Abstract
Abstract An exercising machine has a handlebar swingable back and forth about a vertical axis and a pair of cranks, each provided with a foot pedal, and swingable up and down about a horizontal axis. A reciprocable connector causes simultaneous swinging of the handlebar and the cranks. The oscillatory movements of the handlebar and the cranks permit the use of leg and/or arm power by the operator to provide much the same type of bodily movements and muscular activity as is normal in walking, jogging and running exercises.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
214 words
An exercising machine for permitting physical exertion and bodily movements comparable to the normal, human acts of walking, running or jogging for the sake of developing and maintaining physical fitness, said machine comprising: a frame having base means, presenting a bottom by which the frame is supported and stabilized in an immobile condition on an underlying surface; a handlebar having a pair of spaced portions adapted to be grasped by the hands; means intermediate the ends of the handlebar between said portions pivotally mounting the same on the frame for oscillatory movement about an essentially upright axis extending upwardly from the frame; a pair of elongated cranks, one on each side respectively of the frame and disposed downwardly and rearwardly of the handlebar above said surface; means for each crank respectively pivotally attaching the same to the frame for limited oscillatory movement about a substantially horizontal axis transversely of the frame; means operably intercoupling the cranks for simultaneous oscillation; a foot pedal pivotally secured to each crank respectively at one of the ends of the cranks; and means operably interconnecting one of the cranks and said pivotally mounting means for synchronizing the oscillatory movements of the handlebar and the cranks whereby said movements may be powered by a human operator's legs, arms or both.
Claim 2
Dependent Claim

An exercising machine for permitting physical exertion and bodily movements comparable to the normal, human acts of walking, running or jogging for the sake of developing and maintaining physical fitness, said machine comprising: a frame having base means, presenting a bottom by which the frame is supported and stabilized in an immobile condition on an underlying surface; a handlebar having a pair of spaced portions adapted to be grasped by the hands; means intermediate the ends of the handlebar between said portions pivotally mounting the same on the frame for oscillatory movement about an essentially upright axis extending upwardly from the frame; a pair of elongated cranks, one on each side respectively of the frame and disposed downwardly and rearwardly of the handlebar above said surface; means for each crank respectively pivotally attaching the same to the frame for limited oscillatory movement about a substantially horizontal axis transversely of the frame; means operably intercoupling the cranks for simultaneous oscillation; a foot pedal pivotally secured to each crank respectively at one of the ends of the cranks; and means operably interconnecting one of the cranks and said pivotally mounting means for synchronizing the oscillatory movements of the handlebar and the cranks whereby said movements may be powered by a human operator's legs, arms or both.
Claim 3
Dependent Claim

Claim 6
Dependent Claim
38 words
The invention of claim 1, each crank having a laterally extending element at the opposite end thereof provided with a bearing secured rigidly to the frame, said elements and said bearings forming a part of said attaching means.
Claim 7
Dependent Claim

Claim 11
Dependent Claim
11 words
The invention of claim 9, the upper links being rigidly interconnected.
Claim 12
Dependent Claim
32 words
The invention of claim 9, said intercoupling means including a cross-pin carried by the frame for oscillation about an axis disposed in spaced parallelism with the axes of oscillation of the cranks.

Claim 16
Dependent Claim
221 words
An exercising machine comprising: a frame; a handlebar disposed at an uppermost and forwardmost extremity of the frame, said handlebar having a pair of spaced end portions adapted to be grasped by the hands; means pivotally mounting the handlebar on the frame for limited oscillation of less than 360 degrees alternately to the right and to the left about an essentially upright axis; a pair of elongated cranks, one on each side respectively of the frame and disposed downwardly and rearwardly of the handlebar, each crank being provided with a foot pedal; means for each crank respectively pivotally attaching the same to the frame for limited oscillatory movement of less than 360 degrees about a substantially horizontal axis; means operably intercoupling the cranks for movement of one of the pedals upwardly and forwardly as the other pedal moves downwardly and rearwardly such that said one pedal moves downwardly and rearwardly as said other pedal moves upwardly and forwardly; and means for rotating the handlebar to the right as said one pedal moves upwardly and forwardly and swinging the handlebar to the left as said other pedal moves upwardly and forwardly such that, as the one pedal moves downwardly and rearwardly, the handlebar swings to the left and, as the other pedal moves upwardly and forwardly, the handlebar swings to the left.
Claim 17
Dependent Claim
221 words
An exercising machine comprising: a frame; a handlebar disposed at an uppermost and forwardmost extremity of the frame, said handlebar having a pair of spaced end portions adapted to be grasped by the hands; means pivotally mounting the handlebar on the frame for limited oscillation of less than 360 degrees alternately to the right and to the left about an essentially upright axis; a pair of elongated cranks, one on each side respectively of the frame and disposed downwardly and rearwardly of the handlebar, each crank being provided with a foot pedal; means for each crank respectively pivotally attaching the same to the frame for limited oscillatory movement of less than 360 degrees about a substantially horizontal axis; means operably intercoupling the cranks for movement of one of the pedals upwardly and forwardly as the other pedal moves downwardly and rearwardly such that said one pedal moves downwardly and rearwardly as said other pedal moves upwardly and forwardly; and means for rotating the handlebar to the right as said one pedal moves upwardly and forwardly and swinging the handlebar to the left as said other pedal moves upwardly and forwardly such that, as the one pedal moves downwardly and rearwardly, the handlebar swings to the left and, as the other pedal moves upwardly and forwardly, the handlebar swings to the left.
