COMBINED PIPE WRENCH AND MONKEY WRACH. The wrench illustrated herewith differs materially from the ordinary in the fact that the usual screw mechanism is entirely dispensed with and the jaws may be instantly opened or closed to any desired ex tent. The wrench is also provided with a removable jaw piece which may be quickly ap plied to adapt it for use in gripping pipe or round work. Fig. 1 illus trates the wrench with the pipe-grip ping attachment applied thereon while Fig. 2 shows the wrench adapt ed for ordinary use. In this view the lower jaw is cut away to show the interior details. It will be observed that the ratchet mechanism with which this wrench is equipped in place of the screw mechanism is con trolled by a button A. that projects from the forward face of the lower disengaged from the ratchet teeth permitting the jaw to be moved downward on the shank of the wrench. A spring C serves to hold the dog in engagement with the ratchet teeth when the button A is released. It is not necessary to operate the button A when closing the jaws on a piece of work but merely when it is desired to open them. The pipe-gripping device con sists of a slotted member which may be fitted over the shank of the tool and is provided with inwardly inclined teeth as shown in the illustration. The in ventor of this improved wrench is Mr. Charles Waller of Hamilton Wash. COMBINED TIDIER AND DISTRIBUTER FOR INTERNAL COMBUSTION ENGINES. The speed of an internal-combustion engine is com monly regulated by varying the time of the spark with respect to the position of the piston. In the case of a multiple-cylinder engine the casing of the timing de vice carries a number of terminals which contact in succession with an inner rotatable member and the casing is mounted to oscillate for a limited distance in order to vary the time of the spark as above re ferred to. A disadvantage of this system is the fact that the casing cannot be held rigid and the time of the spark cannot be accurately con
