CLEANING-TOOL.

Patented Mar. 26, 1912.

Application filed Jannary 27, 1908. Serial No. 412,710.

To all whom it may concern Be it known that I, IRA H. SPENCER, a' citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, have invented a new and Improved Cleaning-Tool, of which the following is a specification.

My invention relates to the class of cleaning tools more especially adapted for use in connection with pneumatic cleaning, and the object of my invention is to provide a tool of this class having numerous novel features of advantage and utility. A form of tool in the use of which this object may be attained is illustrated in the accompanying drawings, in which-- Figure 1 is a view in side elevation of a tool embodyin my invention. Fig. 2 is a bottom view 0 the same. Fig. 3 is a view in 1central transverse section through the too In the use of pneumatic. cleaning tools prior to my invention it has been found difficult to thoroughly remove the dust and dirt from certain structures as linoleum,-oilcl'oth and the like such surfaces after having been cleaned having adusty appearance. I have found by experiment that by using a comparatively smooth fibered mouth-piece this dirt and dust may 'be thoroughly removed so that such surfaces as linoleum, oilcloth and the like after having been cleaned will be free from this dusty a pearance. It is desirable that such a tool may also be constructed to be used in connection with a brush in which case the flexible fiber mouthpiece should project to a point near the outer end of the bristles. It is therefore important that the parts znall be so constructed and arranged that the suction through the tool will not cause the comparatively thin, flexible mouth-piece to collapse and be drawn inward, thus obstructing the intake opening.

I have provided a tool in which the flexible fibrous mouth-piece is maintained in approximately its normal form, such a str uc-' ture being illustrated in the accompanying drawings, in which the numeral 6 denotes the head of the tool having a neck 7 to which a nipple, hose or like part may be connected. This neck has an opening 8 leading into a chamber 9 in the head. A shoulder 10 is formed extending about the lower portion of the head and in this shouldered part a recess 11 is formed. A base 12 of any suitable material is secured within this recess, and extending into this base are the bristles 13 of abrush which are secured in any ordinary manner. A buffer 14 extends about theouter surface of the flange 15 which partially forms the recess.

Within the recess 11 is located a support 16. A mouth 17 opens from the chamber 9, this mouth forming an intake opening for the flow of air into the tool and through the structure. The support 16 extends completely about the mouth-17 and is extended to a point to thoroughly support a mouthpiece lS. This mouth-piece is formed of leather or other suitable fiber, the edge of the mouth-piece being located approximately in the plane of the brushing surface of the bristles of the brush. This mouthpiece should extcnd some distance beyond the support forming the mouth proper in order that it may work effectually for the purpose intended, and the support 16 is projected within this mouth-piece to a distance to sufliciently support the mouth-piece from collapse under the pressure exerted by the air..used for cleaning purposes.

The mouth-piece 18 is constructed of leather or other similar suitable material in order that a surface may be thoroughly cleaned by the rubbing contact. In order to produce the best results thismouth-piece is made comparatively flexible. The intake opening or mouth, in order to dispose of the water, dirt, etc., is of comparatively large area and there is, therefore, a tendency to collapse the mouth-piece and cause it to obstruct the opening into the tool. The support 16 is therefore extended downward to a point somewhat close to the edge of the mouth-piece, in order to prevent such collapse, so that satisfactory results shall be produced in the cleaning operation.

While the support 16 is shown and described asbeing continuous and extending completely around the mouth, it is not-,essential to the invention that it shall be so formed.

The brush may be easily removed for the purpose of interchange or renewal and the mouth-piece may also be easily and quickly removed for like purpose, the construction of the parts including the leather mouthpiece providing means for frictionally holding both the brush and said mouth-piece in place.

I claim' 7 1. A head having a chamber and-a projection extending from the side of the head and having an opening into said chamber, a flange surrounding the lower side of the head, a support projecting from within said flange, and a mouth-piece secured within said flange and extending about said sup port.

2. A head having a chamber with an outlet therefrom and an intake opening thereto, a shoulder formed upon the head and having a recess, a brush base located within said recess and with bristles extending therefrom, a mouth-piece located within an opening in the brush base, and a support for the mouth-piece projecting from the head within said mouth-piece but terminating short of the edge thereof.

3. A head having a chamber with an outlet therefrom and an intake opening thereto, a shoulder formed upon the head and. having a recess, -a support integrally formed with said head and project-ing through said recess, a mouth-piece surrounding said support and with its edge projecting beyond the edge of the support, and a brush base having bristles and located within said recess.

4. A head having a chamber with an outlet therefrom and an intake opening, a support extending about said intake opening, a flange extending about the head at a distan'ce from the support and forming a recess, a mouth-piece of flexible fibrous material located against said support and projecting beyond its edge, and a brush removably secured within said recess between the mouth-piece and flange.

having an intake-opening, a brush disposed about said intake opening, and'a wiper band interposed between the brush and the intake opening and located adjacent to said opening, substantially as set forth.

' IRA'H. SPENCER.
