diverted into the chute leading to the cash com
partment. ' The apparatus so far described is
similar to ‘that disclosed in the Forsberg patent;v I
. In accordancewith .a feature of this invention
a pair of tensioned elongated contact springs 40
2| and 22 are mounted vertically on the rear
outside wall of the coin hopper‘ IS. The springs
are secured to a bracket arm 23 extending from
the hopper housing by means of screws 24
threaded into the bracket arm. The springs are 45
insulated from one another and from the mount
ing bracket withv suitable insulating material
25., Each spring" member is provided with a
terminal 26 and 21 at the mounting endwhich
isconnectedtolead wires (not shown) running ,50
to' the central o?ice as described in the For's-V
berg patent.
The contact springs extend verticallyv down
ward and parallel to the hopper wall with their
unsupported ends approximately opposite the‘ 55
horizontal position of the coin trap.
A cam or
lug 28 made of insulating material and having
an oval cross-section projects from the edge of
the trap opposite the counterweight.
A suit
able opening is provided in the hopper housing
in its path by the short cam arm which engages
the bottom of the trap. This causes the vane
to permit the projecting lug to engage the free
ends of the contact springs which are formed
to receive the lug between them and hold it
to lift the trap to its normal or elevated position
and forces the insulated lug between the tapered
ends of the contact springs which separates the
contact disks on the springs and opens the coin

crcuits when a coin is deposited. Operation of the
line circuit ‘is directly responsive to the deposit 15
of a coin in the apparatus, thus insuring positive
and consistent performance, and the component
apparatus required to control the circuit is re
duced to ‘a minimum.
Other adaptations of this construction will be
‘apparent and it is to be understood that the in
vention is limited only by the scope of the ap
pended claims.
tions the springs are shaped to form a pair‘ of
On the inside
of each of these faces is a coating or disk 31 of
gold, silver, or other metal suitable for electrical
contacts, welded or otherwise secured thereto.
These contact disks are joined and separated in
15 parallel adjacent faces 29 and 30.
20 accordance with the position of the insulated lug
projecting from the trap to complete and inter
rupt the electrical circuit through the contact
In a complete cycle of operation the coin trap
25 assumes four signi?cant positions as shown in
Figs. 2, 3, 4, and 5. Normally, it is elevated to
its highest position, shown in Fig. 2, and retained
there by friction contact between the projecting
lug and the line switch contact springs. In this
30 position the lug holds the contact disks apart and
the line circuit is consequently open.
When a
coin 32 is deposited in the instrument the weight
of the coin on the trap overcomes this frictional‘
,resistance and de?ects the trap to its second po
35 sition against the roller on the coin directing vane
vas shown in Fig. 3. This movement shifts the lug
downward sui?ciently in the tapered spring arms
to permit the ‘springs to converge under their con
tained tension and join the contact disks, thus
completing the circuit through the springs and
the line running to the central oi?ce to signal the
coin deposit.
t an appropriate time the coin collecting or
refunding mechanism is actuated by the central
o?ice operator. This is done by rotating the vane
on its pivots, as previously described, which
causes the trap to drop under the weight of the
coin into its third position, shown in Fig. ‘l. A
suitable mechanism for actuating the coin direct
ing vane is disclosed in the Forsberg patent and
can be connected to the vane by a suitable link 33.
What is claimed is:
l. In a coin controlled apparatus, a coin chute,
a trap therein adapted to be deflected from its
normal position by the weight of a coin deposited
thereon, and a common means for holding the
trap in its normal position and initiating a sig
nal when a coin is deposited, comprising a pair 30
of tensioned contact springs, and a lug of insu
lating material projecting from the trap for nor
mally separating the tensioned springs and per
mitting the springs to engage when the trap is
de?ected by deposit of the coin,
2. In a coin controlled apparatus, a coin chute,
a trap therein adapted to be deflected from its
normal position by the weight of a coin deposited
thereon, means for holding the trap in its nor
mal position comprising a pair of tensioned .
springs, and a lug on the trap for projecting be
tween the tensioned springs and seeming the trap
in its normal position.
3. In a coin controlled apparatus, a coin chute,
a trap in the chute adapted to be de?ected by the 45
deposit of a coin thereon, a pivoted vane for nor
mally arresting the de?ection of said trap, a coin
deposit signal switch having a pair of cooperating
contact springs, a projecting lug of insulating ma
terial on the trap to normally separate the springs
and release the springs when the trap is de?ected
After the coin is released from the trap the
vane is returned to a vertical position by the ac
‘by deposit of a coin, means for pivoting the vane
tuating mechanism. During this motion the roller
and means secured to the trap for engagement
with the vane for restoring the trap to its normal
55 on the Vane and the counterweight on the trap
cooperate to raise the trap to a horizontal posi
tion. In order to break the signalling circuit
through the contact springs it is necessary to ele
vate the trap to its normal position above the
roller. This is accomplished by means of cams
34 hinged to the bottom of the trap and con
structed to engage the vane on its return stroke.
A detailed description of these cams and their
arm which is free to swing on its pivot to avoid
interference with the vane movement. On the"
return stroke of the vane, the long arm is held

L. Landreth, Serial No. 90,085, ?led July 11,
As shown in Fig. 6 the cam has .a short arm 35
and a relatively long arm 36 joined at approxi
mately 90°. When the coin directing vane is re
70 tated to release the trap, it engages the long cam
to- drop the trap and collect the deposited coin,
4. In a coin controlled apparatus, a coin chute,
a trap in the chute adapted to be de?ected a pre
determined distance from its normal position by
the deposit of a coin thereon, a pivoted vane for
normally arresting the de?ection of the trap
caused by the deposited coin, a coin deposit signal
switch, a lug of insulating material projecting
from the trap for contacting the switch, means
for pivoting the vane to drop the trap and col 65
lect the deposited coin, and a hinged cam on the
bottom of the trap to engage the vane on its re
turn stroke after the coin is collected for return
ing the trap to its normal position.
