Abstract
Abstract An arm wrestling machine including an operating arm pivotally mounted on a base and two assemblies for exerting forces on the operating arm urging the operating arm toward a vertical position. One assembly includes a spring connected between the operating arm and a spring support mounted on a screw for linear movement toward and away from the operating arm so that such assembly provides an adjustable, continuous force on the operating arm. The other assembly includes a pneumatic cylinder connected between the operating arm and the base and intermittently receiving bursts of compressed air from a valve that is mounted on the operating arm so that the case of the valve moves with the operating arm and having a weight attached to the valve member of the valve so that movement of the operating arm intermittently opens the valve.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
87 words
An arm wrestling machine, comprising: a base; an operating arm pivotally supported on the base for pivoting movement thereon away from a rest position of the operating arm; first biasing means, connected between the base and the operating arm, for continuously urging the operating arm, when the latter is pivoted, toward said rest position; and second biasing means, connected below the base and to the pivoted operating arm, for intermittently urging the operating arm toward said rest position after a predetermined movement of said first biasing means.
Claim 2
Dependent Claim
87 words
An arm wrestling machine, comprising: a base; an operating arm pivotally supported on the base for pivoting movement thereon away from a rest position of the operating arm; first biasing means, connected between the base and the operating arm, for continuously urging the operating arm, when the latter is pivoted, toward said rest position; and second biasing means, connected below the base and to the pivoted operating arm, for intermittently urging the operating arm toward said rest position after a predetermined movement of said first biasing means.
Claim 3
Dependent Claim
33 words
The arm wrestling machine of claim 1 wherein the first biasing means is characterized as comprising means for adjusting the force with which the operating arm is continuously urged toward said rest position.
Claim 4
Dependent Claim
114 words
The arm wrestling machine of claim 2 wherein the first biasing means is further characterized as comprising a coil spring having one end thereof attached to the operating arm for exerting said force with which the operating arm is continuously urged toward said rest position; and wherein the means for adjusting the force with which the operating arm is continuously urged toward said rest position comprises: a spring support attached to the other end of said coil spring; and means for mounting the spring support on the base for linear movement of the spring support toward and away from the operating arm, thereby adjusting the force the coil spring exerts on the operating arm.
Claim 5
Dependent Claim
31 words
The arm wrestling machine of claim 3 further comprising: a scale mounted on the base; and a pointer attached to the spring support and having a portion thereof overlaying said scale.
Claim 6
Dependent Claim
31 words
The arm wrestling machine of claim 2 further comprising means for indicating the force with which the operating arm is continuously urged toward the rest position by the first biasing means.
Claim 7
Dependent Claim
124 words
The arm wrestling machine of claim 5 wherein the second biasing means comprises: a pneumatic cylinder connected between the base and the operating arm for urging the operating arm toward the rest position thereon in response to compressed air introduced into said pneumatic cylinder; a pneumatic valve having an inlet port to receive compressed air and an outlet port connected to said pneumatic cylinder, wherein the pneumatic valve is characterized as being of the type having a control member positionable to internally connect the inlet port of the pneumatic valve to the outlet port thereof and alternatively positionable to exhaust said outlet port; and means for intermittently positioning the control member of the pneumatic valve for internally connecting the inlet and outlet ports thereof.
Claim 8
Dependent Claim
82 words
The arm wrestling machine of claim 6 wherein the pneumatic valve is mounted on said operating arm; wherein the operating member of the valve is characterized as being rotationally positionable about an axis lateral to the operating arm for alternatively connecting the inlet and outlet ports of the pneumatic valve and exhausting the outlet port thereof; and wherein the means for intermittently positioning the control member of the pneumatic valve comprises a weight suspended from the control member of the pneumatic valve.
Claim 9
Dependent Claim
124 words
The arm wrestling machine of claim 2 wherein the second biasing means comprises: a pneumatic cylinder connected between the base and the operating arm for urging the operating arm toward the rest position thereon in response to compressed air introduced into said pneumatic cylinder; a pneumatic valve having an inlet port to receive compressed air and an outlet port connected to said pneumatic cylinder, wherein the pneumatic valve is characterized as being of the type having a control member positionable to internally connect the inlet port of the pneumatic valve to the outlet port thereof and alternatively positionable to exhaust said outlet port; and means for intermittently positioning the control member of the pneumatic valve for internally connecting the inlet and outlet ports thereof.
Claim 10
Dependent Claim
82 words
The arm wrestling machine of claim 8 wherein the pneumatic valve is mounted on said operating arm; wherein the operating member of the valve is characterized as being rotationally positionable about an axis lateral to the operating arm for alternatively connecting the inlet and outlet ports of the pneumatic valve and exhausting the outlet port thereof; and wherein the means for intermittently positioning the control member of the pneumatic valve comprises a weight suspended from the control member of the pneumatic valve.
Claim 11
Dependent Claim
124 words
The arm wrestling machine of claim 1 wherein the second biasing means comprises: a pneumatic cylinder connected between the base and the operating arm for urging the operating arm toward the rest position thereon in response to compressed air introduced into said pneumatic cylinder; a pneumatic valve having an inlet port to receive compressed air and an outlet port connected to said pneumatic cylinder, wherein the pneumatic valve is characterized as being of the type having a control member positionable to internally connect the inlet port of the pneumatic valve to the outlet port thereof and alternatively positionable to exhaust said outlet port; and means for intermittently positioning the control member of the pneumatic valve for internally connecting the inlet and outlet ports thereof.
Claim 12
Dependent Claim
82 words
The arm wrestling machine of claim 10 wherein the pneumatic valve is mounted on said operating arm; wherein the operating member of the valve is characterized as being rotationally positionable about an axis lateral to the operating arm for alternatively connecting the inlet and outlet ports of the pneumatic valve and exhausting the outlet port thereof; and wherein the means for intermittently positioning the control member of the pneumatic valve comprises a weight suspended from the control member of the pneumatic valve.
