may concern Be it known that I, OsoiinM. octetsa citizen ot' the UnitedlStates. and a resident of North Eindover, county Of ESSGX, State or lilassachusetts, have invented an Improve-Q ment in Machines for Picking and Burring W0o'l,;Etc., of wlnch the following descrlp tion; inv connection with the accompanying drawing, is specifi.cation,'.like characters.

on the drawing representing like parts:

This invent on relates to a machine for pic-king and burring'wool' and similar fibres acting to straighten out the; fibres and re- 'IHOVG therefrom the dirt, burrs and foreign substances associated therew1th.

The object of the invention is to provide an improved means for insuring the renoval'of the burrs and preventing waste of fibres I The object of the invention is more particularly to provide in combination. with such a machine a ro'taryfbrush and guard plate so positioned and arranged as to re.- pass through the curring operation burrs knocked out and carrying fibre.

These and other objects and featuresof the invention will appear more fully'froni the accompanying description and drawings and will be partlcularly-pointed out in the claims. v p i In the drawings; Figure 1 illustrates diagrammatically in general side elevation afainiliar' type of picking and burring machine having embodied therein a preferred form ofthepres-v ent. invention Figure 2 is a side elevation partially in latesto but one, although an important step.

or feature of the b urring operation it is necessary only to illustrate and describe in detail those parts of the: machine particu larly concerned with the present invention. Figure 1. shows the entire machine in adiagrainrnatie form and itwillbe'recognized by those'skillecl inlthe art as of affaniiliair type. Such a "r achine in general comp-rises a franie and casingl en. losing all theworking parts. At the adinission'end ofthe machines endless conveyor2 is inountedland driven. The niass'offivool or oth r fibre'is deposited on this conveyorand carried thereby intothe bite of a. pair of feed and separatingroIlsB. The fibre is takenlironi these:

[ olls by themain beat-er cylinder revolving I on the shaft et nside of a cylindrical cage This beater cylinder usually coinprises' spider-like heads 5, partially shown indetail in Fig. 2,.and on the. pe-riphery'ofthese heads areusually n ounted parallel spaced slats 6 carrying rows of teeth '1 pro ecting in the direction of rotation indicated by the arrows. These teeth seize the mass of fibre.

from the rolls3. During therot-ation o f'the' beater cylinder the heavier dirt and foreign substances drop between the slats into the cage and fall out at the bOttODIWhllethe lighter dirt and dust are. sucked out from the cage a suction top of the casing. y y f At the side oftl fe beatercylin der opposite thet'eed is' nounted a rotary burring cylinder 9 This cylinder rota es in a CllIQCtlOaIl opposite to that of the main beater cylinder and is provided onits exterior with rowsof teeth 10 pointing in the directionof' rotation of the burrin'g cylinder and generally formed in the periphery of parallel annular steel blades spaced throughout the length 0t the cylinder. Theperiphery of this burring cylinder is sufiiciently closeto the path travelled by the teeth-7 of the main beater cylinder to cause the fibres to be taken by the burring' cylinder from the main beater cylinder and to lie in a baton theperiphcral sur face of the burring cylinder. i v

A rot-aryburr guard 11 is mounted peripherally adjacent and usually beneatl1,the

V burringcylinderQ. This burr guard is'p-ro vided on its periphery withuradially pro- 9; steel blades 12. The burr guard rojectin tates at a high speed and in the opposite di- I rectionto theb-urring cylinder. Its funcfan 8 mounted the p i tion to, knock off the' burrs and foreign substances lying on the periphery" of the burring cylinder While the f bres remain held in the teeth of the burr ng cylinder.

justahle the The burr guard in hearingblot cylinder and dischargedironi' the machine usually b a rotarv-brushlzi revolvin in a r they are to be understood as indicatingthe' direction opposite to that of thelast hurring Lylinder. 7 I Z hen the burrs are knocked out from the hat of fibre by the burr guards, and particu- .larly in the case of the burr guard such as 11 first acting uponthe fibrefthey frequently carry with them more or less fibre which is wasted or requires a separate operation for its removal. The present invention acts to permit. such burrs it free from fibre, to drop out of the machine but, if carrying fibre, acts to repass them through the hurringg op eration so as insure the saving; of this fibre.

While the invention may be applied to any or all or". the pairs of cooperating burring cylinders and burr guards it is especial'ly useful'in connectlon with the burring cylinder and burr guard first acting upon the fibre after it passes from the main beater cylinder and it is consequently illustrated in the preferred form in thisbosition. While terms such as upper and lower and similar terms are herein used for convenience relationship the elements and not as re strictive.

In the preferred ei'nbodiment of the inven-i tion a cylindrical. rotary brush 16 is mount- 7 7 ed in the angle between the main beater cylhinder and the burring cylinder 9.

v n V This brush is preferably formed as illustrated of tufts of bristles so that its periphery presents substantially continuous surface of bristle points. The peri 'ihery ot this brush 1s so positioned-that 131$ sufiiciently ad acent to the toothed periphery of the burn mg cylinder 9 as to press the fibres between i the, teeth of thel'iurring cylinder leaving, the

burrs and foreign substances on the surface.

The periphery of the brush is alsoso positioned that the teeth 7 of the main beater cyl nder in their travel past the brush may se ze burrs carrying fibre and held on the ,sur'tace o't the brush. The perish rv of this brush rotates at a slowe" the same direction as f teothed periphery of the bllI'IlDQ cylinder.

'mountedjat its ends 1 is transterred from the bnrring cylin-' n the final burrin'g" d than out in The position oftherotary brushlG to secure the desired results is preferably sea cured by making the bearings carrying the shaft 1.? of the brush adjustable in two directions herein shown astirst in a direction radially of the beater cylinder and sec nd in a direction transversely of the plane of the radial adjustment: so that as a result the brush is adjustable toward and from the peripheries of both the main beater cylinder and the burring' cylinder. The adjustment of one of the bearing blocks 4 J2 h' 3 1 q i8 ior the shait Lt shown in Figure 0.

The bearing block l8'is there shown moruu' ed on a bracket ls liiy means of a bolt passing through a vertical slot in the t-el te 'caljarnrqt ofthe bracket. *T he opposite cm} of the block 18 is provided with a set s rew 22 threaded therethrough and abuttinrfa surface 23 on'thetrame 1. tThus by loosenmg the bolt and adjusting the set screw ZZthebea'ring block may he raised and lOVF ered with' respect to I the surface 23. This surface is shown as extending radially of the main ,heatercylinder and the bracket 19 together with tie lower end of the set screw 22isslidable along this surface to give the desired radial adjustment. As a means for effecting the radial adjustment a set screw 2e is shown threaded into the bracket 19 and: journalled in a bracket 25 secured by a' b olt 26 to the frame.

It willnow be seen that the burr guard ll.

is mounted the angle of diverging travel between the burring cylinder 9 and tlie'brush 16 with its peripheryrot-ating 1n the opposite direction to the burring cylinder, but

as the periphery of through slots in the trains and the bases 28 are horizontally adiustable on the brackets by means of .bolts 31 passingthrough slots inthe brackets Thus the uart plate is adjustable to vary the distance between its upper edge and the periphery of the barring cylinder and to vary the space between its bottom portion and the hrush periphery.

An auxiliary guard plate 32 is mounted beneath the brush spa ed from the 'main guard plate and is vertically adjustable toward and from the brush by means of the setscrew passing through a slot therein and into the frame.

Thebrushand the guard plates are so positioned, by means of the adjustments provided, that the burrs knocked off vfrom the iii 1 ron-27 iibrc on the ljlll'flfll'lf cylinder by the burr "d ll are thrown over the topjotthe plate 27; and against the brush 16. at are tree from fibre slide down the curved surface otthe guardiplate 'Q'UfllCl plate is adjusted closer;

and drop out through the-bottom or through the opening; provided b ween the main guard plate and thc auxiliary guardgplate 39, burrs that still carry fibre-clinginose ing to them are caught'by the brush and, the

'usln are rolled around by the-lbrush and n nany cases the fibre is stripped'from hem brthc brushaiso'that they'are freed from fibre and drop outat the bottom! 'ihos ct fibre still cling to the brush and are carried around and repassed through the burroperation. With the brushlocated in the position shown in Fig. 2 such burrs and ibre are seized by the teeth of the main beater cylinder and carried around and transferred to the burring cylinder to go through the operationagainj Thus it is practically impossible for burrs to pass through the machine and be discharged therefrom carrying fibre and it is practically insured that the fibre shall be stripped or removed from the burrs.

The adjustment or" the upper edge of the guard plate 27 toward and from theperiphery' of the burning cylinder depends upon the'lnnd of the stocklbeing acted upon. If the stock is light the guard plate may be adjusted'further away to prevent the fibre being carried down to the right of the guard while if the stock is heavy the The burr guard acts like a fan and if thejstock were too light the fibre would carry down to the right of the guard-which would obviously be obgectio'nable.

The brush as has been pointed-cutie preferably made of bristlesso inserted as to glve a continuous surface containmg a very large number of pointed ends per-square inch, a

much larger number thanris yet commercial in a wirebrush, but the invention is not'to be restricted to the particular kind of brush so long as it performs the desired function.

Having thus described the invention what I is claimed as new and desired to be secured by Letters Patent is: p
