METALLIC WEATHER STRIP.

Application filed February 14, 1922. Serial No. 586,606.

To all whom it may concern.' p.

Be it knownthat I, LYLE H.-Efrrnn, a citizen ofthe United States, residing at Marietta, in the county of Washington, and State of Ohio, have invented a new and useful Metallic Weather Strip, of which the following isa specification.

This invention relates to weather strips and particularly to metallic 'weather strips..

purpose of effectively sealing the space between the same and the frame, the weather strips being so constructed as to be easily applied in position without the necessityl of removingthe sashes as is usually the case with ordinary strips.

A further object is to provide weather strips which will prevent the sashes from binding in theirtracks or grooves in the window frames, all side play and rattling being prevented by the spring pressure of. the strips at two di'erent po-ints on all sides of the sash.

. A full and complete understanding of the invention may be obtained from a consideration of the following detailed description, taken in connection with the accompanying drawing forming a part of this application; it being understood that while the drawing shows a practical form of the invention, the

`latter is not confined to strict conformity therewith, but may be changedy or modified, so long as such changes or modifications mark no material departure from the salient features4 of the invention, as specifically `pointed out in the appended claims.-

In the drawing, in which similar reference characters-:, vdesignate corresponding parts throughout the several figures:-

Fig. 1 is a vertical section through the upper portion of a window frame havingthe improved weather strip applied thereto, the outer or upper sash being shown in lowered position.

' portion of the strip.

Fig. 2 is a similar view, the sash being elevated to its seat and showing the weather strip engaged thereby.

Fig. 3 is a horizontal sectional View taken on the line 3 3 of Fig. 1, and looking in the direction of the arrow.

Fig. 4 is a -similar view, taken on the line v4 4: of Fig. 2, and looking in the same direction.

Fig. 5 is a detail perspective view yof a Referring to the drawing, there is shown the upper portion 1 of an ordinary window frame having the usual sash guides or grooves 2 for the' upper and lower sashes, the upper cross bar or rail 3 of the outer or upper sash being illustrated in a slightly lowered position, all of which may be of any form of construction and needs no detailed description, the improved weather strip being applicable to all forms of window and door frames.

The weather strip, as shown in Fig. 5, comprises an angularly bent strip of thin metal, preferably of brass or some other equally resilient, non-corrodible metal, the angle thereof extending longitudinally throughoutits length, such length being the usual length of stock material of this class which is designed to be cut into the desired lengths to suit the particular frames to be supplied. j v

The longitudinal `angle 4 of the strip is located at one side of the center line of the same and provides a face or portion 5 and a face or portion 6, defining between the same an acute angle somewhat less than ninety degrees, and, designed to form attaching portions or bases to be alternatively used along the sides of a frame or at the top or bottom thereof for attaching the strip in position.

The faces or portions 5 and 6 extend different distances from the angle 4 land are each imperforate, the metal comprising the strip being thin enough to permit driving a nail or a tack therethrough` for holding the strip in place, although it is to be understood that the same may be formed of thicker and stouter material and provided with apertures for the passage of nails. tacks or screws. The face or portion 6 is of greater width than the face or portion 5.

The portion or face 6 is bent longitudinally of the strip inan inward direction at thereof during the upward and downward movement of the samel when raised or lowered, or to abut against the upper or lower rails of the sash when used at the bottom thereof or at the top as shown in Fig. 2 of the drawing. f

The strip as shown and described is used at the sides and top of the upper or outer sash and at the sides and bottom of the lower or inner sash, the saine strip being used though fastened in different ways. When attaching the strip at the sides of the window frame 1 to coact with the Stiles of the window sashes, the same is placed with the angle 4 thereof snugly fitting in the outer corner of the guide or groove 2 towards the out-side or front of the window frame` as shown in Figs.'3 and 4' of the drawing. and the fasteners 8 are driven through the face 6 thereof into the bottom wall of said channel 2. The free edge of the face 5` by reason of theacute angle between the faces 5 and 6, is in spaced relation to the outer wall of the said guide or groove, and bearing against the face of the sash, as shown `in Figs. 1 and 4 of the drawing, and the track 7 is also held in spaced relation to the bottom wall of the guide or groove and capable of cushioning action against the sides of the sash as the same is raisedor lowered. In this way, the same strip has a double bearing against the sash.

When the strip is applied as described, the resiliency of the face 5 of the strip serves to urge the sash against the adjacent face of the parting strip 9 of the window frame and the strip is thus flexed by the same, the Jfree edge of said face 5 springing'inwardly over the upper bar of the sash, when .the latter is lowered, and thus causing a tight joint at all times between the inner face of the sash and the inner wall of the guide or groove 2.

The strips for coaction with the sides of the sashes need only be applied to the opposite upper halves of the outer guides or grooves for use with the upper sash and in the lower halves of the inner guides lor grooves to be engaged with the sides f the lower sash. When the strips are applied for use in conjunction with the upper bar of the upper sash the plain faces 5 of said strips are used for fastening the same in position. said fasteners 8 being driven therethrough and into the inner face of the strip or bead forming the outer or front wall of the guide or groove at the top, as clearly shown in Fig. 1 of the drawing. rThis results in the face 6 and track 7 carried thereby being held in spaced relation to the bottom of the top guide or groove and in position to be struck by the top bar of the sash, when the .same is raised. ln like manner. thc strip may be attached to the sill of the window frame to be engaged by the bottom bar of the lower sash (not shown).

' From the foregoing, it will be seen that an extremely simple and cheaply manufactured weather strip for doors and windows has been provided which may be readily applied in proper position Without the necessity of removing the sashes from the frame, and that the same is adapted to reduce lthe friction in elevating or lowering the sashes by the provision of the tracks7 bearing against the side bars of the sashes, and that the space between the sash and frame is effectively closed against the entrance of cold air or water, etc., by reason of the cushioning eifect of the free edge of the face 5, which also prevents any rattling of the sashes by 'eect of winds, etc.

It will be seen that the strip provides a double joint along the sides of the sash by reason of the free edge of the face 5 bearin against the outer face of the stiles of sai sash, and the resilient tracks 7. bearing against the adjacent sides of the sash, and that the latter is held in perfect longitudinal alinement with the guides ready to be raised or lowered therein without any danger ofthe same wedging. It will be understood that the strips, when used in conjunction lwith a swinging door, are placed against the abutment faces of the frame in the same manner as at the top of the window frame, that is with the fasteners passing through the face 5 of the angle strip, so that the door` will strike against the face 6 and track 7. What is claimed is 1. A weather strip composed of a length of resilient metal bent longitudinally to provide faces or portions 0f different widths, the angle between the same being slightly less than ninety degrees, the face or portion of greater width having its free edge ortion bent further toward the portion o lesser width to provide a longitudinally disposed resilient track.

2. A weather strip composed of a length of resilient metal bent longitudinally to provide faces or portions of different widths, the angle between the same being less than ninety degrees, the face or ortion of greater Width havingy its free e ge portion bent further toward the portion of lesser width to provide a longitudinally disposed resilient track, and means for securing the face or portion of lesser width in the sash guide or groove of a window frame to cause the other face or portion with its track to bear against the sliding sash. 1
