Equipment Used Afloat, Ashore Marine Switchboard--Broken Drills--Bench Drilling Stand New Marine Switchboard Designed for Safety A marine switchboard, which is said to be absolutely safe to operate and of- fers no danger whatever to the passerby is one of the latest products of the Westinghouse Electric & Mfg. Co., East Pittsburgh, Pa. This board has no ex- posed contacts whatever. One could fall against it without the slightest dan- ger, and in fact even were the attempt deliberately made to reach live parts, it would not be successful unless part of the board were actually dismantled. This high degree of safety is desirable in any kind of service, but especially so on shipboard. The construction of this board is a radical departure from the standard type. It consists of panels of heavy sheet steel which are finished to resemble slate and are mounted on angle iron supports with cross beams to insure rigidity. Openings SWITCHBOARD FOR MARINE USE DESIGNED TO USE BROKEN DRILLS of the proper sizes are provided in the panels and into these the switches are accurately fitted. : Each switch is contained within a separate compartment and is fully en- closed on all sides. It is operated by means of an insulated handle which pro- jects through the cover. Below the handle is a door which gives access: to the fuses and permits their renewal, but this. door can not be opened unless the switch is in the off position and all reachable parts are dead. Nor can the switch be closed if the door -is open. These boards are supplied in any de- sired combination of panels, switches, meters, circuit breakers, rheostats, and other instruments, and in all capacities up to 600 amperes for 250-volt direct current, and 1000 amperes for 600-volt alternating current. To Use Broken Drills The Wayne Tool Mfg. Co., Waynes- boro, Pa. has developed a chuck for holding twist drills which have been broken at the shank. The design is simple, the chuck being composed of only seven parts: shank, casing, two pawls, two screws and a casing plate. The drill is ground to a 60-degree point at the broken end. This allows the drill to center itself automatically 431 on a 60-degree recess in the shank. 'On turning the casing the drill is iocked in place by the two pawls. Bench Drilling Stand A new bench drilling stand has been developed by the Black & Decker Mig. Co., for use in adapting electric drills to vertical use. The bracket carrying the drill can be raised or dowered on the vertical col- umn and is secured in any desired posi- tion by means of a split collar and clamping screw, The drill, also, may be swung clear of the base, makjng it possible to use it for drilling the ends of shafts and other parts of inconven- ient length. 'An extra long feed-lever gives a ratio of 6 to 1; this means that 100 pounds pressure applied to the handle causes the 'drill to work at 600 pounds pres- sure. In the base are six tapped holes to accommodate half-inch studs, used to dlamp the work in place. BENCH DRILLING STAND
