notch 79 formed therein as best seen in fig5 b the notch 79 is configured to partially receive nails not shown therein this can best be seen in fig6 b the second surface 77 is angled to allow the driver blade 54 fig4 to strike the second surface 77 thereby moving the pusher assembly 60 out of the way of the driver blade 54 during a stroke of the driver blade 54 with reference to fig5 b the pusher assembly 60 further includes a biasing member 80 such as for example a spring the biasing member 80 is mounted between the runner 66 and the arm 78 to bias the pusher 74 such that the bayonet portion 72 cannot be accidentally disengaged from the hole 76 moreover the biasing member 80 biases the pusher 74 to be in alignment with the nails not shown loaded within the magazine 24 fig1 turning to fig6 a as noted above the pusher assembly 60 slides within the magazine 24 fig1 to drive the nails 53 into the channel 52 of the nosepiece assembly 22 however when all the nails 53 have been expended from the magazine 24 the pusher 74 enters the channel 52 if nails have been loaded into the magazine 24 while the pusher 74 of the pusher assembly 60 is located within the nosepiece 28 the pusher 74 would force the nails back until such time as the pusher 74 is no longer within the nosepiece 28 and the pusher 74 may move out of alignment with the loaded nails accordingly the channel 52 includes a pusher pocket 82 formed therein and sized to receive the pusher 74 this allows the pusher 74.
