CARDlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 229,808, dated July 13, 1880.

V Application filed June 30, 1879.

To all whom it ma/y concern Be it known that -l, 'AIBIATHAR W. DEAN, of Taunton, in the-county of Bristol and State of Massachusetts, have invented a certain new and useful Improvement in Gardin g-Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being bad to the accompanying drawing, forming part of this specification, in

1 which the figure is a perspective view of a portion of a carding-machine, showing the application of my improvements.

My invention relates to that class of carding-machines in which a series of cards or flats I 5 mounted upon radially-sliding rods are employed in connection with a revolving carding-cylinder 5 and it consists in a series of independent fibrous wipers secured to the guide byv means of cap-pieces and surrounding the guide-rods supporting the independent cards or flats, whereby said rods are effectually wiped of dirt or foreign matter, as hereinafter more fully set forth, and pointed out in the claim.

2 5 In the accompanying drawing, A represents the carding-cylinder; B, the independent cards or flats G, the radial arms or rods uponwhich the flats are mounted; D D, the guides for the rods; E, adjustable collars on the rods, 0 and F springs mounted upon the rods between the upper guides and the adjustable collars, and adapted to keep the flats in proper working position, and to retract when lifted for cleaning. I

Thus far described the machine does not differ materially from those heretofore used; but it is open 'to an important objection, which it is the design of my invention to remedy.

In the practical working of the machine it is 40 found that the'constant back-and-forth movement of the rods causes the cotton or dirt and other foreign substances which naturally collect upon them to be carried into the guides, and in a short time clog up the latter, so as to cause the rods to bind and interfere with the proper action of the cards orflats. The rods then have to be taken out and the guides separately cleaned, which operation requires considerable labor and inconvenience and necessitates the stoppage of the machine. To ob- 5o viate this loss of time and labor and yet keep the bearings or guides clean and in good working condition, I employ what I term wipers, composed of woolen, cotton, "or other textile fabric, or of leather, rubber, cork, or other 5 5 elastic material. These wipers may be arranged upon the upper guides merely, or upon both upper and lower guides, as preferred.

In the drawing I have shown three different kinds of wipers-one, W, consisting of a piece of cork having an aperture forthe passage of the rod of slightly smaller diameter than that of the rod and secured to the guide by means I of glue or, adhesive cement; another, W, consisting of a fabric washer, preferably woolen, 6 surrounding the rod and held in place by means of a cap-piece, w; and athird, W consisting of a piece of fabric fitted around the rod and held by pivoted arms a, a.

The Wipers do not fit snug enough around the rods to cause them to bind, but merely exert a light elastic pressure, just sufficieut to remove the particles that have accumulated.

By this simple arrangement the flats or cards are kept always in good working condition, and the machine does not require to be stopped for cleaning, as heretofore.

It will be seen that in my construction each rod may be removed or replaced independent-1y of the others.

Heretofore in this class of carding-machines, in which a series of independent cards or flats mounted upon radially-sliding rods encircled by spiral springs is employed in connection with a carding cylinder, two outer 85 curved and concentric guides for the rods have been used, with the space between them filled with a bushing of wood; and 'I lay no claim to such invention, in which the bushing is employed to form elongated bearings for 0 the rods in their reciprocations, and is not applied to the outer side of the guide to act as a wiper, nor can the bushing for one sliding rod be removed without removing the bushing for all the sliding rods. 5

I claim as my invention The combination, with the frame of the cardby each wiper may be 5 e detached ing-machine having the curved guides D D, without removing the 0mm tantially as of the sliding rod 0, independent flats B, described, and for the purpose set forth.
