Chapter 307: Cargo One Part 2

At seven o’clock the following morning, the massive sliding wooden doors of Experimental Workshop Number Two were locked from the inside.

A continuous six-foot roll of heavy vellum drafting paper was pinned across the wide mahogany layout tables. Two brass desk lamps illuminated the clean surface, casting a warm pool of light over pencils, steel rules, beam compasses, and mechanical calculators.

Ernest picked up a stick of soft sketching charcoal. At the top of the vellum, he wrote:

TEUCHER COMMERCIAL MOTOR PLATFORM

Hollen, who was pouring two mugs of strong tea from an iron kettle on the heating stove, stopped and frowned at the title.

"That is a dreadful, bureaucratic name," Hollen said bluntly, setting a mug on the table.

"It is an accurate, functional description," Ernest countered.

"It sounds like a government agricultural report. Call it what it actually is."

Ernest erased the charcoal with the heel of his hand, blowing away the black dust. He wrote:

TEUCHER MOTOR TRUCK

Hollen took a sip of his tea and nodded. "Better. Now give it a designation."

Ernest touched the charcoal to the paper and began to write: MODEL T—

He stopped dead.

The charcoal hovered a millimeter above the surface.

A sudden, sharp chill of historical deja vu rippled down his spine. His mind flashed back to Earth: black lacquer, planetary transmissions, assembly lines spanning millions of units, and the legendary name that had defined the twentieth century.

Ernest pressed down hard, violently scribbling over the letter T with thick, black charcoal strokes until the vellum nearly tore beneath the pressure.

Hollen blinked, staring at the sudden explosion of black ink. "Are you having an apoplectic stroke?"

Ernest exhaled slowly, resting his knuckles against the table. "No. I am perfectly well."

"You looked like that letter offended your ancestors."

"It was an inappropriate designation," Ernest said, keeping his voice carefully neutral.

He moved the charcoal down to the next line and wrote with steady, deliberate strokes:

TEUCHER CARGO ONE

Hollen tilted his head, studying the lettering. "Cargo One. Simple. Honest. It sounds like a freight wagon that doesn’t care about looking pretty."

"A commercial vehicle should never care about looking pretty," Ernest stated. "It has only one moral duty: to earn more revenue for its owner than it consumes in fuel and maintenance."

They began with the core engineering constraint: payload capacity.

Ernest wrote: RATED PAYLOAD CAPACITY: 2,000 KG (TWO METRIC TONNES).

Hollen immediately shook his head, planting his thick finger on the number. "Too low, Ernest. You just saw that brewery dray hauling three tonnes of ale."

"Two tonnes covers eighty-five percent of all urban freight deliveries," Ernest pointed out. "If we design the baseline machine for four tonnes, the chassis will be too heavy, the fuel consumption will be ruinous for light merchants, and the tire wear will be unmanageable on gravel."

"You don’t understand merchants," Hollen retorted, leaning over the table. "If you put a brass plate on this vehicle that says ’Rated Capacity: 2,000 Kilograms,’ the very first thing a Helmarte timber merchant will do is drop two thousand eight hundred kilograms of wet oak logs onto the bed, kick the rear tires, and drive it straight over a broken stone gutter."

Ernest frowned. "Overloading a vehicle voids the manufacturer’s operational warranty."

Hollen laughed out loud. "A timber merchant doesn’t care about your warranty! He cares about making two delivery runs instead of three! If the rear frame snaps like a carrot, he won’t blame his own greed; he will stand in the town square and shout that Baron Teucher builds fragile iron toys!"

Ernest considered the harsh reality of human nature. Hollen, as usual, had a far better grasp of how ordinary men abused machinery.

Ernest adjusted the specifications:

RATED COMMERCIAL PAYLOAD: 2,000 KG

STRUCTURAL RESERVE MARGIN: 3,200 KG STATIC OVERLOAD CAPACITY

"Now you’re thinking like a blacksmith," Hollen grunted approvingly.

Next came the foundation: the chassis.

The standard Model One passenger car utilized a lightweight channel-steel frame with thin crossmembers, designed to flex slightly to absorb road shock.

For Cargo One, that design philosophy was completely discarded.

Ernest drew two massive, parallel frame rails running the full length of the vehicle.

"Cold-pressed structural alloy steel," Ernest explained, sketching the cross-section. "Six inches deep through the central load-bearing span, with a three-inch flange. Five heavy tubular crossmembers hot-riveted into position, reinforced with diagonal gusset plates at the rear spring hangers."

Hollen whistled softly. "That frame alone will weigh six hundred pounds."

"It will weigh six hundred and fifty," Ernest corrected him. "And it will not twist when one rear wheel drops into an eight-inch ditch while carrying two tons of flour."

For the suspension, they designed long, heavy-duty semi-elliptic leaf spring packs. The rear cluster featured eleven individual manganese-steel leaves, backed by an auxiliary ’helper’ spring mounted directly above the main pack. Under an empty load, the truck would ride solely on the soft primary springs; when loaded with heavy freight, the chassis would settle two inches, engaging the heavy helper leaves to absorb massive cargo weight.

Then came the powertrain.

Ernest’s hand drifted toward the corner of the table where he had begun sketching a four-cylinder monoblock engine.

Hollen saw the four circles and immediately slapped his hand over the paper.

"No," Hollen said firmly.

Ernest looked up, annoyed. "A four-cylinder powerplant provides overlapping power strokes, significantly reducing torsional vibration through the drivetrain."

"It also requires four cast-iron pistons, four forged connecting rods, eight precision-ground poppet valves, and twice the machining time on the boring mills," Hollen fired back. "Plant Two’s foundry is already running at capacity casting two-cylinder blocks for the Model One. If you introduce an entirely new four-cylinder engine today, you will delay this vehicle by fourteen months."

Ernest stared at the blueprint, his engineering idealism warring with manufacturing reality.

Hollen was right. A brilliant design that could not be manufactured on existing tooling was useless.

"An enlarged two-cylinder industrial engine," Ernest conceded, setting the four-cylinder sketch aside. "We increase the cylinder bore from four inches to four-and-seven-eighths. We extend the stroke to five-and-a-half inches. We lower the maximum operating speed from eighteen hundred revolutions per minute down to twelve hundred."

Hollen’s eyes narrowed as he did the mental arithmetic. "A heavy, slow-turning displacement engine."

"Exactly," Ernest said, sketching the new block. "Large combustion chambers, massive cast-iron flywheel to store rotational inertia, and heavy babbitt-lined main bearings. It will produce only sixteen horsepower, but it will deliver massive low-end torque right off idle. It will pull two tonnes out of a muddy coal yard without stalling."

"And it can run on low-grade, heavy kerosene fractions if refined gasoline is unavailable," Hollen added.

"Yes. That will significantly lower daily fuel costs for rural operators."

The transmission sparked their first heated argument of the day.

Ernest wanted a simple three-speed sliding-gear transmission to keep manufacturing costs down.

Hollen demanded four speeds.

"Three forward ratios are entirely sufficient for city delivery," Ernest argued, drawing gear teeth.

"Three ratios mean the gap between first and second gear is an absolute chasm!" Hollen shouted, slamming his teacup down. "If a driver is hauling two tons of stone up the western heights, first gear will be too slow, but the moment he shifts into second, the engine will bog down, choke on its own fuel, and die halfway up the slope!"

"A four-speed gearbox adds twelve precision-ground gears, two selector forks, and extends the transmission casing by four inches!"

"And a three-speed gearbox leaves a loaded truck stranded in front of thirty angry carriage drivers while the clutch burns to ashes!" Hollen bellowed.

They argued back and forth for forty minutes, trading gear ratio calculations, torque curves, and mechanical leverage equations across the vellum sheet.

By noon, the layout bore the definitive mark of Hollen’s victory:

TRANSMISSION: 4-SPEED SLIDING MESH + REVERSE

First Gear (Crawl): 4.8:1 (For starting on 15% gradients under maximum load)

Second Gear (Low Work): 2.9:1 (For city traffic and heavy hill climbs)

Third Gear (Direct Urban): 1.6:1 (For 12–15 mph arterial transit)

Fourth Gear (Overdrive Cruise): 1.0:1 (For 22 mph unladen highway travel)

"Four speeds," Ernest murmured reluctantly, circling the housing.

Hollen smirked. "You’ll thank me the first time you drive it up a hill."

Final drive came next.

The Model One passenger car utilized exposed steel roller chains driving the rear wheels. It was simple, light, and easy to repair.

For a heavy two-tonne truck, however, exposed chains were an operational disaster. Grit, mud, and road stones would grind the sprockets to pieces within five hundred miles of gravel driving.

Ernest drew a thick, enclosed steel tube extending from the rear of the transmission to a massive cast-steel rear axle housing.

"Enclosed propeller shaft," Ernest announced. "A heavy-duty bevel-gear differential running in a continuous oil bath. Fully floating rear axle shafts, supported by dual tapered roller bearings at the wheel hubs."

Hollen leaned over the drawing, his expression growing deeply serious. "A full-floating axle? That means the drive axles carry no vehicle weight whatsoever; they only transmit rotational torque."

"Precisely," Ernest said. "The entire two-tonne cargo load is carried directly by the heavy cast-steel axle housing and the wheel bearings. If a driver snaps an axle shaft on a rough road, the wheel will not fall off. The vehicle remains standing, and the mechanic can pull the broken shaft from the hub without jacking up the chassis."

Hollen nodded with profound professional respect. "That is proper industrial design, Ernest. No compromises on safety."

Braking, however, proved to be their greatest mathematical challenge.

A passenger car weighing eight hundred kilograms traveling at twenty miles per hour carried relatively modest kinetic energy.

A fully loaded Cargo One, scaling nearly four thousand kilograms with cargo, carried enough momentum to demolish a brick wall.

Ernest calculated the friction area required. He shook his head in dismay.

"Standard external-contracting brake bands will burn out in twenty miles of hilly terrain," Ernest said.

"They fade completely when wet," Hollen added.

Ernest redesigned the rear brake drums. He expanded their diameter to a massive sixteen inches, with heavy cast-iron internal expanding shoes three inches wide.

To ensure complete redundancy, he split the braking system into two entirely independent mechanical circuits:

Service Brakes: Foot pedal actuating internal expanding shoes on all four wheels via balanced steel cables.

Emergency/Parking Brake: A heavy hand lever linked directly to a powerful external contracting band clamping around an eight-inch steel drum mounted directly behind the transmission on the primary driveshaft.

"A transmission brake?" Hollen asked, raising his eyebrows.

"If the rear brake linkages snap or the wheel drums overheat, the transmission brake applies mechanical stopping force directly through the differential gears," Ernest explained. "It gives the driver a completely independent mechanical anchor."

By late afternoon, the mechanical layout of the chassis was fully resolved.

Ernest and Hollen stood back from the table, stretching their stiff backs.

The vellum sheet was covered in crisp, black ink:

SPECIFICATION: TEUCHER CARGO ONE (BASELINE CHASSIS)

Frame: Cold-pressed channel alloy steel ladder chassis.

Engine: Two-cylinder industrial low-speed engine (16 HP @ 1,200 RPM).

Drivetrain: Heavy-duty 4-speed manual; enclosed shaft drive; full-floating rear axle.

Suspension: Heavy semi-elliptic leaf springs with progressive overload helpers.

Brakes: 4-wheel internal expanding drums + independent transmission parking brake.

Gross Vehicle Weight Rating: 4,200 kg (Chassis + Body + 2,000 kg Payload).

Top Speed: 22 mph unladen; 14–16 mph fully loaded.

Hollen walked along the length of the blueprint, tapping his finger against the front section.

"You forgot something rather important, Ernest," Hollen said dryly.

Ernest looked at the blueprint. "The steering geometry is fully defined. The cooling radiator has three times the core surface of the Model One. The fuel tank holds fifteen gallons—"

"Where does the driver sit?" Hollen interrupted.

Ernest paused, looking down at the bare steel frame rails flanking the engine.

"I was planning to mount a simple wooden bench behind the firewall," Ernest muttered defensively.

Hollen groaned, rubbing his temples. "A wooden bench. You are asking a working drayman to spend twelve hours a day bouncing over frozen cobblestones in the middle of a November blizzard, and you want him to sit on a bare wooden board?"

Ernest remembered Eleanor’s sharp critique of early automobile prototypes: Men design machines for other men to suffer in.

"We will build a proper enclosed weather cab," Ernest said, quickly picking up his pencil.

He drew a sturdy timber-and-sheet-steel cabin.

He added a deeply padded bench seat supported by spiral steel springs. He integrated a flat laminated-glass windscreen, a curved sheet-steel roof covered in waterproof canvas, and heavy roll-up leather side curtains with celluloid viewports.

To ease the physical labor of the driver, he added a wide iron running board and a heavy brass grab handle mounted to the door pillar.

Finally, Ernest addressed the cargo area.

Behind the cab, the long steel frame rails extended nine feet toward the rear bumper.

The space was completely blank.

"Are you not drawing the cargo box?" Hollen asked.

"No," Ernest said with a small smile.

"Why not?"

"Because one single cargo body cannot serve an entire industrial economy," Ernest explained, tapping the blueprint. "The brewery requires high stake-sides with barrel tie-down rings. The textile mill requires an enclosed, lockable wooden van body. The builder requires a three-way dropside flatbed. The municipal sanitation department requires an iron tipping hopper."

Hollen’s eyes widened. "A standardized chassis mounting interface."

"Exactly," Ernest said. "We establish four standardized mounting bolsters along the frame rails. We publish the exact dimensional blueprints to every independent carriage builder and carpentry workshop in the kingdom. We sell the rolling chassis and cab; the local carriage trade builds the specialized cargo body to suit their individual customer’s trade."

Hollen let out a long whistle. "Arthur is going to weep with joy. That brings the entire carriage manufacturing industry onto our side instead of trying to ban us through municipal ordinances."

Just then, the heavy workshop door rattled.

A key turned in the lock, and Arthur Pendelton walked in, carrying a leather portfolio and brushing rain from his bowler hat.

He stopped, looking at the massive blueprint spread across the table.

Arthur looked from the six-foot drawing to Hollen, and finally settled his sharp gaze onto Ernest.

"Tell me that is not another pleasure carriage," Arthur said, pointing his umbrella at the paper.

"It is not," Ernest replied.

Arthur leaned over the table, his eyes scanning the figures: 2,000 kg payload... 16 horsepower... 4-speed transmission... enclosed shaft drive.

Arthur looked up, his expression completely transformed.

The perpetual commercial skepticism had vanished from his eyes, replaced by the razor-sharp focus of an industrial financier who had just spotted an empire.

"How soon can we build a prototype?" Arthur asked quietly.

"Three weeks for the frame and drivetrain," Hollen answered.

Arthur tapped the portfolio under his arm. "Because I have three commercial transport syndicates, two municipal delivery firms, and the entire board of the Royal Postal Ministry waiting for an answer. The passenger car was an aristocratic novelty, gentlemen. But this..."

Arthur smiled, a cold, brilliant, commercial smile.

"...this is the machine that will carry the entire economy of this kingdom."
