It will be seen,Ijy referring to tlie illustration, that it consists of a combinedupper jaw and handle, a lower or sliding jaw, an adjustmentspring and a steel rack set into the lower face of the taking the wrench .as shown in the illustration a slight pres-sure of the thumb will depress the movable jaw against therctistatice of the spring and release its engagement with the can then be opened or closed as desired, when the release ofthe pressure causes it to again engage the rack. On all wrenches up to 12 in. the adjustment is within .04 of an. inch and on the 15 in. and 18 in. sizes within 1/16 of an inch. Thewrench is substantially built of carbonized steel, and is groundand polished. It is claimed that these wrenches have no backlash, and that they will not under any circumstances becomelocked on a nut. They are very quickly adjusted and can beused in either hand. 248 AMERICAN ENGINEER AND RAILROAD JOURNAL. NEW FULL UNIVERSAL TRIPLE GEARED RADIALDRILL. The universal radial drill has heretofore proven entirely inade-quate to the severe duty imposed upon the modern plain armradial, but its field of usefulness in machine shops is so large thata redesign was imperative. Up to the present time the universalradial has been incapable of driving to the limit high speed steeldrills, principally because of lack of power and springing of thearm. The new machine shown in the accompanying view repre-sents a radical departure in design and the highest developmentin this type of drill, which fulfil
