March 27, 1962 H. K. LUNDGREN WINDOW SASH STOP Filed Feb. 25, 1960 3,026,580 WINDOW SASI-I STGP Herbert K. Lundgren, Oshkosh, Wis., assignor to Allmetal Weather-strip Company, a corporation of Illinois Filed Feb. 26, 1960, Ser. No. 11,283 6 Claims. (Cl. 2li-52) This invention is directed generally to window constructions and particularly to an improved installation carrying slidable, double hung window sashes. More especially, the invention is directed to novel means which provide the duel function of securing a sash guide and weather stripping element within a window frame and of limiting sliding movement of the sashes within their mounting frame.

Accordingly, the principal object of the invention is the provision of a new and improved window sash mounting construction. A further object of the invention is to provide a window sash stop and fastener element which provides for easier and more economical installation of the sash guide structure while, at the same time, providing a sash travel limit feature which prevents marring or damaging of the installation during use.

' Other objects and advantages of the invention will become apparent by reference .to the following description and accompanying drawings in which:

FIGURE 1 is a sectional view of a window installation incorporating the features of this invention;

FIGURE 2 is a fragmentary sectional view taken along line Z-Z of FIGURE 1;

FIGURE 3 is a fragmentary front View, partially broken away, illustrating a lower corner of the window mounting construction shown in FIGURE 1;

FIGURE 4 is an enlarged, fragmentary, partially broken away, view taken along line 4 4 of FIGURE l;

FIGURE 5 is an enlarged, fragmentary, partially broken away, sectional View taken along line 5 5 of FIGURE l; and

FIGURE 6 is an enlarged, perspective view of the novel stop-fastener element employed in the disclosed construction.

The window construction illustrated in the drawings incorporates the use of a novel element 11, which serves as a fastener and as a stop means so as to secure a combination sash guide and weather stripping element 13 within a window frame 15 and to limit travel of a pair of sashes 17 carried by the window frame.

The particular wooden window frame 15 shown in FIGURES l and 2 is typical of many constructions and incorporates an upright end member 19 extending between upper and lower transverse frame members 21 and 23. Of course, it should be understood that although the description concerns a vertically double hung installation, the advantages of the invention are readily realizable in a horizontally double hung installation.

`Fastened by a pair of the stop-fasteners 11 in overlying relation 4to the upright end member 19 is the combination sash guide and weather stripping element 13 which provides guide tracks for each of the pairs of window sashes 1'7. Except as otherwise indicated, the combination sash guide and weather stripping element 13 can be of any known construction. In the disclosed construction, the sash guide 13 includes a central parting stop of U-shaped formation and a pair of spring housings 27 which extend into mating vertical side recesses 29 in the window sashes 17, thereby also providing guidance for the travel thereof. Each of the window sashes 17 carries one of a pair of engageable lock members 31 and 33, the lock member 31 commonly carried on the lower sash being movable into the path of movement of the Patented Mar. 27, 1962 upper sash for locking interconnection with the member 33.

Considering the constructional features of the stopfastener element 11, which facilitates its dual employment to serve the purposes explained, the element 11 is formed of a strip of metal, such as steel, and includes a U-shaped end portion 35 which is slidably engageable over the end edges 37 of the combination sash guide and weather stripping element 13, and incorporates a spring clip feature to prevent accidental disconnection of the component 11 from the element 13 prior to installation in the frame 15, and to secure the stop-fastener relative to the sash guide 13. The other end of the stop-fastenerextends in the opposite direction from the open end of the U-shaped portion 35 and in partially adjacent, offset parallel relation thereto. This end 39 includes a pointed outer extremity 41 extending beyond the U-shaped portion 35 for impalement in one of the wooden transverse members 21 and 23. Connecting the pointed end part 39 and the U-shaped end portion 35 is a bent segment 43 having one leg 45 disposed generally perpendicular to the general disposition of the pointed end part 39 and U-shaped end portion 35 for location, in the finished installation, transversely across the path of sash movement to limit the travel of the sash in its guide track, and thereby prevent contact between the sash and the adjacent frame member. More particularly, the segment 43 is preferably rectangular in configuration, with the leg 44 disposed parallel to the leg 45 and joined therewith by a section 46 at right angles to the two legs. Although other shapes might be employed for the segment 43, the described arrangement is especially designed to withstand the forces ordinarily directed against the stop-fastener during its installation and use.

As most installations commonly utilize a sash guide and weather stripping element 13 extending the full height of the window frame, some provision should be incorporated for permitting engagement of the stopfastener 11 with the sash guide 13 to facilitate initial assembly therebetween, so that the pointed extremity 41 of the component does not initially extend beyond the end edges 37 of the sash guide and weather stripping element and, therefore, does not interfere with the placement of the sash guide and Weather stripping element 13 against the end frame member 19. In the disclosed construction, this feature is provided by cut-outs 51 in the opposed sides and at opposite ends of the parting stop 25, which cut-outs 51 extend for at least approximately the length of the pointed extremity 41 which projects beyond the U-shaped portion 35. Of course, the cut-outs 51 are not as long as the U-shaped portion itself.

During erection of the window mounting construction, one of the stop-fastener elements 11 is slidably engaged with the combination sash guide and weather stripping element 13 at each end on opposed sides of the parting stop 25 and extends within the cut-outs 51 formed therein. As pointed out previously, this engagement includes a degree of over-travel required to prevent projection of the pointed extremity i1 beyond the adjacent end edge 37 of the sash guide 13. The guide 13 is then laid yflush against the end frame member 19, and the pointed extremities 41 of the stop-fasteners 11 are driven into the wooden top and bottom transverse members 21 and 23, respectively, thereby securing the combination sash guide and weather stripping element in lixed relation to the end frame member. When thus installed, the leg 45 of the bent segment 43 extend in the path of sash travel to prevent striking of the upper frame member 21 by the lock member 31 incident to excessive upward movement of the lower sash. In addition, the stop-fastener at the lower end of the combination sash guide and weather stripping element will limit downward movement of the upper sash, so that the upper cross bar 53 thereof cannot be lowered to a position of possible damaging interference with the lock member 3l which, when the inner sash is fully lowered, may be unintentionally located in the path of travel of the upper sash. Thus, the disclosed stop-fastener functions eifectively both to easily secure the combination sash guide and weather stripping element in position on the end frame member and to limit travel of the window sashes to preclude damage to the sashes and the mounting frame structure.

Although shown and described with respect to a particular construction, it will be apparent that various modifications might be made without departing from the principles of this invention. For example, the stop-fastener element might be of a different configuration and still serve its intended purpose, and it might be positioned elsewhere than described with respect to the sash guide i3.
