Abstract
Abstract An exhaust system for an automobile, or motor vehicle generally, is supported by a series of hangers on the frame or chassis of the automobile, the hangers having an exhaust conduit mounting means in the form of resilient jaws that spread apart upon insertion of the conduit and then snap in place through their own inherent resiliency to hold the conduit in the desired suspended position.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
248 words
In an exhaust system for motor vehicles having a frame and an internal combustion engine discharging exhaust gases into the system, said system including a silencing member and at least one exhaust gas conducting conduit connected to the silencing member, mounting means each comprising a single vertically extending hanger strap for supporting the system on the engine and frame at a plurality of points spaced apart lengthwise of the system, said mounting means each including a vertically extending post element and at least one conduit snap-in clamp member attached to the post element and simultaneously engaging top and bottom parts of the conduit and having a pair of laterally resilient jaws shaped to fit around at least a major portion of the periphery of said conduit and resiliently hold the conduit in the clamp member between the jaws, said jaws having ends spaced apart by less than the width of the conduit to define an expandable resilient mouth for snap-in insertion and removal of the conduit, said clamp member being formed of a single piece spring metal strip so that the jaws are inherently resilient, said strip beng shaped to have two pais of substantially straight sides and a holding side between each pair of sides, said holding side being substantially horizontal and fitting on said post element and said pairs of sides extending from said holding section and being substantially V-shaped to form said jaws and a connector securing said post to opposite sides of said strap.
Claim 2
Dependent Claim

In an exhaust system for motor vehicles having a frame and an internal combustion engine discharging exhaust gases into the system, said system including a silencing member and at least one exhaust gas conducting conduit connected to the silencing member, mounting means each comprising a single vertically extending hanger strap for supporting the system on the engine and frame at a plurality of points spaced apart lengthwise of the system, said mounting means each including a vertically extending post element and at least one conduit snap-in clamp member attached to the post element and simultaneously engaging top and bottom parts of the conduit and having a pair of laterally resilient jaws shaped to fit around at least a major portion of the periphery of said conduit and resiliently hold the conduit in the clamp member between the jaws, said jaws having ends spaced apart by less than the width of the conduit to define an expandable resilient mouth for snap-in insertion and removal of the conduit, said clamp member being formed of a single piece spring metal strip so that the jaws are inherently resilient, said strip beng shaped to have two pais of substantially straight sides and a holding side between each pair of sides, said holding side being substantially horizontal and fitting on said post element and said pairs of sides extending from said holding section and being substantially V-shaped to form said jaws and a connector securing said post to opposite sides of said strap.
Claim 3
Dependent Claim
51 words
The invention as set forth in claim 1 wherein said connector comprises a resilient U-shaped connector forming a part of said mounting means, said U-shaped connector having top ends and said post being secured to the base of the U, said top ends bein secured to opposie sides of said strap.
Claim 4
Dependent Claim
18 words
The invention as set forth in claim 2 wherein said connector is formed of an insulating non-metallic material.
Claim 5
Dependent Claim
53 words
The invention as set forth in claim 3 wherein said connector is formed of rubber tire carcass and has a bulge between the top ends and the base of the U to provide for a deformation of the U-shape and flattening of the top ends to less than the bight of the U.
Claim 6
Dependent Claim
25 words
The invention as set forth in claim 1 wherein said post provides a swivel connection for the clamp member with respect to the hanger strap.
Claim 7
Dependent Claim
214 words
In an exhaust system for motor vehicles having a frame and an internal combustion engine discharging exhaust gases into the system, said system including an exhaust gas conducting connected to the engine, mounting means including a single hanger strap supporting the system on the frame, said mounting means including a snap-in conduit clamp member supported on the hanger strap and formed of a single piece of spring metal strip and simultaneously engaging both top and bottom parts of the conduit, said clamp member being formed to have a pair of converging substantially straight laterally resilient jaws to fit around and engage the bottom periphery of said conduit and resiliently hold the conduit between the jaws, said metal strip being formed to have a pair of converging substantially straight sides extending upwardly and inwardly from the tops of said jaws and engaging the upper periphery of the conduit, said jaws having ends spaced apart by less than the width of the conduit to define an expandable resilient mouth for insertion and removal of the conduit, said clamp member having a substantially straight horizontal holding section located opposite said mouth and extending between the top ends of said straight sides, and swivel means secured to the holding section for supporting the clamp member on the hanger.
Claim 8
Dependent Claim
214 words
In an exhaust system for motor vehicles having a frame and an internal combustion engine discharging exhaust gases into the system, said system including an exhaust gas conducting connected to the engine, mounting means including a single hanger strap supporting the system on the frame, said mounting means including a snap-in conduit clamp member supported on the hanger strap and formed of a single piece of spring metal strip and simultaneously engaging both top and bottom parts of the conduit, said clamp member being formed to have a pair of converging substantially straight laterally resilient jaws to fit around and engage the bottom periphery of said conduit and resiliently hold the conduit between the jaws, said metal strip being formed to have a pair of converging substantially straight sides extending upwardly and inwardly from the tops of said jaws and engaging the upper periphery of the conduit, said jaws having ends spaced apart by less than the width of the conduit to define an expandable resilient mouth for insertion and removal of the conduit, said clamp member having a substantially straight horizontal holding section located opposite said mouth and extending between the top ends of said straight sides, and swivel means secured to the holding section for supporting the clamp member on the hanger.
Claim 9
Dependent Claim
32 words
In a system as set forth in claim 6, said swivel means including a resilient insulating connector and a vertical post providing a swivel connection securing the holding section to the connector.
