Application filed April 23,1920a Serial No. 376,059.

To all wi l-0m it may concern Be it known thatl, ELLIS R, BROOK, a

citizen of the United States, and resident of Bamberg, in the county of Bamberg and State of South Carolina, have invented certain new and useful Improvements in Thread-Board Cleaners for Spinning-Mia chines, of which the following is a specification. v

This invention relates to means for clean-,

ingthe threadboard of spinning machines I and is in the nature of an'attachment which ing the device on spinningmachines and its Y continuously back and; forth over and. in

' contact with the surface. of the guide board.

and the hingedthread guide extensions from one'end of the guide board to. the other across the machine, collecting and removlng the fine lint and dust which tends to-collectthere. The'purpose of the invention is'to simplify and improve the construction whereby the desired result of cleaningis secured'moreperfectly while at the same time thecost and trouble of manufacture, thework of installliability to get out of order are'reduced.

"The novel features of construction will be apparent from the'following description and. claims taken in connection'with' the draw-' ings. V

1 In the" drawings, e V Figure 1 is a planview spinning machine having my invention applied thereto I direction of movement of the cleaning de-V vice, and

O'f Flg. 2, but showing the-operating cams and clamping arms in full lines.v

- It has not been deemednecessary to show in the drawings many parts ofthe spinning machine towhich my invention is applied since the structure, arrangement and opera-" tion of suchmachines are well knowntand will beunderstood and itis necessary there fore to show only so much of the "old machine as will make clearhowmy' invention 7 is applied to it. In the'drjawings10"repre sents the thread board' which carries along one edge the hinged member's 1l:'-p1-ovided of the thread board and thread guides. of a known form of Patented Mar; 1, 192 1.,

with the wire looped entensions'tlfz I ceive the thread passingflthrough'thedrawlng rolls 13. .As. is well knownrthe thread board 10 is secured to the edge of the main frame 14: of the spinning niachinei- My invention includesa brush l51eirtend-3 mg transversely across the thread board 310 ii and partlyover the extensions 11 and.- pro-' vided wlth downwardly projecting bristles 16 making contact ewith the surface" of the board and extensionsand this brush or clean-C ing device is; moved 'longitudinallyfof the.

board from endztoen'dg thus removing lint and otherim'aterial which may collect on-the surface; The, means for movingthe -e1ean+ ing device orbrush continuously in its re'cip' I rocatlonsfromone side: ofithe'machineto the other along. thethread board.'includesan endless belt or cordf17' passing around 241:; M

loose pulley at one endnand a pulleyil9 "at the other end 'of-the thread board, the: inter- I mediate portions of the cord or belt-10f course being 7. parallel and rather close" toe? gether. The pulley: 19 is. driven throng-ha; shaft 20 and bevel: gears. 21,? 22 anda beltwheel 23 which may be connected by belt 24 to "one of the rotating shafts oi the spinning 'machine so as to constantly drive the pulley 19; Adjacent the driven. pul1ey 19 there are two loose pulleys25 which bear on theo'uter" margins of the belt or cord abringing' them closer together than they Would'beif drawn straight from the'pulleyand a pair of simi lar free pulleysareplaced-adja'cent the loose pulley for the same purpose on -the other;

sideof the 'machine.*-A housing'27lpriefera v.

ably made of thin. metal is-secured"tothe thread board, longitudinally from; one side" 7 of'th'e' machinet'oithe other: andjis sub'stan? V Fig. 2 is a vertical section taken in the tially rectangular in section -lwilth a? 'slot' inthis hOuSinganclis-thus largely protected from fiber and dirt, This'housing occupies Opening '28. in the -top and the cordon belt p Z 17 passes long tudinally across the machine' Fig. 3 1s a cross-section on the line 3-1-3- portion and is'thus belowthe lanushimechathe housing-27 so as to slide freelylongilcord- 17 passes "within this housing 29 im tudinally therein andisrigidly secured tov the-solid member of the brush 'l 5- 'by' suitable means such as: the I- fpOSt30f 'The', belt or;

a' position between th'eisections of bristlef extending downward from the brush top brush, which slot serves as a guide.

serves as one part of the clamping means for connecting the cleaning device orbrush 15 to the belt or'cord. On the upper face of the brush 15 there are two-

posts

31, 32 having mounted therein ashaft 33 which is rotata- 'ble and which carries two

cams

34 and 35 rigidly'secured to it so as to turn with it. Each cam has rotary connection with the circularly bent end of the movable clamping strip or member36 and that clampingmember extends from the cam downwardly at an angle-through a slot 37 in the top of lthe e lower end of the clamping arm 36 extends through the slot 28 in the top of the housing 27 and down to a point just above the cord or belt and is there bent toform a downwardly facing bearing surface 38 adapted to bear downwardly-pressing the cord against the inner. lower face of the housing 29 thus clamping itto the brushor cleaning device. Itwillbe observed that" there is a movable clamping arm for each side ofthe cord or belt and that they are inclinedat different angles.- The camecc'entrics on which these movable. clamping arms are mounted are so arrangedthat when the greater. diameter of the eccentric is approximately in line and on the sameiside as theclampingarm in one cas'egthat; arm willkbe pressed down into clamping position while the eccentric for the other arm will at that timeihave'. its

:greatest diameter out of lineIwith its clamp ingmember and thus thatmember will be raised from clamping position. Itzis of course necessary in moving? the brush or cleaning, device from. one side of the machine ,tothe other that it shall be clampedto oneside of the cord and to make it automatically stop andstart areverse movement backto the otherside of the machine, itis necessary to release the clamp on one side and apply thatontheother side. In my device this is done by means of the'extensions 39, 40 rig-v idly secured to the eccentricsor the shaft;

, and so arranged thatthe'one on the forward side of movement'will be in substantially a horizontal position andwill strike aninclined abutment 41' as the brush reaches one end of the threadboard and this abutment willraise the arm 39 turning-the two eccen-' 'trics releasing one clamp and applying the other automatically. I

have shown this'abutment for-effecting the 'reverse in the clamps only at the driving end "ofthe thread board, but it will be understood that there is a similar arrangement at In- 7 the drawings I the other end.

Having thus described my invention what is claimed asnew and desired to be secured by Letters Patent is r {1.- In a cleaning device boards ofaspinning machines the: combination with an endless belt extending over said,

thread board from one side of themachine to for at." thread the other, means i for driving said belt, a I

as to disengage one portion of the belt and engage the other portion for the reverse movement of the cleaning device.
