WASHING MACHINE Filed April 5, 1945 IN V EN TOR.

47- TOEA/EY Patented July 2, 1946 UNITED STATES PATENT OFFICE 1 Claim.

This application relates to apparatus for tumbling and washing steel barrels or drums and aims particularly to provide an improved tumbling and washing machine. The machine tumbles a barrel in a tank full of washing solution, and the barrel, by such tumbling, is washed inside and outside, and the machine hereof is an improvement over that of my prior Patent 2,116, 753 of May 10, 1938.

For an understanding of my tumbler and washer, reference may be had to the appended drawing. In the drawing,

Figures 1, 2 and 3 are respectively front, top, and end views of my apparatus.

Fig. 4 is a section on line 44 of Fig. 2.

This machine shown comprises an open top tank 5, the upper part of whose front is open as indicated. The tank contains washing solution in which the barrel is tumbled and thereby washed, internally and externally.

The end walls 6 and I of the tank are provided with bearings 8 and 9 for axially aligned stub-shafts III and II, the inner ends of the shafts being connected to, and supporting a cradle or cage I2 for receiving therein a barrel or drum to be washed and tumbled.

The stub-shaft III is welded to the end of the cage I2. To the end of the stub-shaft I I is welded a lid I3 to which the cage I2 may be bolted, as by bolts l4, so that the joint between the cage and the stub-shaft II is separable.

Struts I welded to the stub-shafts and to the end of the cage 12 and to the lid I3 are provided for reinforcement.

The stub-shaft I I i formed to project through the end-wall I of the tank a considerable distance and to the projecting portion is slidably keyed a gear 2| meshing with a pinion 22 of a speed reducing drive means 23, coupled to a motor 24 mounted on a platform 25. The platform is provided with brackets 26 supporting a cross bar 21 which mounts a bearing 28 providing a second bearing or journal for the shaft I I. Between the two bearings 9 and 28 is located the gear 2I.

2 The entire driving means, comprising the gear 2|, the pinion 22, the speed reducer 23, the motor 24, and the bearing 28, is enclosed by a cover 25 which is removable to expose the drive means for lubrication, inspection, and repair. The drive means is so positioned relative to the tank that it is completely sealed from the interior of the tank.

For disassembly purposes, it is possible to loosen the bolts I4, and remove the cage I2 with stubshaft I0, without disassembling the drive means. When the bolts I 4 are loosened, and the cage, with stub shaft II), lifted out, the stub-shaft II with the lid I 3 may be moved within the tank away from the end wall I so as to separate the stub-shaft from the gear 2I keyed thereto, whereupon the drive members are separable and available for repair or replacement.

Now having described the drum tumbling and washing apparatus herein disclosed, reference will be had to the claim which follows for a determination of the invention.

I claim:

A barrel washing and tumbling machine comprising a tank having end walls, each provided with a shaft bearing, two alined stub shafts mounted in said bearings, a barrel cradle between the stub shafts, and each stub shaft having a connection securing it to the cradle, one of said connections being separable, one of the stub shafts projecting through one of the tank end Walls, means secured to the tank for supporting a shaft bearing at a point remote from the last named tank-end, a bearing on said means, the last named stub shaft being journalled at spaced points in said last-named bearing and in the bearing of the adjacent tank end, a gear on said last-named stub shaft between its two bearings, a motor and a speed reducer drive means mounted on a platform below the stub shaft and gear, and a pinion on the drive means meshing with said gear.

ADOLPI-I M. DINETZ.
