This invention pertains lbroadly :td drilling
a-pparatus, but more particularly to supporting
rigs for fluid actuated vdrills commonly known
as wagon drills.
5A
One object of this invention is to produce an
improved drilling apparatus of the wagon drill
type.
.
-
Another object of this invention is to provide
a wagon drill with a mechanism lwhereby the
1.o: drill maybe positioned -for drilling holes <in di-f
ferent positions relative »to the framev supporting
the drill, land may be >adjusted vertically 'and
longitudinally of the latter.
Another Iobject of this invention is to produce
15. a wagon drill of vsimple construction.,'constitut
ing an assembly which is strong, dura-ble and
eflicient.
Other objects and advantages more -or less an
cillary to the foregoing reside in’ the.v specific -con
20 struction and aggroupment of the elements
peculiar to this structure, as
become ap
parent from .a more ycomplete examinationl of
this specification.

~-lilxtending from -one to the other track 23, 2O
there is a tubularwcrossmember 3| having »each

posed bosses 35, `each v.having a -bolt .3.6 extending
therethrough cooperating with anut 31 .and a
clamp-38 for locking lthe cross .member 3l lagainst
movement relative to thetracks23. As shown
in Fig. 6, «the .clamp 38 is AL shaped and has one
end formed with .a .ridge ‘.39 engaging the bottom
of the'bos's 35, while the other yend is areuated 35
as at 40 in Fig. 8, .for Aengagement with the ar
cuated bottom Wall 29 of the track 23. 'I'he wall
of the .ola-mp leading from the arcuated end 40
is also in engagement with the side wall 21 of
the track ‘2.3 to. prevent the spreading of the 40
side members I9 .an'd‘2ll of the carrying frame I5.
Longitudinally Vdisposed through the tubular
cross member 3|, there is a shaft 4I having each
end-supported within a bearing '42' formed in a
_
cap 43 secured to each end of the cross mem- 45
ber by bolts 44. To each end portion of the
shaft’ 4I is vkeyed a gear or pinion 45 meshing
with thefteeth 26 -of 4the corresponding'track 23.
Intermediate its ends, the cross >member 3I is
formed with a -rtransversally disposed `boss 46, 50
having an aperture “extending therethrough
and'ada-pted to rotatably accommodate a worm
48. Each end of the aperture -41 is threaded to
receive a Anut 4'9 through’which extends the re

by which the worm may be rotated. The worm
48 is in constant operative engagement with the

member 60, which is a replica of the cross> mem
30 ber 3|, is pivotally mounted a clamp 6|, which
in turn is adapted to receive the center housing
52 of a` drill guiding frame 63. kThis housing
is mounted within the clamp 6| in a manner
permitting the pivotal movement of the drill
35 guiding frame on an axis normal to the longi
tudinal center axis of Vthe cross member 60.
Since the connection between the cross mem

a part of this invention, and that >_the construc

I-n the operation of the mechanism, when the
worm 48 is rotated through the'crank handle
45 5|, rotation is imparted'to the worm gear 52,
thus -imparting rotation to the pinions 45 through
the shaft 4|. The pinions V«l5 engaging the teeth
26 of the circular tracks 23, will cause the tubu
larcross member 3| to travel on the tracks in
50 a circular >path passing between the two side
members I9 and _28. Due to the movement of
the tubular cross member 3|, it`will be under
stood that the drill guiding frame,- together with
the drillv 55 therein, may be elevated or low
55 ered with respect to the carrying frame, and
be adjusted longitudinally of Vthe latter. ,Due to
the movement of the cross member 3|, and the
pivotal connection of the'drill guiding frame
therewith, the drill 55 may be moved in various
60 drilling positions, above or below the carrying
frame, while one end of the drill guiding frame
is movable through the open end of the carrying
frame.
.
The cross member 3| may be locked against
65 movement relative to the carrying frame in any
position possible Aby virtue of its travel on the
arcuated tracks or guides 23, by tightening the
nuts 3l cooperating with the bolts 36, for caus
ing the clamping engagement of the-arcuated
70 end wall 40 of the clamps 38 withA the bottom
wall 29 of the tracks 23.
