In 1927, the Canadian patent office granted an unusual patent (CA 259317) to George L. Kavanagh. It was unusual because, while most patents describe some new type of gadget or gizmo, Kavanagh's invention simply consisted of a method of using a carrot.
The problem Kavanagh had set out to solve was that of constipation in the elderly. The way he saw it, our rectums tend to grow more inelastic and shrunken as we age, and this leads to constipation. The solution, he concluded, was "gently dilating the anus and rectum until the organs are restored to their youthful size."
But what could be used as a dilator? Preferably something inexpensive and readily obtainable. That made him think of carrots.
A summary from his patent:
An added benefit of carrots, he noted, was that they come in a variety of different sizes. This would allow one to start with small carrots and work up to larger ones "until the desired result is obtained."
Unfortunately, Kavanagh submitted no drawings with his patent. But I did find a chart that provides a size comparison of different types of carrots, which could be potentially useful for anyone who wants to try out Kavanagh's method at home on an elderly relative.
The British patent office granted William Redgrave two patents. The first (No. 2888 - 1853) was for a "safety travelling cap". The second (No. 762 - 1859) was for a "pillow travelling cap". However, the two patents seem to describe the same invention. They just emphasize different uses for it.
Redgrave's patented cap consisted of three air-tight, circular tubes that would wrap around a wearer's head. His idea was that this would provide a measure of safety for travelers, because if the traveler fell the inflated tubes would cushion his head:
Thus, should a person wearing it be violently thrown against the sides of a railway carriage or in contact with a person on the opposite seat to him, or be thrown from a carriage, chaise, or any other conveyance, his head is perfectly secure from injury.
The cap could also serve as a pillow (thus, the second patent):
A person wearing the cap can repose with the greatest comfort in any position, quite as well as if he had a pillow placed beneath his head, and is werewithal as light as any ordinary cap; it is excellently adapted for travellers to and residents in hot climates, forasmuch as they can throw themselves on the deck of a vessel or anywhere else, and enjoy a most comfortable repose.
Finally, Redgrave noted that the cap was "an excellent invention for lunatics." Presumably because lunatics might fall over a lot. Or hit their head against a wall.
Unfortunately Redgrave provided no drawings of his safety cap.
In 1920, Richard Jefferies was granted a patent for "a simple and practical device which will eliminate the habit of breathing through the mouth and at the same time will assist in harmonizing the facial features of the wearer, by more evenly balancing the muscles of expression."
His invention consisted of a piece of adhesive-backed silk placed over the mouth.
I was vaguely aware that mouth breathing is considered a bad habit, but I wasn't aware that "mouth taping" continues to be a common remedy for it.
For instance, one can buy SomniFix Sleep Strips, which look like they're a slightly updated version of Jefferies' invention.
This invention relates to a casket, and more particularly to a casket having support means therein for supporting the body against shifting longitudinally of the casket.
In the past, caskets and vaults have been buried in a substantially horizontal position. Burial space, especially in urban areas, is becoming more scarce. A solution to such a problem may be found in burying caskets in a substantially vertical position. With such burial techniques, the amount of space required for each burial is substantially reduced.
While previously known caskets could be buried vertically, rather than horizontally, it should be realized that their use might be found distasteful by those who have been close to the party to be buried. An objection to the use of prior caskets may be found in the fact that in prior caskets generally there is nothing to support the body against shifting toward the foot end of the casket when buried in an upright position. Thus, if a conventional casket is tipped upright the body would slump to the foot end of the casket.
Henry Perky invented shredded wheat. His son, Scott, was also an inventor, though not as famous. He invented and patented a bi-directional, symmetrical font which could be read from left-to-right or right-to-left.
Perky's idea was that this would allow one to read a line of text from left to right, and then read the next line right to left, without having to move the eye back to the beginning of the line. This, he claimed, would reduce "brain fag":
The invention consists in certain means of printing alternate lines, whereby the reading can be done from left to right and from right to left in a continuous manner, and the skipping from the end of one line to the opposite end of the next is avoided.
It is hardly necessary to allude to the strain upon the eyes and brain, which results from much reading. To students, researchers and others whose lives are cast among books, any device which promises to facilitate reading in such wise as to lessen fatigue of the optical tract, and consequent headache and brain fag, will appear of unusual importance.
The Gnathograph, or 'dental articulator', was the invention of Los Angeles dental surgeon Beverly McCollum. He was also the founder, in 1926, of the Gnathologic Society.
The name 'Gnathograph' derived from 'gnathology,' this being the study of the jaw and masticatory system, from the greek word 'gnathos' meaning 'jaw'.
"The formidable contraption shown in the mouth of Miss Pearl Nord is a gnathograph, invented by Dr. Beverly B. McCollum of Los Angeles and demonstrated before the chicago Dental Society. It records direction of bite and fit of teeth and accurately guides a dentist in straightening crooked teeth or fitting inlays, crowns, bridges and plates." image source: Agi Haines
The Pitcairn PCA-2 autogyro was developed in 1931 and proved to be a reliable, unique aircraft. The rotor at its top was unpowered and it flew more like a fixed wing aircraft than a helicopter, based on the power from its radial engine on the nose. Once at speed, the rotor spun based on aerodynamic forces alone thus generating lift. It was an amazing sight and attracted crowds wherever it flew. By April of 1931, the autogyro had flown across the United States at the hands of John M. Miller, had landed on the White House lawn (by test pilot Jim Ray), and had soared to a new altitude record of 18,415 feet (this being Amelia Earhart’s record).
Seizing upon the press interest in the design, the Champion Spark Plug company purchased one and painted the sides with their logo and named it “Miss Champion”. It was the perfect flying billboard. After hiring Captain Lewis “Lew” Yancey, a former Naval Lieutenant and USCG officer who was a maritime captain, they directed that he fly the nation on an advertising tour. By the end of 1931, Captain Yancey had flown the autogyro 6,500 miles, transiting 21 states and touching down in 38 cities around the nation. Yet the Champion Spark Plugs company still wanted more attention — and thus they asked him to beat Amelia Earhart’s altitude record as well.
