Thelock we show here, very simply performsthis function. Our illustrations repre-sent a pair of couplers with the newlocks, the couplers connected, but notlocked, being shown in Fig. I.

The chain may then be attachedto the hose clamp if desired. The otherend of the lock has a projection shapedlike a cylinder split through its axis and an opening of similar shape to engage thesemi-cylindrical part of the adjacentlock. .\ thumb screw near the middleserves to force the locks upward when en-gaged and so pull the couplers tightly to-gether like a toggle joint. The point ofthe screw bears against the body of thecoupler and is rivetted over, to preventworking out of the lock. This lock ismade of malleable iron and has sufficientplay in the eye of the coupler to allowof readily inserting the half
