1 Claim.

My invention pertains to wash wringers, and has for one of its objects to provide a simple and effective strippervroll, preferably in the form of a brush, and associated with the upper squeeze roll of a wringer, whereby the material fed through the machine is stripped from the surface of the upper roll.

Another object of my invention is to provide a pair of brushes suitably geared to the wringer rolls, whereby the material fed throu-gh the said wringer rolls is stripped from the surface of the upper roll, irrespective of the direction the material may be fed through the wringer rolls.

Another object of my invention is to provide cylindrical stripper brushes of cheap construction formed from coiled wire strands, and having bristles coiled therebetween, these brushesbeing capable of ready insertion into journal sockets associated with the Wringer, and when so desired they are in gear connection with the wringer roll.

With the above and other minor objects in view, the invention consists in certain peculiarities of construction, as fully set forth hereinafter with reference to the accompanying drawing and subsequently claimed.

In the drawing:-

Figure 1 represents a sectional elevation of a wash-wringer, having attached thereto a pair of stripper brushes embodying the features of my invention.

Figure 2 is a side elevation of the same, with parts broken away and in section to more clearly illustrate structural features particularly pertaining to the drive mechanism for the brushes.

'Figure 3 is an end view of the wringer with parts broken away and in section to more clearly illustrate the structural features,said end view showing one method of gearing whereby the brushes are positively driven from the lower roll.

Referring by characters to the drawing, I represents any standard wringer frame provided with upper and lower wringer rolls 2--2, respectively, these rolls being in positive gear connection, as indicated at 3, it being understood that these gears are provided with the usual housing. The shaft 4 of the lower roll extends into the usual gear housing 5, supported by a column 6, which carries a motor-driven shaft for'imparting power to the shaft 4 through nested gears contained in the housing 5 (not shown). The housing 5 is provided with an additional housing 5', which is secured to the wringer frame, and which encases a gear train for driving stripper brushes 1 1.

In this exemplification of my invention the gear train comprises a proportionately large gear 8, which is fastened to the roller shaft 4,l and meshes with smaller toothed gears 9-9', which toothed gears are carried by stud shafts I0 journalled in bearings formed in the housing 6. These stud shafts carry keyed sockets II for'the reception of the end trunnions I2 of the brushes. These end trunnions carry pins I2 adapted to enter the keyed slots of the sockets II, whereby a quick coupling is effected when the brush is inserted in its bearings.

The opposite end journal I3 of the brush is fitted in a bearing I4 carried by the wringer frame, and this bearing has mounted therein a spring I5 and follower, whereby the end journal can be adjusted in its bearing, and the opposite end of the brush is then locked into the coupling II.

From the foregoing description it will be observed that the cylindrical stripper brushes can readily be adjusted to the wringer, and when so adjusted they are positively driven through the train of gears previously described.

As best shown in Figure 1 of the drawing, the wringer rolls are rotated to feed material from right to left in the direction indicated by the dotted arrows A. As the material is fed through the wringers, the iirst brush'l, due to its direction of rotation, will tend to aid in feeding the material between the wringer rolls, and should said material, as it is discharged from the wringer, adhere to the outer face of the upper roll, obviously the cylinder brush 1', travelling in the direction as indicated by the arrow, will strip said material from the upper roll, and cause it to feed smoothly to the discharge point.

Obviously, if the Wringer is reversed, the feed of the material would run through the wringer rolls from right to left, in which case the brush 'I' would aid in feeding the material between the wringer rolls, and the brush'l would then serve to strip the material from the surface of the upper roll. It is understood that the brushes 'I and l are preferably driven at higher peripheral speed than the speed of the upper wringer roll.

While I have shown and described my invention minutely as to details, it is obvious that I may vary said details as come within the scope of the claim:-

In a wash wringer, the combination with the upper and lower wringer rolls thereof having an operative connection at one end, of a stripper device for the upper roll including rotatable stripper brushes engaging the opposite sides of the upper roll, a relatively large gear rotatable with the lower roll and having a greater diameter than the upper and lower rolls, and pinions rotatable with the stripping brushes meshing with the opposite sides of the relatively large gear above the lower roll.
