. tively, of the borough of Brooklyincounty of the machine.
Kings, State of New York, borough of Manhattan, county of, New York, State of New York, and borough of Brooklyn, county of Kings, and State of New York, have jointly invented certain new and useful Improvements in Adjustable Automatic Knitting Machines, of whichthe following is a speci- .ficatioii.
This invention relates to improvements in adjustable automatic knitting machines.
The object of the invention is the production of means to produce knitted material of predetermined lengths. Its second object is the production of a knitted material with stitches of various designs and combinations and colors. The third object of the invention is the production of means whereby the various adjustments thereof can be easily controlled by the operator. illie fourth object of the invention is the production of a knitting machine whereby the speed of operation is greatly increased. A fifth object of theinvention is the production of means whereby the yarns that go to .make up the finished product can be changed automatically during the knitting operation to give certain colors.
A sixth object of the invention is to automatically change the style of stitches in the product produced during the operation of A seventh object of the in: veiition is the production of a knitting machine in which the usual cam chains are not required.
