WASTE SEPARATING SHAKER Filed Nov. 14, 1951 4 Sheets-Sheet 4 l5 INVENTOR, H' I Lou/5 J. Sci-IA .IEFEP, 15) W0 m H7 TORNE x United States Patent 2,697,256 WASTE SEPARATING SHAKER Louis J. Schaef er, Milwaukee, Wis, assignor' to Journal Box Servicing Corporation, Indianapolis, mm, a c'orporation of Indiana Application November 14, 1951, Serial No. 256,185" 9 Claims. (Cl. 19---81=)- This invention relates to a device for loosening and separating one from another strands and fibers of journal box waste whichhas previously been soaked in oil. The device finds particular use in the operations of cleaning used journal box waste through such processes as are embodied in the United States Patents Nos. 2,000,291 and 2,090,260.

In using the oil extracting mechanism of Patent No'. 2,090g260 as shown in Fig. 6* therein, the waste' will leave that extractor in a more or less matted and compressed condition in leaving this extractor, the; waste has previously been: put through a dehydrating and awashing op eration and then is to go on to a reoiling operation. The operation is better carried out if the waste is shaken loose and carried through the reoiling operation in a more or less separated fiber conditions Heretofore, the matted and compressedwaste in leaving' the extracting device of this Patent No. 2,090,260 has been initially dumped intothe reoiling device, but later dumped onto a shaking table where the waste would be pulled apart and separated by hand. Then the separated waste would bepassed on into the reoiling mechanism.

The present device is installed between the waste extractor and the reoiling mechanism so that the process may be continuously carried on in an automatic sequence without having to interrupt the process by intervening hand operations.

A great advantage of the present invention lies in the fact that it will receive the matted and more or less pressedwaste" and gradually separate the fibers and loosen up the entire mass into a more or lessfluffed up condition so that the waste will eventually be in a condition to receive oil quite readily. There must be a resilience to the waste body in order to makeit elf'ective when finally returned to journal. boxes for use. In this present inven-' tion, the waste is restored to this loose and resilient condition by an operation which is exceedingly gentle in re spect to the waste, that is the operation will not cut and break the fibers to any extent so: that the' fibers are not reduced, in length;

The device will gently pull and shake up thewaste until. it is restored to the highly desired condition of being loose and resilient In describing. the invention, reference is made to the accompanying. drawings in which Fig. l is a View of the device in front end elevation;

A rectangular framework herein shown as being made out of angle bars ismade out of the cross andv side elements 10, 11, 1 2;. and 13; This framework generally designated by the numeral 14 issupported by corner legs 15. Base legs-l6 support the legs 15 in such: a manner thatthe. rear end bar 10 is held atahigher elevation than: the front bar 11,v the difference inelevation being in side elevation of an opposite side v which will 2,697,256 Patented Dec. 21,. 1954 2 approximately five inches for an overall length of the device of approximately four feet.

A- finger element generally designated by the numeral 17 isformed tohave a bar 18. This bar 1 8 is provided with a plurality of long fingers 19, herein shown as 18 in number. Each of these fingers 19 is secured to the supporting bar 18 by any suitable means such as by welding and extends therefrom in a free, cantilever manner so that the ends 20 are free. These fingers 19 are spaced apart in parallel relation a suitable distance suc as for example on two inch centers. Then behind the last finger 19; there is a series of shorter fingers 21 likewise carried by the supporting bar 18' to extend in parallel relation to the fingers 19 and in spaced apart relation to have the same spacing therebetween as that of the fingers owever, as compared to the length of the fingers 19', which is approximately twenty-six and three quarters inches from the bar 18' to the tip end 20, the shorter fingers 21 each have lengths of approximately eleven inches. In the form herein shown, there are seven of these shorter fingers 21'.

There is provided a finger assembly generally designated by the numeral 22 to have the supportingbar 23 carrying. the long fingers 24 and the series of shorter fin gers 25, these fingers 24 and 25- corresponding in number to those carried by the bar 18.-

There are fixed to the bar 18 a: pair of spacedapart hinge arm assemblies 26 and 27 respectively, these arms being turned outwardly and upwardly from the bar 18 at an angle of substantially one hundred andthirty degrees. These assemblies 26 and 27 carry bearing ends 28 and 29 respectively which are rockably supported in the bear ingv blocks 30 and 31- which are mounted on the posts 15. Likewise the unit 22 has the spaced apart arm assemblies 32 and 33 to each carry the bearings 35 and 36 respectively to interengage in bearing blocks 38 and 37 respectively. Thus the finger assemblies 17 and 22 are rock;- ably carried to swingbelow the top frame members 10, 11,. 12, and 13'. V r p These two assemblies 17 and 22 are rockabl-y interconnected by means of a waste pan 39, this pan 39 c011 sisting essentially of a fiat plate with an outer upturned rear flange 40. The pan 39 carries at opposite ends a series of clips 41 and 42 respectively, each of these clips being identical, and having a circular eye- 43 of widths permit the clips to slidingly pass between the lower ends of the fingers 21- and 25 respectively, and receive a rod 44 and 45 through theeyes 43 respectively; The rods 44 and 45 passthrough' holes 46 and 47 provided through the lower ends of the fingers 21 and 25 respec-'- tively, Figs. 5 and 6; p

On the underside of the pan 39 there is secured a pair of downturned brackets 48 and 49 spaced apart sufficiently to receive therebetwcen the end of an eccentric rod 50 to have the brackets 48 and 49rockably support that rod 50 by means of a cross pin 51 which extends through holes 52 and 53- provided respcctively in the-brackets 48 and- 49.

This eccentric rod 50 extends under the pan 39 and is connected to an eccentric 54 which is'fixed on a fore and aft shaft 55 mounted to revolve along theoutside of the legs 15 in the bearings 56 and 57. The eccentric 54 is secured to the rear portion of the shaft 55. A' sprocket 58- is also fixed on this shaft 55 ahead of the eccentric 54 and carries a chain 59 which extends around a sprocket 60'fixed on an upper shaft 61 which is carried in parallel relation to' the shaft 55 by the bearings 62 and 63.

On the front end of the shaft 61 there is fixed a pulley 64 around which extends a belt 65 from a pulley' 66 mounted on the shaft of a driving motor67. Thismotor 67 is mounted on a plate 68 which extends across the front end portions of the rails 12 and 13 and over the front rail 11.

On a number of the fingers 19 and 24' first appearing ahead of the shortfingers 2 1 and 25 there are fixed longitudinally therealong and toextend upwardly therefrom in each. instance a toothed comb 70 and "ii respectively. In the present showing, the first ten of the long fingers 19 and also 24 carry these combs 7i and 71 respectively, the succeeding fingers from then on to the discharging end: are left without the combs; The lower ends of the fingers 19 and 24 have their end portions 20 and 72 curved slightly upwardly as indicated in Figs. 1, 5, and 6. Across the rear bar and the rear portions of the side bars 12 and 13, there is fitted a short downwardly and forwardly extending guide chute 73. The lower front edge 74 of this chute 73 is vertically disposed over the pan 39. The upturned flange 40 extending rearwardly and upwardly from the pan 39 is behind this edge 74, Fig. 3.

Operation When waste is to be fed into the device described, the motor 67 is set into operation which will drive the shaft 61 and in turn drive the lower shaft 55 at a speed reduced from that of the motor since the pulley 64 is larger than the pulley 66, and likewise the sprocket 58 is larger than the sprocket 60. Turning of the shaft 55 will cause the eccentric 54 to revolve and thus reciprocate the eccentric rod 50 in a generally transverse direction across the device, and thus will reciprocate the pan 39 accordingly. As the pan 39 is reciprocated, Fig. 1 it will rock from the solid line position which is the position at the extreme right hand end of travel, to the dash line position which is substantially the extreme end of the left hand travel, the chute 73 being at the rear end. Waste is then dropped down over the chute 73 to allow it to fall initially between the finger assemblies 21 and 25 to drop onto the pan 39, and as the assemblies 21 and 25 are rocked from the full line positions to the dash line positions and the reverse as indicated in Fig. l, the waste on this pan will tend to be kicked from side to side as well as bounced upwardly slightly, and since the finger assemblies 21 and 25 are inclined as indicated in Fig. 2, the waste will tend to fall forwardly along the fingers 19 and 24.

As the waste leaves the pan 39, the combs 70 and 71 will engage in the waste and will gently tend to hook into the matted fibers of the waste and pull them out into straight-end conditions by the waste fibers hooking over the teeth of these combs. The pulling apart is relatively slow, and is reversed since the comb 70 will initially be in an upward position with the comb 71 in a lower position, to carry the comb 70 downwardly and the comb 71 upwardly as the finger assemblies are rocked. The curved lower ends 20 and 72 of the fingers 19 and 24 tend to prevent the waste from dropping through between these lower ends so that the waste is gently carried outwardly and downwardly from between the fingers to discharge from the outer extreme fingers 19a and 24a, Fig. 4. By reason of the offset arrangement of the mounting of the supporting bars upon which the assemblies 17 and 22 swing, the teeth 19 and 24 are relatively spread apart by their upper ends in that swinging action as will be noted by the travel for instance of the fingers 19 from the solid line to the dash line positions. The axes of the bars 18 and 23 are in a plane parallel to the top sides of the side bars 12 and 13.

The presence of the pan 39 prevents the waste from dropping through between the finger ends 20 and 72 when it is initially dropped between the assemblies 17 and 22, so that the waste will be engaged by the combs 70 and 71 immediately it leaves the pan 39 thus to be carried along between the fingers rather than tending to slide on downwardly therebetween until the waste is pulled apart and fiuffed up sufficiently to maintain it between the assemblies until it is discharged over the fingers 19a and 24a at the discharge ends of those finger assemblies.

Thus it is to be seen that I have provided a very novel structure for the purpose intended, operating in a very simple but most effective manner. It is obvious that structural variations may be employed without departing from the spirit of the invention, and I therefore do not desire to be limited to that precise form as described, beyond the limitations which may be imposed by the following claims.
