TO ALL WHOM IT MAY CONCERN: t t

Beitlrnown that I, DARIUS Gorrgof Pawtucket', `in the county of Providence, and Stateof Rhode Island, have invented a'new and useful Improvement in Machinery for Picking andSeparatingCotton-Waste; and'I do hereby declare that the following is a full, clear, and. exact 'description of the' same, referencebeing hadto the accompanyingdrawings, mahing partof this speciicatiomin which* l Figure 1 is a side elevationrand section of my improved machine. Figure2 is'a full-size view of one'oi` lthe clatv-hook teeth, hereinafter mentioned. Similar letters indicate like parts in both the figures. c

The mater-,ial-feottomwastewhieh my improved machine is designed te prepare, consists of themass of l spun cotton and` thread and loose unspun cotton and roving, which accumulatesin cotton-mannfactories. lIt; is collected in considerahle quantities, and picked open, and thennspnn cotton, or'SOftWaSte, separated from the yarn and thread, the former to he manufactured into low` grades of cotton goods, wedding, and-such like fabrics, and the latter to he used for cleaning machinery, and for other purposes.

And the object-of my improved machine is to facilitate the picking and separating oi' this material, in order l the-better to prepare it for these purposes, and -the more 4eigaerlitionsly. I'

My invention consists, first, of an enclosed cylinder, armed with stout claw-lieoited teeth, so constructed and set in` the periphery thereof, that when. the Waste is properly presented by suitable mechanism, While the cylinder is revolving rapidly, the bunches of spun yarn and thread will he caught by the revolving teeth, and "disentangled, and iveund uponhthe cylinder, while the un'spun portion of the lwaste will be separated and thrown t'il' from the cylinder and dischargedfrom the machine. Y

, My `invention also consists in constructing the casing or jacket which en closes the said'cylinder with. an

opening across its Face, and a door forclosing'the same, for the purpose odiscllarging the soft or unspun waste, and of doing orstripping the lap of picked waste from the cylinder when the teeth become filled. 4 v lMy invention also comprehends a device for feeding the rough waste to the toothed cylinder in such a. manner that, while the massof waste is held in a sort of throat formed between the feeding-device andthecyl-- inder, the portion oi' the yarns and threads .which is caught hy the revolvingvteeth may he easily drawn out of the mass, Aand ivound parallel to each other on the cylinder, instend of breaking and tearing the mass asunder, and lbreaking it's libre.. This device consists of a feed-roll, set with stout inclined pegs or teeth, and a shell (so called) for'conductfing` the mass of waste to the cylinder, and e. stripper or retaining-bar, (so callech) consisting of a stili, permanent'bar'ol` metal, generally suspended 'between the feed-roller and cylinder, in such a manner thatphy slowly revolving thefecd-roller, the-waste is carried under the shell and heneaththe retainingbar or stripper, where it is delivered Vtothecylinder-teeth, which, in revolving, catch and draw the threads or .spun portionacress the retainingbar, while the mass is confined or held hack by the teeth of the @one slowly revolving feed-roller; and thus the portion caught is picked and drawn out of the mass, and woirr'i'dnpon the cylinder intheform of a lap, i e l v To enable others skilled in the art to make" and use my invention, l will proceed te .describe the same.

In the said drawings, B is the cylindemwhich is mounted .in a stent frame, F, to revolve on the shaft D, in suitable boxes upon cach side, and mis the casing, `in whiclivthe eylinderis completely enclosed, having an opening, H, that is closed b'y the door E. l l

The periphery of thecylinder is set with rows of stout steel hooked teeth, l), in such a. manner that their points shall travel foremost in a line coneentrim'or nearly so, with the surface of the cylinder..

G is the feed-roller, which 'revolves quite slowly, by motion communicated bythe hand l't,-.'rom-the pulley on the cylinder-shaft D, to the pulley I, and thence, through the 'pinion g, to the gearf (represented by dotted lines) on the end of the feed-roller shaft. l I i 'The `surface of theiecd-roller is set with ro'ws ei short, inclined` pegs' or teeth, t, which are inclined in the v y opposite direction from that in which the said roller revolves, as indicated by 'the arrowinarked thereon.

The shell S is arranged over the feed-roller-threughout its length, affording a suitable space between it and the roller, for the passage of the mass of the wasteby the action of the. roller, and'extends down between the vfeed-roller and th; cylinder, to form the stripper or retaining-bar R, which extends into the throat or space between the cylinder and roller, midway between each, along the entire face'of the same.

The rough waste is spread evenly on the endless apron N, that is stretched over the two rollers C, which revolve slowly in the direction indicated, which movement, being imparted tothe apron, movesthe waste thereon forward, and delivers it to the feed-roller G. Here the waste is brought into contact with the pegs or hooks t, which carry tl1e.u'aste under the shell S, and thence into the throat T, beneath the stripper R. Here the waste is presented to the action of the cylinder-hooks L, by which portions of the waste are caught and drawn, by a short turn round the stripper R, which, together with theinclined pegs or hooks t, detains the mass of thewaste, and holds it with sufiicient firmness to permit the hooks L, with their more rapid movement, to draw out the yarn and thready waste in the manner shown at A, iig. l, and strip it upon the hooks, and finally wind it upon the cylinder as it revolves. 'i

It will be readily understood that the method employed or described, of holding on to thel waste by means of the hooks t, and the sharp turn or big-ht formed in the waste bythe stripper It, while it holds the mass firmly, it permits thc shreds or strings ofthe waste to render around the hoolis t and the stripper R, and as Well around the hooks L of the cylinder, and that in this way-the shreds or threads are drawn out, or, as it were, disentangled, instead of being torn asunder and broken into shcrtstul; and it is this peculiarity of the operation ofthe feeding-device whichdistinguishes it from all others with which I am acquainted, and te which the desirable result of preserving the fibre or stapleof the waste from being broken to any injurious extent, is mainly due.-

I have heretofore employed a pair of iluted feeding-rolls, between which the rough waste passedfand was delivered to the cylinder-hooks, but it was found that such rolls so griped and confined the waste thateither bunchesbt` unpicked waste were wrestcd by superior force fromthesciuted rolls, or that the waste was broken off short, and the original length of fibre or staple destroyed, and the quality and usefulness of the waste pro portionablT impaired. l l Y The unspun cotton and roving which exists in considerable quantities in spiuners waste, so called, is in small clots or bunggies, and is of a lighter or more volatile nature than the bulk of the waste; so that while the hooks L are admirably adapted to pick open and untangle the yarn and thread constituting the libre ofthe waste, this soft waste escapcstheir action almost entirely, and, to the contrary, it is thrown bythe fanning action of the cylinder against the surrounding easing, and is whirled or carried round with the cylinder until ,it escapes at the opening H, in the casing provided fr that purpose, as shown in iig. 1.

The shape and curvature ofthe cylinder-hooks L are ot` great importance tothe successful operation et' the machine, as herein described, for while the shape of hook shown in fig. 2 (which is the best shape vand prdportion yet arrived at) willeatch and draw'out; with but little breaking', hunks of spun-waste, and retain and wind the threads parallel to each other upon 'the cylinder, a shorter hook, or one having less curvature, or being straightcr, will simply scratch or. beat the waste instead of retaining its hold, and d raw ont thethreads to some length from the mass. Such hooks, also, for the same reason, are incapable of drawing away the threads and separating them from the cotton, but are rather calculated to reduce the muss of waste to short stuff and mix the tufts ef cotto-.i and unspun material with it. The hook, iig. 2, occupies, aswill be seen, a little more than a quarter of a circle at its inner curvature, which is a desirable shape, and calculated to produce goed results; .that is, the inner surface or curve ofthe claw-hooks which projects from the surface of the cylinder has a true curve., or nearly so, with their points terminating in aplane concentric with the cylinders surface, and, if con-A tinued, would describe a halt` circle between these two concentric planes. In making hooks to contain a lap of greater or less thickness, about this proportion should be preserved. Y v

When this machine is used for picking and disentangling spun-waste only, as in preparing cop-waste and other kinds which are without any admixturc of unspun cotton, the door over the'opening in the easing or jacket m remains closed during'the operation, whereby the shorter portions of the' waste, which the hooked teeth do not` catch and retain, are'c'onined inthe space between the casing and the cylinder, instead of being thrown olf; and are ultimately all combined with the long waste, as'it is wound upon the'cylinder, and incorporated with it, and thus preserved to be used-with and for the same purpose as the longer fibres.

What I claim, anddesire to secure by Letters Patent, is-

l. A cylinder, B, armed with claw-hooked teeth, L, so 'constructed thatwhen set, their points shall all travel foremest as the cylinder revolves substantially in'a line concentric with the surfaceof the cyiinder, in combination with the feed-roller G, or other suitable feeding-mechanism, as described.

2.i 4'.lhe combination of the cylinder B,Ias described,'with a casing or jacket', m, constructed with -nsuitabl'e opening, H, and a door for closing the same, substantially as and for the purpose specified.

3. The combination of the cylinder B, as described, with the feed-rollex` G and retaining-bar R, or other suitable mechanism for delivering and retaining hold of the material, substantially as described, while it is subjected to the action of the cylinder, as specified. y i i DARIUS GOFF.
