17 Claims.

This invention relates to an improvement in a fastening device for doors or windows of the casement type.

The preferred embodiment of the invention discloses a fastener which is automatically operated when a door or window is closed or opened. Whether or not the door or window is operated manually or by means of a suitable operating mechanism is immaterial provided some means, for holding said door or window in fully closed position, is utilized. The preferred type of operator is shown and describedin my Patent No. 1,539,549 and consists of a worm gear mechanism by which the door or window is held in closed position.

Since much difiiculty has been encountered in providing suitable operators and fasteners for casement doors or windows, the present invention is shown applied to such structure. The present type casement window, for example, is arranged with an operator usually mounted on the sill and a fastener located mid-way of one of the frame stiles. The fastener and operator are independent of each other in operation and location and, therefore, require two sets of finished hardware. Furthermore, since it is a universal requirement that a casement window be equipped with a screen, a considerable problem is involved in so locating the screen that it will not interfere with the manipulation of the operator or fastener. Many of the present casement window fastening devices are of such proportion, arrangement and location as to hinder installation or removal of a screen. Furthermore, since these fasteners are generally located mid-way of the vertical stile of the frame and engage only the adjacent open edge of the window, they generally do not draw the window into weather tight engagement with the frame at the top and bottom. It frequently occurs that dirt on the outside sill prevents complete engagement of the lower rail of the window with the corresponding rail of the frame and, therefore, a fastener adapted to draw in the central portion of a Window into contact with the frame, tends to bend the stile of the windowsomewh'at out of shape. Since most operators are attached to the bottom rail of a window, there is a tendency, resulting from whipping by wind, for the upper free corner of the window to be sprung outwardly a distance of one-half inch or more. The fastening devices now on the market, although presenting great improvement over the old type used on casement windows, still fall short of perfection since they are unable to draw the window into such contact with the frame as to fully prevent entry of the elements when the window is in closed position.

The present invention marks a considerable advance in a casement window and door fastening device as it provides a fastener that is fully 5 automatic in its operation and will not only hold the door or window in closed position, but will pull in the upper free corner of the window or door though it be warped and sprung outwardly and would not otherwise be brought into contact with the frame and this, therefore, constitutes the principal object of the invention.

Another object of the invention lies in the provision of a fastening device which, while autornatically locking the window in closed position, will not interfere with the installation or removal of a fly screen or storm sash that may be applied to the inside face of the frame.

A further object of the invention has in the provision of an automatically operated fastener 29 which will function even though the window is inadvertently slammed or otherwise mistreated.

Another and further object of the invention lies in the provision of a fastener which, when the window is in closed position, is entirely concealed from view.

Other and further objects of the invention will be more fully understood from a consideration of the following specification which is taken in conjunction with the acoompanying drawings which 30 form a part thereof, and in which Fig. 1 is a front elevation of a casement window to which one form of the invention is applied and in which is shown an operator of the type referred to in the above listed patent;

Referring to the drawings, the invention shown mounted in a casement window structure, generally indicated by the reference numeral ID. This structure includes a casement frame H and Window 52. The frame It comprises upper and lower horizontal rails l3 and stiles I4. The Window l2 comprises upper and lower horizontal rails 56 and ii and vertical stiles ES. The particular contour of the rails and stiles of the frame and sash herein shown is of no consideration other than that these elements must be of such form as to cooperate to provide sealing contact of one with the other. An automatic window erator it, of the worm gear type, operated by a crank it is found preferable for use in connection with applicants fastener since an operator of this type is locked against any movement except that produced through rotation of the crank.

The fastener for securing the window l2 in full and complete contact with the frame I l is mounted in the stile E4 of the frame and comprises a vertically reciprocable plate 22. The lower end of the plate is tapered and fitted with a roller 23 which projects beyond the lower extremities of plate. The upper end of the plate is formed with a sloped wall 25, in the upper end of which is located a further roller 26. The plate is formed with upper and lower longitudinally extending

slots

25 and 29. A pin 3e, projecting through the slot 29 has threaded engagement with the stile M. A suitable washer 3| is mounted beneath the head of the pin to prevent removal of the plate. The upper slot 28 receives a pin 33 which is likewise threaded into the stile E4. The head of this pin projects through a horizontal slot in a guide block 35. The block 35 has flanges Bl which lie adjacent to and act as a guideway for the upper end of the plate 22. The block 35 is mounted on the inwardly directed flange 38 of the stile M by means of screws 39. Turning the screws 39 causes the block 35 and the upper portion of the plate 22 to move inwardly or outwardly for the purpose of altering the horizontal position of the roller 25. Further description of this adjustable feature will be considered in connection with the operation of the fastener. A third roller it is mounted adjacent the lower end of the plate 22, being so located as to project beyond the inner vertical edge of the plate for the purpose of contacting with the flange 38 of the stile l4 when said plate is vertically reciprocated.

The structure above described constitutes'the moving element of the fastening mechanism. The m ans by which the plate is vertically reciprocated is attached to the free stile H3 of the window and is shown as a bracket 43. The bracket is formed with a lower horizontal flange 44 which is continued upwardly at any desired angle to form a cam face it. When the window [2 is moved inwardly toward the frame i i, the cam face 35 strikes the roller 23, causing said roller, and the plate 22 on which it is mounted, to move upwardly. The pitch of the cam surface 45 of the bracket determines the ratio of vertical movement of the plate 22 to the horizontal movement of the window i2. This may be more clearly understood by a comparison of Figures 3 and 4 of the drawings. It will be noted, since plate 22 must move in a direction perpendicular to the direction of travel of the window, that no fasten- 1 commercial use, is known to be capable of drawing the window into close abutment with the frame.

Adjacent the rail I6, and mounted on the stile iii of the window, is a strike plate 4?. This plate is secured in any suitable manner, as by screws $8, and includes a depending portion 49 having' two angularly disposed cam flanges 5B and 5!. The roller 26, mounted on and projecting beyond the upper extremity of the plate 22, is adapted to first engage the flange 59, moving upwardly and over onto the more steeply pitched flange 5|. The more gradual the slope of the flange 5B, the greater the inward travel of the upper corner of the sash toward the frame when the plate 22 is moved upwardly. When the upper corner of the window has moved almost into abutment with the frame, the roller 26 is moved upwardly onto the flange 5!, the pitch of which being steep diminishes the inward rate of travel of the window but increases the force with which the window is caused to abut the frame for the purpose of providing a weather tight seal between said window and said frame. The length of the portion 49, as well as that of the flanges 56 and 5|, is governed by the size of the window and the distance it is desired to have the roller 26 move the upper portion of the window inwardly to abut the frame.

The operation of the device above described, is as follows: The operating crank by which the window is moved from one position to another is manipulated to draw the window toward the frame. When the lowermost free edge of the window has approached to within approximately one-fourth inch of the frame M, the cam face d5 contacts with the roller 23 on the plate 22. As the crank is further turned to draw the lower portion of the window into abutment with the lower part of the frame, the cam face bears against roller 23, causing it to move upwardly along the cam face. Since the direction of travel of the cam is perpendicular tothat of the direction of travel of the plate 22, the roller M is provided to contact with the frame flange 38 for the purpose of decreasing friction. The 5 vertical travel of the plate 22 is limited to the length of the

slots

28 and 29 but it will be noted that this is at least twice the distance of inward travel of the lower edge of the window toward the frame. By reason of the fact that 0 the upper free corner of practically every casement window is unsupported, since the operator is usually mounted on the casement sill and engages the lower rail of the window, said upper portion is very frequently sprung somewhat out of alignment with the lower portion of the win dow. In fact this is found to be a usual rather than an'unusual condition. Figure 3 of the drawings, there-fore, illustrates this condition by showing the upper free corner of the window to be 0 sprung out of alignment with the lower free corner by approximately one-fourth inch. As the plate 22 is moved upwardly at a rate of speed twice that of the inward travel of the window toward the frame, the roller 2% is caused 5 to abut and travel upwardly along the cam face 5% and since the roller 26 is constrained to vertical movement, the upper free portion of the window must move inwardly approximately a distance twice that of the lower portion of the 7 window. When the upper free portion of the window has very nearly approached the frame, the roller 2% leaves the cam face 56 and moves upwardly onto the face 5!. This cam face is of a pitch which, while diminishing the inward 7 rate of movement of this portion of the window, increases the force of the roller applied to cause the window to closely abut the frame. Since the inward travel of the upper free portion of the window is dependent upon the vertical movement of plate 22, and the vertical movement of plate 22 is dependent on the inward movement of the lower free portion of the window, it is evident that if a window operating mechanism is of sufficient ruggedness to cause the lower free portion of the window to sealingly abut the frame, the fastening mechanism will be operated to cause the upper free portion of the window to abut the frame in a like manner. As brought out above, the operating mechanism must be provided with locking means to retain it in adjusted position with the lower portion of the window abutting the frame.

The guide block 35, which is laterally adjustable by means of screw 39 subsequently to the release of locking pin 33, is adapted to move the upper end of the plate 22 and roller 25 inwardly or outwardly for the purpose of drawing the window into closed abutment with the frame or loosening the window should it improperly abut at this point. This feature may be more clearly understood by an illustration in connection with Figure 3 of the drawings. In this figure it is assumed that the upper portion of the window has been sprung outwardly. It is apparent that when the window operator moves to draw the window into abutment with the frame the upper portion of said window will fail to abut the upper portion of the frame by a space equal to the extent of misalignment. Adjustment is made as follows, the window is opened, pin 33 rotated to release the guide block 35 and the window again closed. The adjusting screws may now be rotated to move the guide block inwardly which movement will draw the plate 22 and roller 25 inwardly causing the adjacent portion of the window to be drawn into abutment with the frame. The window is then opened and the pin 33 rotated to lock the guide block in its new position. Unless some accident occurs to the window such as would make it impossible for any operator or fastening device to function, the present fastener will continually serve to draw the upper portion of the window into abutment with the frame simultaneously with that of the lower portion of the window.

Although applicant has shown and described only one modification of his invention as applied to the fastening of a casement window, it is contemplated that the invention may be utilized for the fastening of other closures and also any modifications or adaptations of the present structure which may be made in so far as they do not depart from the spirit and scope of the invention as defined in the hereunto annexed claims.
