JAMES A. COOPER, OF WHITINSVILLE, MASSACHUSETTS, ASSIGNOR TO THE WHITIN MACHINE WORKS, OF WHITINSVIL LE, MASSACHUSETTS, A CORPORATION OF MAS- SACHUSETTS.
OLEAEER-COVER.
Specification of Letters Patent.
Patented June 1, 1915.
To all whom it may concern Be it known that I, JAMES A. CooPER, a citizen of the United States, residing at WVhitinsville, in the county of Worcester and State of Massachusetts, have invented the followingdescribed Improvements in Clearer-Covers.
This improvement is the result of a long study of the action of the clearers in cottonspinning machines, wherein it has been determined that the soft, fuzzy or spongy fabrics heretofore and generally used as the clearing agent retain as waste a considerable portion of good fiber that might otherwise pass into the yarn, to its improvement, and that as a consequence the collection of waste on such clearers accumulates somewhat faster than would bethe case if only actual dirt and grit were retained, and such waste has thus to be more frequently removed in order to keep it from passing into the yarn in bunches or clots.
The object of my invention has been not only to reduce the amount of fiber accumulating on the clearer, but more especially to reduce the necessity for such frequent attention on the part of the operative and,
of course, without allowing the rolls to become dirty. The number "of frames that can be attended to by a single operator is thereby increased and the yarn is delivered cleaner and with less bunches in it, while more of the good stock goes into the yarn than formerly. I have succeeded in this purpose by making the clearer agent of a flexible material having a glazed or shiny surface, brought and held in pressing contact with the working faces of the drafting rolls, in much the same manner asthe ordinary felt clearer. I have experimented with a great variety of such materials, and all of them having a glazed or semi-glazed surface have proved far superior to felt and kindred fabrics in respect of the features above mentioned, but I prefer tov use the hair side of sheepskin leather which has been dressed with about as much glaze on it as is now ordinarily found upon the leather covers of the drafting rolls of spinning frames. The roll and clearer thus present surfaces of the same material and character to each other, and the operation and efliciency of the spinning frame is thereby improved, as above stated.
Copies of this patent may be obtained for (shown of exaggerated thickness) is formed in a loop with the shiny side 4- on the outside and held or stretched between the staples at each end. The frame is supported or guided above the drafting rolls so that its weight is borne by the leather loops, the shiny side of which rests on the faces of the rolls, as above stated.
Such a clearer is found to collect little or no loose lint or fibers, and needs attention only at infrequent intervals. Such mattter as collects thereon consists mainly of a gray ish powdery dirt, some of which drops to the roller-beam, while the remainder can be easily wiped off with a cloth or brush, being much more readily removed from the hard surface than from the ordinary fabric clearer, from which the lint and dirt must be picked withthe fingers. The new clearer, moreover, keeps the drafting or delivery rolls clean and polished and free from grease, and the yarn spun therefrom contains less bunches or nits than yarn spun from rolls cleared in the old way.
I claim: 7
1. A clearer for the drafting rolls of cotton-spinning and like machines, comprising a clearer frame and a flexible sheet material mounted thereon, having a hard, shiny surface in resilient contact with the working face of one or more of said rolls.
2. A clearer for the rolls of cottonspinning and like machines, comprising a clearer frame and a sheet of leather stretched thereon, the hair side of the leather being glazed and adapted to be mounted in rubbing contact with the Working faces of the rolls.
In testimony whereof, I have signed this specification in the presence of two witnesses.
