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 a Percussion Lock, and Vent for Cannon; Lieut. William H. Bell, Fortress Monroe, Virginia, October 1.
We are not aware of what constitutes the peculiarities in this lock, when compared with others which have been used for the firing of ordnance; as, excepting in the mere arrangement of the parts, we do not think that it is new. The vent is countersunk to receive the primers, upon which the hammer is to strike. The hammer face is of steek and made to fit into the countersink. The hammer handle projects back and is supported upon a joint attached to the breech. plate. The tail of the hammer is held down by a catch, and, when this is released, a spring, attached to the cascabel by means of screws, forces it down.
The vent is not placed on the top, in the usual manner, but is removed towards one side, so that the sight is not obstructed.
As all the parts are described, without particularizing those which the present patentee has invented, the whole patent may be en
dangered by this neglect. Thus the countersinking of the vent, to receive the primer, stands as conspicuously as any other part of the arrangement. Is this new?”
