Abstract
A texture material applicator and a method for applying texture material to a wall or ceiling surface to produce a desired surface texture and appearance. A selected one of several different rotary dispenser inserts is rotated within a chamber in a body of the applicator, picking up a quantity of texture material on each of a plurality of spatter elements. The spatter elements are resiliently bent by a regulator and throw bits or drops of texture material out from the chamber and radially outward through an outlet opening in the body of the applicator as the spatter elements spring away from a release edge of the regulator. Different textures may be provided by using different rotary dispenser inserts having different spatter elements differently located on the rotary dispenser.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
(24) Referring now to the drawings that form a part of the disclosure herein, in
(25) The right end plate 46 defines an opening 48 that extends through the right end plate as a bearing, and a shaft extension 50 portion of the rotary dispenser insert extends outwardly through the opening 48. Threads may be machined on the outer end of the shaft extension so that a crank or another mechanism may be attached drivingly to the shaft extension 50 of the insert and may be used to rotate the rotary dispenser insert 44 within the chamber 34. The bearing cavity 42 or receptacle for the first end 43 of a rotary dispenser insert 44 and the opening 48 for a shaft extension 50 of an insert 44 jointly define a central axis 52 of the chamber about which a rotary dispenser insert can be rotated.
(26) The left and right end plate members 40 and 46 defining the ends of the body 32 may extend downward below the chamber 34 and have a pair of respective bottom margins 54 and 56 defining a base plane or bottom of the body 32. Additionally, there may be a support base 58 extending forward and downward from the middle of the body 32 to the base plane, so that the body may conveniently be placed on a table or other flat horizontal surface and remain in an upright orientation as shown in
(27) As may be seen in
(28) Referring now also to
(29) Extending upwardly from an upper margin of the opening in the front of the chamber there is a flat front member 82, and a slot 84 is defined behind the front member. The slot 84 defines a plane 86 that is tangential to an imaginary cylinder 88 centered on the central axis 52 of rotation but having a radius somewhat less than the radius of the interior of the chamber 34. A regulator 90, which may be a flat plate, is mounted in the slot 84 so that it is adjustably movable along the slot, generally along an interior side of the front side member. The regulator 90 has a bottom margin that may be straight and may extend parallel with the central axis 52 of the body and acts as a spatter element release edge 92. The regulator 90 may be movable along the slot 84, between a retracted position, in which the spatter element release edge 92 may be outside the cylindrical cavity defined by the interior surface of the majority of the chamber 34, and a position such as that shown in
(30) The rotary dispenser insert 44 includes a central body 96, which may be generally in the form of a cylindrical shaft. Several spatter elements 98, etc. are mounted in the central body 96, arranged in a pattern intended to deliver texture material from the chamber 32 to produce a particular type of texture pattern, as will be explained in greater detail below. Other rotary dispenser inserts 44, etc. having several differing arrangements and types of spatter elements may be used to produce correspondingly different textures.
(31) Each of the different rotary dispenser inserts 44, etc. includes a first inner, or left, end 43 of a size and cylindrical shape that fits snugly and rotatably within the bearing cavity or receptacle 42 defined in the left end plate 40 of the body 32. Each of the rotary dispenser inserts 44, etc. also has an outer shaft extension 50 of a size that fits snugly through the bearing opening 48 defined in the removable right end plate 46 of the body 32.
(32) A hand crank 100, shown in
(33) The spatter elements 98, etc. of each rotary dispenser insert 44, etc. are mounted so as to extend generally radially from the central body 96, etc. of the particular rotary dispenser insert. The rotary dispenser inserts may all have similar outer diameters that may range from 2 or 3 mm less than the interior diameter 36 of the cylindrical part of the chamber 34 of the body 32 to 2 or 3 mm more than the interior diameter 36 of the chamber 34. A rotary dispenser insert 44, etc. may thus have an interference fit within the cylindrical part of the chamber 34. The individual spatter elements 98, etc. may be resiliently flexible, and may be mounted resiliently in receptacles in the central body 96, etc. of a respective rotary dispenser insert 44, etc.
(34) As shown in
(35) A surface texture material control valve 116 is located in the upper portion of the applicator 30, in a conduit leading from the texture material container receptacle 110 to the top of the chamber 34 within the body 32. A valve control lever 118 is available on the left side of the applicator, and a scale 120 representing the degree to which the valve is open may be provided on the left side of the body 32, adjacent the valve control lever 118. The control valve 116 can be adjusted conveniently to control the rate at which surface texture material is able to flow into the chamber 34 from the surface texture material container 112. Markings of the scale 120 provide easy reference for adjustment of the control valve 116 for application of surface texture material using a particular rotary dispenser insert to create a particular surface texture.
(36) Suitable surface texture material is easily prepared from commercially available premixed drywall joint compound, or “mud,” that can be mixed with an appropriate amount of additional water to produce surface texture material with a useful, usually cream-like, consistency that can be applied using the applicator 30 disclosed herein. The texture material can be prepared in the surface texture material container bottle 112, shown in
(37) The texture material may be prepared from, for example, commercially available premixed all-purpose drywall joint compound, such as Hamilton “A P” drywall joint compound, prepared to form a Standard Texture Mix by mixing in a proportion of approximately 72 ounces water to a 3.5 gallon box of premixed joint compound. Alternatively, a thinner mix of texture material may be made by use of 96 ounces water to a 3.5 gallon box of premixed joint compound, or a different product such as “Hamilton respray acoustic” may be used when mixed to a desired consistency.
(38) As may be seen in
(39) When texture material is applied using the first rotary dispenser insert 44a the regulator 90 is adjusted so that its spatter element release edge 92 is located to extend a selected distance into the cylindrical shape of the chamber 34 as shown, for example, in
(40) The applicator 30 is prepared for use by first removing the right end plate 46. This is done by removing the locking screw 72 and twisting the right end cover plate 46 counterclockwise, moving the pins 66 in the slots 64 to release the bayonet mount. A rotary dispenser insert such as the insert 44a described above, chosen from among different available inserts 44, 44a, etc. to produce a desired texture, is placed into the chamber 34 so that its inner end 43 rests in the bearing cavity 42 in the left end plate 40. The right end plate 46 is replaced and secured with the locking screw 72, and the handcrank 100 may then be threaded onto the outer end of the shaft extension 50. The control valve 116 on the body of the applicator is closed. A cap (not shown) is removed from a container 112 of texture material, the body of the applicator 30 is inverted, and the receptacle portion 110 is screwed onto the open top of the container 112, with the control valve 116 kept closed. The applicator 30 may then be turned upright so that the container 112 of texture material is inverted above the body 32. The hex wrench 74 may then be used to open the air inlet valve 114 on the now upwardly-exposed bottom of the container 112.
(41) Keeping the applicator 30 to 40 centimeters from the surface of a practice area, a user may begin turning the crank 100 on the right side of the body 32 while slowly opening the material control valve 116 on the left side. When the texture material is accumulating consistently with the desired appearance, the location of the valve lever 118 on the scale 120 should be noted, so that the control valve 116 can be opened again to the right degree without experimentation. Between applications of texture material to different areas being textured the control valve 116 should be closed so that the chamber 34 does not become flooded with texture material. When application is finished the air inlet valve 114 and the material control valve 116 should both be closed. The applicator 30 can be taken apart and washed out with water (if the Hamilton “A P” drywall mud mixed as described above has been used as the texture material.)
(42) A second rotary dispenser insert 44b is shown in
(43) As the dispenser insert 44b is rotated along and past the regulator 90 each spatter element 142, in turn, is forced to bend until its outer end passes free from the spatter element releasing edge 92 of the regulator 90. At that time the stem 148 of the spatter element springs back toward its original radial orientation and the drop of texture material is thrown forward and outward, through the opening 76, as the spatter element 142 springs beyond its original orientation and then returns to its original orientation, as indicated by the arrows 154 and 156 in
(44) A third rotary dispenser insert 44c is shown in
(45) Each of the spatter elements 166 of the third rotary dispenser insert 44c has a relatively thick and stiff but resiliently flexible stem 168 whose base, or radially inner end 170 is mounted separately in the central body 162. The spatter elements 166 also may be of a polymeric plastic material such as weed trimmer line with the stem 168 having a diameter of about 2.92 mm. Each stem 168 may be curved slightly in a rearward direction relative to the usual direction of rotation of the third dispenser insert 44c. At a radially outer end of each spatter element stem 168 there is a small carrier member 174. The carrier member 174 may resemble a tiny paddle or spoon and may include a small depression 176 in which a quantity of texture material is picked up and carried as the third rotary dispenser insert 44c is rotated in the direction of the arrow 172 within the chamber 34. The diameter 178 of the third rotary dispenser insert 44c is about equal to the interior diameter 36 of the chamber 34, so that as the third rotary dispenser insert 44c is rotated the small carrier members 174 may lightly touch the interior surfaces of the chamber 34.
(46) The regulator 90 may be located in the slot 84 extending into the chamber 34 far enough to obstruct the carrier members 174 enough to bend the stems 168 of the spatter elements 166 slightly as the rotor of dispenser element 44c is rotated. When the carrier members 174 pass clear of the spatter element release edge 92 of the regulator 90, the individual carrier members 174 spring fee and throw large drops of texture material radially out from the chamber 34 through the opening 76. The drops of texture material that can be thrown by the carrier members 174 are relatively large by comparison with the drops 136 that can be thrown by the spatter elements of the first and second rotary dispenser inserts 44a and 44b discussed above, since each carrier member 174 may have a radial length 180 of 7.9 mm and an axial width 182 of 6.4 mm, for example. Relatively coarse textures, such as those ceiling textures shown in
(47) A fourth rotary dispenser insert 44d shown in
(48) The regulator 90 can be adjusted to bend the spatter elements 188 back a small amount as the fourth rotary dispenser insert 44d is rotated, and when the spatter elements 188 pass by the spatter element release edge 92 of the regulator 90 and throw droplets of texture material the result can be a medium orange peel texture 198 as shown in
(49) In
(50) From the foregoing it can be seen that the applicator described above can be used to apply texture material to a wall or ceiling to reliably produce any of several different commonly used textures, by using a selected one of the rotary dispenser inserts 44, 44a, etc. in the applicator 30 to apply texture material received in the chamber 34 at a rate controlled by the adjustment of the inlet control valve 116 and with the regulator 90 adjusted to a location in which the spatter elements 98, 128, etc. are bent and then released to throw texture material toward a wall or ceiling.
(51) The terms and expressions which have been employed in the foregoing specification are used therein as terms of description and not of limitation, and there is no intention in the use of such terms and expressions of excluding equivalents of the features shown and described or portions thereof, it being recognized that the scope of the invention is defined and limited only by the claims which follow.
