Abstract
A housing for a power tool having a power source, includes a fuel cell chamber configured for attachment to the power source and dimensioned for operationally receiving a fuel cell in either one of a first orientation and a second orientation.
Claims12
A housing for a power tool having a power source, comprising:
- a fuel cell chamber configured for attachment to the power source, having a fuel cell door at one end and being dimensioned for operationally receiving a fuel cell in each of a first orientation and a second orientation;
- and
- a shelf mount disposed in said chamber and configured for axially securing a fuel injector in place when the fuel cell is in the first orientation, and for supporting a bottom of the fuel cell when the fuel cell is provided with a mechanical fuel dispenser in the second orientation, said shelf mount defining a distance between said fuel cell door that fully accommodates the fuel cell in said fuel cell chamber in said first orientation, and permits operational engagement between the mechanical fuel dispenser and said power source in said second orientation.
A combustion-powered fastener driving tool, comprising:
- a power source located within a power source housing;
- a handle housing including a fuel cell chamber configured for attachment to said power source and dimensioned for receiving a fuel cell in each of a first orientation and a second orientation;
- and
- a primary handle having a first end connected to said fuel cell chamber and a second end connected to a battery housing, a secondary handle connected at one end to said battery housing and at a second end to a support strut, said support strut connected to said fuel cell chamber housing, said power source, said fuel cell chamber and said battery housing being generally parallel to each other, said handle and housing configuration enhancing user control when a lame capacity coil magazine is fitted to said tool.
