Pipe beveling tool

Abstract

A pipe beveling tool has an arcuate pipe adapter mechanically attached to a wedge member, which is itself mechanically attached to a connecting bracket which is itself mechanically fastened to a disc cover member in such a way that both the disc cover member, and the connecting bracket clamp onto a grinding tool section proximal a grinding disc by way of tightening thereonto. The pipe adapter has a pair of flaps hingedly attached to a fixed adapter member so as to adapt to various pipe diameters.

Claims

1. A pipe beveling apparatus comprising a grinding tool having a grinding disc in combination with a pipe beveler tool, the improvement comprising: said pipe beveler tool having a pair of flaps hingedly attached to a fixed adapter member so as to follow a portion of a contour of a pipe regardless of its diameter; a connecting bracket being mechanically fastened to a disc cover member in such a way that both said disc cover member and said connecting bracket clamp onto said grinding tool proximal said grinding disc; said removable wedge member having a given angle and being mechanically attached between said fixed adapter member and said connecting bracket to position and secure said grinding tool at an angle relative to a pipe to facilitate carving of a corresponding bevel angle onto a circumference of said pipe at said given angle; and said connecting bracket having a pair of handles extending therefrom so as to hold said pipe beveling tool in place when said pipe is being rotated.

2. The pipe beveling apparatus as in claim 1 wherein a pair of nipples make contact with an edge section of said pipe so as to hold said pipe beveling tool in place relative to the pipe's circumferential edge when a pipe is being rotated.

3. The pipe beveling apparatus as in claim 1 wherein a removable cover extension extends the coverage of said disc beyond said cover member.

DETAILED DESCRIPTION

(7) A pipe beveling tool (10) is comprised of an arcuate pipe adapter (12) mechanically attached to a wedge member (14), which is itself mechanically attached to a connecting bracket (16) which is itself mechanically fastened to a disc cover member (18) in such a way that both the disc cover member (18), and the connecting bracket (16) clamp onto a grinding tool (20) section proximal a grinding disc (22) by way of tightening thereonto. The disc cover member (18) is a component that is standard to grinding tools (20) and its mode of attachment need not be further discussed herein. The connecting bracket (16) using the same mode of attachment therefore does not need to be further discussed either. The connecting bracket (16) has a pair of handles (24) extending therefrom.

(8) A removable cover extension (26) extends the coverage of the disc beyond the cover member (18) but is easily removable to facilitate the replacement of the grinding disc (22) when necessary.

(9) Since pipes (32) have different diameters, the pipe adapter (12) has a pair of flaps (28) hingedly attached to a fixed adapter member (30) so as to follow the contour of whatever pipe (32) diameter is on.

(10) While rotating the pipe (32), the adapter (12) is kept in place by way of the handle members (24) as well as a pair of nipples (34) which make contact with the circumferential edge of the pipe (32). In this manner, the grinder (20) is kept at a precise position relative to the circumference of the pipe (32) and thus carve a bevel that is consistent in shape. The wedge member (14) is interchangeable and comes in a variety of shapes which represent different angles so that the bevel can be cut in any given pre-selected angle.

(11) With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

(12) Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
