Claims.
This invention relates to windows and more particularly to sliding windows or windows of the double hung type.
It is an important object of the invention to <sub>5</sub> provide a thoroughly weather-proof, double hung window which is of rigid construction, which can be made inexpensively and in which all of the sash engaging frame members are formed of noncorroding non-ferrous metal.
It is a further important object of the invention to provide such windows with a sealing construction incorporated as an integral part of the window which will cause the window to be firmly and completely sealed and which will prevent rat25 tling but which will at the same time provide perfect freedom of movement for the sashes and permit wide tolerances in the dimensions of the parts.
To this end it is a feature of the invention that <sub>20</sub> a sash engaging and guiding construction is provided having a plurality of independently flexible continuous spring surfaces disposed angularly to one another and adapted to engage respectively a face and an edge of the sash. With such an <sub>2g</sub> arrangement the edge engaging spring members at opposite sides of a sash bear in opposed relation against the opposite edges of the sash and balance one another. Each is free to yield, however, and each forms a firm sealing contact with 30 the engaged edge of the sash. The face engaging spring members may urge the sash toward a parting strip. Each of these members also forms a firm sealing contact with the engaged portion of the sash so that along each sash stile and along 35 the top rail of the upper sash sealing is effected independently at successive points. At the same time the pressure against the sash is so light and of such yielding nature that all tendency toward binding or frictional resistance to the movement <sub>40</sub> of the sash is substantially avoided.
It is a further feature of the invention that the spring members are so constructed and housed that the edges thereof are covered and guarded to prevent liability of a person’s being cut by the edges.
In accordance with a further feature of the invention the sash lifts provided on the bottom rail of the lower sash are provided with cam extensions engageable with wedging members pro50 Vided on the sill, for reinforcing the bottom rail of the lower sash when the sash is in closed position.
In accordance with a further feature of the invention the sill is provided with an outwardly 55 and downwardly extending lip for interfering (Cl. 189—65) with the ingress of rain or snow and the bottom rail of the lower sash is provided with a downwardly extending flange or lip which is drawn into firm engagement with the outer face of the sill lip when the window is closed. The co-act- <sub>5 </sub>ing cam members on the sill and sash serve to draw the sill and sash lips into firm contact with one another.
Windows embodying the invention may be made entirely of non-ferrous or non-corrosive χθ metal or partly of wood covered by non-ferrous metal, or partly of steel covered by non-ferrous metal. It is a feature, however, that any ferrous metal which may be employed is covered and protected by non-corroding metal, and that all parts 15 having rubbing contact are composed of nonferrous or non-corrosive metal.
Other objects and advantages will hereinafter appear.

Figs. 6 and 7 are further views similar to Figs. 1 and 2, respectively which illustrate a further form of window embodying features of the invention, and; <sub>4g</sub>
Fig. 8 is a view in elevation showing the rigid buck employed in the window of Figs. 6 and 7.
The window of Fig. 1 is shown as mounted in a wall I. The building structure may include the usual wooden jamb, header and subsill, and 50 wooden retaining or moulding strips 3 along the top and sides of the window opening. The window frame comprises a metallic sill member 4, metallic uprights or jambs 5 and a metallic head 6. The frame is adapted to be used with either 55
2,084,776 wooden or metal sashes but it is preferably used with a metal window having an upper sash 7 and a lower sash 8 of the construction illustrated.
The sill member 4 may be an extruded mem5 ber of aluminum, brass, bronze or other noncorroding metal. The same materials may be used in the other exposed metallic members of the frame and window. The sill member 4 comprises a sill flange 9 which overlies the wooden 10 sill 2 and which is secured to the wooden sill by means of screws 99. The sill member 4 further includes a weather strip housing comprising a side wall H and upper and lower walls 12 and 93. The upper wall 92 is provided at its outer 15 edge with a downwardly extending lip or flange 14, and a lip or flange 95 extends upward from the bottom wall 13 for a short distance. A weather strip 96 of spring metal is enclosed in the space bounded by the walls 11,12 and 13 and <sup>20</sup> the lips 14 and 95. The weather strip comprises a base web 97, a vertical web 98 and a sash engaging web 19 which is exposed to contact with the lower inner edge of the lower sash through the space between the lips (4 and 15.
<sup>20</sup> A lip or flange 20 is extended outward from the lip 15 and then downward to provide an overhanging portion adapted to be seated in a recess at the inner lower portion of the lower sash for interfering with ingress of rain or <sup>υ</sup> snow.
The sill member 4 has a portion 21 which extends downward in the plane of the lip 15 and a portion. 22 which slopes downward and outward to the outer boundary of the sill base. At the outer extremity of the base portion 22 the sill 4 has portions 23, 24 and 25 which extend downward, outward, and downward, respectively. The portions 23 and 24 form a seat for the lower <sub>4</sub>θ end of a screen 26 and the portion 25 forms a web for forming a weather tight joint with the wall structure of the building.
The two jambs 5 are of like construction and each comprises a vertical strip 27 of sheet metal <sub>45</sub> having a vertically extending channel 28 formed centrally therein and screw holes formed in its margins. The channel 28 serves to locate a parting strip 29 and the screw holes serve to locate retaining beads 30 and 31. The edges of strip <sub>50</sub> 27 are protected and held by moulding beads 3.
The parting strip 29 is preferably a drawn or bent sheet metal member with a wooden core, or it may be an extruded metal member of hollow construction, formed with outwardly facing <sub>55</sub> shoulders 32. The parting strip is secured to the wood frame by means of screws 33 which are passed through the parting strip and threaded into the wood frame. The inner retaining bead 30 comprises a web 34 which is secured to the <sub>60</sub> frame by screws 35, an inwardly extending web 36, and a reverse lip or flange 37 provided at the inner extremity of the web 36. The retaining bead 30 and the parting strip 29. co-operate to form a guide and housing for one side rail of 65 the lower sash. They further co-operate to house a flexible sealing and guiding member 38 which co-operates with the lower sash.
This member 38 is of novel construction and constitutes a very important feature of the 70 present invention. In its preferred form it comprises a free, resilient web 39 for bearing against the outer surface of the sash, a vertex portion 40 which is received between and imprisoned by the web 36 and the lip 37 of the retaining bead 75 30, angularly related positioning webs 49 and for engaging respectively the web 36 of the retaining bead 30 and the plate or strip 27, and a free spring web 43 for engaging an edge portion of the lower sash. The end of the web 43 extends beneath the shoulder 32 of the parting 5 strip and plays in the space between the shoulder and the metallic sheet 27, the edge of the web being guarded by the parting strip shoulder. The edge of the web 39 plays in a recess of the sealing member and is guarded by a <sup>10 </sup>shoulder bounding the recess.
It will be seen that the web 39 urges the sash into firm contact with the parting strip, thus causing the sash to move in a straight path and in sealed engagement with the parting strip. <sup>15 </sup>The web 43 bears against the edge of the sash and forms a second line or area of sealed engagement. The web 39 bears against the inner surface of the sash and forms a third line or area of sealed engagement. The webs 39 and 43 <sup>20 </sup>are free to flex independently of one another. The sash is supported between the webs 43 at opposite sides of the frame and since either of these webs is free to yield, the sash may shift <sub>25 </sub>from side to side as resistance is encountered. There is no possibility, therefore, of binding resulting from too fine a clearance of the assembled parts. Similarly the webs 39 afford considerable play for the sash so that the re- <sub>3</sub>θ taining strip 30 can be set far enough away from the parting strip to afford easy clearance for the sash. There is no possibility of rattling, however, because the weather strips always bear firmly against the sash and cushion it. The 35 spring members can be separate pieces as well as one piece; and shape and arrangement can ‘ be varied.
The outer retaining bead 3 9 is similar to the inner bead 30. It differs, however, in that it comprises an outer web 44 for engaging an outer face of the wood frame structure. It also comprises angularly related webs 45 and 46 which form a seat for the screen 26 and an inwardly extending web 47 which terminates in a flange <sub>45 </sub>or lip 48. A wooden filler strip 49 is desirably set into the retaining bead 31, a sealing and guiding member 50 similar in all respects to the member 38 which has been described is housed between the flange 48, the block 49 and the plate 50 27. The outer retaining bead 31 is secured to the wood frame by means of screws 51 which pass through the web 47, the wooden strip 49, and the plate 27 into the wood frame. The member 50 co-operates with the upper sash in 55 the same way that the member 38 co-operates with the lower sash.
The head construction is similar to the jamb construction. The head construction comprises a fnetallic plate 52, a parting strip 53 and an 60 outer retaining bead 54. Between the parting strip 53 and the outer retaining bead 54 there is housed a sealing member 55 preferably similar to the member 38 which has been described.
Counterweights may be employed, but prefer- 65 ably the sashes are counterbalanced by spring drums 55α whose movable elements are connected to the sashes through flexible bands 55b.
The preferred form of sash structure is illustrated in Figure 1. The upper sash 7 is composed 7G of tubular metallic rails formed with inwardly extending flanges 56 for forming a seat for a pane 57, and metallic angle bars 58 or any other suitable retaining means may be employed at the opposite side of the pane. The meeting rail of the 75
2,084,776 3 upper sash carries a sealing member 59 which may be an extruded metallic member. The member 59 extends across the meeting rail 60 at the inner side thereof and includes top and bottom 5 walls 61 and 62, a downwardly extending lip 63 on the wall 61, and an upwardly extending lip 64 on the wall 62. The lips and walls jointly form a housing for a weather strip 65 which is triangular in form and which comprises a free resilient web 10 66 that extends downward and inward. The web 66 normally bears against the outer face of the lip 64.
The meeting rail 67 of the lower sash is provided with a sealing member 68 for cooperating 15 with the sealing member 59 of the upper sash. The sealing member 68 comprises upper and lower webs 69 and 70 and a vertical web 71 which serve jointly to partly embrace the rail 67. The upper web 69 has an outward extension 72 which ex<sup>20</sup> tends across and rests upon the top of the web 61 when the window is closed. The vertical web 71 has an angular extension 73 formed at the outer side thereof which includes a downwardly „<sub>r</sub> extending lip 74. The lip 74 has a beveled inner “° face which cooperates with a similarly beveled outer face of the lip 64. When the lips are forced into contact they coact to draw the meeting rails firmly toward the parting strip. At the same time the lip. 74 wedges in between the lip 64 and the spring web 66 of the weather strip 65 so that firm sealing engagement is provided at both the inner and outer sides of the lip 74. The angular member 73 forms an overhang which is very effective <sub>35</sub> for preventing ingress of rain or snow.
The extensions 68 and 59 travel in the plane of the parting strips but are made of less length than the distance between the parting strips. The parting strips are provided with wedge shaped <sub>4fl</sub> fillers 74α to engage the projections 68 and 59 in the meeting position thereof to seal the spaces between the projections and the parting strips.
The member 59 includes an edge flange which forms a retaining strip 58 for a pane.
<sub>45</sub> The lower rail 75 of the lower sash is provided with a downward extension or flange 76 which lies outside the lip 20 of the sill member 4. The flange 76 and the overhanging lip 20 serve effectually to prevent ingress of rain between the lower sash <sub>5n</sub> and the sill.
The lower sash is provided with metallic sash lifts 77 which are secured to the rail 75 by screws 78. The sash lifts 77 are provided with cam extensions 78α which extend downward and 55 inward. Sill members 79 secured to the sill by the screws 10 are provided with wedge projections 80 which engage between the projections 70α and the rail 75 to draw the lower portion of the lower sash inward so as to press the flange 76 firmly 00 against the lip 20.
It will be seen that a structure is provided in which the joints are all firmly sealed when the window is closed but in which the sashes are floatingly mounted so that all tendency toward 65 frictional obstruction or binding is obviated.
The embodiment illustrated in Figures 4 and 5 is in general the same as that of Figures 1 to 3. The principal difference consists in the fact that the frame members are made of extruded sec70 tions so that no reinforcing wood fillers need be employed in the retaining heads or parting strip. The sa..h structures 7α and 8α of the window may be identical with the sash structures already described in connection with Figures 1 to 3. The sill 75 member 4α is substantially identical with the sill member already described and differs principally in the fact that no shouldered seat for the screen is provided. The head 6α comprises an extruded metallic member 81 which is integrally provided with flange members 82 and 83 for housing a <sub>5 </sub>weather strip 84 similar to the weather strip 38 of Figures 1 to 3. The metallic member 81 is also provided with a bead or rib 85 for positioning and supporting a parting rail 86.
Each jamb 5α comprises an extruded metallic io member 87 which includes integral members 88 and 89 forming a housing for a sealing and guiding member 90 which is similar in all respects to the member 38 of Figures 1 to 3. The metallic member 87 further includes beads or flanges 91 to for positioning a parting strip 92 and a bead 93 for positioning a retaining strip 94. The retaining strip 94 and the metallic member 87 jointly form a housing for a weather strip 95 which is like the weather strip 38 of Figures 1 to 3. <sup>20</sup>
The form of embodiment disclosed in Figures 6 and 7 is to ail intents and purposes identical with that of Figures 4 and 5 with the exception that the non-ferrous members of the window frame are reinforced and made more rigid by steel <sup>23 </sup>members. The steel members are in every instance covered and protected, however, so as not to be exposed to corrosion. Thus, provision is made of a subsill member 96 which is of steel and to which the sill member 4b is secured. Pro- <sup>30 </sup>vision is also made of concealed jamb members 97 to which the jambs 5b are attached, and of a concealed steel head member 98 to which the head 6b is attached. Each of the members 96, 97 and 98 is in the form of a channeled angle bar which <sup>35 </sup>is rigid and strong for its weight.
The rigid buck of Figs. 6 and 7 is illustrated by itself in Fig. 8. The sill and head members 96 and 98 are shown in this figure as rigidly attached to the jamb members 97 by means of welding, <sup>40 </sup>although any other suitable form of rigid connection could be employed. The weld joints are indicated by series of small crosses in Fig. 8.
While we have illustrated and described in detail certain preferred forms of our invention, it is to be understood that changes may be made therein and the invention embodied in other structures. We do not, therefore, desire to limit ourselves to the specific constructions illustrated, but intend to cover our invention broadly in whatever form its principle may be utilized.
