Abstract
Abstract In the event that crop material is loaded into the baling chamber more heavily in one portion than another, the forming belt at the area of insufficient volume will become slackened relative to the remaining belts. Such slack condition is sensed by the monitor, and a signal device such as a light, buzzer or bell is actuated to indicate to the operator that additional crop material is needed in the deficient portion of the chamber so as to prevent the bale from becoming improperly shaped. The operator can thereupon take steps to assure that material is loaded in such a way as to make up for the deficiency.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
41 words
In a rotary baler, a crop loading monitor comprising: signal means; and apparatus operably coupled with said signal means for actuating the same when the diameter of a bale forming in said baler becomes less at one portion thereof than another.
Claim 2
Dependent Claim
41 words
In a rotary baler, a crop loading monitor comprising: signal means; and apparatus operably coupled with said signal means for actuating the same when the diameter of a bale forming in said baler becomes less at one portion thereof than another.
Claim 3
Dependent Claim
56 words
In a rotary baler as claimed in claim 1, wherein said baler includes driven web means tensioned to apply a compactive and rolling force to the bale during formation, said apparatus actuating said signal means in response to detecting variations in the force applied by the web means adjacent the middle and ends of the bale.
Claim 4
Dependent Claim
87 words
In a rotary baler as claimed in claim 1, wherein said baler includes a set of side-by-side, endless elements tensioned and driven lengthwise to apply a compactive and rolling force to the bale during formation, said apparatus including a pair of sensors positioned for operation by their respective elements adjacent opposite ends of the bale, an element adjacent the end of the bale being operable to operate its corresponding sensor when that particular element is slackened relative to the elements corresponding to the middle of the bale.
Claim 5
Dependent Claim
44 words
In a rotary baler as claimed in claim 3, wherein said signal means is electrically powered, said apparatus further including an electrical circuit associated with said signal means, the opening and closing of a path of said circuit being controlled by a said sensor.
Claim 6
Dependent Claim
38 words
In a rotary baler as claimed in claim 4, wherein each of said sensors includes a member engageable with its corresponding element and shiftable therewith to a position operating said circuit path when said corresponding element becomes slackened.
Claim 7
Dependent Claim
29 words
In a rotary baler as claimed in claim 5, wherein said signal means includes a pair of signal devices each operable independently of the other by their corresponding sensors.
Claim 8
Dependent Claim
60 words
In a rotary baler as claimed in claim 1, wherein said signal means includes a pair of signal devices corresponding to opposite ends of the bale being formed, each of said devices being operable independently of the other to signal the condition of the forming bale at the corresponding end thereof without regard to the opposite end of the bale.
