l Claims. (Cl. 239-547) l This -invention relates to the art of lremoving bers from textile machines and is particularly concerned with a new tube or boot having outlets through each of' which aircan be directed in any one of many different directions.

Heretofore, apparatus for removing lint from textile,

stream oi air could escape and flow into contact withr parts ofthe machine and dislodge lint therefrom. The tubes or boots were positioned to move in fairly close proximity to the sides of the machines, for example close tothe pig'tails of a spinning machine, and since these'tubes or boots could move to a limited extent toward the side of the machine, therewas danger that part `of the machine might enter some of these holes and tear the tube or even dislodge it from the overhead supporting casing. Moreover, the holes formed in the side of the tube afforded no means for varying at will the direction of the streamo'f air flowing therethrough.

' The present invention aims` to provide ka boot/having air outlet. lnozzles which are not susceptible` to being snagged by parts ofthe machine and which may be readily adjusted to direct the stream of air issuing therethrough into any one of a plurality of directions. The present invention-,achieves these objects by providing a nozzle having a ange near one end thereof in a plane at an acute angle to the center line of the nozzle, and means toipretainI against the flange the part of the boot surroundingthe opening through which the nozzle projects.

The present invention will be better understood by those skilled-in the art from the following specification and the drawing accompanying it in which:Y

Figure l is a fragmentary perspective view of apparatus with which the present invention may be employed; Y

Figure 2 is a fragmentary perspective vieweofa preferred form of the present invention;

Figure 3 is a cross-sectional view taken on line 2--2 of Figure l;

Figure 4 is an enlarged fragmentary sectional view of a portion of Figure 2 showing the'relative position of the nozzle, a wall of the boot and the means to retain that wall in the groove of the nozzle, und

Figure 5 is a fragmentary enlarged sectional view taken and this carriage has mounted thereon a fan 4 to be rotated by a motor (not shown) and a casing or housing 5 surrounding the fan and having opposite outwardly and downwardly extending conduits 6. It will be understood Frice Y that air is drawn through the upper side of casing 4Y and into the interior of fan 4 whence it is propelled o'utwardly and ydownthrough conduits 6.

In Figure 2 is shown fragmentarily part of one of the two tubes or boots which, attheir upper ends, are to surround and be attached to conduits 6. Since the boots are constructed similarly, a description of one willsuflice for both. s

` Tube or boot 10 as shown is preferably rectangular in cross section and has Vfour walls 11. VAny other cross sectionalY shape which is suitable may be employed as those skilled in the artwill understand,H and while walls 11 are preferably constructed of reinforced fabric impregnated with rubber Vto prevent ow of air therethrough, it will be understood that these walls may be composed of other suitable material which will retain and directV the vstream. of air downwardly through the tube. Also slats 12 may be located in pockets 13- in the leading and trailingsides of the tube 1li to permit bending ofthe.

tube in directions parallel to the tube travel but will resist'bendiug in directions normal tothe machine to be cleanech, f

kThe yside wall 11 of the tube which is opposed to the machine from which line is to be removed is provided with a plurality of.discshaped holes Ithrough each- 'of whichv anozzle 15. projects. As many nozzles may be used as are needed or desired to direct airrstreams against the predetermined places on the machine to be cleaned. 'lhe nozzle 15 comprises -atube 16 having two annular ribs 1'7 and 18 projecting therefrom adjacent to one end thereof and disposed at an acute angle to the longitudinal into the tube as far beyond the rib 1S as is desired. The

nozzle may be cut away within the tubes as indicated at 19 -to serve as a scoop tor intercept part of the air stream and direct it through the nozzle. When the nozzle is to s be assembled with the side 11 of the tube, the nozzle is Y i Vpushed through the hole in Wall 11 so that rib 18 is v` within the tube and bearsagainst the inner surface of wall 11 around the hole therethrough with that wall projecting into groove 20.- The nozzle and wall 11 are maintained Yin such assembled position by two O- rings 21 and 22 which lie in groove 20. O-ring 21 is preferably slightly smaller in inside diameter than the diameter of the groove VZtl and O-ring22 has an inside diameter pref# erablyqslightlysmaller than the outside diameter of ring 21. Thus,rwhen.these rings Yare in assembled position as shown in Figure 4, both rings are in tension, and pressinwardly in the groove and are deformed laterallyso as to` press against wall 11 and retainA the nozzle'in its assembled position. n Y, j

'Itwill be understood that while Figure 2 shows the nozzle 15 in position to direct a stream of air downwardly at an acute angle to the center line of the tube, the position of the nozzle may be readily changed by simply removing rings Z1 and 22, rotating the nozzle 15 relative to the wall 11 to the desired extent and in the desired direction, and then replacing the rings 21 and 22 in the groove. Thus, when the plurality of nozzles 15 are employed in one tube, air may be directed at an kacute angle to the longitudinal axis of the boot and in almost any position throughout a complete circle although the amount of air flowing through a nozzle varies somewhat depending on the position of the tubular part 16 of the nozzle. For example, if the nozzle points upwardly, less air mayV be expected to flow through it than when the nozzle points downwardly because the direction of the air flow in the boot is downwardly and hence more of it would tendr to enter and flow through the nozzle when it extends in the same general direction.

Since the nozzles are adjustable, they may be so positioned, where there is danger that they might be snagged by a part of the machine, that such snagging wouldbe impossible. For example, a nozzle positioned at the level of the pigtails could be adjusted to blow the air backwardly and thus present the sloping surface of tube 16 to the pigtails which would not snag the nozzle but would slide over that inclined surface. Furthermore, the use of this invention makes it possible to remove lint from substantially all parts of a machine because the several nozzles or some of them may be re-adjusted from time to time to direct the air streams against other parts of the machine not through being contacted by the air streams. In addition to these advantages, the present invention makes it possible readily and easily to assemble, disassemble and adjust one or more of the nozzles in the boot as may be desired.

Having thus described this invention in such full, clear, concise and exact terms as to enable any person skilled in the art to which it pertains to make and use the same, and having set forth the best mode contemplated of carrying out this invention, we state that the subject matter which We regard as being our invention is particularly pointed out and distinctly claimed in what is claimed, it being understood that equivalents or modications of, or substitutions for, partsV of the above specifically described embodiment of the invention may be made without departing from the scope of the invention as set forth in what is claimed.
