James Goold Cutler received U.S. Patent 284,951 on September 11, 1883 for the mail chute. The first one was installed in 1884 in the Elwood Building in Rochester, New York. Cutler ultimately received thirty patents for variations of his invention.
The first experimental "Cutler mail chute" device was successful at the Elwood Building so later it was installed in two New York City office buildings. Additional ones were then installed in railroad stations and some public buildings as a test. Eventually Cutler Mail Box produced over 1,600 such devices in buildings over the next twenty years. Then the postal service allowed "Cutler mail chutes" to be placed in hotels taller than five storeys. They were also installed in public apartment buildings of more than fifty apartments.
It was announced on Sunday, May 9, 1909, by The New York Times, "Cutler and Other Companies Join in a $2,000,000 Corporation".
It is possible for clogs to form in a mail chute. For two weeks in 1986, more than 40,000 letters accumulated in the mail chute of the McGraw-Hill Building in New York City. In 1999, a spokesperson for the New York district of the Postal Service claimed that the service responded to two or three calls to clear stuck mail chutes every week.
