LARS CHRISTENSON, or NEwYoRK, N. Y.

HOLLOW VFIREPROOF To all whom it my concern.-

Be it known that I, LAas CHR srENsoN, a. "citizen of the United States, residing at the borough of Bronx, city of New York, county of New York, and State of New York, have invented certain new and useful Im rovements in Hollow Fireproof Doublelazed Windows, of which the following, taken in connection with the accompan ing drawings, is a full, clear, and exact speci cation.

This invention has relation to that class of windows wherein the rails and stiles are made of sheet metal, and particularl to the form wherein double glazingor doub e lights areemployed.

. he principal objects of my invention are to provide or produce a strong, durable, and reliable window of theclass named, whlch may be easily and cheapl manufacturedand conveniently and secure y mounted' in place for use in a wall or partition wherein it will afford the'desired lighting and. fireproof capacities, ample provision being1 made for venthe interior of the sheet-metal portions, the

window bein made up. of several distinct panes or pane s.

To accomplish these objects and to secure other and further advantages in the matters, of construction, operation, application, and use, my improvements involve certain new and useful peculiarities of construction and relative arrangements or combinations of parts, as will be herein 'first fully described and then pointed out in the claims.

In the accompanyingdrawings, forming part of this specification, Figure 1 is a front elevation of a window constructed andar ranged for operation in accordance with my invention and involving m'y'im' rovements, the same being shown as inclu ing several e-hinged section incorporated in the window, the win- .dow being represented as finally mounted in l or partition.

The

panels of any desired number and 0' any required size, and the panes maybe arranged in the window as may be desired, following the general principles ofconstruction herein referred to. tended to be mounte 'in any wall or artition of masonry or other character which is represented at A. When the window is employed in an exterior wall, as it may be, the exterior portion is preferabl made so that the panes are not removab e from the exterior; but when it is employed in an interior partition it is preferred to make both faces of the window of similar construction, because both faces are then equally accessible, and the two faces may be advantageously made alike.

B B represent the glass panes, which are secured in the window and which may be of I prefer to employ what is commonly'known' as wired glass, the same affording-Fa better protection against the effects of o; but plain or other lass without the wire may be employed, if so esired. The panes are double throughout the window, and they are separated by a suitable distance, de-

pending upon the width of the strip or stop em lo ed etween them.

s t e window itself isintended to bepermanently fixed in the wall or artition it is desirable to hinge one or more 0 the panels so that 'an opening may be obtained through the window for ventilation and other purposes. While the hin ed portion may be le panel, fhave chosen to illustrate two a acent" panels h' ed so that 'they will close one 'a ainst the ot er,

Further,

it will be observed that the construction is' such as to make the meeting faces of the hinged portions alike, which simplifies and 5 cheapens the manufacture.

The metallic pieces are rolled or bent and fashioned of sheet metal by suitable machinery and in strips of any desired length,

' to be afterwardcut and assembled.

The construction of one 'of the hinged stiles D is illustrated in Fig. 3. I Thesestiles are provided with recesses, as a a, to receive the glass, and their front and 'back faces are bent and doubled, as at g and h, and interlocked or beaded with a vertical piece, as i.

stile, in which latter there is a recess lg to receive the doubled portion g. The door swings on its hinges ,ithe doubled portion 9 being suitably bent, so as to clear the ad'acent portion 'of the stile on which the door is hung. It will be seen' that one ortion of the adjacent stationary stile reaches beyond the corresponding face of the door and that the arrangement is such as 'to revent a draft or ourrent of air between th adjacent stationary stile. When the double doors are employed, the hinged stiles are similarly made, although oppositely located, and this for obvious advantages in the manufacture. Y 1

In Fig. 4 the two faces of the Window are shown as of similar construction. E represents the end stile, the same being composedof two pieces of sheet metal. The main portion of this stile is bent, as at] Z, to form recesses for receiving thesto s F F and at m are seated and retained in place by the stops FF. This portion is also angularly bent, as

' at n, to form a parting-strip between the two panes, the same determining the distance of either side of the frame or the previous One of the bin e-plates 7c is riveted to the eX- e hinged door and the carried back and beaded, as at 0'0, with the end stripor'plate The latteris doubled, as at p, at or near 1ts central part to form a projecting flange which is intended to be emeddedin the material of the wall or partition and to furnish a secure anchor for the'window. Under this construction the stops F F may be removed and the panes inserted from window. This construction is principally intended for use in inside work.-

For exterior windows it is preferred that the panes shall be inserted and removed from the lnside of the window only, and the construction shown in Fig. 4 provides for this. In this form the parting-strip 'n" ismade removable,and the panes are secured in place by this strip and by a single removable stop F," which ma be the same as the stop F in gure'.- The main portion of the stile in this form is preferably bent outward, as at E, to form-a mar inal weatherdnoldin and it is then carried sick and jointed with the back plate G", as at .p', to form a projecting flange for entering the masonry or other material of the wall, and this back plate is beaded with the'r'nain portion, as at 0. p In this construction in order to stiffen the stile it may be desirable to employ interior angular strips, as indicated by the dotted lines at I although if the metal of'the window be sufcientlyst ifl this bracing may be omitted.

In Fig. 5 the top rail is indicated at H, and it is shown as formed to correspond with the construction shown in Fig. 4' the removable arting-strip' n and the removable stop F heing continued. The general form of the to rail is merely a continuation of the 'end st] e, and so far as its outline is concerned it need not be more specifically described. Instead of being made to correspond with Fig.

4* it might be made on the lines indicated in Fi .4. a

i corresponding interior horizontal rail is shown in detail at I in Fig. 6, a removable stop F and removable parting-strip n being employed on the under side of this rail and the under side being bent to form angles and recesses of' the same general character as *those in the lower face of the top rail. The

upper part is, however, bent to form a stationary stop F and a stationary partingstrip a, it being unnecessary to provide removable strips or stops on one margin of the panel, for the panes may be inserted at one edge in the grooves or channels provided for them and afterward secured at the other three margins. The rail so formed is easily made in one piece. Y

K, Fig. 7, represents the lower horizontal window-rail except the portion which constitutes the sill for the hinged doors, and this also is conveniently made in one piece, as shown. Its'top face is bentto formthe stationary stop F and the stationary parting? strip a, corresponding with the upper face of one of the interior horizontal rails- Its interior front face is plain; but the exterior front is recessed, as at r, and its bottom is referably inclined slightly, as at s, so as to orm a proper seating on the wall and provided with openings, as at t, which 0 emngs'will admit .a portion of the material 0 the wall to assistin anchoring the window. I

Interior braces for the lower rail-may be supplied whenever necessary. L represents such a brace, the same extending from one corner up to the wall of the channel for the inner glass and serving to stiffen the structure in a manner which will be apparent.

It is desirable to provide for a circulation of air through the metallic parts and between the panes 0 glass to insure against overheating and conseqluent damage, which may be unnecessary. therefore perforate the ma-.

terial of the lower rail, as at v and w, at suit-- able intervals, which perforations will admit air from the exterior.. A current of air passes up through the hollow metallic portions and out at corresponding perforations in the top rail, as at v; the lower rail wil enter between the double panes, pass up through suitable perforationswhich are provided for the purpose, and finally enter the top rail and escape there-- from through the perforations 1).

The construction of the. larger interior stationary stiles is represented .in Fig. 8 and of the smaller in-Fig. 9. These stiles are so constructed that they will join with the horizontal rails above and below them and present a harmonious appearance with those rails. In the form shown in Fig. 8 the stile is composed. of two parts, the projecting margins of one part entering recesses in the other, as shown at 13 13, the same form of removable partingstrips n and of removable stops F being employed as in previous figures and the parts of the stile being bent to form angles and recesses to accommodate the panes and other arts, as ex lained with reference to previous gures.

nFig. 9 the parting-strips n are held in place by the panes, and the removable sto s F F are made continuous with the upri t member and held in place by a peculiar stening. The exterior or weather molding 14 has interior ledges on each side, and aseparate piece 15, made by doubling a strip of sheet metal, has exterior flanges 16 16, which engage the interior ledges on the weathermolding, as indicated. A removable screw, as '17, passes through the bridge, which unites the sto s F F and enters the interior piece 1.5. hen the screw 17 is tightened or finally seated, it draws all the parts to their proper location and holds them securely in place.

A ortion of the air-current in 18 represents that portion of the horizontal rail which is located above the o ening closed by the doors. (See Fig. 10.) ts upper surface corresponds with the remainder of the horizontal rail; but its outerface is preferably recessed, as at 19, and in this recess is a small perforation, as at 20, to rovide for the entrance of a current of air w 'ch passes between the upper panes through a perforation, as at 2-1. This portion. of the rail is referably made of a continuous piece proper y bent and havingits margins beaded together or interlocked, as at 22, where the interlocked parts are bent down to form a sto for the door to close against.

he door-sill 23 corresponds with the lower part of the lower window-rail, being bent on the exterior to form an angle 24 and on the top to form a recess 25. The lower rail of the door 26 is fashioned to correspond somewhat with the upper part of the lower window-rail, but having a downwardly-projecting'part27,which,togetherwiththe si ,forms a recess 28. Air enters thisrecess and asses up through a perforation 29 into the ollow door-frame between the panes and out at the top through suitable perforations provided in the upper rail of the door-frame. The bottom plate of the lower rail 26 is bent to form a projection 30, which enters the recess 25, and the inner face of this lower rail extends down, as at 31, to close against the adjacent face of the sill, and it is then bent back and interlocked with the margins of the plate 32, which forms the bottom of the lower rail of the door-frame.

The upper railjof the door-frame is composed of a central piece 33 and outside a plied moldings .34 and 35, each preferably made of a single piece of sheet metal. The top of the iece 33 is bent or doubled to form slight angles for the reception of the moldings34 and 35, and the bottom is bent so as to form the parting-strip between the two panes. The

moldings

34 and 35 secure the two anes in place, the upper part of the mold ng 34 being made to project horizontall as at 36, to strike against the portion 22 of the part 18. The outside face of the molding 35 is carried up and bent, as at 37, and located so as to project beyond the lower face of the part 18. The projections'36 and 37 operate to stop the door at the proper position when it is closed and prevent a draft of air from passing betweent e top of the door and its casing, as is desirable, to exclude dust and to secure a proper fitting of the door.

The perforations in the iece 33 and the molding 34 permit the circu ation of air from between the panes to the exterior, as will be readily understood.

The a plied parts of the metallic framing for the oorsand window-panels are secured parts being combined at-the desired points by making a sma piece into which their points are to enter. In .Figs. 11 and 12 I have illustrated two forms of these slits or Openings which may be made for the urpose. At 38 the opening is made in. angu ar shape to receive the end of the screw, and at 39 a small circular opening, with straight slits extending therefrom, is shown.
