Patent number: 8376331Abstract: An elastomeric isolator has an elastomeric body which incorporates an inner structural member and an outer structural member. The elastomeric body includes a shear hub extending between radial flanges defined by the inner and outer structural members that undergoes shearing stresses during deflection of the elastomeric isolator. The inner and outer structural members are designed to provide a travel stop for the elastomeric isolator in order to avoid compression of the shear hub during high loads. The elastomeric bushing can also include an optional integral elastomeric heat shield which protects the shear hub.Type: GrantFiled: February 11, 2009Date of Patent: February 19, 2013Assignee: The Pullman CompanyInventor: Troy P. Rodecker

Patent number: 8366069Abstract: An isolator assembly includes an elastomeric assembly which is disposed within a socket defined by a supporting structure. The socket defines a transition portion, a retention rib and a stopping rib. The elastomeric assembly is positioned in the socket by sliding the elastomeric assembly through the transition portion so that the elastomeric assembly is compressed as it moves into the retention rib. The stopping rib engages an end surface of the elastomeric assembly once it has been properly positioned in the socket.Type: GrantFiled: January 19, 2011Date of Patent: February 5, 2013Assignee: The Pullman CompanyInventor: Troy P.

Publication number: 20120312954Abstract: A system for mounting a catalytic converter of an exhaust system to an internal combustion engine includes a bracket adapted to fix the catalytic converter to the engine. A strap is adapted to circumferentially extend about a portion of the catalytic converter and clamp the catalytic converter to the bracket. The bracket includes a seat, a mounting pad and a compliant portion interconnecting the seat and the mounting pad. The seat supports a portion of the catalytic converter opposite the strap. The compliant portion includes a slot extending adjacent to the seat to reduce the stiffness of the bracket and allow the bracket to deflect during thermal expansion of the catalytic converter.Type: ApplicationFiled: June 7, 2011Publication date: December 13, 2012Inventors: Troy P.

Publication number: 20120056070Abstract: A coulomb damper is attached to a component of an exhaust system. The inner surface of the coulomb damper is in intimate contact with the outer surface of the component of the exhaust system. The intimate contact is defined by a pair of weld lines extending along an axial length of the coulomb damper in one embodiment. In another embodiment, the intimate contact is defined by at least a three point contact between the coulomb damper and the component of the exhaust system.Type: ApplicationFiled: March 17, 2011Publication date: March 8, 2012Applicant: THE PULLMAN COMPANYInventor: Troy P.

Patent number: 8066266Abstract: An elastomeric isolator has an elastomeric body which incorporates an inner structural member and an outer structural member. The elastomeric body includes a shear hub extending between radial flanges or end plates of the inner and outer structural members that undergoes shearing stresses during deflection of the elastomeric isolator. The elastomeric body is bonded to the radial flanges or end plates. The inner structural member includes a radial flange which is axially offset from an axial flange of the outer structural member. The outer structural member includes a radial flange which is axially offset from an axial flange of the inner structural member. With this configuration, excessive stresses on the elastomeric body are avoided during high load movements of the elastomeric isolator.Type: GrantFiled: March 6, 2008Date of Patent: November 29, 2011Assignee: The Pullman CompanyInventor: Troy P.

Patent number: 7644911Abstract: An elastomeric isolator has an elastomeric body which defines a void extending into the elastomeric body from one side and a void extending into the elastomeric body from the opposite side. One member for attaching the elastomeric body to a component is located inside of the two voids and another member for attaching the elastomeric body to a component is located outside of the two voids. The two voids overlap a specified distance to determine the stresses and stiffness for the isolator.Type: GrantFiled: September 22, 2005Date of Patent: January 12, 2010Assignee: The Pullman CompanyInventor: Troy P.

Publication number: 20090315235Abstract: An elastomeric isolator has an elastomeric body which incorporates an inner structural member that extends through an outer structural member. The elastomeric body includes an axial shear leg extending between the inner and outer structural members that undergo shearing stresses during deflection of the elastomeric isolator. The inner structural member includes radial flanges which are axially offset from radial flanges of the outer structural member. The axial shear leg extends between the pair of radial flanges and is bonded to them at a position outside of the outer structural member. With this configuration compression of the shear hub during high loads is avoided.Type: ApplicationFiled: June 20, 2008Publication date: December 24, 2009Applicant: THE PULLMAN COMPANYInventor: Troy P.
