New York, United States of America, Manufacturer, whose Post Office address is
Room 52, 140 Nassau Street, New York City, New York, U.S.A. do hereby declare
the nature of this invention to be as follows:
An Improvement in Ventilators for Windows. By an arrangement of two Wheels
formed of segments of glass, of the desired thickness, and so arranged, as to form
alternate spaces.
The segments of Glass to be fixed between a light metal rim and a centre, metal
boss. One Wheel to be a fixture and the other to rotate on a centre pin passing
through both Bosses.
It has, also in addition to the above, two outer metal rings or rims, by which the
Ventilator is secured into the opening cut in Pane of Window glass, or other place
where the Ventilator is to be fixed, by screwing or otherwise clamping the aforesaid
rings securely together. One of the aforesaid rings, to have an inward flange to suit
thickness of Window Pane or other fixture, also to have an internal rim to form a
seating for loose Wheel to work in, and to prevent it coming out of its place.
The other ring to have the stationary Wheel soldered or otherwise fixed to it.
One of the aforesaid rings to be on the outside and the other on inside of Window
Pane, with the loose Wheel working between, and operated by two knobs or Thumb
screws to rotate it on the centre Pin, thereby opening and closing the air spaces, as
desired.
Thin rings of Indiarubber or other soft material are introduced between the metal
rings and the Window Pane, to make the joints water tight, also to prevent the rings
turning, and to strengthen the hole in Window Pane, by giving a more even pressure
and allowing for contraction and expansion between the Ventilator and Window
Pane.

Improvements in Ventilators.
GEORGE RICHARD BUFFHAM, of the City of Brooklyn, County of Kings, State of
New York, United States of America, Manufacturer, whose Post Office address is,
Room 52, 140 Nassau Street, New York City, New York State, U.S.A. do hereby
declare the nature of my invention for AN IMPROVEMENT IN VENTILATORS, and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
My invention is for lessening the cost of manufacture, for allowing different colors
of glass to be used, for strengthening the ventilator itself, and for lessening the risk
of injury to the pane of glass into which the ventilator is inserted..
In the drawings Figure 1 is an elevation of the ventilator complete.
Fig. 2 is a section of the same at the line. Fig. 3 is a seperate view of a part
of one side of the stationary ring. Fig. 4 is a similar view of the moving ring,
and Fig. 5 is a section at the line yy, of Fig. 4.
I make use of two rings, by which the ventilator is secured into the opening cut in
the pane of window glass, or other place where the ventilator is made use of. The
ring A is made with an internal rim, a, and an inward flange b, and the ring B is of a size
to surround the rim a, and there are screws or bolts, by which the rings are clamped
upon opposite sides of the pane of glass or other support, and rings of indiarubber or
other soft material are introduced between the rings A and B and the surfaces of the
glass, to make the joints water tight and to effectually prevent the ring turning.
The ventilator is made of sections of glass with intermediate openings.
These sections may be either cut out or pressed into shape, preferably the latter, and
said sections of glass are ornamented to a greater or less extent, if desired, and it is
preferable to make use of colored glass in one of the wheels and plain or frosted glass
in the other. The sections E. of glass, are connected together at or near the middle,
and at their outer edges they are received into and supported by the rim F, that is of
a size to pass freely into the rim a, and to be turned therein.
This rim F has an inward flange, 2, on one edge to support the outer ends of the
glass sections E, and there are clip pieces 3 applied at each of the outer corners of
the glass sections to hold the said glass sections into the rim F, and to prevent said
sections becoming loose. These clip pieces are preferably seperate from the ring F
and soldered into place; but they may be made as part of the ring, and there is a
thumb piece or knob, 4, upon the rim F, by which the same may be moved to open or
close the ventilator, and the inward flange, b, is removed for a sufficient distance to
allow for the motion of this thumb piece 4, and to form stops in opening and closing
the ventilator. The sections of glass G are received at their outer edges into a rim, 6,
that is of a size to pass into the rim a.
The flange portions 7 of the rim 6; and the clip pieces 8 hold the outer edges of
the glass sections G firmly within the rim 6; and it is now to be understood that in
putting the ventilator together the rim F, with its glass sections E, is to be inserted

page_text: into the internal ring, a, and rest upon inward flange, b. After this the section
of glass G and their rim 6 are to be inserted into place within the internal rim, a,
with the surfaces of glass sections G resting upon the surfaces of the glass sections E.
and the rim 6 is to be soldered into place, or the parts fastned by screws or pins
within the internal rim, u, thereby holding the rim F and the glass sections E in their
proper positions, but allowing them to be turned in opening and closing the ventilator.
In all instances the adjacent surfaces of the glass set directly against each other and
the outer edges are beveled, as shown in figure, 2, to facilitate the securing of the
same into the metal frames.
The mode of construction thus described is available with any desired connection
between the respective glass sections in the middle portions of the respective wheels,
and the central connections can be made of either glass or metal.
I have however represented two Boss pieces, H and K with a central rivet, I, the
respective boss pieces being recessed for the reception of the inner ends of the glass
sections, and these ends of the glass sections are secured into place by plaster of paris
or other cement.
This ventilator may be introduced into an opening in a plate or pane of glass, or it
may be connected with the lead or other frames of casement windows.
Each section of the glass may be surrounded by a metal frame, if desired.
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:
1. A ventilator formed of sections of glass with intermediate openings, and two
frames or rims for supporting such sections and for allowing one frame or rim, with
its sections of glass, to moved upon the other frame or rim, in opening or closing the
ventilator, the adjacent faces of the glass being in contact, and the outer edges of the
sections being beveled where they are secured in the rims, substantially as set forth.
2. The metal ring A, having an internal rim, a, and flange, in combination with
the sections E, of glass, the rim F, for connecting such sections together, the sections G,
of glass, and the rim 6, for connecting such sections together, the rim F being between
the flanges, and the rim 6, and the said rim & being permanently secured within the
rim a substantially as set forth.
3. The combination in a ventilator, of sections of glass E and G, rims for supporting
the same, and the inward flanges and clip pieces for holding the outer ends of the
respective sections of glass within the rims, substantially as set forth.
4. The combination, with a stationary and turning wheel in a ventilator, of the
rings A and B, and the rings of rubber or similar yielding material between the same
and the surface of glass, and the screws for clamping the parts, substantially as
specified.
