Serial No. 322,28.

7 This invention relates to an improved Weatherstrip particularly adapted for use in connection with metal sash.

A primary object of the invention is to provide a novel metal Weatherstrip to be used on sliding sash. While metal weatherstrips have been heretofore employed in connection with the, easement type sash, nevertheless,

strips intended for that purpose are not conveniently adaptable to sliding sash. 'In that connection, the invention contemplates the provision of a simple and practical form of self-securing Weatherstrip which may be readily fitted to the part of. the sliding sashv which fits in the window. frame, and not only prov des a weather-proof joint, but at the same time takes up the play between the sash and the guideway in the frame to prevent rattling of the sash while at the same time permitting it to slide freely under all condit ons of use., 1

A further object of the invention is to provide a "metal Weatherstrip for sliding'sash of a metal sash and window frame having-the which is provided with means for assisting 111 the guiding of the sash during its sliding -movement. That is to say,'it is proposed to provide a portionof' the strip 'witha part which parallels the guideway in the window frame so that as the sash is moved up and down the said part will act to limit.the side of the inyentioniswbet'ter understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described illustrated and claimed. T

A preferred and practical embodiment of the invention is shown in the accompanying drawings, in which':.

Figure 1 is a detail elevation of a portion present invention applied thereto. I

Fig. 2 is a horizotal cross-sectional view taken on the line 22,of Fig. 1. I

- Fig. 3 is a detail perspectiveview of the improved Weatherstrip.

Similar reference characters designate corresponding parts throughout the several figures of the drawings.

According to the embodiment of the invention shown .in the drawings, the present Weatherstrip includesa body designated genthe loop or rib 4. This rib constitutes one of the distinctive features of the invention, and is of special importance in a strip for sliding sash since it acts as a stop or abutment for limiting the side movement of the sash when it is raised and lowered in the window frame.

As will be observed from Fig. 2 of the drawings, the strip is applied to the frame F of the sash by fitting the yielding securing portion B over the portion of the frame which projects through the guideway G in the window frame Wwhile the body portion A snug- As will be observed from 3, the securwith the bodyis increased by the provision of I ly'fits the outer face of the sash frame and v the loop which forms the rib 4 is posiitoned substantially in the angle formed between the sash frame and the window frame thereby to act as a stop and prevent undue side motion of the sash during its movement. The weather-flange 3 is compressed in the space between the guideway and the body A of the strip thereby to close the gap and keep out air, thus making a tight fit between the outer side of the sash in the window frame, and without exposing the strip'to view-from the inside of the Window. As previously indicated the resilient weather-flange C also prevents the rattling of the window since it yieldingly presses the frame F against one side of the guide at all times. Thus, the sash is not only steadied and balanced in' its sliding movement by the yielding flange 3' and the rib ,1 but a practical weather-proof joint is water at the sides of the window but also acts as a part of the guiding means for the sash.

Another feature of the invention resides in the relationship of the ribl to the securing portion B when the same is applied to the sash. As will be observed from Fig. 2 the securing-or clip portion B is fitted overthe. edge of the frame F in one direction while the ribbeing on the otherside of the window frame which forms a part of the guide, acts as a lock for preventing the disengagement of the securing or clip portion B from the edge'of the window frame. Thus, it is impossible for the strip to accidentally become displaced from the edge of the sash afterit has een once applied.

Without further description it is thought that the features and advantages of the 'inven tion will be readily apparent tov those skilled in the art, and it will of course be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention and scope of the appended claims.

I claim 1. A Weatherstrip for sliding metal sash comprising in'combination with a guideway for the sash, of a metal strip doubled upon itself to provide a sash embracing portion and a guideway engaging portion, said guideway engaging portion including a rib for limiting the side movement of the sash.

2. In a Weatherstrip for sliding sash, the combination with the window framehavinga guideway and a sash' member slidable therein,

" of a Weatherstrip havin mean for engaging the sash and a resilient ange portion having means for closing the guideway and also having means for limiting the side movement of the sash.

3. In a Weatherstrip for: sliding metal sash, the combination with the window frame having a guideway for the sash, of a re;

silient strip having a channel portion at one edge for engaging with the sash and an out turned resilient weather-flange for engaging with one side of the guideway, and a rib formed on said flange for limiting the 5. In a Weatherstrip for sliding sash the combination with the window frame having a guideway and a sash member slidable therein, of a Weatherstrip having means for engaging the sash and a resilient flange portion extending between the sash and the Window frame and having means for limiting the side movement of the sash.

6. In combination, a slotted sash frame, a sash stile slidably engaged in the slot in said sash frame, a weatherstri mounted on said sash stile Within the sash fr tending through said slot exteriorly of the sash frame, said Weatherstrip having a bead formation outside the sash frame for cooperation with the sash frame to limit, inward lateral movement of the sash relative to the sash frame,'sa id bead formation having a bead remote from the sash frame.

7 In combination, a slotted sash frame, a

ame and ex sash stile slidably engaged in the slot in said sash frame, a Weatherstrip mounted on said 1 sash stile within the sash frame and extending through said slot exteriorly of the sash frame, a bead formed along one sideof said strip outside the sash frame for cooperation with the frame to limit inward lateral movement of the sash relative to the sash frame,

said bead having a free edge portion disposed at the side of the bead remote from the sashframe, and-a stiffening flange at the free edge portion of said bead.

In testimony whereof I hereunto aflix my signature. 7 1
