HANDLING THE ACID,

SIMPLE METHOD OF KEMOVING ACID FROM DRUMS AND CARBOYS. 



The writer has at times been obliged to employ rather awkward 

 methods in drawing acid from drums and carboys, and other fumi- 

 gators have doubtless met with the same trouble under like circum- 

 stances. Brief mention will be made of some of the best methods 

 which have been brought to notice to obviate this difficulty. 



From drums. — The best method of taking' acid from drums known 

 to the writer is that at present in use in San Bernardino County and 

 is shown in figure 15. The apparatus consists of a lead-lined tank 

 large enough to hold a drum of acid and having an outlet through

which the acid may be drawn into carboys, jugs, or whatever vessels 

 are preferred for field use. A drum of acid is rolled from the wagon 

 upon two parallel beams and along these beams onto a small turn- 

 table at the tank. This turntable is then revolved through a quarter 

 circle, permitting the drum to be rolled out over the lead-lined tank, 

 into which the acid is then allowed to flow. The acid may be drawn 

 as previously mentioned. The outlet is made of lead tubing, fitted 

 at the tank end with a lead valve by which the flow is regulated. 



Another very satisfactory way of drawing acid from drums came 

 to the writer's attention in examining some operations at Glendale, 

 Cal. It consists in the use of a short iron pipe threaded at one end
