of rods 47 extending transversely of the
machine and connected by other bell crank
levers 48 to other rods 49 in turn connected
by a series of' bell crank levers 50 to the
5 lower extremities of a corresponding series
of push rods 51 extending substantially par-
allel to the steering column 52 and having
their upper portions slidable through a
guide plate 53 shown for convenience as
io arranged under the hand controlling or
steering wheel 8, said rods being provided at
their upper extremities with heads or 'but-
tons 54 to enable the operator to press the
push rods 51 downwardly.. In addition to
15. the rods 51, an additional push rod 55 is
provided, the same being arranged in paral-
lel relation to the other rods and mounted
in the same manner and being used as will
hereinafter appear for releasing the- multi-
20 ple latch and bringing the gearing back
to a neutral condition. Each of the rods 51
is connected to its bell crank lever 50 by a
sliding joint in connection with which a
compensating spring 56 is employed so that
25 in case the operator depresses one of the rods
51 too' far, it will have no serious effect on
the other connections described.
Each of the push rods 51 is provided with
a stop shoulder 57 adapted to be engaged
30 by the bottom face 58 of a multiple latch 59
held yieldingly toward the series of push
rods 51 and 55 by means of a coiled expan-
sion spring 60 mounted in a combined guide
and housing' 61 as best illustrated in Fig.
35 8, said guide and housing being provided
with lugs 61' to secure the same in fixed re-
lation to the frame of the machine. Each
of the push rods 51 and 55 is further pro-
vided' with an inclined or cam shoulder 62
40 adapted to cooperate with a corresponding
cam face 63 on the latch 59 so that as. any.
rod 51 or- 55 is depressed, the latch 59 is
shifted so as to release any other rod which
may have previously been engaged and held
45 downwardly by said latch.
64 designates a bracket which supports
the shaft 65 on which the bell crank levers
50 are mounted to turn.
66 represents a foot lever which is fast on
50 a rock shaft 67 having fast thereon a bevel
gear wheel--68 which meshes with another
bevel gear wheel 69 fast on the adjacent end
of the clutch operating shaft 25 as shown
in Figs. 1 and .2. The upper portion of the
55 lever 66 is provided with a rack face or
teeth 70 adapted to be engaged and held by
a spring catch 71.shown as mounted in a
casing 72 secured to the floor member 10.
73 designates a pedal which is pivotally
60 mounted at 74 on the lever 66 and provided
with a trip arm 75 which by rocking thce
pedal 73 in the proper direction operates
against the point of the catch 71 and forces
the same out of engagement with the teeth
65 or rack face 70 thereby'permitting the lever66 to be retracted under the action of the
springs 24 (see Fig.-3), which act on the
straps-22 and thereby on the eccentrics 23 to
turn the shaft 25 back to its initial or neu-
tral position. 70
From the foregoing description, the op-
eration of the transmission gearing will
now be understood. Suppose, for example,
the transmission gearing is in neutral po-
sition and the operator desires to start the 7
car. He pushes downwardly on the proper
button 54 which acts through the connecting
rods and bell crank levers to shift the fork
36 by means of the arm 40 and simultane-
ouslyshift the fork which controls the lock-' 80
ing device for the clutch e by means of the
arm 39, it being remembered that the. arms
40 and 39 are both simultaneously operated
by the same.rod 41. The operator then de-
presses the foot lever 66 thereby turning the 85
clutch operating. shaft 25 and locking the
gear E to the shaft 4 and ' the gear A to
the shaft 6. The motion of the shaft 4 is
now transmitted through the gears E and
F to the countershaft 15 and then through, @0
the gears B and A to the shaft 6. The
machine is now in what is known as low
speed. In the same way the operator throws
the machine into second speed by depress-
ing the proper button 54 so as to lock the 95
wheel A to the shaft 4. The drive is then
from the shaft 4 through the wheels C and
D, the countershaft E and the wheels B and
A to the shaft 6. To obtain high speed or
direct drive, the proper button 54 is de- 160
pressed, thereupon connecting the. shaft 4
directly to the shaft 6 ,by means of the
clutch c. Reverse gear is effected by operat-
ing the clutch d thereby locking the wheel G
to the shaft 4. The drive is then from 105
the shaft 4 through the gears G, I and H to
the countershaft 15 and then through the
gears B and A to. the shaft 6. To throw the
gearing into neutral or inoperative condi-
tion, the operator depresses the rod 55 which 110
merely has the effect of tripping the mul-
tiple latch 59 and allowing the previously
depressed rod 51 to move back to its initial
position. As a whole, the construction and -
operation of the transmission gearing and 115
operating means therefor is extremely sim-
'ple. All the operator is required to do is to
first depress the proper button 54 which
leaves all of the other rods 51 free and also
releases - any one of the rods which may 120
have previously been depressed aifd held by
said latch. After depressing the proper but-
ton 54, the operator then depresses the foot
lever 66 until-it is caught and held by the
catch 71 coperating with the teeth 70. 125
It will be observed that the gears of the
several groups in the transmission case are
always in mesh whether idle or working and
that the gears of the shafts 4 and 6 are taken
up gradually without any jerking motion 1308
