Carpet power-loomIn 1869, William and John W. Murkland were issued a patent for their invention of a carpet power-loom (No. 97,106) as "an improvement in power-loom for weaving in-grain carpet" or other figured fabrics. By making several simplifications to reduce complexity of the machinery, their design reduced the number of cams and levers involved in operating the loom. As a result, less power was required to maintain the motion of the machine. Having fewer parts also reduced maintenance and repair costs.
