Drive Motor Mount For Clamshell Lathe
view source
US Patent:

6427567, Aug 6, 2002
Filed:

Jun 16, 2000
Appl. No.:

09/596155
Inventors:

Donato L. Ricci - Hager City WI 54017
Brent Place - Red Wing MN
Assignee:

Donato L. Ricci - Hager City WI
International Classification:

B23B 508
US Classification:

82113, 82128, 82119
Abstract:

An improved motor mount for attaching a drive motor to a clamshell lathe includes a gear box whose angular disposition can be adjusted relative to a drive gear housing affixed to the periphery of the clamshell lathe. This facilitates the positioning of the clamshell lathe on a workpiece with reduced chance of interference of the drive motor with neighboring obstructions.

US Patent:

6615696, Sep 9, 2003
Filed:

Dec 10, 2001
Appl. No.:

10/013076
Inventors:

Donato L. Ricci - Hager City WI 54014
Brent Place - Hager City WI
Assignee:

Donato L. Ricci - Hager City WI
International Classification:

B23B 516
US Classification:

82113, 82128, 82131
Abstract:

A machine tool for re-surfacing gasket seats surrounding elliptical openings in oval manways includes a housing of an oval configuration that is adapted to be mounted in the opening of the manway to be machined. A motor and a tool slide assembly are secured to the motor mount in such a fashion that the tool slide assembly is confined to travel in an oval orbit along a second major surface of the housing. A cam actuated feed screw is appropriately disposed to engage a tripper bar disposed in the path of travel to effect radial displacement of a tool holder and tool bit. A cam locking and unlocking control lever cooperates with the cam and is disposed such that an operator located outside of the vessel on which the manway is disposed can readily control the machining operation.

Appl. No.:

10/279327
Inventors:

Donato L. Ricci - Hager City WI 54014
Brent Place - Hager City WI
Assignee:

Donato L. Ricci - Hager City WI
International Classification:

B23B 508
US Classification:

82113, 82128
Abstract:

Disclosed is a portable machining lathe for machining a pipe or similar workpiece. The lathe includes two semicircular members having a stationary section and a rotatable section. The two semicircular members are cooperatively connected by a hinge system on one end, and steel splice plates on the other. The hinge has a top bracket and bottom bracket on the stationary section of each member, and a male hinge and female hinge on the rotatable section of each member. The male and female hinges are cooperatively connected so that when the hinge is closed the two semicircular members form a complete annulus.

US Patent:

6799494, Oct 5, 2004
Filed:

Oct 6, 2003
Appl. No.:

10/679904
Inventors:

Donato L. Ricci - Hager City WI 54017
Brent Place - Hager City WI
Assignee:

Donato L. Ricci - Hager City WI
International Classification:

B23B 514
US Classification:

82113, 82 46
Abstract:

The intermediate support brace is used to prevent bending or deflecting of a cylindrical work piece being machined by a journal turning lathe. A U-shaped frame is mounted to the journal turning lathe, and secured to the journal turning lathe by a first and second clamping means which secure the intermediate support brace to the guide rails of the journal turning lathe. A generally circular opening in the frame surrounds the cylindrical work piece, and the work piece is centered by a series of jacks. The clamshell lathe assembly is translated from a first end bracket to the intermediate support bracket. The clamshell lathe is then stopped; the intermediate support bracket is released and mounted downstream from the clamshell lathe assembly. The clamshell lathe assembly is then restarted and translated to a second end bracket.
