JOHN B. BRENNER, or ATLANTA, GEORGIA.

SEPARATOR.

Application filed February 11, 1928. Serial No. 258,788.

This invention relates to a separator for removing foreign matter from cotton, the general object of the invention being to pro vide a-vertically arranged casing havmg its 5 upperend connected to the trunk line of the cleaning systemso that the suction 1n the line will create a suction in the casing, the casing havin anairinlet at its lower end, with means or delivering the cotton to. the

casing from the cleaner in such a manner that the foreign matter enters the casing be low the cotton so that the air passmgupwardly through the casing lifts the cotton away from insteadof through th1s foreign matter. v 7

Another object of the invention is to pro vide an adjustable bafile plate in the casing for regulating the. air passage therethrough, the baflle; having a perforated plate 111 its lower end with a catch box back of the plate so that particles of foreign matter, striking the plate, will pass through the perforations therein into the box.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, il-

lustrated in the accompanying drawings and s ecifically pointed out in the appended c aims.

In describing my invention in detail,reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which 2- Figure 1 is an end view showing the improved separator attached to the cleaner device of the cotton cleaning system.

Figure 2 is an elevation.

Figure 3 is a section on line 33 of Figure 2.

Figure 4 is a section on line 44 of Figure 3.

Figure 5 is a section on line 5--5 of Figure 3.

In these views, the numeral 1 indicates the vertically arranged casing which forms the body of the separator, said casing having its front side open and its lower part enlarged. A baffle plate 2 closes the front of the casing, except the lower part thereof, so as to provide an air inlet 3. The upper end of the baflle plate is hinged to the front upper end of the casin as shown at 4, and said plate is adjustab e through means of the lever 5 hinged to the front part of the plate and having notches therein, any one of which is adapted to receive an edge of an angle-shaped cross piece 6 attached to the front edges of the casing. The lower part of the plate is formed with an opening 7 which is covered by a perforated late 8 and a catch box 9 is attached to the rout of the plate 2 and covers the opening. This catch box is provided with a hinged bottom '10 which is normall held closed by the weight on the arm 11. The upper end of the casing is adapted to be connected to the trunk line of the system leading to the condenser so that a suction is created in the casing which draws air through the inlet 3 a part of this trunk line being shown at 14. The dischar chute 12 of the cleaner cylinder, located in the casing 13, is attached to the lower part of the casing, ata point opposite the perforated plateS of the bafile plate 2, and as shownin Figure 1, this chute extends downwardly at an angle from the bottom level of the cylinder;

From the foregoing it will be seen that the cotton and the heavy oreign materials therein are discharged from the cleaner screen or cylinder into the separator casing. The centrifugal force set up in the cleaner causes the heavy materials to be discharged into the casing 1 below the cotton discharged into said casing and the air passing upwardly through the casing 1 lifts the cotton away from this heavy material. The heavy materials also leave the cleaner, traveling at much higher speed than the cotton and resent a smaller proportionate area upon w ich the air can act. Thus there is no danger of this material being mixed with the cotton in the separator casing. The cotton striking the baflle plate 8 will be freed from certain small particles of material which pass into the box 9 and which would otherwise pass upwardly through the separator with the cotton. As soon as the amount of material in the catch box overbalance's the weight on the arm 11, the bottom will drop and thus automatically empty the box. This catch box and bafile plate rids the cotton of fine leaf, etc., which would otherwise pass upwardly with the cotton. called to the fact that the air is drawn from the room into the opening 3 and not through the cleaner casing 13, thereby avoiding a suction in the cleaner cylinder which would interfere with't-he action of the vanes on the cotton.; a

It will, of course, be understood that the heavy materials passing into the separatorcasing from the cleaner screen or cylinder Will drop to the bottom ottheseparator casing from which it may be removed thronglr.

the opening 3 and the materials passing into the catch box throu 'h the baffle )lateare alsoremoved through said opening.

. Itis thought fromthe foregoing-descrip-v tion thatthe advantages and novelleatures .of m invention-will'be readilv a-marent.

Iti's to-be understood that I may make changesin ther construction and in the combinationi and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

' -What I claim is 1. Aiseparator'for a cotton-cleaning tem including a-cleaner and a trunkline-lead ingtothe condensercomprising a verticallly arranged casing;having its upper'end connected with 'the trunk line-and having an air inlet at its bottom; a vertically arranged baffle pIate-in-the casing-,- means for adjusting the-:plate: to regulate the size of the -air pas- I sage through the casing and means for conair inlet at its bottom, a vertically arranged baflle platein the.-casing,;means fOIl adjusting the plate to regulatethe-size of the air passage through the casing, means for con nectingthe lowerpart of the casing with the cleaner of the system at a point below the bottom of the cleaner cylinder, said baffle plate having an opening in its lower end arranged opposite the discharge from the cleaner cylinder a perforated plate covering the opening-- and a catchboX- on the baffle plate for receiving material passingrthrougli the perforations inthe plate.
