Figure 3 is aperspective view of the end of The

notches

15 and 16, on each end of the 50 abeam such as shown in Fig. 2; and beam merge with the grooves at that end. Figure 4 is a slightly modified construction The result is that at each end of the beam a in which grooves are formed on one side only tenon 17 is formed. The

grooves

12 and 12 of the beams. are made somewhat wider than the tenons 17 It will be understood that beams of the thus forming ledges 17 at the bottom of 55 type herein disclosed are used for building the grooves. The pair of

grooves

12, 12 at structures of octagonal shape or other shapes, each end of the beams are not arranged d1? rectly opposite to each other but are offset laterally. The

notches

16 and 17 therefore extend diagonally of the length of the beam. This offset arrangement of the grooves and diagonal arrangement of the notches is, of

course, necessary as the beams are intended to be laid at an obtuse angle to each other in forming an octagonal or other bulldlng hav ing obtuse angles at the corners.

Figure 4 shows an arrangement in which the beams 20' are provided with grooves 22 on one vertical face only, the other face being left straight. This'arrangement, however, is similar to that shown in the other forms of the. device in that the grooves '22 are provided with inclined side walls 22*? which flare outwardly from the bottom .Of the groovs to the surface of the vertical sides. The rest of the joint arrangement, illustrated in Figure 4;, it is not necessary to'describe as this forms no part of the present appli- 'isclaimed as new and desiredto be secured by Letters Patent is:

1. A rectangular building beam having on one vertical side a pair of spaced vertical grooves therein and also having upper and lower notches on each edge merging with said grooves to form tenons in the beam, each of.

said grooves increasing in width from the bottom thereof outwardly to the surface of the vertical side of the beam.

2. A rectangular'building beam having on one vertical side a pair of vertical grooves, spaced apart, and also having upper and lower 7 notches on each edge merging with said grooves toform tenons in the beam, the side walls of each of saidgr-ooves flaring outwardly from the bottom of the grooveto the surface of the vertical side of the beam,

A rectangular building beam having on each vertical side thereof a vertical groove,

a notch on each edge of the beam merg ng with said grooves, whereby atenon is formed in the beam, the side walls of each of said grooves flaring outwardly from the bottoms .of the groovesto the surfaceof the vertical side of the beam. r

rectangular building beam'hav ng on one vertical side a pair of vertical grooves spaced apart and also having notches on the upper and lower edge thereof merging with said grooves to form tenons, each of said grooves at its outer portion being wider than it is at the bottom thereof.

5. A rectangular building beam having a pair of vertical grooves one on each vertical side thereof, a notch on each edge of said beam extending between said grooves, whereby a tenon is formed in the beam, the bottom of'each groove being wider than the length of the tenon, and the sidewalls of each groove flaring outwardly from the bottom thereof to the surface of the vertical side ofthe beam.

In testimony whereof I hereunto affix my signature.
