Technology in the arts

It was known to all of my friends where I was raised at the out­skirts of San Anto­nio, Texas.

That whine … six hor­i­zon­tally opposed cylin­ders (“boxer” the Ger­mans call it) mov­ing back and forth at exceed­ingly high rates of accel­er­a­tion. Intake, com­pres­sion, igni­tion, exhaust over and over again all in the ser­vice of moti­vat­ing a sculp­ture on four wheels to move in a sin­gle direc­tion at high velocity.

A friend’s older brother drove the Amer­i­can dream machine — a Dodge Super Bee. A clas­sic V-8 sound ema­nat­ing from a car whose run­ning gear hadn’t changed much in 20 or more years. The other kids thought it was pretty cool.

And of course there was the occa­sional sound of a pass­ing vin­tage British sports car or the week-day rit­ual of our neigh­bor — “Clark Kent” I thought to myself — who came home from work in a Corvette wear­ing his nice busi­ness suit only to emerge from his garage a half-hour later on his Harley Sport­ster wear­ing his Ban­di­tos vest and tat­tered blue jeans. In those days the Harley sound was unmis­take­able. “Thumpa-da-thumpa-da …”

But to a kid accus­tomed to the game of iden­ti­fy­ing mil­i­tary air­craft fly­ing over­head by the sound they made there was no sound quite so sweet as that made by a brand new 1967 Porsche 911S  (“dri­ven as it as meant to be” as my father would say) as it screamed past our flag foot­ball game return­ing my father home from work. The cir­cle of friends in the sports car world he inhab­ited while work­ing for Porsche Cars South­west helped intro­duced me to the idea that art and engi­neer­ing were next of kin.

So it was nat­ural for me to find fas­ci­na­tion in the world of automa­tons. There were count­less exam­ples in the odd muse­ums and wacky col­lec­tions we vis­ited. Whirring gears, creak­ing mech­a­nisms — crude but mes­mer­iz­ing attempts to mimic the nat­ural move­ments of liv­ing crea­tures. That fas­ci­na­tion for the con­nec­tion between tech­nol­ogy and art, mechan­ics and aes­thet­ics — heck, even sci­ence and silli­ness has informed my inter­ests ever since.

So when I first stum­bled upon the inter­est­ing story of the pile of brass gears, cams and assorted mechan­i­cal body parts “dumped on the steps” of the Franklin Insti­tute in 1928 and only recently appre­ci­ated for what they were I had to know more. So now the Insti­tute has put together a more detailed account of the adven­ture on their web­site.

"Draughtsman-Writer" by Henri Maillardet

Draughtsman-Writer” by Henri Maillardet

The Draughtsman-Writer belongs to the golden age of automa­tons when tech­nol­ogy was at stage where the tal­ented indi­vid­ual could mas­ter an extra­or­di­nary level of facil­ity with it’s dis­parate bits and pieces. DR’s given tal­ent is writ­ing and draw­ing. And per­haps the most intrigu­ing part was the dis­cov­ery that it can iden­tify it own maker. The text it writes in an arc at the bot­tom of the work below reads “Ecrit par L’Automate de Mail­lardet” or “Writ­ten by the Automa­ton of Maillardet.”

There are videos (1) and (2) on the web­site that show the amaz­ing facil­ity of this cre­ation. In one of the videos the Draughtsman-Writer cre­ates the ren­der­ing of a sail­ing ship below.

Winding Watches

My design for a mul­ti­ple watch winder

Many objects made by human hands through­out his­tory speak to the need to accom­plish some­thing extra­or­di­nary. Often such objects sim­ply arise from a single-minded ded­i­ca­tion and a fair bit of skill. In other instances, such an unusual object could only result from the meet­ing of maker and benefactor.

no 106 Breguet

One intrigu­ing exam­ple of the lat­ter is the Breguet watch no 106 designed for Marie Antoinette. It is a tour-de-force of 18th cen­tury horo­log­i­cal tech­nol­ogy com­mis­sioned in 1783 (with no time frame and an unlim­ited bud­get) as a gift by an anony­mous admirer. It wasn’t com­pleted until 1827 — after Marie had been sent to the guil­lo­tine and Breguet had passed away. I’ll refrain from com­ment­ing on the polit­i­cal, eco­nomic and soci­etal cir­cum­stances sur­round­ing the cre­ation of this watch but its recent his­tory serves as a book­end for a story that’s a sure can­di­date for a com­pelling film plot. The mas­ter thief Na’aman Diller, a per­fect heist, an unsolved case and a one-of-a-kind watch made for a queen.

With its rock crys­tal faces — it was clearly intended to fully dis­play both the effort that went into its mak­ing and the won­der of its 23 “com­pli­ca­tions”. But more ger­mane to this story is the fact that Marie Antoinette was the first cus­tomer for Breguet’s self-winding watch design called the per­pétuelle.

The self-winding mech­a­nism of a mechan­i­cal watch is depen­dent upon the move­ment of the watch wearer to spin an out-of-balance fly­wheel con­fig­ured as a pen­du­lum whose back and forth move­ment is uti­lized to keep the watch wound. This in turn is pred­i­cated upon the owner actu­ally wear­ing the watch …
And, in the case of a watch such the No 106 Breguet, this is vitally impor­tant since the halt­ing of the watch mech­a­nism means not just man­u­ally wind­ing the watch but reset­ting (with­out a key­board) each of its var­i­ous com­pli­ca­tions as well.

So pic­ture your­self a col­lec­tor of con­tem­po­rary and vin­tage mechan­i­cal watches. (Check out the Breguet site for an exam­ple of the cur­rent state of affairs). You own a col­lec­tion of watches — many with mul­ti­ple com­pli­ca­tions and maybe even a few with the leg­endary tour­bil­lon mech­a­nism. To insure they are all ready to wear with­out tedious adjust­ment of the mech­a­nism they must be kept wound. Sure, you could spend your morn­ings going through the col­lec­tion man­u­ally wind­ing each watch in turn (or maybe strap them all to your arms, don a full black cape and go for a nice long stroll.) But as it hap­pens, the eas­i­est way to keep them all tick­ing is to arrange a means of sim­ply rotat­ing them on the mechan­i­cal axis for a given num­ber of turns per day and all is well.

Maybe some­thing like this … Strap the watches onto the rotat­ing and spin­ning arms and set the whole thing in motion.

The com­mon solu­tion is more like this:

Oribita Avanti 12 watch winder

A nice cab­i­net with indi­vid­ual winder mech­a­nisms for each watch. Sim­ple, effi­cient and to-the-point.

But take another look at the Breguet no 106 above. The watch is a minia­ture mechan­i­cal cir­cus act in a glass case. There were much sim­pler watches even in Marie Antoinette’s day (she reput­edly car­ried a sim­ple® Breguet watch to the guil­lo­tine.) Such a watch served the time keep­ing func­tion quite sat­is­fac­to­rily. It’s clear from a review of the cur­rent offer­ings that the typ­i­cal watch winder of the present day is a philosopi­cal sib­ling of the sim­pler Breguet.

So I won­der why such mechan­i­cal poetry as is dis­played in the no 106 might not also find its way into a watch winder. Clearly most per­petuelle own­ers would be inclined to have their watch col­lec­tion han­dled by a winder like the Orbita Avanti. But surely some­one would enjoy hav­ing the watch-tending chore man­aged by a more engag­ing mechan­i­cal con­trivance such as the design that begins this posting.

As it turns out, I was com­mis­sioned to pur­sue this very idea.

Timely motion

winder

Some­times the odd­est things come along.
Fas­ci­na­tion with the dance of elab­o­rate mech­a­nism designed to sub­vert mod­ern tech­nol­ogy inspired this design.
Perched at the edge of the notion “Automa­ton”, this con­trivance, to be made from brass aided by pre­ci­sion stain­less steel bear­ings, will be sus­pended within an elab­o­rate case designed to pre­serve its func­tion and pro­tect its pre­cious cargo. A poetic means to an arcane task.
More than that I can­not say …
