Patented Dec. 8, 1936 UNITED STATES PATENT OFFICE DUST MOP BUMPER Alfred D. Sund, Santa Rosa, Calif.

4 Claims.

This invention relates to dust mop bumpers, and has special reference to a resilient member adapted to be applied to the handle of a broom, dust mop, or similar cleaning implement, which will prevent marring of window ledges or other objects, against which the handle is struck to dislodge dirt from the broom or mop, and which will assist the rebound of the handle during each stroke to magnify the shock imparted to the broom or mop.

The subject matter described in this specification, and illustrated in the accompanying drawing, was originally part of my Patent No. 2,021,- 335, allowed November 19, 1935, this being a division of the aforesaid patent.

It is an object of the invention to provide a bumper for the handles of brooms or mops which has adjustable clamping means thereon enabling the bumper to be fitted to handles of difierent diameters.

Another object or" the invention is to provide a resilient bumper on which metal parts used for clamping the bumper to the implement handle are protected by portions of the bumper from coming in contact with and marring, objects against which the handle is struck during the operation of shaking dust and dirt from the implement.

Another object of the invention is the provision of a humper which does not require that the broom or mop be held in any particular position during the operation of shaking the dust and dirt therefrom.

The invention possesses other objects and valuable features, some of which, together with the foregoing will be set forth in the specification hereunto annexed. It is to be understood however that the invention is not to be limited to that species shown and described as various other embodiments may be employed within the scope of the appended claims.

Referring to the drawing:

Figure 1 is a side elevational view showing the bumper applied to the handle of a dust mop and the position the latter occupies, in relation to a window, which is shown in light lines, during the operation of cleaning the mop.

Figure 2 is a front elevation, partly in section, of the bumper. The plane of section is indicated by the line 2-2 of Figure 3.

Figure 3 is a vertical sectional View of the bumper. The plane of section is indicated by the line 3--3 of Figure 2.

The invention comprises a rubber bumper, generally indicated by the numeral 4, Figure l, which may be fitted to the handle 5 of a dust mop or broom 6. As is well known, the method employed in cleaning such mops is to pass the handle 5 thereof through an open window I and by striking the handle 5 in successive strokes, against the ledge 8, cause the dirt and dust contained in the mop to be dislodged therefrom. The rubber bumper t, besides providing for protection of the ledge against being marred by the handle 5, during the cleaning operation, provides for added rebound of the mop during each stroke and this added rebound causes deep-seated dirt to be more rapidly released from the mop.

In detail, the bumper, as is shown in Figures 2 and 3, comprises a cylindrical block of rubber provided wtih a central aperture 9 for receiving the mop handle and a peripheral groove II] which provides a pair of end flanges I I. In the groove III is positioned an arcuate strap I2 having upturned ears I3 formed at its ends provided with apertures I4 for receiving a clamp screw I5. This clamp screw, in conjunction with the strap I2, is for diametrically compressing the aperture 9, after the bumper has been positioned on the handle 5, so as to cause the bumper to be securely affixed thereto.

During the operation of striking the bumper against the window ledge, or other solid object, one of the flanges I I will flex to a position where it is interposed between the strap I2 and the ledge thereby protecting the latter against being marred by the strap. At the end of the downward stroke it will be evident that the rubber of the bumper will be compressed materially and this force stored in the bumper, together with that stored in the flexed flange II, will rapidly overcome the momentum of the mop and accelerate the upstroke thereoi thereby imparting a decided shock to the mop and causing dislodgement of dirt therein which would not ordinarily be shaken out.

In addition to the features set forth above it will be seen that a mop equipped with the bumper of my invention may be cleaned without creating bothersome noise to neighbors or day sleepers who may be in the immediate vicinity; will be protected against handle breakage; and will be capable of being more thoroughly cleaned in a shorter time than can a mop not equipped with the bumper.

I claim:

1. A dust mop bumper comprising a resilient member having an aperture therein for receiving the handle of a mop, said member having a peripheral groove therein, and means for compressing said resilient member about said handle, said compressing means being disposed wholly within said peripheral groove.

2. A dust mop bumper comprising a cylindrical resilient member having an aperture therein for receiving the handle of a mop, and means for compressing said resilient member about said handle, said compressing means being disposed below the outermost surface of said member between the periphery thereof and said aperture.

3. A dust mop bumper comprising a cylindrical resilient member having an aperture therein for receiving the handle of a mop, means for compressing said resilient member about said handle, said compressing means being disposed about a portion of the periphery of said member and said aperture, and a pair of flexible flanges extending from said member and projecting radially thereof to points beyond the radial extent of said com pressing means.

4. A dust mop bumper comprising a cylindrical resilient member having an aperture therein for receiving the handle of a mop and means for compressing said resilient member about said handle, said compressing means comprising an arcuate metallic strap about said member, a screw joining the ends of said strap for drawing said ends together, and apair of flexible flanges extending from said member and enclosing said strap and said screw, said flanges being normally disposed in parallel relationship transversely with respect to the axis of said aperture, and portions of each flange being flexible from said normal position to a position parallel with said axis and overlying said strap when said bumper is struck against an object.
