IMPROVEMENTS IN WATERPROOV OVERCOATS OR COVERINGS TO FACILITATE THE VENTILATION THEREOF
Year: 1880

page_text: LETTERS PATENT to Bernard Birnbaum, of New Broad Street, in the City
of London, Manufacturer, for an Invention of "IMPROVEMENTS IN WATERPROOV
OVERCOATS OR COVERINGS TO FACILITATE THE VENTILATION THEREOF."
PROVISIONAL SPECIFICATION left by the said Bernard Birnbaum at the
Office of the Commissioners of Patents on the 30th March 1880.
BERNARD BIRNBAUM, of New Broad Street, in the City of London, Manufacturer.
"IMPROVEMENTS IN WATERPROOF OVERCOATS OR COVERINGS TO FACILITATE The
VENTILATION THEREOF."
In carrying out my improvements I apply under each arm of the coat or covering
a piece of india-rubber or such like material perforated with several holes of
suitable size, and I form this material with, or I apply to it over the upper side
and down the sides of each hole, a projection, by preference somewhat of a crescent
shape, in order thereby to conduct any moisture away from such holes, and at the
same time to aid in keeping such holes open from being closed by the arms, and
thereby to preserve free ventilation.
To the interior of the back of the coat or other covering I apply an inner lining
of any suitable material with an inner lining to it of horsehair, or other suitable
non-conductor of heat, and with ribs or projections woven thereon in a vertical
direction to aid in keeping open channels between the surface of such inner
lining and the interior of that part of the back of the coat or other covering to
facilitate free passage for ventilation, and across the lower part of the back near the
bottom of this lining, when a lining is used, I form a series of holes (eyclet holes),
and I apply over these holes, on the exterior of the coat or other covering, a band
or fringe loose at its lower edge, just sufficient to prevent rain from flowing to the
interior of the coat or covering by such holes.

"IMPROVEMENTS IN WATERPROOF OVERCOATS OR COVERINGS TO FACILITATE THE
VENTILATION THEREOF."
In carrying out my improvements I apply under each arm of the coat or covering
a piece of india rubber or such like material perforated with several holes of
suitable size, and I form this material with, or I apply to it over the upper side
and down the sides of each hole, a projection, by preference somewhat of a crescent
shape, in order thereby to conduct any moisture away from such holes, and at the
same time to aid in keeping such holes open from being closed by the arms, and
thereby to preserve free ventilation. Figures 1 and 2 show by opposite side views
an arrangement of parts according to this part of the Invention.
a, a, represent the pieces of india rubber or such like material perforated with
holes of any suitable size, holes of the size indicated I have found to answer the
purpose well; c, c, represent the "crescent" projections around each hole for the
purpose of aiding in conducting away any moisture from such holes, and at the
same time to aid in keeping them open for free ventilation.
Across the lower part of the back I form a series of holes 6 with corresponding
projections c, and I apply over these holes and projections, on the exterior of the
coat or other covering, a band or fringe loose to hide these pieces of india rubber or
such like material with their series of holes and projections from view if desired.
Figures 3 and 4 show opposite side views of a similar arrangement to that described
in respect of Figures 1 and 2, but adapted to the lower part of the back of the cont;
Figures 5 and 6 show a section and edge view of the same. In each of these
Figures the same letters apply as in the Figures 1 and 2. In each case the upper
portion of the projections c are broader and project out farther than the points of
the crescent or such like shape formed by the parts c.
Having thus described my Invention, and means which I adopt in carrying the
samo into effect, I would have it understood that what I claim is the improve-
ments in waterproof overcoats or coverings to facilitate the ventilation thereof by
the application to the holes b of projecting pieces c, substantially as described.
In witness whereof, I, the said Bernard Birnbaum, have hereunto set my
hand and seal, this Twenty fourth day of September, in the year One
thousand eight hundred and eighty.
