PROVISIONAL SPECIFICATION.
Improvements in Fitting Windows, Doors, Show Cases, and other
Articles, and Rendering the same Air and Water-tight.
I, JAMES GEORGE STIDDER, of Petersham Lodge, New Malden, Surrey,
Sanitary Engineer, do hereby declare the nature of my said invention to be as
follows:
:-
The object of my invention is to effect improvements in fitting sliding sashes,
French windows, casements, fanlights, skylights, show-cases, book-cases, jewel-
cases, exhibition-cases, wardrobes, cupboards and analogous articles, whereby the
same are rendered air, dust, and water-tight, and prevented from rattling or jaring.
I fit on the sill of the sliding window or door a metallic channel of U section,
and small drainage pipes or aperatures to carry water therefrom to the outside
of the sill.
I fit a similar (but smaller) channel inside the sash, close to the inside of the
glass, and provide small drainage pipes, to carry away condensed water therefrom
to the first mentioned channel.
To the lower edge of the bottom rail of the door or sash, I fit a metallic bar
of T section; the upper part projecting beyond and over the outer wall of the
first mentioned channel, and the vertical limb of the bar impinging against the
inner edge of the same outer wall of the same channel.
The bottom rail of the door or sash is also fitted with a strip of vulcanised
rubber or other suitably elastic material, which impinges against the inner wall
of the same channel.
I also fit to the upper and lower sash bars and parting rails, strips of vulcanised
rubber fitted into grooves, and projecting sufficiently to impinge against the sills,
transoms, and parting rails, and thereby prevent the entrance of rain and wind, and
rattling of the sashes.
The arrangements above described (with obvious modifications) are also
applicable to doors, French windows, fanlights and skylights.
In fitting French and other casements, doors, show cases, cupboard doors, and
other analogous structures and articles as aforesaid, I fit vulcanised rubber in the
angles, the rubber being preferably formed quadrantal in section, thus forming
an elastic air, dust, and water-tight joint, where the corresponding door frame or
sash enters the angle.
These improvements may be applied to existing doors, sashes, casements and
other structures and articles.

what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-

page_text: And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the recompanying drawings, in which similar
letters of reference indicate corresponding parts.
Fig. 1 is a sectional elevation of my improved wind and water-tight weather bar,
as fitted to the bottom rail of a casement or door.
Fig. 2 is a sectional elevation showing my improvements applied to sliding
sashes.
Fig. 3 is a horizontal section, showing my invention applied to a double door or
casement.
Fig. 4 is a similar section, showing the application of my invention to swing doors.
Fig. 5 is a perspective view, partly in section, showing another method of fitting
doors, for the purpose of excluding draught.
Fig. 6 is an elevation of the same, partly in section.
Fig. 7 and 8 are detail views relating to Figs. 5 and 6.

the sill b. is a drip pipe to carry away the water from the channel a.

plate o, whereby the sliding plate o and rubber g are pressed downwards, when the
door is shut; the rubber being thereby placed in close contact with the floor, so
as to exclude draught. Two or more pins p and cranks may be fitted to the
door to render the motion parallel. When the door is opened the push piece r
and spindle p are pressed outwards by the springs, whereby the crank t, plate o,
and rubber g are raised, the rubber being then clear of the floor. The bottom
of the plate n is curved outwards to throw off' rain, when the door is so situated
as to be subject to the weather.

These improvements may be applied to existing doors, sashes, casements, and
other structures and articles.
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 method of rendering the bottom rails of doors and casements wind and

before described and illustrated by Fig. 1 of the drawings.
2. The application to sliding sashes of rubber tongues fixed in ploughed grooves,
substantially as and for the purposes herein before described and illustrated by
Fig. 2 of the drawings.
3. The application to single or double French casements, windows, doors, show
cases, and other articles requiring the same, of quadrantal strips of rubber,
substantially as and for the purposes herein before described and illustrated by
Fig. 3 of the drawings.
4. The application to swing and single acting doors, of rubber tongues fixed
in ploughed grooves, substantially as and for the purposes herein before described
and illustrated by Fig. 4 of the drawings.
5. The method of fitting automatically acting draught excluders to the lower
parts of doors substantially as herein before described and illustrated by Figs. 5, 6, 7
and 8 of the drawings.
6. The general construction, arrangements and combinations of parts and
appliances, forming my invention of improvements in fitting windows, doors, show
cases and other articles, and rendering the same air and water-tight, substantially
as herein before described and illustrated by the drawings.
