Trippensee tellurion/ planetarium : A collectors guide

     Why do people love tellurions....?   Well for me it's a mechanical sculpture.  Add in a dose of history, and suddenly it's a 100 plus year old  apparatus that still works, and could if desired go right back into a classroom tomorrow.   If an antique globe is holding history, then an antique tellurion is history in motion!    
     When I wrote about planetariums and tellurions back in 2014, it quickly became and still is one of my most viewed posts.  This is telling me that there is a lot of interest in the collector market surrounding them.   It is with this in mind that I write this post as a bit of market analysis, as well as a rough guide for collectors looking to acquire one.
     I keep mentioning Trippensee because they are 90 plus percent what your going to find available in the market place.   That is not to say they were alone, there were earlier devices and some competitors over the years but they dominated.  Hence my concentration.
A pre 1908 Laing/ Trippensee
in exceptional condition
     The oldest Trippensee Planetariums are actually  re-branded Laing devices. They are characterized by string pulley systems and wooden gears. Rare and expensive they are seldom seen and usually need professional attention to be functional, they all sport the same Rand McNally 1891 globe as later models.

      The oldest planetariums of Frank Trippensee's design came in 1908 and they feature the maple construction, brass, and chain drives as is seen in the picture at the top of this page, they were manufactured roughly from 1908-1925. The later maple planetariums of the 1920's had oval name plates with serial numbers stamped on.
   
Planetarium from 1925-1940
 Around 1925 and continuing until 1940 or so Trippensee planetariums were still made of wood, but now the wood was painted black, they also had oval name plates with serial numbers.  The 4th and really final iteration of The Trippensee design is the switch to Bakelite and plastic, gone are the brass, and wood of older designs in favor of newer materials, these designs are technically still made today, they are date stamped under the weighted base.
     So what should a collector consider if they want to add a planetarium to their collection.   I'll be upfront and tell you that I've been researching these devices for quite a while but I've only managed to acquire one example.    With that admission I do think I can offer some advice when it comes to finding, buying, and restoring these devices.

look for no missing parts and
an intact globe
1.  Condition is everything,  it is far more desirable to buy a tellurion in working condition than to buy one in a state of disrepair. The price difference between a tellurion in excellent condition and one in fair condition is dramatic. As much as 50-70% less if missing parts or not working!  Pay special attention to the globe, and the sun.  It is far more desirable to have an intact globe and a brass sun without dents.   That said, these are fairly simple and straightforward, all the works is exposed so troubleshooting is not impossible.  Now, a piece of missing chain....? OK that's a straightforward fix.  However if the tellurion you are considering purchasing is missing parts other than the chain I would stay away, they are just too costly to fix, and finding replacement parts is next to impossible.


2. Age, these things have been made for 120 years,  obviously the newer the tellurion the less expensive it will be to acquire.  Excellent examples from Laing, are most valuable, then very early Trippensee planetariums.  Far less valuable are the Bakelite and plastic models of the 1950's,  even less valuable are the electrified versions of the mid 1960's.  The black painted wooden planetariums certainly command more than the Bakelite ones but always seem to sell at a discount to the maple wood planetariums,  on the order of 20-40% less.

     So lets get down to it, what will it cost to add a nice early Trippensee planetarium to your collection ?  I've been researching these for years and the market is wide ranging for example the high water mark was achieved at Sotheby's NY this past December  They sold a near identical Tellurion to mine for $6800 including buyers premium,  an outlier of a price to be sure.  More down to earth  In 2016 Brunk Auctions of Asheville NC  sold an early Trippensee for $2800.   Also in December in NY  Bonhams  sold an early tellurion for only $685,  it was missing the compass and the name plate on the arm,  this shows how missing parts just destroy the value!  Incidentally I paid $2750 for my example, I think I did OK, I plan on keeping it for a long time.
Mid century tellurion, look for a
complete and functional model

     So I know what your thinking,  I don't need a really early tellurion I'd  be just as happy with a later model.  Well lately those have been landing anywhere from $500- $900 depending on condition.  I can't recommend buying a mid century tellurion unless it's in quite nice shape and completely working.  don't spend money on a project piece at this level.

     Now finding a tellurion for sale takes some time.  I can recommend starting you search with  Murray Hudson antique Maps, Prints, and Globes  He usually has a nice example Trippensee in stock and available for purchase.  Also you can try George Glazer Gallery  He oftentimes will have a nice tellurion in stock for sale as well.  After that they do turn up on eBay from time to time, as well as at large and small auction houses alike.   The difference will be a dealer will stand behind the sale 100%, whereas an auction house is always buyer beware.

Trippensee Planetarium, an in depth look

     Trippensee planetariums are an object that demonstrate cross collectability perfectly.  Globe collectors love them, general scientific instrument collectors love them, and astronomy collectors also covet them. That is not to mention that their mechanics and clockwork like design also appeal on a sculptural/ steam punk level. Because of this,  prices for good examples of these planetariums have seen a steady rise. In fact dare I say they are the strongest segment of the globe/ instrument market.
     I've been in that market for several years trying to obtain a great example.  I've been constantly chasing higher and higher auction prices in pursuit of one, always falling short. Any regular reader of this blog will know that I'm allergic to overpaying.  I'm sure in a rising market this has been my main stumbling block.   Well just a short time ago I was finally able to obtain an example of a Trippensee Planetarium, and dare I say it's quite a nice one,  lets explore.....
Trippensee planetarium c 1908-1920


     I have here a 1st generation Trippensee Planetarium.  This is characterized by the maple wood construction, later examples are made with black painted wood, still later Bakelite and plastic. This one is early. The maple construction dates this Planetarium from 1908-1925.   It's near impossible to pin down the date more specifically because the construction stayed the same for many years. Even the globe was used for many years without geography updates. You see geography was not important on these devices, so why pay the expense of updating the globe.
     So let's examine the fine points of this Planetarium.  This example is all original, no replacement parts, and no restoration.  The small Globe ( by Rand McNally) is the most delicate and therefore usually the first piece to show heavy wear. Here we see that the globe remains bright, legible and near completely intact.
 The next area of concern for these planetariums is the brass sun, they do dent fairly easily, and the brass wears away sometimes. Here again dents have been avoided and the brass finish, though not perfect does retain its luster.   All of the gears are intact with proper chains. The compass built into the arm is of course present and functional.  This example functions smoothly and correctly, in fact my son and I played with it quite extensively and it is a robust mechanism. I see why these have survived in such numbers even 100 years later.
     I would be hard pressed to find a better example.  It was especially important for me to find one with an intact and clean globe.   I did not find this one inclusive of the original wooden crate,  a precious few still boast this. Trippensee Planetariums can be broadly placed into 4 age categories each with its fine points to consider as well as price differences.

     The oldest Trippensee Planetariums are actually just re branded Laing devices. They are characterized by string pulley systems and wooden gears. Rare and expensive they are seldom seen and usually need professional attention to be functional, they all sport the same Rand McNally globe as  these later models.  The oldest planetariums of Frank Trippensee's design came in 1908 and they feature the maple construction, brass, and chain drives as is seen in the picture at the top of this page, they were manufactured roughly from 1908-1925. The later maple planetariums of the 1920's had oval name plates with serial numbers stamped on.
     Around 1925 and continuing until 1940 or so Trippensee planetariums were still made of wood, but now the wood was painted black, they also had oval name plates with serial numbers.   I have been trying to purchase one of these for a while and I decided some time ago that when I did purchase one of these devices I wanted it to be one of the earlier versions.  Nothing against the Bakelite and plastic planetariums of the 1950's these older examples just appeal to me more. I'm clearly a sucker for the brass, wood , and paper combination.  it just screams I'm old I'm from a different time, and I love that.
2 versions of the same 3 inch globe
     A while back I wrote a blog post titled, " sometimes it's OK to overpay"  well this in my mind is one of those times.   Every year that clicks by these devices become harder and harder to find.  It was with this in mind that i decided the time to move was now.   Also when you love something it's OK to pay up to obtain such a thing.
     I wouldn't be a globe blogger if I didn't take time to explain more about the globe used on these planetariums.  It is a copyright 1891 Rand McNally 3 inch orb.  Rand McNally produced this globe as the smallest in their line and fastened it to a multitude of different bases.  It's no surprise then when Laing/ Trippensee needed a small globe for their tellurion they went to Rand McNally.  This globe with it's 1891 geography was used into the 1930's on these tellurions, earning a far longer life than would have otherwise been warranted. To the right is a picture of my Rand McNally 3 inch next to the tellurion globe. Both cartouches are in the shape of a shield, one reads Rand McNally, the other Trippensee, but they are otherwise identical.
     in closing while researching I stumbled onto something intriguing, a patent from Frank Trippensee dated 1909 for a different model tellurion.  An expanded device that added a second horizontal arm and then attached a Mars globe at it's end.  You can read the complete patent documents here: Trippensee mystery planitarium   I can't find any record of this device actually being manufactured ..............what might have been........
Trippensee patent  for expanded Mars tellurion, 1909

***** Update!!    In certain areas of collecting there are levels of completeness, for example in book collecting having the dust jacket of a book that was originally issued with one is much better than not having it.  Well with completeness in mind  I started searching for the original manual that would have accompanied this device.   Now over the years so many of these planetariums got separated from the original instruction manual. Remembering that these were used as instructional aids in schools.  The original manual is a rare sighting, now they do pop up from time to time.   As luck would have it I stumbled into a copy using a search technique that I've used in the past.  Once in a while you can score a great find looking on eBay for misspellings and  mis-categorized listings. That was the case here a slight misspelling and a not ideal category choice let this handbook slip through the cracks so to speak!
Trippensee instruction guide
note the date stamp, bottom
of title page
     This instruction manual was copyrighted in 1908 by Howard Hovey, it was included with each planetarium sold and was unchanged until the early 1940's when the device changed to Bakelite and plastic construction.  Interesting to note, on the title page inside the cover the Trippensee company dated the manual and I believe it was changed each year this date looks to be separately stamped in so if you have the original manual with your planetarium then looking at this title page should give you the exact year of manufacture.  
Profusely illustrated,
but a very dry read.
      Now having an original booklet really elevates this item because the vast majority of these planetariums do not have the book available.   This is true of vintage globes in general each of them originally came with a handbook, Joslin, and Andrews produced hard cover books, most manufactures produced soft cover booklets . Certainly having the original handbook just adds to the total package. In the case of the Trippensee tellurion it adds guidance as to how to actually use the thing intelligently, a wonderful find.

Just a quick update

     Well i've been absent from the blog for a couple of months.   However that is about to change, look for some interesting new posts just around the corner.   Buying has been sporadic as of late but research is ongoing.  Remember collecting is 10% buying and 90% learning ( perhaps I'm too generous on the buy side)
     Coming up I'm going to review some very interesting auction results, as well as I'm going to share a very special addition to my collection.     Until then  happy hunting.......
