Abstract
Abstract A bent wire force gage for determining loads or forces exerted by an object which is supported by the gage. The gage yields when it is subjected to load within its design range and then by using a calibration member for determining the final length between the supporting ends of the gage, the load which was lifted can be determined.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
187 words
A gage combination for determining the amount of force applied to the gage, comprising a first leg member and a second leg member which are spaced apart, third and fourth leg members connecting said first and second leg members and positioned between said first and second leg members, said third and fourth leg members being joined together adjacent first ends thereof, and opposite ends of said third and fourth leg members being joined to the first and second leg members, respectively, means to apply force to said first and second leg members at locations spaced from the junctions of said first and second leg members to said third and fourth leg members, respectively, to tend to cause separation of said first and second leg members, said force being in a range which causes permanent deformation of at least portions of said leg members whereby the deformation of said portions of said leg members indicates the amount of force applied to said gage, and means providing indicia calibrated to directly indicate the force applied to said gage in relation to the amount of separation of said leg members.
Claim 2
Dependent Claim
187 words
A gage combination for determining the amount of force applied to the gage, comprising a first leg member and a second leg member which are spaced apart, third and fourth leg members connecting said first and second leg members and positioned between said first and second leg members, said third and fourth leg members being joined together adjacent first ends thereof, and opposite ends of said third and fourth leg members being joined to the first and second leg members, respectively, means to apply force to said first and second leg members at locations spaced from the junctions of said first and second leg members to said third and fourth leg members, respectively, to tend to cause separation of said first and second leg members, said force being in a range which causes permanent deformation of at least portions of said leg members whereby the deformation of said portions of said leg members indicates the amount of force applied to said gage, and means providing indicia calibrated to directly indicate the force applied to said gage in relation to the amount of separation of said leg members.
Claim 3
Dependent Claim
14 words
The combination specified in claim 1 wherein said leg members are made of wire.
Claim 4
Dependent Claim
67 words
The combination specified in claim 1 wherein said leg members have a first normal position and said first and second leg members are longer than said third and fourth leg members to provide permanent deformation of said first and second leg members from their normal position prior to deformation of said third and fourth leg members from their normal position when force is applied to said gage.
Claim 5
Dependent Claim
145 words
A portable load gage for determining the amount of load supported by said gage across a useable load range comprising a single piece of wire bent upon itself to form at least one bend portion and at least two legs lying in a common plane extending from said bend portion and overlying each other in the direction of load application, said wire being flattened in direction of the common plane to increase the bending section of the wire in the bend portion, means on outer portions of said legs spaced from said bend portions for applying a load to be measured by said gage, said outer portions of said legs separating and the wire yielding and permanently deforming from loads applied thereto in the useable range of said gage to give an indication of the load applied by the amount of separation of said legs.
Claim 6
Dependent Claim
145 words
A portable load gage for determining the amount of load supported by said gage across a useable load range comprising a single piece of wire bent upon itself to form at least one bend portion and at least two legs lying in a common plane extending from said bend portion and overlying each other in the direction of load application, said wire being flattened in direction of the common plane to increase the bending section of the wire in the bend portion, means on outer portions of said legs spaced from said bend portions for applying a load to be measured by said gage, said outer portions of said legs separating and the wire yielding and permanently deforming from loads applied thereto in the useable range of said gage to give an indication of the load applied by the amount of separation of said legs.
Claim 7
Dependent Claim
160 words
A portable load gage for determining the amount of load supported by said gage across a useable load range comprising a single piece of wire bent upon itself to form a generally W shaped gage comprising first, second, third and fourth legs joined together by bend portions of said wire, said first and second legs being spaced apart and joined by said third and fourth legs, respectively, said first and second legs extending substantially parallel to each other, and overlying each other in the direction of load application, means on outer portions of said first and second legs spaced from said bend portions for applying a load to be measured by said gage, said outer portions of said first aNd second legs separating and the wire yielding and permanently deforming from loads applied thereto in the useable range of said gage to give an indication of the load applied by the amount of separation of said first and second legs.
Claim 8
Dependent Claim
160 words
A portable load gage for determining the amount of load supported by said gage across a useable load range comprising a single piece of wire bent upon itself to form a generally W shaped gage comprising first, second, third and fourth legs joined together by bend portions of said wire, said first and second legs being spaced apart and joined by said third and fourth legs, respectively, said first and second legs extending substantially parallel to each other, and overlying each other in the direction of load application, means on outer portions of said first and second legs spaced from said bend portions for applying a load to be measured by said gage, said outer portions of said first aNd second legs separating and the wire yielding and permanently deforming from loads applied thereto in the useable range of said gage to give an indication of the load applied by the amount of separation of said first and second legs.
Claim 9
Dependent Claim
30 words
The combination as specified in claim 5 wherein said third and fourth legs are shorter than said first and second legs, and said legs all lie in a common plane.
