Improvements in Automatic Coin Released Weighing Machines.
I, PHILIPP REINER, of 31 and 33 Gutenbergstrasse, Cöln-Ehrenfeld, in the
Empire of Germany, Manufacturer, 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 has for its object improvements in automatic coin released
weighing machines.
A weighing machine in accordance with this invention is shown by Figure 1 in
front view and by Figure 2 in section from a to z of Figure 1 of the drawing.
Figure 2 shows some of the details.
Figures 3 and 4 are horizontal sections of the coin passage or guide. Figure 5
is a view from above (plan) of the locking lever.
To the rod a is attached the foot plate on which the load to be weighed is placed
and which is omitted from the drawing. The rod a in connection with the hanging
frame a rests, at its upper end, by means of the step a¹, on the knife a³, which is
rigidly connected with the suitably formed weighing arm 6 by means of the arm f.
To the front end of the arm f, a rod f¹ is fitted, which is connected with a piston
moveable in the cylinder 2, which is filled with a suitable liquid, in order to
prevent oscillation when the weighing machine is used.
The weighing arm b rests, with the knife ', on the step c.
To the weighing
arm, there is fitted, concentric to the axis of the knife , a toothed segment d,
which gears with the pinion e borne by the axle g. Upon the axle g there is also
fixed a fly g', which carries the tappet 2. In the prolongation of the axle g and
meeting it on the intermediate support w lies the axle k, which bears a friction
pulley provided with a groove, and a rope pulley ; to the latter is attached
the rope, provided with the weight . On the front end of the axle k is placed
the indicator, which plays over a numbered plate provided with suitable
graduations.
Behind the friction pulley k², there is placed a fly m with tappets m' and m²,
similar to the one on the axle g, and which is fitted to the axle k with a moveable
box and is pressed by a spring i against a pin k³ fixed upon the friction pulley.
The tappet m' is so long that it projects so far beyond the support was to come
into contact with the tappet g². Over the friction pulley 2, the catch arm n' with
catch is so arranged that the catch n, which fits exactly into the groove of the
friction pulley k², can, at the proper moment, catch in the groove. The catch arm
has at its other end the arm n² which is connected by a rod with a piston moveable
in a cylinder n³ filled with some suitable liquid. This piston is so arranged that it
can easily be dipped, while it offers a certain resistance to lifting. A pin a³, which
branches off from the hanging frame a², gears under the catch arm n' (Figs. 1 and 2)
so that it is lifted out of the groove of the friction pulley k³, when the weighing
mechanism is at rest. Exactly under the catch arm n', there is another suitably
guided releasing rod p'. The rod pl has its lower end connected with the arm p.
The arm p is in rigid connection with the fork shaped catch lever s, which in turn
is connected by a link s¹ with the lever s, one end of which projects into the coin

page_text: passage r.
To the coin passager is fitted a double arm lever q¹ g², which has its
fulcrum at v. A branch from the lower arm 92 is provided with a pin q³, which
projects into the coin passage. A second branch qq, goes round the coin passage r
(Figures 1, 3 and 4). The upper arm q¹ is connected with the rod 7, which is
provided at its end with an angular shoulder piece, against which the weighing
arın bears. At the middle of the rod y, there is a bell crank o fitted, provided
with a counterpoise o¹, one arm of which catches in the rod q and acts upon it in
the manner shown in Figure 1 of the drawing.
As is shown by Figures 1 and 5 the whole of the weighing and indicating
mechanism is stopped by the lever s². If a load is placed on the weighing machine,
the weighing arm is raised by the rod a, whereupon it strikes against the roller s³
and is held firm until a coin is thrown in. As soon as this is done, the coin falls
through the coin passage onto the levers which projects into that passage, and
presses it down (see dotted line position in Figure 1), whereby the weighing arm b
is set free and goes through a movement corresponding to the weight of the load,
so that the load on the foot plate is counterbalanced by the counterpoise 2. When
the weighing arm b, being set free, executes the said movement by reason of the
load on the weighing machine, the pinion e, gearing with the segment d, and, with
it, the axle g and the fly g', with tappet 2, are turned accordingly.
tappet g2 also holds the tappet m' of the fly m on the axle k, the axle k is likewise
turned, with the friction pulley 2 and the cord pulley upon the latter, the
cord, loaded with the weight 1, coils itself accordingly. The indicator attached
to the axle k is brought, by the turning of the latter, to that point in the graduation
of the index plate, which corresponds to the weight of the load.
As the
The coin thrown in at once leaves the coin passage 7, upon stepping onto or
placing a load on the weighing machine, after the release of the lever s, whereupon
the lever s is again drawn upwards by the counteraction of the weight s. In order
to prevent the levers or the locking lever from returning quite to its original
position, (whereby the weighing arm b, in the case of a small load, when its side
movement is also only small, would be hindered by the locking lever s² (or the
roller s³) the double arm g' g² with branch is provided, which, when the weighing
machine is at rest, assumes the position shown in Figures 1 and 3, but when the
weighing machine is at work, it executes its movement at the same time with the
weighing arm b, whereby the position of 91 92 93 and 7 in relation to the coin
passage so changes, that the pin q", (which, when the weighing machine was not
loaded, left so much room between itself and the coin passager that the lever s,
when pressed down by a coin, could pass unhindered but was held fast by the pin g³
until the weighing machine was loaded) now lies close up to the coin passage ; by
this means the pin g³ is also forced out of the coin passage r, so that the coin can
now leave the coin-passage and the levers can go right back until it strikes against
the pin q (see Figure 4).
If the levers is turned so far back that it strikes against the pin qs, the releasing
rod p will also have gone to far back, that the catch arm n¹ with catch n can drop
and catch in the friction pulley 2, whereby the index will be held fast in the
position corresponding to the weight of the load until the weighing machine is
completely released from the load consequently no other indication can be obtained
except after another coin has been placed in the slot.

When the weighing machine is released from the load, the weighing arm b
back to its original position, whereby the rod a, with hanging frame a and pin aº,
is lifted, and thus also the catch arm n', with catch n, is lifted out of the friction
pulley by the pin a³. As, by the return of the weighing arm with segment d,
9, with the fly g' and the tappet g², also returns to its original position, the
stop of the axle k is released, and the axle k, with the index, is brought back to
its zero position by the cord 1 and the weight 1.
the axle
At the same time, the rod q and the double arm q q² with pins 98 and 9³ are
brought back by the weighing arm b to the original position, so that the levers and
the locking lever 2 is released and likewise returns to its original position, whereby

page_text: the weighing arm b is again stopped. As is shown in Figures 1 and 3, the pin q³,
when the weighing machine is at rest, projects into the coin passager; the object of
this is, that a coin thrown in before stepping upon or placing the load upon the
weighing machine may release the levers or the locking levers, but cannot leave
the coin passage and must hold fast the releasing lever s until the weighing machine
receives a load, whereupon the various movements can proceed in the manner above
described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that I am aware
that it has been previously proposed to construct automatic coin released weighing
apparatus having a break between the weighing and indicating parts thereof and
also it has been proposed to construct weighing apparatus having a stop which
prevents the machine being set in operation till a coin is put in, and I wish it to be
understood that I do not claim generally such features of construction but what I
claim is :-
1. In a beam weighing machine acting automatically, or by means of coins, the
application of a locking appliance by which the weighing arm is stopped
substantially as described and shown.
2. In a weighing machine acting automatically, or by means of coins, the
application of a catch appliance for the purpose of holding the index, after it has
indicated the weight, until the weighing machine is entirely released from the load,
so that the last weight indicated always remains visible until the weighing machine
is entirely released or newly set to work, even if, after the index has once been
stopped, the load on the weighing machine should alter substantially as described
and shown.
3. In a weighing machine acting automatically, or by means of coins, the
appliance which permits of a coin being thrown in as well before as after stepping
onto or putting the load on the machine, and prevents the coin after unlocking the
weighing arm from passing out of action before its time, substantially as described
and shown.
4. The weighing machine substantially as described and shown.
