Improvements in Metal Window Frames and Sashes.
I, CHARLES ALBERT HASLETT, of 417, Locust Street, Philadelphia, Pa., U.S.A.,
President of the Bertolett Manufacturing Company, do hereby declare the nature
of this invention to be as follows:-
This invention relates to improvements in metal window frames and sashes;
the object of the invention being to provide a durable fireproof window of simple
and neat construction.
By this invention, the window sill is covered with sheet metal upon which
tubular pillars rest and are retained in place by being clamped between the sill
and the metal upper portion of the window frame by means of a rod extending
through each pillar and having its ends screw-threaded and fitted with nuts.
Tubular pillars are arranged on each side of those aforementioned and form
enclosures for the sash weights which are suspended therein by strands, preferably
wire passing over pulleys supported by the upper part of the frame, and connected
to the sashes.
The enclosures for the weights are conveniently secured in place by having
their lower ends resting over a disc secured to the sill, and their upper ends
entering into and through the upper part of the window frame. By this means
they can be raised from off the discs and readily removed when it becomes neces-
sary to have access to the weights or strands.
The sashes are made up of hollow metal top, bottom, and side pieces of suitable
section such as hexagonal or pentagonal, and bolted to suitable corner pieces of
similar section. A groove in the side pieces, top and bottom pieces, and corner
pieces serves to retain glass or other substance or material, fireproof or otherwise.
The sashes are provided at their sides with flanges of suitable shape to slide
between the pillars first mentioned and the weight enclosures respectively.
The window frames are conveniently held in position by means of metal V or
other suitably shaped projections on the walls.
The upper bar of the lower sash, and the lower bar of the top sash are shaped
in such manner that they fit closely together.

page_text: 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:-
My invention has relation to a fire and water proof polygonal form or tubular
metal window frame and sash, and in such connection it relates to the general
construction and arrangement of the same.
The principal objects of my invention are, first, to provide a comparatively
inexpensive; durable, and efficient fire and water proof metal framework for
windows as well as the sash thereof, the metal work of the same being of tubular
or polygonal form or shape, and, second, to provide a tubular or polygonal metal
framework for windows and the sash thereof so arranged that the parts or members
of the same can be readily assembled, and when necessary taken apart, and a
window frame and sash that is fire and water proof, substantial or solid and the
use affording greater protection to the structure into which applied, and adapted
to be made ornamental and the sash made practically air and water tight.
My invention stated in general terms consists of a metal window frame and
sash therefor when constructed and arranged substantially in the manner herein-
after described and claimed.
The nature and scope of my invention will be more fully understood from the
following description taken in connection with the accompanying drawings, form-
ing part thereof, in which—
Figure 1 is a perspective view of a metal window frame and sash embodying
characteristic features of my present invention a portion of the metal framework
being broken away to expose to view inner portions of the same, as well as the
sash thereof. Fig. 2 is a vertical central sectional view of the window framework,
partly broken away in order to illustrate the metal window-sash and also a
preferred shape of head and sill of the window framework. Fig. 3 is a transverse
sectional view on the line - of Fig. 2, showing a portion of the metal frame-
work and sash, weight boxes or tubes, and tubular supports, to which are suitably
attached the head of the framework and the sill thereof. Fig. 4 is a vertical
sectional view of the lower part of the metal framework of the window on the
line y-y of Fig. 2. Fig. 5 is a plan view in broken section, of a portion of the
tubular metal sash. Figs. G and are respectively front and side elevational
views of the corner unions for the respective tubular metal sash. Fig. 8 is a top
plan view of the pulleys over which the cords connected with weights are adapted
to travel in the boxes or tubes of the framework of Figs. 1 and 2; and Fig. 9 is
a cross sectional view, enlarged, in detail of the lower window sash and runner
at the left hand side of Fig. 1, illustrating the pivotal connection between the
sash and runner.
Referring to the drawings, A represents the metal framework of the window in
tubular or polygonal form, as clearly illustrated in Figure 1.
a is a metal head, and the metal sill, of the framework.
and are vertical metal tubes on each side, engaging respectively, the
head and sill for holding the same required distances apart. These tubes a²
and are threaded at their upper and lower ends and are provided with threaded
bushes screwed into the upper and lower ends of said tubes a² and a³ so as to
project therefrom and adapted to pass through openings 10, provided therefor in
the metal head and sill a¹ of the framework A, and the said bushes have
applied to their projecting ends threaded collars or the like a for securely holding
said head and sill to position, illustrated in Figs. 1 and 4.
and are metal weight tubes inserted through the head a and sill a² of the
framework, as clearly illustrated in Figs. 1, 2 and 3 of the drawings. These
tubes b and 1 at their lower ends are provided with lugs or projections 2 and 3,
resting upon the window sill and holding thereby the said tubes in operative
position. These lugs or projections 12 and 3 are prevented from entering the
openings and 5, provided in the window sill a¹, by holts and 67, secured
in any preferred manner into the sill a', as clearly illustrated in Fig. 3. The

page_text: weight tubes b and b¹ may be readily removed from the head and sill by suffi-
ciently raising the same to cause the lugs or projections 63 and 63 to be brought
beyond the bolts and bi and above the openings and 6 through which open-
ings the lugs or projections may be withdrawn to disengage the upper ends of
said tubes from the head a. The lower ends may be withdrawn from their engage-
ment in the sill by raising the tubes and and passing the lugs or projections 2
and 3 of the same through the openings band. This withdrawal or release of
the tubes and will only be resorted to in the event of the sash-weight cord
being broken, affording thereby a ready as well as a quick means for replacing
the same.
68 and 9 are pulleys journalled to a bridge piece 610, supported on the head a
as clearly illustrated in Figs. 1 and 2. Over each of the said pulleys passes a
cord, chain or wire 61. connected at one end with weights (not shown) adapted
to be mounted in the respective tubes band and at the other end connected
with T-shaped runners e and e', provided with concave-shaped faces having arched
springs with which the sash-frames D and D' engage, as will be presently more
fully explained. The rear shanks of the T-shaped runners cand e rest between
the stationary supporting tubes or cylinders for the head and sill and one of
the weight tubes bor to form thereby a good bearing surface in the sliding
movements of said runners c and c¹.
The concave faces of the runners e and c¹ on each side of the framework A are
provided with concave shaped springs and 3 with which the tubular metal
sides of the respective sash engage, as shewn in Figs. 1 and 9, in order to form
a tight connection between the said runners and the sash.
The upper and lower sashes 1) and Dare composed of preferably double top,
bottom, and side metal tubes d, d', d², and, and at the respective ends are
joined to double elbows +, provided, respectively with sleeves entering and
suitably secured into said tubes as clearly illustrated in Figs. 6 and 7. The
double tubular sashes D and D₁ have the glass inserted between the tubes con-
stituting the sash in a body or mass of rubber, cement, putty, or other preferred
material. The respective upper and lower sashes D and I are connected with
the runners and by means of pivots e and e' on the respective sides passing
through the inner tubing of the upper sash D, and through the outer tubing
of the lower sash D', as clearly illustrated in Fig. 1 of the drawings. The
pivoting or supporting of the sashes D and D in the above manner within the
framework and to the slidable runners and enables the sashes when brought.
into their respective operative positions to establish a good binding surface
between meeting parts of both members of the said sash. Moreover it may be
remarked that by pivotally supporting the sash as explained the same may be
freely turned for cleaning both sides of the glass therein, as well as affording
greater ventilation of a room provided with such a framework and sash.
At the top or head a of the framework A is provided a U-shaped trough f,
into which the double tubular members of the sashes D and D' are adapted to
enter or seat in order to ensure a tight joint thereabout or prevent passage of
air between the sash and head a. The interior of the trough f may be provided
with a packing of rubber or other vielding material, so as to form a cushion, and
thereby an absolutely air-tight connection of the upper end of the sash D with
the head of said window frame A. The sill a is so constructed and arranged
that a seat for the lower portion of the sash D¹ is provided to ensure an air and
water tight connection of the same with the said sill a¹, as will be readily under-
stood from Figs. 1 and 2 of the drawings.
It will be manifestly obvious that the framework and sash may be made polv-
gonal in form. instead of being tubular as shown in the drawings, and equally
good results will be obtained in the assembling and use of the parts, and hence
I do not wish to be understood as limiting myself to the precise construction and
arrangement of all the parts of my said invention, as hereinbefore described and
illustrated.
