Nonthreaded Load Sensing Probe

US Patent:
5402689, Apr 4, 1995
Filed:
Nov 4, 1993
Appl. No.:
8/147828
Inventors:
Richard J. Grogan - Perrysburg OH
Assignee:
Helm Instrument Co., Inc. - Maumee OH
International Classification:
G01L 122
US Classification:
73862635
Abstract:
An apparatus for sensing forces applied to a structure includes a generally cylindrical body having a pair of end portions and a smaller diameter intermediate portion with a central aperture extending longitudinally through the body. The end portions are slotted to form radially outwardly translatable legs for engaging a wall of a cavity formed in the structure. Strain gauges are attached to the intermediate portion for sensing forces applied to the structure when the body is positioned in the cavity and the legs are engaging the wall of the cavity. The wall of the central aperture has a pair of threaded sections for threadably receiving bushing and bearing assemblies inserted from opposite ends of the central aperture. Each of the assemblies has a tapered surface for radially outwardly translating the legs. One of the assemblies has an allen wrench receiving cavity accessible through one of the open ends of the central aperture and the other one of assemblies has an allen wrench receiving cavity accessible from outside the body.
