andMALACsA JOSiH MCLAUGHLIN, citizens.
ofth e UhinteddStates residing at Sourlake, in
5 the con v ot Hai dinand State of Texas, have
inveitedcertain new and useful Improvements,
in:llydi auilic Swivels;' and we do hereby de-
hlarethefollowino to be a full, clear, and ex-
act description of the invention, such as will
[0 enable others skilled in the art to whih it ap-
pertains to make and use the same.
Our invention relates to that class of hy-
draulic swivels designed for use in connection
vith'rotar'ywell drilling machines where wa-
5 tr cis 'onducted under heavy pressure from a
pump to the point of a drill secured to the
lover end of a rotating tube.
The in entior contemplates an organization
of operating elements whereby a supply-
20' hose may besupported in a given position and
setained againstmoveinent -in relation to the
rotatingg drill-tube' while supplying it with
water.
The device insists primarily, of a swivel-
2.5 block and supporting means therefor, a tubu-
lar swivel-stem extending through said block,
and means provided for rotatably supporting
same.
Other objects and advantages of this inven-
30 tion will appear-in the following description,
and the novel features thereof will be particu-
larly pointed out in the appended claims, it
being understood that changes in the form,
proportion, and minor details of construction
35 may be resorted to without departing from
the spirit or sacrificing any of the advantages
of the invention.
In the drawing the figure represents I lon-
gitudinal vertical central section illustrating
40 the construction of a hydraulicswivel embody-
ing thefeatures of. our-invention.
In making wells by the rotary process it is
necessary to continually force water to the
drill-point attached to the lower end of the
45 well-casing and rotate said casing while peing
supplied with water. Several devices have
been invented for accomplishing this; but all
use a hose-stem and- swivel-stem, also other
complications for the purpose. As disclosed
50 in the accompanying drawing, our swivel with
but one stem supports the water-supply pipe
in a stationary condition while the casing is
rotated, thus much more simply attaining the
desired object.Patented Sept. 26, 1905.
Referring more particularly to the drawing, 55
A denotes a bail or clevis.of any preferred
form- enlarged and apertured at its ends, as at
B B,. and having bearings on the projecting
reduced ends of the hollow trunnion-block C,
which block revolubly surrounds the swivel- 6o
stem D. The trunnion-block C, as suggested.
is hollow and is formed with an 'interior an-
nular chamber for purposes which will be
hereinafter made apparent. The swivel-stem
D is exteriorly threaded at the lower end and 65
a casing-bushing E fitted to same. A jam-
collar F is also threaded upon it for firmly
locking the two and obviating danger of said
bushing working loose and unscrewing with
the casing-section to be connected to the lower 70
end of said bushing. A collar G surrounds
stem D just below and preferably formed in-
tegral with the trunnion-blockC. .It is cham-
bered, forming a stuffing-box H, which is filled
with suitable packing material. A gland 1 is 75
threaded into the lower end of said collar G
for adjustably closing said stuffing-box H and
retaining the packing in position.
Mounted within and resting upon the-inner
lower surface of the trunnion-block- C i an 8o
annular collar J, and a similar collar K; is
placed above collar J, the-space between said
collars being maintained by means of conical
rollers L L or other antifriction devices tray-
eling within annular raceways M and N, 85
formed in the said collars for limiting the lat-
eral play of said cones.
Forming part of the swivel-stem is a solid
collar 0, the lower side resting upon collar
K. A head P, secured .by stud-bolts Q, closes go..
the annular chamber of trunnion-block C and
rests upon collar 0, whereby a tight closure
is made for it, also for collars J and K, retain-
ing all against vertical movement, besides
forming a receptacle that 'may be filled with 95
oil and kept free of dirt.'-
R is an extension of the head P. It is ex-
teriorly threaded and chambered, forming an
annular stuffing-box S, having a .gland T ad-
. justably secured in position by a superim- Too
posed annular cap U, interiorly threaded and
provided with an inner annular shoulder rest-
ing upon the flange of gland T, whereby the
packing is adjustably compressed) around the
swivel-sten1 D. A jam-collai V,- screwed on 105
upper end of gland- Tprevents the weight of
hose resting'upon the packing.- A gooseneck
.w is threaded into the uppei- end of the gland
