STEPHEN A. HORTON, OF CLARKSVILLE, ASSIGNOR TO THE HORTON DEEP
AND ARTESIAN WELL COMPANY, INCORPORATED, OF DALLAS, TEXAS.
WELL-DRILLING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 554,820, dated February 18, 1896.
Application filed September 7,1894. Serial No. 522,380. (No mocde.)To all whom it inay concern:
Be it known that I, STEPHEN A. HORTON, a
citizen of the United States,residing at Clarks-
ville, in the county of Red River and State of
5 Texas, have invented a new and useful Well-
Drilling Apparatus, of which the following is
a specification.
My invention relates to well-drilling appa-
ratus forboring Artesian and other wells, and
io the objects in view are to provide simple, effi-
cient and durable means for expanding or
spreading the reamer-blades after the bit-car-
rying devices have been lowered sufficiently
to arrange the reamer-blades below the plane
15 of the lower end of the tubular drill-rod; to
provide expanding devices actuated by the
pressure of the water admitted to the drill-
rod for the purpose of freeing the boring-
blades from cuttings, such pressure of the
20 water as above being assisted by gravity; to
provide means for supporting the sections of
cable by which the drill-bit-carrying parts are
suspended and lowered into the drill-rod,
whereby as successive sections of the drill-
25 rod are added similar sections of the support-
ing-cable, said sections being of equal length
with the sections of drill-rod, maybe attached;
to provide improved means for securing the
reamer-blades in the reamer-stock, and to
30 provide an improved expansible packer ar-
ranged upon the drill-bit-carrying parts and
adapted when expanded to fit snugly in the
drill-rod and prevent water admitted to the
drill-rod from passing down around the core
35 and deflect it into the bore of the core, for a
purpose hereinafter explained.
Further objects and advantages of the in-
vention will appear in the following descrip-
tion, and the novel features thereof will be
40 particularly pointed out in the appended
claims.
In the drawings, Figure 1 is a view of a
well-drilling apparatus embodying my inven-
tion, the core, bit, reamer, and connected
45 parts being shown in side elevation and the
drill-rod in section. Fig. 2 is a detail view
of the cutting device, core; and packer, the
packer and the upper end of the core being
shown in section. Fig. 3 is a detail sectional
50 view of the reamer and connected parts,
showing the means for expanding the reamer-blades. Fig. 4 is a similar view of a slightly-
modified form of means for communicating
motion to the reamer-blades from the expan-
sion devices. Fig. 5 is a similar view show- 55
ing another modified form of reamer-blade-
expanding devices. Fig. 6isadetailsectional
view on the line 6 6 of Fig. 2, to show the
channels or ports whereby water flows from
the interior of the core to the outlet-perfora- 6o
tions in the drill-bit when the reamer-blades
are expanded. Fig. 7 is a detail sectional
view on the line 7 7 of Fig. 3, to show means
for mounting the reamer-blades in the reamer-
stock. Fig. 8 is a detail sectional view of the 65
upper terminal section of the drill-rod, show-
ing the upper section of the supporting-cable
and the device for suspending such cable in
the drill-rod within reach of the operator dur-
ing the drilling operation. 70
Similar numerals of reference indicate cor-
responding parts in all the figures of the
drawings.
1 designates a tubular drill-rod formed in
detachable sections which are connected at 75
their contiguous extremities by means of
couplings 2, the lower section, 3, of the drill-
rod forming a bit-socket and being con-
structed with interior ribs 4 for engagement
with pockets 5 formed on the surface of the 80o
core 6, said pockets being provided by notches
cut in lateral extensions 7 of the exterior ribs
8 and having beveled lower sides, as shown
at 9. All of this construction is clearly illus-
trated and described in my application,Serial 85
No. 507,891, filed April 17, 1894. These cores
are hollow or tubular in construction, and
attached to the lower extremity thereof and
having exterior ribs 10 arranged in alignment
with the exterior ribs on the core is a reamer, 90
having a stock 11 and expansible blades 12
arranged in diametrical or transverse align-
ment. When the parts are in operative po-
sition, as shown in Figs. 1 and 3, said reamer-
blades are expanded, and their outer ends 95
project beyond the surface of the drill-rod,
and beyond the outer surface of a wear-sleeve
13, which is threaded upon the lower extrem-
ity of said drill-rod, whereby as the drill is
operated said blades enlarge the opening oo
formed by the usual drill-bit to form a hole
of sufficient diameter to receive the drill-rod.
