Improvements in Registering Apparater, chiefly Designed for use in
connection with Cranes, Lifts, and the like.
I, MAX LUDWIG AMANDUS BOHLE, of 150, Banksstrasse, Hamburg, in the Empire
of Germany, Officer, do hereby declare the nature of this invention to be as
follows:-
-
The object of this novel apparatus is to register the number of loads hoisted, and
it is therefore adapted for use in unloading boats, ships, railway wagons and so
forth.
The mechanism of the apparatus is arranged within a casing of suitable form (a
box of cylindrical shape, for example) and consists of a draw rod provided with a
hook capable of closing, with an arrangement of levers engaging with the draw rod,
with registering mechanism acted upon by the said levers, two locking bolts and
with two springs.
One of these locking bolts is pivotally mounted upon one of the levers, is sup-
ported by a spring and is provided with a projecting portion intended to engage
the ward of a key, as will be hereinafter explained; whilst the other locking
bolt is rigidly fixed upon the other lever.
These parts are arranged within the casing in such a manner that the draw-
rod is capable of displacement and its hook is outside the casing, whilst the
arrangement of levers is connected with the casing by means of the pivot bolts
and gears with the registering mechanism by means of toothed gearing or its
equivalent.
The casing is suspended upon the rope, chain or the like, the load to be raised
being suspended by a hook. The rod is drawn downwards by the load, thereby
drawing out the lever arrangement whilst the locking-bolts lock one with the
other and maintain the draw-rod in its depressed position. Owing to the movement
of the levers the registering mechanism is operated and a mark made indicating
that a load has been raised.
The load cannot be released from the hook until it is set down in the position
it is intended to occupy and the hook freed from its weight. Until this takes place
a tongue or catch which is pivotally connected with the hook and by means of
a rod with the eye of one of the levers, prevents the hook from passing in and
only swings back the hook entrance when (the load being set down) the movable
bolt has been forced out of engagement with the fixed bolt by means of a key and
the draw-rod is again raised owing to the tendency of the springs of the arrange-
ment of levers to separate.
The load cannot be released from the hook therefore until the draw-rod has
resumed its initial position; a second mark will be made by the registering
mechanism as soon as a second load is hung upon the hook. Any fraudulent
attachment of one load after another whilst the draw-rod is drawn down, in order
that the registering mechanism may not record the second load is thus prevented.
The bolts must be released after each hoisting operation, whereby the rod is raised.
The registering mechanism is of course so arranged that it cannot be acted

page_text: upon by the upward stroke of the rod when it has registered a hoisting operation
on the descent of the rod, or vice versa, that it cannot be acted upon by the descent
of the rod when the upward stroke of the rod serves to effect the registering.
Finally, it may be so arranged that both motions of the rod are utilized for
effecting the registration.
Instead of the flat springs, other equivalent parts for raising the unloaded rod
may be provided.

Improvements in Registering Apparatus chiefly Designed for use in
connection with Cranes, Lifts, and the like.
I, MAX LUDWIG AMANDUS BOILE, of 150, Banksstrasse, Hamburg, in the Empire
of Germany, Officer, 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 object of this invention is an apparatus designed to register the number of
loads hoisted. and it is therefore adapted for use in unloading boats, ships, railway
wagons and so forth.
In order that my invention may be fully understood, I will now proceed to
describe the same, and for that purpose I shall refer to the accompanying drawing,
in which,
Figure 1 is a side elevation of the apparatus, as it appears after the removal
of the front plate of the casing;
Figure 2 is a similar view showing the parts of the apparatus in their working or
registering position, that is to say, when acted upon by a load attached to the
hook of the apparatus; the load not being shown in the drawing.
Similar letters refer to similar parts throughout the several views.
The mechanism of the apparatus is arranged within a casing G. of suitable form,
and consists of a draw rod a provided at its lower end with a hook a' capable of
being temporarily closed by a separate link d, and of an arrangement of
levers cc cc engaging with the draw rod a and with a suitable registering
mechanism R acted upon by the said levers, together with two locking bolts or
pawls and two springs ff or other suitable means of resistance.
One of these locking bolts or pawls bis pivotally mounted upon one of the
levers c, and is supported by a spring and is provided with a projecting portion 61
intended to engage the ward e of a key, as will be hereinafter explained; whilst
the other locking bolt is rigidly fixed upon the other lever c.
These parts are arranged within the casing G in such a manner that the draw-
rod a is capable of displacement and its hook a¹ is outside the casing, whilst the
arrangement of levers cel c¹ is connected with the casing by means of the pivot
bolts and with the registering mechanism by a connecting rod c³ or equivalent
means.
The casing is suspended from a rope, chain or the like (not shown) by means of
the eye G¹, the load to be raised being hooked or attached to the hook a¹.
The rod a is drawn downwards by the load, thereby acting upon the levers c c
and cc in such a manner, that the rod e³ is pushed upward, Figure 2, whilst the
locking-bolts or pawls 6 interlock one with the other and maintain the draw-rod c

page_text: in its depressed position. Owing to the movement of the levers and the rod a
the registering mechanism R is operated in order to indicate and register that a
load has been raised.
The load cannot be released from the hook until it is set down in the
position it is intended to occupy and the hook freed from its weight. Until this
takes place, a tongue or catch d which is pivotally connected with the hook a',
blocks or bars by means of a link g connected with one of the levers c, the entrance
of the hook a (Figure 2); and this catch d will swing back and free the entrance
of the hook (Figure 1) only when (the load being set down) the movable pawl b
has been forced out of engagement with the fixed pawl b by means of a key e
passed into the key-hole e the draw-rod a being raised at the same time by the
tendency of the springs f f to separate the levers cc (Figure 1).
The load cannot therefore be released from the hook until the draw-rod a has
resumed its initial position; a second mark will be made by the registering
mechanism as soon as a second load is hung upon the hook. Any fraudulent
attachment of one load after another whilst the draw-rod is drawn down, in order
that the registering mechanism may not record the second load is thus prevented.
The locking bolts or pawls must be released after each hoisting operation, whereby
the rod a is raised again.
The registering mechanism is of course so arranged that it cannot be acted upon
by the upward stroke of the rod when it has registered a hoisting operation on
the descent of the rod, or vice versa, that is cannot be acted upon by the descent
of the rod when the upward stroke of the rod serves to effect the registering.
Finally, it may be so arranged that both motions of the rod are utilized for effect-
ing the registration.
Instead of the flat springs, other equivalent parts for raising the unloaded rod
may be provided.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is;-
1. In registering apparatus chiefly designed for use in connection with cranes,
lifts, and the like, the combination of a suitable casing, a draw-rod provided with
a hook capable of being temporarily closed, a registering mechanism, a lever
arrangement connecting the draw rod with the registering mechanism, and a
locking device for the lever arrangement, substantially as and for the purpose
set forth.
2. The improved registering apparatus, chiefly designed for use, in connection
with cranes, lifts and the like, constructed, arranged and operating, substantially
as hereinbefore described with reference to and shown in the drawing annexed.
