Abstract
Abstract A tractor implement employs a torque rod having an angularly offset projection, a swingable, adjusting lever provided with a tube slidably receiving the projection, and a crank pin on the rod engageable with and supported by a hitch assembly interconnecting the implement with the tractor for translating the swinging motion of the lever into an upward or downward movement of one end of the implement.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
97 words
Motion transmitting structure comprising: an elongated shaft; means for supporting said shaft for oscillation about its longitudinal axis and holding the same against axial movement; an elongated, lever irrotational about its longitudinal axis extending laterally from the shaft and swingable within a plane substantially parallel therewith; and a coupling for oscillating said shaft about said axis during swinging of said lever within said plane, said coupling including a lateral projection on the shaft swingable about said axis of the shaft during oscillation of the latter and a device rigid to the lever and rotatable on the projection.
Claim 2
Dependent Claim
97 words

Claim 3
Dependent Claim
28 words
Structure as claimed in claim 1, wherein said axis and said plane are horizontally disposed and said projection extends upwardly and outwardly from one end of the shaft.
Claim 4
Dependent Claim
26 words
Structure as claimed in claim 2, wherein said device is a tube and means is provided to hold the tube against axial movement along the projection.
Claim 5
Dependent Claim
20 words
Structure as claimed in claim 1, there being an angle between said axis and the projection of less than 90*.
Claim 6
Dependent Claim
27 words
Structure as claimed in claim 1, and a member disposed for engagement with the lever for holding the latter in said plane during swinging of the lever.
Claim 7
Dependent Claim
26 words
Structure as claimed in claim 5, wherein said member is disposed for free reciprocation of the lever along its longitudinal axis during swinging of the lever.
Claim 8
Dependent Claim
29 words
Structure as claimed in claim 1; and latching means for releasably holding the lever in any one of a number of selected positions along its path of swinging travel.
Claim 9
Dependent Claim
27 words
Structure as claimed in claim 7, wherein said latching means has associated therewith a member for holding the lever in said plane during swinging of the lever.
Claim 10
Dependent Claim
41 words
Structure as claimed in claim 8, wherein said lever has a pair of yieldably interconnected sections, one of which is disposed for retention by said member and the other of which is biased toward said latching means for releasable retention thereby.
Claim 11
Dependent Claim
26 words
Structure as claimed in claim 1, wherein is provided a crank on said shaft and a component for receiving torque from said shaft through said crank.
