.
My Invention has for its object certain Improvements applicable to Ship Logs
and the means used for connecting and communicating the revolutions of the
rotary part to the registering mechanism Also reducing friction, imparting
strength and durability, and thus remedying the evil arising from a tendency of the
Shaft Spindle or Arbor, hitherto employed to break or otherwise become injuriously
affected or out of action and the fog rendered useless for the purpose designed
when constructed on the principle described in the specification of the patent
granted to Thomas Walker dated 13th December 1861. N° 3130. and by such
improvements perfecting and preserving the action of the instrument rendering it
more effective and durable-Affording also greater facility in the operation of
ascertaining the depth of water by the log when employed for taking soundings,
and protection of parts of the machine from injury.
My said Invention consists in an arrangement whereby the shaft, spindle, or
arbor, as heretofore employed or used fixed in the rotary tube and working in the
tube which does not revolve, or the fore-end of the log is dispensed with, and in
lieu thereof, the substitution of a more suitable and preferable means-viz:-In the
centre of the rotary tube of the log is inserted a smaller tube, or a solid metal rod
supported at the fore-end axially in the lower face of a bearing at the aft end of
the interior of the tube containing the registering mechanism and passes through
a disc, or discs, or bearings in the rotary tube-or the bearing at the rear or aft
end of the tube containing the registering mechanism may be formed solid with
such smaller tube, or solid rod-Out of the centre on the upper surface of such Inst
mentioned bearing a small hollow cylinder, or tube is planted, with a rod carried
through the cylinder, the rod projects slightly through the bearing, and is acted
upon, and held in that position by a suitable spring-On the upper surface of the
DC11

page_text: disc, or bearing at the fore end of the rotary tube is a cuneated stud, hub, or
projection (or such stud, hub, or projection may be attached to or otherwise
connected with the interior of such tube) so pitched that as the tube revolves such
stud, hub, or projection comes in contact with, and passes over the end of the rod
projecting through the bearing, at the rear end of the tube containing tho
registering mechanism causing it to recede, and the other or upper end, or head
suitably formed, to work into one of the ratchet teeth of the first wheel, which it
moves, the movement being retained by a click acting on the wheel preventing
retrogression-the spring acting on the rod then forces it back, and to project
through the bearing, and so come in contact with the stud, hub, or projection on
the disc, or bearing in the rotary tube, or attached or otherwise connected with the
interior of such tube, and thus the motion of the first wheel is repeated, and each
suceeding revolution of the rotary tube, or aft part of the log is communicated to,
and actuates the registering wheelwork or mechanism contained in the other tubo,
or part of the log.
The rotary tube is prevented from being withdrawn, or separated froin the fore
part of the log by a nut plate fastened on the end of the inner, or smaller tube or
solid rod.
Or a rod may be carried through the tube in the centre of the interior of the
rotary tube, such rod being suitably planted at, or near the rear end or aft
part of the rotary tube-The rod is shaped at the fore end to form a cross head, or
arm, or lug, which as the rod revolves abuts against, or comes in contact with the
cross head, or arm connected with the worm and so imparts the revolutions of the
rotary-part of the log to and actuates the registering wheelwork or mechanism.
And of a curved metal bar frame, or appliance for holding and supporting the
Log when employed for ascertaining the depth of water, or sounding-furnished
with an eye hole at each end, the lower one for attaching the sinking weight, and
the upper one the line for recovering, and hauling on board; a portion of the curve
of the bar frame is devided longitudinally, and a part of the log, or case, or
cylinder (when used for inclosing the log)-adapted for the purpose, is placed
between the devided portions of the bar frame, and secured by screws, or slides,
thus forming a clamp, and so securely holds, and supports the log-Or instead of
dividing the bar frame, the log, case, plate, or cylinder may be adapted to clutch,
or embrace the bar frame, and be secured by screws, or other suitable means, and
the log is enclosed in a cylinder with ends sufficiently open to admit of the water
passing freely through-such ends being formed either by bars, or ribs of any
suitable shape curvilinear, or otherwise, placed horizontally, vertically, or otherwise
―or by wirework with adequate interstices-or by perforated metal.
For the purpose of further diminishing friction and imparting additional strength
the device for such purpose of Balls, or Spheres described in the specification of the
Patent granted to me dated 30th August 1876 N° 3412 may be substituted instead
of the anti friction rollers hitherto used, and which device, or Ball action may by
my improvements be placed in the interior of the rotary tube.

I JOHN EDWARD MASSEY of Number 17 Chadwell Street Clerkenwell in the
County of Middlesex manufacturer of Ship Logs and Sounding Machines do hereby
declare the nature of my Invention for IMPROVEMENTS IN SHIP LOGS OR MACHINES
FOR INDICATING THE DISTANCE TRAVERSED BY MARINE VESSELS AND ASCERTAINING
THE DEPTH OF WATER OR SOUNDINGS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
My invention has for its object certain Improvements applicable to ship Logs and
the means used for connecting and communicating the revolutions of the rotary
part to the registering mechanism-also reducing friction, imparting strength and
durability and thus remedying the evil arising from a tendency of the shaft,
spindle, or arbor, hitherto employed to break, or otherwise become injuriously
affected, or out of action, and the Log rendered useless for the purpose designed
when constructed on the principle described in the specification of the Patent
granted to Thomas Walker, dated 13th December 1861 N° 3130. and by such
improvements perfecting and preserving the action of the instrument, rendering it
more effective, and durable-affording also greater facility in the operation of ascor-
taining the depth of water by the Log when employed for taking soundings, and
protection of parts of the machine from injury.
My said invention consists in an arrangement whereby the Shaft, Spindle, or
Arbor, as heretofore employed, or used, fixed in the rotary tube, and working in the
tube which does not revolve, or in the fore end of the Log A, is dispensed with, and
in lieu thereof the substitution of a more suitable, and preferable means, as shewn
in Figure of the accompanying Drawings the letters following the several parts
herein named or referred to correspond with liko letters and parts delineated in the
accompanying drawings-viz: In the centre of the rotary tube B of the Log is
inserted a smaller or axial tube, or a solid metal rod C supported at the fore end
axially, in the lower face of a bearing D at the aft end of the interior of the tube
containing the registering mechanism, and passes through a disc or discs, or
bearings E. E 1. in the rotary tube or the bearing at the rear or aft end of the
tube containing the registering mechanism may be formed solid, with such smaller
tube or solid rod-Out of the centre on the upper surface of such last mentioned
bearing a small hollow cylinder, or tube F is planted, with a rod G carried through
the cylinder, the rod projects slightly through the bearing D-perforated for the
purpose-and is acted upon, and held in that position by a suitable spring H-On
the upper surface of the disc or bearing E at the fore end of the rotary tube is a
cuncated stud, hub, or cam projection I-(or such stud hub or projection may be
attached to or otherwise connected with the interior of such tube) so pitched that
as the tube revolves such stud, hub or projection comes in contact with and passes
over the end of the rod projecting through the perforation of the bearing D at the

page_text: rear end of the tube, containing the registering mechanism, causing it to recede, and
the other or, upper end or head suitably formed to work into one of the ratchet
teeth of the first wheel K which it moves, the movement being retained by a
click Lacting on the wheel preventing retrogression-the spring acting on the rod
then forces it back, and to project through the bearing, and so come in contact with
the stud, hub, or projection, on the disc or bearing in the rotary tube, or attached or
otherwise connected with the interior of such tube, and thus the motion of the first
wheel is repeated, and each succeeding revolution of the rotary tube, or aft part of
the Log, is communicated to, and actuates the registering wheel work, or mechanism
contained in the other tube, A. or part of the Log-The rotary tube is prevented 1
from being withdrawn, or separated from the fore part of the Log by a nut plate M
fastened on the end of the inner, or smaller tube or solid rod C-or a rod N may bo
carried through the smaller or axial tube C in the centre of the interior of the rotary
tube, such rod being suitably planted at, or near the the rear end, or aft part of the
rotary tube as shewn in Figures 5. and 6.-The rod is shaped at the fore end to
form a cross head, or arm, or lug, which as the rod revolves abuts against, or comes
in contact with the cross head, or arm connected with the worm O and so imparts
the revolutions of the rotary part of the Log to, and actuates the registering wheel-
work, or mechanism-And of a curved metal bar frame, or appliance P for holding
and supporting the Log when employed for ascertaining the depth of water,
or sounding, furnished with an eyehole at each end, the lower one for attaching
the sinking weight and the upper ono the line for recovering and hauling on board;
a portion of the curve of the bar frame is divided longitudinally as shewn in
Figure 7. of the accompanying drawings, and a part of the Log, or case, or cylinder
(when used for enclosing the Log) adapted for the purpose, is placed or inserted
between the divided portions of the bar frame, and secured by screws or slides thus
forming a clamp, as shown in Figures 7. and 8. on the aforesaid drawings and so
securoly holds and supports the log-Or instead of dividing the bar frame the Log,
case, plate or cylinder may be adapted to grip or clutch R, or embrace the bar
frame, and be secured by screws as shewn in Figures 9. and 10. of such
accompanying drawings or other suitable means, and the Log is enclosed in a
cylinder with ends sufficiently open to admit of the water passing freely through,
such ends being formed either by bars, or ribs of any suitable shape, curvilinear or
otherwise, placed horizontally, vertically or otherwise-or by wirework with
adequate interstices or by perforated metal.

For the purpose of further diminishing friction and imparting additional strength
the device for such purpose of Balls, or Spheres described in the specification of the
Patent granted to me dated 30th August 1876 N° 3412 may be substituted instead
of the antifriction rollers hitherto used, and which device or Ball action may by
my improvements be placed in the interior of the rotary tube.
