6 Claims.

braced by longitudinal tie rods and spokes or drumis mounted in a housing which directs the air stream coming from the linter brush and carrying the lint and as the air passes through the screen like drum the major portion of the lint is deposited upon the drum as it rotates and is collected on the roller at the rear side of the condenser.

rotate in a novel manner without the use of spokes, or longitudinal or radial braces, leaving the interior of the drum entirely open and thus making it possible to provide fixed shields within the, drum to direct the air current into a flared conduit, also located in the drum with the ends of the drum sealed off so that the air may be confined and directed through a single outlet flue from which it may be conveyed away together with the lintand the dirt contained therein to the end that the lint and dirt will not be permitted to dissipate into the gin room.

It is another object of the invention to provide a novel type of condenser which may be applied to a single gin or linter so that the lint being delivered from the gin may be condensed and the air laden with dust and foreign matter may be confined and entrapped and conveyed to a point outside of the room and the dust nuisance withinthe room thus abated.

The type of condenser herein described is specially adapted for use with a single linter thus conducing to a thinner bat of lint being deposited on the drum and facilitating the disposition of 50 the dust generated by the linter; furthermore the lint produced by each linter can be more uniformly regulated for each linter is provided with its one condenser.

Since the linter brush generating the air cur- 5 rent works against back pressure caused by the air having to pass through a bat of lint on the condenser, if a single condenser is employed with ing from the condenser. 0

By the use of a condenser of the type described with each linter it has been found in practice With the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrange- 20 Figure 1 shows an end view of the condenser.

ing flanges la-4a, note particularly Fig. 3, and the foraminated drum or screen 3 lies within the boundary of said flanges. Thus, any lint collecting on the drum is out of the way of the internal gear teeth and the flanges function not only to reinforce the ring but also insure against lint passing over the ends of the drum to said teeth.

A transverse shaft l0 extends through lower portion of the drum and is mounted in the inside bearings II, II fastened to the rear legs of the end supports I. This shaft gears l2 fixed and drive the ring gears 5 thus rotating the drum on its supporting rollers 6. The outer end of the shaft ID has a sprocket wheel 13 fixed thereon over which a driving sprocket chain may operate to rotate the shaft H3. Other driving means for the drum than that specifically hereinabove described may be employed.

Above the drum there is a compression roller l4, preferably formed of wood, which extends approximately from end to end of the drum. This roller is fixed on a central shaft l5 whose ends extend beyond the roller and are located in the vertical U-shaped bearings i6, 6, at the upper ends of the end castings 9. The ends of the roller i4 have the metal ferrules Ma, Ma having extended circular flanges I l-b, Mb which roll on the tracks 4.

There are the roller supporting arms I1, I'I, whose upper ends are pivoted to the upper ends of the end castings 9 and the lower ends of these arms have the upwardly open bearings l8, 18, to receive the ends of the shaft I9 on which the bat receiving roller 20 is mounted. This roller cooperates with the drum 3 and is provided to receive the compressed bat of lint 2i. The bat rolls about said roller 20 as indicated in Figures 1 and 2, the arm 11 permitting the roller 20 to move outwardly from the drum as the roll enlarges. The roll of lint, when it reaches the desired size, may be removed and another roller 20 replaced for the removed one.

As the lint leaves the linter, it is carried by the air current through the lint flue 22 to the drum. This flue is enlarged adjacent the forward side of the condenser which is of a width approximately equal to the length of the condenser and which extends upwardly to the compression roller [4. It confines the lint to the forward or exposed area of the drum 3. Within the drum there is fixed the housing 24, preferably formed of sheet metal and of a length substantially equal to the length of the drum. This housing is of a frusto-conical form having its small end open and arranged close to the drum at one end with its larger, or discharge, end arranged at the lowest point of the drum and being there connected to the outlet flue 25. 24 is provided with a longitudinal slot 26 approximately parallel with the axis of the housing and arranged opposite the lower portion of the There is a vertical partition 21 of a length of the drum 3 and extending side wall of the drum, opposite the roller Hi, to the upper margin of the slot 26. There is a skirt, or platform, 28, also preferably formed of sheet metal and extending from the lower margin of the slot 26 forwardly to the inner wall of the drum and in approximate alignment with the bottom of the hood 23, the drum, as it rotates, thus moving betweentheadjacent confronting margins of the bottom of said hood and said skirt or apron.

in has the spur thereon which are in mesh with forming the hood 23 The portions of the ends of the drum between the partition 21 and the hood 23 are closed by the end plates 29, 29, suitably secured to the framework.

The air from the linter and carrying the lint cotton enters across the face of screen or drum uniformly distributed and deposits the lint on the drum passing onwardly through the slot 28 into the housing 24 and the air laden with dust, and a certain amount of fine lint, passes on toward the large or outlet end of the housing and into the outlet flue 25. Since the housing gradually enlarges toward its dicharge end more capacity is provided for the constantly increasing amount of air to be handled and the dust carried into the confined area in front of the partition 21 will gradually move downwardly until it is caught up by the air current from the conventional suction fan connected with the outlet flue 25 and will becarried away thus preventing collection of dust or other foreign matter in the condenser. housing 24 declines toward its outlet end to facilitate the exit of the dust and foreign matter.

The ends of the housing 24 as well as the partition 21 and skirt 28 are suitably anchored to the-end castings 9 and to the end cross bars 2 to provide a rugged structure.

The drum rotates in the direction indicated by arrow in Figure 2. The lint will be deposited, as above stated, in the form of a tion of the drum inclosed by the bat will pass underneath the roller l4 and be compressed thereby and will move on to the roller 20 around which it will be rolled until the roll has reached the required size. As the bat passes the roller l4, the air under compression from the linter brush as well as the air suction from the fan will be out off from it.

The bat will thus be released from the drum and will be free to accumulate on the roller 20.

A substantially closed conduit will thus be formed from the linter, through the condenser, to the point of discharge, thus preventing the escape of dust and free lint into the linter room.

By reason of the construction a completely inclosed condenser may be connected with each linter so that the linter may operate as heretofore but making it possible to collect all the air generated by the linter brush after this air has deposited its lint on the drum or screen and only the air coming from the brush is required to be handled.

The lint passing through the screen into the housing and out through the lint flue 25 may be collected and recovered.

It may be noted that the confined area defined by the partition 21, the housing 24 and the skirt 28 is such that any dust collecting therein will be aided by gravity as well as by air suction in its movement toward the discharge, that is to say, the skirt declines toward the slot 26 and the axis of the housing 24 declines toward the point of exit and as is obvious the partition 21, is in an approximately vertical plane to the end that there is no point in the confined area from which any material will have to be lifted against the force of gravity. 7

The drawings and description disclose what is now considered to be a preferred form of the invention byway of illustration only, while the broad principle of the invention will be defined by the appended claims. I
