6 Claims.

a weather-strip which will eliminate noise and rattle of the window sash during high winds; is quickly and easily installed, and which may be cheaply manufactured.

With the above and other objects in View, as will hereinafter appear, the invention comprises the devices, combinations, and arrangements of parts hereinafter set forth and illustrated in the accompanying drawing of a preferred embodiment of the invention, from which the several features of the invention and the advantages attained thereby will be readily understood by those skilled in the art.

Figure 1 is a perspective view of a portion of a window frame and double sliding sash showing our improved weather-strip applied thereto.

Figure 2 is a sectional view of a portion of a window frame and sliding sash with our improved weather-strip applied thereto, the view being taken through the upper sash, and the lower sash being shown in top plan.

Figure 3 is a section taken through the weather-strip.

Figure 4 is a perspective view of the weatherstrip.

In the embodiment of this invention selected for illustration, our improved weather-strip comprises a metallic parting head or casing A having a bottom wall l (Figure 3), a side wall 2, a top wall 3, and a depending wall 4. This casing is substantially C-shaped in cross-section and may be formed by a continuous process in indefinite lengths.

Located inside the casing are spaced tubes 5 which register with the holes 6 and 1 formed in the bottom and top walls I and 3. The metal around these holes is forced into the ends of the tubes to securely hold them in their correct position.

Received within the casing is' a member B, of substantially S-shaped cross-section, the walls 8 and 9 of which, have sliding contact with the walls 2 and 4 of the casing. The wall [0 is apertured to receive the tubes 5 and is slidable thereon. Coiled compression springs ll surround the tubes 5 and each spring has one of its ends reacting against the walll of the casing A and its other end against the wall lll of the member B. It will be obvious from the above that the member B is slidable in the casing A and is held in position and guided in a right line movement therein by the contact between the walls-2 and 8 and the walls 4 and '9. It will also; be

obvious that the compression spring [I constantly urges the wall l0 towards the wall 3;-

Our improved weather-strip is applied to windows in the following manner; the usual longitudinal groove I4 is cut in the upper sash l4 and the parting-bead is removed from the groove I5 in the board l6 of the frame and a length of the weather-strip equal to the height of the upper sash, is placed in the groove I5, in such a position that the tongue or flange ll of the member B enters the groove M in the sash. A groove I8 is cut in the lower sash l9 and a length of weather-strip equal to the height of the lower sash is placed in the groove I5 in ,a position so that the flange ll of the member B enters the groove I8. The weather-strip is held in position in the groove l5 by means of wood screws 20, and, 'of course, the weather-strip is applied to both sides of the sash.

From the above it will be understood that the wall 2| of the member B is at all times spring urged into contact with the edge of the window sash to prevent the passage of air therebetween and that the sash may swell, due to the absorption of moisture, without effectingtheir relationship. It will also be understood that dueto this arrangement, the sash is resiliently held at all times, thereby eliminating noise caused by the movement of the sash during high winds. Further, the sash engages and is held in position by the wall 4 of the casing A, the tongue I! and the wall 2| of the member B; therefore the sashes do not come in contact with the window frame with the result that the sashes slide on smooth metal only. This feature permits clearance at the edges of the sash and when the window frames are painted the windows will not stick.

From the foregoing description considered in connection with the accompanying drawing, the construction and several advantages of our improved Weather-strip will be clearly and fully understood. It is apparent that the weather-strip may be used for the easement type windows, and it will be understood that the form, construction and arrangement of the elements may top and bottom walls, a member carried by and slidably engaging said sidewalls, said member being formed with a weather-strip flange, and

spring means for urging said member towards 1 and side walls and adapted to be used as a partthe top wall of said member. v

2. In a window having a frame and a sas slidable therein formed with a longitudinal groove, the combination of a metallic partingbead of substantially C-shape in cross section secured in said frame, a substantially -S-shaped,

tion of a metallic parting-bead of substantially C- shaped cross-section, a plurality of tubes carried by said parting-bead, a substantially S-shaped metallic weather-strip having one portion movably supported 'in said parting-bead and slidable along said tubes and another portion projecting into a groove in said sash, means normally urging said weather-strip into said groove, and means extending through said tubes for securing said parting-bead in place insaid frame.

5. A weather-strip comprising a substantially reptangularly shaped hollow casing having top ing-bead in a window frame, an S-shaped member slidable in' and extending from one side of said casing; said member having two of its limbs engaging the side Walls of said casing, and resilient means for constantly urging said slidable member against one of'the walls of said casing.

- GKAWather-strip for windows comprising a vhollow casing adapted for use as a parting-bead and having side and top walls, onelof said-side 7 alls being formed/with an'. opening, a imember slidable in and having .a portion extending laterally fromthe casing through 'saidfopenihg, saidportion. having aben't overed'ge which is adapted to enter a groove in a window sash, and spring means for urging said member towards the top wall of said casing.
