New Storey Portable Electric Drill — The general adoption of electricity in machine shops and factories favors the use of a compact and efficient port able electric drill such as that placed on the market by the Storey Motor & Tool company of Philadelphia and illustrated in the accompanying cut. This machine is adapted for drilling pig-iron and copper for test work; drilling rails and for various other kinds of work. Owing to the type of the motor, which is entirely enclosed, it is suitable not only for indoor work, but can also be used for outside purposes without requiring any specially arranged covering for its protection. The outfit complete consists of motor and drill combined, together with a regulating rheostat for obtaining any desired speed, and a drum with 100 feet of flexible cord, all mounted on a truck, with or without a rack for holding material to be drilled. These machines drill in sizes up to i !2 inches in steel and two inches in cast-iron, and are furnished with both automatic and hand feeds These drills can also be placed on a table or in any stationary position and will cover a large range of work of different classes. As an illustration, an application may be mentioned where two of these drills are mounted on bed-plates, one at each end of a large callender roll, drilling two holes in flanges at the same time and tapping them in the same operation, before the roll is moved. Another adaptation of this drill is where it is fitted with a telescoping shaft and is used in yards for drilling holes in the construction of switches and crossings for street car and railroad work. |
