PROVISIONAL SPECIFICATION.
Improvements in Metallic Sills for Window and Door Frames and
Casings.
We CHARLES CECIL BROAD and CECIL EDWARD MCCANN both of Ivy Mount Cottage
Great Malvern in the County of Worcester Builders, do hereby declare the nature of
this invention to be as follows:--
This invention consists in the substitution of a metallic sill, of such a description as
hereinafter described, for the ordinary oak sill used on sash and other window frames,
and a modification of the same may be applied to door frames.
We will describe the invention as of cast iron although we do not confine ourselves
to any particular metal or mode of production.
The sill is cast of a hollow section with an outline similar to an oak sill, but the ends
of the sill are formed into raised shoes or sockets to receive the ends of the pulley-
styles casings, or side pieces of the window frames so that the point of junction between
the sill and the side pieces instead of exposing a joint, presents a solid metallic face
and prevents the penetration of moisture. At the back of this metallic sill is placed
a wood casing so that the interior view of the frame may present a sill of the same
wood as the rest of the frame, also to form a fixing for window board and linings.
The metallic sill may have ears cast upon it by which to secure it to this casing, a
wood bead being fixed upon the top of the casing will hide these ears. The back
of the metallic sill may be raised to form an additional weathering, the above mentioned
bead being rebated to receive it.
By these means a perfectly weathertight sill will be formed which will be a pro-
tection against the rotting of the ends of the styles or sides of the frame and will ensure
the parts keeping in their true position.
For door frames or casings we form two metallic castings connected together
by a flat sill which may be placed at the floor level or underneath as desired.
By this means the rotting of the ends of the door jambs will be guarded against, and
they will be kept rigidly in their proper position.

Improvements in Metallic Sills for Window and Door Frames and
Casings.
We CHARLES CECIL BROAD, & CECIL EDWARD MCCANN, both of Ivy Mount Cottage
Great Malvern, in the County of Worcester, Builders, 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 & to the letters & figures marked thereon :-
This invention consists in the substitution of a metallic sill (of such a description as
herein-after mentioned) for the ordinary oak sill used in sash and other window frames
& a modification of the same may be applied to door frames.
We will describe the invention as of cast iron although we do not confine ourselves
to any particular metal, or mode of production.

page_text: Referring to the drawings
Figs. 1, 2, & 3, are respectively, a section, elevation, & plan of a sill for a sash
frame.
Figs. 4, 5, & 6, section, elevation, and plan of a sill for a casement frame &
Figs. 7, 8 & 9, section, elevation and plan of a sill for a door frame.
The sill is cast of a hollow section Fig. 1, 4, & 7 with an outline similar to an oak
sill, but the ends of the sill are formed into raised shoes or sockets (a), to receive
the ends (b) of the pulley styles casings or side pieces of the window or door frames
so that the point of junction between the sill & the side pieces instead of exposing a
joint, presents a solid metallic face and prevents the penetration of moisture. At the
back of this metallic sill for sash or casement window frames is placed a wood
casing (c) Fig. 1 & 4) so that the interior view of the frame may present a sill of the
same wood as the rest of the frame also to form a fixing for window board and casing.
The metallic sill may have ears (d) Fig. 3) cast upon it by which to secure it to
the casing, a wood bead (e) (Fig. 1.) being fixed upon the top of the casing will hide
these ears or the back of the metallic sill may be raised to form an additional
weathering as at (f) Fig. 3, the above mentioned bead being rebated to
receive it.
For door frames or casings we form two metallic castings (a). Fige. 7. 8. & 9.
connected together by a flat sill (g) which may or may not have the side pieces (h) and
this sill may be placed above the floor level to form a step, or at the floor level or
underneath as desired.
By these means a perfectly weather tight sill will be formed, which will be a pro-
tection against the rotting of the ends of the styles or sides of the frame and ensure
the parts being kept rigidly in their true positions.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is,
Metallic sills for window and door frames constructed substantially as herein set
forth and illustrated, whereby, instead of the ordinary joint between the sill and
the side pieces or casings, being exposed, a solid metallic face is on the outer
surface.
