WINDOW LOCKING AND ANTIRATTLING DEVICE Filed April 28, 1952 JAE' 'ETIEUE 21 lanazswfiuzzziis fli'iamays United States Patent WINDOW LOCKING AND ANTIRATTLING DEVICE Leland B. Watts, Lethbridge Alberta, Canada ApplicationApril' 28, .1952,Serial No. 284,793

3 Claims. (Cl.-292213) The present invention relates to a v simple device for locking aloosely fittedwiridow sash'which is vertically slidable in a window .ca sing. llhe device also prevents rattling of, the window sash with respect to its casing.

The'windows of many cottages,'ficabins, and. low-cost houses are not counter=balanced, and often merelyconsist of a stationaryupper section and a movable lower sash whichis mounted for vertical sliding in the window casing. Since the slidable sash is usually quite loosely fitted in the window casing, some precautions must be taken against rattling of the window in its casing; and since the sash is not counter-balanced, some means is required for holding the window up when it has been opened. The device of my invention fulfills both these functions, and additionally serves to lock the window in its fully closed position, thus eliminating the need for any additional locking means.

My invention broadly resides in a device for locking in an open or in the closed position and for preventing rattling of, whether open or closed, a window sash which is vertically slidable in a window casing, the said device comprising a plate securable in said casing adjacent one of the stiles of said slidable sash; an arm pivotally mounted on said plate at a point intermediate the ends of the arm, one of the ends of said arm being bifurcated to form a pair of prongs; and a pair of rollers formed of resilient material rotatably mounted upon said arm at the end opposite said prongs, said rollers being disposed adjacent opposite corners of the end of the arm.

In the accompanying drawings which illustrate one embodiment of the invention:

Figure 1 is a view of the window locking and antirattling device of my invention showing the device holding the slidable sash of the window in the locking-closed position;

Figure 2 is a view somewhat similar to Figure 1, but shows the device holding the window in the lockingopen position;

Figure 3 is a perspective view of the device on an enlarged scale.

The Figures 1 and 2 show a part of a conventional window of the type mentioned in the second paragraph of this specification. While the parts shown will be immediately recognized by those skilled in the building and carpentry arts, they will be briefly referred to here so that the point of application of the device of my invention will be made clear to all. Reference character A generally indicates the stationary upper section of the window, and reference character B the vertically slidable lower section of the window, while reference character C has been applied to the window casing.

The stile and the meeting rail 11 of upper section A, and the meeting rail 12 and stile 13 of the slidable lower section B, may be noted in the drawings. In the 'case of the window casing C, the frame 14, stop 15,

and parting bead 16 all appear. All the elements so far mentioned in connection with the drawings are of quite conventional construction and therefore need not be described in detail.

Rigidly secured to stop of window casing C is a generally rectangular plate 16. The plate is secured to the stop by means of a plurality of screws 17. An arm 18 is pivotally mounted on plate 16 at a point 19 intermediate the ends of the arm. The arm 18 is swingable in a plane generally parallel to the major plane of plate 16. a pair of prongs which have been labelled 2t and 21.

One of the ends of arm 18 is bifurcated to provide 3 Rollers 22 and- 23 are rotatably mounted upon said arm at the end opposite the prongs 20-and 21, and disposed adjacent opposite corners .of the said end of the arm.

Arm 18 may beplaced in the neutral position in which it, is horizontally disposed, with each of its rollers 22 and 23 out of contact with the stile 13. While the arm is in this position, the lower window section B may be raised and lowered without interference from the device of the. invention. To holdxthe arm 18 in the neutral position, .I prefer to provide a pair of projections 24 and. 25 adjacent the vertical edge of plate 16 remote from stile 13. These projections are arranged to bear against opposite sides of arm 18 at a point intermediate its ends, and: thus bias saidarm to maintain the neutral position. Later on in this specification, and in the accompanying claims, I use the terms uppermost? and lowermost in connection with the prongs and the rollers. In so doing I refer to therelative positions occupied by these el'ementswhen thearm 18 is in the neutral position just described.

Arm 18*may be swung upwardly through some from the neutralhorizontalposition to a locking-open position, in which the raised sash is held open by the uppermost prong 20 hearing against stile 13 (see Figure 2). Prong 20 is resiliently held in tight engagement with the sash when in the locking-open position by the uppermost roller 22, since the resilient material thereof is distorted by pressure against the sash during achievement of said locking-open position.

Arm 18 is downwardly swingable through some 90 from the neutral horizontal position to a locking-closed position in which the lower section B is held closed by the lowermost prong 21 bearing against the stile 13, prong 21 being held in tight engagement with stile 13 by the lowermost roller 23, whose resilient material is distorted by pressure against stile 13 during the achievement of said locking-closed position.

In connection with the locking-closed of the lower window section B, I prefer to rigidly secure a plate 26 to the face of stile 13 at a point just below the point of contact of prong 21 with stile 13, when the device is in the locking-closed position. It will be appreciated that with a plate, bar, or the like, located as just described, if any attempt is made to open the closed and locked window from the outside, this attempt will be thwarted by the fact that the plate 26 will jam against lowermost prong 21. Since further upward prying of the window from the outside can only be accomplished when accompanied by rotation of arm 18 in an anticlockwise direction, as viewed in Figure 1, it will be realized that further opening of the window will be ruled out, unless the force applied is sufliciently great to actually break the locking device.

I recommend that the rollers 22 and 23 should not be freely rotatably mounted with respect to the arm 18. I prefer to so mount the rollers that considerable friction, or some other force, must be overcome when turning the rollers. I have found that where there is considerable resistance to turning of the roller 22, there is less tendency for prong 20 to dig into the wood of the stile 13 when the device is in the locking-open position. The fact that the locking device forces the stile 13 into firm frictional contact with the parting strip 16 also serves to reduce any tendency the prong 20 may have to dig into the stile 13.

I do not recommend the use of the locking device of my invention in connection with heavy, slidable window units. Exceptionally heavy windows are, in any event, usually counter-balanced. However, if for some reason, it was desired to use the device of the invention for the locking of a heavy window, a plurality of bars or plates, such as plate 26, could be secured at vertically spaced intervals on the face of stile 13, and prong 20 could be brought to bear against the lower edge of a plate or bar selected to give the desired degree of opening of the window.

What I claim as my invention is:

1. A device for locking in an open or in the closed position, and for preventing rattling of, whether open or closed, a window sash which is vertically slidable in a 0 window casing, said device comprising a generally rectangular plate adapted to be rigidly secured to one of the vertical walls of said casing adjacent one of the stiles of said slidable sash; an arm pivotally mounted on said plate at a point intermediatevthe ends of the arm, said arm being swingable in a plane generally parallel to the major plane of said plate, one of the ends of said arm being bifurcated to form a pair of prongs; and a pair of rollers formed of resilient material rotatably mounted upon said arm at the end opposite said prongs, said rollers being disposed adjacent the opposite corners of their end of the arm, the distances between each of the rollers and the point of pivotal mounting of said arm being such that one of said rollers will be forced in contact with said one stile, and the resilient material of the roller distorted by such contact, whenever said arm is swung through any appreciable angle from a neutral horizontal position, in which both rollers are adjacent but out of contact with said sash; said arm being upwardly swingable through some 90 degrees from said neutral position to a lockingopen position in which the raised sash is held open by the uppermost prong bearing thereagainst, the said prong being resiliently held in tight engagement with the sash by the uppermost roller whose resilient material is distorted by pressure against the sash during the achievement of said locking-open position; said arm being downwardly swingable through some 90 degrees from said neutral horizontal position to a locking-closed position in which the sash is held closed by the lowermost prong bearing against said stile, the said prong being held in tight engagement with the stile by the lowermost roller whose resilient material is distortedby pressure against said stile during achievement of said locking-closed position.

2. A device as defined in claim 1, and including a pair of projections adjacent the vertical edge of said plate remote from said slidable sash, said projections being arranged to bear against opposite sides of said arm at a point intermediate its ends and hold said arm in said neutral position.

3. A device as defined in claim 1, and including a plate rigidly secured to the face of said stile at a point just below the point of contact of said lowermost prong with a said stile when in the locking-closed position, whereby any attempt made to open the closed window from without will be thwarted by jamming of said second plate against said lowermost prong.
