View page
US Patent:
46829210, Jul 28, 1987
Filed:
Nov 8, 1985
Appl. No.:
6/796650
Inventors:
Lester J. Blaho - Ambridge PA
Assignee:
Pittsburgh Tube Company - Monaca PA
International Classification:
B23D 108
US Classification:
409299
Abstract:
A scarfing tool for scarfing the inside of a tube-like member in which an elongated body is adapted for attachment to the end of an impeder rod. The body includes a cutting tool and a pair of spaced apart rollers aligned with the cutting tool. A thrust roller is pivotably mounted to the side of the body opposite from the cutting tool and rollers to force the cutting tool against the inner area of the tube member to be scarfed. A pair of first and second hydraulic means having associated pistons which are connected to a common source of hydraulic fluid. The first hydraulic piston is operably connected to said thrust roller for actuating said roller into extended contact with the inner tube member and the second piston is operably connected to a bias means to work against said means as the thrust roller is extended by the first hydraulic piston.

US Patent:
48939722, Jan 16, 1990
Filed:
Nov 18, 1988
Appl. No.:
7/273275
Inventors:
Lester J. Blaho - Monaca PA
Assignee:
Pittsburgh Tube Company - Monaca PA
International Classification:
B23D 124
US Classification:
409299
Abstract:
The present invention pertains to a cutting tool for removing upset from inside a tube and which does not force splatter into the inside surface of the tube. The cutting tool comprises a holder and means for enabling the tube to move along the holder. The enabling means is connected to the holder. The cutting tool is also comprised of means for removing the upset inside the tube. The removing means is connected to the holder such that as the tube moves along the holder, the removing means removes the upset from the inside of the tube. There is also means for preventing splatter from being forced into the inside of the tube by the enabling means as the tube moves along the holder. Preferably, the enabling means includes a roller connected to the holder such that the holder can roll along the tube on the roller, and the preventing means includes means for introducing fluid upstream from the roller such that the fluid prevents splatter from being rolled into the inside of the tube by the roller as the tube moves along the holder. The fluid creates a fluid barrier which forces the splatter around the roller so the splatter is not rolled into the inside surface of the tube.
