专利汇可以提供Twine measuring trip mechanism for balers专利检索，专利查询，专利分析的服务。并且A twine measuring mechanism for actuating the tying or knotting mechanism of a hay baler wherein the twine is pressed against a measuring wheel. The measuring wheel rotates in response to movement of the twine and actuates a gear train which selectively trips a switch and actuates the knotting mechanism. The length of the bales can be varied through the utilization of easily mounted interchanging measuring wheels.，下面是Twine measuring trip mechanism for balers专利的具体信息内容。
1. For use in a baler incorporating knotting apparatus and a twine supply, a twine measuring mechanism for actuation of the knotting apparatus in response to movement of a predetermined amount of twine, said, mechanism being positioned between the twine supply and the knotting apparatus for reception of the twine as it moves from the supply to the knotting apparatus, said mechanism comprising a twine measuring element engageable by the twine and movable in response to passage of the twine thereover, and control means operative in response to a predetermined movement of the twine measuring element to activate the knotting apparatus, said twine measuring element comprising a rotatably mounted measuring wheel engageable at a point on its periphery by the twine with the frictional engagement therebetween effecting a rotation of the wheel in response to movement of the twine.
2. The mechanism of claim 1 including a free rotating pressure wheel biased against the measuring wheel with the twine sandwiched therebetween whereby a continuing wheel turning engagement of the twine with the measuring wheel is effected.
3. The mechanism of claim 2 wherein the control means comprises a measuring wheel driven gear train, said gear train driving a cam, and means responsive to movement of the cam to actuate said knotting apparatus.
4. For use in a baler incorporating knotting apparatus and a twine supply, a twine measuring mechanism for actuation of the knotting apparatus in response to movement of a predetermined amount of twine, said mechanism being positioned between the twine supply and the knotting apparatus for reception of the twine as it moves from the supply to the knotting apparatus, said mechanism comprising a twine measuring element engageable by the twine and movable in response to passage of the twine thereover, and control means operative in response to a predetermined movement of the twine measuring element to activate the knotting apparatus, said twine measuring element comprising a rotatably mounted measuring wheel engageable at a point on its periphery by the twine with the frictional engagement therebetween effecting a rotation of the wheel in response to movement of the twine, a free rotating pressure wheel biased against the measuring wheel with the twine sandwiched therebetween whereby a continuing wheel turning engagement of the twine with the measuring wheel is effected, the control means comprising a measuring wheel driven gear train, said gear train driving a cam, and means responsive to movement of the cam to actuate said knotting apparatus, the means responsive to movement of the cam comprising an electric switch and knotting apparatus releasing solenoid electrically connected to the switch and responsive to a cam operation oF the switch for effecting an actuation of the knotting apparatus.
5. The mechanism of claim 4 wherein said measuring wheel is removably mounted for selective replacement by measuring wheels of different sizes so as to vary the movement time of the cam and hence the frequency of actuation of the knotting apparatus and the size of the bale produced.
6. For use in a baler incorporating knotting apparatus and a twine supply, a twine measuring mechanism for actuation of the knotting apparatus in response to movement of a predetermined amount of twine, said mechanism being positioned between the twine supply and the knotting apparatus for reception of the twine as it moves from the supply to the knotting apparatus, said mechanism comprising a twine measuring element engageable by the twine and movable in response to passage of the twine thereover, and control means operative in response to a predetermined movement of the twine measuring element to activate the knotting apparatus, the control means comprising a twine measuring element driven gear train, said gear train driving a cam, and means responsive to movement of the cam to actuate said knotting apparatus, the means responsive to movement of the cam comprising an electric switch and knotting apparatus releasing solenoid electrically connected to the switch and responsive to a cam operation of the switch for effecting an actuation of the knotting apparatus.
7. The mechanism of claim 6 wherein said twine measuring element comprises a rotatably mounted measuring wheel engageable on its periphery by the twine with the frictional engagement therebetween effecting a rotation of the wheel in response to movement of the twine.
