ELI CATLIN, OF POST OAK, TEXAS.
WELL-DRILLING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 288,975, dated November 27, 188F.
Application filed July 18,1883. (No model)To all zihvom, it c7ny concern :
Be it known that I, ELI CATLIx, a citizen
of the United States, residing at Post Oak, in
the county of Jack and State of Texas, have
5 invented a new and useful Well-Drilling Ap-
paratus, of which the following is a specifica-
tion, reference being had to the accompany-
ing drawings.
This invention relates to machines for drill-
io ing wells and the like; and its object is to pro-
vide a machine possessing superior advantages
in point of simplicity, convenience, ease of
operation, inexpensiveness, and general effi-
ciency.
15 In the drawings, Figure 1 is a perspective
view of my improved well-drilling machine in
position for operation. Fig. 2 is a top view
of the same. Fig. 3 is a front end view. Fig.
4 is a vertical transverse sectional view taken
20 through the operating-shaft. Fig. 5 is a de-
tail sectional view if the ratchet mechanism
by which the drill-shaft is operated. Fig. 6
is a detail perspectiveview of the direct mech-
anism for throwing the rear drum out of gear.
25 Figs. 7, 8, and 9 are details.
Referring to the drawings, A designates the
main supporting frame or truck, which com-
prises the front axle, B, having wheels C C,
the rear axle, D, having wheels E E, and the
30 connecting-reach F. The (drilling mechanism
is secured on this frame, and is therefore
adapted to be conveniently transported from
place to place.
G G are the longitudinal side pieces of the
35 drill-frame, these being connected at their
front ends by a bolster, H, that is united to
the front axle by the king-bolt I, and from
which project uprights J J at the sides of the
machine.
40 K is a standard about centrally arranged on
the reach F; and L is the main operating-
shaft of the machine, which has its bearings
M MIi in the said standard and on one of the
side beams, G G, and carries a main gear-
45 wheel, N. At the inner end of the shaft L is
fixed a ratchet wheel or disk, O, that is in-
closed within a plate, or arm, P, that is ar-
ranged loosely on the same end of the shaft,
and carries a pawl, Q, that is forced into en-
50 gagement with the ratchet-disk by means of
a spring, R, as shown. In the projecting arm
of the plate P are formed a series of perfora-tions, S, in any one of which the end T of a
rod, U, is adapted to be inserted. This rod
is connected by a rope, V, with the drill-rope 55
WV, which passes over a pulley, X, at the top
of the derrick-ffame Y, that comprises two
convergent uprights,. Z Z, hinged at their
lower ends to the uprights JJ, as shown at A'
A', so that they can be folded down rearwardly 6o
when the machine is not in use, and rested on
a bolster, B', arranged at the rear end of the
machine. This derrick-frame is supported,
when in upright position, by inclined braces
C C', that are removably connected to the up- 65
rights Z Z, and are likewise secured at their
rear lower ends, D' D', to horizontal beams
EB E', which are elevated above the beams G
G by uprights F F, and carry the bolster B'.
When the derrick-frameis lowered,the braces 70
C3 C' are disconnected and laid on top the ma-
chine.
In operation, when the shaft L is turned to-
ward the front of the machine, the disk 0 en-
gages the pawl Q on the arm P, and carries 75
the latter around, as shown by the arrow, Fig.
5 of the drawings, to the point designated by
G'. During this movement of arm P it of
course carries the rod U, which draws on the
drill-rope and lifts the drill. As soon as the so
arm P reaches the point G', the pawl becomes
disengaged, and will pass over the teeth of the
ratchet O as the arm P flies around and the
drill suddenly drops. The pawl Q will now
be again in engagement with the teeth of the 85
disk, and the operation will be repeated with
each revolution of the shaft L. When the
shaft I is turned in the opposite direction-
i. e., toward the rear end of the machine-
(which movement is necessary to wind the go
drums, as hereinafter specified,) the arm P
will retain its position, and the pawl Q will
slip over the teeth of the ratchet 0 as the lat-
ter revolves with the shaft.
The revolution of the shaft L can be effected 95
by any suitable power, but is preferably op-
erated by the horse-power herein shown and
specified. This horse-power-a horizontally-
anchored inverted crown-wheel, H , that is
journaled on an axle, P-carries thesweep J', ioo
and meshes with a pinion, K', on a shaft, L',
having bearings 3P i in ground-blocks N'.
A tumbling-rod, O', transmits the motion of
this shaft L' to the shaft L. Wheels P P' are
