An exhibit at Cape May which was always sur-rounded by a knot of interested observers was a continu-ously acting ratchet drill, made by the Schuttler of 10^ Dearborn street. Chicago. represented byilr. Crafta \V. Higgins. We present illustrations ofthis ingenious and labor-saving device. The distin-guishing feature of this form of drill is the continuousaction of the drill under both the forward and back-ward movements of the lever or handle. With bothmotions the drill steadily cuts its way into the steel oriron. There is no lost motion—every inch of move-ment of the lever being effective. This enables the. \VoKKlX(i PaKTS of CoXTIXI CIS Rat. HET operator to do a given piece of work in jusl half thetime required by a common ratchet drill with whichonly the stroke of the handle in one direction is ef-fective. The double action feature of the Schuttlerdrill is particularly effective when obstacles permitthe working of the lever with very short strokes movement of the handle an inch or two only oper-ates the drill, and the additional work done by the re-turn strokes becomes in such cases very important. The mechanism by which the continuous cuttingaction of the drill is accomplished is clearly shownin the smaller cut. With the forward motion of thehandle one pair of spur and conical gear is broughtinto action and with the backward motion the the motion of the handle is changed from forwardto backward, or vice versa, a dog comes into engage-ment with the pair of gear to be thrown out of opera-tion and holds them from turning.
