Taking Snap Shot Action Pictures at 

 Night with a Flashlight Pistol 



O take flashlight photographs the usual 



procedure for the 

 photographer is first 

 to set up his camera 

 and tripod, open the 

 lens with one hand, 

 and then fire the 

 flash powder with 

 the other. Because 

 of all this prepara- 

 tion, it has been im- 

 possible for the 

 photographer to 

 take instantaneous 

 or snap shot photo- 

 graphs by flashlight. 

 Now, with the aid of 

 a novel flashlight 

 pistol invented by a 

 California man, the 

 tripod is dispensed 

 with. 



The operation of 

 the pistol is purely 

 mechanical. The 

 fact that the force of 



the powder explosion operates a lever which 

 in turn manipulates the camera shutter, 

 relieves the photographer of all responsi- 

 bility. From the diagram it will be seen 

 that the force of the explosion raises a steel 

 lid which operates the control wire to the 

 shutter. Hence the shutter is opened and 

 closed at exactly the instant the flash is at 

 its brightest. There is no possibility of an 

 over or under-exposure. However the 

 device permits the use of the various grada- 

 tions of shutter timing. A spring-operated 

 spark-wheel sets off the powder charge.

shops and offices of the railroad to facilitate 

 the collection, and a baling machine has 

 been installed by the company, which bales 

 1,500 tons of old papers annually. This 

 waste paper is sold 

 for fifteen dollars per 

 ton, so that about 

 $22,500 is realized 

 by the company in 

 this way. In New 

 York city, a social 

 workers club is pay- 

 ing one cent to the 

 children of the poor, 

 for every pound of 

 old paper they bring 

 to the club head- 

 quarters. 



By holding the 

 camera in the

 in the left an

 flashlight photo-

An Elastic Cord 



for the Sash 



Curtain 



AN extremely 

 » simple and in- 

 expensive device for 

 \stener holding sash cur- 

 tains employs an 

 elastic cord which is drawn 

 through the curtain in the 

 usual way, the ends being 

 clamped down at the sides of 

 the window as shown in the 

 illustration. The elasticity of the 

 cord makes it adjustable to any 

 window. When it is necessary to 

 remove the curtain for laundering 

 or to wash the window, one end is 

 undamped and the curtain is 

 slipped off the cord ; then the cord 

 is looped up out of the way on the other 

 clamp. The cord is always taut and there 

 is no possibility of sagging.

account of the shortage of 

 paper, old newspapers and other 

 waste paper have risen to an im- 

 portant place in the commercial 

 world. Today the man who throws 

 down his paper in the cars after he 

 has finished reading it is regarded as 

 somewhat of a spendthrift. On the 

 Pennsylvania Railroad, for instance, 

 waste papers are now carefully 

 collected. Ten thousand bags have 

 been distributed to stations, work-
