Another object of the invention is to provide a tool
for the purpose described which includes a tubular re
ceptacle, open Áat its ends, adapted to be lowered in the
casing and having a support therefor V?rictionally and yield
ably engaging the inner wall ot the casing, an elongated
rod arranged concentrically within the receptacle and
adapted to be suspended `from a wire line, the rod being
movable reciprocally relative to »the receptacle and having
for, indicated generally by the numeral 4, which tric
tionally and yielda'bly engages the inner wall of the
10
casing 2.
"
An elongated rod 5 is arranged concentrically within
the element 3, and is ¿adapted »to be suspended rfrom a
wire line `6. The rod 5 is movable reciprooally relative
to the element 3, and has ya round Weighted member 7
on its lower'e'nd for abutment against the lower end of
the element 3», whereby the latter is supported on the rod
5, and a second weighted member l8 on its upper end
for «abutment »against the upper end of the element 3 to
urge the same downwardly relative to the casing 2.
A valve disc 9, which advantageously may be formed'
of resilient material, isv positioned on the rod 5 above the
member ’7 for sliding engagement with the inner wall
of theV element 3 adjacent its lower end, to provide a
a iirst enlargement on its lower end `for abutment against 25 closure therefor, when the rod 5 is in an elevated posi
tion below its uppermost position relative to theY ele-l
