WILLIAM Y. FUQUA, OF HOUSTON, TEXAS.
PACKING MECHANISM FOR OIL AND WATER WELLS.Specification of Letters Patent.
Patented Feb. 9, 1915.
Application filed December 4, 1912. Serial No. 734,825.
To all whom it may concern:
Be it known that I, WILLIAM Y. FUQUA,
a citizen of the United States, residing at
Houston, in the county of Harris and State
5 of Texas, have invented certain new and
useful Improvements in Packing Mecha-
nism for Oil and Water Wells, of which the
following is a specification.
My invention relates to new and useful
10 improvements in packing mechanism.
The object of the invention is to provide
a mechanism of the character described de-
signed to be used in wells for the purpose
of casing off water.
15 As is well known, in boring an oil well a
water vein is often encountered as well as oil
and the water becomes mixed with the oil
and otherwise interferes with the boring of
the well.
20 It is the object of this invention to pro-
vide a device whereby the water may be
entirely cased off from the oil so that it will
not become mixed therewith or escape into
the bore and be discharged to the surface.
25 With the above and other objects in view
the invention has particular relation to cer-
tain novel features. of construction, opera-
tion and arrangement of parts an example
of which is given in this specification and
30 illustrated in the accompanying drawings
wherein:
Figure 1 is a sectional side elevation of
the device showing the position it will as-
sume when .it is in use, the inclosing fabric
35 being removed so as to expose the rib. Fig.
2 is a sectional side elevation showing the
position it will assume when being lowered
into or withdrawn from the well. Fig. 3 is
a sectional view of the device taken on the
40 line a-a of Fig. 1, and showing the same in
the position as shown in Fig. 1, a portion of
said device being broken away. Figs. 4 and
5 show a plan and edge view respectively of
one form of the supporting ribs used in the
45 construction of the device, and, Figs. 6. and 7
show plan and edge views respectively of
another form of ribs employed.
Referring now more particularly to the
drawing wherein like numerals of reference
50 designate similar parts in each of the figures
the numeral 1 designates the upper section
of the pipe through which the oil is con-
ducted, from the bore; connected to this sec-
tion is a short pipe sectionQ-of considerably
55 larger diameter, these two sections being
united by means of a reducing nipple 3, thisnipple being connected to the respective
pipe sections 1 and 2 by means of the ordi-
nary collars 4 and 5. Extending up into the
pipe section 2 from beneath is another pipe 60
section 6 considerably smaller in diameter
than section 2 which carries an enlarged
head or collar 7 at its upper end, said head
fitting closely in the section 2 and closely
surrounding said section 6 is an outwardly 65
threaded cuff 8 which is designed to be
screwed up into the inwardly threaded lower
end of section 2 and to prevent the with-
drawal of the head 7 from the said section 2.
Closely surrounding the section 6 and. be- 70
neath the cuff 8 is a sliding collar 9 which
has free vertical movement relative to sec-
tion 6 but whose downward movement is
limited by means of the annular shoulder 10
which is integral with the section 6 and ar- 75
ranged beneath the collar 9; pivoted to the
lower end of the cuff 8 and radiating there-
from are a plurality of inflexible ribs 11
and pivoted to the upper end of the sliding
collar 9 and radiating therefrom are a cor- 80
responding number inflexible radiating ribs
12; the outer' free ends of the respective
ribs 11 being hinged to the outer ends of
the corresponding ribs 12, as shown in Figs.
1 and 2. These ribs are covered on the out- 85
side by means of a strong oiled fabric cover-
ing or some similar strong flexible material;
this covering is secured in place on the ribs
iii any preferred manner as by being sewed
thereto or in any other way which may be 90
preferred.
When a stream of water has been encoun-
tered and it is desired to case the same off
and stop the flow thereof up into the bore,
the device is assembled as shown and at- 95
tached to a string of pipe of sufficient length
to bring the casing device to the proper
point when the pipe has been lowered in the
bore. The upper section 1 is then forced
downwardly and the collar 9 seats upon the 100
shoulder 10 and as additional force is ap-
plied to the section 1 the ribs 11 and 12 are
forced to spread outwardly in the manner
of an umbrella carrying the fabric 13 out
with them and said ribs are gradually 105
forced into the soft sides of the bore until
the lower end of cuff 8 seats upon the upper
side of collar 9 and the fabric 13 being im-
pervious to liquid passage thus entirely cuts
off the flow of water therethrough and pre- 110
vents the water of one side, thereof from
mingling with the oil of the other side. The1,127,428.
