GEORGE W. SLAUGHTER, JR., OF SAN AUGUSTINE, TEXAS.
WELL-DRILLING MACHINE.Specification of Letters Patent. Patented Aug. 4, 1914.
Application filed June 7, 1913. Serial No. 772,450.To all whom it may concern:
Be it known that I, GEonon W. S.AuGII-
rEn, Jr., a citizen of the United States, re-
siding at San Augustine, in the county of
5 San Augustine and State of Texas, have
invented a new and useful Well-Drilling
Machine, of which the following is a speci-
fica tion.
The present invention appertains to well
10 drilling machines, and relates more particil-
larly to. a novel and improved means fo
maniplllating Und actuating the drill cable.
One of the objects of the preseIlt invel l
tion is to provide a device of the nature in-
15 dcated which shall eliminate the use of a
walking beam and spud lever as are orcli-
narily employed in well drilling machines
for actuating the drill rope.
Another object of the present invention is
20 to provide a comparatively simple and in-.
expensive means for actuating the drill rope,
and for simultaneously feeding the drill
rope into the well as the drill works its way
downwardly.
25 With the foregoing general objects out-
lined, and with other 'objects in view, which
will be apparent. as the nature of the inven-
tion is better understood, the present inven-
tion resides in the combination and arrange-
30 ment of parts and in the details of construc-
tion hereinafter described and claimed, it
being understood that changes in the precise
embodiment of the invention herein dis-
closed can be made within the scope of what
35 is claimed without departing from the spirit
of the invention.
The present invention has been illustrated
in its preferred embodiment .in the accom-
panying drawing, wherein.similar reference
40 characters have been employed to denote
corresponding parts, and wherein
Figure 1 is a side elevation of the im-
proved device, parts being broken away.
Fig.. 2 is a plan view of the device in re-
45 versed position, parts being shown in sec-
tion. Fig. 3 is a fragmental detail. Fig. 4
is a perspective view of the dog or pin em-
ployed in carrying out the invention.
in carrying out the invention, reference
50 being had in detail to the drawing, there is
provided a suitable frame or supporting
structure 1, which may be mounted upon,
or which forms a part of, an ordinary welldrilling apparatus. A shaft 2 is journaled
to the frame 1 and is rotated in one direc- 55
tion, indicated by arrows on the figures, by
any suitable prime mover, the shaft being
continuously rotated during the operation
of the machine, and as the manner of actuat-
ing the shaft is of no moment, the same need 60
not be further described or illustrated in
detail.
Loosely mounted on the shaft 2 is a drum
(11 reel 3, and a disk or wheel 4 is also
loosely illminted on the shaft 2 adjoining 65
one cn(d of the drum 3, the central portion
of tho disk or wheel 4 being offset, as at 5,
to receive the respective flanged end of the
drum. A series of pintles 6 are secured to
the face of the disk 4 adjoining its periph- 70
cry, so that the disk together with the pin-
tles are in the form of a crown wheel.
Spools or pulleys 7 are mounted loosely or
rotatably upon the pintles 6 and the drill
cable or rope 8 is trained around the series 75
of spools or pulleys 7, the cable 8 being ex-
tended from one of the spools 7 to the drum
3 upon which it is wound. The spool 7 over
which the drill cable 8 is trained directly
from the drum 3 has a supplemental spool 7' 80
cooperating therewith to prevent the cable
from jumping from or working otf of the
said spool.
The11e drums 3 being disposed loosely upon
the shaft 2 may be rotated independently 85
of the rotation of the shaft, and to this end,
a counter shaft 9 is journaled to the frame
1 beyond the disk or crown wheel 4, sprocket
wheels 10 and 11 being secured to the shaft
9 and the respective end of the drum 3 and 90
having a chain 12 trained thereover. It will
thus be evident that the rotation of the
counter shaft 9 will rotate the drum 3. In
order to conveniently rotate the counter
shaft 9, the same is provided at one end 95
with a hand wheel 13, and to ordinarily
prevent the retrograde or reverse rotation
of the shaft 9, the same is provided at the
said end with a ratchet wheel 14 cooperating
with a pawl or dog 15 carried by the frame. 100
The pawl or dog 15 in engaging the ratchet
wheel 14 will prevent the drum 13 from ro-
tating in such a direction as to permit the
drill cable to unwind therefrom, but it is
evident that when the pawl 15 is released, 105
the drill cable is permitted to unwind from1,106,322..
