l 24 Claims.

The invention relates to cleaning and dusting tools, and more particularly to pneumatic suction cleaning tools of the type known commercially luider the registered trade-mark Air-Way. Such tools are adapted to be attached to the ends of pipes used in connection with either stationary or portable pneumatic cleaning machines, and

more particularly in connection with apparatus of the type illustrated in my Patent 1,533,271, dated April 14, 1925.

The present application is in the nature of an improvement on the device disclosed in my prior Patent 1,403,524, dated January 17, 1922. In common with the cleaning tool covered by this patent, the present invention relates to a suction tool, having a body composed of resilient elastic material, which body portion includes a shank having a portion thereof shaped and adapted to be connected at one end to a suitable suction pipe or nozzle, as shown in my Patent 1,533,271, and having at its other end a mouth portion which may be used directly for cleaning or dusting purposes, but which is adapted to receive a dusting or application member of suitable construction.

The cleaning tool is provided with a passageway which opens into the shank portion and which is provided with a reduced throat portion Vconnecting the mouth and the shank portions thereof. It has been found in practice that when excessive pressure is applied to the tool during use, there is a tendency for the rubber shank to collapse or bend at this reduced portion, and according to the present invention, this defect is overcome by providing a reinforcing rib or ridge extending longitudinally of the shank to compensate for the reduced portion.

Another feature of the present invention isv the shape of the rubber end of the shank which is placed over the suction tube of the cleaning apparatus. This tube or nozzle, as disclosed in my prior Patents 1,403,524 and 1,533,271, may be either round or at. According to the present invention the end of the shank which is applied to the suction tube is normally oval-shaped, and consequently ts readily over a round or fiat tube, the material of which the shank is made being sufficiently deformable for this purpose.

Another feature of the present invention is thev provision of a pocket in the mouth of the body.

member, which pocket is provided with resilient Walls or ribs which when forced apart and the application member forced therein grip the ap- Vplication member sufficiently tightly to detachably retain the same within the mouth. As to this feature the present application contains matter in common with my application Serial No. 15,529, filed March 14, 1925.

The novel form of the dusting tool constitutes another feature of the invention. Other features will appear hereinafter.

The invention will be more readily understood by reference to theV accompanying drawings and the following detailed description, setting forth a specific embodiment of the invention.

In the drawings:

Fig. 1 is a perspective View illustrating one form o-f the tool in use, the tool being applied to a round suction pipe, and the application member comprising a hollow `element. of substantially frusta-conical form to the mouth of which a soft fabric cover is applied;

Fig. 2 is a side elevation of the tool with the body and application members assembled ready for use;

Fig. 3 is a longitudinal cross-sectional view of the body member;

Fig. 4 is a transverse section on line 4 4 of Fig. 2; Y

Fig. 5 is a View looking into that end of the rubber shank ofthe tool to which the suction pipe is to be applied;

Fig. 6 is a perspective detail view of the appli cation member, shown in assembled position in Figs.. 1 and 2, the mesh cover being removed;

Fig. 7 is an axial sectional View of the same;

Fig. 8 is a perspective View of the silken netting or fabric cover which is adapted to be assembled with the application member shown in Figs. 6 and 7;

Referringparticularly to Fig. 1, A denotes a suction pipe or tube of any desired type, but preferably one of the vdetachable extension members of a cleaning apparatus such as is shown in my Patent 1,533,271, and B the hollow body portion of an application tool, which is detachably connected to the suction pipe. At the mouth of the body member an application member C is detachably applied. For the purpose of illustration the tool is shown in use for removing dus from a cushion D.

The hollow body B of the application tool is made of resilient elastic material, preferably rubber, and comprises a sha'nk portion 10, to the end 11 of whichthe suction pipe A is applied, and a mouth portion 12 connected to the shank through an intermediate throat portion 13. As shown, the axes of the shank and mouth portions are substantially at right angles to each other.

The shank 10 is preferably provided with a strengthening bead or lip 14, at the end of which the handle is applied, and as shown in Fig. 5, its end is neither round nor flat, but oval, thus permitting the shank to be readily applied to either a round or nat suction pipe. A round pipe A is shown in Fig. 1, but the same shank conforms itself equally as well to a flat tube or nozzle, such as that disclosed in my prior Patent No. 1,403,524, due to the resilience and elasticity of the material of which it is composed. The stiffening bead or lip 14 insures an air-tight t.

Since pressure must be applied to the pipe A when the tool is in use, there was a tendency in the device disclosed in mypatent for the kshank to bend or collapse. The collapsing tendency was increased by the suction within the tool. To avoid this tendency I have, according to the present embodiment of the invention, provided a strengthening rib 15, herein Shown as extending longitudinally along the upper surface of the shank, and being of greatest thickness adjacentv the throat of the tool. This rib eifectively overcomes the bending or collapsing Vtendency of the shank. n As shown, the mouth 12 of the body member the insertion of the bead or flange 20,-will r-rnly but detachably grip the bead and prevent accidentalremoval or loss of the application member.

As shown in Figs. 1, 2, 6, 7 and 8, the application member includes the hollow element 21 substantially frusto-conical in form, preferably composed of phenolic condensation product, fiber or other similar material, provided with the bead 20 at the upper portion for cooperation with the groove 18 in the body B, as above described, and provided also with a lower flaring skirt portion, preferably reinforced at intervals by suitable strengthening ribs 22. A bead 23 is formed at the lower extremity of the skirt.

A fabric mesh cover 24, shown in detail in Fig. 8, is then applied to the conical member. The cover provides a soft, exible, porous undersurface, which engages furniture or other articles being cleaned without marring the same, and permitting fine particles of dust to pass through the mesh of the fabric, while preventing passage of larger particles. Such a cover renders the tool useful in cleaning smooth surfaces, as Well as for cleaning small articles Which'might be drawn into the suction handle were it not for the fine mesh cover, which cover acts as a lter. The cover may be composedof any suitable mesh material, depending on the size particles it is de.- sired to have pass therethrough. Preferably-material of soft, silken texture is employed. The cover is readily attached to the conical member 21 by drawing the mouth of the cover over the bead 23 and detachably securing the parts together by any suitable means, as a rubber elastic band 25.

The invention has been described in detail for'y the purpose of illustration, but itwillbe apparent thatmany modincations may be resorted to without departing from the spirit of the invention.

It will be apparent that the body member'of the tool, shown in Fig. 3, may be used for cleaning purposes without the additional application member, the bead 19 serving for attachmentof a mesh fabric hood if desired. Furthermore, other application members than that specifically disclosed herein may be used in conjunction with the body member, other forms particularly adapted for this purpose being disclosed in my companion application Serial No.' 550,786, filed July 14, 1931.
