IMPROVEMENTS IN FABRICATING AIR OR WATERPROOF ARTICLES
Year: 1876

page_text: LETTERS PATENT to John M. Macintosh, of Wilson Street, Finsbury, India-
rubber Manufacturer, and William Boggett, of Chelsea, both in the County of
Middlesex, for the Invention of "IMPROVEMENTS IN FABRICATING AIR OR
WATERPROOF ARTICLES."
Sealed the 23rd March 1877, and dated the 28th September 1876.
PROVISIONAL SPECIFICATION left by the said John M. Macintosh and William
Boggett at the Office of the Commissioners of Patents on the 28th September
1876.
JOHN M. MACINTOSH, of Wilson Street, Finsbury, India-rubber Manufacturer, and
WILLIAM BOGGETT, of Chelsea, both in the County of Middlesex. "IMPROVEMENTS
IN FABRICATING AIR OR WATERPROOF ARTICLES."
The object of our Invention is to fabricate cushions and other air and waterproof
articles by means of an inner air and waterproof vessel or case strengthened by an
outer covering of other materials.
According to one method of carrying out our Invention we usually make the
inner vessel or case by laying a sheet of india-rubber on a bench, upon which wo
place a second sheet rather smaller for the purpose of making a secure joint by
overlapping. The intended position of holes to receive metal eyelets are then
marked, at which points discs of solutioned rubber are placed for some purposes
between the two sheets, and holes are punched through them and the sheets. A
short piece of rubber tube is placed in each hole, the ends of the tubes being turned
down to prevent the escape of air or water. When so far completed (with a valve
for filling with air or water) the vessel or case is vulcanized in the usual manner.
The outer covering (which may consist of textile fabrics, leather, or other fit
materials) with holes corresponding to those in the rubber sheets is placed so as to
envelope them, the eyelets are then placed in the holes and fastened so as to hold
the two cases together, the edges of the outer one being sewn together.
In some cases we employ a textile fabric made air-proof by dissolved rubber or
otherwise in place of sheet rubber for making the inner vessels.
In place of eyelets being employed to secure the inner and outer cases together at
intervals, tabs, tufts, or other means of fastening them together may be employed.

the said John M. Macintosh and William Boggett in the Great Seal Patent
Office on the 28th March 1877.
JOHN M. MACINTOSH, of Wilson Street, Finsbury, India-rubber Manufacturer, and
WILLIAM BOGGETT, of Chelsea, both in the County of Middlesex. "IMPROVEMENTS
IN FABRICATING AIR OR WATERPROOF ARTICLES."
The object of our Invention is to fabricate cushions and other air and waterproof
articles by means of an inner air and waterproof vessel or case strengthened by an
outer covering of other materials.
According to one method of carrying out our Invention as shown in the Drawing
hereunto annexed, we usually make the inner vessel by laying a sheet of india-
rubber A on a bench, upon which we place a second sheet of india-rubber A¹ rather
smaller for the purpose of making a secure joint by overlapping. The intended
position of holes to receive metal eylets B are then marked, at which points discs
of solutioned rubber b are placed for some purposes between the two sheets, and
holes are punched through them and the sheets. For some purposes a short piece
of rubber tube is placed in each hole, the ends of the tubes being turned down to
prevent the escape of air or water. When so far completed (with an opening for a
valve F for filling with air or water) the vessel or case is then vulcanized in the
usual manner. The outer covering E (which may consist of textile fabrics, leather,
or other fit materials) with holes corresponding to those in the rubber sheets is
placed so as to envelope them; the eyelets B are then placed in the holes and
fastened so as to bold the two cases together, the edges of the outer one being sewn
together.
In some cases we employ a textile fabric made airproof by dissolved rubber or
otherwise in place of sheet rubber for making the inner vessels.
per-
In place of eyelets being employed to secure the inner and outer cases together at
intervals, tabs, tufts, or other means of fastening them together may be employed.
Having thus described the nature of our improvements and the manner of
forming or carrying the same into practice, what we claim is, the method of making
air or water proof goods or articles with two cases A and E held together, sub-
stantially in the manner and for the purposes herein-before described and represented
in the Drawing hereunto annexed.
In witness whereof, I, the said William Boggett, have hereunto set my hand
and seal, this Twenty-seventh day of March, in the year of our Lord One
thousand eight hundred and seventy-seven.
WILLIAM BOGGETT. (L.s.)
