Original application January 29, 1936, Serial No.
61,387. Divided and this. application June 13,

‘ v 1 8 Claims.
(01. 280-3315)
The present invention relates to'improvements
in a coupling and aligning device 'andtis divisional
to my application, Serial Numberv?lg38'7, filed
January 29, 1936, on a Machine for laying: cable,
.5. pipe and the like.
In the latter application I described a cable
laying out?t comprising a tractor or otherdraft
means, a reel carrier and a cable laying machine
adapted to draw a crevice through the earth sur
face, to feed the cable into ‘the crevice, to cover
the crevice over the cable andto tamp the cover
age in a single and continuous operation.
After a complete reel has been‘ fed into the
ground in this manner it is. necessary to dis~
connect the reel carrier from. ‘the cable laying
'
’
Further objects and advantages of my inven
tion will appear as the speci?cation proceeds.
' The preferred form of my invention is illus~
trated in the accompanying drawing in which
, Figure 1 shows the cable laying out?t ‘in side
elevation.

machine, to pull the carrier‘. toward a'new reel,
While I have shown only the preferred form of
to exchange the old reel for _ a new one, to
my‘ invention I wish to have it understood that
various changes or modi?cations may be made
within the scope of the claims hereto attached
without departing from the spirit of the inven
tion. Particularly ‘I wish to have it understood
that while in the present speci?cation I have de
scribed my coupling and aligning means in con
manoeuvre the reel carrier back into operative
proximity to the cable laying machine and tore-,
couple the
same.

V In view of the heavy weights‘ involved and in
view of the fact that in field operations ‘the
ground‘ is always uneven. and difficult to work on,
the re-coupling is a dif?cult task, very time-con
25 suming and accompanied by ‘ hazards for ‘ the
operators. As a matter ‘of: fact, ini-presentt?eld
operations, much more time is usually spent in
a day's work on the re-coupling operations tha
on the actual laying of the cable. I

means for determining the intensity of the draft
required for a particular operation.
,
'
It is the principal object of the present inven
tion to provide a coupling and‘ aligning means
which allows the re-couplingkto be effected ex
peditiously and without any hazards to the oper
ators.
-
It is further proposed to provide a coupling
and aligning means which is‘power-operated or
otherwise and which may use'the power of the
tractor or other draft means for furnishing the
power required.
40 More particularly it is proposed to combine an
aligning means with the coupling means. whereby
the reel carrier and the cable laying machine are
?rst drawn toward one another and into align
ment with one another until respective “parts 'of
the reel carrier and the cable laying machine
have reached, a desired relative‘position in which
nection with a cable ‘laying out?t, 'the'principles
of the invention are not con?ned to this particué
paratus are to be coupled, particularly under
difficult conditions as are found in general ?eld
operations.

I Referring to the drawing in detail it will .be
noted that the cable laying out?t shown in Figure
1 consists of the tractor I; the reel carrier 2 and
the cable laying machine 3. The latter'has been
described in the parent application and is, only
brie?y referred to herein as comprising a frame
4, a pair of wheels 5 supporting the same rela
tive‘to the earth surface, a subsoil cleaver 6 ad
justable relative to the frame to draw a furrow
or crevice through the earth surface, a feed tube

point l0 at the rear end of the cleaver, back-?ller

the'cable has been laid and a roller l2 for tamp

The operation of my invention will be readily
understood from the foregoing description. After
the entire length of cable has been fed from a
60 reel, the reel carrier is disconnected and'pulled
bythe tractor to a place where a new’ reel may
be substituted for the empty one. The reel car
rier is then manoeuvred back into approximately
