ATTORNEY.
Patented Mar. 9, 1948 STATES PATENT OFFICE 5 Claims.
Due to many causes, the use of metal window frames and sash is increasing and such window frames and sash can be and are manufactured for use with any type of building, including wood, concrete and brick.
The window sashes are constructed from preformed members which may be of any suitable metal, but which are preferably extruded from aluminum. Aluminum lends itself very readily to use in connection with metal window sash and frames because it can be extruded through dies so as to be absolutely uniform in shape and size. Such extruded aluminum frames also have a fine finish and produce an ornamental effect.
In the construction of window frames and sashes, it is necessary to interconnect various pieces that form the same and which are arranged in right angular relation. Such joints have heretofore been effected by welding. Aluminum does not lend itself very well to Welding operations and such a method of interconnecting the members has been found to be unsatisfactory and quite expensive.
It is an object of this invention to produce a joint that can be quickly made without the use of welding apparatus and which is very substantial and rigid.
Another object of the invention is to produce a joint for the purpose indicated that can be produced more quickly than a welded joint and which has many advantages over the latter.
The above and any other objects that may become apparent as this description proceeds are attained by means of a construction and an arrangement of parts that will now be described in detail, and for this purpose reference will be had to the accompanying drawing in which the invention has been illustrated in its preferred form, and in which:
Figure 1 is a top plan view of a window sash joint at the intersection of frame members A, B and 0, shown partly in side elevation and partly in section taken on line i-i, Figure 2;
Figure 2 is a section taken on line 22, Fig ure 1;
Figure 3 is a transverse section of frame member B taken on lines 3-3, Figures 1 and 2;
Figure 4 is a transverse section of frame member taken on lines 4-4, Figures 1 and 2;
Figure 5 is a View partially in section and partially in elevation looking through plane 5-5, Figure 1;
Figure 6 is a perspective view of the interconnecting member employed in making the joint;
Figure 7 is a diagram showing, in a general way, the relationship of the several frame members;
Figure 8 is a front elevational view of the joint shown in Figure 1;
Figure 9 is a side elevational view looking to the left in Figure 8; and
Figure 10 is an end elevation in Figure 8.
In the drawing reference numeral 10 desi nates a member which has also been indicated by the letter A and which is provided with a horizontal flange I I that terminates in a vertical portion I 2 that is connected with the base l3 by means of a web 5 shown most clearly in Figure 5. Extending upwardly from the bottom frame member i5 of the window frame is a preformed aluminum frame member [6 that has also been designated by the letter B. Frame member" C extends downwardly from the top frame member l8 and is interconnected with frame member B in the manner shown in Figures 1 and 2 to which reference will presently be made.
A reference to Figure 3 will show that frame member 16 or B has a wide base I? from one side of which webs l8 extend upwardly in spaced relation and are connected at their upper ends by the top portion I9 which, in the embodiment shown; has a rib 20 extending lengthwise thereof. Web. id of'member I8 is provided with a rectangular opening 2| of a Width equal to the distance between the outer surfaces of webs i8. Flange I7 is cut back to the point indicated by reference numeral 22 and top portion 19 is cut back to the line designated by reference numeral 23. The distance to which the top i9 and'fiange l? are cut back are such that webs it may project a short distance through opening 2| and have sufficient length topermit the ends tobe bent outwardly in the manner shown in Figure 1, and designated by reference numeral 24. In bendingthe ends 24 outwardly the end surfaces 22 and 23 are held in close contact with the abutting edges of member I0 and in this manner members A and B become interconnected, Mem ber C, which has also been designated by reference numeral Zda and which has spaced webs 25, has its base 25 cut back to line 21 and its top portion 28 cut back to line 29, leaving sufiicient lengths of webs 25 to extend into the space be tween webs It in the manner and to the extent shown in Figure 1. Before the extendin webs 25 are inserted between webs I8 a connecting member 30 is inserted in the opening between webs 25. The connecting member has been shown in somewhat greater detail in Figure 6, from which looking upwardly 3 it has a rectangular cross thicknesses but the same width. That part of the connector above line 3| in Figure 6 is of a size to fit the opening between webs 25 and is inserted into frame member I6 until the ends of webs 25 abut against the shoulder indicated by reference numeral 3| in Figures 1 and 6. The lower end or that part of the connector below line 3| in Figure 6 has a size and shape to lit the opening between webs I8 in the manner shown in Figure 3. Before the webs 25 of member 2411 are inserted into the opening between webs l8 they are subjected to a pressure forcing a portion of each web inwardly into the transverse notch 32 of the connector. These inwardly pressed portions have been designated by reference numeral 33 in Figures 1 and 5. The connector is now securely attached to frame member I! and cannot move longitudinally thereof. After the connection has been made by inserting an end of the connector into the opening. between webs iii, the parts are urged together with sufiicient force to effect a close contact between the abutting surfaces, after which webs I8 are subjected to pressure forcing them inwardly into the transverse grooves 32a. Such indented portions have been designated by reference numeral 33a in Figures 1 and 5. The parts are now rigidly and firmly interconnected and this interconnection has been eilected without the use of welding apparatus,
Instead of having notches 32, ing the webs 25 and I8 in the manner shown,
it will be seen that section of different 32a and indentthe 'frame members may be connected with the connector 30 by means of rivets passing through suitable holes in the webs. Any mechanical equivalent means can be substituted for the one shown and described above.
A joint like the one described can be manufactured and assembled with less labor than if it were interconnected by welding, and in addition to this the joint has many points of superiority, being neater in appearance and as rigid as a welded joint. In welding aluminum, as has been mentioned above, dimculties are often experienced and unless utmost care is taken, a joint that appears to be perfect may be found to be defective with the result that window frames and sash that have been manufactured at a big expense are rejected by the buyers. A joint constructed in the manner herein described is always reliable and is free from the irregularities of the surface that frequently are found in welded joints.
It will be obvious from an inspection of Figure 1 that when the plug 30 is in place, the ends of the web whose sides have been designated by numerals 25 will be in effect a solid member as far as resisting transverse pressure is concerned. 7
The Web and the plug therein are in effect the same as a solid web of equal length will be.
Having described the invention, what is claimed as new is:
1. The method of interconnecting three sash frame members, each of which has two parallel flanges connected by a web and in which at least two of the members have tubular webs of different thicknesses, the openings in which are of substantially rectangular cross section, shorter transverse inside dimension of the opening in the thicker web being the same as the shorter transverse outside dimension of the web of the other member, the distance between the outside surfaces of the flanges of all three members being the same; which consists in providing 1 that its web walls may the the web in the third member with an opening having a width equal to the outside shorter transverse dimension of the thicker tubular web, removing the flanges of the member having the thicker web to a point where the web walls may project through the opening in the web of the third member, with the ends of the cut back flanges in engagement with the edges of the flanges of the third member, bending the ends of the web walls that project through the opening, outwardly to overlap the sides of the opening, cutting back the flanges of the tubular web member with the thinner web to such a distance be telescoped into the opening in the web of the tubular web member with the thicker web, in which position the cut back flanges abut the edges of the flanges of said third member, positioning an elongated connecting member in the end of the smaller web, providing said connecting member with an end having the same shape and size as the opening in the larger web, inserting the smaller web and the connecting member into the opening in the larger web, and providing an interconnection between the ends of the connecting member and the webs with which they are in contact, whereby the interconnected frame members will be held against relative axial movement, and whereby a rigid joint is obtained.
