page_text: I, WILLIAM DAVID WHYTE, of 144, Broomielaw, Glasgow, Nautical Instrument
Maker, do hereby declare the nature of this invention to be as follows;-
1
This invention relates to sounding machines as used for navigational pur-
poses and it has mainly for its object to provide in connection with such machines
suitable gearing whereby the wire drum or wheel can, when winding up the wire
or rope,
be revolved at a much greater speed than the axle having the lever
handle or handles connected thereto. The general construction of the machine
is also improved.
In carrying out my invention I mount upon the axle or shaft of the machine
a drum or wheel upon which the wire or rope is wound and this drum or wheel,
by preference, consists of a strong metallic rim, which is or may be of a trough
shape with exteriorly projecting flanges, connected to a hub on the axle by
means of stout wire spokes which may, if desired, be tangential. Means are
provided such as a friction disc or its equivalent whereby the wire drum or wheel
or its hub can be clamped to the axle; or any other suitable and well known
clamping mechanism may be employed.
Suitable clock-work mechanism driven by means of a pinion made one with
or connected to a sleeve which can turn freely upon the axle of the machine is
provided for counting approximately the length of wire run out when taking
a cast. This pinion or its sleeve can be connected by an arm to the outer edge
of one side of the drum or wheel.
The drum is preferably made much broader and larger than usual so as to
readily receive the wire when it is being wound up and also owing to the increased
diameter of the drum or wheel to wind up the wire with a lessened number of
revolutions.
The machine is preferably enclosed in a sheath provided with springs or
depending pieces which bear against the flanges of the drum or wheel and pre-
vent the wire jumping out from between the flanges and over them.
The gear for driving the winding drum or wheel may be toothed wheel gear-
ing, chain and sprocket wheel gearing, friction gearing, belt gearing or any
other suitable and well known form of multiplying gearing. I prefer to use
an epicyclical gear having a rim wheel with pinions and a central gear wheel.

page_text: I, WILLIAM DAVID WHYTE, of 144, Broomielaw, Glasgow, 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;-
This invention relates to sounding machines as used for navigational purposes
and it has mainly for its object to provide in connection with such machines
suitable gearing whereby the winding drum or wheel can, when winding up the
wire or rope, be revolved at a much greater speed than the axle having the lever
handle or handles connected thereto. The general construction of the machine
is also improved.
In order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings which shows, by way of example,
one convenient method of constructing the machine.
Fig. 1 is a vertical cross section of the machine.
Fig. 2 is a vertical longitudinal section of the machine drawn to a smaller
scale.
Fig. 3 is a view of the multiplying gear.
Referring to the drawings whereon the same reference letters wherever repeated
indicate the same parts.
a is the frame of the machine. b is the driving axle or shaft provided with
a removable crank driving handle c, c. d is the drum or wheel upon which the
wire or rope is wound and which consists, by preference, of a strong metallic
ring of trough shape. e represents the wire coiled upon the wheel. f is the
ordinary clockwork mechanism, driven by the pinion 9, for counting the length
of wire run out when taking a cast. The pinion g is connected by means of the
arm to the catch on the wheel d. j, k, are the usual discs for clamping the
wheel. l, m, is the usual brake lever and nut. are the catches of the disc k
which work in the groove of the nut.
In my invention the axle b works within a hub i which is made with a thickened
part at its centre. The hub is carried in suitable bearings in the frame and is
cut with a left hand screw thread at . Keyed upon the part of the hub and
hard up against the collar is the metal disc j, provided, at opposite sides of the
disc, with the segmental wood blocks 1, 2, which, at their outer edges, are
inclined so as to bear against the side of the V shaped wheel d. Fitted loosely
upon the part of the hub is the second disc provided in a similar manner
with the segmental wood blocks, 2. The discs j, k, are as usual adapted to
lock loosely into one another so that the blocks j', j, k, form a complete
support for the wheel (see Fig. 2). Working upon the left hand screw ¹ is
the nut provided with the arm m which latter can, when desired, be caught and
held fast by the hinged catch n.
At the end of the axle suitable multiplying gear is provided for revolving the
hub. This gear may be of any well known and suitable construction. In the
machine shown on the drawings I have shown a gear which consists of a plate o
made one with the end of the axle and having four studs upon which four
pinions are loosely mounted. The teeth of the pinions 7 mesh, on the one
hand, with the teeth at the inside of the box r and, on the other hand, with the
teeth of a wheels fitted to the hub i. The gearing is clearly shown at Fig.
which is a section drawn to an enlarged scale and taken on the line X-X Fig. 1.
This gearing is arranged to multiply the speed of rotation transmitted from the

page_text: axle three times, that is to say, the arrangement is such that the hub i performs
three revolutions for a single revolution of the axle b.
t is a screw nut which retains the wheel s in position on the hub.
The wheel d runs loosely, with a light frictional resistance, between the fric-
tion blocks of the discs j, k when the wire is being paid out but when the wire
is being hauled in the wheel d is tightly clamped or held between the discs j, k,
and, as the disc j is keyed to the hub i, it is caused to revolve along with the
hub. This action is due to the movements of the nut 7 which can work laterally
upon the screwed hub and can be allowed to revolve with the hub or be prevented
from revolving therewith by means of the catch n. To clamp the wheel, when
hauling-in, between the discs j, k, the catch n is dropped so as to prevent the
nut revolving with the hub which latter is then revolved a few turns so as to
cause the nut to travel along the screw and force the disc & tightly against the
wheel which latter will then be held rigidly between the discs j, k. Thereupon
the catch is lifted up out of the way and the lever m and nut 7 allowed to
revolve along with the hub during the remainder of the hauling-in process.
To release the wheel d, when paying-out, the hub i is turned backwards, (the
nut being prevented from revolving by dropping the catch n so as to hold the
arm m) to such an extent as to cause the nut 7 and disc to release their pres-
sure on the wheel d which latter can then revolve freely.
The drum is preferably made much broader and larger than usual so as to
readily receive the wire when it is being wound up and also owing to the increased
diameter of the drum or wheel to wind up the wire with a lessened number of
revolutions.
The gear for driving the winding drum or wheel may be toothed wheel gearing,
chain and sprocket wheel gearing, friction gearing, belt gearing or any other
suitable and well known form of multiplying gear. I prefer however to use an
epicyclical gear, such as shown, having a rim wheel with pinions and a central
gear wheel.
Instead of having a single driving handle the machine may have two handles
as usual.
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 what
I consider novel and desire to claim is:-
1. The application and use in a sounding machine of multiplying gear whereby
the winding drum or wheel can, when winding up the wire or rope, be revolved
at a greater speed than the driving axle or shaft, substantially as herein before
described.
2. In a sounding machine the combination of a driving axle, multiplying gear
driven by the axle, a hub or sleeve fitted upon the axle and driven by the gear,
a winding drum or wheel, and means for connecting the winding drum or wheel
to the hub or sleeve, substantially as herein before described.
3. The general arrangement and combination of parts of the improved
sounding machine substantially as hereinbefore described with reference to the
drawings annexed.
