United States Patent TOOL FOR CLEANING UPHOLSTERY AND CARPETS Otto M. Waara, 14903 Bramell, Detroit 23, Mich.

Filed Feb. 26, 1959, Ser. No. 795,743

1 Claim. (Cl. 15114) This invention relates to a manually useable mechanical tool which is expressly designed and particularly constructed for scrubbing and shampooing upholstery and carpets.

Briefly, the preferred embodiment of the invention comprises a suitable handle attached to a U-shaped frame or yoke having opposed parallel arms for mounting multiple rollers and a brush which lend themselves for scrubbing and shampooing upholstery and carpets.

More specifically, the invention in its preferred embodiment is characterized by a suitable handle attached to a U-shaped frame having opposed parallel free ends which are bored adjacent to their extreme ends to provide bearings fora shaft on which are rotatably mounted multiple rollers, said rollers being of absorbent material for the purpose of distributing cleaning fluids to rugs 'and carpets. Scrubbing means are provided by a brush.

The object of my invention is to provide a tool for cleaning upholstery and carpets which does not have any obstructive covers or brackets which protrude to prevent cleaning close to walls and in corners.

Another object of my invention is to provide means whereby the pressure of the brush can be controlled by the simple expediency of changing the angle at which the handle is held, thereby requiring a minimum of effort for increased cleaning efllciency.

The primary object of my invention is to provide a tool with multiple short rollers which distribute fluids more evenly than is possible with conventional long rollers because, upon slight pressure the fluid is squeezed out of the ends of the short absorbent rollers as well as the surface, thereby being distributed more evenly than is possible with long rollers.

Another object of my invention is to provide an improved design which can be manufactured economically.

Other objects, features and advantages will become more readily apparent from the following description and the accompanying sheet of drawings.

In the drawings wherein like characters are employed to designate like parts throughout the views:

Figure 1 is a perspective view with the handle shown fragmentarily;

Figure 2 is a side elevational detail view of the same;

Figure 3 is a view which is approximately like that identified in Figure 2 but with the spring contracted thereby bringing the brush bracket in approximate parallelisrnto the longitudinal plane of the handle;

Figure 4 is a fragmentary detail plan view illustrating how the roller and the brush bracket are assembled on the shaft between the opposed arms of the yoke.

Referring now to the drawings with the aid of reference characters and lead lines, the handle is denoted by and may be of wood or other suitable construction.

11 is a yoke or frame equiped with a socket 12 for said handle and laterally offset spaced parallel arms 11a which are bored adjacent to their ends to provide bearings for axle 22. The median portions of the spaced parallel arms of bracket 13 are bored to provide bearings for pivotally mounting same on axle 22 and the flanged ends 14-15 are fastened to a brush 16 by means of screws 1718 as illustrated in Figure 4. Roller 20 and brush bracket 13 with brush 16 attached are assembled on axle 22 and in yoke 11 in the manner illustrated in Figure 4. R01- lers 19-21 are mounted to rotate on the protruding ends of shaft 22 as illustrated in perspective view Figure 1. Press-on nuts 23 as illustrated in Figures 2. and 3, or other conventional means may be used on the ends of shaft 22 to retain rollers 19 and 21 in position. The median section of the longitudinal portion of the U-shaped bracket 13 is provided with a hole 24 to provide means for pivotally attaching spring 25, opposite end of said spring is pivotally connected to screw eye 26 in the end of handle 10. Flanged stops 13a as illustrated in Figures 2-3-4 prevent bracket 13 from pivoting on its axis beyond the position illustrated in Figure 3. The rollers 192021 can be made of solid materials such as sponge 1 rubber or felt or, said rollers can be made cylindrical and be covered with an absorbent material. In use the rollers and brush are dipped in the cleaning solution and are then worked backward and forward over the surface being cleaned.

It is thought that persons skilled'in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size and arrangement of details and parts such as come within the purview of the invention claimed may be resorted to, in actual practice, if desired.

The construction and use of my invention having now been explained, that which I claim as new and desire to protect by a patent is:

A device of the character described, comprising a yoke having opposed arms and means for attaching a handle, free end portions of said yoke provided with bearings, an axle journaled in said bearings, multiple absorbent rollers, said absorbent rollers equal in length to promote the uniform application of fluids and mounted rotatably on said axle, a U-shaped bracket, median sections of the opposed arms of said bracket provided with bearings parallel to each other for mounting same on said axle between the opposed arms of said yoke, extreme free ends of said U-shaped bracket flanged outwardly at right angles to the longitudinal axis of said opposed arms, a scrubbing element, said scrubbing element afiixed to said flanged free ends, said multiple absorbent rollers spaced apart on said axle by the extreme free end portions of the opposed arms of said yoke in combination with the medially mounted sections of the opposed arms ofsaid U-shaped bracket.
