Specification of Letters Fatent.

'l i; all whom it may conce/m p Be it known that '1., Jenn W. HEAPHY, o Rochester, in vthe ,county iof Monroe and State of New York, have d ted certain ner.' and useful lmprorenients in Tumblingarrcls; and l do hereby declare the following to be a full, clear, and enact description being had to the ue forming e pei-rt of to the re ferenceumerels marked thereon.

Mv invention has for its object to proyide novel form of tumbling-barrel, such as my be employed for the purpose of polishu .ng or cleaning or otherwise treating small articles yby an' agitating process, one of the purposes ot the invention being to provide :i construction that permits the more ready feeding' or discharging of the articles to or .from the machine.

A further object of the improvements is to afford an arrangement that will eil'ect a, quicker and more thorough agitation of the articles, the structure by which this result is accomplished being simple and ecouomicul to manufacture.

To these and other ends the invention consists in certain improvements land,combiioaY 'tions of parts, all as will be hereine'fter more fully described, the novel tentures being pointed out in the claims et the end of the specification.

Similar reference numerals throughout the several viev 's indicate the same parts.

The inrention. is susceptible of various applications, a more common use being in the polishing or abrading of smell articles of metal or other material and in thc pres ent embodiment, which shows an instance of a member carrying out the invention, the tumbler comprises a body A which is substantially cylindrical and is provided with the ends or heads B which extend beyond the periphery of 4the body and are connected by brace rods C. To the heads E are secured journals mounted in bearings, one of said jouwe-ls being provided with a, tilted ES FATE Patented Mar. 2i. 1.916.

by either one of the. oppositely moving belts being controlled by Shifters F. i

The body of the tumbler is preferablyv formed of Celluloid although itmay bc constructed of any other desirable material from a sheet that is bent u ,on itself circulerly to the desired size o cylinder. The opposite ends of the sheet from which the tumbler is formed are attached together along the lines G and H, one end being extended to define a tapering portion which overlaps the under ,layer of the body as shown in Figs. 1 and 2. The overlapping portions are offset or embossed inwardly and outwardly as designated at I and J thereby affording :i tapering opening K into which the articles can readily be fed and fioni\wliich their discharge is easily eli'eeted. The articles are led to thetumble'r while il is in the position shown in Fig. 2, and are thereafter gitated and treated, by rotation of the cylinder in a clock-wise .direction To discharge the articles from the cylinder, its direction of movement is reversed so that as the opening K moves in an anti-clockwise direction, the contents are quickly removed, such removal being assisted by the tapering character of the discharging opening.

lt is quite desirable that the article undergoing treatment bo agitated to a maximum degree und to this end l, may employ means for causing an additional movement of the. articles toward and troni the ends of the cylinder and fordropping them from the top to the bottom of the cylinder at intervals. This may be accomplished by providing the body of the tumbler with a pluality or inwardly projecting bullies or ribs L which are preferably formed by embossing, and extend in curved lines from points between the center and ends of the cylinder to near the center of the cylinder, as shown in Fig. 'l. The result of this construction is that as the tumbler rotates, the curved ii-ailles engage the articles and eflect movenient of the latter successively toward the center line of the cylinder. Certain of the balles li terminate. at a point adjacent to a pocket )rejecting offset body of the cylinder. moved inwardly, array from the ends of the, cylinder oy the bullies L, arc caught up by the. mollet M- and carried upwardly by the latter until it is nearly at the limit of its upward movement, whereupon they are dropped to the bottom and the operation is repeated.

' The construction described affords a novel and extremely etlicient arrangement for the purposes set forth, the tumbler being of simple and comparatively economical construction While at the saine time, quite strong, and rigid enough for the purposes intended, and it is to be understood that the present application is intended to cover any departures from the specific construction described that may come within the terms of the appended claims.

I claim as my invention:

1. A tumbling barrel comprising a substantially cylindrical body formed from an integral sheet of material which embodies a tapering overlapping portion, the part of the body underlying said overlapping portion being offset from the periphery so as to form a tapering charging and discharging opening. y

2. A tumbling barrel comprising a substantially cylindrical body and a tapering overlapping portion which is offset from the periphery of the body so as to form a taperlng charging and -discharging opening.

3. A tumbling barrel comprising a sub stantially cylindrical body having a plurality of inwardly projecting baflles which entend in curved lines toward the center of Y the center and the ends the body from points between the center and the ends of the body, the inner ends of the bafles terminating adjacent to a recess or pocket formed by an outwardly extending offset portion on the body.

4. A tumbling barrel comprising a substantially cylindrical body and overlapping portions which are offset in opposite directions from the periphery of the body affording a charging and discharging opening, the body being provided with a recess or pocket approximately opposite said charging and discharging opening formed by an outwardly extending offset portion in the body, and a plurality of inwardly projecting battles which extend in curved lilies toward the center of the body from points between off-the body, the inner ends of the battles terminating adjacent to said recess or pocket.

5. A tumbling barrel comprising a substantially cylindrical body embodying a tapering portion offset from the periphery of the body and overlapping a portion of the body which is offset in the opposite direction from the periphery of the body so as to form a tapering charging and discharging opening.
