US Patent:
6412325, Jul 2, 2002
Filed:
Mar 23, 1999
Appl. No.:
09/275132
Inventors:
Edward M. Croswell - Metamora MI
Assignee:
3 Dimensional Services - Rochester Hills MI
International Classification:
B21D 4328
US Classification:
72324, 723421, 723792
Abstract:
A method for prototyping parts from a sheet metal blank in which the sheet metal has at least two spaced edges. The method includes the step of forming a plurality of longitudinally aligned slots through the sheet metal blank to form a bend line extending between two spaced edges on the sheet metal blank. The slots are preferably formed by laser cutting. The sheet metal blank is then bent along the bend line to form the prototype.
Trailer Hitch Mounted Lifting Attachment
US Patent:
6164895, Dec 26, 2000
Filed:
Apr 7, 1999
Appl. No.:
9/287708
Inventors:
Edward M. Croswell - Metamora MI
International Classification:
B60P 900
US Classification:
414462
Abstract:
A lifting attachment is disclosed for use in conjunction with a trailer hitch mounted to a vehicle. The lifting attachment includes a support assembly which is detachably connected to the trailer hitch and this support assembly includes a vertically extending support beam. The attachment includes a platform having a generally planar top and an elongated arm having one end pivotally connected to the platform and a second end pivotally connected to the support beam. A hydraulic piston and cylinder assembly is pivotally connected between the support beam and an intermediate point on the arm so that extension and retraction of the piston within the cylinder selectively raises and lowers the platform.
