Description: |
Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.
“For improvements in the common Water Pump; John Washington Hillias, Baltimore, Maryland, September 16.
The improvements here patented are intended to prevent the introduction of stones or other hard substances through the spout of the pump, or through the slot in which the handle works; and for a better mode of fastening on the head of the pump than that of nailing.
Sliding pieces are fixed in grooves, and pressed forward by springs, so as to close the slot, or mortise, in which the handle works; and a valve, opening outwards, is applied within the spout, to allow of the exit of water, and prevent the introduction of foreign substances. The head of the pump is to be fixed on by spring catches, and staples. These are the improvements which are claimed.
The heads of pumps are not everywhere fixed by nailing; we have repeatedly seen them fixed by staples, hinges, and locks. We some years since contrived a mode of effecting the principal object above proposed, the preventing the introduction of stones, &c. which we will someday describe.”
