The present invention relates to a process for cleaning the waste used in railroad car Lournal .boxes and machinery therefor and as for its prime object to provide an econom- 5 ical process which will efliciently clean the waste without destroying the fibers thereof and machinery for accomplishing the steps of the process.

Generally the invention consists in pressall the oil and some of the dirt and grit from the old waste and delivering the same practicall dry to a combing machine. This com ing machine eliminates lumps in the waste and draws the same into threads 15 and causes the formation of a relatively thin This comparatively thm layer of waste.

' layer of waste is delivered to another machine having a conveyor and means for rubbing the waste back and forth on the con- 20 veyor and simultaneously delivering a stream of clean hot oil over the waste. his clean hot oil assisted by the rubbing works all fine substance loosefrom the waste. The hot oil draining from the waste is filtered through a gauze screen to be heated and used over again. The waste is delivered to what is known as a sorting table which allows the surplus oil to drain off after which the waste ,may be packea 1nto drums ready for use again.

With' the above and numerous other 9bjects in view as will appear as the description prceeds,the invention resides in certain novel steps in the recess and certain novel details of constructlon, and in the combination and arrangement'of parts in the machinery as will be hereinafter more fully described and claimed.

therethrough taken substantially on the line 7-7 of Figure 5.

Referring first to the apparatus as shown in Figures 1 and 2 for squeezing the oldoil from the waste, it will be seen that the numeral denotes, a tank supported between corner legs 10. These legs 10 support side rails 11 and end rails 12. Bearin' blocks 7 are slidablymounted on side rai s 11 as is indicated at 14 and have ends of rollers 2 and ends of rollers 15 journalled therein. Rollers 2 are smaller in diameter than rollers 15. Springs 16 are interposed between the bearing blocks 7 for urgm the rollers 2 of each palr toward each 0t er. Shields 17 are mounted on side rails 11 by means of straps 18 and cover rollers 15 and terminate adjacent rollers 2. Hopper 1 is mounted on shields 17 so that the cotton may be placed in the hopper 1 by hand and when the rollers are in operation will pass between the rollers 2 and e ressed thereby. Blades 20 are journalled etween side rails 11 and through cranks 21 and spring 22 are yieldably held in engagement with rollers 2 to scrape any waste therefrom which may have a tendency to stick thereto. The waste and the oil, therefore, will fall into the tank 5. A conveyor frame 23 is disposed on an incline and leads through one end of the tank to the interior thereof and has an endless screen member 24 trained over rollers 25 journalled at the ends of the frame 23 and operable in any suitable manner so that the waste will fall on the upper run of the conveyor structure which is moving upwardly and be led from the tank while the oil flows and collects in be drained ofi at 26 and any conventional or preferred ears 26 are mounted on t e rollers 2 and mesh with each other. A beveled gear 3 is fixed on one of the gears 26 of each air and meshes with a beveled gear 4 carried y a filtered b drive shaft 27 operated by a motor 28 or in figures is made upof a pair of legs 29 at each adjacent one end for.

end and a similar pair supporting a pair of lower side rails and a pair of upper side rails 31. A platform 33 is supported .on the intermediate legs and one pair of end legs as at 34 and has teeth 35 rising therefrom and arranged in series, each series of teeth being disposed below a rod 36. These rods 36 are supported on cross members 37 and 38, the former of which is disposed between the intermediate legs and the latter of which is disposed below downwardly inclined extensions 39 of rails 31. Side rails 40 are disposed between the pair of intermediate legs and one end air of legs 29 a slight difference above and 1n parallel ism with the plate 33 so as to form slots 41. The numeral 42 denotes a plate having a plurality of teeth 43 depending therefrom and extending in between the rods 36. An axle 44 is fixed to the plate 42 and extendsthereacross and beyond the side edges thereof. Bars 46 are slidable on the sides of the plate 33 and have humps 47 mounted thereon for engaging rollers 48 journalled at the sides of plate 42. Pintles 49 project laterally from the bars 46 through slots 41 and are engaged with pitmen 50. Pitmen 51 engage the ex tremities of axle 42. An operator gear 53' is actuated in any suitable manner and 55 meshes with a gear 56 meshes with gear 54 having co-axially fixed thereto a gear 55. The pitman is eccentrically mounted on the gear 55. The gear with which the pitman 51 is eccentrically connected. The gears 55 and 56 are so meshed that the movable portion of the comb including plate 42 and its teeth 43 will be lifted on its rearward movement toward the gear 56 as the bars 46 will be moved forwardly so that the hum s 47 will engage the rollers 48 to effect this li ing and then the parts will be moved rearwardly together and the plate 42 will be moved forwardly before the bars 46 so that the rollers will roll off the hump and the movable comb will move the waste forwardly on the stationary comb formed by the plate 32 and the teeth 35, thus threading the waste to remove all humps and forming the same into a thin la er.

eferring now to Figures 5, 6, and 7, it will be seen that the numeral 60 denotes a

tank havin frames

61 and 62 of an inverted U- s'ha e structure as is clearly shown in Figure to straddle the same.

Hexagonal rollers

62 and 63 are rotatably mounted in the top of the tank and have trained thereover an endless perforated conveyor 64 having seotional side flanges 65 extending outwardly therefrom. The waste is delivered from the rake mechanism shown in Figures 3 and 4 to the left hand end of the endless conveyor as shown in Figure 5. A corrugated rubhing pan 66 is mounted on

rods

67 and 68 carrie

y bell cranks

69 and 70 respectively. These

bell cranks

69 and 70 are pivotally mounted on

frames

61 and 62 respectively and are connected by connecting rods 71. The rubbing pan 66 extends between the tops of the inverted

U-shaped frames

61 and 62. A shaft 73 is journalled in the upper portion of the frame 62 and is driven by a pulley wheel 74 and has a chain and sprocket connection 75 with a pump 76 and another chain and sprocket connection 77 with a shaft 78 on one side of the tank 60 for driving a disc 79 having an off center abutment 80. A ratchet wheel 81 is operatively connected with the drum 63 and with a crank 82 and is engageable by the abutment 80. A pawl 83 is mounted on the crank 82 for engaging the ratchet wheel 81. A link 84 connects the crank 82 with the adjacent cantilever 70. An eccentric 86 is operatively connected with shaft 73 for operating a pitman 87 connected as at 88 with pan 66. The pan 66 is perforated and a pipe 89 rises from the pump 76 and extends longitudinally over the pan 66 and is apertured as at 90 for the purpose of spraying hot oil on the pan, said oil being heated by thermostatically controlled coils 91 in the bottom of the tank 60. Upon operation of the pulley 74 the shaft 7 3 causes the rubbin pan 66 to move back and forth and the bell cranks raise the pan on its backward movement and the conveyor operates with an intermittent motion so that the waste delivered thereto is thoroughly rubbed and is saturated by the oil sprayed onto' the pan 66 which drips through the apertures thereof and saturates the waste and also cleans the waste of any foreign matter therein. The crank 82 is returned by spring 95 and is limited in its return movement by an adjustable stop 96. A deflector structure 97 is mounted between the upper and lower runs of endless conveyor and has sections inclining to the side and downwardly so that the oil from the perforated endless conveyor 64 will drip thereon and flow to the side of the tank and then down onto the deflectors 98 which incline downwardly and inwardly so that all of the oil is delivered to a gauze sheet 99 disposed over a supporting structure 100 above the oil in the bottom of the tank and thus the oil is cleaned by the gauze sheet 99. This gauze sheet is referably about twice as lon as the tank and is wound on a roller 101 and windable on a roller 102 so that when one half thereof has become dirty the other half may be brought over the supporting structure and the previous half cleaned.

It is thought that the construction, operation, utility, and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof. The present embodiment of the invention has been disclosed in detail merely by way of example since in actual practice it attains the features of advanta e enumerated as desirable in the statement a? the invention and the above description. It will be apparent that changes in the details of construction, and in the combination and arrangement of parts and in the steps of the process may be resorted to without departmg from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advanta es.

Having t as described our invention, what we claim as new is 1. A process for cleaning waste comprising, first pressing oil from the waste after use, secondly raking the waste, and thirdly, simultaneousiy rubbing the waste under pressure and saturating and cleaning the same with hot oil.

2. A process for cleaning waste comprising simultaneously rubbing the waste under pressure and saturating and cleaning the same with hot oil.

- oil from the waste after it has been us 3. In a recess for cleaning waste, the step of subjecting the waste to pressure between two relatively movable members, moving such members to subject the waste to a rub bin action, and simultaneously with such I rub ing applying hot oil to the waste.

- 4. A process for cleanin journal box waste subsequent to use, comprising pressin old and subsequently raking the waste and saturating and cleanin it with hot oil.

5. A process or cleaning journal box waste subsequent to use, comprlsing pressin old oil from the waste after it has-been use and subsequently rubbing the waste and simultaneously saturating and cleaning it with oil.

In testimony whereof we aflix our signatures.
