Definitions
- the present invention relates to roof shingle peelers and, more specifically, to a method and apparatus for systematically removing shingles and nails from a roof deck.
- the first category is the roof shingle peeler that is operated manually.
- This manual roof shingle peeler is typically the approximate size of a shovel and has serrations at the leading edge of the shovel for prying the roofing nails from the plywood boards, thereby, detaching the shingles from the roof.
- Such manual roof shingle peelers include U.S. Pat. No. 5,001,946 entitled “Roof Shingle Stripping Apparatus”; U.S. Pat. No. 5,819,603 entitled “Roof Shingle Remover”; and U.S. Pat. No. 6,257,094 entitled “ roofing Shingle And Tar Paper Stripper”. There is even U.S. Pat. No.
- motor driven roof shingle peelers are larger than their manual counterparts and typically powered to simulate the manual operation or include vibrating or oscillating front teeth with shearing type drives to remove the shingle and nails from the roof.
- motor driven roof shingle peelers include U.S. Pat. No. 4,091,535 entitled “Shingle Stripper”; U.S. Pat. No. 4,691,439 entitled “Powered Roof Shingle Detacher And Stripper”; U.S. Pat. No. 5,009,131 entitled “Roof Shingle Stripper Apparatus”; U.S. Pat. No.
- This device however, has several inherent shortcomings.
- First, the entire system uses complex moving parts which are expensive and provide maintenance problems. This is exemplified by the gears, dual pulley, cable, and shaft arrangement, the reciprocating plurality of cutters, and the use of the internal combustion engine to move the pulleys and cables and turn the shafts.
- U.S. Pat. No. 5,098,165 to Jacobs entitled “Guided Roofing Materials Removal Apparatus” discloses a guide system which secures the shingle removal device and the operator in position on an inclined roof so that the roof can be traversed at various positions along different travel paths while being supported.

Description
- This U.S. Patent Application is a divisional of prior U.S. patent application Ser. No. 10/894,912, entitled “Apparatus For Removing Shingles From A Roof”, filed on Jul. 20, 2004, still pending.
- The present invention relates to roof shingle peelers and, more specifically, to a method and apparatus for systematically removing shingles and nails from a roof deck.
- There are generally two categories of roof shingle peelers. The first category is the roof shingle peeler that is operated manually. This manual roof shingle peeler is typically the approximate size of a shovel and has serrations at the leading edge of the shovel for prying the roofing nails from the plywood boards, thereby, detaching the shingles from the roof. Such manual roof shingle peelers include U.S. Pat. No. 5,001,946 entitled “Roof Shingle Stripping Apparatus”; U.S. Pat. No. 5,819,603 entitled “Roof Shingle Remover”; and U.S. Pat. No. 6,257,094 entitled “Roofing Shingle And Tar Paper Stripper”. There is even U.S. Pat. No. 5,918,439 entitled “Roof Shingle Replacement Tool and Method” which discloses a device to install shingles on generally flat roof surfaces. The problem with these manual shingle peelers is that removing all the shingles and nails from a roof deck (e.g. for a condominium, town home, house, etc. . . .) to install a new roof becomes a laborious, physically demanding effort that can span the course of many hours or days while further increasing the opportunity for fatigue and injury to the workers.
- Recognizing this problem created the need for a more automated roof shingle peeler. This formed the second category of motor driven roof shingle peelers. These motor driven roof shingle peelers are larger than their manual counterparts and typically powered to simulate the manual operation or include vibrating or oscillating front teeth with shearing type drives to remove the shingle and nails from the roof. Such motor driven roof shingle peelers include U.S. Pat. No. 4,091,535 entitled “Shingle Stripper”; U.S. Pat. No. 4,691,439 entitled “Powered Roof Shingle Detacher And Stripper”; U.S. Pat. No. 5,009,131 entitled “Roof Shingle Stripper Apparatus”; U.S. Pat. No. 5,098,165 to Jacobs entitled “Guided Roofing Materials Removal Apparatus”; U.S. Pat. No. 5,218,766 entitled “Roofing Removal Apparatus”; and U.S. Pat. No. 5,800,021 entitled “Shingle Remover And Method Of Removing”.
- The most relevant is U.S. Pat. No. 4,091,535 to Lehrter entitled “Shingle Stripper.” This patent discloses a guide device removably affixed to a roof that includes a cable extending between the ridge and the gutter edge of the roof. An internal combustion engine is mounted in a housing having an open forward end and a closed rear end. The engine is coupled to two drive shafts and a cable for moving the housing up the roof along the guide device from the gutter to the ridge. As the housing moves up the roof, cutters in the forward end of the housing, consisting of a first and second plurality of spaced reciprocating teeth, cut the nails of the shingles such that the shingles severed from the roof fall into and accumulate in the rear of the housing for later removal.
- This device, however, has several inherent shortcomings. First, the entire system uses complex moving parts which are expensive and provide maintenance problems. This is exemplified by the gears, dual pulley, cable, and shaft arrangement, the reciprocating plurality of cutters, and the use of the internal combustion engine to move the pulleys and cables and turn the shafts. Second, due to the complexity of the system, the use of the system is limited as it is bulky, slow and too heavy. Third, although the cutters cut the nails to sever the shingles from the roof, the shingles themselves remain intact. As the device moves up the roof, this creates problems as a portion of the shingle may be severed from the roof in front of the device while the remaining portion of the shingle, not located within the front of the device, may still remain affixed to the roof causing pressure or other tension upon the system. It also requires a larger housing to collect the shingles which may likewise impede the use of the device on steep and long roofs due to the increased weight of the full shingles. Lastly, this patent does not disclose or teach the method and apparatus for removing shingles using Applicant's invention.
- Likewise U.S. Pat. No. 5,098,165 to Jacobs entitled “Guided Roofing Materials Removal Apparatus” discloses a guide system which secures the shingle removal device and the operator in position on an inclined roof so that the roof can be traversed at various positions along different travel paths while being supported. The problem with this device is that it: (a) is designed solely as a guide and support member for the operator and the shingle removal device, and (b) continues to require an operator to operate the shingle removal device.
- Thus, there is a need and there has never been disclosed Applicant's unique method and apparatus for removing shingles from a roof deck.
- It is the primary object of the present invention to systematically remove shingles from a roof deck using a roof shingle peeler device. A related object of the present invention is to provide a saw blade operated by a motor and a wedge coacting to remove nails and shingles from the roof deck.
- Another object of the present invention is to provide a horizontal arm and skiis to regulate the depth of the wedge and saw blade for removing and cutting the shingles.
- Another object of the present invention is to provide a duct to transport the shingles into a bag for receiving and collecting all the shingles removed from the roof deck.
- Another object of the present invention is to provide a hoist and return hoist enabling the roof shingle peeler device to traverse the roof deck from the base to the crest of the roof deck.
- Still another object of the invention is to provide a roof shingle device that is safe and easy to use.
- Other objects of the present invention will become more apparent to persons having ordinary skill in the art to which the present invention pertains from the following description taken in conjunction with the accompanying drawings.
- The present invention is a roof shingle peeler device which comprises a saw blade, a motor to operate the saw blade, a horizontal arm and skiis to regulate the depth of the wedge, the wedge removing the nails and shingles from the roof deck and enabling the saw blade to cut the shingles into a predefined section, and a frame to facilitate the transportation of the predefined section of shingles for being received and collected into a bag for disposal.

FIG. 1 , there is illustrated a roofshingle peeler device 30 situated on aroof deck 32 which is covered byshingles 34. Theroof deck 32 is typically used for a house, town home, condominium, etc. Alternatively, theroof deck 32 may be used in connection with any type of dwelling, abode, storage, or any other type of building or facility that requires the use of a roof. Theroof deck 32, based upon its design, forms aroof angle 36. Theroof deck 32 is covered by a layer of a protective sheet 33 (FIG. 3 ) and then by a layer of the shingles 3.4. Theshingles 34 are installed lengthwise into rows along theroof deck 32 from the base 44 to thecrest 46. Nails 50 (FIG. 3 ) are used to secure both theprotective sheet 33 and theshingles 34 to theroof deck 32. Atypical shingle 34 has a length of substantially thirty-six inches (36″) and a shingle thickness 35 (FIG. 3 ) of substantially one-eighth of an inch (⅛″). Theprotective sheet 33 and theshingles 34 coact to protect theroof deck 32 against adverse weather and to prevent leaks or other problems that may be caused by the elements. - A hoist 38, operated by a
roofer 40 standing on aplatform 42, pulls the roofshingle peeler device 30 up theroof deck 32 from the base 44 to thecrest 46. Preferably, the hoist 38 uses acable 48 to pull the roofshingle peeler device 30 up theroof deck 32. As the roofshingle peeler device 30 is being pulled up theroof deck 32, the roofshingle peeler device 30 removes thenails 50 and cuts theshingles 34 on theroof deck 32 into a predefined section ofshingles 34. The removed nails 50 and the predefined section ofshingles 34 removed from theroof deck 32 are then collected in abag 52. After the roofshingle peeler device 30 reaches thecrest 46 of theroof deck 32, a return hoist 54 uses areturn cable 56 to pull the roofshingle peeler device 30 back down to the base 44 of theroof deck 32 where the roofshingle peeler device 30 originally started. This is referred to as a “strip run.” The roofshingle peeler device 30 is then repositioned lengthwise along the base 44 of theroof deck 32, below another portion ofshingles 34, and the process is repeated. This process continues until all of theshingles 34 and thenails 50 are removed from theroof deck 32. During this process, the hoist 38 is provided with ashield 58 to protect theroofer 40 from any loose debris or other material that may be projected from theroof deck 32 while the roofshingle peeler device 30 is in use. Preferably, theshield 58 is a transparent, plastic protective shield capable of resisting .22 caliber bullets. Such a transparent, plastic protective shield is made by Lexan. - Applicant's four embodiments for its roof
shingle peeler device 30 and how each embodiment removes the shingles and nails from the roof is described in further detail below. - Turning to
FIG. 2 , the first embodiment of Applicant's roofshingle peeler device 30 is more clearly depicted. This embodiment is referred to herein as the “original or first embodiment.” Theshingle peeler device 30 consists of asaw blade 60. The purpose of thesaw blade 60 is to cut theshingles 34 intopredefined sections 76 for removal from theroof deck 32. Thesaw blade 60 is situated in a vertical position relative to the horizontal orflat shingles 34 nailed to theroof deck 32. This perpendicular relationship permits thesaw blade 60 to make a clean cut through theshingles 34. As discussed in more detail below, in cutting theshingles 34, thesaw blade 60 cuts through the shingle thickness 35 (FIG. 3 ) of theshingles 34 but does penetrate into theroof deck 32, thereby, preserving theroof deck 32 for the installation of a replacement set ofshingles 34. In the preferred embodiment, thesaw blade 60 is made of steel and is fourteen inches (14″) in diameter. Alternatively, thesaw blade 60 may be of any size provided that it is sufficient to cut through theshingles 34. - The
saw blade 60 is operated by amotor 61. In the preferred embodiment, themotor 61 is an off the shelf, direct drive, three and one-half horsepower, fifteen amp motor. Alternatively, themotor 61 may be any size or horsepower provided there is sufficient power generated by the motor to permit thesaw blade 60 to cut through theshingles 34. - The
saw blade 60 is aligned and positioned between two parallel supportingbrackets 62. The supportingbrackets 62 are attached to awedge 66 and aframe 68, at one end, and to ahorizontal arm 64, at the other. - The
wedge 66 is an elongated member that extends awidth 86 in front of theframe 68 and continues awidth 88 beyond the front of the frame 68 (see alsoFIG. 7 ). In the preferred embodiment, thewidth 86 is substantially equal towidth 88 and thesaw blade 60 is positioned in the center of thewedge 66 and at the right side of the frame 68 (see alsoFIG. 7 ). Alternatively, this unit of the roof shingle peeler device 30 (i.e., thesaw blade 60,motor 61, supportingbrackets 62,horizontal arm 64, and wedge 66) may be likewise positioned on the left side of theframe 68 as depicted in phantom inFIG. 7 . In either of these locations for the roofshingle peeler device 30, themotor 61 is positioned on the opposite side of thesaw blade 60 from theframe 68. The reason that themotor 61 is positioned in this manner is so that the weight of themotor 61 will counter balance the weight of theframe 68 and thereby provide a more stabilized device with the weight of the device being centrally located at thesaw blade 60. - The
wedge 66 has aleading edge 78 and a trailingedge 80 which are separated byteeth 82. Theteeth 82 are equally spaced from one another andform channels 84 between them. At the leadingedge 78, thewedge 66, when in use, is inserted under theshingles 34 such that theteeth 82 abut against theroof deck 32. Theteeth 82 then gradually taper, along the vertical axis, upwardly or at an incline from theroof deck 32 to the trailingedge 80 and, along the horizontal axis, theteeth 82 extend equi-distant from one another from the leadingedge 78 to the trailingedge 80 as further illustrated inFIG. 7 . In the preferred embodiment, thewedge 66 is made of steel or metal. Alternatively, thewedge 66 may be made of any material provided that the material is of sufficient strength and durability for its intended purpose. - The purpose of the
wedge 66 is to remove thenails 50 from theroof deck 32 and lift theshingles 34 into a position to be cut by thesaw blade 60. To accomplish this, the leadingedge 78 of thewedge 66 traverses theroof deck 32 from the base 44 to thecrest 46. With respect to thenails 50, while traversing theroof deck 32, either: the leadingedge 78 of theteeth 82 engages and forces thenails 50 into thechannels 84 to be removed from theroof deck 32, and/or thenails 50 are directly received into thechannels 84 and lifted from theroof deck 32 by the adjoiningteeth 82 as theteeth 82 extend from the leadingedge 78 to the trailingedge 80. - With respect to the
shingles 34, the leadingedge 78 of thewedge 66, while in use, is burrowed between theroof deck 32 and theshingles 34. As thewedge 66 proceeds up theroof deck 32, theshingles 34 traverse over the top surface of theteeth 82. As theteeth 82 incline or taper upwardly from the leadingedge 78 to the trailingedge 80, theshingles 34 are lifted by thewedge 66 from theroof deck 32. Additionally, nails 50 that remain attached to theshingles 34 are removed from theroof deck 32 along with theshingles 34. The liftedshingles 34 are then cut into thepredefined section 76 by thesaw blade 60 and received into theframe 68. - The
frame 68 is preferably a hollow, rectangular member that has aframe height 90 and a frame width 92 (see alsoFIG. 7 ). Theframe height 90 is of sufficient size to accommodate theshingle thickness 35 of all theshingles 34 in thepredefined section 76. Theframe width 92 is of sufficient size to accommodate the width of the entirepredefined section 76. Theframe height 90, theframe width 92, and length of theframe 68 form aduct 94. As illustrated and inFIGS. 4 through 6 , theduct 94 provides an opening in theframe 68 to receive all theshingles 34 in thepredefined section 76 and facilitate the easy transportation of thepredefined section 76 ofshingles 34 into thebag 52. Thebag 52 is securely attached around the exterior circumference of theframe 68 bylatches 96. The purpose of thebag 52 is to receive, collect, and facilitate the easy disposal of thepredefined sections 76 ofshingles 34 andnails 50 removed from theroof deck 32. To accomplish this, thebag 52 must be of sufficient strength and durability to avoid tearing due to the generally rigid nature of theshingles 34, the sharp edges of theshingles 34, and/or the full weight of thepredefined section 76 ofshingles 34 collected. In the preferred embodiment, thebag 52 is a standard grade, three milliliter (3 mil.), forty-two gallon (42 gal.) contractor bag. Alternatively, the roofshingle peeler device 30 may be used without theframe 68 and thebag 52. In this instance, the roofshingle peeler device 30 will operate as described herein except that thepredefined sections 76 ofshingles 34 cut from theroof deck 32 will remain loose on theroof deck 32 until manually bagged and discarded by the users. - The
horizontal arm 64 extends outwardly adistance 98 from the supportingbrackets 62 terminating inskiis 70. The purpose of thehorizontal arm 64 is twofold: (1) to provide appropriate leverage in pulling the roofshingle peeler device 30 up theroof deck 32, and (2) enable thewedge 66 and thesaw blade 60 to be positioned relative to theroof deck 32 andshingles 34 such that thesaw blade 60 can cut and separate thepredefined section 76 from the remainingshingles 34 and do so without damaging theroof deck 32. The appropriate leverage is accomplished by providing theproper distance 98. In the preferred embodiment, thedistance 98 is substantially twenty inches (20″). Thehorizontal arm 64 is also positioned such that the vertical centerline of thehorizontal arm 64 corresponds to the vertical centerline of thesaw blade 60. The positioning of thesaw blade 60 relative to theroof deck 32 andshingles 34 is accomplished by the combination ofdistance 98 of thehorizontal arm 64 and theskiis 70. Thehorizontal arm 64 and theskiis 70 are preferably made of steel or metal. - The
skiis 70 are attached to thehorizontal arm 64 by threadedscrews 72 and corresponding fasteners 74 located on both sides of thehorizontal arm 64. In this manner, if thehorizontal arm 64 is desired to be raised higher (i.e., raise thesaw blade 60 in relation to theshingles 34 and roof deck 32), the fasteners 74 on the top side of thehorizontal arm 64 are raised to the desired height, thehorizontal arm 64 is correspondingly lifted to that height, and the fasteners 74 located on the underside of thehorizontal arm 64 are likewise raised to secure thehorizontal arm 64 into that desired height. If, on the other hand, thehorizontal arm 64 is desired to be lowered (i.e., lower thesaw blade 60 more into theshingles 34 and closer to the roof deck 32), the opposite occurs. The fasteners 74 located on the underside of thehorizontal arm 64 are lowered to the desired height, thehorizontal arm 64 is correspondingly lowered to that height, and the fasteners 74 located on the top side of thehorizontal arm 64 are then lowered to secure thehorizontal arm 64 into that desired height. - The purpose of the
skiis 70 is to control and stabilize thecable 48 located between them thereby reducing the yaw of thecable 48. The fasteners 74 are each provided with sleeves (not illustrated) to assist in securing thecable 48 between theskiis 70. Preferably, the sleeves are made of brass which is less abrasive on thecable 48. - The
skiis 70 also haveski tips 116 which permit theskiis 70 to easily traverse over theroof deck 32 without getting hooked or caught in theshingles 34 or in any other manner inhibiting the forward motion of the device. - Alternatively, in lieu of using the
skiis 70, it is contemplated that wheels or any other adjustable means may be used. The adjustable means should also sufficiently support thehorizontal arm 64 and traverse the roof deck with minimal friction or difficulty. -
FIGS. 4 , 5, and 6 depict the roofshingle peeler device 30 traversing theroof deck 32 from the base 44 to thecrest 46. As previously discussed, thepredefined section 76 of theshingles 34 are collected in thebag 52. With respect to theshingles 34 that are adjacent to thepredefined section 76 and outside theframe 68, as the roofshingle peeler device 30 traverses theroof deck 32, thewidth 88 of thewedge 66 removes thenails 50 from theshingles 34 that it is under. As a result, when the roofshingle peeler device 30 is repositioned to remove the next set ofpredefined section 76 ofshingles 34 from theroof deck 32, theseadjacent shingles 34, with removednails 50, will form the left portion of the next set ofpredefined section 76 of shingles to be removed. In this manner, as thenails 50 have already been removed from the next set ofpredefined section 76 ofshingles 34, thewidth 86 of thewedge 66 will be directed to the remainder of thenails 50 andshingles 34 in thatpredefined section 76 for removal and collection into thebag 52. - The return hoist 54 enables the roof
shingle peeler device 30 to be pulled back down theroof deck 32, from thecrest 46 to the base 44, to where the roofshingle peeler device 30 originally started. The roofshingle peeler device 30 and the return hoist 54 are then correspondingly repositioned along theroof deck 32 to the right. Alternatively, if the unit was affixed to the left side of theframe 68, the roofshingle peeler device 30 would remove theshingles 34 from theroof deck 32 in the opposite direction starting on the right edge of theroof deck 32 and repositioning left along theroof deck 32 until all theshingles 34 have been removed. - As more clearly illustrated in
FIG. 6 , the return hoist 54 consists of amotor 100 secured to ahousing 102 by aclamp 104. Adrive shaft 106 extends outwardly from themotor 100 and attaches to aspool 108 containing thereturn cable 56. Thespool 108 is likewise attached to thehousing 102 by abar 110. Thehousing 102 providesblades 112 to insert between theshingles 34 and theroof deck 32, thereby, securing the return hoist 54 in position while the roofshingle peeler device 30 is in use during a strip run. When the roofshingle peeler device 30 traverses from the base 44 to thecrest 46 of theroof deck 32, thespool 108 of the return hoist 54 permits thereturn cable 56, which is attached to the roofshingle peeler device 30 as illustrated inFIG. 12 , to follow the roofshingle peeler device 30 to thecrest 46. Preferably, thereturn cable 56 is in the same vertical centerline of thesaw blade 60. When the roofshingle peeler device 30 is ready to be returned to the base 44 for repositioning, themotor 100 is activated to rotate thedrive shaft 106 and pull the roofshingle peeler device 30 back to the base 44 of theroof deck 32. In the preferred embodiment, themotor 100 is at least a 9 amp, variable speed, reverse alternating current (AC) or direct current (DC) motor. - Turning to
FIG. 8 , the second embodiment of Applicant's roofshingle peeler device 30 is more clearly depicted. This embodiment is referred to herein as the “second embodiment.” There are four differences between this embodiment and the original embodiment. First, thehorizontal arm 64 is positioned directly in the center of theframe 68. Second, the parallel supportingbrackets 62 have been replaced with asquare frame 114. Third, although thehorizontal arm 64 has been relocated, thesaw blade 60 remains, as illustrated here, on the right side of theframe 68. With the unit located on the right side of theframe 68, themotor 61 is now repositioned on the left side of thesaw blade 60. This is opposite to where themotor 61 is located in the original embodiment. Lastly, theentire wedge 66 is placed directly in front of theframe 68. In this second embodiment, the roof shingle peeler device is simpler and more stabilized. - The
horizontal arm 64 and theskiis 70 remain the same as disclosed in the original embodiment. Thesquare frame 114, illustrated in more detail inFIG. 9 , provides two parallel front bars 118 each connected to two opposed side bars 120. Thefront bars 118 are separated from one another by afront bar distance 122. In the preferred embodiment, thefront bar distance 122 is substantially four and one-half inches (4 ½″). Thefront bars 118 each have a bore (not illustrated) centrally located for receiving and retaining thehorizontal arm 64. As a result, the parallelfront bars 118 provide increased support and stability to the device thereby inhibiting the yaw, pitch, and/or torque that may be experienced or created by thehorizontal arm 64 as it traverses theroof deck 32. - The
wedge 66 is the same wedge as disclosed in the original embodiment. In the second embodiment, theentire width wedge 66 is located along theframe width 92. With thewedge 66 as positioned, the roofshingle peeler device 30 will remove theshingles 34 into a largerpredefined section 76 than in the original embodiment. Preferably, the second embodiment, in operation as illustrated inFIG. 10 , will remove apredefined section 76 that is substantially twice as large as thepredefined section 76 in the original embodiment and require approximately half as many strip runs. - The
square frame 114 is also provided with an L-shaped support member 124 (FIG. 8 ). The L-shapedsupport member 124 is used to secure thesaw blade 60 andmotor 61 into position on either the right or the left side of thesquare frame 114. As theskiis 70, thehorizontal arm 64, and thesquare frame 114 are all centered in relation to thewedge 66 andframe 68, themotor 61 is positioned on the inside of thesaw blade 60 within thesquare frame 114. This assists in centralizing the weight of themotor 61 with the entire device and in creating a more stabilized device. - The
wedge 66, theframe 68,duct 94, andbag 52 are the same, in this second embodiment, as that disclosed in the original embodiment. -
FIG. 11 more clearly illustrates the attachment of thebag 52 to theframe 68. Theframe 68 provides arectangular ledge 130, located on the opposite side of thewedge 66, around the exterior circumference of theframe 68. Therectangular ledge 130 is positioned aborder distance 134 from the outermost exterior edge of theframe 68 and extends outwardly from the frame 68 aledge thickness 132. In the preferred embodiment, theborder distance 134 is substantially equal to theledge thickness 132. As a result, this forms auniform ridge 136 around the exterior circumference of theframe 68. As discussed previously, thebag 52 is folded around the exterior circumference of theframe 68 and theledge 130. Arectangular holder 126 having fourrigid sides 128 of auniform holder thickness 138 and forming a hollow center is inserted over the exterior of the bag and into theridge 136. As theholder thickness 138 of therectangular holder 126 is substantially equal to theledge thickness 132 andborder distance 134, thebag 52 becomes secured between therectangular holder 126, theledge 130, and theframe 68 which are each flush with one another and providing an equal and opposite force for securing thebag 52 between them. Thelatches 96 haveclaws 140 that frictionally grip theframe 68 to secure theholder 126 to theframe 68. - In
FIG. 12 , the attachment of the hoistcable 48 and thereturn cable 56 of the return hoist 54 to the roofshingle peeler device 30 are more clearly illustrated. The hoistcable 48 extends from the hoist 38, between theskiis 70, and attaches to thehorizontal arm 64 between the front bars 118. In the preferred embodiment, the hoistcable 48 is formed into aloop 142 which is secured to thehorizontal arm 64 by abolt 144. Alternatively, it is contemplated that any other means that is known in the art may be used to secure the hoistcable 48 to thehorizontal arm 64. Thebolt 144 has aflat bottom 146 that, upon tightening thebolt 144, holds the hoistcable 48 to thehorizontal arm 64. The hoistcable 48 is also attached in this location such that theskiis 70 andhorizontal arm 64 can be sufficiently pulled into the hoist 38 for enabling the roofshingle peeler device 30 to cut thepredefined section 76 ofshingles 34 all the way up to thecrest 46 of theroof deck 32. - The
return cable 56 also has aloop 148 formed into its end. Theloop 148 is attached to ahandle 150. Preferably, thehandle 150 forms aring 154 and utilizes alatch 156 for opening and closing thering 154 to receive theloop 148 of thereturn cable 56. Thering 154 also receives afinger loop 152 on thewedge 66. In this manner, thereturn cable 56 is secured to the roofshingle peeler device 30. Alternatively, it is contemplated that any other means may be used to secure thereturn cable 56 to the roofshingle peeler device 30 provided that this alternate securing means is of sufficient strength for the return hoist 54 to pull the roofshingle peeler device 30 back down theroof deck 32 from thecrest 46 to the base 44. - Turning to
FIG. 13 , the third embodiment of Applicant's roofshingle peeler device 30 is more clearly depicted. This embodiment is referred to herein as the “third embodiment.” In this third embodiment, thesaw blade 60, the supportingbrackets 62, thewedge 66, thehorizontal arm 64, theskiis 70, andbag 52 are all the same as that disclosed in the original and/or second embodiments. The roofshingle peeler device 30 also uses the same hoist 38 and return hoist 54 for traversing theroof deck 32. - The roof
shingle peeler device 30 does, however, comprise a belt drive orpulley motor assembly 160 to operate thesaw blade 60. In the preferred embodiment, thepulley motor assembly 160 includes amotor 162 that is a 15 amp, 3 ½ horsepower electric alternating current (AC) or gas motor. Themotor 162 is also energized by 110 volts. As this is the same voltage that is provided by a typical house electrical outlet, thepulley motor assembly 160 is ideal for use with the roofshingle peeler device 30 as it eliminates the necessity of having to provide a portable electrical generator to run themotor 61 of the original and second embodiments. As illustrated inFIG. 14 , thepulley motor assembly 160 comprises themotor 162, twopulleys 164 connected by a drivingbelt 166, and adrive shaft 168 for engaging thesaw blade 60. Acover 158 is provided for protecting the users from potential injury resulting from thesaw blade 60, especially when in use. - A supporting
bracket 169 having avertical plate 170 is attached to ahorizontal plate 172 of thewedge 66. Thevertical plate 170 is positioned directly behind thesaw blade 60 and thewedge 66. In use, thenails 50 andshingles 34 of theroof deck 32 are removed and cut, as described previously, by the combination of thewedge 66 and sawblade 60. As theshingles 34 proceed beyond thewedge 66 and sawblade 60, theshingles 34 cut by thesaw blade 60 are divided or separated by thevertical plate 170 with theshingles 34 on the left side of thesaw blade 60 being directed by thevertical plate 170 to the left side of thesaw blade 60 and theshingles 34 on the right side of thesaw blade 60 being directed by thevertical plate 170 to the right side of thesaw blade 60. The portion of theshingles 34 that do not engage thevertical plate 170 will otherwise pass over the top of thehorizontal plate 172. As a result, thevertical plate 170 facilitates the division or separation of the cut or removed shingles from the shingles that remain attached to the roof deck and enables the roof shingle peeler device to continue to traverse the roof deck uninhibited by the shingles still attached to the roof deck. - The benefits of this third embodiment are that: (1) the
motor 162 provides a more convenient and efficient motor; (2) in the original and second embodiments, the roof shingle peeler device started to remove shingles from the roof deck from either the left or right side of the roof deck depending upon whether the saw blade was located on the right or left side of the device, respectively. With themotor 162, sawblade 60,wedge 66,horizontal arm 64, and skiis 70 all positioned in the same vertical centerline, the roof shingle peeler device in this third embodiment can start to remove shingles from the roof deck from any location on the roof deck; (3) thevertical plate 170 assists in the division or separation of the shingles and the movement of the device up the roof deck is not restrained or inhibited by the cut or removed shingles or the shingles that remains attached to the roof deck and have yet to be removed; (4) the roof shingle peeler device can operate with or without the bag; and (5) provides a more balanced device. - Turning to
FIG. 15 , the fourth embodiment of Applicant's roofshingle peeler device 30 is more clearly depicted. This embodiment is referred to herein as the “fourth embodiment.” In this fourth embodiment, thesaw blade 60, thehorizontal arm 64, theskiis 70, thesquare frame 114, the side bars 120, thewedge 66, and thebag 52, if used, are all the same as that disclosed in the second embodiment. The roofshingle peeler device 30 also uses the same hoist 38 and return hoist 54 for traversing theroof deck 32. - This fourth embodiment of the roof
shingle peeler device 30, like the third embodiment, comprises a belt drive orpulley motor 160 to operate thesaw blades 60. In the preferred embodiment, thepulley motor 160 is a 15 amp, 3 ½ horsepower electric alternating current (AC) or gas motor which is supported by thesquare frame 114. Thepulley motor 160 is also energized by 110 volts. As this is the same voltage that is provided by a typical house electrical outlet, thepulley motor 160 is ideal for use with the roofshingle peeler device 30 as it eliminates the necessity of having to provide a portable electrical generator to run themotor 61 of the original and second embodiments. As illustrated inFIG. 15 , thepulley motor 160 comprises amotor 162, twopulleys 164 connected by a drivingbelt 166, and adrive shaft 168 for engaging thesaw blades 60. Acover 158 is provided for protecting the users from potential injury resulting from thesaw blades 60, especially when in use. - This fourth embodiment provides two differences over the first three embodiments. First, the device provides
dual saw blades 60, one located on the left side of theframe 68 and the other located on the right side of theframe 68. Thedual saw blades 60 are attached to one another by an axle 240 (FIG. 16 ). Thedual saw blades 60 enable the shingles to be cut on both sides of the predefined section 76 (FIG. 2 ) rather than on just one side as in the first three embodiments. - Second, the
frame 68 is provided with dualvertical flanges 238 on opposite sides of theframe 68 as illustrated inFIG. 16 . The purpose of the dualvertical flanges 238 is to separate thepredefined section 76 of shingles from the shingles that remain attached to theroof deck 32. Thedual flanges 238 each have aflange leading edge 242 and aflange trailing edge 244. In the preferred embodiment, theflange leading edge 242 coincides with the front sides of theframe 68 and the entrance to theduct 94. From theflange leading edge 242, thedual flanges 238 taper outwardly from theframe 68 to theflange trailing edge 244. In this manner, upon thedual saw blades 60 cutting the shingles, thepredefined section 76 of shingles, also referred to in this embodiment as the center section, proceeds along directional line A (FIG. 17 ) straight into theduct 94. The shingles separated from opposite sides of thepredefined section 76 of shingles, also referred to in this embodiment as the left section and the right section, are directed, using the dualvertical flanges 238, along directional line B and around theframe 68 andduct 94. As a result, the roofshingle peeler device 30 is enabled to proceed from the base 44 to thecrest 46 of theroof deck 32 without being inhibited or restricted by the shingles remaining attached to theroof deck 32 and not yet removed. - Thus, the benefits of this fourth embodiment are that: (1) the pulley motor provides a more convenient and efficient motor; (2) in the original and second embodiments, the roof shingle peeler device started to remove shingles from the roof deck from either the left or right side of the roof deck depending upon whether the saw blade was located on the right or left side of the device, respectively. With the pulley motor, wedge, horizontal arm, and skiis all positioned in the same vertical centerline and coacting with the dual saw blades, the roof shingle peeler device in this fourth embodiment can, like the third embodiment, start to remove shingles from the roof deck from any location on the roof deck; (3) the dual saw blades improve upon the third embodiment as this device can cut the shingles simultaneously on both the left and right sides of the roof
shingle peeler device 30; (4) the dual vertical flanges assists in the division or separation of the shingles from the predefined section and also enable the movement of the device traversing up the roof deck without being restrained or inhibited by the shingles that remains attached to the roof deck; (5) the roof shingle peeler device can operate with or without the bag; and (6) provides a more balanced device. -
FIG. 18 more clearly illustrates the hoist 38. The hoist 38 comprises adirectional guide 174,dual arms 176, and theplatform 42. Thedirectional guide 174 anddual arms 176 are connected by a hinge 180 (see alsoFIG. 19 ). Thehinge 180 enables the hoist 38 to accommodate anyroof angle 36 such that thedirectional guide 174 parallels the front side of theroof deck 32 and thedual arms 176 parallel the back side of theroof deck 32 to theplatform 42. A hoist adjustable means 210 (FIG. 20 ) is utilized to secure thedirectional guide 174 and thedual arms 176 of the hoist 38 into this position relative to the front and back sides of theroof deck 32. The hoistadjustable means 210 comprises twoparallel beams 212 separated by aroller 214 which is securely attached to the side of thedirectional guide 174. Preferably, theroller 214 is permitted to slide in either direction between the twoparallel beams 212. As theroller 214 slides between the twoparallel beams 212, thedirectional guide 174 and thedual arms 176 pivot around the hinge 180 (FIG. 19 ) to accommodate theparticular roof angle 36 of theroof deck 32. Upon reaching theparticular roof angle 36 and the desired position of thedirectional guide 174 anddual arms 176 in relation to theroof deck 32, alever 216 attached to theroller 214 is used to tighten the hoist 38 into position. - While the hoist 38 is positioned to accommodate the
roof angle 36, it is also secured to theroof deck 32. An L-bracket 218, attached to eachdual arm 176, andcleats 220, attached to each L-bracket 218, are also used to secure the hoist 38 to theroof deck 32. The L-bracket 218 is preferably welded to eachdual arm 176 and providespockets 222 to retain thecleat 220 to the L-bracket 218. Thepockets 222 also facilitate eachcleat 220 to be inserted directly into theroof deck 32 thereby securing the hoist 38 to theroof deck 32, especially when in use. Preferably, sixcleats 220 per L-bracket 218 on eachdual arm 176 is used. Alternatively, it is contemplated that more orless cleats 220 or any other means may be used to secure the hoist 38 to theroof deck 32 provided the hoist 38 is secured to theroof deck 32 sufficient to pull the roofshingle peeler device 30 up theroof deck 32 as described herein. - Referring back to
FIG. 18 , acontrol box 182 is provided to control the operation of the roofshingle peeler device 30 and the hoist 38. Thecontrol box 182 comprises on/off power control switches 184 and 186. The on/offpower control switch 184 controls the electrical power of the roofshingle peeler device 30. Apower cord 188 provides continuous electrical power source to thecontrol box 182. If the on/offpower control switch 184 is toggled to the off position, the roofshingle peeler device 30 and, in particular, themotor 61 will not be energized and prohibited from operating. If the on/offpower control switch 184 is toggled to the on position, the electrical power supplied from thepower cord 188 will continue through thecontrol box 182 and through amotor cord 190 to permit the operation of themotor 61 and ultimately the roofshingle peeler device 30. Likewise, the on/offpower control switch 186 operates in the same manner as the on/offpower control switch 184 except that the on/offpower control switch 186 controls the operation of the hoist 38. The hoist 38 provides a hoistmotor cord 192 that extends from thecontrol box 182 to a hoistmotor 178 to operate the hoist 38. As the roofer 40 (FIG. 1 ) stands on theplatform 42 to operate the device, thecontrol box 182 is conveniently positioned for access by theroofer 40. Thecontrol box 182 is also more clearly illustrated inFIG. 19 . - The hoist
motor 178 engages, as illustrated inFIG. 20 , a set ofgears 194 for controlling a hoistpulley system 196. The hoistpulley system 196 provides ahousing 202 for the gear drive shafts (not illustrated) and acable drum 198 for encapsulating the hoistcable 48 that is fitted around a hoist pulley 200 (FIG. 21 ). This hoistpulley system 196 is used to pull the roofshingle peeler device 30 from the base 44 to thecrest 46 of theroof deck 32. - As illustrated in
FIGS. 21 through 23 , when the on/offpower control switch 186 is toggled to the on position, the hoist 38 begins to operate. As it begins to operate, the hoistmotor 178 powers the set of gears 194 (FIG. 20 ) which engage the hoistpulley system 196 and begin to rotate thecable drum 198 for turning the hoistcable 48 and, thereby, pulling the roofshingle peeler device 30 up theroof deck 32. As the roofshingle peeler device 30 reaches the hoist 38 being pulled along direction A, the hoist 38 provides a funnelingguide 204 that is fitted with taperedsides 206 to engage theskiis 70 and to redirect, if necessary, theskiis 70 and thehorizontal arm 64 into thedirectional guide 174. In the preferred embodiment, thedirectional guide 174 has aguide width 208 that is slightly larger than the width of thehorizontal arm 64. As a result, upon theskiis 70 andhorizontal arm 64 entering thedirectional guide 174, as illustrated inFIG. 22 , the roofshingle peeler device 30 is positioned within the center of and becomes stabilized within the hoist 38. As illustrated inFIG. 23 , this is facilitated by the hoistpulley 200 and thecable 48 being centered between theskiis 70. Thedirectional guide 174 is also of sufficient length to accommodate thedistance 98 of thehorizontal arm 64 such that the roofshingle peeler device 30 may fully reach thecrest 46 of theroof deck 32 thereby permitting thewedge 66 to completely remove theshingles 34 within thepredefined section 76 all the way up to thecrest 46 of theroof deck 32. - After the
predefined section 76 ofshingles 34 is removed from theroof deck 32 and the roofshingle peeler device 30 is repositioned for the next strip run, the hoist 38 is likewise correspondingly repositioned. To reposition the hoist 38, thecleats 220 must first be removed from theroof deck 32. Then, a stepdown lever 224 (FIGS. 18 and 19 ) is used to lift the hoist 38 from theroof deck 32. Upon depression of abar 226, located on thestepdown lever 224, towards theroof deck 32, the opposite end of thestepdown lever 224 provides an upward force on asecondary hinge 228 attached to the hoist 38. Thesecondary hinge 228 pivots in an upward direction away from theroof deck 32 such that the weight of the hoist 38 transfers to and rests on a set ofwheels 230 attached perpendicularly to thestepdown lever 224. With the weight on thewheels 230 and the hoist 38 no longer attached to theroof deck 32, the hoist 38 can be rolled and repositioned along theroof deck 32 to correspond to the same repositioning of the roofshingle peeler device 30 for the next strip run. A second set ofwheels 232 are attached to a platform support 234 (FIG. 18 ) to permit thedual arms 176 and theplatform 42 to be repositioned as well. Upon repositioning, thestepdown lever 224 is released such that thesecondary hinge 228 pivots towards theroof deck 32 placing the weight of the hoist 28 back on theroof deck 32. Thecleats 220 are then reinserted into theroof deck 32 to again secure the hoist 38 to theroof deck 32. - Thus, there has been provided a unique method and apparatus for removing shingles from a roof. While the invention has been described in conjunction with a specific embodiment, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it in intended to embrace all such alternatives, modifications and variations as fall within the spirit and scope of the appended claims.
