Scotland Application July 20, 1943, Serial No. 495,449

In Great Britain May 29, 1942 1 Claim.

This invention relates to power driven wringers and has for an object to provide a construction permitting the mounting of the wringer proper on a cabinet in such wise that, when out of use, it may be readily swung into pendant position within the cabinet.

It is common practice to drive a power wringer of the cabinet type by means of a horizontally disposed motor connected through gearing, e. g., worm gearing, with an upright shaft operatively connectible at its upper end, through the medium of a reversing gear, with a horizontal shaft carrying or coupled to the positively driven roller of the wringer.

In the wringer according to the invention, in order to render practicable the swinging movement of the wringer into a cabinet of limited dimensions, the drive has been modified in that in effect the vertical shaft has been broken into upper and lower shaft sections and the axis of swing of the wringer has been located at the point of break within the cabinet.

A construction according to the invention is illustrated in the accompanying drawing in which Fig. 1 is a side elevation part section and Fig. 2 a fragmentary detail view.

Referring to the drawing, l denotes a cabinet and II denotes a wringer which is so mounted on the cabinet ID that, when the wringer is not in use, it may be accommodated in pendant position within the cabinet, as shown in dotte lines in Fig. 1.

The wringer is mounted on a platform l2which is swingable about a horizontal axis presented by the shaft I3.

The wringer is adapted to be driven from an electric motor 14 located within the base of the cabinet [0 and arranged to drive, through a reduction gear unit [5, an upright shaft including parallel offset shaft sections l6, l6 which, in the vicinity of the shaft I3, are associated with reversing gearing. 'As shown, the lower shaft section l6 terminates at its upper end in the driving bevel pinion I! of an assembly of five bevel gear pinions of which three I8, I9 and 20, respectively, are arranged for rotation on the horizontal shaft I3 constituting the axis of swing of the wringer II, and of which the remaining pinion 2 i is secured on the lower end of the upper shaft section Iii and swings with said upper shaft section around the axis of the shaft l3. An axially movable dog clutch member 22 interposed between the two pinions l8, I9 is controllable by a handle 23 to afford forward and reverse drives and to give a neutral setting. The

I upper part of the shaft section lfi is accommodated within a gear case 24 fixed to the wringer frame and carries at its upper end a bevel gear pinion 25 meshingwith a bevel gear pinion 26 on the horizontal shaft 2! driving the positively driven roller of the wringer.

As will be understood, when the wringer H is lowered into the cabinet I0, the shaft section it swings therewith, the forward and reverse driving gear assembly |'l-22 permitting this swinging movement of the shaft section l6 What is claimed is:

In a power wringer of the cabinet type having a positively driven roller, the combination of a drive shaft. including upper and lower parallel offset shaft sections, a roller driving gear at the upper end of the upper shaft section, a bevel gear at the lower end of the upper shaft section,-a bevel. gear at the upper end of the lower shaft section, a horizontal shaft within the cabinet, three bevel pinions on said horizontal shaft, one of said pinions meshing with the bevel gear at the upper end of said lower shaft section, and a manually operable clutch device for coupling selectively either of the two remaining pinions or neither with the horizontal shaft.
