PROVISIONAL SPECIFICATION.
Improvements in Registering Devices for Use in connection with
Lifting or Hoisting Apparatus.
I, WILHELM ADOLPH AUGUST RÖPER, of Nos. 48 & 49, Luisenhof, Hamburg,
in the Empire of Germany, Merchant, do hereby declare the nature of this
invention to be as follows:
-
This invention relates to apparatus for registering the number of loads raised
or hoisted, of the kind in which a draw-bar provided with a hook capable of
closing and locking, and a system of levers connecting the draw-bar with register-
ing mechanism are arranged within a casing; by means of this device the register-
ing mechanism is operating each time the draw-bar is depressed by the suspension
of a load, the hook carrying the load being at the same time closed and locked,
the draw-bar again rising after the removal of the load and consequent unlocking.
The subject of the present invention is a modification of the above device
which I will now describe.
The draw-bar is replaced by an oscillating part upon the lower extremity of
which is formed or fixed the hook for the reception of the load, such part coming
into engagement with a locking device when it is depressed owing to the weight
of the load acting in opposition to a spring. When occupying this depressed
position the oscillating part is locked by the locking device; the hook upon this
part may be closed by its free extremity coming between two projecting portions
of the casing for example.
Instead of passing between such projecting portions of the casing, the extremity
of the hook may be caused to bear against a portion of the casing, thereby
closing it.
When the load is set down and the locking device removed from the oscillating
part by means of a key, the spring will act upon the part thus enabling the load
to be removed from the hook, which is now open.
By means of the registering mechanism, the number of loads hoisted is regis-
tered owing to displacement of the oscillating part.

[Price Sd.]

page_text: invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The apparatus for registering the number of loads raised or hoisted described
in the Specification of a former Application for Letters Patent No. 11347 dated
18th May 1898 was characterized by the fact that a draw-bar provided with a
hook capable of closing and locking and a system of levers connecting the draw-
bar with registering mechanism are arranged within a casing; by means of which
device the registering mechanism is operated each time the draw-bar is depressed
by the suspension of a load, the hook carrying the load being at the same time
closed and locked, the draw-bar again rising after the removal of the load and
consequent unlocking. The subject of the present invention is a modification
of the device above referred to and is illustrated in the accompanying drawing,
in which
Figure 1 shows a front view of the load recorder, the front plate being omitted,
whilst
Figure 2 is a side view.
The improved registering apparatus consists of a suitable casing composed of a
frame g having a lug g¹ and side plates d with projecting parts . Within this
casing there is loosely arranged upon a suitable pivot or axle e a double armed
lever upon the lower extremity of which is formed or fixed the hook a¹ for the
reception of the load, whilst the upper extremity of said lever a is provided with
a cam face a adapted to act upon the push or slide rod f (or its friction roller f
respectively) of a suitable registering device F; the upper end of the lever a
being further provided with a hook shaped arm adapted to engage with a
spring actuated and key operated locking lever b. The lever a is under the
influence of a spring e and capable of being oscillated in a suitable recess or slot
of the frame g, either by the action of the said spring into the position indicated
by dotted lines or by the weight of the load into the position shown by full lines.
In this latter position the lever a is locked by the locking lever b and the entrance
or mouth of hook al by its being between the two projecting parts d closed in
such a manner that the load cannot be removed from the hook unless it is set
down in the position wanted, the locking lever b brought out of engagement with
the hook shaped arm by means of a key, and the hook-lever a a¹ by the
tendency of its spring c has resumed its original position shown by dotted lines.
The use and operation of the improved registering apparatus are as follows:-
The registering apparatus proper by means of the lug or eye g₁ of its casing is
suspended from the chain, rope and the like of a suitable hoisting device not
shown the load to be raised is hooked or attached to the hook a¹. On hoisting
or raising the load its weight causes the hook-lever a a¹ to swing against the
action of its spring c into the position shown by full lines. When occupying
this depressed position the lever a is locked against return movement by the lock-
ing lever which has come into engagement with the arm 3; the mouth of the
hook a being closed at the same time by the projecting parts of the side plate d.
In consequence of the oscillation of the lever a the push or slide rod f is pushed
upward and held in this raised position by the cam face a³ of the lever a, as this
will be clearly understood from the drawing. Owing to the movement of the
push rod the registering device is operated in order to indicate and register
respectively that a load has been raised.
+
To remove the load from the hook at it is necessary to set down the load at the
place it is intended to occupy and. to thus free the hook from the weight of the
said load. This being done the locking lever b is brought out of engagement
with to arma by raising the former by means of a suitable key (as this is obvious
from the drawing and fully explained in a former application above referred to)
The lever a thus released is then oscillated, or turned by its spring c into the
position shown by dotted lines, thus enabling the load to be removed from the
hook, which is now open. The push rod f f at the same time is allowed to
drop into its lower end position indicated also by dotted lines in Figure 1. The

page_text: whole apparatus is then ready to be used again, that is to say, for hoisting, indi-
cating and registering another load.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
A registering device composed of a double armed lever (a) fulcrumed in a casing
having a suspending lug or eye at its top, the lower hooked end of the said lever
projecting beyond said casing whilst its upper extremity is provided with a cam
face (a) adapted to act upon a rod of a registering device, the said end being
further provided with a hook shaped arm (a³) adapted to engage with a spring
actuated and key operated locking lever b substantially as set forth and shown
illustrated in the accompanying drawing.
