We, WALTHER TIMMERMANN, of 15, Alsterufer, Hamburg, Merchant, and HEINRICH
DELLSCHAFFT, of 34, Abendrothstrasse, Hamburg, Office Messenger, do hereby
declaře the nature of this invention to be as follows:-
Lifting gear such for instance as cranes, windlasses and the like are frequently fitted
with weight indicating devices for ascertaining the exact weight of the loads to be lifted
so as to check the exact aggregate weight lifted by the respective lifting mechanism
in a given period.
Now the object of this invention is to exactly ascertain the loads successively lifted
and to very accurately indicate the weight thereof.
The accompanying drawing represents
weight usually employed above the hook.

Figure 3 represents the paper-band feed mechanism.
Figure 4 shews the guide for the paper roll.
Figure 5 is a section on line x-x of Figure 1 and
Figure 6 is a plan shewing the guide of the grooved spindle represented in
Figure 1.
The improved checking device is preferably directly connected with a weight indi-
cating mechanism, and in this case the checking device as well as the indicating
mechanism are arranged in the interior of the weight above the hook.
The spring-
actuated hook a is depressed as it lifts the load and during this operation the spindle c
provided with a helical groove upon its periphery is caused to turn by means of a
fixed pin while at the same time the toothed wheel d mounted on the spindle is
rotated and transmits the motion by the bevel wheels 1 and 2 respectively, to the
indicating mechanism as well as to the checking device. The bevel wheel d² is fixedly
mounted upon the shaft i of the checking device and by rotation of the said shaft the
figure roller e is actuated whereby the weight is registered. The roller e is provided
with raised figures adapted to be inked by an inking roller f whereby plainly visible
figures are printed upon the paper band o. This paper band o travels over a roller
whose actuating mechanism is automatically moved forward as the hook a is relieved
of its weight. Thus the hand feed of the paper is obviated. Upon the periphery of
the figure rollers e the figures indicating the weights are arranged spirally so that
the registration is effected even if the roller e should execute more than one revolu-
tion. In order to ensure that the paper strip o is always located above the respective
figures, a deep groove e¹ is arranged upon the roller e and runs parallel with the rows
of figures. A pin g is provided on the roller; its object being to permanently retain
the paper band o travelling with the roller above the figures, corresponding to the
extent to which the roller is rotated; these figures thus indicating the weights of
the loads. The paper roller or feed device is adapted to rotate in lateral bearings hh¹
the latter being adapted to move up and down in lateral guides (Figures 1
and 4). The roller device rests upon springs and can be pressed on to the figure
roller or disc by a chain or a rope m so that when a load is suspended from the hook

page_text: its weight can be ascertained and registered by pulling the rope or chain m down,
whereby the paper band o together with the roller device is lowered and the respective
weight recorded upon the band. As already mentioned the arrangement for dis-
placing the paper band o and simultaneously rotating the roller n upon which the
paper is wound is such that the disc b', mounted on the upper elongation of the hook
and fitted with the pin 6 which reascends as the hook is released, will in its upward
movement grip the bottom end of a rod p pushing it upwards, and turning a ratchet
wheel by means of the pawl pl arranged thereon; the said ratchet wheel being
mounted on the shaft of the paper roll n. In order that as the paper-roll increases in
dimension by the paper gradually wound thereon, the increasing diameter of the roll
may not interfere with the operation of the feed mechanism an exactly adjusted
spring is inserted between the rod p and the pawl pl so that a regular feed motion
of the paper band o.is ensured irrespective of the increasing size of the paper
roll.
By this arrangement it is ensured that in case it should be omitted to pull the
chain in the blank space upon the paper band between two registering figures will
indicate that an omission has been made in weighing a load. The missing weight in
such a case can be ascertained by drawing the difference between the total suin found
and the sums registered upon the registering device connected to the checking
apparatus.
This apparatus described and represented in the accompanying drawing constitutes
an important improvement for all kinds of lifting gear seeing that the weight indi-
cating mechanism employed in connection therewith is controlled with certainty and
precision.

We, WALTHER TIMMERMANN, of 15, Alsterufer, Hamburg, Merchant, and HENRICH

Messenger, 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 :-

mechanism are arranged in the interior of the weight above the hook. The spring-
actuated hook is depressed as it lifts the load and during this operation the
spindle c provided with a helical groove upon its periphery is caused to turn by
means of a fixed pin 6 while at the same time the toothed wheel & mounted on the
spindle is rotated and transmits the motion by the bevel wheels d' and d² respectively
to the indicating mechanism as well as to the checking device. The bevel wheel d
is fixedly mounted upon the shaft i of the checking device and by rotation of the
said shaft, the figure roller e is actuated whereby the weight is registered. The roller e
is provided with raised figures adapted to be inked by an inking roller f, whereby
plainly visible figures are printed upon the paper band o. This paper band o travels
over a roller whose actuating mechanism is automatically moved forward as the hook a

periphery of the figure roller e the figures indicating the weights are arranged
spirally so that the registration is effected, even if the roller e should execute more
than one revolution. In order to ensure that the paper strip o is always located
above the respective figures, a deep groove e¹ is arranged upon the roller e and runs
parallel with the rows of figures. A pin g is provided on the roller its object being
to permanently retain the paper band o travelling with the roller above the figures
corresponding to the extent to which the roller is rotated; these figures thus indicating
the weights of the loads. The paper roller or feed device is adapted to rotate in
lateral bearings h h the latter being adapted to move up and down in lateral
guides (Figures 1 and 4). The roller device rests upon springs and can be
pressed on to the figure roller or disc by a chain or a rope m so that, when a load is
suspended from the hook, its weight can be ascertained and registered by pulling the
rope or chain m down, whereby the paper band o together with the roller device is
lowered and the respective weight recorded upon the band. As already mentioned
the arrangement for displacing the paper band o and simultaneously rotating the
roller n upon which the paper is wound, is such that the disc b' mounted on the upper
elongation of the hook and fitted with the pin b which reascends as the hook a is
released will in its upward movement grip the bottom end of a rod p pushing it
upwards and turning a ratchet wheel q by means of the pawl pl arranged thereon; the
said ratchet wheel being mounted on the shaft of the paper roll n. In order that as
the paper-roll increases in dimension by the paper gradually wound thereon the
increasing diameter of the roll may not interfere with the operation of the feed
mechanism an exactly adjusted spring is inserted between the rod p and the pawl p¹
so that a regular feed motion of the paper band o is ensured irrespective of the
increasing size of the paper roll.
By this arrangement it is ensured that in case it should be omitted to pull the
chain m the blank space upon the paper band between two registering figures will
indicate that an omission has been made in weighing a load. The missing weight in
such a case can be ascertained by drawing the difference between the total sum found
and the sums registered upon the registering device connected to the checking
apparatus.
This apparatus described and represented in the drawing filed with the Provisional
Specification constitutes an important improvement for all kinds of lifting gear
seeing that the weight indicating mechanism employed in connection therewith
is controlled with certainty and precision.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. An improved registering device for checking the indications of weight in
lifting gears, the characteristic feature being a shaft i connected with a weight
indicating mechanism; a roller e with figures arranged spirally upon its periphery
being mounted on said shaft; a paper hand o being adapted to travel over said

page_text: figures, this band being wound over rollers, displaceable in horizontal and vertical
direction and being connected with the roller e by a guide; the arrangement being
such that when the hook is loaded the weight can be registered by moving the
paper hand from outside against the figure roller e; the feed motion of the band
being effected by the upward movement of the hook subsequent to its release.
2. An improved registering device for use with lifting gear, constructed and
operating as and for the purposes herein before described and as illustrated.
