WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 398,187, dated February 19, 1889. Application filed April 7, 1888. Serial No. 270,000. I (No model.) Patented in England August 22, 188'7,No.11,410.

To 12 whom it may concern:

Be it known that we, JOHN CHARLES REID and JAMES REID, subjects of the Queen of Great Britain, and residents of Leeds, in the county of York, England, have invented certain new and useful Improvements in VeathenStrips, (for which we have obtained a patent in Great Britain, No. 11,410, dated August 22, 1887,) of which the following is a full, clear, and exact specification thereof.

Referring to the drawings, Figure l is an isometric view of a door-frame and door, illustrating the application of ourinvention. Figs. 2 and 3 are sections of a portion of the doorframe and door, showing the position of the weather-strip when the door is open and closed, respectively. views, on a larger scale, showing the springbox and the part thereof that serve to connect it with a door. Fig. 6 is a top plan view of the spring-box, the covering-plate being removed. Fig. 7 is a like view illustrating the arrangement of the spring-box to impart to the weather-strip a motion at an angle to a straight line. Fig. 8 is an isometric view of a portion of a door-frame and door, illustratin g a mode of imparting motion to the weatherstrip. Fig. 9 is a section of a. portion of a door-frame, illustrating a different mode of applying the weather-strip. Figs. 10 and 11 are transverse sections of the spring-box and Weatherstrip, taken on lines a; a: and y 1 respectively, of Fig. 6; and Fig. 12 shows the beveled plates at the ends of the weatherstrip shown in Fig. 10.

Like letters of reference indicate like parts wherever such may occur in the drawin The invention relates more particularly to 1 means for rendering doors of dwellings air or draft proof; and it consists in the combination, with the door and door-l:'ran1e,of springactuated weather-strips, whereby said strips are held against their bearing-surfaces to prevent thopassagc of air and dust, substantially as hereinafter fully described, and as set forth in the claims.

Referring to Fig. 1, A indicates the door- I casing; 13, the door, and G the weather-strips.

As shown, one of the weather-strips is secured to the lower edge of the door, one to the jamb- Figs. 4 and 5 are isometric lining a, and the other to the lintel-lining at. These weather-strips are arranged to slide longitudinal axis or in a direction at a more or less acute angle to said axis. For instance, the weather-strip at the bottom edge of the door and that on the lintel-lining a" of the casing are so arranged as to move upwardly and outwardly, respectively, and, if properly mitered or rabbeted, form a tight joint with the weather-stri p 011 said j amb-casing a, which latter strip moves in a plane at right angles to the vertical.

The Weather-strips are so connected to their respective supports as to project slightly beyond the edges thereof, and are held in that position by a spring. For instance, the Weather-strip along the lower edge of the door projects beyond said lower edge, so that when the door is closed the lower horizontal edge of said strip will come in contact with the sill s, the weather-strip being forced upwardly by contact with the sill, the spring-power holding the bearing-edges of the strip firmly in contact with the sill and the weathenstrip on the lock side of the jamb-casing a.

The weather-strip on the janib-casing and lintel-lining project over the rabbet into which the door fits, so that when the door is closed said strips will be forced back against the stress of their springs, by which they will be firmly held against the vertical and upper horizontal edges of the door.

The weather strips may, if desired, have their bearing-edges covered with felt, cloth,

rubber, or equivalent material, a, to make a more perfect joint, and said weather-strips, instead of being secured to the outer face of the door and casi n g, may be secured in grooves or recesses formed in the under side of the door or lintel lining or in. the jainb-lining, as shown in Fig. 9, so as not to deface the door or frame, in which case the closing of the door will force the weather-strips into the recesses against the stress of their springs, which will hold the bearing-faces of the strips fi Ally against the sill and vertical and upper hori- 1 zontal faces or edges of the door, the jambstrip being suitably cut away, so as not to interfere with the lock.

either in a direction at right angles to their The weather-strip along the lower edge of the door may also be so actuated by its spring as to hold it off the sill, and in this case abutment plates or stops D, provided with beveled actuating-faces d, as shown in Fig. 8, may be secured to the jamb-lining on the lock and hinge side of the door, respectively, the weather-strip being provided at its opposite ends with similar plates, 0, provided with inclined or beveled faces 0 Fig. 12, that come in contact with the inclined faces on the abutmentplates, whereby the weather-strip is forced down on the sill in the act of closing the door.

The means employed to give play to the weather-strips will now be deseri bed. These consist of a box or casing, .1, provided with an encompassingflange, 2, having screw-holes c, said casing being divided into two parts,.l and 2, by a partition, c This casing is fitted in. a slot in the weather strip 0, with its flanges on the inner side of said strip and flush therewith, and is secured to the strip by means of screws passing through the screwholes 6 of the encompassing-Iiange of the easing, which thus forms substantially an integral part of the weather-strip.

F is a plate that has perforated or hollow lugs f f formed thereon for the passage of the fastening-screws.

.lVhen the two parts E and F are assembled, the perforated ing 1 projects into part 1, while the lug f projects into the part 2 on opposite sides of the partition 8 and between the lug and the partition 0 is interposed a spring, S. To prevent the spring from fallin g out of the casing E, we preferably make the same'tapcring in cross-section, as best shown in Figs. 10 and 1], the perforated lugs be ing similarly shaped and preferably rectan gular-to afford better bearings therefor within the casin g, as well as for the spring S. This plate F is rigidly secured by screws f to the part to which the weather-strip is applied, as to the door, jamh, or lintel-cas'ing, as hereinbefore described, and it is obvious that this plate serves as a retaining device for the strip, allowing it at thesame time a certain amount of motion limited by the space 2 and its contained spring. It will also be .readilyseen that according to the position of these parts relatively to the weather-strip and the part to which it is applied said strip will be held projected beyond the edge of such parts or not. For instance, if the weather-strip is to be applied along the lower edge of the door, so that the bearing-edge thereof will project beyond. said lower edge of the door, so that said strip will be forced up against the stress of the spring by contact with the sill s on closing the door, the spring S is placed between the partition 6' and the lugf If, on the contrary, the strip is to'be held flush with the edge of the door, and is to be forced down against the stress of its spring by the plates D, then the spring S is placed between the partition c and the lug f, as will be readily understood.

Undersome circumstances it may be desirable to impart to the strip (1 a motion on a tion in its application to doors; butit will be understood that we do not limit ourselves to such, as it may be applied for like purposes to many other objectsas, for instance, to windows or to box-lids to render such more or less air-tight and dust-proof.

Having described our invention, what we claim is F l. -The combination, witha door or thelike and a weather-strip, of a casing rigidly connected therewith and having its open chamber divided by a partition, of a guide-plate provided with perforated lugs extending into said chamber on opposite sides of the partition, said guide-plate being rigidly secured to the door by screws passing through said perforated lugs, and a coiled spring arranged in said chamber to exert its power upon one of the lugs, substantially as and for the pur-' poses specified.

2. The combination, with a door or the like and a weather-strip, of a casing rigidly connected therewith and having its open chamber made tapering inwardly and divided by a partition, of a guide-plate provided with correspondingly-tapering perforatedlugs extending into said chamber 011 opposite sides of the partition, said guideplate being rigidly secured to the door by screws passing through said perforated lugs, and a coiled spring arranged in said chamber to exert its power upon one of the lugs, substantially as and for the purposes spccilied.

The combination, with a movable element and a stationary element, of means for forming a tight joint alongthe meeting edges of said elements, comprising a Weatherstrip, the flanged easing E, secured thereto, said. casing being made tapering in cross-section and divided into two unequal parts by a stationary partition, the guide-plate F, connected with the movable element and provided with correspondingly-tapering perforated lugs f f and the coiled spring S, said parts being constructed and arranged for co-operation substantially as and for the purposes specified.

In testimony that we clai m. the foregoing we have hereunto set our hands this 19th day of September, 15187.
