adapted to be secured on the axle PI, so thit
the horse-power can be readily transported by
attaching it at the rear end of the drill when
the latter is moved from place to place.
5 Q is a transverse shaft arranged to slide in
bearings IV~ M on the beams E' E', and carry-
ing a heavy fly-wheel, S, -at one end and a
pinion, T, near its other end, which pinion
meshes with the gear-wheel N. At the end of
io shaft Q' is arranged a circumferentially-
grooved disk, U, that is engaged by a semi-
circular rod, V, carried in the bifurcated end
WV' of a shifting-lever, X1, that is filcrumned
on a standard, Y", projecting from one of the
15 beams G. By operating this lever thc pinion
Tn maybe thrown into and out of engagement
with the gear-wheel N. It is, designed' to be
out of engagement when the drill is out of op-
eration and' the drums are being:wofind, but
20 should always be in operation With the drill.
This fly-wheel will secure an even and-steady
motion to the drill mechanism, and will, pre-
vent the horse from pitching forward when
the drill drops. Its more important function
25 is: to: prevent the drill from sticking after it
has dropped, as the inertia of the wheel will
lift the'drill the instantit reaches its dowmvard
limit.
Z2 is the drum on which the drill-rope Wis
30 wound. This drmui has bearings A: at one
end on one of the beams G, and has its bear-
ings at its other end in a box, B', arranged to
slide in a guide-plate, C0, arranged on the
other beam G, to bring a gear-wheel, D:', on
35 the drum into engagement with the- gear-
ieel N'when it is desired to wind the rope
W on the drum. The sliding box BP is oper-
sted by a lever, E, connected to the said box
by a pivoted rod, F. The end of the drnum-
40 shaft is provided with a friction wheel or disk,
GC, around which is arranged a flat brake-
spring, H : secured atone end, I', to the beam
G, and having its other end pivotally con-
nected, as shown at J, to an angular lever,
45 KX', that is connected by means of a pivoted
rod, L3, with a lever, 3P, by which the spring-
brake can be operated as desired. Normnially
the disk G" will be back against the spring I",
to brake the drumn as the drill-rope unwinds.
o At the'rear end of the machine is arranged
another drum, N', having one end bearing, as
at O1, on the beam G, while its other end, P',
bears in the top of a lever, I", that is ful-
erumed in a slot, Q:, in the other beam G.
55 The lever RP is operated by means of a lever,
S', and a connecting-rod, T', to shift thegear-
wheel U:' into engagement with the wheel N
when it is desired to wind up the drum. The
rope V , that carries the bucket for drawing
60o: water, is adapted to wind on this drum, from
which it passes over a pulley, W'V, in the der-
rick-frame. When it is desired to wind the
rope V uplon the drum, the latter is thrown
into engagement with the gear-wheel N, and
65 when released from this engagement a fric-
tion wheel' or disk, X:, on the shaft of the
drum will come against a brake-block, Y', onthe beam G and hold the drum so' that the de-
scent of the bucket will not be too rapid.
At the rear end of the machineis arranged a 70
transverse brake-bar, Z', carrying shoesAA',
that engage the rear wheels, E E, and pro-
vided with an arm, B1, by which the brake can
be operated. This operating-rod can be con-
nected by a removable rod, C', with the lever 75
that operates the front drill-drum, so that the
niachine will be braked in position during op-
erating by reason of the position of this lever.
The operation and advantages of my inven-
tion will be readily understood and appreci- 80o
ated. 'It is very simple and inexpensive in
construction, and can be easily and conven-
iently operated.
SIm aaware that the fixed ratchet and loose
arm carrying the iawl for operating the drill 85
are old, and I therefore do not broadly claim
this as of my invention.
I claim as my invention-
1. The combination of the rotary main shaft,
the drill-rope. mechanism on the -shaft' con- 90
necting with the' drill-rope to raise the drill,
a gear-wheel on the shaft, a shaft having a
pinion engaging- this gear-wheel, and a fly-
wheel fixed on this lattershaft, whereby stick-
ing of the- drill is obviated, - substantially as 95
set forth.
2. The combination of the frame of the mna
chine, comprising inits construction a derrick-
frame at its front end, having suitably-arranged
pulleys, a centrally-arranged main rotary op- ioo
eratingshaft, a gear-wheel fixed on the said
shaft, a winding-drum arranged in shifting
bearings at each side of the main shaft, gear-
wheels fixed on the drums and arranged to
mesh -with the gear-wheel on the main shaft, los
mechanism for-shifting'the drums, the drill-
rope arranged on the front drum, mechanism
on the main shaft connecting with the drill-
rope and adapted to operate the same, and thire
bucket-rope arranged on the rear drum, sub- iio
stantially as and for the purpose set forth.
3. The combination, with the drill-rope
drum arranged in the shifting bearings and
provided with the friction-disk, of the spring-
brake extending around the said disk and con- I 5
-nected at its free end with lever-operating
mechanism, substantially as and for the pur-
pose set forth.
4. The combination of the rotary main shaft
fixed in its bearings, and carrying mechanism 120
adapted to operatethe drill-rope, a gear-wheel
arranged on the said shaft, the drum having
its bearing in a sliding box, mechanism for
operating the sliding box, the drill-rope wound
on the said drum, a gear-wheel fixed on the 125
drum and adapted to be thrown into engage-
ment with the gear-wheel on the main shaft, a
friction-diskarranged on the shaft of the drum,
and a spring-brake engaging the said friction-
disk, substantially as and for the purpose'set 30
forth.
5. The combination of the main rotary shaft
having fixed bearings, a gear-wheel arranged
on the said -shaft, a rotary drum having its
