Patented Feb. 3, 1931 PATENT oFFicE CHARLES GABRIEL OHAR-A, OF NORRISTOWN, PENNSYLVANIA CAST-METAL wrimow FRAME Application filed October 17, 1929. Serial No. 400,173.

My invention may be employed with particular advantage in what are known as casement structures and particularly for cellar windows, and as hereinafter described my invention is adapted to be used in either frame, brick, or other masonry buildings.

It is the object and effect of my invention to provide a window frame formed of four primarily separate members of such construction and arrangementthat each may be cast of suitable metal, such as iron, and assembled in rigid relation with each other to producea frame at less cost than an ordinary wooden frame of the same size.

Of course, numerous attempts have been made to produce window'frames of cast metal but the construction and arrangement thereof have been such as to necessitate machining or other costly facing operations at the regions thereof which must be brought together to form joints between the several members thereof. Therefore, an object and effect of my invention is to provide a cast metal frame so constructed and arranged that it is unnecessary to machine or otherwise face the portionsthereof at the joints. Moreover, a considerable item of cost of such structures of the prior art is incident to the provision of hinge members and fastening means. Therefore, a further object and effect of my invention is to so construct and arrange one of my improved cast frame members that sash hinge elements may be provided thereon of tough wrought metal at minimumcost for material and labor in assembling the same, and to provide upon the opposite cast member of said frame, sash fastening means cast in unitary relation therewith and at minimum expense.

As hereinafter described; the regions of the members which are to be joined together are provided with small projections in groups in such spaced relation that the two members forming the joint may be drawninto and retained in rigid relation by a single screw.

My invention includes the various novel features of construction and arrangement hereinafter more definitely specified.

In said drawings; Fig. I is a front elevation of a cast metal frame, hingedly connected with a wrought metal sash and having fastening means for the latter in unitary relation with the frame. r

Fig. II is a rear elevation of said structure shown in Fig. I.

FigIII is an end elevation of said frame. I Fig. IV is a Vertical sectional View of said frame andsash, taken on the line IV, IV in Figs. I, II, and III.

Fig. V is a top plan view of said frame. F Fig. VI is an inverted plan View of said frame.

Fig. VII is a fragmentary inverted plan View of a portion of said upper frame member showing the construction and arrange ment of the hinge member.

Fig. VIII is a fragmentary vertical sec tio-nal view taken on the line VIII, VIII in Figs. II and V, and showing the construction and arrangement of the frame and sash hinge members.

Fig. IX is an end elevation of the top or lintel of said frame. 7

i Fig. X is an end elevation of the bottom the frame j amb members, showing the location and arrangement of the groups of three spacing projections serving as bearings for the horizontal members of the frame.

In said figures; the rectangular window frame 1 is conveniently formed of four cast channel bar members; to wit, the lintel memher 2, sill member 3, and opposite vertical jamb members 4: and 5. Said members 2 and 3 are'respectively difierently constructed and arranged, as hereinafter described, but said members 4 and 5 are precisely alike in construction and arrangement, altho disposed in reversed relation.

Said lintel 2 has a longitudinal web 7 inclined downwardly from the front to the rear of said frame 1, and has upwardly extending longitudinal flanges 8 and 9 respectively at the front and rear edges thereof, and the downwardly extending longitudinal flange 10 and a screw threaded'socketl betweensaid sockets 18, fltted to hold the capscrews 20. Said lintel member 2 also has'pairs-of downwardly extending flanges 21 upon the under side thereof in said recessll in such spaced relation as to embrace between. :them the.-

hinge members .223 which,..as=shown in Fig VIII, are angle plates of wrought metalwhich are held between respective pairs of;

flanges 2-1 by respeotivesingle screws 24.

Said sill member is oppositely counterpart to said lintelmember and. similarly constructed and arranged, including a'longitutending longitudinal; flange intermediate of said flanges 28 and 29 forming a sashrecess-31. However, .-said sill member d-iifers from said lintel' member in that it has. no hinge means but has, intermediate of its length, a keeper socket flange 33 forming-awedge-shaped slot 34 for sash fastening means, as hereinafter described.

Said sill member-3' has oppositely counterpart flanges 36 and 37' extending vertically at opposite ends thereof between said flanges 28 and 29 :and forming recesses 39 and 40;in which the joints are made, as hereinafter described. Said sillf 3has, at each of the opposite endsthereof, two sockets 41fitted toreceive' projections on: the jamb members,. as hereinafter described, and a screw threaded socket 42 between said sockets 41, fittedtb hold the cap screws 44.

Each ofwsaid j amb-members 41and5 (which, asabove stated, are precisely alike, but disposed in reversed relation in the frame 1,); has a longitudinal web46 inclined inwardly, toward the center of the frame, from; the front to the rear thereof, and has outwardly extending flanges'47 and 48 respectivelyat the front andrear edges thereof, and, the inwardly extending longitudinal flange. .49 intermediate of said flanges K and 48 and forming the sash. recess 50..

Each of said: jamb members-4 ;and.5. has oppositely counterpart. verticaliy extending flanges 52 at respectively opposite ends thereof, which flangesareioflsetoutwandly to form recesses 53' for reception. of the ends of said lintelr2 and sill 3'and', as shown in Fig. XI, each of said flanges: 52 is provided. with :a hole ;54-for engagementwithzeither aiscrew'20 7 extending from the lintel' 2,..or a screw 44 extending from the sill 8. Each of said j amb flanges 52 is also provided with a group of three projections in such spaced relation with respect to said screw holes and screws that i without planing orot'herwise facing or ma chiningsaid projections or the opposing surface withwhich they come in contact.

It is to be particularly noted. that altho the flanges49 on the oppositejamb members 4eandl5.extendin thesame plane .-as.the flange 10.0n thelintel member 2, the flange 30onthe. sill-member 3 is offset closer to the rear face of. the frame 1 and-stops short of the opposite ends of theframe, so: as to peranitv drainage of water from said jamb flanges 49v to.

flow down-the sill inclineand. be discharged.

at the outer face of the frame 1. If. such a Weathering arrangement of the flanges; 30 and 49. were not provided, the rainwater aforesaid would. be trapped and tend to flow.

down into the sashrecess .31.

Thesash 6.0 isconveniently formed. of'sections of wrought metal. bars respect'ivelyv forming the top rail 61, bottom rail 62, opposite end stiles 63, and mullions 65., all of which are welded together in rigid relation andform a plane flange 66 which is continuous. around said sash. and adapted to fit againststhe rear plane face of said window. framel. The flange66 on said top. rail. 61' has slots 67 to receive. said; hinge plates 22. The .bars68 above said slots are offset. rearwa-rdlyso that they form pivotalconnections with said/hinge plates 22.; so that said. sash 6.0 may be. freely swung rearwardly. without interference of its topflange 6.6 by contact with. said window frame 1. t may be observed that the construction. and. arrangelions whichare of T-shaped cross-section,

so that the sash is adapted to holdthree panes of glass which aneretained therein by fillets of. cement 74'.

Said sash: 66 has fastening means including; the lever latich- 6 which isconnected frame, in which case the sash would.

therewith by the rivet pivot 77 so that its arm 7 8 may be turned downwardly into the wedge-shaped slot 34 in the socket 33 on the window sill member '3 to press said flange 66 against the rear face of said win dow frame 1. v

I find it convenient to provide said with a weathering member at the bottom thereof comprising the channel bar 79 which is rigidly connected with the bottom rail of said sash, conveniently by spot welding the same. As indicated in Fig. IV, said channell bar 79 fits in the sash recess 31 in the sill member 3 of the window frame 1 in close relation therewith, and the double flanges on said bar 79 serve to check the flow of any moisture inward with respect to said frame and thus prevent the same from dripping over the inner face of the subjacent wall.

' I also find it convenient to extend sai flanges 48 on the jamb members 4 and 5 o the sash frame 1 so that they overlap th wooden or masonry setting in which .iai frame is placee, and said flanges may be p vided with holes 81 for means such n or screws for rigidly securing said frame in said setting. However, if the setting inasonry, said frame 1 may be otherwise secured, for instance, by flowing mortar or other cementitious material into the recesses exterior to the inclined web f anges '5', 2?, and 46 on the respective frame members 2, 3, 1-, and 5.

Altho I have described an embodiment of my invention in a position in which it be employed as acellar window, of course, it may be otherwise positioned, for instance, either of what "i have termed the b members e and 5 may be the top or bottom of the hey n on a vertical axis and, of course, other fo? of sashes may be used in connection 'w window frames constructed in accordance with my invention.

Alth'o the sockets 18 on the lintel and the similar sockets 41 on the sill are useful in that they laterally engage the projections 56 and prevent relative displacement of the frame members at the joints thus engaged even if the screw 20 or the screw 4 e omitted at such joint; such frame members as above described may be held together in rigid rela tion by a single screw at each joint without the proviison of any such sockets; the grou of three projections 56 and 57 surrounding such screws being drawn into stable relation with the opposing member, by the single screw local to said projections.

Therefore, I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention, as defined in the appended claims.
