PATENT OFFICE,
THIIOMAS IH. LOGAN, OF THE UNITED STATES ARMY.
ARTESIAN-WELL BORER.
SPECIFICATION forming part of Letters Patent No. 444,839, dated January 20, 1891.
Application fled Maich 16, 1890. Serial No, 344,040%. (No model,)Tlo all whons it 7ay co1nceri:
Be it known that I, THOMAS H. LOGAN, Of
the United States Army, at present stationed
at Fort Hancock, in the county of El Paso
5 and State of Texas, have invented a new and
Improved Artesian-Well Borer, of which the
following is a full, clear, and exact descrip-
tion.
This invention relates to earth or rock
io augers of the class employed in boring Arte-
sian wells, the object of the invention being
to provide an efficient, simple, and durable
anger or borer, and one which will be actu-
ated by the weight of the connecting-rods
15 and sink wells in rock, gravel, earth, or sand
without the use of water.
To the ends above named the invention
consists of certain novel constructions, ar-
rangements, and combinations of elements
zo which will be hereinafter fully described, and
specifically pointed out in the claims.
Reference is to be had to the accompanying
drawings, forming a part of this specification,
in which similar figures and letters of refer-
25 ence indicate corresponding parts in all the
views.
Figure 1 is a side view in partial section of
my improved Artesian-well borer, parts being
broken away. Fig. 2 is a central vertical sec-
30 tional view taken from the direction of the
arrow a, shown in connection with Fig. 1.
Fig. 3 is a detail view upon an enlarged scale
of the cap of the main tube. Fig. 4 is a sec-
tional view on line 4 4 of Fig. 5. Fig. 5 is an
35 enlarged vertical sectional view of the upper
portion of the main tube and its connections.
Fig. 6 is a cross-sectional view on line 6 6 of
Fig. 7. Fig. 7 is an enlarged sectional detail
view of the lower portion of the main tube
40 and its connections. Fig. 8 is a plan view of
the tool employed in boring rock, and Fig. 9
is a side elevation thereof.
In the drawings, 10 represents the main
tube of the borer, which tube is by prefer-
45 ence made in sections b and c, that are united
by an internal sleeve 11. Within the tube
10 I arrange a tube 12, that is held in the
section c by the sleeve 11 and by a collar 14,
held in place just within the lower end of the
50 tube 10. This inner tube 12 has a number
of inwardly-extending projections 15, that fit
within the spiral grooves cd, formed in a pro-jection 16, that extends down from the rod-
coupling shank 17, said shank proper being
squared or irregularly formed to receive a 55
wedge-shaped collar or sleeve 18, the upper
end of the shank being threaded to engage
the stock of acoupling-eye 19. To the upper
end of the tube 10 I secure a cap 20. Within
the top of this cap 20 there is arranged an 6o
apertured partition 21, which carries plates
22, said plates being centrally apertured and
formed with slots e, through which there ex-
tend studs or pins f, that are carried by the
partition 21. The plates 22 each carryapiv- 65
otally-mounted dog 23, having serrated edges
g, said dogs being arranged so that they may
be extended outward through slots h, that
are formed in the cap-walls. This construe-
tion is provided so that when the shank 17 is 7o
lowered to the position in which it is shown
in Figs. 1 and 2 the wedge-shaped collar 18
will bear upon the plates 22 and the dogs will
be moved outward to a position such that
their edges g will bear against the well-cas- 75
ing and hold the tube 10 against any rotary
motion.
A portion of one side of the lower end of
the tube 12 is cut away to provide for the
mounting of a hooked pawl 25, which said 80o
pawl engages a ratchet 26, formed at the up-
per end of the stock 27, the stock being held
against any upward motion by a diaphragm
or partition 28, arranged within the tube 12,
and against any downward motion by an in- 85
ternal collar 29, that is carried by the tube 12.
To steady and guide the stock I provide the
collar 14 with a bearing-collar 30, which abuts
closely against the peripheral face of the
stock, all undue play being prevented by a 90
collar 31, that is carried by the stock, the col-
lar being held to place upon the stock by a
set-screw 32, which screw may be turned in-
ward so that it will bear against the shank
33 of an auger 34. 95
In order that the earth or cuttings gathered
by the auger 34 may be housed and raised
from the bore made by the auger, I provide
a casing 40, that fits about the tube 10, the up-
per end of the casing being formed with an coo
inwardly-extending flange 41, that overlaps
an annular shoulder 42, formed at the lower
end of the said tube 10, all upward movement
of the casing at times when the instrument is
