Monkey jockeys race greyhounds

In the early 1930s, a new feature was introduced at some greyhound races: monkey jockeys. Apparently the crowds loved the idea. The problem was, the monkeys had trouble staying on the backs of the greyhounds. Animal trainer Rennie Renfro came up with a solution — a special harness that would tie the monkey onto the back of the dog. Renfro patented his invention in 1933.

It probably made him some money, because I can find descriptions of races with monkey jockeys for decades afterwards.

Airplane Hat

Created by Gilbert Myers of Boise, Idaho. He was evidently worried that someone might steal his idea because, in 1929, he patented it. From the patent:




The picture below shows the airplane hat being worn. (The accompanying article identified it as Myers's hat).

These other photos, of actress Alice White, I'm not so sure about. It looks a lot like his hat. If it isn't, someone ignored his patent.

Advertising Chairs

Back in 2018, Paul posted about an "advertising chair" patented in 1910. As a person rocked in it, advertisements scrolled in the armrests.

Patent No. 958,793 (1910)

I recently discovered that this invention wasn't a one-off. In the early twentieth century, inventors were actively competing to perfect advertising chairs and inflict them on the public. I was able to find four other advertising chair patents (and there's probably even more than this). To my untrained eye, they all look very similar, but evidently they were different enough to each get their own patent.

Patent No. 934,856 (1909)

Patent No. 993,397 (1911)

Patent No. 1,094,154 (1914)

Patent No. 1,441,911 (1923)

A newspaper search brought up an 1895 article that described advertising chairs as the "latest in advertising." It also explained that the concept was to put these chairs in various places where there were captive audiences, such as "hotel lobbies, public libraries, depots and in fact in all places where tired humanity is used to taking a quiet little rest during the day."

Minneapolis Star Tribune (Dec 8, 1895)

But although entrepreneurs may have been keen to build advertising chairs, the public was evidently far less enthusiastic about them. An editorial in the Kansas City Journal (reprinted in Printer's Ink magazine - Jan 2, 1901) described an advertising chair as "comfortable enough physically, but mentally it is a torture... Just who invented the advertising chair is not known. He has no reason to be proud."



There must have been a number of these advertising chairs in existence, but I'm unable to find any surviving examples of them. Searching eBay, for instance, only pulls up chairs with advertisements printed on them.

Shoe Gongs

Anthony Faranda of Yonkers, NY worried that children didn't like wearing rubber-soled shoes because they made no noise when walking on a pavement. So, he invented a shoe gong. Or, as he called it, a "footwear actuated noise maker." He patented it in 1957.

It was a disc and clapper that could be worn over shoes. He explained: "The arrangement is such that upon normal walking steps or running strides the clapper is activated to make noise and thereby promote the interest of children in wearing shoes with soles that do not make an audible sound in engaging firm or rigid surfaces."

Maybe kids would have liked these, but not, I imagine, their parents.

He assigned the patent to the NY advertising agency McCann-Erickson. It's unclear what plans they might have had for these things.

Throwing Animals for Taking Death Leaps

Circus proprietor Edward Wulff patented a curious device in 1904. It was an apparatus that catapulted animals upwards. It had the rather alarming title, "Throwing Animals For Taking Death Leaps" (Patent No. 774,017). Wulff claimed it could throw "horses, elephants, monkeys, &c.." The patent illustration shows a horse, so these were evidently the primary animal being thrown.



The device was relatively straight-forward. The animals were placed in a harness that held them on top of a spring-powered platform. The release of the springs then flung the animals upwards. Wulff emphasized that his apparatus was designed, via the harness, to place the projecting force on the full body of the animal, rather than just their legs. He seemed to feel that this was a safer, more humane method of throwing animals.

Wulff explained that this device was designed to be used as part of a circus stunt known as "a death leap or so-called 'salto-mortale.'" But he didn't offer any further explanation about the nature of the stunt or how far the animals were flung. And I couldn't locate any descriptions of this stunt in other sources. All the references to a 'death leap' stunt that I came across involved human trapeze artists, not animals. So I was about to conclude that the stunt would have to remain a mystery until I got the idea to check if Wulff had filed the patent in any other countries. Sure enough, there was a British version of the patent, and while its text was almost identical, it had a different title that explained the nature of the stunt:


So Wullf's apparatus was evidently designed to somersault animals. Not simply to catapult them upwards. This made me recall something I posted here on WU back in 2012. It was a brief item that appeared on the front page of the Washington Post's 'Miscellany Section' on April 21, 1907, titled 'Horse Can Turn Somersaults.' At the time, this random reference to a somersaulting horse totally baffled me. I even suspected it was a hoax. But now it makes sense. It must have been a circus stunt. Perhaps it even made use of Wulff's invention. I can't find any evidence that Wulff's circus was in Boston in April 1907, but it was in New York in December of that year.



Wulff, it turns out, was the author of another odd patent, granted to him in 1887. The patent was titled, "Means and apparatus for propelling and guiding balloons." He intended to use birds such as "eagles, vultures, condors, &c" to guide balloons. The birds would be attached to the balloon by a harness, and an aeronaut would then force them to fly in the desired direction, thereby propelling the balloon.



This patent has received quite a bit of attention, because there's a lot of interest in the history of early attempts at flying machines. Knowing that Wulff was a circus proprietor, I wonder if he intended his eagle-guided balloon to be used as part of a circus act, rather than as a practical flying machine.

Suntan Suzy Doll

Suntan Suzy was a doll that would develop a tan if you put her in the sunlight. Back in the shade, her tan would fade. She came on the market in 1962, but lasted only one season. As far as I can tell, she was the only doll that has ever had the ability to tan.

Arizona Republic - Nov 23, 1962

The chemistry responsible for producing the tanning effect is described in Patent No. 2,921,407 (Jan 19, 1960) – “Simulating Sunburning Toy Dolls and Figurines”:


It seems like an interesting gimmick for a doll. Curious it never caught on.

Shave-O-Mat

Harry Thalheim believed that “a need has existed for a long time for a shaving emporium where people may shave cheaply and rapidly at all hours of the day and night.” So, in 1964 he patented the Shave-O-Mat (US Patent No. 3,120,886). It was a coin-operated shave-yourself establishment, open 24 hours a day.

Did this address some kind of market need in the 1960s? Were there men who, in the middle of the night, really wanted to shave but couldn’t?

I'm guessing not, because, as far as I can tell, Thalheim's Shave-O-Mat never opened.

The Beautiful Beauty Mask

Patented in 1954 by Ann S.V. Mann of Petersburg, Virginia.

It functioned like any other beauty mask. Its primary difference, claimed Mann, was that her mask had the outer appearance of a "strikingly beautiful woman":


Due to the uncanny valley effect, she may actually have ended up creating something that looked more grotesque than a regular mask.

Cow burgers and hot dogs

In 1950, Rodney Graves of Arizona patented cow-shaped burger patties. However, he missed an opportunity by not also patenting a cow-shaped bun.



Edward Kiwala of Chicago didn't make a similar mistake when, in 1969, he patented a dog-shaped hot dog (or, at least, a hot dog with four legs like a dog). He also patented the accompanying bun.
