18 to cont-act with the lower surface of the sill to prevent the elements from passing between the sills, and a similar weather strip is secured to the lower surface of the lintel 19 to bear on the lintal 16 to prevent the elements from passing between the lintels. As seen in Fig. 1, the upper surfaces of the sills 15 and 13 slope outwardly, with the outer edge portion of the sill 15 overhanging the sill 13 beyond the weather strip 34;, so that the sills will effectively shed rain and moisture therefrom.

A stop bar 36 is hingedly mounted, as at 3T, at the inner edge of the sill 13 to swing upwardly and outwardly to a position along the lower end of the frame 13, in order to prevent the f ame 13 from turning', and to also provide a neatl finish between the sills of the frames at the inner side of the window.

For convenience in swinging the bar 3G upwardly, when it is desired to turn the frame 13, a lifter 3S is. slidable verticallj1 in a guide 39 carried by the sill 15 of the frame 13,` and has a finger 410 at its lower end disposed under the bar 3G, as seen in Fig. f1, and said lifter has a linger piece or hook 41 at its upper end, whereby the lifter may be conveniently raised so that the linger a() thereof swings the bar 36 upwardly and inwardly. The bar 36 may then be swung downwardly out of the path of the sill 15 when the frame 13 is turned.

Outer and inner stop 'bars 4t2 are hingedly connected, as at 43, with the lintel 19 of the frame 13 and are adapted to swing upwardly into rabbets 111 in the lintel 19 of the frame 12 to provide a snug and neat joint between the two frames. The bars a2 are swungr upwardly yieldingly by means of coiled springs connecting said bars and extending across the lintel 16 within grooves or channels 16 formed in said lintel, or the lintel may have bores or openings extending therethrough to accommodate said springs. i `In order that thebars 42 will bewung downwardly smoothly when the frame 13 is turned from normal position and will swing upwardly snugly into engagement with the frame 12 when the frame 13 is returned to normal position, the bars 42 are formed with rahbets 11T extending from those ends thereof which move under the lintel 19 when Athe frame 13 is swung from normal position.

13 will cause the bars l2 to be swung down- `wardly so as to pass under the lintel 19.

rlhe ends of the bars -12 opposite to the rabbets 47 are adapted to abut the upper end portions of the stops 33 when the frame 13 is in any position, and the ends 50 of the bars l2 frein which the rabbets -17 extend are cut obliquely so as to more into wedging engagement with the upper end portions of the stop bars 31 that are eut away and bevelled, as at 19, as seen in Fig. 6, for the engagement; of the bevelled ends 50 of said bars 12. The clearance between the walls 43 of the rabbets Il? and edges of the lintel 19 are sullicient to permit the bars L1-2 to swing upwardly into place in overlapping relation with the lintel 19, or within the Iabbets L11 thereof, and as the bars 12 swing upwardly into place the ends 50 thereof come into tight contact with the bevelled portionsl 49 of the stop bars 31. "lhus, as seen in Fig. 1, the joint between the bars 31 and 42 is neat and plain. In fac-t, both the inner and outer sides of the window are plain and neat, without any objectionable protuberances or recesses such as would mar the appearance of the window or would otherwise be objectionable.

lilith the present eonstructioinit is only necessary to swing the bar 36 inwardly and downwardly, to permit theframe 13 to be turned, so that the outer side of the sash panels may be cleaned, or the window screen applied to or removed from the outer side of the frame 13. The bars l2 are automatially swung when the frame 13 is turned from and returned to normal position, and the stop bars 31 and 33 are fixed to the respective frames.

The improvements may be embodied in a window construction made of metal as well as a construction composed `of wood, as shown. j

Having thus described the invention, what is claimed as new is:-

1. A `window comprising a 4main frame, a supplementary fra-me mounted for turning movement therein about a vertical axis, and a spring influenced bar hinged to the lintel of the supplementary frame to swing upwardly and overlap the lintel of the main frame, said bar having a rabbet extending from one end to provide a clearance between the bar and the lintel of the main frame.

2. A window comprising a main frame, a supplementary frame mounted for turning movement therein about a vertical axis, and a spring` influenced bar hinged to the lintel of the supplementary frame to swing `upwardlyv and overlap the lintel of the main frame, said bar having arabbet extending from one end to provide a clearance between the bar and the lintel of the main frame, said end of the bar being bevelled, and the main frame having a .stop bar for the contact of the Supplementary frame and proyvided with a bevelled portion for the conand adapted to swing upwardly into overlapping relation with the lintel of the main frame, and springs connecting said bars for swinging them upwardly.

5. A Window comprising a'main frame, a`

tary frame atrthe opposite edges thereof and" adapted to swing'upwardly into overlapping relation with the lintel of the main frame,

and springs connecting saidfbars for swinging them upwardly, each ofsaid bars having a rabbet extending from one end to provide a clearance between said bar and the lintel of the main frame.

G. A window comprising a main frame, a supplementary frame mounted for turning movement therein about alvertioal axis, stop bars hinged to the lintel of the supplementary frame at the opposite edges thereof and adapted to swing upwardly into overlapping relation with the lintel of themain frame, and springs connecting said bars for swinging them upwardly, eaoh of said bars having a rabbet extending from one end to provide a Clearance between said bar and the lintel of the main frame, said ends of the bars being bevelled, and the main frame having stop bars for the Contact of the supplementary frame` and formed with bevelled porti-ons against which said ends of the rstnamed vbars are seatable when said first-V named bars-move into overlapping relation with the lintel of the main frame. Y

7. A window comprising a main frame, a supplementary frame therein,`pivot means between the sills of said frames, and a pivot trunnion inserted upwardly through theVL lintel of the supplementary frame and en# gaging the lintel of the main frame.

8. A window comprising a main frame, a supplementary frame l'therein having a lintel with a lower parting ,strip groove, pivot means between the sills of said frames, and a plate seated upwardly in said groove and having an upstanding trunnion extending through the lintel of the supplementary frame and engaging the lintel of the main frame. p

9. A window comprising a main frame, a

Ysupplementary vframe mounted for turning i movement therein vabout a vertical axis, a stop'bar hingedly connected with the sill of themain frame to swing to a position adja- 1 cent to thesill of the supplementary frame to maintain the supplementary frame in normal position, and means movably carried by the supplementary frame and having a portion to engage under said bar for swinging said bar upwardly from said position. Y

l0. A window comprising a main frame, a supplementary frame mounted for turning movement therein about a vertical axis, a

Astop bar hingedly connected with the sill of the main frame to swing to a position adjacent to the sill of the supplementary frame to maintain the supplementary frame in normal position, and a lifter carried by said supplementary frame and having a finger to be disposed bel-ow said bar for swinging said bar upwardly and away from the supple-l mentary frame when said lifter is raised.

n testimony whereof I hereunto atx my signature.
