METHOD OF TREATING OIL-SOAKED WASTE.

Specification of Letters Patent. Patented Jan, 21,1913.

Application filed September 14, 1912. Serial No. 720,330.

To all whom it may concern:

Be it known that I, ISAAC J oNEs, a citizen of the United States, residing at Cheyenne in the county of Laramie and State 0 WVyoming, have invented certain new and useful Improvements in Methods of Treating Oil-Soaked Waste; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the method of renovatingoil soaked waste, such'as is used in journal boxes and like bearings, and has for its object to treat the waste in such manner as to completely remove the dirt from the waste, to remove the short pieces of yarn, dissipate and remove the glazed surface which ordinarily forms upon the waste next to the journal, to fluff the fiber in the yarn, and to efi'ect these several results without materially diminishing the oily or greasy content of the waste, so that the thoroughly cleaned oil soaked waste may be further employed without the necessity of-satu'rating the same with a new portion of oil or grease.

To this end, the invention relates to the method of cleaning dirt and the like from oil impregnated waste without materially diminishing the oily content, which consists in agitating subjecting the body of agitated waste to blasts of heated fluid medium, preferably steam, Which blasts traverse the waste in all directions forcing the dirt and foreign material out of the body-of the waste, expanding or fiufiing the individual fibers of the wastea'nd at the same time leaving the oily content practically intact in the body of the waste.

A relatively simple form of apparatus for carrying out the process is illustrated in drawings, in which is a side elevation of the said Fig. 2 is a vertical longitudinal Fig. '3 is a vertical Figure 1 apparatus; section therethrough;

' transverse section; Fig. tis a perspective 1 a hood or cover 3 of similar shape,

cover-is hinged at 4 to the frame 1 and is frame of wood or view of the spraying head employed inthe apparatus. I

Referring to the drawings, 1 indicates :a

2, semi-cylindrical in shape, above which is the waste and simultaneouslyother suitable" material in which is secured a-pan-like-receptacle which tion by a screw and thumb nut 5. The lower part of the portion of the receptacle 2 is provided with a discharge outlet 6 emptying into a suitable drip pan 7 Inclosed in the casing formed by the parts 2 and 3 and journaled in suitable bearings 8 carried by the frame 1, is a foraminous drum, preferably composed of an outer covering of wire mesh 10, attached to solid headsor end portions 11, which'latter are secured to the T-couplings 14, which in turn are provided with trunnions 12 engaging the bearings 8 aforesaid. The right hand trunnion 12 is formed by a supply pipe for steam or other fluid under pressure, which is connected by a suitable swiveling coupling 16 to the supply pipe 17 Connected to the T-couplings 14 and disposed as a rectangular frame within the rotary drum is a spray pipe 13 having perforations 15 which direct jets of the fluid medium radially, toward the axis of the drum and longitudinally or parallel with the drum axis. The left hand trunnion 12 is provided with a crank or other suitable means for rotating the drum and the spray pipe contained therein. One side of the said drum is provided with a hinged door 10 adapted to admit the waste to and discharge the same from the drum. If it is desired to rotate the drum automatically, steam or other fluid medium under pressure is supplied in jets which strike the peripheral surface of the drum at a suitable angle by means of a spray pipe 21 connected with the supply pipe 20, which latter, like the supply pipe 17 is provided with the usual form of shut-oif valve.

In operating the ap aratus journal boxes and the like-is thrown into the cylinderlthrough the hinged door in the side of the drum after which the door 10 'is closed and the hood-like member of the ca sto carryout the novel method, the 011 soaked waste from jets from the thoroughly permeate the same and as a consequence the dirt and short pieces of waste I 1 let 6 into'the drip.trough 7. The s aking L or agitation of the waste, together with the impingement of the steam jets upon the agitated waste also subserves the purpose of breaking up the glaze which is commonly formed on the surface of the waste adjacent the journals which is apparently due to a mixture of dirt and oil, which prevents. the oil passing through the waste to the journal and is a very common cause of overheating in the journals. It has been the common practice heretofore to attempt to remove this glaze and other foreign matter from old waste by shaking it up by hand which,,however, has merely the effect of distributing the glazed portion of the waste throughout the whole-mass without removing the glaze. By the present method, however, the glaze is not only fractured and broken away from the waste, but also so far broken up and dissipated as to admit of its being shaken out of the waste and carried off with the other foreign material. A still further result of the process aforesaid is the swelling or flufling of the fiber in the'yarn constitut- 7 ing the waste which isobviously a desirable feature and one which 'is not attained by any ofthe ordinary methods of cleaning orv renovating waste.

One of the most important results of the. process aforesaid is that, while 1t removes I like from 'oil impregnated waste without all dirt and other deleterious material from the waste, it does not extract the oil, but leaves the oily or greasy content of the waste, unimpaired and practically intact, distributed throughout the body thereof.- In all of the waste'cleaning processes heretofore employed, it has been the common practice to remove or wash out the oil so.

that when the cleaned waste was againused 1t was necessary to completely impregnate tle entire mass of waste with a fresh supply 0 oil.

lubricantcontained in the waste is carried off during the cleaning of the waste by the process herelnbefore descrlbed. To illustrate' by a concrete example, it requires approximately four pounds of lubricating oil to saturate. one pound of new waste or old waste washedor renovated by the .former .procesis;v In a series of operations, involving The present invention results in a. great saving of 011 in thatvery little of the improved process aforesaid. 1

In carrying out the process, it is desirable that the steam or other fluid medium be of a suflicient temperature tocausethe oilto. become softened without rendering it so highly fluid as to run' out of the waste and the pressure of the fluid medium should/be sufficient to cause the jets traversingthe waste to blow the .dirtand foreign. material out of the waste andpermit the same'to escape through the foraminous walls ofthe rotary "drum. Very satisfactory. results have been obtained in an apparatus such as illustrated in the drawings, with substantially dry steam at about eighty pounds pressure supplied to a body of waste. in the drum for approximately three. minutes, the

result being a thoroughlycleaned and. flulfed waste, ready for reuse and with its oily content practically unimpaired. i Y What I claim as my invention is 1. The method ofclean'ing dirt and the like from oil impregnated Waste without, materially diminishing the. oily content, which consists in. agitating the waste and simultaneously subj eating the same to blasts of heated fluid medium. 7

2. The method of cleaning .dirt and the materially diminishing the oily content, which consists in agitating the waste and simultaneously subjecting the same to blasts of steam. v

3. The method of cleaning dirt and the like from oil impregnated waste without materially diminishing the oily content,

which consists in tumbling the waste in the presence of blasts of'steam which traverse the materiaL- g I 4. The method of cleaning dirt and the like from oil impregnated waste without materially diminlshing the oily content, which consists in separating and loosening the waste by agitation and subjecting the separated and loosened waste to blasts of heated fluid .medium.
