20 Claims.

My invention relates to casement windows provided with continuous Weatherstripping and in-,

sect screens at the inner side thereof. As ordinarily constructed, casement window sashes are provided with means to open, close, and fasten them in adjusted position which require some' portion of the building, such as a sill, stool, or sidewall or jamb of the window opening, to support them. Ordinarily, the screens for suchvwindows are of two types, either inwardly arched over the means for swinging the'sash or having an opening through the screen for such sash operating means. Such ordinary structures are objectionable, first, because it is impossible to assemble them completely at the factory and necessary to employ skilled labor 'to fit them and attach the parts aforesaid thereof to the building sills or walls. Second, the cost of construction of screens which are arched or providedwith openings through them for manipulation of the sash operating means is far in excess of ordinary plane screens, such as may be utilized with sliding sash windows. Third, if the sash operating means is within the sight of the window frame, (and in some ordinary structures such means are mounted inthe middle of such window space and require a frame bar to support them); the view I and ventilation through the window space are obstructed.

Therefore, objects and effects of my invention are to provide a casement window structure including an insect screen, of either flat or roll type, which is imperforate except for the reticulations thereof, and detachably mounted upon the inner face of said structure; wherein the sash operating and locking means are outside of the perimeter of the screen, the casement sash is completely operable by rotation of a single handle, which does not project into the room, and is permanently connected with the window structure so that it cannot be lost or mislaid, and the sash locking means isoperated to lock the sash as a consequence of rotation of said handle, which moves a locking cam. Such a window structure may be completely assembled at the factory, in instant readiness to be inserted in a window opening in a building; all parts of such structure being supported by the outer frame thereof, independently of any portion of the building.-

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

In said drawings; Fig. I is an inner face view of a complete window structure embodying my invention. Fig. II is a plan sectional view of said structure, taken on the line II, II in Fig. I, but on a larger scale. Fig. III is a fragmentary sectional view, taken on the line III in Fig. I, showing the sash operating means in elevation. Fig. 30 IV is a fragmentary plan view of the essential elements of the sash operating means indicated in Fig. II, but on a larger scale, being full size.

Fig. V is a fragmentary vertical sectional view of a modified form of my invention including weathering means extending entirely around the casement sash and a molding seat for a removable plane screen, extending across the bottom and up both sides of the screen. Fig. VI is a fragmentary vertical sectional view, similar to Fig. V, but showing a modified form of my invention adapted for cooperation with a screen mounted upon a roller at the top thereof. Fig. VII is a fragmentary plan sectional view, taken on the line VII, VII in Fig. VI. Fig. VIII is afragmentary plan'sectional view, taken on the line VIII, VIII inFig. I, but on a larger scale, and showing the automatic locking mechanism. Fig. IX is an elevation of the locking structure shown in Fig. VIII, as seen from the 30 lower side of the latter. Fig. X is a fragmentary plan sectional view of the locking lever, taken on the line X, X in Fig. IX. Fig. XI is a front elevation of the locking lever housing shown in Fig. IX. Fig. XII is a plan view of the locking cam 5 shown in Fig. IX. Fig. XIII is an elevation of said locking cam as seen from the lower side of Fig. XII. I

In said figures; the stationary window frame 1 has oppositely counterpart hinge brackets 2 and 3 respectively rigidly connected with the top -rail 4 and bottom rail 5 of said frame 1 and projecting outwardly from the latter, as shown in Fig. 11. Said stationary hinge brackets 2 and 3 are connected by pintles 7 and 8 with respective hinge brackets 9 and 10 which are respectively rigidly connected with the top and bottom rails 12 and 13 of the sash 14 and project outwardly therefrom, as shown in Fig. II. Said sash 14 is thus hingedly supported by the frame 1 so that when in the open position shown in dotted lines in Fig. II the plane of the sash is offset toward the middle of the frame far enough to afford access from the interior of the building to clean the outer surface of the glass 15 in said sash.

Said frame 1 is entirely formed of bars of wrought metal rolled to the substantially L- shaped cross section shown in Figs. 11 and V, such bars being mitered and joined at the comers of the frame 1 by welding the ends thereof together on the line 17 in Fig. I.

The hinged sash frame 14 is similarly formed of wrought metal bars of L-shaped cross section, as indicated in Figs. II and V. As shown in Figs. II and V, when the sash frame 14 is in closed position with respect to the window frame 1, the flanges of both frames are in overlapped weathering contact relation at two lines extending entirely around said sash frame, and with the tubular recess 18 thus sealed between them, and containing the sash operating gearing.

Said hinged sash 14 may be opened more or less with respect to the stationary frame 1 and held in adjusted position by meansof the lever 20 which is indicated in Fig. 11 in both extreme positions of its range of movement, respectively with the sash 14 shown in full lines tightly shut in the frame 1 and with the sash shown in dotted lines extending in a plane at right angles to the frame 1.

Said lever is fulcrumed on the pivot pin 21 in the bearing 22 which latter is rigidly held on said frame 1, conveniently by the three screws 23.

Said lever 20 is pivotally connected at its opposite end upon the rivet 25 carried by the slide block 26 which is mounted to reciprocate in the undercut channel formed by the guide plate 27 which is rigidly connected with the lower rail 13 of said sash 14, 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, as shown in Fig. IV, and within said recess 18.

Said worm 31 is conveniently journaled at its inner end 32 in a socket 33 in said bearing 22' and journaled at its outer end in the bushing 35, which is conveniently a plug screwed into said bearing 22 and abutting against the shoulder 36 on said worm. Said worm is conveniently squared at its outer end 38, as shown in Fig. IV, and fitted in a similarly shaped socket in the hub 39 of the crank 40 which is provided with the rotary handle 41. Said crank 40 is normally rigidly connected with said worm 31 by the screw 42 which extends through said hub 39 in threaded engagement with the socket 43 in the squared portion 38 of said worm.

The axis of said worm 31, which is indicated by dash lines 45 in Figs. III and IV, is inclined upwardly and outwardly from the lower right hand corner of said frame 1, obliquely both with respect to the vertical plane of the window and the horizontal plane of the stool or sill 46. The purpose of such double inclination of the axis 45 of said worm, is to permit rotation of said crank 40 within the opening in the building wall in which said frame 1 is set and above said horizontal plane 46.

Such construction and arrangement permits the window structure above described to be completely assembled at the factory, ready to be set in the window opening in the building without any connection of any part of the sash actuating mechanism with the wall, sill, or stool.

As shown in Figs. I, II, and III, the foraminous insect screen 48 is stretched in plane position in the rigid rectangular frame 49, the lower rail 50 of which fits in the seat 51 in said bearing 22 which is rigidly connected with the frame 1, as above described.

As shown in Fig. I; said screen frame 49 extends within the angle bracket 53 which is rigidly connected with said frame 1, conveniently by the screws 54, and the right hand edge of said frame 49 fits against the angle bracket 55 which is also rigidly connected with said frame 1, conveniently by the screws 56. The spring clip 58 which overhangs and holds the upper edge of said screen frame 49 is likewise rigidly connected with said frame 1 by the screws 59 so that said screen 48 is rigidly held in close relation with the inner face of said frame 1 but may be readily detached therefrom by merely upwardly bending said clip 58 to release the top edge of said screen frame 49 so that the latter may be tilted slightly forward at the top and lifted from its normal engagement with said seat 51 and brackets 53 and 55.

As indicated in Fig. III, the rails of said frame 49 are conveniently formed of thin sheet metal folded to form a recess 60 which is rectangular in cross section and adapted to receive the rectangular bars of the screen retaining frame 61 by which the foraminous screen fabric 48 is stretched and held in said screen frame 49. However, it is to be understood that said screen frame may be otherwise constructed and arranged.

For instance, in Fig. V, I provide the stationary window frame 1 with the molding 63, which is U-shaped, extending across the bottom rail '5 of the frame 1 and upwardly at the opposite sides of said frame to form a seat 64 for the screen frame 49. Said molding is conveniently formed of three similar strips of sheet metal, folded as indicated in the lower portion of Fig. V, and mitered at the opposite ends of the lower strip to the upright strips 65 like the frame 1. Said upright strips 65 are conveniently welded at their upper ends to the top molding 66 to form a rectangular frame. Said molding 66 is shaped differently from said molding 63, as shown in the upper portion of Fig. V. Said molding 63 is conveniently rigidly connected with the frame 1 by screws 68 which extend through said frame 1 in engagement with the flange 69 on said molding 63. Said molding 66 is similarly rigidly connected with said frame 1 by screws 70 engaging the flange 71 on said molding 66, and said flanges 69 and 71 serve to hold in proper operative relation the weathering strips 72 which extend all the way around the sight opening in said frame 1 and are conveniently formed of thin spring metal, preferably bronze, so as to contact with the inner flange 73 on the hinged sash 14, to make a weatherproof joint with the latter when said sash is shut to the position shown in Fig. V; it being understood that when said sash is open, said weathering strips 72 project further to the left than they are shown in Fig; V.

Said screen frame 49, shown in Fig. V; is resiliently engaged at its upper edge by the spring clip 75 which is like said spring clip 58 but rigidly connected with said molding 66 by the screws 76. It may be observed that in the form of the invention shown in Fig. V, the foraminous screen web 48 is continually stretched in plane position by the retainingframe 77 which differs from the retaining frame 61, shown in Fig. III, in that it is of U-shaped cross section and. therefore less costly to manufacture.

However, as shown in Figs. VI and VII, a window structure such as above described and provided with moldings 63, 65, and 66, as in Fig. V, may be utilized to support in cooperative relation therewith, an insect screen of the roller type. The foraminous screen fabric 79 which may be raised and lowered, is fastened at its upper end to and carried by the roller 80 upon whichv it may be rolled like a window shade. However, it may be withdrawn to plane position, as indicated in Fig. VI, by means of the angle bar 81 secured at the lower edge of the forammous fabric 79 and having opposite end flanges 82, one of which is shown in Fig. VII, adapted to slide between said molding member and guide bars 83, as indicated in Fig. VII. Said guide bars 83 are conveniently formed of thin resilient sheet metal, such as bronze, folded to the configuration shown in Fig. VII, and sprung over tho molding 65. As shown in Fig. VII, said angle bar 81 may have at its opposite ends plates of resilient sheet metal 84 for sliding contact with said guide bars 83.

Although said swinging sash 14 may be held shut by the operating mechanism above described, the latter is so close to the hinge that the sash may be used as a lever in a felonious attempt to open it. Therefore, it is desirable to provide it with locking means at its left hand edge, shown in Fig. I remote from said operating mechanism, to hold it shut independently of the latter. However, ordinary locking means for such sash must be manually set in locked position and, consequently, the question of whether the sash is locked or not when closed is dependent upon the attention of the operator. Therefore, I prefer to provide sash locking means which are automatically operative as a consequence of the rotation of said crank 40 so that whenever the sash 14 is shut, it is certainly locked thereby, without the attention of the operator. Such preferred locking mechanism is shown in detail in Figs. VIII to XIII inclusive and includes the oscillatory la ch lever 86 which is fulcrumed on the stud 87 in the housing 88. Said housing is rigidly connected with said stationary frame 1, conveniently by the four screws 89 shown in Fig. IX. Said latch lever has the slot 90 for engagement with the stop stud 91 which limits its oscillatory movement. Said lever has, in unitary relation therewith, the crank arm 93 provided with the cylindrical crank projection 94 which, when the sash is locked, engages the cam ledge 95 in the cam recess 98 in the cam lock, keeper, plate 97, as shown in Fig. IX. Said cam plate 97 is rigidly connected with the .left hand edge of said swinging sash 14, con veniently by the two screws 98, as shown in Figs. VIII and IX. As shown in Fig. XIII; said cam plate 9'7 has the cam projection 99 which extends above the level at which said crank projection 94 is normally presented by gravitation of said lever 86 and serves to tilt said lever and guide said projection 94 into said recess 96 when said sash 14 is swung shut by rotation of said crank 40. Consequently, the effect of such rotation is to automatically engage said cam plate with said crank projection 94 in the locked position shown in Fig. IX, without any manipulation of said lever 86 and merely as a consequence of closing the sash 14.

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.
