edges upwardly converging to fit the under-
cut walls 12 of the swing plate, the bar sec-
tion of the swing lever being of a size to fit
slidably in the swing plate, so that the swing
Slever is capable of sliding movement With
relation to the swing plate, but held against
other than such movement. The forward
end of the swing lever overlies the rear end
of the latch bar, being formed in the upper
10 edge with a transversely arranged recess
21 adapted to receive a projection 22 de-
pending from a spring strip 23 which is se-
cured at its forward end to the latch bar 7,
the construction providing, as will be ob-
15 vious from the drawings, a means whereby
the latch bar may be moved to and from un-
latching position without a corresponding
movement of the swing lever, while in the
movement of the swing lever in one direction
20 the latch bar will be correspondingly
moved. Furthermore, as the prjection 22
and recess 21 are arranged transversely of
the parts, it is obvious that the forward end
of the swing lever may be moved laterally
25 without inducing a corresponding movement
of the latch bar, or, in other words, a lat-
eral movement of the swing lever will free
the connection between said lever and latch
bar.
30 In the arrangement of the operating
mechanism described it will be obvious that
the latch bar may be freely operated through
the finger member 10 to latch or unlatch the
door in the usual manner, it being under-
35 stood in this connection that by preference
the latch bar is returned to latching posi-
tion automatically by the use of any of the
usual spring means to this end.. It will also
be apparent from the above description taken
40 in connection with the drawings that in the
rotation of the main shaft 3 in one direction
the operating disk 4 is turned with the shaft
and the disk head 16 of the swing lever ef-
fected by such movement in the following
45 . manner : As the operating disk 4 turns in the
proper direction the pin 5 will move the
swing lever longitudinally, such movement
being permitted by reason of the elongated
slot or aperture 17 in the disk head of said
50 lever. The longitudinal movement of the
swing lever will, through the engagement of
the recess 21 in said lever with the projec-
tion 22 of the spring strip, withdraw the
latch bar from latching position, releasing
55. the latch nose from the keeper and freeing
the door. This movement of the disk head
16 of the swing lever has been such as to
cause the forward wall of the slot 19 of
the disk head to contact with the door
60 swinging pin 6, so that in the continued
rotation of the main shaft the pins 5 and
6 fix the respective disks 4 and 16 together so
that the movement of the disk 4 will simi-
larly operate the disk 16. As the disk 16
R5 turns the forward end of the bar sections ofthe swing lever moves outwardly and by its
pressure against the side of the swing plate
will force the door to open position, the
swing plate turning on its pivot during such
operation and the swing lever sliding longi- 7
tudinally of the plate. A reverse movement .
of the parts through the operation of the
main shaft in the .opposite direction will
close the door.
In providing for the control of the door 7
operating mechanism I secure to the bottom
board 24 adjacent the-driver's seat what may
be termed a leer plate 25, said plate being
formed with longitudinally extending spaced
fingers 26 providing in the present instance 80
three control slots 28, 29 and 30, it being un-
derstood that one control slot must be pro-
vided for each operating mechanism. The
fingers 26 do not extend the full length of
the interior opening of the lever plate and 85
are preferably formed with diverging ends
to provide flaring entrances to the center
slot. The lever plate which is generally of
rectangular skeleton outline has the inner
edge of its forward bar formed with a slot go
31 which slot is preferably alined with the
central control slot. The lever plate carries-
a foot lever 20 of preferred form which
lever is pivoted 'for movement longitudi-
nally of the lever plate in a pivot lug 32 ea
which pivot lug is in turn pivoted to a pro-
jection 33 depending from the lever plate,
the latter pivotal connection permitting a
lateral play of the foot lever. The foot lever
is thus mounted for a longitudinal and lat- 100
eral swinging movement whereby it may be,
at the will of the driver, positioned for en-
trance to either of the control slots and then
moved longitudinally of said slot. This de-
tail of construction is not particularly ma- 105
terial to this invention, as this form of lever
movement is not new in automobile struc-
tures, and I1 contemplate any preferred ar-
rangement a't this point. The foot lever is
connected with the lever plate through the 110
medium of a spring 34, which spring is ar-
ranged and tensioned to normally position
the foot lever in the slot 31 when pressure
upon said lever has been released. Depend-
ing from the lever plate are lugs 35in which no
is mounted a shaft 36, and on which shaft
are pivotally mounted for independent
movement pressure levers 37, 38 and 39, said
levers corresponding in number to the num-
ber of control slots and the upper end of io
each lever projecting through its particular
control slot. The upper end of .certain of -
the levers are formed with a -U-shaped ter-
minal 40 of a size to receive the foot lever:
so that said foot lever may be moved within 125
said terminal 'and then operated to actuate
the pressure lever positively in both direc-
tions throughout the length of the control
slot, the levers 37 and 39 being limited in
their inward movement by the inner walls 1s
