APPLICATION FILED $21 115, 1914.

r0 1 9 1 6 1 F d 6 t H m a P JEWHI RENISCH, OF, CHICAGO, ILLINQIS.



To all whom it may concern Be it known that I, EMIL RnNIsoH, a citizen-of the United States,.andresident of Chicago, county of" Cook, and State of Illinois, haveinvented certain. new and useful Improvements in l/Vashing-Machines, of which the following is a: specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to Washing machines of that type in which a tumbling barrel is provided and the invention has more particular reference to those machines which are used for washing small castings, punchings and the like to remove grease or otherwise prepare the same for subsequent treat.- ment, as for example,- electro-plating;

The object of the invention is to provide an improved mounting for the tumbling barrel, whereby the same may be rotatably supported in any one of a plurality of. different positions.

When a tumbling-barrel is used for washing a quantity of small castings, punchings or the like by immersion of the barrel in a liquid, it isimportant that the barrel be rotated upon: its. withdrawal from the liquid to insure a complete drainage of the cleansing medium. This is for the reason that the contents of the barrel is of'such a character as to provide pockets for retaining the liquid and from which the liquid will be discharged only upon rotation of the barrel. A feature of the invention accordingly provides for rotation of the barrel when supported in an elevated position for drainage.

The invention also contemplates provision for raising the barrel over a side Wall of the tank for emptying the contents of the barrel into a suitable receptacle placed upon the floor.

In the accompanying drawings, Figure 1 is a side elevation showing a washing machine embodying the features of improvement provided by, the invention, some of the parts being shown in cross section, and a different position of the movable parts being indicated by dotted lines; Fig. 2 is a detail perspective view showing a clutch arm which may be used for supporting the 7 tumbling barrel in one position, and Fig. 3 is a detail plan view showing a form of receiving table which may be employed in connection with the machine.

In carrying out the invention a tank 10,

is provided for. containing the cleansing medium, as gasolene.- This tank is desirably supported in an. elevated position, as in a frame generally designated 11 and having legs 12 and 13. Preferably the frame 11 is extended, at one-side of the tank 10 and has an additional upright 14 for supporting the outerend of an inclined receiving table 15. The inner end of this table is conveniently supported by resting the same upon the adjacent side wall of the tank.

The tumbling barrel is generally designated 16. It is preferably made in the form of an octagonal drum having closed ends, as 17 and foraminous side wall panels, as 18, 19. To facilitate the filling of the barrel and the discharge of its contents, one of the side wall panels, as 19, is made openable, asby theuse of a hinge 20 for connecting the same-with the adjacent panel 18, along one edge. Trunnions, as 21, are fixed upon the ends, as 17, of the barrel and the rim of the tank 1.0 is notched, as at 22, to receive these trunnions in one position of the drum. A crank 23-applied to one of the trunnions serves for rotating the barrel.

The tumbling barrel 16 is conveniently filled from the receiving table 15 when the barrel has been lowered to the position in which its trunnions, as 21, are engaged with the notches, as 22. For this purpose the hinged panel 19 is opened and a chute 24, containing the articles to be cleansed, is placed upon the receiving table 15 and slidingly advanced thereon to a position in which one end of the chute enters the opening provided by raising the panel 19. The contents of the chute 24 are then easily discharged into the barrel. If desired, angle plates, as 25, 26, may be applied to the receiving table 15 to serve as guides for the chute 24. Preferably these angle plates are positioned upon the receiving table to readily receive the chute 24 between them at the higher end of the table, and they converge toward the lower end of the table for guiding the chute into the open side of the barrel. It will be understood that when the barrel 16 is supported in the receiving position with the trunnions, as 21, engaged with the notches, as 22, the barrel is suificiently immersed in the contents of the tank 10, for the washing operation and that this operation may now be accomplished by merely closing the panel 19 and operating the crank 23.

wall of the tank 10 and into a receptacle (not shown), placed upon the floor. Bell crank levers 2 located at each end of the barrel, but only one of which is shown, serve vfor elevating the tumblin barrel to the positions just described. T ese bell crank levers are fulcrumed in alinement upon the rim of the tank 10, as at 28. A rod 29 connects the two bell crank levers 27 ad'acent their outer ends, formin a rigid rame. The end of each bell cran lever 27 remote from the rod 29, rotatably receives the corresponding trunnion, as 21. A supporting leg, 30, pivotally connected with each bell crank lever 27, adjacent the point of attachment thereto, of the rod 29, serves to engage the floor and support the tumbling barrel 16 when the same has been raised to the discharging position.

A clutch bar 31, pivotally mounted upon 'the end wall of the tank 10, may be employed' to cooperate with the bell crank lever 27 for supporting the barrel 16 in the position indicated by full lines in Fig. 1. This bar is notched intermediate its ends, as at 32, Fig. 2, to receive the corresponding trunnion 21. If desired, it may be continued beyond the notch to a position in which it is conveniently accessible to an operator standing at the side of the tank on which the bell crank levers, as 27, are located. Preferably a duplicate, (not shown) of the clutch bar 31, will be provided at the end of the barrel the notch 32 of the clutch 16 remote from the bar 31. In this event the free ends of the two clutch bars are connected by a rod 33 which extends along side of the barrel 16 and serves as a convenient means for manipulatin both bars. When the tumbling barrel 16 1s supported in position with its trunnion, as 21 engaged with bar 31, it will drain into the chamber of the tank 10 and this draina e may be facilitated by the use of the cran 23 to rotate the barrel. Any liquid which would otherwise be retained by pockets formed in or among the contents of the barrel is thus readily ischarged.

I claim as my invention,

In a washing machine, in combination, a rectangular tank, a bell crank lever pivotally mounted upon the tank to swing in a lane which is parallel to one of the side wa ls of the tank, a tumbling barrel having foraminous walls, a trunnion for the tumbling barrel journaled in one arm of the lever and engageable with the said side wall of the tank for supporting the tumbling barrel in one position, a clutch arm pivotally mounted upon the tank and engageable with the trunnion to support the tumbling barrel in another position in which-the tumbling barrel is located above the tank and a leg pivotally connected with the other arm of the bell cranklever and engageable with the floor at one side of the tank for supporting the tumbling barrel in a third position in which the tumbling barrel is located beyond a side wall of the tank from the tank chamber.
