Abstract
Abstract An apparatus for checking vehicle shock absorbers in installed condition which comprises vertically oscillatable plate means for receiving and supporting a vehicle wheel, said plate means being adapted to be subjected to oscillations for causing the wheel axle mass to carry out sympathetic vibrations the amplitudes of which are measured by a gauge.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
178 words
An apparatus for individually checking a shock absorber installed on a vehicle equipped with an axle and wheel and having a shock absorber associated with vehicle spring means, comprising a fixed base, a support member for supporting a single wheel of said vehicle and its axle, means to support said support member on said fixed base for vertical movement, including a spring having one end in fixed engagement with a part of said fixed base and its opposite end connected to said means to support said support member to resist vertical movement of said support member, means to vibrate said support member including a movable mass connected to said means to support said support member and mounted for movement of its center of mass relative to said support member, and means to drive said mass cyclically to set up vertical oscillations of said support member, so as to vibrate the vehicle wheel and to subject the axle mass to sympathetic vibrations, and indicating means operatively connectable to said axle mass for indicating the amplitude of said sympathetic vibrations.
Claim 2
Independent Claim
178 words
An apparatus for individually checking a shock absorber installed on a vehicle equipped with an axle and wheel and having a shock absorber associated with vehicle spring means, comprising a fixed base, a support member for supporting a single wheel of said vehicle and its axle, means to support said support member on said fixed base for vertical movement, including a spring having one end in fixed engagement with a part of said fixed base and its opposite end connected to said means to support said support member to resist vertical movement of said support member, means to vibrate said support member including a movable mass connected to said means to support said support member and mounted for movement of its center of mass relative to said support member, and means to drive said mass cyclically to set up vertical oscillations of said support member, so as to vibrate the vehicle wheel and to subject the axle mass to sympathetic vibrations, and indicating means operatively connectable to said axle mass for indicating the amplitude of said sympathetic vibrations.
Claim 3
Independent Claim
178 words
An apparatus for individually checking a shock absorber installed on a vehicle equipped with an axle and wheel and having a shock absorber associated with vehicle spring means, comprising a fixed base, a support member for supporting a single wheel of said vehicle and its axle, means to support said support member on said fixed base for vertical movement, including a spring having one end in fixed engagement with a part of said fixed base and its opposite end connected to said means to support said support member to resist vertical movement of said support member, means to vibrate said support member including a movable mass connected to said means to support said support member and mounted for movement of its center of mass relative to said support member, and means to drive said mass cyclically to set up vertical oscillations of said support member, so as to vibrate the vehicle wheel and to subject the axle mass to sympathetic vibrations, and indicating means operatively connectable to said axle mass for indicating the amplitude of said sympathetic vibrations.
Claim 4
Independent Claim
178 words
An apparatus for individually checking a shock absorber installed on a vehicle equipped with an axle and wheel and having a shock absorber associated with vehicle spring means, comprising a fixed base, a support member for supporting a single wheel of said vehicle and its axle, means to support said support member on said fixed base for vertical movement, including a spring having one end in fixed engagement with a part of said fixed base and its opposite end connected to said means to support said support member to resist vertical movement of said support member, means to vibrate said support member including a movable mass connected to said means to support said support member and mounted for movement of its center of mass relative to said support member, and means to drive said mass cyclically to set up vertical oscillations of said support member, so as to vibrate the vehicle wheel and to subject the axle mass to sympathetic vibrations, and indicating means operatively connectable to said axle mass for indicating the amplitude of said sympathetic vibrations.
Claim 5
Dependent Claim
249 words
A stand for individually checking shock absorbers of a vehicle having axle means supported on wheels at each end and equipped with shock absorbers associated with vehicle springs, which comprises two checking devices spaced from each other so as to define therebetween a distance approximately corresponding to the tread gauge of a vehicle with the smallest tread gauge the shock absorbers of which are to be checked, each of said checking devices including a separate support member operable to receive and support a vehicle wheel and its axle, said support member extending outwardly laterally sufficiently to accommodate to axles and wheels of vehicles having tread gauges greater than said smallest tread gauge, a fixed base for each support member, means to support each of said support members on a fixed base for vertical movement including a spring having one end in fixed engagement with a part of said fixed base and its opposite end connected to said support member to resist vertical movement of said support member, means to vibrate each support member including a movable mass connected to each support member and mounted for movement of its center of mass relative to said support member and means to drive said mass cyclically to set up vertical oscillations of said support member, so as to vibrate the vehicle wheel on said support member and to subject the axle mass to sympathetic vibrations, and indicating means operativelY connected to said axle mass for indicating the amplitudes of said sympathetic vibrations.
Claim 6
