2 6 Claims. (CI. 20-53 This invention relates to a device for holding the lower edge of a storm sash or the like.

An object of this invention is to provide a readily operated device which can hold the lower edge of a storm sash'open or closed.

A further object of this invention is to provide a sash holder which includes an elongated main arm pivotally mounted on the sash which can swing between an open position in which the elongated arm engages a stud member which is attached to the casing of the window and holds the sash open and a closed position in which a track on the elongated member adjacent the pivot thereof engages and grips the stud to hold the sash closed.

The above and other objects and features of this invention will in part be apparent and in part be obvious to those skilled in the art to which this invention pertains from the following detailed description, and the drawing, in which:

Figure l is a view in vertical section of a window opening having a double hung window equipped with a storm sash held in open position by a pair of sash-holding devices constructed in accordance with an embodiment of this invention;

Fig. 2 is a view in section taken on the line 2--2 in Fig. 1, one of the sash-holding devices being shown in r'eleasedrposition in dotted lines;

' Fig. 3 is an enlarged fragmentary view in horizontal section showing thedevice in position for holding the storm sash in closed position;

' Fig. 4 is an enlarged fragmentary view in section taken along the line 4-4 in Fig. 3;

: Fig. 5 is a view in section taken on the line 55 in Fig. 4; Fig. 6 is a view in section taken on the line 6-6 in g.

; Fig. 7 is an enlarged fragmentary view of one end of the arm of the device shown in position for holding the storm sash in open position;

Fig. 8 is an enlarged fragmentary view of a portion of the device shown with the storm sash closed preparatory to locking the sash in closed position; and

- Fig. 9 is a fragmentary view in horizontal section showing a screen equipped with a similar device.

In the following detailed description, and the drawing, like reference characters indicate like parts.

In Figs. 1 and 2 is shown a window opening 10 provided with a casing having

side members

12 and 14, a stool 16, and a lintel 15. Upper and lower sash are indicated at 17 and 18, respectively. The upper and lower sash run in

channels

19 and 21 in the usual manner. The outer guides for the track of the upper sash are formed by

molding strips

22 and 23 which are ordinarily referred to as blind stops. A storm sash 24 having a glass sheet 25 is hinged to the lintel by hinges 26. The storm sash may be held in open position, as shown in Figs. 1 and 2 by sash-holding devices indicated at 27 and 28.

Details of construction of one of the sash-holding debe used in connectio n rwith a window Patented June 2, 1959 vices are shown in Figs. 3 to 8 inclusive. As shown most clearly in Figs. 4 and 5, the sash-holding device 27 includes an elongated main arm 29 which is pivotally mounted on a hinge plate 31 by a pivot 32 (see Figs; 3 and 4) adjacent one end of the arm 29. The hinge plate 31, in turn, is pivotally attached to another hinge plate 33 by a pivot pin 34. The plate 33 is rigidly attached to a side frame member 36 of the storm sash 24. As shown, the arm 29-swings about its pivot32 in a plane parallel to the hinge plate 31.

When the storm sash is in open position, the arm 29 engages a stud member or screw 37 having an enlarged head. The stud or screw 37extends into the blind stop 22, 'as shown most clearly in Figs. 3 and 7. When the storm sash is open, the head of the stud 37 is received in a bayonet slot 38 adjacent the free end of the main arm of the device. A catch 41,- which is pivotally attached to the main arm, is provided with radial grooves 42 one of which receives the stud member 37 to hold the arm in place with the shank of the stud member in the narrow portion of the bayonet slot.

When the storm sash is to be closed, the'catch 41 is swung away to release the stud member 37. An inwardly directed flange 43 on the main arm can be grasped to swing the main arm inwardly to the position 'shown in dotted lines in Fig. 2 at which the main arm is released from the stud member. The main aim of the device 27 may be released in a similar manner. Then the storm sash is drawn to theclosed position indicated'in' Figs. 3, 4 and 5. As shown in Fig. 1, the distance of the stud member from the lintel is equal to the'distance from the upper edge of the storm sash to the pivot 32 of arm 29 so that, when the storm sash is closed, the pivot 32 and the stud member 37 are in registry; A track comprising angle-

shaped flanges

44 and 45 is mounted on one side of the main arm in registry withthe pivotthereof. The

flanges

44 and 45 are spaced to provide a slot 46 therebetween. When the sash is drawn to the position shown in Fig. 8, the

flanges

44 and 45 register with the screw 37 and the screw is received in the slot 46 between the flanges with the screw head being in registry. with the pivot of the main arm 29. As shown, the width of'the slot 46 is greater than the diameter of the shank of the stud member, but less than the diameter of the head thereof so that the stud member is held thereby. Then the arm may be swung downwardly to the position shown in Figs. 3, 4 and 5 in which the sash-is latched closed. As the arm swings, the flanges of the track swing therewith to the Fig. 5 position at which the flange 45 can engage the stud member 37 to hold the storm sash closed. As shown in Fig.- 6, when themain arm is swung down to this position, the main arm is in alignment with the blind stop 22. As shown, the main arm is narrower than the blind stop so that the device does not interfere with operation of the Window sash. As, shownmost clearly in Figs. ,3 and 4, the hinge plate 33 is attached to the frame of the storm sas'h in alignment with the

track flanges

44 and 45 so that a minimum amount of space is taken up by the sash holding device. I

The device has been described to this point with relation to a storm sash; however, a similar device may screen. In Fig. 9, a device 47 is shown; If de'sired,"hinge plates 49 (only one of which is shown) may be attached to the sides of the screen frame. These hinge plates 49 may be identical in construction with those attached to the storm sash so that, when the hinge pins are withdrawn, the main arms and associated parts of the devices may be used both with a storm sash and with a screen.

The devices described above and illustrated in the drawing are subject to structural modification without departing from the spirit and scope of the appended claims,

described my invention, what ,I cla m as new, and desire to secure by Letters Patent is:
