Be it'known that I, GEORGE Anno'i'r, a-

. a citizen ofA the United States, Vand resident of Hartford, in `the county of Hartford and 'State' Iof -'.Connect icut, have invented `certain newand useful Improvements in Tumblin Barrels, of whichvthe following is a fu, clear, and exact specification. i y

This invention 'relates to tumbling barrels, and more. 4particularly to that class thereof inwhich a solution maybe used yin conjunction Withthe articles tobe treated, so that the lat't'er'may` be burnished, or have a high `polish imparted thereto which result 4islattained by the employmentotl 'olished vsteel ballsgofdii'erent' sizes so as to a apt the work to'be Ytouched. jand burnished in even .the smallest `crevices or depressions. A Thefinventionhas, 'for oneof` its `objects the pro-vision of an `apparatus of this naturekwhic'h might be termed elastic, or ,in other "ofthe sections may be independently ven-ted adjacent sections can occur, the ventin and in such a manner that no Ainterrninglin'g between the solutions contained yin a pair of feature 'being essential inasmuch as by 1t all excess. of pressure which may be establishedby theI vaporization due to the churn- Jing'of the solutions durin the rotation of' the barrel may be carried o and all danger lof bursting due tol such pressure be lentlrely f A avoided.

a pair 'of adjacent units, and Fig. 4 is a deta1l"il1ustratin the reliefva1ve whereby e vented. v y 1, The tumbling barrel shown in the accom-y panying drawings consists ofy three independent sections or units A, IB and C ywhich are of; comparatively narrow width lcompared with. the 'diameter thereof. Incidentally, it may be mentioned here that practice has demonstrated: that-theocta on form shown in Fig. '2 lis by virtuebf t e an larity of its adjacent sides wel1adapted or the use for which the barrel is to be employed es ecially when considered in connectipn `with the solution which is contained within each unit and' which would cause the 4barrel simply to slip around the work, with`4 out really producing the tumbling yorabrading effect whichit 1s.`to accomplish between the'burnishing balls and the work.`

Referring .to Fig. 1 itl will be seen that' the barrel comprises a'pair of heads 10.and 11, respectively, between `which the' difevlw` ent 'units are disposed and which have trunnions 121 and 13, respectively, journaled bearings 14, 1'5 of suchheight as to leave for the purpose of Vemptying ythe contents thereof. Interposed between the heads 10 recessed to receive the adjacent memberV and hold the same in concentricrelation therewith. It Willbe noted that theflange 17 of the spacer-'ring ,16 of the unit A isp-fitted over the head 10, lwhile the flange 1 8'of said'- .ring 16 -is adapted to enter the circular re-r cess provided n the flange 17 1n the spacer ner thel flange 18" of the spacer-ring r16 eninthe spacer-ring 16" whichhas a ilange 18` '-sulicient room beneath the barrel to permit a boxor truck to be run underthe barrel .Y

a and 11 are a seriesof spacer-rings 16'` pref- .erably made of `cast i-ron vand all similar shape and each having/a `fiangel'- which 1sv a i adapted to enter the.v recessin 4theh'ead `11# V.

Ino'ther words, it will b'e noted that the spacera-ings'll, 16', -16;are all? alike and i that anyl one of them can -fbe removed orfinterchanged with any other of the series, and, furthermore, that the head 11 can be brought into coperation with the spacer-ringy 16--111-1'1 asmuch ast Ve flange 18 will also be adapted .to :enter the recess in' the head 11.v

By. virtue of the great circumferential andl faceVA contact between the severalnnits or spacer-rings and the endeheads '10 and 11, tebarrell as a whole is entirely self-support ging, without', any central' supporting means ,exceptithe trunnio'nse12 and 1 3, above men- "tionedp e l -,Practi'ce 'has demonstrated that different articlesrequire diierent solutions and also different sized balls to performthework,

and for this reason the several unitsA, B, .C `are entirely separated from each' other, as

for instance by partition-plates 2O prefer-- ablymade of boiler iron, and of adiameter s o.' that they' willenter the recesses inthe l several spacer-rings, above referred to, and

l ...in-such a manner that the adjacent ianges of the'spacer-rings will clamp the partition s. lates between them Whilefmany diferent methods may be employed for drawing the' several units together, I preferably use bolts 2 1',- extending-across one unit, so as to serve also as a handle whereby the barrel or unit .may be' turnedby hand when desired, as for u Y' are preferablyofpolygon shape, and which 'are lined with circumferential strips 24 of hard n1aple, so as to protect the articles to .instance when the unit is to be loaded or.

-vdischa'rged For the latter pur ose the barrel is provided withv opposit ly disposed openings 22, 23 in .the spacer-mugs` which be operated upon lifrom contact with the metal. .Likewise theside walls of the units f are protected by wood linings 25 and 26.

The openings 22, 23, above referred to, extend naturally also through' the linings 24 and are normally closedby covers 27 also made vof wood and fitted into said openings, so as ,to constitute a continuous lining for the units, respectively. Each' of the covers y27 is forced into and held in place bya swivel-lever 28 fulcrumed oni a stud 29 the latterv being-'secured to the cover-block which is secured to'a metal cover-plate 30,

i. 27, as for instance by screws 31 'and packed on to its respective spacer-ring by packing 32'.

posed on vthe flanges (see also Fig. 2).

The ends'of` the .swivel or clamp-lever `28 are adapted to engage cam lugs 33, 34 dis` 17 and 18, respectively It will, therefore, be noted `that when the two covers'of` a unit are clamped in place, the `chamber lof this unit is hermetically closed. Now, inasmuch 'as theconstantl friction 'and churnin 'of the. solution which takes place when the ari "'rel is in operation has a tendency of vaporizing the solution or convertingfthe same into steam whichif not released would establish pressure within the unit chamber,

means areprovided whereby such pressure, will be released or carried off., In order to l i 97de?? accomplishl this result, deem it essential o that each unitbe vented independently and without interfering with`the adjacent unit,

and also'theposition of the' vent opening shall be as neara neutral. pointas possible, so that anyl leakage of solution, or the passage of articlesto be treated or the burnishf ing balls, shall be avoided. Hence, I prof vide near the center of rotation of eachunit an aperture 40' extending'through Athe side' lining, this aperture 40 ing connected by means of a radially extending conduit or duct 41 lwith a pocket 42 which is adapted toi-receive' a rehef-valve 43, serving atthe same time as a lockingmeans for prevent-` ing shifting movement between the, lining 26 and the spacer-ringto which it pertains.

.Inorder to guard against'any ofthe articles or burnishing balls from entering the aperture 40 whereby the conduit 41'might be vclogged and the proper venting lof-'the unit be interfered with, I preferably'employ a screen S. consisting either of wire ses gauze or a foraminated plate which isfse cured to the lining 26,'as shown in Figs.` 1' and 2. f

The-relief-valve 43 is screw threaded into the spacer-ringwhich is4 provided with la as controlled. by a ballvalve 45 which is normally seated by a sprlng '46 containedin vent opening 44 throughwhich the gases or I I)excess pressure-may pass to the atmosphere the 'valve-casing. This spring may be made any required stiffness, and .so that it will.

permit the ballvalve 45--toopen as soonas certain pressure'exists within the unit-casing.k It should be noted at this time that -I do not confine myself to this particular con-y struction since many ways and methods may accomplish this result, and

be employed t-o fact, the relief-valve itself as a matter yof `may be entirely dispensed with, but its use short boltsl `which extend -onlyy through the adjacent flanges of saidsections, aconstruction which exists only at the particular places to intenifferev with their ready removall or insertioni The particular reason'why apair of such openings are providedsubstantially jat diametrically opposite points in .eachunit is to facilitate/the discharging of the contents of the unit, the lower cover being open "where the covers are located so as notv losv lto Fig. 3, lt'will be noted that the several' y sectionsor' units are connected by means of .f weer? to :release `the contents,A while the* upper .cverrnay be'removed sogas to aiford access to the interlorfor cleaning out purposes.

' Anysuitable drivingpmechamsnrmay be employed A"for rotating, the barrel on its trnnnions, such .mechanism being shown .herein as' tightl and loose pulleys 'P and P',

respectively', which -are'securedto the trun` nien-12 `of the end-head 10. y y' Inhrief, a barrel made in accordance with the present .invention possesses many features not found heretofore especially as far 'asv-its practical-'utility and its faculty of be ing extended or'contracted according to the vrdemands, 'is concerned. Other yunits may readily be 4added by unskilled help inasfmuch as the 'several units are'K interchangeable and 4arefall made to standard slze..

-Likeyvism solutions. of different kinds and .also 'articles .of diji'er'ent characters may be laced 'into the,units respectively, and tum'-v led; for the required len h of timewhen erence to the adjacent. unit.
