I deal in, buy and sell antique & collectible Office, Scientific, and Technology related antiques that date from near the turn of the 20th century or earlier.  This includes office related tools such as early patented antique pencil sharpeners, antique typewriters,calculators and many early electrical devices   We also deal in such things as vintage slide rules, early punch style check protectors, antique fans and other early office related collectibles. 

When I first started looking for technological and office antiques some 30 years ago many were considered to be just heavy weights.  They would be found hidden in the corner of antique mall booths or under the table at antique shows.  Jokes abounded about anchors, ropes, dumpsters and such.

Those days are over and the word has spread.  Thing is, today everyone wants to sell their 1940's - 1960's era obsolete office stuff for big bucks because of the stories they have heard, or TV shows they have seen.  They just know that their "old" and "antique" 1950's  typewriter or adding machine is valuable.  Age, rarity, or condition are hardly considered.  While that logic might hold true for first generation computers and electronic calculators, for the most part office equipment from the 20's through the 60's is not in demand, desirable or worth much at all.

The bad news  is that the anchor analogies, along with the rope and heavy weight jokes still pertain to many of these later pieces.  The 1930's or later used typewriters or electric calculators, that have been sitting in the garage or in storage the last 40 years, time has not yet come.  The market may change over time for this later, readily available, and more common stuff, but I will not be around to see it, and you probably will not be either.

On the other hand, the supply of good early (pre 1900) scientific related antiques, that was once available and reasonably priced, has now for all intent and purposes disappeared from the scene and the supply has about dried up. It is that era stuff that I am looking for today, and can help you sell. 

If you have a single antique or an entire collection of office and technology related antiques for sale that you think we may be interested in, please contact us at LCM@patented-antiques.com and we will get back to you ASAP.  Thanks!!

Antique Typewriters

Typewriters are a another popular collectible in the Office Antique category, and again the more interesting and earlier models are becoming ever more difficult to find. To see a small sample of machines I have previously sold in the past and to get an idea of the types I am looking for please look at our Past Sales Archive at our sister site www.AntiqBuyer.com. . 

Now is the time to buy antique typewriters as their perceived values have done much the same as the NASDAQ in the recent past, with wild swings up and deep declines down after a few hungry, and money is no object, style buyers entered the market and were filled up. But as with the stock market I think we have seen the bottom, and when the business collectors of antique office memorabilia get their priorities and portfolios back on track, this sort of antique office collectible is again going to sell at a whole new level of price, to a whole new crop of interested buyers and the cycle will begin again. 

All the different styles and examples are a great example of a technology that went through some wild changes and stages of development to the keyboards hooked to a computer we have today.  Personally I can not imagine using a typewriter and not having spell check.

Patented & Mechanical
Antique Pencil Sharpeners & Check Protectors

*** Click Heading to see Items ***

Antique mechanical Pencil Sharpeners or pointers that I am interested in and buy and  sell saw their heyday of innovative design and production during the period from about 1870 to 1910 or a bit later.  There are a myriad of patented designs and variations on designs available and they can make for an interesting and challenging category to collect.  Their availability has ebbed and flowed with the the internet and so has their popularity. Our current inventory has been pretty much depleted, but we are still buying more unusual and interesting examples.  There are many many different versions available and you can see a pretty good selection of what I have sold in the past by visiting this pencil sharpener sales archive page at our sister website  In general we are seeking to buy any of those seen on the preceding page, but are even more interested in odd-ball mechanical and patented ones that are not shown.

Early Electric Appliances
Fans / Motors & Steam Engines

Antique electric fans offer a glimpse into the quality and pride that went into the manufacture of products in this country during an earlier period in America's history. I still use a an early GE Pancake fan and a Westinghouse "Tank" fan, as well as an early electric Emerson fan around the house.  The way they work and look is a tribute to an earlier time.  A sense of pride was built into American made products and these 75-100 year old fans are a great example of the way things use to be.  It is no wonder these early testaments to quality and design stir collecting interest, or that they elicit positive comments from all who see them. Their operation and their their look have an air of quality about them not seen in today's products.

Early fans came in all sizes and shapes. Some examples of ones I have sold in recent years can be found on this fan sales archive page at our sister website.   In addition to electrically powered AC, DC, or battery powered fans, there are hot air fans, water powered and and more..  I deal in and sell all of these early versions of vintage fans.

Most small or toy vintage electric motors resemble early larger antique steam and electric motors from the same time period or era and are open framed and or bi-polar in design.  Many of the electric motors that came with erector sets or with toy steam engines like Weeden and Bing are similar looking but there are earlier and more elaborate models that were used as demonstrators in classes or labs as well.  Others were sold in Novelty catalogs as working motors for small jobs.   In addition to electric motors there are also hot air models known as "flame lickers", and the steam driven motors / generators meant to be set up with boilers by such makers as Bing, Jensen, Plank and others.  

Names like Edison, Westinghouse, Tesla and a few others come to mind when  considering the introduction of electrical technology into our society.  These inventors and others were the driving force that led America into a new age of power and their early efforts and designs are both important and an interesting facet of our history and a reminder of what it used to be like.
