Self-acting Draught Preventer.
I JOSEPH WILSON of No. 7 Weston Terrace, Weston Road, Strood in the
County of Kent, Storekeeper, do hereby declare the nature of this invention to be
as follows:-
The invention is a "draught preventer," to be fixed to a door, and consists of a
board the full length of the door, grooved at the bottom inside edge and faced with
baize. A baize pad, stuffed with wadding, fills up the groove. A wrought iron
rod is fitted into a bracket in the board which is supported by a bracket with two
lugs. Between the two lugs is a coil spring and a nut and washer. The rod is
connected with a two-armed lever (which hangs in a bracket), by a rod with a
socket at each end. The top arm of the lever is connected with another rod by
means of a steel wire rod fitted with a knuckle at one end and an arm at the other.
The rod is supported by a bearing. The rod is fitted to a lever which swings in a
bracket and projects beyond the edge of the door. A bracket is embedded flush
with the door post. When the door closes, the lever strikes the door post bracket
and imparts a movement to all the other fittings, thereby forcing the board tight
on to the floor. When the door opens, the coil spring sends the fittings into their
previous positions, thus lifting the board clear of the floor.

I, JOSEPH WILSON of No. 7, Weston Terrace, Weston Road, Strood, in the
County of Kent, Engineer 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 :—
This invention relates to a self acting draught preventer to be fixed to a door,
and consists of a board to be made the full length of the door, grooved at the
bottom inside edge, and faced with baize or other suitable material. A pad of
baize or other suitable material fills up the groove. A wrought iron rod is fitted
into a bracket in the board which is supported by a bracket with two lugs.
Between the two lugs is a coil spring and a nut and washer. The rod is connected
with a two armed lever, which hangs to a bracket by a rod with a socket at each
end. The top arm of the lever is connected with another rod by means of a steel
wire rod fitted with a knuckle at one end and an arm at the other. The rod is
fitted to a lever which swings in a bracket and projects beyond the edge of the
door. Another bracket is embedded flush with the door post. When the door
closes, the lever strikes the door post bracket, and imparts a movement to all the
other fittings, thereby forcing the board tight to the floor. When the door opens
the coil spring sends the fittings into their previous positions thereby lifting the
board clear of the floor.

page_text: To enable my invention to be clearly understood, I will now more particularly
describe the same by the aid of the accompanying drawings
Fig. 1. is a complete drawing of the apparatus.
:-
Fig. 2. is a side and sectional view of that part of the apparatus corresponding
with the letters, E. F. H. J. & K.
Fig. 3. is a side and sectional view of that part of the apparatus corresponding
with the letters B. C. D. E. F. & G.
Referring to the drawings Fig. 1, A is the board fixed to the door. B, is the
baize pad which fills up the groove. C. is the wrought iron rod fitted into a
bracket in the board with two lugs (D). E. is the two armed lever which hangs
in a bracket F. H. is the rod which connects the top part of the lever. J. is the
lever to which the said rod is fitted. K. is the bracket in which the said lever
swings. L. is the bracket embedded flush with the door post.
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
A draught excluder for doors which works automatically by a combination of
levers and rods as above described and that the board attached to the door,
excluding the draught, can be lowered or raised by the action of the fittings,
whenever the door is closed or opened.
