ATTORNEY Patented June 4, 1940 Application December 18, 1937, Serial No. 180,651
Renewed October 18, 1939 Claims.
The invention relates to sash locks and sash holding devices, and has for its object to provide a device of this character wherein a sash may be frictionally held at Various elevations in close binding engagement with a parting strip or outside strip'for excluding weather, the sash lock in closed position, or held in position where it will have a limited range of movement for ventilating purposes, and at the same time prevent unauthorized persons from entering a building through the window.
A further object is to provide a bevelled inside strip carried by the window frame and an inwardly and outwardly movable spring actuated bevelled jamming strip carried by the sash and adapted to be jammed against the bevelled inside strip and the inner side of the sash for holding the sash frictionally and for forming a weather proof connection between the outer side of the sash and the outside or parting strip, according to the sash the device is applied to.
A further object is to provide a pivoted member on the sash and extending downwardly and terminating in a lip adapted to move by gravity through an opening in the jamming strip into engagement with the inner bevelled side'of the inside strip and adapted to ride on the inside strip as the sash is moved upwardly and downwardly.
A further object is to provide the inner side of the inner strip with an elongated slot terminating at its lower end in an enlarged portion, through which the gravity actuated pivoted dog end passes so it will enter the elongated slot and limit the upward and downward movement of the sash for locking the sash against movement beyond its range of movement in the slot, for instance when ventilated.
A further object is to provide an enlarged portion to the extreme lower end of the ventilating slot, and into which the dog lip is received after passing a spring catch, thereby allowing the sash to be locked in closed position.
A further object is to mount the jamming strip slidably on a plate carried by the face of the sash as well as pivotally and to provide finger gripping members on the plate and the jamming strip member whereby the jamming strip may be moved out of jamming engagement against spring action.
A further object is to make the jamming strip V-shaped in cross section and to dispose an arm of the tensioning spring therein in the path of the lip of the pawl for providing the tensioning action and at the same time allowing the spring end to be moved out of the path of the gravity actuated pawl, so its lip will engage the outer side of the spring arm, thereby preventing the locking of the sash against movement when a person is working outside the window.
A further object is to pivotally and slidably mount the jamming strip on the sash carried plate so it will rockably coincide with the bevelled surface of the inside strip to facilitate the breaking of the jammingaction and insuring a positive jamming action throughout its length.
A further object is to provide the lower end of the sash carried strip with 9. lug, which, upon extreme disengaging movement of the jamming strip, will engage the jamming strip and allow the jamming strip to assume a parallel relation to the sash strip upon disengagement.
With the above and other objects in View the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.
In the drawings:
Figure 1 is a perspective view of a portion of a sash and window frame, showing the device applied thereto.
Figure 2 is a horizontal sectional View taken Figure 6 is a horizontal sectional view taken on line 6-6 of Figure 4.
Figure '7 is a horizontal sectional View taken on line 'l-l of Figure 4, and showing the dog at the start of the locking operation.
Figure 8 is a horizontal sectional view taken on 1 line 8-8 of Figure 4, and showing the locking dog in sash locking position.
Figure 9 is a view in elevation of the jamming strip and the sash carried strip, showing the jamming strip in partial retracted position whereby upon further movement it will be tilted to parallel relation to the sash strip.
Figure 10 is a detail perspective view of the lower ends of the sash strip and jamming strip shown in Figure 9.
Referring to the drawings, the numeral l designates the side rail of a conventional form of window sash, and 2 the side of a window frame. Although the device is applied to the upper and lower sash and to both sides thereof, it will only be described in connection with one side of one of the sash.
The sash is slidably and loosely mounted between the parting strip 3, which is formed from sheet material and is V-shaped as clearly shown in Figure 2, and the bevelled inside strip 4, which is V-shaped in cross section and has its bevelled side 5 inclined inwardly at an acute angle to the sash. The parting strip 3 is provided with a flange 6, which is secured to the window frame by means of screws 1. The inside strip Q is provided with a flange 8, which is secured to the window frame by means of screws 9 and the sash is adapted to be moved upwardly and downwardly between the parting and outside strips.
Secured rigidly to the inner face of the sash stile i is a stile strip if] having a vertical flange H in a rabbet 12 in the side of the stile. Stile strip H] is provided with an extension plate l3,
" which is secured to the stile face by means of screws M. This plate 13 is rigidly held and provided with a finger engaging member l5. Plate 13 is provided with a lug It, on which is pivotally and rockably mounted the extension plate ll formed integral with the V-shaped jamming strip 18. It will be noted that when the operator grasps the finger engaging members l5 and E9, and forces them towards each other, the jamming strip l8 will be pulled out of jamming engage- 7- ment between the stile strip ill and the portion 5 of the outside strip, thereby allowing the sash to be moved upwardly or downwardly. The jamming strip i8 is normally forced towards the inside strip by means of a looped torsion spring 20, one arm 2! of which engages the outer side of the headed lug it in the annular channel 22 thereof, and the other arm extends downwardly within the chamber of the jamming strip l8 and is designated by the numeral 23. Arm 23 terminates in an angularly disposed arm 24, which engages in the bottom of the chamber of the jamming strip. Plate 5'! is provided with an elongated aperture 25, thereby allowing inward and outward movement thereof under the influence of the spring, or when the operator grasps the ringer engaging members 15 and IQ for a sash moving operation. It will be noted that when the jamming strip is in jammed position, as shown in Figure 2, the stile I will be forced into close engagement with the inner side of the parting strip and the jamming strip will be in close engagement with the outside strip, thereby forming a holding means for holding the sash at various elevations and also a weather proof connection between the parts.
It will be noted that the finger engaging members l5 and is are below the pivotal point and upon a sash releasing operation the lower end of the jamming strip IE will be first pulled out of jamming position, thereby allowing the easy manipulation oi the jamming strip. This is clear as shown in Figures 9 and 10. As the pressure on the finger engaging members 15 and I9 continues, the lower end of the jamming strip i8 will engage the lug 26 carried by the lower end of the stile strip is and stop the outward movement of the lower end of the jamming strip and at which time the upper end of the jamming strip will be progressively released, hence it will be seen that a minimum amount of exertion will be necessary to release the jamming strip.
At times it is desirable to adjust sash for ventilating purposes, but in positions whereby unauthorized persons can not pass through the window, usually a range of adjustment is desired according to weather conditions. It is also desirable to provide means for locking the window closed, so unauthorized persons can not raise the same. To accomplish these results a gravity actuated pivoted dog 2'! is mounted on. the lug I6,
and it will be noted by referring to Figures 1 and V 2 that the pivotal point of the lug is to the outer side thereof soits weight, under the influence of gravity, will normally swing the downwardly and outwardly extending arm 28 thereof outwardly and into the chamber of the jamming strip l8, which jamming strip is provided with an aperture 29 in its angularly disposed portion, and" through which the arm passes with'lts lip 30 in sliding engagement with the angularly disposed side 5 of the outside strip. The position is better shown at a in Figure 4 and in the sectional I view of Figure 5. As the sash is moved upwardly and downwardly the lip 30 rides on the portion 5.
When it is desired to adjust the window for ventilating purposes the sash'is moved downwardly, reference beinghad to Figure 4, until the lip 30 reaches the recess 3! and at which time the gravity actuated pawl 21 swings outwardly so the lip 35 will pass through the recess 3! and into the vertically elongated ventilating slot 32, and then the sash can be moved upwardly to the desired adjustment, for instance as shown] by the lip position b, Figure 4. It will be noted there is a wide range, of adjustment for ventilating purposes, however this slot is preferably of a length whereby in all positions thereof, it will prevent a person from entering the window above or below the sash.
When it is desired to positively lock the window in a closed position the lip .30 is moved down-- wardly after it enters the recess 3! asv clearly shown at c, then upon further downward movement of the sash, the lip will pass the shouldered.
the sash is in closed position, the recesses 34 of 1 the inside strip and the recess 29 in the jamming strip will be in registry and at an outward and inward inclined angle, therefore it will only be necessary for the operator to force the finger engaging member l9 towards the'finger engaging member l5 to release the jamming strip and move the lip through said registering apertures,
34, therefore it will be seen that means should be provided for preventing the sash from automatically locking under certain conditions,
for instance when the windows are being washed from the outside. To accomplish this result, it will be noted that the spring arm 23 is inwardly offset as clearly shown in Figure 1, and it can be easily flexed outwardly out of the path of the lip 3 by the fingerof the operator so the lip will be disposed on the opposite side of the arm 23, and said arm will hold the pawl from automatically locking during the movement of the sash upwardly or downwardly under the above conditions. After the window Washing operation, the
parts are restored to their position as shown in Figure 1.
From the above it will be seen thata sash. fas- 7 tening and holding device is provided which may be easily manipulated, the sash adjusted for ventilating purposes and the sash positively locked when desired. By providing the jamming strip a weather proof connection is provided which will form a seal on the inside of the sash, as well as force the outer side of the sash into close binding engagement with the parting strip for sealing'at this point. It will also e seen that upon release of the device, the sash will be relatively loose between the strips thereby allowing the sash to be easily manipulated, and by the bevelled engagement of parts any wear will be taken up by the device.
It will be noted that when the operator grasps the finger engaging members 15 and i9 between the thumb and forefinger, the knuckle of the forefinger may be placed in engagement with the knurled portion 36 of the pawl 2'! for pivotally moving said pawl outwardly and releasing the same, therefore it will be seen that the operator can easily manipulate the pawls of sash holding devices at opposite sides of the sash. The knuckle engaging knurl 36 does not extend a material. distance from the outer face of the pawl 21, hence it will be seen that when the window is adjusted for ventilating purposes, an instrument can not be used by an unauthorized person to disengage the pawl when the pawl lip is moved downwardly to the recess 3|.
To further prevent an unauthorized person from manipulating the pawls 21 when the sash is in ventilating position, the plate I! is provided with a chambered guard 31, into the chamber 38 of which the inner side of the pawl 2'! extends and is disposed in a manner whereby it would be impossible for an unauthorized person to utilize a pair of hooks, connected by a contractible member, for instance a rubber band, to place the hooks over the pawl arms and allowthe contractible member to pull the pawls and their lips out of the apertures 3| at the bottom of the ventilating position.
