This invention relates to Windows and in particular to an improved sash construction.
It is among the objects of my invention to provide a sash or styling for single or multiple glazed Windows that is airtight and Which readily accommodates and compensates for irregularities and variations in longitudinal and transverse dimensions of the glass window panel or panels as Well as unevenness on the cut edges of the glazing. Other objects of my invention are to provide a sash for windows Which securely binds the edges of the Window panel and yet readily accommodates relative thermal expansion and contraction between the glass panel and sash Without affecting the airtight seal of the glass panel in the sash; to provide a sash having a sealing strip which permits easy installation and framing of the glass panel or panels in the sash but which strongly resistsl removal of the glass panel or panels and sealing strip or strips from the sash; to provide a Window sash and one or more glass panels which may be assembled together as a unit structure without in some or many circumstances requiring the use of bolts, nuts, screws or other auX- iliary retaining means; to provide a sash and sealing means therefor which will removably accommodate double or multiple glazing; to provide a sash that may be rapidly and easily installed around the edges of single, double or multiple glazing thereby facilitating shipping and handling of same without danger ofv breakage and/or chipping of the edges of the glazing, and to provide an economical, light, easily made, substantially breakage-proof, durable and quickly repairable assembly of single or multiple glazing or other panelling and sash for handling, shipping, storage and use in windows or thel like. Another object of my invention is to provide a double or multiple glaze sash assembly in which the air or other gas or gases between the glazing may be conveniently evacuated, changed, driedor otherwise treated in situ or at any other time or place. Another object is to provide a sash with nxed external' dimensions that is capable of receiving single or multiple glass' or other glazing of varying dimensions. in air tight, weatherproof and strong resiliently gripped relation. Another object is to provide a dry glazed single or multiple panel sash obviating thev usel of putty, adhesives or other wet or plastic sealing or caulking compounds, solders orA materials;

Figures 15 and 16 illustrate a preferred form of notching. andv turning the' sealing strip at the corners of the sash.
The present invention is illustrated in an improved sash construction ior conventional Windows. Figure 1 shows a Window sash assembly W consisting of a glass sheet or panel I, a sash frame 2 surrounding the edges' of panelV I, and gripping and sealing means 3 disposed between the edges of panel I` and! thesash frame 2. My sash assembly may be used in any type-of window construction, either and preferably as an independently operated' and installed completesaslfi` or may be glazed into or incorporated with existing sash framesor other xed or movable apertures or openings.
The details' of construction of the sash are shown in' Figuresv 2, 3, 4,. and r4. The sasl-i, or
more specically the. sash frame 2 is comprised of a, top rail abottcm rail 5, and side` rails 6'- and l'. For convenience and clarity in explain-- mg the details of construction of my` invention,
reference'v will presentlyI be made only to one rail', y namely top: rari 4- sho-wn in Figure 2, since the 3 y top, bottom and side rails are substantially identical in form and coact with the seal and glazing in the same way. Rail 4 is preferably cut to proper length from suitable rigid material, l
such as aluminum, brass, steel or stainless steel, having a channel shaped cross section, and having an outer or base wall 8 and spaced parallel side walls 9 and I integral with and projecting inwardly from the base wall 8. The inner surfaces of walls 8, 9 and IB define an open rectangular recess in the rail which is adapted to receive the marginal and extreme edges of the glass or other panel I, In order to seal and retain panel I in rail 4, resilient gripping and sealing means 3 comprising a channel-shaped rubber or rubber-like sealing member or strip is disposed in recess |I between the edgesof panel I and the rail.
The sealing member or strip 3 preferably isA comprised of rubber or similar resilient material andmay be formed by extrusion through a die. The strip preferably is cut to a length substantially equal to the periphery of panel I so as to form a continuous seal between the panel and sash frame. The strip is formed with'a web I3 and spaced inwardly projecting legs I4 and I5 preferably formed integrally with web I3. Web I3 has an inner surface I6 and an outer surface I'I, and legs I4 and I5 have inner surfaces I8 and I9, respectively, and outer surfaces 20 and 2|, respectively. The inner surfaces I6, I 8 and I9 of web I3 and legs I4 and I5, respectively, define a slot or groove 22 in the strip 3, see Figure 4, into which the outer marginal and eX- treme edges of panel I are adapted to fit closely when the strip and panel are joined. The strip 3 is formed so that in its relaxed dismounted state legs I4 and I5 preferably tend to converge toward each other as shown in Figure 4. In order to fit the marginal edges of glass panel I into slot 22 of the strip, legs I4 and I5 are sprung outwardly from each other and thus tend, pro tanto, to grip the edge of the panel. When the panel edge is positioned in the slot 22 legs I4 and I5 tend to converge toward each other and inner surfaces I8 and I9 of the legs snugly engage the marginal sides of the panel whereby to retain the strip 3 on the edge of the panel as shown in Figure 3 at least initially and to aid in handling and assembly-with the sash frame.
In order to create and maintain an air tight seal and a strong mechanical grip between the strip 3, the panel and sash and to positively and effectively bind the window panel and sash together, a plurality of ribs 23 and 24 are formed integrally with legs I4 and I5 on their outer surfaces 26 and 2| respectively. In an exemplary strip measuring about 1 2 wide by deep overall in the condition shown in Figure 3, these ribs may be relatively small in size being about le" long from root to tip and about els" mean thickness and are preferably spaced on the surfaces 243 and 2| in the order of about 6 to 12 to an inch. Ribs 23 and 24 extend longitudinally of the strip and project from the respective legs I4 and I5 in an inclined direction away from the web I3, i, e., inclined to yield easily during entry of the strip into the recess of the rail and strongly resist removal of the strip from the rail. 'I'his construction permits the ribs to be pressed and folded inwardly toward or against the surfaces 20 and 2| of the strip under relatively small manual pressure when the sash rail is forced over and upon the sealing member as to the position shown in Figure 2, although the ribs when so folded or bent inwardly exert an outward resilient pressure back against the inner surfaces of the legs of the rail because of their resiliency. The overall width of strip 3 when mounted on the panel edge, that is, the distance between tips of ribs 23 and 24 as shown in Figure 3, is about ie" in the exemplary form mentioned above and is about greater than the corresponding distance between inner surfaces of side walls 9 and I0 respectively of the rail, that is, the width of recess II. When strip 3 is telescopically fitted into recess Il, ribs 23 and 24 will engage side walls 9 and I respectively and will be folded or displaced inwardly toward or against the outer surfaces and 2| of legs I4 and I5 as the strip and panel are moved into the recess and at the same time will press outwardly against the inner side walls 9 and I0 of rail 4 as Vshown in Figure 2.
When the strip 3 with panel I mounted therein is inserted into recess I I, frictional resistance to sliding between the engaging surfaces of the rail and the ribs is compensated by the inwardly yielding folding action of ribs toward or against the outer surfaces 2B and 2| of the legs I4 and I5, respectively. Thus, insertion of the strip into the recess of rail 4 during assembly of the sash and glass panel is but lightly resisted. However, once the glass panel, sealing strip and rail have been joined as shown in Figure 2, frictional forces opposing removal of the strip and panel from the rail become exceedingly high. The reason for this action is that intended movement of the panel in a direction away from the rail and out of recess causes the ribs 23 and 24 to tend to unfold or expand outwardly and correspondingly increase the eiective thickness of the rubber and multiply the frictional grip between the sealing and gripping member 3 and the rail and the panel. Thus, high frictional resistance which increases with the force tending to remove the panel from the rail substantially prevents disassociation of the panel, strip and rail and the window panel is securely and tightly locked and sealed in the rails of the sash frame.
As previously mentioned, legs I4 and I5 of the strip 3 converge toward each other when the strip is dismounted from the panel I. This preliminary engagement of the legs of the strip against the peripheral margin of the window panel is increased when the strip and panel edge are inserted into the recess of rail 4, and when the panel is sought to be separated from the rail the compressive engagement and frictional bond between all the parts is mightily increased as described above. When it is desired to remove the glass panel from the sash, as for example, in
the event of window breakage, a small amount of kerosene or other light penetrating oil may be deposited on each side of .the glass panel at the junction thereto kwith the strip 3. The oil penetrates between the surfaces of the glass panel vand the inner surfaces I8 and I9 until the coefficient of friction between the strip and panel is loosened suciently to permit the glass to be withdrawn from the strip. If the strip 3 is composed of natural rubber the application of kerosene or the like may be detrimental to the structure of the material; in which case the rubber strip may be replaced with a new one before reassembling the sash frame and panel. Often a prompt wiping olf of the kerosene will preserve the strip for repeated use. However, if the strip Vis composed of such material as synthetic rubber and the like, deterioration fromkerosene is less likelyy and it is only necessary that the strip be wiped clean of the` oil in order to restore its coeiicient of friction for use again in the sash frame.
As shown in Figures 2, 3 and 4, I prefer to form the sealing strip 3 with outer integral flanges 25 and 25 on the free endsl of legs ld and l5 respectively. These iianges project outwardly from the ends of the legs and are adapted to overlay the inner portions of the ends of the legs 9 and I0 of the rails and effect engagement therewith as the strip and/or strip and panel are inserted into the recess tI of the sash rails. Thus, flanges 25 and 26 act as yieldable stops to limit the movement of the strip into the recess of the rail and to locate the strip in the sash. In addition, flanges 25 and 26 facilitate the weatherproofness of the seal and are preferably tapered at their outer ends to merge with the curves of the ends of the legs to spill rain, wash water, etc., from the glass out over the exterior of the rails. As also shown in Figure 14 the free ends of the legs 9 and Hi are rounded at their inner and outer corners; the former facilitating smooth entry of the strip and panel into the recess II, wiping and folding or bending the ribs 23 and 'Ze without tending to shear or sever the same from the strip during its entering movement into the recess, and the latter merging in contour with the tapered ends of the iianges 25 and 2S through a wide range of positions of the iianges according to the depth of entry of the strip into the recess, as suggested by the contrasting positifns shown in the right and left parts of Figure 14.
Referring now more speciiically to Figures 2, 5 and 14 the facility with which my sash accommodates irregularities in the shape and contour of the panel I within fixe-d sash dimensions is suggested. In Figures 2 and 5, the extreme outer edge 28 of the panel I is shown as having detailed irregularities departing from straightness as often occurs in the cutting of glass. Here the high parts have merely exed the web I3 of the strip 3, see also the dotted lines in Figure 2, toward the base wall 8 of the rail without substantially drawing or urging the legs I4 and I5 of the strip inwardly beyond their normal position in the recess as suggested by the full overlap of the flanges 25 and 26 with respect to the rounded ends of the legs 9 and I0. The low points of the irregular edge 23 need not necessarily touch the web I3 of the strip; the essential grip and seal between the strip and panel being made on the marginal edges of the panel between the surfaces It and I9 and the yieldability of the web I3 taken with its spacing from the base 8 of the rail accommodating these irregularities in the edge 28 without bottoming the strip or edge, thereby preserving the edge in the nrst instance and accommodating relative thermal expansion and contraction between the parts in use.
Since it rarely happens that the panel I is cut truly square it will often happen that the edge of the panel will extend more deeply into one rail or one part of a rail than another. As suggested in Figure 14 the strip 3 accommodates this kind of irregularity without loss of gripping or sealing efficiency and without substantial change in finish or appearance. On the left side of Figure 14 the parts are shown in the mean or normal relation similar to that of Figure 2 With the flange making full contact with the end of the leg of the rail but not being substantially flexed thereby. Here the edge 23. is shown `just contactingy the web I3'v and the web in turn is well spaced from the base of the rail as by about 1A," where the other dimensions are as given above and the `panel is normally proportioned in respect to. the` rail.. The right side of Figure 14 shows how my invention accommodates. an oversize panel or a panel having an oversize dimension. Here the whole strip enters the recess II more/deeply carrying the web and legs thereof deeper into the recess and drawing the inner portion of the flanges, as illustrated by the flange 26, partly into the recess. The outer part of the flange with its tapered extremity still makes smooth tight contact with the rounded end of the leg of the rail and presents the same finished appearance and substantially the same contour or the so-called normal condition. Again the web of the strip is still spaced from the bottom of the recess with the advantages above mentioned, the same being accomplished by making the recess enough deeper than the normal depth of the strip, as measured from the flanges to the-exterior of the web, to accommodate all reasonable errors in panel size and shape and still have a space between the bottom of the recess and the bottom of the strip.
One exception to this latter teaching has occurred in my experience, namely, when the glazing or panelling is heavy as in a large multiple glazed sash the glazing and strip may tend to work down into the bottom rail under the iniluence of gravity and use of the window more than I desire. Against such contingencies I have found it practicable and advantageous to insert a pad or cushion in the bottom of the recess of the bottom rail of depth approximately equal to the normal space between the webs 8 and I3 as shown at the left of Figure 14 so that the web I3 of the strip and the glazing may have soft somewhat yielding support distributed between the high and low parts of the bottom edge of the glazing equally enough to resist cracking of the glass and cutting of the strip. I have found a soft wood pad practicable; the rubber Voi the web I3 of the strip tending to cold-flow and distribute the load from the high parts to the low parts of the glazing satisfactorily.
There yet remains the accommodation of variations in thickness of the panel in relation to the desired constant width of the recess II. In single glazed sash the variation is ordinarily small enough to be compensated for in the extent of the bending and flattening of the ribs 23 and 24; their functions and effects not being deleteriously impaired in the range between substantial flexing on the one hand and complete bending to bottom against the surfaces 29 and 2| on the other hand. Where greater accommodation is desired the inner surfaces I3 and I9 may begrooved, serrated or corrugated as show-n at 59 in Figure 8 so that the attening of the ridges of the serrations will facilitate greater tolerance of variations in panel thickness.
Figures 6, 7 and 8 show a modification of my improved sash for accommodating double glazing. Sash 3d is comprised of top rail SI, bottom rail 32, and side rails 33 and 3d, all of which rails are substantially similar in form and shape. Each of the rails 3i and 32 has an outer wall 35 and side walls 36 and 3l projecting inwardly from wall 35. The inner surfaces of these walls deiine vrectangular recesses 4I in rails, corresponding to the recess II except in size, which are adapted to receive the edges of spaced parallel glass panels 43 and 44. In order to seal; space "i and securely hold the panels 43 and 44 in the rail recesses and to space the panels from each other, a sealing member or strip 45 of rubber or rubber-like material corresponding generally to the strip 3 adapted to be inserted in the recesses of the rails is provided. This sealing member preferably is a single strip designed to extend around the entire peripheries of panels 43 and 44. Although I prefer to use a single sealing strip, it will be understood that individual strips cut to the length of each rail member, respectively, may be employed without departing from the spirit of my invention.
Sealing strip 45 consists of a web 41, inwardly extending side legs 48 and 49, and an intermediate leg or dividing partition 59. Legs 48, 49 and 59 are preferably formed integral with web 41. The intermediate leg 50 is spaced from the side legs 42 and 49 thereby -dening slots 5I and 52 between the side legs and leg 59 for receiving the extreme and marginal edges of panels 43 and 44, respectively, which extend longitudinally of the strip. When panels 43 and 44 are mounted in the strip with their edges disposed in slots I and 52, respectively, as shown in Figure 7, intermediate leg 5! serves to separate the panels so that a space 53 exists between them. It is well known that provision of a space, commonly known as dead air space, between the panels of a window assembly greatly increases the insulating characteristics of the window and reduces heat loss therethrough.
As described in connection with the sealing strip 3 shown in Figures 2, 3 and 4, legs 48 and 49 of the strip 45 are provided with sets of external integrally formed longitudinally extending ribs 54 and 55, respectively, which project outwardly from the legs and away from the web 41 and perform the function of the ribs 23 and 24 of the strip 3. Flanges 56 and 51 are formed on the free ends of legs 48 and 49, respectively, which flanges cooperate with the rail into which the sealing strip is inserted to properly position the strip therein and to perform the other funce tions ascribed to the flanges 25 and 26. The surfaces on intermediate leg 50 adjacent the slots 5l and 52 are preferably formed with a plurality of longitudinally extending serrations 59 adapted to contact the inner surfaces of panels 43 and 44 and which provide leg 5D with sufficient resilient effective compressibility to help accommodate for variations in thickness of the panels and relative thermal expansion and contraction of the panels and the sash.
As shown in Figure 8, strip 45 is formed so that in its relaxed state when dismounted from the edges of the window panels, side legs 48 and 49 converge or tend to converge inwardly toward leg 5G. This construction affords a gripping action tendency of the strip on the edges of the panels whereby to retain the panels in the slots 5I and 52 in the manner described previously and/or to hold the strip on the edges of l the panels preliminary to assembly in the sash rails.
In the assembly of the double glazed window unit, the sealing member or strip 45 is first mounted on the edges of panels 43 and 44 so that the edges of the panels are disposed in slots 5l and 52 of the strip. It is not necessary that the edges of both panels set tight against the inner surfaces of web 41 as pointed out heretofore in connection with the single glazed window, nor that the panels be identical or precisely the Asame shape as the differences between the panels. Thereafter the strips embracing the marginal edges of the panels are telescopically joined with the rails as more fully described above so that the strip is disposed within the recess in the rail with flanges 56 and 51 on the strip in engagement with the rounded top edges of side walls 36 and 31 of the rail. When the panel and sealing strip are moved into the recesses in the rails, ribs 54 and 55 engage the side of the rails and bend or fold inwardly against legs 48 and 49 of the strip and thus offer little resistance to this movement. However, if a force is applied which tends to separate the rails from the panels the ribs 54 and 55 will tend to unfold and expand outwardly against side walls 36 and 31 of the rail and resist this movement. Thus, the panels 43 and 44 are securely sealed, spaced, resiliently supported and retained in the sash.
In order to afford and control communication with the space 53 between panels 43 and 44, apertures 69 and 5l are drilled and tapped in the outer walls, such as 35 of the sash rails, and are adapted to receive smooth-ended screws 82 and 63 Y which are aligned with apertures 64 and 55 formed in the intermediate leg 5l) of the strip opposite the apertures 60 and 5l, respectively. Preferably the rounded ends of the screws seat on and at the marginal edges of the apertures 54 and 55 and close these apertures in the innermost position of the screws and open these apertures when the screws are backed out and/or removed tures 60 or 6| for the movement, treatment or change of the contents of the space 53. If, for example, a dehumidied gas is to be admitted to the space 53, the source or" such gas is connected to the aperture opposite a vacuum pump means and the space 53 filled therewith as the original gas is removed. After the operation is completed, the screws E2 and 53 are screwed down tightly Y against the rubber strip thereby sealing the holes 64 and 65. Similarly dehumidifying agents may be injected into the space 53 through either orv both apertures.
In order to adapt one sash or window frame so that it will accommodate either single or double i glazing, the single glazing strip 3 and the doubleV `glazing strip 45 of my invention may be formed with the same gross exterior dimensions so that either strip will nt tightly into the same recess converted readily from single glazing construcl tion to double glazing construction or vice versa by merely selecting a single or double glazing i sealing strip for assembly in the sash. This feature of my invention permits conversion from single glazing construction to double glazing sash or as each other; A the nature of the strip making the accommodations discussed above and also accommodating -9 construction by mere replacement of the sealing strip without necessitating replacement of -the sash. Since the cost of the sealing strip is small compared to the cost of the sash, substantial savings'are effected.
Figures 9 and 10 show particular modified forms of a single glazing strip 'I0 and a double glazing strip 80 of like external conformation and size. In this case, strip '10 is substantially the same as strip 3 described above except that legs and '|2 have greater effective width and are, however, preferably undercut as indicated at 13 and 14, respectively, adjacent the web portion '15. The purpose of undercutting the legs is to eiect economy in fabrication of the strip by reducing the amount of rubber or other material used in the strip. The thickened portions i@ and 11 of the legs serve to engage and tightly grip the panel I disposed therebetween in the manner described above. The intermediate leg 8| of strip 80 shown in Figure 10 is likewise undercut adjacent the web 84 as indicated at 82 and B3 while serrated thickened portions 85 and 85 at the far end of leg 8| engage and grip the panels `43 and 44. Preferably the thicker far end of leg 8| has a longitudinal aperture 8T which with the serrations lends greater effective lateral resilient compressibility to accommodate variations in panel thickness and maintain an eflicient grip and seal withall when the sash is assembled. In other respects, strips 'i0 and 80 function in the manner described above.
Whether in single or multi-glazed forrn the seal and bond established through the strip between the sash rails and the panel or panels of the glazing is such as to hold the several parts together in tight and secure assembled relation. In fact the bond is such that for many purposes no other means are necessary to secure the sash rails in the desired relation to each other and to the glazing. For example, in windows where the sash are pivotally supported in the middle of the bottom rail the mechanical bond afforded by the strip more than suffices for all manner of shipping, storing, handling and use of such rails. On the other hand where the sash are to be suspended from the top rail and particularly where the glazing is large and heavy, I prefer to augment the strength of the sash by connecting the ends of the rails together as by the means suggested in Figures 11, l2 and 13 of the drawings. Thus the ends of adjacent sash rail members are joined together in an overlapping relationship to form a tight, strong, light proof joint. As shown in Figures ll and 13, slots 93 and 9| are milled in top rail 3| to a. depth substantially the same as the depth of the recess in the sash. Alternate rails, the vertical rails 33 and 34 in this instance, while having the same internal recess, size and shape as the top and bottom rails, are of lesser width by virtue of having thinner side Walls or legs 39 and 43 which leave a snug sliding t in the slots S3 and 9|. When the side rail 34 is joined to the tcp rail 3|, side walls 39 and 4B of the side rail (it into the slots 9) and 9| until the outer wall 38 of the side rails 34 abuts the end of the outer wall 35 of the top rail 3| as shown in Figure l2. The ends of the outer and side walls of the side rail lie hush with the exterior surface of the outer Wall 35 of the top rail as also shown in Figure 12. The slots 9b and 9| cut through the outer wall 35 of the top rail, Figures ll and '12, and cut away the inward parts of the ends of the side walls 3S and 31 of the top rail to a depth corresponding to the thickness of the legs 39 and 40 of the side rail so that the inner surfaces of the legs of the side rail and the inner surfaces of the legs of the top and bottom rails lie ush as at S2. Thus the recess 4| is common to all rails and identical throughout the whole sash. A pin Se or other suitable fastening means may be inserted through aligned apertures drilled transversely through the ends of the side walls oi the side rail and the outer wall of the top rail, Figures 11 and 12, to secure the rails together. The connection between rails ends described with particular reference to Figure 6 also applies to yFigure l. K
I have mentioned my preference for using a single sealing 'strip to be carried around the whole periphery Vof the panel or glazing. In such event I prefer to cut V notches through the side walls ofthe strip as shown in Figure 15 to turn the cornersA of the strip around the corners of the glazing as shown in Figure 16.
While I have illustrated and described preferred and certain .modified forms of my invention, changes, improvements and further modications will occur to those skilled in the art who come to understand the principles and advantages of my invention, and I do not care to be limited in the scope of my patent to the forms herein speciiically illustrated and described nor in any way inconsistent with the advance I have made over the prior art.
