Kessler, Bristol, Ind., assignor to Victor M. Langsett, Chicago, 111., as trustee Application November 7', 1946, Serial No. 708,286
3 Claims.
This invention relates to improvements in means and methods of attaching and anchoring the muntins in a window sash to the cross and side rails of the sash, aswell as the muntins themselves where they cross one another.
The particular form and joinery of the cross and side rails of the sash are set forth in my co-pending application Serial No. 700,693 filed October 2, 1946.
The muntins are preferably made of formed metal or metal alloy sections by extrusion but it is readily apparent that any formed material, plastics for example, may be used.
An object of my invention is to provide means for joining the muntins in a window sash to the rails, and to themselves, where they cross, by adapting the contacting ends of the muntins to the adjacent contours of the rails and cross muntin, thereby interlockin the members, and imparting further rigidity to the structure, by mutilating or embossing an obtrusion on the rail or cross muntin adjacent to the muntin end.
Another object is to provide a mechanical assembly thereby avoiding welding or brazing the members.
Another object is to permit the surface finishing of the muntins before assembly.
Another object is to provide an efficient and cost reducing method of installing the muntins in the sash after the rails have been assembled.
A further object is to provide means for fastening the muntin ends without affecting the structural strength of the sash rails and cross muntins.
Further objects and advantages of the invention will be apparent from the following specification and the accompanying drawings, wherein a preferred embodiment of the invention has been shown and described.
In the drawings;
Figure 1 is a perspective view of a cross sash rail and vertical muntin joined.
Figure 2 is a perspective view of the form and end treatment of the muntin.
Figure 3 is a side View of the muntin end shown in Figure 1.
Figure 4 is a side view of the cross sash rail and muntin in position, showing the method of mutilatin and distorting an obtrusion on the cross rail, thereby holding the muntin in place.
Figure 5 is a side view of the muntin end joinery taken at right angles to the axis of the cross rail, which is shown in cross-section.
Figure 6 is similar to Figure 5, showing the mutilating and distorting of the obtrusion on the cross rail. 1
Figure 7 is a perspective view of a cross muntin and the upper vertical muntin joined.
Figure 8 is a perspective view of a side sash rail and muntin end joined, the muntin form varying from that shown in Figure 1.
Figure 9 is a side view of the structure shown in Figure 8, more clearly showing the mutilation and distortion of the obtrusion on the side rail.
Figure 10 is a top view of the muntin showin the end treatment.
Figure 11 is a top view taken at right angles to the axis of the side rail, which is shown in cross-section, showing the mechanical joinery.
Figure 12 is similar to Figure 11, more clearly showing the distortion of the obtrusion on the side rail adjacent to the muntin end.
The complete window sash has not been shown in the drawings, but it should be obvious that any sash has a plurality of side rails and cross rails, usually two side rails and an upper and lower cross rail, the muntins which may be vertical or horizontal, or both, or, in some instances, on the diagonal.
Similar numerals refer to throughout the several views.
Referring to Figures 1 to 6 inclusive, of the drawings, the sash cross rail I, substantially rectangular in cross-section, preferably with a hollow center, has one side wall with an inturned L-shaped elongation 2 and the obtrusion 3 on the adjoining side wall nearest said elongation, the outside surfaces of said obtrusion 3 and the insimilar partsturned lip of the elongation 2 bein substantially on the same plane, forming the recess 4.
The vertical muntin to be attached to said rail I, an end portion of which is shown at 5, has a base 6, the stem 1 and the head 8 with both ends inturned, forming a block letter T in crosssection.
The end surface of said muntin is formed at right angles to the axis of the muntin, so as to rest firmly upon the exterior face of the cross rail I, to which it is locked. To form the jointure means, a channel 9 is formed in the head and inturned legs of 8 and the stem 1, at right angles to the axis of said muntin, at a height, and to a depth and width to accommodate and intimately embrace the inturned lip of the elongated leg 2 of the rail I and another channel I 0 is formed in the inturned legs of the head 8 and the stem I, to a Width and depth to accommodate and intimately embrace the obtrusion 3 on the rail I. To assemble the muntin and rail, a portion of the obtrusion 3 of the rail I is removed a short distance from the final position of the muntin, as at figures.
' at substantially right angles thereto. of these heads, 22, 22 are inturned, forming?! muntin is prevented by mutilating and distorting the obtrusion 3 on both sides of its point of contact with the stem 1 of the muntin 5, as at l2, l2, thereby firmly fixing it in position and adding rigidity to the structure.
Referring now to Fig. 1 for example, it-should be noted that the terminal edges of the legs or flanges on the sash rail and also on the muntinterminate in a common plane when assembled as shown in Fig. 1. Thus these edges provide planar surfaces against which the inner surfaces of flat planes of glass may be abutted, after which putty or other glazing compositions may then be applied tothe. juncture of the opposite surfaces of the glass and the adjoining surfaces of the muntin and sash rail, as is customary. The sheared notch ll and the swaged or upset portion l2 of the ridge 3 will of course be concealed by the glazing composition- It is obvious that similar joinery may be-used in attaching the muntins to other rails in the sash.-
,Where both horizontal and vertical muntins e used n the .sa h,,provis ion m st be made f r the cross joints. This form of joinery is shown in Figure 7. In the interest of structural strength, the horizontal muntin I3 is one continuous length. This muntin I 3 is of similar form to the vertical muntin 5, with the addition of the obtrusions I4, M, on both sides of the stem I, thereby forming .a recess and arrangement similar to that Of the inturned leg 2 and obtrusion 3 of the rail I. The end of the vertical muntin section is formed and the assembly of the cross joint is completed as described above, further movement of the vertical muntin section being prevented by the mutilation of the obtrusion M on both sides of the stem], as shown at I5, l5.
It is apparent from the foregoin description, that the muntins maybe surface finished and installed in the sash, frame after the rails have been assembled, thereby facilitating the manufacturing process. Furthermore, the interlocking of the prepared muntin ends with the contours of the rails and cross-muntins, and mechanical immobilization, makes welding or brazing unnecessary, thereby substantially reducing the cost of the assembly. 7
Where diagonalmuntins are u d in a sash, it is obvious that similar means and methods described above may be used, the muntin ends, channels 9 and 10 being formed on a bias to conform to the angles desired and the particular sashdesign.
In Figures 8 to 12, inclusive, a form of muntin is shown varying from that disclosed in previous This form is adaptable where no cross muntin is used. One side of the side rail I6, has an elongated inturned leg 61, and the side adjacent thereto, an obtrusion l8, forming the recess I9, the exterior surfaces of the inturned lip of the leg I! and the obtrusion I8 being substantially in the same plane. The muntin has a stem 2| with the heads 22 and 22' at each end thereof and The ends glazing support and recess for putty retention. The end surface of said muntin is formed at right angles to the axis of the muntin, so as to rest firmly upon the exterior face of the side rail It, to which it is locked. To form the jointure means, a channel 23 is formed in the head and inturned legs, 22, and the stem 21, transverse to the axis of said muntin, at a height and to a. depth and width to accommodate and intimately embrace the inturned lipof the leg I? of the rail [6 and another channel 24- is formed in the inturned legs of the head 22 and the stem 2 I, to a depth and width to accommodate and intimately embrace the obtrusion I8 of the rail Hi. The muntin and rail are then interlocked as hereinbefore described, the channels 23 and 24 conforming to and intimately embracin the inturned leg I! and obtrusion i8 respectively, and mechanically held in position by the mutilation or distortion of the obtrusion l8 on both sides of the muntin as indicated at 25, 25,
While I have shown and described herein, for illustrative pu poses, a preferred and alternative embodiment of the invention and methods of practicing it, it should be understood that bone siderable variation in the details of construction may be employed and the method varied, without departing from .the spirit and scope of the invention, as set forth in the following claims.
