JOINT STRUCTURE FOR DOORS AND SASHES Filed July 20, 1950 7 M /9 A48 Q /2 2/ 5 A r- INVENTOR. A, J K/efier BY 14/3 fl-lhrneq,
Patented Mar. 9, 1954 UNITED STATES PATENT OFFICE 2,671,539 .JOINT STRUCTSUEE FOR DOORS AND SHES "lclaim. *1 My present invention consists in ,a .new and improved welded union between the extremities of the rails of'adoor'orsash'withthe edges of the stiles of such structureto which the railszare to be permanentlysecured.
The :object which .I have in view is the .production of a rigid welded union between the rails and the stiles which may be inexpensively and conveniently produced,.andhaving a welded area at the union which .is subsequently ground up and polished to'harm'onize with the finish of the adjacent areas of the elements which are-welded together.
Where the metals used infabricating the door or sash are of the relatively low melting point generally used in modern practice for such purposes, as, for instance, aluminum, the welding, preferably with added metal, of the stil and rail, frequently causes the adjacent metal to flow, leaving an unsightly sunken and marred area adjacent the weld which cannot be eliminated or concealed. This is especially true when the stile and rail are in the form of hollow die-cast manufacture, as is usually the case in modern practice in metal doors and sashes. This exposure to heat tends to collapse the hollow elements.
To remedy this fault I have provided a novel and much improved structure, involving an outwardly projecting flange or flanges preferably on the edge of the stile which, as the elements are assembled for the welding operation, engage and interfit with slots formed preferably in the end of the rail, with the vertical edge of the first element, preferably the stile, fitting snugly against the extremity of the rail. The said flange is stepped inwardly from the adjacent face of the stile, and the slot in the end of the rail is likewise stepped in front of the side face of the rail so that when the elements are fitted together the side faces of the stile and rail are located in the same plane.
Preferably I provide a second flange on the vertical edge of the first named element, the stile, spaced from the first named flange and also from the other adjacent side face of the stile, which second flange fits in a second slot in the end of the rail so positioned that the adjacent faces of the stile and rail ar in the same plane.
The joint thus formed is welded at both sides, preferably with added metal of the same character as that of which the stile and rail are composed, the metal fusing with the metal of the parts to be united and flowing inwardly between the interfitting portions of th stile and rail, thus forming an integral joint between the same.
.The exterior areas of the welded union are ground .andpolished until thesame are-reproduced in conformity .in appearance with theportions of the stile and rail surrounding th weld. Thus a permanent union of the parts is produced giving .hitherto impossible strength and finished appearance.
Other objects will appear from the following description.
In the accompanying drawings, 'which'areintendedto indicate an embodiment loftheprinciplesof my present invention,
Fig. 'l is a view in'perspectiveof vthe 'space'd vertical edge of the stile'and of'th'e end portion of the bottom'rail'whichis 'tointerfit withxth'e "stile and" to bewel'ded thereto.
Fig. 2 is a cross-sectional view of the stile and rail assembled with the flanges on the vertical edge of the stile fitting into the corresponding slots in the end of the rail and an added metal weld accomplished;
Fig. 3 is a like View after the welded portions of the stile and rail have been ground and polished to restore the finished surfaces of the welded areas.
Referring to the drawings, the stile indicated at 10 and the rail indicated at H are, as is now the practice in the art, hollow die-castings, the stile having a vertical edge wall l2 and vertical side faces l3 and [4, while the rail is shown having the end l5 which, when the parts are assembled for welding, fits against the edge wall l2 of the stile. The rail also is provided with vertical side faces 16 and i1 and at its horizontal edge is provided adjacent its side with side walls l8 which enclose and form the top and bottom edges of the rail when the door is assembled. The stile and rail are of the same Width between their vertical side walls so that when the parts are assembled, as shown in Fig. 2, the wall 13 of the stile and the wall N5 of the rail lie in the same plane as do, likewise, the walls l4 and I1.
One of the two elements, preferably the stile, is provided with a flange l9 extending from its vertical edge l2, which flange is arranged to fit into the corresponding slot 20 in the ends of the walls 18 of the rail H. The flange and slot are positioned inwardly from the walls l3 and IE of the element so that when the elements are fitted together for welding, the edges of the walls l3 and It and It and I1, respectively, mate together in the same planes.
Preferably a second flange 2| extends from the edge 12 of the stile, and the wall 18 of the rail is provided with corresponding slots 22 in the walls "3 to receive said second flange 2|.
The second flange 2| and the slots 22 are spaced from the first mentioned flange l9 and are spaced inwardly from the corresponding side wall M of the stile and side Wall I! of the rail, so that when the elements are assembled as shown in Fig. 2, the wall I 4 of the stile mates with the wall I! of the rail in the same plane.
When the parts are assembled, as shown in Fig. 2, the parts are welded by heat together with added metal from both sides, the added metal being illustrated at 23. The added metal flows with relative ease and the interengaging surfaces of the parts are softened by the heat of the welding operation as indicated at a on the drawings, thus fusing together and forming when cooled a permanent and strong union between the parts which cannot be separated without ruining the structure. Furthermore, the welded areas, when ground and polished, are no longer discernible.
The flanges may be provided on the end of the rail, and the grooves, with which the flanges are interfitted, may be formed in the vertical edge of the stile, but the arrangement set forth supra is considered preferable.
I claim:
A welded joint between the stile and rail members of a door or window sash comprising a stile member and a rail member each being a hollow box member with front and back Walls spaced by side walls, the front walls of said stile member and said rail member being congruent with their back walls and the corresponding front and back walls of said stile member and rail member lying in the same corresponding parallel planes, the end of one member butting against and at right angles to the side wall of the other member. a. pair of flanges independent of and projecting outwardly from the side wall 01 said other member, each flange extending for at least the full width of said one member and lying parallel with but stepped inwardly of the front and back walls for the thickness of the corresponding front and back walls of said one member, aligned parallel slots in the side walls of said one member snugly receiving said parallel flanges to support the edges of the front and back walls of said one member in abutting relation with the edges of the front and back walls of said other member, the adjacent edges along the continuous lines of contact of said abutting walls and flanges being secured together to produce a reinforced and interlocked joint with a continuous surface from the stile member to the rail member.
