New Chalmers High-speed
ENGINEERHS TO GET
Department Secures Machine Through
Efforts of Men on Company's
The bill of lading has just been re-
ceived by the Automobile Engineering
Department from the Chalmers Motor
Car Company of Detroit for one of
their latest complete motors, model
35. This presentation to the depart-
ment has been made through the ef-
forts of Mr. Malcolm McCormick and
Mr. Paul Smith, Vice-President of the
selling division of the Chalmers.
The motor is the same as the one
used in their master six, running at
3400 R. P. M. and delivering 35 horse-
power at 2400 R. P. M. It is the first
extremely high speed motor presented
to the laboratory and will thus make
a very valuable addition to the al-
ready complete laboratory equipment.
The remarkable co-operation of au-
tomobile manufacturers with the de-
partment is well indicated by the fact
-that equipment has been presented for
use in laboratory courses by the fol-
lowing :automobile manufacturers:
Studebaker--Complete show chassis
and engine section to show interior.

WORTH WHILE FACS
A recent article in Popular Mechan-
ics exploits the invention of an electric
windshield cleaner. A coil of wire,
oval in shape, and perhaps six or
eight inches in the largest inside di-
mension, is clamped against the glass
of the windshield by means of springs
attached to the frame. Current from
a storage battery is sent through the
coil, the latter having enough resis-
tance to produce considerable heat.
This heat is said to be sufficient to
melt frost and snow from the shield,
thus permitting a clear view ahead
under the most adverse conditions.
EELEPHONE LINE FOR SAFETY
On a steep winding grade near Hood
River, Oregon, where the road is too
narrow to permit the passing of two
automobiles, a telephone line has been
installed to enable the motorist to as-
certain whether or not the road is
clear. Before the system was installed
there were frequent tie-ups caused by
the meeting of two cars on the hill,
which invariably caused the up-bound
machine to back down the perilous
DESIGN AUTO LIGHT DIFFUSER
A light diffuser designed to be car-
ried on the windshield of an automo-
bile is the latest means of counteract-
ing the glare from the headlight of
an approaching car, as Al as pre-
venting the eye strain caused by the
glare of the sunlight on the roadway.
The device consists of a square of
special amber glass mounted in a
framework of brass rods, and so ar-
ranged that the glass can be placed
in any position to suit the line of
vision of the driver.
CLASSIFY ALL ROAD SURFACES
It is not generally known how many
different kinds of road surfaces there
are in use in this country. The Unit-
ed States department of agriculture
has classified them under the fol-
lowing heads: Brick paved, concrete,

IIMPOlITA NT TO BUYI N PUITA(

The Engine and Transmission divi-
sion, organized for the consideration
of all questions of design and stan-
dardization of the motor, transmission,
clutch, and rear azle units, has un-
dertaken the collection and interpreta-
tion of motor characteristic curves,
and in connection with this work has
given much consideration to the ques-
tion of Horse Power rating. At the
present time many manufacturers rate
their mtors by the so-called A. L. A.
M. or S. A. E. formula: Horse Power
bore x bore x number of cylinders
divided by 2.5.
This formula gives an approximate
value of the horse power of amotor
at 1,000 feet per minute piston speed,
which for a motor of 6-inch stroke
would be at 1,000 R. P. M. It thus
appears that for a motor, this formu-
la gives the approximate maximum
horse power output at a motor speed
which is not far from average road
While this figure is important and
desirable, the maximum horse power
output of a motor at high speed is also
of great interest and importance to
both engineer and operator. Some
manufacturers, indeed, neglect the
S. A. E. rating entirely and proceed
to rate their motors by this maximum
figure. 'thus it is that the engineer
and the prospective automobile owner
is' confronted with a most disconcert-
ing mix-up in rating which makes a
reliable comparative study difficult,
if not impossible.
The public and the automobile en-
gineer is taking a decided interest in
this matter. All recognize that the
present state of affairs is far from
satisfactory. In this connection, Pro-
fessor Fishleigh, as chairman of the
Engine and Transmission committee,
has suggested a simple, yet adequate

TESTS SHOW LOSS OF ENERGY
W. H. FAUST,
1421 Hill St.
The automobile squad is at present
engaged in determining by the most
refined laboratory methods just what
becomes of the energy which is fur-
nished to the motor in the gasoline.
Although several investigators have
accounted for causes responsible for
a small portion of the total energy
used up, no tests as com-
plete as those carried out
by the local squad have
as yet been undertaken by

the motor is partially re-
covered in ubrake horse
power, while the remain-
der is consumed by fric-
tional horse power, ex-
haust, cooling water, and
some energy, in the form
r of heat, is carried by the
air draft past the motor.
The squad is actu-
ally measuring all these
quantities, and from the results
of their tests they are determining a
complete heat balance. The tests have
been carried out on a very elaborate
setup, the only one of its kind in the
The preliminary runs have just been
completed and indications point to an
accuracy of 95 to 97%, a remarkable
figure for automobile work of this
magnitude. Approximate figures for
two preliminary runs, the first with
motor developing 4.5 horse power, the
second developing 16 horse power,
both at 640 R. P. M., are as follows.
The motor tested is a Hudson six-54.

Car-Body Srings Need Care
Many motorists do not give
the attention to the car-body
springs necessary to keep them
in good condition. These springs
need oil the same as any other
bearing on the car. Many cheap
devices are on the market for
opening the springs so that oil
or graphite can be inserted.
This attention should be given at
least every six months if the
car is used regularly.
