sufficient, but where the bar is quite long,
then more than a single magnet is necessary.
When the magnet or magnets 54 are ener-
gized then the bar 52 is moved in a direc-
5 tion to engage the pins 51 of the blocks 22
and withdraw the latter from engaging re-
lation with the heads 21 of the push keys
18 so that all the push keys which have
been locked after being pushed in are re-
10 leased and return to their normal positions
under the action of their springs 20. Thus
when the bar 30 is returned to normal posi-
tion all the keys 18 which have been actuated
are restored to their first positions, ready
15 for subsequent operation.
What is claimed is:-
1. In a car, a signal circuit, separate sets
of circuit terminals on the car, one set com-
prising coperative pairs of terminals,
20 means for causing the successive closing of
the terminals of one set by the progression
of the car, and' means inside, the car and
under the direct manual control of pas-
sengers for closing any cooperative pair of
25 the other set of terminals at will.
2. In a car, a signal circuit, a set of cir-
cuit terminals therefor on the car, a step
by step circuit closer on the car and mov-
able successively in a right line over the
S0 circuit terminals, another set of terminals
for the signal circuit, means within the car
and under direct control of the passengers
for closing any one of the second set of cir-
cuit terminals onto one of the first set of
35 circuit terminals, at will, and a releasable
locking device engaging the circuit closer
against retrograde movement.
3. In a car, a signal circuit,. a set of cir-
cuit terminals therefor and located on the
40 car, a circuit closer on the car for the said
set of circuit terminals, the closer being
movable over the same, means for causing
a step by step movement of the said. circuit
closer with. momentary contact with the
45 said circuit terminals, other circuit termi-
nals on the car, each individual to a corre-
sponding one of the first named set of cir-
cuit terminals and movable manually at will
to the closed circuit position, and means for
50 locking the actuated ones of the second set
of terminals in the closed circuit position.
4. In \a. car, a signal circuit, a series of
contact terminals for said circuit and lo-
cated on the car, a switch for each terminal,
55 a series of push keys on the car, each key
being individual to a switch and movable
at will into switch engaging position, means
for locking each key in the switch engaging
position, and an automatic circuit closer
60 on the car and included in the signal circuit
anid movable along the series of contact ter-
minals into circuit closing relation thereto.
5. In a car, a signal circuit, a series of
contact terminals for said circuit and lo-
65 coated on the car, a switch on the car foreach terminal, a series of push keys on the
car, each key being individual to a switch
and movable at will to engage a switch,
means for locking each key in switch en-
gaging position, a circuit closer on the car 70
included in the signal circuit, and means for
moving the circuit closer step by step along
the series of contact terminals into circuit
closing relation thereto.
6. In a car, a signal circuit, a series of 76
contact terminals on the car for said circuit,
a switch on the car for each terminal, a
series of push keys on the car, each key
being individual to a switch and movable
at will to engage a switch, means for lock- go
ing each key in the switch-engaging posi-
tion, a circuit closer on the car and included
in the signal circuit, means for moving the
circuit closer step by step in a right line
along the series of contact terminals into 86
circuit closing relation thereto, and means
for causing the return of the circuit closer
to normal position after traversing the cir-
cuit terminals.
7. In a car, a. signal circuit, a series of go
contact terminals, a switch for each termi-
nal, a series of push keys, each key being
individual to a switch and movable at will
to engage a switch, means for locking each
key in switch-engaging position, a circuit 95
closer included in the signal circuit, means
for moving the circuit closer step by step
along the series of contact terminals into
circuit closing relation thereto, means for
causing the return of the circuit closer to 100
normal position after traversing the circuit
terminals, and means for causing the return
of the actuated push keys to normal posi-
tion on the return of the circuit closer to
normal position. 10
8. In a car, a signal circuit, a series of
contact terminals, a switch for each termi-
nal, a series of push keys, each key being
individual to a switch and movable at will
to engage a switch, means for locking each iio
key in the switch-engaging position, a cir-
cuit closer included in the signal circuit,
means for causing the circuit closer to trav-
erse the series of contact terminals into suc-
cessive circuit closing relation at will, and 115
means for causing the return of the actu-
ated push keys to normal position simulta-
neously.
9. In a car, a signal circuit, a series of
contact terminals therefor, means for clos- io
ing the circuit at the circuit terminals in
succession, other circuit terminals connected
with the first named circuit terminals, means
for closing the second named circuit termi-
nals at will, means for holding the closed 125
ones of the second series of circuit terminals
in the closed position, and means for simul-
taneously releasing all the closed circuit
terminals of the second named series simul-
taneously to return to normal position.
