8 Claims.
In the manufacture of aluminum sash and doors it is diilicult to produce a satisfactory corner joint because of the nature of the metal, and this is particularly true where some of the rail members are made of sheet aluminum. The use of screws or rivets will render such a joint rigid, but their appearance is objectipnable and they have a tendency to draw in the surrounding metal unevenly, with consequent irregularities amng the une of the joint.
In my earlier filed application, Serial No.
i 51,046, a welded corner joint is shown which will overcome these objections, and satisfactory joints can be produced in accordance with the disclosure in that application except whenan electro-chemical or so-called alumelite or anodic nish is used. When either of these finishes is used, discoloration will take place at the weld due to the difference in the metal in the welding rod and the heat which must necessarily be applied to the joint to produce the weld.
When a mechanical joint, on the other hand, is made with other metals in connection with aluminum sash and door constructions, an electrolytic action will take place between the different metals and cause corrosion to both the aluminum members and the foreign metal parts.
A somewhat similar problem has heretofore been experienced in making up sheet metal sash with a chrome plate nish. In the past the methsod of making a solid corner has ordinarily consisted of mitering the sash rails, placing a sheet metal reinforcement. in the mitered ends and soldering the assembly. In soldering such joints the solder does not always seal the joints perfectly but leaves pores. In the process of chrome plating gases formed in the hollow rail sections cause a so-called spitting effect through these pores or open joints, preventing an even deposit of chromium around the joint area, which from an appearance standpoint is quite objectionable. The locked or mechanical corner construction which forms the subject matter of the present invention overcomes this objection as the rails can be plated individually and assembled and locked after the plating.
The object of this invention is to provide means for obtaining a rigid joint between aluminum rail members without the use of screws, rivets or other visible connecting devices, and also without the use of attaching parts made from metals other than aluminum.
Other more specific objects and advantages of the invention will be apparent to those skilled in the art upon a full understanding of the new corner joint construction.
A few embodiments of the invention are presented herein for the purpose of exemplication, but it will of course be appreciated that the invention is susceptible of being embodied in other structurally modied forms coming equally within the scope of the appended claims.

The sash which is illustrated in Figs. l to 4 inclusive is made up of an extruded aluminum bottom rail I0, a sheet aluminum side rail II and a sheet aluminum top rail I2. The lower end I3 of the side rail II is cut at right angles to fit against the upper edge I4 of the bottom rail I0 flush with the end I5 of the latter. A glazing groove I6 is formed in all of the rails along their inner edges, and additional grooves are formed in the side and bottom rails opposite the groove I6, a -groove I 'l being provided in the upper edge of the r,side rail II for the reception of a rubber bearing strip I8 and a groove I9 being provided in the lower-edge of the bottom rail I0 for the reception of a rubber sealing strip 20.
The side rail I I is hollow between the bottom 2I of the groove I6 and the bottom 22 of the groove I1, and the space between the same and the side walls 23 of the rail is rectangular in cross section except for narrow openings between the side walls and the sides of the groove I6. A closely nti-.ing solid block 24 of aluminum, provided with side ilanges 26, is pressed up into this space at the lower end of the side rail II, to a point where the lower end 26 of the block projects below the lower end of the side rail for a distance equal to the depth of the groove I6 in the upper edge of the bottom rail I0. The pro- -jecting end 26 of the block is reduced in width to t snugly between the sides of the groove I6 in the bottom rail. The block 24 is provided with two or more circular apertures 21 which extend through the block from one face to the other and open against the bottoms oi the grooves I6 and I1. 'I'he metal of the bottoms 2| and 22 in opposition to the apertures 21 is stamped into the ends of the apertures in the shape of tightly ttin'z tubular formations 28. These formations lock the block 24 securely within the lower end of the side rail. 1
The bottom 29 of the groove I6 in the bottom rail, which is comparatively thick and substantial, is provided with an aperture 30 beneath the lower end of the block 24, and a screw 3l is positioned in the aperture 30. The screw 3| extends upwardly into a threaded hole in the lower end of the block 24 and clamps the side rail tightly down on the end of the bottom rail. The ein of the web 29 which constitutes the bottom of the groove I6 in the bottom rail is cut back from the end of the rail, as is also the end of a second underlying web 32 in the rail, whereby to provide a groove down the end of the bottom rail as an extension of the groove I1 in the outer edge of the side rail. The extreme end edges of the bottom rail are flanged inwardly at 33 to provide continuations of inturned flanges 34 at the sides of the groove I1 in the side rail. which flanges hold the rubber bearing strip I8 against displacement.
The space in the bottom rail I between the horizontally extending webs 29 and 32 provides a guideway 35 for a slidably mounted latching bolt 36 which projects from the end of the bottom rail through an opening 31 in the rubber bearing strip I8. The bolt is projected by a coil spring 38 which is located behind the same in the guideway. The spring 38 is held compressed against the rear end of the bolt by a pair of ears 39 which are struck into the guideway from the webs 29 and 32.
In the embodiment of the invention which is illustrated in Figs. to 7 inclusive an extruded aluminum bottom rail 40, similar to the bottom rail in.the iirst described embodiment, is connected with an extruded, as distinguished from sheet metal, side rail 4I. A coupling block 42 is positioned in the lower end of the side rail 4I and is held rigidly in place by means of lips 43 which are forced from the bottom 44 of the glazing groove in the side rail into correspondingly shaped pockets 45 in the opposed face of vthe block. Only two of the lips 43 are shown but more of them can be employed if desired. The lower projecting end 46 of the block 42 is disposed in the glazing groove of the bottom rail 40 and is engaged by a screw 41 which extends upwardly through the upper web 48 in the bottom rail.
In the embodiment which is shown in Figs. 9 to inclusive a corner joint of more permanent character is provided between an extruded botanical? tom rail 4l and an extruded side rail 46. In this embodiment the connection is established by an L-shaped metal stamping 6I, which is preferably made oi sheet steel. This stamping has a horizontally extending hollow leg 62 ot generally rectangular cross section which nts snugly within the open end oi the bottom rail between the upper and lower webs 62 and 64, and a vertically extending hollow leg 66 of U-shaped cross section which nts snugly within the lower end of the side rail between the bottom 66 of the glazing groove and two small ribs 1 on the inside of the side rail. The portions the legs 62 and 55 which engage with the portions 63 and 66, respectively, of the bottom and side rails are provided with rectangularapertures 66, and lips 65 from the rail portions 53 and 66 are struck into these apertures and upset into press-nt engagement with the same. The engagement of the lips 53 with the edges of the apertures furnishes a strong, rigid connection between the rail members.
In the embodiment which is illustrated in Figs. l1 to 14 inclusive, an extruded side rail 66 is detachably connected with an extruded top rail 6I by the use of blocks 62 and 62, which blocks are on the order of the previously described block shown in Fig. 5. The block 62 is held fast within the upper end of the side rail 6I by means of struck-in lips 64 in the bottom of the glazing groove in the side rail, and the block 62 is similarly secured within the adjoining end of tue top rail 6 I In this particular' embodiment, the meeting ends of the two rails are mitered, and a screw 65 is employed to draw the mitered ends tightly together. The screw passes downwardly through a hole 66 in a portion 61 of the block 62 which projects partially into the upper end of the side rail, and the lower threaded end of the screw engages within a threaded socket 6I which is located in the upper end oi' the block 62.
While the invention has been herein illustrated and described as used in connection with a sash, it will of course be appreciated that the same is equally applicable to doors, panels and other like structures.
