PROVISIONAL SPECIFICATION.
An Improved Draught and Weather Excluder for the Bottom of
Doors and Windows.
I, JAMES LISLE Joiner 63 Colden Street Waterhead on the one hand, also, 1,
BEN. LISLE Fitter 52 Stock Lane on the other, both of Oldham in the County
of Lancashire do hereby declare the nature of this invention to be as follows:-
--
The object of our invention is to prevent, Draughts, Dust and Weather entering
any premises by windows or doors (chiefly Doors) and at the same time produce a
Our
stronger and simpler appliance, therefore better than any hither to in use.
invention consists of a suitable length of wood mould, and of a thickness such as
will allow Rabbet of three eights of an inch deep, or more if thought proper. The
width or height of rabbet to be one inch and an half, more or less, as is found most
convenient, In this Rabbet a lath of suitable dimensions is fixed, The manner of
fixing is here described the lath is made with slots of a length and breadth, sufficent
for the insertion of metal hushes to protect the slots in the wood lath from wear and
to reduce friction, The slots beeing made at an angle of Forty Five degrees, so as
to produce a lifting motion equal to its travel or forward motion or any other
angle may be used, This lath is provided with a suitable spring (coiled prefered)
which is sunk in the top edge of lath or in the edge of rabbet and secured Small
screws are then passed through the slots the said lath being then projecting the
required distance past the lower edge of face mould and the same at end, The spring
at this point being of such tension, as to draw back the lath when released, this
appliance may be applied to the front or back of Doors, a bracket of proper angle,
being fixed for it to work on the end of inth so as to push it in It will be seen that
on fixing our invention to the front of doors the projecting end of lath pushes against
the jamb of door frame to which the door is hinged, Thereby having no tendency to
warp the door, and it will be plain the pushing in of the lath will also push
it hard down on step we also fix metal friction plates or bearings between lath and
mould at suitable distances, a strip of felt is used to make a joint.

I JAMES LISLE Joiner 63 Cobden Street Waterhead on the one hand, also [ BEN
LISLE Fitter 52 Stock Lane on the other, both of Oldham in the County of Lancashire
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 :-

Premises by Windows or doors (chiefly doors) and also to produce a stronger and

consist of a suitable length of wood mould, prepared as shown at A this mould
is Bored for screws which secure it to the door, it is also rabbeted out to receve
lath B. The height of Rabbet beeing 2 inches and the depth inch, more or less
as is found most convenient, The afore said lath is peforated to receve the
metal bushes or slots, U, which protect the holes in lath from wear, and at same
time prevent any undue friction. These slots are about one third the thickness of

page_text: lath and are driven in to about the middle, so as to form a recess on each side
of same to receve the heads of screws D. The afore said, Slots, U, is fixed in
the lath diagonally so that the pushing in of the projecting and of lath, produces
a downward motion, equal to its forward motion or thrust, or any angle may be
used. The end of lath which receves the thrust is on the same side of door, as
the door is hinged upon, the aforesaid lath B at this end is provided with a roller
bearing E. to avoid friction as the lath in being pushed in, as inparted to it a
downward motion by reason of the diagonal slots. the coiled spring, G, is also
holding the end of lath firm to door jamb or frame causes an amount of friction,
which causes the roller bearing E to be of the utmost inportance. The diagonal
slots, C, work upon the Screws D which said screws are a fixture in the back of face
mould A. The coiled spring G is secured to the top edge of mould A about the
middle, and also to the top eilge of lath B, so to enable the band, to be changed easily,
And as the slots (, are in the middle of the thickness of lath B this can be quickly
accomplished by takeing out the screws D, and the screw F, then reversing the lath,
and screwing on as before. Fig. 1 shows the appliance as it is, when door is
Fig. 2 shows the appliance when door is shut. Fig. 3 shows an other method which
is not so good, as the screws heads get pushed against the door and are pushed off
lath, and, are useless in a few days, there is also nothing to keep the lath firm to the
side of face mould. And we are very much in favour of carring out our invention
as described in Figs. 1 and 2.
:
And
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is performed, I declare that what we
claim is
1. The roller bearing E is new to this kino of appliance, and at first we thought
it would need more then one, Roller bearing or plates, and therefore in our provisional
specification used the words, Fricton plates or bearings, which we still reserve, but
in practice one is sufficient.
2. The diagonal slots, C, are new, also the method of fixing same, so as to
enable the lath B to be reversed, and are of general use, as by the aid of these
slots in connection with the roller bearing, we are able to despence with the
complicated arrangment of levers and cranks, as used hitherto.
Dated this 1st day of June 1889.
