WASHING PLUNGER.

Application filed September 2, 1924. Serial No. 735,476.

To all whom may concern:

Be it known that I, SIDNEY OSWALD U LLA- THORNE VEAL, a British subject, of 16 Moorland Road, Forest Lane, Harrogate, in. the county of York, England, have invented certain new and useful Improvements in or Relating to ashing Plungersl (for which I have filed application in Great Britain, April 12, 1923, Number 9930), of which the following is aspecification.

This invention relates to washing plungers of the cone or hell type wherein the surface or surfaces are roughened to afford a more eflicient friction inducing effect on the water and clothes with less liability to injure or impair the latter. It has previously been proposed to form dollies with ribbed, corrugated or rpughened surfaces; also to construct them with rela tively movable spring-controlled pistons or plungers. It has also been proposed to provide a plunger having an under-surface formed with ribs or other projections.

According to the present invention the essential feature consists only in the pro vision of means for producing aslightfrictional effect by forming the base or unden surface with a slightly roughened or rubhing surface formed by milling, corrugating, or pressing or as a brush. The plunger may be either solid or hollow, and may as previously proposed comprise members fitting one within the other and so mounted on the handle as to have relative movement to each other when the plunger is in use.

In order that the invention may be clear- 1y understood and readily carried into effeet the same will now be more fully described with reference to the accompanying drawings in which Figure 1 is a fragmental view of a plunger of domed formation with its lower surface or edge corrugated.

Figures 1 and 1 are inverted plan views drawn to smaller scale of the solid and hollow forms respectively of the plunger shown in Figure 1.

Figure 2 is a similar view to Figure 1 showing the lower edge or surface roughened or serrated.

Figures 2 and 2-" are similar views to Figures 1 and 1 of the plunger shown in Figure 2.

Figure 3 is a vertical section showing one member of the plunger movable relatively to the outer casing of the plunger.

Figure 4 is a similar View to Figure 3 showing the movable portion adapted to fall by gravity when in its raised position.

Figure 5 is a plan of Figure 4.

Figure 6 shows in vertical section amodification with the handle threaded for engagement with the plunger.

Referring to Figures 1 and 2. of the drawings, the plunger 12 is formed with its lower edge or base 1.0 corrugated, roughened or serrated for producing the required friction and agitation of the water and clothes when in use. As shown in Figures 3, 4 and 6 the roughened under surface may take the form of a brush 1'? either fixed as in Figures 3 and 6 or movable as in Figure 4. In the form, illustrated in Figure 3, springs 13 are interposed between the piston 11 and the brush 17 or member carrying the roughened surface. The bandle 16 may be secured to the plunger 12, see Figures 1, 2, 4i. and 5, or to the piston 11, see Figure As indicated in Figure l: the brush 17 may be recessed at 18 for slidably engaging with the plunger 12 at 18 said friction brush 17 being adapted to fall by gravity when the handle 16 carrying the fixed portion 12 is in its raised position. At their lower ends the guides 18 are provided with suitable stops 20 for limiting the downward movement of the piston. Holes 19 are provided in the plunger 12 and the friction brush 17 to allow the water to circulate. In the constructions shown in Figures 4 and 5, it will be clear that the brush 1'? acts as a piston. By reason of its sliding movement a suction effeet will be created. The handle is preferably of T-shape at its upper end, as shown in Figure 1, to facilitate manipulation, and may be screw threaded at its lower extremity .to engage With and carry the friction brush 17, see Figure 6, instead of being movable relative thereto.

I claim A washing plunger comprising a casing provided. with an open bottom, a piston member in said casing freely slidable t0- ward and from the open bottom thereof, guides on said casing for said member, said member and the casing above said member having openings therethrough for the ingress and egress of Water, and brush-like clothes engaging means on said member.
