v Intview. on the. foregoing it. is. the. primary object ofthis.

invention: toA simplify the installation of window wall structures, and alrelatedobject is to enable such mounting.y

tez-be".-accoinplishedrquickly and easily by one workman.. Another important; object of the invention isY to provider awell-typez basementwindow structure, wherein the windonn frame and well structure embodies. inter-related frame in'positions such that the` framemay be mounted,

inthefconcreteiforms, and in such a way that such fasteningeiemehtsfare: subsequently exposedA and may function inisecuringthewell member in place.

@ther and further objects. of the present invention will.

be. apparent from. the following description and claims, and are illustratedin the accompanyingl drawings, which, by way of. illustration, show a preferred embodiment or ther present'k invention and the principles thereof, and what is; now considered to be the best mode, in which to apply these principles. Other embodiments of the invention embodying; the same or. equivalent principles may be used and structural changes mayl be` made as desired by those skilled in the art without departing from the invention.

In the drawings? FEGUREn l' is a' fragmentary perspectives viewl ofT a welll-type" basement window; structurev embodying the features ofthe invention;

FIGURE 2 is' a vertical sectional view taken through the window frame whileit'is' in position in the` concrete forms that definethebasementwall;

FIG-URE 3 is a horizontal sectional View taken substantially along the line 3 3 of FIGURE 2 and showing ICC For purposes; of disclosure the inventionA is hereiui illustrated as embodied in awell-type basement window ini'- stallation 10' inwhich a metal window frame 11 is cast in place in aconcrete basement wall' W, and with an arcuate` corrugatedrsheetrmetal well 13- spanning the window opening and'l secured in position along the opposite outside. vertical edges, of the window frame 1l in such a way that, the well. 13 may be readily and easily secured in position. by but one workman at' any one of a plurality of levels. according to; the proposed outside grade level.

The window frame 1,1 in the present instance is'. of. the wide or full wall-Width type so that it completely spans the spacebetween the inner and outer forms i4 and 15, as shown in FIGURE 2 thus to eliminate the needfor special window-forms for definingv parts of the windowf opening. Thisv full width* of theV form of the frame 1l is: desirable andlconveniennbut it is not absolutely essential. to the presentinvention, because, as wili become appar:- ent, the cooperation between theframe 1i and the well 13.- is accomplished at the-outer vertical edges of the frame il.A

Thus, the window frame 11 is. formed from sheet metal to provide ahead` 11H and a sill 11S that are connected by vertical jambs 1-1J- and these membersV have appropriel ate shoulders formedon their inside surfacesto cooperate withv awindow sash 17 and a screen or other supplemental. sash 18. The particular form aud arrangements. ofA the. sash elements is immaterial insofar as the presentinveuf tion may be concerned.

Under the present invention, the' outer edges of the jambs 11] have outwardly directed flanges 11F, and the. other edges of the frame elements may be similarly' flanged at 11E if. desired. The flanges HF at the inner andouter edges of the jambsA lll are utilized in the pres.- ent instance in supporting the frame 11 imposition inthe. forms,v and as shown in FIGURE l of the drawings, openings 19 are provided in the outer and inner flanges of thev jamb to receive fastening elements such as nails for locating and supporting the frame in the forms duringl the pouring operation.

The Wellmembers 13, asrherein shown, are made from corrugated sheet metal. so as to have an arcuate form: when. viewed in plan, andthe opposite ends of thewallf members have flat coplanar flanges 13E formed thereonl for, use in the mounting` and supporting of the. well 13 in, its position of use. i

Under thepresent invention, the supporting or mount?. ing of the well in its position` of` use is accomplished by cooperation of means that are provided respectivelyl on the outer llanges 11F of; the` jamb and on the flanges 131j ofthe wellmembers. Such mounting and securing means,Y under, thepresent. invention, areso formed and arranged that the securing or mounting'means do not in any way interfere with the mounting of the window frame in the forms, and yet such means are readily operated after the forms have been removed. to enable the well members i3 to be putin place across the outer face of the window` opening.

Thus, such cooperating'meansr as herein shown, comprise slots in oneof the members and cooperating threaded devices carried by the other member, in the specilic form shown, the means that are associated with the window frame ll are provided by a plurality of screws 20 or studs that are inserted at vertically spaced points through the outer flange HS of each jarnb and such mounting is accomplished in a way that in eect recesses the heads 20H of the screws into the outer faces of the flanges 11F so that these heads do not interfere with the mounting of the window frame 11 in the concrete forms. Thus, the flange 11F at each point where a screw 20 is to be mounted is perforated and recessed inwardly as at 20R, FIGURES 3 and 4. The screws 20 are preferably of the self-threading type usually used with sheet metal, and in the initial assembly of the frame 11, the screws are inserted into the ange 11F so that the heads 20H of the screws are located completely within the recess ZUR, as shown in FIGURE 3. With this arrangement, the ilange 11F may abut the adjacent surface of the outer form 15 as shown in FlGURE 3. If a narrow type window frame is used, the space between the frame and the inner form 14 may be lilled by the usual ller or brick. After the frame 11 has been thus mounted in the forms, the wall W is poured, and it should be noted that the screws 2) are preferably coated with a parting substance such as grease so that after the concrete has hardcned the screws 26 may be backed partially out of the concrete t a point where the heads 20H of the screws extend outwardly from the outer surface ofthe wall W.

When the forms have been removed and the screws 20 have been backed out of their openings for a short distance, the workman may readily and easily mount the well members 13 in position on `the well, and to facilitate this, the iianges 1'3F of the Well members have a plurality of vertically-spaced inverted keyhole slots 22 formed therein. It will be noted that adjacent screws 20 are equally spaced from each other and that the vertical spacing between the slots 22 is, in each instance, equal to one-half of the vertical spacing between the mounting screws 20. This provides for association of the well members 13 with the mounting screws 20 at any one of a plurality of different levels as determined by the proposed outside grade level that is to be established about the building.

When the screws 20 have been backed out, a single workman may lift the well member 13 and may engage the selected keyhole slots 22 with the screws 20, the heads 26H passing through the enlarged lower ends of the keyhole slots and when this has been done, the Well is lowered slightly so that the heads 20H are disposed opposite the narrow upper ends of the slots 22. The Workman may then tighten the screws as shown in FIG- URE 4 of the drawings so that the Well is held securely in position and tightly against the outer ange 11F of the jamb of the window frame.

From the foregoing description it will be apparent that the present invention materially simplifies and reduces the cost of installing well-type basement window assemblies, and particularly, it will be evident that the present invention so simplifies the association of the well member with the wall that the mounting operations may be performed by a single workman and this may be done quite rapidly and reasonably.

Thus while we have illustrated and described a preferred embodiment of our invention it is to be understood that changes and variations may be made by those skilled in the art without departing from the spirit and scope of the appending claims.

We claim:

1. A basement window adapted to be cast in place in a concrete Wall of a predetermined thickness and which may serve as a form for the window opening as the wall is cast, said Window comprising a sheet metal frame having a thickness from its inner side to its outer side equal to said predetermined thickness of the wall in which the frame is to be cast, said frame having a pair of suhstantially vertical ilanges extending away from each other along the outer vertical sides of the frame, said flanges each having a plurality of inward recesses with central openings therein formed in said vertical anges at vertically spaced points, locking screws threaded through said openings and having heads disposed withinthe respective recesses ush with the outer surfaces of said vertical flanges so that said flanges may receive a form in flush engagement therewith, said screws being retractable from the ilush positions thereof for use in locking a Well member to the window frame.
