UIQHM J. M. LEWIS WEATHER STRIP Nov. 24, 1936.

Filed Nov. 9, 1935 3 Sheets-Sheet 3 Inventor L/Z/z/zewz/'S/ Patented Nov. 24, 1936 UNITED STATES PATENT GFFICE 6 Claims.

The invention relates particularly to a weatherstrip adapted to close completely the space between the bottom of a swinging door, windowframe, or the like, and the sill, floor, or other base with which such a part should have a tight fit when closed.

It is an object of the invention to provide a Weatherstrip structure that vwill push a laterally slidable packing-strip against the sill, oor, or equivalent part when the door or the like with which it is associated is closed, and which will retract the strip therefrom immediately upon beginning of opening movement, whereby drag of the strip on the sill, floor, or the like, will be avoided.

When considered with the description herein, the characteristics of the invention are apparent in the accompanying drawings, forming part hereof, wherein an adaptation of the invention to a door is disclosed, for purposes of illustration.

Although the disclosures herein are considered to exemplify a preferable embodiment of the invention, it is to be understood that it is not the intention to be limited necessarily thereto in interpretation of the claims, as modifications and adaptations within the limits of the claims can be made without departing from the nature of the invention.

Fig. 9 is a fragmentary View, partly in section, showing the pin for holding movable parts in open position during installation of the device.

In the drawings, A designates a door, B the upright part of the frame or post on which the door is hinged, and C the sill or floor below the bottom of the door, these parts being of usual and conventional form.

The device includes a housing, preferably` of sheet metal, formed with a plate or front wall I, a top II, and an upstanding flange I2 having holes I3 through which suitable fasteners are driven into the door to secure the device in place thereon. At each end, the material of the hous- 5 ing extends rearwardly as an end Wall I4 and thence inwardly as an inner wall I5 substantially parallel with the front wall or plate. The end walls afford mountings for an actuating bar, and the end and inner walls and the portions of the l0 front wall directly opposite the latter constitute guides or slides for a packing-bar, as now described.

An actuating-bar I6, preferably rectangular in cross-section, is positioned inside of the housing l5 and extends at one end through a correspondingly shaped hole in one of the end walls, and on its outer end it has a head I'I. The other or inner end portion of the bar is formed with a longitudinal hole or bore I8. A guide-pin I9, mounted 20 at one end on the other end wall of the housing, extends into the bore of the bar, and thus slidingly supports the inner end thereof.

A coil-spring 26, interposed between the inner end of the bar and the opposed housing-wall and disposed around the pin, urges the bar in a direction away from that wall and tends to protrude the headed end of the bar to its full extent.

A packing-bar 2|, below and substantially parallel with the actuating-bar, extends at its ends into, and is movable laterally in, the guides or slides at the ends of the housing. The packingbar preferably is in the form of a metallic channel member, as shown particularly by Fig. 6, which envelopes, clamps, and holds the upper portion of a packing-strip 22, and the lower portion of the strip extends downwardly therefrom. The packing-strip is of felt or other material such as commonly used for like purpose in the weatherstrip art, but it is somewhat thicker than the strips ordinarily employed.

Links 23, one near each end of the device, are connected pivotally by

pins

24 and 25, respectively, to the actuating-bar and packing-bar, the disposition of the links being such that they are inclined to the bars when the packing-bar is lifted or retracted in response to the urge of spring 2E) forcing the actuating-bar outwardly (to the right when viewing Figs. 4 and 7) and in response also to the urge of springs 26.

The latter springs are elongated ones tensioned to straighten, and they may be spring wire as shown. Each of them has an end 21 extending under the actuating-bar, between its ends it curves over an upper link-pin 24, and at its other end 28 it extends under the lower pin 25 of the same link. With this arrangement of the springs 26, in which they are deflected against tension from the straight condition, they exert a direct upward urge against the lower link-pins and thus against the packing-bar.

The parts are proportioned and coordinated so that, when the packing-bar is against the actuating-bar, and thus limited in its upward or retractive movement, the lower edge of the packingstrip is coincident with the lower edge of the front housing-plate l0, and thus the strip is housed within the housing. This contact also limits the outward movement of the actuatingbar.

When the device is to be put on a door or the like, the packing-strip is held at the outward limit of its movement, which is determinedvby contact of the head Il of the actuating-bar with the adjacent end wall of the housing. This retention of the parts may be by any suitable means, for example by that shown by Fig. 9 The upper Wall l l of the housing has a hole through which a pin 29 extends into a hole in the actuatingbar, these two holes being positioned to become aligned when the actuating-bar ispushed inwardly to the limit and thus the packing-bar is protruded to its limit.

The head l1 of the actuating-bar I6 is in the form of a bumper-plate, which extends rearwardly and laps the edge of the door at the hinge side, as seen more particularly in Fig. 8.

With the packing-strip held outwardly by the pin 29, and the door being shut, the device is placed against the lower side of the door, with the packing-strip resting on the sill or floor beneath or pushed down thereagainst, and with the rearwardly extending portion of the bumperplate slipped into the crack between the edge of the door and the abutting surface of the doorframe structure. This easily determines the position the device should have on the door, both with respect to the sill or :door and to the edge of the door and the surface of the stationary part opposite thereto. The device then is secured in place by driving screws or other suitable fasteners through the holes in the flange l2'. The pin then is Withdrawn, whereupon the parts are free to function.

The parts are arranged and proportioned so that they remain in those positions until the door is nearly closed, when the head of the actuating-bar contacts with the side of the adjacent door-frame member. Thereupon, with the door continuing to swing closed, the bar is pushed inwardly, and, by the time the door is completely closed, the packing-strip has been pressed, in protrusive direction, through the instrumentality of thelinks, down against the sill or floor, and thus a tight closure at the bottom of the door is afforded. o

As soon as the door begins to swing open, the actuating-bar begins to be released from its retracted position, the packing-strip begins to lift from the sill or floor and thus retracts to a position in which it does not contact with' and drag on the floor as the door continues to swing open.

Ordinarily, the head of the actuating-bar will not mar or sink into the door-frame member against which it contacts, particularly if the frame is of hard wood. However, if it is necessary to protect the frame material from the head, that easily may be done by driving a metal headed article, such as a thumb-tack for example, as designated by 30, at the place of head contact.

The device is made in various lengths toconform to the widths of the standard types of doors, swinging windows, and the like for which they are intended.
