is supported by bearings 3? mounted upon a bracket 38.

The apparatus is particularly intended for use with a standard laundry ironer (not shown) and such machine ordinarily is provided with a rotating feeding table as indicated by the numeral 3%. As will become apparent, the clothes are discharged upon this table after they have been sultably loosened or shaken out.

The operation of the apparatus is as follows:

The tumbler 25 normally occupies the position shown in solid lines in Figures 1 and 4. The motor 32 preferably operates constantly, and the relative sizes of the pulley 33 and the cylindrical portion of the tumbler are such as to provide the desired speed reduction in the rotation of the Clothes are fed into the opening 29 as the tumbler rotates, and the axis of the supporting spindles or stub-shafts l9 preferably is in the vertical plane of the center of gravity of the tumbler and the parts connected thereto whereby the tumbler operates when either loaded or unloaded without any tendency to rotate about the axis of the spindles 59.

The rotation of the tumbler 27 about the axis of the shaft 39 continues until the clothes have been suitably loosened. In this connection it will be noted that the rotation .of the tumbler continually elevates and then drops the clothes to tend to loosen them substantially in the same manner that they are conventionally loosened by shaking with the hands. When the loosening operation has been sufiiciently completed, it merely is necessary for the operator to rotate one of the wheels 29, and this operation may be accomplished with little physical effort in view of the placing of the spindles l 9 with respect to the tumbler. The rotation of one of the wheels 20 in a counterclockwise direction as viewed in Figures 1 and 4 causes the tumbler to be rotated about the axis of the spindles I9, and the action referred to also rolls the gears 88 along the racks H. The gear and rack arrangements at opposite sides of the apparatus are identical, and accordingly the axis of rotation of the spindles l9 partakes of no angular change.

The rotation of one of the wheels 28 is continued until the tumbler assumes substantially the dotted line positions shown in Figures 1 and 4 at which point the tumbler is substantially inverted and the opening 29 is arranged substantially vertically beneath the uppermost portions of the tumbler. During the entire operation referred to, the tumbler is rotated by the motor 32, and this rotation, when the tumbler reaches discharging position, continues to elevate the clothes after which they progressively drop through the opening 29 in a loosened condition upon the table 39. As soon as the tumbler is completely emptied one of the wheels 20 is again rotated in the op posite direction to restore the parts to normal position ready to be loaded with twisted clothing. The operators of the ironing machines are thus supplied with damp loosened articles upon the table 39, and these articles are picked up and fed into the ironers in the usual manner without the necessity of having to loosen or shake out the Thus the manual labor ordinarily involved in the shaking out of the articles is completely avoided, the tumbler performing this work in a quick efiicient manner.

The use of the apparatus has further advantages for the reason that it permits the feeding of the clothes to the apparatus from one side thereof while the clothes are discharged from the aooa'zee other side or" the apparatus to the receiving table. Thus the operators who feed the clothing into the tumblerdo not interfere in any way with the operators who pick up the articles from the table 39 and feed them to the ironing machine.

Wheels 25 preferably are provided at both sides .of the apparatus merely as a matter of convenience, but it will be apparent that only one wheel need be employed. Moreover, a lever or similar operating element may be employed in place of the wheel. It further will be obvious that the length of the racks H and the diameters of the gears it may be varied as desired according to the distance through which it is desired to move the tumbler bodily from its loading to its unloading position.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

I claim:

1. Apparatus of the character described comprising a supporting frame, a substantially cylindrical tumbler having its axis normally arranged substantially horizontally, said tumbler having an opening in one end, a shaft connected to the other end of said tumbler and journaled in said frame, a motor supported by said frame and having a pulley arranged with its axis parallel to the axis of said tumbler, and an endless belt passing around said pulley and around said tumbler, means for supporting said frame for rotation about a horizontal axis, and means for eiiecting bodily movement of said frame at right angles to said horizontal axis during rotation of the frame thereabout.

2. Apparatus of the character described comprising a supporting frame, a substantially cylindrical tumbler having its axis normally arranged substantially horizontally, said tumbler having an opening in one end, a shaft connected to the other end of said tumbler and journaled in said frame, a motor supported by said frame and having a pulley arranged with its axis parallel to the axis of said tumbler, and an endless belt passing around said pulley and around said tumbler, and means for supporting said frame for simultaneous rotation about a horizontal axis and for bodily movement substantially horizontally at right 21.1%

gles to such axis.

3. Apparatus of the character described comprising a normally horizontal substantially U- shaped frame, a substantially cylindrical shakeout tumbler having an opening in one end and having its axis normally substantially horizontal, a shaft connected to said tumbler coaxially thereof and rotatably connected to said frame, a pair of horizontal stationary racks arranged adjacent opposite sides of said frame, and coaxial gears carried by said frame and meshing with said racks.

4. Apparatus of the character described comprising a supporting frame, a substantially cylindrical shake-out tumbler connected to said frame for rotation about its axis, a motor carried by said frame and having a pulley arranged with its axis parallel to the axis of said tumbler, an endless belt passing around said pulley and said tumbler, a pair of supporting racks, and a pair of coaxial gears carried by said frame and meshing with said racks.

5. Apparatus of the character described comprising a normally horizontal substantially U- shaped frame, a substantially cylindrical shakeout tumbler having its axis normally substantially horizontal, a shaft connected to said tumbler coaxially thereof and rotatably connected to said frame, a motor rigidly connected to said frame and provided with a pulley arranged with its axis parallel to the axis of said tumbler, an endless belt passing around said pulley and around said tumbler, a pair of racks arranged adjacent opposite sides of said frame, and coaxial gears carried by said frame and meshing with said racks.
