Improvements in or relating to "Louvres” or Ventilators.
I, RALPH SHORROCK, of Newhaven, Daiwen, in the County of Lancaster,
Engineer, do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and asoer-
tained in and by the following statement:--
'
This invention refers to improvements in or relating to "louvres" or venti-
lators for admitting atmospheric au-without damp or wet-to provide a vent
to protect cavity walls from damp and decay, and is designed to dispense with
perforated bucks and the like employed hitherto for this purpose. This
louvre or ventilator is constructed of metal or other suitable material or
materials with flat bearing surfaces on each side to allow of the same being
perfectly bedded and fixed flush or otherwise in the wall of a building. Between
the sides of the outer framing are disposed "louvres" of any required number

This
His the "louvie" or ventilator constructed of metal, terra-cotta, sanitary-
ware, and the like, I the "louvies", K walls, and L the cavity The "louvre "
or ventilator H is constructed with the flat bearing surfaces J on the top, bot-
tom, and sides to allow of the same being perfectly bedded and fixed flush or
otherwise with the outside of the wall K Between the top bottom, and sides
forming the flat bearing surfaces J forming the outer framing are disposed
the "louvres" I of any required or desired number placed at any desired angle
to facilitate the efficiency of the same according to the purpose and place to
which it may be applied This invention is designed to dispense with per-
forated bricks and the like, and to admit atmospheric air-without damp or
wet and provide a vent to protect cavity walls from damp and decay
invention is equally applicable for the walls of houses, dwellings, churches,
schools, hotels, farm-buildings, such as stables, shippons, out-houses, and the
like. In adapting this invention to smoky-chimneys the "louvre
or venti-
lator His fixed in the "chimney-stack" M as shown in Fig. 6, which 18 above the
line O, representing the outside of a roof, and the underside of the ordinary
chimney-pot" P By thus placing my improved "louvre or ventilator H
between the upper side of the roof and the underside of the ordinary "chimney-
pot" P an upward current of atmospheric air will be ensured, and in case the
upper end of the "chimney-pot" P 18 located so as to be subject to the action
of wind at periods according to the direction the latter is blowing from a higher
building in close proximity thereto the smoke that is prevented emission from
the upper outlet of the "chimney-pot" P will pass out through the "louvres" I
located in the "chimney-stack" below, thus preventing the same being blown
back to the fire-place or grate from which the smoke 18 generated

Having now particularly described and ascertained the nature of my said
invention and in what manner the same 18 to be performed, I declare that what
I claim is:-
1. The construction and use of the "louvre" or ventilator H consisting of
I
the flat bearing surfaces J, between which are disposed the angular "louvres"
of any required or desired number, composed of either metal, terra-cotta, sani-
tary-ware, and the like for the purposes specified, substantially as described and
as illustrated in the drawing in Figs 1 to 5 inclusive.

lator H consisting of the flat bearing surfaces J, between which are disposed the
angular louvres I of any desired or required number, composed of either
metal, terra-cotta, sanitary-ware, and the like, located or fixed in convenient
