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.
“This improvement consists principally in the manner in which the reed is fixed in the lathe, within which it has a certain play, which is regulated by springs; and also in the means of forming a connection with, and communicating motion from, the back part of the reed-frame, by the intervention of a strap, lever, and wheels, to the yarn beam. A general idea of the result will be obtained from the concluding part of the specification, which is as follows:
In operating a loom with this improvement attached to it, when the lathe is thrown forward, the reed is pressed against the weft of the cloth, and the lathe proceeds on three-eighths of an inch, more or less. This retarded motion of the reed draws upward the strap and wires attached to them and the lever, so that the catches on the upper end of the lever gain a tooth on the ratchet wheel. means the ratchet wheel, the large, beveled cog wheel, the small beveled cog wheel, the shaft, the endless screw, and the yarn beam, are all caused to move.
The advantages of this improvement, are, that a greater quantity of work can be done with the same labour than without it--that the warp is equably delivered from the yarn beam at all times, without reference to its size--that the weft is equably distributed through the whole length of the warp, and cloth can be woven, close or open, at the option of the manufacturer, and, finally, that the yarn beam will cease to move and deliver the warp, whenever the weft is broken, or out. The weight and thickness of the cloth depend wholly on the stiffness of the springs, or flighters.” I claim as my invention the connection of the reed with the yarn beam, and the communication of motion from the one to the other, which may be done as is above specified.”
