An apparatus for connecting bars includes a clip string, a barrel having a clip receiving cavity, with a terminal clip of the clip string received in the clip receiving cavity. A drive is received in the barrel and extends proximally from the barrel. The drive includes a hammer received in the barrel. The hammer reciprocates longitudinally within the barrel for contacting and expelling the terminal clip from the barrel. A cam guide is connected to the drive. A cam plate having a cam track is pivotally connected to the barrel. The cam guide engages the cam track such that the cam plate pivots back and forth as the drive is moved distally and proximally relative to the barrel. At least one finger is connected to the cam plate such that the finger engages and advances the clip string end of the clip receiving cavity as the cam plate pivots back.

1. A method of applying clips to reinforcing bars to connect the reinforcing bars, the method comprising: (a) placing a distal end of a clip applying apparatus against at least one of the bars;(b) manually forcing the apparatus against the at least one of the bars so that a proximally extending member moves distally relative to a barrel of the apparatus;(c) during step (b), moving a clip advance member laterally away from the barrel;(d) driving a clip from the barrel and onto the reinforcing bars with a hammer;(e) manually releasing the downward force on the apparatus and moving the proximally extending member proximally relative to the barrel; and(f) during step (e), moving the clip advance member laterally toward the barrel and moving another clip laterally into the barrel. 2. The method of claim 1, further comprising: repeating steps (a)-(f) multiple times to apply multiple clips of a string of connected clips, the string extending laterally from the barrel. 3. The method of claim 1, wherein: the distal movement of the proximally extending member in step (b) also moves the hammer distally in step (d), the hammer and the proximally extending member being rigidly connected together. 4. The method of claim 1, wherein: step (c) further comprises camming the clip advance member laterally away from the barrel. 5. The method of claim 1, wherein: step (d) further comprises manually forcing the hammer distally within the barrel to drive the clip from the barrel. 6. The method of claim 1, wherein: step (d) further comprises pulling a trigger and automatically driving the clip from the barrel. 7. The method of claim 1, wherein: step (e) further comprises moving the proximally extending member proximally with a spring. 8. The method of claim 1, wherein: step (f) further comprises moving the clip advance member laterally toward the barrel with a spring. 9. The method of claim 1, wherein: when the clip advance member moves laterally relative to the barrel in steps (c) and (f) the clip advance member pivots relative to the barrel.
