(CI. 19—75) This invention relates to new and useful im The invention will be more readily understood provements in separators. from a reading of the following speci?cation and One object of the invention is to provide an by reference to the accompanying drawings, in improved cotton separator which will efficiently which an example of the invention is shown, and 5 drop the cotton from the airstream which draws wherein: the cotton from the wagon, or other source. An important object of the invention is to pro vide an improved cotton separator which is so constructed that a continuous suction or pull may 10 ‘be effected, which makes for more e?icient feed ing of the cotton into the separator. An important object of the invention is to‘ pro vide an improved cotton separator wherein a por tion of the separating screen ‘extends over the in let, with means for wiping the entire surface of the screen, whereby upon the introduction of the cotton into the separator, the air is immediately separated 20 therefrom and passes upwardly Figure 3 is a transverse, vertical sectional view 10 of the same, Figure 4 is an enlarged, partial vertical, sec tional View of the vacuum wheel, Figure 5 is a front elevation of the same, and having a portion of the casing broken away, and Figure 6 is an enlarged partial perspective‘ of the paddle wheel. In the drawings, the numeral iii designates an air-tight casing or housing which is preferably Still another object of the invention is to pro vide a cotton sepaartor' having an open reel constructed of sheet metal, or other suitable ma terial. An enlarged air conduit ii is connected to the lower end of the rear wall of the housing which permits the cotton to quickly fall down 25 "wardly within said separatorby gravity. A further object of the invention is to provide an improved separator wherein the incoming cotton is dropped into a deadair space, and means for removing the cotton from‘ this space, 30 whereby the cotton emitting from the separator is entirely free of air. Still another object of the invention is to pro vide a separator having a comparatively coarse screen therein, with means for constantly keep 35 ‘mg the entire surface of said . screen clean, whereby the air may readily pass therethrough and also whereby particles of dirt, or other ex traneous matter may also be separated from the cotton. A particular object of the invention is to pro vide an improved cotton separator having a flared inlet, whereby choking of said inlet is obviated and also whereby the incoming cotton may ex pand to open up said cotton and separate the 45 removed, through said screen. therein, whereby substantially no obstruction to the cotton introduced ‘into the separator is had, 40 Figure l is a perspective View of a separator, constructed in accordance with the invention, Figure 2 is a similar view, having an end wall docks thereof, which greatly improves the condi tion of the same. A still further object of the invention is to provide an improved vacuum paddle wheel for a cotton separator which is simple and sturdy in 50 ‘construction, and which is arranged so that its ?exible blades may be readily replaced without removing the wheel from the separator. A construction designed to carry out the in vention will be hereinafter described, together 55,.with other features of the invention. to.0: and communicates with the interior thereof. The conduit is preferably disposed at an angle so that a free passage of air from the housing into said conduit may be had. A suitable cotton suc tion fan (not shown) is located in the other end of the conduit ii and thus, it will be seen that said fan will draw an unobstructed stream of air from the housing into the conduit. The front wall of the casing or housing extends forwardly‘and converges toward the central por— tion of said housing, whereby a reduced cotton inlet it is provided at the extreme forward end of the housing. It is pointed out that this inlet 30 ‘r extends transversely throughout the length of the housing.’ A suitable transition M is connected with the inlet i3, and this transition communi cates with a conductor (not shown) leading to the wagon or other source of cotton supply. It is obvious that when the suction means at the end of the conduit Ii is operating, cotton is drawn through the transition ill, inlet i3 and into the housing Ill. The suction means exerts an un diminished, contiuous pull on the cotton within the transition ill due to the location of the inlet i3 centrally of the housing and also due to the particular disposition of the conduit H, whereby an even flow of cotton into the housing is had. The lower end of the housing is provided with a transverse opening it which extends the full length thereof and a suitable discharge spout Iii which has a general circular shape in cross-sec tion, is connected to the, discharge opening. A Vacuum paddle wheel ll is rotatably mounted 55.. 2,114,553 2 within the discharge spout and is so constructed as to prevent the escape of air through the dis charge spout while permitting the discharge of cotton from the housing iii. The details of the paddle wheel will be hereinafter described. A suitable outlet conductor i3 is connected to the lower end of the spout iii. For preventing the cotton which is drawn into the housing iii through the inlet 13 from escaping through the air conduit l i, and also for directing such cotton to the discharge spout 55, a curved metal sheet I8 is located within the housing. This sheet is suitably secured to supporting mem bers 19 which are fastened to the rear and upper 15 wall of the housing. The supporting members it not only hold the sheet 18 in position within the housing but also serve to space said sheet from the rear wall thereof, whereby an air space or passage 2% is provided between said sheet and the As is clearly shown in Figure 3, the sheet 18 extends from the upper end of the inclined front wall of the housing and curves rearwardly and downwardly in front of the open end of the air conduit Ii. The sheet is 25 provided with a plurality of perforations or open ings 2! which extend from its extreme upper end 20 rear wall of the housing. down to a point at some distance from the lower end thereof. In other words, the perforations terminate short of the lower edge of the sheet, 30 whereby a solid baffle 22 is formed by this unper forated lower end of the sheet. As is clearly shown in Figure 2, the solid portion or ba?ie 22 of the sheet extends transversely the entire length of said sheet and is located just above the dis 35 charge opening or outlet [5 of the housing. As cotton is drawn into the housing through the transition 14 and inlet i3 by the suction created in the conduit II, it will be seen that said cotton will ?rst strike the ?ared front wall 40 of said housing. The wide angle formed by the converging front wall provides ample space for expansion of the incoming cotton and immediate ly a portion of this incoming cotton will drop downwardly through the discharge opening 15 45 in the housing. Also, this increased expansion space prevents the cotton from crowding against the top of the housing and thereby, prevents any choking effect at the inlet. The cotton which does not drop immediately upon its introduction 50 into the housing In will, of course, be drawn with the air stream against the perforated sheet iii and will follow the contour of said sheet until it ?nally passes out to the opening 55 into the dis charge spout !8. The air upon entering the inlet 55 i3 will, of course, immediately rise and pass through the perforations in the forward end of the sheet H! which overlies a portion of the ?ared forward end of the housing. It is noted that the perforations 2i of the sheet 60 are comparatively large, whereby dirt and other extraneous matter is drawn through the perfora tions. Due to the ba?ie 22 at the lower end of the sheet, it is obvious that the air must follow the contour of the housing since it cannot pass di 65 rectly in a straight line from the inlet i3 to the conduit I 1. By directing the air in this manner, it is obvious that a circulation is set up within the housing. For wiping the perforated sheet 88 so as to 70 keep the perforations 2! open, whereby the pas sage of air therethrough is not interfered with, a rotatable wheel 23 is located Within the housing iii. The reel includes a plurality of spiders 24 mounted on a transverse shaft 25 which has its. 75 ends suitably supported in the end walls of the housing. The shaft is preferably in horizontal alignment with the inlet opening l3. Each spider is provided with a plurality of radially extending arms 26 which have transverse flexible wipers 21 suitably secured thereto. The curvature of the perforated sheet ii! at its upper end is substan tially the same as the radius of the arms of the spiders, whereby when the reel 23 is rotated the flexible wipers 2'5 will engage the surface of the sheet to clean the same. It is noted that the con 10 struction of the reel in this manner provides an open structure, whereby the passage of air through the housing is not interfered with by the rotation of the reel. This eliminates an intermit tent pulsating eifect on the suction because the 15 usual solid paddle wheel is replaced by the open reel 23. Also, the open structure does not inter fere with the falling cotton within the housing. It is further pointed out that the curvature of the perforated sheet i8 is such that the entire portion 20 of said sheet is wiped or cleaned by the reel and thus, since the screen is kept clean, the suction is stronger because there is less tendency of the screen to clog. From the above, it will be seen that the cotton 25 is drawn into the housing through the inlet l3 and immediately enters the ?ared front portion of said housing wherein it is permitted to expand. Due to the inlet being located centrally of the ?ared front portion, it is obvious that the air will 30 immediately rise in the housing while the cotton will drop down. The rising air will, of course, pass through the perforated screen and then fol low the curvature of the housing, passing out wardly through the conduit I i. All dust and dirt 35 of a ?ne nature will pass with the air through the perforations in the sheet and will thus be separated from. the cotton. The cotton upon en tering will, of course, immediately expand and then fall into the discharge spout It. The ex 40 pansion of the cotton will cause the cotton to be separated whereby any solid wads which may have been formed in the cotton previous to its inlet, are broken up. Thus, the cotton is opened up and the locks separated to a great extent, 45 whereby the cotton is in a good condition to be handled through the distributor or cleaning ma chinery (not shown) to which it is carried after it leaves the housing. The open reel not only offers no obstruction to the falling cotton but also 50 permits air to freely ?ow therethrough and thus does. not interrupt the suction necessary for drawing the cotton into the housing. As the air is separated from the cotton, said cotton will drop downwardly through the outlet 55 opening 55 in the bottom. of the housing and will fall into the discharge spout 18. Upon entering the spout N3, the paddle wheel i'i therein will carry the cotton downwardly and discharge it into the outlet conductor 58. The paddle wheel 60 I’! may be of any desired construction but it is preferably made of a plurality of supporting spi ders 30 which are secured on a transverse shaft 3| extending the full length of the discharge spout iii. The spiders are provided with radial 65 arms 3! and the space between the spiders is closed by a transverse substantially V-shaped partition 32 which is located between the arms of the spider (Figure 6). These partitions are suitably bolted in place by retaining members 33 which follow the contour of said partitions and the spider arms. As is clearly shown in Figure 6, the outer edges of the partitions 32 extend be yond the end of the arms 3i of the spiders and ?exible wipers 3A are secured or clamped between 75 2,114,552“. these .extended outer edges ‘of the partitions. It is obvious that - as the paddlewheel thus formed» rotates within‘. the dischargespout ltthe ?exible wipers.34:willcontactitheinner surface of the . discharge spout and will. thus prevent the .escape cleaning machinery. A..hinged panel 10' may be, providedinthe front wall'of the housing l0 so that 1 the interiorof the housingmay be. readilyi.a'c—i cessible.- It is .noted that the. wiper Zluon-the reel as well as .thewiper on-thepaddle-wheel: 5 Q1. ll zmaybe readily replaced without removingthe of. any air through‘ said spout.

The extremeiouter end of this shaft carries anv enlarged‘ gear 35 and this gear is con nected through a chain 36 with a small gear 31 which ismounted on‘ the extended end of the 25 .shaftw3l sof the .paddle wheel. A motor, or ‘any other suitable ‘means, maybe connected to either‘ oneof the shafts to. rotate thesame, but I have shown. a drive wheel ‘38nmounted on the paddle wheel shaft 3!. A belt is arranged to. pass over 3 0 .this drive wheel to impart rotation to said shaft. It isclear ‘that when thepaddle wheel I1 is ro tated at a given speed, the reel 23 will be rotated at a much slower speed due to the connection be tween the small and large gears 31 and 35 respec tively, by the chain 36. The operation of the device is obvious. The suction means (not shown) at the end of the con duit II will draw the cotton from the transition l4 into the housing In through the reduced inlet Upon entering the housing the cotton is permitted to expand due to the wide angle of the front portion of the housing. The air will immediately tend to rise within said housing while the cotton will drop toward the discharge 4 5 spout IS. The open reel 23 will not interfere with the falling cotton or with the air stream 4 0 I3. whereby an undiminished continuous pull on the cotton is had. The air will, of course, escape through the perforations in the sheet I8 and will carry any ?ne dust or dirt therewith. As the cotton falls toward the discharge opening l5 it will be seen that it will fall opposite the ba?‘le 22 formed by the unperforated section of the sheet 18. This ba?le causes the air to pass upwardly therearound into the conduit H and thus creates a dead air space at a point just above the dis— charge opening W. The revolving vacuum pad dle wheel ll removes the cotton out of the air below the sheet. The structure of the paddle 60 wheel prevents any escape of air through the dis charge and thus only cotton alone is carried to» the outlet conductor l8. Due to the wide in ternal angle adjacent the inlet l3, it is practically impossible to feed sufficient cotton through a 6 5 standard telescope to choke the separator down by overfeeding the suction. It is obvious that the vacuum feeder can be speeded up to suit the particular installation. It is again noted that this type of cleaner is a great improvement in the 70 preparation of the cotton for ginning. Instead of being dropped in solid wads as tramped in the cot ton wagon, or other source of supply, the cotton is opened up and the locks separated to a much’ greater expanse, so that the cotton is in good con 5 dition to be handled through the distributor or discharge in theb-ott-om cfr-the,housingwforthe cotton therein. 2.
