1, ELOI JOSEPH DIVE, of Epperville (Somme) France, Oil Manufacturer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to apparatus for admitting air to apartments, sleeping
chambers, or the like.
The improved apparatus can be easily actuated by means of a cord which can if
necessary be arranged to operate without leaving the seat or bed.
The said apparatus is essentially composed either of two plates capable of sliding
one upon the other so as to uncover a greater or less number of orifices formed in the
uprights of the window against which the apparatus is applied, or of a panel provided
with a certain number of holes which can be uncovered at will by means of a plate
actuated by a cord, the said panel being placed at any point to establish communication
with the external air, for example, in the corner of a window. In the latter case one
of the panes is cut out of the window to enable the panel to be inserted.
In order to render the operation of my apparatus very efficacious, it is desirable
that the holes which convey the air from the outside are placed in an oblique
direction, so that the air on entering the apartment, rises to the ceiling, in this
manner the said air is heated slightly before spreading in the apartment.
An agreeable ventilation is thus effected, which has not the defects of a direct
horizontal admission of the air from outside; especially in cold weather.
Upon the frame of the window pierced with a number of oblique holes, is fastened
a metallic plate having dove-tail guides and likewiso provided with a number of
oblique holes corresponding to the holes in the window frame. On this guide plate
moves a metallic regulating plate, which according to its more or less elevated
position uncovers a greater or less number of holes.
A small transverse plate is fixed to the upper part of the guide plate and serves as
an abutment for the regulating plate. This regulating plate carries a knob to which
is attached one end of the cord which serves to actuate the plate. This cord passes
over a pulley and carries at its other extremity a certain number of knots corresponding

page_text: to the number of holes in the guide plate and which serve to stop the regulating
plate at the proper point by attaching one of these knots to a fixed hook screwed
upon the window frame.
When more or less of the openings are to be uncovered, the regulating plate is
lowered under the action of its weight, and is stopped by means of one of the knots
with which the cord is provided engaging with the hook.
In order to ensure that the air which passes through the openings shall pass
upwardly in an oblique direction a piece of wood provided with oblique holes
corresponding to those previously described is secured upon the window frame. This
arrangement has the effect of forming conduits of a certain length, which ensures the
proper direction of the air current.
According to a modification of the preceding arrangement, two cords are used,
these being attached to the extremities of a cross bar fixed to the upper part of the
regulating plate.
This arrangement has for its object to prevent the current of air which passes
through the holes being broken, the cords being placed one on each side of the line
of openings.
One cord passes over a pulley having a simple groove, then through one of the
grooves of a double pulley, through the other groove of which passes the second
cord. The cords are moreover united at their free extremities so as to have only a
single operation to perform to cause the regulating plate to slide.
When a panel is applied to a window it has upon two adjacent sides two rims
which serve to fix it upon one of the uprights and the upper transverse piece of the
window.
The pane is cut according to the form of the panel, the latter being fixed upon the
frame as described. The pane is puttied on the other sides of the panel.
At the rear of the panel are fixed two ribs which serve as guides for the regulating
plate which can descend under the action of its weight when the cord fixed to it is
relaxed. It is this plato which according to its position produces the opening or
closing of one or more lines of holes.
The operating cord can pass over guide pulleys, in order that the admission of air
can be effected from any desired seat or from a bed.
Two projections fitted upon the regulating plate stop this latter in the lowest
position by abutting against two tappets fixed upon the guides. A metallic strip
screwed upon the panel stops the regulating plate in its upper position.

page_text: I, ELOI JOSEPH DIVE, of Epperville (Somme) France, Oil Manufacturer 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:
This invention relates to apparatus for admitting air to apartments, sleeping
chambers, or the like.
The improved apparatus can be easily actuated by means of a cord, which can if
necessary be arranged to be operated without leaving the seat or bed.
The said apparatus is essentially composed either of two plates capable of sliding
one upon the other so as to uncover a greater or less number of orifices formed in the
uprights of the window against which the apparatus is applied; or of a panel provided
with a certain number of holes which can be uncovered at will by means of a plate
actuated by a cord, the said panel being placed at any point to establish communication
with the external air, for example in the corner of a window. In the latter case one
of the panes is cut out of the window to enable the panel to be inserted.
In order to render the operation of my apparatus very efficacious, it is desirable
that the holes which convey the air from the outside are placed in an oblique
direction so that the air on entering the apartment rises to the ceiling; in this
manner the said air is heated slightly before spreading in the apartment.
An agreeable ventilation is thus effected which has not the defects of a direct
horizontal admission of the air from outside, especially in cold weather.
The accompanying drawings represent various arrangements of my improved
ventilating apparatus.
Referring to Figures 1 to 4 upon the frame A of the window, provided with a
number of oblique holes o is fastened a metal plate a having dovetail guides and
likewise provided with a number of oblique holes corresponding to the holes o in the
window frame. On this guide plate moves a metal regulating plate B which according
to its more or less elevated position uncovers a greater or less number of holes.
A small transverse plate b is fixed to the upper part of the guide plate a and serves
as an abutment for the regulating plate B. This regulating plate carries a knob c to
which is attached one end of the cord d which serves to actuate the plate. This cord
passes over a pulley e and carries at its other extremity a certain number of knots,
corresponding to the number of holes in the guide plate and which serve to stop the
regulating plate at the proper point, by attaching one of these knots to a fixed
hook screwed upon the window frame.
When more or less of the openings o are to be uncovered, the regulating plate B is
lowered under the action of its weight, and is stopped by means of one of the knots
with which the cord d is provided engaging with the hook.
In order to ensure that the air which passes through the openings shall pass
upwardly in an oblique direction a piece of wood c provided with oblique holes
corresponding to those previously described is secured upon the window frame. This

page_text: arrangement has the effect of forming conduits of a certain length, which ensures the
proper direction of the air current.
According to the modification represented in Figure 5 two cords
are used
which are attached to the extremities of a cross bar 9 fixed to the upper part of the
regulating plate B.
This arrangement has for its object to prevent the current of air which passes
through the holes o being broken, the cords h, h' being placed one on each side of
the line of openings.
h
One cord ½ passes over a pulley having a simple groove & then through one of the
grooves of a double pulley ¹ through the other groove of which passes the second
cord h. The cords h h' are moreover united at their free extremities so as to have
only a single operation to perform to cause the regulating plato B to slide.
Figure 6 illustrates on a small scale the application of the improved apparatus
described in Figures 1 to 4.
In the modification of my invention illustrated in Figures 7 to 11 in which a panel D
is applied to a window the said panel is provided upon two adjacent sides with
rims m n which serve to fix it upon one of the uprights and the upper transverse piece
of the window.
The pane is cut according to the form of the panel, the latter being fixed upon the
frame as described. The pane is puttied on the other sides p, q of the panel D.
At the rear of the panel D are fixed two ribs rr which serve as guides for the
regulating plate g which can descend under the action of its weight when the cord s
fixed to it is released. It is this plate which according to its position produces the
opening or closing of one or more lines of holes 1.
The operating cords can pass over guide pulleys, in order that the admission of air
can be effected from any desired seat or from a bed.
Two projections & t fitted upon the regulating plate G, stop this latter in its lowest
position by abutting against two tappets vv fixed upon the guides r r. A metal
strip screwed upon the panel D stops the regulating plate in its upper position.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
1 claim is.
An improved apparatus for admitting air to apartinents bed chambers, and the like,
consisting either of a piece of wood provided with a single line of holes, or of a panel
provided with several holes formed obliquely so as to direct the current of air towards
the ceiling of the apartment to be aired, and any number of which holes may be
closed by a regulating plate sliding between guides, and which can be lowered under
the action of its weight by releasing one end of a cord the other end of which is
attached to the sail plate and by again securing the cord so as to maintain the
regulating plate in the desired position as above described.
Dated this 5th day of October 1887.
