TO ALL WHOM IT MAY CONCERN: 1

Be it known that I, BENJAMIN F. AVERILL, of Dunkirk, in the county of Chautauqua, and State of New York, have -invented a new and improved Weather-Strip; and I do hereby declare tliat the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to'the accompanying drawings, forming part of this specification.

Figure 1 is a side view of the mechanism by` which the weather-strip is operated.

Figure 2 is a top view of the same from a section taken through the line :z: x, fig. 1.

Similar letters of reference indicate'corresponding parts.

The nature of this invention relates to weather-strips for shutting out the draughts of cold air under the bottoms of doors.

It consists'of a movable plate, provided with certain mechanism by which the said plate is made to shut downward and close the crack between the door and the sill, and to rise again when the door is swung open. It consists of the lever-and-spring mechanism, in combination with the said movable strip, the construction and operation of which will be duly set forth in the following.

In the accompanying plate of drawingsfthe. door is shown at A, B being the Acasing of the same.

The movable strip C is a plate oi'3 sheet metal, luted at its upperedge to it under a reversely-iluted plate, D, aixed to the door, as shown, whereby a slidingjoint is obtained, which enables the movable strip C to work up and down, and when down, in contact with the floor, the edges ot' the ilutings will be brought in contact, and thereby form a joint to prevent a draught between the ilutings. l

The lower edge of the strip C rests against a bead, z', forming part of the sill, and the draught excluded. at that point.

The mechanism by which the strip is operated' consists of two levers, E E, pivoted to the door at b b', as shown. The pivot b, which is nearest the hinges of the door, is merely a screw, upon which the lever E vibrates, but the pivot b is aiixed to the lever E', and turns when the latter vibrates. By the vibration of these levers the strpC is raised and lowered, and the said vibration is performed against the tension of the nprights ff,A

which are inserted into the door, and are coiled once or more around the screws e c, and pass under the levers, terminating in shoes mm, against which th'e levers work. The strip C is attached .to thc levers by means of studpins a a, as shown, which work in holes or slots in the said strip, and are provided with heads, as shown, to keep the strip from coming oii'. l

In iig. 1, a portion only of the strip C and plate D is shown, the remainder being broken away to exhibit Y the lever-mechanism behind them. y

The'means by which the strip may be actuated downward when the door is in the act of being closed are various, but two only of such devices are shown. i

The first consists .in vibrating the lever E by an arm, g, atlxed on the pivot b, and a bevelled projection, It, aihxed to the casing B,- as shown.A y V When the door is nearly closed, the arm is raised by the bevelled projection hin a manner similar to that of a door-latch, and the lever E is vibrated by its pivot b, thereby bringing the end of the strip down in contact with the bead 2': The vibration of the said lever continuing,v the whole strip is brought down horizontally, and with thewholc lower edge in contact with the bead ,Yby the actgion of the stud a of the lever E', for .when the end of the strip has come in contact with the sill or bead,I that point of contact constitutes a fulcrum for a lever of the third order, the strip acting as alever, and the stud not"` the lever Ebeing the point of application of the power.

The second modification of this device may be employed. It consists in placing a projection, d, in such a position that it will impinge against some point ot the lever E, above'the vibrating-centre of that lever, as shown at n, when the proximate end of the strip will descend iirst, and the' other be made to follow in the man .ner above described.

I claim as new, and desire tri-secure by Letters Patent- 1. The Weather-stripconstructed :Le described, of the strip C, luted along its upper edge to work undel' ,Secured to the door, the plate C being hung upon the headed v and in contaet with the reversely-luted plate-D late, which levers are p ivo'ned to the door at b', and held up pins a, affixed to thelevers E E beneath the p all, arranged asdescribed for the purpose specified.

2. The arrangement of the screw d, projection n upon the lever E, the pivoting-pin 6 upon the lever E', the armgand incline L, all operating as described, to depress the uted plate C egnt the tension of the springs as herein described for the purpose specified. l
