Title: Improvements in apparatus for cleaning drinking vessels and the like
IPC: A47L15/00
Filed: 1934-08-15
Abstract: 418,736. Cleaning drinking-vessels &c. HERZIG, J., 81, Heinrichstrasse, Fulda, Germany. Aug. 15, 1934, No. 23557. Convention date, Aug. 16, 1933. [Class 138 (i).] Apparatus for cleaning drinking-vessels and like vessels comprises brushes mounted on a telescopic support, to the tubular members of which the brushes are connected so that they can swing outwardly about axes parallel to the central longitudinal axis of the support and can also rock about axes transversely of the support. In the construction shown, a hollow column rotatably mounted about a vertical axis carries a rotor d adapted to drive three brushes h, h<1>, h<2> mounted respectively on tubes i, i<1>, i<2>. The tube i<1> fits slidably into the tube i, and the tube i<2> fits slidably into the tube i<1>. The tubes are connected with each other by studs engaging vertical slots. Water is supplied to the rotor d through a pipe fitted with a valve b which also controls the flow of water through a perforated tube f to the brushes. Each of the brushes is mounted to swing outwardly about a vertical axis, as shown in Fig. 4, and the vertical pivot can rock about a horizontal axis as shown in Fig. 5, to adapt the brush to a tapered vessel. A circular plate k connected to the rotor d carries two brushes for cleaning the outside of the vessel, each brush being pivotally mounted and weighted so as to be pressed against the vessel by centrifugal force when the brushes are rotated. The plate k supports a resilient mat n adapted to receive the edge of the drinking vessel. Pressure on the mat causes the valve b to open against spring action and allow liquid to drive the rotor d and to pass through the tube f. The pressure of the water causes the extension of the brushes i, i<1>, i<2> which are normally in their lowermost positions.
