bought by Albert Horrocks of Bolton in 1927 and he started with a completely new saddle-tank machine for the 1928 season with bought in Villiers and JAP engines and Albion and Sturmey gearboxes. The only unusual feature was extra double stays either side of the front down tube which had dubious technical advantage. 

Having also advertised a 3-wheel cyclecar under the Royal Ruby name in 1927, this enterprise was left to it's designer Maurice Edwards (there is no evidence that more than a prototype was made) who manufactured small numbers to his design under the 'MEB' brand name.   There is no evidence that motorcycle production carried on after 1931, though occasional adverts in the trade press suggest that odd machines may have been assembled from remaining spares up to 1933. There are around 15 survivors worldwide, mainly from the prolific Ancoats period.

I am happy to attempt to answer any queries.

Tragatsch give years as 1909-1933, and says that the marque used engines of its own manufacture as well as JAP singles and V-Twins, and Villiers two-strokes. The fact that Royal Ruby incorporated its own castings onto proprietary engines explains this error.

ROYAL RUBY LIGHTWEIGHT
You might be interested in my 1913 Royal Ruby Lightweight. The frame no is stamped on the inside of all 4 engine mounting plates and is 32. The 269c.c. engine is from the first ever run of Villiers 2 strokes and is no O 969. It goes like a rocket- no clutch, no gears, and only a rear brake. I will help any other owner with info.
