orally from the mast, the other end of the
lever being reeled upon the drum 15. The
operating or drive shaft now being turned
either manually, as by means of a crank-
5 handle,or by other power,such as horse-power,
the looped crank-arm 17 is brought into en-
gagement with the free eiid of the spudding-
arm to depress the latter and thereby elevate
the tools. When the free end of the spud-
1o ding-arm is released by the crank-arm, the
former returns to its elevated or normal po-
sition, where its motion is checked by a stop
consisting of a cross-bar 25, with which en-
gages a block or buffer 26 on the spudding-
15 arm. Obviously the continuous rotation of
the drive-shaft in a uniform direction will
cause the oscillation of the spudding-arm,
and consequently the reciprocation of the
drill-tool, the return of the spudding-arm to
20 its elevated position being due to the weight
of the drill-tool or other device attached to
the hoisting-cable when said cable is engaged
with the running hitch 23. As the drilling
operation proceeds the hoisting-cable may be
25 fed manually by allowing it to " pay" around
the belaying or fastening pins 24 and unreel
from the drum 15. After the solid material
in the well has been sufficiently loosened the
drill-tool should be elevated by drawing upon
30 the operating-cable 14to unreel the same from
the drum 13 and reel the hoisting-cable upon
the drum 15, said drum 15 having previously
been locked to the drive-shaft by sliding it
axially to cause the engagement of the clutch
35 members and the hoisting-cable having been
disengaged from the belaying-pins 24 and the
running hitch 23. In order that the hoist-
ing-cable may be guided positively to the
drum 15, I preferably employ a direction-pul-
40 ley 27, supported by a forwardly-extending
arm 28 of the frame. Having accomplished
the elevation of the drill-tool by the extension
of the cable 14, (the latter being accomplished
either by horse-power or otherwise, as may
45 1e preferred,) the bailing-bucket 1.2 may be
attached to the hoisting-cable and lowered
into the well under the control of the brake
21, thereby rewinding the operating-cable 14
upon its drum 13. The bucket is provided
50 in its lower end with an inwardly-opening
valve 20, and by vertically reciprocating the
bucket, as by drawing intermittently upon
the hoisting-cable to successively raise and
lower the bucket through a short interval, the
55 loosened material in the well will be drawn
into the bucket, whereupon the bucket may
be withdrawn from the well by unwinding
the operating-cable 14, as hereinbefore de-
scribed. Obviously the drilling or loosening
Go and bailing operations may be repeated as
often as may be necessary to remove the de-
sired solid material from the well.
From the foregoing description, taken in
connection with Figs. 1 and 3 of the draw-
65 ings, it is observed that in my machine I-em-
ploy a single shaft which consists of two co-
axially-disposed lengths and an intermediatecrank portion which connects the said lengths
of the shaft. This shaft serves as the means
for supporting the two cable-spools and for 70
the operation of the spudding-arm. The ca-
ble-spool around which the operating-cable
14 is coiled is made fast with one length of
this shaft. The other cable-spool 15 is fitted
loosely on the shaft to remain at rest nor- 75
mally and adapted to be shifted into engage-
ment with the crank of the shaft. The spud-
ding-arm is mounted at one end pivotally on
the frame, so as to have its other end dis-
posed in the path of the said shaft, whereby So
the single shaft may be driven by the cable
14 or a crank, and this shaft serves to impart
an oscillating or vibratory motion to the
spudding-arm and the rotary motion to the
spool on which the tool-cable is reeled. This 35
spool is provided with clutch elements 16,
adapted to be interposed in the path of the
crank for the purpose of making the spool
fast with the crank and the shaft, whereby
the crank is made to serve as an element of 9o
the clutch mechanism. With the spool 15 is
associated means for conveniently shifting
the same into and out of clutching relation
with the crank,and a brake-lever is also adapt-
ed for engagement with the spool to arrest 95
the latter. It is to be observed, f ur thermore,
that the spool may be shifted for its clutch to
free the crank of the shaft, and the lever may
be engaged with said spool to hold the latter
at rest or to allow the spool to turn idly on zoo
the shaft in order to pay out the cable 10 in
the operation of lowering the cutting-tool or
bailer into the well; but to elevate the cable,
so as to withdraw the cutting-tool or bailer
from the well, this spool should be shifted mo5
for its clutch elements to engage with the
crank, so that the spool will rotate with the
shaft. The improved construction and ar-
rangemnent of parts tend to materially simplify
and cheapen the apparatus as an entirety, and mia
all the elements thereof are arranged so as to
be conveniently and easily operated without
requiring the attendant to move from his sta-
tion at the machine.
Projecting forward from the mast adjacent 115
to the hoisting-pulley are guide-pins 30, which
are of particular use when the cable is slack
to prevent the disengagement thereof from
the pulley.
Various changes in the form, proportion, 120
and the minor details of construction may be
resorted to without departing from the spirit
or sacrificing any of the advantages of the in-
vention.
Ilaving described my invention, what I 125
claim is-
A well drilling and cleaning machine con-
prising a frame having a mast, a single shaft
provided with a crank, a power-spool,13, fast
with the shaft, a loose drum, 15, shiftably 130
fitted on the shaft and having the spaced
clutch-pins arranged for engagement with the
crank, a lever, 1, having a slidable shipper-
arm, 19, engaged loosely with the dnmn, 15,
