As shown in Figs. 11, iirliy, and wa I frame 1 is entirelyformed of bars of wrought I metal rolled toa substantially L shaped .eross section; such bars beingmitered and joined at the corners of the frame 1 byiwelding-the' ends thereof together on the linesl'? Theihinged sash frame 14 is similarly,

formed of wrought metal bars of substantial 1y L-shaped cross section, as indicated in W FigsILIII, IV, and Vi shownFigs. 'II, III, and V; when the'sash frame ll is in closed position with respect to therwinin overlapped weathering relation inclosing a tubular recess 18 between them, which resaid-hinged sash '14: more or'less with respect to the stationary frame -1 andhold it'in ad-- justed position by-rne'ans' of "the lever-'20:-

Sa'id leveris fulerurned "on the pivot 'pin 21 in the bearingi22 Which-isrigid'ly'heldi screws 23. Said lever- 20 is' pivotally "con nected at its opposite end upon the rivet 25, carried by the slide block 26. Said slide block is mounted to reciprocate in the underout channel formed by the guide plate 27 which is rigidly connected with the lower rail 13 of the sash 14L, conveniently by the screws 28 indicated in Fig. II.

Said lever 20 has, rigidly connected therewith, conveniently by welding, in concentric relation with its fulcrum pin 21, the worm gear 30 engaging the worm 31. Said worm 31 has the squared end 32 set in a square socket in the hub 34:Of the crank handle 35, in which it is held by the screw 36 extending through the washer 37.

In the form shown, the threads on the worm 31 are of such rapid pitch that it is necessary to make but one-half revolution of said handle 35 to turn the worm gear 30 with its lever 20 through an arc of ninety degrees from closed to open position of said sash frame 14, and the inclination of the threads on the worm is such that the worm may be turned by movement of the sash. Therefore, some other'me'ans are necessary to hold the sash in adjusted position when such a rapid pitch worm is employed, and I provide said handle 35 with the axially adjustable set screw 39 which bears against the brake shoe 40 at its inner end so as to press said shoe against the arcuate flange 41 on the stationary bearing 42 which is rigidly connected with said frame 1, conveniently by the two diametrically opposite screws 43, one of which is shown in Fig. I.

nected therewith may be held in any desired position of adjustment, by clampin said brake shoe 40 against said arcuate flange ll, by turning said screw 39.

However, if the threads on the worm be made of a sufiiciently slow pitch that the worm cannot be turned by movement of the sash, it is unnecessary to provide any other means to hold the sash or its operating handle in adjusted position.

Therefore, I do not desire to limit myself to the precise details of construction and ar- .rangement. 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.

I claim:

1. In a metallic window structure, the combination with a stationary window frame; of a sash frame hinged to said window frame; the bars of said frames being channels and so disposed in opposite rela tion that when the sash is closed in the window frame there is a tubular recess between said frames extending entirely around the sash frame and closed by the flanges on the channels when overlapped in weathering relation; a lever fulcrumed at one end in the recess of said stationary window frame and having its opposite end operatively connected with said sash frame; a worm gear rigidly connected with said lever, in concentric relation with its fulcrum, in said recess; a worm mounted to rotate in said recess, between said frames, and in mesh with said worm gear; and a crank handle on said worm projecting from said recess into thebuilding, from the inner face of said window frame; whereby said sash may be openendand shut by turning said handle.

2. A structure as in claim 1; including means, adjustable independently of said worm, adapted to hold said sash in any po sition of adjustment.

3. In a metallic window structure, the combination with a stationary window frame; of a sash frame hinged to said window frame; the bars of said frames being channels, each of substantially L-shaped cross section, so disposed in opposite relation that when the sash is closed in the window frame there is a tubular recess between said frames extending entirely around the sash frame and closed by the flanges on the channels then overlapped in weathering relation; a slide block; a lever fulcrumed at one end inthe recess of said stationary window frame and having its opposite end pivotally connected with said slide block mounted to reciprocate in said recess in said sash frame; a worm gear rigidly connected with said lever, in

I concentric relation with its fulcrum, in said i That construction and arrangement are such that said handle 35 and the parts conrecess; a worm mounted to rotate in'said recess between said frames and in mesh with said worm gear; a crank handle on said worm projecting into the building from the inner face of said window frame; and means adjustable to hold said handle in any pos-i- 7 tion of adjustment of said sash, including a set screw carried by said handle.

l. A structure as in claim 3; including a brake shoe adapted to be operated by said set screw.

5. A window structure as in claim 1, wherein the worm and handle axis is transverse to the plane of the window frame, and thegearing connecting the crank handle with the sash is adapted to efiect full opening of the sash with less than a complete revolution of said handle; whereby said handle may be located close to the sill or stool at the bottom of the window sash and within the extent of the sill.

6. The combination with a window strucfull opening of said sash by approximately one-half revolution of said handle above said sill; thus avoiding projection of the sash operating mechanism beyond the sill into the building. 7 I

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsyl- Vania, this 30th day of December, 1930.
