HANDLING THE ACID. 53 
SIMPLE METHOD OF REMOVING ACID FBOM DRUMS AND CARBOYS. 
The writer has ai 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 he made of some of the best methods 
which have been brought to notice to obviate this difficulty. 
From drum*. 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 
FlO. 15.— Lead-lined tank used in San Bernardino County for removing sulphuric acid from drums and 
for filling jugs. (Original.) 
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 thenTevolved through a quarter 
circle, permitting the drum to be rolled out over the lead-lined tank, 
into which the acid is then allowed to How. 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 (low is regulated. 
Another w\y 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
