US Patent:

8061249, Nov 22, 2011

Filed:

Oct 28, 2009

Appl. No.:

12/589761

Inventors:

Lyle D. Kaehr - Decatur IN, US
James A. Kaehr - Lagro IN, US

International Classification:

B26D 3/16
B26D 3/00

US Classification:

83456, 831687, 83648, 83657, 30 96, 30101, 30102

Abstract:

A pipe cutting apparatus having a frame and first and second pipe support arms. The pipe support arms are pivotally attached to the frame. First and second pipe support members on the first and second arms together with a third pipe support member securely grip the pipe at substantially equally circumferentially spaced locations. A camming member is used to place the first and second pipe support arms in predefined locations for holding differently sized pipes. An linkage assembly causes the third pipe support member to biasingly engage the pipe. A two-part tool shield is provided together with a depth adjusting assembly for facilitating the cutting and beveling of the pipe. A power transmission assembly transfers power from a motor on the frame to a tool located on a pivoting arm. The frame may be manufactured using an adhesive filler material for enhancing the rigidity, strength and accuracy of the components.
