"WILLIAM BAILEY, OF SPRINGFIELD, OHIO.

. wmnow-sAsH MOUNTING.

Application filed April 11, 1922. Serial No. 551,719.

My invention relates to window sashes and more particularly to a mounting and method of installationfor metallic Window sashes such as are commonly employed in I factory and warehouse constructions.

It is the usual. practice in installing window sashes of the metallic type,to leave in the margins of the Window openings or spaces, enlarged recesses, which after the sash has been properly positioned by. means of wedges and space blocks, is filled with concrete, thereby directly embedding the margins of the sash. Such construction is not only expensive, but it necessitates the introduction of a craft other than that directly interested in the installation of the windows.

The present invention contemplates embedding in the margins of the window opening or space a channelled window frame formed from sheet metal, having therein a medial upstanding plait, opening into the window space to receive the marginal flange of the metallic window sash which is projected into the plait or channel of such frame member, and held by a flexible tongue or closure strip or contracted mouth which readily accommodates itself toinequalities of the sash flange and variations of'its p0 sition of adjustment within the open plait or channel.

The object of the invention is to simplify the structure as well as the means and mode of operation of metallic sash mountings,

whereby they will not only be cheapened in construction, but will, be more efficient in use, durable, enabling the window sash to be easily and quickly installed, and unlikely to get out of repair.

A further object of the invention is to provide an improved form of window molding adapted to receive the margin of the sash to variable depth to afford a wide range of compensating adjustment, and to be directly embedded in the building structure at the time of its erection.

A further object of the invention is to provide an improved means for securing the window sash in position and closing the re- 50. ceiving recess, to prevent the entrance of air and moisture.

With the'above primary and other incidental objects in view as will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their equivalents as hereinafter described and set forth in the claims.

The window sash mounting and mode of installation forming the subject matter hereof 1S capable of embodiment in a great number of modifications, varying in details of construction, outline or contour, but all embodying the same essential elements, and novel features.

In the accompanying drawings, Fig. 1 is adetall sectional perspective view of a portlon of a window structure, illustrating the preferred form of mounting, and mode of installation of the metallic sash. Fig. 2 is a detail perspective view of the window frame molding. Fig. 3 is a detail perspect1ve view of the closure tongue or filler strip, before being embedded in the concrete orother building structure. Fig. 4 is a detail end view of the Window frame molding and closure tongue or filler strip, showing these parts mounted in the usual form or mold, preparatory to pouring concrete or other plastic material thereabout. Figs. 5 to 15 illustrate numerous modifications and variations of the window frame molding and closure means therefor. Fig. 5 illustrates a corrugated closure strip or tongue of resilient character. Fig. 6 discloses a channel shaped frame molding having an inturned plait or fold, projecting within the channel and deformed by the insertion of the sash' flange as shown in Fig. 6. Fig. 6 is aview similar to Fig. 6 showing the sash in place. Fig. 7 is an end view of the frame molding showing a contiguous plait or fold, forming one edge of the flange receiving channel. Fig. 7", shows this fold or plaitswedged or bent inwardly against the inserted sash flange. Fig. 8 discloses a modification, wherein a corrugated filler strip is bent upon itself and straddles the inserted sash flange. Fig. 9 is an end view of a frame molding similar to that shown in the principal figure or the preferred form, except the closure tongue or filler strip is formed integral with the molding. Fig. 10 illustrates a modification wherein the closure tongue or filler strip is carried by the inserted sash.

flange and bears against the inner wall of the channel. This construction is a reversal of that shown in the principal views, Figs. 1, 2 and 3. Fig. 11 discloses a modification quite similar to that shown in Figs. 'Zland 7. Fig. 12 is an end view of a further modification of the window frame molding, wherein the closure tongue or filler strip is slidingly adiustable and abuts u on the sash flange.

gated filer strip, somewhat similar to thestructure in" Fig. 5. Fig. 14 shows an end view of a window frame molding, similar in general design to that in Fig. 9, except that the mouth of the channel is contracted, affording an inwardly expanding plalt, which afiords anchorage in the building structure.

. Fig. 15 illustrates a molding of similar outline, but employing a filler strip having a I laterally flanged edge which operates as a wedge when driven into the mouth of the channel, beside the inserted flange. Fi V 16 is a detail perspective view and Figs. 1 18 and 19 are end views of modifications of the construction heretofore shown, wherein the channel has a contracted mouth, one side of which forms a fulcrum for lateral tilting adjustment. Figs. 2() and 21 show the range of lateral tilting movement. Fig. 22 illustrates the mode of securing the channels within the: concrete form.

Like parts are indicated by similar characters of reference throughout the several views. The present practice in installing or setting metallic sashes is illustrated in Fig. 4 wherein 1 is the wall of the structure, havinv in the edge of the window space a recess indicated by the dotted lines 2; The sash 3 is mounted in the opening with the'marginal flange 4 projecting within the enlarge recess 2, and this recess is afterward filled with concrete or cement as at 5. It is rather a diflicult operation to fill these recesses with fluid or plastic cement particularly those of the window head, as well as the sides. Moreover, under the present rule of the building trades, this work must be done by a concrete worker thus necessitating the employment of workmen of different craft, for inserting windows by this method.

To overcome these disadvantages, there is provided in the present construction as shown inFig. 1, awindow frame molding 6, comprising a strip of sheet metal, having therein a medial upstanding plait or fold 7, formin a flange receiving-channel 8, from the mout of which extends laterally and outwardly wings or flanges 9. The margins of these lateral wings or flanges 9 are bent at right angles at 10 and preferably notched as at.11, to afford suitable anchorage in the structure wall 1. The particular shape of the fold or plait 7 may be varied at will. In the principal figure, this plait has been shown with one straight side and one inclined or diagonal side. It may however, be rectangular in form as shown in the Figures 6, 7 9 and 11, or it may be oval as in Figs. 14 and 15, or provided with converging walls as in Fig. 8 or divergent walls as in Fig. 12. This molding 6 is embedded about the window opening and at the same time there is embedded in the wall structure a closure tongue or filler strip 12, having an upturned flanged edge 13, provided with anchorage notches forming tongues 14. This closure tongue or filler strip 12 extends exterior-1y of one of the laterally disposed wings or flanges 9 of the window frame molding and overhangs the grooved recess S. The overhanging portion 12' of this closure tongue or filler strip 12 is flexible and.

Fig. 3B preparatory to pouring the concrete therea out. In installing the window sash as shown in Fig. 1, the marginal flange 4 of the sash 3 is thrust within the recess or channel 8 of the window frame molding, thereby flexing the overhanging portion of the closure tongue or filler strip 12, placing it under tension which causes it to conform closely to the inserted flange 1, of the sash. This tongue or closure strip 12 is sufliciently flexible and yielding to automatically conform to the flange 4 of the sash 3. While a degree of elasticity or springiness in this 010- sure strip is desirable, themere resistance to bending or flexing movement will be suflicient to conform the strip to the inserted flange and thereby close the mouth of the channel 8, and hold the flange 1 of the sash in contact with the opposite wall of the channel. To facilitate this bearing and insure a close contact between the closure tongue and the flange, the end of the closure tongue' or filler strip 12' is preferably though not necessarily slightly rounded or flexed inwardly as shown in Fig. 3.

The construction in Fig. 5 is quite similar except that the insertion of the sash flange tends to flatten or distort the corrugated insert or closure strip 17.

In Fig. 6,,the' closure member is formed integral with the window frame molding b the formation of an inturnedplait 18, whic overhangs the mouth of the channel 8, in somewhat the same manner as the closure tongue 12. The insertion of the sash flange will distort this plait as is shown in Fig. 6. The distorted plait, however, will conform to the sash flange and effect an air and moisture tight joint. At the same time the flange is held in close contact or abutment upon the opposite face of the channel 8. In Figs. 7 and 11 the closure flange or filler strip is likewise formed by an integral plait, which, however, in these instances is coincident with the one side of the flange receiving channel 8. This closure tongue is adapted to be swedged or flexed into close bearing upon the inserted flange by means of a tool as shown at 19 in Fig. 7*. As before mentioned the structure shown in Fig. 9 is quite similar to that shownin Figs. 1, 2 and 3, except that the closure member is integral with the window frame molding. The operation and result are as before described. In Fig. 8

the closure of the window frame channel is effected by means of a corrugated channel 20,

- tension as the flange is forced within the channel 8, causing its free edge to bear outwardly upon and conform to the inner face of the channel wall. In Fig. 12, the closure strip 22 rests against one of the face flanges of the window frame molding, but overhanging the channel. In this case, however, instead of being flexed inwardly-as in the principal construction, the closure strip is preferably slotted as shown by dotted lines and is adjusted straight inwardly with its edge abutting upon the inserted sash flange at. Fig. 13 discloses a channel molding made up of separate members, connected together by riveting, welding or otherwise with their inner margins out-turned to form anchorage flanges. This particular form of molding has been shown in conjunction with an insert or filler strip similar to that shown in Fig. 5. It is to be understood, however, that any of the other types of closure tongue or filler strip may be employed. Fig. 15 shows as a further modification, the use of a wedge strip 23 in this instance comprising a strip of sheet metal having one edge flanged laterally, the flanged strip being driven edgewise within the mouth of the channel or groove in the window frame molding. Thus exerting lateral pressure upon the inserted sash flange 4. Thus in each instance the invention involves a window frame molding permanently embedded in the structure and having a grooved recess communicating with the window space to receive the marginal flange of the sash, the grooved recess being closed and the sash held in adjusted position by a deformable or yielding closure strip carried by one of the members and bearing upon the other, to support the sash and close the mouth of the recess against the passage adjacent to site lip 25 is rigid and is somewhat in the form of an inwardly projecting head, which forms a fulcrum for the sash, upon which the sash is capable of a limited laterally tilting movement, by which it may be accommodated to various irregularities and afford a considerable range of adjustment. This lateral tilting. adjustmentin clearly illustrated in Figs. 20 and 21. \Vhile the sash may be rocked to and fro upon the inwardly projecting rigid flange or lip 25, the flexible lip 24 will in all positions engage the sash to seal the mouth of the channel. The flexible or yielding lip 24 may extend entirely across the mouth of the channel to close proximity to the fulcrum lip or bead 25, as in Fig. 17, or it may be somewhat shorter and terminate in spaced relation with the fulcrum bead or.lip 25 as shown in Fig. 18. Further to accommodate the structure to various conditions of use, any of the forms shown may be modified by notching or cutting away spaced portions of the flexible closure strip, or lip as shown at' 26 in Fig. 17 The construction shown in Fig. 19, shows both lips of the contracted orifice of. the channel as flexible or yielding. This construction will readily accommodate itself to inequalities in the edge of the sash, without subjecting the sash to lateral strain or any tendency to spring the sash out of its normal plane.

The molding 6 of sheet metal may be partially opened or distended to enable a number of strips of molding to be nested or introduced one within the other, for storage and shipment. A convenient method of loeating the molding within the concrete form is shown in Fig. 22. This consists in drawing a chalk line 28 longitudinally upon the form and locating therein in spaced relation a number of nails 29. One side of the channel 8 of the molding is abutted against such nails, and the flange 9 of the molding is secured by drivin nails 30 therethrough, directly into the orm board. After thus securing one of the lateral wings 9 of the molding, the opposite wing is flexed downward until the mouth or lip of the channel also contacts the abutment nails 29, when its lateral wing may also be secured to the form board. I a

The various forms of construction heretofore referred to and as shown in the drawings, afford a wide range of compensating adjustment, by providing for clamping the margin of the sash at whatever depth it may be necessary. to insert it within the channel. For instance, Fig. 6 shows a sash margin inserted to its full depth within the channel, while Fig. 7 discloses it as only partially entered. Yet in both instances it is fully supported and sealed. Figs. 20 and 21 show a wide range of lateral tilting movement while still maintaining the supported and sealed relation of the sash. Thus the. different forms of construction afford a wide range of compensating variation. or relative positions of the sash within the channel, while maintaining the maximum efiiciency of the device. A

While dove tail notches and tongues 11 and 13 have beenshown in Fig. 2 to afford anchorage for the strip. it will be obvious that other forms of anchorage may be employed as for instance, the lateral fianging of the edges of the strip as shown at 31 in Fig. 17, or 32 in Fig. 19, or these anchorage flanges may be perforated as at 33' in Fig. 18. Any suitable formation which will secure the molding strip firmly embedded in the concrete material will fully serve for the anchorage purposes.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable. but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific details shown, but
