EARLY HARPOON DEPTH SOUNDING MACHINE
by THOMAS WALKER
Not a Log
One of Walker's Rarest Inventions
One of his rarest inventions. Dated September, 1866
Presented
is only the second example of a Walker Sounding Machine with Patent Number 3652 that we have discovered. We
are unable to find a reference to it in our research books or elsewhere. This is not a ship's log which records distance
traveled, and is towed behind a vessel. This device is designed to go straight down and find the depth of the bottom.
It was made by Thomas Walker
& Son, Ltd of Birmingham, England whose name is synonymous with patent logs. The instrument has a
large impeller which drives a threaded gear that turns a disk which numbers from 2 to 30, in 2 digit increments, around its
circumference. On the backside is a similar disk which counts from 30 to 150 in 30 unit increments. It is our belief that
the unit of measure is fathoms so that the device reads from 2 fathoms or 12 feet to 150 fathoms or 900 feet. On the backside
there is a flap which drops down and locks the rotor when the device is raised and keeps the recorded depth from
unwinding. We do not know what purpose is served by the bronze bridle that came with it.
It is a straight forward design,
and should be in working condition, but it has not been tested. It has been polished and lacquered for your pleasure.

counter wheel, impeller and flap to its left | |

Thomas Walker's distance measuring apparatus are well known and still used
by ocean going sailors, and are likely part of all nautical collections. This Walker depth sounder is so rare that it should
be a part of any serious collection.

RARE THOMAS WALKER DEPTH SOUNDING MACHINE Like New Condition
Not a Log
One of Walker's Rarest Inventions
THOMAS WALKER DEPTH SOUNDER, Ca 1866
One of his rarest inventions.
Presented
is an excellent example of a Walker Sounding Machine with Patent Number 4139. This is the only example we have
ever seen, and can find no reference to it in our research books or elsewhere. This is not a log which records distance
traveled, and is towed behind a vessel. This device is designed to go straight down and find the depth of the bottom.
It was made by Thomas Walker
& Son, Ltd of Birmingham, England whose name is synonymous with patent logs. It features a self contained unit with
the distance measuring calculator as an integral part of the device. The instrument has a large impeller which drives
a threaded gear that turns a disk which numbers from 2 to 30, in 2 digit increments, around its circumference. On the backside
is a similar disk which counts from 30 to 150 in 30 unit increments. It is our belief that the unit of measure is fathoms
so that the device reads from 2 fathoms or 12 feet to 150 fathoms or 900 feet. On the backside there also is a flap which
comes down and lock the rotor when the device is raised and keeps the recorded depth from unwinding.
It is a straight forward design
so there is no reason to think it is not in working condition.
