CARDING- OR STRAIGHTENING THE FIBERS OFCOTTONL Specification of Letters lfatent. Patented Feb. 14, 1922.
Application filed August 12, 1920. Serial No. 403,005.
I '0 all whom it may concern:
Be it known that I, DANIEL E. MOLLOY, a citizen of the United States, residing at Fall River, in the county of Bristol and State of Massachusetts, have invented new and useful Improvements in Carding or Straightening the Fibers of Cotton, of which the following is a specification.
This invention relates to certain new and useful improvements in carding or straightening the fiber of cotton, and relates especially to what are known as revolving flat cards used in the textile art for carding or straightening the fiber of cotton.
The primary object of the invention is to provide means which will act upon the cotton passing into the machine under the feed roll so as to cause the fibers to be straightened by what is commonly termed the licker in. r
A further object of the invention is to provide means of the type mentioned which is adjustable, and which will operate effectively and with certainty to function as above described.
Briefly the invention resides in the employment of a bar or the like having a sharp or knife edge which is adjusted to such pointthat the cotton passing into the machine under the feed roll will be drawn across the sharp edge of the metal bar or knife and thereby cause the fibers to be straightened by the licker in as the latter draws the cotton over the knife edge.
Further and other objects will be later set forth and of themselves manifested in the course of the following description.
In the drawings:
Fig. 1, is a fragmentary side elevation, partly in section, showing the present invention in position on a carding machine; and
Fig, 2 is a detail perspective view of the knife or cutting bar.
In proceeding in accordance with the present invention it will be understood that the rolls depicted in the drawing are in practice supplied with the usual card cloth, and that the machine itself is otherwise of the usual structure employed in the cotton mills.
Accordingly it will be understood that the roll of cotton known as thevlap is supported on the lap roll E and passes under the feed roll D to what is commonly termed the licker-in, the latter being designated A in the drawings. From the licker-in the cotton is carried downward and over the roll B, the latter acting to remove the short fibers carried into the machine by'the licker-in A, and the cotton is then stripped from the roll B permitting it to pass to the main cylinder C, from which latter it is stripped and operated upon by the various flats until it finally reaches the opposite end of the machine where it is doffed or removed from the main cylinder and passes out of the machine.
The present invention particularly resides in the use and combination with certain of the above parts now to be described, of an elongated bar 1 which is beveled along one edge to form a cutter or knife'2. This bar may have slots 3 through which bolts 4: pass to rigidly secure same to the usual feed table, the bar being preferably disposed beneath the table. As depicted in the drawings the knife edge is disposed adjacent to the periphery of the licker-in, and can be adjusted toward and away from same as is obvious by means of the bolts and slots, the adjust ment being such that the cotton passing into the machine under the feed roll D will be drawn across the sharp edge to straighten the fibers.
In operation the roll of cotton is supported on the lap roll E and passes under the feed roll I), and is then drawn by the licker-in A across the sharp edge of the bar or knife, so that its fibers will be straightened, following which the cotton is carried downward over the roll B, whereupon the latter removing the short fleece from the licker-in whereupon the cotton passes to the main cylinder C, from which latter it is stripped and operated upon by the variousflats until. it finally reaches the opposite end of the chine where it is stripped or removed from the main cylinder and passes out of the machine,
From the above it will be seen that the expedient is simple and positive in its action and that it can be applied to existing machines by the mere formation of bolt holes in the feed table.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is In combination with the feed roll, feed table and lioker-in of a carding machine, a
knife having an approximately horizontal disposition secured to and beneath the feed name to this specificationin the presence of table 1with its effective edge presented to the two Subscribing itnesses: perip 1631' of the lieker-in and in such close relation hereto so that foreign substances v D L Q 15 will be removed from the lap and combing or Vitnessesz' straightening of the fiberswill oceur. E. TO0MEY,- In testimony whereof I have signed my J. H. MILLER.
