drum is operated to pay out cable to relieve the

When the excess strain subsides, the ship tends
to move back to its original position, due to line

becomes greater than the line tension so that

To accomplish this as stated the apparatus is

For high speed operation with the motor brake

tion the brake band 14, which has been released
from brake drum 4'! for low speed operation, is
tightened by manipulation of the band wheel 81
to arrest rotation of the brake drum 41 and there
by the ring-gear 49. The sun-gear 39 driven from
the motor through gears 34, 2|’, l8 and 22 causes
the planet pinions 48 which are rotatable on the

‘
The automatic tension control may be adjusted
by moving member I84 up and down, see Fig. 4.
As said member is moved up or down it, through

‘and levers I82 and I94 shifts the pivotal con
nection of lever I94 with lever I98 and I98 so
that movement of the brake-band operates on
lever I91 according to the adjustment. - That
is, the brake-band may actuate lever I91 and
arm 238 so as to produce a greater or less motor
torque by moving arm 238 relative thereto in
such a way that it cuts out more resistance in
the motor circuit for additional torque.
Thus
the tension control vmay be adjusted so that when
a certain predetermined tension on the cable is ‘
exceeded the control mechanism is put into oper

When the apparatus is to haul the ship from
' the beach, the cable-drum is rotated in heaving

and subsequently at a higher speed with lower
line pull. To accomplish this the brake-band ‘I4

- When the’ clutch members 21 and 28 are dis
engaged as in Fig, 2, the lower end of lever I8'I
' is disposed within the U-shaped lever I88. To
throw the clutch members into engagement for >
low speed operation the lever I88 is depressed and
lever I88 is moved to the left, whereupon its
lower end I81 is disposed over the outer end part
of lever I ‘III which is urged upwardly thereagainst
by spring I "II.
When the rotation‘ of cable drum accelerates
from low‘ to high speed as aforesaid, so as to
throw clutch member 28 outwardly and thereby
- swing the lever I 81' inwardly, the said lever I81
passes from oil lever I88 which is urged upwar
by spring "I to the position shown.
‘
It may be ‘noted that with the brake-band dis
engaged from the brake-drum and the clutch
members disengaged that the cable-drum is free
for rotation by the pull of the cable while with
the cable-drum held stationary the motor and
intermediate shaft may be rotated.
The invention may be embodied in other spe
ci?c forms without departing from the essential
characteristics thereof. Hence, the present em
bodiments are therefore to be considered in all
respects merely as being illustrative and not as
‘Ring-gear 49; carried by the brake-drum‘ 41. 75 being restrictive, the scope of the invention being
