<p>A cam locking pin for temporarily securing together a pair of members such as plates having confronted faces and alined apertures. The pin is inserted through the apertures, as from below. A pawl member at the upper end of the position is pivoted ninety degrees to a position in which its long dimension lies crosswise of the pin and apertures and that dimension is greater than the diameter of the pin so that the pin cannot fall out of the apertures. A lower portion of the pin depends below the bottom plate and has lug means thereon for receiving a swingable tool having cam or eccentric surfaces acting against the lower plate to draw the plates together. The cam is so shaped as to retain its locking position until released.</p> |
