ALEXANDRIA, Va., March 17 -- United States Patent no. 12,575,579, issued on March 17, was assigned to Hall Fabrication Inc. (Henderson, Nev.).

"Scribe saw mount for loin puller machine" was invented by David Chappell (Las Vegas).

According to the abstract* released by the U.S. Patent & Trademark Office: "A loin puller machine is provided with a scribe saw assembly that longitudinally aligns the scribe saw blade with the actuator for raising and lowering the blade. By positioning the blade directly in front of the actuator, the actuator forces are centrally aligned with the blade so as to reduce binding and bearing wear. The alignment of the blade minimizes maintenance and increases productivity and profitability."
