Fastener driving tool with an automatic nose chamber guide member
A fastener driving tool with an improved nose chamber guide member is provided for driving fasteners of at least two different lengths. Multiple fasteners in a magazine are guided toward a driving bore to be driven by a driver blade. A nosepiece defines a passageway of the fasteners. The guide member is operatively connected to the nosepiece and is configured for transitioning between a first position and a second position relative to the nosepiece in a direction transverse to an operational flow direction of the fasteners. In the first position, the guide member is disposed to align with the driving bore for allowing driving of the fasteners having a first length. In the second position, the guide member is disposed out of alignment with respect to the driving bore for allowing driving of the fasteners having a second length, which is longer than the first length.

a nose chamber guide member supported by the nosepiece, wherein the nose chamber guide member is movable relative to the nosepiece between a first position and a second position along a linear axis positioned transverse to a feed direction of the fasteners from the magazine to the driving bore;
wherein when the nose chamber guide member is in the first position, part of the nose chamber guide member is substantially aligned with the driving bore to enable driving of fasteners having a first length, and
wherein when the nose chamber guide member is in the second position, the part of the nose chamber guide member is out of alignment with the driving bore to enable driving of fasteners having a second length that is greater than the first length.
11. The fastener-driving tool of claim 10 , wherein the linear axis is perpendicular to the feed direction of the fasteners from the magazine to the driving bore.
12. The fastener-driving tool of claim 10 , which includes a biasing element that biases the nose chamber guide member to the first position.
13. The fastener-driving tool of claim 12 , wherein the biasing element includes a compression spring.
14. The fastener-driving tool of claim 10 , which includes a chamber attached to the nosepiece, wherein at least part of the nose chamber guide member is within the chamber when in both the first position and the second position.
15. The fastener-driving tool of claim 14 , which includes a biasing element that biases the nose chamber guide member to the first position.
16. The fastener-driving tool of claim 15 , wherein at least part of the biasing element is within the chamber.
