As a still photographer,
Alfred West had made a number of inventions to
improve the capacity of the plate camera to take instantaneous pictures in
a seaway. These included a home made instantaneous
shutter and mounting for steadying his unweildy camera at sea.
The 'Our Navy' Cinematograph
company made very rapid progress from 1897, and by April 1898, this Patent
Application was being made by James Adams - who it is believed was part of
the extensive staff who worked with Alfred West in Southsea.
It
is reported that around 50 people were on Alfred West's staff after only
two years in the business. It's assumed that the patents
claimed by the early developers like R.W.
Paul and the Lumière
brothers of 1895 were proving restrictive in terms of licensing and
development of equipment, and that this patent might have sought to get
round some of those - or indeed, used to assert the rights to a genuinely
new feature.

Russell Baldwin writes:
"We can now assume that the model of the lone "Jack of all
trades" involved in the artisanal and cottage industry is not
appropriate here. For instance we know that West had sometimes as many as
fifty people working for Our Navy Ltd. These included managers (Waller
Jeffs), Lecturing Assistants (Captain R.E Edwards. R.N retd), his
assistant C.P.0 MacGregor (ex H.M.S Vernon) who took the cinefilm on the
Ophir cruise, his country-wide publicity agents, another cameraman James
Adams who patented a cinematograph that he invented (No 9738 on 28 April
1898), all the printers, developers and office staff at the ‘cottage’
in Villiers Road Southsea and the office staff and projectionists at the
Poly. The sense of the auteurist individual that we get from the newspaper
adverts, i.e West’s Our Navy is undermined by the obvious scale of
operations of Our Navy Ltd. Whilst we must realize that these operations
were still of the cottage industry mode of production, the scale of this
mode was nevertheless extensive. Whilst it is difficult to gauge the
extent of the input of the other members of Our Navy Ltd in terms of the
production of ideas, it seems clear that the phenomenum. of ‘Alfred West’
was more than merely the one named person, but an amalgam of people who
were all caught up in the emergence of film and played a part in it."

Non-Inflammable Acetate Film Emulsion
in 1910, a new, patented,
non-inflammable, film format ‘BOROID’ was presented to the British
cinematographic trade using acetate-based cellulose.
More details of West's close involvement in testing the new safety emulsion1910 are discussed in more detail on a separate web page.

N° 9738 A.D.1898
Date of Application, 28th
Apr,.1898
Complete Specification Left; 28th Jan., 1899 - Accepted, 8th Apr., 1899
PROVISIONAL SPECIFICATION .
Improvements in and relating to Cameras and Projecting
Apparatus for Kinematograph Pictures.
JAMES ADAMS, 15, Ashby Place,
Osborne Road, Southea, Photographer,
I James Adams, do hereby declare the nature- of this invention to be as
follows:-
In my improved apparatus, the
sensitized ribbon (which is perforated at the edgis to engage with teeth
on a driving drum) is drawn from a spool and passes through a regulator,
which is placed opposite an exposing aperature, and thence on to the
driving drum above mentioned. .
'Between the regulator and the
driving drum is a roller mounted eccentrically on a revolving disc, which
roller alternately engaging and releasing the loop of sensitized ribbon
between the regulator and driving drum, gives to the ribbon an
intermittent step by step motion.
My improvement is in and
relating to the regulator and accessories thereto, and is designed for
securing perfect registration of the pictures photographed on the
sensitive ribbon, so that (each picture shall stand in the same definate
position in relation to the perforations in the edgis of the ribbon.
To secure this result I place
between the store spool and the regulator a clutch through which the
ribbon passes and which acts intermittently on the same.
Then between this clutch and the
regulator I place a roller mounted in a swing frame which is held in
position against a stop by a spring.
In the regulator are teeth which
engage in the perforations at the edges of the ribbon and act in the
manner of a pawl, allowing the ribbon to pass freely in one direction
(i.e. that in which it is drawn by the driving drum) but preventing motion
in the reverse direction by engageing in the perforations in the edges of
the ribbon.
To use my apparatus the ribbon
is wound on the store spool and placed in position in the camera. The end
of the ribbon is then passed through the clutch, under the roller in swing
frame, thence through the regulator, round the eccentric roller, and
engaged by means of the perforation on the driving drum.
The action will then be as
follows,
The driving drum being turned
drives the ribbon .forward at a uniform speed l but the eccentric (being
geared to the drum) alternately engages with and releases the' ribbon,
giving it a step by step motion.
Just before the end of the
stroke of the eccentric the clutch above mentioned grips the ribbon- and
holds it fast. The ribbon becoming taut lifts the swing roller against the
action of the spring, and on the eccentric completeing its stroke and
releaseing the ribbon the latter is drawn back or retrograded by the
action of the spring acting on the swing roller till it is stopped by the
teeth in the regulator engaging, in the perforations in the edge’s of
ribbon.
This slight retrograde motion of
the film by which it is brought to rest by means of the pawl like teeth in
regulator engaging in the perforations constitutes my improvement.
Impts. In Cameras and Projecting
Apparatus for Kinematograph Pictures
exposure or projection the
ribbon of film in cameras and projecting apparatus for kinematograph
pictures.
2. The use of an intermittent
clutch action in conjunction with a roller mounted on an arm and
controlled by a spring so as to produce the short retrograde motion in the
ribbon of film by which the perforations near the edge are engaged and
firmly: held by ratchet teeth.
3. The combination of clutch,
spring roller and ratchet teeth in the manner and for the purpose
described in this my application.
Dated this 27th day of January 1899.
JAMES ADAMS.
