page_text: On the end wall of receiver is arranged the pawl q' against which rests the one end
of the double arm lever r, the other end of this lever is connected with the arm t
of the shutting off trap b by means of the rods (Fig. 3). The inner end of the
scale beam is provided with a pin u (Fig. 1) immediately before the scale adopts
its position of equilibrium said pin presses upon the pawl q¹ thus vibrating the
pawl and disengaging the lever which allows the trap 6 to close.
The arm of the trap carries the rod w which is provided with the nose *. On the
left of the wall of the box is arranged the pawl y against which rests the lever = of the
discharge trap a¹.
When therefore upon the closing of the trap b the arm t is raised, the arm v
is lowered and with the latter the bar w. As soon as the nose x touches the
pawly the lever is disengaged and thereby opens the discharge trap. On the
end wall of the case rests the shaft c¹ on the two supports b¹ which shaft carries at its
outer end the balance rod d¹ Fig. 1 the purpose of which is to regulate the discharge.
At the shorter arm of the balance rod is arranged the counterweight e¹ whilst the
longer arm is in connection with the regulating device by the cord or chain f¹.
In the discharge tube g¹ which runs through the centre of the bridge of the scale is
movably arranged the funnel shaped cup h¹, the side of which is fastened to the
shaft. At the outer end of this shaft is placed hook which is provided with
the counterweight k¹ and gears into the slide which latter slides up and down the
guide m¹ and is connected with the longer arm of the balance rod by means of the cord
or chain. Within the end wall of the case is arranged the trap Fig. 4 which by
means of the rod m¹¹ is connected with the lever n' fastened to the shaft c¹. As soon
as during the filling of the scale the grain poured in it exercises a pressure upon the
trap, the latter is pressed against the end wall of the case and in consequence
thereof the counterweight e located on the shorter arm of the balance rod d' is raised
by the rod m and the lever n¹ so that the slide moves downwards. As soon as the
balance begins to empty itself the cup his pressed down by the weight of the grain
travelling through, thereby the shaft is put into rotary motion so that the hook j
gears into the slot of the slide and holds the latter until the whole box is emptied.
As soon as no further pressure is exercised upon the funnel h¹, that is the receiver
is completely emptied the counterweight k¹ will act again. The hook is raised in
consequence thereof and the slide is liberated so that the counterweight e' located
on the balance rod comes now into action, the same pressing down the arm e by means
of the cord o¹ so that it opens the first shutting trap a. At the same time the slide
travels downwards and as during the emptying of the vessel the front part of the
balance raises itself the bent lever 9 and with it the disc h is turned so far
until the nose of the disc h engages into the slot of the slide and secures the
same.
P
The arm p¹ placed on the lefthand end of the pintle or arbor c of the first
shutting trap is raised according to the motion of the arm e and as the former is
connected with the lever of the discharge trap by means of the cord q¹¹, said lever is
raised likewise and the trap is closed.
At the righthand end of the pintle or arbor d of the shutting-off-trap is placed the
angle-piece, against which, when the first shutting trap is opened, touches the
arm and consequently the shutting-off-trap is also placed back into the filling-
position.
This angle-piece serves also at the same time as a counter-weight, in order to render
resistance to the pressure of the grain resting upon the traps.
By the closing of the shutting-off-trap the arm t and with the same also the rods
are pressed down so far until the double lever r rests again upon the pawl q'; at the
same time the arm v and with it the rod n are raised likewise; in the meantime
the lever z of the shutting-off-trap has become placed against the pawl y, so that all
parts are again in the position for filling and the operation may begin anew.
After each emptying of the receiver the hand of a counting device arranged within
the same is set into motion and moved on by one figure at a time.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
In an automatic balance for weighing cereals, and other granular matters and
liquids the combination of the receiver Con the balance bridge with the hopper or
equivalent A; the two feed traps a and b and the discharge traps a¹ together with the
means substantially as herein described and illustrated for respective operation of
the aforesaid traps in the manner set forth.
