FIREPROOF SASI-I FRAME.

.Application` led November AThis inventionrelates to newv and useful improvements inl sash frames, generally, but more particularly relatesjto improvements in such frames adapted to ybe mounted in masonry or concrete walls such, for instance, as building foundations.

An object of the invention is to provide a .iirefproof sash frame constructed of concrete or masonry and having a reinforcing means interposed therein. A l

A further :and more specific object of the invention is to provide reinforced concreteA sash frame having a 4metallic skeleton frame interposed therein, and the marginal edges of the metalframe substantially concealing `the opposed edges of the masonry and also providing a seat for the sash.

The particular object of the invention, therefore, is tofprovide an' improved lireproof sash frame.

Other objects of the invention will appear from the following description and theV acn companying drawings and will be pointed out in the annexed claims.

in the accompanying drawings there has been disclosed a structure designed to carry out the various objects of the invention, but it is to be understood'that the invention is not confined to the exact features shown, as various changes may be made within the scope of the claims which follow.

ln the accompanying Adrawings forming part of this specification,l

in Figure 2. and comprises the opposed hori-L zontal frame membersv and 8 and the upright end members 9. These members are preferably of angled cross section and may be formed of sheet metal, and suitably secured together at their ends byl such means as plates 11. The plates 11 are preferably electrically snot-welded to the members V7,

8 and 9 or, ir desired, they may be riveted thereto, thereby providing two rectangular frame sections. These two frame sections are spaced apart in aarallel relation and are tied together lby means of ties Vor straps 12 and 13 preferably arranged in staggered relation as shown in F igure 2. The outer ties 12 are terminally provided with right angled extensions 11i adapt-ed to engage the inner faces of the outer flanges 10 of the frame sectionsto provide means for suitably sec ring them` thereto by such means as` welding or riveting. The' inner ties 13 are similarly secured to the outside faces of the intermediate webs 2O of the framemembers 7, 8 and 9. The above described structure thereby provides a very substantial and rugged skeleton frame around which :the

concrete is molded to form the frame shown 1n Figure 1. lnwardly projecting vflanges 30 are also provided on the frame members 7, 8 andA 9 to providethe abutment seat for the sash as shown in Figures 1, 2 and 3.

In constructing the frame, the mold in which the concrete is poured to form the frame is preferably constructed in such a manne as to provide an inwardly extending portion 15 which is preferably centrally located in the frame and is interposed between the i1 vardly projecting flanges 30 to provide a backing therefor as shown in Figure 3. lt will also be noted by reference to Figure 3 that the outer flanges l0 of the metallic frame members 7, 8 and 9 are exposed in the completed sash frame, thereby protecting the corners of the concrete against possible injury, and also providing a recess or seat to receive the sash 16.

A longitudinal groove 17 may be provided in the face of the raised portion 15 at the bottom of the sash frame as shown in Figure 1. Transverse grooves 18 lead from the groove 17 tothe outer edge of the portion 15, thereby providing means for draining the water to the out-side of the sash frame, and thus preventing it from entering the bnilding through the joint between the A:ash

and the sash trame. the edges or the lower 'i5-range 3G in alinement with the grooves 1S, shown in Figure l.

Sash-supporting hooks 19 are preferably provided in the upper portion or the sa trame adapted to support the sash as sho particularly in Figures l an( l 3. 'hese hooks may be 'formed ot strap iron extending through the entire trame fffliown in Figures Q and 3 or, it desired, each hook may be independently constructed and have its inner end secured to the frame member T, after which they will be securelyT held i1. placeV as a result ot beine embedded'in the concrete as shown in FiC ='e 3. The ab described sash trame thus provides a il prooiZ structure of very sturdy and rugged construction. lts general lorm also similar to that ot' the standard wooden 'frames now used for similar purposes, and it may therefore be interchangeably used with such frames. rlhe skeleton rein'iio-rc'ng trame shown in Figure Q provides a very substantial foundation upon which to supportthe concrete or masonry. rThe construction ot' this frame is also such that it may be manufactured at a. minimum cost, which`r considered with ther cost olf moldingv the concrete around the skeleton trame, will not be prohibitive, thereby providing a sash frame well adapted tor use in the erecti ott building structures. Y

Figure 4C illustrates a modified construction wherein the horizontal reinforcing' trame sections 2l and 22 and the upright sections 23 are 'formed out of sheet metal, and are suitably oined together at the corners by means of the plates 1l, in a manner similar to that shown and described with reference to Figure 2. Apertures 24 are provided in the metallic frame sections 2l, 22 and 23 to permit the concret-e to flow therethrough as shown at 25 in Figure 4. so that the inner raised portion l5 of the sash trame will be securely tied to. the outer port-ion oit the frame. The seat 26 for the inner sash is preferably inclined as shown so that any water entering the scat from the outside ot' the building may flow through suitable drain ducts 27, leading from the inner seat 2G to the exterior of the sash `frame (see .Figure 5).

Figure 6 illustrates another modied construction wherein thev metallic reinforcing frame substantially covers the entire inner surfaces of the sash trame. "in the construetion here shown, the inner seat 26 similar to that shown in Figure 5, and suitable ducts (not shown) lead from the seat 2G to the exterior of the 'trame in a manner similar to that shown and described with reference to Figure 5. lt will also be noted in this construction that the raised portion l5 or" the frame, which provides the abutment seats for the inner and outer sash, will be entirely covered by thel sheet metal reinforcing trame, thereby concealing the concrete or masonry forming the major portion of the sash trame.

Having thus 'described my invention, what I' claim as new and desire to secure by Letters Patent is:
