FIBER-CLEANING MACHINE.

Specification of Letters Patent.

Patented May it, 1917.

Application filed August 21, 1916. Serial No. 116,025.

will be understood that my invention may be used advantageously for other purposes.

In the opening and cleaning of raw fibrous material, the latter is usually fed into cleaning machines such for example as those known as Willows, the material being tumbled and partially combed due to the rotation of a cylinder within a case, said cylinder generally having teeth thereon which mesh with teeth placed on the interior of the casing in which the cylinder rotates. The fibers are thereby opened or partially opened, and after they have passed through the machine, they are ejected from the casing and in some instances are compelled to pass between pressing or crushing rollers which are so designed as to crush any shives or foreign material so that it will freely drop from the fibers, the fibers passing outwardly either to another machine or to a receptacle for that purpose.

During this pressing or crushing action, some of the fibers also fall with the dirt and shives, which causes waste and loss to the manufacturer. In some instances, some of these fibers may be reclaimed, but since they are mixed with the dirt, it is an expensive process to reclaim these fibers.

One of the objects of my invention is to provide means for reclaiming the fibers such for example as fall during their progress through the pressing or crushing rolls or other means and returning them to the cleaning machine to again be passed through said rollers.

Another object is to so construct my in vention that it will be applicable with practically all forms of cleaning machines and may be connected or built in with the cleaning machine.

A further object is to make my invention of simple construction so that it may be applicable to different types of machines, and

may be manufactured and installed at a reasonably low cost. 7

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which v Figure 1 is an end elevation showing my invention in connection with two Cone Willow cleaning machines and crushing rollers designed to press the fibers as they pass from one machine to the other ma chine.

Fig. 2 is a plan view showing my invention in connection with a series of three cleaning machines of the Cone \Villow the Cone Willows constructed n accordance with my invention, and

Fig. 4 is a section taken on the line aa of Fig. 3.

Referring to the drawings, 1 is a casing which forms a housing for a frusto-conical cylinder 2 which is rotatably mounted in said casing and is provided with teeth 3 which mesh with teeth 4 on longitudinally extending side beams 5 in the casing.

A sieve or screen 6 is supported within the casing and serves to retain the fibers, but permits dirt, which collects due to the dusting of the cleaning action of the cylinder, to fall to the lower portion 7 of the casing where it may be removed from time to time.

The casing 1 has an inlet opening 8 near its narrow end, and an outlet opening 9 at its wide end through which the material after having been dusted, opened, and partially cleaned is ejected.

A frame 10 supports a series of pressing or crushing rolls 11 which are preferably fluted so that they will crush the shives or other foreign material without injuring the fibers. These rollers may be driven in any convenient manner so as torotate and feed the fibers in the direction of the arrow as shown in Fig. 1 of the drawing into the inlet opening of another cleaning machine as shown in Figs. 1 and 2.

A perforated drum 12 is preferably located directly at the innermost end of the outlet opening 9 so as to receive the fibers as they are' ejected by the cylinder 2. This drum acts as a preliminary collector for the fibers, and acts also as a guide for the fibers toward the fluted rolls 11.

Hoppers

13 and 14 are positioned respectively below the rolls 11 and drum 12 and form a receptacle so that the shives or other foreign material which falls during the progress of the fibers between the rolls, will drop therein. Furthermore, any of the fibers which fall will also be collected and retained by said hoppers. The bottoms of the hoppers 13 and 14: are provided with openings to which are attached

suction pipes

15 and 16.

These

pipes

15 and 16 connect with a main pipe 17 which extends upwardly and opens into the casing 1 as shown at 18 in Fig. 3. The large end of the cylinder 2 has a partition 19 which divides the cylinder into two

compartments

20 and 21. The compartment 21 is preferably closed by sheet material 22 which extends entirely around the cylinder, but the compartment 20 is open, the end of said compartment being limited by a spider 23 which acts as a reinforcement and support for the end of the cylinder.

As illustrated, this spider 23 has four arms which respectively assist in supporting the ends of the lags 24 having the pins 3 thereon. This spider 23 is also provided with a central collar 25 through which the main shaft 26 of the cylinder extends.

A fan 27 is positioned within the compartment 20 and as illustrated has four blades 28, each blade being in line with each of the arms of said spider and extend to the partition 19.

The rotation of the cylinder 2 and fan causes a suction of air inwardly through the opening 18 and

pipes

15, 16, and 17, so that any fibers which fall into the

hoppers

13 and 14, are sucked into the compartment 20 and during the rotation of the cylinder, are again ejected outwardly through the opening 9 to pass over the drum 12 and between the rolls 11. The dirt which falls into the hoppers 13 and 141 is heavier than the fibers, and hence remains at the extreme bottom of the hoppers where it may be readily removed.

Any number of machines may be coupled together according to the condition of the fibers to be cleaned.

It will be understood that with my invention, the cylinder acts both as means for opening and cleaning the fibers, while it is within the casing 1, and also acts to operate the fan to suck back into the easing 1, fibers which fail to properly go through the crushing rolls or other cleaning mechanism.

My invention, therefore, is extremely efiicient so that there is practically no waste or loss of fibers by their accidental falling from the crushing rollers.

lVhile I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The combination in fiber cleaning mechanism, of a unitary casing having a movable cleaning member therein, suction producing means in said casing operatively connected to said member and operative in unison therewith, said casing having an outlet through which said member ejects material after it has passed through said casing, a receptacle for receiving material after passing said outlet, and means forming a return passage between said receptacle and said suction producing means whereby material is sucked from said receptacle into the casing and again ejected out of said opening, substantially as described.

2. The combination in fiber cleaning mechanism, of a unitary casing having a rotatable cleaning member therein, said member having a fan operatively connected thereto and mounted in said casing, said fan being rotatable in unison with said member, said casing having an outlet through which said member ejects material after it has passed therethrough, a receptacle for receiving material after passing said outlet, and means forming a return passage between said receptacle and the space within said casing occupied by said fan whereby said fan sucks material from said.receptacle and again ejects it out of said opening, substantially as described.
