To all whom it may concern:

Be it known that I, MI LARD FfHAM sLnY,

of Brooklyn, in the county of Kings and State of. New York, have invented a certain new and useful Improvement in Fireproof 'Windows and I do hereby declare the followingto be a full, clear, and exact description of the same, referencebeing had to the accorn panying drawings, forming apart of thisspecification, and to the figuresand letters of reference marked thereon.

i This invention relates toimprovements in metal fireproof windows of that type wherein the several parts are usually formed of sheet metal, the objects of the invention being to provide a window the partsof which may be shaped up in dies and when assembled will resist to the maximum any tendency to separate or warp under the influence of heat or sudden and extreme changes in temperature and which will also offer the maximum rebinding or indentation at salient points.

Further objects of the invention are to provide a window having tight or weatherproof joints both between the relatively away through a window embodying the presfixed parts and between the relatively mov- 'able members constituting the whole structure.

Referring to the'accompanying drawings: Figure 1 is a vertical section, partly broken ent improvements. Fig; 2 Is a horizontal section, on line 2-2, but on a somewhatv larger scale and with intermediate parts broken away, the plane of the section being through the upper half of the sash. Fig. 3

is a similar section, line 33, through one half of the window. Fig. 4 is a detail sec tional perspective of a part of the casing and upper part of a sash. Fig. 5 is a detail vertical section through the sill' and sashin proximity to the muntin in one sash, part of the latter also being in section. Fig. 6 is a perspective view of one corner of a sash, the

parts being separated and broken away to show the manner of assembling. Fig. 7 is a vertical section through the sill and base of a mull'ion or munnion. Fig. 8 is adetail horizontal section showing the preferred means for supporting thetransom bar. Fig. 9 is a detail of the bottom rail of the sash.

Like letters of reference in the several figures-indicate the same parts. v As shown in the drawings, the frame for the window is made up of a sill A, jambs Patented Dec. 24, 1907;

B head or lintel 0, center p'ostor mullion D andtransom bar E', but it willbe understood that any-number of posts or mullions may be employed, or none at all, depending upon the width of the window, so too, while upper and lower sash openings are formed by. the transom bar, the said barmay be omitted, particularly if the windowis short vertically, and only a single sash is desired.

The sill A is formed up of sheet metal by substantially straight longitudinal folds and bends,-thu s 0n the inner side of the window the sheet metal is folded closely around an angle iron core bar A, so as to embrace the outer face and both edges of theiron. Where the sheet metalfolds in under. the upper or outer edge of the angle iron it forms a recess a into which the edge of the sash passes to form a tight joint as will be p'resentl exlained. From the recess a the metal ormwardly inclined riser a and at the outer edge the metal extends downwardly in the form of a skirt a, the table a and skirt a overlying an angle bar A the flanges of which preferably form an obtuse angle as shownclearly in Figss'l, 5 and 8. The edges of the sheet metal forming the sill are clamped tightly around the angle irons A and A respec- Y tively, thus the salient edges of the sill are strengthened sufliciently when backed by the cement setting to withstand any stress .short of such as would completely destroy the Window.

-- The three exposed faces of the jambs B are i preferably formed of two pieces of; sheet metal umted on the inside of thecasing by a folded seam at b intowhich seam one edge of a weather strip or channel iece F may be. folded throughout the lower alf of the sash, as shown in Flg. 3. The inner and outer faces of the jambs are madewith relatively deep vertical channels G, G respectively, While the intermediate face G? is substantially fiat and at right angles to the plane ofthe sash. The formation of the channels G and G in figuration which'is adapted to receive and retain a rectangular core bar H one face of whiclrfitssmoothly against the inside of. the intermediate face G of the jamb and the a the faces of the jainb gives an internal conedges of which fit into and support the edge or projections forming the outer sides of the said channels, thus the sheet metal of the jambs is firmly backed at salient edges to resist deformation through any cause.

The head or lintel C, Fig. 1, has its outer, inner and intermediate sldes formed of a single piece of metal, the intermediate face being formed with a channel 0 for the reception of the edge of the sash, said channel opening inward so as to be entered by the outer edge of the top rail of the sash as it moves outwardly to closed position. At the inner side of the channel 0 the face inclines in a plane substantially parallel with the water tables of the-sill and transom bar whereby a sash pivoted on a horizontal axis will close tightly at top and bottom all as shown clearly in Fig. 1. V

Where a wide window or one requiring more than one sash side by side is desired, the casing is made of suflicient width to admit one or more mullions or vertical intermediate parts each intermediate face of which will conform to that of the jambs. Each mullion is made up preferably of two pieces seamed together at d, (I, such seams corresponding tothe seams b in the jambs. The mullions also have channels D D corresponding to the channels G G in the jambs with internal core bars D forming the backing for the salient edges. At top and bottom where the mullions join the sill and lintel the outer and inner faces are preferably extended and doubled back around the edges of the lintel and sill, as shown clearly in Fig. 7, whereby the mullions will be held firmly in position, but it will be understood that additional fastening means of usual or preferred character may also be employed when desired.

In fireproof windows of the character to which the present invention relates it is devertical sections by transom bars.

sirable to make use of sash pivoted on horizontal axes so as to tend to close automatically if released, and it is also desirable that the sash should be of restricted height and hence it is usual to divide the casing inZo s shown in the accompanying drawings, particularly in Fig. 1, a transom bar E is employed. This transom bar is preferably made up of two pieces of sheet metal seamed together at e e, the seams forming the outer walls of recesses into which the edges of the top and, bottom sash fit when closed. The

'top and bottom faces, of the transom bar conform essentially to the form of the cenjambs and mullions.

tral parts of the sill and lintel so as to fit the edge faces of thesash accurately and with an 7 outward inclination to prevent the entryof water. A flat or rectangular core piece E forms a-filler for the transom and gives the same great rigidity and strength in addition to affording a ready means whereby the ends of the bar may be firmly fastened to,the

The preferred connection is shown in detail in Fig. 8, where it will be seen that dowels ortenons E connect the ends of the rigid core E with the cores H bed the casing in cement which may be pouredor otherwise placed in the cavities between the wall and casing, as shown at 'i t. In most instances it is desirable to leave the jambs and lintel hollow and for this purpose recessed fillers K are seamed to the edges of the jambs and-lintels, the recesses in said plates, as shown in Fig. 2, serving to receive cement to form keys of greater size for retaining the casing firmly against displacement.

The sash, which is of special design for cooperation with the casing described, but which embodies features common to both casing and sash, is formed with sheet metal top, bottom and side rails, wrapped or folded about core pieces for uniting the parts and giving additional rigidity.

The core pieces M of the sash are of substantially rectangular section, one being provided for each rail and with one end M bent up at right angles to enter the adjoining rail as is well illustrated in Fig.6. The sheet metal N is bent closely around the core pieces, the edges at N on one side of the core piece being bent out at an angle to formthe channel for the lass between them. Between the parts forming the side walls of the glass channel a U-shaped channel iron 0 is located and held in place by the inturned extreme edges N of the sheet metal covering, thus not only are the edges of the covering prevented from spreading, but the walls of the glass channel are made very rigid.

The bottom rail of the sash should have an apron to overlie the riser a of the sill and for this purpose the sheet metal cover of the bottom rail is extended at one edge of the core and bent downwardly as shown at P, in Fig. 9. In this figure and Figs. land 5, it will also be seen that this bottom rail is inclined to the plane of the sash and consequently the walls of the glass channel are inclmed to the plane of the core, one side of the channel being made somewhat longer than the other to bring the edges up to the same level. At the end wherethe core is bent up at right angles one edge is cut away as at P to permit said end to enter the side rail correctly.

The preferred construction of side rail for the sash is shown in Fig. 4;, wherein it. will be seen that the sheet metal cover is in two parts seamed or with their edges folded together at extends from the pivotal center to the top or I bottom of the sash, thus as shown, it extends tothe'top of the sash and is located on the innerside. The joint between the other half ,of the sash and casing is bridged by the strip before referred to and shown particularly m Fig. 3. I

To insert the glass S, its upper edge ispassed up into the channel at the top of the sash, which channel is usually made somewhat deeper than at the sides and bottom,v

(Figs. 2, 3 and 5) is composed of two parts,

the part on the outside embodying a sheet metal strip or bar having side flanges T with the edges turned back'to rest against the glass and a central channel T in which a solid core bar T is permanently mounted and held by rlvets or similar fastenings. V

The part of the muntin on the inside of the window is of somewhat similar formation save that the flanges t are bent closely arounda wide flat core t and the edges 25 of the strip are turned at right angles to the core so as to pass in between the adjacent edges of the glass. Screws U passing through the inner half of the muntin and screwing into the'core bar T serve to clamp the two parts firmly together. At the bottom of the sash the central part ofthe outer half of the muntin preferably extends down over thewalls of the glass channel as shown at U in 40 Flg. 5, while the inner half is,cut away at a somewhat higher point to avoid contact with the sill and the outer face of the channel is bent in as at U in said Fig. 5 to give a finished appearance.

The sash are mounted so as to swing inwardly atthe top and outwardly at the bottom'and for this purpose hinges are provided of such form that they maybe readilysecured to the sash and easing or mulli'on.

The upper leaves V of the hinges are preferablyad ustabIy secured to the side rails of' P the sash by bolts 11 passing through slots in the hingeswhilethe upper and lower leaves.

- embodying bar angle iron cores-1n the lnner of the hinges are secured together by pintle bolts V said bolts being adapted to pass way through the mullion'br casingand to be held in place by cotter. ins or similar fastenings at the ends. Said" ower leaves of the hinges are adapted to fit in the channels G (see Figs.

6b 2 and 3) and in addition may be securedby rivets or bolts as usual. One hinge of each alr is provided with an extension W on each- 1 eaf to one of which a rod W is loosely secured, and adapted to be adj-ustably' clamped to the other by a thumb nut and screwW whereby the position of the sash may be controlled.

The pivotal axis of the sash is so located that if entirely free, the windows will automatically close in order to automatically freethe sash should fire occur in the'vicinity of the window, a washer X, fusible at low temperature, is interposed between the thumb nut and rod W. If the washer melts the rod is instantly freed from the clamp and the window closes. In both the mullion and jambs small openings such as indicated at 7 in Fig. '1, are preferably formed at top and bottom to afford ventilation and drainage.

When closed as shownin Fig. 2 it will be .noted that the outer edges of-the. sash are substantially flush with the edges of the walls of the channels and as a result storm water will be blown into the channels, rather than between the sash and casing, the channels forming, in effect, ducts for protecting the parting openin and conducting all storm water down'away from the sash. Having thus described my invention, what I- claim as new and desire to secure by Letters Patent, is:

1. A fireproof window embodying a casing formed of sheet metal and internal longitudinal core pieces of flat bar metal along the salient edges held in place by the folds and bends of the sheet metal passing around both edges of the bar.
