METAL WINDOW-SASH.

Specification of Letters Patent.

Patented May 12, 1908.

Application filed October 20, 1906. Serial No. 339,783.

To all whom it may concern:

Be it known that I, ERNEST FLAGG, a citizen of the United States, residing at New York city, county and State of New York, have invented certain new and useful Improvements in Metal VVindow-Sashes, of which the following is a specification.

This invention relates to window construction and particularly to window construction of the metallic type.

An object of the invention is to so shape, proportion and combine the various elements of a window, comprising sash, frame, etc., that the structural qualities peculiar to bent metal will be employed advantageously, to minimize the material and the labor necesfor. the construction of a satisfactory fireproof bent metal window.

In this general type of window it is customary to provide a sash and one or more panes seated therein so that a metal surface or part is on each side of the margin of a pane, the pane, therefore, being held positively by the sash against lateral removal I from either side somewhat as is the case with a door panel.

In my co-pending application, Serial No. 356,553, I have claimed broadly a construc tion which provides for the ready removal of a pane, by arranging for the immediate detachment as an entirety of one or more rails of the sash, preferably the top rail and have shown ellic-ient means for connecting the removable rail to its abutting rails and also eiiicient means for securing said rail to a muntin, if a muntin is to be employed. Inasmuch as this construction is closely related to and intimately associated with the invention set forth herein, I have included an illustration and description of the same in this case.

Further objects are to provide an efficient bent metal muntin and bent metal sash rail furthermore, to provide a sash comprising bent metal rails of the same cross section; and also to provide a suitable metallic window frame which will cooperate with such a ash.

Still further objects are to combine and adapt various elements so as to cooperate in furthering the general object of this invention.

Reference should be had to the accompanying drawings forming part of this specification, illustrating an em )odiment of the'invention and in which may be desired.

Figure 1 is a sectional elevation taken through line 11 of Fig. 2; Fig. 2 is an interior elevation of the window but with parts broken away; Fig. 3 is a horizontal section through line 3-3 of Fig. 2, but showing the window complete Fig. 4 is an enlarged (letail section taken along line 4-4 of Fig. 2, but with the top sash lowered and the bottom sash raised Fig. 5 is an isometric view of a portion of the top rail of the lower sash and showing the corner angle iron; Fig. 6 is an isometric view showing the meeting rails of the top sash and the lower sash and. the interlockmg weather seal; and Fig. 7 is an isometric view showing in detail the end of a muntin in combination with two panes.

Referring now more in detail to the drawings:-1 designates the window frame, which comprises jainbs 2 and 3, sill I, and head 5. The upper and lower sash are designated by 6 and 7, respectively. Sash 6, as shown, comprises stiles or vertical rails 8 and 0, top rail 10, bottom rail 11 and muntin 12. The top rail of sash 7 is designated by 13, the bottom rail by 14, the right hand stile by 15 and the muntin by 16. 7

Although one muntin 12 is illustrated separating panes l7 and 18 in sash 6 and one muntin loseparating panes l9 and 20 in sash 7, it is to be understood that each sash may be provided with any number of vertical and horizontal muntins, or with none at all, as In case none were provided, each sash would contain but a single pane.

It is preferred that each sash rail be of the same uniform cross section and preferably that shown in the drawings. The cross section of the sash rail is best shown in Fi s. 4 and 6. A single strip of sheet metal is bent on itself along longitudinal lines to form the molding 21, which has a flat face 22 substantially at right angles to face 23. The ed e of the metal strip cont inning from face 22 isbent out at right angles to 22, then again at right angles to itself and then back at right angles to face 22, as shown, to form part of a flange 25. The edge continuing from face 23 is bent out at right angles, then parallel with face 23 and, on a line parallel with and flush with the outer edge of 23, it is doubled back on itself. This bending forms a groove pane seat 24, which is approximately alined with and substantially a counterpart of the flange 25 extending at right angles to face 22. This rail construction may be made in stock lengths; then cut into proper lengths for the respective sash rails, each rail being preferably mitered at its ends.

Figs. 4 and 6 show a preferable manner of connecting abutting rails. .Some reinforcement, such as an angle iron 26, has one leg inserted within the hollow flange 25 of a rail end.

by suitable means, such as soldering, brazin or riveting, etc. In a similar manner eac rail may be secured to the inclosed leg of the angle iron. It is, however, to be understood that the sash rails maybe joined without the aid of the reinforcing angle iron 26. N evertheless, it is preferred to employ the angle iron when joining the top rail pf each 'sash to the abutting stiles. Figs. 4, 5 and 6. In this case the legs of the angle irons 26 are tapped to receive screws 27, which extend through the side of the flange 25 to clamp the parts together. removing the screws 27, the to rail may readily be detachedand remover as an entirety. It may be replaced as readily. This feature permits a ane to be slid home in the roove seats 24 lilge a shutter, where it may 5e locked in place by the attachin of the top rail. Cement28 may be used in the seats 24. Any number of sash rails may be oined to the abutting rails so as to be removable as an entirety, the same as hasbeen described in.

connection with the top rails.

The sash bar or muntin, shown in detail in Figs. 3 and 7, com rises two bent metal strips and means to c amp them together.

29 is a molding strip with its two edges 30 and 31 bent inwardly as shown. The edges 30 and 31 engage the interior face of the anes as shown. 'A second metal strip 32.

as each edge 33 and 34, doubled over on itself and then outwardly near the medial line of the strip as shown in Fig. 3. The outturned edges 33 and 34 form spacing abutments. A strip or series of washers 35 engage the edges 30 and 31 and by means of bolts 36 or their equivalent, which pass between the edges of the panes l7 and 18 and suitably engage the strip 32, the strip 32'is clamped towards the molding. The abutments 33 and 34 limit the clamping effect of bolts 36 upon the two stri )s which are preferably of such a depth t at the space between the strip 32 and the edges 30 and 31 is the same as the width of the other pane seats 24. At each end of the muntin the molding 29 is cut off on a curve, so as to fit the molding of the sash rail, such as rail 10. The

Such a joint is shown in.

ma be clam ed a ainst t body portion of strip 32 is preferably squared off, leaving projecting tongues 33 and 34, being contmuations of the abutments 33 and 34. These tongues are designed to fit snugly in a pane seat 24 of the sash rail and secure the muntin. If desired, they may be long enough to penetrate the bottom of the pane seat .24 or may merely engage the side walls of said seat and stop short of the bottom of the pane seat.

With a sash built up as described from rail construction of the section shown, there is provided a flange 25 on all the edges of the sash and extending at right angles to a flat face 23. This flange forms the runner memher and weather flange for the sash, particu larly that on the stiles.

Each jamb comprises a bent metal shell formed of a single strip of metal. The pulley face of each jamb is formed with an integral parting ridge 35 with vertical side edges 36 and 37 at right angles to the faces 38 and 39 of the jamb. The sash slide on opposite sides of these parting ridges, as shown. The sash flanges 25slidably engage the vertical faces 36-and 37 and are retained in place by vertical guides, preferably angle strips 40 and 41, which are removably secured to the jambs-as shown.

Mounted in the jamb there'may be provided a clamping device or sash fast. Such a fast is indicated by 42. Its 'aws 43 and 44 he flanges 25 through the ho es 45 and 46 provided in the vertical faces 36 and 37. i

Each jamb provides suitable runways for- X separating .strip 48 maybe provided as shot n.

sash weights indicated by 47. v

49 indicates suitable pulleys over which theloords or chains, such as 50 may run. Ren'iovabi sections may be provided in the jambs to give accessto their interior Such a section is indicated by 51.

In the embodiment of the invention illustrated the parting ridges 35 separate the sash a sufficient distance to )ermit of the provision of a suitable interl ocking weather closure for the meeting rails 11 and 13 of the two sash. Secured to flange 25 of rail 13 is-a bent metal hook-shaped strip 52, coo mating with a mating L-shaped bent metal cured to the flat face 23 of rail 11. These strips when interlocked complete an S- shaped weatherclosure as shown.

'l he head 5 is similar to the jambs 2 and 3, but its parting ridge 54 is narrower than the.

strip 53 se ridges 25 so as to allow clearage for strip 52 of the lower sash, when said sash is raised.

I Angle strips 55 and 56 are preferably al-liXed to the head shown, to close againstthe flanges 25 of the top rails when a'sash is,

raised. V

The sill 4 comprises a bent metal shell open at the bottom and preferably filled with concrete indicated by 57. Its upper face has an exterior inclined portion or shed 58. A l sash flanges to retain the sash; and clamping I horizontal ledge. 59 runs along its inner edge and partly overlies tho shed 58. An angle strip 60 is preferably secured to ledge 59 to face against the flange 25-01 the lower rail of sash 7. This flange may be provided with a depending weather strip 61 passing below ledge 59.

The various members of he frame may be joined by any approved means, known to the art, as will be understood.

The particular sash tainstruction described herein is covered by the claims in my (0- l pending application, Serial No. 356,553,-filed February 9, 1007.

It is to be understood that this invention is not limited to the embodiment shown and; that many parts may be modified within the scope of this invention: flllllltllllOYO that many individual elements and combinations of elements would be still within the scope ol' the invention whencombined with widely varying window construction.

This invention comprises features which greatly cheapen window construction of the class described; work a great economy in the maintenancev of the completed structure; while, as well, the construction possesses the qualities of durability and efficiency.

Having thus described my invention, 1
