Benefits of technology
[0014] The present invention thus provides a substantial improvement over the shingle cutting devices and methods previously used in the roofing industry. For example, because the shingle cutting device ensures that the same distance between the cut and the center line of the W-valley section will be used in each and every instance where the shingles are being cut, the accuracy and pleasing appearance of each cut is virtually assured. Also, because the present invention may quickly and accurately cut both sides of the W-valley, the efficiency with which the shingles may be cut is greatly increased, thus decreasing the time necessary for the roofer to engage in that activity. Finally, because the shingle cutting device is designed to be constructed as a single unit, the opportunity for mechanical breakdown is greatly reduced, and the durability and longevity of the shingle cutting device is greatly enhanced. It is thus seen that the present invention provides a substantial improvement over those devices and methods found in the prior art.
Problems solved by technology
At each point on the roof where there is a valley, however, the shingle edges must be trimmed into a straight line aligned with the valley to increase the aesthetic appearance of the roof and decrease the likelihood of damage to the roof shingles.
As can be seen, however, there are numerous opportunities for mistakes to be made in the trimming of the shingles when the above-described method is used.
Each of these prior art devices, however, includes similar limitations in that the shingle must be cut prior to its being placed on the roof, and therefore accuracy in the shingle cut is suspect at best and, in a worse case scenario, may result in the shingle having to be discarded when it does not fit properly on the roof surface.
Even those devices which are designed to cut shingles while in place on roofs, such as that described in Conley, U.S. Pat. No. 6,412,382, do not provide simple and efficient devices by which the shingles may be cut, instead providing a cutting device for cutting a single shingle at a time which will not improve the efficiency of the cutting process.

Embodiment Construction
[0023] The shingle cutting device 10 of the present invention is shown best in FIGS. 1 and 4-7 as including a base section 12 which includes an inverted generally C-shaped channel 14 formed on the underside thereof. The inverted, generally C-shaped channel 14 preferably has a base opening and curved walls and is designed to fit over and slidably engage the upwardly extending ridge 72 of a “W”-valley 70 which is used in the valley sections of shingled roofs, as shown best in FIGS. 2 and 3. In the preferred embodiment, the base body or section 12 would have a length of approximately six to ten inches, a width of approximately one to two inches, and a height of approximately one to two inches with the depth of the inverted, generally C-shaped channel 14 being approximately one quarter of an inch to an inch. Mounted on top of base section 12 is a handle 20 which is designed to be grasped by the user of the invention in a comfortable yet power-enhancing position. Specifically, as shown b...

A shingle cutting device for use in roof valleys includes a base body having an upper surface and a lower surface and a handle device mounted on the upper surface. An inverted, generally C-shaped roof valley-engaging guide channel is formed on and extends along the lower surface of the base body, and a blade support arm is mounted on and extends outwards from the base body, the blade support arm having an inner end and an outer end. A blade support device such as a blade clamp is mounted on the blade support arm adjacent the outer end thereof and a shingle cutting blade is removably mounted in the blade support device and extends downwards therefrom, the shingle cutting blade operative to engage and cut shingles to form a straight cut shingled roof line which extends generally parallel with the adjacent roof valley.
Description
CROSS-REFERENCE TO RELATED PROVISIONAL PATENT [0001] This application claims priority based on a provisional patent, specifically on the Provisional Patent Application Serial No. 60 / 551,111 filed Mar. 8, 2004.Background of the Invention [0002] 1. Technical Field [0003] The present invention relates generally to shingle cutting devices and, more particularly, to a shingle cutting device for use in roof valleys which includes a base section having an inverted guide channel formed on the underside thereof, an outwardly extending blade support arm which extends outwards from the base section at an upwards angle therefrom, and a shingle cutting blade mounted on the outer section of the outwardly extending blade support arm for engaging and cutting shingle ends to form a straight cut shingled roof line parallel with the roof valley. [0004] 2. Description of the Prior Art [0005] Asphalt shingled roofs are extremely common and are found on the vast majority of homes built in the United Stat...
