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 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.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. 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.

DETAILED DESCRIPTION OF THE INVENTION

This invention is a pneumatic shingle removing machine, intended for stripping off old shingles from a building roof which is to be re-roofed. It incorporates a linear cylinder [1], intended for actuation.
This invention is comprised of a pneumatic linear cylinder [1] connected to a deflector shield [2] which, in turn, is connected to ripper teeth [3] intended to be propelled forward under the shingles while the operator immobilizes the frame by standing on the foot hold down [4] which is equipped with ratchet teeth [5] on the bottom. The normal weight of the operator forces the ratchet teeth [5] into the roof under-layment, creating a temporary anchor point with which to force the deflector shield [2] and attached ripper teeth [3] under the shingles.
This invention advances forward when the pneumatic cylinder [1] stated previously, is retracted and the weight of the operator is removed from the foot hold [4]. The ratchet teeth [5] slip along the under-layment until the cylinder [1] is fully retracted.
This invention incorporates an air valve [6] which is attached to the T-handle [7] the operator uses to guide the machine. The valve [6] is connected to the linear cylinder [1] via air hoses, intended to direct the air pressure for forward and reverse motion. The deflector shield [2] rolls the shingles up and forward as the machine is manipulate forward down the roof.
This invention incorporates ripper teeth [3] which are angled down to stay under the shingles. Two stabilizer rods [8] are held in tubes [9], permanently fixed to the frame, with linear bearings [10], maintaining level stability.
This invention is intended to remove shingles in a timely and efficient manner compared to the current hand removal methods.
