cross-member, forming a corner of the sash, and I imparting rigidity by impinging or embossing a portion of the structure or by mechanical means and covering the upper orifice in the perpendicular rail. Y 1

Another object is to provide a satisfactory corner structure in window sash by interlocking the end of a rail and the end of a cross-member, taking advantage of the rigidity resulting from the form of the members, and the method of telescoping and positioning said members.

Another object is to provide mechanical as-' sembly thereby avoiding welding or brazing themembers.

Another object is to permit the surface finishing of the members before assembly.

Further objects and advantages of the inven-- tion 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 sash rail and cross-member joined, disclosing the ends of said members telescoped forming a corner of the sash;

Figure 2 is an exploded view of the structure shown in Figure 1.

Figure 3 is a perspective view of an assembled sash corner and particularly illustrating .the method of impinging and embossing the rail to give rigidity to the structure.

Figure 4 is a perspective view of the means used to cover the upper opening in the perpendicular rail.

Figure 5 is a vertical view, partly in section, showing the said cover in position.

members.

- Figure 12 is an exploded view of the structure shown in Figure 11.

Figure 13 is a perspective View disclosing the adaptation of a further structural form of the members.

Figure 14 is an exploded view of the structure shown in Figure 13.

The complete window frame and sash havenot been shown in the drawings. However, it should be obvious that any sash possesses a plurality of corners, usually four in number, and that my invention would apply to any of such corners and that the detailed description herein as to one corner, refers to all with the apparent variance required between a right hand and left hand application. The sash itself, preferably of the double hung type, as indicated in the drawings, is designed to operate within a frame with a fixed upper sash, but I do not confine myself to this particular adaptation of my invention.

Similar numerals refer to similar parts throughout the several views Referring to Figures 1 to 5 of the drawings, the sash corner structure has a formed crossmember I substantially rectangular in crosssection, preferably witha hollow center, one side wall of which has an inturned L-shaped elongation 2 and the adjoining side wall nearest said elongation, has an obtrusion 3, the outside surfaces of said obtrusion 3 and the inturned lip of the elongation 2 being substantially on the same plane, forming a recess 4 for putty retention and providing a support for the glass pane.

The sash corner also has a formed side'rail 5 preferably with three side walls to save material.

Similarly, the side walls of the cross-member l the other end, of a height substantially less than v the thickness of said side wall 8. Another side bers are determined by the size of the sash and the particular application desired.

In preparing the members for joining, aportion of an end of the cross-member l is removed at substantially right angles to its axis, leaving the side elongation 8, in which a channel I3 is made to accommodate the obtrusionS, and the slot I4;

and the grooves and 16 cut, at substantially right angles to the axis ofsaid member, of suificient width and depth tolaccommodate the 0btrusion II and the inturnedleg of-the elongation- 10, respectively. A slot I! is cut in the end f the.

inner: wall of therail 5 of-sufiicient width and depth to accommodate the stud I8 of the cover 34. This coverumember 34 is of sufficient size to cover the opening in the top of the rail 5, caused by its form which is channel. shapedin crosssection, adding a finished appearance and preventing the admission of foreign objects. It is held in position by the substantially T formed stud I8 on its bottom side, which also assists in the mechanical joinery. In practice, the substantially rectangular cover 34 and the stud I8 are extruded as an integral piece but they can be fastened together, as separate pieces, by other means, such as welding the upturned li on the cross bar of said stud [8 to the base of the cover 34. The corner joinery is accomplished by placing the prepared end of the cross-member! in contact with the end of the side-rail 5, insert the stud IS in position with the recess H and then sliding and telescoping th two members into position, the elongation 8, channel l3 and grooves l5- and 16 in the member I intimately embracing orbeing embraced by the channel 1, obtrusions 9 and H and'inturned lip of the leg l0, and the cover held in position by the contact of the stud l8 with the upper wall of th member I and the inner wall of the member 5 as shown in the crosssectional view of Figure 5. In order to give the immobility. of the membersresultingfrom their impingement, the obtrusion H is distorted, embossed, or other equivalents thereof, on both sides of its point of contact with the inturned lip of the elongation 2 as shown at l9 and 20, respectively, and the upturned lip of the leg 6 is distorted, embossed, or other equivalent thereof, at

member 1 shown in Figures 1, 2, 3 and 5, inclusive, except that the obtrusion 3 has been elimi-: nated. The side rail 23 is similarto the side rail 5 shown in Figures 1 to 5, inclusive, except that the obtrusions 9 and H have been eliminated.

Also, in preparing the ends of the member forjoining, the channel I3, slot 14 and groove 15 shown in Figure 2, have been eliminated in they cross-member 22. Movement of the members along the axis of the side rail is preve n te d by mechanical-means, preferably thescrew 24,1111

greater rigidity to the structure and supplement-v .4 serted in the hole 25 in the side rail and the hole 26 in the cover after the assembly of the members. Likewise, in the structural form shown in Figures 11 and 12, the obtrusion 3 shown in Figures 1, 2, 3 and 5, has been eliminated, as well as the groove l5 in the cross-member 21. In order to save material, in some instances it may be desirable to avoid the useoia closed structural form in the cross emember by leaving an opening between two of the sides as shown at 29'. Similarly, it is readily apparent that that portion of the lower side of the cross-member I shown in Figure 3 between the obstrusion 3 and the side with the elongated leg 2, can be eliminated without substantiallyafiecting the structural strength of the member and thereby secure a saving in material. also, the obtrusion ll, shown in Figures l, 2, 3 and 5, has been eliminated from the side rail -28, Figures 11 and 12. Movement of the members along the axis-of the side rail is prevented by distortion as shown at 2| in Figure 5.

In Figures 13 andl4, the structural form of the members is similar to that shown in Figures 1-1 and 12, with the addition of the channel 30 in the,

exterior surface of the elongatedside ofthe crossmember3l to accommodate and embrace the in:-vv turned leg 33 of the side rail 32, thereby increasing; the surface area impinging at the corner joint and also creating agreater locking action.

It is readily apparentthat a modified method; of embossing as shownin Figure 5, or mechanical, means, shown in FigurelO, to prevent movement: of themembers along the axis-of the side-rail can beadapted toany of the illustrations; The terms, corner joinery and cornerj ointf-are used herein synonymously.

While I have shown and described herein, for

illustrative purposes, a preferred and alternative embodiment of the invention and method of prac-v ticing it, it shouldbe understood that consider able variation in the details of construction may be employed andthe method varied, without departing from the spirit and scope of the invention, as set forth in the following claims.
