SPECIFICATION forming part of Letters Patent N 0. 752,160, dated February 16, 1904. Application filed November 27, 1903. Serial No. 182,717. (No model.)
To ail whom it may concern.-
Be it known that I, IVALTER I'IEN'RY HART, a citizen of the United States, residing at New Britain, in the county of Hartford, State of 5 Connecticut, have invented certain new and useful Improvements in To mbling-Barrels, of which the following is a full, clear, and exact description.
My invention relates to tumbling-barrels, and my main object is to provide certain improved features of construction whereby said barrels are made very durable.
In the drawings, Figure'l is an end. elevation of a tumblingbarrel with a portion broken away and shown in section. Fig. 2 is a fragmentary sectional view.
A A are staves ordinarily arranged edge to.
edge at an angle to each other and. forming the side of the barrel.
B B are plates which may correspond in number and arrangement to the s .avcs and which in the special form shown are arranged inside of said stares and secured thereto in any well -known manner fo example, by
z 5 means of headed rivets I) l).
E is the barrel-head. The platesB B serve to take the wear of the articles which are tumbled within the barrel and cover and protect the staves A A and The plates B B are arranged so that one edge of each plate overlaps and bears'upon the edge of an adjacent plate. Hence each plate will act as a support for the overlapping edge of an adjacent plate.
The overlapping edges are indicated at Z 6. It will be seenthat said overlapping edges are arranged in the same direction. IrVith this arrangement the barrel may be rotated in such a direction as to cause the articles within the barrel to slide freely over each overlapped edge and onto the next plate, rather than to engage end on against the edges of said plates. In the arrangement shown in Fig. l the barrel should be rotated clockwise. Aftera time the overlapped edges 'of the plates would be worn down by the rubbing action of the tumbling articles, thus forming a substantially continuous bearingsurface. (See Fig. 2..) It will be observed that by this arrangement the plates reinforce one anotherand that there is no imperfect or open seam left between the plates B B to be filled or clogged with line particles of metal, the presence of which would tend to dislodge and unseat the edges or" the platcsand render the barrel useless until repaired.
' By my invention the life ot the barrel is substantially prolonged. .The overlapping edges of the plates B B render the harrcl much more durable and effective than would he the case were the plates B B arranged edge to edge. In such aconstruction a seam is alwaysexposcd to the action of the tumbling articles. Even assuming the plates were at the outset accurately and carefully fitted edge to edge, the warping of the plates during use would cause the edges to draw away from each other, and thus leave an opening for the accumulation of particles or metal which would tend to further unseat and dislodge said plates. Not only is an imperfect joint between the plates disastrous for the above reasons, but it also affords a space for the tumbling articles to lodge in, which as they are carried around would bend or break other loose articles within the barrel. In barrels of this type where it is necessary to line the interior it is most important that the edges of the plates should be effectively joined, for if the staves of the barrel are exposed the same wear out very rapidly, rendering the entire structure unfit in a comparatively short time. By my invention the sheet-metal lining may be much more economically applied than if the liningplates were arranged edge to edge and not overlapped, because it obviates the necessity of beveling the edges of the plates necessary in forming a perfect buttrjoint.
It should be understood that the general construction of the barrel is immaterial, iny plates secured thereto, one edge of each plate invention relating more particularly to the overlapping and resting upon the surface of means for lining the interior of the same. the next adjacent plate, said plates covering What 1 claim the joints between said stavesj 5 1.
