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. Only the patent drawing is available. This patent is in the database for reference only.
“For an improvement in the Brick Pressing Machine; John Woodson, Rockbridge county, Virginia, September 10.
An upright iron rod is fixed so as to slide up and down in front of a strong vertical post; on the bottom of this rod, is the platen, or follower, which is brought down on the mould containing the brick. The force is applied by hand to a progressive lever, and the brick is to be thrown out of the mould, by means of a weighted lever, which is made to act under the brick, when the lever of the press is raised. The claim is the combination of the different parts, the plication of the lever power, and the increasing power of the lever.
We do not perceive much of novelty in the arrangement, nor do we believe that any one can sustain a claim to the increasing power of the lever, when the operation of the progressive lever is so well known, and so frequently employed.”
Journal of the Franklin Institute Vol. 9, Dec. 1829 pg. 401
