The "latter =device :however serves -to effect such movement andis preferably fcOnneCtd-ti) the: lowenportion of thewsashnand rframeso that titzwilhbe easilyzaccessible; especially :i'sozwhen=applied to windows.

.sMecha'nism-i l consists of aplate 22 that is slid-s ably mounted orr-b1ock;24,= the :block'being provid- -'.-ed'.with lateral flanges 25 :(see-.Fig.13) :-that engage recesses 26 formed in guide members 23 secured to the plate. Plate 22 is preferably of square shape and is provided with a flange 22a which serves to enclose the above parts. Pivotally mounted on a stud 2'7 projecting from plate 22 is a lever 28, which serves to shift plate 22 on the block 24. Secured to lever 28 is a pin 29 that projects into a slot or recess 30 formedin block 24, there being an arcuate slot 31 formed in plate 22 to accommodate movement of said pin. Block 24 is secured by screws or the like 32 to one flange of an angle bracket 34, the other flange 35 of which is adaptedto be rigidly secured to the inner face of the side rails of frame 10. Hing 'edly connected to plate 22 as indicated at 36 is a leaf 37, which is adapted to be secured to the outer side bars 18a of the sashes, said leaf being bent as indicatedat 38 to facilitate such connec-- tion.

' Mechanism 20 consists of a plate 40 that is hingedly connected as indicated at 41 to a leaf 42 which is adapted to be secured to the side bar 18a of the sash. v

' then assumed by pins 29 and blocks 24', the

any distortion of the sash or frame which may 7 occur after installation, i. e. so that the plate will slide freely on the block. It will be apparent that due to blocks 24 and 44 being disposed at an angle when in assembled re lation in the frame as shown,.the window sasheswill travel in a diagonal pathupon 'operation'of mechanisms 21'to lock or disengage the-same.v

When the sashes are in closed or locked position thetongues and grooves18b interlock, the lower bars 180 rest on'the sill, the side bars 18a extend into the grooves 15, and the flanges 18d formed on the upper cross members overlap the ledges 14 formed in the'upper rail of the frame as shown in Figs-1,2 and 4. Hence itwill be apparent that a substantially leak-proof seal is then formed, also thatthe sashes cannot be opened from the outside. I

It will be noted'that sufficient clearance is allowed between top and side edges of the sash and grooves formed in the frame (when in closed position) to permit upward and lateral movement of the sashes. v 1

When it is desired to open one of the sashes the lever 28 of mechanism 21 is given one-half turn in the direction indicated by the arrow A, the action of which through contact of pin 29 with the lower edge of the slot 30 in block 24 '(which is held againstmovement) disengages one sash from the other as shown in Fig. '3. During such movement plate 34 of mechanism 21 will have'been moved upwardly and outwardly on block 24 while plate 40 of device 20 will in like manner move on block 41, as shown in Figs. 10 and 11.

It will be noted that due to relative positions sashes will be retained or held in disengaged position. In other words, they cannot return to locked position by gravity until'the lever is turned in the opposite direction.

When thus disengaged, the lower end faces .21'in the manner above described, either or both of the sashes may be opened in the usual manner, as indicated by dotted lines in Fig. 7.

By turning lever 28 upwardly after opening the sash the same may be locked in partially open-position as shown in Fig. '7.

From the foregoing it will be seen that the improved casement window construction may be quickly installed and very efficiently serves its intended purpose.

. I claim:

1. A sash operating mechanism comprising a bracket, a block having a slot formed therein secured to said'bracket, a. plate slidably mounted on said block, a leaf hingedly eonnectedto said plate, and a lever provided with a pin ,pivotally mounted on said plate with the pin thereon ex tending into the slot in said block, whereby on turning of-'the lever said plate may be simulta- 'neously' shifted vertically and laterally on said bracket. y

2. A sash operating mechanism comprising 93 1 05 bracket, a block having a. slot formed therein secured to said bracket, 9. plate slidably mounted on said block, a leaf hingedly connected to said plate, diagonally disposed guide means secured to said plate and engaging said block, and-" a lever provided with a pin pivotally mounted on said plate with the pin thereon extending into the slot in said block, whereby on turning of the lever said plate may be simultaneously shifted vertically and laterally on said bracket.

8. A sash operating mechanism comprising a bracket, 2. block having a slot formed therein secured to said bracket, a plate having an armate slot formed therein slidably mounted on said block, a leaf hingedly connected to said plate,andia lever pivotally mounted on said plate and having a pin thereon extending through the slot therein into the slot in the block on said bracket, whereby on turning of the lever said plate may be simultaneously shiftedvertically and laterally: on said bracket.
