Improvements in Ventilators for Windows, Sashes, and Doors.
I, GEORGE RICHARD BUFFHAM, of Portchester, in the State of New York, United
States of America, Manufacturer, do hereby declare the nature of this invention to
be as follows:-
In carrying out my invention I make use of a fixed ring set into a frame of glass,
or into a metal frame holding various coloured or art glasses, and within this fixed
ring is a stationary frame holding glasses that form one portion or disc of the
ventilator, the other portion or disc of the ventilator, which is movable, is composed
of a series of glasses set into a frame with diamond-shaped openings between the
glasses, and the movable portion can be turned so that its glasses coincide with the
glasses of the fixed frame and thereby open the ventilator, or it can be turned so
that the glasses of the movable frame cover the diamond-shaped openings in the
fixed frame thereby closing the ventilator.
The metallic frames receiving the glasses of the ventilator are stamped out of sheet
metal, and there are preferably ten of these frames, five for the stationary portion of
the ventilator and five for the movable portion.
Each frame for the stationary portion is made with an outer circular portion to
be soldered to the fixed ring before mentioned, and with an inner circular portion
to be connected to the ring or bezel of the ventilator, and from this inner
circular portion the frame extends as two radial arms, the outer portions of
which are bent to flare outwardly and join the outer circular portion of the
frame.
The frames of the movable portion of the ventilator are exactly the same shape as
those of the stationary portion of the ventilator, and each frame in section is
L shaped so as to receive the glass, and there are points at intervals upon the flanges
of the frame that can be turned over to confine the glass in place.
The bezel to which the inner ends of the frames of the stationary portion of the
ventilator are connected is a short cylinder occupying the centre of the ventilator
and upon which the movable portion of the ventilator turns: there is a ring loose
upon this bezel to which the inner ends of the frames of the movable portion of
the ventilator are secured by solder, and this ring is kept in place by a returned
flange made upon one end of said bezel the adjacent portions of the outer
ends of the frames of the movable part of the ventilator are connected by solder, or
otherwise.
I prefer to secure the inner ends of the frames of the stationary portion of the
ventilator to a second ring that is secured to the bezel as next explained, and the
loose ring before mentioned is between said second ring and the returned flange upon
the bezel.
Said second ring is made with an inward flange having notches therein and
upon the end of the bezel opposite to the flanged end there are tongues that
pass through the notches of the flange and said tongues are turned over and
securely hold said second ring and the stationary frame in place upon the
bezel.
- An ornamental ring may be applied to cover the tongues and notched flange.
A glass may be placed within the bezel and held by the flanges before mentioned.
I provide stops upon the flange of the fixed ring of the ventilator which limit the
movable portion of the ventilator by knobs upon the latter coming into contact with
said stops. Said knobs may be acted upon by hand, or by cords hanging from said
knobs.

Improvements in Ventilators for Windows, Sashes, and Doors.
I, GEORGE RICHARD BUFFHAM, of Portchester, in the State of New York, United
States of America, 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, reference being had to the accompanying
drawings and to the letters and figures marked thereon, that is to say :-
In carrying out my Invention I make use of a fixed ring set into the glass or the
frame-work holding various colored glasses, and within this fixed ring is a stationary
frame holding glasses that form one portion or disc of the ventilator. The other
portion or disc of the ventilator, which is movable, is composed of a series of frames
containing glasses with intermediate openings, which can be turned in such a manner
as to coincide with the glasses in the fixed frame and thereby open the ventilator, or it
can be turned so that the glasses in the movable frame cover the openings between
the glasses and the fixed frames, and thereby close the ventilator, and the central
portion of the ventilator is a circular ring or bezel holding a glass. By this improve-
inent the construction of the ventilator is simplified and rendered highly ornamental,
and the parts composing the frames are easily set together, and the glasses
can be moulded so as to be of a uniform size and shape to set into the respective
frames.
In the drawings, Fig. 1 is an elevation of the ventilator complete: Fig. 2 is a
section, in larger size, through one side of the ventilator at about the line of
Fig. 1 and Fig. 3 shows one of the metal frames for holding the glass of the
ventilator, and the centre bezel is also shown in this figure.
The fixed ring A is of metal, and it is secured within an opening in the glass or
window to be ventilated. Where the window is composed of art glass" of different
colors set into metal strips or frames, the fixed ring A will be secured to the circular
frame B of the art glass, as represented in the drawings.
The metallic frames receiving the glasses of the ventilator are each made as illus-
trated in Fig. 3. Each frame is, by preference, stamped out of a metallic sheet, with
the outer edges bent up to form flanges 1, which are provided at intervals with
projecting points 2, that are bent over upon the surface of the glass for holding the
same in position. Each glass D is of a shape to fit into the frame C and it is
preferably cast into a mould, so as to be recessed on the surface near the edges, in
order that the surface of the glass and the frame may be level. These frames C do
not extend to the centre of the ventilator, but they surround a short cylinder or
_central bezel E, and the sides of the frame C occupy radial positions from the centre
of the bezel E and then flare outwardly-to the arc, forming the outer part of each
frame. The frames which are represented are of a size to occupy one-fifth of the
circumference of the ventilator, and in making up the ventilator ten of these frames
are made use of, five of them being attached permanently at their edges to the fixed
ring A, and five of them being connected together at the ends of the arcs and to
a central ring 4 around the bezel E, so as to form the movable circle or disc of the
ventilator.
In constructing this ventilator it is preferable to make a centre bezel E with a
returned flange 5, to form an edge that retains the ring 4, and there is a second
ring 6 around the central bezel E, to which the inner ends of the frames Care firmly
soldered, and this ring 6 should have an inwardly turned and notched flange 9, and
upon the edge of the central bezel E there are spurs 7, that pass into the notches in
the flange 9 of the ring 6.
In putting the parts of this ventilator together it is preferable to insert the glasses
into the respective frames C and bend over the points 2, or sufficient of them, for
holding the glasses D in the respective frames, and the frames C that form a movable
portion of the ventilator, are attached to the ring 4, and also the angles of the
frames C at the ends of the curved arcs are soldered, or otherwise fastened, together.

page_text: The circle or disc composed of these frames set together is now placed within the
fixed ring A and it lies against the inward flange 8 of the fixed ring A. The similar
disc or circle of frames and glasses soldered together at the ends of the arcs and at
the central portions to the ring 6 is now laid upon the circle of frames and glasses
before described, and within the fixed ring A and the central bezel E is passed through
the ring 4, and also through the ring 6, and the spurs 7 pass into the notches of the
inwardly turned flange 9 of the ring 6, after which these spurs 7 are to be turned
over outwardly to hold the ring 6 permanently upon the central bezel E, and the outer
edges of the frames C are to be permanently fastened into the fixed ring A by solder
or otherwise. The central bezel E can be left open if constant ventilation is desired
to the extent of this opening; otherwise a circular glass G is to be introduced into
this central bezel E before the ring 6 is attached thereto. Thereby the central glass G
is retained between the returned flange 5 and the flange 9 of the ring 6. The
movable disc or ring of the ventilator may be partially rotated upon or against the
fixed portion of the ventilator by hand, or by cords or wires. For this purpose
I prefer to make use of knobs H, I, at opposite sides of the movable portion of
the ventilator, which may be acted upon by hand, or by cords or wires hanging from
the same.
By the peculiar construction of the frames C the glasses are held very firmly in
position, and there are diamond-shaped openings in both the fixed and movable por-
tions or discs of the ventilator between the respective glasses, and these diamond-
shaped openings in the moveable disc of the ventilator can be made to coincide with
the similarly shaped openings in the stationary disc of the ventilator, thereby opening
such ventilator, or the movable disc of the ventilator can be turned to partially or
entirely close such openings, and the ventilator is highly ornainented and the radial
bars of the frames Ccoincide when the ventilator is either entirely open or entirely
closed.
Thereby such frames obstruct the light but little, and the ventilator closes very
tightly, because the radial portions of the frames C coincide and the tapering or
diamond-shaped portions of the frames at the openings rest upon the surfaces of the
respective glasses in the opposite disc of the ventilator; and in order to render the
ventilator ornamental to correspond with the art glasses surrounding the same,
the glasses set in the separate frames may vary in color, as desired, and these
glasses, together with the central circular glass, may be transparent, ground, or
opalescent.
Upon the flange 8 stops 10 should be fastened at the proper points to limit the
movement of the movable disc of tho ventilator by the knobs H, I, coming in contact
with the same, so that the moveable disc of the ventilator can only be turned a proper
distance either to open or close said ventilator.
It is to be understood that the respective frames can be soldered to the ring 4,
and at the ends of the arc portions of the frames, before the glasses are put in, if
desired, and the same mode of procedure may be followed in connection with the
frames C that are soldered to the ring 6 and, if desired, an ornamental metal
ring 12 may be applied to cover up the spurs 7 and notched flange 9 and render the
ventilator more ornamental at this side thereof.
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. The sheet metal frames C, having projecting points, in combination with the
glasses inserted into such frames and secured by the points that are turned over the
edges of the same, and the surrounding and open central rings to which such frames
are connected for forming the stationary and moveable discs of the ventilator,
substantially as set forth.
2. The metal frames C and the respective glasses within the same, in combination
with the rings 4 and 6, to which the respective frames C are fastened to form

page_text: the ventilator discs, the fixed flanged ring A, within which the two discs are
received, and a central glass within the rings, substantially as set forth.
3. The central bezel E. having a returned flange 5 and spurs 7, in combination
with the ring 6, secured by the said spurs, and the movable ring 4, surrounding
the central bezel, the glasses and the frames C, attached to the rings 4 and 6,
respectively, and forming the ventilating discs, and the fixed flanged ring, A, within
which the ventilator discs are received substantially as set forth.
.
4. The combination, with the ventilator discs having glasses and metal frames
carrying the glasses, of the fixed flange ring A, within which the ventilator
discs are received, the art glasses surrounding such ventilator, and the metal
frames attached to the fixed ring A and receiving the art glasses, substantially as set
forth.
