Drafting Dan

Drafting Dan is Aladdin’s powered semi-automatic drawing machine, a keyboard-operated alternative to drafting by hand whose design becomes an uncanny signature of Dan Davis’s engineering judgment. First encountered as a commercial product during Dan’s search for work, it later leads him through patent records to the discovery that he himself is its inventor; when he returns to 1970, he builds it before rebuilding Flexible Frank as Protean Pete.

Identity and Design

Drafting Dan mechanizes the placement of lines and curves on an easel. Dan imagines it as bearing the same relation to a drawing board and T-square that a typewriter bears to handwriting: instead of constructing every mark by hand, the draftsman can position straight lines or curves by punching keys. He has worked out this design in his head, but the machine he encounters is not an idea stolen from him. His own imagined drafting machine never existed outside his thoughts; someone else independently developed the same idea.

The machine is made by Aladdin, the firm that also makes Eager Beaver. Its powered, semi-automatic operation belongs to a changed technical world: Dan has seen pictures of such drafting machines but has never worked at one. He suspects that he could learn to use one quickly, and his first encounter will make that confidence concrete.

The Encounter and Recognition

Seeking even a subprofessional position so that he can absorb current engineering practice, Dan hopes to get work as a junior draftsman. Rather than arrive as a job applicant, he goes to Aladdin’s salesrooms posing as a prospective customer. He has spent some of his savings on a better suit and a secondhand briefcase, which he stuffs with newspapers, and asks for a demonstration of Drafting Dan.

Standing beside the machine produces an unsettling sense of recognition. Its design follows the course Dan believes he would have taken had he been able to develop his idea instead of being kidnapped into the Long Sleep. He struggles to explain why the resemblance feels so exact: engineering, in his account, is not simply science but an art, with a wide range of possible solutions. A designer’s choices leave a recognizable personal mark, just as an artist’s choices do in a painting. Drafting Dan carries Dan’s working style so strongly that he briefly wonders whether telepathy might explain the likeness.

The encounter is not merely visual. When the salesman demonstrates the machine, Dan finds it immediately natural to operate. In ten minutes he can use it better than the salesman. He continues making pictures with it before drawing the demonstration to a close, obtaining its list price, discounts, and service arrangements, then leaving without signing a purchase agreement. His fluency makes the resemblance physical as well as intellectual: the machine fits his hands and habits as though it were his own work.

Patents and the Inventor

Dan records the number of Drafting Dan’s first patent and is not surprised to find that it dates to 1970. At first, the patent offers a mystery rather than an answer. He considers whether the inventor might have been one of his teachers or a former colleague, and hopes that the person, if still alive, could become an engineering mentor.

His search for the original patents on both Eager Beaver and Drafting Dan grows out of a separate question about Flexible Frank. Dan has suspected that the original Eager Beaver might have been another name for Flexible Frank, but Drafting Dan’s strikingly similar design makes him consider another possibility: one unknown inventor could have independently developed equivalents of both machines. Both patents were taken out in the same year, and both were held, or had been held until expiration, by Aladdin. To investigate, Dan writes to the patent office, learns that records for expired patents are kept at the National Archives in Carlsbad Caverns, and ultimately requests the descriptions, claims, drawings, and histories of both patents.

When he turns to the first Drafting Dan patent, numbered 4,307,910, the drawings intensify his recognition. He admires the economical linkages and the use of circuits to keep moving parts to a minimum. The design even uses an electric typewriter for its keyboard chassis, crediting an IBM patent series: to Dan, this is good engineering because it uses an available component rather than reinventing one. The papers identify the inventor as D. B. Davis. The unknown designer he hoped to meet is Dan Davis himself.

Return to 1970

The patent discovery helps establish Drafting Dan as one of Dan’s own inventions, not simply a machine that happens to resemble an abandoned idea. In 1970, with limited money and no time to waste on the old compass-and-T-square method, he builds Drafting Dan before rebuilding Flexible Frank. The sequence is practical: he needs the drawing machine to make the work of design less tedious and more efficient.

His return to the machine also connects the patent record to the next generation of his engineering work. He rebuilds Flexible Frank as Protean Pete, an all-purpose automaton whose capabilities depend on properly instructed Thorsen tubes. Dan expects later descendants of this adaptable machine to evolve into specialized devices, but initially wants the patent claims to be as broad as possible. Drafting Dan therefore has a double place in his career: it is a commercial product he recognizes as an expression of his own design mind, and a working invention he constructs again in the year named by its patent.

Narrative Significance

Drafting Dan turns an ordinary demonstration into an encounter with the consequences of Dan’s displacement in time. He sees a machine that appears to have anticipated his unrealized design, then follows that resemblance backward through a patent trail until it leads to his own name. The surprise does not rest on the claim that his idea was stolen: Dan explicitly distinguishes the machine from Flexible Frank, which he believes was stolen, because Drafting Dan existed only in his head before its independent development.

The episode makes engineering style function as a form of recognition. Dan reads identity in choices of linkage, circuitry, components, and operation—the same kind of evidence that lets him identify an artist by brushwork. The patent supplies the documentary answer, but the recognition comes first through design. When Dan later builds Drafting Dan in 1970, the machine is no longer an uncanny product encountered in someone else’s showroom. It has become the practical instrument through which he resumes the engineering work that time interrupted.
