PROVISIONAL SPECIFICATION.
Improvements in Log Lines and Means for Working them.
I WILLIAM PELHAM BULLIVANT of 72 Mark Lane in the City of London,
Wire Rope Manufacturer do hereby declare the nature of my invention to be as
follows
My invention relates to log lines and simple and efficient means for working
them by which the lines can be worked with great facility and convenience.
I prefer to use as the line a small flexible steel wire cord or line made of steel
wire strands and I coil it upon a reel fitted with a brake (which may be worked by
hand or foot) and provided with a handle, or handles, or equivalent device, for
rotating it. I also provide an arrangement by means of which the reel can be
thrown into, or out of, gear with the handle, or handles or equivalent device, so as
to allow the line to run out without the handle, or handles or like device rotating
with the reel. This may be effected by means of a clutch which is provided with
means for putting it into and out of gear. This clutch may also be worked by
hand or foot.
When the log line is running out it can readily be controlled by means of the
brake, and, when it is to be wound in, the reel is, by means of the clutch, connected
with the handle, or handles or like device.
I may also provide an arrangement, by which I register the length of line which
has run out from the reel.

COMPLETE SPECIFICATION.
Improvements in Log Lines and Means for Working them.
I, WILLIAM PELHAM BULLIVANT of 72 Mark Lane in the City of London,
Wire Rope Manufacturer do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
'
My invention relates to log lines and simple and efficient means for working
them by which the lines can be worked with great facility and convenience.
I prefer to use as the line a small flexible steel wire cord or line made of steel
wire strands and I coil it upon a reel fitted with a brake (which may be worked
by hand or foot) and provided with a handle, or handles, or equivalent device, for
rotating it. I also provide an arrangement by means of which the reel can be
thrown into, or out of, gear with the handle, or handles, or equivalent device, so as
to allow the line to run out without the handle, or handles, or like device, rotating
with the reel. This may be effected by means of a clutch which is provided with
means for putting it into and out of gear. This clutch may also be worked by
hand or foot.
When the log line is running out it can readily be controlled by means of the
brake, and, when it is to be wound in, the reel is, by means of the clutch, connected
with the handle, or handles, or like device.
I may also provide an arrangement by which I register the length of line which
has run out from the reel.

page_text: Figure 1 of the accompanying drawings is a front elevation of an apparatus
constructed according to my invention for working log lines and Figures 2 and 3
are views of the opposite ends of the same.
The frame of the apparatus consists of two end standards A A' connected
together by longitudinal bars a. In bearings on top of the standards A A' is
fitted to turn a shaft or spindle e having loosely mounted thereon a reel Bon which
the log line C is wound. The log line is preferably made of strands of thin
flexible steel wire. The shaft or spindle is provided with a handle 1 at each end
for convenience of turning by hand but it may be provided with gearing if it is
required to be worked by steam or other power. The reel B may be connected to
the shaft or spindle, when it is required to be rotated, by means of a clutch E one
part of which is on one end of the reel B and the other part is free to slide
longitudinally on a rib or feather on the shaft or spindle and is provided with a
groove in which the forked end of a lever G centred to a bracket on the
standard engages. Fitted to or formed on the opposite end of the reel B is a
strap pulley round which passes a steel friction strap F connected at ito a
lever centred at to a bracket on the standard A. When the line is to be run
out the clutch lever G is moved so as to slide the part of the clutch along the
shaft out of engagement with the part whereupon the reel 13 will be free to
turn on the shaft without turning the handles D. The speed of rotation of the
reel may be governed as required by means of the lever I so as to cause the strap F
to grip more or less tightly the pulley F. When the line is to be wound onto the
reel the lever I is released so as to remove the friction of the strap F from the
pulley and the lever G is moved so as to cause the part of the clutch E to
engage the part e then by turning the handles D the reel will also turn and so wind
up the line. If desired the reel may be made to gear with any suitable device to
indicate the length of line run out.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination of parts constituting the apparatus for working log lines
whether used in combination with indicating apparatus or not substantially as
hereinbefore described.
2. A log line made of thin flexible steel wire strands.
