Fig. 9 is a sectional view taken substantially through V9--9 of Fig. 8, showing the window control device in plan.

The window control device is illustrated in Figs. 1

` through 3 and 5 through 9 as adapted to a typical metal window structure.

mA typical or conventional window structure includes Va metal window frame 1 formedofextruded metal so vas to denne an interior, inwardly directed lip 2connected by a web 3 toan exterior, outwardly directedlip r4.

"ice

2 The window frame is 'intended to be mounted within a window opening.

Fitted within the window frame 1 is a window sash S which is likewise provided with `an interior inwardly directed lip 6 connected by a web 7 to an exterior, outwardly directed lip 8. The lips of the window sash 5 bear against the lips of the window frame l when the window sash is in its closed position, such as shown in Figs. 1, 2, and 3. The window sash receives'a windowl pane 9 which is heldin place against the lip 6 by a retainer member 10.

The window sashv 5 is pivotably connected to the window frame by various hinges or mounting devices, not shown. One such type of mounting device is shown in Patent No. 2,784,459, lissued March l2, 1957. The window sash may be mounted so as to pivot about a horizontal axis or about a vertical axis, in which case the window control device is mounted at the top or bottom of the window, or at the side thereof, as the case may be. It is customary to mount on the interior side of the windowV frame 1 a window screen sash 11 containing a window screen 12. The`window screen sash is in the form of a thin metal frame which overlaps the margin of the lip 2.

The window control device includes a sash bracket 13 which is secured to the window sash 5 at one side thereof between the web 7 and the corresponding outwardly directed lip 8 so that whenthe window sash is in its closed position the `sash bracket 13 is disposed beytween the web 7 andthe Web 3. y

The sash bracket 13 includes a pair of right angularly disposed

flanges

14 and 15, confronting, respectively, the web 7 and lip 8. One or both of these flanges may be secured by means of rivets or screws. The sash bracket isv divided lengthwise by partitions 16 having slots 17 therein which slidably receive a cross bar 18.

The cross bar 18 is secured to or journals a link member 19, which extends outwardly from the sash bracketl 13. The cross bar permits pivotal movement of the link member about an axis parallel to the side of the Window sash 5 on which the sash bracket is mounted as Well as limited sliding movement.

The ends of the partitions 16 remote from the flange 15 are joined to partial walls 20 which in turn are joined to partial partitions 21 directed toward the anges 15 parallel to the partitions 16. The partitions 16, walls 20, and partial partitions 21 form housings or pockets for compression springs 22 anchored to the extended ends of the cross bar 18 so as to urge the cross bar and link member 19 toward the flange 15, that is, tow-ard its retracted position. j

The extended end of the link member 19 is divided to 'form a yoke 23fwhich is provided with a journal rivet 24 defining an axis at right angles to the cross bar 18. The yoke 23 receives a push bar 25 which is journaled by the rivet 24. The push bar 25 is in the form of'an arcuate ystrap and is slidably received in a push sleeve 26 which is also arcuately curved.

The push bar 25 is provided near its end remote from the yoke 23 with a push button 27 backed by a leaf spring 28 and arranged to enter a perforation 29 provided inthe push sleeve 26. In the construction shown, a perforation 29 is provided near each end of the push sleeve 26 so that the push bar 25 may be latched in a telescoped or retracted position relative to the push sleeve, as shown in Figs. l, 2, and 7, or in an extended position relative to the push sleeve 26, as Ashown in Figs. 8 and 9. The extended 'end of the push sleeve 26 is. provided with a handle 30 which may terminate in a linger loop.

One side of the inwardly directed lip 2 of the window frame 1 is provided with an, aperture lin alignment with the sash bracket 13 over which is mounted a guide bracket 31.Y The guide bracket is provided with lateral ears which receive screws for attachment to the window frame. The'g'uide bracket may have a projection 32 whichfits within and lines the aperture. s f' The guide bracket 31 is provided with arectangular slot 33 which slidably Vreceives the push sleeve 26 and push bar 25. The interior end'of the slot 33, that is, the end remote from the projection 32, is preferably ared as indicated by 34. f

The link member 19 has suicient length that when the window sash 5 occupies its closed position, such as shown in Figs.' l, 2, and 3, thepush bar 25 and push sleeve 26 may be pivoted about the axis of the journal rivet 24, so that the push barmay be forced to a position parallel with the window frame 1 by fulcruming the push bar 25 over a margin 35 of the guide bracket 31. This action draws the window sash inwardly against the window frame, against the compression of the springs 22.

A latching bracket 36 is provided at one side of the guide bracket 31 and is provided with a hook end 37 whichV retains the push sleeve 26 in its laterally extending or locking position. Y

Operation ofthe window control device is at follows:

When it is desired to open the window sash 5 from the position shown in Figs. 1, 2, and 3, the push sleeve 26 is first depressed slightly to disengage the hook end 37 of the latching bracket 36, and then rotated about the pivotal axis of the push bar 25 in alignment with the link member 19. The push bar and push sleeve are then pushed outwardly through the guide bracket 31 so as to swing the window sash 5 toward the position shown in Fig. 7.

The extremity of the push sleeve 26 forms a shoulder 38 which engages the margin of the slot 33 so as to hold `the window sash extended. If it is desired to extend the window sash further, the button 27 is initially depressed and the push sleeve pulled outwardly relative to the push bar 25 until the button engages the other perforation, whereupon the push bar and push sleeve are forced through the slot 33, pivoting the window sash to the position vsuch as shown in Figs. 8 and 9. In this case, also, the shoulder 38 engages the slot 33 to hold the window sash in its extended position.

To retract the window sash 5V it is merely necessary to disengage the shoulder 38 from the margin of the slot 33 and pull the push sleeve 26 inwardly. When the window sash reaches its closed position the push sleeve is then displaced angularly relative to the link member 19. When the push sleeve 26 is in its extended position, the button 27 is depressed to permit telescoping of the push sleeve 26 over the push bar 25 are pivoted to the position shown inFigs. l, 2, and 3, causing the push bar 25 to fulcrum over the margin 35 of the guide bracket 31 and draw link member 19 in opposition to the springs 22 whereby the compressive forceA of the springs urges the window sashl 5 into a snug sealing engagement with the window frame 1. Y

- Reference is now directed to Fig. 4. This construction is essentially the same 'as the previously described structure. However, the guide bracket 31a may be modified so as to be secured to the top of a wooden sill 39, and the wooden window sash designated 40 may be provided with a recess or pocket to receive the sash bracket 13. The operation of the window control device as installed on a wooden window frame and window sash s identical to the operation of the control device as mounted on a metal ,window frame and window sash.

.ing a window frame yand a pivotable window sash, com- It is sometimes desirable, in order to facilitate cleaning of the window, that control device be disconnected and permit movement unrestrained by the control device. This can be readily done by depressing the push button and completely push bar. f Y l p It will be observed that the push bar 25 may be pivoted withdrawing the push sleeve from the in either directionrelative to the guide bracket 31 for either left or righ mounting of the window control device.

While particular` embodiments of this invention have been shown and described, it is not intended to limit the same to ythe exact details of the; constructions set forth, and it embraces such changes, modifications, and equivalents of the parts and their formation and arrangement as come withinY the purview of the appended' claims.
