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.
"The temples originally patented, consisted of wheels with oblique teeth, which were screwed firmly upon the breast beam. When the beater struck the filling, there being no elasticity in the temples, they were rapidly worn, and their points made holes in the edges of the cloth. In the improved mode, a wooden spring fastened by its centre to the breast beam, extends across the loom, to each edge of the cloth, and upon this the temples are fixed: there are some other improvements in the mode of adjusting them, and causing the points to leave the cloth readily; but to explain these would require the drawings."
