The numeral 4 designates the tubular working

A tubular plunger 6 works through the working 1
barrel and is spaced inwardly therefrom and has
the upwardly opening cup ring assembly ‘I there
on forming a close ?t with the working barrel.
The upper end of the barrel 4 is attached to a
tubular hanger 8 whose upper end is?ared and 15

said pipe, or being separate from the‘ pipe, and form shown in Figs. 1, 4, and 6, the upper end of~
, said extension is upwardly ?ared, as at l0, and
suitably anchored therein.
with the above and other objects in view, the
invention has particular relation to certain novel
features of construction, operation, and arrange
ment of parts, an example of which is given in
this speci?cation and illustrated in "the accom
panying drawings, wherein:

sectional view, showing a modi?ed form of the
valve mechanism for controlling the advance of
?uid upwardly.

taken on the line 3-3 of Fig. 2.1
Fig. 4 shows a side elevation, partly in section,
of the upper portion of a slightly modi?ed form
of the type of pump shown in Fig. 1.
Fig. 5 shows a vertical sectional view of the
lower portion thereof.‘

Referring now more particularly to the draw
65 ings wherein like numerals of reference designate
varound. said reduced portion .is providedwi'th an
external annular groove ll.
.
‘
‘ The lower end of the plunger 6 is extended be- 30
neath the working barrel and has an external an
_ nular stop' 12 thereon.
The plunger may be re-
,
ciprocated by a suitable power ‘at the ground sur
face through the instrumentality of the usual
sucker rod l3 whose lower end is connected to a 35
bell-shaped nipple it which, in turn, is secured
to the upper end of 'said plunger. _
. In the form shown in Fig; 2, the upper end of
the working barrel is attached to the lower end
of the hanger l5 whose upper end is upwardly
?ared to conform to the shape of and to ?t the
seat 3. Aboveand resting on the hanger i5 is
the cage l6, having the external radial lugs ll.
The ?ared portion of the hanger 15 has the deep’
sockets l 8 at its under side, and rods 19 have their
-upper ends anchored to the lugs l1, and extend
downwardly through bearings in the hanger, and
their lower ends have enlarged heads 20 in said
sockets.
The upper end of the hanger l5 has an annular
groove 21 in which a packing washer '22 is located.
A sleeve-like packing element 23 surrounds the
plunger 6 and its lower endis moulded into the
cage l6,'and seated in an annular groove in the
lower end of the packing element 23, there is a

The apparatus, as shown in Figs. 1 and 2, may
be assembled and let down into the well by means
of the sucker rod l3 until the hanger supporting
tne working barrel lands on the seat 3.
The -
sucker rod may then be lowered until the
