Blair, New York, N. Y. Application March 29, 1935, Serial No. 13,622 5 Claims. (Cl. 292-76) i-Thiislinven-tion relates to devices for use in con nectionfwi-th window sashes and’ more particularly to'sash-holding devices. ' ()ne of the objects of this invention is to pro vide a device of the above character which will be simple,‘ practical and thoroughly durable. Another object is to provide a device of the above character which may be easily installed by un skilled ‘labor. Another object is to provide a practical device of the above character which will prevent rattling of the sash in- the frame While still permitting the sash to be easily moved. Another object is to- provide a device of the above 1, 1 systems has been installed, it usually performs only this one function of forming a means for adjusting the position of a member within a frame and neither prevents rattling, which is usually found in all such systems, nor does it serve as a weather stripping in such a case as when a sash is mounted in a window frame. Among the sev eral objects of this invention are to provide de~ obvious and in part’poin-ted out hereinafter. - The» invention accordingly consists in the fea tures of construction, combinations of elements, and arrangements of parts as will be exempli?ed in the structure to be hereinafter described and ' the’scope of the application of which will be indicated ' the following claims. the accompanying drawings in which are shown several of the various possible embodi ments of‘m'y invention, ' Figure‘ l is‘ an elevational view of a window with certain of the parts broken away having the device installed therein ;' ' ' Figure 21 is a perspective View of a part of a window having the device installed therein; ca "01 the ordinary layman to repair. Furthermore, the installation of eounterbalances usually re quires the services of skilled labor adding to the cost of performing the job. When one of these character which will‘ form an effective weather vided‘ev-ices of the above character of simple and inexpensive construction and efficient and de pendable action. Other objects will be in part Elf! cumbersome. Furthermore, the counterbalances must be positioned in a place which is not easily accessible and where it would not be easy for strips'to preventthe atmosphere entering around the edges of the sash... Other objects are to pro~ Figure 3' is a sectional View taken along line 3—3 of Figure 1; ' Figures 4 and 5‘ are sectional views similar to Figure 31 having modi?cations of my device in of wood or the like although a metal frame may be used‘. Window frame It may be constructed in the usual manner having a pair of stiles l I, a top portion l2, and a sill 43 all of which are secured together by any suitable means such as by screws or nails. Preferably near the center of stiles H and secured thereto I have placed guide strips it. Guidestrips Hi preferably extend from the top portion l2 to the sill l3 and have their sides 95 and I7 (Figure 3) perpendicular to the stiles H. Secured to the outer edges l5 of the stiles l i and extending inwardly toward the center of the frame l0 beyond the inner surface 29 of the stile I! are cover boards IS. The sides I!) (Figure 3) of the cover boards iii are preferably parallel to stalled therein; Figure 6- is a plan view of the modi?cation in Figure 5 with certain of the parts broken away; on opposite sides of the frame l5) within which sash 2! may slide, its movement in one direction Figure '7 is a perspective view of a modi?cation being limited by the top portion l2 and in the opposite direction by the sill l3. Between the sides 22 of the sash 2i and the ' Figure 8‘ is a side plan view of the modi?cation ~ in Figure 6. surface 29* of the stiles H there is a space 23 ‘Similar reference characters refer to similar parts throughout the several views of the draw ings'. is vices and methods for overcoming the above— mentioned difficulties. Referring now to the drawings in detail, there is shown in Figure l a window frame generally as indicate-cl- at it which is preferably constructed the sides IE of the guide strips It and thus guide strips l4, stiles I l and cover boards l8 form tracks of my. device; and - M weight of the member and, of necessity, are f ‘As conducive to a clearer understanding of certain features of this invention, it might here be pointed out that previous methods for holding a member at any desired position upon a track within a frame have been accompanied by ex— cessive cost and ineffectiveness of result. Many of these devices use weights to counterbalance the (Figure 3) which extends for the length of the side 22 of the sash 2i and is rectangular in cross section. The width of this rectangle preferably is a great deal smaller than the length which is the width of the stile H between the side l5 of 50 the guide strip Ill and the side iii of the cover board if! such as is usually found in constructions of this type. I Within this space‘ 23 and preferably extending longitudinally between the top portion l2 and the 2,122,553 2 , sill l3 and in the track within which the sash 2| slides, I place a resilient strip 24 preferably constructed of metal such as stainless steel. Preferably this strip is concave in cross section having its convex side toward the side 22 of the sash 2| and between its two edges 25 and 26 hav ing less length in crosssection than the space between the guide strip H and the cover board I8. Preferably the width in cross section of 10 this strip when positioned upon the stile II is sufficiently greater than the width of the cross section of the space 23 so that the strip 24 will be compressed by the sash side 22 against the stile H and exert a resilient force against the‘ 15 side of the sash. Preferably, the inner edge 25 of strip 24 is turned upwardly away from the stile to form a lip 21!. This prevents friction between this edge of the strip and the stile when the strip is com 20 pressed by the side 22. The opposite edge 26 of the strip 24 is preferably secured to the stile by any suitable means, as by a wedge shaped nail 28. If this type of nail is used and the strip is not punched for the nails, the edges |'| im 25 mediately surrounding the nail as it is driven through the metal will be bent inwardly (Figure 3) and into the stile forming a very secure con nection. These nails 28 would be driven through the strip 24 at suitable intervals (Figure 2) to 30 hold the edge of the strip securely against the stile. Thus, I have provided a resilient strip pref erably concave and constructed of resilient sheet metal capable of being attached to the stile H of a window frame and lying in the track in 35 which the sash 2i slides. Also this strip 24 is su?ciently concave as to be compressed by the side of the sash 2| when it is in position thus ex erting a resilient force against the side 22 of sash 2| holding the sash in any desired position upon the tracks in the frame. , Immediately below the edge of sides 22 the compressing force exerted by the sash 2| upon the resilient strip will be released and the strip will resiliently stand out forming stops 29. These 45 stops 28 will always be immediately below the lower edges of the sides 22 wherever the sash 2| may be placed within the frame I0 and there fore will form a second means for holding the window in any desired position within the frame. The strips 24 which I have thus placed be 50 tween the sides of the sash 2| and the stile II also form a very effective weather stripping. As the strip is attached to the stile II, a tight con nection will be formed between the two, and 55 when the strip 24 is compressed by the sash 2| the strip will exert a constant resilient force both against the stile H and the side of the sash 22, effectively sealing this aperture which ordi narily exists between the sides of the usual sash 60 and stile construction. Also because of the con stant resilient force exerted by the resilient strip against the side 22 of the sash, the sash will be prevented from rattling or vibration as the re silient force will counteract any movement of 65 the sash caused by the wind or vibration. Thus, this resilient strip 24 which is prefer ably concave but may take any other desirable shape not only serves as an effective stop for the sash but also serves both as weather strip 70 ping and as an anti-rattler. Referring now to Figure Zl, one of the many possible modi?cations of the strip 24 is shown attached to stile | | and exerting pressure against the side 22 of the sash 2| which is compressing 75 it. This type preferably consists of two parts 30 and 3| concave in cross section connected by a convex portion 32 all of these surfaces preferably being pressed from one resilient metal strip. This forms two surfaces pressing against the side 22 of the sash 2| and leaves a portion 32 5 which may be securely attached to the stile by nails 28 or by any other suitable means. A second modi?cation is shown in cross sec tion in Figure 5 a channel 33 having been cut into the edge 22 of the sash 2| and a concave metal 10 strip 24 having an upturned lip 2'! is secured in this channel so that the concave surface of the strip 24 faces the sash and the convex sur face abuts against and is compressed 'by the stile II when the sash is in position against the 15 stile. To prevent the upper and lower edges 39 of the concave strip 24 from digging’ into or forming undue friction with the stile II as the sash 2| slides in its track, I preferably secure the ends of the strip to the ends or sides of the 20 stile. In Figure 6, I have shown the edges 39 of the strip 24 secured to the side of thevsash at 41! and secured to the end of the sash at 4|. The edges are secured by any suitable means such as by nails 42. 25 Referring now to Figure '7, I have shown a series of cut-out portions 34 in the side 26 of the strip which is to be secured to the surface on which the strip is to rest. These cut-out por tions, which are preferably in the shape of tri 30 angles, are cut through strip 24 only on two edges 35 and 36 and then bent downwardly using the third edge 31 as an axis to form a series of pointed lugs 38 (Figure 8) preferably perpen dicular tothe plane drawn between the edges 26 35 and 27 of the concave strip 24. These lugs will form an e?icient means for attaching the strip 24 to any surface. Thus, I have provided two , modi?cations for placing and shaping the strip each of which will perform the unique function 40 of acting as a stop for a sash in a window frame, an effective weather strip, and an anti-rattler. And I have also provided an e?icient and in-, expensive means for attaching the strip to a surface. 45 It will now become clear that with my unique and simple device and method, I am able to per form three de?nite functions in holding a sliding member at any desired position within its track, sealing the aperture between the sliding mem 50 her and its track, and preventing excessive lateral movement of the member as would cause rattling of the member within its tracks. It is to be understood that each of these functions is of independent value and the construction may 55 'be arranged to accomplish anyone or more of them as an embodiment of features of the in vention. Furthermore, it will be noted that this has been accomplished in a simple and efficient manner by a device which may be manufactured 60 at extremely low cost. All of the factors accom plished by this device offer material advantages in the production of this device and to the user. It will thus beseen that I have provided a thoroughly practical device for holding a sliding member within its frame at any desired position in which the several objects hereinabove men tioned as well as many others are successfully accomplished. As many possible embodiments may be made of the above invention and as many changes might be made in the embodiment above set forth, it is to be understood that all matter here inbefore set forth, or shown in the accompany 75 3 2,122,553 ing drawings, is to be interpreted as illustrative and not in a limiting sense. I claim: 1. In a construction of the nature described, comprising a sash member and a stile member along which said sash slides, in combination, a transversely resilient metallic strip interposed between said members and shaped to be yield ingly compressed thereby, and securing devices 10 extending along said strip to hold the same against one of said members, said devices having tapering head portions contacting and holding portions of the strip into the member which they enter, whereby said strip may be substan 15 tially ?attened against the member to which it is secured. 2.
