The Myers Hydraulic j 
Spray Pump 
The Myers Hydraulic Spray Pump is constructed 
with unusual capacity to meet the demands for a spray 
pump capable of doing a large amount of work in an 
effectual and satisfactory manner. It is provided with 
an air chamber having a capacity of nearly lo gallons, 
fitted with valves and fixtures strong enough to resist any 
pressure that may be put upon it. 
THE PUMP 
The pump proper is made of brass, has a solid 
plunger, with long lever; is equipped with the latest 
improved suction and retaining valves, which have large 
openings and allow free passage of the liquid. These 
valves can be readily taken out by removing the two 
bolts marked "CC," without disarranging any other 
parts of the pump. A common wrench is all that is 
required to dismantle the pump entire. This construction 
is the most simple, and will be readily understood by 
the operator. 
The liquid is discharged into the air chamber from 
the bottom, passes through a specially constructed de- 
vice, which causes the liquid to piss in with a circular 
motion, which makes an agitator that always keeps the 
liquid stirred. 
The air chamber is 36 inches long, from the top of 
which is suspended a }{-'uich lube, reach- 
ing within yi inch of the bottom, and is 
connected with the discharge at the top, 
thus taking the liquid from the bottom 
of the air chamber. This arrangement 
allows the pump to be drained of all 
liquid. The

air cham- 
ber is pro- 
vided with 
two dis- 
c h a r g e 
valves, 
"B," of 
Jenkins pattern, arranged so that one or both of the sprays can be used 
at a time. 
The discharge valves are fitted with hose nipples and female ends of 
/^2-inch brass hose coupling. The entire arrangement of the pump and air 
chamber is assembled on one base plate in such a manner that it may be 
subjected to extreme hard usage in charging the air chamber with heavy 
pressure, without impairing any of its working parts. 
The base plate is large, and is provided with holes for fastening down 
the pump. 
When the operator desires to obtain more air pre,ssure when using the 
pump, he opens the cock "A," which, by rapid working of the lever, sup- 
plies additional air and gives more pressure. This is more desirable in 
draining the pump. The pump is also provided with a brass shut-off drip- 
cock, wliich drains the cylinder complete.
