- This invention relates as indicated, to apparatus for handling cylindrical articles such as barrels and the like, and 1s deslgne'd primarily'to be employed as a means for the art of coating and treating barrels, any

mechanism that is employed in connection with the treating apparatus for the purpose of feeding thereto, the cylindrical articles to be treated must be capable of feeding such articles singly, inasmuch as the treating operation is carried on in connection with only one of such articles at a time, and further, such apparatus after the feeding operation has been completed, must be capable of being positioned so as not'to'interfere with the workmen who are employed in the process of painting or treating the articles. 7

Another requirement of the above described form of material handling apparatus, is that when the feeding operation has been completed, such apparatus will of itself return to the inoperative position so'as to move out of the way of the operators, and further that while in such inoperative position, the feeding of additional articles will be restrained until the operator elects to so feed a new article.

It is among the objects of my invention to provide an apparatus for handling cylindrical articles which shall have all of'the above named desirable characteristics. Other objects of my invention will appear as the description proceeds. To the accomplishment of the foregoing and related" ends, said invention, then, consists of; the means hereinafter fully described and particularly pointbarrel painting or coating machine which ineludes opposltely tapered conical rollers 2,

adapted toreceive the barrel and support the same on-its chime rings duringthe painting.

'or' t eating operation, A pair of laterally spaced discharge skids 3, may be positioned in association with the paint machine'to carry away from such machine, the barrels orlike articles which have been freshly painted. In alignment withthe paint machine maybe an inclined conveyor down. which the barrels, or like cylindricalarticles are permitted to roll freely so that a new barrel is always in position to be fed to such machine by the apparatus J comprising my invention, which willnow be described.

Theapparatus for feeding the barrels from the conveyor 4, or like means to the, treating machine, or like means, consists of'a rotatable shaft 5, which may be terminally provided with trunnionsfi here shown rotatively mounted in bearings carried by pedestals 7. The shaft 5- has secured thereto, the axially spaced pivoted laterally spaced arms 8 and 9, a

which serve as a means for conveying the barrels or like articles from the inclinefcon- Veyor 4, to the above described machine, or like means.- The arms 8 are provided with oppositely sloping terminal portions'lO'and 1 1' which are perfectly arcuate in formalthough such arcuate form isnotnecessary to theopera-tionofthe apparatus. The space between the oppositely sloping portions-1O 1 and 11 may be filled with a counterweight 12,

which will beof sufficient mass sothat the tainedthereby in the substantially vertical position illustrated by broken lines in Fig. 2.

' arms of the apparatus will be normally main- The arms 8 and 9, as well as the terminal portions 10 and 11 thereof, are formed'from a plurality of'plates such as 13,, which are in overlapping relation along their ends so :as

to provide oppositely-sloping upper surfaces for theIarmsS and 9, andtheir terminals l'o and 11, so'thatthebarrel, or likecylindrical article, will be supported only. on its chime rings or on the periphery thereof adjacent its ends so thatno-part off'the mechanism portion ofthearticler p The operation of the above described apparatus is as follows:

The arms 8 and 9, due tothe effect of the counterweight 12, or the weight of the termi-- nal portions 10 and 11 on the opposite side of the vertical plan passing through the ful crum point for the apparatus will normally be in the broken line position illustrated in Fig. 2, so that any barrels or cylindrical articles such as 15, positioned on the inclined conveyor 4, will be prevented from rolling off from the end of such conveyor.- Upon counter-clockwise rotation of the arms as viewed in Fig. 2, the oppositely sloping'arcuate portion 10 and 11 of the arms will cause a'single cylindrical article such as 16, to be fed to the machine in the manner which is apparent from an examination of Fig. 2. The arcuate portion 10 will engage the next succeeding barrel or cylindrical article and positely laterally sloping article-engaging arms adjacent said conveyor provided with longitudinally extending oppositely laterally sloping portions for engaging such articles only on their chime rings andfor singly feeding such articles from said conveyor onto said arms upon pivotal movement of said arms. v

prevent the same from rolling down the con- 7 i veyor during the feeding operation of the article 16, and permit thearms upon release by the operators, to again resume a substantially vertical position preparatory tos the next feeding cycle."

It is believed that a further description of the principles described in my invention is unnecessary for those familiar with'the art, suiiice it tosay that numerous minor changes in the above described construction may be made without departing from the principles of my invention, and "Without losing any of the desirable advantages obtained thereby.

. Other modes of applying the principle of my invention may be employed instead of the one explained, change'being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed. Y r I therefore particularly point out and d1stinctly claim as my invention:

1. In apparatus of the class described, the

combination of a pair oflaterally spaced arms articles upon an inclined conveyorand'singly feed the samelon to said arms upon pivotal movement thereof.

.2. In apparatus'for singly feeding cylindrical articles from an inclined supporting means on to other receiving means, a pair of pivotally mounted arms providedwith .op-
