DEVICE FOR CLEANING THE FLATS IN GARDING-ENGINES.

Application filed February 25, 191 swarm. 279,102.

I (1H- u'llom it may concern.

Be it known that 1, human Dnarnn, a subject of the King of (treat Britain, and resident of liorlw. in the county of Lancaster, jlngland. have invented a certain new and useful lin worcnient in Devices for Cleaning the Fhits in Carding-Engim-s, of which the following dcscription. having reference to the :m-onipanying sheets of drawin is a s 'icciliration.

li [y invention relates to devices for use in removing the fibers, dirt and other waste or ohje'ctionabhmatter which accumulate between the pins, teeth or wires of the clothing fixed upon the flats in carding engines. Usually these cleaning operations are 15erformed by rotary brushes, combs or other devices covered with suitable material, such brushes or the like moving or operating in the same direction or in alinemcnt with the path of motion of said flats. and it is found that the waste 01' objectionable matter is not thereby entirely removed, but is to some extent pressed firmly upon the clothing between the pins so that the lower portions of the latter or those parts thereof in proximity to the foundation in which they are place become covered or surrounded. with substances held firmly in position. My present invention consists in the use or employment of means,

consisting of rotary brushes, which aretravarsed across thei'nachme-or lengthwise the liats instead of as licreinhefore descrihoth,

this traversing of said. cleaning brushes lieing performed automatically, and with the brushes hai ing thciraxes in alinement with the path of motion ofthe flats, or at an a)- propriate angle thereto other than a ri ht angle.

Tn order that my said invention may be readily understood. 1 have hereunto appended sheets of drawings illustrative then-oi, to whi h, by figures and letters, relcrenre is made in the following description.

In the accompanying sheets of drawings, a indicates the main cylinder of the carding engine, and 7) a portion of the revolving flats from the. clothing of which it is desired to remove refuse. As will be well understood. the flats 'bpass over the rollersc, c rand other guiding parts into proximity to or contact with the main 0 linder a, anditis 'during the passage of tlioflnts over the cylinder fa that they become charged .iwith dirt, or waste. f 9

In carrying my invention into effect, I make use of a. brush or brushes (lwhich or are carried by a plate or bearings d such hearings fitting over projecting Apar'ts or pins 0 thitending from a plate yfiXEdOI connected to the sleeve 0?, as by the extensions a, fulcrum pin e", and pinorholt je'". This sleeve '6 is mounted to slide upon a tube c within which rotates a compound -or (low hle acting screw not well, known form hav ing a. fork g fitting tl-IGIBOVBI thQ connection between the fork-g :and thelsleeye a? hein such that said sleeyennd thestuhoi F may he turned around the screw? from the backward and forward across the faces of the flats upon which the two wheels or brushes (1 rotate as said flats over or through the machine. The brushes (I may rest a ion the llatsby gravity or may he supported so that they do not press firmly upon said flats but the clothing thereof merely passes through the clothing of the iiats I) so that they are rotated thereby. To support said brushes and the parts carrying them, l

mount upon the tube c an adpistahle collar m provit ed with a projecting part n i which comes into contact with a part of the bean ing 0 for the screw pathos this projecting part it supports the weightof the extension 5 e and parts carried therelrv. When moving the brushes 4 into the iosition shown in brokenlmes by 1 1g. 1 either the collar 11/ may be adjusted for the part a to again come into contact with another partol the- Q bearing a or i magemake use of a separate sto rpiccei'or this purpose.

he screw: 1/ is rotated in any suitable manor as by the pulley s opeiated.from the pulley a on the main shaft x by the ro'rd or 3 band 8.

The rollers or brushes (iJUIPCOYL'I'Ol with earda'lothing or similar nzaterial and the leading vwheel in each dirertion of trau-rse across the flats I) has the wire portions of such clothing extending in snclr direction as not to act as a cleaner for the flats!) but the clot hing on the other or following roller is arranged of the opposite hand orin the oppo-.

site direction so that it lifts the waste and other refuse from the interstices intervening between thewire of the card clothing: The plato rl s readily reri'iovable from the pro electing parts 6, said plate r]- carrying the p rushes'or rollers d, and by the axes-of said rollers (J not descending below the horizontal plane or below their position in alinelire-fit with the axis of the screw y. these parts may merely rest in position without the addition of extra nuts or fixingparts.

The brushes d may simply travel back ward and forward across the machine or lengthwise the flats, both of them rotating in contact with said flats, or I may make use of means whereby the roller or brush which Q50 is not performing its functions as a cleaner is rtiised out 'of contact with the flats. This maybe efl'ected in any suitable manner. as by thee'mp'loynlent 'of'a rolling weight 11 inounted on or inthe'" late or trough d, a

fifi'jprojeoting part as t at shown in dotted position projects through the slot r e. r

lines in Fig. 5 being mounted on each side of the machine with which a projection r/ of the plate (1 comes into contact, thus at or near the end of the traverse of the brushes :1 in. one direction the contact of these parts will oscillate the bearing (1 and press the roller or brush (I which will during the out traverse be the cleaning hrusln into contact with the clothing on the liats. while when this next traverse of the brushes is completed the other projecting part p on the other side of the machine depresses said bearing (1 so that the other brush is then pressed into contact with the that clothing to perform the cleaning operations during the succeeding traverse.

To enable the brushes (1 to rise and pas over any obstruction they may encounter i may provide the hearings or supports r, with a spring 1/ which allows same to s\\i\ el on the pin. said support being manually held in position by the tixed slip 1/, or other suit able means may be used for this purpose.

1 have hereinbetore described the employ ment of two brushes which perform the cleaning operations alternately. but i mav employ one single brush as shown by Fig such brush efl'ecting the cleaning of the flats inone direction but rotating idly in the op posite direction.

. I prefer to have taie cleaning device travarsed in a direction approximately at right angles to the travel of the flats with the axis of the brush in alinement withsaid path of travel of the flats: however 1 may if desired arrange same to travel thcreovei' obliquely or at any suitable angle to this di" re tion.

in Figs. 5 and 9 l have shown a weighting device used in connection with my invention. The sleeve c" tits over the sleeve w somewhat in the manner hereinbefore described. but

said sleeve is provided with projecting part:

c which form a support or bearings for a cross pin Ii nniunted on a curved part /i which spans a centrally disposed rib This curved part ii is provided with an we tending handle 11* the outer end Ii of which is preferably larger than the other portions and is weighted with lead or the like in order to' perform the dual otlice of a handle and weight. The brushes (I are carried by l-earings (l swiveling on a pin r attached to the curved part 7;. When desired for an purpose the operator may readily raise said brushes 1/ out of contaet with the Hats l) b simply turning the curved part ii on the inlerum pin- II. The weighted handle ii" when the parts are in their normal position. presses the brushes 1) with sufiieicnt force into the card clothing on said flats Ii.

Instead of employing the brush or brushes acting as a cleareror elearers in onedireetiim only. i may employ a single brush which each side-of the carding engine is rever. ed in direction so that it is capable of act'- g as vying hmn'ings for said brnshegs, and means for autaniatimilly traversing saldtlever arms and hearings from one side of thalnuvhine to the utla-r and antnmatically traversing said la-arings in tho nppnsitc direction.
