WOOL-BURRING MACHINE.

To all whom t may concern Be it known that I, WILLIAM CUNDELL, of Paterson, in the county of Passaic and State of New Jersey, have invented new and useful Improvements in Machines for'Cleaning Wool and other Fibrous Substances, and that the following is a full, clear, and 'exact description of the principle or Y' character which distinguishes them from all other things before known and of the manner of making, constructing, and using the same, reference being had to the accompanying drawings, making part of this specification, in which- Y l Figure l isa longitudinal elevation of the machine; Fig. 2, a front elevation; Fig. 3, a section through the cleaning and the shear- -ing cylinders; and Fig. 4, separate views of the rings of teeth and the plane rings inter-l posed in forming the cleaning cylinder. V The same letters indicate -like parts in all u .the figures.

A machine for cleaning` wool has heretofore been made with the cleaning cylinder composed of metal rings with the teeth formed by `cutting into their periphery, so that the points of the teeth shall not project beyond the general periphery of the cylinder thus formed, the spaces between the several rings and the spaces cut out to form the teeth being so small as not to admit bursl or other coarse impurities; but in thisthe space cut out to form ,the teeth was made much larger within that at the periphery, the defeet of which is that a large quantity of fibers accumulate within this space than can be drawn out and thus the machine chokes. The different rings were so arranged as to have the spaces between the teeth of one ring correspond with the middle of the teeth of the next, which I have found prevents the free reception of the fibers. The object of the first part of my invention is to avoid these defects which I do by making the spaces or slots cut out between the teeth no wider at bottom than at the periphery which efl'ectually prevents choking, and delivers the fibers to the card with facility; and I facilitate the reception of the fibers by arranging the teeth ofthe several rings in a line whether parallel with the axis of the cylinder or diagonal thereto. In the machine referred to, the cleaning cylinder was so combined with a carding engine as to take thev place of the tumbler and have the carding cylinder to take the fibers directly from experiment to be defective; this I have much improved by introducing the cleaning cylinder between the feed rollers and the tumbler that takes the fibers from the cleaning cylinder to transfer them to the 'carding cylinder this constitutes the second-part of my invention. And linallyin the machine referredto the burs,' motes,`&c.', were sheared or cleaned off by means of what istermed the cleaning roller whichfconsists of longituf dinal blades or strips projecting from the surface of a 4cylinder in lines parallelwith the axis. This I deem to be defective because they act byintermission and entirely the cleaning cylinder which I havefound byy Vvl acrossthe whole length yof the cylinder aty once. My improvements in'this part of the 1 machine` consist in placing these guardsw cleaners or shears diagonally, on the surface of a cylinder, or in curved lines so as to act continuously on the cleaning cylinder; and

also in making'them of sheet metal bent in.,V the form of semi-cylindersy inverted andsol.-` dered to the surface of'a hollow cylinder so thatftheir edges shall come together to form the blades, cleaners, or shears, which are thus braced in oppositeydirections.' f

In the accompanying drawings (A)v represents the carding 'cylinder of a cardingen gine, (B) the tumbler, and (C) the stripper, all constructed 'andarrangedfin the usual manner of carding'engines; The feeding rollers and aprons areremovedsufhicientlyfrom the tumbler to admit between them the cleaning cylinder (D) vwhich receives the fibers from the feed apron 'and rollers and transfers them to the tumbler to i be carded in the usual manner; but before passing to the tumbler the fibers are acted upon and stripped of the motes, burs, and other impurities by the rotary shear guard (E) which strips off all the impurities that project above the surface of the cleaning cylinder, as indicated by arrows, and the` teeth on the tumbler ypass the` teeth of the cleaning cylinder, (moving in the samedirection) with suficient'velocity to take'the Y fibers from the teeth of the cleaning cylin-' der and transfer them to the card inthe usual manner. Y

The vcleaning cylinder fis composed of a series of metal rings (e) of teeth slipped and secured on an included cylinder (f) with rings (z') made ot flattened wire int-en.

posed. The teeth are formed on the rings (c) by cutting yin slots tangential toa circle of' about two-thirds the diameter of the pe'- riphery of the rings, theV sides of each-slot@ being parallel, or nearly so, which `prevents the fibers and other impurities from accum-v ulating insuch `quantities wit-hin ,the slots Soas to choke them up, but not sufficiently wide to-admit motes, burs. &c. And the series of rings (e) should-be so arranged as to have the slots in a continuous line either parallel with the axis or diagonal thereto. The slots shouldl also be made of greater depth than the projection ofthe teeth beyond the periphery ofthe intermediate rings Vso that as t-he points ofthe teeth wear they canbe' sharpened and the same length of tooth retained by grinding or otherwise reducing the diameter of the rings of teeth and the spacing or intermediate rings. The usual thickness of these rings is about one twenty-sixth Vof an inch so as to have about thirteen of each kind to an inch; they are secured `and held on the included cylinder `by beingclamped between a permanent lanch (g) Aon one end of the cylinder, and a movable one on the other end secured by a key or screw in manner well known to machinists. Y

The stock of the rotatingshear guardv is a hollow cylinder made of sheet metal with headsto form the connect-ion with the shaft; and to the periphery of this cylinder are secured t-he guards or shears (n) which are made of sheet metal semi-cylindrical, with the-convex part soldered or otherwise secured to the cylinder with the edges pro- "jecting at equal distances from the periphery. These are arranged around the cylinder with the edges placed against and soldered to each other, two edges thus brought and secured together forming one shear or guard. `Theyare arranged as represented in Fig. 2, each inclining in opposite directions :trom` the middle of the length of the cylinder so as to act diagonally from this point in either direction and thus clear off V'the'1notes, burs, &c., more regularly and effectually than when placedparallel with the' axis. Or, Iplace them either in a zig-zag line, as represented in Fig. 5, or in curved( lines as in Fig. 6, these two acting on the same `principle as the first example, and

therefore introduced simply to show that theV vsame principle can be variously applied.` i.

As the carding part of this machine is constructedand operates 1n manner similar to the common carding engine 1t 1s deemed `unnecessary to give a description ot it.

l/Vhat I claim as my invention and desire;

`tosecure'by-l'netters Patent, isy y 1. Making the spaces or slots between the,

teeth offequal width, from the point to the bottom of the teeth, when this `is applied to teeth the peripheries of which are` concentric,

so that when the rings of teeth are all put together the outer portion of the space shall be of the same width as the space within, and

the surface of each tooth from point to back `shall be a segment of a cylinder and concentric, substantially as described. y

2. I claim making Vshears or guards for clearing oli' the impurities, of sheet metal bent in semi-cylindrical forms and connected together by the edges and with the included cylinder by the `convex surface, substantially as described.
