I, HANS FOWLER PRICE, of Tyn y coed, in the Town of Weston super Mare, in the
County of Somerset, Architect and Surveyor, do hereby declare the nature of this
invention to be as follows:-
Instead of the single hopper with its large opening and excessive and unsightly
projection, I propose dividing the opening into two hoppers covered by a single pivot
casement on the outside. By these means the air current is divided into two, and
these have a more upward direction than in the single hopper, thus avoiding
draughts.
The projection of these hoppers is only one half that of the single hopper of equal
area.
These hoppers may be made preferably with glass cheeks cast in solid form, or they
may be made of ware, fixed to the stone or other work, with glass fronts let in, or they
may be made with metal frames as in ordinary hoppers, or of any other suitable
materials.
The pivot casement is opened and closed by means of cords, or wires, and double
pulleys supported by a bracket of iron or other material as shewn.
Fig. 1. is a section, A is the pivot casement, B, B are the hoppers, C is the bracket
with pulleys &c.
Summary of my claim, a ventilating casement having two hoppers dividing the
air current, giving a more upward direction, and lessening the projection of the
hoppers the whole covered by a single pivot casement, the volume of air admitted
being the same as by a single hopper of equal area, all substantially as set forth.

Improvements in Hopper Ventilating Casements.
I, HANS FOWLER PRICE of Tyn-y-coed in the Town of Weston super Mare, in the
County of Somerset, Architect and Surveyor, do hereby declare the nature of this
invention for IMPROVEMENTS IN HOPPER VENTILATING CASEMENTS," and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :—
Instead of the ordinary single hopper with its one casement, large opening and
excessive and unsightly projection, I propose to divide the opening into two parts by
means of a casement horizontally pivoted in the frame, and opening outwardly at the
bottom, and inwardly at the top, and to apply to cach division of such opening a
hopper on the inside, the lower hopper to have two side cheeks and a front sheet, and
the upper hopper to have the two side cheeks with or without the front sheet, but
preferably I apply front sheets to both hoppers.
The projection of these hoppers is only half that of a single hopper of equal
ventilating area, and the air current has a more direct upward tendency.
These hoppers I make preferably with clear glass, both checks and front sheets.
The cheeks cast solid with grooves or rebates to take the front sheets, and fixed to the
stone wood or metal frames of the windows, or the cheeks as before described may be
made of pottery ware, or any other material, or they may form part of the stone wood
or metal frames of the windows, or the hoppers may be made in the ordinary way with
metal or wood frames.
The pivoted casement is opened and closed by a stay bar in the ordinary way. If
out of reach this stay bar is worked by cords wires or chains working on two pulleys
fixed to a projecting metal bracket as shewn. This stay bar may be fixed either at the
top or bottom of the casement frame, but preferably at the bottom.
Fig. 1, is a vertical section. A is the pivot casement. B, B, the two hoppers. C, is
the bracket with pulleys. This bracket is made double and the stay bar works
between the two parts and rests when the casement is open on a cross bar between the
two arms of the bracket to prevent the casement falling against the front sheet of hopper.
Fig. 2. is another vertical section shewing the arrangement with opening stay bar
at the bottom, A being the pivot casement, B, D, the hoppers, and the bracket.
Fig. 3, shews the stay bar as used when within reach, to be worked by hand,
D being a small wedge shaped bolt passing into slots in stay bar to fix the casement
open or closed.
These improved double hoppers may be used separately as above described or in

page_text: combinations of two or more pairs included in one frame, and made to open separately
or together by simultaneous gearing, such combinations being specially applicable to
the windows of hospitals and other buildings requiring a large amount of window
opening space without draughts.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I declare that what I claim is or
A ventilating casement horizontally pivoted, having on the inside two hoppers, one
covering each half of such casement, thus dividing and giving a more upward direction
to the current of air admitted, and lessening the projection of the hoppers inside the
volume of air being the same as that admitted by a single hopper of equal area and
double the projection.
