VIII you please answer the follow
ing.
No. which is the most practical,
chain or a shaft drive?
No. which will run with the
most power
No. 3-Wh!ch viii run the faster?
No. PLEASE explain the adyan-
tages and disadvantage of each.
No. winch viii give the most
power. FOR the same amount oi gas
and oil. a two-eycle or fouE-cyc'e en-
gine7
30. which Is the best, a one
cylinder two-cycle or two-cyl!nder
four cycle?
No. SIS there any difference IN a
ton engine fur pulling. or one-t YIN
der two-cycle or two-cylinder four
cycle?
No. s-Will a two-cycle heat quick
er than d iour-cylinder?
No. lO-ENplaln other d.sadVan-
tages and advantages of each.
H. II. A.
\. A. To speed and power there II
little to choose between the chain ana
shaft drive. The chain drive has the
great fault Of being NOISY, eliminating
IL as "A drive Tor pleasure cars. IL IL
also liable Ia be dirty. has the danger
Of links breaking, Of coming off It's
sprockcts when worn, and requires
skill In adjusting it, necessary radius
rods. IL has the great advantage OF
permitting the use Of u solid or dead
rear axle. and IL has also been found
that car equipped with IL will not skid
10 freely.
As to the two and four-cycle engine.
the four-cyclc which l. high-sIccd
engine, Will usually give more power
for the same amount Of gas and oil
than will the same size slow speed
two-cyclc engine.
\ direct answer cannot be given To
your seventh question, In regard To the
onc-cylindcr two-cyclc and two-cylin-
der four-cyClc. This depends entirely
upon the purpose for which the engine
is used. the conditions under which II
runs. etc.
No. s-A properly designed two
cycle onc-cylindcr engine will pull ~
well ns the same size two-cylindcr
four-cycic engine, this being entirely "a
matter OF the bore, stroke, speed, etc.
No. D-'This, too, viii he determined
by the design OF the engine and Its
cooling system. II anything, the four
cycle will tend To heat the quicker.
The two-cyciinc engine Is an excel
lent engine Tor hcaNN loads NJ low ahu
practically uniform speeds. Its alb
sencc OF valves and simplicity makes II
ideal when used In of-thc-way
places or In the hands of the non
mechanical.
The tour-CyClc Is high-spccd, also
yariablc-spccd engine. AS rule II Is
al lao al.
IL Is, however, more complicated and
requires more care than does the two
cycle.
q. ] have forty-volt dynamo run
by a small gns engine, on the farm,
for lighting purposes. IL has switch
board with volt meter and rhoosht all
connected. Can l Install storage bat
terry so as 10 have lights In the garage
when the dynamo is shut down and
can ! charge the battery from the dy-
namo2 II SO, what battery would you
advise me TO get?
The dynamo is marked 40 volts and
ampheres, aud switchboard 80 volts.
is ohms and Il amps.
The bulbs | am using and give sat
isfactlon, are 40 volts and 40 watts.
II. o. 7.
A. II will be entirely practical and
comparatively simple TO do rs YOU de-
sire. You will, however, require abuIt
twcnty-ccli battery, unless you use
bulbs of lower VOLTAGE In the garage.
III You bought the twcnty-ccll battery,
you could also connect IL up 10 the
house circuit so rs 10 have lights for
very short time after the dynamo has
been stopped.
As nine ampcrcs Is not very fast
charge for battery, you would bc
able tn connect from the dynamo di- I
rect 10 the battery, connecting the
