Assembling a Torpedo — It Requires 

 Almost Every Type of Workman 



A TORPEDO which will soon find its 

 way into the hold of a United States 

 warrior of the sea is interestingly depicted 

 in the photograph on this page. The pro- 

 pelling machinery, the compressed-air valves 

 and the firing mechanism have just arrived 

 from the factories. These parts are being 

 assembled in the torpedo on a naval barge 

 "somewhere" along our coast. 



Note the men working at the tail of the 

 torpedo. In the small space but twenty 

 inches in diameter they have placed the 

 powerful little air turbine which will drive 

 the twenty-five-hundred-pound projectile 

 at a speed of forty-five miles an hour! 

 They are adjusting this turbine, prior to 

 mounting the gyroscope in place at the very 

 end of the tail. 



The compressed-air tank is already in its 

 place in the center of the three compart- 

 ments of the torpedo. The tank will hold 

 air under the enormous pres- 

 sure of two and a quarter tons 

 per square inch. 

 No wonder this air 

 can propel the tor- 

 pedo at such great 

 speed when fed into 

 the turbine. 



There is little 

 time lost in the as- 



sembling after the interior "fine work" is 

 done. One man does not perform his task 

 and make way for the next. As is seen in 

 the photograph above, while the man in the 

 foreground is setting in the firing -pin 

 mechanism, the finishers and adjusters are 

 busy on the other portions and the painter 

 is polishing off the nose. 



A Self-Filling Pipe— It Works Like 

 a Self-Feeding Stove 



IF you are tired of filling that pipe of yours 

 so often you may be glad to know that a 

 self-filling pipe has been invented. James 

 H. Hoefler, of Kentucky, has devised a pipe 

 which has a tobacco magazine and which 

 fills itself without troubling the smoker. 



The great difficulty in making magazine 

 pipes is to prevent the tobacco from clog- 

 ging. This Mr. Hoefler has prevented by a 

 clever arrangement of the mag- 

 CoMapsible azine in telescopic sections, 



tobacco tube 



Removable stopper^' 



The self-feeding magazine attachment for a 

 pipe. It makes a "smoke" an all-day affair 



each section holding 

 its own tobacco. All 

 sections are collaps- 

 ible. The magazine 

 may be attached to 

 any pipe. So, on a 

 fishing trip, for in- 

 stance, all you need 

 do is to fill the maga- 

 zine and you can 

 smoke all day long.
