..tf- The Ford Clutch,

y The Ford Clutch.
* The clutch of the Ford car is OF the
q disc type. and differs but little from
e the disc clutches on other cars. This
Il clutch. however. instead Of being placed
q in the nywhcel and being the next unit
* 20 the eng inc, rs is the usual pra ctice,
= is placed after the transmission or, i,
* might he said. 10 bc built into il.
+ The clutch is shown in figure /. and
S more completely in figure 4. All the
+ parts shown in heavy black are con
sglrected TO the rear wheels. while tho
E druni. y. OF figures ana >. is con-
nec;ed to shaft attached to the fly
y wheel, so that this drum will always
Z rcvolvc with the engine. Thus. if we
i, can arrange the clutch discs so that
when they are pressed together they
viii cause the drum. l.. TO he driven by
K the drum. y, we Will be able To drive
= the rear wheels by the engine.
4 To accomplish this il is only nee
E essary to- have the first disc with in
side offsets which vii! 1T into the kew
ways or slots. E of the drum, y. the
sncond to have external slots fitting
into the keys. y. of the drum, l.. the
h next disc like the first. the fourth
4 like che second, and SO on Thus when
/ the discs are pressed together. the
engine-drNen shaft. H. drum. y. the.
discs. the drums. I. and NJ. and so the
propeller shaft viii act as though they
were OF one rscce If the pressure is
taken off the discs, they will slip on
one another. and so the engine and
propeller snaft will be disconnected
Like on other clutches the pressure
com esd from spring, but in this car
the spring does not act directly on
the discs OF the clutch. but operates
! through three levers. These levers
press against fingers on the clutch
pressur,e plate, shown in figure and
iettered F in figure 1, the levers being
lettered u.
The pressure or the plates is -egu-
lated by the screws II. In making ad-
ius;nncTs;s oil, the clutch pressure. great
care must be- taken 10 have the pres
sure al all tHrec screws exactly the
same. II this i no; done, when the
clutch " let into engagement. there
will be a "chatte":nc' and the ear WILL
start with vibration, Perhaps tile
best way TO tighten these screws is
70 hold the wrench used always in the
same position. revolving the clutch in
order 10 do so. You will then be able
10 feel how much pull is required on
the wrench and have this pull equal
for all three bolts. After making the
adjustments. be sure that the bolts
are wired or locked, so that they cam
not unscrew Of their own accord
Like on other cars the clutch is dis
engag ed By taking the pressure OF the
spring of It. The mechanism by which
ihfs is done is SHOWN in figure g. You
Will observe that this can De accom-
pushed in Two ways. First. by the foot
. pedal shown at the left the pressing
( 10 the lett of which will cause the lef;
( portion of the lever, L, to be pressed
DOWN and so will move the fork. *. to
/ the right, thus COMPRISING tho spring
Secondly. by tho hand lever, which. by
MOVING the cam, W Will raise the
/ right side portion OF the lever L. and
( so also move X 10 the right. thus also
COMPRISING the spring
Drivers of Ford cars very often find
that, when they start the engine. IN.
I ear VIII start even though the hand
brake is on full way, and they must
run around and jump into the car and
I apply the foot brake.
( While the above is often due to the
low speed drum band binding. il Is
most often due 10 faulty adjustment

y, were TO be UP too high. that Tho
