PROVISIONAL SPECIFICATION.
Improvements in Thresholds and Weather Strips therefor.
Nebraska,
I, WILLIAM MONTGOMERY BARGER, of Hebron, Thayer County,
United States of America, Salesman, do hereby declare the nature of this inven-
tion to be as follows:-
The object of this invention is to provide new and useful improvements in
means for preventing draughts, rain, or snow from entering beneath a door.
The invention comprises a ridge which is made along the threshold at a point
covered by the door when closed.
A strip of wood, of about the same thickness as the ridge is high, is fitted in
the door way against the ridge and has its upper surface bevelled down to its
outer edge. A piece of sheet metal is secured to the strip and is hinged at the
outer edge of the strip to the threshold; the piece of metal projecting beyond
the inner edge of the strip and over the ridge, at which point it is bent down-
wardly at right angles. Suitable springs are interposed between the overhanging
piece of metal and the top of the ridge, to keep the former normally pressed
Set-screws, passed through the
upwards against the under edge of the door.
strip into the threshold, limit the movement of the strip.
In order that the strip may not cause an abrupt obstruction in the door way,
a fixed strip, bevelled as aforedescribed, may be fitted to the threshold on the
opposite side of the ridge. Or, if desired, the strip and threshold may be sunk
so that it is approximately level with the floor when the door is closed, and only
slightly raised above it when the door is open.

Improvements in Thresholds and Weather Strips therefor.
I, WILLIAM MONTGOMERY BARGER, of Hebron, Thayer County, Nebraska,
United States of America, Salesman, do hereby declare the nature of this inven-
tion 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 certain new and useful improvements in thresholds
and weather strips therefor; the object of the invention being to provide exceed-
ingly efficacious and cheap means for preventing draughts, rain, or snow, from
entering beneath a door.

page_text: Reference being had to the drawings hereunto annexed:-
Fig. 1 is a plan of a threshold and weather strip constructed in accordance
with my improvements.
Fig. 2 is a cross section taken on the line - of Fig. 1.
Fig. 3 is an end elevation shewing the position assumed by the movable parts
when the door is closed.
A
Fig. 4 is a view in perspective of a simplified form of the invention.
The threshold 1 is preferably bevelled towards its forward edge as shewn.
piece of sheet metal 2 is secured to the upper surface of the threshold by means
of screws 3, 4. A wooden strip 5 extending the length of the threshold and
provided with a ridge 6, is retained in place by the screws 4.
A piece of sheet metal 7 is severed at points 8 to permit of its centre portion
being bent inwards at right angles at 9, and at a point 10, horizontally to the
point 11, where it is bent upwardly as shewn at 12 into alignment with the end
pieces 13. A wooden strip 14, having its upper surface bevelled as shown, is
retained between the centre portion of the piece of metal 7 and the end pieces 13,
and is secured by screws 15. A hinge-pin 16 passed between the metal 7, at 11,
and the strip 14, serves to hinge the latter to the threshold, the pin passing
through eyes 17, preferably formed of a single piece of sheet metal bent to form
the eye 17 and having its ends passed through an aperture in the metal 2 and
bent at right angles thereunder.
The forward part of the piece of metal 7 extends over the ridge 6 and is bent
at right angles to extend over its other side as shewn at 18. A groove 19 on the
upper surface of the ridge 6 serves to retain bowed flat springs 20 which tend
to keep the hinged strip 14 elevated. The distance to which the strip is raised
is limited by the screws 21 projecting from the under side of the strip 14, through
apertures 22, and into the clearance openings 23. The heads of the screws 21
rest normally beneath the bifurcated ends of the keys 24. which are slidable
in grooves in the underside of the strip 5, slotted at 25 to clear the screws 4,
and bent up at 26 to form convenient means for withdrawing them, as shewn
to the left of Fig. 1, when it is desired to raise the strip 14 to attend to the
springs or adjust the screws 21. The withdrawal of the keys is limited by the
screws 4, and they will not readily move from their normal position on account
of the friction caused by their bending at the point 27 to pass through the
aperture 28 in the metal 2, into the recess 29 in the threshold 1.
In Fig. 4 I have shewn a simplified form of the invention, and it consists
merely of the modified form of threshold 30 formed integral with the ridge 6,
or having the latter secured, thereto. In this form, the inner portion of the
piece of metal 7 is cut away, and the end pieces 13 hinged at 31 to the thres-
hold 30. Screws 32 pass loosely through the strip 14 into the threshold 30 so
that the former can move freely thereon, its movement being limited by the
heads of the screws. Springs are arranged beneath the metal 7, as shewn in
Fig. 2, or spiral springs may be arranged under it or around the screws 32
beneath the strip 14, if preferred.
When the door 33 closes over the strip 14 it will be depressed, as shewn in
Fig. 4, and inasmuch as it is normally pressed upwards into close contact with
the lower edge of the door, draught will be prevented from entering there-
between.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:-
(1) The hereindescribed improvements in thresholds and weather strips there-
for, said improvements comprising a ridge secured longitudinally of the thres-
hold, a strip hinged longitudinally adjacent to said ridge and provided with a
forwardly projecting piece of metal extending over said ridge, springs arranged
to retain the piece of metal and hinged strip normally elevated, and means
}

page_text: such as a screw for limiting the upward movement of said strip, all substan-
tially as and for the purposes herein before set forth and illustrated in the drawings
hereunto annexed.
(2) The hereindescribed improvements in thresholds and weather strips there-
for, said improvements comprising the threshold bevelled towards, its forward
edge, a piece of sheet metal conforming to and secured to. the upper surface of
said threshold, a wooden strip superimposed on the metal aforesaid and secured
longitudinally of the threshold, a ridge on said strip, a movable strip arranged
adjacent to the fixed strip aforesaid and hinged to the piece of metal aforesaid,
a piece of sheet metal encompasing said movable strip and projecting forwardly
therefrom over the ridge aforesaid, springs situated between the upper surface
of the ridge and the under side of the forwardly projecting piece of metal, screws
projecting from the underside of the movable strip into clearance openings in
the threshold, and bifurcated keys adapted to engage the heads of said screws
and capable of being withdrawn in order to raise the movable strip, all substan-
tially as and for the purposes hereinbefore set forth, and illustrated in the draw-
ings hereunto annexed.
