Abstract
A pneumatic shingle removing machine, actuated by a linear cylinder, for the purpose of removing shingles from a roof. The machine includes a pneumatic cylinder connected to the deflector shield which moves the attached ripper teeth forward under the shingles while the operator immobilizes the frame by standing on the foot hold down with ratchet teeth on the bottom.
On the reverse stroke of the cylinder, the operator removes his foot from the hold down allowing the frame to ratchet forward for the next stroke.
An air valve is attached to the T-Handle and hoses are connected to the pneumatic cylinder for the purpose of directing air pressure for forward and reverse motion.
The deflector shield rolls the shingles up and forward as the machine is manipulated forward down the roof.
The ripper teeth are angled down to stay under the shingles, and two stabilizer rods held in the tubes, permanently affixed to the frame, with linear bearings, maintain level stability.

- The present invention relates to shingle removing machines and more particularly pertains to a new pneumatic shingle removing machine for facilitating the removal of roofing shingles from under-layment.
- 2. Description of the Prior Art
- The use of stripping machines is known in the prior art. More specifically, stripping machines heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements. Known prior art includes U.S. Pat. No. 6,467,377; U.S. Pat. No. 4,858,503; U.S. Pat. No. 5,741,047; U.S. Pat. No. 4,691,439; U.S. Pat. No. 4,709,479; U.S. Pat. No. 5,863,100; and U.S. Pat. No. Des. 327,206.
- While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new pneumatic shingle removing machine. The inventive device includes a T-handle with an air valve, coupled to a pneumatic cylinder by an air hose assembly, the aforementioned pneumatic cylinder coupled to the deflector shield with attached ripper teeth, which is selectively extendable relative to the frame for facilitating the removal shingles.
- In these respects, the pneumatic shingle removing machine according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of facilitating the removal of roofing shingles from under-layment.
- In view of the foregoing disadvantages inherent in the known types of stripping machines now present in the prior art, the present invention provides a new pneumatic shingle removing machine construction wherein the same can be utilized for facilitating the removal of roofing shingles from under-layment.
- The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new pneumatic shingle removing machine apparatus and method which has many of the advantages of the stripping machines mentioned heretofore and many novel features that result in a new pneumatic shingle removing machine which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art stripping machines, either alone or in any combination thereof.
- To attain this, the present invention generally comprises a T-handle with an air valve, coupled to a pneumatic cylinder by an air hose assembly, the aforementioned pneumatic cylinder coupled to the deflector shield with attached ripper teeth, which is selectively extendable relative to the frame for facilitating the removal shingles.
- There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
- As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
- Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. The abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
- It is therefore an object of the present invention to provide a new pneumatic shingle removing machine apparatus and method which has many of the advantages of the stripping machines mentioned heretofore and many novel features that result in a new pneumatic shingle removing machine which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art stripping machines, either alone or in any combination thereof.
- It is another object of the present invention to provide a new pneumatic shingle removing machine which may be easily and efficiently manufactured and marketed.
- It is a further object of the present invention to provide a new pneumatic shingle removing machine which is of a durable and reliable construction.
- An even further object of the present invention is to provide a new pneumatic shingle removing machine which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such pneumatic shingle removing machine economically available to the buying public.
- Still yet another object of the present invention is to provide a new pneumatic shingle removing machine which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith.
- Still another object of the present invention is to provide a new pneumatic shingle removing machine for facilitating the removal of roofing shingles from under-layment.
- Yet another object of the present invention is to provide a new pneumatic shingle removing machine which includes a T-handle with an air valve, coupled to a pneumatic cylinder by an air hose assembly, the aforementioned pneumatic cylinder coupled to the deflector shield with attached ripper teeth, which is selectively extendable relative to the frame for facilitating the removal shingles.
- Still yet another object of the present invention is to provide a new pneumatic shingle removing machine that has a compact form factor increasing the maneuverability of the machine.
- Even still another object of the present invention is to provide a new pneumatic shingle removing machine that reduces the potential for injury by reducing the repetitive operations necessary to remove shingles.
- These together with other objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be made to the accompanying drawings and descriptive matter in which there are illustrated preferred embodiments of the invention.
