of Wind, Rain, or Dust Beneath Doors.
We JAMES KENYON, JONATHAN BARNES, and RICHARD WALTON KENYON all of
Accrington in the County of Lancaster, Machinists, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in the apparatus for fixing to the bottoms of
doors known as draught preventers.
These draught preventers are made in two pieces hinged together one piece being
rigidly secured to the door and the other projecting downwards from it occupies the
space between the bottom of the door and the floor. This lower piece is raised or
pressed forwards upon its hinges by means of a spring or springs and closed down on
coming in contact with the jamb or door frame as the door closes. As hitherto
constructed these have been made with spring hinges which are expensive or with flat
or plate springs which on being exposed to the action of the weather soon corrode
and break besides which in both cases special fitting is required to adjust the spring in
position.
Our present invention is designed with the object of obviating these objections and
providing a dust preventer having a strong and durable spring without increasing the.
cost of production or at a less cost than hitherto.
It consists essentially in constructing the dust preventer with a spring of metallic
wire or its equivalent placed approximately longitudinally at its back one end being
connected with the fixed part and the other with the movable part so that the closing
or lowering of the latter exerts a twisting action on the spring. which when released
operates to raise the movable part of the preventer to allow the door to open and close
without obstruction.
In carrying out the invention we prefer to construct the preventer of two parts in
usual form hinged or jointed together with light metallic hinges. And we provide a
spring preferably of steel wire one end of which is attached to the fixed part of the
apparatus and the other end to the movable part of it. As a simple and inexpensive
 ܼܝ

page_text: method of fixing we bend a short length of the wire spring at each end at right angles
to its longitudinal axis with the bent end pieces in a plane inclined to each other and
insert the bent ends into holes made in the wood.
It is of course obvious that the spring may be attached in a variety of ways such as
by making an eye to receive a screw or pin or by fixing in a bracket which will prevent
it turning on its axis nor is it essential that the spring should be a perfectly straight
piece of wire as the wire may be somewhat twisted or coiled so as to give a greater
length of wire and more elasticity of spring but we at present prefer to arrange it as
above described.

page_text: Improvements in or relating to Apparatus for Preventing the Passage
of Wind, Rain, or Dust Beneath Doors.
We JAMES KENYON JONATHAN BARNES and RICHARD WALTON KENYON all of
Accrington in the County of Lancaster Machinists, 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 improvements in the apparatus for fixing to the bottoms of
doors known as draught preventers for the purpose of preventing the passage of wind,
dust or rain beneath the door.
These draught preventers are made in two pieces hinged together one piece being
rigidly secured to the door and the other projecting downwards from it occupies the
space between the bottom of the door and the floor. This lower piece is raised or
pressed forwards upon its hinges by means of a spring or springs and closed down on
coming in contact with the jamb or door frame as the door closes. As hitherto
constructed these have been made with spring hinges which are expensive or with flat
or plate springs which on being exposed to the action of the weather soon corrode and
break besides which in both cases special fitting is required to adjust the spring in
position.
Our present invention is designed with the object of obviating these objections and
providing a draught, dust, or rain preventer having a strong and durable spring without
increasing the cost of production or at a less cost than hitherto.
It consists essentially in constructing the dust preventer with a spring of metallic
wire or its equivalent placed approximately longitudinally at its back one end being
connected with the fixed part and the other with the movable part so that the closing
or lowering of the latter exerts a twisting action on the spring which when released
operates to raise the movable part of the preventer to allow the door to open and close
without obstruction.
Referring to the annexed drawings,
Fig. 1 is an elevation looking from the back showing position of the apparatus when
the door is closed.

Figs. 6 and 10 sectional elevation on line z―z.

Figs. 12 and 13 elevation and plan respectively of the spring D.
As will be seen from these drawings we construct the apparatus of two parts A and B.
in the usual form. These parts are hinged or pivoted together with light metallic
hinges C of any ordinary construction without springs. At the back of the apparatus

page_text: we connect a spring D which when the door to which it is attached is open causes it to
assume the position shown in Figs. 2. 5. 6. 9 and 10. The spring D as shown in
Figs. 11. 12. and 13 in its simplest form consists of a length of tempered steel wire
bent for a short distance at each end d d' at right angles to its longitudinal axis, the
end d being in a plane inclined preferably at about right angles to that in which the
end d' is situated. To attach or connect the spring D to the apparatus one end say d
is driven or inserted into a hole made in the fixed part A and the other similarly
connected with the part B.
It is of course obvious that the spring may be attached in a variety of ways such as
by making an eye to receive a screw or pin or by fixing in a bracket which will prevent
it turning on its axis, nor is it essential that the spring should be a perfectly straight
piece of wire as the wire may be somewhat twisted or coiled so as to, give a greater
length of wire and more elasticity of spring but we at present prefer to arrange it as
above described.
The draught preventer is operated in the usual way the part A is screwed to the
door the part B projecting below it. When the door is closed the metal catch E abuts
against an obstructing piece on the jamb of the door and draws down the movable
piece B to the position shown in Figs. 1 3. 4. 7 and 8. On opening the door the
spring causes it to assume the position shown in figs. 2. 5. 6. 9 and 10.
Having now particularly described and ascertained the nature of the said invention
we wish it to be clearly understood that as hereinbefore stated it is customary to make
draught preventers in two parts one moved by a spring and that we are well aware
that springs exerting a force when coiled or twisted have been used for various
purposes and consequently we make no specific claim therefor nor for any of the parts
herein described taken separately but we declare that we claim.
1. A draught preventer constructed with plain metallic hinges and having a spring
of metallic wire placed longitudinally at its back and connected with the several parts
so that the movement of one of them will exert a twisting action on the spring substan-
tially as described.
2. The use in combination with a draught preventer formed in two parts of a
metallic wire spring, straight, or more or less coiled, placed with one end in connection
with the fixed part, and the other end with the movable part, so that the movement
of the one part of the apparatus exerts a twisting or coiling action on the spring
substantially as described and shown.
