CASEMENT WINDOW OPERATOR AND LOCK Filed Sept. 30. 1929 2 Sheets-Sheet 2 Patented July 4, 1933 UNITED STATES WILLIAM E. DRUMMOND, or RIVER FOR-EST, "rumors oAsEMEN'r WINDOW orsaa'ron AND LooK The present invention relates to casement windows of the type having one or more swinging leaves or sashes, and more specifically to an improved construction of locking means to hold the sash in closed position and an improved construction of mounting the sash on the frame of the window.
One of the principal objects of my invention is to provide an improved latching means controlled by the casement stay and which secures the sash firmly at both the top and the bottom.'
Another object is to provide an improved stay means for holding the swing leaf or sash securely in either closed or adjusted open position and without likelihood of rattling or becoming unlocked.
These and other objects, that will be apparent through the further description of the invention, are attained in the "apparatus hereinafter described and. illustrated in the accompanying drawings, wherein:

,line88 in Fig. 4: and showing the latch means for retaining the swing leaf in thesubframe; and
Fig. 9 is afragmentary view showing the casement stays in latched position as they would appear from the inside of the building. g j o Referring first'to Fig. 1,.it-will be-seen that the swing leaf or sash 1 is mounted upon a casement frame 2 which is adapted to be placed in the wall 8 of a building. The sash ,1 is hing'edly mounted upon the frame 2 by means of sub-frame 5, having top and bottom arms 7 and 8 extending along the top and bottom, respectively, of the sash 1, as shown in Fig. 1. The sub-frame 5 is provided with a pair of studs 9 and 10 upon which the sash 1 is pivotally carried, the sash 1 being provided with corresponding bearing brackets '11 and 12, secured the reto in any manner, as by rivet- 7 ing, welding, or thelike, and which are received upon'the studs 9 and 10. The subframe 5 is also provided with another pair of studs 18 and'1 l which are received in brackets 15 and 16 carried by the frame 2. The sash 1 is retained in position between the arms 7 and 8 by means of manually operated catch 17, see F ig. 5, :otatably secured to the snbframe 5 and adapt-ed, when rotated to an upper position,-to pass throughaslot 18 in the sash 1, and when rotated to a lower position to secure the sash 1 within theframe 5 The casement operator is seen to consist of v a member 19, hereinafter referred to as a stay or operator because of its function of moving and holding thesash in adjusted position, having a'handleQO and notches. 21. "The stay 19 operatesthrough a slot 22 in the bottom rail of the frame 2*and as shown best in Fig. 6 is pivoted to the swing sash .1 at 23. Adjacent to the slot 22 (see Figure 6) and mounted on the front of the frame 2 is a casing 24 containing 'a' spring pressed plunger 25 acting to automatically causethe notch-es 21 to engage a tongue 40 in one side of the slot 22, thus securely holding the sash 1 in open adjusted, position. As best seen in Figure 9 the plunger 25 overlies the slot 22 and, in urging the casement stay into engagement with the tongue 10, practically closes the slot 22 soas to effectively prevent the entrance of flies, mosquitoes and other insects,
()ne of the principal features of my invention lies in the means for locking the sash in closed position which is automatically controlled by the easement operator or stay 19 and which I will now describe. The pivoted end of the stay 19 is curved and is extended to form a sort of bell crank'lever 26 which carries a rod 27 extending along the bottom of the swing sash 1 and is operatively connected to a lower locking pawl 28 which is pivoted to the sash 1 An upright rod 29 is also connected to the pawl 28 and forms the means for transmitting the movement of the lower pawl 28 to an upper locking pawl 30, also pivoted to the sash 1.
Thus it is seen that by moving the easement operator 19 against the action of the spring pressed plunger the operator is released from its notched engagement with the frame 2 and can be moved to open or close the sash 1. The operator or stay 19 is pulled through the slot 22 to close the sash and, by virtue of the offset or curved pivoted end at 23 of the stay 19, the latches or pawls 28 and 30 are held in retracted position until the sash is tightly closed. Thereafter, the stay or casementoperator 19 can be turned in a counterclockwise direction relative to its pivoted mounting upon the sash 1 as shown in Fig. 6, thus moving the rod 27 to the left and causing the pawl 28 to be drawn down behind the flange 81 of the bottom rail of the frame 2. At the same time, the rod 29 causes the pawl 30 to be moved up behind the flange 32 of the top rail of the frame, thus securely locking the sash. When the sash 1 is closed and the operator 19 is in the position, shown in full lines in Fig. 5 the latter is dropped into a detent bracket 33 shown in Figs. 2 and 5, thus effectively preventing the sash from accidentally becoming unlocked.
Another feature of my invention is concerned with mounting the swing leaf or sash i above discloses frame.
1 so that the outside of the panes can be easily cleaned from the inside of the building, and I will now describe the means by which I accomplish this result. The description how the sash 1 is pivotally mounted on the studs 9 and 10 of a sub-frame. Normally, however, the sash is prevented from swinging in the sub-frame 5 by catch means 17 so that in opening or closing the sash l the sub-frame and sash act as a unit just as if the sash itself were hinged to the When it is desired to wash the winthe sash is opened to its widest position. The catch 17 is released, thus freeing the sash 1 and allowing it to be swung on the studs 9 and 10 to a position shown by the dotted lines in Fig. 5. There is then ample space between the sash 1 and the window frame 2 to allow the outside of the panes to dow panes be conveniently reached for cleaning. As shown in Fig. 5, the pivotal axes as defined by the studs 9 and 10, and by the pivot 28 are so spaced that the stay 19 serves as a stop against which the outer and lowermost flange of the sash 1 abuts when the latter is pivoted on the studs 9 and 10 to be cleaned, or to regulate the ventilation. Fig. 5 also clearly shows how the sash, when in a position shown by the dotted lines, acts as a deflector to direct air currents into the building. Thus my novel arrangement just described serves a double purpose. Figs. 2 to 5, inclusive, show how screen panels may be secured on the inside of the frame. The casing 2 1 is provided with a projection 3 1, which cooperates therewith to support the screen or storm sash at the bottom and hold it in close contact and flat against the inside of the window frame. At the top, any suitable releasable fastening means 41 may be employed to hold the screen or storm sash flat against the frame, such as screws, or rotating, sash catches, still leaving it easily removable for cleaning purposes. In place of the removable screen frame, grooved strips may be fastened to the sash frame 1 so as to guide. a roll-up screen, the box for which can be attached to the top of the frame 1, as shown at 12 in Fig. 2.
. The absence of all operating handles or the like, except the stay 19 which extends through the bottom rail of the frame and thus under the screen frame, allows the swing leaf or sash to be closed and locked, or unlocked and opened, without touching the screens, and with only one hand in a single motion.
If desired, turn buckles 36 and 37 may be provided in either or both of the rods 27and 29 by which the positionof the pawls 28 and 30 may be adjusted. Notches 38 and 39 may be provided in the flanges 81 and 32 of the window frame, although not necessary, to allow the pawls to clear when the sash 1 is closed. The tongue 40 is shown as slightly bent forwardly of the frame, and this is for the purpose of fitting more nearly perpendicularly within the notches 21 in all open positions of the sash so that the sash is held in position without rattling.v
In cases of double casement window s having two swing sashes it is not essential that my sub-frame construction be employed, although its use in such situations may be of considerable, advantage'in directing the air to secure better ventilation. The latching mechanism which I have disclosed can be applied to the edge of either single or double swing sashes, and in the latter case where the edge of one sash closes over the edge of the two or more swinging sashes to provide each Ti with the sub-frame and locking structure described above, I have, however, described only one sash, the others being'identical therewith. I have, moreover, shown the other sash as carried on hinges 51 and 52 secured to the frame 2 and as provided with a stay or operator 19 corresponding exactly with the stay or operator 19 described above, there being also a spring pressed plunger assembly 24 identical with that indicated byQ in Fig. 6 and described above. It is seen that sash 50 is closed first and that, by virtue of the overlapping flange 53 of the sash 1, when the latter sash is closed and locked both are securely closed, both stays being retained by the detent bracket 33, as shown inv 9.
It is to be understood, of course, that my invention is particularly applicable to windows having only a single swing leaf or sash, in which case it is desirable to provide the sub-frame and associated structure to allow for easy cleaning; It is to be understood, also, that while I have shown my invention as embodied in metal windows having the usual steel channel sections, it is just as applicable to windows having wood sashes and frames.
It is to be understood, further that while I have described only the specific embodiment of my invention illustrated in the accompanying drawings, it will be apparent that many modifications therein may occur to those skilled in the art without departing from the spirit of this invention, and I desire, therefore, that the same be limited only by the prior art or by the scope of the appended claims.
