Improvements in Registering Devices for use in connection with
Lifting or Hoisting Apparatus.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
The improved apparatus which forms the subject of this invention serves to
register the number of loads transferred or displaced from one place to another
and for this purpose it is affixed to the rope, chain or the like which is employed
for raising or lowering the load.
The apparatus is characterised by the arrangement in a suitable casing to which
a hook for the load and an eye or lug for the hoisting chain are attached, of a
pivotally suspended locking device for temporarily closing the mouth of the said
load hook, and a registering mechanism, said reigstering mechanism being
actuated by the oscillation or displacement of the locking device the hook itself
exercising no effect upon it.
One of the numerous forms in which this invention may be carried into prac-
tice is as follows: A hook for suspending the load is rigidly fixed to the casing
whilst as a closing or locking member for this hook a spring actuated tongue or
bar is arranged within or upon an oscillating or swinging part or plate.
This plate being under the influence of a spring is pivotally mounted upon a
pin which is fixed in the casing: it is provided, upon one side of the locking
bar with a suitable spring-actuated detent or trigger-bolt which engages a notch
or shoulder of the locking har in order to hold this bar in its forward or cocked
position against the tension of its spring. In proximity to the trigger-bolt a
keyhole is provided in the swing-plate and this keyhole comes in line with another
keyhole in the wall of the casing when the swing-plate or the locking bar re-
spectively occupies the closing-position so that a key may then be inserted through
the registering keyholes for operating the trigger-bolt.
Within the casing is also provided a catch-lever having a projection or arm
at its lower portion; this catch is arranged in proximity to the swing-plate
herein before referred to and a second keyhole is provided in the casing wall in
order that the catch-lever may be disengaged from a nose or projection of the
swing-plate by means of a second key.
As the registering apparatus which forms the subject of this invention is
arranged for loads of at least some hundred-weights, the spring retaining the
swing-plate and locking bolt respectively may be of such strength that the lock-
ing device cannot be pressed away towards the shaft of the hook by ordinary
manual force, in order that the swing-locking-device may not be liable to be
displaced with fraudulent intent,

page_text: The device above described is only a constructional example of the hook lock
or closing device. The invention embraces and includes all closing devices
owing to the displacement of which the registering mechanism is operated, whilst
the hook itself exercises no effect upon the registering mechanism. For example
the end of the hook may constitute the closing device for the same; this may be
effected by pivoting it upon the hook in such a manner that it is capable of being
locked and displaced, these operations acting upon the registering mechanism.

Improvements in Registering Devices for Use in connection with
Lifting or Hoisting Apparatus.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, 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:-
The improved device or apparatus which forms the subject of this invention
serves to register the number of loads transferred or displaced from one place to
another and for this purpose it is affixed to the rope, chain or the like which is
employed for raising or lowering the load.
The device or apparatus is characterised by the arrangement in a suitable frame
or casing to which a load-support or hook for the load and an eye or lug for the
hoisting chain are attached, of a pivotally suspended locking device or mousing
for temporarily clearing and closing the mouth of or entrance to the said load
hook and a registering mechanism, said registering mechanism being actuated
by the oscillation or displacement of the locking device or mousing, the hook itself
exercising no effect upon it.
In order that my invention may be more fully understood, I will now proceed
to describe the same in detail and for that purpose reference is taken to the
accompanying sheet of drawings wherein:
Figure 1 is a side elevation of the apparatus as it appears after the removal of
the front plate or cover; the parts being in the locking position: and
Figure 2 is a similar view showing the parts pushed aside by the load attached
to the hook, and being about to return into their locking position.
Figures 3 and 4 are views similar to Figures 1 and 2 respectively, but showing
a modification.
Similar letters refer to similar parts throughout the several views.
A hook a¹ for suspending the load is rigidly fixed to a suitable casing G,
whilst as a closing or mousing for this hook an oscillating or swinging part or
plate is pivotally arranged within the casing G upon a pin c. The free end of
this plate being under the influence of a spring projects into the entrance
of the hook a¹.
Within the casing G is also provided a catch-lever having a projection or
arm 71 at its lower portion: this catch is arranged in proximity to the swing-
plate b. and a keyhole m is provided in the casing wall in order that the catch-
lever, may be disengaged from a nose or projection o of the swing-plate b
by means of a key n. Within the casing, or suitably connected therewith, is

page_text: furthermore provided a registering mechanism R of any convenient and well
known construction. The push-rod a of this registering mechanism is operated
by a cam face b¹ of the swing-plate b, on displacement of the latter (whether it
be its inward or outward oscillation, or both); the said cam face acting upon a
friction roller of the push-rod a. For suspending the registering apparatus,
or casing G respectively, from the chain or rope of a hoisting device, a suitable
lug or ear is attached to the top of the casing G.
The device or apparatus may be used as follows: Assuming there are loads at
the same time to be registered and transferred from one place to another, for
instance from a steam-boat into a barge or lighter, then the man on board the
ship who attaches the load to the hook a¹ as well as the man on board the barge,
who removes the load from the hook a will receive each a separate key n for
operating or releasing the catch 1. The load to be raised and brought from the
steam boat into the barge is hooked or attached by means of a loop s or the like
of a suitable sling, sling-dog, strap-chain or like device to the bill of the hook a
(in the drawing this loop s is shown by dotted lines), after the man on board the
steam-boat has disengaged the catch or ratchet-lever from the nose of the
swing-plate by turning the said catch or ratchet lever by means of the key n
into the upright position shown by dotted lines in Figure 1, in which position,
it is retained by its lower arm resting against the face or edge of the swing-
plate b, as this is obvious from Figure 1. On hoisting or raising the load, not
shown in the drawing, the ear or loop s with which the load is suspended from
the hook, slides down the curved inner ridge of the hook, and by its weight
causes the swing-plate d to swing against the tension of the spring k towards
the shaft or shank of the hook, whereby the mouth or entrance of the latter is
opened and the loops from which the load is suspended enabled to slide down
underneath the lower end of the swing-plate wholly into the hook.
By this
inward oscillation of the locking device also the previously disengaged catch-
lever resting or bearing with the arm or the like against the swing plate b
is caused to tilt back so that it now rests or slides with its hook upon the edge
of the swing-plate, (see Figure 2). As soon as the loop s of the load has passed
underneath the swing-plate the latter is oscillated or turned back by its spring k
into its former position, in order to again close the mouth of the hook and to
prevent thereby any fraudulent removal of the load from the hook. At the same
time the swing-plate reaches the closing or locking position the catch lever
slides or snaps over and behind the nose of the swing plate thus securing the latter
against any movement, (see Figure 1). Owing to this oscillation or displacement
of the swing-plate or mousing the push-rod a is operated by the cam face b¹ of
the swing-plate 6 in such a manner as to indicate the suspension of the load.
After the load by means of the hoisting device has been transferred to and
deposited at the place at which the load is to be removed from the hook, that is
to say, after the load has descended into the barge, the man in this craft who
holds the second key n, disengages the catch-lever and presses the swing-plate b
back towards the shank of the hook thereby unbarring the entrance of the latter
and allowing the load or the loop s of its attaching means respectively to be re-
moved from the hook. After the removal of the load, the swing-plate is allowed
to swing back, under the action of its spring k into its former position, in
order to again close the entrance of the hook. The hoisting chain with the
therefrom suspended registering device is then shifted onto the steam-boat, in
order to unload, in the same manner as described, a second load, and so on.
In the modification shown by Figures 3 and 4 the swing-plate has a some-
what modified shape and is provided with a spring actuated tongue or bar d
arranged within or upon the said swing-plate; it is this locking bar d in com-
bination with the swing-plate, which forms in this case the mousing proper..
The swing-plate is moreover provided with a suitable spring actuated detent or
trigger-bolt e f which engages a notch or shoulder of the locking bar din
order to hold this bar in its forward or cocked position against the tension of its

page_text: spring 9. In proximity to the trigger-bolt e a keyhole is provided in the
swing-plate and this key-hole registers with another keyhole in the wall of
the casing G when the swing-plate b, or the locking bar d respectively, occupies
the closing-position (Figure 3) so that a key p may then be inserted through the
registering keyholes and for operating the trigger-bolt e.
The modified device or apparatus may be used in the following manner: The
man who attaches the loads to the hook receives the key n, and the man who
removes the transferred loads from the said hook receives the other key p. The
attaching of a load to the hook is performed in quite the same manner as described
above with reference to the apparatus shown in Figures 1 and 2, that is to say,
the loop s hooked to the bill of the hook, (Figure 3), slides on hoisting the
apparatus or the load respectively, down the inner ridge of the hook and causes
the locking bar d and the swing-plate to swing against the tension of the
spring towards the shank of the hook. whereby the entrance of the latter is
opened and the loop s enabled to slide down underneath the lower end of the
locking bar d wholly into the hook, (Figure 4). As soon as the loop s has
passed underneath the locking bar d the latter and the swing-plate 6 are turned
back by the spring k into the mousing position, in which they are again locked
by the catch lever in the manner already described above. The operation of
the registering mechanism also admits of no chance.
After the load has been transferred and lowered down at the proper place the
man who holds the second key p, that is to say the key for the locking device,
puts this key in the registering key holes and h of the casing and of the
swing-plate respectively and by turning the said key draws back the trigger
bolt e, whereupon the thus freed locking bar d shoots inwardly into the casing G,
thereby opening or unbarring the mouth or entrance of the hook a¹ thus allowing
the load or the loop s of its attaching means (sling, sling-dog, strap-chain) re-
spectively to be removed from the hook. The inward position of the locking
bar d shown in Figure 3 by dotted lines.
After the removal of the load the man
holding the key again cocks the locking bar d by moving the same against its
spring outward of the casing and into its former already described closing or
locking position in which the said locking bar is again retained by the trigger-
bolt e as described above in order to again bar the mouth or entrance of the hook.
The cocking or displacing of the spring-actuated locking bar d may be effected
by means of the same key by which the trigger bolt e had been previously
released. For this purpose the locking bar d is provided with a shoulder upon
which acts the kev on its being turned around, as shown by dotted lines in
Figure 3. The hoisting chain with the registering apparatus and the barred hook-
is then shifted onto the first place in order to transfer, in the same manner as
described, a second load and so on.
In this modified registering apparatus the spring k retaining the swing-plate b
and locking bolt d respectively may be of such strength that the mousing or
locking device cannot be pressed or pushed away towards the shank of the hook
by ordinary manual force.
The constructions above described are only constructional examples of the hook
mousing or closing-device. The invention embraces and includes all mousing or
closing devices owing to the displacement of which the registering mechanism
of the registering apparatus is operated, whilst the hook itself exercises no effect
upon the registering mechanism. For example the end of the hook may con-
stitute the closing device or mousing for the same: this may be effected by
pivoting it upon the hook in such a manner that it is capable of being locked and
displaced, these operations acting upon the registering mechanism.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, 1 declare that what I claim is :-
1. A device for registering hoisted loads which consists of a suitable frame

page_text: or casing, capable of being suspended, and provided with an immovable load-
support and with a registering mechanism, and of a movable mousing or locking
device to clear and close the entrance to the load-support, combined in such a
manner that on attaching and removing the load the mousing of the immovable
load-support is displaced and actuates the registering mechanism, substantially
as hereinbefore described and illustrated by the accompanying drawings.
2. A. modification of the registering device as claimed in Claim 1, in which
the entrance to the load-support is cleared or closed by a pendulous and retract-
able mousing which consists of a spring and catch controlled swing-plate or the
like provided with a sliding bar or like means capable of being projected into
and retracted from the entrance of the load-support substantially as herein before
described and illustrated by the accompanying drawings.
