ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to plastering tools and, more specifically, to a texturing device for forming designs in wet plaster on plastered or dry wall ceilings or walls.
2. Description of Related Art
The related art of interest describes various texturing hand tools, but none discloses the present invention. There is a need for a texturing hand tool for plasterers which is simple to use, versatile in application, and economical to produce. The related art will be discussed in the order of perceived relevance to the present invention.
U.S. Pat. No. 3,669,069 issued on Jun. 13, 1972, to Cedric D. Bourboulis describes a tool for texturizing painted surfaces comprising a plurality of tapered S-shaped resilient synthetic rubber petals or flaps which depend from a formable backing member. The petals or flaps are of unequal length. The tool has a removable handle for ease in applying it to wall and ceiling surfaces to place and pound the backing member parallel to the surface being coated to create random patterns. Therefore, no twisting, turning or other manipulation of the tool is required. The tool is distinguishable for its required tapered S-shaped resilient petals or flaps and its limitation to a singular movement of the tool.
U.S. Pat. No. 5,000,671 issued on Mar. 19, 1991, to Ray J. Nolte describes a hand-held, self-cleaning machine for imprinting sculptured designs in mortar, joint compound, clay or cement on walls and ceilings using embossed design rollers. A water jet spray and a vacuum is incorporated in the machine to continuously clean the design roll and vacuum the contaminated water. The hand machine is distinguishable for its mechanized structure and requirement for a continuous cleaning water supply.
U.S. Pat. No. 4,201,801 issued on May 6, 1980, to Kiyoshi Hori describes a method of forming a decorative relief pattern initially painted on an article or a substrate by utilizing a roller with an assortment of relief patterns on the roller. The roller is distinguishable for requiring a relief pattern to form a design in wet paint.
U.S. Des. Pat. No. 419,409 issued on Jan. 25, 2000, to Marlyn L. Stover, Jr. et al. describes a dry wall texturing tool comprising a wide curved blade attached to a pair of horizontal studs by a plurality of wing nuts with a double serrated handle attached perpendicularly to the blade between the two studs. The tool is distinguishable for its curved blade and its handle serrated on both sides.
U.S. Pat. No. 5,524,316 issued on Jun. 11, 1996, to Max Johnson describes a hand tool for decoratively applying plaster on a ceiling comprising a handle attached to a stiff but resilient blade with a serrated distal, longitudinal edge having either two spaced-apart tool alignment marks or a pivot device at one end of the blade. The tool is distinguishable for requiring an elongated serrated blade.
U.S. Pat. No. 3,180,260 issued on Apr. 27, 1965, to Bernard L. Joseph describes a stencil or printing member set and a method of assembling and using the tool. The stencil has a circular three-dimensional polyurethane foam resin pattern adhesively coated on a base consisting of a disc-shaped base of equal diameter. The base is attached to another base of smaller diameter and a terminal rod handle. The stencil coated with paint is applied to a wall perpendicularly to create one design which can differ in thickness due to the difference applied by hand pressure. The stencil tool is distinguishable for requiring a pattern cut in the stencil face.
U.S. Pat. No. 3,817,178 issued on Jun. 18, 1974, to Dean C. Hagen describes a square decorating tool which is coordinated with a chain attached to one wall. The hand tool has a square backing plate having a hook at one end for the chain and a looped handle. A base plate made of either aluminum or magnesium is attached offset to the backing plate. A polyurethane foam pattern is attached to the base plate by an adhesive. The aqueous mixture of lime hydrate and cement is applied to the tool and the ceiling patterned in steps utilizing the chain and a chalked guide line. The tool is distinguishable for its required cut foam pattern and the chain attachment.
U.S. Pat. No. 4,030,414 issued on Jun. 21, 1977, to James T. McGuire describes a one-piece wall paint decorating device comprising a thick rectangular cellulose sponge with a cutout pattern on one side and a handle cut out on the opposite side or on a side. The device is distinguishable for its one-piece cellulose sponge construction.
U.S. Pat. No. 4,123,973 issued on Nov. 7, 1978, to Frank O. Genevase describes a brocading tool for applying paste material in a design on ceilings and walls. The first embodiment uses a spiral pattern of a wire coated with a thick resilient unidentified covering on a reinforced stem on a cylindrical handle. The second embodiment utilizes a radial pattern of fingers supported by individual braces similar to an umbrella attached to a handle. The tool is distinguishable for its required spiral or finger pattern.
U.S. Pat. No. 4,930,179 issued on Jun. 5, 1990, to Paul B. Wright et al. describes a roller paint decorating tool having flexible flaps made of sheepskin or chamois leather to simulate ragging, sponging and rag-rolling effects. The tool is distinguishable for requiring a roller as a substrate for the flexible straps.
U.S. Pat. No. 5,401,231 issued on Mar. 28, 1995, to Jacques O. Hebert describes a texturing roller for applying drywall or plaster to a wall or ceiling comprising multiple leather discs riveted to the roller cylinder. The tool is distinguishable for requiring a textured roller assembly of riveted leather discs.
U.S. Pat. No. 5,580,608 issued on Dec. 3, 1996, to John S. Capoccia describes a splaying tool for imparting a knock-down pattern to a wet topping compound on a ceiling. The tool has a flexible blade held by a base member which is angled 30° to 60° from a second edge member attached to a long handle. The object of the curvature between the blade and the handle requires the handle to be parallel to the wall or ceiling being patterned. The splaying tool is distinguishable for requiring an oriented handle and a lengthy blade.
U.S. Pat. No. 5,695,788 issued on Dec. 9, 1997, to John R. Woods describes a tool for repairing small holes or cracks in damaged walls or recently installed plaster or plasterboard walls by dispensing plaster material, e.g., drywall mud material, spackle, grouting, and cementitious material, from a flat plate having either a flat triangular shape or right-angled plates (for inside or outside wall corners). The plate has a tubular orifice extension for inserting the nozzle of the plaster source. The contacting surface of the base plate has protrusions arranged in triangular fashion. The tool is distinguishable for requiring a construction adapted to receive a nozzle of a supply tube to deposit the plaster material.
None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed.
SUMMARY OF THE INVENTION
The invention is a hand tool device for forming designs in a wet plaster layer laid on a plaster or drywall ceiling. In a preferred embodiment, the tool has a 10 inch diameter face of a vulcanized rubber sheet. The rubber sheet is backed by a burlap layer placed on a metal plate. The rubber sheet and burlap layer are secured on the metal plate by a metal band and a screw clamp. The round plate has a female threaded flange on its bottom surface which accommodates a short section of a threaded metal pipe. The pipe holds a cylindrical wooden handle. The tool is dipped in a plaster mix having a consistency of gravy and is moved in steps in a rolling action across the ceiling surface to form a unified textured design. It is contemplated that other surfaces such as walls, countertops, floors and the like can also be treated with this tool. Furthermore, coating materials other than wall plaster can be utilized with this tool such as plastic, grout, and the like. Many d
