the drum 3, the cable passing around the
spools 7 without interfering with the mo-
tion or stability of the disk or crown wheel 4.
The disk or crown wheel ' is oscillated or
5 actuated in a novel manner, as will be pres-
ently described. An arm 16 is keyed or se-
cured rigidly upon the shaft 2 adjoining the
disk 4, opposite the drum 3, the Tree end of
said arm being hollow or pocketed, and hay-
1 ing a member 17 telescoped or fitting slid-
ably thereinto. A coiled wire spring 18 is
housed within the arm 16 andl messes out-
wardly against the member 17 to normally
project the said member, the sliding moe-
g5 mont of the member 17 being limited by a
lug 19 carried thereby moving within a
slot 20 provicled in the arm 16. Ordinarily.
the lug 19 seats against the outer end of the
slot 20 to properly position the member 17
o when it is inactive. A dog or pin 21 is
engaged transversely through the outer or
free end of the member 17 and has a wheel
or roller 22 journaled upon one end thereof
the other end of the pin 21 being preferaby
25 squared or flattened. The pin 21 is secured
rigidly to the member 17 by meas oC a set
screw or other securing' member, as will be
apparent.
The pin or dog 21 is adapted to engage
so the. disk or crown wheel 4 under certain
conditions, as will hereinafter appear, the
said disk being provided with a projection
or shoulder 23 with which the respective
end of the pin 21 is adapted to engage. The
35 pin 21 and projection or shoulder 23 ordi-
narily move in curvilinear paths at different.
distances from the shaft 2., in order that
they may pass each other without coming
into engagement.
40 In order to move the pin 21 into engage-
ment with the projection or shoulder 23 of
the disk 4, an arm 24 is mounted loosely
upon the shaft 2 adjoining the arm 16, and
is provided at its free end with a cam 25
45 lying in the path of the roller or wheel 22
carried by the pin 01. The cam 25 is so
designed as to engage the roller 22 and to
force the member 17 inwardly, in order that
the pin 21 will move into the path of the
5o projection or shoulder 23 of the disk and
to hold the pin in engagement with the said
projection until the pin passes the cam 25,
in which event, the member 17 will be
thrown outwardly by the spring 18 to re-
55 lease the pin from the said projection.
In order that the cam 25 may comple-
ment or cooperate with the projection or
lug 23, a. second counter shaft 9' is jour-
naled upon the frame 1 adjoining, or
oo slightly above the counter shaft 9, the
sprocket wheels 10' and 11' being secured
to the counter shaft 9' and arm 24, respec-
tively, and having trained thereover, a
chain 12'. It will thus be obvious that the.
65 arm 24 may be rotated about the shaft 2 byactuating the counter shaft 9', the counter
shaft being provided at one end with the
hand wheel 13' for convenience in actuating
the same. The counter shaft is prevented
from rotating in a retrograde direction, due 7
to the contact of the roller 22 with the cam
25, by means of a ratchet wheel 14' secured
to the counter shaft 9' and cooperating with
a pawl or dog 15' carried by the frame.
In practice, the present device replaces 75
the ordinary walking beam and spud lever,
the present device being readily applied to
an ordinary well drilling apparatus. As
above intimated, the actuating shaft 2 is
continually rotated during the operation of so
the machine, as by means of a suitable prime
mover, or other source of power. The arm
16 being rigid with the shaft 2 will rotate
therewith, and by properly adjusting the
arm 24 through the medium of the hand 35
wheel 13', the cam 25 may be made to co-
operate with the projection 23 of the disk 4,
in order that when the pin 21 approaches
the cam 25, the member. 17 in being forced
inwardly by the cam, will cause the respec- 90
ti;e end of the pin 21 to engage the pro-
jection 23 of the disk or crown wheel, and
as a result the disk or crown wheel will be
given a slight movement or partial rotation,
the pin 21 being released from the projec- 95
tion 23 after the cam 25 is passed. Whei,
the pin is thus .released from the disk or
crown wheel, it being noted that the forced
rotation of the disk or crown wheel will
cause the drill cable 8 to wind upon the 100
wheel, so as to raise the drill within the
well, the disk or crown wheel will again be
free so that the weight of the drill will
cause it to gravitate or descend within the
well, the disk or crown wheel 4 swinging 105
back to normal position. In this manner,
the crown wheel is oscillated during each
revolution of the shaft 2, the drill rope be-
ing intermittently raised so as to properly
actuate the drill. 110
The drill may be. let clown., from time to
time, as. it works into the earth, this being
readily accomplished, by so rotating the
drum 3 that the drill cable 8 may unwind
therefrom, the pawl 15 having been released 115
Lrom the ratchet wheel 14. Particular atten-
tion is directed to the fact that the drum is
disposed within the periphery of the crown
wheel, whereby the drum in being rotated
will permit the cable to be unwound with- 120
out interfering with the reciprocation of the
cable to any appreciable extent. The feed-
ing of the drill cable 8 into the well will
not affect the operation of the crown wheel,
so that the drill cable may be fed into the 125
well simultaneously with the actuation
thereof. As the drill works into the earth,
the normal position of the projection or
shoulder 23 of the crown wheel will change,
but the operator may properly position the 1p2
