BENJAMIN JOSEPH BARNARD MILLS of the firm of Harris and Mills of
23 Southampton Buildings in the County of Middlesex, Patent Agent A NEW
OR IMPROVED HYGIENIC JOINT FOR DOORS, WINDOWS AND OTHER OPENINGS
A communication to me from abroad by Jacques Couturier of 25 Rue de Sèze
Lyons in the-Republic of France
The Invention is applicable first to all kinds of closing of places of habitation
such as, doors, windows and casements of houses of habitation, doors of carriages,
wagons tramway carriages and other uses and second to the closing of trunks,
cases, reservoirs or receivers of any kind in which no pressure exists.
It has for its object not to close hermetically but to prevent the rapid introduction
of the external air, which can only penetrate into the enclosed space in a slow and
continuous manner, being filtered and deprived of the humidity and injurious dust
which it holds in suspension.
It completely prevents the accidents resulting from currents of air in apartments
and carriages of every kind, and suppresses, for habitations the inconvenient
and costly employment of bags or cushions which constitute a very imperfect
obstruction.
It consists in principle in the employment of bands of felt or elastic material
such as cloth, caoutchouc, leather, cork, fixed upon a metallic band and pressed by
springs upon the part against which it is required to make joint.
The recess, which receives this band and the springs, can be hollowed out of the
wood itself, it can also be previously made and inlaid in the wood or caused to
project from the same.

page_text: The various examples shown in the accompanying drawings will render easily
understood the means to be employed in all appropriate cases.
The most ordinary joint and which is capable of being previously made in
quantities is composed as shown at Figures 1 and 2 of a hollow receiver A of metal
or other suitable material, the section of which can be made of various forms but
which should be provided on its face with two flanges a. a. intended to retain the
plate B upon which is fixed the elastic joint C.
Springs D fixed at convenient intervals hold the plate B pressed against the
flanges a. a. whilst the door is open.
These springs can be replaced by a continuous undulated plate; this joint can be
let into the door posts as shown at Figure 3 or placed on the interior thereof by
means of angle irons as shown at Figure 4.
For folding doors the joints can be made double as shown at Figure 5.
The wood itself may also be hollowed out to receive the springs and in this case
as shown at Figure 6 and in order to obviate the flanges a. a. the elastic band can
be fixed on the side of this recess.
These various examples are applicable to joints where the door closes against
parts or projections capable of carrying the flexible joint or of receiving pressure
when the latter is fixed upon the door.
For the joints of the bottoms of doors and other analogous places which have no
projecting parts the elastic band is fixed below the door, in order to prevent its
rubbing upon the ground it is held raised during the motion of the door and
descends upon the sill or threshold only at the moment of complete closure.
Figures 7, 8 and 9 represent this arrangement. At the bottom of the door is fixed
the metallic cage A serving to receive the elastic furniture C which is carried by a
metallic band B, the section of which has the form of a reversed U. Upon the
back of the latter are fixed by their centre the springs D. D. which may vary in
number; each of these springs is fixed, by the end next the shutting post of the
door to a slide E terminated on the same side by an inclined plane b; the other
ends of the springs abut against fixed points d. d. belonging to the cage A.
When the door is open, the elasticity of the springs pushes the slide E outwards
and holds the elastic band in the interior of the cage as shown at Figure 7 so as
not, to interfere with the play of the door; but at the moment of closing, the
inclined plane b comes against a similar inclined plane e fixed to the shutting post
or to other projection or fixture capable of operating the slide E'; the slide is then
pushed back, the curvature of the springs increases, and the joint descends outside
its recess to press upon the sill or threshold, as represented at Figure 9. These
various examples show sufficiently how the hygienic joint can be applied in all
cases.

" A NEW
OR IMPROVED HYGIENIC JOINT FOR DOORS, WINDOWS AND OTHER OPENINGS,"
A Communication to me from abroad by Jacques Couturier of 25 Rue de Sèze
Lyons in the Republic of France
The Invention is applicable first to all kinds of closing of places of habitation.
such as, doors, windows and casements of houses of habitation, doors of carriages,,
wagons, tramway carriages and other uses and second to the closing of trunks,
cases, reservoirs or receivers of any kind in which no pressure exists.
It has for its object not to close hermetically but to prevent the rapid introduction
of the external air, which can only penetrate into the enclosed space, in a slow aud
continuous manner, being filtered and deprived of the humidity and injurious dust,
which it holds in suspension.
It completely prevents the accidents resulting from currents of air in apartments
and carriages of every kind, and suppresses, for habitations the inconvenient'
and costly employment of bags or cushions which constitute a very imperfect
obstruction.
It consists in principle in the employment of bands of felt or elastic material
such as cloth, caoutchouc, leather, cork, fixed upon a metallic band and pressed by
springs upon the part against which it is required to make joint.
The recess, which receives this band and the springs, can be hollowed out of the
wood itself, it can also be previously made and inlaid in the wood or caused to
project from the same.
The various examples shown in the accompanying drawings will render easily
understood the means to be employed in all appropriate cases.
The most ordinary joint and which is capable of being previously made in
quantities is composed as shown at Figures and 2 of a hollow receiver A of
metal or other suitable material, the section of which can be made of various
forms but which should be provided on its face with two flanges a a intended to
retain the plate B upon which is fixed the elastic joint C.
Springs D fixed at convenient intervals hold the plate B pressed against tho
flanges a a whilst the door is open.
These springs can be replaced by a continuous undulated plate or by wire
springs, and in general by all kinds of springs capable of pressing upon the plate B,
this joint can be let into the door posts as shewn at Figure 3 or placed on the
interior thereof by means of angle irons as shown at Figure 4.
For folding doors the joints can be made double as shown at Figure 5; in this
case the band of felt will be raised upon one of its edges.
The wood itself may also be hollowed out to receive the springs and in this case
as shown at Figure 6 and in order to obviate the flanges a a the elastic band can
be fixed on the side of this recess.
These various examples are applicable to joints where the door closes against
parts or projections capable of carrying the flexible joint or of receiving pressure
when the latter is fixed upon the door
For the joints of the bottoms of doors and other analogous places which have no
projecting parts the elastic band is fixed below the door, in order to prevent its
rubbing upon the ground it is held raised during the motion of the door and
:

page_text: descends upon the sill or threshold only at the moment of complete closure;
Figures 7, 8 and 9 represent this arrangement. At the bottom of the door is fixed
the metallic cage A serving to receive the elastic furniture C which is carried by a
metallic band B, the section of which has the form of a reversed U. Upon the
back of the latter are fixed by their centre the springs D D which may vary in
number; each of these springs is fixed, by the end next the shutting post of the
door to a slide E terminated on the same side by an inclined plane b; the other
ends of the springs abut against fixed points d, d, belonging to the cage A.
When the door is open, the elasticity of the springs pushes the slide E outwards
and holds the elastic band in the interior of the cage as shown at Figure 7 so.as
not to interfere with the play of the door; but at the moment of closing, the
inclined plane b comes against a similar inclined plane e fixed to the shutting post
or to other projection or fixture capable of operating the slide E; the slide is then
pushed back, the curvature of the springs increases, and the joint descends outside
its recess to press upon the sill or threshold, as represented at Figure 9. These
various examples show sufficiently how the hygienic joint can be applied in all
cases.
Having thus described the nature of the said Invention and the mode in which
the same is carried into effect I would have it understood that what I claim is :-
The application to all fastenings of dwellings, or of reservoirs, or of receivers
without pressure a joint formed of elastic bands, pressed by springs against the
surfaces to be closed, this pressure being capable of being obtained by the direct
closing of the door or of the cover, or by a special movement acting at the moment
of the closing substantially. as herein shown and described.

In witness whereof I the said Benjamin Joseph Barnard Mills have hereunto
set my hand and seal this Twenty second day of January in the year of our
Lord One thousand eight hundred and eighty four.
