To all whom it may concern.

Be it known that I, JAMES BAIwsLsY, a

citizen of the United States, residing at Akromin the county'of Summit and State ofOhio,'hav e invented new and useful Improvements imDevulcanizing Apparatus, of which thetollowing-is a specification.

Tl is invention relates to an apparatus for devu canizing ground rubber waste or other articlds composed of ingredients having rubber as the principal part thereof, the object of the invention being to provide a simple, cheap and eflicient apparatus of this class whereby all of the waste rubber is reclaimed, so that it may again'be'used' for any desired purpose.

With the above and other objects in view which will appear as the description progrosses, the invention resides in the novel construction, arrangement and combination of parts hereinafter fully described and claimed. I

=1n the drawings,'Figure 1 is a side elevation of a device constructed in accordance with. the present invention. Fig. 2 is a centrallongitudinal section of the same. Fig. 3 is a transverse sectional view taken upon the line 3-3 of Fig. 2. Fig. 4 is a similar sectional View taken upon the line 4+4 of Fig. 2.

- In the accompanying drawings, the numeral l designates a receptacle which is adapted to receive the ground rubber waste This receptacle is preferand chemicals. ably circular in cross section and has its inner faces lined with lead 2, or an analogous material which is not susceptible to the corrosive activities of the chemicals within the receptacle. I

{The receptacle 1 is centrally provided with two-or more manhole openings having surrounding collars 3, and whereby'the rubber scraps to' be treated as well as the chemicals may be inserted within the receptacle. The collars 3 are tightly closed through the medium of removable caps '1 the said caps as welljas the collars being provided with a coating of non-corrosive material. and the jointfbetween the'collars and caps being of such an arrangement as to hermetically seal the openings of the receptacle.

The receptacle 1 has its. inner portion provided with a plurality of spaced bafiiing plates, 5, the same being positioned longi tudinally of the said receptacle and having their offset or radiating portions formed with teeth 6 at the edges thereof. The teeth 6 of one of the baffling plates may be positioned to aline with the space between the teeth of the succeeding and preceding baffling plates, if desired, so that the rubber beingtreated within the receptacle will be positively contacted by the teeth and the said rubber thus rendered more easily so1uble and the composition formed with the rubbense arated.

The-co lars provided upon the openings forming the manhole are so arranged in relation to thereceptacle that the said receptacle will be counterbalanced thereby, and the collars 3 and caps 4 thus materially assisting in the rotation of the receptacle in a manner which will present-1y be set forth.

The receptacle 1 is provided at suitable spaced intervals with relief valves 7. These valves 7 are positioned a suitable distance adjacent the openin s provided by the manholes and the said valves are protected through the medium of suitable reticulated coverings designated by the numeral 8. The said coverings are preferably of a rectangular formation having an open bot "tom, the sides and ends of each of the said coverings being reticulated as heretofore set forth and each ofthe said covers being constructed of some suitable material not susceptible to the disintegrat-in effects of the chemicals within the receptac e. The receptacle is adapted for rotation and is centrally provided upon itsopposite ends with enlarged pipe members 9. Each of the said pipe members is mounted in a suitable bearing 10, the said bearing being preferably provided with anti-frictional balls secured upon the pipes or hollow shafts 9, the said pulleys being connected through. the medium of suitable belting with a source of power and whereby the receptacle 1 may be rotated. Each ct the hollow shafts 9 have their free ends @provided with packing boxes 13 and l lik, l?ositioned within the hollow shaft, 9 having the packing box 13 is a pipe member 15, the latter being provided with a suitable valve 16, the purpose of which will be presently apparent.

Y The hollow shaft 9 provided with the connected with a water pipe 20. T e in- E jectorjgmty' be of any ordinary or preferred construction, and is provided with the usual operatln handle whereby the steam is allowed within the said injector to pass therefrom through the pipe 17 and hollow'shaft 9, to the race tacle -1-. The water pipe is provided-wit th'e'usual valve 21 and the injector is' also provided with. an overflow pi e 22.

xtending' longitudinally within thereceptacle -1-1s a perforated'pipe 23. This pipe has-one of its ends closed and its opposite end, communicating with passages provided by the hollow shaft 9, pipe 17 and injector 18.; The closed end of the pipe 23 is retained in position through the medium of a *suitablesupport 24, while the outlet provided by the hollowshaft connected with the pipe 15 is protected through the medium of areticulated member. 25. V

Briefly stated, the operation of the device is as follows :--The ound rubber is insorted through one o the manholes of the receptacle 1, together with a sutlicient amount of chemicals which are adaptedfi) assist. in the process of reclaiming the rubher from the composition formed with the rubber, The valves are all closed. The cap .is re laced up on the manhole and power is applied through the medium ofonenf the pulleys to rotate the receptacle 1. Thein- 'ector is then sets-so as to allow steam to passthroughthe pipe .19 and hollow shaft 9 into the perforated pipe 23'. The steam is ejected through the minute perforations of the pipe 23 in'either direction, so that the radiating sprays/contact the rubber pat tides and the chemicals. This process 18 keptup. for a number; of hours and when sufficient time-has lapsed to, thoroughly soften the rubber to permit the partlcles comprising the composition to be removed therefrom, the steamfrom the injector is stopped and water is allowed to flow through the pipe 20 tothe reticulated pipe 23. The injector is thenoperated so that the steam from the pipe. 19 will act upon the-water from the pipe 20 so as to force the same. rapidly through the perforations.

After mingling the water andsteam with the chemicals-within the receptacle for a suflicient length of time, the inflow of. water andsteam-is cut a.; The lowermost valves v:7 are' then opened and the Wallet is'per mitted an outlet. Afte'r"a1l the water has been removedfrom'the receptacle one of the capsAjs removed'from the'manhole' opening and the reclaimed rubber withdrawn froin the receptacle.- 7

It is tobevunderstood that the valve 416 connectedw'ithth pipe 15 is'opened when valved outlets in said receptacle,

.on one plate ,tweenjthe teeth on the .low' shafts'carried by. said receptacle and the steam and water are allowed to enter the receptacle 1, so that the base or composite material may find an outlet through this pipe 15, It is to be further understood that when steam alone is being injected within the receptacle 1, the valve 16 is closed, so

that the steam and chemicals are allowed a full and free act-ion upon the rubber and composition.

Having thus fully described the invention, what I claim as new, is

1. A device of the class described comprising a cylindrical receptacle, a lining of non-corrosive material, diametrically opposite man-holes in said receptacle, removable closures for saidman-holes, a plurality of diametrically opposite valved outlets for said receptacle, reticulated protectors for said. valved outlets carried by the non-corrosive lining, hollow shafts carried by said vreceptacle, supports for rotatably mounting said shafts, means whereby said shafts may be operated, a reticulated protector carried bye-lining"from one of the shaft openings, a pipe mounted within the other hollow shaft and extending into the receptacle, the inner portion of said pipe "being perforated and having its end closed, and means by which jfiuid may be injected through said pipe into communicatmg with its end openings,

which said shafts may be opmeans .by

era-ted, supports for rotatably mount-ing said shafts, a fixed pipe mounted with. one of said shafts and extending into the receptacl'e, the nner portion of said pipe be ing enlarged, perforated, and. having its endclosed, a fixed external support for said pipe, means ceptacle' through said perforated plpe, and means whereby the flow of liquid may be regulated;
