Abstract
Abstract A ball joint or king pin tester for automotive vehicles having means to oscillate the ball joint or king pin so as to displace the wearing parts thereof with respect to one another, and having means to measure the amount of such displacement so that appropriate maintenance may be provided if necessary. The device also comprises a pressure roller for testing tire out-ofroundness.

Dependent Claim
206 words
Means for measuring the amount of play in ball joints and the like comprising a base, a pair of spaced supports erected on said base, a first rod connecting said supports, a second rod connecting said supports and spaced from said first rod, a means rotatable on said first rod and a lever fixed to said means, said lever having means at one end for supporting the load of a ball joint assembly, and an operating handle at the other end; a dial for measuring the amount of play in said assembly, a pointer mounted on said second rod for indicating the amount of said play on said dial, and means operable by the movement of said lever and actuating said pointer to indicate the amount of play on said dial, the zero of said dial being adjustable with respect to said pointer so, that a reading can be taken thereof of the movement of said pointer, the pointer comprising an arm pivoted on said second rod, said arm having a pin extending therefrom into the path of a second arm, and said operating means comprises said second arm on said rotatable means, said second arm being engagable with said pin when said lever is operated.
Claim 3
Dependent Claim
123 words
Testing and measuring apparatus for a vehicle wheel front end assembly, comprising a support, a pair of motion detecting devices mounted by the support, indicating means mounted by the support for alternatively gauging the amount of motion sensed by each of the detecting devices, and means for transmitting motion sensed by the detecting devices to the indicating means, including means for isolating the indicating means from force exerted by one of the detecting devices while the other of the detecting devices is sensing motion, each of the detecting devices including means for engaging the vehicle wheel, said other of the detecting devices further inCluding means for biasing the indicating means into engagement with the transmitting means of said one of the detecting devices.
Claim 4
Dependent Claim
123 words
Testing and measuring apparatus for a vehicle wheel front end assembly, comprising a support, a pair of motion detecting devices mounted by the support, indicating means mounted by the support for alternatively gauging the amount of motion sensed by each of the detecting devices, and means for transmitting motion sensed by the detecting devices to the indicating means, including means for isolating the indicating means from force exerted by one of the detecting devices while the other of the detecting devices is sensing motion, each of the detecting devices including means for engaging the vehicle wheel, said other of the detecting devices further inCluding means for biasing the indicating means into engagement with the transmitting means of said one of the detecting devices.
Claim 5
Dependent Claim
150 words
Means for measuring the amount of axial play in ball joints or the like, comprising a support, a pair of spaced pivot assemblies mounted by the support, a lever connected to one of the pivot assemblies having a wheel periphery engagement member and an operating handle to effect engagement of said member with a wheel periphery at the lower side thereof and operative to lift said wheel thereby to an extent determined by axial ball joint play; a pointer connected to the other of the pivot assemblies, dial means mounted by the support for adjustable positioning relative to the pointer, operating means connected to the lever and responsive to movement thereof for actuating the pointer to indicate the amount of axial play on the dial means, said operating means including an arm projecting from said one of the pivot assemblies and engagable with the pointer during operation of the lever.
Claim 6
Dependent Claim
150 words
Means for measuring the amount of axial play in ball joints or the like, comprising a support, a pair of spaced pivot assemblies mounted by the support, a lever connected to one of the pivot assemblies having a wheel periphery engagement member and an operating handle to effect engagement of said member with a wheel periphery at the lower side thereof and operative to lift said wheel thereby to an extent determined by axial ball joint play; a pointer connected to the other of the pivot assemblies, dial means mounted by the support for adjustable positioning relative to the pointer, operating means connected to the lever and responsive to movement thereof for actuating the pointer to indicate the amount of axial play on the dial means, said operating means including an arm projecting from said one of the pivot assemblies and engagable with the pointer during operation of the lever.
Claim 7
Dependent Claim
54 words
The combination of claim 3 including a second lever, a third pivot assembly pivotally mounting the second lever on the support, load engaging means mounted on the second lever for displacement thereof, yieldable means connecting the second lever to the pointer, and means for biasing the second lever out of engagement with the pointer.
Claim 8
Dependent Claim
45 words
The combination of claim 4 including stop means engagable with the first mentioned lever for selectively preventing engagement between the second lever and the pointer, whereby the biasing means urges the pointer into engagement with the arm through the second lever and the yieldable means.
Claim 9
Dependent Claim
150 words
A front wheel suspension assembly testing device for measuring axial and radial play particularly in ball joints of a suspension, comprising support means having a fulcrum element and an actuating lever pivotally fulcrummed thereon and having a wheel engaging member and a handle on opposite sides of the fulcrum element, whereby a vehicle wheel periphery can be engaged by said member by actuation of said handle and said wheel then lifted to an extent determined by axial play in said suspension in a plane substantially perpendicular to a floor on which the support means stands, and indicating means coupled to said lever to indicate extent extend of said play, said member being disposed horizontally outwardly of said support means and at a level relative to said floor so as to engage said wheel at a lowermost portion of the periphery thereof with said support means spaced horizontally from said wheel.
Claim 10
Dependent Claim
150 words
A front wheel suspension assembly testing device for measuring axial and radial play particularly in ball joints of a suspension, comprising support means having a fulcrum element and an actuating lever pivotally fulcrummed thereon and having a wheel engaging member and a handle on opposite sides of the fulcrum element, whereby a vehicle wheel periphery can be engaged by said member by actuation of said handle and said wheel then lifted to an extent determined by axial play in said suspension in a plane substantially perpendicular to a floor on which the support means stands, and indicating means coupled to said lever to indicate extent extend of said play, said member being disposed horizontally outwardly of said support means and at a level relative to said floor so as to engage said wheel at a lowermost portion of the periphery thereof with said support means spaced horizontally from said wheel.
