E RHEST J. EADDY cme Patented Oct. 13, 1936 UNITED STATES PATENT OFFICE MEANS FOR CLEANING TEXTILE MACHINERY 6 Claims;

This invention relates-to a method and means for cleaning textile machinery such as automatic spoolers, spinning frames and the like, and more especially to a means whereby an induction draft is employed to collect the undesired particles such as dust, lint and fly generated by the process of spooling and spinning yarn and collecting the said particles in a suitable fllter.

It is, therefore, an object of this invention to provide a system of hoppers and ducts for enclosing portions of a textile machine to localize the induced drafts so that the lint and fly on the machine will be drawn through the natural openings of the machine and conducted to a suitable filter where the same is collected.

It is a well known fact that where a direct draft is produced by fans and directed upon textile machinery for cleaning the same, that this draft merely scatters the lint and other particles and contaminates the air in the room in which the machinery is located. Furthermore, the dust, lint and other particles which are removed from the machinery ultimately settle upon the yarn. These lint particles sometimes produce gouts when settled on the yarn which are objectionable because they reduce the quality of the cloth and hinder production by causingbreaking of the yarn in the weaving process.

It is evident that by using an induction draft the air is' not contaminated with these particles but instead, the particles are drawn directly into the ducts. This method produces a more healthful working condition for the operators and also eliminates-the dust and fly from the room which otherwise would materially affect the quality of yarn when it has settled thereon.

It is a further object of this invention to provide a method of cleaning textile machinery which comprises a system of hoppers and ducts connected to a fan for creating an induction draft to clean the textile machinery, and a liltering means disposed on the other side of the fan and having one side thereof connected to the duct which discharges into the same room from whence the air was drawn so that the filtered air is recirculated in the same room. This has a very decided advantage, especially where the temperature or humidity on the outside of the building is different from that on the inside. For example, if the temperature on the inside of the room is 55.2 degrees higher than the temperature on the outside, then for every cubic foot of air drawn from the outside to the inside RElSSUEZl of the room there would be required one B. t. u. to raise this temperature to normal room temperature. It is seen, therefore, that by filtering this air and re-circulating the same, that the temperature of the air is not disturbed ma- 5 terially, therefore, the cost of re-heating this air is negligible. At the same time the humidity of the air in the mill is preserved.

It is a further object of this invention to provide an induction draft for cleaning textile ma- 10 chiriery, means for filtering said air, and means for exhausting said air in the same room and directing the exhaust upona textile machine such as a creel to cause the lint, dust and fiy from the same to be blown to suitable induction open- 15 ings from whence the same is drawn again to the filtering means.

' It is still a further object of this invention to provide means for cleaning textile machinery by an induction draft by enclosing portions of 20 the machinery with battles and with the baffles so arranged as to take advantage of gravity in collecting the fly, lint and dust on adjacent the said machinery and also to locate the baifies so that the centrifugal force and air currents caused 25 by the rotation of said machinery may be utilized for assisting in collecting the trash, fly and lint.

A system as shown and described having a 240 spindle capacity would require about 24,000 cu- 30 bic feet of air per minute to be drawn therethrough in order to produce proper cleaning effects. Therefore, it is seen that if re-circulation and filtering were not employed it would require continuously, approximately 450 B. t. u. 35 per minute, to raise room temperature one degree F. above the outside temperature, while a difference of 30 degrees F. in outside and inside temperatures would require about one pound of coal per minute.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which:-

Figure 1 is a vertical sectional view taken 45 through a portion of a room showingan automatic spooler in elevation with the invention applied thereto;

Figure 1A is a vertical sectional view taken through the other portion of the room showing in elevation the filtering means, the creel and warper;

Figure 2 is a transverse, vertical sectional view taken through the automatic spooler along line 55 53 of the machine.

2-2 in Figure 1 and showing the bobbin supply boxes located on each side thereof;

Figure 3 is a plan view taken along line 3-3 in Figure 1A;

Figure 4 is a sectional plan view taken along line 4--4 in Figure 1;

Figure 5 is a sectional plan view taken along line 5-5 in Figure 1A;

Figure 6 is a transverse, vertical, sectional view taken along line 6-6 in Figure 5;

Figure 7 is a vertical, sectional detail view taken along line 1-1 in Figure 3.

Referring more specifically to the drawings, the numeral l0 denotes a suitable floor of a room having walls II and a ceiling l2. Mounted on floor ID are angles l4 and I5 which form a base upon which is mounted end frames or Samsons l3 and i1 and intermediate frames or Samsons I8 and I9, 20 and 2| of an automatic spooler.

An automatic spooler is divided into a plurality of sections such as shown in the drawings between Samsons I8 and I9 or between Samsons 20 and 2|. Extending from the opposite sides of each Samson are suitable brackets 25 and 26 having mounted on the ends thereof

bobbin supply boxes

21 and 28, these boxes being shown in Figure 2, but omitted in Figure 1 in order to more clearly disclose the invention.

Secured to each side of the intermediate portions of the Samsons I8 and 2| are

longitudinal channels

29 and 30 which serve as struts for rigidly tying the Samsons together. Rotatably mounted in the upper portion of the Samsons are cylinders 3| and 32 which rotate in the direction designated by the arrows and cause the cheeses or packages of

yarn

33 and 34 to likewise rotate and draw the yarn from the bobbins 35 and 36 upwardly through combs 31 and 38 respectively, to cause the same to be wound onto the packages. A suitable trackway 39 is disposed on the upper side of Samsons ii to 2i and the end frames l6 and [1, upon which a carriage (not shown) is adapted to travel and cause empty bobbins to be replaced by a full bobbin of yarn in the spooler.

Also disposed between each of the frames l3 to 2| is a cover plate 40 and a suspended baflie 4| pivoted as at 42. On opposite sides of each Samson are upper brackets and lower brackets 46 'upon which a conveyor belt 41 is adapted to travel for receiving the empty bobbins after the same have been dofled from the bobbin holders 43 and convey the bobbins to a suitable container (not shown) at the end of the spooler.

The parts thus far described are conventional in conventional spoolers but it is deemed necessary to disclose this much of theold structure in order to more clearly describe the invention.

In order to use an induced draft to clean the machinery as disclosed in the drawings, it is necessary to install suitable baflles in various portions of the machine so that the draft may be directed through the natural openings of the machine to remove the dust, lint and fly therefrom and also to prevent the same from collecting thereon. Suitable baflles 50 and 5| have been secured between each of the Samsons or in each section of the spooler, to longitudinal struts 52 and These bailies 50 and 5| converge downwardly, forming an opening 54 through which the downward current of air passes together with the dust, lint and fly from the upper portions of the machine and particularly that dust and fly which is created by cylinders 3| and 32 and the

cheese rolls

33 and 34.

While cylinders 3i and 32 do not, in themselves, create the induction draft, it is seen that since the upper side of the rolls rotate inwardly that the induction draft created by the fan, which will be presently described, will be materially assisted in collecting the fiy and lint and transferring it downwardly through the opening 54.

Secured to

longitudinal channels

29 and 30 are conventional baflles 56 and 51 which extend downwardly and have the lower edges thereof secured to the sides of the frames l6a to 2 la. These baffies will cause the draft which passes downwardly through the

bobbin boxes

58 and 59 to thoroughly cleanse the interior portions of these boxes as well as the exterior of bobbins 35 and 36. A current will also be drawn downwardly through the openings which exist between the lower edges of baflle plates and 51 and the conveyor belt 41.

Bafile plates GI and 62 are secured to the upper edges of hoppers 60, said baflie plates having the upper edges thereof abutting the inside edges of

bobbin supply boxes

21 and 28. By placing theupper edges of these plates in the position shown in Figure 2, it is seen that the dust and lint from the top of the supply boxes will also be drawn downwardly into the hopper 60. The structure described inFigure 2 is typical of the structure in each of the sections of the spooler. In other words, the structure between Samsons 2Uand 2| and the other Samsons and'frames of the machine, not shown, is identical to the structure between Samsons l8 and I9 and frames l3a and Mia;

therefore,like reference characters will be given like parts and another description will not be 55 made for the other sections.

Connected to the lower end of hoppers are vertically disposed pipes 65 which lead' into a horizontally disposed pipe 66, said pipe. 66 increasing in size as it progresses to the right in' Figure 1, since this pipe serves as a trunk line. v

Pipe 66 leads to the intake opening of a suitable fan 61 which fan is connected to the lower side of the floor Ill. The pipe 66 is held in position by suitable means such as hangers 58 sus pended from the lower side of floor l0.

Fan 31 exhausts into a suitable duct or pipe 10 which extends upwardly through the floor l0 and leads into a filter 1| which is suspended from.

the ceiling l2. The filter 1| is lined with a suitable filtering material 12 such as textile fabric or wire fabric and has a suitable. hinged door 13 in the lower side thereof pivoted as at '14 and having latch 15. This door may be opened when it is desired to remove the accumulated fly, dust and lint caught by the filtering material 12. The filter II has baflie plates 16 on the front edge thereof for directing the exhaust current of air downwardly onto the creeling apparatus which will be presently described.

A shield 11 encircles the filter 1| and causes the currents of air which pass through the filter to be directed downwardly in the direction of arrows as shown in Figures 1A and 6.

The exhaust from filter 1| is directed down rear of the machine. The creels and! have conventional fans 33 and 84 for blowing the par ticles from the strands of yarn as it is drawn from the creel to the warper thereby preventing it from collecting on the yarn.

After the particles are blown onto the floor, the exhaust air from the filter 1| blows these 2,057,189 particles rearwardly of the creel frames to openings and 89 where it is drawn by the suction produced by the fan 67 downwardly through the floor into

pipes

81, 88, 89, 99 and back into pipe 86, whereit is pulled through the fan 51 and forced into the filter H. Hangers 9| are used to suspend

pipes

89 and 99 from the lower side of the floor I9.

In order to cause these particles to be gathered at the

openings

85 and 88, a curb 92 is provided which, in the present instance in Figure 3, resembles a rough w in its plan view. This curb (Figure 1A) extends a slight distance above the fioor level in order to properly direct these particles to the openings. The

creels

89 and 8| have a plurality of packages of yarn 93 thereon which are wound onto a warp beam 95 of warper 96. The strands leading from the packages 93 pass through comb 91, over roller 98 and then onto the warp beam. This warp beam is rotatably mounted in arms 99 and I99, which arms support guard rail I9I.

It is well known in the art of creeling and warping that movement produced by the rotation of warp beam 95 will cause all of the strands from the packages of yarn 93 to move rapidly toward the warp beam at approximately 999 yards per minute. -This swift movement of the ends will cause an induced draft to be set up which will be overcome by the exhaust draft from the filtering apparatus 'iI, thereby causing the fly and lint which falls upon the fioor to be directed rearwardly to the openings 85 and 86 instead of toward the warper 96.

It is also desirable to cleanse the warp beam 95 during the operation of the creeling apparatus; therefore, a slotted pipe I95 has been mounted in parallel relation to the warp beam 95 and this pipe'is located with its slot I96 adjacent the surface of the warp beam. This slot I96 extends approximately the length of the warp beam and collects the lint particles from the surface of the beam by virtue of the induced draft set up by the fan 61. The pipe I95 is U-shaped and has each end thereof pivotally connected as at I98 and I99 to vertically disposed ducts I I9 and III respectively. These ducts lead downwardly through the floor I9 and are connected to vertically disposed duct H2, said duct H2 having its lower end connected to pipe 99.

It is thus seen that the lint, fly, dust and other foreign particles which are created by the rotation of the warp beam will be collected and transferred downwardly through the pipes II9, III, 2 and 99 back into the pipe 66. From this pipe, the dust, lint and other foreign particles will be drawn through fan 61 and forced upwardly through pipe 19 into filter 'II where the air is filtered and the exhaust is used to blow the trash from the creel frames 89 and 8| into

suction openings

85 and 89. I

By filtering the air andusing the same over and over again in the mill, the temperature and humidity of the air is not materially affected; therefore, the air can be re-circulated through the room without the necessity of drawing in outside air which is very often of diilerent temperature and humidity from that of the room.

To draw in outside air would necessitate additional expense. By using an induction draft for cleaning the machinery,.the particles of dust, lint and fly; are collected from the room and the air is purified or conditioned. This creates a decidedly more healthful working condition for the employees as the air is purer and more free from lint and dust than it would be if a direct cleaning machine were used, that is, cleaning machinery which does not collect any dust or lint from the machine but merely removes the lint from the machine by exposing the same to a direct blast of air.

In the drawings and specification there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being set forth in the appended claims.
