page_text: I, WILLIAM EDMUND SHEFFIELD, of 77, Church Street, Stoke Newington, in
the County of London, Accountant, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in draught excluders particularly adapted
for all kinds of doors.
In carrying out the invention a U or other suitably shaped base-plate is sunk
in the floor in a position underneath the bottom of the door when closed. The said
U or other shaped base-plate is provided with a bar the upper face of which is
advantageously convex and which is supported upon a number of springs advan-
tageously passing up into grooves in the underside of the said bar and resting
with their other ends upon washers supported upon the bottom of the base plate.
Screws pass up through the washers into the substance of the bar.
With this arrangement when the door is closed its lower edge presses upon the
upper face of the bar which is held well in contact therewith by the aforemen-
tioned springs.
To adjust the device for different depths of space between the door and floor it is
only necessary to turn the screws which fasten the springs to the sliding bar.

I, WILLIAM EDMUND SHEFFIELD, of 77, Church Street, Stoke Newington, in
the County of London, Accountant, 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 draught excluders particularly adapted
for all kinds of doors.
In carrying out the invention a U or other suitably shaped base-plate is sunk
in the floor in a position underneath the bottom of the door when closed, and in
the groove of this base plate is located a bar which is advantageously of convex
shape on the upper face and supported upon a number of springs which at one
end pass up into recesses in the underside of the said bar and with their other
[Price 8d.]

page_text: ends rest upon washers supported upon the bottom of the base plate. Screws pass
up through the washers into the substance of the bar.
With this arrangement when the door is closed its lower edge presses upon the
upper face of the bar which is held well in contact therewith by the aforemen-
tioned springs.
To adjust the device for different depths of space between the door and floor
it is only necessary to turn the screws which fasten the springs to the sliding bar.
To enable my invention to be fully understood I will describe the same by refer-
ence to the accompanying drawing, in which:
Figure 1 is a front sectional elevation shewing my invention applied in connee-
tion with a door; and
Figure 2 is a section on the line 2-2 Figure 1.
a is the door and is the floor, is the grooved or channel shaped base-plate
which is sunk into the floor, the said bass-plate, as shewn, being provided with
flanges d, d for facilitating fixing it in position. e is the bar fitted into and capable
of sliding vertically in the channel of the said base-plate, the said bar being
provided with the convex upper surface which in the drawing is represented as
being provided with a metal cap f to protect it from wear.
g, gare the springs upon which the said bar is supported the said springs, as
shewn, having their upper ends projecting into recesses h, h formed on the under-
side of the bar and their lower ends pressing upon washers i, i, screws j, j being
passed through the said washers and into the bar so that by adjusting the said
screws the expansion of the springs can be regulated to permit of the bar being
lifted more or less under their action to permit of its bearing against the bottom
edge of the door.
In practice the bar e may be so adjusted that the door will close over it without
depressing it or, if desired, the said bar may be arranged to project to such an
extent that when the door is closed the latter will strike the curved or inclined
surface of the bar and depress it to the required extent against the springs.
Reference to the drawing will show that the bar with its springs is in no way
attached to the base-plate whereby it can always be lifted out when required for
the purpose of cleaning, repairing or adjusting the parts.
It will be understood that the movable bar extends through the whole width
of the door so that when the said door is closed there is no space between the latter
and the floor.
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:
1. A draught excluder consisting of a channelled base-plate adapted to be in-
serted into the floor and having arranged within it a movable bar supported upon
springs which tend to hold the said bar against the bottom of the door, substan-
tially as described.
2. The manufacture and use of draught excluders, substantially as herein before
described and illustrated in the accompanying drawing.
