COMPLETE SPECIFICATION.
Improvement in Window Frames and Sashes.
We, THOMAS OSBORNE and WILLIAM WISEMAN, both of 1119 Betz Building,
Broad and City Hall Square, Philadelphia, in the County of Philadelphia, and
State of Pennsylvania, United States of America, Gentlemen, 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 letters of reference.
marked thereon, which form a part of this specification:―
This invention relates to a new and useful improvement in window frames and,
sashes therefor, and has for its object to so arrange these devices as to permit of 1
the ready removal of the sashes from the frame, for the purpose of cleansing, and
when they are so removed, to afford support therefor, in such manner as to
enable a person to gain ready access to the surface of the glass, for cleansing
purposes.
With these ends in view, the invention consists in the details of construction
and combination of elements hereinafter set forth and then specifically designated
by the claims.
Fig. 1, is a central vertical section of a window frame embodying this
improvement;
Fig. 2, an elevation of one side of a window frame, a portion thereof being.
broken away, so as to clearly show the mode of securing the outer retaining
strip;
Fig. 3, a section at the line x, of one side of the window frame, showing the
means employed to secure the inner retaining strip;
Fig. 4, a plan view of the window frame, showing the, supporting brackets.in
position;
Fig. 5, a detail section, showing in enlargement, the arrangement of the spring.
and pin for securing the outer retaining strip; and
Fig. 6, an enlarged view of one of the hooks and staple, by means of which the
inner retaining strip is secured.
Similar numbers denote like parts in the views of the drawing.
1, represents the window frame, and 2, and 3, the upper and lower sashes-
respectively, which are adapted to slide in the usual manner, and may be counter-
balanced by the ordinary weights, which form no part of this invention.
4, is the outside retaining strips, which are usually secured by nails, or, screws
directly to the window frame, for the purpose of affording a guidance for the
inside sash, in its up and down movements. One of these strips is secured in the
manner just described, and the other is provided with headed pins 5, adapted to be
inserted through suitable openings in the escutcheons 6, secured by means of screws
to the inner facing of the window frame. Beneath the openings, of these
escutcheons, the frame is cut away, so as to form a recess, into which the heads of
the pins may be thrust. Secured within the recess of the lower escutcheon, is a
spring 7, so arranged that when the pin 5, is passed through the opening in said
escutcheon, the head of said pin will be engaged by this spring, and prevent its
retraction, except by sufficient pressure being exerted in the opposite direction, to
overcome the tension of said spring. The strip 4, is beveled at its upper end and
adapted to fit with the bevel of the upper strip 8, so that when being placed in its
proper position, its upper beveled end is set between the bevel of the upper strip

page_text: and the inner face of the casing, and when the lower pin is engaged by the
spring 7, it will be seen that the strip will be securely held in place its lower end
matching at 9, with an extension strip 10, or the strip 4, may extend to the bottom
of the window casing and snugly fit against the lower strip 11.
Thus it will be seen that this strip may readily be removed by exerting sufficient
pressure to overcome the tension of the spring 7, and when so removed, the
lower sash 3, may be drawn out of its bearings sidewise, for the purpose
hereinafter set forth.
12, is the inner retaining strip, and is provided with hooks 13, adapted to engage
suitable eyes 14, secured to the casing, within the usual groove in which the strip
sets. By this arrangement, the upper sash may be removed in the same manner
as that just described in connection with the lower sash, by removing the inner
retaining strip, which is accomplished by sliding it upward until its hooks are
disengaged from the eyes.
16, are brackets, having dovetailed ends 17, adapted to engage the dovetailed
grooves of the plates 18, which latter are secured to the face of the window frame,
as clearly shown in Figs. 1, and 4. These brackets are provided with notches 19,
and when it is desired to remove these sashes for cleaning, they are drawn out of
the casing after the removal of the retaining strips, as before described, and hung
by means of their ropes engaging with the notches 19, as clearly shown in Fig. 1,
when one or both of said sashes are readily accessible, in order that the glass
contained therein may be thoroughly cleaned.
When the sashes have been replaced, the brackets 16, may be removed from the
plates by forcing their dovetailed ends upward, out of the corresponding grooves
in the plate, and these brackets may be then laid away for further use.
Thus it will be seen that a very convenient means is provided for manipulation
of the sashes, in order to clean the same without the necessity of the operator
having to lean out of the window, as has heretofore been the case, and therefore
attendant with considerable risk and inconvenience.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. A window frame having removable strips secured therein, by means of
which the sashes may be withdrawn, in combination with notched brackets adapted
to be temporarily secured to the face of said frame, for the purpose of supporting
said sashes, as shown and described.
2. In combination with a window frame and the sliding sashes thereof, the
strips 4, and 12, adapted to be removed, whereby said sashes may be withdrawn
temporarily from their bearings, plates secured to the face of the window frame,
having dovetailed grooves therein, and notched brackets having dovetailed ends
adapted to fit said grooves, whereby the sashes may be supported within the room
when withdrawn from their bearings, as shown and specified.
Dated this 14th day of September 1896.
