I GEORGE WILSON HEATH, of 28 Fenchurch Street, in the City of London,
Nautical Instrument Maker do hereby declare the nature of this invention to be as
follows:-
In order to reduce the end or pull friction between the rotating parts of the log
either at the bearing in the tafrail register or of the rotator of a towing log I interpose
a series of cone rollers which fill the space between two correspondingly coned flanges
and are free to revolve against the same, a spring being interposed between the upper
bearing flange and a shoulder on the spindle. I prefer to make these rollers and
flanges of hardened steel. I provide an oiling hole and stop screw on the tafrail
register casing, and I also provide one or more oiling holes on the winged casing of
the register part of the log, which holes are normally covered by the said casing. The
bezel holding the front glass of the tafrail register is pivoted at one side and has a
notch in the edge which comes against a stop on the casing. The latter is provided
with a spring bolt, and the bezel with a corresponding hole or notch into which the
bolt is shot by the spring, a key hole being provided in the casing for inserting a key
for turning back the bolt in order to open the bezel. The rotating spindle is connected
with the line leading to the rotator by means of a cap sleeve instead of a hook as
heretofore. This cap sleeve is held on to the spindle by a spring or other catch. The
cap sleeve has a hole in the outer end through which I pass the line with a knot at
the inner end. Or I may form the rotating spindle with a sleeve and form the cap for
holding the line with a spindle working in the said sleeve. I prefer to interpose
between the rotating spindle and the line leading to the rotator what I call a regulator
consisting of three lines which may suitably be fastened by knotted ends to the cap
sleeve and I unite these three lines to a light ring (or to the ordinary cross bar). This
ring may suitably be of cane. These lines are beyond the ring united into a loop to
which the log line is connected. The log line I prefer to make with strands some one
or all of which have copper or other wire core, thus ensuring strength and lightness.
I make the rotator for the tafrail log and the register part of the towing log with a
Pri 81

The balancing wings on the log casing I arrange on each side of the aperture through
which the index is visible instead at the rear of it as heretofore, whereby I gain the
advantage of greater freedom to the rotator in its action. The rotator instead of
being provided at its inner end with a spindle or gudgeon which has its bearing in the
stationary body of the log I mount so as to turn freely on a loose sleeve which is loose
and free to turn on a hollow spindle, the inner end of which is centred and fixed in any
suitable manner in or on the end of the stationary body of the log. I thus give the
rotator a far better supporting bearing than heretofore. The revolving motion of the
rotator is communicated to the train of wheels in the body or casing by means of a
rod passing through the aforesaid hollow spindle, and provided with carrier arrange-
ment at each end to gear with corresponding carrier gear on the rotator and train of
wheels. Or instead of the rod passing (by preference_loosely) through the hollow
spindle I might transmit the motion by wheel gear. In order to give buoyancy to
the rear end of the rotator, either for the tafrail logs or towing logs, 1 prefer to form
them with an interior air chamber and to close the rear end of same with a hollow
cone. By this means the rotator tends to keep well immersed.

I, GEORGE WILSON HEATH of 28 Fenchurch Street in the City of London
Nautical Instrument Maker 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 :-
These improvements are applicable to taffrail registering logs and towing logs and
refer to means for reducing the end or pull friction between the rotating and stationary
parts, to means for facilitating and improving the lubrication of the revolving parts,
to improvements relating to the taffrail log indicator dial, to the means of connection
between the line and the taffrail register and rotator and the connection between the
line and the towing log, and to the construction generally of the towing log.
In order that this invention may be fully understood I will now describe the same
with reference to the accompanying drawings.
Figure 1 is a part sectional plan of a towing log of my improved construction and
Figure a plan of same; Figures 3, 4 and 5 are detail views. Figure 6 is a part
sectional plan of a modification of my towing log and Figure 7 an end view of an
interior antifriction roller part.
In order to reduce the end or pull friction between the rotator part A Figs. 1 to 5
and the stationary or register part B I interpose a series of antifriction bails e; these
work between the end wall a of the rotator part and the end wall or flange 6 of the
stationary or register part B. The flange b is by screws united to the hollow
cylindrical part b¹. 6 is the usual outer casing to which the balancing wings are
attached and which serves to cover up the dial. The end wall or flange bis by
preference of hardened steel against which the balls e work; these latter are by
preference of hard steel and work freely in holes formed in a ring which itself is also
free to revolve, see the end view Figure 5; the balls on the opposite side work against
a ring g which is by preference of hard steel and is loosely inserted between the balls
and the aforesaid flange a of the rotator part.
In Figure 6 I have shown a series of cone rollers e for the same object as the
aforesaid balls e. These cone rollers e as shown in the end view Figure 7 fill the
space between the correspondingly coned flanges 6 and 9 and are free to revolve
between the same. A spring may be interposed between the flange g and the flange a
on the spindle h. The flanges and g may be left loose and free to revolve in their
places.
I provide one or more oiling holes Figure 2 in the winged casing b² which
normally covers corresponding oiling holes in the hollow cylindrical part 61; by this
means I facilitate the oiling of the interior working parts.
I make the register part B of the towing log with a screwed-on ferrule k, Figues 1, 2
and 6, and shown in section in Figure 4; through the ferrule the knotted end of the
line or loop is passed; the interior conical part of the ferrule may have one or more
shallow ribs for giving a firmer hold. Or the end of the line may, as I prefer it, be
fixed as hereinafter described with reference to Figure 12. I lay no claim to passing
in the unknotted end of a line and then bring that end out through a lateral hole in
the wall of the knot chamber knotting the line and drawing the knot again snugly
into chamber through the side hole according to the arrangement described for a like
purpose in the specification of Thomas Ferdinand Walker in the specification of Letters
Patent No. 6369 dated 15th April 1884.

page_text: The balancing wings c on the casing 63 I arrange on each side of the aperture
through which the index is visible instead of at the rear of it as heretofore, whereby
I gain the advantage of greater freedom to the rotator in its action, and prevent them
from being fouled or choked with seaweed or other matters.
The rotator, instead of being provided at its inner end with a spindle or gudgeon
which has its bearing in the stationary body B of the log, I mount so as to turn freely
on a loose sleeve m which is loose and free to turn on a hollow spindle n, the inner
end of which is centred and fixed in any suitable manner in or on the end of the
stationary body B of the log; as here shown the hollow spindle n is fixed in a disc 63
which by screws is united to the cylindrical part b¹. I thus give the rotator a far
better supporting bearing than heretofore, its hollow spindle / revolving by preference
on or with an intermediate loose sleeve m which again revolves on or with the spindle n
of the stationary body B or the spindle may revolve directly on spindle n. The
revolving motion of the rotator is communicated to the train of wheels in the body or
casing by means of a rod o, Figure 1, shown also in perspective at Figure 3. This
rod o passes through the aforesaid hollow spindle n and is provided with carrier.
arrangement at each end, such as the carrier at one end and the carrier pegs p¹ pl
at the other end, to gear with corresponding carrier gear on the rotator (and train of
wheels) viz. carrier pegs on the rear end of the rotator and a carrier on the wheel
train spindle 1. Or instead of the rod o passing freely through the hollow spindle n
I may, as shown in Figure 6, transmit the motion by wheel gear. The spindle n,
which may be hollow or solid, is in that case also fixed in a disc which by screws is
united to the cylindrical part 6' of the register part of the log. On this spindle the
boss or nave h of the rotator revolves. On the boss is fixed a toothed wheel p',
which gears with a pinion g on a spindler, that enters the register gear part and has
fixed on it an endless screw, from which motion is transmitted to the dial hands in
any suitable or well known manner, but I make no separate claim to the method of
arranging the parts for supporting the rotary tube and the rod for conveying the
motion of the rotator to the registering wheelwork described and shown by John
Edward Massey in the specification of Letters Patent granted to him dated October 9,
1884, No. 13366.
In order to give buoyancy to the rear end of the rotator I prefer to form same with
an interior air chamber and to close the rear end of same with a hollow plug which
may be conical or otherwise; as shewn here the hollow cones is screwed on to the
hollow rear end of the rotator. By this means the rotator tends to keep well
immersed, but I make no separate claim to such mode of construction.
Figure 8 is a vertical longitudinal section of my improved taffrail register part with
the regulator or means. for connecting to the line leading to the rotator. Figure 9 is
an end view showing the dial and bezel, and Figure 10 a plan of the register part.
Figure 11 is an end view of the regulator. Figure 12 is a plan section through the
rotator. Fig. 13 shows a convenient form of regulator with the ordinary hook for
connecting with a tafrail register.
In order to reduce the end pull friction between the flange on the bearing a for the
spindle and the shoulder a on the spindle I interpose a series of antifriction
balls e; these work between the loose flanges or rings band g which as well as the
balls e are by preference made of hardened steel. The balls work freely in holes in a
ring which is or may be free to revolve in its place as already described with
reference to Figures 1 and 5. Or instead of the balls I may use cone rollers as
described with reference to Figures 6 and 7. The shoulder or flange a is connected
to the spindle h by means of a peg a¹ which enters a longitudinal groove in the
spindle.
I am aware that antifriction ball or roller bearing parts have been proposed
or employed for reducing friction between the parts of ship logs and described and
shown in the specification of Letters Patent granted to John Edward Massey No. 3412
dated August 30, 1876 and therefore broadly I make no claim to their use apart from
the particular arrangements or combinations of parts set forth.
I provide an oiling hole j in the top of a small chamber on the top of the register

page_text: casing, and provide a lid 62 with a corresponding small hole; this lid may suitably
turn on a central (or other) pivot and have a stop in the form of a small screw the
lower shank of which works in a curved slot for limiting the opening and closing
movements of the lid b. is a small pipe for leading the oil down to the interior of
the casing. This pipe should only be large enough to allow a drop of oil to be thrown
down therefrom occasionally by the shaking of the apparatus while at work. The end
wall u of the casing being carried toward the centre as shown prevents the oil from
being carried into the registering and dial part of the casing. The oil may thus even
fill the lower part of the casing without escaping towards that part of the casing
and clog up the gear and discolour the dial. This latter may if desired be made
luminous by means of luminous paint or composition so that the indications may be
visible by night, but I do not claim such an application as my invention. The bezel u²
or framing for the glass front or cover to protect the dial and hands is pivoted at one
side around a pivot u¹, and has a notch o¹ in the edge which comes against a stop o
on the casing. The latter is provided with a spring bolt and the bezel with a corre-
sponding hole into which the bolt such for instance as the bolt a is shot by a spring y,
a keyhole being provided in the casing for inserting a key = for turning back the bolt
in order to open the bezel. The latter may as shown in the front view Figure 14
have a face which is opaque or of darkened glass except at one or two openings
through which the indications on the dial are visible, such dial, (or dials) being
rotated by the register gear wheels. A hair line or bar is provided vertically across
each opening as shown at ', if desired.
I
The rotating spindle is connected with the line leading to the rotator by means of
a cap or sleeve 1 instead of a hook as heretofore. This cap sleeve is held on to
the spindle by a spring or other catch such as the spring catch 2 which on being
depressed permits detachment of the parts. The cap sleeve has a hole in its outer end
through which I pass the line, the latter having a knot at its inner end. Or vice versa
may form the rotating spindle with a sleeve and form the cap fc: holding the line
with a spindle working in the said sleeve. I prefer as here shown to interpose,
between the rotating spindle h with cap 1 and the line leading to the rotator, what
I call a regulator consisting of two or more lines, three lines being shewn here,
which by knotted ends or otherwise are fastened to the cap sleeve 1, and I unite these
three lines on a ring or triangle 4 made, say, of three bars, see end view Figure 11.
These lines 3 are beyond the ring or triangle 4 united into a loop to which the log line
is connected.
The log line for both kinds of log I prefer to make with strands some or all of
which have copper or other suitable wire core, thus ensuring strength and lightness.
Figure 12 shows the rotator for a taffrail log. As in the case of the towing log the
knotted end of the line or loop may be passed through a screwed-on cone ferrule such
as k, Figures 1, 2 and 6, or as shown in Figure 12, and as I prefer it, I enter the line
by a lateral hole k¹, and, having formed a knot on the end of the line, I pull the knot
into the interior cone socket. The rear end of the rotator is formed with an air
chambers in order to give buoyancy as already explained with reference to the towing
log rotator.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that I make no claim to
any portion of the inventions contained in the specifications of Letters Patent
granted to John Edward. Massey numbered and dated respectively 3412 Aug. 30 1876
and 13,366 Oct. 9 1884, or either of same, or to any invention contained in the
specifications of Letters Patent of Thomas Ferdinand Walker numbered and dated
respectively 4369 October 30th 1878 and 6369 April 15th 1884, but what I claim
is:-
First: The means for lubricating the interior working parts of a towing log and
of the register of a taffrail log, as described and shown.
Second-The combination or arrangement and use of parts of apparatus for
diminishing the end or pull friction between the rotator and the register part of

page_text: a towing log, and between the rotating line connection at the taffrail register and
the end part or cover of the taffrail register box, as described and shown.
Third: The combinations or arrangements and use of apparatus for connecting the
line to the fore end of a towing log, and for connecting the line to the taffrail register,
as described and shewn.
Fourth-The combinations or arrangements and use of parts for supporting the
towing log rotator, and for communicating the motion from the towing log rotator to
the register as described and shown.
Fifth The arrangement and use of the balancing wings of the towing log
relatively to the index aperture in the case thereof as described for the purpose
set forth.
Sixth-The improvements relating to the taffrail register dial and especially the
application of a locked bezel to tafrail register dials substantially as described and
shewn.

73:-
order to reduce the end or pull friction between the rotating parts of the log
er at the bearing in the tafrail register or of the rotator of a towing log I interpose
eries of cone rollers which fill the space between two correspondingly coned flanges
are free to revolve against the same, a spring being interposed between the upper
aring flange and a shoulder on the spindle. I prefer to make these rollers and flanges
hardened steel. I provide an oiling hole and stop screw on the tafrail register
sing, and I also provide one or more oiling holes on the winged casing of the
egister part of the log, which holes are normally covered by the said casing. The
ezel holding the front glass of the tafrail register is pivoted at one side and has a
'ch in the edge which comes against a stop on the casing. The latter is provided
a spring bolt, and the bezel with a corresponding hole or notch into which the
is shot by the spring, a key hole being provided in the casing for inserting a key
turning back the bolt in order to open the bezel. The rotating spindle is connected
with the line leading to the rotator by means of a cap sleeve instead of a hook as
heretofore. This cap sleeve is held on to the spindle by a spring or other catch. The
cap sleeve has a hole in the outer end through which I pass the line with a knot at the
inner end. Or I may form the rotating spindle with a sleeve and form the cap for
holding the line with a spindle working in the said sleeve. I prefer to interpose
between the rotating spindle and the line leading to the rotator what I call a regulator
consisting of three lines which may suitably be fastened by knotted ends to the cap

I make the rotator for the tafrail log and the register part of the towing log with a

The balancing wings on the log casing I arrange on each side of the aperture through
which the index is visible instead of at the rear of it as heretofore, whereby I gain the

spindle I might transmit the motion by wheel gear. In order to give buoyancy to
the rear end of the rotator, either for the tafrail logs or towing logs, I prefer to form
them with an interior air chamber and to close the rear end of same with a hollow
cone. By this means the rotator tends to keep well immersed.

page_text: I, GEORGE WILSON HEATH of 28 Fenchurch Street in the City of London
Nautical Instrument Maker 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 :-
These improvements are applicable to taffrail registering logs and towing logs and
refer to means for reducing the end. or pull friction between the rotating and stationary
parts, to means for facilitating and improving the lubrication of the revolving parts,
to improvements relating to the taffrail log indicator dial, to the means of connection
between the line and the taffrail register and rotator and the connection between the
line and the towing log, to the construction of the line itself, to the mode of supporting
the rotator of the towing log, and to the construction generally of the towing log and
of the rotator of the taffrail log.
In order that this invention may be fully understood I will now describe the same
with reference to the accompanying drawings.
Figure 1 is a part sectional plan of a towing log of my improved construction and
Figure a plan of same; Figures 3, 4 and 5 are detail views. Figure 6 is a part
sectional plan of a modification of my towing log and Figure 7 an end view of an
interior antifriction roller part.
In order to reduce the end or pull friction between the rotator part A Figs. 1 to 5
and the stationary or register part B I interpose a series of antifriction balls e; these
work between the end wall a of the rotator part and the end wall or flange b of the
stationary or register part B. The flange b is by screws united to the hollow
cylindrical part b¹. 1,2 is the usual outer casing to which the balancing wings are
attached and which serves to cover up the dial. The end wall or flange b is by
preference of hardened, steel against which the ballse work; these latter are by
preference of hard steel and work freely in holes formed in a ring f which itself is also
free to revolve, see the end view Figure 5; the balls on the opposite side work against
a ring g which is by preference of hard steel and is loosely inserted between the balls
and the aforesaid flange a of the rotator part.
In Figure 6 I have shown a series of cone rollers e for the same object as the
aforesaid balls e. These cone rollers e as shown in the end view Figure 7 fill the
space between the correspondingly coned flanges b and g and are free to revolve
between the same. A spring may be interposed between the flange g and the flange a
on the spindle h. The flanges b and g may be left loose and free to revolve in their
places.
I provide one or more oiling holes Figure 2 in the winged casing b³ which
normally covers corresponding oiling holes in the hollow cylindrical part 6'; by this
means I facilitate the oiling of the interior working parts.
I make the register part B of the towing log with a screwed-on ferrule k, Figures 1, 2

page_text: and 6, and shown in section in Figure 4; through the ferrule the knotted end of the
line or loop is passed; the interior conical part of the ferrule may have one or more
shallow ribs for giving a firmer hold. Or the end of the line may, as I prefer it, be
fixed as hereinafter described with reference to Figure 12.
The balancing wings c on the casing 62 I arrange on each side of the aperture
through which the index is visible instead of at the rear of it as heretofore, whereby
I gain the advantage of greater freedom to the rotator in its action, and prevent them
from being fouled or choked with seaweed or other matters.
72
The rotator, instead of being provided at its inner end with a spindle or gudgeon
which has its bearing in the stationary body B of the log, I mount so as to turn freely
on a loose sleeve m which is loose and free to turn on a hollow spindle n, the inner
end of which is centred and fixed in any suitable manner in or on the end of the
stationary body B of the log; as here shown the hollow spindle n is fixed in a disc b³
which by screws is united to the cylindrical part 6'. 1 thus give the rotator a far
better supporting bearing than heretofore, its hollow spindle / revolving by preference
on or with an intermediate loose sleeve m which again revolves on or with the spindle
of the stationary body B or the spindle h may revolve directly on spindle n. The
revolving motion of the rotator is communicated to the train of wheels in the body or
casing by means of a rod o, Figure 1, shown also in perspective at Figure 3. This
rodo passes through the aforesaid hollow spindle n and is provided with carrier
arrangement at each end, such as the carrier at one end and the carrier pegs pl p¹
at the other end, to gear with corresponding carrier gear on the rotator (and train of
wheels) viz. carrier pegs on the rear end of the rotator and a carrier 9 on the wheel
train spindler. Or instead of the rod o passing freely through the hollow spindle n
may, as shown in Figure 6, transmit the motion by wheel gear. The spindle »,
which may be hollow or solid, is in that case also fixed in a disc 63 which by screws is
united to the cylindrical part 1 of the register part of the log. On this spindle the
boss or nave of the rotator revolves. On the boss his fixed a toothed wheel p',
which gears with a pinion g on a spindle r, that enters the register gear part and has
fixed on it an endless screw, from which motion is transmitted to the dial hands in
any suitable or well known manner.
I
In order to give buoyancy to the rear end of the rotator I prefer to form same with
an interior air chamber and to close the rear end of same with a hollow plug which
may be conical or otherwise as shewn here the hollow cone s is screwed on to the
hollow rear end of the rotator. By this means the rotator tends to keep well
immersed.
Figure 8 is a vertical longitudinal section of my improved taffrail register part with
the regulator or means for connecting to the line leading to the rotator. Figure 9 is
an end view showing the dial and bezel, and Figure 10 a plan of the register part.
Figure 11 is an end view of the regulator. Figure 12 is a plan section through the
rotator. Fig. 13 shows my regulator with the ordinary hook for connecting with a
tafrail register.
In order to reduce the end pull friction between the flange on the bearing n for the
spindle and the shoulder a on the spindle I interpose a series of antifriction
balls ; these work between the loose flanges or rings and y which as well as the
balls e are by preference made of hardened steel. The balls work freely in holes in a
ring which is or may be free to revolve in its place as already described with
reference to Figures 1 and 5. Or instead of the balls I may use cone rollers as
described with reference to Figures 6 and 7. The shoulder or flange a is connected
to the spindle by means of a peg a' which enters a longitudinal groove in the
spindle.
I provide an oiling hole j in the top of a small chamber on the top of the register
casing, and provide a lid 62 with a corresponding small hole; this lid may suitably
turn on a central (or other) pivot and have a stop t in the form of a small screw the
lower shank of which works in a curved slot for limiting the opening and closing
movements of the lid 62. is a small pipe for leading the oil down to the interior of
the casing. This pipe should only be large enough to allow a drop of oil to be thrown

comes against a stop o' on the casing. The latter is provided with a spring bolt
and the bezel with a corresponding hole into which the bolt such for instance as
the bolt is shot by a spring y, a keyhole being provided in the casing for inserting a
key for turning back the bolt in order to open the bezel. The latter may as shown
in the front view Figure 14 have a face which is opaque or of darkened glass except
at one or two openings through which the indications on the dial are visible, such
dial, (or dials) being rotated by the register gear wheels.

The rotating spindle is connected with the line leading to the rotator by means of
a cap or sleeve 1 instead of a hook as heretofore. This cap sleeve is held on to
the spindle by a spring or other catch such as the spring catch 2 which on being
depressed permits detachment of the parts. The cap sleeve has a hole in its outer end
through which I pass the line, the latter having a knot at its inner end. Or vice versa
I may form the rotating spindle h with a sleeve and form the cap for holding the line
with a spindle working in the said sleeve. I prefer as here shown to interpose,
between the rotating spindle h with cap 1 and the line leading to the rotator, what
I call a regulator consisting of two or more lines, three lines 3 being shewn here,
which by knotted ends or otherwise are fastened to the cap sleeve 1, and I unite these
three lines on a ring or triangle 4 made, say, of three bars, see end view Figure 11.
These lines 3 are beyond the ring or triangle 4 united into a loop to which the log line
is connected.
The log line for both kinds of log I prefer to make with strands some or all of
which have copper or other suitable wire core, thus ensuring strength and lightness.
Figure 12 shows the rotator for a taffrail log. As in the case of the towing log the
knotted end of the line or loop may be passed through a screwed-on cone ferrule such
as k, Figures 1, 2 and 6, or as shown in Figure 12, and as I prefer it, I enter the line
by a lateral hole k¹, and, having formed a knot on the end of the line, I pull the knot
into the interior cone socket. The rear end of the rotator is formed with an air

of the register of a taffrail log, substantially as described and shown.
