to improve penetration into the pipe as can be best seen in the assembly view of fig3 these tapered edges when the blank is finally folded provide a relatively sharp penetration radius which coacts with the inner radius of the u bolt to provide the necessary bead in the pipe the next step as shown best in fig1 and 12 involves forming up the outer edges of the flange portions 24 and 25 to provide the necessary half box configuration for the bolt housing note the upturned edges 30 31 32 and 33 the first 90 u00b0 bend of the entire blank is shown in the subsequent step depicted in fig1 here the blank is turned upwardly along the edge of the triangular reinforcing rib 21 as shown to the left of section line 12 12 in fig1 to form a 90 u00b0 bend this is followed by the second 90 u00b0 bend shown in fig1 wherein the blank is bent over the full 180 u00b0 so that the two halves are in face to face contact providing the basic shape of the finished saddle assembly note that the upturned portions 30 and 31 will mate as shown best in the assembly view of fig4 and also the portions 32 and 33 will be in full line contact the central web portion of the saddle shown at w will also be in face to face contact and joined with the tapered portions 29 as shown in fig3 the edges of radii 27 and 28 forming.
