Description: |
| Abstract:
We have made certain Improvements in the Machine for Weighing Heavy Bodies in addition to those formerly made by us, and for which we obtained Letters Patent bearing date the 13th day of June, 1831 (Patent #6573X); and we do hereby declare that the following is a full and exact description of our said improvement, reference being had to the drawings which accompany this specification and make part of the same; and we do further declare that in these drawings and this description we have represented and described many parts which are common to other machines for the same purpose and are found in that patented by us as aforesaid, which we have done for the purpose of more clearly explaining those parts which we believe to be new and of our own invention, and which are distinctly set forth in the claim hereunto appended.
Claim:
The variation in the manner of connecting the two levers in the center, (whether they be composed of one or more parts each,) to wit: by means of knife-edges resting in pendulous rings or circles, as shown in drawing No. 1, letter K, and drawing No. 2, Fig. 6, and Figs. 3 and 4. |
