NA PETERS, PHOTO-LITHOGRAPHLR, WASHINGTON. n 174 UNITED STATES PATENT OEEICE. ISAAC STEAD, OF PHILADELPHIA, PENN SYL IANIA. IMPROVEMENT IN CONDENSING CARDlNG-ENGINES. Specification forming part of Letters Patent No. 35,114, dated April 29, 1862. To @ZZ whom it 11m/y concern/.V Be it known that I, ISAAC STEAD, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented some new and useful Improvementsin Condensing Carding-Engines for Cardin and Condensin g Fibrous Substances; and I do hereby declare that the following is a full, clear, and exact description of' the constri'lction and operation of the saine, reference lbeing had to the annexed drawings, making a part of' this specification, in which- I `ignre l is aside view; Fig. il, an end view. Fig. 3 is an enlarged sect-ion oli' (flotter-shaft and traversing-cam. Figs. l and i5 are enlarged sections of the revolving toot-hed fiber-separa tor. Fig. 5V is an enlarged section of the collar-doffing roller. My improvements belong to that class of cards called corulensers.7 To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation by referring to the accompanying` drawings. A is the cylinder, and (I the frame, which are made in the ordinary manner. I3 is the dofi'er, which I propose to make larger than than the usual size. For afortyeight-inch cylinder I use a thirty-six-iuch-diameter doffer, the doffer being thirfysix inches wide on the face and covered with a continuous piece of wire fillet. I now divide the face of the doffer into seventy-two part-s, (two to the incli,) or as seen in Fig. 2, which is divided into twenty-four parts. The cylinder delivers the fibers to the doffer, covering the whole face. It is necessary that the fibers should be separated at the points where the wire is divided. I do this by the revolving` toothed fiber-separator I, which is constructed as seen in Fig. o'. M is a shaft turned to lit` the holes in the collars N N and circular plates L. At I the collar is forged fast and turned true. One of the circular plates is slipped on against the collar, and then one of the collars N turned to suit the width of the rings or divisions on the doffer; then a second circular plate, and so on, till you have as many circular plates as you have rings on the doffer. The whole is firmly fastened by the last collar, which has a thread cut in it and a corresponding thread cut on the end of the shaft. The last collar acts as a nut and the whole is screwed tight. The circular plates can be made of sheet-steel about one-sixteenth of an inch in thickness. The teeth should be about eight to the inch of circumference. The fiber-separator is hung in bearings in the plate R, Fig. l. Thisplate is hung on the dolfer-shaft and steadied by the pins a a d. rlhe fiber-separator is set so that the saws or pla-tes will pass between the rings on the doffer and separate the fibers. All the fibers that the separator takes :from the doffer are collected by the stripper S, as seen in Fig. 1, and carried back to the cylinder. The stripper is a plain roller covered with wire fillet and set so as to work between the fiber-separator and cylinder. Having described the construction and operation of the fiber-separator, I will now describe the construction of the collar-doffing roller K, as seen in Figs. 2 and (section) 5. I make a pla-in shaft, as seen in Fig. 5. The collars o o o are made to fit tight on the shaft K. By referring to Fig. 2 it will be seen that I have four rollers and six collars on each roller or shaft. The collars o o o can be made of wood and covered with cloth, or they may be made of metal, leather, or india-rubber. To operate my doiin`g-roller on a thirty-six-inch wide doffer with seventy-two rings or divisions, I make t-he collars one-half-inch wide and eighteen collars on each roller or shaft. I set them as seen in Fig. 2. The first collar to the left on the bottom roller takes the slubbing off of the first ring on the left of the doffer, and the first collar on the next roller above the slubbing off of the second ring, and the first collar on the third roller the slubbing off of the third ring, and the first collar on the fourth roller the slubbing off of the fourth ring, and the second collar on the bottom roller the slubbing off of the fifth ring or division of the doffer, and so on, as seen in Fig. 2. The doffing-rollers deliver the slubbing to the rubbers in the usual way. Should it be desirable to make coarser work and only use three spools, one dofng roller can be dispensed with by putting fty-four divisions or rings on the doffer and making the collars on K the doffing-rollers to suit the width of the rings on the doffer. The fiber-separator inust also be adjusted to suit the rings on the doffer. The dofng-rollers and fiber-separator erm be adjusted to suit any kind of work, coarse or line, with two spools 4or more. At those points on the doier where the fiberseparzitor separates the wire the dofer will not take the iibers from the oylindein Y To renr edy this and prevent the Iibers :from colleoting,` at any part of the cylinder, I cause the doffer to traverse the face of lthe Cylinder. In Fig'. 2 it will be seen that the doffer libersepamtor and dofng-rollers are all Conn eeted or hung on. the doffer-shaft by the plate R. On the end of the dolfer-sh'aft, Fig. 2, is the traversin g-emn E, (more plainly seen in Fi 3.) The stand F is rinly fixed to the card-frame, and as the dofer revolves the @am E @mises the doffer to traverse the ffice-Cylinder for the above-described purpose. I Claiml. The revolving toothed Cylinder in Coinbination with the doiing cylinder B oi' :t con d en si ng @aiding-engine, as forming` a fibersepairzrtor, as described in. my specification. 2. The stripper S, in combination with the revolvil'ig toothedcylinder I, for the purpose of removing' the fibers which may collect on the teeth and omrying iheni baek to the main cylinder, as described in niy specification.
