page_text: I, MICHAEL EDUARD REISERT, of Hennef on the Sieg, in the Empire of Germany,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to a mechanical arrangement for lifting the weights off
the weight tray of weighing machines.
The arrangement is hereindescribed by way of example, as applied to a weigh-
ing machine having suspended to its beam at one end thereof the pan, tray or
the like for the reception of the material to be weighed such as corn and the
like, and at its other end the tray for the weights.
Above the weight-tray there is mounted in the frame of the machine a shaft
To the free end
having two pulleys for the reception of either a chain or rope.
of these chains or ropes is attached a rail or girder from which depend lifting-
hooks for each weight. The weight lifting or suspension hooks may be common
hooks or they may be in the form of tongs or grippers.
To one end of the shaft is applied a hand-lever furnished with a pin and in
the path of the travel of the pin there is secured to the frame a catch.
The above described arrangement forms an elevating device by means of which
the weights may be lifted off the tray either in part or the whole as will be herein-
after more fully described.
The rail or girder carrying the hooks or the like may be lowered by the hand-
lever sufficiently so as to allow of hooking on to it all over, any of the weights
which it is desired to remove from the tray. If ordinary hooks are provided they
are inserted into the eyes of the weights, but if tongs or grippers or claws are
provided in lieu of the hooks they are engaged around heads on such weights.
The hand-lever is afterwards depressed so far as to enable the pin to engage
the aforesaid catch. If it is again required to alter the weights on the scale the
weight elevating device is lowered the weights engaged or disengaged and the
whole raised as before. The vertical elevation to which the weights are raised
is always the same no matter whether there is one weight or several, or all the
weights are to be removed from the tray.
The improved arrangement is particularly advantageous for weighing apparatus
or machines where heavy weights have to be used, for instance in self registering
weighing machines. These latter have their mechanisms often walled or boxed
in so that access to the weight tray is difficult.
In many of these weighing apparatus of large size the weights require alter-
ing frequently according to the material to be weighed for example grain (corn,
wheat, groats) and in such case the mechanical device for removing the weight
will be found to constitute an important advantage, while moreover it should
be noted that with this arrangement for lifting the weights as hereinbefore
described all the weights for removal are simultaneously and uniformly lifted off

removed separately one after another.

improvements relating to Weighing Machines.
I, MICHAEL EDUARD REISERT, of Hennef on the Sieg, in the Empire of Germany,
Engineer, 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:-
This invention relates to a mechanical arrangement for lifting the weights off
the weight tray of weighing machines.
The arrangement or device for lifting or taking away the weights is herein-
described by way of example, as applied to a weighing machine having suspended
to its beam at one end thereof the pan, tray or the like for the reception of the
material to be weighed such as corn and the like, and at its other end the tray
for the weights.
In order that my invention may be more fully understood reference is taken
to the accompanying sheet of drawings, wherein
Figure 1 is a side elevation and
Figure 2a front view of a weighing machine of the class above referred to
and supplied with the improved device for lifting off the weights.
Figure 3 shows a modification of the improved lifting off device.
Similar letters refer to similar parts throughout the several views.
In the example shown a designates the scale beam, b the receptacle for the
material and c the weight-pan or weight-tray of the weighing machine, of which
is shown but as much as is necessary for the full understanding of the present
invention.
Above the weight-tray c there is mounted in the frame of the machine a shaft d
having two pulleys e for the reception of either a chain or rope g. To the free
end of these chains or ropes is attached a rail or girder f from which depend lift-
ing-hooks for each weight h. The weight lifting- or suspension-hooks may be
common hooks as shown in Figures 1 and 2, or they may be in the form of tongs
or grippers k, as shown in Figure 3.
To one end of the shaft d is applied a hand-lever r furnished with a pin m,
and in the path of the travel of the said pin there is secured to the frame a
catch L.
The above described arrangement forms a lifting-off or elevating device by
means of which the weights may be lifted off the tray c either in part or the
whole, as will be hereinafter more fully described.
The rail or girder 7 carrying the hooks or the like may be lowered by the
hand-lever sufficiently so as to allow of hooking on to it all or any of the
weights which it is desired to remove from the tray. If ordinary hooks are
provided they are inserted into the eyes of the weights, but if tongs or grippers
or claws are provided in lieu of the hooks they are engaged around heads on such
weights (see Figure 3); The hand-lever is afterwards depressed so far as to
enable the pin m to engage the aforesaid catch 7.

before. The vertical elevation

page_text: to which the weights are raised, is always the same no matter whether there is
one weight or several, or all the weights are to be removed from the tray.
The improved arrangement or device is particularly advantageous for weighing
apparatus or machines where heavy weights have to be used, for instance in self
registering weighing machines. These latter have their mechanisms often walled
or boxed in so that access to the weight tray is difficult.
In many of these weighing apparatus of large size the weights require alter-
ing frequently according to the material to be weighed for example grain (corn,
wheat, groats) and in such case the mechanical device for removing the weight
will be found to constitute an important advantage, while moreover it should be
noted that with this arrangement or device for litting the weights as herein before
described all the weights for removal are simultaneously and uniformly lifted off
the tray and thus there is no loss of time as is the case when the weights are
removed separately one after another.
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
1 claim is:-
1. In combination with a weighing machine a device or arrangement for lift-
ing off or removing the weights from the weight pan or tray consisting of a
suitable elevating or lifting means, such as a lever-actuated rail or girder, pro-
vided with hooks, tongs, claws or like means designed to engage the ordinary
hooks or heads on such weights, substantially as and for the purpose set forth.
2. The improved means for lifting off or elevating the weights from the weight
pan or tray of weighing machines constructed, arranged and operating, substan-
tially as hereinbefore set forth.
