PROVISIONAL SPECIFICATION.
Contrivance for the Utilization of Door Mats for the Exclusion of
Draught.
I WILLIAM FITZJOHN CRISP of Waynflete Whetstone in the County of Middlesex
Gentleman do hereby declare the nature of this invention to be as follows :-
To the back of any mat and usually parallel and near to one or both of its longer
edges I attach a sleeve of webbing. In one of these sleeves I insert a movable metal
or wood lath cut to a length very nearly equal to the width of the opening of the
doorway for which the mat is intended.
On each side of the doorway opening near to the floor and usually near to the
rebate in which the door is hung I place a metal shoe slotted or recessed horizontally
to receive the ends of the lath; and I attach the shoes to the sides of the doorway-
opening or to the floor.
The combination of mat, sleeve, lath and shoes operates to exclude draught when
the ends of the lath are placed or sprung into the shoe-slots or recesses and one
edge of the mat is thereby held in contact with the outer face of the door when
closed.
The sleeve may be formed out of the substance of the mat at the time of manu-
facture, or a series of loops may be substituted for the sleeve.
The screw holes provided in shoes for fixing same may be slotted to allow of
adjustment.
The section of the lath may be flat, bevilled, oval, semi-oval, convex, concave or
corrugated.

Contrivance for the Utilization of Door Mats for the Exclusion of
Draught.
I WILLIAM FITZJOHN CRISP of Waynflete Whetstone in the County of Middlesex
Gentleman 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 has reference to means for holding door mats in any assigned
position as against accidental displacement by traffic. It follows that when a mat, as
part of this contrivance, is held with one of its edges in close contact with the lower
portion of the outer face of a closed door any draught under that door for the length
of the mat employed will thereby be excluded.
The arrangement consists of :-a sleeve, preferably of webbing, attached to the back
of any mat and usually parallel and near to one of its longer edges; a movable lath,
preferably of metal, for insertion in the sleeve, cut to a length very nearly equal to
the width of the opening of the doorway for which the mat may be intended; a pair
of metal shoes, preferably adjustable, attached to the door linings near the floor (or
attached to the floor) and slotted or recessed horizontally to receive the ends of the
lath.
In operation, the lath is inserted in the sleeve attached to the mat which is then
laid approximately in position, finally, one end of the lath being placed in the recess
of a shoe the lath is sprung to enter its other end into the recess in the opposite
shoe

page_text: In the annexed drawing is illustrated a modification of my invention.
Like letters indicate similar parts in all the figures.
Fig. 1 general plan or horizontal section of a doorway with door closed and mat
approximately in position, shoes are shewn fixed to door linings, and lath and sleeve
indicated by dotted lines; next the opposite edge of the mat an extra sleeve, also
dotted in, is intended for use when mat is turned about.
Fig. 2 front elevation of shoe and transverse section of lath. (The shoe is shown as
attached to door lining but it may be inverted and fixed to floor; the lath may be of
any convenient section.)
Fig. 3 transverse vertical section of shoe, and end of lath in section.
Fig. 4 horizontal section of shoe taken through recess, and plan of end of lath
with corners slightly rounded.
Fig. 5 plan of end of sleeve (inverted) formed of two thicknesses of webbing
eyeletted together, (but stitching may be substituted) the corner of under webbing is
turned down to facilitate entrance of lath; attachment to mat is intended to be made
by thread stitches at each eyelet. (The sleeve may be formed of one thickness of
webbing or of a series of loops, or out of the substance of the mat at the time of
manufacture.)

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
1. Providing means for holding a door mat in any assigned position, and if with
one edge of the mat in contact with the outer face of a door when closed then to
prevent draught thereunder for the length of the mat employed; such means
consisting of a sleeve attached to or forming part of a mat, a lath for insertion in
the sleeve, and a pair of shoes attached to the door linings or to the floor and
recessed to receive the ends of the lath when sprung into position.
2. The sleeve, lath and shoes in combination with a mat substantially as herein-
before described and illustrated in the drawing annexed.
Dated this Fifth day of May 1890.
