Abstract
Abstract An equalizer bar support pad structure for use in conjunction with frame supporting equalizer bars of the type used on tracked vehicles. The equalizer bar support pad structure includes a pair of tubular members secured to the upper central portion of the equalizer bar and projecting horizontally from opposite sides of the bar into the space defined between the legs of a pair of Ushaped spring metal members disposed on opposite sides of the bar, and each forming a portion of a support pad secured to the main frame support saddle. The support saddle is an arcuate member having a top plate which bears against the upper flange of the equalizer bar, but is not attached thereto. Each of the support pads, in addition to the U-shaped spring steel member, includes a body of an elastomeric material, such as rubber, which has a plurality of spring steel reinforcing elements embedded therein, and which is bonded to one or more mounting plates used for mounting the support pad to mounting brackets formed on side plates of the main frame support saddle.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
152 words
An equalizer bar support pad structure for supporting an equalizer bar on a support saddle comprising: a U-shaped spring metal member for receiving between the legs thereof, a pin carried by said equalizer bar; a body of elastomeric material having a U-shaped recess therein complementary in configuration to said U-shaped spring metal member and receiving said U-shaped spring metal member, said body of elastomeric material being bonded to said U-shaped member on one side thereof, and having a first side in which said U-shaped recess is formed, and a second side on the opposite side of said body from said first side; and angular retainer plate means secured to said body of elastomeric material and having apertured portions extending from said body in substantial alignment with the plane of said second side of said body, and in a plane extending substantially normal to the planes of the legs of said U-shaped member.
Claim 2
Dependent Claim
152 words
An equalizer bar support pad structure for supporting an equalizer bar on a support saddle comprising: a U-shaped spring metal member for receiving between the legs thereof, a pin carried by said equalizer bar; a body of elastomeric material having a U-shaped recess therein complementary in configuration to said U-shaped spring metal member and receiving said U-shaped spring metal member, said body of elastomeric material being bonded to said U-shaped member on one side thereof, and having a first side in which said U-shaped recess is formed, and a second side on the opposite side of said body from said first side; and angular retainer plate means secured to said body of elastomeric material and having apertured portions extending from said body in substantial alignment with the plane of said second side of said body, and in a plane extending substantially normal to the planes of the legs of said U-shaped member.
Claim 3
Dependent Claim
76 words
An equalizer bar support pad structure as defined in claim 1 wherein said retainer plate means comprises a pair of horizontally spaced, L- shaPed plates disposed on opposite sides of said U-shaped member and each including one of said apertured portions, and further including a second portion secured to, and extending normal to, said apertured portion and parallel to the legs of said U-shaped member, said second portion being bonded to said body of elastomeric material.
Claim 4
Dependent Claim
50 words
An equalizer bar support pad structure as defined in claim 1 wherein said retainer plate means comprises a plate extending along the lower side of said body of elastomeric material and having a portion thereof between said apertured portions bonded to the lower side of said body of elastomeric material.
Claim 5
Dependent Claim
38 words
An equalizer bar support pad structure as defined in claim 1 and further characterized to include spring metal reinforcing elements embedded in said body of elastomeric material and extending substantially parallel to the legs of said U-shaped member.
Claim 6
Dependent Claim
