IMPROVEMENTS IN WEATHERBOARDS AND DRAFT EXCLUDERS
Year: 1885

page_text: I, WILLIAM BURROW SHORLAND of 25 Albert Street, Manchester in the County
of Lancaster. Estate Agent, do hereby declare the nature of said Invention for
". IMPROVEMENTS IN WEATHERBOARDS AND DRAFT EXCLUDERS" to be as follows:-
It consists of improvements in that class of weatherboards in which a slip of
wood or other material is sustained in its place by a central spiral spring and two
short levers (one end of which is pivoted to the weatherboard and the other to the
slip of wood or other material) when the door is open, and is pushed down by
the pressure of the doorcheek upon the end of the slip of wood when the door is
closed. In my improved weatherboard I attach a short rod of metal or other
suitable material to one of the short levers the other end of which is suitably
adjusted so as to press upon the doorcheek or jamb or upon a metal plate or stud
upon the doorcheek or jamb when the door is shut and so press down the slip of
wood or other material instead of allowing the end of the slip to be pressed by the
doorcheek as heretofore. I may also in suitable cases use angular instead of
straight levers so as to obtain the same result with less friction the end of the rod
resting against or being pivoted to the upper end of the angular lever.

I also may use weights attached to the levers to raise the slip instead of springs
as heretofore. By these improvements the door is closed with much less friction
and the fall of the slip can be regulated by shortening or lengthening the rod or
by attaching the rod at a greater or less distance from the fulcrum of the lever..

page_text: I, WILLIAM BURROW SHORLAND of Albert Street, Manchester in the County
of Lancaster, Estate Agent, 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 :-
It consists of improvements in that class of weatherboards in which a slip of
wood or other material is sustained in its place by a central spiral spring and two
short levers one end of each of which is pivoted to the weatherboard and the other
to the slip of wood or other material, when the door is open, and is pushed down
by the pressure of the doorcheek upon the end of the slip of wood when the door
is closed.
In my improved weatherboard I attach a short rod of metal or other suitable
substance to one of the levers below its fulcrum, the other end of which the rod
is suitably formed and adjusted to press upon the window or doorcheek, or jamb
when the window or door is shut and so presses down the slip of wood or other
material, or allows it to fall. I am aware that rods of metal have been used before
for this purpose, but they have been attached to the levers above the fulcrums.
The levers may be either angular or straight but I prefer to make them angular,
so as to obtain the same result with less friction. The end of the rod resting
against, or being pivoted to the upper end of the angular lever or connected
therewith below its fulcrum.
By these improvements the door is closed with much less friction and the rise
and fall the slip has is greater and can be regulated by shortening or lengthening
the lever or by attaching the rod at a greater or less distance from the fulcrum of
the lever.
In order that the foregoing may be better understood I send herewith a sheet
of Drawings in which is shown a back elevation of the weatherboard when open.
In this a indicates the short rod, attached or pressing against the lever b below
the fulcrum c the slip of wood or other material d is kept parallel by means of the
other lever e. In this figure the spring f on the rod a keeps the slip raised but
I may substitute a central spring or use a flat spring or weight as I may find
suitable.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed; I declare that what
I claim is:-
The apparatus, substantially as described and shown hereinbefore and in the
accompanying Drawing for the purpose set-forth.
