- 2. An outrigger as specified in claim 1 in which the said support member has a circular gear tooth portion thereon, and a movable slide having gear teeth in mesh with said circular gear teeth is slidably connected to the said outer member and is movable longitudinally thereon.
- 3. An outrigger as specified in claim 2 in which the said inner member carries a pin for engaging the said slide, the said outer member provided with a slot for such pin, and the pin is arranged to engage the said slide to pivot the said support member from near the frame to a position away from the frame during a predetermined portion of the outward extension of the outrigger.
- 4.
