7 Claims. (Cl. 20-53) This invention relates to a window having a pivoted sash and particularly to that type of window which has a sash pivoted on a vertical axis midway between the stiles.

In windows of this type the sash is so mounted and so constructed that is capable of being rotated about its pivots to come to rest in the frame after a rotation of either approximately 180 or 360.

Obviously a push from the interior of. the room on either side of the pivotal axis of a sash of this type will cause the sash to open and this ability makes it possible to rotate the sash 180 so that both ofV its faces may be cleaned without the cleaner leaving the room or extending himself from the Window opening. It is also possible completely to rotate the sash so that either face may be used on the outside of the building.

Since, in a window of this type, the space between the frame and the sash must be heavily weather stripped, it is at times desirable to reverse the position of the sash by rotating the same 180 to adapt the weather stripping to a tighter fit during use.

In a window of this pivotal type and especially in windows having large sashes, it is necessary that the sash be securely locked and incapable of accidental unlocking to obviate the possibility of a person unintentionally opening the sash as for instance by leaning lagainst it on one side of the pivotal axis.

lt is an object of the present invention to provide a window having such a sash as set forth above and wherein locking devices are provided which are incapable of accidental unlocking and opening and which are rendered inoperative to lock the sash by sequential manual operations.

More specifically, it is an object of the invention to provide such a window wherein, when the sash is swung closed from an open position, it automatically will be ,locked at both window frame jarnbs and when it is desired to open the sash an act of unlocking the automatic lock will at the same time bring into operation a secondary locking device which, while it will permit the sash to swing slightly on its pivots toward a completely open position, will prevent its swinging only to such an extent that it will be impossible for one operating the window to fall from the window opening.

With these and other objects in view the invention comprises the combination and arrangement of parts illustrated in the drawings, described in the specification and recited in the claims.

In the drawings which disclose the preferred embodiment of the invention,

Figure l is an elevational view of the inside of a window constructed in accordance with my invention;

Figure 2 is a horizontal sectional view on line 2-*2 of Figure l, looking in the direction of the arrows;

Figure 3 is an enlarged fragmentary horizontal sectional view on line 3--3 of Figure l looking in the direction of the arrows;

Figure 4 is a vertical sectional View taken in the plane a. c 2,812,557 Ice Patented Nov. 12, 1957 of line 4 4 of Figure 3 looking in the direction of the arrows;

Figure 5 is a perspective View of the latch operating cam, its supporting barrel and operating key member, the same being shown in position vertically reversed from the positions shown in full lines in Figure 4 in order more clearly to show the constructions;

Figure 6 is a fragmentary perspective view showing the construction of and the relation of the strike plate to the window frame jamb.

The invention comprises a sash which is mounted in the frame of the window', as described in the forepart of this specification, and, as disclosed in the drawing, in combination with an automatic locking arrangement at each jamb of the frame which comes into operation automatically as the sash reaches a closed position and which, when rendered inoperative to lock the sash, will permit it to rotate about its vertical pivotal axis and in combination with a manually operable device for rendering the automatic locking arrangement inoperative and for performing the additional function of preventing the sash from swinging outwardly except to a limited extent until a deliberate manual sash releasing operation has been accomplished.

In thel drawings a window frame having a header 1, a sill 2 and jambs 3 is disclosed. ln this frame a sash, having upper and lower rails 5 and 6 and stiles 7 and is mounted to rotate horizontally on vertical pivots 9 and 10 which are carried by the header 1 and sill 2 and have bearings in the upper and lower rails 5 and 6 of the sash. The sash is sufficiently smaller in dimensions than the window opening of the frame to permit it to be rotated 360 and the spaces between the sash and the frame are weather sealed by weather sealing members 11 which are carried by the sash and are preferably of the resilient and compressible type and of such material as neoprene or the like. Each edge of the sash carries, preferably, a pair of spaced weather sealing members so that, regardless of whether or not the sash is in one position or has been rotated to occupy a position 360 from the original, the space between the sash and the frame will be ,sealed at the outside as well as the inside of the Window with the result that the weather sealing members not only deter the ingress of the weather into the room but also protect the operating parts of the window locking mechanisms.

In order that the sash may be locked automatically when it is swung to a closed position and will positively lock the sash in such position, I have provided the following mechanism: each sash stile is provided with a spring projected latchabolt which is adapted, when the sash is closed, to project into an opening in a strike plate carried by the adjacent jamb of the frame when the sash is moved in a horizontal direction. This latch-bolt 12 is mounted for longitudinal horizontal movement within a housing which is carried by the vertical stile of the sash and is normally moved outwardly by a spring 14 which is located within the housing and projects into a bore 15 in the latch-bolt 12, being normally under suicient compression to move the end of the latch-bolt out wardly from the sash stile.

This outward movement of the latch-bolt is limited by engagement of a shoulder 16 on the bolt with a complemental shoulder 17 on a guide 18 which is secured to the stile by suitable means such as bolts 19. It is to be noted that this guide has an extended portion 20 which tends to strengthen the bolt and prevent its displacement when undue force is applied to the sash.

The adjacent iamb is provided with a strike plate 21 which extends across the face of the jamb and is provided with divergent cam surfaces 22 at its edges. This strike plate is secured to the adjacent jamb by suitable fasteners 23 which engage ears 24 on the strike plate that extend through a channel in the face of the jamb.

This strike plate is provided with an opening 26 which is adapted to receive the end of the latch-bolt 12 when the sash is closed to effectuate the locking of the sash in its closed position.

Thus, when the sash is open, the ends of the latch-bolts 12 will project to their greatest extent from the stiles of the sash and whenthe sash is moved to a closed position the ends of the `bolts will engage the cam faces 22 of the strike plates with the result that the latchbolts will be moved inwardly against the action of the springs 14 until they align with the openings 26 at which time the springs automatically will project the latchbolts into the openings and thus lock the sash.

In order that the latch-bolts 12 may be moved into` the sash stiles against the action of the springs 14 and out of the openings 26 to thus unlock the sash and permit it to be moved as desired about its pivotal axis, I have provided the following mechanism: a cam 27 which is rigid with and preferably integral with a barrel 28 is mounted within a chamber 29 formed in the jamb by the strike plate 21 and the ears 24. On one end of the barrel 28 is a bearing member 30 which pivots into and is capable of rotating in a bearing 31 in a plate 32 which is secured to the jamb by the bolts 23, as illustrated in Figure 6 of the drawing. A complemental bearing 33 is provided in the inside flange of the jamb and receives a bearing member 34 on the barrel 28. This cam 27, when inoperative, is in the position disclosed in Figure 4 of the drawing in solid lines but it may be rotated on the bearing members and 34 downwardly into the dotted line position shown in this figure. As it is thus rotated, it engages the end of the adjacent latch-bolt 12 and moves the same outwardly beyond the opening 26 in the strike plate 21 against the action of the spring 14. As will, be seen, in Figures 3, 4 and 5, the horizontal dimensions of this cam 27 (Figures 3, 4 and 5) are such that when the cam is rotated into the dotted line position shown in Figure 4 and extends into the opening 26 it will substantially close said opening, horizontally at least, to such an extent that the latch-bolt, as the sash is rotated, will be excluded from entry into the opening and the sash may thus freely be moved toward an open position.

In order that these cams on the opposite sides of the window may manually be operated to move the latchbolts against the actions of the springs 14 and to subsequently withdraw from the openings 26, I have provided combined cam operating and sash retaining members, one for each cam when used with a sash which is capable of 360 rotation. Each of these members 35 comprises a shank 36, a key portion 37 and a sash engaging member 38 which is preferably of rubber, neoprene or some similar material. The key portion of each member is adapted to enter the opening 39 and the slot 40 of one of the barrels 28 and to be limited in the extent of its entry by the bearingy member 30. When the key portion is thus engaged and the cam 27 is in its inoperative position, the shank 36 and the sash engaging `member 38 are located within the room adjacent the face of the inner flange of the jamb with the shank 36, the sash engaging member 38 and the key 37 extending upwardly.

When it is desired to open the window the shanks 36 and the sash engaging members 38 of the cam operating and sash retaining members 35 are rotated from the full line position shown in Figure l and the dotted line position shown in Figure 2 to extend toward each other substantially in horizontal positions as shown in dotted lines in Figure l and in full lines in Figure 2. When these members are rotated into these horizontal positions, the camy 27 will be moved downwardly into the dotted line positions shown in Figure 4 of the drawing and any such movement will force the latch-bolts 12 out of the openings 26 lin the strike plates 21. The movement of the cam member 27 from the full line to the dotted line position shown in Figure 4 is limited by the engagement of the abutment 27' with the window frame. The members 35, when released from manual control, will be retained in their horizontal positions as a result of the pressure of the springs 14 exerted through the latch-bolts upon the barrels 28 in line with the axes of said barrels.

When the latch-bolts have been forced from the openings 26 in the strike plates 21 `the sash is released for movement and may be partially rotated on the pivots 9 and 10 to the positions shown in full lines and dotted lines in Figure 2 by the exertion of a manual force on one side of the sash pivot. However, the extent of this movement is only such as to move the latch-bolts out of alignment with the openings 26 in the strike plates as, at this time, the stile at one side of the sash will engage the sash engaging member 33 on the shank 36 on the opposite side of the pivot of the sash.

In order that the window sash may be rotated through substantially or substantially 360 it is necessary for the operator to remove the sash engaging member 38 which is at that time engaged by the stile out of the path of movement of the sash. When thus removed from the path of movement of the sash, the sash engaging member 38 will permit the sash to be pivotally moved substantially 180 on its pivots but before it can be moved 360, the other of the two sash engaging members 3S must be manually moved out of the path of travel of the sash.

When the two members` 38 have thus been moved out of the path of travel of the sash, they will again extend upwardly and the cams 27 will be restored to their inoperative positions, extending upwardly as illustrated in full lines in Figure 4 of the drawing.

With the members 38 in their upwardly extending positions out of the path of movement of the sash, the latchbolts 12 automatically will engage in the openings 26 of the strike plates 21 under the action of the springs 14 when the sash moves into the plane of the window frame and the bolts align with the openings.

Thus it'will be seen, that, even after the latch-bolts have been disengaged from the strike plates, it will be impossible to swing the sash on its pivots suiiiciently to permit a person accidentally to fall from the window opening. To complete the release of the sash, the sash arresting members 38 mustmanually be moved out of the path of travel of the sash, and, when the sash is of considerable width, it is necessary for the operator to rst move one of the members 38 and to then move to the other side of the window to move the other of the two members 38.

This sequential unlocking of the window greatly minimizes the chance of a person falling from the windev.l opening by leaning against one side of the sash.

It will be noted that the bearing opening 33 is of keyhole form, being provided with a downwardly extending slot 33' (Figure 6) to permit the key portion 37 of the key member 35 to pass therethrough when the latter is withdrawn from the window frame. This key portion 37 aligns with this slot 33 only when the cam Z7 is in the inoperative upwardly extending position shown in Figure 4 in full lines, at which time the bolts 12 will lock the sash in closed position. This insures the key member against withdrawal when the bolts 12 are in unlocking positions and the sash is free to move on its pivots.

I have illustrated and described the preferred embodiment of my invention, but it is to be understood that various modifications in the structure disclosed may be made without departing from the spirit of the invention or exceeding the scope of the claims and I, therefore, do not wish to be limited to the precise structure of the disclosed embodiment but only to the extent that limitation is made necessary by the claims when interpreted in the -Ilight of the specification and drawings.
