Building the Sky Racer
“What will you do, if, after
you have your little monoplane all constructed, and
get ready to race, you find that some one else has
one exactly like it at the meet?” asked Ned
Newton one day, when he and Tom were out in the big
workshop, talking things over. “What will
you do, Tom?”
“I don’t see that there
is anything I can do. I’ll go on to the
meet, of course, and trust to some improvements I
have since brought out, and to what I know about aeroplanes,
to help me win the race. I’ll know, too,
who stole my plans.”
“But it will be too late, then.”
“Yes, too late, perhaps, to
stop them from using the drawings, hot not too late
to punish them for the theft. It’s a great
mystery, and I’ll be on the anxious seat all
the while. But it can’t be helped.”
“When are you going to start work on the sky
racer?”
“Pretty soon, now. I’ve
got another set of plans made, and I’ve fixed
them so that if they are stolen it won’t do any
one any good.”
“How’s that?”
“I’ve put in a whole lot
of wrong figures and measurements, and scores of lines
and curves that mean nothing. I have marked the
right figures and lines by a secret mark, and when
I work on them I’ll use only the proper ones.
But any one else wouldn’t know this. Oh,
I’ll fool ’em this time!”
“I hope you do. Well, when
you get the machine done I’d like to ride in
it. Will it carry two, as your Butterfly does?”
“Yes, only it will be much different;
and, of course, it will go much faster. I’ll
give you a ride, all right, Ned. Well, now I must
get busy and see what material I need for what I hope
will prove to be the speediest aeroplane in the world.”
“That’s going some!
I must be leaving now. Don’t forget your
promise. I saw Mary Nestor on my way over here.
She was asking for you. She said you must be
very busy, for she hadn’t seen you in some time.”
“Um!” was all Tom answered,
but by the blush that mounted to his face it was evident
that he was more interested in Mary Nestor than his
mere exclamation indicated.
When Ned had gone Tom got out pencil
and paper, and was busily engaged in making some intricate
calculations. He drew odd little sketches on
the margin of the sheet, and then wrote out a list
of the things he would need to construct the new aeroplane.
This finished, he went to Mr. Jackson,
the engineer, and asked him to get the various things
together, and to have them put in the special shop
where Tom did most of his work.
“I want to get the machine together
as soon as I can,” he remarked to the engineer,
“for it will need to be given a good tryout before
I enter in the race, and I may find that I’ll
have to make several changes in it.”
Mr. Jackson promised to attend to
the matter right away, and then Tom went in to talk
to his father about the motor that was to whirl the
propeller of the new air craft.
Mr. Swift had improved very much in
the past few days, and though Dr. Gladby said he was
far from being well, the physician declared there was
no reason why he should not do some inventive work.
He and Tom were deep in an argument
of gasoline motors, discussing the best manner of
attaching the fins to the cylinders to make them air-cooled,
when a voice sounded outside, the voice of Eradicate:
“Heah! Whar yo’ goin’?”
demanded the colored man. “Whar yo’
goin’?”
“Somebody’s out in the
garden!” exclaimed Tom, jumping up suddenly.
“Perhaps it’s the same
person who took the plans!” suggested Mr. Swift.
“Hold on, dere!” yelled Eradicate again.
Then a voice replied:
“Bless my insurance policy!
What’s the matter? Have there been burglars
around? Why all these precautions? Bless
my steam heater! Don’t you know me?”
“Mr. Damon!” cried Tom,
a look of pleasure coming over his face. “Mr.
Damon is coming!”
“So I should judge,” responded
Mr. Swift, with a smile. “I wonder why
Eradicate didn’t recognize him?”
They learned why a moment later, for
on looking from the library window, Tom saw the colored
man coming up the walk behind a well-dressed gentleman.
“Why, mah goodness! It’s
Mr. Damon!” exclaimed Eradicate. “I
didn’t know yo’, sah, wif dem whiskers
on! I didn’t, fo’ a fac’!”
“Bless my razor! I suppose
it does make a difference,” said the eccentric
man. “Yes, my wife thought I’d look
better, and more sedate, with a beard, so I grew one
to please her. But I don’t like it.
A beard is too warm this kind of weather; eh, Tom?”
And Mr. Damon waved his hand to the young inventor
and his father, who stood in the low windows of the
library. “Entirely too warm, bless my finger-nails,
yes!”
“I agree with you!” exclaimed
Tom. “Come in! We’re glad to
see you!”
“I called to see if you aren’t
going on another trip to the North Pole, or somewhere
in the Arctic regions,” went on Mr. Damon.
“Why?” inquired Tom.
“Why, then this heavy beard
of mine would come in handy. It would keep my
throat and chin warm.” And Mr. Damon ran
his hands through his luxuriant whiskers.
“No more northern trips right
away,” said Tom. “I’m about
to build a speedy monoplane, to take part in the big
meet at Eagle Park.”
“Oh, yes, I heard about the
meet,” said Mr. Damon. “I’d
like to be in that.”
“Well, I’m building a
machine that will carry two,” went on Tom, “and
if you think you can stand a speed of a hundred miles
an hour, or better, I’ll let you come with me.
There are some races where a passenger is allowed.”
“Have you got a razor?” asked Mr. Damon
suddenly.
“What for?” inquired Mr.
Swift, wondering what the eccentric man was going
to do.
“Why, bless my shaving soap!
I’m going to cut off my beard. If I go in
a monoplane at a hundred miles an hour I don’t
want to make any more resistance to the wind than
possible, and my whiskers would certainly hold back
Tom’s machine. Where’s a razor?
I’m going to shave at once. My wife won’t
mind when I tell her what it’s for. Lend
me a razor, please, Tom.”
“Oh, there’s plenty of
time,” explained the lad, with a laugh.
“The race doesn’t take place for over
two months. But when it does, I think you would
be better off without a beard.”
“I know it,” said Mr.
Damon simply. “I’ll shave before we
enter the contest, Tom. But now tell me all about
it.”
Tom did so, relating the story of
the theft of the plans. Mr. Damon was for having
Andy arrested at once, but Mr. Swift and his son pointed
out that they had no evidence against him.
“All we can do,” said
the young inventor, “is to keep watch on him,
and see if he is building another aeroplane.
He has all the facilities, and he may attempt to get
ahead of me. If he enters a sky craft at the meet
I’ll be pretty sure that he has made it from
my stolen plans.”
“Bless my wing tips!”
cried Mr. Damon. “But can’t we do
anything to stop him?”
“I’m afraid not,”
answered Tom; and then he showed Mr. Damon his re-drawn
plans, and told in detail of how he intended to construct
the new aeroplane.
The eccentric man remained as the
guest of the Swift family that night, departing for
his home the next day, and promising to be on hand
as soon as Tom was ready to test his new craft, which
would he in about a month.
As the days passed, Tom, with the
help of his father, whose health was slightly better,
and with the aid of Mr. Jackson, began work on the
speedy little sky racer.
As you boys are all more or less familiar
with aeroplanes, we will not devote much space to
the description of the new one Tom Swift made.
We can describe it in general terms, but there were
some features of it which Tom kept a secret from all
save his father.
Suffice it to say that Tom had decided
to build a small air craft of the single-wing type,
known as the monoplane. It was to be a cross between
the Bleriot and the Antoinette, with the general features
of both, but with many changes or improvements.
The wings were shaped somewhat like
those of a humming-bird, which, as is well known,
can, at times, vibrate its wings with such velocity
that the most rapid camera lens cannot quite catch.
And when it is known that a bullet
in flight has been successfully photographed, the
speed of the wings of the humming-bird can be better
appreciated.
The writer has seen a friend, with
a very rapid camera, which was used to snap automobiles
in flight, attempt to take a picture of a humming-bird.
He got the picture, all right, but the plate was blurred,
showing that the wings had moved faster than the lens
could throw them on the sensitive plate.
Not that Tom intended the wings of
his monoplane to vibrate, but he adopted that style
as being the best adapted to allow of rapid flight
through the air; and the young inventor had determined
that he would clip many minutes from the best record
yet made.
The body of his craft, between the
forward wings and the rear ones, where the rudders
were located, was shaped like a cigar, with side wings
somewhat like the fin keels of the ocean liner to prevent
a rolling motion. In addition, Tom had an ingenious
device to automatically adapt his monoplane to sudden
currents of air that might overturn it, and this device
was one of the points which he kept secret.
The motor, which was air-cooled, was
located forward, and was just above the heads of the
operator and the passenger who sat beside him.
The single propeller, which was ten feet in diameter,
gave a minimum thrust of one thousand pounds at two
thousand revolutions per minute.
This was one feature wherein Tom’s
craft differed from others. The usual aeroplane
propeller is eight feet in diameter, and gives from
four to five hundred pounds thrust at about one thousand
revolutions per minute, so it can be readily seen
wherein Tom had an advantage.
“But I’m building this
for speed,” he said to Mr. Jackson, “and
I’m going to get it! We’ll make a
hundred miles an hour without trouble.”
“I believe you,” replied
the engineer. “The motor you and your father
have made is a wonder for lightness and power.”
In fact, the whole monoplane was so
light and frail as to give one the idea of a rather
large model, instead of a real craft, intended for
service. But a careful inspection showed the great
strength it had, for it was braced and guyed in a
new way, and was as rigid as a steel-trussed bridge.
“What are you going to call
her?” asked Mr. Jackson, about two weeks after
they had started work on the craft, and when it had
begun to assume shape and form.
“I’m going to name her
the Humming-Bird,” replied Tom. “She’s
little, but oh, my!”
“And I guess she’ll bring
home the prize,” added the engineer.
And as the days went by, and Tom,
his father and Mr. Jackson continued to work on the
speedy craft, this hope grew in the heart of the young
inventor. But he could not rid himself of worry
as to the fate of the plans that had disappeared.
Who had them? Was some one making a machine like
his own from them? Tom wished he knew.
