About the Inventor
Our most likely census matches suggest Helen Caitlin Traphagen was born in New York around 1830. She was well known in the city as a seller of opera wear, providing customers with the latest designs from a store called Pantechnicon of Fashions on Broadway. Her younger sister seems to have been her dressmaking and retail business partner. They also ran a fashionable boarding house together.
In addition to the USA-filed patent for the inflatable hoop skirt, we also found an incomplete patent application for what would appear to be the same invention, filed in the UK in 1858. (Intriguingly, there are further USA and Canadian patents issued in 1876 to a Helen Caitlin Traphagen, gentlewoman, for a design of window scaffold.) Traphagen gained significant media coverage as a result of her patented skirt apparently gaining favour with Queen Victoria and it was advertised in 1857 as “The Victoria Inflated Skirt”.
About the Invention
PROBLEM
Hoop skirts were petticoats with concentric circles or hoops that supported the familiar dome-like shape of European-style skirts. At the time of Traphagen’s patent, the boning of hoop skirts was usually constructed from canes, baleen, steel springs or other contrivances. Not only were the skirts uncomfortably heavy as a result, but they were also often difficult to store, adjust and manage – particularly while trying sit down or pass through doorways.
SOLUTION
Traphagen’s innovative design used inflated tubes to hold the desired shape of the attached skirt or petticoat. This approach was lightweight and compressible, allowing the wearer to easily gather up their skirts to avoid dragging them through mud, or to sit down without their clothes becoming disarrayed – avoiding what was regarded as a “loss of their dignity”. When not in use, the air could be released from the tubes, enabling the garment to be folded and packed down into a small volume.

“The nature of my invention consists in attaching to the body of a skirt or petticoat a series of air-tight tubes to be inflated with air for the purpose of expanding the surface of the skirt to give a ‘set’ to the dress.”

Hoop skirts are often seen by contemporary viewers as awkward, inhibiting and limiting garments. There is no doubt they were problematic in many ways. Despite this they offered ways for women to claim power at a time when they were otherwise lacking socio-political rights. We are interested in exploring their affordances for adaptability and flexibility and above all, for wearers to make, claim and take space in different contexts. Many have written about hoops as being unexpected tools of identity and power.
“The origins, innovations, fluctuations, and failings demonstrate the tenacity of eighteenth-century Englishwomen in their autonomy. Although it is tempting to condemn the hoop as yet another example of female subjugation through dress, such as the medieval chastity or the crippling corsets of the nineteenth century, the hoop actually had quite the opposite function. In the face of widespread and violent protest from men, women willingly hoop as a means of protecting, controlling, and, ultimately, liberating female sexuality” (Chrisman 1996, 7).
Traphagen’s inflatable hoop skirt was fascinating to us as it is one of the early air-filled inventions that offered flexibility, adaptability and control. It could be expanded and reduced in size by the wearer as needed. It was also lighter and could be stored and carried more easily than steel, baleen and cane versions. This was achieved by using a brand new technology – rubber tubing – which would go on to revolutionise cycling towards the end of the century via the introduction of pneumatic tyres.
We reconstructed Traphagen’s inflatable hoop skirt using a calico petticoat with three concentric circles of rubber tubing. The inventor suggests they do not have to all join as is shown in the patent drawing. Instead, “[E]ach of the horizontal tubes”, she explains, can be “supplied with stop-cocks, so as to adjust the circumference of the skirt to the required dimensions”. A “stop-cock” is a valve for regulating or stopping the flow of water or gas. Using three separate tubes, each with their own “stop cocks” or valves, meant the wearer could avoid the risk and embarrassment of total deflation (which was a very real concern of the time).
We used contemporary bicycle inner tubes, cut and glued together, to make the larger circular hoops. Each was secured inside the petticoat via calico sleeves. We used a bicycle track pump to inflate the tubes, but wearers at the time of the patent could have “raised the wind” using a pair of bellows or by mouth..
We were delighted by the expansive potential of inflatable tubes: the skirt more than doubled in volume! We were also impressed by the parallel tube design which meant that even if one tube failed to stay inflated, the other two maintained the skirt’s shape. This happened to us during testing, and the skirt still kept its intended shape. Another aspect we noted relates to the ease of storage. When not in use, and in its deflated state, Traphagen’s invention hangs neatly on the railings with the other POP toiles, which was greatly appreciated in a small, yet very full, studio office.
