This priseA a suitable heavy standard 10 on Which causes the abrasives to drag over the inner is journaled a horizontal shaft 11, this shaft surface of the container, and, with the aid being driven by suitable means `as for exof the solvents, to loosen and remove from ample agear train 12 connected toa motor 8O `the Walls of the container the paint or other shaft 13.

0 one direction only, s o that the end for end shown in Figures 2 and 6 it may,V comprise 100 a central portion 20 having a number of arms 21 extending radially outward therefrom, three such arms being illustrated.
A drum or barrel to be cleaned may be set upon the platform or base 16 and clamped thereon as by a number of rods 22 each of which may be secured to the base 16 atone end, and to a platform 23 at the other end, as shown in Figure 1. Each tie rod 22 may be provided with a head 24 at one end and may be hinged as at 25 at the other end, a turnbuckle 26 being employed to draw the platforms 16 and 23 together to clamp a drum or barrel between them.y The periphery of the platform 16 may be suitably notched as at 27 to receive the shanks of the tie rods 22 adjacent to their heads 24 and thus to facilitate the adjustment of the clamping means to the platform 16.
A modified form of clamping member is illustrated in Figure 3. In the form therein shown, the end of the tie rod 22 remote from the head 24 is provided with a suitable hook 28 adapted to catch on the chime of a drum or barrel as shown. This form of clamping device eliminates the platform 23. The axis of rotation of the platform 16 and of a drum or barrel mounted thereon is preferably in a plane perpendicular to the axis of the shaft 11. Thus it is obvious that rotation of the shaft 11 will result in an end for end tumbling motion on the part of the drum or barrel. A chain or other abrasive object within the barrel will thus slide from one end to the other, across the head of the drum, and then back to the opposite end of the drum.
To secure a scouring Contact with all of the inner surface of the drum it is desirable to rotate the drum on its own axis while it is being tumbled in end for end motion. If the distribution of the weight of the platform and drum about the axis of rotation of the platform is unsymmetrical, when this axis reaches a substantially horizontal position in its revolution about the shaft 11, the lack of symmetry or balance of the base and drum will cause the drum to rotate on its axis as the heavy side is pulled downwardly by gravity. This lack of symmetry may be brought about in a variety of ways such as eccentric mounting of the base 16 on its axle 17, or eccentric mounting of the drum on the base 16. As shown, a suitable weight may be attached to or formed with the base 16 to throw it out of balance. As shown in Figure 6, this weight may comprise a sector 29 which may be formed at some point on the periphery of the center portion 20 of the base and may be reinforced by anarcuate member 30 which extends between two of the arms 21, its weight also acting to unbalance the platform. If the weight'29 is arranged on4 one side or the other of the plane'in which the axis 17 swings, when this axis approaches a horizontal position the weight 29 will tend to fall. Its momentum will carry it beyond center after the manner of the swing of a pendulum. To ensure continuous rotation in a'single direction, the central portion 2O of the base may be hollowed out with a ratchet 81 on its inner wall. For cooperating with this ratchet a pair of suitable pawls 32 may be provided, these pawls being adapted to slide in slots 33 arranged in the radial bearing member 18 of the arm 15. As shown, these pawls are so arranged that when the axle 17 approaches a horizontal position, one or the other will be pulled by gravitational traction into engagement with the teeth of the ratchet 31. Thus the rotation of the drum in a single direction is maintained, since the weight 29 having once swung beyond center, cannot swing back again during the same half revolution of the shaft 11. As the base and drum are revolved over toward the opposite horizontal position of the axle 17, gravity again acts on the weight 29 to continue the otation of the base and drum carried there- Tclaim: Y 1.
