"- that they did not allow for any irregularity in the dimensions of the window frame and sashes and while they operated satisfactorily if the parts of the window were perfectly true they would not operate to form a weather tight engagement between the wlndow frame and sashes if there was shrinkage or if for any other reason the parts of the Window became untrue.

Some of these deficiencies were obviated by the construction described and claimed in my previously issued Patent No. 1,511,460 of October 14, 1924, but the construction shown therein was expensive to manufacture and install and was not adaptable for all types of windows.

Therefore, the objects of this invention are to provide a Weatherstrip structure for forming a weathertight joint between a sliding sash and the window frame in which it is mounted, which structure will be cheap to manufacture and install; to provide such a Weatherstrip structure which will operate as efficiently upon Windows which are untrue due to shrinkage or other causes as upon windows which are true; and to provide such a Weatherstrip structure which is identified with the parting strip of the window but is separate therefrom.

lVith these and other objects in mind several embodiments of my invention are fully shown in the accompanying drawings where in similar characters are used to designate similar parts: Fig. 1 is a transverse sectional View of a fragment of a window near the top thereof upon which one form of my weatherstrip structure has been applied and with the two sashes thereof in a position where they are side by side; Fig. 2 shows diagrammatically the parts of theweatherstrip structure shown in Fig. 1; Fig. 3 is a vertical sectional View of a fragment at the sill and bottom of a window; Figs. 4, 5 and 6 show details of construction of this form; Fig. 7 is a transverse sectional View as in Fig. 1 of a modified form of Weatherstrip structure embodying my invention; Fig. 8 shows diagrammatically the parts of the Weatherstrip structure shown in Fig. 7; Fig. 9 is a vertical sectional view of a fragment of a window; and Fig. 10 shows a detail of this modified form.

Referring to the figures and particularly to Figs. 1 to 7. inclusive, the window upon which my new and improved Weatherstrip structure is applied has a frame 1 in which a pair of sliding sashes 2 are mounted. The frame 1 has a groove 3 therein and the sashes 2, preferably, have the inner edges of the stiles rabbeted as at 4:, all for the purposes more fully hereinafter set forth. My new and inrproved Weatherstrip structure as shown herein includes a member 5 on the frame and members 6 on the sashes. The member 5 on the window frame comprises a base port-ion 7 which follows the contour of the groove 8 in the frame and is itself formed and adapted to provide a groove to receive the parting strip 8 so that the base portion 7 extends alon but is separate from the parting strip 8. This parting strip is preferably of metal as shown in the figures as I have found that such a strip will last longer in use, but as set forth below I do not limit myself to any material. The member 5 also comprises a pair of Weatherstrip members which in this embodiment are ribs 9 each of which projects outwardly from the side face of the parting strip 8, as shown. Each of the members 6 carried by a sash has a channel portion 10 which, preferably, follows the contour of a rib 9 so that a sliding weathertight engagement is formed therewith. If any other form of Weatherstrip portion is used the portion 10 is changed to form a sliding weathertight engagement therewith.

I prefer that some resilient means such as springs 11 be set between the bottom of the groove 3 in the frame 1 and that part of the base portion 7 of the member 5 which forms the bottom wall of the groove to receive the parting strip 8, for the purpose more fully outlined below. Each of the springs 11 may be held in position by inserting an end thereof through a slot 18 in the rear wall of the base portion 7 of the member 5, as shown in Fig. 3.

In assembling my Weatherstrip structure the Weatherstrip member 5 and the springs 11 carried thereby, as described above, are placed in the groove 3 and the parting strip 8 is then placed in the groove in the base portion 7 provided to receive it. It will be seen that the parting strip 8 will maintain the member 5 in the desired position and I prefer that the parting strip 8 be held in place by a screw 13 or other means passing therethrough and passing through the bottom wall of the base portion 7 of the member 5 into the frame 1 and I also prefer that only one such supporting means be used and that it be placed near the upper end of the parting strip and Weatherstrip member 5. The lower end of the parting strip may be held in position by a clip 14 fastened to the bottom of the frame and I prefer that the clip 14 is slotted at 15 so that the position of the lower end of the parting strip may be adjusted. The weatherstrip members 6 are fastened onto the sash preferably by brads 16 with the channel portion 10 positioned in the rabbets l. The sashes are then placed 'a the window so that a sliding engagement is made between the ribs 9 and the channel portions 10. The ribs 9 need not extend from top to bottom of the window or both sides of the parting strip, although I prefer that they do, because it only is necessary that each rib is as long as the sash carrying the channel portion 10 in engagement therewith so that a weathertight joint will be formed when the sash is in closed position.

If the parting strip and, in turn, the Weatherstrip member 5 are supported in this manner and if the screw 13 is not turned down tight, but leaves a play between the bottom of the member 5 and the bottom of the groove 3 the parting strip 8 and the Weatherstrip member 5 will be mounted in what may be termed a floating position and when installed on a window will be moved slightly inwardly toward the window frame 1 and the springs 11 will be compressed. If the parts of the window shrink or swell to allow a greater space between the window frame and the sashes the parts of the weatherstrip structure and the parting strip 8 will quickly adjust themselves to any irregularity in the parts of the window.

In the embodiment of my invention shown in Figs. 7 to 10, inclusive, the Weatherstrip member 5 carried by the window frame has the base portion thereof formed in two parts with the overlapping edges 7 a and 7 forming the bottom wall of the groove to receive the parting strip. This form of Weatherstrip is particularly adapted for use on windows having parting strips or grooves which are not of standard dimensions because as may be readily seen the member 5 can be adjusted to various widths of parting strips or grooves without necessitating a different member for each width.

It should be noted that in this embodiment of my invention it is necessary to provide notches 17 extending inwardly from the side of the overlapping edges 7 and 7 to receive the supporting screw 13. Likewise, this embodiment of my invention may be quickly and easily applied to windows and when so applied it is not necessary to provide a special parting strip 8, but the old wooden parting strip 8 may be replaced because the member 5 may be adjusted. to the width of the old strip. When a wooden parting strip is used the springs 11 may be reversed and held in place by a small nail or screw 19 passing through the hole 12 in the spring into he parting strip.

It may be readily understood that I do not wish to limit myself to the exact details of construction shown in the drawings because the size, shape and arrangement of the various parts and especially the arrangement of the portions which form sliding engage ment between the Weatherstrip members 5 and 6 may be varied within wide limits without deviating from the spirit of my invention as included in the claims set forth below.
