7 Claims.

This invention relates to the art of reclaiming used journal box waste as illustrated by the U. S. Letters Patent No. 2,090,260, issued August 17, 1937, to applicant and others on a Process of reconditioning used waste. In any process of reclaiming used journal box waste, it is a common procedure to first initially loosen up the waste in hot oil, remove the wash oil by some compressing action such as by centrifugal action, a press, or the like, and then re-oil the waste with usable lubricating oil. During the reconditioning or reclaiming of the used waste, it becomes necessary at some step to loosen and fluff the waste so as to restore it to a resilient condition as opposed to the matted compressed condition it has reached when removed from the journal box.

It is a primary object of the present invention to provide structural means that will shake out and fiulf the waste in a very effective manner without tumbling it and rolling it over and over, following an initial soaking or washing of the waste with hot oil. When the waste leaves the centrifuge or the press, the waste is quite compacted and it is the purpose of this invention to eliminate this compacted condition.

A further primary object of the invention is to provide such structural means as above indicated which will permit a continuous operation without intermittent stops and which will not only loosen the waste from its compacted condition but will also tend to shake out foreign matter as well as undesired short ends if such be present.

A further important object of the invention is -to provide an exceedingly simple mechanism which will operate without requiring air blasts or any mechanical means tending to roll the waste, but instead operate much as a pitch fork is em: ployed in shaking loose baled straw and the like on the farm.

These and many other objects and advantages of the invention will become apparent to those versed in the art in the following description of one particular form of the invention as illustrated in the accompanying drawings, in which Fig. 1 is a side elevation of the central fragmentary part of the washing mechanism, as illustrated more fully in the U. S. Patent No. 2,090,260, to which the present invention is applied;

' lines tothe dash lines i action Like characters of reference indicate like parts I throughout the several views in the drawings.

It is to be understood'that while reference is made to the process of reconditioning used waste described in the U. S. Letters Patent No. 2,090,260, such process and the apparatus shown in that patent are referred to simply as one particular process to which the present invention may be adapted. In that process, there is a conveyer III which is continuously pulling waste up-an i clined platform I I from a wash tank (not shown). From the discharge end of the platform II, the waste drops into the hopper I2 on the upper side of a press I3 corresponding in detail to the press shown in said Patent No. 2,090,260, the details of which press do not enter into the presentinvention. The press is referred to simply as one means of compressing the soaked or washed waste to remove the excess or principally all of the rinse or wash oil from the waste, the waste being discharged from the press I3 in a very compacted condition with only a firm coating of oil remaining'on the waste fibers. As indicated in Fig. 3, two of these presses I3 one beside the other.

The discharging waste from these presses I3 is caught upon a series of-fingers I4, herein shown as being directed away from the underside of the discharge openings of the presses I3 in substan-- tially horizontal directions and in a common plane. Rear ends of these fingers I 4, are secured in any suitable manner, such as by welding to a transverse bar I5 that is carried by the upwardly extending arms I6 and I7.

The upper ends of these arms are carried by crank pins I8 and I9 respectively projecting in the present forms'from discs 20 and 2| rigidly mounted on a transverse shaftVZZ above the presses I3. The arms I6 and I! are thus simultaneously reciprocated upon turning of the shaft 22 sothat the fingers I4 are raised and lowered inunison, as indicated in going from the solid in Fig. 2. In order to prevent the arms I 6 and I 1 from swinging rearwardlywhen' the weight of the waste is on the fingers I4, 'pins' 23 and 24 are respectively positioned behind the arms I 6 and I! to extend from the sides of the respective presses I3. As indicated, the forward terminal ends of the fingers I4 are preferably sharpened and turned slightly upwardly. The forward ends of the fingers I4 in the pres ent structure shown are positioned above a seeare employed, 7

2- ond wash tank 25 over which a plurality of picker rods 26 are reciprocated in fore and aft directions as well as being intermittently raised and lowered to convey waste through the wash tank 25, all in the manner as shown and described in said Patent No. 2,090,260. Immediately under the fingers M is placed a platform 21, herein shown as being inclined rearwardly and downwardly under the presses IS. The forward end of the platform 21 terminates a substantial distance back of the forward terminal ends of the fingers I4 as indicated in Figs. 1 and 3.

As the compacted waste is pushed out of the presses l3, this waste will be extruded therefrom in a solid mass until the weight thereof breaks off sections in the nature of rectilinear cakes several inches thick in most instances. These cake-like formations of the pressed waste drop onto the fingers Id between side arms 30 and 3| which are respectively fixed to the arms [5 and i1, and which are spring-like in nature. The fingers M are constantly being raised and lowered as indicated in Fig. 2, this action being sufficiently rapid to shake these matted cakes of waste up and down on the fingers id to divide the cake into smaller masses and eventually loosen the waste fibers to separate them one from another very effectively. As the waste is extruded from the presses (a rather slow travel), this extruding waste tends to push off the loosened waste from the fingers M to allow that loosened waste to drop down from the forward terrnianl ends of the fingers M. Fingers 30 and ti aid not only in preventing the waste rom falling off the fingers l4 sidewise, but tend to prevent masses of waste falling ahead over the ends of the fingers le before sufficient shaking.

As this loosened waste dropsfrom these fingers 54, it will become impaled over the ends of these fingers and as the fingers continue to reciprocate, the waste is thus further loosened up and pulled apart quite effectively. This action is further accelerated and carried out to a greater degree when the waste strikes the body of oil 28 in the tank where the oil absorbed and coating the lower end of the hanging waste will apply some additional weight to the waste and thus tend to hold the lower part of the waste down while the upper part is lifted and shaken quite effectively by those moving fingers l4.

Then as indicated in Fig. 5, the moving picker rods 26 will engage by their rear row into the loosened up waste directly under the forward ends of the fingers M and progressively pull and move that waste forwardly in the oil 28, further aiding in the separating and loosening of the waste fibers one from the other.

As above indicated, it is immaterial as to how the waste has been initially compacted, whether by the presses l3 or by a centrifuge. Where the centrifuge is employed, the waste, of course, must be removed by hand and in that case is dropped immediately on the shaker fingers M to be loosened up. In any event the-rapid vertical reciprocatory action of the fingers l4 bounces the waste up and down on those fingers and over the terminal ends thereof to such an extent that the waste is fiuffed up much more effectively than can be done by hand and at the same time here is no over-rolling action that would tend to form the waste into rolls as is sometimes the case where the waste is attempted to be tumbled following a compacting operation. While this reciprocating action is going on, any foreign material which has by chance not been removed further before the waste is compacted is effectively shaken out and caught on the platform 21. Also short ends that have not previously been removed will be shaken out and also caught on the platform 27. As may be noted, the forward ends of the fingers M are given a slight fore and aft movement by reason of the rocking of the arms l5 and H about the abutting pins 23 and M by reason of the upper ends of those arms having to follow the circle of travel of their connected crank pins l8 and I9. This slight fore and aft travel further aids in the action of fiumng up the waste and in its discharge from the fingers.

While we have herein shown and described our invention in the one particular form, it is obvious that structural changes may be employed without departing from the spirit of the invention and we, therefore, do not desire to be limited to that precise form beyond the limitations as may be imposed by the following claims.
