On October 6, 1831, E. N. Sherr received U.S. Patent No. X6788 on a Guitar:

Sherr’s guitar was really big. However, it was far from the largest guitar. According to the Guiness Book of World Records, the largest playable acoustic guitar is one measuring 16.75 m (59 ft 11 in) long, 7.57 m (24 ft 10 in) wide and 2.67 m (8 ft 9 in) deep (the box of the guitar can easily accomodate 20 people). It was built by Realizarevents, of Porto, Portugal, and weighs four tons (8,818 lb). It took 50 people more than 10 months to complete.

According to that same source, the world’s largest electric guitar is petite by comparison, measuring a measly 13.29 m (43 ft 7.5 in) tall, 5.01 m. (16 ft 5.5 in) wide and weighing 907 kg (2,000 lb). It is modelled on a 1967 Gibson Flying V and built to a scale of 1:12 by students from Conroe Independent School District Academy of Science and Technology, Conroe, Texas, USA at a cost of US$3,000. |Construction began in October 1999, and it was played on June 6, 2000.

On October 3, 1967, U.S. Patent No. D208849 issued to James D. Smth and Rober C. Flint on a Sign:

The sign in question was the Flint’s Hamburger sign, a hamburger chain with multiple locations in Ohio, and at least one North Carolina location, although none of the locations have survived..

The sign was topped with a neon-lot Roto-sphere, an icon of the 1960’s, although it was not part of the design as it is shown in dashed lines. Only about 200 Roto-spheres were made, and unlike FIlnt’s, at least a few survive:

On October 2, 1979, Richard E, Meyer and Pierre Dinand received U.S. Patent Nos. D283035 and D283036 each on a Combined Bottle and Cap:

These were assigned to Jovan, and those of us who were around in the late ’70’s and early ’80’s will remember these interfitting Jovan cologne bottles:

the line was discontinued, and today matching sets are considered rare vintage collector’s items.

On September 30, 1958, U.S. Patent No. D183613 issued to Kenneth E. Joy, on an inflatable building:

He improved the design and received a second patent (U.S. Patent No. D187690) less than two years later:

From the late 1950’s to the late 1970’s, the world of Architecture was fascinated by the idea of inflatable buildings, for radomes to protect radar installations, pool enclosures, lunar habitats, green houses, and as Mr. Joy was proposing, exhibition halls.

Today’s patents of the day are a glimpse back into 1942, less than a year after the bombing of Pearl Harbor and the U.S. entry into World War II:

Metals, badges, and even playing cards are just a few of the patent that issued this day reflecting on what was everyone’s mind in 1942.

On September 27, 1966, U.S. Patent No. D205876 issued to James S. Merritt, on a Frozen Confection:

The patent, which was assigned to the James S. Merritt Company of Kansas City, covered the popular BOMB POP. The BOMB POP name was registered December 12, 1972 (Reg. No. 948643).

Merrit eventually registered the configuration of the BOMB POP with the red, white, and blue coloring as a trademark in 1976 (Reg. No. 1039931), and the configuration irrespective of the coloring in 1979 (Reg. No. 1127938).

On September 26, 1967, U.S. Patent Nos. D208754 and D208755 issued to John O. Hruby each on a Water Fountain:

What is unique about these patents is that they are directed to the flowing water, and not any permanent physical structure. Unfortunately for Mr. Hruby, he had to go to the CCPA get his patents. See, Application of John O. Hruby, Jr, 373 F.2d 997 (C.C.P.A. 1967).

On September 22, 1959, U.S. Patent No. D186,162 issued to Borje Sjoman on a Motor Vehicle:
