MACHINE FOR COMBING WOOL, &c. SPECIFICATION forming part of Letters Patent No. 271325, dated January 30, 1883. Application filed March 10, 1882. (No model.) To all whom it may concern: Be it known that I, CHARLEs FLETCHER, partsto cause is itgreater to work than effectively is necessary at these for harderthe ef. ofIsland, the city have of Providence,invented a innew the and State useful of Rhode Im fective operation of the more elastic parts of 55 provement in Machines for Combing Wool, &c., the apron; and as any practicable joint formed of which the following is a specification. by the uniting of the ends of such apron is My invention relates to that class of ma necessarily much harder and less elastic than clines, known as “ combing,” “carding,” and the other parts, it is obvious that my seamless “drawing' machines, for preparing the sliver apron requires less tension to cause it to work 65 of wool fiber. In such machines front and back effectively and evenly in drawing the fiber in draft-rolls have heretofore been used in a well all its parts than a jointed apron, and this en known manner, and an apron bas been used ables the entire machine to be operated witly with and passing between the front draft-rolls less power and wear of parts. in a well-known manner, to aid in the drawing Having thus described the principle upon 65 process, such apron having been constructed which my invention operates, I will now pro with a seam or joining across it where the ceed to describe its construction as used upon ends were brought together. a wool-combing machine.
