Briefly described, my invention, as'sh'own.

in the (Irawiiigs;: cam uses hollow members of sheet metal, preferably, though not necessarily, copper, that, respectively engage the glass on the outer side, and the inner side, the outer member for convenience being hereinafter termed the sash, and the inner member being termed the gutter,

and which members are of identical con struction on all four sides of the glass, namely sill, side j'ambs and head amb.

Referring now in detail to what appears in Figs. 1 and 2, the sill 10, is, as is common,

of wood, and upon its top set back from the front is a stop 11 of wood, and the side and head jambs have corresponding construction. The sill has its outer face and top covered with a copper covering 12, which at the rear has a vertical flange that covers the face'of the stop 11, so that all thereby protected.

The sash comprises a base 13 with vertical flanges l4spaced a substantial distance one in advance of the other, whose edges engage the sill or jamb and an inwardly extending inclined or oblique member 15,

wood surfaces that require protection are that reaches from the outer flange 14, to the glass 16 which it engages by a lip 17, and

by. or is inelud'edf within the terms by an inwardly inclined woocl sorew 1'8, t-he; sash, by indirect pressure broughtto'bear upon the oblique niemberj l 5, is 'madef to exert- 15 ositive: yet resilient pressure" against the outer-sideof the glass toclamp it against the gutter on the inside: The oblique meniber '1-5'isgiven' the contour o'f a' niol'ding t'o enhance its appearance and to ender-n: elastic between its} front; flange 14 and 1 its glassaengaging lip;

Holes 19 are provided at intervalsthrough each flange 14, for ventilation, and in the case of the sill, for drainage, and these holes are-staggered so-that no dust canpass directly through the holes in both flanges, but it is trapped between them, for there can be no direct currents of air through the base, which, with the diminution of the force of the flowing air, by reason" of its'circuitous course, hinders the passage of dust.

The arched form of the base enables the 1' of, and there has aflange 22 at right angles 7 that lies parallel with the top portion 21 and reaches to the face of the stop, or the copper cover thereof, so that, as the gutter is secured by screws 23 to the stop, there are two parallel spaced portions at right angles to the glass that resist the inward pressure dust are diminished and changed.

these twoparallel portions are holes 24 at intervals for ventilation and drainage (in the case of the still), and as there are these two portions the holes are staggered, as "in the case of the sash base, and thus the force and direction of air currents, that would carry The gutter has at its rear edge a hollow bead 25 that forms a barrier to water tending to pass'to the top of the stop that has no protecting covering.

The holes in the top or outer member 21 have an inturned flange 26, that so directs water from the gutter that it is kept from flowing along the underside of the portion 21 to the 'joint at the top of the stop.

In;the form of my invention shownin Fig. 3, the sash 27 is the sameasin Figs. 1 and 2, but the gutter and sill cover are different, the sill cover 28 not reaching to the front of the stop 29, but the latter is covered by a flangeBO from the gutter 31, and the latter has a sub-gutter 32, formed by vertical flanges and a base. I

I claim:

1. lVindow construction having, a glassengaging hollow sash of sheet metal provided with a base extended a substantial distance in the direction towards the glass, and having an obliquely extending portion reaching from the outer side of the base towards the glass, said obliquely extending portion and said base being joined and the base being plane and having at its outer and inner edgesvertical flanges,.and downwardly and inwardly extending screws passi'ngthrough alining holes in said obliquely extending portion and saidbase, the screws having heads to engage and exert clamping pressure against sald obllquely extending portion, the holes in the base being situated and an opposing member ofsheet metal that has a portion extending horizontally inward from the glass, a supporting surface over which such portion extends and upon which it bears, said horizontally extending portion terminating in a hollow bead that extends transversely of the window, and said sheet metal member having next the glass a vertical glass engaging portion that extends downwardly from said horizontally extending portion, the latterIb-etween said bead and said vertically extending portion being plane, and said sheet metal memberhaving ahorizontally extending portion that terminates in a free edge and a vertical surface against which such free edge bears, whereby inward pressure on the glass is transmitted through said last named horizontally extending portion to the vertical surface with which its free edge contacts.

In testimony whereof I hereunto aflix signature.
