WILLIAM GUTTENBERG, 14, St. Mary's Street, Bedford, Photographer, I do
hereby declare the nature of this invention to be as follows:-
A means of excluding the admission of air into a receptacle for storing materials
subject to deterioration by contact with moisture e.g. platinum paper used in
photography. This purpose is carried out in connection with platinum paper
by having a cylindrical tin tube open at both ends, and over the ends sliding
lids fit. On the body of the tube where the edges of the lids are against the
body of the tube, hollow beds encircling the tube are fastened, and at the edges
of the lids, flanges having a somewhat curved surface where they would fit into
the hollow beds are fastened. Into the hollow beds a soft fat rubber ring or
rings are placed. And on the lids being fastened by means of pins engaging
slots, the flanges are made to press into the rubber rings and so prevents the
access of air into the tubes.

An Improved Receptaele for Storing Photographic and other Materials
subject to Deterioration by Contact with Moisture.
I, WILLIAM GUTTENBERG, of 20, Queen Street, Lancaster, formerly of 14, St.
Mary's, Bedford, Photographer, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
At
My invention relates to a method of preventing. the admission of air into a
receptacle for the storage of materials subject to deterioration by contact with
moisture. To carry out this purpose a vessel having a sliding lid B in accom-
panying drawing is used, which lid fits over the vessel or tube marked A.
the junction of lid & body of tube round the outside of tube A a hollow bed C
of metal is fastened, into which one or more soft flat india rubber rings G are
laid. On the portion of the lid which would come in contact with the hollow
bed C and rubber rings G a flange D is fastened having a somewhat curved
surface where contact with the rubber ring will be made. On closing the lid
the flange will bed itself into the rubber ring on the catches E & F being made
to engage. Thus the inside of the receptacle or tube will be rendered air tight.

page_text: The catches may consist of pins on opposite sides of flange engaging slots on
hollow bed, or any other suitable means. The contrivance herein described may
be fitted on only one end, or on both ends of the receptacle or tube as may
be desired.
By the herein described contrivance air is effectively excluded from the inside
of the receptacle when the catches are made to engage.
The receptacle is readily opened and closed without the necessity of displacing
& replacing rubber rings or bands which are generally used over the junction
of lid & tube.
By this method of utilising rubber rings, the constant wear & tear on rubber
rings or bands is obviated, and thereby the frequent replacing of them is saved.
Having now particularly described and ascertained the nature of my invention,
and in what manner the same is to be performed, I declare that what
I claim is:
(1) The contrivance of a hollow bed in which a rubber ring or rings is laid,
and a rounded flange bedding into said ring or rings when catches on the
hollow bed & flange are made to engage.
Dated this Six day of December 1899.
