Application filed February 7, 1924. Serial No. 691,104.
The invention relates to closure-fastening bolts, such as are particularly applicable to casement windows, doors, and like structures.
The principal object of the invention is to provide a closure-fastening bolt which may be easily manipulated to effect a stable connection of the closure with both the lintel and sill of the associated closure frame.
Another important object is to provide such a bolt which is adapted to function in the dual capacity of a bolt and hinge in such articulated closures as double casement windows, folding doors, and like structures, wherein the connection of the closure with both the lintel and sill of the associated frame may be quite advantageously located in alignment with the articulated portion of the closure.
Another object is to provide such a bolt which is of a pleasing though inconspicuous appearance, and which is possessed of a simple yet durable construction susceptible of very economical production.
While the foregoing statements are indicative in a general way of the nature of the invention, other objects and advantages not specifically referred to in this disclosure will be obvious upon a full understanding'of the construction and operation of the both as set forth in the following description and accompanying drawings, wherein is presented a preferred embodiment of the invention. It will'be understood, however,
that such particular embodiment is chosen primarily for the purpose of exemplification, and is not intended to restrict in any way the spirit of the invention or to limit unnecessarily the scope of the appended claims.
In the draw1ngs:-
Fig. 1 is a fragmentary inside View of Fig. 6 is a vertical section on the line 6- of Fig. 5, and
Fig. 7 is an inside view of the upper portion of that form of the bolt illustrated in Figs. 5 and 6. l The closure-fastening bolt of the invention includes a. rod 10, a number of rod-journalling brackets 11 secured'to the associated closure 12, a manipulating handle 18' secured to an intermediate portion of the rod 10, two latching members 14 .and 15 se cured to the upper and lower ends respectively of the rod 10 with their bearing surfaces tangential to a curve described about the axis of the rod, and two striker- plates 16, and 17 secured to the lintel and sill respectively of the'a'ssociated frame 18 with their bearing surfaces in the line of thrust of the rod 10 when the latter is in a locked position;
The closure12, to which the closure-fastening bolt is applicable, maybe in any one of many different forms, but in the present disclosureis exemplified in the form of a double casement window having two sash portions 19 and 20 which are pivotally connected at their abutting margins to each other and at their separated margins with two members slidably mounted in thelintel 21 and sill 22 of the frame 18. Such a window is opened or closed by moving the from or into the plane of the frame. The closure-fastening bolt, when applied to such a window, may function in the dual capacity of a bolt and hinge by employment of the rod 10 as the pivot between the sash portions 19 and 20 and employment of the brackets 11 as the lapped hinge butts for the pivot between the sash portions.
The rod 10 which is preferably of circular cross-section throughout its length, extends vertically along the junction of the sash portions 19 and 20 to points adjacent the lintel 20 and sill 22 of the frame; The brackets 11 are arranged'in pairs like hinge leaves and are secured at opposite sides of the rod 10 to the margins of the sash portions 19 and 20. The handle 13 is secured to the rod 10 at about the middle of the same, and is arranged parallel to the plane of the frame whenthe rod is in the locked position shown in Fig. 2 and perpendicular to the plane of the frame when the rod is in the unlocked position shown in Fig. 3. The
hinged margins of the sash portions away latching members14 and15 are secured to arecurved, as shown in Fig. 2, to provide curved bearing surfaces 26 .on their edges for coaction with the. bearing surfaces 24 of the latching members 14 and 15.
The disposition of the striker-plates 16' and 17 on the lintel 21 and sill 22 of the frame is such that, whenthe bolt is in the unlocked position and the sashporti-ons 19 and are being moved by the handle 13 away. from or into the plane of the window frame, the striker-plates will not interfere with the latching members 14 and15, and
that, when the sash portions are in their closed position and the bolt is turned by the handle into the locked position, the bearing surfaces 24 of the latching members will ride about the curved bearing surfaces 26 of the striker-plates and. will, by such coaction, draw the sashportions into. a tightly closed position as the bearing surfaces24 of the latching members assume a position in parallelism with the plane of the win- ,dow. The bearing surfaces 26 of the strikerplates curve inwardly at27 away from the bear ng surfaces 24 of the latching members 1n order to avoid engagement between the bearing surfaces 24 and 26at points other than those tangential to curves described a about the axis of the rod with radii corresponding to the offset of the bearing sur-. faces 24. Such supplemental curvature of thebearing surfaces overcomes any tendency whlch the rod 10 might otherwise have to shift into a partially unlocked position under continued jarring of the sash portions.
The disposition of the bearing surfaces 24 tangentlal to a curve described about the axis of the rod 10 results in a stable engagement of the latching members with the striker-plates, since any attempt to move the sashes from their closed position acts through the pivotal axis of the rod against the bearing surfaces 24 in a direction normal to the same at their point of engagement with the bearing surfaces 26 of the strikerplates in the line of thrust of the rod. 7
In Figs. 5, 6 and 7 is shown a slightly modified. form of the invention wherein the upper latching member 14 is provided with a horizontal flange 28 which is upwardly tipped at its forward end. The flange 28- is intended to ride onto. the flange 25 of the upper striker-plate 16 as the sash portions assume their closed position, and serves to support the sash portionsmedially when the same are in either their closed or locked position. This arrangement is particularly of advantagein wooden sash structures wherein warping or settling might occur.
While the bolt of the'inventfion is illustrated in the present-disclosure in association with a double casement window and in such association functions in the dual capacciated that theinvention is applicable to all forms of closures.
