Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application is a continuation in part of and claims priority to U.S. patent application Ser. No. 13/086,334, entitled “System and method for capturing resultant dust from power tool operation,” and filed on Apr. 13, 2011 by Jack M. King, Jr. The contents of the above mentioned application are hereby incorporated by reference. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present disclosure relates to power tool accessories, and more particularly to power tool accessories for capturing dust and debris within a receptacle. 
         [0004]    2. Description of Related Art 
         [0005]    The removal of flooring tile is a dirty and time-consuming process. Power driven chisels are often employed to speed the removal of the tile and its backing adhesive material. However, this process results in a large amount of dust and debris that is ejected into the ambient air. A large amount of preparation time is needed in order to protect surrounding areas from being contaminated with dust. Additionally, the health of those in the area is negatively affected by the dust. Furthermore, environmental regulations in certain areas prohibit the escape of the removed dust into the atmosphere. 
         [0006]    In order to combat the dust, many tools have been conceived of. Various apparatuses include encasing the operating end of a power tool with a housing and attaching a vacuum to the housing. In the majority of these tools, the housing is cylindrical and has a single large opening through which the dust is captured. The current state of the art has several shortcomings. First of all, the location of the vacuum attachment in the prior art does not maximize the location and direction of air flow in order to capture the most dust. Second, the large opening does not allow the tool to reach certain places, such as in corners and underneath cabinets. Third, the durability of many products on the market is suspect. Fourth, the cylindrical shape of the operating end of the apparatuses does not provide a stable base on which to move the tool along the floor. Fifth, some of the products would often get clogged with pieces of debris. Therefore, a need arose for the present invention. 
         [0007]    Because dust and debris can scatter when it is shaken or moved into or within a trash or debris receptacle for the purpose of collection and disposal, the dust and debris can become airborne and escape the confines of the trash or debris receptacle. Therefore, a need arose for the present vacuum device for capturing dust within a receptacle. 
         [0008]    Further, because large pieces of debris may become projectiles during use of a power tool having a tool bit, a need arose for a device for capturing projectile debris during tile removal. 
         [0009]    So as to reduce the complexity and length of the Detailed Specification, and to fully establish the state of the art in certain areas of technology, Applicant(s) herein expressly incorporate(s) by reference all of the following materials identified in each numbered paragraph below.

         [0015]    U.S. Pat. No. 6,514,131 discloses a power tool having a dust suction device integrated into its housing. The hollow interior housing of the power tool itself is designed to fit flush with the surface being operated on. Dust is collected in this housing due to its close relation to the surface. Dust is transferred from this interior hollow volume by a suction device integrated into the tool through an opening which leads to a dust collection box which is also part of the tool itself. Dust is collected in the dust collection box which must be emptied when full. 
         [0016]    U.S. Pat. No. 6,641,634 discloses a manual machine tool including a vacuum device situated in its housing. The housing of the machine tool itself has a hollow portion that fits flush with the surface being operated upon by the tool. Dust is trapped inside this hollow portion and may be ejected into an attached dust box through an ejection opening. 
         [0017]    U.S. Pat. No. 6,854,937 discloses a dust attachment which is used with a spiral saw power tool. A hollow attachment is fitted over the operating end of a spiral saw power tool with an airtight attachment furthest away from the operating end of the power tool. The end closest to the operating end of the power tool is hollow and collects dust from the operating end of the power tool through the same opening which allows the operating end of the power tool to reach the surface being operated upon. The forward end of the attachment, through which the operating bit of the power tool protrudes, is flat in one continuous plane and only has the single opening. Dust is removed from this interior volume through a hollow arm, the interior of which connects to the hollow interior of the attachment, by the suction force of an attached vacuum hose. 
         [0018]    U.S. Pat. No. 7,281,886 discloses a suction device that is used with a power drilling tool with an aeration device fixedly connected by a suction conduit with the suction head. A hollow housing is fitted to the exterior of a power tool and does not encase any of the body of the power tool. One end of the housing forms a suction head around the tool bit and draws dust into the hollow body of the housing. This suction end lies flush with the surface being operated upon and only encompasses a portion of the operating bit nearest the surface. Dust is drawn to the opposite end of the housing by an internal fan driven by an electric motor internal to the device. Dust is accumulated in the end of the device housing the fan and motor. 
         [0019]    U.S. Pat. No. 7,740,086 discloses a suction device for a hammer drill having a receiving space which partially encloses a working tool. The suction device attaches over the operating end of a pick power tool. One end of the device attaches to the body of the power tool while the other end has a plurality of holes which contact the surface being operated upon. A portion of the device is articulated to provide flexibility to the body of the device, which is hollow, and to maintain contact between the device and the surface being operated upon. Dust is drawn into the hollow body of the device through the holes that contact the surface, and out of the device through a single hollow connection for a vacuum hose. 
         [0020]    U.S. Pat. No. 7,797,794 discloses a suction device for a pick power tool with a vacuum source and a baffle wall.

         [0043]    Aspects and applications of the invention presented here are described below in the drawings and detailed description of the invention. Unless specifically noted, it is intended that the words and phrases in the specification and the claims be given their plain, ordinary, and accustomed meaning to those of ordinary skill in the applicable arts. The inventors are fully aware that they can be their own lexicographers if desired. The inventors expressly elect, as their own lexicographers, to use only the plain and ordinary meaning of terms in the specification and claims unless they clearly state otherwise and then further, expressly set forth the “special” definition of that term and explain how it differs from the plain and ordinary meaning Absent such clear statements of intent to apply a “special” definition, it is the inventors&#39; intent and desire that the simple, plain and ordinary meaning to the terms be applied to the interpretation of the specification and claims. 
         [0044]    The inventors are also aware of the normal precepts of English grammar. Thus, if a noun, term, or phrase is intended to be further characterized, specified, or narrowed in some way, then such noun, term, or phrase will expressly include additional adjectives, descriptive terms, or other modifiers in accordance with the normal precepts of English grammar. Absent the use of such adjectives, descriptive terms, or modifiers, it is the intent that such nouns, terms, or phrases be given their plain, and ordinary English meaning to those skilled in the applicable arts as set forth above. 
         [0045]    Further, the inventors are fully informed of the standards and application of the special provisions of 35 U.S.C. §112, ¶ 6. Thus, the use of the words “function,” “means” or “step” in the Detailed Description or Description of the Drawings or claims is not intended to somehow indicate a desire to invoke the special provisions of 35 U.S.C. §112, ¶ 6, to define the invention. To the contrary, if the provisions of 35 U.S.C. §112, ¶ 6 are sought to be invoked to define the inventions, the claims will specifically and expressly state the exact phrases “means for” or “step for, and will also recite the word “function” (i.e., will state “means for performing the function of [insert function]”), without also reciting in such phrases any structure, material or act in support of the function. Thus, even when the claims recite a “means for performing the function of . . . ” or “step for performing the function of . . . ,” if the claims also recite any structure, material or acts in support of that means or step, or that perform the recited function, then it is the clear intention of the inventors not to invoke the provisions of 35 U.S.C. §112, ¶ 6. Moreover, even if the provisions of 35 U.S.C. §112, ¶ 6 are invoked to define the claimed inventions, it is intended that the inventions not be limited only to the specific structure, material or acts that are described in the preferred embodiments, but in addition, include any and all structures, materials or acts that perform the claimed function as described in alternative embodiments or forms of the invention, or that are well known present or later-developed, equivalent structures, material or acts for performing the claimed function.

       DETAILED DESCRIPTION OF THE INVENTION 
       [0076]    In the following description, and for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the various aspects of the invention. It will be understood, however, by those skilled in the relevant arts, that the present invention may be practiced without these specific details. In other instances, known structures and devices are shown or discussed more generally in order to avoid obscuring the invention. In many cases, a description of the operation is sufficient to enable one to implement the various forms of the invention, particularly when the operation is to be implemented in software. It should be noted that there are many different and alternative configurations, devices and technologies to which the disclosed inventions may be applied. The full scope of the inventions is not limited to the examples that are described below. 
         [0077]    Device for Collecting Dust from a Power Tool 
         [0078]    Referring to  FIG. 1 , a top view of a device for collecting dust from a power tool  100  is illustrated according to an embodiment of the invention. The device  100  comprises a housing  110  that may have a substantially cylindrical shape. The housing  110  has a first end  112  that tapers to a tool bit opening  198 . The angle and length of the taper may be of any angle or length, but is preferably such that the first end  112  may fit into narrow areas, such as corners of a room or underneath the toe-kick of cabinets. The first end  112  has a plurality of suction ports  122  through which air and dust may flow into the housing  110 . A second end  114  of the housing  110  is configured to couple to a power tool. In one embodiment, a clamp  180  is used to couple the housing  110  to the power tool. A plurality of air intake passages  150  are shown coupled to an exterior surface  160  of the housing  110 . The air intake passages  150  are coupled to an exit passage  155 . The exit passage  155  is configured to couple to a vacuum. The exit passage  155  may be configured to couple to an interior or exterior of a vacuum hose, or may couple to the vacuum by any other method known in the art. 
         [0079]    In some embodiments, the housing  110  may be rectangular, or any other shape capable of coupling to a power tool. The housing  110  may be narrower than illustrated if it is to be coupled to a smaller power tool, or conversely the housing  110  may be broader than illustrated to fit larger tools. In one embodiment the housing  110  may be significantly elongated to fit power tools with long bodies or long actuating distances. In one embodiment the housing  110  may be significantly shorter to fit power tools with a short body or a short actuating distance from the body to the operating end of the power tool. In one embodiment the housing  110  may have suction ports  122  located along any part of its length. The housing  110  may also be referred to as a sheath or a casing. 
         [0080]    The air intake passages  150  are shown coupled to opposite sides of the housing  110 . The air intake passages  150 , or vacuum channels, may be positioned to maximize the effectiveness of the air flow through the suction ports  122 . Additionally, by positioning the air intake passages  150  adjacent to the first end  112 , the dust is collected before coming in contact with the power tool, preventing damage and reducing maintenance to the power tool. The use of multiple air intake passages  150  may increase the amount of dust that is capable of being removed from the local atmosphere. In other embodiments, the air intake passages  150  may be located at different positions. For example, the air intake passages  150  may be located adjacent to the second end  114  in order to allow the device  100  to reach narrow access areas. The air intake passages  150  may be curved such that they come together. Alternatively, the air intake passages may be straight or comprise a plurality of straight sections such that they meet at or near the exit passage  155 . In one embodiment, the air intake passages  150  do not meet at a common exit passage  155 , but rather have separate exit passages  155  that each couple to a vacuum source. Additionally, more than two air intake passages  150  may be used to improve the distribution of air flow throughout the device  100 , reducing the chances of clogging. 
         [0081]    In the illustrated embodiment, each air intake passage  150  comprises a first passage sections  150   a , and a second passage section  150   b . The two passage sections  150   a ,  150   b  are substantially straight, and the first passage sections  150   a  couple to the exterior surface  160  of the housing  110 . The second passage sections  150   b  are coupled to the exit passage  155 . 
         [0082]    The first end  112  of the housing  110  comprises at least one suction port  122 . The suction ports  122 , or suction holes, as shown are circular, however they may be of any shape such as square, elliptical, or rectangular. There may be any number of suction ports  122 . For example, there may be a large enough amount of suction ports  122  such that the first end  112  may essentially comprise a screen or grating. While some dust may be collected through the tool bit opening  198 , much of the dust is collected through the suction ports  122 . The suction ports  122  focus the air flow around the first end  112  such that nearly all ambient dust particles are removed from the local area. This prevents dust from contaminating nearby areas or escaping into the atmosphere. Rather than being formed at an angle perpendicular to the first end  112 , the suction ports  122  may be formed substantially parallel to a central axis of the housing  110 . This horizontal angle allows the air to flow into the housing  110  with fewer turns, increasing the effectiveness of the dust removal. 
         [0083]    The device  100  further comprises a lip  190 . The lip  190  may be made of a durable material such as case-hardened steel, heat-treated steel, or any other material known to one of ordinary skill in the art. The lip  190  is coupled to the first end  112  of the housing  110 . The lip  190  comprises the tool bit opening  198 , which extends from the first end  112  of the housing  110  through the lip  190  and allows air to flow through the lip  190  and into the housing  110 . The lip may further comprise lip suction ports  192 . The lip suction ports  192  allow air to flow through, collecting dust and providing a source of ambient air to cool a tool bit which may extend through the lip  190 . 
         [0084]    Over an extended period of time, the lip  190  may deteriorate from prolonged use. When the lip  190  is significantly worn out, it may be detached from the housing  110  and a new lip may be installed. This allows the device  100  to have a longer lifespan. The new lip may be welded to the device  100  or attached by any other way known to one of ordinary skill in the art. Alternatively, the device  100  may be used without a lip  190 . 
         [0085]    The device  100  further comprises vent holes  170 . In this embodiment, two vent holes  770  are located on a top portion of the housing  110  and proximate to the second end  114 . However, any number of vent holes  170  may be used, and they may be located on the side or lower portion of the housing  110 , or further from the second end  114 . The vent holes  170  allow air to flow through the housing  110  in a direction from the second end  114  toward the first end  112 . This air flow prevents dust and debris from accumulating inside the first end  114  of the housing  110 . This keeps the dust and debris from interfering with any power tool, such as a chipping hammer, which is coupled to the device  100 , improving the functionality and lifetime of the power tool. Additionally, the vent holes  170  allow cool air to flow into the housing  110  to cool the power tool and the device  100 .

The air intake passages  150  are shown extending away from the first end  112  at an angle relative to the housing  110 . The angle of the air intake passages  150  may vary according to the desired purpose of the device  100 . For example, in embodiments designed to fit into narrow locations, the air intake passages  150  may be positioned at a lesser angle relative to the housing  110  such that the device  100  has a smaller cross-sectional area near the first end  112 . The lip  190  may also be tapered. Although only on the top of the housing  110  in this embodiment, the vent holes  170  may also be located substantially at the bottom or sides of the housing  110 . 
         [0087]    Referring to  FIG. 3 , a rear view of the clamp  180  is illustrated according to an embodiment of the invention.

The clamp  180  may further comprise a nut which may be coupled to the neck portions  350  such that the nut remains in place when the nut and bolt  330  are not engaged. Alternatively, the nut may be a separate detachable piece. The bolt  330  may thread into the nut, or alternatively the neck portions  350  may be threaded such that the bolt  330  engages with the neck portions  350 , and the nut is not required. The bolt  330  may comprise a locking cam, in which the bolt  330  requires no tools to tighten and loosen the clamp  180 . In another embodiment, the bolt  330  comprises a cotter pin to keep it in place. The bolt  330  may further comprise a retaining member that couples to the bolt  330  between the neck portions  350  such that the bolt remains coupled to a neck portion  350  when not engaged with the opposing neck portion  350 . An interior portion  360  of the collar members  320  may comprise an elastic material such as rubber in order to make a tight connection with the power tool. Alternatively, an interior portion  360  of the collar members  320  may be comprised of steel, machined to make a tight connection with the power tool. The clamp may further comprise clamp vent holes  370 . The clamp vent holes  370  may be located on the collar members  320  and have a similar function to the vent holes  170 .
