the like.
_
The rail or track 24 is provided to carry the
car 25 for lmovement between a position adjacent
the rail 21 and an out position adjacent the. rack
rail 29. The track 24 extends outwardly from
the rail 21 to the rail 29 and preferably extends
in a direction substantially radial relative to the
rotary table I2. In accordance with the broader
principles of the invention the track 24 may be
varied in construction. In the particular case
illustrated in the drawings the track 24 includes
an elongate member 33 of wood or the likeI lt 15
being understood that the main track member
may be in the natureof a steel beam. Angle
irons 34 may be provided on the upper corners
of the member 33 to have their upper flanges lie
against the upper surface of the member. 'I'he 20
inner end of the track 24 is spaced some distance

and other mechanisms. In the drawings we have
shown a suitable housing I6 for enclosing the
25 drilling engine, the pumps and other equipment.
An arm I1 projects horizontally from the upper
portion of the derrick II and' carries a sheave
or pulley block I8. A hoisting line I9 is wound
on the drum I4 and extends to the upper end of
30 the derrick II where it operates over a suitable
pulley 20 and the pulley block I8. A hook 2| 'is
provided on the hoisting line I9 and, as illus
trated in Fig. 1 of the drawings, may carry an
elevator 22. The pulley I8 is located substan
35 tially directly above the rotary table I2. The ro

The dolly car 25 is movable along the track
24 and is adapted to support or carry the ends
of the lengths of pipe P when they are being 40
racked and removed from the rack 23. The
particular car 25 illustrated in the drawings in
cludes a bottom orbody 36 of substantially rec
tangular plan elevation. The car 25 is supported
on the'track 24 and has its body 36 some distance 45
below the plane ofY the upper sides of the rack
rails 21 and 29. The outer portion of the car
body 36 may have an upwardly and outwardly
inclined surface 31. The car 25 includes side
plates 38 secured to the body 31 to project above 50
the upper surface of the body and to project a
tion and may be formed of various suitable ma

The embodiment o`f the invention illustrated in
40 Figs. 1 to 7, inclusive, of the drawings includes,
generally, a supporting structure or rack 23, a
rail or track 24 at the rack 23, a dolly or dolly
, car 25 Imovable along'the track 24 and adapted
to support an end of a length of pipe P, and
45 means 26 for returning and counterbalancing
the car 25.
The supporting structure or rack 23 is provided
to support the racked pipe P in a reclining posi'
tion when not in use in the well. In accordance
50 with the broader aspects of the invention the
terials. In the particular embodiment of the in
vention illustrated in the drawings the rack 23
55 is of simple construction and is formed of wood.
The simple rack 23 illustrated in the drawings
includes a substantially horizontal head rail 21.
The rail 21 -is arranged at the end of the derrick
floor F adjacent the rotary table I2 and is pref
60 erably parallel with the adjacent end of the der-`
rick floor. In the preferred arrangement the
rack rail 21 is some distance above the floor F
and is of substantial length. 'I'he rail 21 is pref
erably continuous and is supported by suitable
65 posts 28.
The rack 23 includes a foot rail 29
spaced a considerable distance outwardly from
the rail 21. The rail 29 extends parallel with
therail 21 and is somewhat lower than the rail
21. In practice the outer rail 29 may be sup
70 ported by suitable spaced posts 30. In accord
ance with the invention the rack rail 29 is dividedI
or parted substantially intermediate its ends to
leave a vertical gap or space 3I.. The two rack
rails 21 and 29 are preferably of substantial
75 length to carry a considerable number of lengths
V
The plates 38 are vertical and substantially par
allel and are adapted to extend downwardly to
or beyond the lower side of the track member
33. The> upper edges of the plates 38 are sub
stantially parallel with the upper surface of the
body 36. In the preferred arrangement the up
per edges of the plates 38 are spaced slightly
below the uppermost surfaces of the rails 21 and 60
29 or the upper surfaces of the rail cushions 32.
Horizontal shafts or axles 40 extend between and
are supported by the plates 38. Wheels or rollers
4I are rotatably supported on- the axles 40
through suitable anti-friction bearings 42 and
are adapted to operate on the angle irons 34 of
the track 24.
.The dolly car 25 may be provided with ends.
The forward end 43 of the car 25 is preferably
removable and is only intended for use when 70
the apparatus is employed to rack the pipe or lay
the pipe down on the rack 23. 'I'he car end 43
is adapted to fit between the side plates 38. The
`forward portion of the car body 36 may be thick
ened to carry horizontally projecting bolts or pins 'I5
2,118,910
u. 'me end u is shaped-to at about' the ror
ward end portion of the body 35 and is bifur
cated having slots 45 for receiving the pins 44. '
The cooperation of the slots 45 with the pins 44
removably retains the end 43 in its proper` posi
tion on the car 25. yThe end\43 preferably pro
jects some distance above the inclined piane of the
10
upper surfaces of the cushions 32 on the‘rails 21
and 29. The car 25 may be provided with an
outer end 45 similar to the end 43. 'I'he end 45
may be permanently secured ~to the car 25 or
may be removably connected with the carin the
same manner as the end 43.
When the car 25
is on the outer portion of the track 24 and is
supporting the lower end of a length of pipe P
which is to be laid down on the rack 23 the pipe
may engage the upper edge of the inner Acar end
43 and following the disconnection-of the ele
vator 22 from the pipe the pipe may be readily
rolled from the end 43 onto the rack 23. When
the apparatus is being employed to swing the
lengths of pipe into the derrick for the purpose
of making up a drilling string or thelike, the
3 .
be easily moved along the track 24 and will re
main in any position to which it is moved.
The racking apparatus Just described may be
readily erected or installed in the derrick for
use in racking the pipe andcther objects handled 5
in the well. In practice the pipe, tubing, etc.
delivered to the -well may be delivered directly
on lthe rack 23, It will be noted vthat the rack
23 is operable to support the pipe P in a reclin
ing position in amanner so that it may be readily
rolled along the rails 21 and 23. The pipe car
ried by the rack 23 does not interfere with oper
ations at the well but is conveniently accessible.
When'it» is desired to remove a length of pipe
P from the rack 23 ‘for the purpose of assembling
it in a string at the well the >car 25 is moved along'
the track 24 to a position at the lower end- por
tion- of the track. The length oi' pipe to be
handled is preferably previously rolled along the
rack '23 to a position opposite the outer end of 20
‘the said length of pipe P. In practice an oper
ator may be stationed at the inner end of the `
end 43 is preferably removed from the car 25
track 24 and may merely push the car 25 down
wardly on the track 24 and stop it in a position
25 whereby the sections of- pipe P maybe readily
opposite the outer end of the length of pipe by
rolled onto the car 25.
-
The means 28 is provided to return the car
25 from its lower or outer position to a position
at the inner end of the track 24 following the
30 racking of each length of pipe P. The means
26 is also operable to counterbalance‘the car 25
when the apparatus is employed to facilitate the
swinging of the pipe into the derrick Il for the
purpose of making up the string. When em
35 ployed for this purpose the means 28 counter
balances the car 25 to the extent that it may be
shoved or moved along the track 24 to the de
sired position and so that the car will remain
in any position to which it is moved. The means
engaging` the line 41 adjacent the pulley- 55 or
the pulley 52.` As described above, the counter
balances 52 may be such that the car 25 may be
shifted> along the track 24 and will remain in any
selected position. Following the positioning of 30
the car 25 the operator merely rolls the selected
pipe P so that its lower or outer portion falls
into the space .3| and is received in the car 25.
It lwill be observed that the head rail 21 of the
rack 23 is continuous so that there is no danger
or the pipe 41 bodily famng from the rack; As
described above. the end 43_cf the car 25 is prei'

brackets 49 on the lower edges of the car plates apparatus is then operated to bring the ele
38 and' an end of the cable 41 may be secured
to the rod 48. The rod 48 may serve to prevent
45 the car 25 from jumping from the track 24. A
pulley 50 is rotatably supported by a suitable
bracket 5I on one of the posts 28 and-the line
so
41 operates over the pulley- 50 to‘exte'nd down
wardly to the under side of the ñoor F. _Spaced
pulleys 52 are rotatably supported under the
ñoor 41"* to direct the line >41. An arm 53 pro
jects from the upper portion of the derrick i i and
carries a suitable pulley 59. 'I'he line 41 ex
tends upwardly from one of the pulleys 52 to pass
55 through the derrick Ii and engage over a pulley
6i at the upper end of the derrick. The line
41 extends fromthe pulley 5I to pass downwardly
over the pulley 59;
.
Counterweights 52 are carried on the depend
ing end portion 'of the line 41. When the appa
ratus is being employed to rack the pipe P or
to lay the pipe down on the rack 23, the weights
vatorV 25 to a position where it may be engaged
with the inner end portion of the pipe P. When
the elevator 22 has been properly positioned 45
about the pipe P to engage the collar C' at its
end, the hoisting mechanism is operated to raise
vthe inner end of the pipe P through the medium
of the elevator 22. As the, inner end of the pipe
P is being raised ‘by the elevator 22 the outer 50
end of the pipe is supported by the car 25 which
moves inwardly along the track 24. The weight
of the outer portion of the pipe P is such that it
assures the positive inward and upward move
ment of the car 25 along the track 24. The inner 55
end of the pipe P may be raised by the elevator- '
22 until it assumes a substantially vertical posi
tion such as shown in Fig. 1 of the drawings,
at which time the car 25 is at the inner end «
of the track 24. 'I'he operator or operators then 60
swing the lower end of the pipe P from the car
25 to the position above the rotary table' |_2 for -
connection’with the string. The operator at the
62 are suchthat they operate to automatically . inner end of the track 24 may then push the

portion of the track 24 to a position at the inner it at the selected position by engaging the line
end of the track following the rolling of the pipe 41 so that the car is opposite the outer end oi’
P from the car. The weights 52 are` individually thc length of pipe P which is to _be handledat
removable from the line 41 so that the car' 25
70 may be made to operate in the desired manner.
When the apparatus is being employed to facili
tate the swinging of the pipe P toa vertical po
sition for the purpose of-making up a string, the
counterbalances 62 are preferably such that they
75 fully counterbalance the car 25 whereby itmay
the subsequent operation. 'I‘he above described
operation may be repeated to individually re 70
move the pipe P from the rack 23 and assemble
it in the string at the derrick.
When the device or apparatus is `to _be em

clining position, the rack including a head rail,l
and a foot rail in spaced substantially parallel
25 so that it will automatically move upwardly . relation to the head rail, the foot rail being inter
and inwardly along the track 24. In accordance
rupted between its ends leaving a gap, a track
with'the usual practice the elevator 25 is en
below the planes, of the rails extending from ad
jacent the head rail to a point beyond the foot
gaged with thecollar C at the upper end of the
uppermost length of pipe P and when the pipe
rail, the track passing below said gap, and a car
P is disconnected from the string its lower end ` for carrying an end of -a pipe and operable along
10 is swung outwardly to the car 25.
'I'he lower
end of the pipe P may be allowed to rest on the
body 36 of the car and the inclined surface 31
may resist outward displacement of. the lower
_endof the pipe from the car. The hoisting
15 mechanism of the rig is then operated to allow
the pipe P to move downwardly whereupon the
car 25 moves outwardly on the track 24. 'I'he
car 25 moves outwardly on the track 24 until
the pipe P assumes a position where it engages
20 the inner rail or head rail 21 of the rack 23. The
elevator 22 is then disconnected from the pipe
P and the pipe is rolled from the upper edge
of the car end 43 onto the rail 28 and is then
rolled along the rack 23 to the _desired position.
The counterbalance 62 automatically returns the
car 25 to its position at the inner end of the rack
24 and the operation may be repeated.
Fig. 8 of the drawings illustrates the invention
embodying means for positively operating and
controlling the car 25. The rack 23 of the ap
paratus illustrated in Fig. 8 of the drawings may
be identical with the rack described above except
th'at its rails 21 and 29 may be in the same hori
zontal plane to support the pipe P in a horizontal
position. The car 25 may be identical with the
above described car 25. The means for operating
' the car includes a line 10 secured or flxèd to the
car 25'. In practice the line 10 m'ay be secured to
the under side of the car 25 to extend along under
40 the track 24. Pulleys 1I are rotatably supported
by suitable brackets 12 on the posts 28 and 35
and the line 10 operates over the pulleys. A re
mote controlled motor or reversible motor 13 is
suitably located at the rack 23.
The line 10 is
. preferably continuous to operate over a pulley 14
driven by the motor 13 whereby the line 10 and
the car 25 are operated by the motor. The con
trol 15 for the reversible motor 13 is connected
in the control line 16 of the motor and may be
50 located at any suitable or convenient point. The
control 15 includes buttons 18 or control parts
for effecting the operation of the motor 13 in
either direction and the stopping of the motor.
The control 15 may be manipulated to effect the
55 operation of the car 25 in either direction and to
effect the stopping of the car 25 in any position.
The operation of the apparatus illustrated in
Fig. 8 of the drawings is substantially- the same
as that of the previously described form of the
60 invention. The car 25 for carrying the lower end
of the pipe P may be easily and accurately con
trolled by means of the control 15 of the reversible
motor. The control 15 may be positioned so that
the track and movable through said gap, the car
being movable between a position where said pipe
is reclining at the rack and a position where the
said pipe is substantially upright with its upper
end ehgaged by the hoist mechanism of the der
rick.
