IMPROVEMENTS IN AUTOMATIC WEIGHING MACHINES FOR WEIGHING GRANULAR AND PULVEROUS SUBSTANCES
Year: 1885

page_text: J, CARL REUTHER of Hennef on the Sieg in the German Empire, Manufacturer,
do hereby declare the nature of my invention for "IMPROVEMENTS IN AUTOMATIC
WEIGHING MACHINES FOR WEIGHING GRANULAR AND PULVEROUS SUBSTANCES" and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
My invention has reference to automatic weighing apparatus for granular and
pulverous substances for which Letters Patent have been granted to me bearing
date 16th August 1881 No 3551, 3rd April 1882 N° 1608, and 11th January 1884
No 1276.
My present improvements relate to improved means for loading the scale beam
so as to make it descend and cause the second slide G described in the said Patents
to effect a premature cutting off of the supply of material to the weighing machine.
According to the present improvements I employ in combination with the said
second slide G a weighted lever that, together with the slide is made to bear upon
the receptacle of the weighing machine, the tumbler weight by means of which the
requisite downward pressure is brought to bear upon the receptacle as also the
adjustable weight for adjusting such pressure, being arranged either upon the slide
or upon the weighted lever.
Fig. 1 of the accompanying Drawings shews one modification of the above
described arrangement in which the slide G is carried by an arm G₁ having its
fulcrum at el beyond which it is provided with the tumbler weight G². It rests
with knife edges Z in the loop of a rod H connected to the lever Y that actuates
the opening bottom of the receptacle, and which is pivotted to the receptacle,
so that the pressure of the slide Ġ and its arm G¹ is transmitted to the scale benin.
is a lever having its fulcrum on a bar X connected to the framing, while its other
end rests with knife edges in the loop of a rod H' also connected to the lever Y, and
pon it is mounted the adjustable weight V by means of which the load on the
cale beam is regulated. F is the first slide of the feed hopper, mounted on pivots
te as in the previous Patents before mentioned. In the modification at Fig. 2,
he arm G¹ of the slide G has no tumbler weight, a tumbler weight p¹ being
rovided on the lever v, which in this case carries the adjustable weight V on an
xtension beyond the fulcrum at X.

page_text: In the modification at Fig. 3 both the lever and the slide arm G¹ are provided
with tumbler weights, and the adjustable weight V is placed upon an extension of
the latter.
It will be seen that in the above cases the second slide G works on a separate
axis from that of the slide F, as was also the case in my Patent No 127684, but it
will be evident that the two slides might also be arranged so as to work on one
and the same axis, as in the other previous Patents. The other parts of the
machine are the same as described in my previous patents and need not be farther
described.
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 in respect of automatic weighing machines of the kind herein referred
to is
1. The combination of the slide G, its slide arm G¹, and tumbler weight Q with
the loaded lever v so as to load the scale beam, arranged and operating substantially
as herein described with reference to Fig. 1 of the drawings.
2. The combination of the slide G and slide arm G with the lever v and its
tumbler weight p¹ arranged so as to load the scale beam and operating substantially
as herein described with reference to Fig. 2 of the drawings.
3. The combination of the slide G, slide arm G¹ and tumbler weight G³ with the
lever and tumbler weight pl arranged so as to load the scale beam, substantially
as herein described with reference to Fig. 3 of the drawings.
4. The several modes of regulating the pressure of the slide arm G and lever v
upon the scale beam by means of the adjustable weight V herein described with
reference to Figs. 1, 2 and 3 of the drawings,
