PROVISIONAL SPECIFICATION.
Improved Ventilator for Dwelling Houses and other Buildings
1, JOHN WHIPP of The Elms, Yorkshire Street, Rochdale, in the County of
Lancaster, Dentist, do hereby declare the nature of this invention to be as
followe, that is to say
1
It relates to an improved formation or construction of ventilator for
dwelling-houses and other buildings in which the windows me of the kind
known as sliding sashes, and has for its object the prevention of unnecessary
draughts while the ventilating of the room or building to which it is applied is
effected in a thoroughly efficient manner.
To attain this object I employ a strip, (preferably) of metal (although wood
might be used if desired) which I arrange to extend from one side of the upper
part of the window to the other and on the outside of the building. Through
this strip of metal make a series of slots (or perforations) which I arrange in
groups for the purpose hereinafter explained, and over each of these groups of
slots I place a flexible cover as of leather, cloth or the like (the fabric I find to
auswer the purpose most suitably being oiled silk) in such a manner that it is held
by its upper edge while its lower edge is free.
Over each piece of leather of fabric I place an appropriately formed baffle-
plate or cover so that the pieces of leather or fabric nie thus protected from the
dnect actions of boisterous or inclement weather.
When the ventilator 18 fixed in position and the upper sliding sash is drawn
down a space equal to the breadth of the ventilator or less than this, any heated
air or other gases might freely pass through the slots and out of the room or
building while should a current of air blow in the opposite direction the leather oi
fabuc is forced against the strip of metal and so covers the slots, thus such
curient of air is prevented from entering as it otherwise would do to the detriment
of anyone occupying the 100m.
Further by the upper sash being pulled down as described a gentle current of
air is allowed to ascend being guided by its outer surface to just enter the room
at the top of the window and then escape with the current passing through the
slots.
By these slots being arranged in groups the pieces of leather of fabric are of
smaller dimensions than they would be had one piece to be used to cover the
whole lot, hence they may be moved by a weaken current than would such larger
piece while they fall closer to the strip of metal and more effectually cover the
slots than such larger piece could be made to do
Dated this 18th day of October 1895.

I, JOHN WHIPP of The Elms, Yorkshne Street, Rochdale, in the County of
Lancaster, Deulist do hereby declare the nature of this invention and what
maune the same is to be performed, to be particularly described and ascertained
in and by the following statement, that is to say
It relates to an improved formation ог construction of ventilator for
dwelling-houses and other buildings in which the windows are of the kind
known as sliding-sashes, and lins for its object the prevention of unnecessary
draughts while the ventilating of the room or building to which it is applied is
effected in a thoroughly efficient manner.
In order that my said invention may be more readily understood, I have
hereunto appended sheets of drawings, in which :-
:-
Fig is clevation of a window having my improved ventilator applied thereto,
and as seen from the outside.
Fig 2 is sectional end elevation of parts shewn by Fig. 1
Fig 3 is elevation of parts illustrated by Fig. 1, but as seen in the opposite
direction.
Fig. 4 is a font elevation, enlarged scale, of a portion of my improved
ventilator, and Fig. 5 is sectional end view of same
Fig. 6 is a detail drawing, enlarged scale, hereinafter referred to.
Figs. 7 and 8 are sectional views on lines -, y-y respectively, of said
Fig. 6
To attain the object of my said invention I employ a strip a (preferably) of
metal (although wood might be used if desued) which I arrange at an angle to
the vertical plane as shown by Figs. 2 and 5, to extend from one side of the
upper part of the window to the other 62 and on the outside of sand window, and
in order to be enabled to hx said strip a to slightly different sizes of windows
I form the ends a' so as to slide upon the part a³ of said strip a, as shewn by
Figs. 6 and 8. Through this stip of metal a I make a series of slots (or
perforations) c which I arrange in groups for the purposes hereinafter explained,
and over each of these groups of slots c I place a flexible cover d as of leather,
cloth or the like (the fabric I find to answer the purpose most suitably being
oiled silk) in such a manner that it is held by its upper edge d' while its lower
edge d³ is free.
Over each piece of leather or fabric d 1 place an appropriately formed baffle-
plate or covei e so that the pieces of leather or fabric are thus protected from
the direct actions of boisterous or inclement weather, and, should the said flexible
cover d become wet by any means, in order to prevent it clinging to the strip a
or to the baffle-plate e and thus interfering with the performing of its proper
functions, tmn or bend the edges c' of the metal surrounding the slots c
outwards as shewn by Figs. 6 and 7, and place the grid-like form of metal f
to intervene between sand piece of leather or fabric d and the baffle-plate e.
с
When the ventilator is fixed in position and the upper sliding sash diawn down
a space equal to the breadth of the ventilator or less than this, any heated air or
other gases might freely pass through the slots e and out of the 100m or building,
while should a current of au blow in the opposite duertion the leather or fabric d
is forced against the strip of metal a and so covers the slots e, thus such current
of air is prevented from entering as it otherwise would do to the detrunent of
auyone occupying the 100m
Further by the upper sash being pulled down as described it forms a fresh air
inlet for the 100m which will diect the current of air it admits so as not to
allow it to pass into such part of said room as would cause it to be objectionable.

page_text: By these slots being arranged in groups the pieces of leather or fabric & are
of smaller dimensions than they would be had one piece to be used to cover the
whole lot, hence they may be moved by a weaker current than would such larger-
piece while they fall closer to the strips of metal a and more efficiently cover the-
slots c than such larger piece could be made to do
Although I have described my improved ventilator as being applicable for use
in connection with sliding sashes, I am fully aware that windows specially
constructed with openings at the top but otherwise entirely closed as well as fixed
O stationary may be supplied with them since these would afford ample liberty for
the functions of my umpioved ventilator to be performed.
Having now particularly described and ascertained the nature of my said inven--
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. In a ventilator the combination of the several parts constructed and arranged
substantially as specified.
2 In a ventilator, the combination of a slotted strip of metal, wood or the like,
flexible covers for same and shields for said covers the same being constructed
and arranged as specified.
