MailboxIn 1858, the first U.S. patent for a street mailbox was patented by Albert Potts of Philadelphia (No.19,578). It comprised a simple metal box designed to attach to a lamppost. By August, these boxes were found along the streets of Boston, Mass., and New York City, N.Y. His patent described the "object of this improvement is to afford greater facilities to the inhabitants of large cities for the depositing of letters, and to enable the carriers to collect, or the citizens to deposit therein, at any period of time." The boxes had a central hole for the shaft of a lamp post, lids covering the drop hole to exclude weather, a sight hole so a carrier could see if any letters had been deposited, and a small door secured with a lock for the carrier to empty the box. |
