Economical Wiring for Bracket Outlets 



In wiring a house by the "knob-and- 

 tube," the conduit, or, in fact, by any 

 method, considerable material and labor 

 will be saved if the wireman locates the 

 bracket outlets in adjoining rooms, so 

 that the outlets will come directly oppo- 

 site each other. Where the wiring is 

 being installed in conduit, a short con- 

 duit nipple can be used to connect the 

 two metal outlet boxes, and all bending, 

 as well as the use of excessive lengths of 

 conduit, will be avoided. Where knob 

 and tube wiring is being put in, similar 

 savings will be effected if the bracket 

 outlets are intelligently located. Every 

 bracket outlet ought to be located a dis- 

 tance of 5 feet 6 inches f rom the finished 

 floor line, inasmuch as this is the stand- 

 ard height in residences in the United 

 States.

To Prevent Poured Lead from 

 Exploding 



When melted lead is poured about a 

 damp or wet joint, it "explodes," or scat- 

 ters, due to the pressure of the steam 

 suddenly generated. This trouble may 

 be averted by melting a small piece of 

 resin with the lead in the ladle, before it 

 is poured.

Flux for Wire Soldering 



Resin and wood alcohol make a good 

 soldering flux for electrical work. An 

 added advantage is that the joint will 

 not corrode. To prepare the paste, the 

 resin should be powdered and mixed into 

 the alcohol until a moderately thick con- 

 sistency is obtained. The paste should 

 be applied freely to the surfaces to be 

 soldered.

A Safety Hint for Motorists 



The possible danger of a "kick back" 

 from an automobile engine when it is 

 first cranked can be avoided if the crank 

 is turned several times before the battery 

 cells are switched on.

An Ingenious Taper Gauge 



Instead of using the ordinary taper 

 gauge for fitting tapers, as is the com- 

 mon practice, a tool machined according 

 to the accompany drawing may be used 

 with much better results. Thumb nuts 

 should be provided for the sliding bar, 

 so that it may be adjusted without diffi- 

 culty.
