This invention relates to a machine for removing dust and vegetable impurities from wool or other fibres.

The principal objects of the invention are to 5 clean the dust and vegetable impurities effectively out of the wool after scouring; to provide an opening effect on the wool but no rolling effect, and to provide a machine which will not break the wool or other fibres and will deliver the wool 1 clean and dust-free.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. 1 is an end view of a wool duster constructed in accordance with this invention;

Fig. 2 is a side view of the same;

Fig. 3 is a plan of a part of a drive, and

Fig. 4 is a side view of the beater showing it in modified form.

Many wool separating machines have been designed for use on wool before scouring to separate burrs, manure, etc. from the wool. This machine is designed for use after scouring to eliminate dust and vegetable fibre and at the same time assist in the opening of the wool.

The machine is supported in a casing I ll which substantially surrounds it. This casing supports air chutes H, shown as two located on one side.

They are provided with dampers l2 to control the draft for the purpose of taking the air out of the machine and carrying with it the dust from the point of contact of the fibre from the beater against the screen. On the top of the casing I0 is a motor I 3 which, in the form shown, drives two fans M which create the draft to remove the air through the chutes II.

The machine is shown as being driven by a motor l5 which directly drives a pulley I6 on a shaft [1 which, by means of a chain l8, drives a corresponding shaft l9. On these two shafts are a series of pairs of rollers 20 arranged along the machine. These shafts can be adjusted by adjusting devices 2| so as to arrange the mechanism to a desired inclination. The rollers 20 support and drive a corresponding number of circular tracks 24 supporting the sifting and separating part of the duster.

This mechanism comprises a cage 22 formed mainly of screen work 23 and constituting a screen. The wool is introduced into the upper end of this screen through a chute 31. This cage is provided with the several circular tracks 26, each track running on two of the rollers 20 and 55 being rotated thereby. These tracks constitute a part of a frame to which are connected longitudinal members 25 and the rotating screen. These longitudinal members 25 are provided at intervals with pins 26 projecting inwardly and forwardly with respect to the direction of rotation. The 5 W001, being introduced into the chute 31 at one end of the cage, as shown in Fig. 2, will be circulated around the cage by being caught up by these pins and then, when the pins come to'vertical position or nearly so, dropping the fibre off directly to the beater hereinafter described. On account of the cage being inclined there is, of course, a progress of the wool from the upper to the lower end where it is discharged into any desired receptacle or on the floor.

Also connected with the motor is a change speed device 30 which, through a belt 3|, drives a pulley 32 on a beater 33. This beater is in the form of a cylinder extending throughout the length of the cage inside it and having its bearings on members 34 carried by the frame l0. These bearings are adjustable by moving either or both ends of the member 34 so that the axis of the beater can be located at different angles to the horizontal and at different angles to the axis of the cage. The beater is provided with longitudinal bars 35, or with pins 36 as shown in Fig. 4, for the purpose of receiving the wool and opening it as it drops from the pins. The beater is located in a position with respect to the axis of the cage so that it will receive the wool from the pins. The main object is to open up the wool and throw it against the screen at a point in line with the chutes, thereby to allow the dust to separate from it at this point especially so that the dust can be drawn out into the hoppers II with the air currents.

In this way dust and vegetable impurities are cleaned from the wool and the wool is opened. The wool fibres are not beaten, as in some classes of machines, enough to break the fibres. The speed of the heater and its inclination can be varied to suit different classes of wool and toenable the operator to obtain the different kinds of results desired. The dust that is not drawn up the intakes H with the air currents is sifted out of the cage by its rotation and falls on the floor. This leaves the wool in a comparatively open and free condition with the dust and vegetable fibres removed. 50

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. In a wool dusting machine, the combination of a rotatable screen cage, a beater located inside said cage at a distance to one side of its axis, means for rotating the cage, means for rotating the beater, said cage being provided with pins inclined to radial lines for taking up the wool and dropping it on the beater for the purpose of opening the wool and releasing dust.

2. In a wool dusting machine, the combination of a rotatable screen cage, an eccentrically placed beater located in said cage at a point at one side of the axis thereof, means for rotating the cage, means for rotating the beater, said cage being provided with inwardly slantingly projecting pins for taking up the wool and dropping it on the beater.

3. In a wool dusting machine, the combination of a rotatable screen cage, located on an inclined axis, provided with pins projecting inwardly tangent to a circle smaller than the diameter of the screen and projecting forwardly in the direction of rotation of the cage, a heater located within the cage at one side of the axis thereof and having an inclined axis, said beater being located in a position to throw stock against the side of the screen and means on the beater for loosening up the wool, said pins being located at such an angle as to drop the wool on the beater as the pins come to substantially vertical position.

4. In a wool dusting machine, the combination of a rotatable screen cage, located on an inclined axis, provided with pins projecting inwardly tangent to a circle smaller than the diameter of the screen and projecting forwardly in the direction of rotation of the cage, a beater located within the cage at one side of the axis thereof and having an inclined axis, means on the beater for loosening up the Wool, said pins being located at such an angle as to drop the wool on the beater as the pins come to substantially vertical position, a chute having an opening at the side of the cage, and means for inducing currents of air from the cage outwardly through said chute to separate the dust and vegetable fibres.

5. In a wool dusting machine, the combination of a rotatable screen cage, located on an adjustably inclined axis and provided with pins projecting inwardly and all tangent to a circle smaller than the screen, a wool inlet at the upper end of said screen, a beater located within the cage and having an adjustably inclined axis, the pins reaching inwardly to a point from which they can drop the wool on the beater, means for rotating the beater at adjustable speeds, a chute opening at the side of the cage, and means for inducing currents of air from the cage outwardly through said chute.
