Abstract
Description
- The present invention relates to portable self contained apparatus used for the application of bulk adhesive mastic material and roofing materials associated therein.
- Roofing materials have been used for centuries to adequately seal a roof structure to prevent the encroachment of water and other elements. These materials have developed over time from straw, thatch and mud type roofs to shingles and roofing felt, along with metal roofs and composite materials such as tile. These materials are all designed to provide a cost effective method of sealing a roofing structure from the elements to prevent inherent damage to the building structure and provide a dry, comfortable living or working environment for the occupants of the structure.
- One type of roof commonly used in the commercial roofing industry is a composite roof which utilizes a felt or composite roofing material applied over the roof's structural surface and secured with an unheated viscous adhesive material such as roofing mastic. The roofing mastic serves to adhere the felt roofing material to the top of the roof structure. Once the felt or other impermeable material is in place, mineral granules or gravel or other similar materials are usually applied on top of the completed roofing membrane for protection from the ultraviolet rays of the sun, hail, snow and other environmental conditions.
- One significant problem which exists during commercial roofing operations is the application of the adhesive mastic material to a roofing surface, which requires significant volumes of mastic material to be applied to the roofing surface. To accommodate transporting the adhesive mastic material from the ground level to the roofing surface, large cranes and/or self contained truck pumping units are required which are expensive and require a significant capital investment and trained manpower to operate. These self contained units typically weigh thousands of pounds and hold hundreds of gallons of mastic material in one or more compartments. Further, the pumping equipment necessary to pump high volumes of extremely viscous mastic material from a street level to a roofing surface is significant, and the horse power required and fuel associated therein is not cost effective for smaller roofing surfaces. One such apparatus is described in U.S. Pat. No. 5,358,347 to Morris, which discloses a roof mastic applicator which is used in connection with a large reservoir positioned on the ground level and interconnected to a larger pump and associated truck to transport the mastic material to a roofing surface.
- Accordingly, a significant need exists for a portable mastic application apparatus which may be operated by one man and which can be used in conjunction with smaller mastic containers such as five gallon pails which can be transported quickly and easily without the necessity of heavy pumping equipment and trucks. There is an additional need for a system and method for applying the adhesive mastic material to a roofing surface while simultaneously applying the bulk felt roofing material on top of the mastic material at the same time, thus saving significant time and expense. Finally, there is an additional need for an apparatus which can simultaneously apply the roofing mastic material and a bulk granular material such as mineral granules, at the same time. Accordingly, an apparatus and associated method which are designed to address these problems are provided herein as set forth below.
- It is thus one aspect of the present invention to provide a self contained, portable pumping apparatus which is adapted to apply an adhesive mastic material to a roofing surface, and which can be operated by one person. Alternatively, the apparatus may be used to apply sealing materials to asphalt driveways, parking lots and other surfaces. Thus, in one embodiment of the present invention, a hand cart is provided which is controlled by one man and which supports a small container of mastic material and an associated pump, which is connected to a discharge manifold. The discharge manifold is designed to selectively apply a predetermined volume of mastic material to a roofing surface, the thickness of which can be controlled by the speed of operation of the self-contained unit. The mastic material is generally stored in a small container such as a 5-10 gallon pail which can easily be transported by one or two men to a roofing surface, as opposed to requiring a large pumping unit positioned on the ground level or the lifting of a large bulk container with a crane or other similar device.
- It is another aspect of the present invention to provide a spreading means which applies a consistent thickness of mastic material on the roofing surface. Thus in one embodiment of the present invention a spreader bar is interconnected to the discharge manifold in a downstream position and which simultaneously spreads the mastic material on the roofing surface as it is discharged from a discharge port or a plurality of valves. In a further embodiment of the present invention, an oscillating motion may be applied to the spreader bar which further enhances the uniform application of the mastic material to the roofing surface.
- It is yet another aspect of the present invention to provide a portable pumping unit which can be controlled from pneumatic compressed air or other readily available power sources common to the construction industry. Thus in other embodiments of the present invention a small gas operated pump may be used or an electric pump with sufficient horsepower to pump a viscous mastic material from a container through a discharge manifold on to a roofing surface. As discussed herein, the term “adhesive mastic” applies to all types of viscous, adhesive materials commonly used in the construction and roofing trades, as well as sealants for asphalt driveways and other surfaces. One example of such a material is an asphaltic modified bitumen adhesive such as modified bitumen adhesive (MBR) which is manufactured and sold by the Johns Manvillem Companies.
- It is another aspect of the present invention to provide a device which can apply a mastic material and a bulk roofing material such as rolled felt simultaneously. Thus, in one embodiment of the present invention a support member is operably interconnected to the frame of the portable apparatus and which extends outwardly in a position immediately downstream from the discharge manifold. As the adhesive mastic is selectively applied to the roofing surface, the bulk roofing material may be rolled on to the roofing surface simultaneously, yet requiring only one man to operate the machine.
- In a further aspect of the present invention, a bulk discharge container may be mounted downstream of the discharge manifold, and which applies a bulk granular material such as mineral granules or gravel. Thus, in one embodiment of the present invention the support member may be used to hold a container similar to a fertilizer spreader and which can hold between five and fifty pounds of mineral granules or pea gravel, or other similar materials which can be selectively dispensed on top of the mastic in applications where a felt roofing material or other similar materials are not used, or used in combination therein. Alternatively, the granular materials could be dispensed independently with the same portable machine and without applying the mastic material.
- It is yet another aspect of the present invention that the portable apparatus be self propelled to assist the operator. In one embodiment of the present invention, a small motor may be used with associated gears, chains or belts interconnected to the wheels to provide a constant speed of travel, and to reduce the fatigue associated with operating the machine on a hot roofing surface.
- It is yet another aspect of the present invention to provide a hand held wand which may be interconnected to the discharge end of the pump in combination with the discharge manifold. In this application, an operator may selectively operate the handheld wand to provide a single, selective bead of mastic material along the lap edge of roll roofing in a predetermined location, without utilizing the discharge manifold and associated dispensing ports. In this embodiment, the handheld wand may have a trigger mechanism or other similar apparatus which is used by the operator to selectively control the volume of mastic dispensed from the wand.
- It is yet another aspect of the present invention to provide a separate manifold that can apply a continuous bead of roofing insulation adhesive to and along the top flanges of a structured steel roof deck so to apply the viscous adhesive in ribbons on varying and selective locations and varying rates and locations for the purpose of installing preformed roof insulation boards.
- Thus, in one aspect of the present invention, a portable apparatus which is adapted for applying an adhesive mastic and roofing material is provided herein, and comprising:
- a frame;
- at least one wheel rotatably interconnected to said frame;
- a platform interconnected to said frame for supporting a container of the adhesive mastic material;
- a pump interconnected to said frame and comprising a suction end and a discharge end, said suction end operably positioned to communicate with the container of the adhesive mastic material;
- a discharge manifold in operable communication with said discharge end of said pump and adapted for being pulled across a roofing surface;
- at least one dispensing port positioned on said discharge manifold for discharging the adhesive mastic material onto the roofing surface; and
- a support member operably interconnected to said frame and adapted for holding a roll of roofing material in a downstream position from said discharge manifold, wherein the roofing material can be applied to the roofing surface over the adhesive mastic material while the apparatus is being pulled along the roofing surface.
- FIG. 1 is a front perspective view of the present invention in use;
- FIG. 2 is a front perspective view of the invention shown in FIG. 1 and providing more detail with regard to a discharge manifold and spreader bar;
- FIG. 3 is a front elevation view of the invention shown in FIG. 1;
- FIG. 4 is a right elevation view of the invention shown in FIG. 1;
- FIG. 5 is a front perspective view of the invention shown in FIG. 1, and further identifying a support member used to hold a roll of bulk roofing material; and
- FIG. 6 is a right elevation view of an alternative embodiment of the invention shown in FIG. 1, and identifying the use of a handheld wand for selective application of the adhesive mastic material.
- Referring now to the drawings, FIGS.1-6 are provided herein to more accurately describe the present invention and the components associated therein. Referring now to FIG. 1, a front perspective view of the present invention is provided and which generally shows the numerous components of the device and the position of an operator during use. More specifically, the portable mastic applicator 2 is generally comprised of a
frame 4 which is typically constructed of a metal or other substantially rigid material and which has aplatform 6 interconnected on a lower end. The substantiallyplanar platform 6 is designed to support anadhesive container 14 such as a five gallon pail or other portable device. Theadhesive container 14 is operably positioned below apump 8, which is driven by pneumatic pressure in one embodiment, and thus interconnected to apneumatic injection line 26. For operational purposes, a compressor (not shown) is used to provide the compressed air for thepneumatic injection line 26. Alternatively, the pump may be driven by a gas or electric powered motion. - As discussed herein, the term “adhesive mastic” refers to any type of viscous material such as glues, adhesions, coatings, paints, sealants and other similar materials which may be applied in bulk. Thus, it is anticipated that the present invention may be utilized to disperse materials having a viscosity of between about 120,000 centipoise (“cp”) and 10,000 cp at a temperature of between about 40° F. and 100° F. For applications in the roofing industry, mastic materials such as MBR adhesive and per mastic adhesive may be dispensed from the apparatus, and which generally have a viscosity of between about 11,000 cp and 20,000 cp.
- The
discharge port 20 preferably has a cross-sectional area of at least about 0.50 in2 to provide a sufficient opening to dispense an adequate amount of adhesive mastic material. In a typical application, the mastic material is applied to a thickness of between about ⅙ inches and ⅛ inches to the roofing surface. Thus, thepump 8 of the present invention is typically required to provide a discharge rate of at least about 1 to 2½ gallons per minute (gpm) to provide a sufficient amount of adhesive mastic through the discharge port, which preferably has a length of between 24 inches and 60 inches. - The
pump 8 generally has apump suction end 10, which is in operable communication with the mastic material contained in theadhesive container 14. Thepump 8 further comprises apump discharge end 12 which is interconnected to a downstream line for transporting the mastic material to adischarge manifold 18. This line maybe comprised of screwed metallic pipe and/or high pressure pneumatic line which is commonly known in the art. To selectively interrupt communication from thepump discharge end 12 to thedischarge manifold 18, one ormore valves 24 are provided as shown. - Furthermore, although in a preferred embodiment the
pump 8 is positioned above themastic container 14, it is feasible that the pump could be positioned below theplatform 6 and associatedmastic container 14. Thus, the respective positioning of thepump 8 andmastic container 14 is not critical to the present invention as long as there is communication between themastic container 14 and thepump suction 10. - Positioned on the distal end of the discharge line, a discharge manifold is provided and is shown in greater detail in FIG. 2. The
discharge manifold 18 in one embodiment comprises a metallic pipe or rectangular shaped mechanism with one ormore dispensing ports 20 which extend substantially from one end of thedischarge manifold 18 to the opposing end. Alternatively, one or more individual dispensing ports may be utilized, and which may or may not have individual valves associated therewith to selectively control the amount and position of mastic being dispensed (not shown). Thedischarge manifold 18 is interconnected to the frame by a handle mechanism 42 which has ahinge 40 positioned proximate to thewheels 16, and allows thedischarge manifold 18 to be selectively raised and lowered by the operator as necessary. As further identified, in FIG. 2, one ormore wheels 16 are generally interconnected to a lower portion of theframe 4, and which allows the apparatus to be easily moved from one position to another at a rate of speed determined by the operator. - Referring now to FIG. 3 and FIG. 4, a front elevation view and a right elevation view of the present invention is provided herein respectively. As depicted, the
pneumatic injection line 26 is in communication with apressure gauge 32, and has a secondary line extending to acontainer inductor plate 34. Thecontainer inductor plate 34 has an exterior diameter which is operably sized to fit the internal diameter of theadhesive container 14, and which provides a sealing mechanism to assure the communication of the roofing mastic material from theadhesive container 14 through thepump 8 and the discharge line to the discharge manifold. To assist in removing theinduction plate 34 from thecontainer 14, avalve 24 is closed preventing air intake to thepump 8, and allowing compressed air to be injected into thecontainer 14, which provides an upward force which pushes the inductor plate upward from the container opening. Apressure relief valve 36 is also provided on theinductor plate 36 to release pressure in the container as necessary, and is also opened to allow air to escape as theinductor plate 34 is positioned within thecontainer 14. - As additionally seen in FIGS. 4, a
hinge mechanism 40 may be provided between theframe 4 and thedischarge manifold 18, which can be moved to selectively put the discharge manifold in a downward position as shown, or elevated to allow transportation of the apparatus. Thus, in one embodiment of the present invention, one portion of theframe 4 is used to support theplatform 6,wheels 16,pump 8 and other associated componentry, while another portion of theframe 4 is used to selectively raise and lower thedischarge manifold 18. - As additionally seen in FIG. 2, in one embodiment of the present invention a
spreader 28 is provided which selectively spreads the adhesive mastic material along a roofing surface as the apparatus is rolled. In an alternative embodiment to the present invention, an oscillating device may be used to oscillate thespreader 28 in a direction substantially parallel to the longitudinal access of thedischarge manifold 18 to more effectively and uniformly apply the mastic material to the roofing surface. In one embodiment of the present invention, thespreader 28 is comprised of a rubber material, although other similar materials including fiberglass, metal, and plastic may be used for the same purpose. Alternatively, one or more chains may be used to apply the mastic material in a substantially uniform pattern over a roofing surface. - Referring now to FIG. 5, another embodiment of the present invention is provided herein. More specifically, a
support member 22 is interconnected to theframe 4 in a manner which positions thesupport member 22 immediately downstream of the portable mastic applicator 2. In this embodiment, a roll ofbulk roofing material 38 such as felt is removably interconnected to thesupport member 22, in such a manner which allows thebulk roofing material 38 to unwind and be applied to the roofing surface. In this embodiment, as the mastic adhesive is applied through thedischarge manifold 18 and spread with thespreader 28 while thebulk roofing material 38 is layed down uniformly on top of the mastic material. This embodiment allows both themastic material 38 and roofing material to be applied to the roofing surface simultaneously, and hence saves manpower, time and installment costs. In an alternative embodiment, a bulk granular container may be installed on thesupport member 22 or associatedframe 4, which allows granular material such as mineral granules, gravel, or other materials to be applied to the roofing surface downstream of thedischarge manifold 18. - Thus, the present invention is adapted for a variety of uses to either independently apply a roofing mastic material, or can be used in combination with
bulk roofing materials 38 such as felt or cap sheets, or alternatively with bulk roofing materials such as pea gravel, sand or other materials to a roofing surface. As appreciated by one skilled in the art, the present invention maybe used to either independently apply the mastic material, bulk roofing material such as felt or granular material such as gravel, or alternatively may be used to apply all three simultaneously. - Referring now to FIG. 6, an alternative embodiment of the present invention is provided wherein a handheld wand is provided for use by the operator to selectively apply a single bead of mastic material in a desired location. By closing the
valve 24, the flow of adhesive mastic material to thedischarge manifold 18 is prevented, while anadditional valve 24 is opened, and thus allowing the mastic material to be discharged through thehandheld wand 30 in a predetermined location for use along seams, corners, and other hard to reach locations where the adhesive mastic material is required. When not in use, thehandheld wand 30 and associated hose may be disconnected from the apparatus or stored in an unobstructed position. - In a further embodiment of the present invention not shown, a self contained motor may be utilized in conjunction with the present invention to allow the apparatus to be self propelled. In this embodiment, a small electric, gas operated, or pneumatic motor may be interconnected to the frame with a gearing mechanism and associated chain or belt to drive the wheels at a predetermined speed as determined by the operator. This feature may allow for a larger sized
adhesive container 14 to be used in a range of 10 to 50 gallons, or allow heavierroofing bulk materials 38 to be suspended from thesupport frame 4 while providing ease of operation and reduced fatigue for the operator. - To provide clarity to the present invention, a detailed list of the following components and the associated numbering therein is provided for reference purposes.
# Component 2 Portable Mastic Applicator 4 Frame 6 Platform 8 Pump 10 Pump Suction End 12 Pump Discharge End 14 Adhesive Container 16 Wheels 18 Discharge Manifold 20 Dispensing Port 22 Support Member 24 Valve 26 Pneumatic Injection Line 28 Spreader 30 Handheld Wand 32 Pressure Gauge 34 Container Inductor Plate 36 Pressure Relief Valve 38 Bulk Roofing Material 40 Hinge 42 Handle Mechanism - While various embodiments of the present invention have been described in detail, it is apparent that modifications and adaptations of those embodiments will occur to those skilled in the art. However, it is to be expressly understood that such modifications and adaptations are within the spirit and scope of the present invention, as set forth in the following claims.
