IMPROVEMENTS IN THE CONSTRUCTION OF WINDOW-SASH AND DOOR FRAMES."
Year: 1882

page_text: LETTERS PATENT to Joseph Hoffe Miles, of Southampton, in the County of
Hants, for an Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF
WINDOW-SASH AND DOOR FRAMES."
PROVISIONAL SPECIFICATION left by the said Joseph Hoffe Miles at the
Office of the Commissioners of Patents on the 8th February 1882.
JOSEPH HOFFE MILES of Southampton in the County of Hants.
MENTS IN THE CONSTRUCTION OF WINDOW-SASH AND DOOR FRAMES."
" IMPROVE-
This Invention has for its object improvements in the construction of window-
sash and door frames and consists in making them in separate parts of cast or
wrought metal so that the parts can be readily put together united fixed and
built up in their places as the building progresses or they may be let into and
fixed in suitable openings left in the walls of a building arranged to receive
them. By this means window-sash and door frames are greatly reduced in
cost and much time and labour is saved in fitting and fixing the same.
In carrying out my improvements I construct a window-sash frame (or it may
be a door frame) in several separate parts to form the sides top and bottom of
each frame. The ends of these separate parts are so formed with lugs projections
slots or holes as to fit or dovetail together being readily secured by keys pins or
otherwise.
Each part is formed with a rib or ribs at the back to impart strength thereto
and to afford security to them when fixed in their places.
In some cases I form such frames from bars of wrought iron of Tangle trough
or other suitable section the parts which form the dovetails or joints being cast on
to the ends of such bars in like manner to the bars which form the side and end
rails of metal bedsteads.
Or the ends of the bars may be formed with joints to fit together.

Josepn Horfe MILES of Southampton in the County of Hants. IMPROVE-
MENTS IN THE CONSTRUCTION OF WINDOW SASH AND DOOR FRAMES."
This Invention has for its object improvements in the construction of window
sash and door frames and consists in making them in separate parts of cast or
wrought metal so that the parts can be readily put together united fixed and built
up in their places as the building progresses or they may be let into and fixed in
suitable openings left in the walls of a building arranged to receive them. By this
incans window sash and door frames are greatly reduced in cost and much time and
labour is saved in fitting and fixing the same.
In carrying out my improvements I construct a window sash frame (or it may
be a door frame) in several separato parts to form the sides top and bottom of
each frame. The ends of these separate parts are so formed with lugs projections 1
slots or holes as to fit or dovetail together being rendily secured by koys pins or
otherwise.
Each part is formed with a rib or ribs at the back to impart strength thereto
and to afford security to them when fixed in their places.
In some cases I form such frames from bars of wrought iron of Tangle trough a
or other suitable section the parts which form the dovetails or joints being cast on
to the ends of such bars in like manner to the bars which form the side and end
rails of metal bedsteads.
Or the ends of the bars may be formed with joints to fit together.
In constructing my improved metal sash frame in cast metal I make them in
four or more parts having a rib or ribs cast on the outside to strengthen them and
also to form a tie in the brick-work.
When it is desired to construct an ordinary sash frame with weights and pullies
I cast on the inner side of the two uprights a small rib and on the top end
immediately below the fork two boxes to carry the sheaves for sash lines. Screw
holes are cast along the edges for screwing the outer bead and moulding to. The
ends of the two uprights have a piece cast out forming a fork or it may be a
square hole or mortico into which fits a corresponding solid piece or tennon which
is cast on the cross bars. This tennon has a cotter hole east in to receive a cotter
for holding the four parts together.
When it is desired to construct these metal frames for swinging sashes either on
the ordinary plan or by any of the improved methods the sheave boxes and sinall
inner rib are not cast on but suitable bosses with holes to take the bearing pins
are provided.
And in order that my improvements may be clearly understood and readily
carried into practice I will proceed to describe the Drawings hereto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation showing the mode of connecting the parts of my
improved metal sash frame together.
a is tho side frame, the cross bar, c is the box containing the sheave. On the
ends of the frame a joggles projections or bosses & are cast against which the
cotter bears. The solid part or tennon e beds on the top e at one end and on the
other end suitable joggles or bosses aro cast which form a bed or bearing so that

page_text: when the parts are put together and the cotters driven home they are pulled up
square and held as firm as though cast in one piece.
Figure 2 is a side view of the upright frame a and Figure 3 a plan of the cross
bar b, c are the sheave boxes for the cord pullies. d, d, the joggles or bosses.
ff the ribs, e the solid tennon with the cotter hole g.
In constructing my improved frames of wrought metal I sometimes use Ţ or
angle iron and cast on the ends similar parts to those shown in Figure 1 or Ioll
light metal plate in the form of a channel and set the ends at an angle of 45° to
form a mitre these ends being placed together and held by a bolt or other suitable
mechanical contrivance.
Having thus described the nature of my Invention and the manner of performing
or carrying the same into practice I would have it understood that I make no
claim to any of the parts separately which are well known and in common use nor
to the construction of window sash and door frames of metal, but what I
claim is
The improved construction of window sash and door frames in separate parts of
cast or wrought metal so that they can be readily combined and secured together
substantially in the manner and for the purpose herein before described and
represented in the Drawings hereto annexed.
In witness whereof I the said Joseph Hoffe Miles have hereunto set my hand
and seal this Fifth day of August in the year of our Lord One thousand
eight hundred and eighty two.
