TIRE PUMP NECESSITY
FORMANY CAR OWNERS
SAYS VET. 0LDF|ELD
Barney Tells of Four Distinct
Makes Now on Market
Helps. Cut Down the Bill.
BY BARNEY oLpEIELn

There are many devices and Access
series of various sorts that contribute
10 making the automobile the con-
venlent and pleasure giving vehicle
tnat II is at the present time. Some of
these accessories have become practi-
caliy necessities, others are still in the
luxury stage. After an accessory has
reached the happy state where it is
considered practical necessity, the
car manufacturers begin including it
with the car as stock equipment
This is slowly getting to be the con :
dition of the device that we know as
the power pump. A majority of the
car models produced in this country
now have tire pump a. stock equip
ment and well has 1t earned the dis
tinction. II you were to ask me what
piece of added equipment is the most
important, l believe | should give the
palm to the power tire pump. The rea
son ! say this is that the tire pump
Is not only convenience, but it con-
tributes very materially to cutting
down the biggest bill that the car
owner has to pay in the course of the
year. Many makes of cars still lack
this equipment. In fact, the cheaper
cars. which are sold in the greatest
quantities, do not have power pumps,
so l am going to describe this impor-
tant accessory for the benefit of the
man who wants to install a pump on
his car, as well as for the man who
has one and merely wants to learn all
about 1t and how to care for it.
UNDERlNFLATION SERIOUS.
In the first place let us note that
underinflation is the most serious
cause of tire destruction in this coun-
try. The man who has to go through
the back breaking operation of pump
ing UP by hand, puts it off Just as
long as he can. When he can do the
work by engine power he is not likely
to neglect bringing up the pressure to
the proper poundage That is why !
say that the power pump helps cut
down the biggest bill the car owner has
to pay, the tire bill.
Let me caution my readers to be-
gin with, that buying a cheap and in
ferior pump is the worst possible
economy. 1t will be out of order so
much that the hand pump might just
as well be used in the first place. And |
even If it does hold together, it will be |
so noisy that it will sound like a
threshing machine in full swing. In |
these cheap pumps there is usually end |
play in the crank shaft from the very
beginning. Sometimes this trouble de-
velops in really good pump, but you
will get long service from them be-
fore you have any difficulties.
TYPES OF PUMPS
There are four distinct types of tire
pumps in the market at the present |
time. The most popular type is the
single cylinder, piston pump, with
crankshaft and connecting rods Just
like the engine in miniature The next
type comprises sort of flexible
leather piston in the shape of a dia-
phragm. A third type is driven by en-
CINE compression, instead of mechani-
cally, while the fourth is driven from
the front end Of the crankshaft
The mechanically operated pumps
are usually driven from the transmits
sion shaft, which location removes the
pump from the engine compartment
and incloses the drive, giving quiet OPP
GRAFTON and plentiful fabrication. The
question of fabrication is a very i'm
portant one in tire pumps, as they
