per sash and a lower sash which are respectively mounted in separate grooves or equivalent in the exposed lateral faces of the window casing and equipped with sash cord and weights or equivalent pursuant to the usual practice to effect the vertical upward and downward movement of the respective-upper and lower sashes within the window casing. The upper sash carries theglass for the same in a frame identified herein as the upper glass frame, which is pivotally mounted at its opposite sides to swing about a horizontal axis. --The abutting faces of the respective upper, lower and lateral strips of the upper'glass frame and the upper sash are arranged relative to one another to attain automatic locking ofthe upper lass frame when the upper sash is in its osed glass frameof position. Similarly, the glass of the lower rash is mounted in a frame identified herein.

as the lower glass frame, which is pivotally supported in the lower sash to provide for rotative movement on a horizontal axis, and the abutting upper, lower and lateral strips of the glass frame and of the lower sash are related to one another to provide for the automatic locking of the parts when in their closed position. I

Fig. 4 is an exploded perspective view of certain detail parts of myinventio'n;

Fig. 5 is ,an exploded view in perspective, showing a manner of assembly of a glass frame in its sash and the interconnecting pivotal mounting members; and- Fig. 61s a perspective view showing the stage of final assembly of the parts illustrated in Fig. 5.

I Referring to Fig. 1, the window casing may be of the regulation or any approved form. The upper sash 11 is shown in Fig. 1 in its raised position. The lower sash 12 is shown in Fig. 1 in its lowered position and its glass frame 13 in an open position by swinging the same. The view illustrated in Fig. 1 is tha from theinterior of the building, the sill 14 representing the inside sill of the window casing 10.

The manner ofassociating the upper sash 11 and the lower sash 12 to provide for the vertical upward and downward movements of the same may be as desired; I have illustrated in the drawings the common form of such arrangement including the sash cord 15, see Fig. 2, one end 16 of which, is secured to the outer face of the right-hand side 17, see also Fig. 1., of the lower sash 12, then extends upwardly over the pulley 18, thence downwardly within the hollow inte-.

rior of the window casing 10 to be connectedto the sash weight 19. The guide strip 20 is located between the respective edges of the inner and outer faces of the outer strip 21 and inner strip 22 of the respective lateral sides of the window casing 10 to provide for the two usual grooves for guiding the uppler sash 11 and the lower sash 12 respective y. i

In Fig. 2, the upper glass frame 23 is shown in its rotated and open position. The glass of the upper frame 23 is indicated at 24 and is inserted in its frame 23 in the regulation or other approved manner. The pivotal mounting of the frame 23 in its upper sash 11 may be etfectedlin any desired man- H ner. In the forms of my invention 'illustrated in the drawings, I have employed the simplest form of such pivotal mountin comprising the pivot plate 25 provided wit the. pivot pin 26 and the com lementary socket plate 27' is provided wit a socket opening 28 for receiving the pivot ,pin 26.

- The pivot plate 25 is secured by screws 29 to the oppositely disposed lateral strips 30,

31 of, say, the glass frame 23 and the socket either the upper or the plate 27 is secured by the screws 32 to the oppositely disposed lateral strips 33, 34 of the upper window sash 11.

Such complementary pivotal mounting plates serve also as wind jambs for the extents of the lengths of such plates and coact with other parts serving as auxiliary wind jambs for the remainder of the height of the upper sash, as is set forth more fully hereinafter.

A similar arrangement of complementary pivotal mounting plates, and serving also as wind jamb parts, 1s provided for the mounting of the lower glass frame'in the lower sash, and like parts are designated by like reference numbers with the suflix a. 4

Preferably, the upper glass frame 23 is related to its sash 11 to attain automatic lQCk'. ing of the glass frame 23 upon the movement of the glass frame '23 to its closed position.

Such locking relationship is had by the provision of the offset or an ular faces between lower strips of the glass frame 23 respectively relative to the upper and lower strips of'the upper sash 11; in the most preferred form of my invention such locking relation is provided at both of the locations named. One form of such locking relation is effected by providing the extension 35 projecting upwardly of the outer ortion of the upperstrip 36 of the glass ame 23 which when the glass frame 23 is in its closed position is received'within a correspondingly cut-away recess of the upper strip 37 of the upper sash 11. Similarly, the lower strip 38 of the upper glass frame 23 is cut away as indicated at 39 to receive the upward extension 40 of the lower strip 41 o the upper sash 11- It will be observed that the oppositely disposed lateral strips 28, 29 of the upper glass frame 23 may be. of the full width of the upper and lower strips 36, 38, and in this instance the upper strip 36 is shown as the wider strip.

It will be noted in Fig. 2 that the upper sash 11 has been moved downwardly some.-

. what from its uppermostposition to clear the extension 35 of the upper stop strip 42 of the window casing 10. When it is desired to close the upper sash, the glass frame 23 is swung in the opposite direction, namely in counter-clockwise rotation, to bring the aforesaid interlocking strip parts to their mutually locking positions, whereupon the up er sash 11 is pushed upwardly, the aforesai extension 35 being received between the upper strip 37 of the up er sash 11 and the sto strip42 of the window casing 10, thus loc ing the parts of the upper sash 11 and of the upper glass frame 23 in their closed positions.

The securement of the aforesaid parts of the upper sash to the upper glass frame may be had by the regulation or other approved form of window lock such as is illustrated in.

the drawings and comprising the catch member' 43 and the pivotal cam member 44. However, in carrying out my invention, the catch member 43 is secured by screws or the like to the lower strip 40 of the upper sash 11 and the pivotal cam member 44 secured by screws or the like to the upper strip 45 of the lower sash assembly.

The lower sash and its glass frame are similarly arranged in self-looking position when the upper sash and the lower sash are in theirmutually closed and locked position. The glass of the lower sash is indicated at 46 and ismounted in a frame comprising the upper strip 45, the oppositely disposed lateral strips 47, 48 and the lower strip 49. One form of such mutually locking relation for the assembly of the lower sash parts is had by locating'the upper stri 52 of the lower sash 12 intermediate the lbwer strip 40 of the upper sash-11 and the upper strip 45 of the lower glassfra'me. In such arrangement the pivotal cam member 44 is secured to the upper strip 45 of the lower glass frame.

In the embodiment illustrated in the drawings, the lower glass frame is mounted to swing by turning the. same in clockwise direction as is indicated by the arrows 50. The pivotal mounting, as above indicated, is similar to that. illustrated in Fig. 4 relative to the pivotal mounting of the upper glass frame-23- In such arrangement, the lower strip 49 of the lower glass frame is rabbeted relative to the lower strip 51 of the lower .sash '12, the extension 49 of such rabbeted strip 49 extending on the outer face of the lower strip 51 of the lower sash 12.

The lower window sash 12 is suspended from sash cords and counter-weighted similarly to the upper window sash 11, and like 1parts are designated by'like reference numers.

, Thefunction of preventing leakage of air, rain and dust served by the complementary pivot'pin and socket plates is afforded by providing the central circular portions of each of one-half thickness and the oppositely extending arm portions of each of double thickness, the arm portions'being displaced relatively to one another to be disposed side by side and of one-half of the width of the respective lateral strips of the upper and lower glass frames, when the upper and lower glass frames are in vertical-or closed posi' .t1on.-

' The auxiliary wind jamb parts comprise the oppositely disposed jamb strips, see Fig. 5, designated '55, 56, both disposed on a lateral strip, say, the lateral strip 53 of the lower sash 12 and spaced apart to provide for the clearance required for the complementary pivot and socket members 25, 27. Similar strips 55, 56 are provided for the opposite lateral strip at of the lower sash 12, and likewise for the corresponding oppositely disposed lateral strips of the upper glass frame. i

Complementary strips are correspondingly applied to the oppositely disposed lateral strips 47, 48 of the lower glass frame and are designated 57 58. Y

Such or equivalent arrangement of complementary pivotal pin and socket members affords a simple form of assembly of each glass frame within its sash and similarly a simple form of removal ofeach glass frame from its sash. This is illustrated in the exploded view' shown in Fig. 5 and a simplified form of assembly is had by mounting the oppositely disposed pivot plates 25, 25, on the oppositely disposed lateral strips 47, 48, of the lower glass frame, then loosely placing the respective socket plates 27 with the respective pivot pins 26, 26 within the respective sockets 28*, and bodily moving the lower glass frame to position the respective sets ofpivot plates and socket plates within the spaces between the respective jamb strips '55, 56, then turna ing the lower glass frame to a horizontal pothe positionin sition as indicated in Fig. 6, thus permitting of the respective socket plates 27 to a ord access to the screw openings in the same and enable the screws 32 to be turnedby a screw driver or the like and seated in proper position, as above in dicated.

The lower sill is preferably providedwith a stop strip or equivalent for locking the frame 'ofthe lower glass 46 when the lower glass frame and the lower sash 12 are in their lowermost positions. As is illustrated in Fig. 2, such stop for the sill may be formed by cutting away a portion 61 of the upper surface of the outer sill 60 to provide a depression for receivin the lowermost- .portion 62 of the lower strip '49 ofthe lower glass-frame. Accordingly, upon closing the upper glass frame 23 and raising the upper sash 11 to its uppermost position, whereby the stop strip 42 disposed upwardly of the window casing 10 locks the upper glass frame 23 and the, upper sash '11, and the depressions6l 'ofthe sill ofthe window casing 10 locks the'lower glass frame and the lower sash 12, the closing of the lock 43, 44 locks all the parts of the uppersash, its upper glass frame, the lower sash and the lower glass frame in common in their respective closed positions.

' Such locking relation of the lower glass frame and the lower sash also precludes the jimmying of the lower sash or the lower glass frame when the parts of my improved window are in their respective locked positions.

My invention affords many advantages in its use for ventilating to varied positions of the respective up er and lower glass frames,

upper sash 11 is slightly lowered, whereupon the upper glass frame23 may be turned to any desired set position. Such ventilation is 'efi'ected without movement of the lower sash and effects such ventilation from the top of the window, as is most desirable in certain circumstances. 'When it isdesired to ventilate through the lower sash, the lower sash is slightly raised to clear the extension of the faces of the depression 61, thus permitting the lower glass frame to be turned as desired. Such ventilation through the lower glass may be had independently of the ven tilation through the upper glass, or the ventilation may be had by tilting both the upper glass frame and the lower glass frame and each to independent extents.

The cleaning of the glass of the upper sash and the glass of the lower sash is attained wholly from the interior of the window casing, thus obviating the dangersto life and limbof present day window cleaners and eliminating the liabilities entailed in present day window cleaning methods.

When it is desired to replace a broken glass, the operation of replacement is attained without removal of the glass frame, if desired, and wholly from the interior of the window casing. It will also be apparent that either glass frame may be removed from its sash, if preferred, for the purpose of replacing a broken glass, or for other purposes.

The construction of my improved window parts made of wood or like material, but it will be observed that the parts of the upper sash, its glass frame, the lower sash and its glass frame may be of steel or other suitable material and of appropriate thicknesses, somewhatreduced as compared with the dimensions indicated in the drawings, but of the same relation and arrangement and .mutually co-acting parts as hereinabove de scribed.
